Assembled type prefabricated outer wallboard structure and construction method

Abstract

The invention relates to an assembled type prefabricated outer wallboard structure. The assembled type prefabricated outer wallboard structure mainly comprises a local layer outer wallboard, a lower layer outer wallboard, fixing assemblies, separated type angle steel, an L-shaped steel plate and horizontal U-shaped ribs; the lower layer outer wallboard permanent fixing assembly is arranged inside the lower layer outer wallboard and connected with the L-shaped steel plate in an anchoring mode; the outer wallboard top reserved horizontal U-shaped rib in the inner side of the top of the lower layer outer wallboard is connected with the edge beam reserved horizontal U-shaped rib in the end portion of a floor in a welding mode; the local layer outer wallboard and the lower layer outer wallboard are connected vertically through positioning pins; the local layer outer wallboard temporary fixing assembly 1 embedded in the local layer outer wallboard and the separated type angle steel are anchored; and post-filling fine aggregate concrete is poured into a defined space of the lower portion of the separated type angle steel. The assembled type prefabricated outer wallboard structure is high in mounting speed, and upper and lower prefabricated outer wallboards and a beam body are high in connection strength. The invention further provides a construction method of the assembled type prefabricated outer wallboard structure.

Description

technical field [0001] The invention relates to an assembled prefabricated exterior wall panel structure and construction method, which belongs to the technical field of building construction and is suitable for the installation and construction of various types of exterior wall panels in residential and commercial high-rise buildings, especially for installation projects with tight construction schedules. . Background technique [0002] At present, my country's construction industry is progressing very rapidly. Many buildings have adopted the installation and construction technology of prefabricated hanging panels on exterior walls during the construction process. This technology can reflect very good plasticity during the construction process, and can also be very good. It perfectly shows the designer's design intention, and does not require very high expenses during the maintenance process, and the quality of the construction is easy to control, so it is favored by all par...

Problems solved by technology

Among them, when temporarily fixing the outer wall panels of this layer, the temporary fixing components are generally arranged in the keyway (the top of the outer floor slab of the edge beam), so the temporary fixing components here must be removed before the later concrete pouring construction, and the external wall panels of this layer must be removed. The quality of the installation has a certain impact; in addition, the top of the lower exterior wall panels and the side beams are not welded with reserved steel bars in the traditional process, and the connection strength is average; and during the installation of the upper and lower wall panels, the traditional process does not set the vertical Degree adjustment device, it is inconvenient to adjust the operation through measurement

At present, there are many new prefabricated exterior wall panel installation structures on the market, such as the use of spring plate connection (patent number: 201410466822.9). The structure installation process is simple and can greatly improve construction efficiency, but it is only suitable for light prefabricated exterior wall panels. If it is used in the installation of large and heavy prefabricated exterior wall panels, the upper hanging spring plate and the lower hanging spring plate are easily deformed, the installation error is relatively large, and there are certain safety hazards
