Abstract

(57) [Abstract] [Purpose] In the beam main bar bracket of the basic rebar assembling equipment that promotes the construction of beam rebars, while suppressing the occurrence of cross-section loss during concrete placement, the installation of the kanzashi bar is simple and We provide a beam main bracing bracket with good bar accuracy and low cost. [Structure] Both ends of a flat plate-like main body are bent upward to form support pieces, and through holes are formed in the support pieces.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a main reinforcing bar bracket of a basic reinforcing bar assembling apparatus that supports the upper beam main bar from the lower side and arranges it at appropriate intervals along the longitudinal direction in constructing the basic rebar to facilitate the assembly of beam rebars. .

[0002]

[Prior art]

 Conventionally, as shown in FIG. 5, the beam main bar receiving bracket of the basic rebar assembling apparatus has been constructed by cutting a square pipe into an appropriate length and fixing it by welding or the like in a state orthogonal to the upper column. As a method of mounting, firstly, a knitting bar for receiving the main beam of the beam was inserted into the square pipe, and then a female screw portion provided on the bottom surface of the square pipe was fastened with a bolt capable of moving up and down. .

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional method, since a square pipe is used to receive the main beam of the beam, if concrete is not filled in the gap between the square pipe and the kanzashi streak inserted in the square pipe, that part becomes hollow and the cross-section is damaged. This is easy to cause, and since the height of the square pipe and the height of the doublet are different by the thickness of the pipe, a step is generated in the beam main bar and the bar arrangement accuracy deteriorates. In order to fix the kanzashi muscle inserted in the square pipe, a female screw portion and a bolt attached to the female screw portion were required on the bottom surface of the square pipe, so the work of tightening the bolt was troublesome and the number of parts was small. There are problems such as high cost due to the large number.

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to suppress the occurrence of a cross-sectional defect of the beam main bar receiving bracket, eliminate the step of the beam main bar, and save labor in the work of attaching the knot bar. At the same time, the number of parts is reduced to provide a beam main bar support bracket for a basic rebar assembling device that is easy to cost.

The means is characterized in that both ends of the flat plate-shaped main body are bent upward to form support pieces, and through holes are formed in the support pieces.

[0006] With the above structure, since the kanzashi streak is inserted into the through hole of the support piece formed by bending both ends of the flat plate-shaped main body upward, there is no gap where concrete is not filled and the cross-section is lost. Can be suppressed. Since the main beam of the beam is placed only on the kanzashi line inserted in the through hole, no step is formed. In addition, since the attachment of the knitting strips is inserted continuously into the through holes of the two support pieces, the time and effort required for tightening with bolts are eliminated, the number of parts can be reduced, and the cost can be reduced. The conventional problems are solved.

It is a perspective view showing a basic rebar assembly device. Reference numeral 10 is a beam main metal bracket of the present invention, 1 is a main body made of a flat steel plate, and 2 is a support piece in which both ends of the main body 1 are bent upward at a substantially right angle. Numerals 3 and 3 are through holes which are bored substantially at the centers of the support pieces 2 and 2 and into which the knot muscles are inserted, and are provided coaxially. Further, reinforcing ribs 4 may be provided at appropriate places along the main body 1. Reference numeral 20 is a basic reinforcing bar assembling apparatus, 5 is an upper strut, 6 is a lower strut, 7 is a pedestal, and 8 is a tightening bolt. The upper end surface of the upper column 5 and the substantially center of the main body 1 are fixed by welding.

FIG. 4 is a use state diagram of the embodiment of the present invention, in which the through holes 3 formed in the supporting pieces 2 and 2 of the beam main bar receiving metal fitting 10 fixed to the upper column 5 of the basic reinforcing bar assembling apparatus 20. Insert kanzashi muscle A cut into a suitable length in 3. In this case, for example, even if the outer diameter of the knitted muscle A is slightly smaller than the diameter of the through holes 3 and 3, the knitted muscle A can be firmly held by bending the support pieces 2 and 2 inward. It is necessary to arrange the basic rebar assembling devices 20 to which the knitting bar A is attached at appropriate intervals along the position where the girder bar is constructed, and to sequentially place the beam main bar B on the knitting bar A at a predetermined interval. For example, tie it with a wire C and fix it.

[Effect of device]

 As described in detail above, according to the beam main bar receiving bracket of the basic rebar assembling device of the present invention, the knotted bar is formed in the through hole of the support piece formed by bending both ends of the flat plate-shaped body upward. Since there is no gap where concrete is not filled because it is inserted and attached, it is possible to suppress cross-section defects and obtain structural reliability. Since the main beam of the beam is placed only on the kanzashi line inserted in the through hole, there is no step, and the beam line can be constructed with higher accuracy of the bar arrangement. Also, since the attachment of the knitting strips is continuously inserted into the through holes of the two support pieces, the work of fastening with bolts is eliminated, labor can be saved, the number of parts can be reduced, and the cost is reduced. Therefore, it is possible to obtain a beam main bar receiving metal fitting of a basic rebar assembling device that is practically useful because it is very economically advantageous.
