Description

Dismantlement Deck plate Spacer < RTI ID = 0.0 >

The present invention relates to a spacer for a deformation-type deck plate, in particular, a lower end of a spacer and a form plate can be easily coupled to each other in the form of a hook in a state in which a lower end of a truss girder is engaged with a welded joint.

Generally, the concrete structure is a composite structure in which concrete, which is a compressive material, and reinforcing bar, which is a tensile material, are jointly used. After the formwork is constructed, reinforcing steel is inserted and then concrete is laid.

The concrete structure is a method for casting concrete. First, it is necessary to install the form by using plywood and grout, and to insert the reinforcing steel into the formwork and then to dismantle the concrete, curing and form. .

In order to solve this problem, a deck plate which can be supported in concrete during the curing of the concrete and concrete laid on the foundation between the beams, which is a structure for constructing the concrete structure, has been proposed.

Typically, the decking deck plate did not separate the form boards after concrete curing, but the cracks often occurred due to the inhomogeneity of the concrete material. Such cracks lead to leakage phenomena and rust on the formers. Decking deck plates were developed to detach form plates after conical curing. In the case of such a deformation-type deck plate, the shape plate is removed, and the point of leakage due to the crack can be easily found, which is a great advantage for maintenance and reinforcement. The decking deck plate is usually provided with a truss girder on the upper part of the formwork board, a connecting hole is provided on the lower part of the truss girder and is detachably coupled by a bolt penetrating the formwork, Lattice material.

However, a through hole is formed in the form plate so that the bolt penetrating through the form plate is screwed into the connection hole, and the productivity is lowered due to an increase in the number of steps in the process of forming the female thread in the connection hole.

In addition, in the process of separating the form board, all the bolts have to be unscrewed and there is another problem that the working time is delayed and the air is lengthened.

The present invention can increase the productivity by reducing the number of processes so that the formwork is coupled to the lower end of the spacer at the hook, and the workability can be improved so that the formwork can be easily separated.

The present invention relates to a spacer (S) for a deformation-type deck plate provided between a truss girder (T) and a formwork (P), wherein the spacer (S) The spacer body 20 is formed by integrally forming an elastic engagement portion 220 on the lower portion of the cylindrical body portion 210. The elastic engagement portion And a plurality of hooking pieces 221 are formed downward and a hook piece 222 extending outward at a lower end of the hooking piece 221 is formed, The hooking piece 221 is integrally formed with a hooking groove 225 on the outer surface of the hooking piece 221. The hooking groove 225 is formed on the lower surface of the body part 210 and the upper surface of the hooking piece 222, (224), and the engaging groove (225) is formed by a depth not less than the thickness of the formwork (P) And a resiliently engaging portion 220 of the spacer body 20 is securely engaged with the engaging hole H of the form plate P so that a load on the form plate P is supported .

In addition, the spacer body 20 is inserted only on both sides of the lower portion of the connecting rod 10 according to a load.

In addition, the cut-away space 223 is formed to have one of a straight shape, a wedge shape, and a cross shape.

In addition, the connecting rod 10 is characterized in that the reinforcing bending piece 101 is formed on both sides of the lower portion bent in a mountain shape.

According to the present invention, the lower end of the spacer and the form plate can be coupled to each other in the form of a hook, so that the joining and disassembling work can be easily performed.

In addition, through this, the productivity can be improved by reducing the number of processes.

Also, since the form plate is not coupled with the bolt, after the completion of the construction, the form plate can be smoothly separated and the air can be further shortened.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings.

The deck plate A according to the present invention is characterized in that the truss girder T, the spacer S and the work plate P are butted against each other as shown in Figs. 1 to 4, A spacer S is coupled to the spacer S and a workpiece P is coupled to the lower end of the spacer S so as to face each other.

The truss girder T is embedded in the concrete C to be laid and supported by the tension force so that the truss girder T is supported on the upper end of the lattice material T2 having a diameter smaller than the diameter of the phase current T1 on both sides of the phase current T1. And the bottom end of the lattice material T2 is brought into contact with the bottom end T3 of the bottom of the lattice material T2 to be welded and joined together. At this time, it is preferable that the lower end of the lattice material T2 is expanded.

The spacer S is formed such that the truss girder T is completely embedded into the concrete C placed so that the lower end of the truss girder T and the formwork P are kept at a predetermined distance. And a spacer body 20 is formed in a lower portion of the connecting rod 10 formed in a longitudinal direction. A plurality of the spacer bodies 20 may be provided depending on the load.

The reinforcing bending piece 101 is formed on both sides of the lower portion bent in the mountain shape to prevent the lower portion of the connecting rod 10 from being deformed. The connecting rod 10 is made of metal and can be welded to the truss girder T.

The spacer body 20 is formed integrally with the elastic part 220 of the lower part of the body part 210 so that the center of the elastic part 220 is formed in the engagement hole H formed in the formwork P Which is simply pressurized.

The elastic engaging part 220 is formed such that the hook piece 222 extends outward at the lower end of the engaging piece 221 formed to stand upright below the body part 210.

The engaging piece 221 and the hook piece 222 are formed with a cutout space portion 223 having a predetermined distance therebetween so as to apply an elastic force to the engaging piece 221.

The latching hole H is formed in the form plate P so as to correspond to the resilient latching part 12 of the spacer S so that the coupling can be easily performed.

Meanwhile, in the present invention, the body portion 210 of the spacer body 20 has a cylindrical shape, but it is preferable that the body portion 210 has a polygonal shape in addition to this shape.

The cutout space 223 is formed to have one of a straight shape, a wedge shape and a cross shape so that when the center of the elastic fastening part 220 is pressed against the fastening hole H of the formwork P, The outer periphery of the engaging piece 221 comes into contact with the inner edge of the engaging hole H and is separated in the opposite direction as the inserting is completed .

Such a deformation-type deck plate A first aligns the center of the body portion 210 of the spacer body 20 provided on both sides of the spacer S with the center of the engagement hole H formed in the formwork P . At this time, when the connecting rod 10 is pressed downward in a state where the center of the elastic catching portion 220 formed upright to the lower portion of the body 210 is aligned with the catching hole H of the formwork P The pressing force and the inclination of the hook piece 222 cause the inside of the cutout space portion 223 to be misplaced.

The edge of the hook piece 222 passes through the latch hole H and the state where the cutout space 223 is widened by the elastic force of the latch piece 221 is restored to the initial state and the latch piece 221 Is engaged with the inner periphery of the latching hole H while being abutted against each other.

Next, the deck plate A is obtained by fixing the lower end T3 of the truss girder T to the upper part of the connecting rod 10 of the spacer S, and connecting the butted portion with the welded joint .

Meanwhile, after the deck plate A obtained through the above process is installed and the concrete C is cured and cured, the edge of the hook piece 222 is deformed while being pulled out of the lower part of the form plate P do.
