Embodiment 1

[0046] Figure 5 and Figure 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.

[0047] Such as Figure 5 and Figure 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, and the cooperatio...

Embodiment 2

[0049] 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.

[0050] Such as 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 Figure 6 As shown, the side plate 91 is in a stepped shape and is located at the joint position of two sin...

Abstract

The invention discloses an explosion venting bolt and an explosion venting window with the explosion venting bolt. The explosion venting bolt comprises a bolt body, a metal gasket and a metal sleeve; the metal gasket is positioned between the metal sleeve and a screw cap; a waterproof gasket is arranged between the metal gasket and the screw cap; an elastic gasket is arranged between the metal sleeve and the metal gasket; a damping washer is arranged at each of the two end parts of a screw rod in a sleeving manner; the damping washers are positioned in the cavity of the metal sleeve; and the damping washers are closely clamped between the metal sleeve and the screw rod. The explosion venting window comprises a window frame and a window sash, wherein one side of the window sash is rotatably connected with the window frame through a hinge, and the other side of the window sash is fixedly connected through the bolt body. According to the technical scheme provided by the invention, the metal sleeve has a collapse energy preventing function; when an explosion happens, the metal gasket 2 is damaged first, and the metal sleeve deforms, so that a metal door plate or window is protected, and the loss caused by the explosion is reduced; and when the explosion happens, the explosion venting window is opened quickly to vent explosion pressure outwards quickly, so that great loss of indoor personnel lives and property are avoided.

Description

technical field [0001] The invention relates to the technical field of explosion-proof safety, in particular to an explosion-venting bolt and an explosion-venting window provided with the explosion-venting bolt. 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] Another example is that Chinese patent CN101749...
