Micro-foam double-machine co-extrusion three-layer square-grid building formwork

Abstract

The invention relates to building formworks, and particularly discloses a micro-foam double-machine co-extrusion three-layer square-grid building formwork which comprises a base plate. Hollow structures are arranged in the base plate, glass fiber layers and white flame-retardant plastic layers are sequentially arranged on two sides of the base plate from the inside to the outside, arc-shaped protrusions are arranged on the tops of the white flame-retardant plastic layers, white heat dissipation paint layers are sprayed on the outer side surfaces of the white flame-retardant plastic layers, twoinsertion structures are arranged on the two sides of the base plate, a square connecting lug is arranged on one of the insertion structures, a square connecting block is arranged on the other insertion structure, circular through holes are formed in the center of the square connecting lug and the center of the square connecting block, and a circular connecting rod is inserted in the circular through hole in the square connecting block; two sealing components are arranged at two ends of the base plate, and pins which can be inserted in the hollow structures are arranged on the sides of the two sealing components. The micro-foam double-machine co-extrusion three-layer square-grid building formwork has the advantages that mud can be prevented from flowing into the hollow structures, the difficulty in connection between building formworks can be lowered, the heat dissipation speeds can be increased, the fireproof ability can be enhanced, and the micro-foam double-machine co-extrusion three-layer square-grid building formwork can be prevented from being bent when loaded.

Description

technical field [0001] The invention relates to the technical field of building templates, in particular to a micro-foaming double-machine co-extruded three-layer grid building template. Background technique [0002] Today's building formwork is widely used in the construction industry. In the process of preparing concrete structures, building formwork plays a key role. However, today's building formwork has the following problems: First, in order to save materials, it is generally used in building formwork. A hollow structure is added inside, and this hollow structure is often blocked by flowing mud. The hardening of the mud will reduce the deformation resistance of the building formwork, increase the weight of the building formwork, and increase the workload of the carrier; the second is between building formwork. The connection is cumbersome and requires a large number of external tools to complete the connection. The connection process is cumbersome. Third, because the m...

[0002] Today's building formwork is widely used in the construction industry. In the process of preparing concrete structures, building formwork plays a key role. However, today's building formwork has the following problems: First, in order to save materials, it is generally used in building formwork. A hollow structure is added inside, and this hollow structure is often blocked by flowing mud. The hardening of the mud will reduce the deformation resistance of the building formwork, increase the weight of the building formwork, and increase the workload of the carrier; the second is between building formwork. The connection is cumbersome and requires a large number of external tools to complete the connection. The connection process is cumbersome. Third, because the material of the building formwork is dark in color, it is very hot after being exposed to the sun, which brings inconvenience to the user's assembly. Fourth, the fire resistance is poor. It is easy to spontaneously ignite when subjected to high temperature; fifth, the middle part of today's building formwork will be slightly bent when loaded, which will affect the dimensional accuracy of the concrete structure
