Description

Technical Field

[0001] The utility model relates to the technical field of steel structure connection, in particular to a method for facilitating the rapid connection and positioning of steel structure nodes. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Its structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. There are many ways to connect the positioning nodes of steel structures and beams and columns. Bolt connection is a common metal structure connection method. This connection method is achieved by passing bolts through the connecting holes of beams and columns and tightening them with nuts.

[0003] The patent with publication number CN204627003U currently discloses a steel structure positioning node, including a supporting platform and a positioning template. A ball node placement groove is opened at the central position of the top of the positioning template, and a positioning adjustment mechanism is arranged between the supporting platform and the positioning template. Although the above device solves the problem of improving the positioning speed.

[0004] However, the above technical solution still has the following problems:

[0005] The structural stability is limited. The longitudinal and transverse beams or columns jointly bear the role of maintaining the structural stability. If the positioning nodes are only applicable to the longitudinal connection, there will be a lack of special positioning measures at the transverse connection, which may lead to insufficient accuracy and stability of the transverse connection, which will affect the overall stability of the entire structure and increase the risk of deformation or damage when the structure is subjected to stress. If the positioning nodes can only be used for longitudinal beam or column connections, but not for transverse beams or columns, it will have a negative impact on the stability, design flexibility, construction difficulty and structural performance of the structure. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a method for quickly and continuously positioning nodes of steel structures to at least solve one of the problems raised by the background technology, such as: allowing workers to complete the connection work of beams or columns in a short time, shortening the working time of a single connection point, thereby improving the overall construction speed.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a method for facilitating the rapid connection and positioning of nodes in a steel structure, comprising a first node assembly, a second node assembly, a pad and a plurality of external bolts, wherein the pad is located in the second node assembly, the second node assembly and the first node assembly are embedded and connected, and are fixedly connected by external bolts, and the second node assembly and one side of the first node assembly are fixedly connected to the surface of the steel structure by external bolts.

[0008] Furthermore, the first node assembly includes a fixing clamp and a connecting plate a, one end of the fixing clamp is fixedly connected to the center of the connecting plate a, a connecting hole a is opened on the surface of the connecting plate a, and an external bolt passes through the connecting hole a and is fixedly connected to the surface of the steel structure.

[0010] Furthermore, the cushion block is fitted and connected to the inner wall of the H-shaped fixing plate, and the outer side of one end of the cushion block is fitted and connected to the inner wall of the fixing clamp ring.

[0011] Furthermore, a connecting groove is provided on the outside of the fixing clamp, a circular hole is provided at the bottom of the connecting groove, a threaded hole aligned with the circular hole is provided on the outside of the cushion block, and an external bolt passes through the circular hole and is threadedly connected with the threaded hole.

[0012] Furthermore, the bottom of the connecting groove and the bottom of the bolt cap of the external bolt are arranged horizontally.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model enables fast connection of the positioning nodes through positioning, and is suitable for connection on the surfaces of various beams or columns.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figures 1 to 4 As shown, a method for quickly and continuously positioning nodes of a steel structure includes a first node component 1, a second node component 2, a cushion block 3 and a plurality of external bolts, wherein the cushion block 3 is located in the second node component 2, the second node component 2 and the first node component 1 are embedded and connected, and are fixedly connected by external bolts, and the second node component 2 and one side of the first node component 1 and the surface of the steel structure are fixedly connected by external bolts.

[0022] like Figure 1 As shown, a kind of node in the utility model that facilitates the rapid connection of steel structure positioning nodes is similar to the existing steel structure positioning node structure, such as the steel structure positioning node disclosed in the patent with publication number CN204627003U. The main improvement of the utility model is to ensure the continuity of the structure, so that the whole structure can be evenly stressed in the horizontal and vertical directions, and effectively avoid the structural failure problem caused by loose connection, such as Figures 1 to 4 As shown, the utility model is a method for facilitating the rapid connection of positioning nodes of steel structures. When in use, the embedded connection method of the first node component 1 and the second node component 2 is adopted, and the fixing of the external bolts is cooperated to make the node connection fast and simple. The pad 3 ensures the stability and tightness of the node connection. The pad 3 is a sealing compensation part, which is mainly used to fill the gap between structural members. In the connection of the positioning node, the pad 3 is used to ensure the tight connection between the first node component 1 and the second node component 2, thereby ensuring the stability and bearing capacity of the connection. The positioning node component is fixedly connected to the surface of the steel structure by external bolts, which further enhances the overall stability of the node. The external bolts accurately fix different positioning node components at predetermined positions of beams or columns, thereby improving the adaptability of the positioning component to the steel structure.

[0023] like Figure 3 As shown, the first node assembly 1 includes a fixing clamp 4 and a connecting plate a5, one end of the fixing clamp 4 is fixedly connected to the center of the connecting plate a5, a connecting hole a501 is opened on the surface of the connecting plate a5, and an external bolt passes through the connecting hole a501 and is fixedly connected to the surface of the steel structure.

[0024] Specifically, a connection hole a501 is opened on the surface of the connecting plate a5 through this setting, which is for realizing connection with an external bolt. When the external bolt passes through the connection hole a501 and is fixedly connected to the surface of the steel structure, the first node component 1 is firmly fixed at a predetermined position of the steel structure. This connection method is simple and fast, and has high connection strength and can withstand large external forces.

[0025] like Figure 3 to Figure 4 As shown, the second node assembly 2 includes an H-shaped fixing plate 6 and a connecting plate b7. One end of the H-shaped fixing plate 6 is fixedly connected to the center of the connecting plate b7, and the other end is inserted and connected to the fixing clamp 4. The outer side of the H-shaped fixing plate 6 is fit-connected to the inner wall of the fixing clamp 4. The length of the H-shaped fixing plate 6 is equal to the height of the fixing clamp 4. A connecting hole b701 is opened on the surface of the connecting plate b7. The external bolt passes through the connecting hole b701 and is fixedly connected to the surface of the steel structure.

[0026] Specifically, the H-shaped fixing plate 6 is provided with good structural rigidity and stability and is capable of withstanding forces from different directions. One end of the H-shaped fixing plate 6 is fixedly connected to the center of the connecting plate b7 to ensure the integrity of the second node assembly 2; the other end is inserted and connected to the fixing clamp 4 to ensure a tight connection between the second node assembly 2 and the first node assembly 1, thereby improving the connection stability between the node assemblies and enabling the entire positioning node to maintain its stability and integrity when subjected to external forces; the connecting hole b701 opened on the surface of the connecting plate b7 provides a connection channel for external bolts, so that the second node assembly 2 can be firmly fixed on the surface of the steel structure.

[0027] like Figure 2 As shown, the cushion block 3 is fitted and connected to the inner wall of the H-shaped fixing plate 6 , and the outer side of one end of the cushion block 3 is fitted and connected to the inner wall of the fixing clamp 4 .

[0028] Specifically, the close connection between the pad block 3 and the inner wall of the H-shaped fixing plate 6 is set to ensure the tightness and stability between the two. The high degree of fit between the shape of the pad block 3 and the inner wall of the H-shaped fixing plate 6 further improves the stability and bearing capacity of the entire node assembly. By ensuring the close fit between the pad block 3 and the fixing clamp 4, the connection strength and stability of the positioning node can be further improved.

[0029] like Figures 2 to 3 As shown, a connecting groove 401 is provided on the outside of the fixing clamp 4, a circular hole 402 is provided at the bottom of the connecting groove 401, a threaded hole 301 is provided on the outside of the cushion block 3 and is aligned with the circular hole 402, and an external bolt passes through the circular hole 402 and is threadedly connected with the threaded hole 301.

[0030] Specifically, the connection groove 401 is provided with an interface for connecting with external components, and the circular hole 402 at the bottom of the connection groove 401 is used in conjunction with an external bolt, so that the external bolt can smoothly pass through the two holes, and the cushion block 3 and the fixing clamp 4 are firmly connected together through a threaded connection, and the threaded connection between the circular hole 402 and the threaded hole 301 through which the external bolt passes, achieves a tight fixation between the cushion block 3 and the fixing clamp 4.

[0031] like Figure 3 As shown, the bottom of the connecting groove 401 and the bottom of the bolt cap of the external bolt are arranged horizontally.

[0032] Specifically, this horizontal setting ensures that there is a smooth and tight contact surface between the connecting groove 401 and the bolt cap of the external bolt. This contact method helps to disperse the force exerted on the bolt and prevent loosening or deformation caused by uneven force. Therefore, the node assembly can maintain higher stability when subjected to external force.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
