Description

Technical Field

[0001] This utility model relates to a post-stiffening structure for a steel structure slide joint. Background Technology

[0002] When installing soundproof modular walls in steel-structured houses using a method of inserting them one by one from the top of the house and stacking them down along a sliding track, the track, serving as the construction and installation channel, must not have any obstructions such as stiffening plates. However, many houses have cantilevered eaves and column corbels, requiring rigid connections with the columns. This necessitates the installation of stiffening plates that penetrate the track and are tightly fitted to the column's outer flange to ensure the joint's rigidity. If stiffening plates are installed at the joint in advance, it will inevitably affect the use of the track, making it impossible to install the modular walls smoothly; if stiffening plates are not installed, the structural load-bearing requirements cannot be met. Conventional post-stiffening methods present numerous safety hazards after installing the modular walls, are inconvenient for welding construction, or involve complex construction processes, significantly impacting project schedule and cost, and are also difficult to disassemble after welding. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings in the existing technology and provide a reasonably designed steel structure chute joint stiffening structure. This avoids the chute becoming unusable due to the pre-setting of stiffening crossbars, and also avoids structural damage due to the lack of joint stiffening measures. At the same time, the construction process is simple, reliable, and has little adverse impact on the original structure.

[0004] The technical solution adopted by this utility model to solve the above problems is: a post-stiffening structure for a steel structure sliding groove node, including a steel column, a steel sliding groove, a column cantilever beam, and a sound insulation module wall; the steel sliding groove is fixed on the steel column, the column cantilever beam is fixed on the steel sliding groove, and the sound insulation module wall is inserted into the steel sliding groove; the characteristic is that it also includes a post-stiffening component, which is set at the node connecting the column cantilever beam and the steel sliding groove, and includes bolts, nuts, and sleeves; a steel sliding groove hole is opened on the steel sliding groove, and a steel column hole is opened on the steel column; the sleeve is installed on the sound insulation module wall, and the sleeve is located in the steel sliding groove, with both ends of the sleeve pressed against the steel sliding groove; the bolt passes through the steel sliding groove hole, the sleeve, and the steel column hole in sequence and is then tightened with a nut.

[0005] The steel column of this utility model has the aforementioned steel column hole on its outer flange.

[0006] The nut described in this utility model is a double nut.

[0007] The column cantilever beam described in this utility model is a solid web or truss steel beam.

[0008] The sound insulation module of this utility model has a wall hole, and the sleeve is installed in the wall hole.

[0009] The steel column described in this utility model is a solid web H-shaped steel column, a channel steel column, or a lattice-type T-shaped composite section steel column.

[0010] The steel chute described in this utility model is a T-shaped steel, channel steel, or H-shaped steel.

[0011] The steel column described in this utility model is fixed with a stiffening plate.

[0012] Compared with existing technologies, this utility model has the following advantages and effects: 1. The stiffening component can withstand various loads such as tension, compression, shear, and torsion, providing a certain degree of node stiffness. 2. The stiffening component can be installed after the chute has been used, which avoids the situation where the chute becomes unusable due to the pre-installation of stiffening crossbars, and also avoids the situation where the structure is damaged due to the lack of node stiffening measures.

[0014] Figure 2 This is a partial structural schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0016] This utility model embodiment includes a steel column 1, a steel sliding groove 2, a column cantilever beam 3, a soundproof modular wall 4, and a post-stiffening component 5.

[0017] The steel column 1 can be a solid-web H-shaped steel column, a channel steel column, or a lattice-type T-shaped composite section steel column, etc. The steel groove 2 is welded and fixed to the steel column 1; the steel groove 2 can be T-shaped steel, channel steel, H-shaped steel, etc. The column cantilever beam 3 is welded and fixed to the steel groove 2; the column cantilever beam 3 can be various types of solid-web or truss steel beams, or it can be a corbel or other structure requiring rigid connection. The soundproof modular wall 4 is inserted into the steel groove 2; the soundproof modular wall 4 is a vertically installed prefabricated modular wall.

[0018] The post-stiffening assembly 5 is installed at the node connecting the column cantilever beam 3 and the steel slide 2, and includes bolts 6, nuts 7 and sleeves 8. The steel slide 2 has a steel slide hole 21, the sound insulation module wall 4 has a wall hole 41, and the outer flange of the steel column 1 has a steel column hole 11.

[0019] The sleeve 8 is a ring sleeve, and the sleeve 8 is installed in the wall hole 41. The size of the sleeve 8 should take into account the stiffening requirements and allow for a certain margin for installation deviation. The sleeve 8 is located in the steel groove 2, and the length of the sleeve 8 should be close to the width of the steel groove 2 to ensure that the two ends of the sleeve 8 can be tightly pressed against the steel groove 2 after installation.

[0020] Bolt 6 passes sequentially through the steel groove hole 21, sleeve 8, and steel column hole 11, and is then tightened with nut 7. Bolt 6 is a common bolt or a high-strength bolt with tensioning or tightening function. Bolt 6 can also be replaced by components with tensioning function such as steel strand or round steel. Nut 7 is a double nut.

[0021] A stiffening plate 9 is fixed on the steel column 1. Whether the stiffening plate 9 is needed and its size are determined by the design unit. If needed, it will be cut together with the steel column 1.

[0022] The working principle of this utility model is as follows:

[0023] The design unit determines the required quantity and location of the post-stiffening components 5 based on the stress requirements, and provides design drawings for hole positioning and the specifications of the post-stiffening components 5. The steel structure manufacturer pre-positions and drills holes during material cutting at the factory according to the design drawings; the sound insulation manufacturer pre-drills holes in the sound insulation module wall 4 at the designated locations according to the design drawings, a step that can also be performed on-site. When installing the sound insulation module wall 4 on-site, the sleeve 8 is inserted into the wall hole 41 and its outward protrusion adjusted. After being inserted into the steel groove 2 along with the sound insulation module wall 4 and installed in place, bolts 6 are passed through the steel groove hole 21, sleeve 8, and steel column hole 11, and then tightened with nuts 7. Bolts 6, nuts 7, and sleeves 8 together form a stiffening system, which can withstand various types of forces such as tension, compression, shear, and torsion, depending on the type of bolts 6 selected. When it is necessary to disassemble and inspect the module wall, the wall can be easily removed by unscrewing and taking out the bolts 6.

[0024] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components.
