Abstract

(57) [Summary] [Purpose] Assembling of reinforcing bars can be done easily and securely without binding work, no skill is required, and working time is saved. [Structure] A right nut (10) and a left nut (11) are welded to the holding metal fitting (1) and the lifting metal fitting (2) by forming a burrow hole in the center of the wave. A pusher bolt (7) for vertically moving these metal fittings is formed by cutting a right-hand screw (8) and a left-hand screw (9) at both ends of an iron round bar. Insert a metal fitting combining these three members between the upper and lower end bars of the reinforcing beam and turn the presser bolt clockwise to make the holding metal fitting (1) push the lower end bar (3) downward and the lifting metal fitting (2). Since the upper end streak (4) is pressed upward to the stirrup streak, the beam can be reliably assembled.

[Problems to be Solved by the Invention] The binding work of all three members described in the prior art is a skill-consuming and time-consuming work. Because it is the work inside the beam formwork as shown in).

In particular, there has been a problem that the work of binding the lower end reinforcing bars (3) is difficult to the extent that it is practically impossible.

The present invention has been made in view of the above problems of the prior art. An object of the present invention is to press the upper end of the upper end streak and the lower end of the lower end streak to press the star lap streak. It is an object of the present invention to provide an assembly metal fitting capable of assembling a reinforced steel beam that is more reliable, quicker, and requires less skill than a reinforced steel beam assembled by bundling work by simply turning bolts.

[0006]

Means for Solving the Problems In order to achieve the above object, the assembly metal fitting according to the present invention is, in claim 1, an upper end piercing press formed by forming a fancy hole in a grooved steel web and welding a right nut. Lower end muscle presser that has a stupid hole in the metal of the lifting metal and the grooved steel web and welded the left nut, and the right screw is cut at one end of 100 mm and the left screw is cut at one end of 100 mm, and the nut is attached at the tip of the right screw. It is composed of three parts of bolts.

According to a second aspect of the present invention, there are two components, that is, a lower end bracing metal fitting in which a stiff hole is formed in a grooved steel web and a right nut is welded, and a full-thread bolt having a length of 100.

According to a third aspect of the present invention, there is provided a two-part configuration of an upper end bar support with an up-and-down motion adjusting mechanism made of equilateral mountain type steel, and a lower end bar presser attached to the lower side surface of the column.

[0009]

According to the first aspect of the present invention, the flange tip of the upper end bar pushing-up metal fitting is applied to the lower end of the upper end bar, and the flange tip of the lower end bar pressing metal fitting is applied to the upper end of the lower end bar to turn the pressing bolt clockwise. For example, the upper end bar is pushed up and the lower end bar is pushed down to the stirrup bar.

According to a second aspect of the present invention, the flange tip of the lower end bar pressing metal fitting is applied to the upper end of the lower end bar, and the tip of the pressing bolt is applied to the flange surface of the H-shaped steel and turned clockwise to weld it to the upper flange surface of the H-shaped steel. The upper rebars arranged on the pierced Kanzashi angle steel are pushed up and the lower rebars are pushed downward on the upper and lower surfaces of the stirrup bar, and the assembly of the steel-framed rebar beam is completed.

According to a third aspect of the present invention, the upper end stirrup is placed on the tip end of the flange of the light groove type steel for supporting the upper end streak of the main body with the vertical movement adjustment mechanism made of L-shaped steel, and the flange of the lower end streak retainer is attached to the upper end of the lower end streak When the tip end is applied and the pressure bolt is turned clockwise, the upper end bar is pushed up, the lower end bar is pushed down, and each is pressed by the stirrup bar, and the assembly of the underground beam bar is completed.

[Effect of the present invention]

 Since the present invention is configured as described above, it has the following effects.

In common with claims 1, 2, and 3, since the binding work is unnecessary, the skill required for the binding work is not required, so that even an unskilled person can perform the work, and the time required for assembly is reduced. Can be shortened.

In common with claims 1, 2 and 3, the assembly method has a limit in the assembly strength, and the assembly is in a sluggish state even after the assembly. You can hold the degree.

According to the first aspect of the present invention, the distance between the staples has recently been narrowed, and as a result, it is virtually impossible to bind the lower end streaks of a large beam. By adopting the present invention, the assembly can be done by simply tightening the bolts on the upper part of the beam, so that the lower end bar can be fixed and the conventional skilled work due to an unnatural posture is released. .
