Embodiment Construction

[0012] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] see figure 1 , figure 1 It is a cross-sectional schematic diagram of a high-temperature resistant beam, including: skeleton 1, expansion fire-retardant glue 2 wrapped on skeleton 1, and heat-insulation layer 3 wrapped outside expansion fire-retardant glue 2. In the event of a fire, the heat-insulation l...

Abstract

The invention provides a high-temperature resistant crossbeam. Through an arranged skeleton, expansion fire retardant glue and a heat-insulating layer, wherein the skeleton is wrapped with the expansion fire retardant glue and the expansion fire retardant glue is externally wrapped with the heat-insulating layer, when a fire occurs, the quite good fire retardant and heat-insulating effects are achieved through the heat-insulating layer, outside heat is prevented from being transferred to a crossbeam body, the expansion fire retardant glue is quickly expanded in size when being heated, the heat-insulating and fire-proof effects are further achieved, meanwhile, the water-proof effect can further be achieved to isolate the crossbeam from outside air, and corrosion is prevented so as to prolong the service life of the crossbeam.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a high-temperature-resistant beam. Background technique [0002] At present, as people pay more and more attention to the safety of factory buildings, the requirements for the fire performance of building materials are also getting higher and higher. The workshops of some companies are usually built with steel beams, which will be corroded continuously during use, reducing the service life. In the construction of some companies' workshops, only the decoration materials are required to have good fire resistance and high temperature resistance performance, such as Gypsum board, magnesium oxide board, calcium silicate board, etc., these materials are decorated, but the main frame of the factory building and the beams that play a supporting role are not used for construction with materials with good high temperature resistance and fire resistance, and fires will occur in...
