[0002] Formwork columns are a new type of building component. They adopt standardized design and modular production methods. After the prefabricated manufacturer conducts secondary deepening of the formwork columns according to the design drawings, they are centralized, streamlined, and industrialized in the prefabricated component factory. The construction process of formwork columns is as follows: first prefabricate the formwork columns, embed the vertical connecting steel bars of the foundation formwork columns (no need to embed the next layer or embed the next layer of columns after the diameter is changed), embed the retractable inclined support fixing bolts of the formwork columns on the floor slabs or beams in all directions perpendicular to the plane of the formwork column body, and after the concrete is poured, the prefabricated formwork columns are installed; when installing the formwork columns, the retractable inclined support adjustment rod is used to adjust the vertical verticality and axis displacement deviation of the formwork columns.

[0036] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0037] like Figure 1 to Figure 4 As shown, a fixed bracket for oblique support connection of membrane shell columns in this embodiment includes multiple straight chassis beams, which are vertically fixed and connected head to tail in sequence to form a rectangular frame, and an inverted U-shaped ring 4 is provided in the middle position of the upper surface of each side of the rectangular frame, and the perforation direction of the inverted U-shaped ring 4 is arranged perpendicular to one side of the rectangular frame in which it is located.

[0038] like Figure 1 and Figure 5As shown, in this embodiment, there are four straight chassis beams, one straight chassis beam is provided on each side of the rectangular frame, and two adjacent straight chassis beams are vertically fixedly connected. Four straight chassis beams are used to conveniently connect and form a rectangular fixed bracket.

[0039] like Figure 1 As shown, the four straight chassis beams of this embodiment include two first chassis beams 1 and two second chassis beams 2. The two first chassis beams 1 are arranged in parallel and opposite to each other, and the two second chassis beams 2 are arranged in parallel and opposite to each other; the two ends of one first chassis beam 1 are respectively vertically fixedly connected to one end of the two second chassis beams 2, and the two ends of the other first chassis beam 1 are respectively vertically fixedly connected to the other end of the two second chassis beams 2.

[0040] like Figure 1 As shown, the end faces of each of the first chassis beams 1 of this embodiment are respectively vertically fixedly connected to the end side faces of the two second chassis beams 2, and the two first chassis beams 1 are fixed between the two second chassis beams 2. The formed rectangular frame structure is regular and has better structural stability.

[0041] like Figure 1 to Figure 4 As shown, the first chassis beam 1 and the second chassis beam 2 of this embodiment are both U-shaped channel steel structures, and both ends of the U-shaped channel steel structure are sealed with a blocking steel plate 3 for sealing the two ends of the opening; the blocking steel plate 3 at the end of the first chassis beam 1 abuts against the side of the end of the second chassis beam 2 and is connected and fixed by a connecting piece. By providing the blocking steel plate, it is convenient to stably connect the first chassis beam and the second chassis beam.

[0042] like Figure 1 and Figure 4 As shown, the connecting member of this embodiment includes a connecting bolt 5 and a connecting nut 6. The connecting bolt 5 passes through the correspondingly arranged end sealing steel plate 3 of the first chassis beam 1 and the side of the end of the second chassis beam 2, and is locked and fixed by the connecting nut 6.

[0043] like Figure 7 to Figure 9 As shown, the two ends of the inverted U-shaped ring 4 of this embodiment are bent outward to form legs 41, and the legs 41 are welded and fixed to the upper surface of the linear chassis beam. The inverted U-shaped ring is conveniently welded and fixed to the linear chassis beam by providing the legs.

[0044] Specifically, Fig.12 As shown, another optional solution of this embodiment is that a connecting rod 42 is provided in the middle position of the inverted U-shaped ring 4, and both ends of the connecting rod 42 are fixedly connected to the middle positions of the two supporting rods of the inverted U-shaped ring 4 respectively.

[0045] After the construction of the fixed bracket of this embodiment is completed, the removal work can be completed by simply unscrewing the inclined support and the fixed bracket bolts embedded in the side of the membrane shell column. The fixed bracket can be reused many times, which greatly reduces the cost and construction efficiency.

[0046] like Figures 5 to 11 As shown, the present embodiment also provides a membrane shell column, comprising the above-mentioned fixed bracket for connecting the membrane shell column oblique support, and also comprising an oblique support 7 and a membrane shell column body 8, wherein the membrane shell column body 8 is arranged vertically, and the rectangular frame is sleeved on the outside of the bottom of the membrane shell column body 8, and the four sides of the rectangular frame correspond to the four side surfaces of the membrane shell column body 8 one by one and are arranged in parallel; a fixing ring is pre-embedded on each side surface of the membrane shell column body 8, and the fixing ring and the inverted U-shaped ring 4 located on the same side of the membrane shell column body 8 are connected by an oblique support.

[0047] A preferred solution of this embodiment is that the oblique support 7 is a telescopic structure. By adopting an oblique support with a telescopic structure, it is convenient to adjust the support length as needed. Specifically, the oblique support 7 includes a telescopic screw 71 and a screw sleeve 72. A screw sleeve 72 is connected to the fixed ring embedded on the outer wall of the membrane shell column body 8, and a screw sleeve 72 is also connected to the inverted U-shaped ring 4 on the fixed bracket. The two ends of the telescopic screw 71 are respectively threadedly connected to the two screw sleeves 72. The telescopic screw 71 can be screwed as needed to extend into the screw sleeve 72 or extend from the screw sleeve 72, thereby adjusting the length of the oblique support 7.

[0048] like Figure 6 As shown, an optional scheme for the membrane shell column of this embodiment is that there are two fixed brackets, namely a first fixed bracket and a second fixed bracket, the side length of the rectangular frame formed by the first fixed bracket is greater than the side length of the rectangular frame formed by the second fixed bracket, and the first fixed bracket is arranged at intervals on the outside of the second fixed bracket; two fixing rings arranged at intervals up and down are pre-embedded on each side of the membrane shell column body 8, and the two fixing rings are respectively a first fixing ring 81 and a second fixing ring 82, and the first fixing ring 81 is arranged at intervals above the second fixing ring 82, and the first fixing ring 81 is connected to the inverted U-shaped ring 4 on the first fixing bracket through a first oblique support, and the second fixing ring 82 is connected to the inverted U-shaped ring 4 on the second fixing bracket through a second oblique support. The membrane shell column can be effectively supported by using two fixed brackets. The length of the first oblique support is greater than the length of the second oblique support.

[0049] like Figure 10 to Figure 12As shown, another optional scheme for the membrane shell column of this embodiment is that there is one fixed bracket; two fixing rings arranged at intervals up and down are pre-embedded on each side of the membrane shell column body 8, and the two fixing rings are respectively a first fixing ring 81 and a second fixing ring 82, and the first fixing ring 81 is arranged at intervals above the second fixing ring 82, the first fixing ring 81 is connected to the inverted U-shaped ring 4 on the fixed bracket through a first oblique support, and the second fixing ring 82 is connected to the connecting rod 42 on the inverted U-shaped ring 4 on the fixed bracket through a second oblique support.

[0050] The membrane shell column of this embodiment is designed in depth in the early stage, and the construction position of the mold shell column is located by measuring and laying out in the later stage. When the mold shell column is installed, the mold shell column fixing bracket is assembled at the position of the mold shell column, and the retractable diagonal support is connected by welding an inverted U-shaped ring on the top of the bracket, thereby completing the adjustment of the vertical verticality and axis displacement deviation of the mold shell column and fixing the mold shell column. The vertical diagonal support of the mold shell column is two on each side of the column body plane. The retractable diagonal support is made of a steel grade not lower than Q235. At the same time, in order to prevent the possibility of rusting of the steel retractable diagonal support during use, the steel is treated with galvanizing process to prevent rust.

[0051] The fixed bracket of this embodiment is made of a channel steel with a grade not less than Q235. Sealing steel plates are set at both ends of the channel steel and holes are opened for the connection bolts to pass through. There is a welded round steel inverted U-shaped ring with a grade not less than Q235 on the top of the channel steel, which has great strength and good pressure bearing capacity. The inclined support fixed bracket is composed of three parts, namely U-shaped channel steel structure + connector + inverted U-shaped ring, thereby avoiding the displacement of the embedded threaded steel bars or round steel as the membrane shell column oblique support during the concrete pouring process, resulting in inaccurate embedded position, and the cost of secondary rework and drilling holes to add expansion bolts. At the same time, after the retractable oblique support is removed, a large amount of cost needs to be invested again, and various costs for cutting off the embedded threaded steel bars or round steel are required. This embodiment only needs to purchase the required raw materials according to the design drawings, use a cutting machine to process the channel steel into the required size, use a machine to perform secondary drilling of the channel steel and weld the inverted U-shaped ring according to the oblique support position of the mold shell column, and can also be processed and manufactured by the manufacturer. After the production is completed, the on-site operators are arranged to place the formwork column fixing bracket on the floor slab where the formwork column is installed when installing the formwork column. After the formwork column is adjusted to the installation position and the vertical steel bars of the membrane shell column are connected, the formwork column is fixed to the fixing bracket by using the retractable diagonal support to prevent the formwork column from producing displacement deviation during the subsequent concrete pouring process. At the same time, the fixed number of retractable diagonal supports can be added according to actual needs to ensure that the formwork column is firmly fixed. After the construction of the formwork column is completed, a wrench is used to unscrew the bolts of the fixing bracket and the retractable diagonal support bolts to complete the disassembly of the fixing bracket and the diagonal support. When used next time, reinstall and fix according to the above steps. This embodiment fundamentally and greatly reduces the construction cost of the membrane shell column.

[0052] The membrane shell column of this embodiment is provided with a fixed bracket. During the main construction stage of the building, the inclined support and fixed bracket of the formwork column are customized or manufactured according to the detailed drawings of the formwork column and the structural positioning. When the formwork column is installed, the fixed bracket is placed on the structural floor slab, and the inclined support is installed at the same time, and the fixed support of the formwork column is realized by using the opposite pulling force. The membrane shell column of this embodiment effectively reduces the huge cost of the formwork column construction due to the pre-embedded threaded steel bars or round steel as the position fixation of the formwork column, and changes the construction operation mode, improves the construction technology, and can be reused, which truly achieves the purpose of reducing costs and increasing efficiency and promoting technological development.
