Description

Technical Field

[0001] This utility model relates to the field of template technology, and in particular to a movable, protective, assembled, fixed steel template. Background Technology

[0002] Twisted king blocks are a type of revetment block, commonly used in hydraulic engineering projects such as breakwaters, revetments, sand-blocking dikes, and diversion dikes. They are generally placed on the outermost layer of the dike to protect the dike by weakening the impact of waves. They are made of concrete and are cast in one go using precast templates.

[0003] Existing precast formwork for twisted blocks is generally fixed in one place, and because of its large size, it is not easy to move. Furthermore, when pouring concrete inside the precast formwork for twisted blocks, workers need to vibrate it at the opening on the upper side of the formwork, but the space on the upper side of the formwork is small, making it inconvenient for workers to operate. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a movable, protective, assembled, and standardized steel formwork.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A movable, protective, prefabricated steel formwork includes two identical formwork shells, each of which is provided with:

[0007] A movable part is disposed on the lower side of the template shell and is used to drive the template shell to move.

[0008] The work platform is fixed to the upper side of the template shell, and a protective fence is provided on the outside of the work platform;

[0009] One of the protective fences has a gap, and the work platform has a protective door at the gap.

[0010] Preferably, the template shell includes a lower limb, a middle limb, and an upper limb with an opening at the top. The lower limb, middle limb, and upper limb are interconnected. The two template shells are provided with movable abutting plates, and a fastening bolt is provided between the two abutting plates.

[0011] Preferably, the movable part includes a first support plate fixed at both ends of the lower limb and a second support plate disposed on the side wall of the lower limb. Both the first support plate and the second support plate are provided with rollers with a self-locking structure via supports.

[0012] Preferably, the work platform is equipped with a ladder at the protective door, and a diagonal brace is provided between the ladder and the bottom wall of the work platform.

[0013] Preferably, the protective door includes two door panel structures, each of which includes a sleeve fixed on the working platform, a rotating column rotatably connected in the sleeve, a main door frame connected to the rotating column, a secondary door frame slidably connected to the main door frame, and an elastic element disposed between the main door frame and the secondary door frame. The working platform is provided with a stop bar at the main door frame, and a torsion spring is provided between the rotating column and the sleeve.

[0014] Preferably, a large gear is provided at the bottom of the rotating column, and a small gear is provided at the bottom of the working platform to mesh with the large gear. A winding rod is provided on the small gear to be rotatably connected to the working platform. A drum is provided on the winding rod, and a pull rope is wound and connected to the drum. The end of the pull rope away from the drum is connected to the sub-door frame.

[0015] Preferably, protective netting is provided on the protective fence, the main gate frame, and the secondary gate frame.

[0016] Compared with the prior art, this utility model provides a movable, protective, prefabricated, fixed steel formwork, which has the following advantages:

[0017] 1. This movable, protective, prefabricated steel formwork reduces site occupation and optimizes the space utilization of the prefabrication yard by setting up a movable part; and the working platform, together with the protective fence, ensures the safety of operators.

[0018] 2. This movable, protective, prefabricated steel formwork, by setting the protective door as a double-door structure with two door panels, improves the opening speed and opening angle of the protective door compared to setting only one door panel. Moreover, when the door panel structure opens to the inside of the work platform, the secondary door frame moves and retracts relative to the main door frame, reducing the space occupied by the door panel structure and preventing the door panel structure opening to the inside of the work platform from touching other workers or upper limb shells.

[0019] 3. This movable, protective, prefabricated steel formwork effectively restricts the opening of the protective door to the outside of the work platform by setting a stop bar on the outside of the protective door. This ensures that the workers on the work platform can only open the protective door to the inside of the work platform, thus improving work safety. Attached Figure Description

[0028] like Figures 1 to 3As shown, this embodiment proposes a movable, protective, prefabricated steel formwork, including two identical formwork shells 1. Each formwork shell 1 is provided with a moving part 2 and a working platform 3. The moving part 2 is located on the lower side of the formwork shell 1 and is used to drive the formwork shell 1 to move. The working platform 3 is fixed on the upper side of the formwork shell 1, and a protective fence 4 is provided on the outside of the working platform 3. One of the protective fences 4 is provided with a gap, and a protective door 5 is provided on the working platform 3 at the gap.

[0029] By setting a movable part 2 on the lower side of the template shell 1, it is easy to move the template shell 1, avoid its fixed position, reduce site occupation, and optimize the space utilization of the prefabrication yard; and the working platform 3, together with the protective fence 4, ensures the safety of the operators. The setting of the gap in the protective fence 4 makes it easy for the workers to enter the working platform 3 smoothly from the outside of the protective fence 4. The setting of the protective door 5 prevents the workers from accidentally falling from the gap when working.

[0030] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the template shell 1 further includes a lower limb 101, a middle limb 102, and an upper limb 103 with an opening at the top. The lower limb 101, middle limb 102, and upper limb 103 are interconnected. Two template shells 1 are provided with movable abutting plates 104, and fastening bolts 105 are provided between the two abutting plates 104. A complete force-bearing system is formed by the three-segment interconnected structure of the lower limb 101, middle limb 102, and upper limb 103 with an opening at the top. Each segment adopts a steel box-shaped cross-section design to ensure overall rigidity. The three-segment interconnected structure makes the load transfer more uniform and facilitates the processing and forming of the T-shaped blocks. The top opening design facilitates concrete vibration and rebar binding. Adjustable abutting plates 104 are provided on the mating surfaces of adjacent template shells 1, and quick locking is achieved by high-strength fastening bolts 105.

[0031] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the movable part 2 further includes a first support plate 201 fixed at both ends of the lower limb 101 and a second support plate 202 disposed on the side wall of the lower limb 101. Both the first support plate 201 and the second support plate 202 are provided with rollers 203 with self-locking structures via supports. A split support plate layout is adopted, with the first support plate 201 symmetrically arranged at both ends of the lower limb 101 to bear the main load, and the second support plate 202 forming auxiliary support points through side wall installation, forming a three-point stable load-bearing system. The rollers 203 use polyurethane coated wheel surfaces in conjunction with deep groove ball bearings. The self-locking structure is realized by an electromagnetic brake or a mechanical ratchet mechanism. The self-locking structure is existing technology and will not be described in detail here.

[0032] like Figure 1 and Figure 3As shown, in a preferred embodiment, based on the above method, the work platform 3 is further provided with a ladder 6 at the protective door 5, and a diagonal brace 601 is provided between the ladder 6 and the bottom wall of the work platform 3; the diagonal brace 601 is made of steel pipe, forming a triangular stable structure with the ladder 6 and the bottom wall of the work platform 3, and the connection nodes are fastened with bolts or welded. The installation angle of the diagonal brace 601 is controlled within the range of 45°-60° to ensure that the load is effectively transferred to the main structure of the platform. Workers enter the work platform 3 from the gap by climbing the ladder 6.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the protective door 5 further includes two door panel structures. Each door panel structure includes a sleeve 501 fixed on the working platform 3, a rotating column 502 rotatably connected inside the sleeve 501, a main door frame 503 connected to the rotating column 502, a secondary door frame 504 slidably connected to the main door frame 503, and an elastic element 505 disposed between the main door frame 503 and the secondary door frame 504. The working platform 3 is provided with a stop bar 506 at the main door frame 503, and a torsion spring is provided between the rotating column 502 and the sleeve 501. A double-door panel linkage design is adopted, with the sleeve 501 welded and fixed to the working platform 3, and bearings installed inside to realize the rotation of the rotating column 502. By setting the protective door 5 as a double-opening two-door panel structure, compared with only one door panel, the opening speed and opening angle of the protective door 5 are improved. This design facilitates quick access for workers to the work platform 3, improving work efficiency. A stop bar 506 is installed on the outside of the protective door 5 to restrict its opening outwards from the work platform 3. Workers on the work platform 3 can only open the protective door 5 inwards, making it an inward-opening type, thus improving operational safety. After workers enter the work platform 3, the main door frame 503 is no longer under stress. The torsion spring facilitates the main door frame 503's return to its original position and rotation, while the stop bar 506 limits its movement. During the return to its original position and rotation, the secondary door frame 504 is no longer pulled by the rope 703 and returns to its original position under the push of the elastic element 505. This allows the secondary door frame 504 to cooperate with the main door frame 503 in covering and protecting the gaps in the protective fence 4. It should be noted that the bottom of the main door frame 503 is rotatably connected to the sleeve 501 to ensure the stability of the main door frame 503's rotation.

[0034] like Figure 1 , Figure 3 and Figure 4As shown, in a preferred embodiment, based on the above method, a large gear 5021 is further provided at the bottom of the rotating column 502, and a small gear 7 meshing with the large gear 5021 is provided at the bottom of the work platform 3. A winding rod 701 rotatably connected to the work platform 3 is provided on the small gear 7, and a drum 702 is provided on the winding rod 701. A pull rope 703 is wound and connected to the drum 702, and the end of the pull rope 703 away from the drum 702 is connected to the secondary door frame 504. When the worker opens the door panel structure from the outside to the inside of the work platform 3, the worker pushes the main door frame 5021. 3. The main door frame 503 drives the rotating column 502 to rotate relative to the sleeve 501. The large gear 5021 on the rotating column 502 and the small gear 7 at the bottom of the winding rod 701 rotate. The large gear 5021 rotates half a turn and the small gear 7 rotates multiple turns. The large transmission ratio makes the winding rod 701 wind up the pull rope 703 through the drum 702. The pull rope 703 applies a pulling force to the secondary door frame 504, causing the secondary door frame 504 to move and retract towards the main door frame 503, reducing the space occupied by the entire door panel structure and preventing the door panel structure that opens to the inside of the work platform 3 from touching other workers or the upper limb 103 shell.

[0035] like Figure 1 As shown, in a preferred embodiment, based on the above method, protective nets are further provided on the protective fence 4, the main gate frame 503 and the secondary gate frame 504; the protective nets are made of square-hole steel wire mesh (not shown in the figure). The steel wire mesh is not a prior art and can be connected to the fence frame by welding or bolt fixing, which further improves the safety of workers.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
