Description

Method of constructing earthquake-proof ALC house

In the present invention, even if a house is built with lightweight aerated concrete (ALC: Autoclaved Lightweight Concrete), which has a compressive strength that is 7 times lower than that of general concrete, the ALC wall longitudinal (main), frame reinforcing section and ALC slab section steel are provided from the concrete foundation. It relates to a seismic ALC house construction method that satisfies seismic resistance by forming a skeleton as if the ALC wall and slab are connected together through the structure.

It is proposed that a conventional ALC block for a wall and an ALC panel for a slab are disclosed in Patent Documents 1 and 2.

In the ALC block for walls of Patent Document 1, horizontal reinforcing bars and longitudinal reinforcing bars are arranged on the wall and horizontal adjustment of the blocks.

The ALC panel for slab of Patent Document 2 has improved strength against a bending load through a lower iron plate.

These conventional ALC blocks for walls and ALC panels for slabs are built for wall or slab purposes like ordinary houses without considering earthquake resistance, and there is a high risk of being easily collapsed even with weak earthquake resistance.

The reason for being weak against seismic resistance is that the concrete foundation, ALC wall and slab, longitudinal and transverse reinforcing bars, etc. were not constructed like a frame (like reinforced concrete) connected to each other.

The present invention has been conceived to solve the above-described problem, and provides a seismic ALC housing construction method that can withstand seismic resistance with ALC having very low compressive strength by connecting like a single frame from a concrete foundation to a wall and a slab. There is a purpose.

In order to achieve the above object, the seismic ALC housing construction method according to claim 1 of the present invention comprises the steps of: forming a foundation with concrete on the ground; Forming an ALC base layer by placing an ALC block for base along the rim of the base concrete; Adjusting the level of the ALC base layer with respect to the foundation; After the level is adjusted, driving a strong anchor to the base concrete through a vertical through-hole formed in the center of the ALC block for each base of the ALC base layer; Fastening and fixing a male threaded longitudinal muscle to the strong anchor; Bonding the base concrete and the ALC base layer by injecting mortar through the through hole after the jonggeun is fastened and fixed; Forming a first ALC block masonry layer for walls on the ALC base layer so that the longitudinal roots are disposed inside the grooves formed by contacting the half grooves formed on the side surfaces of the masonry ALC blocks; Forming a plurality of wall ALC block masonry layers by repeating the first ALC block masonry layer for walls; Placing a steel pipe fixed to the left and right sides of an opening lintel on the upper or lower side of an opening such as a window or an entrance among the plurality of wall ALC block masonry layers while being sandwiched between the longitudinal roots; Filling by injecting mortar through the grooves when the plurality of wall ALC block masonry layers are completed; Placing a T-beam for reinforcing an edge in contact with the upper and inner surfaces of the top and inner surfaces of the plurality of ALC block masonry layers for the wall after the filling is completed; Placing a cross-shaped steel for slab across the front or rear or left and right of the T-beam for reinforcing the rim while being fitted to the longitudinal root; Placing an ALC panel between the cross-shaped steels for the slab while being fitted to the longitudinal roots; After the ALC panel is laid, the step of fastening and connecting to the lower side of the cross-shaped steels for the slab with a transverse muscle, which is a male threaded rod.

The seismic ALC house construction method according to claim 2 of the present invention includes the steps of connecting and reinforcing transverse muscles, which are male threaded rods, along an edge to at least one of the masonry layers of the ALC block for walls, and the transverse muscles cut off at the opening. It further comprises the step of fastening the end of the female screw washer and a nut.

According to the present invention, there are the following effects.

Since the male threaded longitudinal bar is fastened to the anchor embedded in the concrete foundation, it behaves as a single reinforcing bar and is strong against seismic resistance.

In addition, the wall and the slab are connected like a single frame based on the vertical axis, so that the entire house is formed like a single frame, enabling earthquake resistance according to the earthquake type.

In particular, the T-beam for rim reinforcement placed along the uppermost edge and the cross-shaped steel for slab that spans the T-beam for rim beams are integrally connected through the longitudinal and transverse bars for connection, so that the seismic resistance is very excellent.

In addition, since the female thread washer and the nut are fastened to the transverse root of the part that breaks from the opening for final finishing, when using a normal washer, it is prevented from continuing to push the normal washer into the ALC block when it is tightened with a nut, causing damage or depression.

General washers are easy to apply because they are in close contact with hard concrete or wood with elasticity and are not depressed even when surface pressure is applied.However, in the case of an ALC block that is not elastic and is not rigid, the female screw washer is attached to the transverse root. Even if it is continuously tightened, it will not be pushed in to prevent dents.

1 to 10 are views sequentially showing a seismic ALC housing construction method according to a preferred embodiment of the present invention.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings, in which all four sides are not shown, but only the front and one side are shown, so that the walls and slabs of the entire house are formed.

1 to 10 are diagrams sequentially showing a seismic ALC house construction method according to a preferred embodiment of the present invention.

When the foundation (F) is completed, the ALC blocks (1a) for the base end are placed on four sides along the circumference of the upper surface of the base (F) as shown in FIG. 2.

When the ALC base layer (a) is formed by placing the ALC blocks (1a), the height of the upper surface of the ALC base layer (a) with respect to the base (F) is adjusted using the leveling unit 10 as shown in FIG. 3.

As shown in Figs. 2 and 3, the ALC block 1a for the base end has a center through hole 3a and three holes 5a around it.

The three holes 5a are provided with a horizontal adjustment unit 10.

The horizontal adjustment unit 10 includes a nut 11 fixed to the hole 5a and a lifting bolt 13 fastened to the nut 11.

A socket (13a) is formed on the upper surface of the lifting bolt (13), and leveled by lifting according to the rotation of the lifting bolt (13) using a tool (T).

After leveling the height of the upper surface of the ALC base fault layer (a), as shown in FIG. 4, the strong anchor 15 is driven into the foundation F through the through hole 3a, and the vertical root 20 sealed with the male thread is the strong anchor 15 ) Is fastened and fixed.

The strong anchor 15 is first inserted into the hole, which is a groove drilled in the foundation (F), and then penetrated and fixed by expanding the wing with a blow or the like.

After the longitudinal root 20 is fastened to the strong anchor 15, the mortar is injected through the through hole 3a to be filled.

After the mortar is cured, the first ALC block masonry layer (b) for walls is placed on the ALC base layer (a) as shown in FIGS. 5 and 5A.

The first ALC block 1b of the first ALC block masonry layer b for a wall has half grooves 3b formed on both left and right sides.

Accordingly, when placed sideways between the first ALC blocks 1b, the half grooves 3b merge to form the grooves 3, and the longitudinal roots 20 are arranged in the grooves 3.

In addition, when the transverse root 25 broken at the entrance opening EP or the window opening WP is seen as shown in FIG. 7, the female screw washer 26 and the nut 27 are fastened as shown in FIGS. 5B and 5D to finish, and mortar. Is poured into the transverse root mounting groove (5).

The female thread washer 26 includes a flange 26a extending to one side at the center and a female thread 26b formed on the inner surface of the flange 26a.

Accordingly, since the female screw washer 26 remains fastened to the transverse root 25, it is no longer pushed even if the nut 27 is tightened and entered, thereby preventing the ALC block from being depressed due to the washer.

Similarly, the longitudinal root 20 on the lower surface of the window opening WP of FIG. 7 may be finished by fastening with a female screw washer and a nut in the same manner.

After the mortar is poured into the transverse root mounting groove 5, a second ALC block 2b is placed thereon, and a second ALC block masonry layer c for a wall is formed as shown in FIG. 6.

The second ALC block 2b is a block in which half grooves 3a are formed on both side surfaces, and functions the same as the first ALC block 1b.

When the second ALC block masonry layer (c) for walls is formed, the first ALC block masonry layer (b) and the second ALC block masonry layer (c) are alternately stacked to form a plurality of wall ALC block masonry layers (d to f). Is formed.

At this time, as shown in FIG. 7, if there is an opening for an entrance (EP) and an opening for a window (WP), the wall to the height of the opening (EP) (WP) before stacking a plurality of ALC block masonry layers (d to k) for walls For forming the ALC block coarse layer (d~i).

In this state, when the lintel 30 for the opening is horizontally hung above the opening WP, the lintel 30 supports the weight of the upper side.

Includes a male threaded rod 34 inserted through, a fastening element 35 that is fastened before and after the male threaded rod 34, and a steel pipe 37 that is fixed to the left and right ends of the iron plate 31 to which the longitudinal roots 20 are inserted. do.

Since the asphalt (AP) adhesive is adhered to the front and rear surfaces of the steel plate 31, the elasticity and waterproofing are satisfied at the same time as the fastening element 35 is pulled.

Likewise, the fastening element 35 is preferably composed of a female screw washer 35a and a nut 35b.

In this way, the lintel 30 placed on the upper side is called a lintel, and the lintel placed on the lower side is called a lowerin room. Accordingly, in this embodiment, the lintel 30 for the opening may be placed on the upper side, the lower side, or the upper and lower sides.

After the lintel 30 for the opening is over, the ALC block masonry layer (h) is completed, and the ALC block masonry layer (i, h) for the wall is formed again (see FIG. 8).

When all the wall ALC block masonry layers (b to h) are formed, mortar is injected and filled through the grooves 3 communicating with each other vertically.

When the filling of the mortar is completed in the groove 3, as shown in Fig. 8, mortar is applied along the circumference of the uppermost wall ALC block masonry layer (h), and a T-beam 40 for frame reinforcement is placed thereon. , Chonggeun (20) is put in place.
