Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated buildings, in particular to a precast wall panel component. Background Art

[0002] A prefabricated building refers to a concrete structure building that is prefabricated in a factory and then assembled and connected at the construction site.

[0003] At present, light panels are generally used as materials for non-load-bearing walls in prefabricated buildings, which play a role in enclosing and separating spaces. Light panels are usually standard-width boards (the width generally does not exceed 600 mm), and have advantages such as good sound insulation, strong fire resistance, and low cost.

[0004] However, in the application of existing light panels in non-load-bearing walls, there are disadvantages such as small plate width dimensions requiring multiple assemblies, low wall panel integration, and the need for on-site chiseling, which affect the on-site construction progress and reduce work efficiency. Specifically, due to the small width of existing light panels, on-site construction usually requires assembling multiple light panels, and the levelness and verticality need to be adjusted repeatedly during the assembly process, affecting the on-site construction progress; since light panels are standard-width boards, in order to meet the width dimensions of non-load-bearing walls, when installing the last board, it is usually necessary to cut the light panel, resulting in waste; at the same time, the integration of light panels is relatively low, and on-site chiseling of installation equipment pipelines is required at the construction site, increasing construction procedures, generating construction waste, and it is difficult to control the on-site chiseling quality.

[0005] Building by using precast wall panels for assembly can effectively reduce on-site wet operations, save on-site labor requirements, and at the same time, prefabricating and producing in the factory in advance can shorten the construction period of the building. Therefore, there is an urgent need for a precast wall panel component to solve the problems of low integration of existing light wall panels, multiple on-site assemblies and cuts required for continuous installation of light wall panels, and cumbersome procedures for installing equipment pipelines. Summary of the Utility Model

[0049] For better understanding the above technical solution, the exemplary embodiments of the present utility model will be described in more detail below with reference to the attached drawings. Although the exemplary embodiments of the present utility model are shown in the drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present utility model and to be able to convey the scope of the present utility model completely to those skilled in the art.

[0050] The present utility model provides a precast wall panel member, including a lightweight wall panel, and a concrete frame that surrounds the lightweight wall panel and is connected to the lightweight wall panel by fitting to the edge of the lightweight wall panel. The lightweight wall panel is formed by splicing at least two lightweight strips 3 of the same size in the left - right direction in sequence. The concrete frame and the lightweight strip 3 are integrally manufactured in the factory. A lifting hook 4 for hoisting is provided at the top of the concrete frame. Embedded wire boxes 5 and embedded wire pipes 6 connected to the embedded wire boxes 5 are provided on the lightweight strip 3. Through the wall panel member precast integrally with the lightweight strip 3 and the concrete frame, the wall panel member has good integrity and a relatively large width dimension, and it can realize that only one installation is required for one wall, solving the problems of complex processes and low construction efficiency caused by the relatively small width of the existing lightweight strip 3, multiple assemblies and repeated adjustments during installation.

[0051] The concrete frame includes two construction columns 1 located on the left and right sides of the lightweight wall panel, and two ring beams 2 located on the upper and lower sides of the lightweight wall panel. The lightweight wall panel is connected to the construction column 1 through a first connecting member, and the lightweight wall panel is connected to the ring beam 2 through a second connecting member. The two ring beams 2 are respectively a lower ring beam located below the lightweight wall panel and an upper ring beam located above the lightweight wall panel. A lifting hook 4 for hoisting the precast wall panel member is provided at the top of the upper ring beam.

[0052] The upper and lower sides of the concrete frame are provided with installation grooves 16, and the installation grooves 16 are used to place the connecting members 14 that connect the precast wall panel components to the main building structure, so as to keep the wall surface flat. The connecting member 14 has a bend, and the bend is arranged at a right angle, that is, the connecting member 14 has a first end arranged along the vertical direction and a second end arranged along the horizontal direction, and the first end is perpendicular to the second end.

[0053] In this embodiment, the connecting member 1 is made of a connecting steel plate, and the size of the connecting steel plate is matched with the installation groove 16.

[0054] The first connecting member is the first connecting steel bar 8 embedded in the lightweight wall panel. The construction column 1 has a construction column steel reinforcement cage inside, and the first connecting steel bar 8 is fixedly connected to the construction column steel reinforcement cage. The second connecting member is the second connecting steel bar 10 embedded in the lightweight wall panel. The ring beam 2 has a ring beam steel reinforcement cage inside, and the second connecting steel bar 10 is fixedly connected to the ring beam steel reinforcement cage. The first connecting steel bar 8 is tied or welded to the construction column steel reinforcement cage, and the second connecting steel bar 10 is tied or welded to the ring beam steel reinforcement cage.

[0055] Conventional non-integrated prefabricated and post-installed lightweight wall panels usually use pipe clamps and U-shaped card connectors to connect the lightweight slats 3 to the construction column 1 or the ring beam 2. This application can also use pipe clamps and U-shaped card connectors for connection.

[0056] The end of the lightweight slat 3 connected to the concrete frame is provided with a drilling hole 9, and the drilling hole 9 is used to insert the first connecting steel bar 8 and the second connecting steel bar 10. After the connecting steel bars are placed in the drilling hole 9, the drilling hole 9 is filled with grouting material to fix the connecting steel bars in the drilling hole 9.

[0057] The joints between two adjacent lightweight slats 3 are sealed and connected by mortar. Multiple lightweight slats 3 are continuously fixed on the concrete frame to form precast wall panel components. The number of lightweight slats 3 is selected according to the wall design requirements. At the same time, the width of the construction column 1 can also be adjusted according to the wall size requirements. By integrally prefabricating the concrete frame and the lightweight slats 3 in the factory, the problems of low installation efficiency caused by multiple assemblies and repeated adjustments of the horizontal and vertical degrees during the on-site installation of the existing lightweight slats 3 are overcome. At the same time, the number of lightweight slats 3 and the width of the construction column 1 can be adjusted according to the design requirements, avoiding waste of plates caused by cutting.

[0058] The surface of the lightweight panel 3 is provided with a wire box groove and a wire pipe groove communicating with the wire box groove. The embedded wire box 5 is installed in the wire box groove, and the embedded wire pipe 6 is installed in the wire pipe groove. The embedded wire box 5 is connected to the embedded wire pipe 6. The wire box groove is opened on the lightweight wall panel. The wire pipe groove includes a main groove section and a connecting groove section. The main groove section is opened on the concrete frame, and the first end of the connecting groove section communicates with the wire box groove, and the second end of the connecting groove section communicates with the main groove section. The embedded wire pipe 6 extends from the lightweight panel 3 to the concrete frame along the position of the wire pipe groove, facilitating the subsequent installation of equipment pipelines. The embedded wire pipe 6 has a wiring end extending out of the precast wall panel member, and a wire pipe connecting comb joint 7 is arranged at the wiring end. By arranging the embedded wire box 5 and the embedded wire pipe 6 on the lightweight panel 3, the integration degree of the wall is improved, and the problem of chiseling on-site for installing equipment pipelines is avoided.

[0059] The present utility model further includes a preparation method for precast wall panel members, comprising the following steps:

[0060] Step 1: Design and manufacture a wall panel mold according to the size of the non-load-bearing wall panel, and determine the number of lightweight panels 3.

[0061] Since each lightweight panel 3 adopts a standard width size, the width of the construction column 1 outside the lightweight panel 3 can be adjusted to ensure that the number of lightweight panels 3 is an integer, without the need to cut the lightweight panels 3.

[0062] Step 2: Set reserved drill holes 9 on the upper and lower sides of the lightweight panel 3 and on the side in contact with the construction column 1. After placing the connecting steel bars 8 in the drill holes 9, fill the drill holes 9 with grouting material.

[0063] Step 3: Groove the lightweight panel 3 according to the design requirements for setting equipment pipelines.

[0064] Step 4: Assemble the processed lightweight panels 3 on the mold table, and seal the joints between the lightweight panels 3 with special mortar.

[0065] Step 5: After the lightweight panels 3 are assembled, start hoisting and placing the steel reinforcement cage, and bind and connect the connecting steel bars of the lightweight panels 3 with the steel reinforcement cage.

[0066] Among them, the steel reinforcement cage includes a construction column steel reinforcement cage and a ring beam steel reinforcement cage. The connecting steel bars of the lightweight panel 3 include a first connecting steel bar 8 and a second connecting steel bar 10 embedded in the lightweight panel 3. The first connecting steel bar 8 is fixedly connected to the construction column steel reinforcement cage, and the second connecting steel bar 10 is fixedly connected to the ring beam steel reinforcement cage.

[0067] Step 6: Arrange the embedded wire box 5 and the embedded wire pipe 6 at the preset positions of the lightweight panel 3 and the concrete frame according to the design requirements, and embed bolts 12 on the upper and lower sides and the left and right sides of the precast wall panel member.

[0068] Step 7: Pour the concrete frame around the lightweight slab 3. After pouring, cover it with a film for curing.

[0069] Among them, the concrete frame includes two construction columns 1 on the left and right sides of the lightweight slab 3, and two ring beams 2 on the upper and lower sides of the lightweight slab 3. When the width dimension of the required wall panel component is large, multiple construction columns 1 can be set.

[0070] Step 8: After curing, start demolding. Transfer the demolded precast wall panel component to the designated location for storage.

[0071] The present utility model also includes a construction method for precast wall panel components, which includes the following steps:

[0072] Step 1: Prepare precast wall panel components and construction and installation tools.

[0073] Before construction, prepare the precast wall panel components to be installed and the supporting installation tools and materials, including crowbars, wooden wedges, and fixing steel clips.

[0074] Step 2: Clean the construction working surface of the main structure floor 11 and determine the installation positioning line of the precast wall panel component.

[0075] Step 3: Lift and transfer the precast wall panel component to the installation position, hoist it to 600 mm above the working layer. The installer uses two towing ropes to hold the slab and slowly lower the precast wall panel component.

[0076] Step 4: Manually straighten the precast wall panel component, place it in place according to the preset installation positioning line, and install diagonal braces for temporary fixation to adjust the verticality of the wall panel.

[0077] Step 5: After the precast wall panel component is installed in place, fix and connect the lower part of the precast wall panel component to the main structure floor 11 through the reserved bolts 12, nuts 13, and connecting steel plates.

[0078] Among them, a bedding mortar 15 is filled between the bottom surface of the precast wall panel component and the main structure floor 11. The bedding mortar 15 is used to fill the gap between the precast wall panel component and the main structure floor 11.

[0079] Step 6: After the concrete of the vertical and horizontal components of the current layer of the main structure is poured and cured and the formwork is removed, fix and connect the upper part, left and right sides of the precast wall panel component to the concrete components of the building main structure through the reserved bolts 12, nuts 13, and connecting steel plates.

[0080] The precast wall panel component provided by the utility model prefabricates the concrete frame and the lightweight panel 3 integrally in the factory, overcoming the problem that the existing lightweight panel 3 needs to be assembled multiple times on site and the levelness and perpendicularity need to be adjusted repeatedly, resulting in low installation efficiency, and reducing the construction procedures. At the same time, the number of lightweight panels 3 and the width of the construction column 1 can be adjusted according to the design requirements, avoiding material waste caused by cutting.

[0081] By providing a buried wire box 5 and a buried wire pipe 6 on the lightweight panel 3, the integration degree of the wall is improved, and manual chiseling is no longer required during on-site installation, with high construction and installation efficiency and reliable quality.

[0082] Installation grooves 16 are provided at the upper and lower parts of the precast wall panel component for placing the connecting component 14 that connects the precast wall panel component to the building main structure, and can keep the wall surface flat after the precast wall panel component is connected to the building main structure. Connecting bolts 12 are buried at the lower part of the precast wall panel component, which is convenient for subsequent fixed connection with the connecting component 14.

[0083] The wall panel component prefabricated integrally by the lightweight panel 3 and the concrete frame has better integrity and a larger width dimension, and can realize that only one installation is required for one wall surface, solving the problems of complex procedures and low construction efficiency caused by the small width of the existing lightweight panel 3 and the need for multiple assemblies and repeated adjustments during installation.

[0084] Since the main material of the wall panel component is the lightweight panel 3, the weight of the wall panel component is less than that of the ordinary concrete wall panel component and the conventional lightweight concrete wall panel component of the same size, reducing the construction hoisting and installation difficulty.

[0085] The construction method of the precast wall panel component provided by the utility model hoists the integrally precast wall panel component to the installation position, and only needs to fix the end of the precast wall panel component to the building main structure to complete the installation of the precast wall panel component. The installation process is fast and convenient, improving the construction efficiency and saving labor costs.
