[Detailed description of the device]

[0001]

[Industrial application]

 This invention is a support tool for supporting a separator mounted on a wall formwork at a desired interval on a slab formwork in construction of a wall formwork, etc., especially for mounting and fixing the support tool when dismantling the formwork. The nails that are driven into the slab formwork come out together with the formwork when the slab formwork is dismantled, and relate to a separator support that does not require post-treatment of the nails after disassembly.

[0002]

[Prior Art]

 Conventionally, the support that is mounted on the slab formwork to support the separator is composed of a support body that has a nut part that supports the screw part of the separator by screwing in and a tubular part that is used to fix the slab formwork to a nail. However, the tubular portion is formed in a double structure of the inner tubular portion and the outer tubular portion, the inner tubular portion and the outer tubular portion have substantially the same height, and the outer circumference of the inner tubular portion and the inner circumference of the outer tubular portion are Disclosed is a support tool which is integrally formed by joining a part of each of the side surfaces.

[Problems to be solved by the device]

 According to the above-mentioned conventional method, as shown in FIG. 5, when the mold is dismantled, the nail A inserted into the nail insertion hole 13b of the inner tubular portion 13 and driven into the slab mold C is removed from the slab mold C. The joint 16 breaks due to the force in the substantially vertical direction when the slab form C is detached, but in the actual construction situation, the slab form is disassembled from the concrete skeleton by a tool such as a burl. It is peeled off diagonally downward and the inner cylinder part where the nail is inserted is pulled in almost the same direction as the slab form, so that the joint is less likely to break. Therefore, the inner cylinder and the nails inserted in the inner cylinder are left without being separated from the outer cylinder, and the worker must remove the nails as a post-treatment, resulting in poor workability and certainty. There are problems such as poor supply.

[0004]

[Means for Solving the Problems] The present invention has been made in view of the above-described conventional problems, and an object thereof is to reliably support a separator that supports a mold and to ensure that a joint portion is securely formed when the mold is dismantled. It is intended to provide a support tool for a construction separator which is ruptured and the inner cylinder and the nail inserted into the inner cylinder come out of the outer cylinder and can be easily removed together with the formwork.

As a means for this, in a support for a separator in which a tubular portion for nail insertion has a double structure, a fitting portion is provided on the outer periphery of the inner tubular portion and a projecting portion is provided on the inner periphery of the outer tubular portion. In addition, it is characterized in that one end of the lower surface of the fitting portion and one end of the upper surface of the protruding portion are joined together by an appropriate thin-walled joining portion to be integrally formed.

With the above structure, a fitting portion is provided around the outer circumference of the inner cylindrical portion, and a protruding portion is provided around the inner circumference of the outer cylindrical portion, and one end of the lower surface of the fitting portion and one end of the upper surface of the protruding portion are appropriately arranged. Since the thin-walled joints are joined together, the inner tubular portion is integrally formed with a shape projecting upward from the outer tubular portion. Therefore, when fixing the support of the separator on the slab form, the nail is driven along the nail insertion hole of the inner tube, but in that case, the inner tube protruding above the upper end of the outer tube is the nail. The inner cylinder moves downward until the lower surface of the inner cylinder contacts the upper surface of the slab form, and at the same time the joint between the fitting part of the inner cylinder and the protruding part of the outer cylinder breaks. Therefore, it can be easily removed together with the formwork when the formwork is disassembled. In addition, after the joint portion between the fitting portion of the inner tubular portion and the protruding portion of the outer tubular portion is broken, the fitting portion circumferentially provided on the inner tubular portion is fitted to the projecting portion circumferentially provided on the inner circumferential surface of the outer tubular portion. This is to solve the above-mentioned conventional problems such that the support body is prevented from being lifted up and firmly fixed to the mold when the concrete is set.

As shown in FIG. 3, the support 1 of the present invention is arranged at a desired position on the slab form C, and the nail A is inserted into the nail insertion hole 3b of the inner tubular part 2 to form the slab form C. The inner cylinder part 3 is driven and fixed, and at this time, the nail A is inserted into the nail insertion hole 3b of the inner cylinder part 3 as shown in FIG. Since it is driven downward until it becomes almost the same height as the upper end of the part 2, the joint part 6 breaks, and the protruding part 2a circumferentially provided below the inner circumference of the outer cylinder part 2 is attached to the inner circumference of the inner cylinder part 3. The fitting portion 3a provided around the fitting portion 3 is fitted with a proper frictional force. Next, one screw part of the separator B that supports the wall form is screwed into the nut 5 attached to substantially the center of the support body 1 along the insertion hole 4 of the separator to support the wall form. After that, when the slab formwork is stripped down when the formwork is dismantled, the nail A inserted into the inner tube portion 3 and the nail insertion hole 3b of the inner tube portion 3 comes out by dismantling the slab formwork C. ..

[Effect of the device]

 As described in detail above, according to the supporting device for the construction separator of the present invention, the fitting portion is provided on the outer circumference of the inner cylindrical portion, and the protruding portion is provided on the inner circumference of the outer cylindrical portion. Since the one end of the lower surface and the one end of the upper surface of the projecting portion are joined by an appropriate thin-walled joining portion, the inner tubular portion is integrally formed in a state of projecting upward from the outer tubular portion. Therefore, when fixing the support of the separator to the formwork, the nail is driven along the insertion hole of the nail of the inner cylinder, but in that case, the inner cylinder protruding upward from the upper end of the outer cylinder is the nail. Since they are driven together, the inner cylinder moves downward until the lower surface of the inner cylinder contacts the upper surface of the slab formwork, and at the same time the joint between the fitting part of the inner cylinder and the protruding part of the outer cylinder breaks. Since the slab formwork can be easily removed together with the formwork at the time of dismantling, reliable construction can be performed without the need for twice, and work efficiency can be improved. Also, after the joint between the fitting part of the inner cylinder part and the protruding part of the outer cylinder part is broken, the fitting part circumscribing the outer circumference of the inner cylinder part has an adequate friction against the protruding part circumscribing the inner circumference of the outer cylinder part. Since the mating state is achieved with force, the support body is prevented from rising during concrete pouring and is firmly fixed to the formwork, so it is also reliable in terms of strength, and reliable work can proceed. A support for a construction separator that is practically useful can be obtained.
