Problems solved by technology

[0004] The problem in the prior art to be solved by the present invention is that the structure of the explosion venting plate itself in the prior art in the field of construction is too complicated and the cost is high, thus providing a single-use explosion-venting plate with both load-bearing and explosion-venting functions. Explosion venting plate and preparation method thereof

Embodiment 1

[0032] Such as figure 1 , figure 2 as well as image 3 As shown, a directional explosion venting panel is characterized in that it includes a main body layer 2, an anti-crack layer 4, a filling layer, an external surrounding frame 3 and a traction noose 5; the main body layer is made of silicate material, and the main body There is an explosion venting groove 1 on the front of the layer; the anti-crack layer 4 is an anti-crack material; the filling layer is an adhesive, and the filling layer is arranged between the main body layer 2 and the anti-cracking layer 4; The frame 3 is arranged on the peripheral periphery of the main body layer 2 .

[0033] Preferably, the main body layer 2 includes an upper layer 21, a middle layer 22 and a lower layer 23, the middle layer 22 is a thermal insulation core layer, and the thermal insulation core layer is a foamed cement core layer, a cement perlite core layer and a cement core layer. One or more combinations in the core layer of pol...

Embodiment 2

[0046] Such as Figure 4 to Figure 8, the innovation of this application is to set up the explosion venting groove 1 on the main body of the explosion venting plate. When the explosion occurs, the whole plate will be impacted by the shock wave, because the explosion venting groove 1 is thinner than the surrounding area, and stress concentration will be formed. When the explosion vent plate is destroyed, it will start from the explosion vent groove 1, so as to realize the directional explosion venting. And the explosion vent groove 1 of the present application can be arranged freely, Figure 4 It is the layout method of explosion vent 1 commonly used in this application. It is a concentric circle mode. The center of the explosion vent plate is used as a concentric circle. The radius of the concentric circle is set according to the explosion venting requirements. The radius difference can be 10-50cm. When an explosion occurs , the middle of the explosion vent plate is the stres...

Embodiment 3

[0048] In the explosion venting plate described in this embodiment, the main body layer 2 is a silicate solid layer, and an explosion venting groove 1 is opened on the silicate solid layer; the main body layer 2 is divided into three layers: the upper layer 21 , the middle layer 22 and the lower layer 23; the middle layer 22 is a lightweight thermal insulation material layer, and the lightweight thermal insulation material layer is an inorganic vitrified microbead material, and the inorganic vitrified microbead material is filled on the main body layer holes; the external surrounding frame 3 is arranged on the periphery of the main body layer 2, and is an integrally formed inverted "L"-shaped structure.

[0049] The preparation method of the explosion-venting plate described in the present embodiment is as follows:

[0050] Step 1: first use an electric welding machine to weld the outer frame 3 into shape, and then form an integrated inverted "L" structure;

[0051] Step 2: S...

Abstract

A directional explosion venting plate is characterized in that the directional explosion venting plate comprises a main body layer, an anti-cracking layer, a filling layer, an external surrounding frame and a cable stretching hinge cable; the main body layer is made of a silicate material, and an explosion venting groove is formed in the front face of the main body layer; the anti-cracking layer is made of an anti-cracking material; the filling layer is an adhesive and arranged between the main body layer and the anti-cracking layer; and the external surrounding frame is arranged at the peripheral edge of the main body layer.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a directional explosion venting plate and a preparation method thereof. Background technique [0002] At present, the vast majority of existing buildings basically do not have pressure relief and explosion-proof facilities. Even warehouses that store inflammable and explosive materials or factory buildings that produce inflammable and explosive materials do not have special pressure relief and explosion-proof facilities. Therefore, once a chemical or physical explosion, including the explosion of flammable gas, dust and mixed gas, will instantly generate a powerful shock wave, destroy buildings and surrounding properties, resulting in huge economic losses and casualties. Therefore, In this case, it is necessary to take active active defense measures. Moreover, with the strengthening of people's concept of explosion-proof safety, people are increasingly aware of the importance o...
