Abstract

The invention provides a steel structural fireproof body. The steel structural fireproof body comprises a steel structural body; an opening is formed in one side of the steel structural body; an end cover is arranged at the opening in the steel structural body; the part in which the end cover is connected with the steel structural body is a step structure; the end cover and the steel structural body are fixedly connected to the step structure by welding; a water inlet is formed in the end cover; a heat absorbing heat-change layer which is manufactured from FTC phase-change energy saving material is arranged on the sidewall of the steel structural body; a water absorbing and retaining layer which is manufactured from potassium polyacrylate is arranged in a cavity of the steel structural body. The steel structural fireproof body is simple in structure and convenient to use; the water absorbing and retaining layer is arranged in the steel structural body; therefore, the fire resistance of the steel structure can be greatly improved.

Description

A kind of steel structure fireproofing body

Technical field

The present invention relates to field of steel structure, specifically refer to a kind of steel structure fireproofing body.

Background technology

Steel work has been a kind of accessory be widely used at present, and the scope of application in multiple field also increases gradually, and its quality is light, intensity is high, stability is strong; But originally there is larger problem in fireproof high-temperature resistant aspect in steel work, such as, applying external force unexpected under high-temperature condition can cause the destruction suddenly of steel work all the time.

Summary of the invention

In order to solve the problem, the invention provides a kind of steel structure fireproofing body.

Concrete technical scheme is:

A kind of steel structure fireproofing body, comprise steel work body, steel work body side is opening; Steel work body openings place is provided with end cap; Described end cap and steel work body junction are ledge structure, and at ledge structure place, end cap is fixedly connected with steel work body by welding, and described end cap is provided with water inlet; Steel work body sidewall is provided with heat absorption phase change layer; Water-absorbing-retaining layer is provided with in the cavity of steel work body.

Further, described heat absorption phase change layer uses FTC phase transformation energy-saving material to make.FTC phase transformation energy-saving material breaks through the single resistive properties of Conventional insulation, has hot melt and the large thermal insulation of thermal resistance two.By binary Transformation Principle, latent heat of phase change value is large, has higher thermal storage density, stores, the nearly quasi-isothermal feature of exothermic process, and energy-saving effect is obvious.

Further, described water-absorbing-retaining layer is made by polyacrylic acid potassium.

Structure of the present invention is simple, easy to use, by arranging water-absorbing-retaining layer in steel work body, therefore drastically increases the refractoriness of steel work.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Wherein:

1. steel work body 2. end cap 3. water inlet 4. absorbs heat phase change layer

5. water-absorbing-retaining layer

Detailed description of the invention

A kind of steel structure fireproofing body, comprise steel work body 1, steel work body 1 side is opening; Steel work body 1 opening part is provided with end cap 2; Described end cap 2 and steel work body 1 junction are ledge structure, and at ledge structure place, end cap 2 is fixedly connected with steel work body 1 by welding, and described end cap 2 is provided with water inlet 3; Steel work body 1 sidewall is provided with heat absorption phase change layer 4; Water-absorbing-retaining layer 5 is provided with in the cavity of steel work body 1.

Structure of the present invention is simple, easy to use, by arranging water-absorbing-retaining layer in steel work body, therefore drastically increases the refractoriness of steel work.
