Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and in particular relates to a high-level multi-story steel structure corridor and an integral lifting method thereof. Background Art

[0002] In modern mid- to high-rise buildings, structures such as cantilevered corridors are increasingly being used. A corridor connects two high-rise buildings, forming an elevated passageway that serves multiple functions, including personnel passage, firefighting, and sightseeing. Traditional corridor structures often utilize flat steel trusses or hollow trusses. These types of corridors experience uneven loads and often require the use of steel components with larger cross-sections. This results in low internal space utilization and significant material waste. Furthermore, due to the large spans and high-rise locations of these structures, their construction often attracts significant attention, impacting both project quality and progress.

[0003] Common methods for constructing corridor structures include gradual cantilevering and lifting. The gradual cantilevering method involves sequentially installing cantilevered components from the two towers at high altitude, ultimately closing them at mid-span. However, this construction technique involves heavy overhead work, lacks a comprehensive installation platform, and is less safe. Furthermore, the gradual cantilevering method has a long construction period and low efficiency. The lifting method can reduce overhead work, improving efficiency and safety. The overall lifting of a corridor generally involves three steps: on-site assembly on the ground, hydraulic lifting, and high-altitude reinforcement. The traditional lifting method involves lifting each floor of the corridor to the designed configuration, followed by installation and splicing. In recent years, the lifting method has seen widespread application in construction. For multi-story corridors, this method requires repeated operation of the lifting equipment in a sequence, accompanied by multiple lifting and installation operations. For corridors with multiple floors, multiple lifting operations require significant human, material, and financial resources, significantly impacting construction efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a high-level multi-story steel structure corridor and an overall lifting method thereof. Compared with the traditional high-level corridor, the high-level multi-story steel structure corridor structure system designed by the present invention has the characteristics of large bending rigidity, good overall stability, high material utilization rate, and high load-bearing efficiency. Compared with the traditional overall lifting construction method, the present invention can be lifted and installed in one time, greatly reducing the construction workload of multiple lifting of multi-story corridors, with high safety and short construction period. This overall lifting construction method adopts a seat pressure shelving method between the upper and lower corridors, which are in hard contact with each other without welding connection. It does not damage the original corridor, and after the top corridor reaches the designed position, it can very conveniently connect the corridor from top to bottom to its designed position and elevation.

[0005] To achieve the above object, the technical scheme adopted by the present application is as follows:

[0006] A high multi-layer steel structure corridor, comprising N layers of corridors arranged in parallel from bottom to top and fixed between two main towers, wherein 3≤N≤6, characterized in that a vertical joist is arranged in the middle of each of the N layers of corridors;

[0007] When N is odd, vertical support rods are connected below odd-numbered layer joists, hanger columns are connected below even-numbered layer joists, and a pair of inclined cables symmetric about the vertical support rod axis are connected above the even-numbered layer joists, the other end of the inclined cables being connected to odd-numbered layer corridors close to the main towers;

[0008] When N is even, vertical support rods are connected below even-numbered layer joists, hanger columns are connected below odd-numbered layer joists, and a pair of inclined cables symmetric about the vertical support rod axis are connected above the odd-numbered layer joists, the other end of the inclined cables being connected to even-numbered layer corridors close to the main towers.

[0009] The vertical support rods, hanger columns and inclined cables are arranged in two groups, respectively at both ends of the joist.

[0010] A whole lifting method of a high multi-layer steel structure corridor, comprising the following steps:

[0011] Step 1: A pair of lifting beams arranged in parallel are arranged between the two main towers, and N layers of corridors are installed on the lifting beams from bottom to top, wherein 3≤N≤6; two groups of intelligent support jig arrays are hard-connected between every two layers of corridors; a vertical joist is arranged in the middle of each layer of corridors;

[0012] When N is odd, vertical support rods are connected below odd-numbered layer joists, hanger columns are connected below even-numbered layer joists, and a pair of inclined cables symmetric about the vertical support rod axis are connected above the even-numbered layer joists, the other end of the inclined cables being connected to odd-numbered layer corridors close to the main towers; at this time, the vertical support rods do not contact the even-numbered layer joists, the hanger columns do not contact the odd-numbered layer joists, and the inclined cables are in a relaxed state;

[0013] When N is even, vertical support rods are connected below even-numbered layer joists, hanger columns are connected below odd-numbered layer joists, and a pair of inclined cables symmetric about the vertical support rod axis are connected above the odd-numbered layer joists, the other end of the inclined cables being connected to even-numbered layer corridors close to the main towers; at this time, the vertical support rods do not contact the odd-numbered layer joists, the hanger columns do not contact the even-numbered layer joists, and the inclined cables are in a relaxed state;

[0014] Step 2: A sling is installed on the lifting beam, one end of the sling being connected to the lifting beam, the sling being passed through the N layers of corridors without contacting the corridors, the other end of the sling being connected to a hydraulic hoist, and the hydraulic hoist being fixed to the main tower through a pre-buried tension-compression beam;

[0015] Step 3: hoist the sling by the hydraulic hoist, connect the Nth corridor with the main tower when the Nth corridor approaches the design position; then loosen the sling of the remaining N-1 corridors by the hydraulic hoist, reach the design position and connect with the main tower;

[0016] When N is odd, the even-numbered corridor reaches the design position and is connected with the main tower, at this time, the vertical strut is fixedly connected with the even-numbered joist, the hoisting column is fixedly connected with the odd-numbered joist, and the inclined cable is tensioned to reach the preset cable force F1;

[0017] When N is even, the odd-numbered corridor reaches the design position and is connected with the main tower, at this time, the vertical strut is fixedly connected with the odd-numbered joist, the hoisting column is fixedly connected with the even-numbered joist, and the inclined cable is tensioned to reach the preset cable force F1;

[0018] Step 4: after the connection of the Nth corridor is completed, the lintel, sling, hydraulic hoist, displacement monitoring sensor and all intelligent support jigs are removed.

[0019] Before the hoisting of the sling in step 3, the hydraulic hoist is used for trial hoisting to ensure that the corridor is in a horizontal state during hoisting.

[0020] The displacement monitoring sensor is used for monitoring the hoisting displacement and levelness of each corridor, and the intelligent support jig array is used for fine adjustment of the corridor located on the intelligent support jig array until the corridor reaches the design position.

[0021] Each of the two groups of intelligent support jig arrays comprises 2-4 intelligent support jigs distributed at equal intervals, each group of intelligent support jig arrays is installed on the corridor close to the lintel and located between a pair of lintels.

[0022] The corridor is vertically arranged on the two lintels placed in parallel below, and the number of slings connected at equal intervals on each lintel is 4-8.

[0023] The displacement monitoring sensor 11 is installed at a position close to the sling 7 on each corridor.

[0024] Compared with the prior art, the beneficial effects of the present application are:

[0025] (1) The high-position multi-layer steel structure corridor ingeniously utilizes the support system formed by the joist, inclined cable, hoisting column and vertical strut to construct the multi-layer corridor into a stable whole, can effectively reduce the bending moment load of the corridor cross section, thereby reducing the requirement for the cross section size of the corridor steel beam, creating a larger internal use space, and reducing material waste.

[0026] (2) The present invention utilizes supporting beams and inclined cables to improve the overall stiffness, enhance the corridor's ability to resist lateral wind loads, and improve the overall stability of the structure.

[0027] (3) The overall lifting method of the present invention can install and form a multi-story corridor on the ground at one time and complete the lifting at one time, avoiding the work required for frequent setting up of lifting equipment, reducing the repetitive workload of multiple liftings, saving manpower, material resources, financial resources and other resources, further improving construction efficiency and reducing construction costs.

[0028] (4) The present invention utilizes an intelligent support frame to support multiple corridors as a whole, which has good integrity when lifted, and is convenient for installing curtain wall facilities on the corridors and lifting and installing them together; the use of the intelligent support frame facilitates the control of the spacing between the corridors during assembly on the ground according to the designed spacing between the multi-layer corridors, and after lifting, only fine-tuning at high altitude is required to carry out installation and connection, which makes construction convenient and efficient.

[0029] (5) During the lifting process, the lifting force is monitored and controlled in real time by the hydraulic lifter, and the lifting displacement and levelness are monitored and controlled in real time by the displacement monitoring sensor set on the top surface of the corridor. The position and levelness of the corridor during the lifting process can be adjusted very efficiently, and the lifting process is safe and controllable.

[0030] To sum up, compared with the traditional overall lifting construction method, the overall lifting and installation construction method of the high-level multi-story corridor provided by the present invention can lift and install it in one time, greatly reducing the construction workload of multiple lifting of multi-story corridors during high-altitude operations, improving construction safety and shortening the construction period.

DETAILED DESCRIPTION

[0042] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings, taking a high-level three-story steel structure corridor as an example.

[0043] like Figure 1 As shown, a high-rise three-story steel structure corridor includes a first-story corridor 1, a second-story corridor 2, and a third-story corridor 3 fixedly arranged between two main towers 10 and arranged in parallel from bottom to top; a support beam perpendicular to the corridor is provided in the middle of the first-story corridor 1, the second-story corridor 2, and the third-story corridor 3, which are respectively a first support beam 12, a second support beam 13, and a third support beam 14; two hanging columns 17 are vertically provided between the first support beam 12 and the second support beam 13, and are respectively located at the two ends of the first support beam 12 and the second support beam 13; two vertical support rods 16 are vertically provided between the second support beam 13 and the third support beam 14, and are respectively located at the two ends of the second support beam 13 and the third support beam 14; a pair of inclined cables 15 symmetrical about the axis of the vertical support rod 16 are connected to both ends of the second support beam 13, and the other end of the inclined cable 15 is connected to the third-story corridor 3 close to the main tower 10.

[0044] It should be noted that the high-rise multi-story steel structure corridor designed in the present invention includes N-story corridors fixedly arranged between two main towers 10 and arranged in parallel from bottom to top, where 3≤N≤6, and vertical support rods 16 are arranged under the top-floor corridors, and the vertical support rods 16 and the suspension columns 17 are alternately arranged between adjacent corridors; to ensure that the vertical support rods provide a vertical upward force to the top-floor corridor, thereby reducing the vertical deformation of the top-floor corridor.

[0045] like Figures 1-6 As shown, a method for lifting a high-rise three-story steel structure corridor comprises the following steps:

[0046] Step 1: Install a pair of parallel lifting beams 4 between the two main towers 10, install the first-floor corridor 1 on the lifting beams 4, use the lifting beams 4 to support the first-floor corridor 1, and install a first supporting beam 12 parallel to the lifting beams 4 in the middle of the first-floor corridor 1;

[0047] Step 2: Set up two sets of first intelligent support tire frames 5 arrays on the first-floor corridor 1, and install the second-floor corridor 2 on the two sets of first intelligent support tire frames 5 arrays. The first intelligent support tire frames 5 are hard-connected with the second-floor corridor 2, and the first intelligent support tire frames 5 are used to support the second-floor corridor 2; install a second support beam 13 parallel to the lifting beam 4 in the middle of the second-floor corridor 2, and hang a pair of hanging columns 17 at both ends of the second support beam 13, and do not contact the first support beam 12 at first. At this time, both corridors are sitting on the lifting beam 4;

[0048] Step 3: Set up two groups of second intelligent support tire frames 6 arrays on the second-floor corridor 2, install the third-floor corridor 3 on the two groups of second intelligent support tire frames 6 arrays, the second intelligent support tire frames 6 are hard-connected with the third-floor corridor 3, and the third-floor corridor 3 is supported by the second intelligent support tire frames 6; a third support beam 14 parallel to the lifting beam 4 is installed in the middle of the third-floor corridor 3, and a pair of vertical support rods 16 are hung at both ends of the third support beam 14, and do not contact the second support beam 13 at first; a pair of inclined cables 15 are installed at both ends of the second support beam 13, and the other end of the inclined cables 15 is connected to the third-floor corridor 3. At this time, the inclined cables 13 are in a relaxed state, and the three-floor corridors are all sitting on the lifting beam 4;

[0049] Step 4: Install the sling 7 on the lifting beam 4. One end of the sling 7 is connected to the lifting beam 4. The sling 7 is passed through the third-floor corridor without touching the corridor. The other end of the sling 7 is connected to the hydraulic lifter 8. The hydraulic lifter 8 is fixed to the main tower 10 through the pre-buried tension and compression beam 9.

[0050] Step 5: Perform a trial lift using the hydraulic lifter 8 to ensure that the corridor is in a horizontal state during the lifting process;

[0051] Step 6: The sling 7 is formally lifted by the hydraulic lifter 8. When the third-floor corridor 3 approaches the designed position, the displacement and levelness of the third-floor corridor 3 are monitored by the displacement monitoring sensor 11 installed on the top surface of the third-floor corridor 3. The second intelligent support frame 6 array is controlled to fine-tune the levelness of the third-floor corridor 3 until the third-floor corridor 3 reaches the designed position and is connected to the main tower 10.

[0052] Step 7: Loosen the sling 7 through the hydraulic lifter 8 until the second-floor corridor 2 approaches the designed position. The position and levelness of the second-floor corridor 2 are monitored by the displacement monitoring sensor 11 set on the top surface of the second-floor corridor 2. The first intelligent support cradle 5 array is controlled to fine-tune the levelness of the second-floor corridor 2 until the second-floor corridor 2 reaches the designed position, and then the second-floor corridor 2 is connected to the main tower 10. At this time, the vertical support rod 16 is fixedly connected to the second support beam 13, and the diagonal cable 15 is tensioned until the preset cable force value F1 is reached.

[0053] Step 8: Continue to loosen the slings 7 using the hydraulic lifter 8 until the first-floor corridor 1 approaches the designed position. Use the displacement monitoring sensor 11 installed on the top surface of the first-floor corridor 1 to monitor the position and levelness of the first-floor corridor 1. Use the hydraulic lifter 8 and slings 7 to fine-tune the first-floor corridor 1 until the first-floor corridor 1 reaches the designed position. Then, connect the first-floor corridor 1 to the main tower 10. At this time, fix the davits 17 to the first joist 12.

[0054] Step 9: After all the corridors are connected, remove the lifting beams 4, slings 7, hydraulic lifters 8, displacement monitoring sensors 11 and all auxiliary construction facilities such as intelligent support frames.

[0055] The hydraulic lifter 8, displacement monitoring sensor 11, and all intelligent support frames are electrically connected to the control system. The hydraulic lifter 8 uses a built-in pressure sensor to monitor the oil pressure or load force within the hydraulic cylinder in real time, transmitting this signal to the control system for processing. This in turn controls the hydraulic lifter 8 to adjust the lifting force. Similarly, the displacement monitoring sensor 11 monitors the displacement signal in real time and transmits it to the control system for processing. The control system then controls the hydraulic lifter 8 or intelligent support frames to fine-tune the corridor's levelness.

[0056] The deformation pre-adjustment values ​​in the configuration control process of the three corridors are calculated as follows:

[0057] (1) During the lifting stage and before the tensioning of the cable 15, the vertical struts 16, the suspenders 17 and the cable 15 are not subjected to stress; the deformation pre-adjustment values ​​of the three corridor processing stages are set as δ 10 , δ 20 , δ 30 The deformation values ​​of the three corridors under the action of self-weight load are δ 1g, δ 2g , δ 3g During the lifting process, the deformation values ​​of the three corridors are δ 10 +δ 1g , δ 20 +δ 2g , δ 30 +δ 3g ,like Figure 8 As shown, N, F, and T in the figure represent the axial pressure of the vertical strut 16, the tension of the inclined cable 15, and the axial tension of the davit 17, respectively;

[0058] (2) When the tension of the inclined cable 15 is stretched to the preset cable force value F1, the deformation values ​​of the second-floor corridor 2 and the third-floor corridor 3 caused by the inclined cable 15 and the vertical strut 16 are δ 2e1 and δ 3e1 ,like Figure 9 As shown;

[0059] The deformation of the second and third floor corridors 2 and 3 caused by the inclined cables 15 and vertical struts 16 is δ 2e1 and δ 3e1 The solution equation is:

[0060]

[0061] Among them, D2 and D3 are the deformation values ​​of the second-floor corridor 2 and the third-floor corridor 3 caused by the vertical concentrated force of the mid-span unit 1, and EA c is the tensile stiffness of the vertical strut 16, N1 is the axial pressure of the vertical strut 16 after the inclined cable 15 is tensioned, F1 is the preset value of the cable force of the inclined cable 15, and θ is the angle between the inclined cable 15 and the second-floor corridor 2;

[0062] (3) After the construction is finally completed, the deformation of the three-story corridor is δ 10 +δ 1e2 +δ 1g , δ 20 +δ 2e2 +δ 2g , δ 30 +δ 3e2 +δ 3g , where δ 1e2 , δ 2e2 , δ 3e2 are the deformation values ​​of the three-story corridor caused by the inclined cable 15, vertical support rod 16, and suspender 17 in the final state, as shown in Figure 10 As shown, the solution equation is:

[0063]

[0064] Among them, EA sEA is the tensile stiffness of the stay cable 15 d N2 is the axial compression of the vertical support rod 16 after the construction is completed, T1 is the axial tension of the hanging column 17 after the construction is completed, D1 is the deformation value of the first floor corridor 1 caused by the vertical concentrated force of the unit 1 in the span, F2 is the tension of the stay cable 15 after the construction is completed;

[0065] Therefore, according to the final flat state of the three-layer corridor, the deformation pre-adjustment value of the three-layer corridor during processing is determined, that is:

[0066]

[0067] The displacement monitoring sensor 14 is installed at a position close to the sling 7 on each floor corridor. Each group of intelligent support cradle arrays includes 2-4 intelligent support cradles distributed at equal intervals to ensure uniform force distribution of the intelligent support cradle; each group of intelligent support cradle arrays is installed on the corridor close to the lintel 4 and located between a pair of lintels 4.

[0068] The upper and lower ends of the single intelligent support cradle are in hard contact connection with the corridor without welding, so as to avoid structural damage to the main corridor.

[0069] In the high-position multi-layer corridor lifting construction method, 3-6 floor corridors can be lifted at a time; the high-position multi-layer corridor is vertically erected on two parallel placed lifting beams 4 below, and the number of slings connected at equal intervals on each lifting beam 4 is not less than 4, and the number of slings is increased to 8 according to the number of layers and the weight of the lifted corridor.

[0070] The intelligent support cradle used in the application can be a hydraulic adjusting cradle (publication number CN219992191U) or an adjustable support cradle (publication number CN222435974U), which can be raised or lowered within a certain range during construction, adjust the levelness of the corridor during lifting, and will not appear excessive inclination. When the corridor is lifted to the vicinity of the design position, the up and down positions of the corridor are adjusted to facilitate the precise butt joint connection of the closing or post-supplement components.
