Abstract
The utility model discloses a splicing structure of an overlapped floor slab. The splicing structure comprises a prefabricated concrete slab, a lower layer steel bar net, truss steel bars, additional steel bars, an upper layer steel bar net and cast-in-place concrete; the truss steel bars are bound on the lower layer steel bar net poured in the prefabricated concrete slab; an upper layer steel bar frame is erected on the top surfaces of the truss steel bars. The additional steel bars are additionally arranged at the lower layers of splicing seams of the overlapped floor slab, and the overlapped floor slab is the whole cast-in-place concrete. The splicing structure of the overlapped floor slab ensures the rationalization in slab splitting and the reliability of the splicing structure, ensures the integral property of the structure and avoids the occurrence of cracks at the splicing parts.
Description
Technical field
The utility model relates to a kind of dividing method and splicing structure of laminated floor slab, belongs to prefabrication and assembly construction laminated floor slab technical field of structures in construction work.
Background technology
Along with the continuous propelling of China's industrialization of construction industry process, the be faced with new challenges builing industry integral body of ，Er China of building trade still belongs to extensive development mode, is difficult to meet the energy-saving and emission-reduction requirement that " 12 " propose.18 large after, building energy saving industry obtains more development opportunity, " industrialization of construction industry, housing industrialization " is Building Trade in China the only way which must be passed of transition.
Other member splicing node processing difficulties of full prefabricated slab and building structure, globality weakens to some extent.Laminated floor slab belongs to prefabricated assembly structural system, is a kind of partial precast part site concrete, combines the advantage that prefabricated assembled industrialization degree is high and full cast-in-place integral is good, can meet the requirement of standardized designs, batch production production and prefabricated construction.
When floor area compare great Shi， factory mould can not meet the production requirement of once-forming, have to large plate to be cut apart, after plant produced completes, to scene, carry out respectively assembled.Yet irrational dividing method and splicing structure will cause the change of plate stress performance, and in stitching portion, easily there is crack.
Utility model content
The rationalization that the utility model is cut apart in order to ensure plate and the reliability of splicing structure, the overall performance of assurance structure, avoids the appearance of stitching portion crackle, and a kind of splicing structure of laminated floor slab is provided.
The technical solution adopted in the utility model is: a kind of splicing structure of laminated floor slab, comprise precast concrete plank, lower floor's steel mesh reinforcement, truss bars, additional bar, top mat and cast-in-situ concrete, described truss bars colligation is on lower floor's steel mesh reinforcement, lower floor's steel mesh reinforcement is cast in precast concrete plank, described top reinforcement frame stands on truss bars end face, the splicing seams place lower floor of this laminated floor slab adds additional bar, and described laminated floor slab is integral cast-in-situ concrete.
As preferably, in the situation that engineering production capacity allows, described laminated floor slab splicing seams as far as possible near or be arranged on plate across negative moment area.In the time of should choosing all plates of vertical direction of cutting apart direction step into row live load least favorable and arrange when calculating hogging moment, resulting hogging moment position is for reference to carrying out partition seam setting.
As preferably, splicing seams is passed through in the steel mesh reinforcement bending of described lower floor, between described bending place and splicing seams, leaves protective layer thickness,
As preferably, described laminated floor slab splicing seams place precast concrete plate thickness can suitably reduce, and length should meet can place additional bar.
As preferably, the bending that also can not make progress of splicing seams place lower floor reinforcing bar, and block in precast floor slab, edge joint position adds additional bar.
As preferably, described laminated floor slab splicing seams place can add upper strata additional bar.
As preferably, the splicing seams in described same straddle can be one or more, and integral prefabricated concrete slab can divide two or polylith to splice.
As preferably, described additional bar can be two-way setting, also the additional bar perpendicular to splicing seams direction can be only set.
As preferably, described lower floor steel mesh reinforcement bends at splicing seams place and the length of extending is between 200～1500mm.
The beneficial effects of the utility model:
1. prefabricated superimposed sheet is that structure is also the template of structure, has saved an on-the-spot die process, and energy-conserving and environment-protective, reduce cost at the reduction of erection time.
2. the utility model is first reasonably determined piece split position on the basis of reliable piece structure, guarantees structure tension performance.
3. additional bar and lower floor's reinforcing bar bend and cross piece and can guarantee structural integrity, avoid crack to occur.
Accompanying drawing explanation
Fig. 1 is the pre-erection schematic diagram in the utility model laminated floor slab;
Fig. 2 is laminated floor slab embodiment 1 sectional drawing in utility model;
Fig. 3 is laminated floor slab embodiment 2 sectional drawings in utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
In the situation that engineering production capacity allows by laminated floor slab partition seam as far as possible near or be arranged on plate across negative moment area.Fig. 1 is the pre-erection schematic diagram in laminated floor slab, and described structure is that pre-erection is spliced.
Embodiment 1: as shown in Figure 2, laminated floor slab comprises precast concrete plank 1, lower floor's steel mesh reinforcement 2, truss bars 3, additional bar 6, top mat 5 and cast-in-situ concrete 4.Truss bars 3 colligations are in lower floor's steel mesh reinforcement 2 and be cast in precast concrete plank 1.Splicing Shi seam crossing lower floor adds 6, two precast concrete planks 1 of additional bar thickness in the scope of edge joint position additional bar 6 and reduces, and lower floor's reinforcing bar of close piece can bend and cross seam in the place of leaving enough protective layer thickness.5 of top mats stand on truss bars 3 end faces, and edge joint position can add upper strata additional bar 6, last concreting.It should be noted that precast concrete plank 1 inner side should plucking processes to increase and cast-in-situ concrete 4 bondings.
Embodiment 2: as shown in Figure 3, two precast concrete planks 1 do not change precast concrete plank 1 thickness at edge joint position, not by 2 bendings of lower floor's steel mesh reinforcement, and block in precast concrete plank 1 yet, edge joint position adds additional bar 6, and all the other ways are identical with embodiment 1.
It should be pointed out that for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.In the present embodiment not clear and definite each ingredient all available prior art realized.
