Abstract
The present invention provides a technical scheme of concrete laminated member box. Said laminated member box is a hollow closed concrete box body, said box body includes bottom plate, top plate and side walls. Said invention also provides the concrete structure of the bottom plate, top plate and side walls, said whole box body and after-poured ribbed beam can be laminated into one body, the bottom plate and top plate of said box body are respectively formed into upper and lower flanges of after-poured ribbed beam, the side walls of said box body are formed into one portion of the after-poured ribbed beam, so that the laminated member box and after-poured concrete ribbed beam can be formed into large hollow cavity concrete floor.
Description
Affiliated technical field:
What the present invention relates to is concrete prefabricated superposed member, template form and concrete floor system structural system in the building trade.
Background technology:
In existing processing cast-in-situ hollow building roof, cavity building roof, close rib building roof, arch without beam technology, various forms of templates such as used " box ", " shell " of pore-forming, " pipe " all are not primary structure members, and the overall structure that all can not participate in superstructure is stressed.Water the edge of a wing of girt strip after the top board of " box ", " shell " and base plate can not form, its sidewall also can't with after water that girt strip is superimposed to become integral body and stressed jointly.In existing superposed member, have only the component form of superimposed sheet, superposed beam, there is not the superposed member of casing form, especially there is not the casing form of integrally closed.And do not adopt this invention superposed member case to process big cavity cast-in-situ floor is very difficult.The problem that prior art that Here it is exists.
Summary of the invention
The invention provides a kind of technical scheme of concrete laminated member box, solved the deficiencies in the prior art.This programme adopts the concrete laminated member case as superposed member, with after water girt strip and be combined into whole big cavity building roof.Superimposed case plays template action simultaneously, no longer removes.The superposed member case of this programme is the casing of a precast concrete hollow sealing, and it forms with the effect of each several part as follows:
1. the top board of casing and base plate: the stressed connecting lacing wire that stretches out perforation in the slave plate with after water girt strip and be anchored at, make top board, base plate and back pouring concrete girt strip connect into integral body, become the last bottom flange of girt strip.Its thickness determines that by the whole Force Calculation of superstructure minimum thickness is not less than 40mm.
2. the sidewall of casing: sidewall with after water girt strip and connect into integral body, become the part of I-shaped girt strip web.Be equivalent to widen the girt strip web.
3. at the periphery of roof box and the periphery of base plate embedded slot is arranged, the effect of embedded slot is the contact surface that strengthens back pouring concrete and casing, and makes the top board of casing and base plate and back pouring concrete that the build-in interlocking be arranged.
4. there is the protruding key of power transmission junction inboard at last embedded slot and the top board downside.In following embedded slot junction inboard and the base plate upside the protruding key of power transmission is arranged also.The effect of the protruding key of power transmission be allow top board, base plate and after the internal force that waters between the girt strip obtain more reliable transmission.
5. recessed occlusal crib is arranged on the sidewall of casing.The effect of occlusal crib is the interconnect function of reinforced sidewall and back pouring concrete girt strip.
6. from wall box the attaching means that stretches out is arranged, its effect is: when adjacent attaching means welded together, the horizontal distortion trend of wall box suffered restraints, make sidewall can with the girt strip compatible deformation, increase the friction and the adhesion stress of sidewall and girt strip.Another effect of attaching means is its horizontal support as wall box, effectively improves the ability of sidewall opposing back pouring concrete lateral pressure.

Fig. 1 is the schematic diagram of superposed member case of the present invention
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1
Fig. 3 is an embodiment of the present invention, with the member case with after water the floor construction schematic diagram that girt strip is formed.
Fig. 4 is a superstructure floor map after the invention process.
Among the figure, 1 is the superposed member box body, and 2 are the protruding key of power transmission, and 3 is occlusal crib, and 4 is embedded slot, and 5 is the connecting lacing wire of top board and base plate, and 6 is the sidewall attaching means, and 7 is back pouring concrete girt strip, and 8 is the girt strip longitudinal reinforcement.
The specific embodiment:
In order to be illustrated more clearly in this programme technical characterstic, below the present invention is described further.
One. can find out that from accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 the present invention is the concrete casing of a hollow sealing.Whole box body is a prefabricated superposed member, its base plate, top board and sidewall all with after water the girt strip concrete and link into an integrated entity, constituted the Cast-in-place Concrete Building Floor overall structure.The base plate of casing and top plate thickness determine that by the whole Force Calculation of superstructure minimum thickness is 40mm.Firm in order to guarantee that superimposed case is connected with the back pouring concrete, leave embedded slot (4) all around respectively at the top board of casing and base plate, this groove increased top board and base plate and after water the concrete contact surface of girt strip, also making has had the effect of mechanical snap on the contact surface.In the inboard junction of embedded slot up and down the protruding key of power transmission (2) is arranged with the top board base plate.Protruding key of power transmission and embedded slot acting in conjunction are passed to the internal force of girt strip (7) on the top board and base plate of superimposed case more reliably.Recessed occlusal crib (3) is arranged on wall box, and the effect of occlusal crib is being connected of reinforcement case sidewall and back pouring concrete girt strip (7).Stretch out attaching means from wall box, its effect is when adjacent attaching means links together, and the horizontal distortion trend of wall box suffers restraints, make sidewall can with the girt strip compatible deformation, increase the friction of sidewall and girt strip.Another effect of attaching means is its horizontal support as wall box, can effectively improve the ability of sidewall opposing back pouring concrete side pressure.In top board and base plate the stressed connecting lacing wire (5) that stretches out is arranged, (5) are steel bar stresses, participation structure whole stressed and with vertical muscle (8) grappling iron of girt strip together.
Two. it is as follows to utilize the present invention to process the step of cast-in-place concrete building roof:
On a good superstructure soffit formwork, put the superposed member case, the space between each case just as after water the width of girt strip (7).Colligation girt strip reinforcing steel bar cage in the space between each case.It is firm that the vertical muscle (8) of stressed connecting lacing wire (5) that stretches out from the base plate interior of casing and top board inside and girt strip is connected.Attaching means (6) between two adjacent casings be connected firmly, pour into a mould the girt strip concrete at last, just formed the superposed member case with after water the big cavity building roof that girt strip is formed.
