Embodiment 1

[0043] Figure 5 and Image 6 It schematically shows that an explosion venting bolt disclosed by the present invention is used in a rock wool sandwich steel plate explosion venting wall.

[0044] like Figure 5 and Image 6 As shown, the explosion venting wall 71 of rock wool sandwich steel plate is fixed on the wall beam 81 through a kind of explosion venting bolt disclosed by the present invention. The inner diameter of the explosion-venting bolt nut 11 is larger than the outer diameter of the explosion-venting bolt nut 11. The screw rod 12 of the explosion-venting bolt passes through the through hole on the rock wool sandwich steel plate explosion-venting wall 71, and passes through the self-tapping function of the self-tapping head at the end of the screw rod. Pass through the wall beam 81 and be fixedly connected with the wall beam 81. The metal sleeve 3 is located in the through hole of the rock wool sandwich steel plate explosion vent wall 71 to strengthen the cooper...

Embodiment 2

[0046] Figure 7 and Figure 8 It schematically shows that an explosion venting bolt disclosed by the present invention is used in a single-layer color steel plate explosion venting wall.

[0047] like Figure 7 and Figure 8 As shown, the single-layer color steel plate explosion-venting wall 72 is fixed on the wall beam 82 through a kind of explosion-venting bolt disclosed by the present invention. In this embodiment of the present invention, the single-layer color steel plate explosion-venting wall 72 and the wall beam 82 There are thermal insulation cotton layers 9 attached between them, and the thermal insulation cotton layers 9 play the role of thermal insulation and sound insulation. In addition, preferably, a stepped side plate 91 is also provided between the single-layer color steel plate explosion venting wall 72 and the insulation cotton layer 9, such as Image 6 As shown, the side plate 91 is in a stepped shape and is located at the joint position of two single-...

Embodiment 3

[0049] Figure 9 and Figure 10 It schematically shows that an explosion-venting bolt disclosed in the present invention is used to fix the explosion-venting window 73 on the building keel 83 .

[0050] like Figure 9 and Figure 10 As shown, one side of the explosion-venting window 73 is connected to the building keel 83 through a hinge 831, and the side of the explosion-venting window 73 opposite to the hinge 831 is fixedly connected to the building keel 83 through an explosion-venting bolt disclosed in the present invention. . It is basically the same as Embodiment 1. During installation, a through hole is provided on the explosion-venting window 73, and the inner diameter of the through-hole is greater than the outer diameter of the explosion-venting bolt nut 11, and the screw rod 12 of the explosion-venting bolt passes through the through-hole on the explosion-venting window 73. hole, and through the self-tapping function of the self-tapping head at the end of the scr...

Abstract

The invention discloses an explosion venting bolt. The explosion venting bolt comprises a bolt body and a metal gasket sheathing a screw of the bolt body, wherein a metal sleeve sheathes the screw, the metal gasket sheathes the nut end of the bolt body and is positioned between the metal sleeve and a nut, an elastic gasket also sheathes the screw between the metal sleeve and the metal gasket, the metal sleeve is made from hard metal, the metal gasket is made from soft metal, and the metal gasket and the elastic gasket are bonded into a whole. The explosion venting bolt provided by the invention has the advantages that the metal sleeve sheathes the screw, the metal sleeve has the effect of preventing energy collapse, plate energy absorption can be reduced, the metal gasket is firstly destroyed during explosion, and the metal sleeve deforms, so that a metal door, metal windows and metal plates are protected, secondary damage is reduced, and loss caused by the explosion is reduced; meanwhile, a waterproof gasket is also arranged between the metal gasket and the nut, and an annular step of the nut is combined, so that a pore can not be formed between the waterproof gasket and the nut, and the waterproof property is further improved.

Description

technical field [0001] The invention relates to the field of explosion-venting fasteners, in particular to an explosion-venting bolt capable of effectively absorbing shock waves with relatively small plates. Background technique [0002] Explosion-venting walls are usually light-weight pressure-relieving walls used in boiler rooms of industrial and civil factories, dangerous goods warehouses, etc. When an explosion or combustion occurs in a building, the gas pressure in the room rises sharply. The explosion-venting wall passes through explosion-venting accessories or The device opens the wall and releases pressure to control the explosion or minimize damage. [0003] Explosion-venting accessories are usually composed of explosion-venting bolts and traction nooses. Among them, the role of explosion-venting bolts is to quantify the value of the explosion-venting pressure and dynamically control the release pressure. [0004] For example, Chinese patent CN201982746U discloses ...
