Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically a support frame for large-span construction. Background Technology

[0002] In today's construction industry, most construction teams and companies typically use traditional steel pipe scaffolding to erect full-span scaffolding. However, this traditional steel pipe scaffolding has some limitations in practical applications. Specifically, due to insufficient precision in the interlocking of the steel pipes, it often fails to provide adequate support strength and stability when erecting support platforms on higher floors or over larger spans. This not only affects construction efficiency and safety but may also pose a potential threat to the stability and quality of the entire building structure.

[0003] Therefore, to address this challenge, there is an urgent need to develop a new type of support frame structure. This new support frame structure should possess higher overall stability and stronger support strength to meet the demands of large-span construction in modern building projects. By employing advanced design and materials, this new support frame can effectively solve the problems of insufficient stability and strength faced by traditional steel pipe scaffolding in high-distance and large-span construction. This will not only improve construction efficiency but also ensure the safety of the construction process and the quality of the final building. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A support frame for large-span construction includes a bracket, vertical rods, a base, horizontal rods, pins, and pins for fixing the vertical rods and horizontal rods. The bracket, vertical rods, and base are sequentially spliced ​​from top to bottom using a polygonal sleeve structure. A vertical rod buckle is provided in the middle area of ​​the vertical rod. The horizontal rods are connected to the vertical rods through the vertical rod buckle. The pins pass through the mounting holes at the ends of the horizontal rods and the mounting holes of the vertical rod buckles, connecting the vertical rods and horizontal rods.

[0007] The bracket includes a support plate, a lifting rod, an adjusting nut, and a bracket connecting block; the support plate is rotatably mounted on the upper end of the lifting rod; the lifting rod further includes a fixing nut, a sliding groove, and a limiting block; the sliding groove is arranged along the axial direction of the lifting rod; the bracket connecting block is a polygonal cylinder connected to the upper end of the vertical rod, with a circular hole at its center, and a raised ridge provided along the axial direction on the inner wall of the circular hole; the sliding groove and the raised ridge provided on the inner wall of the bracket connecting block slide in fit; the limiting block is located at the lower end of the lifting rod and is an integral part of the lifting rod.

The center of the support plate is provided with a stepped hole that mates with the lifting rod. The smaller hole in the stepped hole mates with the small shaft diameter area at the upper end of the lifting rod, and the larger diameter hole in the stepped hole mates with the fixing nut. The fixing nut is used to limit the support plate in the axial direction of the lifting rod and to allow the support plate to rotate at the top of the lifting rod.

[0010] Preferably, the diameter of the limiting block is larger than the diameter of the central hole of the bracket connecting block.

[0011] Preferably, the vertical rod includes: an upper connecting cylinder, a vertical rod body, a vertical rod disc buckle, and a lower connecting block; the vertical rod is connected to the bracket through the cooperation of the upper connecting cylinder and the bracket connecting block of the bracket, and the bracket connecting block is inserted into the upper connecting cylinder.

[0018] (1) The lifting rod of the bracket and the bracket connecting block are connected by a sliding groove and a protruding ridge to prevent the thread of the lifting rod from directly rubbing against the inner wall of the bracket connecting block, which greatly extends the service life of the bracket lifting adjustment structure.

[0019] (2) By improving the traditional cylindrical sleeve connection between the bracket, vertical rod and base to a polygonal sleeve connection structure, the problem of large swing amplitude and instability of the upper and lower overall connection caused by the easy deviation of the center of gravity between the connecting sleeves is overcome. This improves the overall stability and structural strength of the scaffolding and can meet the needs of large-span pouring construction. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1-8 As shown, this utility model discloses a support frame for large-span construction, including a bracket 1, a vertical rod 2, a base 3, a horizontal rod 4, and a pin 5, as well as pins 5 for fixing the vertical rod 2 and the horizontal rod 4. The bracket 1, vertical rod 2, and base 3 are connected sequentially from top to bottom in a polygonal sleeve structure. A vertical rod buckle 203 is provided in the middle area of ​​the vertical rod 2. The horizontal rod 4 is connected to the vertical rod 2 through the vertical rod buckle 203. The pin 5 passes through the mounting hole at the end of the horizontal rod and the mounting hole of the vertical rod buckle 203, connecting the vertical rod 2 and the horizontal rod 4. The specific form is shown in the attached figure. Figure 1 The enlarged view in the middle shows that the crossbar 4 is a conventional structure in this field, as shown in the attached figure. Figure 7 As shown.

[0032] like Figure 2 The diagram shows the structure of bracket 1. Bracket 1 includes a support plate 101, a lifting rod 102, an adjusting nut 103, and a bracket connecting block 104. The support plate 101 is rotatably mounted on the upper end of the lifting rod 102. The support plate 101 can be a U-shaped support plate, such as... Figure 2 As shown in (a), the U-shaped support plate is rotatably mounted at the top of the lifting rod; furthermore, the support plate 101 can be a circular flat support plate, such as... Figure 2 As shown in (b), the circular flat support plate is also rotatably mounted on the top of the lifting rod.

[0033] like Figure 3-4As shown, the lifting rod 102 consists of a fixing nut 1021, a sliding groove 1022, and a limiting block 1023. The upper end of the lifting rod 102 has a small-diameter area with a certain distance between it and the diameter of the middle region of the lifting rod 102. The center of the support plate 101 has a stepped hole that mates with the lifting rod. The smaller hole in the stepped hole mates with the small-diameter area at the upper end of the lifting rod 102, and the larger diameter hole in the stepped hole mates with the fixing nut 1021. The fixing nut 1021 limits the axial movement of the support plate 101 on the lifting rod 102 and allows the support plate 101 to rotate at the top of the lifting rod 102. Specifically, after the fixing nut 1021 is tightened into the threaded hole at the top of the support plate 101 (not shown in the attached figure), the support plate 101, the small-diameter shaft at the end of the lifting rod 102, and the fixing nut 1021 are in clearance fit, thereby realizing the axial positioning of the support plate 101 in the lifting rod 102 and the rotation around the axis of the lifting rod 102; the bracket connecting block 104 is a polygonal cylinder connected to the upper end of the vertical rod 2, with a circular hole at its center, and a protruding rib 1041 is provided on the inner wall of the circular hole along the axial direction.

[0034] The slide groove 1022 is axially arranged on the lifting rod 102. The slide groove 1022 and the protrusion 1041 provided on the inner wall of the bracket connecting block 104 slide together to limit the movement of the threaded rod during lifting and lowering, ensuring smoothness and structural stability during the thread lifting and lowering process. The limiting block 1023 is located at the lower end of the lifting rod 102 and is integral with the lifting rod 102. Its diameter is larger than the diameter of the central hole of the bracket connecting block 104. When assembling the bracket 1, first insert the bracket connecting block 104 from the upper end of the lifting rod 102, then screw the adjusting nut into the upper end of the lifting rod 102, and finally put the bracket plate 101 on the top of the lifting rod 102 and tighten the fixing nut 1021.

[0035] Due to the function of the protruding rib 1041, a certain gap can be maintained between the inner wall of the bracket connecting block 104 and the threaded area of ​​the lifting rod, so as to avoid the thread of the lifting rod 102 directly rubbing against the inner wall of the bracket connecting block 104 and extend the service life of the lifting adjustment structure of the bracket 1.

[0036] like Figure 5As shown, the vertical rod 2 includes: an upper connecting cylinder 201, a vertical rod body 202, a vertical rod disc buckle 203, and a lower connecting block 204. The vertical rod 2 is connected to the bracket 1 through the cooperation of the upper connecting cylinder 201 and the bracket connecting block 104 of the bracket 1. The bracket connecting block 104 can be inserted into the upper connecting cylinder 201. The bracket connecting block 104 and the upper connecting cylinder 201 are polygons with the same cross-sectional profile. Preferably, they can be regular hexagons. Through the fitting of the regular hexagonal bracket connecting block 104 and the regular hexagonal upper connecting cylinder 201, the connection gap between the vertical rod 2 and the bracket 1 can be made more uniform, so as to ensure the overall stability of the scaffolding and thus meet the needs of large-span pouring construction.

[0037] like Figure 6 As shown, the base 3 includes an upper connecting cylinder 301, a base rod 302, and a base plate 303. The base 3 is connected to the vertical rod 2 through the cooperation of the upper connecting cylinder 301 and the lower connecting block 204 of the vertical rod 2. The lower connecting block 204 can be inserted into the upper connecting cylinder 301. The lower connecting block 204 and the upper connecting cylinder 301 are regular polygons with the same cross-sectional profile. Preferably, they can be regular hexagons. Through the fitting of the regular hexagonal lower connecting block 204 and the regular hexagonal upper connecting cylinder 301, the connection gap between the base 3 and the vertical rod 2 can be made more uniform, so as to ensure the overall stability of the scaffolding and thus meet the needs of large-span pouring construction.

[0038] like Figure 8 As shown, those skilled in the art can, according to the needs of engineering construction, achieve support for concrete pouring work surfaces of different heights, areas, and spans through the cooperation of bracket 1, vertical rod 2, base 3, horizontal rod 4, and pin 5. This application will not elaborate further.

[0039] As can be seen from the accompanying drawings, in the embodiments of this utility model, the fixed connection and relative sliding of each component can be achieved by conventional methods of the prior art. The specific implementation method will not be further described in this utility model specification.

[0040] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
