Description

{Tree-anchor adiabatic construction method}

More particularly, the present invention relates to an external heat insulating panel having a strength and a hardness to withstand external physical shocks or vibrations, By providing an external insulation structure consisting of tree anchors that exhibit the primary and secondary tucking forces to secure the panel to the outer wall, the tree anchors that amplify the service life and enhance the competitiveness of the outer insulation construction that is easy to construct And to other insulation methods of buildings.

Generally, wall panels are classified into wet and dry methods.

The wet method is a method in which cement mortar is applied to the back surface of the wall panel and then the cement mortar is applied to the building wall. However, it takes a long time to cement the mortar and cement mortar is properly cured There is a problem that the wall panel is detached from the building wall even if there is little impact, thereby causing a safety accident.

The dry method is a construction method in which a wall panel is physically attached to a building wall by using an anchor bolt and an angle. There is no need to cure the cement mortar and the building panel is not detached from the building wall. However, It is not easy to install the bolts and the angles on the outer wall of the building, which increases the construction period and construction cost.

Recently, a lot of attempts have been made to maximize the merits of both construction methods by using a wet method and a dry method in combination. For example, a construction method of a building exterior panel of Patent Registration No. 10-0845245 (registered on July 3, 2008) As shown in Fig. 1, a food line is horizontally and vertically arranged on an outer wall of a building, and a fixing member having a base plate and a toothed portion piercing upward from the end of the base plate is fixed And then the panel having the backside of the adhesive coated in some places adjacent to the edge of the fixing member is folded adjacent to the first EPS board, the second EPS board, the first EPS board and the second EPS board A reinforcement board attached to the front surface of the first EPS board, and a fine layer formed on the front surface of the reinforcement board, wherein the toothed portion of the fixing member has a second EPS And the first EPS board is penetrated to the middle of the first EPS board so that the panel is installed on the outer wall of the building due to the adhesive and the fixing member, and the toothed end of the fixing member is bent so that the bent line is sharp And when the toothed portion is embedded in the panel, the folded portion of the toothed portion is hooked with the glass fiber mesh.

However, in the case of the construction method of the panel for building outer wall as described above, since the bent portion of the toothed portion is fixed by hanging the glass fiber mesh, it is difficult to apply it to a general wall panel not provided with a glass fiber mesh.

As another example of the related art, in an insulating panel fastener of Korean Patent No. 974922 (Aug. 03, 2010), a heat insulating panel such as a foam resin panel is fixedly coupled to a corner portion of a building A sawtooth tooth portion is formed so as to be vertically bent and raised in one direction only at two opposing corners of the rectangular base plate portion so as to have an entirely trapezoidal shape, A hinge portion is formed so as to be bent, and either a through hole for fastening the piece or an inverted barb portion protruding laterally is formed on the tooth forming the tooth portion.

In addition, as another example of the related art, as shown in FIG. 3, a bracket for external installation for preventing fall of a finish board of Korean Patent Laid-Open Publication No. 2013-91457 (2013.08.19) The present invention relates to a bracket for an outer wall of a building, which is installed in an outer wall of a building in a checkerboard arrangement, for constructing an insulating panel made of an EPS insulating board on the outer wall of the building, An upward upwardly bent plate formed by bending upward from the front end of the horizontal support plate and a downwardly bent upwardly bent plate extending downward from the front end of the horizontal support plate; And an extended support plate horizontally extending from the front end of the horizontal support plate in the front direction The bottom face of the heat insulating board is supported by the upward supporting plate and the upper face of the heat insulating board is supported by the upward supporting plate, And the finishing board of the heat insulating panel is inserted and fixed between the extended support plates.

However, the conventional bracket (or fixture) is fixed directly to the wall surface by a fixing means such as a direct screw or a nail. In this case, the operation of fixing the bracket to the wall surface by the fixing means There is a problem that it is very difficult.

In addition, in the conventional bracket, since the portion to be inserted into the external heat insulating panel is formed in a simple triangular or saw-tooth shape, there is a problem that the external heat insulating panel can be easily detached from the bracket during use for a long time.

In addition, a conventional external heat insulating panel (also referred to as a " heat insulating board ") is composed of an external board having hardness and an internal board having a heat insulating property fixed to the inside of the external board, and the external board includes a cement board, Board or gypsum board.

However, the conventional outer board is weak in strength and hardness, and is easily broken due to external physical impact or vibration. As a result, there is a problem that the use period of the external heat of the building is short, and the competitiveness of the product is weakened.

In addition, since the conventional external thermal insulation panel is installed in a state exposed to the outside, the adhesive for fixing the outer board and the inner board is easily deteriorated by the direct sunlight of the solar heat, so that the adhesion between the outer board and the inner board is lost So that the outer board having a heavy load can easily fall off.

It is an object of the present invention to provide an outer heat insulating panel having strength and hardness to withstand external physical impacts or vibrations and to secure the outer insulating panel to the outer wall. It is possible to increase the service life by providing the external insulation structure composed of the tree anchors exhibiting the first and second tipping tacks and to improve the competitiveness of the outer insulation construction which is easy to construct, And to provide an external heat insulating method.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings (the same reference numerals are used for the same components as the conventional ones, and a detailed description thereof will be omitted).

≪ Embodiment 1 >

The external heat insulating structure of the building of the first embodiment is composed of a tree anchor 1 fixed at an outer wall of a building at a fixed interval and a plurality of external heat insulating panels 2 fixed to an outer wall by the tree anchor 1 .

The tree anchor (1) comprises at least one upper and lower insertion portions (10) (20) symmetrically formed so as to insert and fix outer heat insulating panels (2) And a gap holding part (30) extending from the center of the lower insertion part (10) (20) to maintain a state in which the external heat insulating panel (2) is spaced apart from the external wall at a predetermined interval, And a fixing part 40 extending downward and fixed to the outer wall.

The upper inserting portion 10 is inserted into the lower end of the outer heat insulating panel 2 located on the upper portion of the outer heat insulating panel 2 adjacent to the upper and lower sides with the tree anchor 1 as a center and exerts a fixing force.

The upper insertion portion 10 includes a first pointed end 12 having a pointed end like an arrowhead and a second pointed end 12 extending inward from the lower end of the first pointed end 12 at a certain depth, At least one first barb 16 is formed to extend easily after being inserted into the outer surface 14 and the outer heat insulating panel 2.

The first apical surface 12 preferably has a shape of an arrowhead having a pointed end so as to be smoothly inserted into the outer heat insulating panel 2. [ Of course, the present invention is not limited to this, and any shape can be used as long as it can be easily inserted into the external heat insulating panel 2 and can be easily removed.

The first enlarged surface 14 forms a surface extending downward from a position of being recessed at a certain depth from the end of the first apex surface 12 to a depth of the outer surface of the first apex surface 12, So that the fixing force is improved.

The first barb 16 is formed in a direction opposite to the direction of insertion of the outer heat insulating panel 2 so as to prevent the outer heat insulating panel 2 from being easily detached from the upper insertion portion 10 toward the gap holding portion 30 And is formed such that the end thereof protrudes sharply while being downward. In addition, the first barb 16 may be provided on one side of the first apical surface 12.

The lower insertion portion 20 is preferably formed in a shape symmetrical with the upper insertion portion 10.

The lower insertion portion 20 is inserted into the upper end of the external heat insulating panel 2 located at the lower one of the external heat insulating panels 2 neighboring upward and downward around the tree anchor 1 and exerts a fixing force.

The lower insertion portion 20 includes a second distal end surface 22 having a sharp end like an arrowhead and a second distal end surface 22 extending inward from the lower end of the second distal end surface 22, An enlarged surface 24, and at least one second barb 26 for preventing easy detachment after being inserted into the outer heat insulating panel 2.

It is preferable that the second apical surface 22 is in the form of an arrowhead having a pointed end so as to be smoothly inserted into the outer heat insulating panel 2. [ Of course, the present invention is not limited to this, and any shape can be used as long as it can be easily inserted into the external heat insulating panel 2 and can be easily removed.

The second extended surface 24 forms a surface extending downward from a position recessed at a certain depth from the end of the second apical surface 22 so that an area inserted into the external thermal insulating panel 2 So that the fixing force is improved.

The second barbs 26 are formed in a direction opposite to the direction of insertion of the outer heat insulating panel 2 so as to prevent the outer heat insulating panel 2 from being easily pulled out from the lower insertion portion 20 toward the gap holding portion 30 It is preferable that the end is formed so as to protrude sharply while being upward. In addition, the second barb 26 may be provided on one side of the second apical surface 22.

The interval holding portion 30 is formed to be spaced apart from the upper and lower insertion portions 10 and 20 by a distance between the upper and lower insertion portions 10 and 20 and the fixing portion 40, So that the central portion of the outer heat insulating panel 2 can be inserted and fixed so that the fixing force can be exerted. For example, when the upper and lower inserting portions 10 and 20 are inserted into the front or rear end portions of the outer heat insulating panel 2, a smooth fixing force can not be exhibited.

The fixing portion 40 extends downward from the end of the gap holding portion 30 and is fixed to the outer wall so that the outer heat insulating panel 2 exerts a fixing force so as to be kept fixed to the outer wall.

4 and 5, the fixing part 40 is fixed to the outer wall of the fixing bracket 50 so that the fixing part 40 is fixed by the fixing bracket 50. In this case, . Of course, in some cases, the fixing portion 40 may be directly fixed to the outer wall through fixing means such as a direct bolt or an anchor bolt.

The fixing bracket 50 includes a plurality of fixing pieces 52 fixed at both ends by fixing means on the wall surface and a plurality of fixing pieces 52 formed between the plurality of fixing pieces 52, And an insertion piece 54 for inserting the insertion portion 54 into the insertion hole 54.

The outer heat insulating panel 2 is a means for fixing the outer wall of the building to the outer wall of the building as well as the outer heat of the building.

The outer heat insulating panel 2 includes an outer board 2a which is exposed to the outside and is designed to be able to decorate the outer wall and an inner board 2b which is formed inside the outer board 2a and exhibits thermal insulation performance, .

The outer board 2a is composed of an inorganic binder-1 and an inorganic binder-2.

The inorganic binder-1 may include 60 to 92% by weight of calcium aluminate (CaO Al ₂ O ₃ ), 5 to 20% by weight of metakaolin, 1 to 15% by weight of a polymer synthetic resin, and 1 to 5% Is selected so that the ratio of each component is 100% by weight in total.

The calcium aluminate is a melted material such as alumina, calcium oxide, CaO and anhydrous silicic acid, and CaO.Al ₂ O ₃ is mixed with a clay having a large alumina content, such as limestone, bauxite or alumina shale, as a main mineral, And then cooled to obtain a fine powder. An alumina content of 80% or more and a brain surface area of 4,000 m < 2 > / g was used. Such calcium aluminate is used in an amount of 60 to 92% by weight based on the total weight of the composition. When the weight of the calcium aluminate is less than 60% by weight, the strength of the calcium aluminate is lowered.

The meta-kaolin is a basic formula of a highly purified clay is _{Al 2 Si 2 O 5 (OH} ) 4. This is doubled as a natural thickening material when used in combination with a polymer thickening material, and also helps to maintain high strength by reacting with calcium aluminate. The blend ratio is preferably 5 to 20% by weight. For example, when the content is less than 5% by weight, the reaction is insufficient. When the content is more than 20% by weight, the thickening effect may be enhanced, but the strength may decrease due to excessive reaction with calcium aluminate.

The polymer synthetic resin is an admixture material for preventing lifting of the flooring due to the difference in impact, shrinkage and expansion coefficient due to changes in the external environment and improving the durability of the flooring by imparting adhesiveness, flexibility and abrasion resistance. The polymer synthetic resin applicable to the subject matter is preferably vinyl acetate (Vinylacetate).

The polymer synthetic resin is preferably 1 to 15% by weight. For example, when the content is less than 1% by weight, the polymer synthetic resin does not play a role. When the content is more than 15% by weight, the viscosity due to the polymer is high, which may interfere with the calcium aluminate.

Preferably, the thickening material is mecellose (MC, MECELLOS). The above-mentioned mecellose is a water-soluble polymer prepared by substituting a hydroxyl group (-OH) methoxyl group (-OCH3) and a hydroxypropoxyl group (-OCH2CH (OH) CH3) in a cellulosic molecule through an esterification method. The viscosity of the material is preferably 40us 40,000 cps. The above-mentioned thickening material maintains an appropriate viscosity, thereby enhancing workability and initial adhesion. The blend ratio is preferably 1 to 5% by weight. For example, when the content is less than 1% by weight, the viscosity is weak and the workability is good, but the initial adhesion may be decreased. When the content is more than 5% by weight, the viscosity is high and the initial adhesion is good.

On the other hand, the inorganic binder-1 and water should be mixed at a weight ratio of 1: 0.4 to 0.5 at 200 to 500 rpm for 3 to 5 minutes. If the mixing ratio of the inorganic binder-1 and water is less than 1: 0.4, it is difficult to mix the materials. If the ratio is more than 1: 0.5, the spacing of the branch chains in the formation of calcium aluminate ettringite is too long, It can fall significantly. Further, the inorganic binder-1 composition is metered and stirred in a powder agitator for 30 minutes or more to prepare a premix powder.

The inorganic binder-2 may include 60 to 92% by weight of calcium aluminate (CaO Al ₂ O ₃ ), 5 to 20% by weight of silica powder, 1 to 15% by weight of polymer synthetic resin, 1 to 5% And 1 to 5% by weight of fogging material are selected so that the proportion of each component is 100% by weight in total.

The calcium aluminate (CaO Al ₂ O ₃ ) is the same as the inorganic binder-1 and its detailed description is omitted.

The silica powder preferably has an SiO ₂ content of 99.7% or more, an acid resistance, an alkali resistance and a hardness, and a very low thermal expansion, electrical conductivity and abrasion resistance, and the amount thereof is preferably 5 to 20% by weight . For example, when the amount of the abrasion-resistant material is less than 5 wt%, the effect of the abrasion-resistant material is less likely to be exhibited. When the amount of the abrasion-resistant material is more than 20 wt%, the amount of calcium aluminate and other mixed materials may be reduced.

The polymer synthetic resin is the same as the inorganic binder-1, and a detailed description thereof will be omitted.

The above-mentioned inherent dynamic material is characterized in that it is 18 cm or more when measured by naphthalene-modified residual green slump. It is preferable to use 1 to 5% by weight based on the total weight of the subject. For example, when the content is less than 1% by weight, the flowability of the material is remarkably low and deposition on the nonwoven fabric is difficult. When the content is more than 5% by weight, material disadvantages may occur due to differences in specific gravity of the materials.

The fogging material is used to prevent bubbles from being generated in the mixed liquid during the mixing and stirring process, and a polyalkylene oxide such as polyethylene oxide, polypropylene oxide, or a silicone can be used. It is preferable that the amount thereof is 1 to 5% by weight. For example, when the content is less than 1% by weight, bubbles may be generated during the production process or actual coating, and the quality of the product may be reduced. When the content is more than 5% by weight, the surface tension may be difficult to maintain.

Meanwhile, the inorganic binder-2 and water should be mixed at a weight ratio of 1: 0.3 to 0.35 at 200 to 500 rpm for 3 to 5 minutes. If the mixing ratio of the inorganic binder-1 and water is less than 1: 0.3, it may be difficult to deposit on the nonwoven fabric. If the inorganic binder-1 and water are mixed more than 1: 0.35, flowability may be too high. Further, the inorganic binder-2 composition is metered and stirred in a powder agitator for 30 minutes or longer to prepare a premix powder.

The inner board 2b is fixed to the inside of the outer board 2a to insulate the outer wall of the building.

The inner board 2b is preferably a foamed polystyrene (EPS) board or a urethane foam. Of course, the present invention is not limited thereto, and any material that is used to insulate the building can be used.

It is preferable that the outer heat insulating panel 2 is formed by cutting the outer board 2a and the inner board 2b to a predetermined size.

The outer heat insulating panel 2 may be made of an adhesive to amplify the fixing force between the outer board 2a and the inner board 2b. Of course, since the outer board 2a has a self-adhesive force, the adhesive may be omitted in some cases.

The outer insulation method of a building using the tree anchor constructed as described above will be described below.

The step S1 of manufacturing and finishing the outer insulating panel is performed by forming the inner board 2a through the composition of the inner board 2a described above and then bonding the outer board 2a to the inner board 2b, And the inner board 2b are bonded together to form the outer heat insulating panel 2.

Then, the external heat-insulating panel 2 is cut according to the standard.

The tree anchor manufacturing step S2 is manufactured through a sheet metal process for cutting and bending one metal sheet.

That is, as shown in Fig. 6, the tree anchor 1 is formed by one metal plate.

Subsequently, as shown in Fig. 7A, an outer frame is formed on the plate material. That is, the upper and lower inserting portions 10 and 20 are formed symmetrically.

As shown in Fig. 7B, each of the upper and lower inserting portions 10 and 20 with the outer peripheries is interwoven with each of the upper and lower inserting portions.

7C, the upper and lower inserting portions 10 and 20 are formed on the front side, and then the lower side inserting portion 10 and the lower inserting portion 20 are bent downward by a predetermined width to form the gap maintaining portion 30 and the fixing portion 40 , The final tree anchor (1) is produced.

The manufacturing method of the tree anchor 1 as described above is described by way of example only, but it is not limited thereto. In some cases, each of the components may be manufactured separately, and then they may be integrated by welding or the like.

The tree anchor fixing step (S3) fixes the tree anchor (1) manufactured through the tree anchor manufacturing step (S2) to the outer wall.

In this case, the fixing part 40 of the tree anchor 1 is fixed directly to the outer wall through fixing means such as a direct bolt or an anchor bolt.

Or the fixing bracket 50 is fixed to the outer wall by fixing means and then the fixing portion 40 is inserted into the insertion piece 54 of the fixing bracket 50 so that the tree anchor 1 is fixed to the outer wall can do. This can be selected according to the purpose of use and construction method.

In the step of fixing the external panel (S4), one end of the external heat-insulating panel (2) is fixed by the tree anchor (1) fixed to the external wall at regular intervals through the step of fixing the anchors (S3).

That is, as one side of the inner board 2b of the outer heat insulating panel 2 adjacent to each of the upper and lower inserting portions 10 and 20 of the tree anchor 1 fixed to the outer wall is inserted, (10) and (20).

The secondary anchoring force of the external heat insulating panel 2 is exerted by the first and second barbs 16 and 26 formed on the upper and lower inserting portions 10 and 20 so that the trianchor 1 is prevented from being damaged, The external heat-insulating panel 2 is fixed firmly.
