Abstract
The invention belongs to the technical field of civil engineering, and concretely relates to an FRP connecting piece of a prefabricated heat preservation wall body. The connecting piece consists of an FRP connection board and a plastic socket ring and is characterized in that the FRP connection board is fabricated by a pultrusion technique, a fiber layering is compositely laid by adopting unidirectional coarse roving, continuous fibrofelt and positive/negative degree multiple axial directional cloth. After pultrusion, the FRP connection board is cut by fixed length to fabricate an FRP connection board single piece, and mechanical processing equipment is used for cutting one or more than one anchoring rabbet at the end part of the connection board, and finally the melt ABS plastic is cast around the FRP connection board by a casting technique to obtain the finished product of the FRP connecting piece of the prefabricated heat preservation wall body; wherein, the connection board component in the connecting piece is used for connecting the concrete wall pieces at the two sides of a heat preservation board, while the ABS plastic socket ring is used for fixing the position of the connecting piece during concrete casting. The invention realizes a novel connecting system with an integral structural function, has the advantages of low heat conductivity coefficient, good corrosive nature, simple and convenient construction and the like, and has relatively extensive application prospect in the field of civil engineering.
Description
Technical field
The invention belongs to construction engineering technical field, be specifically related to a kind of prefabricated heat preservation wall body FRP (fibre reinforced plastics) connector.
Background technology
There are many deficiencies such as dead load is excessive, speed of application is slow, work efficiency is low, construction quality instability in China's tradition materials for wall based on small-sized bulk materials such as loam brick, building-blocks.With the building that traditional materials for wall is built, its energy consumption is about 3 times of the close developed country of weather.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, in this system organic foam material mostly attached to retaining wall on, construction is comparatively complicated, fireproof performance is relatively poor, and is unfavorable for the sustainable development of builing industry.At present, the building industry of China develops to energy-conservationization, industrialization direction, and the prefabricated heat preservation 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 starting the longitudinal shear between effect and body of wall 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 heat preservation wall body (as the EVG-3D wallboard of Austrian EVG company exploitation) adopts the metal lattice work muscle to connect mostly, easily produces heat bridge at the connector position, and may 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 1/150 of steel, are 1/30 of concrete materials, adopt FRP 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, installation easily FRP connecting piece of prefabricated heat preservation wall body be those skilled in the art's goal in research.
Summary of the invention
The object of the present invention is to provide a kind of high-strength light, coefficient of thermal conductivity is low, corrosion resistance good, the FRP connecting piece of prefabricated heat preservation wall body of easy construction.
The FRP connecting piece of prefabricated heat preservation wall body that the present invention proposes is made up of the FRP junction plate 10 and the collar 11, and FRP 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 1; The 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 FRP junction plate inserts in the collar 11, and the collar 11 centers on and be fixed in FRP junction plate 10 middle parts; The anchoring notch 1 at FRP junction plate 10 two ends is positioned at the collar 11 outsides.
Among the present invention, anchoring notch 1 can be single row or multiple rows, and its number and the degree of depth are decided on connector anchorage zone length.
Among the present invention, thread belt 6 surfaces can be screw thread or irregular convex-concave zone.
Among the present invention, described FRP junction plate adopts pultrude process to make, and raw material is E glass fiber and unsaturated polyester resin, and the shop layer should comprise unidirectional rove, continuous fiber felt and soil 45 degree multiaxises to cloth, and 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 FRP junction plate product moulding, make 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 FRP junction plate the ABS plastic of fusion at last, obtain the FRP connecting piece of prefabricated heat preservation wall body finished product after the cooling.
Because FRP 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.
Beneficial effect of the present invention is:
Characteristics such as (1) the present invention has realized a kind of novel connected system that integrates body of wall carrying and 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 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 and FRP muscle 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.
