The present invention relates to a reinforcing bar assembly for slab construction, and a fastening device for fixing the formwork and the ceiling panel, and more specifically, from the cured concrete slab as well as fixing the formwork installed to build the slab of the building It is easy to dismantle the formwork, and after dismantling the form of the ceiling panel fastening for easy installation on the lower part of the slab in the horizontal state in installing the ceiling panel.

In general, in order to build a slab during construction work, a pile of panel-like panels such as plywood or steel plate is piled up with vertical support pillars and yoke joists, and the upper and lower main reinforcing bars and the reinforcing bars are tied with a binding line, After fixing with concrete and curing the formwork inside the formwork, the formwork is removed from the slab.

As such, the conventional construction of fixing the formwork and placing the concrete after curing is removed requires a lot of manpower and time to install the formwork, and also requires a lot of time and manpower to remove the formwork after curing the concrete. have.

In general, in order to fix the ceiling panel to the ceiling slab, the lower part of the slab cured by placing concrete is fixed to form a plurality of rows horizontally or vertically with wood, forming a frame, and fixing the ceiling panel to the lower part. Maintaining a constant distance between the ceiling panel and the ceiling panel takes a lot of manpower to fix the ceiling panel to be horizontal, and there is a problem that the installation cost is increased, another method is a ceiling panel fixing member as a fixing nut and an adjustment bolt In order to fix the fixing nut to the slab, it is necessary to drill the slab and fix the fixing nut to the hole. Problems that require a lot of workforce Can.

The present invention is to solve the above-mentioned problems, to install the formwork by tightening the formwork with a fixed bolt to the pre-assembled rebar assembly in order to build the slab of the building, loosen the fixing bolt after curing, and easily remove the formwork, In the installation of the ceiling panel, which is the next process, there is a technical problem of providing a reinforcing assembly for slab construction and a fastening device for fixing the formwork and the ceiling panel with a fixing pin in order to easily fix the slab in a horizontal state.

In order to solve the technical problem as described above, the fastening assembly for fixing the reinforcing bar assembly and the formwork of the present invention with a fixing pin is formed in the upper surface of the mounting groove is fitted into the rebar, the screw shaft hole is formed in the center of the lower surface, Through-holes are formed on both side walls of the seating groove, and a fastening body having a reinforcing metal plate embedded therein; and a fixing pin fixed through the hole to fix the reinforcing bars inserted into the seating groove; Is screwed into the screw shaft hole of the fastening body, the other end is projected out of a predetermined length from the lower surface of the body, the fixing bolt formed with a male screw portion on the outer peripheral surface.

In addition, when the concrete is cured, the slab formwork is demolished, and in the binding hole for joining the ceiling panel to the cured concrete, a seating groove is formed in which the reinforcing bars are fitted to the upper surface, and a screw shaft hole is formed in the center of the lower surface in the axial direction. And fastening holes formed at both side walls of the seating groove, and having a reinforcing metal plate embedded therein; and a fixing pin fixed through the through hole to fix the reinforcing bars inserted into the seating groove; And a screw threaded to the screw shaft hole of the fastening body, and the other end of which is connected to the male screw so that the female screw can be coupled to the other end; and one end of which is formed to be connected to the other end of the connecting screw by a female screw part. And a supporting member having a flat surface perpendicular to the portion.

Here, the reinforcing metal plate is preferably made of a steel material, the through grooves are formed on both side walls facing each other, the bottom of the "凹" -shaped metal plate formed with a screw thread is formed is embedded into the interior of the fastening body.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

1 is an exploded perspective view of a fastener for fixing the reinforcing bar assembly and the formwork according to the present invention with a fixing pin, Figure 2 is a perspective view of a reinforcing metal plate embedded in the fastening body of the present invention, Figure 3 is a fastener according to the present invention This is a cross-sectional view of the state where the reinforcing bar is coupled to.

First, as shown in Figure 1, the binding sphere of the present invention as a means for joining the plate and the reinforcing bar of the formwork for concrete structures, it is possible to combine the plate forming the formwork and the reinforcing bar 40 is disposed in the plate The fastening body 10 and the fixing pin 20 and the fixing bolt 30 so as to be made large.

The fastening body 10 has a seating groove 1 in which the rebar 40 is fitted and seated on an upper surface thereof, and a screw shaft hole 3 is formed in an axial direction at the center of the lower surface thereof, and both side walls of the seating groove 1 are formed. The through hole 5-1 penetrates laterally. In addition, the reinforcing metal plate 7 may be embedded into the fastening body 10 to strengthen the strength of the fastening body 10.

Here, the reinforcing metal plate (7), as shown in Figures 2 to 3, the through grooves 5-2 are formed on both side walls facing each other, "凹" formed with a female screw portion 11 in the center of the lower surface It is preferable that the reinforcing metal plate 7 of the shape is embedded into the fastening body 10.

In addition, the fixing pin 20 prevents the reinforcing bar 40 fitted into the seating groove 1 of the fastening body 10 from being detached and securely fixes the through holes 5-1 and 5-2. It is fixed through.

The fixing bolt 30 is screwed into the screw shaft hole 3 of the fastening body 10 by penetrating the plate 100 to fix the plate 100 to the fastening body 10, and to an outer circumferential surface thereof. Has a male threaded portion (9).

Figure 4 is a cross-sectional view showing the construction state of the fastening assembly for fixing the reinforcing bar assembly and the formwork according to the present invention, the plate 100, which can trap the concrete 110 before curing, after the concrete 110 is cured Reinforcing bar 40 is assembled with the plate 100 so as to maintain the strength and the reinforcement assembly 130 for coupling the plate 100 and the reinforcing bar 40.

The formwork for the concrete 40 structure is inserted into the seating groove 1 of the fastening body 10, and then fixed with a fixing pin 20, and then through the plate 100 fastening body ( Assembly is completed by screwing the fixing bolt 30 to 10).
