Description
Technical field
The utility model belongs to the pre-cast building technical field, is specifically related to the concrete sandwich boards and constructs with connector.Be used for the production of concrete heat-insulating sandwich boards.
Background technology
At present, the exterior wall of assembled architecture the most reasonably way is to adopt the concrete sandwich boards, it is made up of surperficial coagulation scholar layer, insulation layer and structural concrete layer, when producing the concrete sandwich boards, need to adopt connector, the three-layer structure of plate is linked together, and known connector is to adopt the concrete rib connector or adopt rebar connector, the nonmetal connector that also has some to adopt the injection moulding mode to produce.But because the unreasonable and concrete anchoring property of its end structure does not reach designing requirement.
The utility model content
The purpose of this utility model is for overcoming the weak point of existing connector, design a kind of connector for the concrete sandwich boards, the utlity model has the intensity height, anchoring property is strong, thermal insulation good, the characteristics of good corrosion resistance, easy construction, has comparatively wide application prospect in field of civil engineering.
The connector that is used for the concrete sandwich boards of the utility model design, it is characterized in that, mainly by forming with the long rod in the pillar center of a plurality of axial fins and the location big envelope that is placed in this length rod periphery, the two ends of the long rod in its center are respectively equipped with the groove of wedge-like to this connector;
Cross section of the long rod in this center is a kind of of the periphery of different-diameter circle, ellipse or polygon that a plurality of radially fins are arranged; These a plurality of fins can be two, three or four.
The length of the long rod in this center is 150mm-220mm.
The smallest cross-sectional place center circle diameter of the long excellent groove in this center is greater than 5mm.
The location big envelope outer surface that this location big envelope mainly constitutes by the fixed aunular sheet of the upper end that connects successively, by upper smooth face, middle part matsurface and lower step shape anchorage zone, this big envelope center, location has a through hole, and the shape of this through hole is corresponding with the section configuration of the long rod in center.
The cross section of this location big envelope is circular, and location big envelope appearance matsurface is by arranging equidistantly that every the oblique miter angle of 3mm circular salient point or equidistant screw thread constitute salient point or flight pitch 2-4mm.
The utility model connector has following remarkable advantage:
1, because connector is pillar, when producing, installs easily the concrete sandwich boards, and little to the concrete strength influence behind the insertion concrete.
2, because connector is the long rod in a band fin circular cross-section center, core of section lifting surface area diameter is greater than 5mm, when plate is installed rear connectors and is subjected to curved scissors than a lot of with the good rigidity of the pole of area, square rod.
3, the groove at connector two ends can use that cutting technique is convenient to be formed, anchor into concrete slab after because the suction-operated of groove, can reliable earth anchor in the bottom concrete.
4, the wedge-shaped indentation of a plurality of fins can increase and the snap-in force of burying layer concrete underground, and the anchoring of connector in concrete can be born bigger pulling force when plate is subjected to perpendicular to the plate area load.
5, the material of connector can be the glass fiber through the moulding of extruding drawing process, Materials with High Strength through the formation of resin corrosion-resistance treatment, alternative metal and engineering plastics effectively link together the concrete of insulation layer both sides, and since the setting of fibrous glass insulation good (coefficient of thermal conductivity is very little) connector not can the time plate produce heat bridge, make and adopt the sandwich boards of the utility model connector to improve greatly than the heat-insulating property of the sandwich boards of sandwich boards with ribbing, metal connecting piece or engineering plastics connector.
