Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a reinforcement device for the edge formwork of the cast-in-place layer of prefabricated beams in prefabricated buildings. Background Technology

[0002] The construction of traditional reinforced concrete cast-in-place structures cannot fully meet the requirements of industrial development in terms of efficiency, cost, environmental protection, and quality control. The development of prefabricated buildings, however, provides the construction industry with new solutions and a direction for transformation.

[0003] In prefabricated buildings, precast beams must retain a portion of the cast-in-place concrete structure to ensure the integrity and stability of the overall structure. At the same time, they work with side formwork to form a cast-in-place space. When precast beams are placed on the exterior facade of a building, the side formwork can only be supported on one side and requires additional fixing devices to secure them. In existing technologies, the side formwork is usually reinforced by pre-drilling tie holes in the precast beam and then passing screws through the tie holes. This operation is complex and costly. In addition, inadequate sealing of the pre-drilled tie holes can easily lead to the risk of leakage in the exterior walls. Utility Model Content

[0027] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a reinforcement device 1 for the side formwork of the cast-in-place layer of precast beam in an assembled building. The reinforcement device 1 is used to fix the side formwork 2, wherein the side formwork 2 is disposed on one side of the precast beam 3 and partially abuts against the side wall of the precast beam 3.

[0029] like Figure 1 As shown, the reinforcement device 1 includes a support member 11, multiple pressing members 12, multiple strip-shaped connectors 13, and multiple rigid connecting ropes 14. The support member 11 and the pressing members 12 are both strip-shaped structures. The support member 11 extends along the length of the precast beam 3 and is supported between the inner side of the side mold 2 and the outer reinforcing bars 31 on the outer side of the precast beam 3, ensuring the side mold 2 is vertical. The multiple pressing members 12 are spaced vertically on the outer side of the side mold 2 and extend along its length. The multiple strip-shaped connectors 13 are spaced along the length of the side mold 2 on the outer side of the pressing members 12. Each strip-shaped connector 13 simultaneously connects to multiple pressing members 12 to form a continuous pressure surface. Each strip-shaped connector 13 corresponds to at least one rigid connecting rope 14. One end of the rigid connecting rope 14 is connected to the strip-shaped connector 13, and the other end is connected to the outer reinforcing bars 31 of the precast beam 3. Tensile force is used to press the pressing members 12 against the side mold 2. By placing the support member 11 between the side formwork 2 and the external reinforcing bar 31, and cooperating with the pressing member 12, the strip connector 13, and the rigid connecting rope 14, the side formwork 2 can be quickly positioned and fixed, greatly simplifying the construction steps and significantly improving construction efficiency. At the same time, it reduces the mold processing cost required for reserving tie holes in the precast beam 3, and avoids the additional materials required for sealing the tie holes, effectively reducing the overall construction cost.

[0030] Since there is no need to drill tie rod holes in the precast beam 3, the risk of leakage in the exterior wall due to inadequate sealing of the pre-drilled tie rod holes is completely eliminated, ensuring the waterproof performance of the building facade, improving building quality, and extending the building's service life. Furthermore, after the post-cast concrete pouring is completed, this reinforcement device 1 can be disassembled simply by cutting the external steel wire connecting rope, and the main components can be reused, further saving resources. Moreover, the method of connecting the rigid connecting rope 14 to the external reinforcing steel bar 31 allows for flexible adjustment of the fixing position and force according to different specifications of the precast beam 3 and the side formwork 2, making it highly versatile and widely applicable.

[0031] like Figure 1 and Figure 2 As shown, there are two pressing members 12. The two pressing members 12 are arranged vertically and vertically along the side mold 2. The top of one pressing member 12 is flush with the top of the side mold 2, and the bottom of the other pressing member 12 is flush with the bottom of the side mold 2. This can form a stable symmetrical pressing structure at the top and bottom of the side mold 2, preventing the side mold 2 from tilting or displacing due to uneven force during concrete pouring, and significantly improving the stability of the side mold 2.

[0032] In this embodiment, the cross-section of the pressure-retaining member 12 is rectangular, and the length direction of the pressure-retaining member 12 is consistent with the length direction of the side mold 2. The rectangular cross-section of the pressure-retaining member 12 increases the contact area between the pressure-retaining member 12 and the side mold 2, enabling more uniform pressure transmission and preventing damage to the side mold 2 due to local stress concentration. The consistency in the length direction ensures that the pressure-retaining member 12 can provide continuous and stable pressure along the length of the side mold 2, enhancing the overall reinforcement effect and ensuring the quality of the cast-in-place layer. The pressure-retaining member 12 is made of wood, which is low-cost, lightweight, and easy to process and install, reducing the cost and construction difficulty of the reinforcement device 1. The surface of the pressure-retaining member 12 is coated with an epoxy resin waterproof coating. This coating effectively prevents the wooden pressure-retaining member 12 from deforming or rotting due to moisture, extending its service life. It also prevents the moisture of the wood from affecting the fixing effect of the side mold 2, ensuring the long-term stable operation of the reinforcement device 1.

[0033] In this embodiment, the upper and lower ends of the strip connector 13 extend 5-10cm outward from the pressing member 12, which facilitates the connection operation of the rigid connecting rope 14. At the same time, the strip connector 13 is provided with a first anti-slip texture, which increases the friction between the rigid connecting rope 14 or other components, prevents slippage during the connection process, ensures the overall structure of the reinforcement device 1 is stable, and improves construction safety.

[0034] The spacing between two adjacent strip connectors 13 is 30-45cm, and they are evenly distributed along the length of the side mold 2. This ensures the uniformity of the force on the pressing component 12, avoiding insufficient local support for the side mold 2 due to excessive spacing, or material waste and complicated construction due to insufficient spacing. The even distribution ensures that the side mold 2 is subjected to balanced pressing force in the length direction, further improving the fixing accuracy of the side mold 2 and the construction quality of the cast-in-place layer.

[0035] In this embodiment, the strip connector 13 is preferably made of 16mm diameter threaded steel, which is readily available at construction sites, effectively reducing construction costs and improving material turnover efficiency. The ribbed structure on the surface of the threaded steel can form a stable mechanical engagement with the pressing member 12 and the rigid connecting rope 14, further enhancing the reliability of the connection. It should be noted that those skilled in the art can choose strip-shaped metal components with sufficient rigidity, such as angle steel or square steel pipe, or other materials that meet the same mechanical performance requirements to replace the threaded steel strip connector 13, depending on actual construction needs and material supply. Such substitutions should all fall within the protection scope of this patent's technical solution.

[0036] In this embodiment, the rigid connecting rope 14 is a galvanized steel wire rope. The galvanizing treatment effectively prevents the steel wire rope from rusting and corroding, extends its service life, and ensures the reliability of the connection during long-term use. The diameter of the steel wire rope is 3-6mm, which ensures that the steel wire rope has sufficient strength to withstand the tension required to fix the side mold 2, without increasing the construction difficulty and cost due to excessive thickness, thus achieving a balance between strength and economy.

[0037] like Figure 1 As shown, the support member 11 has a rectangular cross-section, which provides a stable support structure and ensures stable force transmission between the support member 11 and the side formwork 2 and the external reinforcing steel 31. A second anti-slip texture is provided on the side of the support member 11 that contacts the side formwork 2. This second anti-slip texture increases the friction with the side formwork 2, preventing displacement or sliding of the support member 11 during construction and ensuring that the side formwork 2 remains vertical, providing a reliable positioning foundation for the cast-in-place layer construction.

[0038] To prevent grout leakage, a sealing strip is installed between the side formwork 2 and the side wall of the precast beam 3. The sealing strip can effectively fill the gap between the two, prevent concrete grout from seeping in, and avoid appearance defects and quality problems of the cast-in-place layer caused by grout leakage.
