Description

Technical Field

[0001] This utility model belongs to the field of pier construction technology, specifically relating to a reusable safety protection device that is easy to disassemble during the clamping method of construction. Background Technology

[0002] The clamping method is a common technique in bridge cap beam construction. The installation and dismantling of clamps require working at heights, posing significant safety risks. Currently, clamp designs on the market do not consider construction safety. In actual construction, workers need to perform high-altitude work. To ensure safety, workers weld several steel pipes along the edge of the constructed platform to enclose the construction area and prevent people or objects from falling. However, this method of welding steel pipes is not only time-consuming and labor-intensive, but also inconvenient to install and dismantle. Furthermore, because it involves welding, dismantling can easily damage the construction platform and steel pipes, hindering their reuse and leading to material waste. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a reusable safety protection device that is easy to disassemble during the construction process of the clamp method, so as to solve the problem that the existing method of setting up a fence on the construction platform is not only time-consuming and labor-intensive, but also the building materials used to build the fence are not easy to reuse.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A reusable safety protection device for easy disassembly during the clamping method of construction includes a primary clamp locked onto a pier. Several steel base plates are circumferentially arranged on the outer surface of the primary clamp. A threaded sleeve is provided on the surface of any one of the steel base plates away from the pier, and the threaded sleeve is fixed to the steel base plate. A railing is provided directly above each threaded sleeve, and a stud is provided at the end of each railing. The stud is fixed to the end of the railing and threadedly connected to the threaded sleeve. Several secondary clamps are fitted onto the outer surface of the railing, and each secondary clamp has at least two lifting rings. Several chains are provided between adjacent railings, with the two ends of each chain hooked onto the lifting rings of the adjacent two railings.

[0006] Furthermore, the railing includes an outer rod and an inner rod, which are threadedly connected.

[0007] Furthermore, each of the steel base plates has an adjustment groove on both sides, the edges of two adjacent steel base plates overlap, and a fixing bolt is provided in the adjustment groove to fix the two adjacent steel base plates together.

[0008] Furthermore, the bottom surface of the steel base plate is provided with a number of longitudinal ribs and transverse ribs in the middle. One end of the transverse rib is flush with the edge of the steel base plate, and the other end of the transverse rib is located near the middle of the steel base plate.

[0009] Furthermore, the longitudinal rib extends to the outer side of the end of the steel base plate at one end facing the primary clamp, and a buckle assembly is provided on the end of the steel base plate facing the primary clamp, the buckle assembly being detachably connected to the primary clamp.

[0010] Furthermore, the part where the primary clamp connects to the buckle assembly is provided with a back rib, and a connecting groove is provided at the end of the back rib, and the buckle assembly is disposed in the connecting groove.

[0011] Furthermore, a pad is provided between the end of the buckle assembly and the pier column.

[0012] Furthermore, the end of the buckle assembly is provided with a locking bolt, which connects the buckle assembly to the primary clamp.

[0024] like Figures 1-5 As shown, a reusable safety protection device for easy disassembly during the clamping method of construction includes a primary clamp 2 locked onto the pier 1. The primary clamp 2 is existing technology, consisting of two semi-circular components fitted onto the pier 1 and then locked with nuts and bolts. Further details are omitted here. Several steel base plates 10 (fan-shaped) are provided around the outer circumference of the primary clamp 2, forming a circular platform 3. The ends of the steel base plates 10 can be welded or detachably connected to the clamp. Any steel base plate 10 can be positioned away from the pier. One end of the 1 is provided with a threaded sleeve 4, which is fixed to the steel base plate 10. A railing 5 is provided directly above the threaded sleeve 4. A stud 9 is provided at the end of the railing 5, which is fixed to the end of the railing 5. The stud 9 is threaded into the threaded sleeve 4. Several secondary clamps 6 are fitted on the outer surface of the railing 5. Each secondary clamp 6 is provided with at least two lifting rings 7. Several chains 8 are provided between two adjacent railings 5. The two ends of the chains 8 are respectively hooked to the lifting rings 7 of the two adjacent railings 5.

[0025] The working principle of the above technical solution is as follows:

[0026] The stud 9 at the end of the railing 5 is threaded into the threaded sleeve 4. Then, by adjusting the relative position of the secondary clamps 6 on the railing 5, the chain 8 can be hooked between adjacent railings 5 ​​to form a circular guardrail, thereby protecting the construction workers on it. At the same time, the setting method makes the overall installation and disassembly of the guardrail simple and reusable.

[0027] In one feasible embodiment, the railing 5 includes an outer bar and an inner bar, which are threaded together to allow the railing 5 to be telescopically adjustable, thereby facilitating the adjustment of the overall height of the railing to adapt to the construction environment.

[0028] In one feasible embodiment, adjustment grooves 14 are provided on both sides of any steel base plate 10. The edges of two adjacent steel base plates 10 overlap, and fixing bolts 13 are provided in the adjustment grooves 14. The fixing bolts 13 fix the two adjacent steel base plates 10 together. The installation of fixing bolts 13 in the adjustment grooves 14 means that the overlapping area between two adjacent steel base plates 10 can be adjusted, thereby changing the area of ​​the circular platform 3 formed by several steel base plates 10. This allows it to be applied to piers 1 of different diameters, and also enables the recycling of steel base plates 10, thus saving building resources.

[0029] In one feasible embodiment, a plurality of longitudinal ribs 11 and transverse ribs 12 are provided in the middle of the bottom surface of the steel base plate 10. One end of the transverse rib 12 is flush with the edge of the steel base plate 10, and the other end of the transverse rib 12 is provided near the middle of the steel base plate 10. The provision of transverse ribs 12 and longitudinal ribs 11 can enhance the load-bearing capacity of the steel base plate 10. At the same time, the advantage of one end of the transverse rib 12 being located in the middle of the steel base plate 10 is that a perforated plate area of ​​a steel base plate 10 without transverse ribs 12 can be placed on the upper surface of another steel base plate 10 with transverse ribs 12, so that there will be no interference problem when adjusting the overlapping area of ​​the two.

[0030] In one feasible embodiment, the longitudinal rib 11 extends to the outer side of the end of the steel base plate 10 at one end facing the primary clamp 2. This end is defined as the extension end 15, and the extension end 15 is provided with a snap-fit ​​assembly 18. The snap-fit ​​assembly 18 is detachably connected to the primary clamp 2. The end of the longitudinal rib 11 is snapped onto the primary clamp 2 by the snap-fit ​​assembly 18, and then the end of the snap-fit ​​assembly 18 is pressed against the pier column 1, thereby limiting the downward movement and deflection of the longitudinal rib 11, thus achieving a fast and stable connection.

[0031] In one feasible embodiment, a back rib 16 is provided at the connection point between the primary clamp 2 and the snap fastener assembly 18. A connecting groove is provided at the end of the back rib 16, and the snap fastener assembly 18 is disposed in the connecting groove. The back rib 16 enhances the load-bearing effect of the primary clamp 2, while the connecting groove facilitates the connection between the snap fastener assembly 18 and the primary clamp 2. It is easy to understand that a fixing post can be set in the connecting groove, and the snap fastener assembly 18 can be a hook. The hook is hung on the fixing post, and the end of the hook contacts the plane of the pier post 1 to achieve a stable connection. Of course, other snap fastener assemblies 18 in the prior art can also be applied to this technical solution as long as they can achieve a stable connection.

[0032] In one feasible embodiment, a pad 17 is provided between the end of the snap-fit ​​assembly 18 and the pier 1. The pad 17 is provided to prevent the end of the snap-fit ​​assembly 18 from causing compression damage to the surface of the pier 1.

[0033] In one feasible embodiment, the end of the snap-fit ​​assembly 18 is provided with a locking bolt 19, which connects the snap-fit ​​assembly 18 to the primary clamp 2. The setting of the locking bolt 19 can further improve the stability of the snap-fit ​​assembly 18 connected to the primary clamp 2. Under the connecting action of the locking bolt 19 (limiting vertical movement) and the abutment action of the end of the snap-fit ​​assembly 18 against the pier column 1 (limiting rotation), the steel base plate 10 can be stably connected to the primary clamp 2.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
