Bonding Spacing Material, Reinforcement Spacing Structures and Construction Methods Using it}

The present invention relates to a binding spacer capable of connecting both members spaced apart by simple manual work and fixing it by bolting, and a structure and method for maintaining the spacing between reinforcing bars using the same.

The reinforced concrete structure applied to the building is a composite structure using the tensile-resistance characteristics of rebar and the compression-resistance characteristics of concrete. When constructing a reinforced concrete structure, a formwork that forms the outer surface of the concrete is installed, reinforcement is placed on the formwork to match the design strength of the structure, and the concrete is poured. When the curing is completed, the formwork is removed.

However, it takes a lot of time to install and dismantle the formwork, and the formwork damaged during dismantling cannot be recycled, so it has disadvantages such as waste of materials and industrial waste caused by waste materials.

There is a method of using a deck plate in the slab section of each floor of a building as a formless construction method to solve the above shortcomings. The use of the deck plate eliminates the need for formwork construction and dismantling, reduces the generation of industrial waste, facilitates wiring and pipe installation under the deck plate, enables safe work, and shortens the overall construction period. In addition, it is possible to shorten the air required for reinforcing reinforcement by using the deck plate shipped in a state in which the truss muscle composed of a combination of the lattice muscle, the upper chord and the lower chord is coupled to the upper surface of the deck plate.

These deck plates are fixed with both ends mounted on the reinforced concrete beam member. The fixing operation of the deck plate is to prevent horizontal movement during the concrete pouring operation. Conventionally, hooks at both ends of the connecting material are hung on the connecting reinforcing bars embedded and protruding in the beam members, respectively, and the truss bars coupled to the upper deck plate, It proceeded by welding the contact point.

However, since such a welding operation always accompanies the risk of fire, a fire countermeasure must be prepared together, and the manpower and time required for the welder increase the construction cost and delay the construction period.

Utility model registration 20-0186281 "Reinforcing bar connection for deck plate" and other prior arts provide a means to fix the installation state of the deck plate without welding work, but such prior art is a beam member connecting reinforcing bar and deck plate truss There is a limitation in that it can be applied only when the distance between the roots of the muscles is maintained within an extremely limited range.

In order to solve this problem, registered patent 10-2099401 "Tension fastening device by rotational induction" provides a device that can be fixed by applying tension by rotational induction by connecting both members spaced apart and pulling the band. However, since the manufacturing cost is high due to the complexity of the configuration and considerable labor is required in the process of manually pulling the band, a simple structure and a connection member capable of simplifying the connection operation and a connection structure using the same are needed.

At this time, the fastening holes 210 of the male member 200 are formed in a certain number, and the bolt 300 may be inserted into only one or a plurality of the fastening holes 210 , but the slit holes 110 of the female member 100 are formed. ) is formed in a straight line, so long as the slit hole 110 can communicate with one or more fastening holes 210, the bolt 300 can be inserted at any position.

In summary, the binding spacer of the present invention can change the length of the entire binding spacer by changing the fitting distance of the male member 200 inserted into the channel space according to the spacing of the existing reinforcing bars. After mounting, the slit hole 110 of the arm member 100 and the bolt 300 are inserted and fastened through one or more fastening holes 210 communicating with the slit hole 110, so that the gap between the existing reinforcing bars is It can be fixed while maintaining a predetermined interval.

In addition, when the first and second clasps are stacked on the same side, the body of the male member 200 may be configured to be completely accommodated in the channel space.

This will be described with reference to FIG. 3 .

In FIG. 3 , the male member 200 is inserted into the channel space of the female member 100 , and the first and second clasp parts 120 and 220 , which are rings of each member, may be stacked on the same side. In addition, through this configuration, the volume of the binding spacer according to the present invention is reduced during storage and movement, thereby saving space for storage, thereby reducing storage costs.

In addition, the body of the male member 200 is repeatedly formed with convex portions 230 on the front and rear surfaces, and on the inner surface of the rear surface of the female member 100 , recessed portions engaged with the convex portions 230 corresponding to the convex portions 230 . (凹部) 130 may be configured to be repeatedly formed.

Referring to FIG. 1 , the recesses 130 are formed at regular intervals inside the rear surface of the arm member 100 , and in more detail, grooves formed to a constant depth are repeatedly disposed.

Referring to FIG. 1 , in the convex part 230 , protrusions formed at a predetermined height are repeatedly disposed on the front and rear surfaces of the male member 200 . In addition, with reference to [FIG. 3], the protrusion shape of the convex part 230 can be confirmed in more detail.

The recess 130 and the convex part 230 may be formed to correspond to each other or to be inserted into each other, and when the male member 200 is inserted into the female member 100, the convex part (130) 230) is interlocked or inserted to prevent sliding left and right when fastening and fixing the nut 400 to the bolt 300.

In addition, the concave portion 130 and the convex portion 230 may be formed in various shapes other than a straight line formed in the vertical direction.

It will be described with reference to [Fig. 4] to [Fig. 5].
