Description
技术领域 technical field
本发明涉及建筑物的安全防范技术领域，尤其涉及一种降低爆炸破坏力的方法及泄爆装置。The invention relates to the technical field of building safety protection, in particular to a method for reducing explosion destructive force and an explosion venting device.
背景技术 Background technique
石油、化工、煤炭的国防等许多工业部门，在生产、加工、运输和贮存的各个过程中，经常可能泄露或溢散出各种各样的易燃易爆气体、液体和各种粉尘及纤维。这类物质与空气混合后，可能成为具有爆炸危险的混合物，当混合物的浓度达到爆炸浓度范围时，一旦出现火源即会引起爆炸和发生火灾等严重事故。鉴于此，有必要采取积极的主动防御措施和万一发生爆炸事故时有利于降低破坏力的有效措施。In many industrial sectors such as petroleum, chemical industry, coal, national defense, etc., various flammable and explosive gases, liquids, various dusts and fibers may often be leaked or spilled during the various processes of production, processing, transportation and storage. . After such substances are mixed with air, they may become explosive mixtures. When the concentration of the mixture reaches the explosive concentration range, once an ignition source occurs, it will cause serious accidents such as explosion and fire. In view of this, it is necessary to take active active defense measures and effective measures to reduce destructive power in case of an explosion accident.
现有技术中常使用的降低爆炸破坏力的方法在于使爆炸尽量发生在一定的空间范围内，将爆炸产生的冲击波隔离，使爆炸产生的破坏力最小。因此就必须用刚性材料阻隔爆炸产生的冲击波或者吸收冲击波。这就要求该刚性材料必须承受巨大的压力，但实际上爆炸产生的冲击压强是事先难以估量的，因此用于一般建筑物上的墙体或屋面材料事实上无法起到隔离爆炸破坏力的作用。The method commonly used in the prior art to reduce the destructive force of the explosion is to make the explosion occur within a certain space as much as possible, isolate the shock wave generated by the explosion, and minimize the destructive force generated by the explosion. Therefore, rigid materials must be used to block or absorb the shock waves generated by the explosion. This requires that the rigid material must withstand huge pressure, but in fact the impact pressure generated by the explosion is difficult to estimate in advance, so the wall or roof materials used in general buildings cannot actually play the role of isolating the destructive force of the explosion .
有鉴于此，现有技术中急需要一种新的降低爆炸破坏力的方法及泄爆装置，该方法或泄爆装置可以直接使用在一般建筑物上，既满足一般建筑物的保温、降噪的功能，还能有效降低因爆炸所导致的破坏力。In view of this, there is an urgent need for a new method and explosion venting device for reducing explosion destructive power in the prior art. This method or explosion venting device can be directly used on general buildings, which not only meets the requirements of thermal insulation and noise reduction of general buildings The function can also effectively reduce the destructive force caused by the explosion.
发明内容Contents of the invention

更进一步地，该两侧硅酸钙板之间至少还包括一龙骨，该填充物位于龙骨及该硅酸钙板组成的空间之内。Furthermore, at least one keel is included between the calcium silicate boards on both sides, and the filler is located in the space formed by the keel and the calcium silicate boards.
更进一步地，该龙骨与该硅酸钙板通过自攻螺丝固定。Furthermore, the keel and the calcium silicate plate are fixed by self-tapping screws.
更进一步地，该龙骨包括与建筑物的地面和天花板相接触的横向龙骨，以及与该横向龙骨相平行的穿心龙骨，以及与该横向龙骨垂直的竖向龙骨。Furthermore, the keel includes a transverse keel in contact with the floor and ceiling of the building, a penetrating keel parallel to the transverse keel, and a vertical keel perpendicular to the transverse keel.
更进一步地，该龙骨是横截面呈“ㄇ”形的金属型材。Furthermore, the keel is a metal profile with a "ㄇ" shape in cross section.
更进一步地，该穿心龙骨之间的间距为1.2米，该竖向龙骨之间的间距为0.4米。Furthermore, the distance between the center keels is 1.2 meters, and the distance between the vertical keels is 0.4 meters.
本发明同时还提供一种降低爆炸破坏力的方法，包括：将一泄爆板安装于一般建筑物的墙体或屋顶上，该泄爆板由位于最外两侧的硅酸钙板以及位于该两侧硅酸钙板之间的填充物组成，该填充物为岩棉。The present invention also provides a method for reducing explosion destructive force, comprising: installing an explosion venting plate on the wall or roof of a general building, the explosion venting plate is composed of calcium silicate boards located on the outermost two sides and The filler between the calcium silicate boards on both sides is composed of rock wool.
更进一步地，该两侧硅酸钙板之间至少还包括一龙骨，该填充物位于龙骨及该硅酸钙板组成的空间之内。Furthermore, at least one keel is included between the calcium silicate boards on both sides, and the filler is located in the space formed by the keel and the calcium silicate boards.
基于上述构思的本发明适用于墙体和屋面使用的泄爆装置，在房间内压力达到泄爆板的极限强度时，泄爆板断裂呈块状和粉末状，无尖锐棱角，密度低，离开爆炸中心的过程中不易造成伤害，而且保温层为轻质材料，泄压时不易造成二次伤害。此外由于所述的泄爆板上的内外层硅酸钙板具有隔音、防潮等作用，而且其内部填充的岩棉具有保温、吸音的作用，因此在建筑物墙体中设置该装置，不会影响建筑物的保温、隔音效果，另外由于硅酸钙板具有防潮和防虫蛀作用，能够有效实现建筑防潮防蛀，耐候性好，使用寿命长。其中的龙骨能够确保泄爆板的强度，不影响墙体或屋面稳定性。The invention based on the above concept is suitable for explosion venting devices used on walls and roofs. When the pressure in the room reaches the ultimate strength of the explosion venting plate, the explosion venting plate breaks in block and powder form, without sharp edges and corners, and has a low density. It is not easy to cause injury during the process of the explosion center, and the insulation layer is made of light material, so it is not easy to cause secondary injury when the pressure is released. In addition, because the inner and outer calcium silicate boards on the explosion-venting board have the functions of sound insulation and moisture resistance, and the rock wool filled inside has the functions of heat preservation and sound absorption, so installing this device in the building wall will not It affects the thermal insulation and sound insulation effect of the building.
