Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a level adjustment jig for a perforated panel that is arranged upright.

[0002]

[Prior Art]

 Conventionally, when assembling a concrete wall driving form, prior to the assembling, root-wrapping mortar is raised at the foot of the form and the driving form panel is erected on it.

[0003]

[Problems to be solved by the device]

 However, this case has the following drawbacks. Nemaki mortar does not allow fine adjustment of the panel level, and if multiple panels are arranged, they will be uneven and will look very bad. Nemaki mortar is a ruler, and it requires considerable precision, so it takes time and time to raise it, and it requires skilled workers, which causes troubles in construction due to lack of manpower. There is. Not only does it take a long time to build up the Nemaki mortar, but the panel can only be built in earnest after the heaped Nemaki mortar has hardened, which increases the construction period. After the concrete is placed, it is necessary to clean the root-wrapping mortar, which is very troublesome. 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-mentioned object, the present invention raises a screw rod 2 which is inserted from a base 1 into a vertical hole 11 of a perforated panel B, and raises and lowers a bracket 3 which receives the lower surface of the perforated panel B. It is characterized by being screwed freely.

[0005]

[Action]

 Because of the above configuration, in use, the height of the receiving object 3 of the level adjusting jig A is adjusted to some extent in advance, and the base 1 is installed at a predetermined position and the perforated panel B is installed. The vertical hole 11 is fitted to the screw rod 2, the lower surface of the holed panel B is placed on the receiving metal 3, and the receiving metal 3 is screwed as necessary to adjust the level appropriately. Further, the gap at the lower end of the perforated panel B is closed with a shackle C, and required supporting work is performed to properly assemble the formwork. After that, concrete D is placed inside the perforated panel B, and after a predetermined strength is exhibited in the concrete, a part or all of the formwork is appropriately dismantled and removed. That is, when the perforated panel B is used as a driving form, the perforated panel B and the level adjusting jig A are left and the other parts are dismantled and removed, and the perforated panel B is used as a transfer form. In some cases, it may be dismantled and removed as a whole.

[0006]

【Example】

 The drawings show embodiments of the invention. In the figure, A is a level adjusting jig according to the present invention, B is a perforated panel built using the level adjusting jig, C is a pier with a gap below the perforated panel closed, and D Is a concrete placed inside the perforated panel and the pier. The level adjusting jig A is provided with a base 1 made of a hexagonal steel plate having a width that fits within the thickness range of the perforated panel B, and an appropriate length to be inserted from the base 1 into the vertical hole 11 of the perforated panel B. A hexagonal nut-shaped receiver 3 for receiving the lower surface of the perforated panel B is screwed to the screw rod 2 so as to be vertically adjustable. A plate nut may be used for the base 1. The perforated panel B forms a driving mold, and by being driven and integrated into the surface of the casting concrete also as a surface material, the surface priming work or finishing work can be omitted and the removal work can be eliminated. The goal is to reduce the amount of waste wood as much as possible, reduce the amount of industrial waste that is a problem for disposal, and reduce the use of wood, which is a problem in the world's unregulated logging. Thus, the perforated panel B is an extruded cement board provided with pits 11 into which the screw rods 2 are fitted at both ends, and is provided with concave and convex ridges, etc., that are driven and joined to the inner surface. As a raw material, a mixture of a hydraulic inorganic binder, an inorganic or organic fiber, other aggregate and water is used, and the mixture is sent to an extruder and extruded at high pressure. Of course, the material is not limited to this, and other materials and forming means may be used.

With the above-described structure, the level adjusting jig A adjusts the height of the receiving object 3 to some extent in advance, and as shown in FIGS. The vertical holes 11 of the plurality of perforated panels B installed in a row are fitted into the screw rods 2, respectively, and the lower surface of each perforated panel B is placed on the receiving metal 3 respectively. And adjust the level appropriately by screwing each receiving object 3 as required, and further, the gaps at the lower ends of the perforated panels B are temporarily fixed with nails E respectively on the outside. Properly assemble the formwork by closing it with the pier C and performing the necessary support work. Then, concrete D is placed inside each perforated panel B, and after the concrete has developed a predetermined strength, the perforated panel B and the level adjusting jig A are left and the other parts are dismantled and removed.

[0008]

[Effect of the device]

 According to the present invention, the height of the receiving member 3 is adjusted to some extent in advance, and the receiving member 3 is installed at a predetermined position on the base 1, and the vertical hole 11 of the built-in perforated panel B is fitted to the screw rod 2. It can be placed on the receiving object 3, so that if necessary, the receiving object 3 can be screwed to adjust the level appropriately, and the gap at the lower end of the perforated panel B can be closed with the pier C. Therefore, fine level adjustment of the panel, which is impossible with the root-wrapping mortar, can be performed easily, easily, smoothly, quickly, and accurately without any hindrance, and the construction efficiency can be improved. Also, this allows a plurality of panels to be arranged in a good-looking manner without unevenness. It eliminates the need for neck roll mortar, which requires precision, labor, time, and skilled workers to raise the heap, thus reducing the inconvenience of lack of manpower. It does not require a waiting time for work as in the case of Nemaki mortar, and the construction period can be greatly shortened. No need to pick the root-wrapping mortar after the concrete is placed, so the picking work is not troublesome. The quality of the finished product can be improved and the cost can be reduced. It is effective and practically useful.
