Description
Technical field
The present invention relates to a kind of wall structure, especially a kind of precast spliced concrete slab wall body.
Background technology
At present, building masonry wall can be divided three classes with the different of form of construction work according to structure substantially: building block adds the mode of plastering, the mode of the on-the-spot splicing of prefabricated laminated parallel-plate and integrated poured mode.
The plaster major defect of mode of building block is that work progress is longer, but because easy construction, cost is not high, is wall construction mode main in the current building.But the body of wall globality that building block forms is bad, and insulation often is difficult to satisfactory to both parties with waterproof.
The major defect of prefabricated laminated parallel-plate is a complex structure, is applied to the external wall waterproof poor performance, and cost is high.
Though the body of wall that pouring type forms has good globality, cost is very high, and this cost has mainly comprised the cost and the concrete cost of material of form work engineering.Because the area of body of wall is bigger, the cost of form work engineering is considerable on the one hand.On the other hand,, then can cause the practicality of body of wall to reduce, be difficult to reach requirement like carry ability and endurance quality because of material strength problem if adopt light weight concrete construction for reducing cost of material.The body of wall cost of contrast building block mode, though the man-hour that pouring type needs in last cast operation is seldom, the cost of raw material and form work engineering is considerably beyond the whole cost of masonry way, this has caused the pouring type in the walling work to be difficult to promote.
Summary of the invention
The object of the present invention is to provide a kind of precast spliced concrete slab wall body, this body of wall has made full use of the quick of pouring type, has simplified form work engineering, has used light weight concrete construction in the structure.New wall structure not only can utilize the good thermal and insulating performance of light concrete, also can guarantee the usability and the durability of body of wall, can also reduce the building costs of body of wall.。
Technical scheme of the present invention is: a kind of precast spliced concrete slab wall body; This body of wall comprises inner, external wall panel and middle light weight concrete construction layer; Inside and outside metope uses precast concrete plank to be spliced, and is provided with cage of reinforcement in the middle of the light weight concrete construction layer, and cage of reinforcement is along the elongated layout of body of wall; And be connected with the load-carrying member at wall edge, cage of reinforcement upper edge short transverse is provided with horizontal steel wire at a certain distance; The inner surface of the precast concrete plank that shingle nail uses has a terrace with edge shape projection, from terrace with edge, passes the positioning wire that is parallel to plate face direction, and positioning wire is Chinese character pin-shaped arrangement, and positioning wire blocks formation with horizontal steel wire in the body of wall cage of reinforcement and is connected.
The edge of precast concrete plank is provided with the overlap joint eaves, convenient splicing.
The rough inner surface of precast concrete plank or have outstanding rib to strengthen bonding with layer of concrete.
Precast concrete plank can use the fibrous concrete material.
The invention has the advantages that: can satisfy the requirement of energy-conservation aspect, meet the policy of national wall reform.The surfaces externally and internally of body of wall uses prefabricated concrete slab to be spliced, and prefabricated concrete slab splicing is convenient, can play the effect of template during cast, and has saved the operation of dismounting template.The inner light weight concrete construction of body of wall can adopt cast-in-site or pumping mode, and work progress is time saving and energy saving.Integrality of wall is good.The averag density of body of wall is low, can reduce in the design process requirement to load-carrying members.The body of wall that adopts this mode to build, the cost of unit area can decrease.
The structure of body of wall (with reference to accompanying drawing 1) can be divided into three parts: the precast spliced concrete slab of cage of reinforcement, surfaces externally and internally, light weight concrete construction.
Reinforced concrete skeleton frame (with reference to accompanying drawing 2) plays fixing and interconnect function to whole body of wall, adopt diameter more than 6.5 millimeters reinforcing bar and the steel wire of diameter more than 3 millimeters process.Cage of reinforcement must be connected with the structure at body of wall two ends to guarantee the globality between body of wall and the structure.
Precast spliced concrete slab (with reference to accompanying drawing 3) constitutes two external surfaces of wall, when cast, plays the effect of template, after body of wall is accomplished, then becomes the primary structure part of body of wall.The thickness of prefabricated concrete slab adopts the concrete manufacturing of C20 and above grade more than or equal to 10 millimeters, is spliced to form metope through the overlap joint eaves between adjacent two plates.Clamping between the positioning wire that has through the steel wire that ties up in the cage of reinforcement structure and precast concrete plank itself can realize plate fixing on the metope normal direction, can the motion (with reference to accompanying drawing 5) of confinement plate on the metope direction through the splicing between the plate.Concrete slab can adopt the inner surface of coarse or form with ribbing, be used to strengthen and light weight concrete construction between cementitiousness.
Light weight concrete construction is the packing material of body of wall, adopts once or the gradation cast-in-place shaping.Invigoration effect is played to being connected between precast spliced concrete slab and the cage of reinforcement in light weight concrete construction sclerosis back, makes the various piece in the wall structure form an integral body.Though light weight concrete construction is not the major part in the body of wall use, can reach good heat insulation and defening effect.
The performance of body of wall and safeguard measure: thermal and insulating performance: owing to adopt light weight concrete construction to pour into a mould, the coefficient of thermal conductivity K of wall can reach national energy Saving Design of Residential Buildings standard less than 1.0.The density of body of wall: the interlayer of body of wall of the present invention has used light weight concrete construction; The averag density of body of wall is about 1/2nd of a common solid masonry panel; Can effectively reduce the load of conducting oneself with dignity corresponding to body of wall in the architectural design, reduce the cross section of the central load-carrying members of architectural design.The durability of body of wall: mainly refer to the resistant to rust ability of cage of reinforcement, this is mainly guaranteed by 2 aspects.At first be outer field concrete slab,, can treat as the topping in the building when thickness during greater than 15 millimeters.Secondly, light weight concrete construction forms the protection environment to cage of reinforcement.Integrality of wall: owing to adopted the cage of reinforcement that links to each other with bearing carrier, the overall performance of light weight concrete construction can be strengthened; And light weight concrete construction can play invigoration effect to concrete slab and the connector of skeleton that is contained in wherein, simultaneously can also be bonding with concrete outer plate.Because the existence of cage of reinforcement and the use of pouring type, integrality of wall is compared the raising that the formula body of wall of building by laying bricks or stones has internal.The sound insulation property of body of wall: the concrete wall panel can play the sound insulation effect, and there is cavity in light weight concrete construction inside, can effectively improve the sound absorbing capabilities of body of wall.Functional performance: can add fiber in the concrete that precast concrete plank uses; Inside can be provided with steel wire or fleece; Be used to improve the bending resistance and the toughness of plate, not only can improve the anti-fight of metope and hold the nail ability, also can play reinforcement effect positioning wire.
