Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and in particular to a circular adjustable limit bracing structure and a floor deck bottom support structure. Background Technology

[0002] In steel pipe scaffolding support systems, adjustable supports are a key component, primarily functioning to transfer loads to the support frame. A typical adjustable support usually consists of a U-shaped top plate and an adjustment mechanism, such as a combination of a threaded screw and an adjusting nut. This adjustment mechanism allows the adjustable support to be height-adjusted within a specific range.

[0003] Currently, prefabricated floor slabs with non-removable steel truss structures are widely used due to their significant advantages, such as light weight, large span without support, and minimal occupation of tower crane space. Their bottom support structure employs wide, multi-rectangular tube composite joists arranged perpendicular to the steel truss direction, representing a novel bottom support structure. However, traditional adjustable supports have limitations: their U-shaped top plates open upwards with relatively short openings, making them unsuitable for the dimensions of wide joists. Furthermore, traditional adjustable supports can only be arranged in a single direction, resulting in low installation efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a circular limit adjustable support structure and a floor deck bottom support structure, which solves the problems of mismatch with the size of wide keel and low installation efficiency of traditional adjustable supports.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A circular adjustable support structure includes a horizontally arranged circular top plate with a circular hole at its center. A vertically arranged threaded rod passes through the hole, and an adjusting nut is threaded onto the rod near the lower side of the top plate. An annular steel plate is coaxially arranged on the lower side of the top plate, with its outer diameter equal to that of the top plate and one end face fitting against the lower side surface of the top plate. Multiple stiffening ribs are distributed around the lower side of the top plate, each stiffening rib being a right-angled trapezoid with its right-angled side fixedly connected to the lower side of the top plate. One bottom edge is fixedly connected to the inner wall of the annular steel plate, and the other bottom edge is fixedly connected to the threaded rod.

[0007] Based on the aforementioned circular adjustable support structure, this utility model also provides a floor deck bottom support structure, including the aforementioned circular adjustable support structure, which is installed on a support frame; it also includes multiple steel keels connected in sequence, with a circular adjustable support structure provided at the connection point of adjacent steel keels; wherein, each end of the steel keel is provided with a mortise and tenon and a mortise head, and the mortise head includes two parallel and oppositely arranged first rectangular tubes, and the distance between the two first rectangular tubes is matched with the diameter of the threaded rod, so that the rod body near the upper side of the top plate can extend into the two first rectangular tubes. Between the rectangular tubes; the mortise and tenon joint includes two parallel and oppositely arranged second rectangular tubes, and multiple connecting holes are distributed along the length direction of the first and second rectangular tubes; the length direction of the first and second rectangular tubes is consistent with the length direction of the steel keel. When multiple steel keels are connected end to end in sequence, the first rectangular tube can be inserted into the gap between the two second rectangular tubes, and the plate surface of the first rectangular tube is in contact with the second rectangular tube. At least one connecting hole on the first rectangular tube is opposite to the connecting hole on the second rectangular tube. A screw is inserted in the two opposite connecting holes, and at least one side of the screw abuts against the threaded rod.

[0008] As an optimization, the steel keel is an extension of the second rectangular tube, and the first rectangular tube is fixed between the two second rectangular tubes to form the mortise and tenon head. A connecting plate is also fixed between the two second rectangular tubes so that the ends of the two second rectangular tubes away from the mortise and tenon head form the mortise and tenon eye.

[0009] As an optimization, the connecting hole is a strip-shaped hole, and its length direction is consistent with the length direction of the steel keel.

[0010] Compared with the prior art, this application has the following advantages:

[0011] This utility model,

[0012] 1. Compared with the traditional adjustable U-shaped roof panel, the design of the circular roof panel increases its adaptability to wide multi-rectangular tube combined keel, can be installed in any direction, and improves installation efficiency;

[0013] 2. By extending a certain length of threaded rod from the top plate and cooperating with the threaded rod of the keel, a simple limit is achieved to prevent the keel from sliding and falling after installation, thus increasing the safety of the support system.

[0014] 3. The reasonable arrangement of trapezoidal stiffening ribs effectively enhances the load-bearing capacity of the adjustable support, ensuring the safety and reliability of the structure and extending its service life when subjected to large loads. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] For specific implementation: see [link / reference] Figures 1-2 ,

[0020] An embodiment of a circular adjustable support structure includes a horizontally positioned circular top plate 1 with a circular hole at its center. A vertically positioned threaded rod 2 passes through the hole and extends upwards a certain length after passing through the hole. In this embodiment, an adjusting nut 3 is threaded onto the threaded rod 2 near the lower side of the top plate 1, allowing for convenient adjustment of the support height. A ring-shaped steel plate 4 is coaxially positioned on the lower side of the top plate 1, with its outer diameter equal to the diameter of the top plate 1 and one end face fitting against the lower surface of the top plate 1. Six stiffening ribs 5 are distributed around the lower side of the top plate 1, each stiffening rib being a right-angled trapezoid with its right-angled side fixedly connected to the lower side of the top plate 1. One bottom edge is fixedly connected to the inner wall of the ring-shaped steel plate 4, and the other bottom edge is fixedly connected to the threaded rod 2. The ring-shaped steel plate and the stiffening ribs 5 significantly enhance the load-bearing capacity of the top support.

[0021] Based on the above-mentioned support structure, this utility model also provides a floor deck bottom support structure, including the aforementioned circular adjustable support structure, which is installed on a support frame; it also includes multiple steel keels 6 connected in sequence, with a circular adjustable support structure provided at the connection of adjacent steel keels 6; wherein, each end of the steel keel 6 is provided with a mortise and tenon eye and a mortise and tenon head, the mortise and tenon head including two parallel and oppositely arranged first rectangular tubes 7, and the distance between the two first rectangular tubes 7 is matched with the diameter of the threaded rod 2, so that the rod body of the threaded rod 2 near the upper side of the top plate 1 can extend into the space between the two first rectangular tubes 7; the mortise and tenon eye includes two parallel and oppositely arranged second rectangular tubes 8, and at the first Multiple connecting holes are distributed along the length direction of the rectangular tube 7 and the second rectangular tube 8. The length direction of the first rectangular tube 7 and the second rectangular tube 8 is consistent with the length direction of the steel keel 6. When multiple steel keels 6 are connected end to end in sequence, the first rectangular tube 7 can be inserted into the gap between the two second rectangular tubes 8, and the plate surface of the first rectangular tube 7 is in contact with the second rectangular tube 8. At least one connecting hole on the first rectangular tube 7 is opposite to the connecting hole on the second rectangular tube 8. A screw 9 is inserted in the two opposite connecting holes, and at least one side of the screw 9 abuts against the threaded rod 2, thereby restricting the displacement of the steel keel 6. The specific positions of the threaded rod 2 and the screw 9 are determined according to the need to restrict the displacement direction of the steel keel 6 and the number of screws 9.

[0022] The steel keel 6 is an extension of the second rectangular tube 8. The first rectangular tube 7 is fixed between the two second rectangular tubes 8 to form the mortise and tenon head. A connecting plate is also fixed between the two second rectangular tubes 8 so that the ends of the two second rectangular tubes 8 away from the mortise and tenon head form a mortise and tenon eye.

[0023] Thus, the steel keel 6, with its mortise and tenon structure, is easier to install. Multiple connection holes are provided on the first rectangular tube 7 and the second rectangular tube 8, allowing for adjustment of the spacing between adjacent steel keels 6 as needed, thereby adjusting the length of the support structure and expanding its applicability. Simultaneously, the screws 9 passing through the connection holes provide a good locking function, preventing the steel keels 6 from separating. Furthermore, the screws 9, located on one side of the threaded rod 2, act as a limit, preventing the steel keel 6 from slipping off the top plate 1 when it moves, thus improving safety.

[0024] The support frame includes a steel pipe scaffold, and the adjustable support structure is provided on the uprights of the steel pipe scaffold. In use, multiple steel keels 6 are connected to form a support beam. The support beam overlaps on the adjustable support top plate 1, so that the steel keels 6 near both ends of the support beam form a cantilever structure. The floor decking presses on the support beam on both sides along the width direction, thereby completing the support of the floor decking.

[0025] In summary, this utility model,

[0026] 1. Compared with the traditional adjustable U-shaped roof panel, the design of the circular roof panel increases its adaptability to wide multi-rectangular tube combined keel, can be installed in any direction, and improves installation efficiency;

[0027] 2. By extending a certain length of threaded rod from the top plate and cooperating with the threaded rod of the keel, a simple limit is achieved to prevent the keel from sliding and falling after installation, thus increasing the safety of the support system.
