Description

Technical Field

[0001] The present invention relates to the technical field of main building structure construction, specifically referring to a stainless steel formwork system for vertical member square columns and its construction method. Background Art

[0002] In the construction industry, formwork is a key tool during the construction process, and its quality and usage method are directly related to the stability of the building structure and construction efficiency. Traditional formwork materials are mostly wood or steel. Wood formwork is light but lacks strength and is prone to deformation, while steel formwork, although having high strength, is heavy, difficult to handle and install, and has a high cost.

[0003] Although the steel-aluminum composite formwork has many advantages, in the actual use process, how to build a stable and reliable support system to ensure the installation and construction quality of the formwork, as well as the assembly, adjustment, fixation, and removal of the formwork, are all challenges that construction workers need to face. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a vertical member square column stainless steel formwork system that is convenient to operate and use, and a construction method thereof that is convenient for construction workers to operate and apply.

[0009] Preferably, in Step 4, the correction includes calibrating the flatness of the plate surfaces around the pouring column root formed by the vertical member and rechecking the elevation;

[0010] It includes vertically lifting the closed column formwork to the designated position, sleeving the positive column steel cage and lowering it to the floor surface, and correcting the verticality and axis position.

[0011] Preferably, in step 4, it also includes using steel wire ropes and wire tighteners on the four sides of the closed column formwork to correct the verticality and fix it.

[0012] Preferably, in step 5, the position correction is to measure the column verticality and axis of the closed column formwork after pouring.

[0013] Preferably, in step 6, first remove the steel wire ropes around, lift and transport the lantern frame, and then remove the vertical components. The removal of the vertical components includes removing them from bottom to top.

[0020] The following further describes the present invention in detail with reference to the drawings.

[0021] Combined with the attached Figures 1-3 As shown, the construction method of the stainless steel formwork for vertical component square columns includes the following steps: Step 1: Prepare the vertical components; Step 2: Arrange, test, and calibrate the preliminary measuring equipment for the working area; Step 3: Coat the vertical components with a release agent; Step 4: Hoist the vertical components, correct the formwork and pour; Step 5: Perform position correction after pouring; Step 6: Remove the stainless steel formwork, clean it, and classify it.

[0022] The vertical component square column stainless steel formwork system includes a measuring module, a hoisting module, a component module and an auxiliary adjustment module, wherein the measuring module includes a total station and a level, the component module includes a vertical component square column, the hoisting module controls the vertical component square column after hoisting and closing, and the auxiliary adjustment module includes a wire rope and a tensioner.

[0023] In the specific implementation of the present invention, the vertical component in step 1 is a stainless steel formwork, and the preliminary measurement equipment includes a total station and a level, and a lantern rack and a construction ladder are built in the working area; the correction includes calibrating the flatness of the plate surface around the casting column root formed by the vertical component and rechecking the elevation;

[0024] Before pouring, the vertical components are evenly coated with release agent, the column steel molds are closed and fastened with bolts, the closed column molds are vertically lifted to the specified position, the column steel cage is put on and lowered to the floor, and the verticality and axis position are corrected.

[0025] At the same time, step 4 also includes using wire ropes and tensioners to correct the verticality and fix the four sides of the closed column mold. The position correction in step 5 is to measure the verticality and axis of the closed column mold after pouring. When dismantling, first remove the surrounding wire ropes, lift the lantern frame, and then remove the vertical components. The dismantling of the vertical components includes dismantling from bottom to top.

[0026] During the specific operation, prepare the total station, level, and infrared and test and calibrate them. Set up the column lantern frame as the construction working surface (including the construction ladder). The inner four sides of the lantern frame are 50cm wide from the KZ side, the spacing between the vertical poles is 1200mm, the spacing between the horizontal poles is 900mm, the step spacing is 1800mm, and the outside is continuously reinforced with scissors struts. Each step is covered with steel mesh, and the facade is fully hung with safety nets. The outer periphery of the top step must have a 1200mm high protective railing. The temporary construction ladder for going up and down is on one side of the lantern frame. The lantern frame is divided into two sections, each weighing about 1.5 tons, and is connected in the middle with channel steel. 20cm steel wire ropes are fixed at the four corners of the two sections of the lantern frame for convenient transfer and recycling of the lantern frame.

[0027] Mark the column axis and positioning line, tie the steel bars in the usual way, do not tie the column cap for now, and mark the structural elevation line on the steel bars at the top of the column, and mark it with dark-colored tape.

[0028] Apply the release agent evenly on the corresponding column formwork, stick the double-sided tape on the contact surfaces of the two pieces of column steel formwork, close the column steel formwork and tighten the bolts. At the same time, when pouring the plate surface around the column root, the flatness and elevation must be strictly poured according to the elevation, the ruler must be accurate, and the elevation must be rechecked after leveling. When installing the column steel formwork, the plate surface around the column is flat, without leakage gaps, and the elevation is absolutely accurate. The axis and elevation must be checked before installation.

[0029] Vertically lift the closed column formwork above the column directly. After verifying the direction, slowly lower the column steel cage with the assistance of 2-3 people, reach the floor surface, and correct the verticality and axis position. Tie the four steel wires and use a wire tightener to correct the verticality and fix it.

[0030] Bind the steel bars of the column cap after pouring. Once again, correct the verticality and axis. Immediately after the column concrete is poured, correct the column verticality again and check the elevation of the column cap and the cooling pad.

[0031] After the concrete begins to set, first remove the steel wires around, lift away the lantern frame, and remove the KZ steel formwork.

[0032] It can be removed only when the strength can ensure that its surface and edges are not damaged due to form removal. The time is different in summer and winter, usually more than 10 hours after pouring. When removing the steel formwork, first remove the bottom short steel formwork, then remove the tie bolts, and then use a jack to horizontally push open the two steel formworks from the lower part of the column and lift out the two steel formworks separately. At the same time, it cannot collide with the column. Before lifting the steel formwork, confirm that the bolts connecting the component and the mold are completely removed before lifting.

[0033] After lifting, immediately clean up the cement slurry nodules emerging from the column root.
