Description

Technical Field

[0001] This application relates to the field of cooling tower construction technology, and in particular to a steel walkway structure for cooling tower cylinder wall construction. Background Technology

[0002] Ultra-supercritical coal-fired power generation units are a highly efficient and clean coal-fired power generation technology, characterized by high parameters and high efficiency. Cooling towers are key facilities that provide cooling water circulation for the power generation units. During the early construction of the cooling tower, it is necessary to build an operating platform on the cooling tower that rises with the height of the tower to provide a standing area for construction personnel and a storage area for construction materials.

[0003] The prior art discloses a construction device for formwork flipping of a cooling tower concrete cylinder wall triangular frame and bridge lifting platform, which includes a bridge lifting platform, a lifting mechanism, and multiple sets of formwork units; the formwork unit includes an inner formwork, an outer formwork, and connecting components, with the inner and outer formwork forming an annular pouring cavity; the lifting mechanism includes a platform operating component, a hydraulic lifting component, and two sets of lifting components; the two sets of lifting components are used for lifting the inner and outer formwork respectively; the lifting component includes a lifting ring, multiple hydraulic cylinders, and multiple horizontal adjusting components; multiple hydraulic cylinders are installed on the bridge lifting platform, and the piston rods of the multiple hydraulic cylinders are connected to the lifting ring, with the lifting ring located below the bridge lifting platform; multiple horizontal adjusting components are installed on the lifting ring.

[0004] Regarding the aforementioned technologies, wooden walkway boards are generally used for laying on the bridge platform, and the wooden walkway boards are connected to the template units with steel nails. Over time, the steel nails may loosen, causing the wooden walkway boards to warp, shift, or develop holes, among other risks. Furthermore, the wooden walkway boards also pose a certain fire risk during welding operations. Utility Model Content

[0005] To reduce the possibility of fires during welding and the possibility of walkway panels warping or shifting due to loose steel nails, this application provides a steel walkway panel structure for cooling tower wall construction.

[0006] The steel walkway structure for cooling tower wall construction provided in this application adopts the following technical solution:

[0007] A steel walkway structure for construction of a cooling tower wall includes:

[0008] Steel panel;

[0009] Two reinforcing base plates, which are connected to the steel panel;

[0010] Multiple locking rods are provided, which are connected to the reinforcing base plate and are perpendicular to the steel panel. The plane of the bottom wall of the locking rod is located below the plane of the bottom wall of the reinforcing base plate.

[0011] By adopting the above technical solutions, the designed steel walkway structure for cooling tower wall construction provides a support platform for construction personnel and materials through the steel panels. The steel panels also prevent fires during welding. The reinforced base plate improves the deformation resistance of the steel panels, thereby reducing defects such as warping. The locking rods enable detachable and fixed connections between the reinforced base plate and the lower radial beams or scaffolding structure, such as disassembly and binding, thus preventing the possibility of displacement of the steel panels during use.

[0012] In one specific implementation, the steel panel has multiple water-permeable holes.

[0013] By adopting the above technical solution, the designed permeable holes can first shorten the flow path of rainwater on the top wall of the steel panel, and secondly, the permeable holes can also serve as an anti-slip measure on the steel panel.

[0014] In one specific implementation, the reinforcing base plate is perpendicularly connected to the steel panel, and the reinforcing base plate is connected to the edge of the steel panel.

[0015] By adopting the above technical solution, the reinforced base plate designed to be perpendicularly connected to the edge of the steel panel can be formed by bending the entire steel panel at the edge without welding, thereby reducing the risk of structural failure later.

[0016] In one specific implementation, the spacing between the two reinforcing base plates gradually decreases along the long side of the reinforcing base plates to form a large end and a small end, and the large end of the steel panel overlaps with the small end of the adjacent steel panel.

[0017] By adopting the above technical solution, the designed steel panel with large and small ends and overlapping arrangement can facilitate the connection between two adjacent steel panels and reduce the generation of splicing seams.

[0018] In one specific implementation, at least one plug rod is connected to the bottom wall of the steel panel, and the plug rod can pass through a water-permeable hole opened on an adjacent steel panel.

[0019] By adopting the above technical solution, the designed plug-in rod can achieve positional restriction between two overlapping steel panels.

[0020] In one specific implementation, a plurality of reinforcing vertical ribs are vertically connected to the steel panel, and the reinforcing vertical ribs are connected to the reinforcing base plate.

[0021] By adopting the above technical solutions, the designed reinforcing vertical ribs can further improve the structural strength of the steel panel and reduce the possibility of deformation.

[0022] In one specific implementation, a plurality of carrying rings are movably connected to the steel panel, and the carrying rings can form a through cavity with the steel panel after rotation.

[0023] By adopting the above technical solution, the designed carrying ring facilitates the application of force to the steel panel for handling, installation or disassembly, and the rotatable carrying ring can also reduce interference with the movement of construction personnel.

[0024] In one specific implementation, the top wall of the steel panel is integrally formed with multiple anti-slip patterns.

[0025] By adopting the above technical solutions, the designed anti-slip pattern can increase the friction coefficient of the steel panel top wall and reduce the risk of slipping when construction workers walk on it.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The designed steel walkway structure for the construction of the cooling tower wall provides a support platform for construction personnel and materials. The steel panels also prevent fires during welding. The reinforced base plate improves the deformation resistance of the steel panels, reducing defects such as warping. The locking rods enable detachable and fixed connections between the reinforced base plate and the underlying radial beams or scaffolding structure, such as disassembly and binding, thus preventing the possibility of displacement of the steel panels during use.

[0028] 2. The designed steel walkway structure for the construction of the cooling tower wall, through the water permeable holes, can firstly shorten the flow path of rainwater on the top wall of the steel panel, and secondly, the water permeable holes can also serve as an anti-slip measure on the steel panel.

[0029] 3. The steel walkway structure for the construction of the cooling tower wall is designed with a reinforced base plate that is vertically connected to the edge of the steel panel. The entire steel panel can be bent at the edge without welding, which reduces the risk of structural failure later. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] This application discloses a steel walkway structure for construction of cooling tower walls.

[0038] Reference Figure 1 A steel walkway structure for cooling tower wall construction includes a steel panel 1, a reinforcing base plate 2, and locking rods 3. The top wall of the steel panel 1 is integrally formed with multiple anti-slip patterns 8 to reduce the possibility of slipping when construction workers walk on the steel panel 1. There are two reinforcing base plates 2 connected to the steel panel 1. There are multiple locking rods 3, which are welded and fixed to the reinforcing base plate 2. The locking rods 3 are set perpendicular to the plane of the steel panel 1. The plane of the bottom wall of the locking rod 3 is located below the plane of the bottom wall of the reinforcing base plate 2, so that the locking rod 3 can be inserted into the fixing cylinder fixed on the scaffold to lock the position of the steel panel 1. In this application, the steel panel 1 is preferably a patterned steel plate.

[0039] Reference Figure 2 In order to further improve the anti-slip performance of the steel panel 1, shorten the drainage path of rainwater on the steel panel 1, and reduce the load on the steel panel 1 in rainy weather, a plurality of water-permeable holes 11 are provided on the steel panel 1. In this embodiment, the opening diameter of the water-permeable holes 11 is 22 mm.

[0040] Reference Figure 2 To reduce the number of welding points and the possibility of later failure, the reinforcing base plate 2 is vertically connected to the steel panel 1, and the edges of the reinforcing base plate 2 and the steel panel 1 are integrally connected, that is, the reinforcing base plate 2 is obtained by bending the steel panel 1.

[0041] Reference Figure 3Furthermore, in order to facilitate the application of force to the steel panel 1 for handling, installation or disassembly, multiple carrying rings 7 are movably connected to the steel panel 1. After the carrying rings 7 rotate, they can form a through cavity with the steel panel 1, so that people's hands or lifting tools can pass through the through cavity to grasp. In this application, the carrying rings 7 can be hinged to the steel panel 1 or can be movably connected by a chain, thereby avoiding the carrying rings 7 always being in a perpendicular state to the steel panel 1 and interfering with the walking of construction personnel.

[0042] Reference Figure 4 Specifically, in order to further improve the deformation resistance of the steel panel 1 on the basis of strengthening the base plate 2 and reduce the possibility of warping deformation, multiple reinforcing vertical ribs 5 are vertically welded on the steel panel 1. The reinforcing vertical ribs 5 are welded and fixed to the strengthening base plate 2. In this application, the number of reinforcing vertical ribs 5 can be two, three, or other numbers, as long as it can improve the deformation resistance of the steel panel 1. In this embodiment, the number of reinforcing vertical ribs 5 is two. The two reinforcing vertical ribs 5 can be arranged in parallel or not in parallel.

[0043] Reference Figure 5 Furthermore, the distance between the two reinforcing base plates 2 gradually decreases along the long side of the reinforcing base plate 2, forming a large-head and small-head structure. The large and small heads of the two adjacent steel panels 1 overlap, thereby reducing the gap at the joint of the two adjacent steel panels 1. In addition, in order to achieve position locking after the two adjacent steel panels 1 overlap, at least one plug rod 4 is welded and fixed on the bottom wall of the steel panel 1. The plug rod 4 is set perpendicular to the plane where the steel panel 1 is located, and when the two adjacent steel panels 1 overlap, the plug rod 4 can pass through the water-permeable hole 11 opened on the other adjacent steel panel 1.

[0044] The implementation principle of the steel walkway structure for cooling tower wall construction in this embodiment is as follows: Force is applied to the lifting ring 7 manually or with a hoist to raise the steel panel 1 and move it to the designated installation area above the radial beam. Then, the locking rod 3 engages with the fixing cylinder on the scaffolding. At this time, the locking rod 3 is inserted into the fixing cylinder to lock the position of the steel panel 1. Then, the aforementioned steps are repeated to lay the next steel panel 1. During laying, the large and small ends of adjacent steel panels 1 overlap, and the insertion rod 4 is inserted into the water permeable hole 11 to achieve the positioning between adjacent steel panels 1. The locking mechanism is maintained until all steel panels 1 on the radial beam are installed. The steel panels 1 provide a support platform for construction personnel and materials, and also prevent fires during welding. The reinforced base plate 2 enhances the deformation resistance of the steel panels 1, thereby reducing defects such as warping. The locking rod 3 enables detachable and fixed connections between the reinforced base plate 2 and the underlying radial beam or scaffolding structure, such as disassembly and binding, thus preventing the possibility of displacement of the steel panels 1 during use.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
