Abstract

(57) [Summary] (with modifications) [Purpose] To provide a reinforcing bar spacing adjustment jig that can accurately ensure butting spacing between reinforcing bars and improve workability. [Structure] A jig that keeps the spacing between the butt ends of reinforcing bars constant, and is equal to the spacing between the saddle plate 2 that can be placed on the reinforcing bars and the reinforcing bars connected at one end of the saddle plate 2 in the perpendicular direction of the saddle plate. It consists of a thick backing plate 3. [Effect] A predetermined spacing between reinforcing bars can be secured by simply touching the reinforcing bars to be connected to the contact plate of the reinforcing bar spacing adjustment jig.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention allows you to adjust the spacing between reinforcing bars at a constant level when placing a large number of reinforcing bars abutting each other. This relates to a reinforcing bar spacing adjustment jig.

0002

[Conventional technology]

When connecting reinforcing bars by enclosure welding, the required 10 mm before welding between the reinforcing bars It is necessary to provide a later interval. Adjustment of reinforcing bar spacing is done after or at the same time as reinforcement work. Ru.

0003

[Problem that the invention attempts to solve]

The conventional reinforcing bar connection technology described above has the following problems. <B> Since the spacing of reinforcing bars has a large effect on the joint strength of welding, it must be determined with a certain degree of accuracy. is required. Therefore, if adjustments are made while measuring using a measuring tool, work efficiency will be significantly reduced. In particular, when joining long deformed reinforcing bars that are heavy and difficult to slip, it is more difficult to adjust the spacing. It becomes difficult. <B> If the operator's intuition is relied upon to adjust the spacing, variations in the spacing are likely to occur. <C> When welding multiple reinforcing bars on the same line, if the spacing in one place is incorrect, , This correction requires readjustment of other abutting parts. <D> For these reasons, conventionally there were variations in the adjustment of the specified spacing of reinforcing bars. Irregular spacing between reinforcing bars is a cause of welding defects.

0004

[Purpose of this invention]

This invention was devised in view of the above points, and its purpose is to We offer a reinforcing bar spacing adjustment jig that can maintain accurate spacing and improve work efficiency. It is about providing.

[0005]

[Means to solve the problem]

The present invention is a jig that keeps the spacing between the butt ends of reinforcing bars constant, and is placed on the reinforcing bars. Equal to the distance between the possible saddle plates and the reinforcing bars connected at one end of the saddle plate in the direction perpendicular to the saddle plate. It is a reinforcing bar adjustment jig consisting of a thick backing plate.

[0006]

[Configuration of the present invention]

The present invention will be described below with reference to the drawings. <A> Rebar spacing adjustment jig FIG. 1 shows an example of a reinforcing bar adjustment jig 1 according to the present invention. The reinforcing bar adjustment jig 1 includes a saddle plate 2 having a chevron-shaped cross section, and one end of the saddle plate 2 that is perpendicular to the saddle plate 2. It consists of a backing plate 3 that is connected towards the target, and the material is not particularly limited, such as steel or resin. . <B> Saddle board The saddle plate 2 is a plate material placed on top of the reinforcing bars 5, and is open on the inside. If a handle 4 is attached to the upper part of the saddle plate 2, handling is convenient. ＜C＞Touching board The backing plate 3 has a gauge function to ensure the spacing between the reinforcing bars 5 and makes it easy to butt the reinforcing bars 5 together. It is a plate material that has an area larger than the cross section of the reinforcing bar and has the function of The plate thickness T of the backing plate 3 is set to be approximately equal to the interval C between the ends of the reinforcing bars 5 to be secured. . In addition, when fixing one side of the backing plate 3 to the saddle plate 2, the opening of the saddle plate 2 is completely covered with the backing plate 3. If it is completely sealed off, it will be difficult to determine the position of the reinforcing bars within the saddle plate 2. Therefore, the reinforcing bars inside the saddle plate 2 are visible between the top of the saddle plate 2 and the upper edge of the cover plate 3. A viewing window 6 is formed in advance. The viewing window 6 may be formed in the form of a slit in the plate surface of the cover plate 3 or the saddle plate 2.

[Effect]

Next, the method of arranging reinforcing bars will be explained. <A> Set of jig First, one reinforcing bar 5a is laid, and the reinforcing bar adjustment jig 1 is placed over the end of the reinforcing bar 5a. Ru. At this time, the contact plate 3 is brought into contact with the end face of the reinforcing bar 5a, and the reinforcing bar adjustment jig is inserted through the saddle plate 2. 1 is placed on top of the reinforcing bar 5a. <B> Butt of connecting reinforcing bars Next, the ends of the reinforcing bars 5b to be connected are brought into contact with the contact plate 3, and the reinforcing bars are arranged. The present invention simply connects the reinforcing bars 5b to the plate 3 without using measuring tools or relying on intuition as in the past. By simply pressing the reinforcing bars 5a and 5b lightly, the thickness T of the backing plate 3 is applied to the ends of both reinforcing bars 5a and 5b. It is possible to secure the following distance. Either leave the reinforcing bar adjustment jig 1 until just before welding, or remove it and adjust the next reinforcing bar 5. used for. Preferably, a plurality of reinforcing bar adjustment jigs 1 are prepared in advance. <C> Welding After removing the reinforcing bar adjustment jig 1, weld the butt points of the reinforcing bars 5a and 5b. Ru.

[0008]

[Effect of the idea]

Since the present invention is as described above, the following effects can be obtained. <B> After placing the reinforcing bar adjustment jig on the reinforcing bars, place the reinforcing bars to be connected on the backing plate of the reinforcing bar adjustment jig. It is a simple task of just touching the reinforcing bars to ensure the specified spacing between the butts. This allows you to perform reinforcement work without having to worry about troublesome spacing adjustments. Therefore, work efficiency is significantly improved compared to the conventional method. <B> The work does not have to be done by adjusting the spacing using measuring tools or relying on the intuition of the worker. This eliminates the need for accurate and consistent spacing. As a result, the incidence of welding defects is reduced. <C> Even if the reinforcing bar cross section is small in diameter, the reinforcement plate is larger than the reinforcing bar cross section, so You can easily perform alignment work. <D> The internal reinforcing bars can be seen through the viewing window of the reinforcing bar adjustment jig that is placed over the reinforcing bars. It is easy to achieve linearity.
