Background

The building formwork is a temporary supporting structure, which is manufactured according to the design requirements, so that the concrete structure and the members are formed according to the specified positions and geometric dimensions, the correct positions of the concrete structure and the members are kept, and the self weight of the building formwork and the external load acting on the building formwork are borne. The template early-dismantling technology means that after concrete is poured, when the strength of a building body does not reach the formwork dismantling strength specified by construction specifications, part of templates and template supporting beams are dismantled in advance to accelerate the turnover use of the templates, so that one-time investment is reduced, the construction cost is reduced, and better economic benefit is obtained.

The existing building template comprises a template and a frame fixed on the template, wherein the frame is formed by surrounding a plurality of frames. Present frame is mostly the single structure of platykurtic, in order to guarantee structural strength, must increase its thickness, causes whole heavy, and it can't increase the working strength when the template equipment and the degree of difficulty of demolising with adjacent template and frame lug connection moreover, uses very inconveniently.

To solve the above problems in the prior art, we propose a frame assembly for a building template.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a frame subassembly for building templates that structural strength is high, the dismouting of being convenient for, turnover is fast, long service life.

In order to achieve the above object, the utility model provides a following technical scheme: a frame component for a building template comprises two frames which are symmetrical in structure and combined for use, wherein the frames are tubular structures with special-shaped rectangular sections; the frame comprises a straight wall, and the pipe wall opposite to the straight wall is inwards sunken to form an arc-shaped concave surface; one side wall of the frame is bent inwards to form an arc-shaped side wall, and a clamping groove for embedding the clamping device is formed in the other side wall opposite to the arc-shaped side wall along the length direction of the frame; the straight wall is provided with a plurality of template connecting holes for connecting the template, and the side wall opposite to the frame is symmetrically provided with a plurality of positioning holes; when the two frames are used in combination, the arc-shaped side walls of the two frames with symmetrical structures are oppositely arranged.

Preferably, the radian of the arc concave surface is 80-100 degrees.

Preferably, the radian of the arc-shaped side wall is 25-35 degrees.

Preferably, the material of the frame is high-strength steel.

Preferably, the aperture of the positioning hole is 5-10 mm.

Compared with the prior art, the beneficial effects of the utility model are that: (1) the straight wall is provided with a positioning hole, and the straight wall can be connected and assembled with the template through a screw; (2) clamping grooves are formed in the two sides of the frame assembly, the frame and the template can be fixedly connected by matching with corresponding clamping devices, the frame and the template can be conveniently detached after the frame assembly is used, and the turnover use of the template and the frame is accelerated; (3) 2 frames are combined in the assembling process, so that the structural strength of the frame is ensured; (4) the frame is provided with the arc lateral wall, has reduced the area of contact of two adjacent frames, has reduced the friction between the two, has reduced the wearing and tearing of frame, and the dismouting used repeatedly of being convenient for simultaneously has prolonged the life of frame.

Detailed Description

The following describes a preferred embodiment of the present invention with reference to the drawings, and the technical solution of a preferred embodiment of the present invention will be clearly and completely described.

Referring to fig. 1-2, the present invention includes two symmetrical and combined frames, wherein the frame is a tubular structure with a special-shaped rectangular cross section; the frame comprises a straight wall 4, and the pipe wall opposite to the straight wall 4 is inwards sunken to form an arc-shaped concave surface 1; one side wall of the frame is bent inwards to form an arc-shaped side wall 2, and a clamping groove 3 for embedding the clamping device is formed in the other side wall opposite to the arc-shaped side wall 2 along the length direction of the frame; the straight wall 4 is provided with a plurality of template connecting holes for connecting with a template, and the side wall opposite to the frame is symmetrically provided with a plurality of positioning holes 5; when the two frames are used in combination, the arc-shaped side walls 2 of the two frames with symmetrical structures are oppositely arranged.
