Description
Technical field
The utility model belongs to construction engineering technical field, is specifically related to a kind of prefabricated sandwich wall fibre reinforced plastics connector.
Background technology
China's tradition materials for wall is main with small-sized bulk materials such as loam brick, building-blocks, has many deficiencies such as dead load is excessive, speed of application is slow, work efficiency is low, construction quality instability.Shortcomings such as in recent years, it is the building heat insulation system of insulation component that China progressively begins in building to adopt with the organic foam material, but also exists construction comparatively complicated, and fireproof performance is relatively poor, and be unfavorable for the sustainable development of builing industry.At present, the building industry of China develops to energy-conservationization, industrialization direction, and the prefabricated sandwich wall system of development and application structure and function integration has important society, economy and environmental benefit.
As the key member of prefabricated heat preservation wall body, the main effect of connector is the longitudinal shear between effect and body of wall that starts between two concrete slabs of opposing, and the form of connector should take into full account the double action of power transmission and insulation.Existing prefabricated sandwich wall adopts the metal lattice work muscle to connect mostly, is prone to produce heat bridge at the connector position, and possibly cause potential potential safety hazard because of the connector corrosion.Fibre reinforced plastics are as a kind of nonmetal high performance material, and its coefficient of thermal conductivity is significantly less than steel and concrete material, adopt fibre reinforced plastics to make the heat-preserving wall connector and can reduce wall heat transfer coefficient effectively.
In sum, develop that a kind of coefficient of thermal conductivity is low, corrosion resistance good, the prefabricated easily sandwich wall fibre reinforced plastics of installation connector is those skilled in the art's a goal in research.
The utility model content
The purpose of the utility model is that a kind of high-strength light is provided, coefficient of thermal conductivity is low, corrosion resistance good, the prefabricated sandwich wall fibre reinforced plastics connector of easy construction.
The prefabricated sandwich wall fibre reinforced plastics connector that the utility model proposes; Form by the fibre reinforced plastics junction plate 10 and the engineering plastics collar 11; Fibre reinforced plastics junction plate 10 middle parts are provided with longitudinal fluting 1, and the edge is provided with fin 3, and two ends are provided with anchoring notch 2; The engineering plastics collar 11 is made up of collar cap 4, cover ring body 5 and thread belt 6, and collar cap 4 is positioned at cover ring body 5 ends, and thread belt 6 is positioned on the cover ring body 5; The fibre reinforced plastics junction plate inserts in the engineering plastics collar 11, and the engineering plastics collar 11 centers on and be fixed in fibre reinforced plastics junction plate 10 middle parts; The anchoring notch 1 at fibre reinforced plastics junction plate 10 two ends is positioned at the engineering plastics collar 11 outsides.
In the utility model, anchoring notch 1 can be single row or multiple rows, and its number and the degree of depth are looked connector anchorage zone length and decided.
In the utility model, thread belt 6 surfaces can be screw thread or irregular convex-concave zone.
In the utility model, said fibre reinforced plastics junction plate adopts pultrude process to make, and raw material is E glass fiber and unsaturated polyester resin, the shop layer should comprise unidirectional rove, continuous fiber felt and ± 45 degree multiaxises are to cloth, shop layer symmetry laid.For guaranteeing that connector has higher shear strength, ± 45 ° of multiaxises should be not less than 35% of gross thickness to the shop of cloth layer thickness, and the design fiber volume fraction is not less than 50%.Behind the fibre reinforced plastics junction plate product moulding, process the FPR junction plate through fixed length cutting.Adopt machining equipment to go out the anchoring notch in the junction plate end cut subsequently, the anchoring notch should avoid occurring sharp corners.Adopt Shooting Technique to utilize pressure to annotate between the plastic products mould and fibre reinforced plastics junction plate in the engineering plastics of fusion at last, obtain prefabricated sandwich wall fibre reinforced plastics connector finished product after the cooling.
Because fibre reinforced plastics pultrusion connector surface is comparatively smooth; The anchored force of connector is mainly from the mechanical snap effect between connector notch and the concrete; Snap-in force produces owing to groove is embedded in concrete; The connector notch can produce very big mechanical snap power to concrete extruding such as same wedge.
The beneficial effect of the utility model is:
Characteristics such as (1) the utility model has been realized a kind ofly integrating that body of wall carries and the novel connected system of heat insulation function, and it is effective 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 through 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 fibre reinforced plastics connector and fiber reinforced plastic rod drawknot between the inner, external wall sheet; Thermal technology's weak part of novel prefabricated heat preservation wall body is than the heat preservation composite wall much less of the metal system of employing connector; The thermal transmittance of novel wall is less, and the phenomenon of traditional heat-preserving wall inner surface dewfall can not occur.
