Description
The utility model relates to a kind of plug connector of wall thermal insulating system, particularly is used for the grafting bolt of cast-in-situ wall external thermal insulation in construction work.
The outer wall heat insulating form is more and more favored in construction work, so-called outer wall heat insulating is meant that insulation layer is positioned at the outdoor face rather than the chamber internal surface of body of wall, what wherein the type of attachment of the insulation layer of cast-in-place wall and body of wall adopted at present usually is to utilize bonding agent directly bonding, the bonding force intensity of this mode is generally less, insulation layer is directly born load, its insulation layer external surface can only be selected the polymer mortar outside finish for use usually, because insulation layer is directly born load, its bearing capacity is less, so the surface generally can not Wall brick etc. finish material, its cost is high, has increased building costs.Other type of attachment be when the construction of cast-in-place wall, adopt oblique cutting steel wire between body of wall and insulation layer and realize to insulation layer be connected and fixing, steel wire is unsatisfactory to the fixed effect of insulation layer in this mode, insulation layer very easily walks when building body of wall, distance between insulation layer and the construction formwork is difficult to be consistent, thereby the became uneven that directly causes surface decorations layer, the insulation layer cracking resistance is relatively poor, occurs face crack easily; The oblique cutting steel wire that gathers forms a lot of heat bridges, and heat insulation effect is reduced greatly; Its surface bears power is less equally, still has the unfavorable technical barriers of finish material effect such as surperficial Wall brick.In addition, also occurred before this by connecting the fixedly technology of insulation layer of fastener, it has overcome above-mentioned shortcoming to a great extent, but this connection fastener need be to the prefabricated in advance shaping of heat insulating material with the insulation layer clamping time, make it have corresponding bayonet socket, though the convenience of construction, flexibility are increased, also its corresponding building costs that increased.
The purpose of this utility model provides a kind of grafting bolt that is used for cast-in-place wall external insulation system, by using this grafting bolt not only can improve the convenience of construction greatly, flexibility, adjust the distribution density of inserting the knot bolt arbitrarily according to different needs, reduce construction costs, and can realize that body of wall is connected with the reliable of insulation layer, has good stressed property, substantially stop insulation layer and bear load, make the screed of insulation layer surface possess enough bearing capacities, can satisfy the facing requirement of various surperficial Wall bricks or other finish material, have good surperficial cracking resistance, and can avoid heat bridge to exist, guarantee heat insulation effect.
For achieving the above object, the utility model is taked following technical scheme:
The grafting bolt of this cast-in-place wall external insulation system comprises plastics grafting body, chassis and metal rod three parts, described grafting body forms by at least two plates are crossing at an angle, one end and the chassis of plate are connected as a single entity, the other end is tip-angled shape, described metal rod is embedded within the intersection volume of plate along the intersection axis of plate, and expose threaded termination at the center chassis place, and be equipped with corresponding nut.
As further improvement of the utility model, the central part on described chassis is provided with shrinkage pool, the threaded end of metal rod is revealed within this shrinkage pool and does not exceed shrinkage pool, the nut that matches with threaded end be belt end and on the termination, be provided with in the long nut of cross or interior hexagonal, and be equipped with " U " shape pad and opening flat shim; The outer of described plate all is made as blade-like, and the plate outer also is provided with reinforcing bar draw-in groove and limited bayonet; Be equipped with openwork part on plate and the chassis; The not bared end of metal rod also is made as shape of threads.
Utilize technique scheme, the grafting bolt that several the utility model can be invented in the cast-in-situ wall construction inserts and passes the warming plate of polyphenyl material, and reinforcing bar is stuck in the reinforcing bar draw-in groove of plate outer, thereby realized fixing and assembling to warming plate, the part that grafting body that should the grafting bolt during concreting passes warming plate is embedded among the concrete wall, warming plate is tightly blocked on the chassis of grafting bolt, after body of wall is built and is finished, the expanded metal lath that will be used for the facing mortar layer installs and fixes by the threaded end and the nut of metal rod, and then finishes the construction of facing mortar layer.Grafting bolt of the present utility model can insert from the optional position of warming plate, as long as assurance has the reinforcing bar draw-in groove of the grafting bolt of some to be stuck on the reinforcing bar, so do not need accurate location during operation, tip-angled shape head that the grafting bolt is sharp and the design of the blade-like of plate outer are enough to guarantee the grafting bolt is inserted and pass warming plate smoothly, so need or do other prefabricated shaping to the prefabricated in advance socket of warming plate, can also realize adjusting arbitrarily the distribution density of grafting bolt thus according to the different bearer needs, such scheme has improved the convenience of construction greatly, flexibility, saved manpower and construction material and, reduced construction costs the prefabricated processing charges of warming plate.And, the load that the wall facing layer is born all concentrates on the grafting bolt basically, and pass to concrete wall, insulation layer is not born load substantially except that deadweight, the steel that this grafting bolt adopts plastics grafting body to be embedded in metal rod is moulded complex form, it has higher-strength, warming plate is carried out form reliable the connection with in-situ concrete wall when self connects in realization, distribution density that also can be by adjusting the grafting bolt is to adapt to different surface bears requirements, thereby the screed that makes insulation layer surface possesses enough bearing capacities, can satisfy the facing load bearing requirements of various surperficial Wall bricks or other finish material, and the plastics grafting body that covers metal rod can avoid heat bridge to exist, thereby has guaranteed heat insulation effect.Simultaneously, owing to used grafting bolt of the present utility model, then can use expanded metal lath in the facing mortar layer, for gauze wire cloth, it has obviously superior surperficial cracking resistance.
Central part on above-mentioned chassis is provided with shrinkage pool, make the threaded end of metal rod be revealed within this shrinkage pool and do not exceed shrinkage pool, when construction, can avoid this threaded end to answer back to mutually with construction formwork, correspondingly use described long nut then can realize fixing to the expanded metal lath of facing mortar layer in the case, " U " shape pad can guarantee to maintain a certain distance between expanded metal lath and the warming plate, use the opening flat shim then can realize earlier nut being screwed on the threaded end, expanded metal lath is tightened and is hung on the nut termination again, again the opening plain cushion is stuck in the nut end, at last tighten operation sequence with interior cross set on the nut termination or interior hexagonal, it is convenient to operation, and can effectively realize tightening expanded metal lath is smooth.Set openwork part can increase grafting bolt and concrete wall bond stress on the limited bayonet of plate outer and the plate, and limited bayonet also has the positioning action to metal rod in to the process of grafting bolt.The not bared end of metal rod is made as shape of threads, can increase the bond stress of metal rod and plastics grafting body.Establish openwork part on the chassis, can save material, reduce deadweight.
