Description

A kind of precast concrete wall

Technical field

The invention belongs to prefabricated reinforced concrete structure component technology field, particularly relate to one and be applicable to assembled integral The precast concrete wall of structure.

Background technology

Buildings exterior-protected structure dispersed heat accounts for building about the 40% of overall heat consumption, therefore should strengthen building enclosure Energy-efficient performance.For improving the heat-insulating property of body of wall, typically use combined wall, will load-bearing reinforced concrete wall and energy-saving material It is combined with each other, has inner thermal-insulation compounds wall, external heat insulating composite wall and sandwich heat preserving wall body three kinds.Sandwich heat preserving wall body includes Inner wall, exterior wall and be arranged at centre heat-insulation material, insulation material can be durable from the destruction of outside environmental elements Property is good.For improving building industrialization level, use prefabricated sandwich heat preserving wall body.In prior art, prefabricated sandwich heat preserving wall body is prefabricated There is the problem that globality is poor in the connection between unit.

Summary of the invention

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

For reaching above-mentioned purpose, the present invention provides a kind of precast concrete wall, and this body of wall includes first be arranged in parallel Precast concrete wall panel and the second precast concrete wall panel, use wet connection between described first precast concrete wall panel, and described the Involvement is used to connect between two precast concrete wall panels.So-called involvement connects, the connected mode of the most dry operation, passes through between prefabricated panel On wallboard, pre-embedded steel slab or other steel parts, be bolted or weld, and reaches the purpose connected;So-called wet connection, i.e. The connected mode of wet trade, during connection, between prefabricated panel, wallboard is linked together by casting concrete or cement mortar.First is pre- Concrete panel processed and the thickness of the second precast concrete wall panel and arrangement of reinforcement etc. are according to stress demand, use demand and construction demand Etc. determining.

Method of attachment between described first precast concrete wall panel is: the first precast concrete wall panel has in seam both sides Transverse concave groove, the two sides of transverse concave groove are connected with reinforcing bar, described reinforcing bar hang with reinforced steel bar ring;Adjacent first precast concrete wall panel Between reinforced steel bar ring mutually join, reserve certain handing-over space therebetween;In wallboard side and transverse concave groove, casting concrete will First precast concrete wall panel connects together.Transverse concave groove and connect transverse concave groove two sides reinforcing bar can improve prefabricated panel with The globality of pouring concrete after between wallboard.Reinforced steel bar ring hangs over prefabricated panel side, can freely adjust position on vertical muscle, convenient Precast reinforced concrete structure transport, lifting, facilitate reinforced steel bar ring to position, and reinforced steel bar ring replaces the stirrup that job site is arranged simultaneously Deng, reduce job site steel project.In order to improve connection integrity, the reinforced steel bar ring between the first precast concrete wall panel Handing-over space is inserted into vertical muscle, forms framework of steel 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..When using closed stirrup, can make at prefabricated panel Cheng Houzai installs, i.e. by the gap at closed stirrup crotch through vertical muscle.

Described second precast concrete wall panel side is embedded with steel plate, Plate Welding between adjacent wall board or be bolted to Together.In order to prevent rainwater etc. from invading precast concrete wall, between described second precast concrete wall panel, waterproof sealing is set Material.

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

Between described first precast concrete wall panel and the second precast concrete wall panel, waterproof layer is set.Or described first Heat-insulation layer and waterproof layer are set between precast concrete wall panel and the second precast concrete wall panel simultaneously.

It is connected with connector between described first precast concrete wall panel and the second precast concrete wall panel.Connector is by first Precast concrete wall panel and the second precast concrete wall panel connect together.Described connector can be fiber-reinforced composite material rib or Fiber reinforced composite section bars (such as i shaped cross section section bar) or fibre reinforced composites truss, connector two ends are respectively Anchor into the first precast concrete wall panel and the second precast concrete wall panel.

Vertical abutment joint between described first precast concrete wall panel and the vertical abutment joint between the second precast concrete wall panel it Between distance be 200mm.At the vertical abutment joint poured between the first precast concrete wall panel during concrete, the second precast concrete Wallboard can support seam crossing template, or the side template directly as seam crossing.

The present invention can be used in the body of wall of shear wall structure, frame shear wall structure etc. it can also be used to basement wall In, and in other bodies of wall.The precast concrete wall of the present invention can horizontal positioned as floor member, such as there being guarantor The roof boarding of the requirement such as warm, waterproof, now arrangement of reinforcement etc. according to floor stress, use demand.

The present invention compared with prior art has the advantage that.

Structure sheaf, maintenance level and heat-insulation layer etc. are combined by the precast concrete wall of the present invention, industrialized level High.

First precast concrete wall panel and second precast concrete wall panel of the precast concrete wall of the present invention have respectively Different functions, the i.e. first precast concrete wall panel is linked together by wet connection, mainly ensures precast concrete wall Globality so that precast concrete wall has enough rigidity and bearing capacity;Second precast concrete wall panel is mainly Maintenance effect, it is ensured that heat-insulation layer etc. are not by environmental injury.

Hanging with reinforced steel bar ring in the precast concrete wall of the present invention, reinforced steel bar ring is hinged on prefabricated panel, can be at certain model Enclose and interior freely adjust position, facilitate the bar connecting etc. between the transport of precast reinforced concrete structure, installation and prefabricated components.

The precast concrete wall of the present invention can improve the industrialized level of precast concrete.Existing concrete Soil component side reserved steel bar, job site is reconfigured at reinforcing bar to the connection realizing between prefabricated components on reserved steel bar;This Reinforced steel bar ring in bright can replace the reinforcing bar that in prior art, job site configures on reserved steel bar, reduces job site reinforcing bar and joins Put quantity, the part reinforced bar engineering of job site is transferred to factory, improve building industrialization level.
