Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated concrete wall panels, in particular to a modular prefabricated concrete wall panel. Background Art

[0002] With the rapid development of the construction industry, precast concrete wall panels have been widely used in various construction projects due to their advantages such as high construction efficiency and stable quality.

[0003] Traditional precast concrete wall panels have high material density and overall weight, resulting in high transportation and lifting costs. At the same time, they also place high demands on mechanical equipment at the construction site, increasing the difficulty of construction and the economic burden. During the production and use process, unreasonable internal structural design of the wall panels may lead to local stress concentration in the wall, thereby causing deformation or cracking, affecting the overall strength and service life of the wall. Although some wall panels try to increase their strength by adding steel bars or other supporting structures, these designs often make the production process more complicated, increase manufacturing costs, and also reduce construction efficiency.

[0025] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0026] Please refer to Figure 1-Figure 8 The embodiment of the utility model provides a modular prefabricated concrete wall panel, including a base 1, which is made of concrete casting.

[0027] There are multiple groups of cylindrical weight-reducing cavities 4 distributed inside the base 1. The weight-reducing cavities 4 are positioned by the internal reinforcement mechanism 2. The weight-reducing cavities 4 are vertically distributed to the internal reinforcement mechanism 2. Two groups of internal reinforcement mechanisms 2 can be used to position the weight-reducing cavities 4, and at the same time, the internal reinforcement mechanism 2 and the weight-reducing cavities 4 can be cast inside the base 1 by auxiliary concrete pouring.

[0028] The cross-section of the weight-reducing cavity 4 is a regular hexagon. The hexagonal structure provides an optimal space filling rate, making the concrete distribution more even. Its outer surface is provided with a spiral groove 41 combined with the concrete. The design of the spiral groove 41 increases the contact area with the concrete and effectively prevents stratification.

[0029] Among them, the internal reinforcement mechanism 2 includes transverse ribs 21, auxiliary ribs 22, oblique ribs 23 and extended ribs 24. The transverse ribs 21, auxiliary ribs 22 and oblique ribs 23 are welded into a triangular bracket. There are two groups of triangular brackets. The welding points of the two groups of triangular brackets are connected with extended ribs 24. The triangular structure improves the bending stiffness. The two groups of triangular brackets are connected by the extended ribs 24 to form a spatial truss system. The extended ribs 24 not only enhance the integrity but also facilitate connection with other parts of the wall panel, so that the weight of the reinforcement mechanism is reduced while the impact resistance is enhanced. The standardized structure of the triangular bracket reduces the production cost, perfectly realizing the engineering requirements of lightweight, high strength and easy installation.

[0030] An arc-shaped fixing sleeve 3 is provided at the end of the extension rib 24 , and the fixing sleeve 3 is fixed to one side of the weight-reducing cavity 4 . Two groups of fixing sleeves 3 are respectively located on both sides of the weight-reducing cavity 4 , thereby completing the fixation of the weight-reducing cavity 4 .

[0031] Furthermore, the upper side of each weight-reducing cavity 4 is fixed by a positioning block 8 , and the plurality of positioning blocks 8 are connected in series by positioning ribs 9 . After concrete pouring, the positioning ribs 9 and the positioning blocks 8 fix the upper end of the weight-reducing cavity 4 .

[0032] In order to improve the thermal insulation performance, an insulation component is installed on the inner side of the weight-reducing cavity 4. The insulation component includes an insulation layer 5 located in the weight-reducing cavity 4. The insulation layer 5 is made of glass fiber. The excellent thermal insulation performance of glass fiber reduces the overall thermal conductivity of the wall panel and significantly improves the thermal insulation effect.

[0033] The insulation layer 5 is internally provided with a reinforcing layer 6 which adopts a hard polyurethane insulation core, which can effectively resist the lateral pressure during concrete pouring. The hard polyurethane insulation core and the glass fiber insulation layer 5 form a composite insulation system, and the thermal conductivity is further reduced, thereby achieving a double insulation effect.

[0034] Support frames 7 are provided at both ends of the interior of the weight-reducing cavity 4 , and the support frames 7 are used to support the interior of the weight-reducing cavity 4 , thereby improving the anti-deformation capability of the weight-reducing cavity 4 .

[0035] The base 1 is wrapped around a pair of connecting frames 10 and a pair of connecting frames 11. The cross-sections of the connecting frames 10 and 11 are trapezoidal structures. Both ends of the connecting frame 10 are provided with convex connecting heads 13, and both ends of the connecting frame 11 are provided with concave connecting grooves 14. The connecting heads 13 are plugged into the connecting grooves 14 to achieve modular and rapid assembly of wall panels. The convex-concave plug-in structure ensures accurate positioning and firm connection.

[0036] A sealing gasket 15 is provided on one side of the connecting head 13. The sealing gasket 15 is designed to effectively prevent water seepage at the joints. A water guide groove 12 is opened on the inclined surface of the connecting frame 11. The water guide groove 12 can discharge accumulated water in time to avoid erosion, thereby forming multiple protections against leakage as a whole. At the same time, the standardized interface greatly improves the construction efficiency, and different wall panel units can be seamlessly connected, which not only ensures the integrity of the building appearance, but also improves the waterproof performance and assembly convenience.

[0037] The connecting frame 10 and the connecting frame 2 11 are connected to the base 1 by adopting an integrated pre-embedded anchor welding process. First, a high-strength threaded sleeve is pre-embedded when the concrete base 1 is poured. After the mold is removed, the anchor bolt is screwed into the sleeve. Then, matching bolt holes are processed on the mounting surfaces of the connecting frame 10 and the connecting frame 2 11. After mechanical fixation with bolts, continuous fillet welds are performed along the inner side of the frame at the joint with the base 1.

[0038] In summary, a modular prefabricated concrete wall panel according to an embodiment of the utility model has the following working principle: by setting a cylindrical weight-reducing cavity 4 in the base 1, combined with an internal reinforcement mechanism 2 and a support frame 7, light weight and high strength are achieved; the thermal insulation layer 5 and the reinforcement layer 6 improve the thermal insulation performance, and the anti-deformation ability is enhanced; the connecting frame 10 and the connecting frame 2 11 are plug-in matched through a convex connecting head 13 and a concave connecting groove 14 to ensure modular rapid assembly; the sealing gasket 15 and the water guide groove 12 provide multiple waterproof protections.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
