Description

Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, specifically relating to modular wall panels. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in factories, transported to the construction site, and assembled and installed on-site using reliable connection methods.

[0003] In existing technologies, considering that steel structures have advantages such as high material strength, good plasticity and toughness, recyclability, and environmental friendliness, their application in building structures can reduce structural self-weight, improve structural seismic performance, and speed up construction. As a result, their use is increasing.

[0004] Those skilled in the art fix steel beams, steel columns, and floor slabs to form cavities. The walls are modular walls processed in the factory. After the walls are processed, they are transported to the construction site and then fixed to the steel beams and floor slabs by metal components. At this point, how to quickly connect the modular walls and metal components is a technical problem that those skilled in the art need to solve. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a modular wall panel. When the modular wall is processed in the factory, through bolts are fixed to the frame, so that the through bolts are pre-set in the modular wall panel. After the modular wall is processed and transported to the construction site, the through bolts on the modular wall can be passed through the installation holes of the metal components on the steel beams and floor slabs. Then, the fixing nuts are screwed into the through bolts, so that the modular wall can be quickly installed on the steel beams and floor slabs, improving construction efficiency, saving construction costs, and at the same time not damaging the structure of the modular wall, so that it has sufficient load-bearing capacity.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A modular wall panel is characterized by comprising a frame, through bolts, an insulation layer, and a surface layer. The frame has a first mounting surface and a second mounting surface. The frame has an inner cavity, and the insulation layer is disposed in the inner cavity. The through bolts are fixed to the frame along the height direction. The frame has a first through hole, through which the through bolts pass and extend a set length out of the frame. The surface layer is fixed to the first mounting surface and the second mounting surface, respectively.

[0008] Furthermore, the frame includes a main keel, which forms a groove, and a connector is installed in the groove to fix the two main keels together.

[0009] Furthermore, the main keel uses keel one, keel two, and keel three. Keel one has a C-shaped cross-section, keel two has an arc-shaped cross-section, and keel three has a tongue-and-groove cross-section. The frame splicing method is as follows: the main keel in both the length and width directions of the frame uses keel one; or the main keel in the length direction of the frame uses keel two, and the main keel in the width direction of the frame uses keel one; or the main keel in the length direction of the frame uses keel three, and the main keel in the width direction of the frame uses keel one.

[0010] Furthermore, the connector is fixed with a sleeve, the sleeve has a through hole running vertically through it, and the connector has a second through hole, through which a through bolt passes.

[0011] Furthermore, the connector includes a horizontal plate one and a vertical plate two, with plate two fixed between plate one, and a sleeve fixed between the two plates one. Plate one is fixed to the main keel by fasteners.

[0012] Furthermore, the connector includes a horizontal plate three, a sleeve fixed between two plates three, and the plates three are fixed by fasteners and the main keel.

[0013] Furthermore, the through bolt is equipped with a nut, which is limited at one mounting surface. The second mounting surface is equipped with a washer, and the through bolt passes through the through hole three of the washer. The end of the through bolt is limited on the washer.

[0014] Furthermore, a liner is fixed to the mounting surface, and the liner has an opening, with a nut placed in the opening.

[0015] Furthermore, the surface layer includes a base layer, which is made of calcium silicate board. The calcium silicate board is fixed on the mounting surface, and through bolts pass through the calcium silicate board, which covers the insulation layer.

[0016] Furthermore, the surface layer includes a waterproof and breathable layer, which is fixed on the second mounting surface and covers the insulation layer.

[0017] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0018] This invention involves fixing through bolts to the frame during the factory fabrication of modular walls. These through bolts are pre-installed within the modular wall panels. After fabrication, the modular walls are transported to the construction site. The through bolts are then passed through the mounting holes in the metal components of the steel beams and floor slabs. By screwing in the fixing nuts, the modular walls can be quickly installed on the steel beams and floor slabs, improving construction efficiency, saving costs, and preserving the structure of the modular walls to ensure sufficient load-bearing capacity.

[0019] Meanwhile, the modular wall is equipped with an insulation layer to improve its thermal insulation performance. Attached Figure Description

Detailed Implementation

[0043] like Figures 1 to 17 The image shown is an embodiment of this utility model.

[0044] Modular wall panels, including frame 1, through bolts 4, insulation layer and surface layer.

[0045] The frame 1 has an installation surface 1d and an installation surface 1e. The frame 1 has an inner cavity 1c, and the insulation layer is located in the inner cavity 1c. The insulation layer of this utility model is made of rock wool 12, which is a fireproof and heat-insulating material with excellent waterproof and high-temperature resistance properties.

[0046] This utility model uses four main keels to form a rectangular frame 1, which has a slot 1b.

[0047] The two main keels are fixedly connected by connector 2. Connector 2 is installed in slot 1b and supports the main keel, making the main keel less prone to deformation.

[0048] The connector 2 is fixed with a sleeve 2c. The sleeve 2c has a through hole 2e. The sleeve 2c supports the entire connector 2 and improves the strength of the connector 2.

[0049] This utility model provides three embodiments for the connector 2:

[0050] (1) Example 1 of connector: Connector 2 includes a horizontal plate 2b and a vertical plate 2a. Plate 2a is fixed between plates 2b, and sleeve 2c is welded between plates 2b. Plate 2b has a through hole 2d. Example 1 of connector manufacturing is carried out in two ways: 1) Connector 2 is directly formed by stamping, making it an integral structure, which is convenient to process, fast to form, and has good strength. 2) Plate 2b and plate 2a are fixed by welding seam 3, which can produce connector 2 of a certain size. At the same time, plates 2b and plate 2a can be cut and drilled separately, improving the processing quality.

[0051] When connector 2 is fixedly connected to the main keel, connector 2 is fixed to the main keel by fasteners. Both plate 2b and the main keel of this utility model are provided with positioning holes 15. Self-tapping screws 8 are used as fasteners. When installing the self-tapping screws 8, a pin is inserted into the positioning holes 15 of plate 2b and the main keel, and then the self-tapping screws 8 are placed on the main keel and plate 2b. Then the pin is removed.

[0052] (2) Example 2 of connector: The connector includes a horizontal plate 2f, which has a through hole 2d. A sleeve 2c is welded between the two plates 2f. The plates 2f are fixed by self-tapping screws 8 and the main keel.

[0053] (3) Example 3 of connector: The connector includes a horizontal plate 2f, which has a through hole 2d. Both plates 2f are fitted with rubber sleeves 2g. The rubber sleeves 2g are elastically inserted into the pipe hole 2e of the sleeve 2c. The rubber hole of the rubber sleeve 2g is used to install the through bolt 4. The plates 2f are fixed to the main keel by self-tapping screws 8.

[0054] In Embodiment 1 of this utility model, the through bolt 4 is installed using the connector embodiment 1. The main keel has a through hole 1, through bolt 4 passes through through hole 1, pipe hole 2e, and through hole 2d. Sleeve 2c limits the through bolt 4 and improves its load-bearing capacity. The through bolt 4 extends a predetermined length beyond the mounting surface 1d so that it can extend a certain length beyond the entire modular wall panel, providing sufficient length for connecting the steel beam and metal components on the floor slab.

[0055] The through bolt 4 is equipped with a nut 5, which is positioned at the mounting surface 1d. The mounting surface 1e is equipped with a washer 6. The through bolt 4 passes through the through hole 3 of the washer 6, and the end 41 of the through bolt 4 is positioned on the washer 6, thus ensuring that the through bolt 4 is securely attached to the frame 1 along its height. A liner 7 is fixed to the mounting surface 1d. The liner 7 has an opening 71, in which the nut 5 is placed, resulting in a concealed design.

[0056] One of the surface layers of this utility model includes a base layer, which is a calcium silicate board 10. Butyl tape 9 is applied to the mounting surface 1d. Butyl tape 9 has strong adhesion, high tensile strength, and good elongation. The calcium silicate board 10 is fixed to the butyl tape 9, ensuring a sealed and fixed installation. Simultaneously, the calcium silicate board 10 is placed on the liner 7 to prevent damage to the calcium silicate board 10 from the nut 5. Through bolts 4 pass through the calcium silicate board 10. Foaming agent is applied to the calcium silicate board 10 and the frame 1. Rock wool 12 is fixed to the calcium silicate board 10 and the frame 1 using the foaming agent, covering the rock wool 12. The calcium silicate board 10 is fixed to a secondary keel 11 using self-tapping screws 8. The secondary keel 11 has round holes 11a through which the self-tapping screws 8 pass. The secondary keel 11 is used to fix the wall panels, forming an exterior wall system.

[0057] Another surface layer includes a waterproof and breathable layer 14. Double-sided adhesive tape 13 is applied to the second mounting surface 1e, and the waterproof and breathable layer 14 is fixed to the second mounting surface 1e by the double-sided adhesive tape 13, covering the rock wool 12. The waterproof and breathable layer 14 uses a waterproof and breathable membrane. The main functions of the waterproof and breathable membrane include enhancing the water tightness of the building, improving thermal insulation and energy-saving effects, shortening the construction period, and improving the living environment.

[0058] In Example 1, the frame uses keel 1a in both the length and width directions. The cross-section of keel 1a is C-shaped, and four keels 1a are fixed to form the frame.

[0059] like Figure 18 and Figure 19 The image shown is a second embodiment of this utility model.

[0060] Based on the structure of Embodiment 1, Embodiment 2 of this utility model designs the main keel of the frame: the main keel in the length direction of the frame is keel 31f, the main keel in the width direction of the frame is keel 1a, the cross section of keel 1a is C-shaped, the cross section of keel 31f is tongue and groove shaped, and the two keels 31f and the two keels 1a are fixed to form the frame.

[0061] like Figure 20 and Figure 21 The image shown is Embodiment 3 of this utility model.

[0062] Based on the structure of Embodiment 1, Embodiment 3 of this utility model designs the main keel of the frame: the main keel in the length direction of the frame is keel 2 1g, and the main keel in the width direction of the frame is keel 1a. The cross section of keel 1a is C-shaped, and the cross section of keel 2 1g is bow-shaped. The two keels 2 1g and the two keels 1a are fixed to form a frame.

[0063] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
