Abstract

The utility model discloses a dual plate shear wall with a steel plate and prefabricated concrete. The dual plate shear wall comprises a steel plate, anti-slip buttons, section steel, prefabricated concrete wall sheets, a cavity and truss steel bars. The steel plate is placed at the center position between two prefabricated concrete wall sheets, the four edges of the steel plate are connected with terminal column inner section steel and beam inner steel plate or section steel by welding; the steel plate is provided with the anti-slip buttons; the prefabricated concrete wall sheets are integrated with the steel plate through the truss steel bars and the anti-slip buttons; and concrete is casted in the cavity in the shear wall and the section steel. According to the shear wall, the construction is simple, insufficient connection of upper and lower layer walls is prevented, and the integrity of the superposition of the wall is reinforced.

Description

The two plate shear walls of steel plate precast concrete
Technical field
The utility model belongs to building structure field, relates 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, must this structure be improved and could extensively be promoted at home.
Some problems below the two plate shear walls of precast concrete mainly exist when application: 1. after rigging out, while building cavity concrete, while especially selecting self-compacting concrete, both sides prefabricated panel produces crack, even off normal owing to connecting not enough meeting; 2. between levels body of wall, lack enough connections, easily occur larger lateral displacement; 3. the overall performance of pair plate shear wall superposed surfaces weakens to some extent compared with full-situ shear wall; 4. edge member construction is complicated, has extended the duration.
Due to the existence of above-mentioned problems, hindered the two plate shear wall structures of this precast concrete propagation and employment at home.
Utility model content
The utility model 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 rationally, structure is more reliable.
The technical solution adopted in the utility model 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 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, on steel plate, be provided with antiskid and move key, between described pre-cast concrete walling sheet and steel plate, by truss bars and antiskid, move key 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 rationally and to reduce steel using amount, can punch in steel plate optional position, can also strengthen steel plate and concrete bonding, globality is better.If both walls sheet connects, still need to strengthen, can place at the place of punching truss bars.
As preferably, can on steel plate, weld stud, reinforcing bar, channel-section steel or steel loop move key as antiskid.Can arrange more be arranged symmetrically with welding antiskid move key, also can adopt unsymmetric form.Antiskid moves key and in the precast concrete panel of both sides, guarantees enough anchorings, 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 utility model 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, cannot in sleeper, add stirrup.Closed cross-section is to the effect of concrete Constrained, thereby guaranteed the performance of structure.
The beneficial effects of the utility model:
1, the steel plate that truss bars and welding antiskid move 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.
Accompanying drawing explanation
Fig. 1 is the horizontal sectional view of the utility model shear wall.
Fig. 2 is the schematic diagram that punches of utility model light plate.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As illustrated in fig. 1 and 2, by truss bars 4 and be welded on anti-shearing key 3 on steel plate 1 both sides pre-cast concrete walling sheet 5 and steel plate 1 are connected to become to integral body.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, reduces 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, by 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.
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.
