Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a scaffolding connection structure for building construction. Background Technology

[0002] Scaffolding is a commonly used working platform in construction. Traditional connections rely on fasteners and multiple screws for fixing, which requires repeated tightening, is time-consuming and inefficient, and screws and fasteners are easily lost, resulting in poor connection firmness and unstable fixing effect.

[0003] Patent document CN210508345U discloses two connected disc fasteners. Each disc fastener includes: a left clamp, one end of which protrudes to form a left connecting ear with a pin hole; the other end of the left clamp protrudes to form a left connecting portion with a bolt hole; a right clamp, one end of which protrudes to form at least one right connecting ear with a pin hole; the other end of the right clamp protrudes to form a right connecting portion with a bolt hole; a circular groove is formed radially along the nut, and an elongated hole is formed radially along the bolt, located at the other end of the bolt; a fixing handle can be inserted sequentially into the circular groove and the elongated hole. During use, the bolt is first pre-tightened, and then the fixing handle is rotated for a second fixation, which is relatively time-saving and labor-saving, offering advantages such as high efficiency, reduced labor, and low cost.

[0004] However, the invention has the following shortcomings: the disc buckle still requires bolts and handles for fixing, relies on tools, has complicated steps, and the parts are scattered and easily lost or damaged; it relies on bolts and pins for locking, which is easy to loosen and has no self-locking function, resulting in insufficient security; it only supports a single disc buckle connection, has poor versatility, is cumbersome to disassemble, and has low overall efficiency. Summary of the Invention

The operation is simple and convenient, significantly shortening the erection and dismantling time and greatly improving construction efficiency. There is no component damage during the assembly and disassembly process, and all the clips, sliders, and compression springs can be repeatedly reset and reused, resulting in a high component turnover rate. This effectively reduces material costs and labor input, and solves the problems of easy loss of accessories, cumbersome fixing, and low efficiency of traditional coupler-type scaffolding. It combines convenience, economy, and durability. Attached Figure Description

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This invention provides an improved connection structure for scaffolding used in building construction. The technical solution of this invention is as follows:

[0027] like Figures 1 to 4 As shown, this embodiment of the invention provides a scaffolding connection structure for building construction, including a cross-shaped connecting rod 1. The cross-shaped connecting rod 1 integrates horizontal and vertical connection functions. Components such as clips, sliders, and frustums are embedded or fitted together. The nodes are small in size and the stress is evenly distributed, making it suitable for various scaffolding erection scenarios. It also includes a first cavity 2, fixing components, and connecting components.

[0028] The first cavity 2 is respectively opened on the longitudinal support of the cross connecting rod 1. A cross rod 3 is fixedly connected inside the first cavity 2. A trapezoidal slider 5 is provided inside the first cavity 2.

[0029] The fixing assembly includes fixing rods 12 fixedly installed at both ends of the transverse support of the cross connecting rod 1, and a sleeve 10 is fixedly installed on each fixing rod 12;

[0030] The connecting assembly includes a transverse connecting pipe 21 that is slidably mounted on the sleeve 10, and a trapezoidal fixing block 23 on both ends of the longitudinal support of the cross connecting rod 1. A longitudinal connecting rod 22 is fixedly installed at one end of each trapezoidal fixing block 23.

[0031] Furthermore, a pair of sliding grooves 25 are provided on the cross connecting rod 1, and through holes 28 are provided on both sides of each first cavity 2. A pair of sliding plates 6 are slidably sleeved on the outside of the crossbar 3. A first locking block 4 is fixedly installed at one end of each sliding plate 6. A second locking groove 27 is provided on the trapezoidal fixing block 23. The first locking block 4 is located inside the second locking groove 27 and the through hole 28. A first compression spring 7 is fixedly installed between the first cavity 2 and the sliding plate 6. The first compression spring 7 is sleeved on one end of the crossbar 3. A double locking structure is adopted, in which the first locking block 4 is engaged with the second locking groove 27 and the second locking block 15 is engaged with the first locking groove 20. With the help of multiple sets of compression springs, the automatic reset and locking are achieved, and the nodes are not loose or shifting, resulting in higher overall frame safety.

[0032] Furthermore, a trapezoidal slider 5 is positioned between a pair of first locking blocks 4. An L-shaped slide rod 9 is fixedly installed at one end of the trapezoidal slider 5. One end of the L-shaped slide rod 9 passes through the cross connecting rod 1 and is slidably installed inside the slide groove 25. A second compression spring 8 is sleeved on the other end of the L-shaped slide rod 9. The two ends of the second compression spring 8 are fixedly connected to the trapezoidal slider 5 and the inner wall of the first cavity 2, respectively. Assembly and disassembly can be completed by relying on the cooperation of the trapezoidal slider 5, the L-shaped slide rod 9, the truncated cone and the locking blocks, without the need for bolts, nuts, wrenches and other accessories, which greatly improves the efficiency of assembly and disassembly.

[0033] Furthermore, a first frustum 11 is fixedly installed on the outside of the fixing rod 12 and one end of the sleeve 10. A second frustum 13 is slidably sleeved on the outside of the fixing rod 12. A groove 24 is provided on the sleeve 10. A third compression spring 14 is fixedly installed between the second frustum 13 and the inner wall of the groove 24. The third compression spring 14 is sleeved on the fixing rod 12. One end of the second frustum 13 is fitted and connected to the cross connecting rod 1.

[0034] Furthermore, the transverse connecting pipe 21 is fitted onto the first frustum 11, the fixing rod 12, and the second frustum 13. Each transverse connecting pipe 21 has a pair of second cavities 16 on its inner wall and a pair of first slots 20 on its outer wall. The trapezoidal fixing block 23 fits into the transverse connecting pipe 21. A longitudinal connecting rod 22 is fixedly installed at one end of the trapezoidal fixing block 23. A slot 26 is provided on the longitudinal connecting rod 22. The slot 26 fits into the longitudinal support of the cross connecting rod 1. The trapezoidal structure and the compression spring cooperate to form an anti-disengagement self-locking mechanism. Even if subjected to vibration or lateral force, the locking block is not easy to disengage, thus improving the safety of high-altitude operations.

[0035] Furthermore, a trapezoidal second locking block 15 is provided in the second cavity 16. A square slide rod 18 is fixedly installed at one end of the second locking block 15. One end of the square slide rod 18 passes through the transverse connecting pipe 21 and is located inside the first locking groove 20. A stop block 19 is fixedly installed at one end of the square slide rod 18. A fourth compression spring 17 is fixedly installed between the second locking block 15 and the second cavity 16. The fourth compression spring 17 is sleeved on the square slide rod 18. Pressing the stop block 19 can release the transverse locking, and pushing the L-shaped slide rod 9 can release the longitudinal locking. The assembly and disassembly are non-damaging, and the components can be reused multiple times, reducing construction costs.

[0036] The specific working principle is as follows: Before construction, preparatory work is carried out. The dimensions and appearance of components such as the cross connecting rod 1, the horizontal connecting pipe 21, the longitudinal connecting rod 22, and the trapezoidal fixing block 23 are checked one by one to ensure that there is no deformation, cracks, or defects. At the same time, the elasticity of the first compression spring 7, the second compression spring 8, the third compression spring 14, and the fourth compression spring 17 is checked to ensure that they are qualified. Scaffolding installation auxiliary tools are provided and the working surface is cleared to ensure operating space. Then, the connection node positions are determined according to the scaffolding erection plan, and the placement baseline of the cross connecting rod 1 is marked. During installation, the cross connecting rod 1 is first placed stably at the node position, and the horizontal and vertical directions are corrected to ensure that the orientation of the longitudinal and horizontal supports meets the erection requirements. The first cavity is then cleared. 2. Remove debris from the groove 25 and through hole 28. Then, insert the trapezoidal fixing block 23 at the end of the longitudinal connecting rod 22 into both ends of the longitudinal support rod of the cross connecting rod 1 through the slot 26, so that the trapezoidal fixing block 23 and the cross connecting rod 1 are tightly fitted to complete the initial positioning. Next, perform longitudinal connection locking. Push the L-shaped slide rod 9 along the groove 25 to drive the trapezoidal slider 5 to move in the first cavity 2, squeezing the two side slide plates 6 and the first locking block 4, so that the first locking block 4 compresses the first compression spring 7 and passes through the through hole 28 to lock into the second locking groove 27 of the trapezoidal fixing block 23. After releasing the L-shaped slide rod 9, the second compression spring 8 returns to its original position, and the trapezoidal slider 5 returns to its original position and locks, completing the rigid locking of the longitudinal connecting rod 22 and the cross connecting rod 1. Next, insert the transverse connecting tube 21 onto the outside of the fixing rod 12, the first frustum 11, and the second frustum 13, and push it along the axial direction of the sleeve 10 to the designed position to complete the pre-installation of the transverse connecting tube 21. Then, perform transverse connection locking. The inner wall of the transverse connecting tube 21 presses against the second locking block 15, compressing the fourth compression spring 17 to make the second locking block 15 retract into the second cavity 16. After the transverse connecting tube 21 is in place, the fourth compression spring 17 resets, and the second locking block 15 pops out and locks. At the same time, the third compression spring 14 pushes the second frustum 13 to press against the transverse connecting tube 21, achieving transverse double locking. Afterward, confirm that the first locking block 4 is fully embedded in the second locking groove 27, the second locking block 15 is fully locked, and the L-shaped slide rod 9 and the stop block 19 are not loose. After dynamic displacement, all compression springs are working normally and there are no gaps between components, complete the overall node inspection, and then follow the above steps to complete the installation of all connection nodes on the same floor and span of the scaffolding, ensuring that the nodes are evenly stressed and erected straight to form a stable frame structure; when disassembling, first press the stop block 19, push the square slide rod 18 to make the second locking block 15 retract into the second cavity 16, pull out the transverse connecting pipe 21 along the axis to complete the transverse disassembly, then push the L-shaped slide rod 9 to release the pressure of the trapezoidal slider 5 on the first locking block 4, and the first locking block 4 exits the second locking groove 27 under the action of the first compression spring 7, remove the longitudinal connecting rod 22 to complete the longitudinal disassembly, and finally classify and place the disassembled components, check their integrity, and keep them for later use or repair and reuse.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
