Description

Technical Field [0001] The present invention relates to a truss girder rebar assembly using a truss girder and a deck deck using the truss girder rebar assembly,

[0001] The present invention relates to a truss girder close-up tool used for constructing a slab and a method of constructing a truss girder root and a deck deck, A truss girder root sheave which can distribute the compressive stress generated in the deck deck to the upper compression root of the truss girder root to prevent distortion of the member coming from side lateral load or eccentricity due to the laying load during construction, The present invention relates to a method of constructing a deck.

Generally, deck plates in buildings are made of steel to form a bottom plate between beams and beams. The deck plate is shaped so that it has a certain shape rather than being used flatly to increase the distance between the beam and the beam to increase the economic efficiency. These decks are called 'golf decks'. The thickness of the steel deck is 0.8 ~ 1.6mm, and it should support the concrete loading and the load during the construction.

On the other hand, the 'deck deck' applied when the span is 4 m or more has the problem that the deformation of the section due to the twist occurs together with the distortion of the member due to the formation of the open bone between the mountain surface and the mountain surface. Since the reinforcing bars (the upper compression roots and the lower reinforcing rods) are spaced apart by a distance from the surface of the bone and the mountain surface, these reinforcing bars can not be combined with the 'golf deck'. Therefore, In order to secure the position and the spacing.

Therefore, the deformation of the section due to torsion and the distortion of the member due to torsion occur simultaneously during construction. Therefore, there is a need for a combination technique of the steel bars and the deck deck.

As a background of the present invention, Korean Patent Registration No. 10-1008414 has proposed a method of manufacturing a reverse oak angle steel truss and a thin steel plate deck decking plate. In the case of the reverse osorean truss truss shown here, the nut is installed and the bolt is fastened to the nut at the lower plate side forming the lower part of the bone. In this case, the reverse osmosis tussle truss is fixed to the steel plate deck by means of bolts, but there is no means for catching the tie spacing, so that it can not resist side lateral loads generated from the sides of the deck depending on the concrete loading. It is difficult to prevent distortion of the member coming from the load eccentricity.

In addition, most of the mechanical concept is the tensile resistance element of the bottom of the reverse osmosis truss. Since the joint with the deck steel deck is located at the bottom of the deck, the distortion of the deck is inevitable, It is a real problem that we can not solve.

Korean Patent Registration No. 10-1008414

The lower leg muscles 21 and the pair of upper compression muscles 22a and 22b may be made of circular reinforcing bars or deformed reinforcing bars. The lower limb 21 is resistant to tension in the slab and a pair of upper compression roots 22a and 22b are installed to resist compression in the slab.

The spacing assembly 24 is designed to prevent the deformation and distortion of the decking deck 12 under construction from compressive stresses generated by joining the decking surface 12 of the deck deck 12 to the top compression surface of the truss girder near- (22a, 22b), and also functions to prevent eccentric twisting of the upper compression roots (22a, 22b). Also, the spacing assembly 24 replaces conventional spacers for obtaining coating thickness.
