Problems solved by technology

[0002] At present, in order to facilitate transportation and production, most of the combined mandrels are used. The stress concentration at the joint of the mold tiles, the combined mandrel and mold tiles are easily deformed by external forces, resulting in unstable dimensions and poor compression resistance.

Embodiment 1

[0014] Embodiment 1, in the present invention, two mold tiles 3 are relatively combined to form a combined core mold 1, and more than one groove 4 is provided on the contact surface of the two mold tiles 3, and the grooves 4 are embedded with anti-corrosion molds penetrating through both sides of the mandrel. The compression strip 2 can effectively prevent the outer edge of the mandrel from opening outwards when the mold tile 3 is under pressure, which greatly increases the strength of the mandrel. refer to Figure 1 to Figure 2 .

Embodiment 2

[0015] Embodiment 2, the shape of the groove 4 opened on the mold tile 3 is semicircular, square or V-shaped, and it can be formed by one-time molding or secondary processing. refer to Figure 1 to Figure 2 , all the other are with embodiment 1.

Embodiment 3

[0016] Embodiment 3, the anti-compression braces 2 are composed of pull rods 6 and pull caps 5, and the distance between the pull caps 5 is the length between the outer frames of the mandrel. refer to Figure 1 to Figure 2 , and the rest are the same as the above-mentioned embodiment.

Abstract

The invention provides a combined core mold provided with compression-resisting tension bars and used for cast-in-place concrete. The combined core mold provided with the compression-resisting tension bars and used for the cast-in-place concrete mainly solves the technical problems that an existing core mold is instable in size and can not resist pressure when being processed, assembled and used due to the fact that external force acts on mold shoes of the combined core. The combined core mold provided with the compression-resisting tension bars and used for the cast-in-place concrete is characterized in that the combined core mold (1) is formed by oppositely combining two mold shoes (3), the contact faces of the mold shoes (3) are each provided with one or more grooves (4), and the compression-resisting tension bars (2) are embedded in the grooves (4) and penetrate through the two edges of the core mold. The combined core mold provided with the compression-resisting tension bars and used for the cast-in-place concrete is mainly applied to long-space and large-bay civil and public buildings.

Description

technical field [0001] The invention relates to a combined core mold for cast-in-place concrete with anti-compressive braces. Background technique [0002] At present, in order to facilitate transportation and production, most of the combined mandrels are used. The stress concentration at the joint of the mold tiles makes the mold tiles of the combined mandrel easily deformed by external forces, resulting in unstable dimensions and poor compression resistance. Contents of the invention [0003] The purpose of the present invention is to provide a combined mandrel for cast-in-place concrete with anti-compression braces, which has strong compression resistance and is not easily deformed. [0004] The technical solution adopted by the present invention to solve the technical problem is: two mold tiles 3 are relatively combined to form a combined mandrel 1, and more than one groove 4 is provided on the contact surface of the two mold tiles 3, and the groove 4 is embedded Ther...
