Description

Technical Field

[0001] The invention relates to a hydraulic climbing formwork construction platform adaptable to variable cross-sections of buildings and a construction method thereof. Background Art

[0002] The construction of high-rise buildings (structures) and giant concrete outer frame columns requires a large amount of material storage space. However, due to the limited space of the frame, traditional hydraulic climbing formwork can only store a portion of the materials and cannot integrate construction machinery such as concrete placing machines. In addition, to balance the structural weight and wind-exposed area of ​​high and low-lying areas and improve the overall stability of the building, high-rise buildings (structures) will have multiple cross-section indentations as the building (structure) increases in height. The indentation spacing generally varies from 100mm, 200mm, and 300mm. To address this type of building (structure) cross-section variation, the traditional hydraulic climbing formwork construction method is as follows:

[0003] Step 1: The cross section of the Nth structure construction section is indented inward by 100mm, and the hydraulic climbing formwork is attached to the N-1th structure construction section, ready to climb to the Nth structure construction section;

[0004] Step 2: After the formwork of the Nth structural construction section is removed, the wall attachment device in the wall attachment system is installed;

[0005] Step 3: Use the power system to lift the guide rail of the climbing system to the lower end of the wall attachment device, and remove the lower end wall attachment device;

[0006] Step 4: Use the jack to rotate the guide rail around the attachment point and tilt the guide rail to a certain angle;

[0007] Step 5: Continue to lift the guide rail to the wall attachment device of the Nth structural construction section and fix it;

[0008] Step 6: Use the power system to drive the frame system to drive the formwork system to climb one floor height, complete the hydraulic climbing formwork climbing and enter the N+1 structure construction section construction process.

[0009] This construction method has a complex operation process, a small scope of application and certain safety hazards. For example, in multiple continuous variable-section construction sections, the climbing formwork frame always remains tilted, materials stacked on the frame are prone to slipping, and there are also safety hazards for construction workers on the frame. This construction method is only applicable to variable-section construction with a single contraction spacing of less than or equal to 150mm. If the single contraction spacing is greater than 150mm, it will be more difficult for the guide rail to enter the upper wall-mounted device. At the same time, if the tilt angle of the frame is too large, it will interfere with the top steel bars. Summary of the Invention

Finally, after the wall-attaching sliding device 22 carries the climbing formwork wall-attaching device 24 and the connected frame into place, the force of the entire hydraulic climbing formwork frame is transmitted to the structure.

A proximity switch 6 is installed on the wall-attached sliding device 22. When the wall-attached sliding device 22 slides to the side wall of the structure, a feedback signal is sent to the electric control center to stop driving the sliding bearing.

The sliding assembly is composed of a sliding beam, a pulley block, and a limiter. The sliding beam is fixed to the top integrated platform beam, and the pulley block can slide on the sliding beam. A rotatable and displaceable limiter (set) is provided on the sliding beam. The limiter is used to control the sliding distance of the frame to prevent the frame from over-slipping. Specifically, the limiter can be an angle steel, which is connected to the preset bolt holes on the sliding beam by bolts.

[0123] like Figure 11 As shown, in one embodiment of the hydraulic climbing formwork construction platform that can adapt to variable cross-sections of buildings according to the present invention, the electric control center is connected to the pulley group 12 of the sliding assembly 1, and the electric control center drives the pulley group 12 to slide along the sliding beam 11; the electric control center sends a signal to drive the sliding bearings of a single or multiple machine-mounted wall-attached sliding mechanisms 2 to slide synchronously with the pulley group 12 of the sliding assembly.

[0124] Here, the pulley assembly of the sliding assembly 1 is driven by an electric control center arranged on the top of the integrated platform and slides along the sliding beam 11.

[0125] like Figure 12 As shown, the electric control center sends a signal to drive the sliding bearings of a single or multiple machine position wall-mounted sliding mechanism 2 and the pulley group 12 of the sliding assembly to slide synchronously, and a proximity switch is set at the wall-mounted sliding mechanism to control the sliding distance.

[0126] According to another aspect of the present invention, there is also provided a construction method of the hydraulic climbing formwork construction platform adapted to variable cross-sections of buildings, the method comprising:

[0127] like Figure 13 As shown, the first step:

[0128] 11) Using a hydraulic lifting device, the frame of the hydraulic climbing formwork construction platform adapted to the building's variable cross-section is raised to the N-1 structure construction section; wherein, the cross-sections of the N-1 structure construction section and below are wider, and the cross-sections of the N structure construction section and above are narrower;

[0129] 12) After installing the first wall-attached sliding mechanism embedded parts of the Nth structure construction section through the telescopic platform 3 at the Nth structure construction section of the frame, the concrete of the Nth structure construction section is cast together with the first wall-attached sliding mechanism embedded parts;

[0130] 13) During the maintenance period of the Nth structural construction section, i.e., the first variable-section construction section, the reinforcement of the Nth structural construction section is tied; through the telescopic platform 3 at the position of the N+1 structural construction section of the frame, the second wall-attached sliding mechanism embedded parts are embedded at N+1.

[0131] like Figure 14 As shown, the second step:

[0132] 21) After the Nth structural construction section is cured, the formwork is removed and lifted to the N+1th structural construction section;

[0133] 22) Installing the first wall-attaching sliding mechanism 2 at the embedded part of the first wall-attaching sliding mechanism of the Nth structure through the telescopic platform 3 at the construction section of the Nth structure of the frame, and providing a spacer between the wall-attaching sliding device 22 of the first wall-attaching sliding mechanism 2 and the structure, so as to adjust the second gap distance between the upper portion of the lower section of the frame and the side wall of the adjacent structure through the spacer;

[0134] 23) Through the telescopic platform 3 at the position of the N+1 structural construction section of the frame, together with the second wall-attached sliding mechanism embedded parts, the mold is closed to cast the concrete of the N+1 structural construction section, that is, the second variable cross-section construction section.

[0135] like Figure 15 As shown, the third step:

[0136] 31) During the maintenance of the N+1 structural construction section, the frame is raised one floor height by the hydraulic lifting device, and the upper part of the lower section of the frame is attached to the first wall-attached sliding mechanism 2 of the N structural construction section and fixed. At this time, the lower part of the lower section of the frame is located in the N-1 structural construction section;

[0137] Here, the frame needs to be unfastened before each climb;

[0138] 32) Through the telescopic platform 3 at the N+2 structural construction section of the frame, the steel bars of the N+2 structural construction section are tied and the conventional wall-attached device embedded parts of the N+2 structural construction section are embedded.

[0139] Here, the conventional wall attaching device is an ordinary wall attaching device without a sliding function.

[0140] like Figure 16 As shown, step 4:

[0141] 41) After the N+1 structural construction section is cured, the formwork is removed and lifted to the N+2 structural construction section;

[0142] 42) Install the second wall-attaching sliding mechanism 2 of the climbing formwork at the embedded part of the second wall-attaching sliding mechanism of the N+1 structure, and set a spacer between the wall-attaching sliding device 22 of the second wall-attaching sliding mechanism 2 and the structure, so that the second gap distance between the upper part of the lower section of the frame and the structure is adjusted to be equal to the first gap distance between the lower part of the lower section of the frame and the structure, and the gap distance between the side walls of the adjacent structures, so as to ensure that the first wall-attaching sliding device 22 and the second wall-attaching sliding device 22 are perpendicular, and further ensure that the frame connected by the first wall-attaching sliding device 22 and the second wall-attaching sliding device 22 is in a vertical state, so that the guide rail of the hydraulic lifting device is also in a vertical state, and the subsequent vertical climbing can be avoided to avoid tilting;

[0143] Here, after the upper portion of the lower section of the frame is lifted and attached to the N+1 structural construction section, the second gap distance between the upper portion of the lower section of the frame and the side wall of the adjacent structure in step 22 becomes the first gap distance between the lower portion of the lower section of the frame and the side wall of the adjacent structure.

[0144] 43) Through the telescopic platform 3 at the position of the N+2 structural construction section of the frame, together with the conventional wall-attached device embedded parts of the N+2 structural construction section, the concrete of the N+2 structural construction section, i.e. the third variable-section construction section, is cast in place.

[0145] like Figure 17 As shown, step 5:

[0146] 51) During the maintenance of the N+2 structure construction section, after the connection and fixation between the first wall-attached sliding mechanism 2 of the N structure construction section and the frame is released, the vertical frame is vertically climbed one floor height by the hydraulic lifting device, and the upper part of the lower section of the frame is attached to the second wall-attached sliding mechanism of the N+1 structure construction section and connected and fixed. At this time, the lower part of the lower section of the frame is located in the N structure construction section;

[0147] 52) Remove the spacers at the first and second wall-mounted sliding mechanisms, and according to the variable cross-section separation distance of the Nth structural construction section, transfer the limiter of the frame sliding assembly to the limit position of the next third screw hole of the sliding beam 11;

[0148] 53) The electric control center switches to the joint control start signal, driving the sliding components 1 and the wall-mounted sliding mechanisms 2 of multiple sets of machine positions to slide synchronously toward the structure. When the proximity switch sends a position signal, the electric control center sends a joint control stop signal; each several position includes an upper sliding component 1 and a lower wall-mounted sliding mechanism 2;

[0149] 54) Check whether each camera position has slid into place. If there is a camera position that has not yet slid into place, the electric control center switches to the single control start signal to drive the sliding assembly 1 and the wall-mounted sliding mechanism 2 of the single camera position to slide into place synchronously.

[0150] like Figure 18 As shown, step 6:

[0151] 61) After the frame slides into place, the steel bars of the N+3 structure construction section are tied through the telescopic platform 3 at the N+3 structure construction section of the frame, and the embedded parts of the conventional wall attachment device of the N+3 structure construction section are pre-embedded;

[0152] 62) After the curing of the N+2 structural construction section is completed, the formwork is removed and lifted to the N+3 structural construction section, and the concrete of the N+3 construction section is poured;

[0153] 63) At this point, the sliding of the variable-section climbing formwork is completed and the standard section construction process begins.

[0154] In summary, the present invention aims at the needs of stacking structural construction materials and improving the adaptability of building (structure) cross-section changes, and can solve the problems of narrow climbing formwork stacking space, complex variable cross-section construction operations, low safety, and small scope of application.
