Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a protective support for building engineering. Background Technology

[0002] Construction engineering is a broad and complex field, mainly involving the construction of various types of buildings and their ancillary facilities. The engineering entities formed by the construction of various buildings and their ancillary facilities and the installation of supporting lines, pipelines and equipment meet people's needs for production, living, learning and public activities. During the construction process, protective supports are usually set up at the construction site. The protective supports can effectively isolate the construction site from the surrounding roads, residential areas, etc., reduce the impact of construction on the surrounding environment, and prevent non-construction personnel from entering the construction area, thus ensuring construction safety.

[0003] Existing protective supports for construction projects have shortcomings in design and function. First, traditional protective supports generally use multiple protective plates fixed together with bolts. This structure is too rigid and cannot flexibly adjust its width according to actual construction needs, resulting in extremely poor adaptability to construction areas of different widths. Often, custom-made or disassembled and reassembled supports are required, increasing construction costs and reducing work efficiency. Second, the bolt-fixing installation method is cumbersome and time-consuming, requiring specialized tools and multiple people working together. Especially in narrow or high-altitude environments, the installation process is not only inefficient but also poses safety hazards. Furthermore, during storage, the disassembled protective plates and support components are scattered and messy, occupying a large amount of storage space and making transportation and storage extremely inconvenient.

[0004] To address the aforementioned problems, this utility model proposes a protective support for building engineering. Utility Model Content

[0024] Please see Figure 1-5 This utility model provides a technical solution: a protective support for building engineering, including a fixed plate 1 and a movable plate 2. Slide grooves 3 are fixedly installed on both the upper and lower sides of the fixed plate 1, and the movable plate 2 is slidably positioned between two slide grooves 3. End plates 4 are fixedly installed on both sides of the movable plate 2, and limit rods 5 are slidably installed at both the upper and lower ends of the end plates 4. Multiple limit grooves 6 are evenly distributed inside the slide grooves 3, and the limit rods 5 are inserted into the corresponding limit grooves 6.

[0025] An adjustment assembly for controlling the movement of the limit rod 5 is provided on the end plate 4.

[0026] Furthermore, both the upper and lower ends of the end plate 4 are provided with connecting grooves 7, the limiting rod 5 is slidably installed inside the connecting groove 7, the connecting groove 7 is fixedly installed with a fixing block 8, and the connecting groove 7 is provided with a reset spring 9, the two ends of the reset spring 9 abutting against the limiting rod 5 and the fixing block 8 respectively.

[0027] Specifically, such as Figure 4-5 As shown, the adjustment assembly includes a take-up roller 10, a separator plate 11, a connecting rope 12, and a connecting shaft 13; an adjustment groove 14 is provided at the longitudinal middle position of the end plate 4, and the connecting grooves 7 are all connected to the interior of the adjustment groove 14; a cover plate 15 is fixedly installed on the outside of the adjustment groove 14; the take-up roller 10 is rotatably installed inside the adjustment groove 14, and the take-up roller 10 is divided into two take-up areas by the separator plate 11. The connecting rope 12 is wound on both take-up areas, and the end of the connecting rope 12 away from the take-up roller 10 is fixedly connected to the corresponding limit rod 5 through the connecting groove 7; the connecting rope 12 is slidably connected to the corresponding fixing block 8; the connecting shaft 13 is rotatably installed on the cover plate 15, and the connecting shaft 13 is fixedly connected to the connecting rope 12.

[0028] By adopting the above scheme, the components work together during the adjustment process. The dual-zone synchronous design of the winding roller 10 ensures the consistency of the movement of the limit rods 5 on both sides, so that the enclosure always maintains structural stability and airtightness.

[0029] Specifically, a rectangular rod 16 is fixedly installed on one end of the connecting shaft 13 away from the connecting rope 12. A sliding plate 17 is slidably installed on the outside of the rectangular rod 16. A limiting spring 18 is sleeved on the outside of the rectangular rod 16. One end of the limiting spring 18 is fixedly connected to the connecting shaft 13, and the other end of the limiting spring 18 is fixedly connected to the sliding plate 17. Support plates 19 are fixedly installed on both sides of the sliding plate 17. A positioning rod 20 is fixedly installed on the side of the support plate 19 away from the sliding plate 17. Multiple positioning holes 21 are evenly opened on the cover plate 15 around the axis of the connecting shaft 13. The positioning rod 20 is inserted into the positioning hole 21.

[0030] In this embodiment of the invention, an anti-detachment plate 22 is fixedly installed at the end of the rectangular rod 16 away from the connecting shaft 13 to prevent the sliding plate 17 from detaching from the rectangular rod 16.

[0031] In this embodiment of the invention: a support leg 23 is fixedly provided at the bottom end of the fixing plate 1, and a ground nail hole is provided on the support leg 23. The support leg 23 can be reinforced through the ground nail hole to improve the overall stability.

[0032] Working principle:

[0033] When adjusting the protective width, the operator first grasps the sliding plate 17 and pulls it horizontally outward. The axial displacement of the rectangular rod 16 causes the positioning rod 20 to completely disengage from the locking position of the positioning hole 21. During this process, the limiting spring 18 is stretched and stores elastic potential energy. Then, the sliding plate 17 is rotated clockwise or counterclockwise, causing the rectangular rod 16 to rotate synchronously, driving the connecting shaft 13 to rotate via a key connection. The rotational torque of the connecting shaft 13 is directly transmitted to the take-up roller 10, causing the two independent take-up zones separated by the separator disc 11 to synchronously take up the connecting rope 12. Under the traction of the connecting rope 12, the symmetrically arranged limiting rods 5 move in opposite directions along the connecting groove 7, forcing the return spring 9 to compress and store energy until the limiting rods 5 are completely released from the constraint of the limiting groove 6. At this point, the mechanical lock between the moving plate 2 and the slide groove 3 is completely released, and the operator can freely push and pull the moving plate 2 along the guide trajectory of the slide groove 3 to adjust the protective width.

[0034] Once adjusted to the desired width, the sliding plate 17 is released, and the return spring 9 releases its stored elastic potential energy. Through the reverse traction of the connecting rope 12, the limiting rod 5 automatically resets and precisely engages with the corresponding limiting groove 6. At the same time, the limiting spring 18 returns to its original length, pushing the sliding plate 17 to reset, causing the positioning rod 20 to automatically engage with the nearest positioning hole 21 under the action of the spring force, thus completing the angle locking.

[0035] The entire adjustment mechanism is located inside the construction site. The precise fit between the end plate 4 and the sliding groove 3 ensures synchronous movement of both sides of the moving plate 2, ultimately forming a continuous, enclosed enclosure structure consisting of the fixed plate 1 and the moving plate 2 connected by the double-sided end plates 4. This achieves rapid adjustment and safe locking functions, and the internal mechanism effectively prevents unauthorized operation by external personnel, ensuring the safety and protection performance of the construction area.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
