Description

Technical Field

[0001] The utility model relates to the technical field of steel structure connection, in particular to a novel steel structure fastening device. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates. At present, in the connection of prefabricated steel structures, bolts are usually used to connect the components. Generally, the steel structure connectors are sleeve-type, which are directly inserted from one end of the support column, moved to the connection position and tightened, and then each support beam is connected to the steel structure connector through a separate connection plate or connection block, so as to achieve the installation and fixation between the steel beam and the support column.

[0003] For example, a steel structure connection node disclosed in the publication number CN209211623U includes a node cylinder and a plurality of support beams arranged on the node cylinder, a connection sleeve is sleeved on the node cylinder, and the support beam is detachably connected to the connection sleeve through a plug-in assembly, and the plug-in assembly includes a plurality of embedded blocks arranged on the side wall of the connection sleeve, a connection plate arranged at one end of the support beam, an embedded groove provided on the connection plate for the embedded blocks to be embedded, and a support boss arranged on the lower side of the connection sleeve and used to abut against the lower side of the connection plate, and two adjacent connection plates are connected by a fixing assembly. When the support beam bears load, the force will be transmitted to the embedded block through the inner wall of the embedded groove, which can bear load well and evenly transmit the force to the node cylinder, without the need for load bearing through bolts, reducing the possibility of fracture of the connection when bearing load, and improving the structural strength.

[0004] However, the steel structure connection method in the above technology still has the following problems:

[0005] During actual installation, it is necessary to put the sleeve on the supporting column in advance. If the sleeve needs to be added or replaced during the installation process and later maintenance, it cannot be carried out smoothly, which causes great inconvenience to the later maintenance of the steel structure. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a novel steel structure fastening device, such as: designing a sleeve as a module that can be spliced ​​and disassembled, so as to facilitate the subsequent disassembly and installation of the sleeve directly on the outside of the support column, thereby improving the installation and maintenance efficiency of the steel structure.

[0008] Furthermore, the splicing assembly includes a triangular plate and two U-shaped plates. A connecting groove matching the connecting column is provided on one side of the triangular plate close to the connecting column. The outer walls of the triangular plate on both sides away from the connecting column are respectively fixedly connected to the two U-shaped plates. Two bolt holes are provided on both sides of the two adjacent triangular plates that abut each other, and the two adjacent bolt holes are fixedly connected by bolts.

[0009] Furthermore, the opening of the U-shaped plate faces upward, one end of the support beam of the same group is slidably connected to the inner wall of the U-shaped plate, and the U-shaped plate and the support beam are fixedly connected by a plurality of bolts.

[0010] Furthermore, the outer wall of the connecting column is provided with two symmetrically arranged positioning holes, the inner walls of the two positioning holes are both plugged with positioning blocks, and the sides of the two positioning blocks away from the positioning holes are respectively fixedly connected to the inner walls of the two connecting grooves.

[0011] Furthermore, a connecting hole is provided on the side of the connecting column close to the base, a limiting hole is provided on the side of the connecting hole away from the base, a connecting block is fixedly connected to the side of the base close to the connecting column and the side of the connecting column away from the base, and the two connecting blocks are fixedly connected to the limiting blocks on the sides away from the base, the limiting blocks are plugged into adjacent limiting holes, and the connecting blocks are slidably connected to the inner walls of the adjacent connecting holes.

[0012] Furthermore, the limiting block and the limiting hole are asymmetrically designed.

[0013] Furthermore, a plug hole is penetrated through one side of the connection block, and a plug pin is slidably connected to the inner wall of the plug hole, and both ends of the plug pin penetrate the outer wall of the adjacent connection column and are slidably connected thereto.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] This novel steel structure fastening device uses two symmetrically arranged splicing components to sleeve and connect the connecting columns, and installs the supporting beam on the splicing components. Therefore, when the supporting beam needs to be maintained or replaced, the splicing components can be directly replaced on the outside of the connecting column, which makes the operation more convenient and quick, and improves the working efficiency.

[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] See also Figure 1 - Figure 3 A new type of steel structure fastening device includes a base 1 installed on the ground, a connecting column 2 is connected to the side of the base 1 away from the bottom surface, the outer wall of the connecting column 2 is connected to two symmetrically arranged splicing components 3, the two splicing components 3 are sleeved on the outer wall of the connecting column 2, and the two splicing components 3 are connected to multiple support beams 4 on the side away from the connecting column 2.

[0022] like Figure 1 - Figure 3 As shown, the new steel structure fastening device in the utility model is similar to the existing new steel structure fastening device structure, such as a steel structure connection node disclosed in the patent with publication number CN209211623U. The main improvement of the utility model is that the user can more conveniently install the connection device on the support column, thereby improving the installation efficiency. Figures 1 to 3 As shown, when the new steel structure fastening device in the utility model is used, the base 1 is first installed on the bottom surface, and then the connecting column 2 is installed on the base 1 to complete the vertical rod positioning of the connecting column 2, and then two splicing components 3 are used to connect each other and are sleeved on the outer wall of the connecting column 2 and fixed. At this time, multiple support beams 4 can be installed on the two splicing components 3 to complete the erection of the entire steel structure.

[0023] like Figure 1 and Figure 2As shown, the splicing assembly 3 includes a triangular plate 31 and two U-shaped plates 32. A connecting groove 301 matching the connecting column 2 is provided on one side of the triangular plate 31 close to the connecting column 2. The outer walls of the two sides of the triangular plate 31 away from the connecting column 2 are respectively fixedly connected to the two U-shaped plates 32. Two bolt holes 302 are provided on both sides of the two adjacent triangular plates 31. The two adjacent bolt holes 302 are fixedly connected by bolts. When installing the splicing assembly 3, the two triangular plates 31 are respectively put on both sides of the connecting column 2, the connecting groove 301 is attached to the outer wall of the connecting column 2, and the positions of the bolt holes 302 on the two triangular plates 31 are aligned with each other. Then, the two triangular plates 31 are fixed through the bolt holes 302 with bolts. After the fixed installation is completed, the multiple support beams 4 are respectively fixed to the U-shaped plates 32 on the two triangular plates 31 to complete the installation and connection of the steel structure.

[0024] like Figure 1 and Figure 2 As shown, the opening of the U-shaped plate 32 faces upward, one end of the same group of support beams 4 is slidably connected to the inner wall of the U-shaped plate 32, and the U-shaped plate 32 and the support beam 4 are fixedly connected by multiple bolts. The opening of the U-shaped plate 32 is designed to face upward, so that when the support beam 4 is installed, one end of the support beam 4 can be placed on the U-shaped plate 32, which is more convenient for subsequent fixing with bolts. Bolts are used on the U-shaped plate 32 and the support beam 4 to be staggered and penetrated to improve the connection firmness between the U-shaped plate 32 and the support beam 4.

[0025] like Figure 2 As shown, the outer wall of the connecting column 2 is provided with two symmetrically arranged positioning holes 201, and the inner walls of the two positioning holes 201 are both plugged with positioning blocks 21, and the sides of the two positioning blocks 21 away from the positioning holes 201 are respectively fixedly connected to the inner walls of the two connecting grooves 301. When the two triangular plates 31 are installed on the connecting column 2, the positioning blocks 21 are inserted into the positioning holes 201 on the connecting column 2, which can provide support for the connection between the triangular plates 31 and the connecting column 2, thereby preventing the triangular plates 31 from sliding downward after the support beam 4 is installed.

[0026] like Figure 1 - Figure 3As shown, the connecting column 2 is provided with a connecting hole 202 on the side close to the base 1, and a limiting hole 203 is provided on the side of the connecting hole 202 away from the base 1. The side of the base 1 close to the connecting column 2 and the side of the connecting column 2 away from the base 1 are both fixedly connected with a connecting block 11, and the sides of the two connecting blocks 11 away from the base 1 are both fixedly connected with limiting blocks 12, the limiting blocks 12 are plugged into the adjacent limiting holes 203, and the connecting blocks 11 are slidably connected to the inner walls of the adjacent connecting holes 202. When installing the connecting column 2 and the base 1, the limiting holes 203 and the connecting holes 202 are put on the connecting blocks 11 and the limiting blocks 12 to complete the installation connection. At the same time, multiple connecting columns 2 can be spliced ​​together in this connection method. When heightening is required, a higher steel structure support can be completed by splicing multiple connecting columns 2 together.

[0027] like Figure 1 - Figure 3 As shown, the stop block 12 and the stop hole 203 are asymmetrically designed. The asymmetrical design can prevent the connection column 2 from rotating after the stop block 12 is connected to the stop hole 203, thereby improving the connection stability.

[0028] like Figure 1 - Figure 3 As shown, a plug hole 101 is formed through one side of the connection block 11, and a plug 13 is slidably connected to the inner wall of the plug hole 101, and both ends of the plug 13 penetrate the outer wall of the adjacent connection column 2 and are slidably connected thereto. After the connection column 2 and the base 1 are installed and connected, the plug 13 is inserted into the plug hole 101 between the connection column 2 and the connection block 11 to prevent the connection from being disconnected. At the same time, when multiple connection columns 2 are spliced ​​and heightened, the plug 13 is also used for plugging, thereby improving the stability of the overall steel structure connection.
