Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a construction safety scaffolding structure with a self-locking function. Background Technology

[0002] Scaffolding is an important temporary facility used for personnel operations, material storage, and structural support in construction, and is widely used in the construction of high-rise buildings, bridges, municipal works, and industrial plants. Currently, most horizontal and vertical members of scaffolding are connected using couplers, pins, or welding. However, traditional coupler structures generally suffer from cumbersome assembly procedures, poor fixing reliability, and the risk of falls if connections loosen. Furthermore, workers find it difficult to complete connection operations quickly and safely in high-altitude working environments. In addition, some scaffolding lacks detachable modular connection methods when adjusting height or expanding structure, resulting in inflexible use and high transportation and maintenance costs. Especially in scenarios involving rapid construction and frequent disassembly / reassembly, existing connection structures generally lack automatic reset and self-locking capabilities, making them prone to loosening under vibration, impact, or eccentric loading conditions. Therefore, this paper proposes a construction safety scaffolding structure with a self-locking function to address the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a construction safety scaffold structure with a self-locking function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A construction safety scaffold structure with self-locking function includes a horizontal bar structure and a vertical bar structure. The horizontal bar structure is equipped with a locking structure with a self-locking mechanism on both sides, and the vertical bar structure is equipped with an installation plate structure on the outside. The horizontal bar structure and the vertical bar structure are detachably connected by the locking structure and the installation plate structure.

[0006] Preferably, the vertical rod structure includes multiple vertical rod bodies, and a sleeve is provided at the connection between adjacent vertical rod bodies, with both ends of the sleeve respectively sleeved to the vertical rod body, and a locking structure is installed at the connection between the sleeve and the vertical rod body.

[0007] Preferably, the locking structure includes a locking nut, both ends of the vertical rod body are provided with a first thread for connection and fixation, both ends of the sleeve are provided with a second thread for connection and fixation, and the upper and lower ends of the inner side of the locking nut are provided with threaded holes corresponding to the first thread of the vertical rod body and the second thread of the sleeve, respectively, and the locking nut is helically connected to the vertical rod body and the sleeve through the threaded holes, the first thread and the second thread, respectively.

[0008] Preferably, the crossbar structure includes a crossbar body and a connecting nut. Both ends of the crossbar body and one end of the locking structure are provided with a third thread, and a connecting nut for connection and fixation is installed on the outer side of the third thread.

[0009] Preferably, the outer side of the vertical rod structure is equipped with a plurality of mounting plate structures for connecting the locking structure, and the mounting plate structures are detachably and movably mounted on the outer side of the vertical rod body of the vertical rod structure.

[0010] Preferably, the mounting plate structure includes a mounting plate body, which is sleeved on the outside of the vertical rod body. The outside of the vertical rod body is evenly provided with a fourth thread, and a fastening nut is installed on the outside of the fourth thread. There are two fastening nuts, which are respectively installed on both sides of the mounting plate body.

[0011] Preferably, the locking structure includes a fixed base and a connecting rod, and one side of the connecting rod is connected to the crossbar structure. The fixed base and the mounting plate body of the mounting plate structure are both provided with locking holes. A locking pin that can automatically reset slides inside the locking hole, and the locking pin is inclined on the side near the vertical bar structure.

[0012] Preferably, there are four fixing seats, and the fixing seats are evenly installed on the outer side of the mounting plate body, with the outer sides of adjacent fixing seats fitting together.

[0013] Preferably, a gantry frame is installed on the upper side of the locking pin, an inner rod is installed on the lower side of the gantry frame, a connecting cylinder is installed on the other side of the inner rod, and the other end of the connecting cylinder is fixed to the locking pin.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In this invention, the coordinated operation of the horizontal bar structure, vertical bar structure, locking structure, and mounting plate structure achieves rapid engagement and automatic self-locking between the horizontal and vertical bars. The vertical bar structure employs a multiple fixing method—sleeve-thread-locking nut—ensuring reliable and stable height adjustment. The fourth thread and fastening nut on the outer side of the mounting plate enable rapid positioning and anti-slip of the mounting plate on the vertical bar. The third thread and connecting nut at the end of the horizontal bar ensure the firmness of the connection between the horizontal bar and the locking structure. The locking structure's internal locking pin, return spring, gantry frame, inner rod, and pull rope ring assembly allow the locking pin to automatically reset and tilt into the locking hole of the mounting plate when not pulled, achieving a stable oblique self-locking effect and effectively preventing loosening. Disassembly is achieved quickly by pulling the rope, significantly improving operational efficiency. Attached Figure Description

[0024] Example 1: Please refer to Figure 1-6 The present invention provides a technical solution:

[0025] A construction safety scaffolding structure with self-locking function includes a horizontal bar structure 1, a vertical bar structure 2, a locking structure 3, and an installation plate structure 4. Through the cooperation between the various structural modules, the scaffolding can be quickly erected, reliably self-locked, and easily disassembled.

[0026] The vertical rod structure 2 is composed of multiple vertical rod bodies 21 spliced ​​together, and each vertical rod body 21 has a first thread 24 machined at its end. The sleeve 22 used to connect adjacent vertical rod bodies is a hollow cylindrical part, and a second thread 25 is machined on the outer side of both ends of the sleeve 22.

[0027] During construction, the end of the vertical rod body 21 is inserted into the second thread 25 at both ends of the sleeve 22, so that the two vertical rod bodies 21 are mated inside the sleeve 22. Then, the locking nut 23 is screwed onto the joint between the vertical rod body 21 and the sleeve 22, and the locking nut 23 is threaded into the first thread 24 and the second thread 25 through the threaded holes at both ends, thus achieving axial locking of the connection position. This structure effectively prevents the vertical rod body from loosening under pressure or vibration, and improves the overall vertical load-bearing stability.

[0028] The mounting plate structure 4 is installed on the outside of the vertical rod body 21, and it serves as the snap-fit ​​interface for the locking structure 3. The outer side of the vertical rod body 21 is uniformly machined with fourth threads 43. By fitting the mounting plate body 41 onto the vertical rod body 21, and then screwing two fastening nuts 42 onto both sides of the mounting plate body 41, the mounting plate body 41 is clamped by tightening the fastening nuts 42, thus firmly positioning it in the designated position on the vertical rod body 21.

[0029] The distribution of the fourth thread 43 allows for flexible adjustment of the height of the mounting plate structure 4 on the vertical rod, enabling an adjustable arrangement of the scaffolding platform height and making the lateral connection more flexible.

[0030] The crossbar structure 1 includes a crossbar body 11 and a connecting nut 12 at its ends. The crossbar body 11 has third threads 13 machined at both ends for threaded connection with the connecting nut 12. When the crossbar structure 1 is connected to the locking structure 3, the crossbar body 11 is axially locked by tightening the connecting nut 12, ensuring that the crossbar structure does not slip or loosen under stress.

[0031] The locking structure 3 is the core locking unit of the present invention, mainly including a fixed base 31, a connecting rod 32, a locking pin 33, a return spring 35, an inner rod 36, a gantry frame 37, a connecting cylinder 34, a pull rope 38, and a pull ring 39.

[0032] The fixing seats 31 are evenly distributed on the outer circumferential position of the mounting plate body 41, and the outer surfaces of each fixing seat 31 fit together to form a stable locking mounting assembly. One end of the connecting rod 32 is fixed to the connecting nut 12 of the crossbar structure 1, thereby realizing the overall connection between the crossbar structure 1 and the vertical bar structure 2.

[0033] Locking holes are provided on both the fixed base 31 and the mounting plate body 41 to accommodate the locking pin 33. The locking pin 33 is arranged at an angle, and its tail is fixedly connected to the connecting cylinder 34. The connecting cylinder 34 is connected to the gantry frame 37 through the inner rod 36, and the gantry frame 37 is fixed above the fixed base 31. A return spring 35 is provided on the outer side of the inner rod 36 to automatically push the locking pin 33 back to the locked position after it is pulled.

[0034] The pull rope 38 extends from one side of the locking pin 33 and passes through the gantry 37. A pull ring 39 is provided at its end. Construction workers can control the contraction and release of the locking pin 33 by pulling the pull ring 39.

[0035] During scaffolding erection, the operator moves the horizontal bar structure 1 so that the locking structure 3 aligns with the mounting plate structure 4 on the vertical bar structure 2. When the horizontal bar structure 1 is advanced horizontally, the tip of the locking pin 33 first contacts the mounting plate body 41 and compresses the return spring 35 under the action of forward thrust, causing the locking pin 33 to retract to one side of the connecting cylinder 34;

[0036] When the locking hole of the latch structure 3 coincides with the locking hole of the mounting plate structure 4, the locking pin 33 automatically pops out and inserts into the locking hole of the mounting plate structure 4 under the action of the return spring 35, realizing automatic self-locking connection. This process eliminates the need for manual insertion of the pin, making it quick and safe, and particularly suitable for high-altitude work environments.

[0037] When disassembly is required, the construction worker pulls the pull ring 39, which moves the inner rod 36 and connecting cylinder 34 via the pull rope 38, causing the locking pin 33 to retract, thereby releasing the locking state between the horizontal bar structure 1 and the vertical bar structure 2 and enabling quick disassembly. After releasing the pull ring 39, the return spring 35 will automatically return the locking pin 33 to its initial position, facilitating the next erection.
