Battery mold for large prefabricated composite wallboard

Abstract

The invention discloses a battery mold for a large prefabricated composite wallboard, relates to the technical field of buildings and mainly solves the problem that heat-insulation boards are dislocated due to the fact that the light heat-insulation boards produce buoyancy during pouring when composite wallboards provided with heat-insulation layers are prefabricated with existing battery molds. The mold comprises a fixed mold and moving molds arranged on two sides of the fixed mold respectively; the mold is characterized in that two parallel bottom molds or bottom molds with concave cross sections are arranged at the bottom of a mold cavity between the moving molds and at the bottom of the mold cavity between the moving molds and the fixed mold; the distance between the two parallel bottom molds is consistent with the thickness of heat-insulation boards; and the thickness of concave grooves in the bottom molds with the concave cross sections is consistent with the thickness of the heat-insulation boards. With the mold, concrete is prevented from entering lower sides of the heat-insulation boards in such a manner that the heat-insulation boards are clamped by the bottom molds, so that the buoyancy cannot be produced, the problem of floating dislocation of heat-insulation materials in the concrete is solved, the materials are easy to feed during pouring, and cavities are avoided.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a vertical form for prefabricating a large wall panel in a whole room. Background technique [0002] In the field of residential industrialization, prefabricating the entire large wall panel and forming a group of vertical molds have the advantages of fast speed and double-sided flatness; the current technical vertical mold cannot prefabricate composite wall panels with insulation layers, because when the vertical mold is poured, 3 meters The deep concrete created enormous buoyancy for the lightweight insulation panels, causing them to be severely misaligned. Contents of the invention [0003] The object of the present invention is to address the above-mentioned deficiencies, and propose a vertical formwork for grouping of prefabricated composite large wallboards that does not generate buoyancy and dislocation when the vertical formwork is poured, and the wallboards that a...

Problems solved by technology

[0005] The present invention is based on the principle that the buoyancy of objects in the liquid is produced by the pressure difference between the upper and lower sides. The method of clamping the heat preservation board by the bottom mold prevents the concrete from entering the bottom of the heat preservation board and cannot produce buoyancy, and solves the problem that the heat preservation material is stuck in the concrete.
