Abstract
The utility model discloses a let out and explode hasp for wallboard. Including structure girder steel and wallboard, the structure girder steel is fixed in on the wallboard top through the hinge on, the wallboard bottom sets up the wedge shrouding, and wedge shrouding below sets up the hasp, and the hasp is fixed in on the structure girder steel. The utility model discloses mainly used steel sheet sandwich type wall panel. Use the utility model discloses the wallboard is exploded to technique preparation, letting out of installation, explodes the in -process and does not produce the explosion fragment letting out, the reducible secondary calamity that probably causes because of the explosion to furthest reduces the building and lets out the repair costs after exploding.
Description
Technical field
The utility model relates to a kind of venting of dust explosion snap close being applied to wallboard, particularly relates to a kind of venting of dust explosion snap close for sandwiched with steel plates wallboard.
Background technology
Because specific production technology or storage material may leak out imflammable gas or dust in factory (storehouse) room, under certain condition, detonation positive pressure of shock wave can be produced.In order to reduce the destruction to fabric structure in the state of accident, need to take measures on the maintenance body of wall of building timely and effectively by the emptying outdoor of releasing of pressure of detonation generation.
The venting of dust explosion wall board structure of existing specialty mainly contains two classes, one class adopts special venting of dust explosion bolt to fix light steel class wallboard, when acting on the pressure on wallboard under accident condition and reaching certain value, by the surrender of venting of dust explosion spacer for bolt, wallboard is come off, reach the object of pressure release.The subject matter of this make is under the effect of windy area wind shake, because the limited strength of venting of dust explosion spacer for bolt easily naturally loosens and comes off, need periodic maintenance to change, bolt cost and maintenance cost higher, and the reliability that building normally uses is affected.Another kind of is the maintenance body of wall (door and window) adopting the fragile material (sheet material) of surface density≤60kg/ ㎡ to do building, when acting on the pressure on wallboard under accident condition and reaching certain value, reached the object of pressure release by the fragmentation of wallboard (glass of door and window).The subject matter of this make is that explosive damage its heading of a large amount of fragments produced and the scope of splashing down can not get effective control in the state of accident, the raw secondary disaster of produce of easily hurting sb.'s feelings, and can only change and cannot repair after this venting of dust explosion structure destruction.
Utility model content
The purpose of this utility model needs periodic maintenance for explosion venting device in prior art and can only change shortcomings such as cannot repairing after destruction, and provide a kind of venting of dust explosion snap close being applied to wallboard newly.
The utility model provides a kind of venting of dust explosion snap close for wallboard, comprise structural steel beam and wallboard, it is characterized in that: wallboard top is fixed in structural steel beam by hinge, wallboard bottom arranges wedge shape shrouding, arrange snap close below wedge shape shrouding, snap close is fixed in structural steel beam.
The further technical characteristic of the utility model is: described snap close by vertical section, horizontal segment and the section of warping three part form, vertical section bottom is connected with horizontal segment one end, and the horizontal segment other end is connected with the section of warping, and the angle of the section of warping and horizontal segment is 20 ~ 45 degree.
The further technical characteristic of the utility model is: described wedge shape shrouding and latch components once molding formed by steel plate.
The utility model is mainly used in sandwiched with steel plates wallboard.Its advantage is compared with prior art: use a kind of venting of dust explosion snap close for wallboard provided by the utility model, when acting on the pressure on wallboard under accident condition and reaching certain value, the distortion of wedge shape shrouding bottom the amount of deflection produced by wallboard and wallboard, to make bottom wallboard automatic slippage snap close and on outward winding and open, to realize decompression function; Adopt the venting of dust explosion wallboard of the utility model fabrication techniques, installation, in venting of dust explosion process, do not produce explosive fragments, can effectively reduce the secondary disaster that may cause because of blast; Wallboard after venting of dust explosion can recover normal operating condition by simply repairing, and decreases the rehabilitation cost after building venting of dust explosion to greatest extent.
By the drawings and specific embodiments, the utility model is described in further detail below, but does not limit scope of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of venting of dust explosion snap close for wallboard of the utility model.
Reference numeral shown in figure is:
1,9-structural steel beam, 2-wallboard, 3-wedge shape shrouding, 4-snap close, the vertical section of 5-, 6-horizontal segment, the 7-section of warping, 8-hinge.
Detailed description of the invention
As shown in Figure 1, a kind of venting of dust explosion snap close for wallboard, comprise structural steel beam 1 and wallboard 2, wallboard 2 top is fixed in structural steel beam 1 by hinge 8, and wallboard 2 bottom arranges wedge shape shrouding 3, snap close 4 is set below wedge shape shrouding 3, snap close 4 to be fixed in structural steel beam 9, and wherein snap close 4 is made up of vertical section 5, horizontal segment 6 and the section of warping 7 three part, and vertical section 5 bottom is connected with horizontal segment 6 one end, horizontal segment 6 other end is connected with the section of warping 7, and the section of warping 7 is 20 ~ 45 degree with the angle of horizontal segment 6.
Described wallboard top adopts hinge 8 to link with the girder steel supporting wallboard, and normal condition wainscot sheathing bottom adopts steel wedge type snap close to be fixed by wallboard.
Use the utility model technology, when explosion happens, the effect that the inner side of wallboard 2 is subject to Dynamic load of nuclear blast will make wallboard 2 outwards produce deflection deformation, the wedge shape shrouding 3 of wallboard 2 bottom also will produce appropriateness distortion simultaneously, making, wallboard 2 constraint automatically that disengaging snap close 4 constructs below is outwarded winding opens, to meet the requirement of venting of dust explosion (pressure).
Claims (3)
1. for a venting of dust explosion snap close for wallboard, comprise structural steel beam and wallboard, it is characterized in that: wallboard top is fixed in structural steel beam by hinge, wallboard bottom arranges wedge shape shrouding, and arrange snap close below wedge shape shrouding, snap close is fixed in structural steel beam.
2. a kind of venting of dust explosion snap close for wallboard according to claim 1, it is characterized in that: described snap close by vertical section, horizontal segment and the section of warping three part form, vertical section bottom is connected with horizontal segment one end, the horizontal segment other end is connected with the section of warping, and the section of warping is 20 ~ 45 degree with the angle of horizontal segment.
3. a kind of venting of dust explosion snap close for wallboard according to claim 1, is characterized in that: described wedge shape shrouding and latch components once molding formed by steel plate.
