Description

[Detailed explanation of the invention] [Purpose of the invention] Industrial application field...The invention is based on the above-mentioned front and back panels, in which panel formwork is erected and supported in parallel in a gap corresponding to the thickness of the concrete wall to be formed. This invention relates to a support for concrete pouring formwork for supporting front and back panel formworks in parallel at regular intervals when filling the panel formwork with concrete.

Conventional technology: Conventionally, in order to erect and support the panel formwork in parallel at regular intervals, pipes were formed by combining vertical and horizontal butter pipes on the outer surfaces of the panel formwork on each of the front and back sides. A frame body was formed, and form ties penetrating the front and back panel formworks were fixedly supported on the front and back pipe frame bodies.

The support of the front and back panel formwork by the above-mentioned pipe frame causes the parts other than the panel formwork to be recessed, and when the panel formwork is removed, the concrete wall surface becomes wavy and unsightly. It was hot. In addition, since a large number of Bata pipes are required, the cost of transporting the pipes and a vast pipe storage area are required.Also, the work of combining pipes to form a pipe frame requires a large number of people and time, which is time-consuming. It was also economically uneconomical.

Therefore, in recent years, a formwork support as shown in FIG. 6 has appeared. The support 1 is provided with a flange portion 3 continuous to the dome-shaped portion 2 and extending around the dome-shaped periphery, a form tie insertion hole 4 is formed at the top of the dome-shaped portion 2, and a dome around the insertion hole 4 is provided. A form tie adjustment tool insertion hole 5 is formed in the shaped portion 2, and as shown in FIG. 6a and 6b, and was supported and fixed at the support 1 and the back panel 6a by nuts and fixtures. In the above-mentioned support device, the form tie adjustment device insertion hole 5 is provided in the dome-shaped curved portion, so that the form tie adjustment device can be supported from the side perpendicular to the form tie 7 inserted into the form tie insertion hole 4. It is necessary to provide a form-tie adjuster insertion hole 5 with a considerably large diameter, and the larger this hole is, the weaker the strength of the support becomes. Furthermore, if the diameter of the form tie adjuster insertion hole 5 is made small in order to prevent weakening of the strength, the form tie adjuster is inserted obliquely to the longitudinal direction of the form tie 7, making it difficult to adjust. In addition, in the support 1, only the back surface of the flange portion 3 partially contacts the panel-shaped formwork 6a, so the contact area is small and the support portion is unstable when the form tie is tightened. Furthermore, when the supports are installed, it is not only aesthetically pleasing to have a large number of supports arranged in a straight line either horizontally or vertically, but also ensures the support of the panel formwork and improves the stability of the concrete. This allows for smooth pouring and a beautiful concrete wall surface, but in order to achieve this, the support tool 1 is required.
The work can be carried out most quickly and efficiently by attaching a batapipe in the vertical or horizontal direction and using this batapipe as a guide to adjust the position of the support 1 attached to each panel formwork. Because it is dome-shaped, it is unstable and nearly impossible to support a batapipe on its outer surface. Therefore, as shown in Fig. 7, the panel formwork 6
Although the support 1 is provided at the boundary 8 between a and 6a, arranging and attaching the support located outside the boundary 8 in a straight line requires considerable effort and time, and the work efficiency is not improved. It was empty.

Problems to be solved by the invention: Compared to the conventional case where a pipe-shaped formwork is supported by a pipe frame formed by assembling Bata pipes, the present invention uses far fewer Bata pipes and is easy to transport. Not only can you reduce the cost of pipe storage and labor costs by shortening labor and time, but also the finished concrete wall will not be wavy and will have a good appearance. Moreover, unlike the support shown in FIG. 6, it is possible to firmly support the butterpipe in the horizontal or vertical direction as required, and the support can not only be installed correctly and in a straight line quickly, but also Panels in narrow spaces can be installed without using a batapipe, and the support of the panel formwork by the support is ensured because it is supported by almost the entire surface of the seat plate provided on the support. The home tie can be adjusted by inserting the home tie adjuster inserted through the home tie adjuster insertion hole at right angles to the length of the home tie inside the support, making the work easier. The object of the present invention is to provide a support for a formwork for concrete pouring that is quick and yet robust.

〔effect〕

In the present invention, the casing has a flat top surface, and the side peripheral surface protrudes at right angles from the periphery to form a U-shaped longitudinal section. A pair of Batapipes supported by the Bata pipes are supported correctly parallel and stably, so that the supports can be installed in a correct alignment in the vertical or horizontal direction, which not only looks good but also allows the formwork to It is possible to perform smooth pouring when pouring concrete. In addition, since the side circumferential surface is formed perpendicular to the top surface, the form tie adjuster inserted through the form tie adjuster insertion hole formed on this side circumferential surface can be inserted at right angles to the longitudinal direction of the form tie. Not only is it convenient to grip and rotate the form tie, but the hole for inserting the form tie adjuster can be made as small as possible, making it easier to hold the support. Can be made robust.

In addition, when attaching the support of the present invention to the formwork, the back surface of the seat plate, which is the mounting surface, is in contact with the formwork over substantially the entire surface except for the form tie insertion hole, and the contact surface is shown in FIG. Compared to known supports that contact only through the back surface of the flange, it is much larger and provides more reliable support, and can evenly press and support the formwork to give a beautiful finish to the concrete wall surface. In addition, the seat plate extends into the housing, and the outer surface of the side circumferential surface of the housing and the upper surface of the flange portion of the seat plate are reinforced with ribs, so that the entire support is constructed to be robust. Even if the form tie adjuster insertion hole is formed to be large or formed at a plurality of locations, a still more robust support can be provided. Furthermore, the amount of pipes used can be reduced without causing the concrete wall surface to become wavy, unlike the conventional support using a pipe frame formed by combining pipes vertically and horizontally. Not only can labor and time be saved, but it can also be installed without using a butter pipe if necessary.
