Abstract

The invention discloses the two plate shear wall of a kind of steel plate precast concrete, comprise steel plate, resistant slide key, shaped steel, pre-cast concrete walling sheet, cavity and truss bars, described steel plate is placed in the center between two panels pre-cast concrete walling sheet, steel plate four limit is welded with steel plate in shaped steel in newel post and beam or shaped steel respectively, steel plate is provided with resistant slide key, entirety is connected into by truss bars and resistant slide key, concreting in the cavity in described shear wall and shaped steel between described pre-cast concrete walling sheet and steel plate.Shear wall simple structure of the present invention, not only solves the not enough problem of levels wall connecting, and strengthens the overall performance at the superimposed place of body of wall.

Description

The two plate shear wall of steel plate precast concrete
Technical field
The invention belongs to building structure field, relate to the two plate shear wall 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 wall of precast concrete is the new structure introduced from Germany, has applied nearly 20 years, reach the requirement of standardized designs, suitability for industrialized production and prefabricated construction in Germany.Germany is a few earthquake country, and this structure does not consider shockproof requirements.And China's earthquake takes place frequently, must carry out improvement to this structure could extensively promote at home.
Mainly there are following problems when applying in the two plate shear wall of precast concrete: 1., after rigging out, when building cavity concrete, when especially selecting self-compacting concrete, both sides prefabricated panel can produce crack, even off normal owing to connecting deficiency; 2. lack enough connections between levels body of wall, easily occur larger lateral displacement; 3. the overall performance of pair plate shear wall superposed surfaces comparatively full-situ shear wall weaken to some extent; 4. edge member construction is complicated, extends the duration.
Due to the existence of above-mentioned problems, hinder the two plate shear wall structure propagation and employment at home of this precast concrete.
Summary of the invention
The present invention proposes the two plate shear wall of a kind of steel plate precast concrete, the overall performance between superposed surfaces can be strengthened, alleviate the difficulty of construction of edge member, levels can also be strengthened and connect, make stressed more rationally, structure is more reliable.
The technical solution used in the present invention is: the two plate shear wall of a kind of steel plate precast concrete, comprise steel plate, resistant slide key, shaped steel, pre-cast concrete walling sheet, cavity and truss bars, described steel plate is placed in the center between two panels pre-cast concrete walling sheet, steel plate four limit is welded with steel plate in shaped steel in newel post and beam or shaped steel respectively, steel plate is provided with resistant slide key, entirety is connected into by truss bars and resistant slide key, concreting in the cavity in described shear wall and shaped steel between described pre-cast concrete walling sheet and steel plate.
In order to make the rigidity of structure more rationally and reduce steel using amount, can punch in steel plate optional position, can also strengthen steel plate and concrete bonding, globality is better.Still need to strengthen if both walls sheet connects, truss bars can be placed at the place of punching.
As preferably, can on steel plate weld stud, reinforcing bar, channel-section steel or steel loop as resistant slide key.Can arrange more and be arranged symmetrically with welding resistant slide key, also can adopt unsymmetric form.Resistant slide key ensures enough anchorings in the precast concrete panel of both sides, and takes into account 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.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 welds with shaped steel, is subject to the restriction of steel plate position, cannot adds stirrup in sleeper.Closed cross-section to the effect of concrete Constrained, thus ensure that the performance of structure.
Beneficial effect of the present invention:
1, the steel plate of truss bars and welding resistant slide key can ensure the overall performance of the two plate shear wall superposed surfaces of precast concrete, improves its collaborative work ability;
2. steel plate welds with steel plate in upper underbeam or shaped steel, can strengthen the connection between levels, prevent slippage, ensures the overall performance of building.
3. steel plate welds with shaped steel in sleeper, can simplify the difficulty of construction of edge member, ensures the anti-seismic performance of structure.
Accompanying drawing explanation
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.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
As illustrated in fig. 1 and 2, by truss bars 4 and the anti-shearing key 3 be welded on steel plate 1, both sides pre-cast concrete walling sheet 5 and steel plate 1 are connected to become entirety.The size of steel plate 1 is greater than pre-cast concrete walling sheet 5, all stretches 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, reduce rolled steel dosage simultaneously.Shaped steel 2 completes 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, steel plate 1 and steel plate in beam or shaped steel, edge member shaped steel 2 are welded.Next at edge member place formwork, then concreting, and preferentially select self-compacting concrete.
It 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.The all available prior art of each ingredient not clear and definite in the present embodiment is realized.
