BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a deformation-type decking spacer and a deformation-type deck, and more particularly, to a deformation-type deformation spacer and deformation-type deck provided between a truss girder and a decking deck.

In the use of metal form deck in the floor or underground floor construction of buildings in apartment buildings, office buildings, multi-use facilities, demolition of formwork boards of steel or plywood for the purpose of construction, use cracking or maintenance caused by external force The decking deck is used to carry out the bottom plate construction and the spacers are used to facilitate the demolding of the formwork in the decking deck and to maintain the sheath thickness of the truss girder.

Also, after the deformation of the formwork board, the spacer for de-molding deck is embedded in the lower part of the slab of the concrete structure, so that ducts and ceiling finishing materials for air conditioning or electric wiring can be easily installed.

However, the conventional spacer has another problem in that, when the vertical load of the duct and the ceiling finishing material installed at the lower portion is increased, the insert is pulled out to collapse the duct and the ceiling finishing material.

As a background of the present invention, there is a patent registration No. 1237323 entitled "Spacer for Deformable Deck" (Patent Document 1). 11A, a spacer A is provided between a truss girder and a steel plate. In the spacer A, a synthetic resin spacer body 10 formed of two hexahedrons is made of a steel material And the spacer head 20 is formed by insert injection molding so as to be coupled to both longitudinal ends of the spacer head 20 formed by the spacer head 20. The spacer body 10 is formed with a downwardly directed female screw 11, Wherein a head piece (21) is formed in a longitudinal direction by being narrowed to be narrowed from a lower part to an upper part, and a reinforcing piece (22) is bent obliquely to the upper side of the outer side at the lower end of the head piece (21) Quot; spacer. &Quot;

However, in the background art, it is not easy to bond the spacer body 10 and the spacer head 20, which are heterogeneous materials, and the spacer head 20 embedded in the spacer body 10 is embedded only at the lower end, There is a problem that the spacer head 20 is deformed or pulled out of the spacer body 10 when the vertical load of the spacer body 20 is increased.

11B, the spacer head 20 coupled to the spacer body 10 has a reinforcing piece 22 that is bent obliquely upwardly from the outside of the lower part of the head piece 21 in the shape of Λ, The work load acting on the deformation type deck acts locally as a pulling force between the deformation-type deck spacer A and the truss girder, so that the reinforcing pieces 22 perform the pull-out resistance behavior in the spacer body 10. At this time, a pressing stress such as expansion (expansion) occurs between the reinforcing piece 22 and the spacer body 10, so that the spacer body 10 can not move due to the engaging action and resists the pulling force by pure tension resistance. There is a problem in that it is not effective in pulling force because the reinforcing piece 22 is additionally formed at the end without separately providing the piece 21. [

A wedge 13 having the same cross section as the inner end surface of the fixing portion 113 is formed in the fixing portion 113 of the transverse bridge engaging member 11 so that the fixing portion 113 is fixed to the supporting block 12 So that the wedge connection is made without releasing.

The wedge 13 may be formed at both ends of the fixed portion 113 of the transverse bridge engagement member 11 or may be formed over the entire fixed portion 113. [

The wedge 13 is formed to have the same cross section as that of the inner surface of the fixing portion 113 so that the fixing portion 113 can be fitted into the fixing portion 113. When the supporting block 12 is manufactured, The wedge 13 may be filled in the fixing part 113 to be integrally formed with the supporting block 12. [

4b, in the construction step, the truss girder 20 and the transverse bridge joining member 11 are connected to each other by a construction load (worker, concrete installation weight, etc.) acting on the form board 30. [ The recessed portion 111 of the central recessed portion is formed to be engaged with the support block 12 and then the wedge 13 is used to achieve the meshing action, (10) and the ceiling finishing material (10) after the completion of the completion of the de-molding deck spacer (10) The spacer 10 for de-molding deck is not pulled out even when the load is increased.

The second supporting member 15 thus formed is fitted in the fitting groove 112 of the transverse bridge engaging member 11 so that the fitting groove 153 is engaged.

Since the cross section of the engaging section 112 has a concave section at the lower end, the lower end of the engaging groove 153 is formed to be narrower at the lower end and the upper end thereof is wider, The second supporting member 15 is pressed by the upper portion of the engaging portion 112 to be engaged with the second supporting member 153.

When the second supporting member 15 is engaged with the engaging portion 12, the slanting portion 152 can be opened or closed to adjust the overall height of the second supporting member 15. [

In this case, although the entrance of the fitting groove 153 is narrow, the engaging portion 112 does not separate from the engaging portion 112, but the engaging portion 112 may be further welded to the engaging portion 112 by welding.
