Description

Technical Field

[0001] This utility model relates to the field of building structure reinforcement components, and in particular to a reinforcement device for preventing horizontal displacement of an arc-shaped cantilevered space frame. Background Technology

[0002] As a special form of building structure, the curved cantilever space frame has advantages such as aesthetic appeal and high space utilization, but it also faces some technical challenges. Due to its unique shape and stress characteristics, the curved cantilever space frame is prone to horizontal displacement when subjected to external factors such as wind, temperature changes, and construction loads, thus affecting the stability and safety of the structure. To prevent horizontal displacement of the curved cantilever space frame, various reinforcement methods and technologies are currently used in engineering practice, including but not limited to: adding prestressed cables: using high-strength cables to reinforce the curved cantilever space frame, improving the overall load-bearing capacity and stability of the structure through prestressing. This method has advantages such as simple construction and significant effects, but requires precise calculation and control of the prestress of the cables; using new materials: with the continuous development of materials science, more and more new materials are being applied to the reinforcement of building structures. For example, carbon fiber composites and high-strength steel have excellent mechanical properties and durability, and can be used to make reinforcement devices or replace damaged components, but new materials are expensive, which is not conducive to widespread adoption. Therefore, it is necessary to develop a reinforcement device to prevent horizontal displacement of the curved cantilever space frame. Utility Model Content

[0003] The purpose of this invention is to provide a reinforcement device for preventing horizontal displacement of an arc-shaped cantilevered space frame, thereby solving the technical problems mentioned in the background section, improving construction efficiency and quality, reducing project costs, and meeting the stability and safety requirements of the arc-shaped cantilevered space frame structure.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses a reinforcement device for preventing horizontal displacement of an arc-shaped cantilevered space frame, comprising a horizontal base plate. The bottom of the horizontal base plate is fixedly connected to the upper surface of a concrete column, and two first vertical plates are symmetrically fixedly arranged at both ends of the bottom of the base plate for fixed connection to the two sides of the concrete column. The upper part of the horizontal base plate is fixedly connected to the bottom of a ball joint support, and two second vertical plates are symmetrically fixedly arranged at both ends of the upper part for fixed connection to the side wall of the ball joint support. The ends of two adjacent horizontal base plates are fixedly connected by a connecting rod.

[0006] Furthermore, the bottom of the horizontal base plate and the opposite sides of the two first vertical plates are welded to the pre-embedded steel bars on the concrete column; the upper part of the horizontal base plate and the opposite sides of the two second vertical plates are welded to the ball joint support.

[0007] Furthermore, a first diagonal brace is provided between each of the first upright plates and the connecting rod at the corresponding end, and a second diagonal brace is provided between each of the second upright plates and the connecting rod at the corresponding end.

[0008] Furthermore, the lower part of the connecting rod is symmetrically provided with two sets of first connecting ears, and the part of the first upright plate near the lower end is provided with a second connecting ear. The two ends of the first diagonal brace are respectively connected to the corresponding first connecting ear and second connecting ear.

[0009] Furthermore, two sets of third connecting ears are symmetrically arranged on the upper part of the connecting rod, and a fourth connecting ear is arranged near the lower end of the second upright plate. The two ends of the second diagonal brace are respectively connected to the corresponding third connecting ear and fourth connecting ear.

[0010] Furthermore, the first upright plate is fixedly connected to the concrete column by a plurality of evenly arranged anchoring components.

[0011] Furthermore, each of the anchoring components includes a connecting seat, one end of which is located on the outside of the first upright plate and is fixedly connected to the first upright plate by welding, and the other end of which passes through the first upright plate and is fixedly provided with an anchoring cylinder implanted inside the concrete column.

[0012] Furthermore, the connecting seat has a threaded hole in the middle and a feed screw threadedly connected to it. A transmission head is fixedly installed at one end of the feed screw outside the connecting seat, and multiple frustum-shaped extrusion heads are evenly spaced and fixedly installed at the other end of the feed screw inside the anchoring cylinder. The anchoring cylinder has multiple movable seats evenly arranged circumferentially at positions corresponding to each extrusion head. The inner circumferential wall of each movable seat is set as a conical surface structure that matches the outer circumferential wall contour of the extrusion head. The outer middle of each movable seat is fixedly connected to one end of a spring arranged radially along the anchoring cylinder. The other end of the spring is fixedly connected to the inner circumferential wall of the anchoring cylinder. The part of the movable seat inside the spring is fixedly connected to one end of an anchor. The anchor slides in fit with a through hole opened on the circumferential wall of the anchoring cylinder, and its other end is set as a sharp structure.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] This invention effectively improves the horizontal connection strength of the curved cantilevered space frame after installation by setting a clamping structure consisting of two sets of vertical plates at the bottom of the spherical hinge support used for installing the curved cantilevered space frame and on the concrete column. This reduces displacement. Furthermore, by fixing two adjacent horizontal base plates together with connecting rods, the two sets of clamping structures are firmly connected, forming an integrated force-bearing system, further limiting the horizontal displacement of the curved cantilevered space frame. By adding extra support and connection structures, this invention improves the overall rigidity and stability of the curved cantilevered space frame, ensuring its safety and reliability under various working conditions and effectively preventing horizontal displacement that may occur when the curved cantilevered space frame is subjected to external factors such as wind, temperature changes, and construction loads.

[0022] Example 1

[0023] like Figures 1-2As shown, a reinforcement device for preventing horizontal displacement of an arc-shaped cantilevered space frame includes a horizontal base plate 1. The bottom of the horizontal base plate 1 is fixedly connected to the upper surface of a concrete column 2, and two first vertical plates 3 are symmetrically fixedly installed at both ends of the bottom of the base plate 1 for fixed connection to the two sides of the concrete column 2. The upper part of the horizontal base plate 1 is fixedly connected to the bottom of a ball joint support 4 for mounting the arc-shaped cantilevered space frame, and two second vertical plates 5 are symmetrically fixedly installed at both ends of the upper part of the base plate 1 for fixed connection to the side walls of the ball joint support 4. The ends of two adjacent horizontal base plates 1 are fixedly connected by a connecting rod 6.

[0024] In this embodiment, the bottom of the horizontal base plate 1 and the opposite sides of the two first vertical plates 3 are welded to the pre-embedded steel bars on the concrete column 2; the upper part of the horizontal base plate 1 and the opposite sides of the two second vertical plates 3 are welded to the ball joint support 4.

[0025] This invention effectively improves the horizontal connection strength of the curved cantilevered space frame after installation by setting a clamping structure consisting of two sets of vertical plates at the bottom of the ball joint support used for installing the curved cantilevered space frame and on the concrete column. This reduces displacement. In addition, by fixing two adjacent horizontal base plates together with connecting rods, the two sets of clamping structures are firmly connected to form an overall force-bearing system, further limiting the horizontal displacement of the curved cantilevered space frame.

[0026] Example 2

[0027] like Figures 3-5 As shown, in this embodiment, without changing the other structures of Embodiment 1, a first diagonal brace 7 is provided between each of the first upright plates 3 and the corresponding end of the connecting rod 6, and a second diagonal brace 8 is provided between each of the second upright plates 5 and the corresponding end of the connecting rod 6.

[0028] Specifically, the lower part of the connecting rod 6 is symmetrically provided with two sets of first connecting ears 9, and the lower part of the first upright plate 3 is provided with a second connecting ear 10. The two ends of the first diagonal brace 7 are respectively connected to the corresponding first connecting ear 9 and second connecting ear 10. The upper part of the connecting rod 6 is symmetrically provided with two sets of third connecting ears 11, and the lower part of the second upright plate 5 is provided with a fourth connecting ear 12. The two ends of the second diagonal brace 8 are respectively connected to the corresponding third connecting ear 11 and fourth connecting ear 12.

[0029] This embodiment sets diagonal bracing structures on the connecting rod and the first and second vertical plates at both ends, thereby forming a triangular support structure between the clamping plate structure and the connecting rod that is not easily deformed, further ensuring the reinforcement strength of the space frame installation part and preventing horizontal displacement.

[0030] In addition, in this embodiment, the first upright plate 3 is fixedly connected to the concrete column 2 by a plurality of evenly arranged anchoring components, which replaces the welding connection method in Embodiment 1.

[0031] Each of the anchoring components includes a connecting seat 13. One end of the connecting seat 13 is located outside the first upright plate 3 and is fixedly connected to the first upright plate 3 by welding. The other end of the connecting seat 13 passes through the first upright plate 3 and is fixedly provided with an anchoring cylinder 14 implanted inside the concrete column 2.

[0032] The connecting seat 13 has a threaded hole in the middle and a feed screw 15 threadedly connected to it is installed. A transmission head 16 is fixedly installed at one end of the feed screw 15 outside the connecting seat 13 for use with tools such as wrenches. Multiple frustum-shaped extrusion heads 17 are evenly spaced and fixedly installed at one end of the feed screw 15 inside the anchoring cylinder 14. Multiple movable seats 18 are evenly arranged circumferentially at positions corresponding to each extrusion head 17 on the anchoring cylinder 14. The inner circumferential wall of each movable seat 18 is configured as a conical surface structure that matches the outer circumferential wall contour of the extrusion head 17. The outer middle of each movable seat 18 is fixedly connected to one end of a spring 19 arranged radially along the anchoring cylinder 14. The other end of the spring 19 is fixedly connected to the inner peripheral wall of the anchoring cylinder 14. The part of the movable seat 18 located inside the spring 19 is fixedly connected to one end of an anchor 20. The anchor 20 slides in a through hole opened on the peripheral wall of the anchoring cylinder 14 and its other end is set as a sharp structure.

[0033] During construction, the anchoring cylinder is first inserted through the through hole in the second vertical plate and into the concrete column. The outer edge of the connecting seat is then welded to the outer side of the second vertical plate. Next, the transmission head is rotated with a wrench to move the feed screw towards the inner end of the anchoring cylinder. As the transmission heads on the feed screw move together, they exert a squeezing effect on the movable seats on their outer sides, causing the movable seats to move the anchors towards the outer side of the anchoring cylinder. This allows the sharp parts of the anchors to penetrate the concrete column, further improving the connection strength between the second vertical plate and the concrete column.

[0034] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
