Problems solved by technology

The first two are complete heat insulation protection methods, which are difficult to avoid high fire prevention costs and regular maintenance; the third mainly prevents the concrete structure from bursting, which is not effective in retarding the transfer of temperature, and will produce after fire. Cracks of a certain depth, causing damage to the structure

[0010] figure 2 Schematic diagram of the construction process of a fireproof material product used in concrete structures

[0011] Below in conjunction with accompanying drawing, the present invention will be further described:

[0012] This embodiment provides a regular quadrilateral conical fireproof material product for concrete structures, which consists of 9 standard regular quadrilateral conical fireproof blocks 1 that use high-density cement-based fireproof materials and are arranged equidistantly in a two-dimensional 3×3 pattern. The above-mentioned standard quadrilateral conical fire block 1 has an upper bottom surface of 40mm×40mm, a lower bottom surface of 60mm×60mm, and a height of 27mm. On the larger surface of 60mm×60mm, a layer of 3mm thick pure cement is attached to the lower bottom surface. Surface layer: the above 9 standard regular quadrilateral conical fire...

Abstract

The invention relates to a fireproof material product used for a concrete construction and a construction technique thereof. The fireproof material product is formed by a plurality of standard regular polygon taper fire blocks which are made of weighted cement based fireproof material and are arranged in parallel by an adjacent edge according to the two-dimensional isometry; the fireproof material product is positioned and connected by internally embedding a wire netting with the corresponding shape; when in construction, the side with vellum clings to a component templet; according to the size of the templet, a plurality of pieces of fireproof concrete components are arranged in the two-dimensional sequence in an extending way and then the components are provided with a steel reinforcement cage and is provided with concrete; after the concrete is condensed and formed, the removal of shuttering is carried out; by using the fireproof concrete construction and the construction technique thereof, the concrete construction is ensured not to burst and not to generate the injury caused by a fire crackle.

Description

technical field [0001] The invention relates to a fireproof material product for concrete structure and its construction technology. Background technique [0002] Traditional fire protection measures for concrete structures include: ① pasting fireproof boards on the concrete surface; ② spraying fireproof paint on the concrete surface; ③ adding chemical fibers and steel fibers to the concrete. The first two are complete heat insulation protection methods, which are difficult to avoid high fire prevention costs and regular maintenance; the third mainly prevents the concrete structure from bursting, which is not effective in retarding the transfer of temperature, and will produce after fire. Cracks of a certain depth cause damage to the structure. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, provide an effective fire prevention, and ensure that the concrete structure will neither burst nor cause damage c...
