A wall corner aluminum formwork back support structure

Abstract

This application discloses a back support structure for aluminum formwork at a wall corner, comprising: aluminum formwork A and aluminum formwork B supporting the corner of the wall, both aluminum formwork A and aluminum formwork B being vertically installed perpendicular to each other; and a C-shaped steel plate installed on the back of the contact point between aluminum formwork A and aluminum formwork B. When concrete is poured into the wall, the corner of the wall is supported by aluminum formwork A and aluminum formwork B, and the back of the contact point between aluminum formwork A and aluminum formwork B is supported by the surface contact of the C-shaped steel plate. This allows the C-shaped steel plate to uniformly and stably support the back of the vertically distributed ends of aluminum formwork A and aluminum formwork B, solving the problem that horizontal diagonal bracing points supporting the back of the formwork on both sides cannot uniformly and stably support the back of the two vertically distributed formwork ends.

Description

Technical Field

[0001] This utility model relates to a back support structure for aluminum formwork at wall corners, belonging to the field of aluminum formwork technology. Background Technology

[0002] Before pouring concrete into a wall with corners, aluminum formwork must be vertically installed at the corners to create the pouring space.

[0003] The existing corner aluminum formwork installation technology, as seen in Chinese Patent Publication No. CN112459465B, uses multiple vertically distributed adjustable struts to reinforce the back of the two formwork panels at the corner. However, the multiple horizontal struts only provide point support to the back of the two formwork panels and cannot provide uniform and stable back support to the ends of the two vertically distributed formwork panels. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a back support structure for aluminum formwork at wall corners.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a back support structure for aluminum formwork at wall corners, comprising:

[0007] Aluminum formwork A and aluminum formwork B are used to support the corner of the wall. Both aluminum formwork A and aluminum formwork B are installed vertically and perpendicular to each other.

[0008] It also includes a C-shaped steel plate installed on the back of the contact point between aluminum mold A and aluminum mold B.

[0009] The aluminum mold A has a back rib A on its back, the end of which abuts against a C-shaped steel plate, and a through bolt assembly A passes through the aluminum mold A to press the back rib A.

[0010] The back rib A and the through bolt assembly A are multiple sets distributed vertically at intervals.

[0011] The C-shaped steel plate at the back of aluminum mold B has a back rib B, and the aluminum mold B and the C-shaped steel plate are connected by a through bolt assembly B, which presses the C-shaped steel plate tightly against the back of aluminum mold B.

[0012] The back rib B and the through bolt assembly B are multiple sets distributed vertically at intervals.

[0013] It also includes horizontal diagonal braces at both ends that support and resist aluminum mold A and aluminum mold B, with the middle of the horizontal diagonal braces contacting the C-shaped steel plate.

[0014] The horizontal bracing consists of multiple vertically staggered cross bracings that abut against aluminum mold A and aluminum mold B. The horizontal projections of these multiple vertically staggered cross bracings do not overlap.

[0015] The beneficial effects of this utility model are as follows: when concrete is used to pour the wall, the corner at the inside corner of the wall is supported by aluminum mold A and aluminum mold B. The back of the contact point between aluminum mold A and aluminum mold B is supported by the surface of C-shaped steel plate, so that the C-shaped steel plate can evenly and stably support the back of the vertically distributed aluminum mold A and aluminum mold B, solving the problem that the horizontal diagonal bracing points supporting the back of the templates on both sides cannot evenly and stably support the back of the two vertically distributed templates.

[0019] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0020] like Figures 1 to 2 As shown.

[0021] This application discloses a back support structure for aluminum formwork at a wall corner, comprising:

[0022] Aluminum molds A1 and B2 are installed vertically and perpendicular to each other. Aluminum molds A1 and B2 support the corners at the inside corners of wall 3. There are two aluminum molds A1, which are distributed opposite each other on both longitudinal sides of wall 3, and two aluminum molds B2, which are distributed opposite each other on both transverse sides of wall 3. Aluminum molds A1 and B2 at the outside corners of wall 3 are not shown in the figure.

[0023] It also includes a C-shaped steel plate 4 installed on the back of the contact point between aluminum mold A1 and aluminum mold B2; the back of aluminum mold A1 has a back rib A11, the end of the back rib A11 abuts against the C-shaped steel plate 4, and a through bolt assembly A12 passes through aluminum mold A1 to press the back rib A11. The back rib A11 and the through bolt assembly A12 are multiple sets distributed vertically at intervals.

[0024] When concrete is used to pour the wall 3, the corner of the wall 3 is supported by aluminum formwork A1 and aluminum formwork B2. The back of the contact point between aluminum formwork A1 and aluminum formwork B2 is supported by the back C-shaped steel plate 4, so that the C-shaped steel plate 4 can evenly and stably support the back of the vertically distributed aluminum formwork A1 and aluminum formwork B2, solving the problem that the horizontal diagonal bracing points supporting the back of the two templates on both sides cannot evenly support the back of the two vertically distributed templates.

[0025] The C-shaped steel plate 4 at the back of the aluminum mold B2 has a back rib B21. The aluminum mold B2 and the C-shaped steel plate 4 are connected by a through bolt assembly B22. The through bolt assembly B22 presses the C-shaped steel plate 4 to the back of the aluminum mold B2. The back rib B21 and the through bolt assembly B22 are multiple sets that are vertically spaced.

[0026] It also includes horizontal diagonal braces 5 that abut against aluminum molds A1 and B2 at both ends, with the middle of the horizontal diagonal braces 5 contacting the C-shaped steel plate 4. The horizontal diagonal braces 5 are vertically staggered and cross each other, abutting against aluminum molds A1 and B2, so that the horizontal projections of the vertically staggered and cross-braces 5 do not coincide. Figure 2 As shown. The vertically staggered and intersecting horizontal braces 5 can apply a limiting force to the C-shaped steel plate 4 in the middle. When the horizontal braces 5 are compressed by the loads of aluminum molds A1 and B2, the force that causes pre-deformation in the middle of the horizontal braces 5 is transmitted to the C-shaped steel plate 4 and dispersed.
