Description
Technical field
The invention belongs to technical field of civil engineering, be specifically related to a kind of prefabricated heat preservation wall body.
Background technology
China's gross floor area is with the speed increase in every year 15%～20%, and the energy that building directly consumes in construction and use accounts for more than 30% of the total power consumption of the whole society, and be the continuation ascendant trend, in country and the local Eleventh Five-Year Plan construction plan all with building energy conservation as main energy-conservation construction object it.In this complicated system engineering of building energy conservation, enclosed structure is energy-conservation to be this system engineering most important parts.
As main building maintenance structure,, there is weak point equally though existing prefabricated heat preservation wall body has better thermal property than traditional homogenous material body of wall.The heat-preserving wall connector of domestic-developed adopts the metal lattice work muscle usually, easily produces cold and hot bridge at connecting portion, reduces the wall thermal insulating effect; Metal dowel corrosion resistance and poor durability make body of wall in use cause potential potential safety hazard.Though the prefabricated heat preservation wall body of part exploitation is abroad arranged, its connector adopts fibre reinforced plastics to come the substituted metal material to reduce cold and hot bridge effect, improve the corrosion resistance and the durability of connector, but connector adopts same direction to arrange in body of wall, make connector can not give full play to its stress performance in wall plane two directions, and inside and outside two concrete panels of body of wall do not have other construction measure in the end, in use easily make two walls produce changing of the relative positions slit in the end, make moisture infiltrate the middle EPS insulation layer of body of wall and reduce its heat insulation effect.
Summary of the invention
The object of the present invention is to provide that a kind of thermal transmittance is low, heat insulation property and corrosion resistance is good, speed of application is fast prefabricated heat preservation wall body.
The prefabricated heat preservation wall body that the present invention proposes, form by insulation layer 2, concrete inner wall panel 3, concrete external wall panel 4 and FRP connector, be provided with interior vertically layout of inner wall panel in the concrete inner wall panel 3 and be provided with the interior vertical lateral arrangement reinforcing bar 8 in reinforcing bar 7 and the side fascia of arranging of side fascia in reinforcing bar 5 and the inner wall panel in lateral arrangement reinforcing bar 6, the concrete external wall panel 4, the FRP connector is " worker " font structure, form by the web 9 and the edge of a wing 10, the edge of a wing 10 has two, lays respectively at web 9 two ends; Insulation layer 2 is provided with hole slot in the insulation layer 2 between concrete inner wall panel 3 and concrete external wall panel 4, hole slot adopts and is criss-cross arranged, and the FRP connector inserts in this hole slot; The end of heat-preserving wall is provided with dowel 12, and this dowel 12 is U type structure, and insert respectively in concrete external wall panel 4 and the concrete inner wall panel 3 at the two ends of this dowel 12.
Among the present invention, the end of concrete inner wall panel 3 and concrete external wall panel is provided with XPS froth bed 11.
Among the present invention, two adjacent heat-preserving wall correspondences have semi-circular recesses, and rod 14 is set in the semi-circular recesses, and all the other positions of heat-preserving wall end connect by waterproof and sealing material layer 13.
Among the present invention, two edges of a wing 10 are anchored in respectively in concrete inner wall panel 3 and the concrete external wall panel 4.
Among the present invention, described insulation layer 2 adopts the EPS insulation layer.
Among the present invention, described rod 14 adopts polystyrene material.
Lay internal layer concrete wall template when the present invention constructs earlier, and lay the vertical and horizontal layout reinforcing bar of outer body of wall, build the outer concrete side fascia to outer thickness of wall body; Lay insulation layer 2 then above it, insulation layer 2 should be offered the connector hole slot of the interlaced arrangement of prior location, and the area of offering hole slot should be slightly larger than the edge of a wing area of " worker " font connector; Heat insulating block is filled in gap on connector two coxostermums and the edge of a wing, and the FRP connector is inserted the default hole slot place of insulation layer; On insulation layer 2, lay internal layer concrete wall reinforcing bar and concreting to the position.
Can both give full play to its stress performance for making wall connecting piece at both direction, connector adopts and is criss-cross arranged in wall insulating layer, insulation layer is reserved the connector hole slot that is criss-cross arranged of location in advance, hole slot punches and should be slightly larger than the connector outside dimension, so that arrange " worker " font connector.Crisscross spacing is decided by the anchoring strength of connector and both sides concrete panel and the stressed size of prefabricated heat preservation wall body.
The relative changing of the relative positions that causes in plane external load effect and " thermal flexure " effect of producing owing to the indoor and outdoor temperature difference in the body of wall end for fear of the ectonexine body of wall, strengthen the mass action of body of wall edge ectonexine concrete panel, between the ectonexine concrete slab at body of wall edge, connect U fiber type reinforced plastic dowel.
When two bodies of wall connect, be reserved with semi-circular recesses, place the water proof type rod in it, block with the slit of waterproof and sealing material two walls in the rod outside in the outside concrete panel end of every body of wall.Prevent that outside rainwater from infiltrating body of wall inside.
Beneficial effect of the present invention is:
(1) the present invention adopts " worker " font FRP connector to connect, and web bears moment of flexure effect outside horizontal shear and the plane in the wall plane, and the edge of a wing is anchored in to play in the concrete slab and prevents that two bodies of wall from peeling off the effect of raising integrality of wall.In order to prevent that the edge of a wing from connecting the root fracture in web, variable cross-section is adopted on the edge of a wing, increases edge of a wing root area.
(2) FRP connector of the present invention in body of wall arrangement for being criss-cross arranged.Body of wall is subjected to plane external load (wind load and seismic load) to do the time spent, and connector is subjected to the curved scissors compound action and since connector at the cross section inertia of the centre of form two direction of principal axis apart from difference, the connector plane is provided with direction there is considerable influence in the stress performance of connector.Test shows that the connector that is criss-cross arranged can be given full play to its stress performance, and the levels concrete panel is very little in the slippage of both direction and connector, and this arrangement can improve the holistic resistant behavior of body of wall.
(3) U fiber type reinforced plastic dowel is adopted in the body of wall end, strengthens the mass action of body of wall edge ectonexine concrete panel, avoids in the body of wall end in plane external load effect and because " heat is bent " effect that the indoor and outdoor temperature difference produces produces the changing of the relative positions.
(4) the present invention " worker " font FRP connector and U fiber type reinforced plastic dowel have reduced the thermal transmittance of body of wall, realized a kind of novel prefabricated enclosed structure that integrates body of wall carrying and heat insulation function, it is effective that this body of wall has integral heat insulation, characteristics such as good endurance, speed of application are fast.Simultaneously, connect material, make its weight reduction, reduce the foundation construction expense of building owing to use fibre reinforced plastics to substitute conventional metals.
