Description
Technical Field
The invention relates to the technical field of building structure engineering, in particular to a partially prestressed assembled shear wall structure.
Background
Prefabricated building was first started in western europe and later home industrialization was started to expand to countries such as the united states, canada, japan, etc.
The areas in the United states are large, diversified development is carried out, and the prestress prefabricated part is widely applied. The standardization, specialization and socialization degree of the residential components are very high and almost reach 100 percent; the German fabricated house mainly adopts a superimposed sheet, concrete and shear wall structure system, adopts a component fabricated and concrete structure, and has good durability; the concept of fabricated houses was proposed in 1968 in japan, and the quality of precast concrete structures was ensured by legislation, and the powerful support of governments solved the contradiction between standardization, mass production and house diversification.
The assembled building in China is newly rising in recent years, and people and technology are very deficient. At present, multi-story high-rise residential buildings in China still adopt cast-in-place concrete shear wall structures, and the structure system has the defects of low industrialized production degree, complex site construction conditions and the like, so the assembled shear wall system becomes a research and development focus of integrated enterprises integrating real estate, engineering design, prefabricated member production and construction in recent years.
The evaluation grades of the assembled building in China are classified into A grade, AA grade and AAA grade. When the assembly rate is 60% -75%, the building is evaluated as a class A assembly building; when the assembly rate is 76% -90%, the AA-level assembly type building is evaluated; when the assembly rate was 91% or more, the AAA-level assembly type building was evaluated. The higher the assembly rate is, the higher the grade is, the more energy-saving and environment-friendly is realized, and the more time and labor are saved. In an assembled shear wall system, the connection design is very important because the bending moment at the storey is the largest and is the most proper position for horizontal splicing of the upper shear wall and the lower shear wall. If the fully assembled cast-in-place concrete-free operation is to be realized, a prestress structure is adopted, and the prestress assembled shear wall structure can effectively solve the problem of crack common problems of prefabricated and cast-in-place concrete interfaces commonly existing in an assembled building.
The vertical connection of the assembled shear wall mainly comprises two modes of steel sleeve grouting connection and slurry anchor lap joint connection. The steel sleeve is connected in a grouting way, so that the cost is high and the quality inspection is difficult. The lap joint length of the reinforcing steel bars connected by the slurry anchors is longer, and the installation and the operation are not easy. Therefore, there is an urgent need to propose a splicing method of a partially prestressed assembled shear wall with quick construction and reliable quality.
Disclosure of Invention
The invention aims to solve the problem that the continuity of a part of prestress assembled shear wall is difficult to guarantee after lap joint, and provides a part of prestress assembled shear wall structure. The double-row continuous cable distribution structure ensures the continuity and the integrity of the assembled shear wall between layers and between walls, and strengthens weak links of structural connection. The exposed steel stranded wires of the first layer of shear wallboard extend into the anchorage device of the foundation for fixation, and the exposed steel stranded wires are tensioned and fixed in the anchorage device at the upper end of the anchorage continuous length device of the shear wallboard; the exposed steel strands of the second layer of shear wall plates are fixed in the anchor at the lower end of the anchor extender of the first layer of shear wall plates, the exposed steel strands are tensioned and fixed in the anchor at the upper end of the anchor extender of the anchor layer of the shear wall plates, and the rest layers of shear wall plates are similar. The invention ensures the continuity and the integrity of the assembled shear wall between layers and among walls, can meet the requirement of rapid industrialization, and creates a new way for popularizing and applying partial prestress assembled shear wall structures.
The technical scheme adopted by the invention is as follows: a partially prestressed assembled shear wall structure comprises a partially prestressed shear wall, an auxiliary tool clamping piece flat pusher and a prefabricated floor plate;
the part of the prestress shear wall comprises non-prestress ribs, pre-embedded steel pipes, prestress ribs, an anchoring length-continuing device and anchor ribs; the non-prestressed tendons are embedded in steel joints at the positions of the upper and lower shear wall joints and are connected through welded steel joints; the prestress rib is arranged in the pre-buried steel pipe, is a bonded prestress steel strand, and adopts double-row continuous and straight curve mixed ropes;
the anchoring length-increasing device is arranged in the shear wall plate and is close to the joint of the adjacent shear wall plate, and the prestressed tendons in the upper layer of shear wall plate and the lower layer of shear wall plate are connected to achieve the effect of anchoring layer by layer and plate by plate; the anchoring length-continuing device comprises a transverse stress plate, a vertical stress plate, a blocking piece, a groove-shaped bottom baffle and an anchor; the anchors are welded on two parallel transverse stress plates of the anchor length continuing device respectively, the anchors for anchoring the prestressed tendons of the lower shear wall are upper end anchors, and the upper end anchors are arranged on the upper stress plates of the transverse stress plates; the anchor used for anchoring the prestressed tendons of the upper shear wall is a lower anchor, the lower anchor is arranged on a lower stress plate of the transverse stress plate, and a vertical stress plate is connected between the two parallel transverse stress plates; the blocking sheets are vertically welded on the thin steel plates at two sides of the anchoring length-increasing device, and holes are formed in the wall surface and used for field installation operation (the blocking sheets are not needed on the surface close to the outer side of the outer wall, so that leakage of the holes is prevented); the anchor bars are welded on the outer side of the anchor length-extending device;
the prefabricated floor plate is placed on the protruding part of the inner side of the partial prestress shear wall, is connected with the partial prestress shear wall through welding and bolts, and is filled with structural adhesive in a connecting gap in a pressing mode; the clamping piece flat pusher clamping piece is arranged below the anchorage device of the anchorage continuous device and is used for adjusting the height difference between the clamping pieces in the anchorage device, particularly the clamping pieces of the anchorage device at the lower end in the anchorage continuous device, the space is smaller, and enough working surface can not be provided when the height between the clamping pieces is adjusted, so that the construction requirement can not be met.
Preferably, each layer of the fixed continuous length device is formed by welding steel plates, and the transverse stress plate is thicker than the groove-shaped bottom baffle plate.
Preferably, the prestress rib adopts a single prestress steel strand, so that the prestress rib is convenient to put through in a steel pipe.
Preferably, the barrier sheet is a 0.3mm steel sheet
The beneficial effects are that: the prestress steel strands are adopted in the partial prestress assembled shear wall, and the prestress steel strands are arranged in double rows continuously, so that the continuity and the integrity of the assembled shear wall between layers are ensured, and the weak links of structural connection are reinforced. The prestressed steel strand is flexible in cable arrangement, and the vertical steel strand is mixed with the cable arrangement by a straight curve. Because the cross section area of the wall between the windows is suddenly reduced, the wall body is likely to be in a shearing stress state after being subjected to earthquake action, cross cracks are easy to occur, and the prestress rib adopts a curve cross cable arrangement mode to make up for the defect of the shearing resistance of steel. And embedding an anchoring continuous length device in a part of the prestress assembly type shear wall, and effectively connecting the steel strands in the adjacent shear wall when the anchoring continuous length device stretches and fixes the prestress steel strands. The exposed steel strands of the first layer shear wall are stretched and fixed in an anchorage device at the upper end of the wallboard anchoring continuous extender and protected by a groove-shaped bottom baffle; the exposed steel strands of the second layer shear wall extend into the anchor at the lower end of the anchor extender of the first layer shear wall plate to be fixed, and are protected by the groove-shaped bottom baffle plate. After the steel strand is stretched and fixed in the anchoring continuous device, the steel strand is matched with the filling of high-strength grouting material, so that the strength and the effect of connection can be fully ensured. The invention can effectively solve the common problem of cracks of prefabricated and cast-in-place concrete interfaces commonly existing in the assembled building.
