Abstract
The invention discloses a steel plate precast concrete double-plate shear wall which comprises steel plates, anti-sliding keys, profile steels, precast concrete wall pieces, cavities and truss steel bars, wherein the steel plates are arranged at the central positions between the two precast concrete wall pieces, four sides of the steel plates are respectively welded with end column internal profile steels and beam internal steel plates or the profile steels, the anti-sliding keys are arranged on the steel plates, the precast concrete wall pieces and the steel plates are connected into a whole through the truss steel bars and the anti-sliding keys, and concrete is poured in the cavities and the profile steels in the shear wall. The shear wall disclosed by the invention is simple in structure, not only solves the problem of insufficient connection of the upper and lower layers of wall bodies, but also enhances the overall performance of the superposed part of the wall bodies.
Description
Technical field
The invention belongs to building structure field, relate to the two plate shear walls of a kind of steel plate precast concrete.
Background technology
Along with China's industrialization of construction industry process is constantly pushed ahead, country advocates assembled architecture energetically.The two plate shear walls of precast concrete are new structure of introducing from Germany, in Germany, have applied nearly 20 years, have reached the requirement of standardized designs, suitability for industrialized production and prefabricated construction.Germany is that a few earthquake is national, and this structure is not considered shockproof requirements.And China's earthquake takes place frequently, and must improve and could extensively promote at home this structure.
Mainly there are following problems in the two plate shear walls of precast concrete when application: 1. after rigging out, while building the cavity concrete, while especially selecting self-compacting concrete, the both sides prefabricated panel produces crack, even off normal owing to connecting not enough meeting; 2. lack enough connections between the levels body of wall, larger lateral displacement easily occurs; 3. the overall performance of two plate shear wall superposed surfaces weakens to some extent than full-situ shear wall; 4. the edge member construction is complicated, has extended the duration.
, due to the existence of above-mentioned problems, the two plate shear wall structure propagation and employments at home of this precast concrete have been hindered.
Summary of the invention
The present invention proposes the two plate shear walls of a kind of steel plate precast concrete, can strengthen the overall performance between superposed surfaces, alleviate the difficulty of construction of edge member, can also strengthen levels and connect, make stressed more reasonable, structure is more reliable.
The technical solution used in the present invention is: the two plate shear walls of a kind of steel plate precast concrete, comprise that steel plate, antiskid move key, shaped steel, pre-cast concrete walling sheet, cavity and truss bars, described steel plate is placed in two centers between the pre-cast concrete walling sheet, steel plate four limits respectively with newel post in steel plate or shaped steel welding in shaped steel and beam, be provided with antiskid on steel plate and move key, move key by truss bars and antiskid between described pre-cast concrete walling sheet and steel plate and connect into integral body, concreting in the cavity in described shear wall and shaped steel.
In order to make the rigidity of structure more reasonable and reduce steel using amount, can punch in the steel plate optional position, can also strengthen steel plate and concrete bonding, globality is better.Still need strengthen if the both walls sheet connects, can place at the place of punching truss bars.
, as preferably, can weld stud, reinforcing bar, channel-section steel or steel loop move key as antiskid on steel plate.Can arrange more be arranged symmetrically with the welding antiskid move key, also can adopt unsymmetric form.Antiskid moves key and guarantee enough anchorings in the precast concrete panel of both sides, and takes into account the pre-erection concrete cover.
As preferably, steel plate thickness is between 6～20mm.Described concrete is self-compacting concrete or ordinary concrete.
As preferably, in sleeper, shaped steel adopts closed cross-section, selects round steel pipe, square steel pipe or rectangular steel pipe.The round steel pipe diameter is between 50～158mm, and square steel pipe or the rectangular steel pipe length of side are between 50～160mm.
Why the present invention chooses closed cross-section shaped steel, is due to after steel plate and shaped steel welding, is subject to the restriction of steel plate position, can't add stirrup in sleeper.Closed cross-section is to the effect of concrete Constrained, thereby guaranteed the performance of structure.
Beneficial effect of the present invention:
1, truss bars and the welding antiskid steel plate that moves key can guarantee the overall performance of the two plate shear wall superposed surfaces of precast concrete, improves its collaborative work ability;
2. steel plate or shaped steel welding in steel plate and upper underbeam, can strengthen the connection between levels, prevents slippage, guarantees the overall performance of building.
3. in steel plate and sleeper, shaped steel welds, and can simplify the difficulty of construction of edge member, guarantees the anti-seismic performance of structure.
Description of drawings
Fig. 1 is the horizontal sectional view of shear wall of the present invention.
Fig. 2 is the schematic diagram that punches of invention light plate.
The specific embodiment
The present invention will be further described below in conjunction with the drawings and specific embodiments.
As illustrated in fig. 1 and 2, by truss bars 4 and the anti-shearing key 3 that is welded on steel plate 1, both sides pre-cast concrete walling sheet 5 and steel plate 1 are connected to become integral body.The size of steel plate 1, greater than pre-cast concrete walling sheet 5, is all stretched out pre-cast concrete walling sheet 5, welding during convenient lifting.The surperficial opening holes 7 of steel plate 1, can strengthen steel plate and concrete bonding, reduces simultaneously rolled steel dosage.Shaped steel 2 is completed with substructure at the scene simultaneously, and the edge member of body of wall at the scene formwork and cavity 6 cast-in-place.After body of wall is in place, with steel plate or shaped steel, 2 welding of edge member shaped steel in steel plate 1 and beam.Next at edge member place formwork, then concreting, and preferentially select self-compacting concrete.
Should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.In the present embodiment not clear and definite each ingredient all available prior art realized.
