Description

Technical Field

[0001] This invention relates to the field of wall-attached structure construction, and in particular to a construction method for a wall-attached structure of a tower crane on a separated single-column cable-stayed bridge tower. Background Technology

[0002] In the construction of separated single-column cable-stayed bridge towers, the tower crane wall-mounted structure is a key component to ensure the safety of tower column construction. In the existing technology, the frame structure mostly adopts rigid bolt connection. The assembly and disassembly process requires repeated tightening or disassembly of a large number of bolts, which is not only time-consuming and labor-intensive, but also prone to low construction efficiency due to limited operating space.

[0003] Meanwhile, the tie rod components of traditional wall-attachment systems lack a real-time stress monitoring mechanism, making it difficult to accurately grasp the load distribution of each tie rod. When the stress on a local tie rod exceeds the limit or its strength is insufficient, it can easily lead to structural deformation or even safety hazards. Existing tension structures cannot dynamically monitor the stress balance according to load changes during the construction phase, making it difficult to guarantee the overall stability of the wall-attachment system. It is also difficult for construction personnel to specifically supplement the parts with abnormal stress, which restricts the safety and efficiency of bridge tower construction.

[0004] Therefore, a construction method is needed that can dynamically monitor the stress on the attached structure based on load changes during the construction phase, allowing construction workers to address any abnormal stress points and improve the safety and efficiency of bridge tower construction. Summary of the Invention

[0005] The main objective of this invention is to provide a construction method for the tower crane wall-attached structure of a split single-column cable-stayed bridge tower, which solves the problem that the tie rod components of traditional wall-attached systems cannot perform real-time monitoring of abnormal stress areas.

Example 2 Further explanation in conjunction with Example 1, such as Figure 1-13 The construction method for the tower crane-attached wall structure of a separated single-column cable-stayed bridge tower, as shown in the figure, is as follows: In step S1, the construction workers begin constructing bridge column 5. At the same time, tower column 6 is constructed simultaneously on one side of bridge column 5, and standard sections of tower column 6 are constructed layer by layer from above tower column 6. In step S2, during the construction of the bridge pier 5, multiple third hinge seats 406 are pre-embedded on the side near the tower pier 6 to prepare for the subsequent connection of the wall-mounted components. After the tower pier 6 is raised to a certain height, the frame 1 is installed. The frame 1 consists of multiple first horizontal bars 101 and second horizontal bars 102, which are arranged vertically and have connectors 103 at their ends. When splicing the frame 1, the ends of the first horizontal bars 101 and second horizontal bars 102 are spliced ​​into the mating grooves 117 of the connectors 103, so that the second insertion hole 116 of the first horizontal bar 101 is aligned with the third insertion hole 118, and the first insertion hole 115 of the second horizontal bar 102 is aligned with the fourth insertion hole 119.

[0029] Next, the first pin 111 and the second pin 112 of the locking piece 105 are inserted into their corresponding holes one by one. The construction worker controls the permanent magnet column 110 to rotate through the knob 109. When the north and south poles of the permanent magnet column 110 are arranged perpendicularly to the copper block 113, a magnetic circuit is formed, causing the first pin 111 and the second pin 112 to attract the first crossbar 101 and the second crossbar 102, preventing them from falling off.

[0030] Repeat the above operation to complete the splicing of frame 1. If it is necessary to disassemble the locking piece 105, control the permanent magnet column 110 to rotate again by the knob 109. When the north and south poles of the permanent magnet column 110 are arranged in the same line as the copper block 113, the copper block 113 will block the magnetic force of the permanent magnet column 110, and the construction personnel can remove the locking piece 105 by the handle 108. Step S3: Install the wall-mounted assembly 4. The wall-mounted assembly 4 includes a main wall-mounted beam 401, with side wall-mounted beams 404 at both ends. A mounting plate 402 is provided on one side of the main wall-mounted beam 401. A second hinge seat 403 on one side of the mounting plate 402 is used to connect to the tie rod assembly 2, and a third hinge seat 406 above it is used to connect to the bridge column 5. During installation, the main wall-mounted beam 401 is first securely connected to the bridge column 5 using high-strength bolts 410. Then, the third end plate 405 on the end face of the side wall-mounted beam 404 is bolted to the embedded plate in the bridge column 5, completing the basic fixing.

[0031] Subsequently, the second tie rod 409 is installed on the third hinge seat 406, and the fourth hinge seat 407 at the other end of the second tie rod 409 is connected to the bridge column 5 by high-strength bolts 410, thus completing the complete fixation of the wall-mounted component 4.

[0032] Step S4: Assemble and connect the traction assembly 3 and the tie rod assembly 2. The tie rod assembly 2 consists of a first tie rod 201 and a second tie rod 202. One end of the first tie rod 201 is provided with a first end plate 205. A rotatable threaded rod 206 on one side of the first end plate 205 is provided with a hinge sleeve 207 at one end.

The traction assembly 3 is arranged between the first side plate 203 and the second side plate 204. The second end plate 208 is rotatably connected to the hinge interface 104 on the frame 1. The hinge interface 104 is provided with a through hinge hole 106. Step S5: Using a crane, install the tie rod assembly 2, which is assembled with the traction assembly 3, between the wall-mounted assembly 4 and the tower column 6. The traction assembly 3 includes a traction main beam 301, with the third side plates 302 at both ends connected to the first side plate 203 and the second side plate 204 by bolts. A traction base plate 303 is provided above the traction main beam 301. A through hole is provided at the center of the rotating base 305 on the traction base plate 303, and a rotatable rotating shaft 309 is located therein. A rotating plate 304 is provided on the top of the rotating shaft 309, and ball bearings are provided between the rotating plate 304 and the rotating base 305 to reduce rotational friction.

[0033] Multiple strain gauges 310 are provided between the circumference of the rotating shaft 309 and the rotating base 305. The strain sensors 311 on the strain gauges 310 are used to detect the rotational torque of the rotating shaft 309. A sleeve 307 is provided in the first hinge seat 306 above the rotating plate 304. A first diagonal tie rod 308 is provided between the sleeve 307 and the bridge tower 5.

[0034] In step S6, throughout the entire construction process, the strain sensors 311 at each level continue to work, feeding back the sensing data to the central control system in real time. The monitoring personnel closely monitor the data in the central control system, and if any abnormality is found in the data of a certain level, they immediately report it to the on-site construction personnel. Based on the feedback information, the on-site construction personnel strengthen the tie rod assembly 2 of the corresponding level, such as increasing the number of tie rods or replacing them with higher strength tie rods, in order to ensure the stability of the tower column 6 during the construction process. Subsequently, after each tower column 6 is raised to a certain height, steps S2-S6 are repeated until the construction of the wall attachment structure is completed.

The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
