Abstract

(57) [Summary] [Purpose] It is possible to easily, easily, smoothly and accurately perform fine level adjustment of a large-scale panel to be installed without any hindrance, and to improve construction efficiency. It allows large panels to be arranged in a non-uniform manner, eliminates the need for wedges, labor, and time-consuming root winding mortar, eliminates the waiting time for work, shortens the construction period, and eliminates the labor of picking work. [Structure] A flat plate receiving member 3 which erects a screw rod 2 from a base 1 and receives an appropriate flat plate B of a large panel A on the screw rod.
Is equipped with a vertically adjustable structure via a screwing means, the base 1 is set on a required concrete floor, and an appropriately laid flat panel B of the built-in large panel A is placed on the flat pedestal bracket 3. Then, the flattened receiving object 3 is moved up and down by the screwing means to adjust the level appropriately, and the gap at the lower end of the large-sized panel A is closed by the pier C.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a level adjusting jig for a large-sized panel that is erected and arranged as a concrete formwork.

[0002]

[Prior Art]

 Conventionally, when assembling a temporary concrete formwork such as a concrete wall body, since the concrete floor (land surface) is not level, a wedge or the like is placed between the concrete floor and the formwork, and a root-wrapping mortar is used. It fills the gap.

[0003]

[Problems to be solved by the device]

 However, this case has the following drawbacks. With the wedge, the level of the large panel cannot be finely adjusted, and when a plurality of large panels are arranged, they become unaligned and uncomfortable. Nemaki mortar is not easy to fill in the gap and takes time. Not only does it take time to pack the root wrap mortar, but the concrete can be placed in the formwork only after the root wrap mortar has hardened, which increases the construction period. After demolding, it takes a lot of trouble to clean the root mortar. There are still problems with the quality and cost of the finished product. The present invention seeks to solve these problems.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention raises a screw rod 2 from a base 1, and raises and lowers a flat plate support 3 for receiving a flat plate B of a large-sized panel A through the screw rod through a screwing means. The feature is that it is equipped to be adjustable.

[0005]

[Advantages] Due to the above-described configuration, in use, the base 1 is set on a required concrete floor, and the flattened receiving hardware 3 is adjusted up and down to an appropriate height by screwing means. Place the flatbed B of the large panel A that has been put in place on the flatbed receiving object 3 and, if necessary, further elevate the flattening receiving object 3 by screwing means to obtain an appropriate level. Adjust and then support to properly assemble the formwork. In addition, the gap at the lower end of the large panel A is closed by a shackle C. When using the pier C, the base 1 is arranged so as to be appropriately separated from the large-sized panel A, so that a sufficient space for use can be maintained and no trouble occurs. After that, concrete is placed inside the large-sized panel A, and after the concrete exhibits a predetermined strength, the formwork is dismantled and removed. At this time, the level adjusting jig and the pier C are also removed. The level adjustment jig after removal will be diverted to another.

[0006]

【Example】

 The drawings show embodiments of the invention. The level adjusting jig shown in the figure is provided with a steel base 1 having a bulged middle portion, and a screw rod 2 of a proper length made of a head bolt is erected from the base and laid flat on the screw rod. The hexagonal nut 4, which is the screwing means for receiving the lower surface of the receiving object 3, is screwed, and the flattening receiving object 3 is mounted on the hexagonal nut so that the hexagonal nut can be moved up and down. The flat-shaped receiving member 3 is formed by a steel plate in a U-shape in a plan view, and a U-shaped metallic member 31 is formed by a steel plate in a U-shape in a front shape so as to be brought into contact with the back surface of the horizontal plate B. A U-shaped metal fitting 32 adapted to receive the lower surface of the horizontal plate B is joined and integrated, and a through hole 33 is formed in the bottom of the U-shaped metal fitting 31 so that the screw rod 2 can be vertically moved. is doing. It should be noted that, in the case shown in the drawing, since the horizontal plate B is a round pipe, the upper surface of the U-shaped metal fitting 32 is formed into an arc surface conforming thereto.

Then, the base 1 is set on the required concrete floor, and the flattened bracket 3 is preliminarily screw-adjusted to an appropriate height, and the flattened flat bottom of the built-in large panel A is flattened. B is brought into contact with the entire surface of the U-shaped metal fitting 31 of the flat receiving metal fitting 3, is placed on the U-shaped metal fitting 32, and the hexagon nut 4 is screwed as required. Then, the horizontal receiving member 3 on the hexagon nut is appropriately moved up and down, and the large-sized panel A is appropriately adjusted in level. Then, the required support work is applied to the large-sized panel A to properly assemble the formwork, and the wood C is applied to the outside of the lower end of the large-sized panel A and fixed to the concrete floor with the nail D. Close the gap below. When dismantling and removing the formwork, both the level adjustment jig and the pier C are removed, and the level adjustment jig is diverted to another.

[0008]

[Effect of the device]

 According to the present invention, the height of the flat support 3 is adjusted to some extent in advance, and the base 1 is installed at a predetermined position, and the flat B of the built-in large panel A is flat. It is possible to place the flat support 3 on the screw rod 2 by the screwing means of the screw rod 2 so that the level can be adjusted appropriately, if necessary, and the large panel A can be used to adjust the level appropriately. Since they can be arranged apart from each other and the gap at the lower end of the large panel A can be closed by the shackle C, the wedge can be removed, and fine level adjustment of the large panel which is impossible with the wedge, It can be performed easily, easily, smoothly, smoothly, quickly, and accurately without any hindrance, and construction efficiency can be improved. Further, this makes it possible to properly arrange a plurality of large-sized panels without irregularity. Since the splint C can be used in place of the root winding mortar which requires troublesome packing, the work can be simplified and the inconvenience of lack of manpower can be reduced. The work time can be greatly shortened without the waiting time required when using Nemaki mortar. It eliminates the need for scavenging work of Nemaki mortar after demolding, thus eliminating the work of scavenging work. In addition, the jig can be diverted after the demolding. The quality of the finished product can be improved and the cost can be reduced. It is effective and practically useful.
