Abstract
The invention relates to a non-keel dry-hanging fastener which belongs to the technical field of parts or structures especially used as fixing material during decorating walls of buildings. The non-keel dry-hanging fastener solves the problem that thermal-insulation decoration plates have no keel dry-hangings and comprises a clip and a fastening piece, wherein, the clip is an expansion bolt, and the center of the threaded rod of the expansion bolt is provided with an inner-threaded round hole; the fastening piece is connected with the threaded rod of the expansion bolt by a screw. The fastening piece consists of a top plate and a base plate which are respectively provided with a round hole. The fastener provided by the invention is made of stainless steel or metal, the surface of which is treated to resist against corrosion, and realizes that thermal-insulation decoration plates have no keel dry-hangings, so that thermal-insulation decoration plates can be perfectly fixed on walls. The fastener is applicable to various wall materials, such as concrete, solid and hollow walls and can make constructions and maintenance convenient and quick. The fastener has high loading capacity, high bearing pressure and good tension-resistance performance; besides, the fastener can prevent the impact damage, reduce the loading of a whole building, provide 3-5 cm horizontal adjustment differences for the distorted surfaces of walls, and provide flat surfaces for wall decoration.
Description
One, technical field
The invention belongs to part or component technology field that the building masonry wall finishing is used as immobilization material specially, particularly relate to fixedly crab-bolt of a kind of external wall outer insulation decorative panel.
Two, background technology
Practice at home and abroad shows, it is science, the most reasonable, the most most economical building energy conservation means that building is adopted External Thermal Insulation Technology for External and product, and so-called external wall outer insulation is meant on the external surface of vertical exterior wall and builds insulation layer.China's building energy conservation work is started late, and the heat preservation energy-saving transformation of existing building is not second to grassroot project, and its difficulty of construction will be much larger than new building; Moreover the wall body structure of existing building and facing form vary, and accumulating over a long period has deposited a large amount of dusts and dirt, remove and scrub very difficultly to be practically impossible in other words, and interfacial agents and bonding adhesive all can't normal constructions.And, domestic various places are in the process of applying External Thermal Insulation Technology for External and product, phenomenon such as come off hollowing, deflection, crack appearred and in building wall more or less, not only had influence on the energy-saving effect of building, also directly influenced the external thermal insulation system The Application of Technology.Therefore, fastness and safety in order to ensure external thermal insulation system, on the basis that bonding is fixed, the mode that adopts mechanical anchor to reinforce again, particularly in highrise building, when insulation position absolute altitude surpasses 20 meters, must adopt mechanical anchor to reinforce, and the safety factor of mechanical anchor system is not less than 5 times, promptly single crab-bolt tension bearing capacity limiting value 〉=1.5kN.For this reason, material that require to make screw is stainless steel or the metal handled through surface anticorrosion, and plastics expand tube and circle platen should adopt material such as nylon to make; The crab-bolt external member must be to be up to the standards through authoritative institution, and has survey report to adopt.But, the setting of crab-bolt tension bearing capacity and form of structure, locking mode, supporting capacity, usage quantity and the anchor point of anchoring piece and distribute directly related.At present common anchoring matrix external wall structure is very complicated, and common expansion bolt that only depending on expands in the past locks or nailing etc. are suitable for the anchoring requirement of diversified external wall structure.And adopt steel joist to carry out the plug-in construction of outside finish, and owing to adopt steel part to carry out the fixing of steel joist on the wall, the problem of cold and hot bridge appears inevitably, can cause the reduction of system's heat insulation effect; In addition, owing to adopt steel joist, the cost of construction increases.
Three, summary of the invention
The purpose of this invention is to provide a kind of keel-free direct hanging fastener, solved the problem of heat insulating decorative board keel-free direct hanging, it comprises anchoring piece and securing member, anchoring piece is an expansion bolt, screw rod center at expansion bolt offers the internal thread circular hole, securing member is connected with the expansion bolt screw rod by screw, securing member is made up of top board and base plate, securing member top board and base plate center offer circular hole, top board circular hole aperture is corresponding with screw diameter, base plate circular hole aperture is corresponding with the expansion bolt screw diameter, the securing member top board is for dull and stereotyped or on circular hole both sides and top board surface with grow that the limit is vertical to be provided with two positive and negative inverted "L" shaped integrated circuit boards, the securing member base plate is that flat board or inward at both ends are folded in half into " U " shape, fastener material therefor of the present invention is stainless steel or the metal handled through surface anticorrosion, the contact area of securing member and warming plate is bigger, make heat insulating decorative board can more firmly be attached at outer surface of wall, simultaneously, securing member can be embedded in the adjacent insulation and decoration panel, cover up " L " shape integrated circuit board with weather-resistant glue, thereby can not influence the outward appearance of building, realized the heat insulating decorative board keel-free direct hanging, can fix on heat insulating decorative board on the body of wall together better, be applicable to all kinds of materials for walls, as concrete, solid and hollow wall, and it is easy to maintenance quick to construct; The bearing capacity height, high pressure-bearing, tensile property are good, can prevent impact damage; Can alleviate whole building load; It is poor to provide the level of 3-5 centimetre to transfer to the body of wall warp surface, for wall body decoration provides even curface.
