[0046] In an embodiment of the present invention, a connecting head 203 is welded to the end of the tie rod 301, and the end of the connecting head 203 is bolted to a connecting seat 205, a wall-attaching bolt 206 is arranged between one of the connecting seats 205 and the floor plate 101, and the other connecting seat 205 is welded to the tie rod guide seat 204, and the other end of the tie rod guide seat 204 is connected to the floor plate 101 through the wall-attaching bolt 206, and the tie rod 301 is connected to the connecting seat 205 through the connecting head 203, and the two tie rods 301 in the fixed tube are respectively connected to the floor plate 101 and the tie rod guide seat 204 by using the connecting seat 205, and the tie rod guide seat 204 and one of the connecting seats 205 are installed on the floor plate 101 by using the wall-attaching bolt 206.

[0047] In the embodiment of the present invention, a limiting member 300 is arranged between the fixed sleeve 201 and the pull rod 301, and the limiting member 300 includes a control rod 202, a movable rod 302, a spring 303 and a limiting block 304. The movable rod 302 is fixed to the lower end of the pull rod 301, and the control rod 202 is used to control the movement of the movable rod 302. The spring 303 surrounds the outer side of the movable rod 302, and the limiting block 304 is fixed to the bottom end of the movable rod 302. The upper side of the fixed sleeve 201 and one end of the pull rod 301 are provided with a movable hole 305 for the movable rod 302 and the control rod 202 to move. The movable hole 305 is used to enable the movable rod 302 and the control rod 202 to pass through one side of the fixed sleeve 201 and the pull rod 3 01. The lower end of the spring 303 is fixedly connected to the limit block 304, and the upper end of the movable hole 305 is provided with a protrusion block with an L-shaped cross-section.

[0048] In addition, a plurality of movable holes 305 are provided on the surface of the movable rod 302. When the pull rod 301 needs to be adjusted, the limit piece 300 is not installed first. After the pull rod 301 is moved to the required length, the movable control of the control rod 202 is aligned with the movable hole 305 of the fixed sleeve 201, and then the limit piece 300 is inserted. Since the limit block 304 and the spring 303 are both elastic, they can be compressed to pass through the fixed sleeve 201 and the pull rod 301, and the limit block 304 is stuck in the limit hole 306 inside the fixed sleeve 201. When it is needed to be adjusted again later, due to the design of the protruding block, it is necessary to pull out the control rod 202 with force, pull out the limit block 304 and the spring 303, separate the limit piece 300 from the pull rod 301, adjust the position of the pull rod 301, and repeat the above-mentioned operation of installing the limit piece 300, thereby improving the applicability of the adjustable pull rod structure 200.

[0050] Embodiment 2

[0051] See attached Figure 7 As shown, an embodiment of the present invention further provides a construction method of a turnover adjustable web type cantilever support, comprising the following steps:

[0052] Step S1, assembling the frame, proceeding section by section according to the layout diagram of the all-steel attached lifting scaffolding plan and the sequence of the segmented lifting diagram, starting from the end of the frame corner, and installing in sequence;

[0053] Step S2, web plate cantilever support installation, cantilever frame 102 is installed on the floor plate 101 of the bay window, between the cantilever frame 102 and the floor plate 101, a heightening piece, namely, plate support 104 is arranged on the floor behind the bay window, and the plate support 104 is temporarily installed between the cantilever frame 102 and the floor plate 101 by means of vertical rod 105, and the outer end of the cantilever frame 102 is fixed on the frame body of the climbing frame 400 as a temporary reinforcement guide seat, and the attachment unloading is performed, and then the upward wall construction of the bay window is performed, and the adjustable tie rod structure 200 is installed after the construction is completed and reaches the C20 strength, and the adjustable tie rod structure 200 is adaptively adjusted according to the structure of the layer, and then installed to improve the stability, and the plate support 104 is removed after the construction of the layer is completed, and each layer is turned over;

[0054] Step S3, trial operation, after all components of the climbing frame 400 are installed, the project department organizes relevant personnel to conduct a joint acceptance, and after the acceptance is qualified, the climbing frame 400 is hoisted for trial operation;

[0055] Step S4, safety monitoring, sets monitoring points on the frame to monitor the setting and connection of rods, the structure of wall parts and supports, bolt loosening, whether the load is overloaded, and whether the initial value is within a safe range.

[0056] In the embodiment of the present invention, the construction operation of the web-type cantilever support installation in step S2 is as follows:

[0057] Before the construction of the 2nd floor slab 101, an external scaffolding (climbing frame 400 leveling frame) should be set up. After the construction of the 2nd floor slab 101 is completed, the climbing frame 400 will be assembled, and the first assembly will be 6 meters. During the construction of the 3rd floor slab 101, a temporary tie will be made on the 2nd floor slab surface (pre-buried tie points). During the construction of the 4th floor slab 101, the first cantilever support will be installed on the 3rd floor, and the frame will be extended by 2 meters. During the construction of the 5th floor slab, the second cantilever support will be installed on the 4th floor slab, and a temporary tie will be made on the 5th floor slab (pre-buried tie points). During the construction of the 6th floor slab, the third cantilever support will be installed on the 5th floor. After all the third cantilever supports are installed, the scaffolding will be removed. In addition to all temporary connections, the climbing frame 400 needs to be lifted for the first time before the construction of the 7th floor slab. Before lifting, cantilever supports are installed on the 6th floor slab, and the supports on the 3rd floor slab are removed. After all work is completed, the climbing frame 400 is lifted. A final inspection is carried out and all workers within 14 meters of the climbing frame 400 at the bottom of the floor are cleared, and the warning tape is pulled to start lifting the climbing frame 400. After the lifting is completed, the stress state of the lifting wire rope is released, and the stress is borne by the cantilever supports. Before the construction of the 8th floor slab, the climbing frame 400 is lifted for the second time, and cantilever supports are installed on the 7th floor, while the cantilever supports on the 4th floor are removed, ensuring that the frame always has three walls attached, and the cycle is repeated in sequence.

[0058] The specific contents of setting the monitoring points in step S4 are as follows: one monitoring point is set at each corner of the frame, and one monitoring point is set at the top vertical pole 105 at each corner of the frame where the longitudinal and transverse horizontal poles are provided, and one monitoring point is set at the stress point of the cantilever frame 102, and observation is performed relative to the main structure. During the monitoring period, when the deviation exceeds the warning limit or a safety problem is found, it should be monitored in accordance with the project technical person in charge, and monitoring instruments such as theodolites and levels must be used for monitoring, and visual inspection is not allowed. The accuracy of the monitoring instrument should meet the requirements of on-site monitoring, and a deformation monitoring alarm value should be set;

[0059] The monitoring frequency is before the scaffolding is erected, before load is applied on the working layer, after each erection to a height of 6 to 8 meters, after reaching the design height, after encountering extreme weather such as level 5 gale and heavy rain, and after being out of use for more than 1 month.
