Description

A kind of connection fastener of cast-in-place wall external thermal insulation

The utility model relates to a kind of connection fastener of wall insulating layer, particularly is used for the connection fastener of cast-in-situ wall external thermal insulation in construction work.

The outer wall heat insulating form more and more is subjected to the parent and looks 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, wherein the type of attachment of the insulation layer of cast-in-place wall and body of wall adopts two kinds of forms at present usually: a kind of is to utilize bonding agent directly bonding, the bonding force intensity of this mode is generally less, warming plate is directly born external load, its warming plate external surface can only be selected the thick polymerization mortar outside finish of 3～5mm usually for use, because warming plate is directly born external load, its bearing capacity is less, so the surface generally can not Wall brick, finish materials such as light stone, and its cost is high, has increased building costs.Another kind of type of attachment be when cast-in-place wall construction, 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 directly cause the became uneven of surface decorations layer, construction is caused very burden; 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 result of use such as surperficial Wall brick, light stone.

The purpose of this utility model provides a kind of connection fastener of cast-in-place wall external thermal insulation, can realize that by using this connection fastener body of wall is connected and accurate location with the reliable of insulation layer, it has good force-bearing property, substantially stop warming plate and bear external load, make the finish coat on warming plate surface possess enough bearing capacities, can satisfy the facing requirement of various surperficial Wall bricks, light stone or other finish material, and can avoid heat bridge to exist, guarantee heat insulation effect, simultaneously can also realize easy construction, reduce purposes such as construction costs.

For achieving the above object, the utility model is taked following technical scheme:

The connection fastener of this cast-in-place wall external thermal insulation comprises a plastics fastener and a metal rod, and this plastics fastener has each one of the forward and backward clamp that is parallel to each other, and forward and backward clamp links to each other by perpendicular panel, and panel is extended by the back clamp; This metal rod is embedded among the panel of plastics fastener and runs through forward and backward clamp, and exposes threaded termination at preceding clamp one end, and is equipped with corresponding nut.

As further improvement of the utility model, the preceding clamp of above-mentioned plastics fastener is provided with groove, the threaded end of metal rod is revealed within this groove, 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; Both sides, panel middle part between forward and backward clamp are provided with horizontal supporting plate; On the panel that extends by the back clamp, be provided with the reinforcing bar draw-in groove, also be provided with openwork part on the whole panel; The not bared end of metal rod is a bending.

When cast-in-situ wall is constructed, the connection fastener that utilizes the utility model to invent can be realized the convenient clamping assembling to warming plate, wherein the panel that is extended out by the back clamp of plastics fastener is partly built among concrete wall, panel between the clamp of front and back is embedded among the warming plate, and by the clamping location of forward and backward clamp realization to warming plate, after body of wall is built and is finished, be used for the gauze wire cloth of facing mortar layer or expanded metal lath threaded end and the nut by metal rod and install and fix, and then finish the construction of facing mortar layer.By using connection fastener of the present utility model, the load that the wall facing layer is born all concentrates on basically and connects on the fastener, and passes to concrete wall, and insulation layer is not born load substantially except that deadweight.This connection fastener adopts the steel of buried metal rod member in the plastics fastener to mould 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, thereby the screed that makes insulation layer surface possesses enough bearing capacities, can satisfy the facing requirement of various surperficial Wall bricks or other finish material, and the plastics fastener that covers metal rod can avoid heat bridge to exist, thereby has guaranteed heat insulation effect.

At the preceding clamp of stating the plastics fastener groove is set, the threaded end of metal rod is revealed within this groove, when construction, can avoid this threaded end to answer back to mutually with construction formwork, use long nut then can realize in the case to the gauze wire cloth of facing mortar layer or fixing of expanded metal lath, " U " shape pad can guarantee to maintain a certain distance between gauze wire cloth or expanded metal lath and the warming plate, use the opening flat shim then can realize earlier nut being screwed on the threaded end, again gauze wire cloth or expanded metal lath are tightened and hung on the nut termination, 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 gauze wire cloth or expanded metal lath is smooth tightens.Horizontal supporting plate is set on panel can realizes the accurate clamping of warming plate is located, and can bear warming plate part weight.Reinforcing bar draw-in groove on the panel can be realized the clamping with reinforcing bar, thereby forms reliable the connection with concrete wall better, and forniciform metal rod termination also can increase with the reliable of body of wall and is connected.Hollow out is set on the panel can be increased to hold and close area and save material.Certainly,, when substituting high bonding agent, both be convenient to constructing operation, saved manpower, and also can realize freely selecting different outside finish forms, thereby reduced construction costs according to different needs by using this connection fastener.
