Description
Technical field
The utility model relates to the connector of a kind of anchor connector of composite sandwich body of wall, particularly a kind of prefabricated heat preservation wall body.
Background technology
Building energy conservation is a key of alleviating China's energy scarcity, and body of wall is energy-conservation to be the most important means that realize building energy conservation.The traditional heat-preserving wall of China is divided into two kinds of inside heat insulation wall body and external heat insulating walls.There is heat bridge phenomenon in inside heat insulation wall body, and base insulating layer is prone to crackle, reduces application life.Then there are problems such as fire prevention and the negative blast of opposing in external heat insulating wall.In order to address the above problem, in recent years, the sandwich type heat-preserving wall has obtained using widely.
Connector is the key member that connects prefabricated heat preservation wall body layer of concrete and insulation layer, and it mainly acts on is the shearing action of resisting between inside and outside layer of concrete and the insulation layer.At present, domestic existing its connector of sandwich type heat-preserving wall mostly adopts the metal lattice work muscle to connect, and easily produce heat bridge at the connector position, and the connector corrosion resistance is relatively poor.Because fibre-reinforced plastics (Fiberglass-Reinforced Plastics, be called for short FRP) have plurality of advantages such as intensity height, coefficient of thermal conductivity are low, corrosion resistance and good, early in the early 1990s, the FRP wall connecting piece has had certain Research And Engineering application in American-European, Japan.The FRP connector can effectively reduce cold (heat) bridge effect of body of wall at the connector position, effectively reduces the thermal transmittance of body of wall, improves the body of wall safety in utilization.But at present also there are some shortcomings in external existing FRP connector, mostly adopts bar-shapedly as the connector form, and shear resistance is relatively poor; The general employing of connector and body of wall anchorage style vertically is provided with fin and opens two kinds of anchor slots in part body both sides at the junction plate face, and form is comparatively single and anchoring property is relatively poor; The groove angle that is used to strengthen mechanical snap power between connector and the concrete slab and offers is less, also causes anchoring property relatively poor; It is medium that connector only can be applicable to the heat-preserving wall of thinner thickness ectonexine concrete slab.At present, the building industry of China develops to energy-conservationization, industrialization direction, and the prefabricated connecting member of compound wall body of development and application structure and function integration has important society, economy and environmental benefit.
The utility model content
The purpose of this utility model is to provide that a kind of anchoring property is good, coefficient of thermal conductivity is low, corrosion resistance is good, construction is convenient, can be used for the connecting member of compound wall body than the thick-layer concrete slab.
For achieving the above object, the utility model adopts following technical scheme: a kind of connecting member of compound wall body, it is characterized in that: by the FRP plate, the FRP joint bar and the ABS plastic collar are formed, wherein the bottom of FRP plate is the shape of the angle of wedge, symmetry vertical groove is in opposite directions arranged on the two sides of FRP plate, the both sides of vertical groove are fin, described FRP joint bar has two at least, be inserted in respectively in the vertical groove of the epimere of FRP plate and hypomere, the described ABS plastic collar is enclosed within the stage casing of FRP plate, the ABS plastic collar is made up of cover ring body and the collar cap that is positioned at cover ring body upper end, the inside wall of cover ring body is corresponding with the section configuration of FRP plate, and the lateral wall of cover ring body is a matsurface.
The epimere of described FFRP plate and hypomere all have circular hole, and described FRP joint bar is through in the circular hole and with the FRP plate fixedlys connected.
Described matsurface can be screw thread or convex-concave point.
Compared with prior art the utlity model has following characteristics and beneficial effect:
Characteristics such as 1, the utility model has been realized a kind of novel prefabricated heat preservation wall body connector that integrates body of wall carrying and heat insulation function, and it is effective to adopt the body of wall of this connector to have an integral heat insulation, and good endurance, speed of application are fast.
2, because the moment of inertia that connector is walked around the variant direction of centroid point has nothing in common with each other, the connector plane is provided with direction there is considerable influence in the stress performance of connector.Test shows: because the moment of inertia of the strong axle of connector cross section is bigger, has higher shear-carrying capacity when being provided with than the vertical shear direction when connector plane parallel shearing direction is provided with and antiskid moves rigidity, therefore by the connector ratio of two kinds of directions rationally is set, can improve the stress performance of body of wall.
3, owing to only pass through FRP connector drawknot between the inner, external wall sheet, thermal technology's weak part of novel prefabricated combined wall significantly reduces than the combined wall of the metal system of employing connector, the thermal transmittance of body of wall is less, and the phenomenon of conventional composite body of wall inner surface dewfall can not occur.
4, the utility model is applicable to the structure-function integration prefabricated heat preservation wall body, has advantages such as anchoring property is good, coefficient of thermal conductivity is low, corrosion resistance is good, easy construction, has comparatively wide application prospect in field of civil engineering.
