Abstract
The invention relates to an exposed aggregate connecting method of a prefabricated half shear wall and a beam. The method comprises pouring the shear wall in two steps, pouring concrete only to the bottom of the beam during shear wall fabrication, aggregate-exposing the cross section of the shear wall, mounting the prefabricated beam with reserved anchoring bars after binding steel bars on the upper portion of the shear wall, extending the anchoring bars on the beam into the shear wall and lastly pouring concrete for the upper portion of the shear wall, accordingly the shear wall and the beam are reliably connected to form a whole. The cross section of the connection of the prefabricated portion and the upper pour-in-site portion of the shear wall is aggregate-exposed to well combine new concrete and oil concrete and further achieve more reliable connection. The exposed aggregate connecting method for the prefabricated shear wall and the beam achieves the object of being provided with bearing capacity and reliability which are equal to or even higher than those of the connection of a pour-in-site shear wall and a pour-in-site beam by connecting the prefabricated shear wall and the beam in a prefabricated-frame-corewall structure on a flat surface, provides technical support for application of an assembly-type concrete frame-corewall structure, achieves industrialized prefabricated component production, effectively improves the engineering quality and the production efficiency, reduces building pollution, advocates green and environmental construction and advances the development of modern architectural industrialization. The tooth-form connecting method for the prefabricated half shear wall and the beam can be applied to a prefabricated frame and shear wall structure.
Description
Technical field
The present invention relates to the link technique in shear wall and Liangping face in precast frame-core wall structure.Provide a kind of prefabricated half sheet shear wall and beam undisguisedly to expect method of attachment.
Background technology
Since nineteen sixty-eight, Japan proposed this concept of housing industrialization, precast concrete assembled-type house has experienced different developing stage, up to the present, external and China's Hongkong assembled-type house system construction technology comparative maturity, China mainland is still slower in research and experimental stage development, though have successful story, and quantity seldom.Prefabricated dwelling house is the effective way that realizes housing industrialization, and it is one of the key link that prefabricated units are connected in this approach; Prefabricated units are produced in batch production, can effectively improve workmanship and production efficiency, reduce pollution form construction, advocate environmental protection construction.Along with prefabricated costruction development, prefabricated assembled shear wall structure becomes the primary structure form of current China house.
Prefabricated building are houses that the members such as a kind of lightweight heat-insulating composite wallboard by batch production Prefabrication, floor, roof panel and pillar of genus building trade are assembled.Precast frame-core wall structure system also will become a main trend of building trade development in the future, and one end that its beam is connected with Core Walls Structure usually there will be beam and situation about being connected in wall plane.For beam, at home and abroad study seldom with the technology and the method that are connected in shear wall plane.
Summary of the invention
In order to advance the development of modern architecture industrialization, the invention provides the connected mode of a kind of precast shear wall and beam, present technique is by building shear wall at twice, realizes being connected of precast shear wall and beam, finally makes the two become the integral body with reliable connection.
The technical scheme that technical solution problem of the present invention adopts is: during precast shear wall, concrete only accomplishes that beam bottom and its cross section should do undisguised material and process, tie up after the reinforcing bar of shear wall the first half the precast beam install with reserved anchor bar to corresponding position (it is interior that the anchor bar on beam stretches into shear wall), be finally shear wall the first half concreting, the vertical muscle of its central sill should be determined according to actual conditions in anchorage length within the walls.
The invention has the beneficial effects as follows: by prefabricated half sheet shear wall and beam, undisguisedly expect that link technique makes the two firm and reliable connection that becomes one, realize the reliable connection planar of precast shear wall and precast beam.Reach to be connected with beam with cast-in-place shear wall and compare the object with identical even higher supporting capacity and reliability, for the application of assembly concrete framework core wall structure provides technical support, realize batch production and produce prefabricated units, can effectively improve workmanship and production efficiency, reduce pollution form construction, advocate environmental protection construction, advance the development of modern architecture industrialization.
Accompanying drawing explanation
Accompanying drawing is that prefabricated half sheet shear wall and beam are undisguisedly expected connection procedure figure, the first step: precast shear wall and beam; Second step: beam is installed to relevant position; The 3rd step: build shear wall the first half concrete.
The specific embodiment
1. by reinforcing bar the formwork supporting plate of designing requirement colligation shear wall the latter half;
2. by reinforcing bar the formwork supporting plate of designing requirement colligation beam, during assembling reinforcement, beam-ends should reserve one section, the anchorage length that this segment length should meet design requirement;
3. concreting maintenance, and process doing undisguised material with the cross section of shear wall the first half junction;
4. the reinforcing bar on colligation shear wall top formwork supporting plate;
5. beam is installed to relevant position and the reserved anchor bar of beam-ends is inserted in shear wall fixing;
6. build shear wall the first half concrete maintenance.
Claims (2)
1. prefabricated half sheet shear wall and beam are undisguisedly expected method of attachment, it is characterized in that: by shear wall is built at twice, during precast shear wall, concrete only accomplishes that beam bottom and its cross section should do undisguised material and process, tie up after the reinforcing bar of shear wall the first half the precast beam install with reserved anchor bar to corresponding position, anchor bar on beam stretches in shear wall, be finally shear wall the first half concreting, finally make the two become the integral body with reliable connection.
2. prefabricated half sheet shear wall according to claim 1 and beam are undisguisedly expected method of attachment, it is characterized in that: the cross section that the pre-erection of shear wall is connected with the cast-in-place part of the first half should be done undisguised material and be processed, make the better combination of new-old concrete, connect more reliable.
