Description

A kind of precast concrete body of wall

Technical field

The invention belongs to prefabricated reinforced concrete structure component technology field, relate in particular to a kind of precast concrete body of wall that is applicable to cast in place and precast construction.

Background technology

Buildings exterior-protected structure dispersed heat accounts for 40% left and right of building overall heat consumption, therefore should strengthen the energy-efficient performance of space enclosing structure.For improving the heat-insulating property of body of wall, generally adopt combined wall, be combined with each other by load-bearing reinforced concrete wall and energy-saving material, there are three kinds of inner thermal-insulation compounds wall, external heat insulating composite wall and sandwich heat preserving wall bodies.Sandwich heat preserving wall body comprise inner wall, exterior wall and be arranged in the middle of heat-insulation material, heat insulating material can be avoided the destruction of external environment factor, good endurance.For improving industrialization of construction industry level, adopt prefabricated sandwich heat preserving wall body.There is the poor problem of globality in the connection in prior art between prefabricated sandwich heat preserving wall body prefabricated unit.

Summary of the invention

The invention provides a kind of precast concrete body of wall, facilitate installation and the wall connecting of prefabricated sandwich heat preserving wall body, guarantee body of wall globality, improve building structure industrialized level.

For achieving the above object, the invention provides a kind of precast concrete body of wall, this body of wall comprises the first precast concrete panel and the second precast concrete panel that be arranged in parallel, adopts wet connection between described the first precast concrete panel, between described the second precast concrete panel, adopts involvement to connect.So-called involvement connects, i.e. the connected mode of dry operation, by pre-embedded steel slab or other steel parts on wallboard, is bolted or welds between prefabricated panel, reaches the object of connection; So-called wet connection, i.e. the connected mode of wet trade, when connection, between prefabricated panel, concreting or cement paste link together wallboard.Thickness and the arrangement of reinforcement etc. of the first precast concrete panel and the second precast concrete panel determined according to stressed demand, user demand and construction demand etc.

Method of attachment between described the first precast concrete panel is: the first precast concrete panel has transverse concave groove in seam both sides, and the two sides of transverse concave groove are connected with reinforcing bar, on described reinforcing bar, hangs with reinforced steel bar ring; Reinforced steel bar ring between adjacent the first precast concrete panel joins mutually, therebetween reserved certain handing-over space; In wallboard side and transverse concave groove, concreting connects together the first precast concrete panel.The globality of pouring concrete after transverse concave groove can improve between prefabricated panel and wallboard with the reinforcing bar that is connected transverse concave groove two sides.Reinforced steel bar ring hangs over prefabricated panel side, can on vertical muscle, freely adjust position, facilitates precast reinforced concrete structure to transport, lift, and facilitates reinforced steel bar ring location, and reinforced steel bar ring replaces the stirrup of job site setting etc., minimizing job site steel project simultaneously.In order to improve connection integrity, in the handing-over space of the reinforced steel bar ring between the first precast concrete panel, insert vertical muscle, form cage of reinforcement with reinforced steel bar ring.Described reinforced steel bar ring is welded reinforcement ring, or closed stirrup, or the reinforcing bar of other shapes.Reinforced steel bar ring can be rectangle, circle etc.In the time adopting closed stirrup, can after completing, prefabricated panel install again, pass vertical muscle by the gap at closed stirrup crotch place.

Described the second precast concrete panel side is embedded with steel plate, and Plate Welding or bolt between adjacent wall board link together.In order to prevent the intrusion precast concrete bodies of wall such as rainwater, between described the second precast concrete panel, waterproof and sealing material is set.

Between described the first precast concrete panel and the second precast concrete panel, insulation layer is set, guarantees the heat-insulating property of precast concrete body of wall.Described insulation layer can adopt EPS insulation layer, perlite products, polyurethane on-the-spot foam etc.

Between described the first precast concrete panel and the second precast concrete panel, waterproofing course is set.Or between described the first precast concrete panel and the second precast concrete panel, insulation layer and waterproofing course are set simultaneously.

Between described the first precast concrete panel and the second precast concrete panel, be connected with connector.Connector connects together the first precast concrete panel and the second precast concrete panel.Described connector can be fiber-reinforced composite material rib or fiber reinforced composite section bars (for example i shaped cross section section bar) or fibre reinforced composites truss, and connector two ends anchor into respectively the first precast concrete panel and the second precast concrete panel.

Distance between vertical abutment joint between vertical abutment joint and the second precast concrete panel between described the first precast concrete panel is 200mm.When build between the first precast concrete panel vertical abutment joint place concrete time, the second precast concrete panel can support seam crossing template, or directly as a side template of seam crossing.

The present invention can be used for, in the body of wall of shear wall structure, frame shear wall structure etc., also can be used in basement wall, and in other bodies of wall.Precast concrete body of wall of the present invention can horizontal positioned as floor member, for example, as the roof panel that has insulation, waterproof etc. to require, now, the user demand stressed according to floor such as arrangement of reinforcement.

The present invention compared with prior art has following advantage.

Precast concrete body of wall of the present invention combines deck, maintenance level and insulation layer etc., and industrialized level is high.

The first precast concrete panel and second precast concrete panel of precast concrete body of wall of the present invention have respectively different functions, the first precast concrete panel links together by wet, be mainly the globality that guarantees precast concrete body of wall, thereby make precast concrete body of wall there is enough rigidity and bearing capacity; The second precast concrete panel is mainly maintenance effect, and assurance insulation layer etc. is not subject to environmental injury.

On precast concrete body of wall of the present invention, hang with reinforced steel bar ring, reinforced steel bar ring is hinged on prefabricated panel, can freely adjust within the specific limits position, facilitates reinforcing bar connection between transportation, installation and the prefabricated units of precast reinforced concrete structure etc.

Precast concrete body of wall of the present invention can improve the industrialized level of precast concrete.Existing precast unit side reserved steel bar, job site on reserved steel bar again configuration reinforcement realize the connection between prefabricated units; Reinforced steel bar ring in the present invention can replace the reinforcing bar that in prior art, job site configures on reserved steel bar, reduces job site reinforcing bar configuration quantity, and the part reinforced bar engineering of job site is transferred to factory, improves industrialization of construction industry level.
