Description

Technical Field

[0001] The utility model relates to the technical field of assembled building structures, in particular to an assembled wall panel and a wall panel system. Background Art

[0002] One of the important measures for the country to promote the development of building industrialization and the transformation and upgrading of the construction industry is to promote the research and application of key technologies in building structure systems, building design, components and accessories. Prefabricated buildings refer to buildings assembled on site using prefabricated components. The advantages of this type of building are fast construction speed, less restrictions on climatic conditions, labor saving and improved building quality.

[0003] At present, when the ends of prefabricated wall panels of prefabricated buildings are connected, horizontal steel bars are extended through the ends of the wall panels, additional lap steel bars are placed on site, and longitudinal bars are inserted in the horizontal lap section. The formwork at the cast-in-place strip is supported, concrete is poured, and the formwork is removed after curing. The overall process is large, the placement of additional lap steel bars and the insertion of longitudinal bars are difficult, and the efficiency is low. In addition, the cast-in-place strip formwork needs to be tied and fixed with pre-embedded nuts on the prefabricated wall panels in advance. The surface quality is different after demoulding, and the outer surface needs secondary treatment such as plastering, which cannot reflect the high quality, high efficiency and low labor characteristics of prefabricated building industrialization. Utility Model Content

[0004] The utility model aims to provide an assembled wall panel and a wall panel system to solve the problems of low construction efficiency and high construction cost in the assembly of existing prefabricated wall panels.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an assembled wall panel, the prefabricated wall includes a concrete layer and an insulation layer located inside the concrete layer, an integrated wire tube is preset in the prefabricated wall, the prefabricated wall is provided with a hand hole groove along its side, the free end of the integrated wire tube passes through the prefabricated wall and is located in the hand hole groove, and the prefabricated wall is provided with a connecting structure for connecting to the assembled wall panel or adjacent components.

[0006] The principles and advantages of this solution are:

[0007] 1. In actual application, in this solution, a connection structure that can be directly installed is set on the prefabricated wall, which eliminates the on-site interlaced binding of steel bars, formwork and concrete pouring processes. After the prefabricated wall panels are hoisted in place, it is only necessary to simply align the connection structures of two adjacent wall panels or wall panels with adjacent strip foundations, beams and other components, and install them. The construction and assembly between the components can be completed quickly, and there is no need to perform demolding and secondary wall plastering as in the background technology. The construction process is simplified, the construction difficulty is greatly reduced, and the high-quality and high-efficiency construction of prefabricated buildings is reflected, while the overall construction cost is also reduced.

[0008] 2. The free end of the integrated wire tube in the utility model is located in the hand hole groove, so that the position between the integrated wire tubes can be adjusted according to the actual construction situation, and the installation flexibility is stronger, which reduces the position accuracy requirements of the integrated wire tube in the prefabricated wall panel, increases the allowable position error range when laying pipes in the production process of the prefabricated wall panel, improves production efficiency, and effectively reduces production costs and later construction costs.

[0009] Furthermore, the connection structure is a shear groove or a shear key provided on the end surface of the prefabricated wall.

[0010] The above-mentioned arrangement enables quick installation and positioning when two adjacent prefabricated wall panels or prefabricated wall panels are assembled with adjacent strip foundations, beams and other components through the cooperation of the shear grooves and shear keys on each other's end faces, saving the time for position adjustment during the lifting process. At the same time, the cooperation between the shear grooves and shear keys eliminates the process of steel plate connection, simplifies the installation process, improves construction efficiency, and shortens the construction period.

[0011] Furthermore, the connection structure is a connection groove arranged on the wall surface of the prefabricated wall.

[0012] During assembly, the connection groove is used to place steel plates and other connecting objects, and the steel plates are fixed by expansion bolts to achieve the connection and fixation between two wall panels or between the wall panels and adjacent strip foundations, beams and other components; after the prefabricated wall panels are hoisted into place, it is only necessary to simply bolt the connecting steel plates, which can quickly complete the installation and fixation, and there is no need for demoulding and secondary wall plastering, which simplifies the construction process and greatly reduces the difficulty of construction, reflecting the high-quality and efficient construction of prefabricated buildings, while also reducing the overall construction cost.

[0013] Furthermore, the hand hole groove has a groove depth of 180-220 mm in the vertical direction, and a groove width along the horizontal width direction of the prefabricated wall is not less than 150 mm.

[0014] In the above setting, the groove width is not less than 150mm to facilitate the arrangement of the free ends of multiple integrated wire tubes in the hand hole groove according to the actual line conditions. The groove depth is 180-220mm to leave assembly margin for the line pipes in the prefabricated floor slabs and adjacent components without affecting the bearing stability of the wall panels, so as to facilitate flexible adjustment of the lines during actual layout, reduce assembly accuracy requirements, and improve construction efficiency.

[0015] Furthermore, a hanging groove is opened on one side of the prefabricated wall, a hanging member is installed in the hanging groove, and the plane where the vertex of the hanging member is located is lower than the side surface of the prefabricated wall.

[0016] The above arrangement makes the plane where the apex of the lifting assembly is lower than the side surface of the prefabricated wall. After transportation and installation, there is no need to cut and repair the protruding part of the lifting component, which reduces the construction workload and improves the construction efficiency.

[0017] Furthermore, the prefabricated wall is provided with a first bolt sleeve embedded in the prefabricated wall for fixing the wall panel diagonal support in the upper and lower sides along the vertical direction; the upper part of the side of the prefabricated wall is provided with a second bolt sleeve embedded in the prefabricated wall for fixing the adjustable support device.

[0018] The above-mentioned pre-embedded first bolt sleeve makes it possible for the wall panel diagonal support to be quickly fixed to the wall panel by the first bolt and the first bolt sleeve during installation of the prefabricated wall panel, and after the installation of the prefabricated wall panel is completed, the wall panel diagonal support can be removed from the first bolt sleeve and reused; the pre-embedded second bolt sleeve makes it possible for the second bolt sleeve to cooperate with the bolt to facilitate the rapid installation of the adjustable horizontal support device independently developed by the applicant on the wall panel during the installation of the floor slab, without the need to set up a scaffolding to support the floor slab, thereby reducing the construction process of scaffolding erection and disassembly, greatly improving the construction efficiency, and after the floor slab construction is completed, the adjustable support device can be removed from the bolt sleeve and reused.

[0019] Furthermore, the prefabricated wall is provided with a connection hole connected to the integrated wire pipe, and the integrated wire pipe radiates around the prefabricated wall with the connection hole as the center to form a plurality of branch pipelines.

[0020] The electrical appliances are installed at the connection holes, and the integrated wire tube radiates around the prefabricated wall with the connection holes as the center, so that multiple line switches can be set along multiple branch pipelines for the electrical appliances, which is convenient for residents to switch the electrical appliances at different locations, effectively improving the convenience of life.

[0021] The utility model also provides another technical solution: an assembled wall panel system, comprising a plurality of assembled wall panels, a connecting steel plate is fixed in the connecting groove of two adjacent assembled wall panels, and a mounting hole is opened on the connecting steel plate.

[0022] Beneficial effects:

[0023] In this solution, the prefabricated wall panels are evenly opened with multiple connection grooves on the wall surface. During assembly, the connecting steel plates are placed in the corresponding connection grooves of the two adjacent prefabricated wall panels, and the connecting steel plates are fixed to the two prefabricated wall panels through the mounting holes using expansion bolts to achieve the connection and fixation of the two. Compared with the steel bar construction and cast-in-place concrete used in the background technology, in this solution, after the prefabricated wall panels are hoisted into place, it is only necessary to simply bolt the connecting steel plates, and there is no need for demoulding and secondary wall plastering, which simplifies the construction process, greatly reduces the construction difficulty, reflects the high-quality and high-efficiency construction of prefabricated buildings, and also reduces the overall construction cost.

[0024] Furthermore, the thickness of the connecting steel plate is smaller than the depth of the connecting groove.

[0025] On the one hand, the above-mentioned arrangement is to ensure that after the prefabricated wall panel and the adjacent components are fixed by the connecting steel plate, the connecting steel plate and the bolt head are completely located within the connecting groove, so as to avoid the connecting steel plate or bolt protruding from the wall surface of the wall panel and requiring secondary grinding by construction workers to ensure the flatness of the wall surface; on the other hand, after the connecting steel plate is installed, the connecting groove is filled with concrete to increase the stability of the connection node. At the same time, the concrete protects the connecting steel plate and bolts to reduce corrosion and extend the service life of the components.

[0026] The utility model also provides another technical solution: an assembled wall panel system, comprising a plurality of assembled wall panels, wherein two adjacent assembled wall panels are connected and fixed by the cooperation of shear keys and shear grooves.

[0027] Beneficial effects:

[0028] In this solution, the prefabricated wall panels are provided with shear grooves or shear keys on their sides. When two adjacent prefabricated wall panels are assembled, they can be quickly positioned through the cooperation of the shear grooves and the shear keys, and there is no need to adjust the installation position too much later. The cooperation between the shear grooves and the shear keys simplifies the steel plate connection process between the two adjacent prefabricated wall panels, greatly improving the construction efficiency. At the same time, the shear grooves and shear key structures enhance the shear strength of the connection between the components. BRIEF DESCRIPTION OF THE DRAWINGS
