Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and more specifically, to a modular building steel structure connection node that is easy to assemble. Background Technology

[0002] Prefabricated steel structure buildings are buildings constructed using steel as the basic material. Compared with traditional buildings, prefabricated steel structure buildings have advantages such as light weight, high strength, good seismic performance, low cost, less susceptibility to climate conditions, short construction period, and convenient construction. As the most critical component of prefabricated steel structures, the form and performance of joints directly affect the degree of industrialization and structural form of the structure.

[0003] Chinese patent application CN202120195826.3 discloses a connection node for a steel structure building, comprising several columns and several beams connecting adjacent columns. One end of each beam is connected to the side face of a column via two connectors arranged along the column's axial direction. Each connector further includes a first connecting portion and a second connecting portion. This utility model, through the design of the connectors, enables stable connections between columns and beams at different locations, simplifying the manufacturing process and facilitating on-site installation.

[0004] However, as can be seen from the accompanying drawings in the specification, when installing an I-shaped crossbar on the side of the column, the connection node requires two connection nodes to be used for fixing, and each connection node requires eight bolts for fixing. This will affect the installation efficiency during installation and use, and will increase the number of bolts used and increase the installation cost. Therefore, a modular building steel structure connection node that is easy to assemble is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a modular building steel structure connection node that is easy to assemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular building steel structure connection node that is easy to assemble, including a bonding plate set on one side of the column. Limiting horizontal plates are symmetrically fixedly connected to both ends of the bonding plate on the side away from the column. The two limiting horizontal plates can support and limit the connected I-shaped crossbar. Limiting vertical plates are symmetrically fixedly connected to both ends of the bonding plate. The combination of the limiting vertical plates and the bonding plate can be secured to the column for easy installation and fixing. Two positioning horizontal plates are fixedly connected to the side of the bonding plate near the limiting horizontal plates. A reinforcing diagonal bar is fixedly connected to the top of the positioning horizontal plate. The reinforcing diagonal bar supports the position of the positioning horizontal plate, improving the stability of the second mounting hole. The positioning horizontal plates limit the crossbar of the I-shaped crossbar, further improving the support strength of the I-shaped crossbar and preventing it from tilting.

[0007] The surfaces of the limiting horizontal plate and the positioning horizontal plate are each provided with a first mounting hole, and the middle part of the limiting vertical plate is provided with a second mounting hole. An I-shaped horizontal bar is provided on the side of the bonding plate near the limiting horizontal plate. The I-shaped horizontal bar can be easily fixedly connected to the limiting horizontal plate and the positioning horizontal plate through the first mounting hole, and the limiting vertical plate can be easily fixed to the column through the second mounting hole, which is convenient for installation and use.

[0008] Preferably, the cross-sectional shape of the bonding plate is set to "T" shape, and the limiting upright plate is located on the side away from the limiting horizontal plate. By using the bonding plate and the limiting horizontal plate, when the two bonding plates are combined, the second inversion will not affect the combined installation and use.

[0009] Preferably, there are two first mounting holes on the surface of the limiting horizontal plate. The two first mounting holes on the surface of the limiting horizontal plate and the first mounting hole on the surface of the positioning horizontal plate are on the same axis. The first mounting holes facilitate the fixed connection of a long screw through the first mounting holes on the surfaces of the limiting horizontal plate and the positioning horizontal plate with the I-shaped horizontal bar.

[0010] Preferably, the two ends of the reinforcing diagonal brace are fixedly connected to the walls of the positioning horizontal plate and the bonding plate, respectively. The reinforcing diagonal brace is set between the two positioning horizontal plates. By reinforcing the diagonal brace, the stability of the positioning horizontal plate is improved, thereby improving the support stability of the positioning horizontal plate for the I-shaped horizontal bar.

[0011] Preferably, the diameters of the first mounting holes of the second mounting holes are the same, and the axis of the second mounting hole is on the same horizontal plane as the top wall of the positioning plate, which facilitates installation and use without requiring changes to the screw size, making it universally applicable and convenient to use.

[0012] Preferably, the two limiting horizontal plates are located on both sides of the I-shaped horizontal bar, and the positioning horizontal plate is located inside the grooves on both sides of the I-shaped horizontal bar. The limiting horizontal plates and the positioning horizontal plates cooperate to limit and support the I-shaped horizontal bar, making it convenient to connect the column to the I-shaped horizontal bar for use.

[0013] Preferably, the distance between the side wall of the positioning horizontal plate away from the reinforcing diagonal bar and the wall of the bottom limiting horizontal plate is the same as the thickness of the horizontal plate of the I-shaped horizontal bar, and the distance between the two limiting vertical plates is adapted to the width of the column. Through the cooperation of the positioning horizontal plate and the limiting horizontal plate, the I-shaped horizontal bar can be limited, thereby improving the stability of the I-shaped horizontal bar installed on the column.

[0014] Preferably, the bonding plate, the limiting horizontal plate, and the limiting vertical plate are integrally bent. The positioning horizontal plate and the reinforcing diagonal bar are fixed to the bonding plate by welding. The height of the limiting vertical plate is half the height of the bonding plate. By integrally bending the bonding plate, the limiting vertical plate, and the limiting horizontal plate, the overall strength can be improved. Furthermore, the limiting vertical plate ensures that when one bonding plate is installed on the column, it does not affect the installation and fixing of the other bonding plate, facilitating combined installation and use.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model firstly supports and limits the connected I-shaped crossbar by using two limiting horizontal plates. The combination of the limiting vertical plate and the bonding plate can be clamped onto the column for easy installation and fixation. The position of the positioning horizontal plate is supported by the reinforcing diagonal bar, and the horizontal plate of the I-shaped crossbar is limited by the positioning horizontal plate, which further improves the support strength of the I-shaped crossbar and prevents the I-shaped crossbar from tilting. The first mounting hole allows a long screw to pass through the first mounting hole on the surface of the limiting horizontal plate and the positioning horizontal plate and fix it to the I-shaped crossbar, reducing the number of bolts and not affecting the stability of the installation connection.

[0017] 2. This utility model also allows for the installation and fixation of one end of the I-shaped crossbar by setting a connecting node. When installing another I-shaped crossbar and the connecting node in the vertical direction, the connecting node can be installed by simply reversing the connection node, without affecting the horizontal effect of the two I-shaped crossbars. It also provides an automatic alignment effect during installation, improving the performance. The overall strength can be improved by bending the bonding plate, the limiting upright plate, and the limiting horizontal plate together.

[0018] In summary, the interaction of the above-mentioned multiple effects can improve the overall strength of the connection node, while enabling a single connection node to install and fix an I-shaped crossbar without affecting the stability of the installation connection. At the same time, it can reduce the amount of bolts used and improve installation efficiency. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As attached Figure 1-4 The modular steel structure connection node shown is easy to assemble. It includes a bonding plate 1 set on one side of the column. The two ends of the bonding plate 1 away from the column are symmetrically fixed with limiting horizontal plates 2. The two limiting horizontal plates 2 can support and limit the connected I-shaped crossbar 8. The two ends of the bonding plate 1 are symmetrically fixed with limiting vertical plates 3. The combination of the limiting vertical plates 3 and the bonding plate 1 can be clamped on the column for easy installation and fixing. The side of the bonding plate 1 near the limiting horizontal plates 2 is fixedly connected with two positioning horizontal plates 4. The top of the positioning horizontal plates 4 is fixedly connected with a reinforcing diagonal bar 5. The reinforcing diagonal bar 5 supports the position of the positioning horizontal plates 4, improves the stability of the second mounting hole 7, and limits the horizontal plate of the I-shaped crossbar 8 through the positioning horizontal plates 4, further improving the support strength of the I-shaped crossbar 8 and preventing the I-shaped crossbar 8 from tilting.

[0026] The surfaces of the limiting horizontal plate 2 and the positioning horizontal plate 4 are both provided with first mounting holes 6, and the middle part of the limiting vertical plate 3 is provided with a second mounting hole 7. The side of the bonding plate 1 near the limiting horizontal plate 2 is provided with an I-shaped horizontal bar 8. The I-shaped horizontal bar 8 can be easily fixedly connected to the limiting horizontal plate 2 and the positioning horizontal plate 4 through the first mounting hole 6, and the limiting vertical plate 3 can be easily fixed to the column through the second mounting hole 7, which is convenient for installation and use.

[0027] As attached Figure 1-4As shown, the cross-sectional shape of the bonding plate 1 is set to "T" shape. The limiting upright plate 3 is located on the side away from the limiting horizontal plate 2. There are two first mounting holes 6 on the surface of the limiting horizontal plate 2. The two first mounting holes 6 on the surface of the limiting horizontal plate 2 are on the same axis as the first mounting holes 6 on the surface of the positioning horizontal plate 4. The two ends of the reinforcing diagonal rod 5 are fixedly connected to the positioning horizontal plate 4 and the wall of the bonding plate 1, respectively. The reinforcing diagonal rod 5 is set between the two positioning horizontal plates 4. The diameter of the first mounting hole 6 of the second mounting hole 7 is the same as that of the first mounting hole 6. The axis of the second mounting hole 7 is on the same axis as the first mounting hole 6 of the positioning horizontal plate 4. The top wall of the horizontal plate 4 is on the same horizontal plane. Two limiting horizontal plates 2 are located on both sides of the I-shaped horizontal bar 8. The positioning horizontal plate 4 is located inside the grooves on both sides of the I-shaped horizontal bar 8. The distance between the side wall of the positioning horizontal plate 4 away from the reinforcing diagonal bar 5 and the wall of the bottom limiting horizontal plate 2 is the same as the thickness of the horizontal plate of the I-shaped horizontal bar 8. The distance between the two limiting vertical plates 3 is adapted to the width of the column. The bonding plate 1, the limiting horizontal plate 2, and the limiting vertical plate 3 are integrally bent. The positioning horizontal plate 4 and the reinforcing diagonal bar 5 are fixed to the bonding plate 1 by welding. The limiting vertical plate 3... The height is half the height of the bonding plate 1. The bonding plate 1 and the limiting horizontal plate 2 allow for assembly without affecting the use of the two bonding plates 1 by inverting the second one. A long screw passes through the first mounting hole 6 on both the limiting horizontal plate 2 and the positioning horizontal plate 4, and is then fixedly connected to the I-shaped horizontal bar 8. The stability of the positioning horizontal plate 4 is improved by the reinforcing diagonal bar 5, thereby enhancing the support stability of the positioning horizontal plate 4 for the I-shaped horizontal bar 8. This design facilitates installation and use without requiring changes to the screw size, making it universally applicable and convenient to use. The I-shaped crossbar 8 is limited and supported by the cooperation of the limiting horizontal plate 2 and the positioning horizontal plate 4, which facilitates the connection between the column and the I-shaped crossbar 8. The positioning horizontal plate 4 and the limiting horizontal plate 2 can limit the I-shaped crossbar 8, improving the stability of the I-shaped crossbar 8 when installed on the column. The overall strength can be improved by bending the bonding plate 1, the limiting vertical plate 3, and the limiting horizontal plate 2 as a whole. The limiting vertical plate 3 can also ensure that when one bonding plate 1 is installed on the column, it does not affect the installation and fixation of the other bonding plate 1, which is convenient for combined installation and use.

[0028] The working principle of this utility model is as follows: When in use, the bonding plate 1 is clamped onto the column by the limiting plate 3, and the bolt is inserted into the second mounting hole 7 and extends to the column, so as to fix the bonding plate 1 onto the column.

[0029] Then, insert one end of the I-shaped crossbar 8 between the two limiting cross plates 2, and position the positioning cross plate 4 inside the recesses on both sides of the I-shaped crossbar 8. Then, insert a screw into the first mounting hole 6, so that the screw passes through the wall of the I-shaped crossbar 8 and through the middle of the first mounting hole 6 on the surface of the positioning cross plate 4 to fix the I-shaped crossbar 8.

[0030] When another bonding plate 1 needs to be installed, the second bonding plate 1 is inverted so that the limiting plate 3 is on top of the first limiting plate 3. The above installation is repeated to fix the I-shaped crossbar 8 to one side of the bonding plate 1 for easy use.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
