Description

Technical Field

[0001] The invention relates to the technical field of top formwork construction, and in particular to a same-layer frame mutual climbing self-lifting support system and a climbing device and a lifting method thereof. Background Art

[0002] The top formwork construction integrated platform used for (super) high-rise building structure construction has good bearing capacity and construction equipment integration capabilities.

[0003] However, in the prior art, a multi-layer concrete main structure is usually used to install the existing self-lifting support system, that is, the self-lifting support system can only be installed after at least two layers of the concrete main structure are constructed. In addition, the self-lifting support system occupies a multi-layer structure, which is not convenient for subsequent construction operations such as secondary structure and exterior wall painting.

[0004] In addition, the existing self-lifting support system is susceptible to multiple effects of installation deviation, structural construction deviation and large load during construction during the jacking operation. The self-lifting support system will have large displacement and deformation during the jacking operation, and the self-lifting support system has weak adaptability to deviation, resulting in inaccurate jacking position. Therefore, the existing self-lifting support system needs to spend a lot of time and manpower to adjust its position deviation. Summary of the invention

[0005] The main purpose of the present invention is to provide a same-level frame mutual climbing self-lifting support system and its climbing device and lifting method, aiming to achieve the same-level climbing of the support frame and the climbing frame, so that the construction integrated platform can intervene in the construction of the concrete main structure as early as possible.

[0006] To achieve the above-mentioned purpose, the present invention provides a climbing device of a same-layer frame mutual climbing self-lifting support system, comprising a load-bearing member, a climbing frame, a telescopic mechanism and a support frame, wherein:

[0007] The climbing frame and the supporting frame can be hung on the outside of the same load-bearing member, and a guiding structure is arranged between the climbing frame and the supporting frame to realize mutually guided climbing. A buffer balancing mechanism is arranged above the supporting frame, and the telescopic mechanism includes a cylinder body and a telescopic rod. The bottom of the telescopic rod is movably connected to the bottom of the climbing frame through a rotating structure, and the cylinder body is penetrated through the inner cavity of the supporting frame. An upper flange is fixed above the cylinder body to abut against the top end surface of the buffer balancing mechanism, and a lower flange is fixed below the cylinder body to abut against the bottom end surface of the supporting frame. The cylinder body and the supporting frame can move horizontally.

[0008] Preferably, the buffer balancing mechanism is a spring box, which includes a hollow seat body, a cover body arranged above the seat body, and a spring located in the seat body, and the relative distance between the seat body and the cover body is adjusted by the spring.

[0009] Preferably, the spring box also includes a guide shaft fixed on the seat body and a limit bolt passing through the sides of the seat body and the cover body. The spring is sleeved outside the guide shaft. A limit hole for the limit bolt to pass through is opened on the side of the cover body. When the cover body moves relative to the seat body, the limit bolt limits the maximum displacement of the cover body. The seat body and the cover body are hollow inside for the cylinder body to pass through.

[0010] Preferably, the supporting frame can be accommodated in the concave groove formed by the climbing frame so that the climbing frame and the telescopic mechanism can be simultaneously hung on the outside of the same load-bearing member, and the load-bearing member is provided with an outer claw boot assembly and a first claw assembly, the climbing frame is provided with a second claw assembly that cooperates with the support arm of the outer claw boot assembly, and the supporting frame is provided with an inner claw boot that cooperates with the first claw assembly.

[0011] Preferably, the load-bearing member is arranged at a height corresponding to the height of one layer of the concrete wall, and the claws of the second claw assembly and the first claw assembly are provided with locking mechanisms to lock their rotation, and an elastic material layer is installed on the mating contact surface of the claws through fasteners.

[0012] Preferably, the locking mechanism includes a limit baffle, a pin is passed through the claw to realize its rotation, a limit slot is provided on the head of the pin, and the limit baffle is inserted into the limit slot to limit the rotation of the pin; the claw width of the first claw assembly is smaller than the slot width of the inner claw shoe, and the claw width of the second claw assembly is smaller than the width of the support arm on the outer claw shoe assembly.

[0013] Preferably, the climbing frame includes two side plates and a base connecting the two side plates, the support frame is located in the concave space formed by the two side plates and the base and is hung on the outside of the load-bearing member, an installation groove is opened on the base, the rotating structure is located in the installation groove and the installation position is adjustable; the guide structure includes a guide assembly located on the side of the support frame and a guide groove arranged on the side where the two side plates of the climbing frame are close to each other, the guide assembly is accommodated in the guide groove to guide the lifting and lowering of the support frame.

[0014] The present invention further proposes a same-layer frame mutual climbing self-lifting support system, including the above-mentioned climbing device and also includes a supporting column, the bottom end of the supporting column is rigidly connected to the upper flange of the telescopic mechanism cylinder body, and the top end of the supporting column is rigidly connected to the construction steel platform.

[0015] The present invention further provides a jacking method for a same-layer frame mutual climbing self-lifting support system, comprising the following steps:

[0016] The cylinder body of the control telescopic mechanism is lifted upward, and the lower flange at the bottom of the cylinder body abuts against the lower end surface of the support frame to drive the support frame to be lifted as a whole;

[0017] When the support frame rises to the right position, the cylinder body retracts downward and the first claw assembly cooperates with the inner claw shoe to hang the support frame on the outside of the load-bearing member;

[0018] The telescopic rod of the telescopic mechanism is controlled to retract relative to the cylinder body, thereby driving the climbing frame to rise as a whole;

[0019] When the climbing frame is climbed to the right position, the telescopic rod is extended downward to make the turning claw of the second turning claw assembly fall on the outer claw shoe assembly of the load-bearing member, and the climbing frame is hung on the outer side of the load-bearing member.

[0020] The present invention further provides a method for descending a same-layer frame mutual climbing self-elevating support system, comprising the following steps:

[0021] The telescopic rod of the telescopic mechanism is controlled to extend upward to drive the climbing frame to rise, so that the claw of the second claw assembly and the outer claw shoe assembly are separated, the claw of the second claw assembly is rotated to be stored inside the climbing frame and then locked, and the telescopic rod of the telescopic mechanism is controlled to extend downward to drive the climbing frame to descend;

[0022] When the climbing frame is lowered into place, the claw of the second claw assembly is unlocked to be naturally extended to a horizontal state, and the telescopic rod is controlled to move so that the claw of the second claw assembly falls above the outer claw shoe assembly;

[0023] The control cylinder body extends upward to separate the flap of the first flap assembly from the inner claw shoe, rotates the flap of the first flap assembly to be stored inside the load-bearing member and then locks it, and the control cylinder body moves downward to drive the support frame to descend;

[0024] When the support frame is lowered into place, the claw of the first claw assembly is unlocked to naturally extend to a horizontal state, and the cylinder of the telescopic mechanism is controlled to move so that the claw of the first claw assembly cooperates with the slot of the inner claw shoe to hang the climbing frame on the outside of the load-bearing member.

[0025] The same-layer frame mutual climbing self-lifting support system proposed by the present invention has the following beneficial effects:

[0026] 1. This same-layer frame mutual climbing self-lifting support system adopts a structure with three functions: same-layer frame, mutual guided climbing and good centering. Among them, the same-layer frame means that because the climbing frame and the support frame can be hung on the outside of the same load-bearing member, the self-lifting support system can be installed after one layer of concrete main structure construction. In addition, the self-lifting support system can only occupy one layer of structure, and subsequent construction work such as secondary structure and exterior wall painting is required. Mutually guided climbing means that the climbing frame and the support frame are mutually guided to climb. The specific implementation methods are: one is through the guide structure (guide groove), the second is that the climbing frame is set as the outer frame on the outside of the support frame, and the third is to cooperate with the telescopic mechanism. When the climbing frame does not climb, the support frame climbs with the climbing frame as the fulcrum, and when the support frame does not climb, the climbing frame climbs with the support frame as the fulcrum. Mutually guided climbing is achieved by the connection method of the telescopic mechanism in conjunction with the guide structure. Good centering is achieved through two measures. First, the side panels of the climbing frame are used to ensure that the position of the support frame will not shift too much when climbing or descending. Second, when the centering is poor for smaller sizes during installation, the width of the first claw assembly is smaller than the slot width of the inner claw boot, and the width of the second claw assembly is smaller than the width of the upper support arm of the outer claw boot assembly. At the same time, with the inclined structure of the claw, the climbing frame and the support frame can eliminate position deviations by relying on their gravity and the inclined self-centering structure when they are in place, so that the climbing frame and the support frame are self-centered in a plane contact state. When the centering is poor for larger sizes, the position of the support frame on the lower flange is adjusted by external force, so that the inner claw boot of the support frame and the first claw assembly can be matched, and the matching position of the second claw and the inner claw boot can be adjusted, thereby ensuring the accuracy of the position of the support frame on the load-bearing member when it is lifted or lowered;

[0027] 2. The ball joint structure and the buffer balance mechanism are used together to ensure the effective release of the internal force between the structural parts during the operation of the support lifting system. In addition, the cylinder body and the support frame can be moved. The two points work together to ensure the accuracy of the position of the support frame and the climbing frame on the load-bearing parts. On the other hand, it improves the adaptability of the lifting operation under the multiple influences of installation deviation, structural construction deviation and large load during construction.

[0028] 3. This support lifting system can realize the descending function, which expands the types of construction operations (it can provide a working surface for secondary structures and exterior wall painting, etc.), and facilitates the disassembly of the construction steel platform from below (the construction steel platform can follow the support frame to descend to the bottom of the building instead of being disassembled at a high level as in the prior art).

[0029] 4. This same-layer frame mutual climbing self-lifting support system has the advantages of simple structure, easy disassembly and stable and reliable operation. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0075] The invention provides a same-layer frame-type supporting self-lifting system.

[0076] Reference Figures 1 to 17d In this preferred embodiment, a same-layer frame mutual climbing self-lifting support system (self-lifting refers to a system with a telescopic mechanism to realize the lifting function) includes a climbing device and a supporting column 7. The bottom end of the supporting column 7 is rigidly connected to the upper flange 6.1 of the cylinder body of the telescopic mechanism 6, and the top end of the supporting column 7 is rigidly connected to the construction steel platform 1.

[0077] The climbing device includes a load-bearing member 3, a climbing frame 4, a telescopic mechanism 6 and a support frame 5, wherein the climbing frame 4 and the support frame 5 can be hung on the outside of the same load-bearing member 3 (i.e., the side away from the concrete wall), a guiding structure is provided between the climbing frame 4 and the support frame 5 to achieve mutually guided climbing, a buffer balancing mechanism is provided above the support frame 5, the telescopic mechanism 6 includes a cylinder body and a telescopic rod, the bottom of the telescopic rod is movably connected to the bottom of the climbing frame 4 through a rotating structure (the rotating structure enables the bottom of the telescopic rod to rotate relative to the bottom of the climbing frame 4), the cylinder body is penetrated in the inner cavity of the support frame 5, an upper flange 6.1 is fixed above the cylinder body to abut against the top surface of the buffer balancing mechanism, a lower flange 6.2 is fixed at the bottom of the cylinder body to abut against the bottom end surface of the support frame 5, and the cylinder body and the support frame 5 can move horizontally. The lower flange 6.2 is located between the upper flange 6.1 and the rotating structure.

[0078] The support column 7 can be welded from profiles. The upper end of the support column 7 is rigidly connected to the construction steel platform 1, and the lower end is rigidly connected to the upper flange 6.1 of the cylinder body to achieve the support of the construction steel platform 1 climbing (such as Fig.13 The telescopic mechanism 6 can be a variety of linear motion mechanism forms such as a hydraulic cylinder, a linear guide rod, a screw lift, and an electric cylinder, and the present invention is not limited to this.

[0079] Reference Figures 3a to 3f, this embodiment proposes a specific structure of a load-bearing member 3. The load-bearing member 3 includes a load-bearing member body 3.1, a fastener (bolt 3.2 may be used) for fastening the load-bearing member body 3.1 to the concrete wall, and a first flap assembly 3.3 and an outer claw shoe assembly 3.4 installed on the load-bearing member body 3.1, wherein at least two rows of through holes are provided in the height direction of the load-bearing member body 3.1 for the fasteners to pass through, and the height of the load-bearing member body 3.1 corresponds to the height of one floor of the concrete wall (i.e., the height of the load-bearing member body 3.1 is the height of one floor). The load-bearing member body 3.1 can be welded with Q35B and 42CrMo metal materials to improve the overall structural strength.

[0080] Figure 3a In the embodiment, the load-bearing member body 3.1 is provided with four rows of through holes, and each row is provided with four through holes, and a total of 16 through holes are provided for installing fasteners, so as to avoid the positions of pre-opened holes on the concrete wall.

[0081] In addition, the rotatable concrete structure embedded parts 2 can be flexibly configured according to the construction load and the needs of the concrete structure, such as pre-embedded multiple layers, and each layer is composed of multiple parts. The load-bearing parts 3 are rigidly connected to the rotatable concrete structure embedded parts 2 through fasteners (bolts 3.2), thereby improving the load-bearing capacity of the load-bearing parts 3 and the accuracy of pre-embedding.

[0082] In this embodiment, the load-bearing member body 3.1 is provided with two layers of outer claw shoe assemblies 3.4 as an example for specific description. At this time, it can be lifted up to 1 / 2 and 1 layer height in two modes, so as to achieve a lifting height of half the layer height. When the load-bearing member body 3.1 is provided with three layers of outer claw shoe assemblies 3.4, it can be lifted up to 1 / 3 layer height, 2 / 3 and 1 layer height in three modes, so as to achieve a lifting height of 1 / 3, 2 / 3 or 1 layer height.

[0083] Further, refer to Figure 3b The load-bearing member 3 also includes a layer height adjustment block 3.7 which is detachably connected to the load-bearing member body 3.1. The layer height adjustment block 3.7 is connected to the top end surface or the bottom end surface of the load-bearing member body 3.1. A connecting plate can be provided on the top and bottom of the load-bearing member body 3.1. The connecting plate is processed with a light hole so as to be connected with the vertically adjacent load-bearing member 3 or the layer height adjustment block 3.7 by bolts (refer to Figure 7 ).

[0084] The load-bearing member 3 can first be used as a template for the concrete main structure pouring construction. When the concrete main structure strength reaches the standard, it can be used for the subsequent installation of the climbing frame 4 and the support frame 5. If the main structure construction layer height changes, a layer height adjustment block 3.7 can be added between the upper and lower load-bearing members 3.

[0085] In this embodiment, since the height of the load-bearing member body 3.1 corresponds to the height of one layer of the concrete wall, at least two rows of through holes are provided in the height direction of the load-bearing member body 3.1 for fasteners to pass through, compared with the small-volume load-bearing member body in the prior art (the height of the load-bearing member in the prior art is much smaller than the height of the wall), the self-lifting support system is easy to attach to the side of the concrete wall. In addition, since the height of the load-bearing member body 3.1 corresponds to the height of one layer of the concrete wall, compared with the small-volume wall-attached support in the prior art, its force-bearing area is greatly increased, thereby improving the overall structural strength of the load-bearing member 3.

[0086] Furthermore, at least two rows of outer claw shoe assemblies 3.4 are arranged in the height direction of the load-bearing member body 3.1, and outer claw shoe assemblies 3.4 are arranged on both the left and right sides of the load-bearing member body 3.1. The outer claw shoe assemblies 3.4 are supported under the second flip claw assembly 4.2 of the climbing frame 4 to support it. In other words, at least four outer claw shoe assemblies 3.4 are arranged on one load-bearing member body 3.1, and two rows are arranged on the left and right outer side walls of the load-bearing member body 3.1, so as to realize the same-floor climbing of the self-lifting support system.

[0087] Specifically, refer to Figure 3d The outer claw shoe assembly 3.4 includes an outer claw shoe 3.4.1 for being fitted with the second flap claw assembly 4.2, a vertical rib plate 3.4.3 located below the outer claw shoe 3.4.1 to support it, and a transverse rib plate 3.4.2 connected to the outer claw shoe 3.4.1 on the side close to the concrete wall. The outer claw shoe 3.4.1 can be welded to the load-bearing member body 3.1. The vertical rib plate 3.4.3 supports the lower side of the outer claw shoe 3.4.1 to improve its bearing capacity. Both the vertical rib plate 3.4.3 and the transverse rib plate 3.4.2 can be connected to the load-bearing member body 3.1 by welding, and the welding connection has the advantage of easy installation. The outer claw shoe 3.4.1 can be fully penetrated welded with 42CrMo quenched and tempered material to improve the local bearing capacity.

[0088] Reference Figure 3d The outer claw shoe 3.4.1 has a support arm extending outward, and the support arm has a first inclined surface, a second inclined surface, and a transition arc surface between the first inclined surface and the second inclined surface. The first inclined surface is the top surface of the support arm, and the second inclined surface is the end surface of the support arm close to the concrete wall. The transverse rib plate 3.4.2 is connected to the second inclined surface. The side of the support arm facing the second flap 4.2.1 is a straight surface to fit with it. The outer claw shoe 3.4.1 is provided with a guide inclined surface close to the support arm to guide and limit the first flap 3.3.1.

[0089] Reference Figure 3cThe first flap assembly 3.3 is used to cooperate with the inner claw shoe 5.1.1 of the support frame 5 of the top mold self-lifting support system. The first flap assembly 3.3 includes a first flap 3.3.1 that can rotate relative to the load-bearing member body 3.1, and a first rotating pin shaft assembly 3.5 that penetrates the first flap 3.3.1 and the load-bearing member body 3.1. The second flap 4.2.1 can extend into the groove of the inner claw shoe 5.1.1 to support the support frame 5.

[0090] By setting the first flap assembly 3.3, the function of supporting the support frame 5 to climb up is realized. The first flap assembly 3.3 is installed on the load-bearing member body 3.1 through the first rotating pin assembly 3.5. The first rotating pin assembly 3.5 includes a first pin 3.5.1, a first flat key 3.5.2, a first hexagonal head 3.5.3 and a first limit baffle 3.5.4. The first rotating pin assembly 3.5 is used to realize the rotation function of the first flap 3.3.1 relative to the load-bearing member body 3.1. Rotating the first hexagonal head 3.5.3 can drive the first pin 3.5.1 to rotate.

[0091] Furthermore, a groove is provided inside the load-bearing member body 3.1, and the second flap 4.2.1 can be completely accommodated inside the groove. The second flap 4.2.1 will automatically extend out of the groove under the action of gravity, and when the climbing frame 4 climbs, the second flap 4.2.1 will automatically be stored in the groove under the action of the outer frame of the climbing frame 4, and when the climbing frame 4 climbs into place, the second flap 4.2.1 will automatically extend out of the groove under the action of gravity.

[0092] Further, refer to Figure 3f The first top block 3.1.1 and the second top block 3.1.2 are fixed inside the groove of the load-bearing member body 3.1. The first top block 3.1.1 and the second top block 3.1.2 are used to limit the rotation angle of the first flap 3.3.1, so that the first flap 3.3.1 is in a horizontal state without external force. The first top block 3.1.1 and the second top block 3.1.2 can be fully penetrated welded with 42CrMo quenched and tempered material to improve the local bearing capacity.

[0093] In addition, a shackle 3.6 is installed on the load-bearing member body 3.1, and the shackle 3.6 cooperates with the lifting mechanism to realize the lifting of the load-bearing member body 3.1.

[0094] Specifically, refer to Figure 5cThe buffer balance mechanism is a spring box 5.2, which is detachably mounted (can be installed by screws) on the top of the support frame 5. The spring box 5.2 includes a spring box body 5.2.1 and multiple groups of springs 5.2.2. The spring box body 5.2.1 includes a hollow seat 5.2.1.1 and a cover 5.2.1.2 covering the seat 5.2.1.1. The relative distance between the seat 5.2.1.1 and the cover 5.2.1.2 is adjusted by the spring 5.2.2.

[0095] Further, refer to Figure 5c The spring box 5.2 also includes a guide shaft 5.2.1.3 fixed on the seat body 5.2.1.1 and a limit bolt 5.2.1.4 passing through the side of the seat body 5.2.1.1 and the cover body 5.2.1.2. The spring 5.2.2 is sleeved on the outside of the guide shaft 5.2.1.3. The side of the cover body 5.2.1.2 is provided with a limit hole for the limit bolt 5.2.1.4 to pass through. When the cover body 5.2.1.2 moves relative to the seat body 5.2.1.1, the limit bolt 5.2.1.4 limits the maximum displacement of the cover body 5.2.1.2. The seat body 5.2.1.1 and the cover body 5.2.1.2 are hollow inside to allow the telescopic mechanism 6 to pass through.

[0096] By providing the guide shaft 5.2.1.3, radial deformation of the spring 5.2.2 can be prevented. In addition, the limiting bolt 5.2.1.4 cooperates with the limiting hole to limit the relative movement position between the cover body 5.2.1.2 and the seat body 5.2.1.1, so that the spring is always kept in a compressed state to achieve a buffering function.

[0097] The side and bottom of the seat body 5.2.1.1 are provided with threaded holes. The threaded holes at the bottom are used to install the guide shaft 5.2.1.3, and the threaded holes at the side are used for the limit bolts 5.2.1.4 to pass through.

[0098] When installing the spring box 5.2, first, fix the guide shaft 5.2.1.3 inside the hollow chamber of the seat body 5.2.1.1, then assemble the multiple groups of springs 5.2.2 in the guide shaft 5.2.1.3, and finally, the cover body 5.2.1.2 and the seat body 5.2.1.1 are installed together through the limit bolts 5.2.1.4 on the side. It is necessary to pay attention to make the springs 5.2.2 in the spring box 5.2 always in a pre-stressed state.

[0099] Reference Fig.12a and Figure 12b The multiple groups of springs 5.2.2 in the spring box 5.2 can be in different compression states, thereby balancing and mitigating the eccentric load, displacement deviation and vibration of the construction steel platform 1.

[0100] Further, refer to Fig. 9The support frame 5 can be accommodated in the concave groove formed by the climbing frame 4, and at least two rows of outer claw shoe assemblies 3.4 and two rows of first claw assemblies 3.3 are arranged in the height direction of the load-bearing member 3 (at least two rows of outer claw shoes 3.4.1 are provided for stably supporting the climbing frame 4, and at least two rows of first claw assemblies 3.3 are provided for stably supporting the support frame 5, that is, the climbing frame 4 and the support frame 5 can be hung on the same load-bearing member 3). The climbing frame 4 is provided with a second claw assembly 4.2, and the support frame 5 is provided with an inner claw shoe 5.1.1. The claw of the second claw assembly 4.2 is adapted to the shape of the support arm of the outer claw shoe assembly 3.4, and the slot of the inner claw shoe 5.1.1 is adapted to the shape of the claw of the first claw assembly 3.3.

[0101] Because in the prior art, the support frame 5 is hung on the load-bearing member 3 of the upper layer of the climbing frame 4, that is, the support frame 5 and the climbing frame 4 are not on the same layer, therefore, the climbing frame 4 and the support frame 5 together need to occupy at least two layers of height (therefore, in the prior art, a multi-layer concrete main structure is usually used to install the existing self-lifting support system, that is, the self-lifting support system can be installed only after at least two layers of the concrete main structure are constructed. In addition, the self-lifting support system occupies a multi-layer structure, which is not convenient for subsequent secondary structures and subsequent construction operations such as exterior wall painting). In this embodiment, the support frame 5 is accommodated in the concave groove formed by the climbing frame 4, so that the support frame 5 and the climbing frame 4 can be simultaneously hung on the side of the load-bearing member 3 of the same layer, so that the support frame 5 and the climbing frame 4 together occupy a layer of space, and the self-lifting support system can be installed after one layer of the concrete main structure is constructed, so that the construction steel platform 1 can be involved in the construction of the concrete main structure as soon as possible. In addition, because the self-lifting support system only occupies one layer of structure, it is convenient for subsequent secondary structures and subsequent construction operations such as exterior wall painting. That is to say, the mutual climbing self-lifting support system of the frames on the same level realizes the effect of climbing on the same level (climbing on the same level means that the support frame 5 and the climbing frame 4 can be hung on the load-bearing member 3 on the same level at the same time).

[0102] Specifically, refer to Figures 4a to 4eThe climbing frame 4 includes a climbing frame body 4.1, a second flap assembly 4.2, a second rotating pin assembly 4.3 and a sliding limit structure 4.4. Among them, the climbing frame body 4.1 structure is welded with Q355B and 42CrMo metal materials. The climbing frame body 4.1 is provided with a third top block 4.1.2, a fourth top block 4.1.3 and a guide groove 4.1.1. The third top block 4.1.2 and the fourth top block 4.1.3 cooperate to limit the flipping position of the flap in the second flap assembly 4.2. The third top block 4.1.2 and the fourth top block 4.1.3 can be fully penetrated welded with 42CrMo quenched and tempered materials to improve the local bearing capacity. Two layers of the second flap assembly 4.2 are arranged on the climbing frame 4. The second flap assembly 4.2 includes a second flap 4.2.1, a second elastic material layer 4.2.2 and a screw. The second rotating pin assembly 4.3 includes a second pin 4.3.1, a second flat key 4.3.2, a second limit baffle 4.3.3 and a second hexagonal head 4.3.4. The second pin 4.3.1 and the second flap 4.2.1 are connected by a key. The second flap 4.2.1 can be turned over under its own gravity, and the third top block 4.1.2 and the fourth top block 4.1.3 cooperate to make the second flap 4.2.1 present a horizontal state.

[0103] In this embodiment, the rotating structure is a ball joint structure 6.3. The climbing frame 4 and the supporting frame 5 of this embodiment can be hung on the outside of the same load-bearing member 3, and the following structure is specifically adopted to achieve this: the climbing frame 4 includes two side plates and a base connecting the two side plates, the supporting frame 5 is located in the concave space formed by the two side plates and the base and is hung on the outside of the load-bearing member 3, and an installation groove 4.4.1 is opened on the base, and the ball joint structure 6.3 is located in the installation groove 4.4.1 and the installation position can be adjusted.

[0104] The installation groove 4.4.1 and the limiting bolt group 4.4.2 inside it together form a sliding limiting structure 4.4, so as to adjust and fix the installation position of the ball joint structure 6.3. The size of the ball joint seat 6.3.3 and the lower flange plate 6.2.2 is larger than the rectangular cavity between the spring box 5.2 and the support frame 5. First, the ball joint seat 6.3.3 is assembled in the concave space at the bottom of the climbing frame 4. On the one hand, the ball joint structure 6.3 is limited by the limiting bolt group 4.4.2 and the limiting waist-shaped hole 6.3.4 on the side of the ball joint seat 6.3.3. On the other hand, when the telescopic mechanism is lifted, the telescopic mechanism 6 is lifted to drive the ball joint structure 6.3, thereby driving the climbing frame 4 to rise.

[0105] Further, refer to Figures 5a to 5dThe support frame 5 includes a support frame body 5.1, a spring box 5.2 and a guide assembly 5.3. Two layers of inner claw shoes 5.1.1 can be arranged in the support frame body 5.1. The structure of the inner claw shoes 5.1.1 has structural features such as inclined surfaces, curved surfaces and straight surfaces. The inner claw shoes 5.1.1 can be made of 42CrMo quenched and tempered materials and fully penetrated welded to improve the local bearing capacity. The spring box 5.2 is assembled on the upper part of the support frame body 5.1 by screw connection.

[0106] Reference Figure 4a and Figure 5d The present invention proposes a guide structure. The guide structure includes a guide assembly 5.3 located on the side of the support frame 5 and a guide groove 4.1.1 arranged on the side where the two side plates of the climbing frame 4 are close to each other. The guide assembly 5.3 is accommodated in the guide groove 4.1.1 to guide the lifting and lowering of the support frame 5.

[0107] By setting the guide assembly 5.3 and the guide groove 4.1.1 of the climbing frame 4 to form a guide sliding pair, the mutual guiding effect of the supporting frame 5 and the climbing frame 4 during movement is ensured, that is, the mutual climbing of the frames is guided (the mutual climbing of the frames refers to the climbing frame 4 and the supporting frame 5 supporting each other to achieve relative climbing).

[0108] Reference Figure 5d , this embodiment proposes a specific structure of a guide assembly 5.3: the guide assembly 5.3 includes a guide seat 5.3.1 fixed on the side of the support frame 5 and a wear-resistant plate 5.3.2 detachably mounted on the outer surface of the guide seat 5.3.1. The wear-resistant plate 5.3.2 is made of ZCuSn10P1. The guide assembly 5.3 is connected to the support frame body 5.1 by screws. The wear resistance of the guide assembly 5.3 is improved by setting the wear-resistant plate 5.3.2. The thickness of the wear-resistant plate 5.3.2 of the guide assembly 5.3 is adjustable so as to adjust the spacing of the guide sliding pair between the support frame 5 and the climbing frame 4, and the adjustable spacing ensures the smooth movement of the two.

[0109] Furthermore, the second claw assembly 4.2 and the first claw assembly 3.3 are both provided with locking mechanisms to lock their rotation. The locking mechanisms are provided to achieve the descending function of the same-layer frame mutual climbing self-lifting support system.

[0110] In the prior art, after the main concrete structure is built, the construction steel platform 1 is disassembled at high altitude. High-altitude work not only has certain safety risks but also has low work efficiency (the existing self-lifting support system only has a lifting function). In order to meet the needs of ground disassembly and expansion of construction operations after the construction steel platform 1 completes the construction of the main concrete structure, the support lifting system is required to have a descending function. However, the top form self-lifting support system in the prior art does not have a descending function. In this application, a locking mechanism is provided to limit the rotation of the flap, so as to realize the function that the climbing frame 4 can descend relative to the load-bearing member 3. On the one hand, it is convenient for the construction steel platform 1 to be disassembled from below, and on the other hand, the descended construction steel platform 1 can provide a working surface for secondary structure and exterior wall painting operations.

[0111] Specifically, refer to Figure 4c This embodiment proposes a specific structure of a locking mechanism: the locking mechanism includes a limit baffle (the second limit baffle 4.3.3 corresponds to the second flap 4.2.1, and the first limit baffle 3.5.4 corresponds to the first flap 3.3.1), a pin is provided on the flap to realize its rotation, a limit slot is provided at the head of the pin, and the limit baffle is inserted into the limit slot to limit the rotation of the pin. The flaps of the second flap assembly 4.2 and the first flap assembly 3.3 are both installed by the pin to realize rotation.

[0112] Specifically, the limit baffle can be detachably installed on the load-bearing member 3 and the climbing frame 4. For example, two groups of bolt holes can be set on the load-bearing member 3 and the climbing frame 4. When the bolts passing through the limit baffle are installed in the first group of bolt holes, at this time, the limit baffle is inserted into the annular positioning groove opened at the end of the pin shaft, thereby limiting the pin shaft to play an axial positioning role and prevent the pin shaft from loosening. When the bolts passing through the limit baffle are installed in the second group of bolt holes, the limit baffle is inserted into the special-shaped limit groove on the inner side of the annular positioning groove. At this time, the pin shaft cannot rotate, thereby achieving locking of the flap. The limit baffle adopting this structure is simple in structure, easy to manufacture, and low in cost. The limit baffle can also be realized by sliding in a manner to achieve different installation positions corresponding to the two states.

[0113] Further, refer to Figure 3c , Figure 3e , Figure 4b and Figure 4c The outer wall of the pin shaft is provided with a limiting protrusion, and the inner wall of the through hole through which the flap is used for the pin shaft to pass is provided with a positioning groove, and the limiting protrusion is accommodated in the positioning groove to fix the flap and the pin shaft. The circumferential rotation of the pin shaft is limited by the cooperation of the limiting protrusion and the positioning groove, and the installation process of the flap and the pin shaft is very simple.

[0114] Further, refer to Fig.11b , the width of the first claw assembly 3.3 is smaller than the slot width of the inner claw shoe 5.1.1, refer to Figure 8bThe width of the second claw assembly 4.2 is smaller than the width of the upper support arm of the outer claw shoe assembly 3.4.

[0115] The upper support arm of the outer claw shoe assembly 3.4, the inner claw shoe 5.1.1 and the flip claw all have straight and inclined surface structures. Fig.11a and Fig.11b , when there is a certain deviation in the spatial distance between the load-bearing member 3 and the support frame 5, the support frame 5 can eliminate the position deviation by relying on its gravity and the self-centering structure of the inclined plane between the two when it is in place, so that the load-bearing member 3 and the support frame 5 are self-centered in a plane contact state. The outer claw boot 3.4.1 of the load-bearing member 3 and the flip claw of the climbing frame 4 adopt the same principle, which can eliminate the position deviation and self-center in a plane contact state when they are in place. Specifically, the contact surface between the second flip claw 4.2.1 and the outer claw boot 3.4.1 includes a combination of a straight surface, an arc surface and an inclined surface. On the one hand, the combination of these three surfaces can realize vertical and horizontal load-bearing. On the other hand, the combined structure of the three surfaces ensures that the climbing frame 4 falls on the outer claw boot 3.4.1 of the load-bearing member 3 along the inclined plane in a self-centered manner under the action of gravity, thereby ensuring the centering of the supporting lifting system.

[0116] Further, refer to Figure 3c and Figure 4b The mating contact surface of the flap is provided with an elastic material layer (the first flap 3.3.1 corresponds to the first elastic material layer 3.3.2, and the second flap 4.2.1 corresponds to the second elastic material layer 4.2.2) by fasteners. By providing the elastic material layer, the elastic material layer deforms under external force, thereby ensuring that the flap and the outer claw shoe 3.4.1 or the inner claw shoe 5.1.1 can fit closely to bear the force together.

[0117] Reference Figure 6 The telescopic mechanism 6 is provided with an upper flange 6.1 and a lower flange 6.2, wherein the upper flange 6.1 is rigidly connected to the supporting column 7. The upper flange 6.1 includes an upper flange 6.1.1 and an upper flange plate 6.1.2, which are connected together by bolts; the lower flange 6.2 includes a lower flange 6.2.1 and a lower flange plate 6.2.2, which are connected together by bolts. The bottom of the telescopic mechanism 6 is a ball joint structure 6.3, which includes a ball 6.3.1, a ball joint seat 6.3.3, a ball joint cover 6.3.2 and a bolt group. The side of the ball joint seat 6.3.3 is a limiting waist-shaped hole 6.3.4.

[0118] Reference Figure 7 The load-bearing member 3 is first used as a template for the concrete main structure pouring construction. When the concrete main structure reaches the strength standard, it can be used for the subsequent installation of the climbing frame 4 and the support frame 5. The two load-bearing members 3 can be connected together by bolts. If the height of the main structure construction layer changes, a layer height adjustment block 3.7 can be added between the upper and lower load-bearing members 3.

[0119] Reference Fig.12a and Figure 12b The sizes of the ball joint seat 6.3.3 and the lower flange plate 6.2.2 are both larger than the size of the rectangular cavity between the spring box 5.2 and the support frame 5. Fig.12a As shown, during the lifting process, when the upper flange 6.1 and the spring box 5.2 are in a disengaged state (no contact between the two), the lower flange 6.2 is in a contact state with the lower end surface of the support frame 5. Therefore, the cylinder body can drive the support frame 5 to lift. Figure 12b As shown, when the lifting is completed, when the upper flange 6.1 falls on the spring box 5.2, the spring box 5.2 is in a compressed state due to the external force. At this time, the lower flange 6.2 is in a disengaged state from the lower end surface of the support frame 5.

[0120] The installation process of the same-layer frame inter-climbing self-lifting support system is as follows.

[0121] First, refer to Fig.12a and Figure 12b During installation, install the ball joint seat 6.3.3 in the mounting groove 4.4.1 at the bottom of the climbing frame 4, and use the limiting bolt group 4.4.2 and the limiting waist-shaped hole 6.3.4 on the side of the ball joint seat 6.3.3 to limit the position; in addition, the lower flange plate 6.2.2 needs to be removed. The telescopic mechanism 6 passes through the spring box 5.2 and the middle rectangular cavity of the support frame 5 in turn until the upper flange plate 6.1.1 of the telescopic mechanism 6 falls on the spring box 5.2. Then, reinstall the lower flange plate 6.2.2 on the lower flange plate 6.2.1, and connect the telescopic mechanism 6 and the climbing frame 4 together through the ball joint structure 6.3. The supporting column 7 and the upper flange plate 6.1.1 of the telescopic mechanism 6 are connected together. Thereby realizing the installation of the mutual climbing self-lifting support system of the same-layer frame. Subsequently, the supporting column 7 and the construction steel platform 1 are installed in sequence.

[0122] Reference Fig.12a and Figure 12b When the upper flange 6.1.1 is located on the spring box 5.2, the spring box 5.2 is in a compressed state due to external force. The multiple groups of springs 5.2.2 in the spring box 5.2 can be in different compression states, thereby balancing and mitigating the eccentric load, displacement deviation and vibration of the construction steel platform 1. When the upper flange 6.1.1 is located on the spring box 5.2, the ball joint structure 6.3 at the head of the telescopic mechanism 6 can rotate freely, ensuring that the first flap 3.3.1 of the load-bearing member 3 and the inner claw shoe 5.1.1 of the support frame 5 fit in multiple surfaces, thereby realizing the load transfer of the construction steel platform 1 to the support frame 5.

[0123] Reference Fig.14a and Fig.14b, the supporting lifting system has a layer of load-bearing parts 3 when it is initially installed. A layer of load-bearing parts 3 is first used as a template for the pouring construction of the concrete main structure. When the strength of the concrete main structure reaches the standard, the supporting lifting system is installed. First, install the traversable concrete structure embedded parts 2 and the load-bearing parts 3, and then the climbing frame 4 is placed on the load-bearing parts 3. Subsequently, the supporting frame 5 is placed on the load-bearing parts 3. Then the telescopic mechanism 6 is installed, and its head is movably connected to the climbing frame 4 through a ball joint. Its lower flange plate 6.2.2 can lift the supporting frame 5, and its upper flange plate 6.1.2 can be placed on the spring box 5.2 of the supporting frame 5, and its upper flange 6.1 is connected to the supporting column 7 to support the construction steel platform 1. The supporting lifting system includes a lifting function and a lowering function. The supporting lifting system has at least two layers of load-bearing parts 3 during the lifting, lifting and lowering movements.

[0124] The lifting process of the same-layer frame mutual climbing self-lifting support system is as follows (including two major steps of lifting the support frame 5 and the climbing frame 4).

[0125] Reference Figures 15a to 15cWhen the telescopic mechanism 6 extends (the cylinder body extends relative to the telescopic rod), its lower flange plate 6.2.2 gradually contacts the bottom of the support frame 5, while its upper flange plate 6.1.1 and the spring box 5.2 gradually separate, so that the lower flange plate 6.2.2 supports the support frame 5 to rise continuously during the extension movement, and the bottom of the support frame 5 and the lower flange plate 6.2.2 can slide under external force. During the movement, the load of the construction steel platform 1 is transmitted to the telescopic mechanism 6 through the upper flange plate 6.1.1. The ball joint structure 6.3 is used at the head of the telescopic mechanism 6 to ensure the self-centering effect during its telescopic movement. When the support frame 5 rises to its position, the telescopic mechanism 6 retracts (that is, the cylinder body moves slightly downward for a distance), so that the inner claw shoe 5.1.1 of the support frame 5 and the first flap 3.3.1 are simultaneously attached to each other to bear the force together. At this time, the support frame 5 is hung on the load-bearing member 3. Of course, during the retraction movement, if the inner claw shoe 5.1.1 of the support frame 5 and the first flap 3.3.1 cannot fit together on multiple sides due to installation deviation, excessive structural construction deviation and large deformation under large load during construction, the position of the support frame 5 on the lower flange plate 6.2.2 can be adjusted by external force to achieve the inner claw shoe 5.1.1 and the first flap 3.3.1 to fit together on multiple sides at the same time. Continuing to retract realizes the gradual fit of the upper flange 6.1.1 and the spring box 5.2. After the jacking is completed, the load of the construction steel platform 1 is transmitted to the upper flange 6.1.1, the support frame 5, the load-bearing member 3, the turnover concrete structure embedded member 2 and finally to the concrete main structure in sequence through the supporting column 7. During the lifting process, the load of the construction steel platform 1 is successively transmitted to the upper flange plate 6.1.2 of the telescopic mechanism 6, the ball joint structure 6.3, the bottom of the climbing frame 4, the second flap 4.2.1, the load-bearing member 3, the traversable concrete structure embedded part 2 and finally to the concrete main structure through the supporting column 7. (This section specifically describes the lifting of the climbing frame 4)

[0126] Reference Figures 16a to 16cWhen the support frame 5 rises to the upper load-bearing member 3, the climbing frame 4 can be lifted and moved upward by the telescopic mechanism 6. During the lifting process of the climbing frame 4, its second flap 4.2.1 contacts the outer claw boot 3.4.1 of the load-bearing member 3, thereby realizing that the second flap 4.2.1 flips inside the climbing frame 4. When the climbing frame 4 continues to rise, the second flap 4.2.1 gradually breaks away from the contact with the outer claw boot 3.4.1 and flips under its own gravity. At the same time, the second flap 4.2.1 is in a horizontal state in a natural state through the limit of the top block. Then, the telescopic mechanism 6 extends (i.e., the telescopic rod moves downward), thereby driving the climbing frame 4 to descend. The self-centering structure of the second flap 4.2.1 and the outer claw boot 3.4.1 of the climbing frame 4 realizes the self-centering in the plane contact state when the position deviation can be eliminated when landing. During the movement, the ball joint structure 6.3 is in a free sliding and rotating state, thus ensuring that after the lifting is completed, the second flap 4.2.1 and the outer claw shoe 3.4.1 are simultaneously attached to each other to bear the load. Of course, the lifting can be carried out on a non-whole floor basis as required. The lifting function realizes the central assembly of the climbing frame 4 on the load-bearing member 3. (Lifting of the support frame 5)

[0127] The descending process of this same-layer frame inter-climbing self-lifting support system is as follows.

[0128] Reference Figures 17a to 17d First, the telescopic mechanism 6 retracts to lift the climbing frame 4 (the telescopic rod moves upward to separate the second flap claw from the outer claw shoe 3.4.1), and then the second hexagonal head 4.3.4 is rotated to drive the second flap claw 4.2.1 to flip inside the climbing frame 4 and lock the second flap claw 4.2.1, and then the telescopic mechanism 6 extends (the telescopic rod moves downward), so that the climbing frame 4 moves down to the next layer of the load-bearing member 3 and restores the second flap claw 4.2.1 to a horizontal state (i.e., the lock is released and it is in an extended state), so that the second flap claw 4.2.1 and the outer claw shoe 3.4.1 are in contact with each other on multiple surfaces at the same time to bear the load together, thereby realizing the descent of the climbing frame 4. After the climbing frame 4 is lowered, first, the telescopic mechanism 6 extends (the cylinder moves upward) to disengage the support frame 5 from the first flap 3.3.1, and then the first hexagonal head 3.5.3 of the upper and lower load-bearing members 3 is rotated to drive the second flap 4.2.1 to flip inside the load-bearing member 3 and lock it, and then the long-stroke telescopic mechanism 6 retracts, so that the support frame 5 moves down to the next layer of load-bearing members 3 and restores the horizontal state of the first flap 3.3.1, so that the first flap 3.3.1 and the inner claw shoe 5.1.1 are simultaneously attached to each other on multiple surfaces to bear the load together, thereby realizing the lowering of the support frame 5. Of course, the lowering can be carried out in a non-whole-layer manner according to the construction needs. After the lowering is completed, the long-stroke telescopic mechanism 6 can also be used to bear the load of the construction steel platform 1 and transmit it to the climbing frame 4, the load-bearing member 3, the turnover concrete structure embedded part 2 in sequence until the concrete main structure.

[0129] The same-layer frame mutual climbing self-lifting support system proposed in this embodiment has the following beneficial effects:

[0130] 1. This same-layer frame mutual climbing self-lifting support system adopts a structure with three functions: same-layer frame, mutual guided climbing and good centering. Among them, the same-layer frame means that because the climbing frame 4 and the support frame 5 can be hung on the outside of the same load-bearing member, the self-lifting support system can be installed after one layer of concrete main structure construction. In addition, the self-lifting support system can only occupy one layer of structure, and subsequent secondary structure and exterior wall painting and other subsequent construction operations. Mutually guided climbing means that the climbing frame 4 and the support frame 5 are mutually guided to climb. The specific implementation methods are: one is through the guide structure (guide groove 4.1.1), the second is that the climbing frame is set as an outer frame on the outside of the support frame 5, and the third is to cooperate with the telescopic mechanism 6. When the climbing frame 4 does not climb, the support frame 5 climbs with the climbing frame 4 as the fulcrum, and when the support frame 5 does not climb, the climbing frame 4 climbs with the support frame 5 as the fulcrum. Good centering is achieved through two measures. First, by relying on the side plates of the climbing frame 4, it is ensured that the position of the supporting frame 5 will not shift too much when climbing or descending. Secondly, when the installation occurs and the centering is poor for a smaller size, the width of the first claw assembly 3.3 is smaller than the slot width of the inner claw shoe 5.1.1, and the width of the second claw assembly 4.2 is smaller than the width of the upper support arm of the outer claw shoe assembly 3.4. At the same time, in conjunction with the inclined structure of the claw, when the climbing frame 4 and the supporting frame 5 are in place, the position deviation can be eliminated by relying on their gravity and the inclined self-centering structure, so that the climbing frame 4 and the supporting frame 5 are self-centered in a plane contact state. When the centering property of the larger size is not good, the position of the support frame 5 on the lower flange can be adjusted by external force, so that the inner claw shoe 5.1.1 of the support frame 5 and the first flap claw assembly 3.3 can be matched, so that the matching position of the second flap claw 4.2.1 and the inner claw shoe 5.1.1 can be adjusted, thereby ensuring the accuracy of the position of the support frame 5 on the load-bearing member 3 when it is lifted or lowered;

[0131] 2. The ball joint structure 6.3 and the buffer balance mechanism are used in combination to ensure the effective release of the internal force between the structural parts during the operation of the support lifting system. In addition, the cylinder body and the support frame 5 can be moved. The two points work together to ensure the accuracy of the position of the support frame 5 and the climbing frame 4 on the load-bearing member 3, and on the other hand, to improve the adaptability of the lifting operation under the multiple influences of installation deviation, structural construction deviation and large load during construction;

[0132] 3. This supporting lifting system can realize the descending function. On the one hand, it expands the types of construction operations (it can provide a working surface for secondary structures and exterior wall painting, etc.), and on the other hand, it is convenient for the construction steel platform 1 to be disassembled from the bottom (the construction steel platform 1 can follow the supporting frame 5 to descend to the bottom of the building instead of being disassembled at a high level as in the prior art).

[0133] 4. This same-layer frame mutual climbing self-lifting support system has the advantages of simple structure, easy disassembly and stable and reliable operation.

[0134] The present invention further proposes a climbing device for a same-layer frame mutual climbing self-lifting support system.

[0135] In this preferred embodiment, a climbing device of a same-layer frame mutual climbing self-lifting support system includes a load-bearing member 3, a climbing frame 4, a telescopic mechanism 6 and a support frame 5, wherein:

[0136] Both the climbing frame 4 and the supporting frame 5 can be hung on the outside of the load-bearing member 3. A buffer balancing mechanism is arranged above the supporting frame 5. The telescopic mechanism 6 includes a telescopic rod and a cylinder body which is sleeved on the outside of the telescopic rod and is telescopic relative to the telescopic rod. The bottom of the telescopic rod is movably connected to the bottom of the climbing frame 4 through a rotating structure. The cylinder body is passed through the supporting frame 5. An upper flange 6.1 is fixed on the top of the cylinder body to abut against the top end surface of the buffer balancing mechanism. A lower flange is fixed on the bottom of the cylinder body to abut against the bottom end surface of the supporting frame 5. The cylinder body and the supporting frame 5 can move horizontally.

[0137] In this embodiment, the buffer balancing mechanism is a spring box 5.2, which includes a hollow seat body 5.2.1.1, a cover body 5.2.1.2 covering the seat body 5.2.1.1 and a spring 5.2.2 located in the seat body 5.2.1.1, and the relative distance between the seat body 5.2.1.1 and the cover body 5.2.1.2 is adjusted by the spring 5.2.2.

[0138] Furthermore, the spring box 5.2 also includes a guide shaft 5.2.1.3 fixed on the seat body 5.2.1.1 and a limit bolt 5.2.1.4 passing through the sides of the seat body 5.2.1.1 and the cover body 5.2.1.2. The spring 5.2.2 is sleeved on the outside of the guide shaft 5.2.1.3. A limit hole for the limit bolt 5.2.1.4 to pass through is opened on the side of the cover body 5.2.1.2. When the cover body 5.2.1.2 moves relative to the seat body 5.2.1.1, the limit bolt 5.2.1.4 moves up and down relative to the limit hole. The seat body 5.2.1.1 and the cover body 5.2.1.2 are hollow inside to allow the telescopic mechanism 6 to pass through.

[0139] The height of the load-bearing member 3 is set to correspond to the height of one floor of the concrete wall. The supporting frame 5 can be accommodated in the concave groove formed by the climbing frame 4. The climbing frame 4 is provided with a second claw assembly 4.2, and the supporting frame 5 is provided with an inner claw boot 5.1.1. At least two rows of outer claw boot assemblies 3.4 and first claw assemblies 3.3 are arranged in the height direction of the load-bearing member 3. The claws of the second claw assembly 4.2 are adapted to the support arm shape of the outer claw boot assembly 3.4, and the slots of the inner claw boot 5.1.1 are adapted to the claw shape of the first claw assembly 3.3.

[0140] The flaps of the second flap assembly 4.2 and the first flap assembly 3.3 are both provided with locking mechanisms to lock their rotation, and an elastic material layer is installed on the mating contact surface of the flaps through fasteners.

[0141] In this embodiment, the locking mechanism includes a limit baffle, a pin is passed through the claw to realize its rotation, a limit slot is provided on the head of the pin, and the limit baffle is inserted into the limit slot to limit the rotation of the pin; the claw width of the first claw assembly 3.3 is smaller than the slot width of the inner claw boot 5.1.1, and the claw width of the second claw assembly 4.2 is smaller than the width of the support arm on the outer claw boot assembly 3.4.

[0142] The rotating structure is a ball joint structure. In this embodiment, the climbing frame 4 and the supporting frame 5 can be hung on the outside of the same load-bearing member, which is specifically realized by the following structure: the climbing frame 4 includes two side plates and a base connecting the two side plates, the supporting frame 5 is located in the concave space formed by the two side plates and the base and is hung on the outside of the load-bearing member 3, and a mounting groove 4.4.1 is opened on the base, and the ball joint structure is located in the mounting groove 4.4.1 and the mounting position can be adjusted.

[0143] The climbing device of the same-layer frame mutual climbing self-lifting support system proposed in this embodiment has the following beneficial effects:

[0144] 1. Since the cylinder body and the support frame 5 are movable, the position of the support frame 5 on the lower flange can be adjusted by external force, so that the inner claw shoe 5.1.1 of the support frame 5 and the first flap claw assembly 3.3 can be matched, so that the installation position of the second flap claw 4.2.1 and the inner claw shoe 5.1.1 can be adjusted, thereby ensuring the accuracy of the position of the support frame 5 on the load-bearing member 3 when it is lifted or lowered;

[0145] 2. The ball joint structure 6.3 and the buffer balance mechanism are used in combination to ensure the effective release of the internal force between the structural parts during the operation of the support lifting system. In combination with the movable between the cylinder body and the support frame 5, the two points work together to ensure the accuracy of the position of the support frame 5 and the climbing frame 4 on the load-bearing member 3, and on the other hand, to improve the adaptability of the lifting operation under the multiple influences of installation deviation, structural construction deviation and large load during construction (construction deviation and construction load are external causes of misalignment, and insufficient internal guide centering structure is an internal cause. This application improves external and internal causes to ensure centering);

[0146] 3. The support frame 5 is accommodated inside the climbing frame 4, and the two can be integrated and installed on one layer, thereby solving the problem that the existing self-lifting support system cannot be installed and lifted on the same structural layer, so that the construction steel platform 1 can be involved in the construction of the concrete main structure as early as possible, and the adaptability and construction efficiency of the construction steel platform 1 are improved, and the construction period of the main structure is shortened;

[0147] 4. This climbing device can realize the descending function. On the one hand, it expands the types of construction operations (it can provide a working surface for secondary structures and exterior wall painting, etc.), and on the other hand, it is convenient for the construction steel platform 1 to be disassembled from the bottom (the construction steel platform 1 can follow the support frame 5 to descend to the bottom of the building instead of being disassembled at a high level as in the prior art).

[0148] 5. This climbing device has the advantages of simple structure, easy disassembly and stable and reliable operation.

[0149] The present invention further proposes a jacking method for a same-layer frame mutual climbing self-lifting support system.

[0150] In this preferred embodiment, a jacking method based on the above-mentioned same-layer frame mutual climbing self-lifting support system includes the following steps:

[0151] Step S10, controlling the cylinder of the telescopic mechanism 6 to lift upward, and the lower flange at the bottom of the cylinder abuts against the lower end surface of the support frame 5 to drive the support frame 5 to lift as a whole;

[0152] Step S20, when the support frame 5 rises to the right position, the cylinder body retracts downward and the first claw assembly 3.3 cooperates with the inner claw shoe 5.1.1 to hang the support frame 5 on the outside of the load-bearing member 3;

[0153] Step S30, the telescopic rod of the telescopic mechanism 6 is retracted relative to the cylinder body, thereby driving the climbing frame 4 to be lifted as a whole;

[0154] Step S40, when the climbing frame 4 climbs to the right position, the telescopic rod is extended downward to make the claw of the second claw assembly 4.2 fall above the outer claw shoe assembly 3.4 of the load-bearing member 3, and the climbing frame 4 is hung on the outside of the load-bearing member 3.

[0155] The jacking method proposed in the present invention has a convenient operation process. The support frame 5 is accommodated inside the climbing frame 4, and the two can be integrated and installed on one layer, thereby solving the problem that the existing self-lifting support system cannot be installed and lifted on the same structural layer. The construction steel platform 1 can be involved in the construction of the concrete main structure as early as possible, thereby improving the adaptability and construction efficiency of the construction steel platform 1 and shortening the construction period of the main structure.

[0156] The present invention further proposes a method for descending a same-layer frame mutual climbing self-lifting support system.

[0157] In this preferred embodiment, a descending method based on the above-mentioned same-layer frame mutual climbing self-elevating support system comprises the following steps:

[0158] Step S101, control the telescopic rod of the telescopic mechanism 6 to extend upward to drive the climbing frame 4 to rise, separate the claw of the second claw assembly 4.2 and the outer claw shoe assembly 3.4, rotate the claw of the second claw assembly 4.2 to store it inside the climbing frame 4 and then lock it, and control the telescopic rod to extend downward to drive the climbing frame 4 to descend;

[0159] Step S102, when the climbing frame 4 is lowered into position, the claws of the second claw assembly 4.2 are unlocked so that they are naturally extended to a horizontal state (the claws of the second claw assembly 4.2 are naturally in a horizontal state under gravity), and the telescopic rod is controlled to move so that the claws of the second claw assembly 4.2 fall above the outer claw shoe assembly 3.4;

[0160] Step S103, control the cylinder of the telescopic mechanism 6 to extend upward to separate the claw of the first claw assembly 3.3 and the inner claw shoe 5.1.1, rotate the claw of the first claw assembly 3.3 to be stored inside the load-bearing member 3 and then lock it, and control the cylinder to move downward to drive the support frame 5 to descend;

[0161] Step S104, when the support frame 5 is lowered into place, the claws of the first claw assembly 3.3 are unlocked to naturally extend to a horizontal state, and the cylinder body is controlled to move so that the claws of the first claw assembly 3.3 cooperate with the grooves of the inner claw boot 5.1.1, and the climbing frame 4 is hung on the outside of the load-bearing member 3.

[0162] The descending method of the same-layer frame inter-climbing self-lifting support system proposed in the present invention drives the construction steel platform 1 to descend through the support frame 5. On the one hand, it expands the types of construction operations (it can provide a working surface for secondary structure and exterior wall painting operations, etc.), and on the other hand, it facilitates the disassembly of the construction steel platform 1 from below (the construction steel platform 1 can follow the support frame 5 to descend to the bottom of the building instead of being disassembled at a high level as in the prior art).

[0163] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
