Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a reinforcement structure and method for hollow sandwich panels. Background Technology

[0002] Due to its large span and hollow beams, hollow sandwich slab structures, with their unique structural shape, are prone to serious adverse effects on the overall structure if quality problems such as formwork displacement or bulging occur during concrete pouring. Therefore, high requirements are placed on the success of on-site construction in one go.

[0003] Traditional template reinforcement methods are inefficient, and because the reinforcement of each unit grid is independent, the forming quality is difficult to guarantee, which can easily lead to quality problems such as beam twisting and grid deformation, seriously affecting the appearance and quality of the structure. Summary of the Invention

[0004] The primary technical problem to be solved by this invention is to provide a reinforcement structure for a hollow sandwich panel.

[0005] Another technical problem to be solved by the present invention is to provide a method for reinforcing hollow sandwich panels.

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

[0007] The first aspect of the technical solution of the present invention provides a reinforcement structure for a hollow sandwich panel, comprising multiple unit grids, each of the unit grids comprising an upper rib beam, a lower rib beam, and a shear key connecting the upper rib beam and the lower rib beam;

[0008] The multiple unit grids are interconnected to form an upper rib beam layer, a shear key layer, and a lower rib beam layer; wherein, any two adjacent shear keys in the shear key layer are connected and reinforced by prefabricated reinforcement components, so that the shear key layer is connected into a whole.

[0009] Furthermore, the prefabricated reinforcement components include at least square and round reinforcement components, internal corner reinforcement components, and U-shaped reinforcement components;

[0010] The square and round reinforcement component is connected to the middle region of two adjacent shear keys for middle reinforcement;

[0011] The corner reinforcement component is installed at the corner of the shear key for corner reinforcement.

[0012] The U-shaped reinforcement is positioned at the external corner of the shear key for corner reinforcement.

[0013] Furthermore, multiple upper clamps are spaced apart on the upper rib beam layer to fix the relative position of the upper rib beam layer.

[0014] Furthermore, the upper clamp adjacent to the shear key among the plurality of upper clamps is inclined to avoid the shear key, while the remaining upper clamps are all vertically arranged.

[0015] Furthermore, multiple lower clamps are spaced apart on the lower rib beam layer to fix the relative position of the lower rib beam layer.

[0016] Furthermore, it also includes multiple diagonal reinforcement components;

[0017] The diagonal reinforcement is inclined, and the first end of the diagonal reinforcement is connected to the connection between the upper rib beam layer and the shear key layer, and the second end of the diagonal reinforcement is connected to the connection between the lower rib beam layer and the shear key layer.

[0018] A second aspect of the present invention provides a method for reinforcing the above-mentioned hollow sandwich panel reinforcement structure, comprising the following steps:

[0019] Based on the construction drawings, determine the required reinforcement dimensions for different types of unit grids, and prefabricate the reinforcement components according to the stated reinforcement dimensions;

[0020] The lower rib beams of multiple unit grids are connected and fixed in sequence to form a lower rib beam layer;

[0021] Two adjacent shear keys in multiple unit grids are connected and fixed by the prefabricated reinforcement components;

[0022] Multiple unit grid upper ribs are connected and fixed sequentially to form an upper rib layer.

[0023] Furthermore, the step of sequentially connecting and fixing the lower rib beams of multiple unit grids to form a lower rib beam layer specifically includes:

[0024] On the lower rib beam between two adjacent shear keys, lower clamps are arranged at equal intervals of not less than 600mm, such that the lower clamps closest to the shear keys are inclined, while the remaining lower clamps are vertical.

[0025] Furthermore, the step of connecting and fixing two adjacent shear keys in multiple unit grids through the prefabricated reinforcement specifically includes:

[0026] The square and round reinforcement components are connected to the middle area of ​​two adjacent shear keys for central reinforcement.

[0027] The internal corner reinforcement component is set at the internal corner position of the shear key for internal corner reinforcement;

[0028] The U-shaped reinforcement is placed at the external corner of the shear key for corner reinforcement;

[0029] The square and round reinforcement members, the inside corner reinforcement members, and the U-shaped reinforcement members together constitute the prefabricated reinforcement members.

[0030] Furthermore, the step of sequentially connecting and fixing the upper ribs of multiple unit grids to form an upper rib layer specifically includes:

[0031] On the upper rib beam between two adjacent shear keys, upper clamps are arranged at equal intervals of not less than 600mm, such that the upper clamps closest to the shear keys are inclined, while the remaining upper clamps are vertical.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] The reinforcement structure for hollow sandwich panels in this invention, in practical application, connects all unit grids into a whole through prefabricated reinforcement components, improving the overall stability of the formwork system and effectively solving the problem of difficulty in ensuring the reinforcement quality of hollow sandwich panel formwork. Furthermore, the combination of prefabricated reinforcement components and beam clamps not only simplifies the construction process and shortens the cycle, but also increases reliability, greatly improving construction efficiency. In addition, the number of prefabricated reinforcement components can be increased or decreased as needed to meet the construction requirements of different construction scenarios.

[0041] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0042] like Figure 1 As shown, this is a reinforcement structure for a hollow sandwich panel provided in an embodiment of the present invention. The reinforcement structure includes multiple unit grids 10. Figure 2 As shown, each unit grid 10 includes an upper rib beam 101, a lower rib beam 102, and a shear key 103 connecting the upper rib beam 101 and the lower rib beam 102.

[0043] In this embodiment, multiple unit grids 10 are interconnected to form an upper rib beam layer, a shear key layer, and a lower rib beam layer. It is understood that the upper rib beam layer is formed by multiple upper rib beams 101, the shear key layer by multiple shear keys 103, and the lower rib beam layer by multiple lower rib beams 102. In the shear key layer, any two adjacent shear keys are connected and reinforced using prefabricated reinforcement components, thus connecting the shear key layer into a unified whole. Therefore, during construction, the prefabricated reinforcement components can be used to achieve stable connections between the various unit grids 10, improving the overall stability of the hollow sandwich panel system and effectively solving the problem of difficulty in ensuring the reinforcement quality of hollow sandwich panels.

[0044] Specifically, such as Figure 2 and Figure 3 As shown, in this embodiment, the prefabricated reinforcement components include at least a square-round reinforcement component 11, a corner reinforcement component 12, and a U-shaped reinforcement component 13. The square-round reinforcement component 11 can be a square column or a cylinder, and it connects to the middle region of two adjacent shear keys 103 for central reinforcement. The corner reinforcement component 12 can be L-shaped and is positioned at the inside corner of the shear key 103 for inside corner reinforcement. The U-shaped reinforcement component 13 is positioned at the outside corner of the shear key 103 for outside corner reinforcement. It is understood that the specific shapes of the square-round reinforcement component 11, the corner reinforcement component 12, and the U-shaped reinforcement component 13 in this embodiment are only a preferred implementation. In other embodiments, the specific shapes of the square-round reinforcement component 11, the corner reinforcement component 12, and the U-shaped reinforcement component 13 can be adaptively adjusted as needed to adapt to unit grids 10 of different specifications or sizes. Furthermore, the number of prefabricated reinforcement components can also be increased or decreased as needed to meet the construction requirements of different construction scenarios.

[0045] In this embodiment, multiple clamps are provided on both the upper and lower rib beam layers to further improve the overall stability of the hollow sandwich panel system. Specifically, as shown... Figure 4 As shown, lower clamps 104 are arranged at equal intervals of not less than 600 mm on the lower rib beam between two adjacent shear keys. The lower clamps 104 adjacent to the shear key 103 are inclined, while the remaining lower clamps 104 are vertical. Similarly, upper clamps 105 are arranged at equal intervals of not less than 600 mm on the upper rib beam between two adjacent shear keys 103. The upper clamps 105 adjacent to the shear key 103 are inclined, while the remaining upper clamps 105 are vertical. It is understood that the structural forms of the lower clamps 104 and upper clamps 105 can be the same or different, and the appropriate form can be selected according to actual needs.

[0046] Furthermore, in this embodiment, the reinforcement structure also includes multiple diagonal reinforcement members. Specifically, the diagonal reinforcement members are columnar (e.g., cylindrical) and inclined, with the first end connected to the connection between the upper rib beam layer and the shear key layer, and the second end connected to the connection between the lower rib beam layer and the shear key layer. Thus, the diagonal reinforcement members, in conjunction with the upper and lower rib beam layers, form a triangular stable structure, improving both the overall stability of the reinforcement structure and its shear resistance, thereby increasing the structural strength.

[0047] like Figure 5 As shown, based on the above embodiments, this invention also provides a method for reinforcing hollow sandwich panels, specifically including steps S1-S4:

[0048] S1: Based on the construction drawings, determine the required reinforcement dimensions for different types of unit mesh 10, so as to prefabricate the reinforcement components according to the reinforcement dimensions;

[0049] Specifically, based on the type of unit mesh 10, the specific dimensions of the square and round reinforcement 11, the inside corner reinforcement 12, and the U-shaped reinforcement 13 are determined respectively, and the square and round reinforcement 11, the inside corner reinforcement 12, and the U-shaped reinforcement 13 are prefabricated according to the specific dimensions of each reinforcement.

[0050] S2: Connect and fix the lower rib beams of multiple unit grids 10 in sequence to form a lower rib beam layer;

[0051] Specifically, on the lower rib beam 102 between two adjacent shear keys, lower clamps 104 are arranged at equal intervals of not less than 600mm, such that the lower clamps 104 adjacent to the shear key 103 are inclined, while the remaining lower clamps 104 are vertical.

[0052] S3: Connect and fix two adjacent shear keys in multiple unit grids using prefabricated reinforcement components;

[0053] Specifically, the square-round reinforcement member 11 is connected to the middle area of ​​two adjacent shear keys 103 for middle reinforcement; the inside corner reinforcement member 12 is set at the inside corner of the shear key 103 for inside corner reinforcement; and the U-shaped reinforcement member 13 is set at the outside corner of the shear key 103 for outside corner reinforcement.

[0054] S4: Connect and fix the upper rib beams of multiple unit grids in sequence to form an upper rib beam layer.

[0055] Specifically, on the upper rib beam 101 between two adjacent shear keys 103, upper clamps 105 are arranged at equal intervals of not less than 600mm, such that the upper clamp 405 closest to the shear key 103 is inclined, while the other upper clamps 105 are vertically arranged.

[0056] In summary, the reinforcement structure and method for hollow sandwich panels provided by the embodiments of the present invention have the following beneficial effects:

[0057] 1. By connecting all unit grids into a whole through prefabricated reinforcement components, the overall stability of the template system is improved, and the problem of difficulty in ensuring the quality of hollow sandwich panel template reinforcement is effectively solved.

[0058] 2. The method of combining prefabricated reinforcement components with beam clamps not only simplifies the construction process and shortens the cycle, but also increases reliability and greatly improves construction efficiency.

[0059] 3. The number of prefabricated reinforcement components can be increased or decreased as needed to meet the construction requirements of different construction scenarios.
