Abstract

(57) [Summary] In a curing net clamp, four locking hooks 4 that are bent into a hook shape on the side surface are individually fixed vertically and horizontally. The locking hooks 4 are welded to the outer surfaces of the metal fitting body 1, respectively. A welding end 4C of a pair of locking hooks 4 arranged vertically is formed by bending a welding end 4C welded to the metal fitting body 1 through a bent portion 4B to form a locking end 4A shorter than the entire length of the welding end 4C. Metal fitting body 1 in a state where they are butted against each other
And fix it by welding. [Effect] Even if some failure occurs in up to 4 locking hooks, the remaining locking hooks can be used repeatedly as 3 type, 2 type, 1 type locking hooks. It will be possible.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a curing net clamp for fixing a curing net to a temporary scaffold or the like.

[0002]

[Prior art]

 Conventionally, as this type of clamp, clamps described in Japanese Examined Patent Publication No. 8-3276, Japanese Utility Model Publication No. 57-7724, and Japanese Utility Model Publication No. 6-54848 have been devised. The first clamp is provided with a movement adjusting means for vertically moving a hook to be locked on the curing net, and the hook is moved to stretch the curing net. In the second clamp, a pin hole is opened in the metal fitting body of the clamp, and the locking pin is forcibly fitted and fixed in the pin hole. In addition, the third clamp has a pair of holding metal fittings that bend one metal rod and are equipped with upper and lower stopper arms on the left and right, and lock a total of four ring-shaped metal fittings of the curing net to this holding metal fitting. To do.

[0003]

[Problems to be solved by the device]

 However, although the first clamp can use a pair of left and right hooks with one clamp, it is difficult to increase the number of hooks further by providing the movement adjusting means. is there. Therefore, even if the end of the curing net is fixed, the number of the clamps that can be connected by one clamp is limited to two.

Further, since the second clamp has the hook forcibly inserted into the pin hole opened in the metal fitting body, it has a structure vulnerable to a load in the rotation direction of the hook. As a result, even if the fitting portion of the hook is slightly loosened, the hook cannot be fixed and it becomes difficult to connect the curing net.

Further, the third clamp can lock four annular fittings at the same time on one clamp in the vertical and horizontal directions. However, since the upper and lower hooks are continuously formed by one metal rod, if one of the hooks fails and cannot be used, other hooks extended to this hook will also be formed. Inconvenience occurs. In other words, if one hook comes off due to some impact, the other hooks connected to it will also come off. However, this type of curing net clamp can be used even if at least one hook remains. It is also desirable that this type of clamp, which is also a consumable item, can be used as many times as possible before it becomes unusable.

Therefore, the present invention has been devised to solve the above-mentioned problems. Even if a maximum of four hooks have some trouble, three hooks can be The purpose is to provide a curing net clamp that can be used repeatedly as a hook of 2 types and 1 type.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the first means of the present invention is a curing net clamp in which a hook for locking a curing net is provided on a clamp fitting that is detachably connected to a pipe for temporary scaffolding. The four locking hooks, which are bent into a hook shape on the side, are fixed individually on the top, bottom, left, and right.

The clamp metal fitting of the second means has a structure in which a metal fitting body that abuts on one side surface of the pipe and a lid body that abuts on the other side surface of the pipe are tightened with a connecting bolt. The hooks are respectively welded to the outer surface of the metal fitting body, and the engaging ends of the engaging hooks arranged above and below face each other with a gap.

The locking hook of the third means is such that a locking end portion shorter than the entire length of the welding end portion is bent from the welding end portion to be welded to the metal fitting body via the bending portion, and the locking hooks are arranged vertically. Welding and fixing to the metal fitting body with the welded ends of the stop hooks butted against each other is a means to solve the problem.

According to the present invention, the life of the curing net clamp itself is extended by the four locking hooks provided separately.

[0011]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The clamp fitting used in the present invention is a fitting main body 1 that abuts on one side of a pipe P for temporary scaffolding, and a lid body 2 that abuts on the other side of the pipe P. It is configured to do.

Four locking hooks 4 are fixed to the outer surface of the metal fitting body 1 of the clamp fitting by welding (see FIG. 1). The locking hooks 4 are arranged on the upper, lower, left and right sides with respect to the outer surface of the metal fitting body 1. Then, the locking end portions 4A of the locking hooks 4 arranged above and below are faced to each other with a space.

The locking hook 4 includes a welding end portion 4C that is welded to the metal fitting body 1, a bending portion 4B that is bent and extended from the welding end portion 4C, and a locking end that is further bent and extended from the bending portion 4B. It is composed of a part 4A. The entire length of the locking end 4A that locks to the locking ring Q1 of the curing net Q is shorter than the total length of the welding end 4C that is welded to the metal fitting body 1. This is because when the welding ends 4C of the pair of vertically arranged locking hooks 4 are butted against each other and fixed to the metal fitting body 1, the locking ring Q1 is passed between the locking ends 4A. This is to provide a gap. As described above, when the welding ends 4C are welded in a state where they are butted against each other, the pair of locking hooks 4 can be simultaneously welded by one welding.

[0015]

[Effect of the invention]

 Since the present invention is configured as described above, the product life of the curing net clamp itself can be extended.

That is, according to claim 1, since the four locking hooks 4 are separately fixed to one clamp metal fitting, for example, one or two locking hooks 4 may have some trouble. Even if it can no longer be used, it is now possible to use it as a curing net clamp using the remaining locking hook 4.

According to the second aspect, the upper and lower curing nets Q and the left and right curing nets Q can be locked at the same time.

Further, according to the third aspect, efficient welding can be performed with a small amount of work, and even the four locking hooks 4 can be welded with two operations.

As described above, according to the present invention, even if some failure occurs in up to four hooks, the remaining hooks have various beneficial effects such that they can be repeatedly used. .
