Abstract

The utility model discloses a novel prefabricated composite reinforced concrete wall board member, belongs to the field of earthquake resistance of engineering structures and is mainly applied to rural low-rise residential structures at earthquake areas. Particularly, the novel prefabricated composite reinforced concrete wall board member is a composite building board which integrates structural earthquake resistance, thermal insulation and heat insulation. The novel prefabricated composite reinforced concrete wall board member comprises a concrete layer and a middle sandwich layer, and is characterized in that a reinforcement net rack is of a three-dimensional spatial structure, i.e., reinforcement meshes on the two sides are connected by obliquely inserted reinforcements in a bidirectional three-dimensional cross mode. The novel prefabricated composite reinforced concrete wall board member has the advantages that the construction stressing performance is improved. The specific performance is that the novel prefabricated composite reinforced concrete wall board is constructed in the three-dimensional spatial reinforcement net rack mode, the longitudinal connection of the steel truss connector only on the board of the conventional composite board is changed, the reinforcement meshes on the two sides are connected by the obliquely inserted reinforcements in the bidirectional three-dimensional cross mode, meanwhile, the reinforcement ratio of the reinforcement fabrics on the two sides is increased, and the strength and the thickness of the concrete layer are improved so as to realize good construction stressing performance.

Description

Novel prefabricated composite reinforcing steel bar concrete wall board member

Technical field

The utility model belongs to engineering structures antidetonation field, is mainly used in rural area, earthquake zone low story dwelling structure, and specifically, novel prefabricated composite reinforcing steel bar concrete wall board member is the building composite board that a kind of structure set antidetonation, thermal insulation are integrated.

background technology:

explanation of nouns:3D plate is commonly called as " sandwich boards ", to be formed by the additional cold drawn wire in polystyrene central layer both sides and concrete or cement mortar, middle by oblique steel wire, intert a kind of compound sandwich sheet material fixedly forming, there is, quick construction good from heavy and light, thermal insulation, sound insulation, fireproof performance, the plurality of advantages such as cheap.

At present, the 3D plate of domestic production consists of steel wire net rack and cement mortar substantially, generally as non-structural element, is used for partition wall system, is of limited application.The problem of 3D plate in application mainly contains:

structure tension performance is poor:longitudinal oblique cutting ,Wei Yu both sides steel wire net rack node that 3D plate oblique inserted wire only limits to plate forms triangle, and structural integrity is not strong, poor stability.And 3D plate adopts steel wire net rack and cement mortar to form more, structure tension performance is poor, can only be used as non-structural element, is of limited application.

construction problem is more, affects construction quality:the half Prefabrication mode that 3D plate adopts easily occurs such as central layer and steel wire net rack distortion is excessive, steel wire net rack is too intensive, paving is smeared cement mortar difficulty when paving is smeared cement mortar in work progress; After body of wall moulding, easily ftracture; Part 3D plate adopts while spraying mortar or concrete construction, sprays rebound degree and crosses the problems such as high.

Utility model content

Problem for 3D plate in applying, novel prefabricated composite reinforcing steel bar concrete panel has carried out following improvement:

Novel prefabricated composite reinforcing steel bar concrete panel comprises layer of concrete and therebetween sandwich layer, it is characterized in that: bar frame is three dimensions structure, and oblique cutting reinforcing bar connects the steel mesh reinforcement of both sides in two-way clover leaf mode.

Described therebetween sandwich layer is prefabricated thermal insulation material.

Described prefabricated thermal insulation material is a kind of in polystyrene board, phenolic foam board.

Described therebetween sandwich layer is cast-in-situ thermal-insulated material.

The steel bar preassembling of described layer of concrete leaves anchorage length.

The utility model has the advantage of: (1) improves structure tension performance.Be in particular in: novel prefabricated composite reinforcing steel bar concrete panel adopts three dimensions bar frame make, change traditional 3D plate oblique inserted wire only in longitudinal connection of plate, by the two-way graded crossing mode of oblique cutting reinforcing bar, both sides steel mesh reinforcement is connected, increase both sides steel mesh reinforcement reinforcement ratio simultaneously and improve layer of concrete intensity and thickness, thereby thering is good structure tension performance.

(2) change construction technology, improve construction quality: the half Prefabrication mode adopting for 3D plate, in work progress, easily occur that steel wire net rack distortion is excessive, paving smears after cement mortar difficulty, body of wall moulding easily problems of crack, the form of construction work that novel prefabricated composite reinforcing steel bar concrete panel adopts complete prefabricated suitability for industrialized production, site assembly to connect, be convenient to control of product quality, improve efficiency of construction and construction quality; In addition, it is by connection measures such as employing cast-in-situ concrete constructional column, collar tie beams, prefabricated panel to be assembled that the agriculture of novel prefabricated composite reinforcing steel bar concrete panel occupies structure, has improved the anti-seismic performance in house.

The specific embodiment

According to the difference of member therebetween sandwich layer, novel prefabricated composite reinforcing steel bar concrete wall board member mainly contains following two kinds and manufactures mode:

specific embodiment 1:

When novel prefabricated composite reinforcing steel bar concrete wall board member adopts prefabricated thermal insulation materials such as polystyrene board 1, phenolic foam board, its manufacturing process is as follows:

1), according to member designs size, cut intermediate layer sandwiched plate;

2), according to design and sandwiched plate both sides, code requirement , intermediate layer, arrange steel mesh reinforcement, bar diameter size and spacing should be carried out corresponding calculating according to standard in conjunction with Practical Project, for example, adopt the Double Faces to Install Φ 4 200, reinforcement ratio 0.17%;

3), by oblique cutting muscle 2, oblique cutting muscle diameter, spacing adopt according to design and code requirement, for example, adopt Φ 4@200, press plum blossom-shaped layout, two-way graded crossing mode connects both sides steel mesh reinforcement;

4), in polystyrene board both sides concreting 3 respectively, concrete strength and thickness adopt by design and code requirement, complete structure manufacture and are carried out in accordance with regulations maintenance.

specific embodiment 2:

When novel prefabricated composite reinforcing steel bar concrete wall board member adopts such as cast-in-situ thermal-insulated materials such as vitrified micro-bead heat preserving slurries, its manufacturing process is as follows:

1), according to design and code requirement, make bar frame, comprising: both sides steel mesh reinforcement and oblique cutting muscle;

2), the usage level platform that vibrates keeps flat component template, first builds bottom concrete, next build in the middle of sandwich insulating layer, finally build layer concrete, complete structure manufacture and be carried out in accordance with regulations maintenance.

3), mode two bar diameter, spacing and the layer of concrete intensity, the thickness equivalent way one that adopt, this does not repeat.

Special instruction: novel prefabricated composite reinforcing steel bar concrete wall board member carries out when prefabricated, layer of concrete reinforcing bar need be according to designing requirement, reserved corresponding anchorage length.
