[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0041] The embodiment of the present application provides a concrete tower construction platform and an installation method thereof, which can solve the problem that during the installation of the construction platform, the components of the bracket cannot be adjusted when laying the panel, thereby affecting the stability of the bracket.

[0042] like Figure 1 As shown, a concrete tower construction platform includes a bracket 1 and a panel 5.

[0043] The bracket 1 includes a bracket 11 and a distribution beam 12. The end of the bracket 11 is used to connect with the tower column 2. The distribution beam 12 is placed on the top surface of the bracket 11. The panel 5 is laid on the top surface of the distribution beam 12, and the panel 5 is abutted against the tower column 2. The panel 5 is provided with mounting holes penetrating the panel surface, and each mounting hole is provided with an openable cover plate 6.

[0044] Specifically, the above-mentioned concrete tower column construction platform may include one construction platform or multiple construction platforms, each of which includes a bracket 1 and a panel 5. Different construction platforms can be set on different side walls of the tower column 2. The number of brackets 1 in each construction platform 1 can be set according to actual conditions.

[0045] Specifically, the brackets 1 of the same construction platform are arranged side by side, that is, the top surfaces of the brackets 11 of the brackets 1 of the same construction platform are located at the same horizontal plane, ensuring the stability of the panel 5 above the brackets 11. In addition, there is a distance between each two adjacent brackets 11. Preferably, the distance between each two adjacent brackets 11 is equal, so that each bracket 11 can be evenly stressed, and the panel 5 can be balanced, thereby enhancing the bearing capacity and overall structural stability of the bracket 1. The number of brackets 11 of each bracket 1 can be determined according to actual conditions.

[0046] Specifically, the number of distribution beams 12 of each bracket 1 can also be determined according to actual conditions. In the embodiment of the present application, the distribution beam 12 of each bracket 1 is perpendicular to the corbel 11, and the distribution beams 12 are evenly placed on the top surface of the corbel 11 of the bracket 1, and the distance between each two adjacent distribution beams 12 is equal, so that the distribution beam 12 can evenly transfer the load of the panel 5 to the corbel 11 below to avoid concentrated loads or eccentric loads that affect the overall structural stability of the bracket 1. In other embodiments, the distribution beam 12 can also have an inclined angle relative to the corbel 11. Optionally, the above-mentioned distribution beam 12 can be made of I-10 steel.

[0047] Furthermore, the mounting hole is located above the intersection of the distribution beam 12 and the corbel 11 , and one side of each cover plate 6 is hinged to the panel 5 via a hinge 9 .

[0048] Specifically, in the embodiment of the present application, each mounting hole of the panel 5 is a square hole, and the mounting hole has four hole walls, one of which is provided with a hinge 9. The cover plate 6 is also a square plate-shaped structure, and the size of the cover plate 6 is the same as the size of the mounting hole. When the cover plate 6 covers the mounting hole, the top surface of the cover plate 6 is flush with the top surface of the panel 5, ensuring the flatness of the top surface of the panel 5. In other embodiments, the shape of the mounting hole can be determined according to actual conditions, and the shape and size of the cover plate 6 are the same as the mounting hole. Optionally, the above-mentioned cover plate 6 can adopt a 6mm thick patterned steel plate.

[0049] Specifically, in the embodiment of the present application, the number of mounting holes is multiple rows, and each row of mounting holes is arranged along the extension direction of the distribution beam 12, and the mounting holes are located above the intersection of the distribution beam 12 and the corbel 11, that is, the cover plate 6 is located above the intersection of the distribution beam 12 and the corbel 11. The position of the mounting holes is a weak force area of ​​the panel 5. When the cover plate 6 is subjected to a downward load, the distribution beam 12 and the corbel 11 can give the cover plate 6 an upward support force. The distribution beam 12 and the corbel 11 play a role in strengthening the structure at the mounting holes, ensuring the overall bearing capacity of the panel 5. Preferably, each row of mounting holes is evenly arranged to ensure that the panel 5 is subjected to a balanced force.

[0050] Specifically, in the embodiment of the present application, the side wall of the tower column 2 is irregularly shaped, and there is a distance between the inner edge of each panel 5 and the side wall of the tower column 2. A cover plate 6 is provided within the distance, and one side of the cover plate 6 is hinged to the inner edge of the panel 5 through a hinge 9, and the other side of the cover plate 6 is against the side wall of the tower column 2. A cover plate 6 with the same shape as the chamfer is also provided at the chamfer. When installing and disassembling the concrete tower column construction platform of the embodiment of the present application, the cover plate 6 can be opened to facilitate the installation and disassembly of the bracket 1 and the tower column 2 at high altitude, thereby improving the construction efficiency. Optionally, the above-mentioned cover plate 6 can adopt a 6mm thick patterned steel plate.

[0051] Further, such as Figures 5 to 10 As shown, the tower column 2 is provided with a fixing member 3, and the end of the corbel 11 is provided with a connecting plate 7 for connecting with the fixing member 3, one end of the fixing member 3 is connected to the tower column 2, and the other end is detachably connected to the connecting plate 7.

[0052] Specifically, in the embodiment of the present application, each corbel 11 includes a crossbar 111 and a diagonal brace 112, the end of the crossbar 111 is used to connect with the tower column 2, and the distribution beam 12 is placed on the top surface of the crossbar 111. The above-mentioned connecting plate 7 is vertically arranged, which is perpendicular to the corbel 11. Specifically, the connecting plate 7 is perpendicular to the crossbar 111 of the corbel 11. When constructing the tower column 2, the fixing member 3 is pre-buried, one end of the fixing member 3 is buried in the interior of the tower column 2, and the other end passes through the connecting plate 7 and is detachably connected to the connecting plate 7. When the bracket 1 needs to be removed, it is only necessary to separate the fixing member 3 from the connecting plate 7 to separate the corbel 11 from the tower column 2. The structure is simple, easy to install and disassemble, and can improve the installation efficiency. The above-mentioned fixing member 3 can be a climbing cone, and the crossbar 111 of each corbel 11 is connected to the tower column 2 through two climbing cones. The connecting plate 7 has two through holes, and the two climbing cones pass through the through holes of the connecting plate 7 and are fixed by bolts. In other embodiments, the number of climbing cones can be determined according to actual conditions.

[0053] Furthermore, a stiffening plate 8 is provided at the connection between the connecting plate 7 and the corbel 11 , and a part of the stiffening plate 8 is connected to the connecting plate 7 , and a part of the stiffening plate 8 is connected to the corbel 11 .

[0054] Specifically, the stiffening plates 8 play a role in strengthening the corbels 11. Each corbel 11 includes a crossbar 111 and a diagonal brace 112. The end of the crossbar 111 is used to connect with the tower column 2, and the distribution beam 12 is placed on the top surface of the crossbar 111. In the embodiment of the present application, the number of stiffening plates 8 is three, and the three stiffening plates 8 form a gate-shaped structure. The gate-shaped structure is arranged across the top surface of the crossbar 111 of the corbel 11. The stiffening plates 8 are fixedly connected to the crossbar of the corbel 11 and are fixedly connected to the connecting plate 7.

[0055] Further, such as Figure 5 , Figures 11 to 12 As shown, each corbel 11 includes a cross bar 111 and a diagonal brace 112. The end of the cross bar 111 is used to connect with the tower column 2. The distribution beam 12 is placed on the top surface of the cross bar 111. One end of the diagonal brace 112 is connected to the cross bar 111, and the other end is provided with a supporting plate 4 for being attached and fixed to the tower column 2.

[0056] Specifically, in the embodiment of the present application, the crossbar 111 of each corbel 11 is horizontally arranged, and one end of the crossbar 111 is used to connect with the tower column 2, and the diagonal brace 112 of each corbel 11 plays a role in strengthening the crossbar 111. The crossbar 111, the diagonal brace 112 of the corbel 11 and the side wall of the tower column 2 form a triangular structure, which ensures the stability of the corbel 11. In the embodiment of the present application, a vertical stiffening rod 113 is also arranged between each crossbar 111 and the diagonal brace 112, one end of the stiffening rod 113 is connected to the crossbar 111, and the other end is connected to the diagonal brace 112, which is conducive to enhancing the structural stability and bearing capacity of the corbel 11. Optionally, the crossbar 111, the diagonal brace 112 and the stiffening rod 113 of the above-mentioned corbel 11 are all double-jointed channel steel structures.

[0057] Specifically, a support plate 4 is provided at the end of the diagonal brace 112, and the support plate 4 is closely fitted with the side wall of the tower column 2, which can reduce the use of the fixing member 3, thereby reducing the embedded components inside the tower column 2, so as to avoid adverse effects on the structure of the tower column 2. In addition, when the support plate 4 is fitted with the side wall of the tower column 2, the crossbar 111 of the corbel 11 is in a horizontal state.

[0058] Furthermore, Figures 2 to 4 As shown, the concrete tower column construction platform of the embodiment of the present application includes a first construction platform, a second construction platform and a third construction platform. The first construction platform and the third construction platform are located at opposite ends of the second construction platform and are perpendicular to the second construction platform. The first construction platform, the second construction platform and the third construction platform all include a bracket 1 and a panel 5. The distribution beam 12 of the first construction platform and the distribution beam 12 of the third construction platform are respectively set up at opposite ends of the second construction platform.

[0059] Specifically, in the embodiment of the present application, the concrete tower column construction platform of the embodiment of the present application includes a first construction platform, a second construction platform and a third construction platform, and the number of panels 5 is three. The three panels are laid on the top surfaces of the brackets of the three construction platforms respectively, and each panel 5 is against different side walls of the tower column 2 to ensure a tight connection with the side wall of the tower column 2 to avoid accidents of falling from a high altitude. Each panel 5 is provided with a mounting hole, and the number of mounting holes provided on each panel 5 can be determined according to actual conditions. Preferably, the mounting holes on each panel 5 are evenly arranged to ensure that the panel 5 is evenly stressed.

[0060] Specifically, in the embodiment of the present application, the first construction platform, the second construction platform and the third construction platform are surrounded by the three side walls of the tower column 2, and construction workers can walk freely on the panels 5 of the first construction platform, the second construction platform and the third construction platform to ensure sufficient construction space.

[0061] Specifically, in the embodiment of the present application, both ends of the distribution beam 12 of the second construction platform extend out of the side wall of the tower column 2, the distribution beam 12 of the first construction platform extends out of the side wall of the tower column 2 adjacent to the end of the second construction platform, and the distribution beam 12 of the third construction platform extends out of the side wall of the tower column 2 adjacent to the end of the second construction platform. The portion of the distribution beam 12 of the first construction platform extending out of the side wall and the portion of the distribution beam 12 of the third construction platform extending out of the side wall are both arranged at the opposite ends of the distribution beam 12 of the second construction platform extending out of the side wall, so as to ensure the structural stability of the junction of the first construction platform, the second construction platform and the third construction platform. In the embodiment of the present application, the distribution beams 12 of the first construction platform, the second construction platform and the third construction platform are exactly the same, the positions of the corbels 11 of the first construction platform and the third construction platform are higher than the position of the corbels 11 of the second construction platform, and the height difference is exactly the height of the distribution beam 12. When the distribution beams 12 of the first construction platform, the second construction platform and the third construction platform are different, the height difference between the position of the corbel 11 of the first construction platform and the position of the corbel 11 of the second construction platform is the height of the distribution beam 12 of the first construction platform, and the height difference between the position of the corbel 11 of the third construction platform and the position of the corbel 11 of the second construction platform is the height of the distribution beam 12 of the third construction platform.

[0062] In the embodiment of the present application, the first construction platform is adjacent to the elevator 16 , and the third construction platform is adjacent to the tower beam 15 . It can be known that the first construction platform should avoid the position of the elevator 16 , and the third construction platform should avoid the position of the tower beam 15 .

[0063] Furthermore, the support 1 includes a plurality of corbels 11 arranged side by side, and a column 10 is provided at the end of each corbel 11 away from the tower column 2. The plurality of columns 10 are connected by horizontal rods 13 to form a fence.

In the embodiment of the present application,

[0065] Specifically, in the embodiment of the present application, a skirting board 14 is also provided at the bottom of the fence. The skirting board 14 is a vertically provided board. The skirting board 14 is simultaneously connected to a plurality of columns 10. The skirting board 14 can prevent the construction materials and tools on the panel 5 from falling from a high altitude, thereby ensuring the safety of the construction. The height of the skirting board 14 can be determined according to the actual situation. In the embodiment of the present application, the height of the skirting board 14 is 25 cm, and a 6 mm thick patterned steel plate can be used. The columns 10 and the horizontal rods 13 of the fence can both use a 48 mm diameter construction steel pipe.

[0066] The embodiment of the present application also includes a construction method based on the above concrete tower column construction platform, which includes the following steps:

[0067] Step 1: Fix the end of the bracket 11 of the bracket 1 to the tower column 2.

[0071] Specifically, in the above step 2, the panel 5 and the distribution beam 12 are pre-installed as a whole on the ground, and then the whole is hoisted. Only the distribution beam 12 needs to be welded at high altitude, which reduces the difficulty and process of high-altitude operations and ensures the safety of the installation process. In addition, pre-installing the panel 5 on the ground can improve the installation efficiency.

[0072] Specifically, in the above step 3, the distribution beam 12 and the corbel 11 can be welded through the mounting hole. After the welding is completed, the cover plate 6 can be covered, which is simple to operate.

[0073] Specifically, in the above steps 1 and 2, the end of the bracket 11 of the bracket 1 can be first fixed to the tower column 2, and then the panel 5 and the distribution beam 12 of the bracket 1 are installed as a whole, and the panel 5 and the distribution beam 12 are hoisted to the preset installation position, so that the distribution beam 12 is placed on the top surface of the bracket 11. The panel 5 and the distribution beam 12 of the bracket 1 can also be installed as a whole first, and then the end of the bracket 11 of the bracket 1 is fixed to the tower column 2, and the panel 5 and the distribution beam 12 are hoisted to the preset installation position, so that the distribution beam 12 is placed on the top surface of the bracket 11. It is also possible to fix the end of the bracket 11 of the bracket 1 to the tower column 2 and install the panel 5 and the distribution beam 12 of the bracket 1 as a whole at the same time, and then hoist the panel 5 and the distribution beam 12 to the preset installation position, so that the distribution beam 12 is placed on the top surface of the bracket 11.

[0074] Furthermore, the above concrete tower column construction platform includes a first construction platform, a second construction platform and a third construction platform, and the above construction method includes:

[0075] The ends of the corbels 11 of the first platform, the second platform and the third platform are fixed to the three side walls of the tower column 2 respectively, so that the corbels 11 of the first platform and the third platform are higher than the corbels 11 of the second platform.

[0076] The panels 5 of the first construction platform, the second construction platform and the third construction platform are laid on the top surfaces of the corresponding distribution beams 12 respectively, and the panels 5 and the distribution beams 12 of the first construction platform, the second construction platform and the third construction platform are hoisted to the top surfaces of the corresponding corbels 11, so that the distribution beams 12 of the first construction platform and the third construction platform are erected on the top surface of the distribution beam 12 of the second construction platform.

[0077] The cover plates 6 of the first construction platform, the second construction platform and the third construction platform are opened, and the distribution beam 12 under the panel 5 is welded to the corbel 11 to form a concrete tower column construction platform.

[0078] Specifically, in the above steps, both ends of the distribution beam 12 of the second construction platform extend out of the side walls of the tower column 2, the distribution beam 12 of the first construction platform extends out of the side wall of the tower column 2 at the end adjacent to the second construction platform, and the distribution beam 12 of the third construction platform extends out of the side wall of the tower column 2 at the end adjacent to the second construction platform. The portion of the distribution beam 12 of the first construction platform extending out of the side wall and the portion of the distribution beam 12 of the third construction platform extending out of the side wall are arranged at the opposite ends of the distribution beam 12 of the second construction platform extending out of the side wall, thereby ensuring the structural stability of the junction of the first construction platform, the second construction platform and the third construction platform.

[0079] Specifically, in the above steps, the distribution beams 12 of the first construction platform, the second construction platform and the third construction platform are exactly the same, the positions of the corbels 11 of the first construction platform and the third construction platform are higher than the position of the corbel 11 of the second construction platform, and the height difference is exactly the height of the distribution beam 12. When the distribution beams 12 of the first construction platform, the second construction platform and the third construction platform are different, the height difference between the position of the corbel 11 of the first construction platform and the position of the corbel 11 of the second construction platform is the height of the distribution beam 12 of the first construction platform, and the height difference between the position of the corbel 11 of the third construction platform and the position of the corbel 11 of the second construction platform is the height of the distribution beam 12 of the third construction platform.

[0080] Furthermore, each corbel 11 includes a crossbar 111 and a diagonal brace 112, and a supporting plate 4 is provided at the end of the diagonal brace 112. The above step 1 includes:

[0081] The end of the cross bar 111 is fixedly connected to the tower column 2, and the support plate 4 at the end of the diagonal brace 112 is attached to the tower column 2, so that the support plate 4 is fixedly connected to the tower column 2. The support plate 4 is completely fitted with the side wall of the tower column 2, and the cross bar 111 is ensured to be in a horizontal state.
