Description

Technical Field

[0001] This utility model belongs to the field of steel structure construction technology, specifically, it relates to a locking device for building steel structure construction. Background Technology

[0002] When two adjacent square steel pipes are connected and locked, they are inserted into a connecting sleeve and fixed with multiple bolts. While this method ensures a secure lock, the clamping force is primarily transmitted through the localized pipe wall area in contact with the bolt head and nut. Due to the shape of square steel pipes, this force cannot be evenly distributed around the circumference as in round pipes. The portion of the pipe wall near the bolt bears greater pressure, while the portion further away experiences relatively less stress. This uneven stress distribution can easily lead to excessive stress in localized areas, which can cause deformation and damage over time due to localized stress concentration. This reduces the durability of the lock on the two adjacent square steel pipes.

[0003] In view of this, this utility model is hereby proposed. Utility Model Content

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0005] A steel structure construction locking device includes two square structural steel pipes and a connecting sleeve disposed between the two square structural steel pipes. The two side walls of the two square structural steel pipes opposite to the connecting sleeve are respectively provided with multiple connecting holes. The device also includes a locking component disposed in the connecting sleeve for connecting and locking the two square structural steel pipes.

[0006] The locking assembly includes a partition plate fixedly connected to the inner wall of the connecting sleeve. Two support plates are connected to the two sides of the partition plate near the square structural steel pipe through a guide assembly. Multiple threaded holes are opened on the side of the four support plates near the inner wall of the connecting sleeve. Each threaded hole is threaded with a bolt. Each threaded hole is matched with a connecting hole. The connecting sleeve is provided with a driving assembly for driving two adjacent support plates.

[0007] The driving assembly includes a driving plate slidably connected to a connecting sleeve. Two driving pins are fixedly connected to one side of the driving plate. Sliding holes are opened on the opposite sides of the two supporting plates. The opposite ends of the driving plate are slidably connected to the sliding holes. Driving oblique holes are opened through the inner walls of the two sliding holes near the driving pins. The two driving pins are slidably connected to the driving oblique holes. The connecting sleeve is provided with a pushing assembly for pushing the driving plate.

[0008] The guide assembly includes a dovetail groove formed on the side of the partition near the support plate, and a dovetail plate is slidably connected to the dovetail groove. One end of the dovetail plate is connected to the support plate.

[0009] The pushing assembly includes a pushing hole opened on the side of the partition near the drive plate. A pushing plate is slidably connected to the pushing hole. One end of the pushing plate is connected to the drive plate. An inclined surface is opened on the side of the pushing plate near the drive pin.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0022] Example 1

[0023] Please see Figures 1-4 The diagram shows a steel structure construction locking device, which includes two square steel pipes 101 and a connecting sleeve 102 disposed between the two square steel pipes 101. The two side walls of the two square steel pipes 101 and the connecting sleeve 102 are respectively provided with multiple connecting holes 103. The device also includes a locking component disposed in the connecting sleeve 102 for connecting and locking the two square steel pipes 101.

[0024] The locking assembly includes a partition 203 fixedly connected to the inner wall of the connecting sleeve 102. Two support plates 201 are connected to the two sides of the partition 203 near the square structural steel pipe 101 via a guide assembly. Multiple threaded holes 202 are opened on the side of the four support plates 201 near the inner wall of the connecting sleeve 102. Each threaded hole 202 is threaded with a bolt 204. Each threaded hole 202 is matched with the connecting hole 103. The connecting sleeve 102 is provided with a drive assembly for driving two adjacent support plates 201.

[0025] It should be noted that the locking component, in conjunction with the drive and push components, supports the locking point between the connecting sleeve 102 and the square structural steel pipe 101, thereby reducing the accumulation of local stress. This ensures the secure locking of the square structural steel pipe 101 while reducing the risk of deformation and damage due to stress concentration at the locking point of the bolt 204 on the connecting sleeve 102 and the square structural steel pipe 101, thus improving the stability and durability of the locking of the square structural steel pipe 101.

[0026] It is worth noting that the inner wall of the connecting sleeve 102 is matched with the outer wall of the square structural steel pipe 101.

[0027] Please see Figure 2 and Figure 3 The driving assembly shown in the figure includes a driving plate 301 slidably connected to the connecting sleeve 102. Two driving pins 302 are fixedly connected to one side of the driving plate 301. Sliding holes 303 are opened on the opposite side of the two support plates 201. The opposite ends of the driving plate 301 are slidably connected to the sliding holes 303. Driving inclined holes 304 are opened through the inner wall of the two sliding holes 303 near the driving pins 302. The two driving pins 302 are slidably connected to the driving inclined holes 304. The connecting sleeve 102 is provided with a pushing assembly for pushing the driving plate 301.

[0028] It should be noted here that the drive components are configured to move the two adjacent support plates 201 closer to or further apart from each other.

[0029] It is worth noting that there is a gap between the side wall of the drive plate 301 and the bottom wall of the sliding hole 303, which is sufficient to meet the movement requirements of the support plate 201.

[0030] Please see Figure 2 and Figure 3 The guide component shown in the figure includes a dovetail groove 401 opened on the side of the partition 203 near the support plate 201. The dovetail groove 401 is slidably connected to a dovetail plate 402, and one end of the dovetail plate 402 is connected to the support plate 201.

[0031] It should be noted here that the guide components are used to guide and limit the movement of the support plate 201.

[0032] Working principle: When connecting and locking two adjacent square structural steel pipes 101, first place the connecting sleeve 102 between the two adjacent square structural steel pipes 101, and then insert one end of the two adjacent square structural steel pipes 101 into the connecting sleeve 102, and make one end abut against the surface of the partition 203 inside the connecting sleeve 102.

[0033] After inserting the two square steel pipes 101 into the connecting sleeve 102, the driving plate 301 is moved by the pushing assembly. During the movement of the driving plate 301, the two support plates 201 move away from each other due to the interaction force of the two driving pins 302 and the driving inclined hole 304, as well as the guiding action of the guiding assembly. As the driving plate 301 continues to move, when the side of the two support plates 201 that moves away from each other abuts against the inner wall of the square steel pipe 101, the movement of the driving plate 301 can be stopped. At this time, the bolts 204 can be inserted into the connecting holes 103 on the side walls of the connecting sleeve 102 and the square steel pipe 101. The connection and locking of the square structural steel pipe 101 are achieved through the threaded engagement of the bolt 204 and the threaded hole 202 on the side wall of the support plate 201. During the screwing and locking process of the bolt 204, the support plate 201 supports the locking point of the connecting sleeve 102 and the square structural steel pipe 101, reducing the accumulation of local stress. This ensures the firmness of the connection and locking of the square structural steel pipe 101 while reducing the risk of deformation and damage due to stress concentration at the locking point of the bolt 204 on the connecting sleeve 102 and the square structural steel pipe 101, thereby improving the stability and durability of the locking of the square structural steel pipe 101.

[0034] Example 2

[0035] Please see Figure 3 and Figure 4 This embodiment further illustrates Example 1. The push assembly shown in the figure includes a push hole 501 opened on the side of the partition 203 near the drive plate 301. A push plate 502 is slidably connected to the push hole 501. One end of the push plate 502 is connected to the drive plate 301. An inclined surface 503 is opened on the side of the push plate 502 near the drive pin 302. A push rod 504 is threadedly connected to the side of the connecting sleeve 102 near the inclined surface 503. One end of the push rod 504 near the drive plate 301 is opposite to the inclined surface 503. A rotating hole 505 is opened on the other end of the push rod 504. The rotating hole 505 is a regular hexagon.

[0036] It should be noted here that: by setting up the push component, when the push rod 504 is rotated by using an Allen wrench, the push rod 504 moves closer to the push plate 502 under the action of thread meshing transmission. When one end of the push rod 504 abuts against the inclined surface 503 on the push plate 502, the push plate 502 will move closer to the partition 203 under the interaction force and the guiding action of the push hole 501, thereby driving the drive plate 301 to move closer to the partition 203.

[0037] Example 3

[0038] Please see Figure 4This embodiment is a further explanation of other embodiments. In the figure, the two push plates 502 are fitted with springs 6 on their side walls. The two ends of the springs 6 are respectively connected to the drive plate 301 and the partition plate 203.

[0039] It should be noted here that: due to the setting of spring 6, when the two connected square structural steel pipes 101 are disassembled, the push plate 502 is released, and under the elastic action of spring 6, the drive plate 301 will move away from the partition plate 203, thereby driving the two support plates 201 to move closer to each other.
