Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, and in particular to a super-high formwork with adjustable height. Background Art

[0002] At present, in the process of building construction, especially high-rise building construction, the ultra-high formwork support system has always been one of the important links. The traditional support system usually adopts a single pole or a simple multi-pole form. Although it can complete the basic support function, it is prone to deformation or even collapse at a high height, which not only increases safety hazards, but also limits the improvement of construction efficiency. With the advancement of building materials and technology, various forms of combined support systems have gradually appeared on the market. These new systems have improved the overall stability and bearing capacity to a certain extent.

[0003] There are some combined support systems in the prior art. For example, the invention patent with the publication number CN114135096A discloses a super-high structure formwork construction platform and its implementation method. The super-high structure formwork construction platform includes multiple lower vertical structures, each of which is provided with a high-altitude support, and multiple first Bailey groups are provided on the high-altitude support. The first Bailey group is provided with a second Bailey group, and a beam bottom construction platform is provided on the top surface of the second Bailey group. A conversion platform supported thereon is provided between adjacent second Bailey groups, a beam bottom formwork support is supported on the beam bottom construction platform, and a plate bottom formwork support is supported on the conversion platform. A beam-plate forming mold is provided on the top of the beam bottom formwork support and the plate bottom formwork support, and an upper beam plate is formed in the beam-plate forming mold. The super-high structure formwork construction platform uses the beam bottom construction platform and the conversion platform to form a reliable structural formwork system foundation at high altitude, which solves the problems of high construction cost, many unfavorable factors, and low construction efficiency in the prior art.

[0004] However, in the actual construction process, since the structures supporting the formwork are located on different columns, and the two structures are installed on the columns later, there will be height errors during installation, or the weight of the formwork is too heavy, causing the supporting structure at one end to sink, thereby causing the laying angle of the formwork to tilt, and affecting the subsequent construction of the beams. Therefore, the construction personnel are required to adjust the inclination angle of the formwork first. The current method for adjusting the formwork is to lift the formwork and reinstall the supporting structure. If the length of the formwork is too long, it cannot be lifted. Therefore, the existing formwork needs to be dismantled and the formwork needs to be re-laid. In summary, the existing method of adjusting the inclination angle of the formwork has a long construction period, which delays the construction progress. Summary of the invention

[0005] In view of the defects existing in the prior art, the technical problem solved by the present invention is: how to shorten the construction period required for adjusting the inclination angle of the formwork.

[0006] In order to achieve the above purpose, the present invention provides an ultra-high formwork with adjustable height, comprising: A first Bailey frame group, comprising four first Bailey frames, wherein the first Bailey frames are arranged around the pillars to form a rectangle; A second Bailey frame group, comprising a plurality of second Bailey frames horizontally laid in sequence, the second Bailey frame group being arranged between two adjacent columns, and the second Bailey frames at both ends of the second Bailey frame group being arranged on the first Bailey frame; An adjusting device is arranged on the top of two adjacent first Bailey frames. The adjusting device includes a main body, a first fixing component, a second fixing component and a height adjusting component. The main body is divided into a first part located between the first Bailey frame and the second Bailey frame, and a second part located on the top of another first Bailey frame. The first part and the second part of the main body are respectively provided with a first fixing component at the bottom, which is used to fix the main body to the two adjacent first Bailey frames respectively. A height adjusting component is provided on the top of the first part of the main body, and the height adjusting component is located at the bottom of the second Bailey frame. Push plates are provided on the two height adjusting components located at the bottom of the same second Bailey frame. The second Bailey frame is mounted on the push plate. A second fixing component is provided on the second part of the main body, which is used to fix the main body to the column.

[0007] By adopting the above technical scheme, the first Bailey frame group is fixed on the column, and an adjustment device is installed on the top of two adjacent first Bailey frames. The main body of the adjustment device is fixed to the two adjacent first Bailey frames respectively through the first fixing component, and the main body is connected to the column through the second fixing component. This design not only strengthens the stability between the two adjacent first Bailey frames, but also further strengthens the stability between the first Bailey frame group and the column, thereby reducing the probability of the supporting structure at one end sinking due to excessive weight of the formwork; a height adjustment component is provided on the top of the main body, and push plates are provided on the two height adjustment components located at the bottom of the same second Bailey frame. The height of the push plates can be adjusted by the height adjustment component, thereby adjusting the height of one end of the second Bailey frame group. Therefore, this design does not require the demolition and reconstruction of the structure to adjust the inclination angle of the formwork, thereby shortening the construction period required for adjusting the inclination angle of the formwork.

[0008] In one embodiment, a mounting groove is provided at the top of the main body, and a height adjustment assembly is arranged inside the mounting groove. The height adjustment assembly includes a driving motor, a threaded rod, a pushing block and a limiting track. The driving shaft of the driving motor is connected to one end of the threaded rod, and the threaded rod is located at the top of the driving motor. The driving motor is used to drive the threaded rod to rotate. The pushing block is sleeved on the other end of the threaded rod, and the inner wall of the pushing block is threadedly connected to the outer wall of the threaded rod. The pushing block is located inside the limiting track. The limiting track is vertically arranged inside the main body, and the pushing plate is arranged on the top of the pushing block.

[0009] By adopting the above technical solution, one end of the threaded rod is fixedly connected to the driving shaft of the driving motor, thereby causing the threaded rod to rotate. Since the inner wall of the push block is threadedly connected to the outer wall of the threaded rod, and the push block is located inside the limiting track, the rotation of the threaded rod drives the push block to move up or down along the limiting track, and the push block causes the push plate to move up or down. Therefore, the height of one end of the second Bailey frame group can be adjusted, and all the driving motors can be controlled by the same controller. Adjusting the inclination angle of the formwork only needs to be controlled by computer, and it is more accurate.

[0010] In one embodiment, the vertical surface of the inner wall of the pushing block is evenly divided into three parts: upper, middle and lower parts, and the lower part of the inner wall of the pushing block is a smooth surface.

[0011] By adopting the above technical solution, it is possible to avoid the push block moving upward too much, resulting in unstable support of the height-adjustable second Bailey frame, which may lead to construction safety accidents. Therefore, the lower part of the inner wall of the push block is not threaded, but a smooth surface is provided to ensure that after the threads of the threaded rod contact the smooth surface of the inner wall of the push block, the push block cannot move upward any further.

[0012] In one embodiment, a fixing groove is formed at the top of the first Bailey frame, and the first fixing assembly includes a latch and a limit block, the latch is arranged at the bottom of the main body, the limit block is sleeved on the latch, the latch is inserted into the inside of the fixing groove, and the limit block is used to abut against the inner wall of the fixing groove.

[0013] By adopting the above technical solution, the main body is fixed to the position where the fixing groove is provided in the first Bailey frame by means of the latch and the limit block.

[0014] In one embodiment, a limit plate is provided on the inner wall of the fixing groove, and a self-locking spring is provided at the bottom of the latch, and the self-locking spring is used to abut against the bottom surface of the limit plate.

[0015] By adopting the above technical solution, during the insertion of the pin, the self-locking retaining spring abuts against the side of the limit plate, so the pin can still be inserted downward; when the position of the self-locking retaining spring exceeds the position of the limit plate, the self-locking retaining spring opens and abuts against the bottom surface of the limit plate, so the pin is difficult to pull out, thereby further improving the stability between the adjustment device and the first Bailey frame assembly.

[0016] In one embodiment, the limiting plate is a whole, which is arranged around the inner wall of the fixing groove; Alternatively, the limiting plates are multiple and are evenly distributed on the inner wall of the fixing groove.

[0017] By adopting the above technical solution, it is avoided that after the self-locking spring is opened, some structures have no force points, causing the pin to fall off from the fixing groove, thereby further improving the stability between the adjustment device and the first Bailey frame assembly.

[0018] In one embodiment, the second fixing component has the same structure as the first fixing component.

[0019] By adopting the above technical solution, a horizontal groove is opened on the column, and the above structure is inserted into the groove opened on the column in a horizontal direction, so that the adjustment device is fixed to the column.

[0020] In one embodiment, a Bailey frame connecting plate is sleeved on the top of the column, the truss connecting plate is fixedly connected to the column by anchor nails, and the truss connecting plate is fixedly connected to the second Bailey frame by a connecting assembly.

[0021] By adopting the above technical solution, the second Bailey frame is not directly fixedly connected to the column by anchor nails, thereby avoiding excessive load on a certain point of the column at the connection between the two, resulting in adverse effects on the quality of the column.

[0022] In one embodiment, the connecting assembly includes a connecting member and a hook group, the connecting member is arranged on a surface of the second Bailey frame close to the truss connecting plate, and the hook group includes hooks arranged sequentially on the truss connecting plate along the vertical direction, and one of the hooks is detachably connected to the connecting member.

[0023] By adopting the above technical solution, in the process of pushing the second Bailey frame through the height adjustment component, the second Bailey frame and the column perform relative movement in the vertical direction. Therefore, fixing the second Bailey frame and the column through anchor nails cannot meet the needs. Therefore, multiple hooks are arranged in the vertical direction on the truss connecting plate. After the pushing is completed, a suitable hook is selected to connect with the connecting piece on the second Bailey frame.

[0024] In one embodiment, a support platform is sleeved on the column, the support platform is fixed to the column by bolts, the support platform is located at the bottom of the first Bailey frame group, and the support platform is used to support the first Bailey frame group; The support platform includes four L-shaped standard sections and four connecting sections. The L-shaped standard sections are arranged at the corners of the columns, and connecting sections are arranged between two adjacent L-shaped standard sections. A construction platform is arranged on the periphery of the support platform, and a guardrail is arranged around the construction platform.

[0025] By adopting the above technical solution, the top of the supporting platform is offset against the bottom of the first Bailey frame group, so as to further improve the stability between the first Bailey frame group and the column, thereby further reducing the probability of the supporting structure sinking; the four sections of L-shaped standard sections are unchanged, and only need to be installed on the corners of the column. The appropriate size is selected from the connecting sections of different sizes and installed between two adjacent L-shaped standard sections to form a whole. Therefore, the supporting platform can be applied to columns of different sizes; in the process of installing the formwork, the construction workers are required to fix the formwork at high altitude. In order to avoid the construction workers being in a suspended state for a long time and performing high-altitude operations, a construction platform is set on the periphery of the supporting platform, and the construction workers can stand on the construction platform to perform operations.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects: 1. The height of the push plate is adjusted through the height adjustment assembly, thereby adjusting the height of one end of the second Bailey frame. Therefore, this design does not require the demolition and reconstruction of the structure to adjust the inclination angle of the formwork, thereby shortening the construction period required for adjusting the inclination angle of the formwork; 2. The adjusting device fixes the first Bailey frames and the first Bailey frames and the columns, further improving the stability between the first Bailey frame group and the columns; 3. A construction platform is set up outside the supporting platform, and construction workers can stand on the construction platform to work, avoiding long-term work suspended in the air, thereby improving construction safety.

DETAILED DESCRIPTION

[0029] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0030] The height-adjustable super-high formwork in the embodiment of the present invention is shown in FIG. Figure 1 , 2 As shown, the height-adjustable super-high formwork includes a first Bailey frame group, which includes four first Bailey frames 1. The first Bailey frames 1 are used to be arranged around the columns 3. The structure formed by splicing the first Bailey frames 1 is a rectangular cross-section in top view; A second Bailey frame group, comprising a plurality of second Bailey frames 2 horizontally laid in sequence, one end of a second Bailey frame 2 being connected to one end of another second Bailey frame 2, the second Bailey frame group being arranged between two adjacent columns 3, and the second Bailey frames 2 at both ends of the second Bailey frame group being arranged on the first Bailey frame 1, if the number of the columns 3 is 2, then the number of the second Bailey frame group is 1, if the number of the columns 3 is 3, then the number of the second Bailey frame group is 2, and so on; An adjusting device 4 is commonly provided on the tops of two adjacent first Bailey frames 1, and the adjusting device 4 includes a main body 401, a first fixing component, a second fixing component and a height adjusting component. The main body 401 is divided into a first part located between the first Bailey frame 1 and the second Bailey frame 2, and a second part located on the top of another first Bailey frame 1. The upright projection surface of the second Bailey frame 2 at the end is located on the first Bailey frame 1 of the first part. The first fixing components are respectively provided on the bottoms of the first and second parts of the main body 401, which are used to fix the main body 401 to the two adjacent first Bailey frames 1 respectively. A height adjusting component is provided on the top of the first part of the main body 401, and the height adjusting component is located at the bottom of the second Bailey frame 2. A pushing plate 5 is provided on the two height adjusting components located at the bottom of the same second Bailey frame 2. The second Bailey frame 2 is mounted on the pushing plate 5, that is, the two height adjusting components act on one pushing plate 5 together. A second fixing component is provided on the second part of the main body 401, which is used to fix the main body 401 to the column 3.

[0031] It can be seen that the present invention fixes the first Bailey frame group at the design height of the column 3, the first Bailey frame group is sleeved on the column 3, two adjacent first Bailey frames 1 have intersections, and an adjustment device 4 is commonly installed on the top of the two adjacent first Bailey frames 1, that is, the adjustment device 4 is located at the intersection, and the main body 401 of the adjustment device 4 is respectively fixed to the two adjacent first Bailey frames 1 through the first fixing component, and the main body 401 is connected to the column 3 through the second fixing component. This design not only strengthens the stability between the two adjacent first Bailey frames 1, but also further strengthens the stability between the first Bailey frame group and the column 3, thereby reducing the probability of the support structure at one end sinking due to excessive weight of the formwork; A height adjustment component is provided at the top of the first part of the main body 401, and a push plate 5 is provided on the two height adjustment components located at the bottom of the same second Bailey frame 2. The height of the push plate 5 can be adjusted by the height adjustment component. Since the push plate 5 pushes the second Bailey frame 2 at the end, the height of the second Bailey frame 2 is adjusted, thereby adjusting the inclination angle of the second Bailey frame group, that is, the formwork. Therefore, this design does not require the demolition and reconstruction of the structure to adjust the inclination angle of the formwork, thereby shortening the construction period required for adjusting the inclination angle of the formwork.

[0032] Preferably, see Figure 3 As shown, a specific structure of a height adjustment component is provided: A mounting groove is provided at the top of the main body 401, and a height adjustment component is arranged inside the mounting groove. The height adjustment component includes a driving motor 402, a threaded rod 403, a pushing block 405 and a limiting track 404. The driving shaft of the driving motor 402 is connected to one end of the threaded rod 403, and the threaded rod 403 is located at the top of the driving motor 402. The driving motor 402 is used to drive the threaded rod 403 to rotate. The pushing block 405 is sleeved on the other end of the threaded rod 403. The pushing block 405 is U-shaped, and the closed end of the pushing block 405 is located at the top of the threaded rod 403. The inner wall of the pushing block 405 is threadedly connected to the outer wall of the threaded rod 403. The pushing block 405 is located inside the limiting track 404. The limiting track 404 is vertically arranged inside the main body 401, and the pushing plate 5 is arranged on the top of the pushing block 405.

[0033] Specifically, one end of the threaded rod 403 is fixedly connected to the driving shaft of the driving motor 402, so the driving motor 402 works to make the threaded rod 403 rotate, and the threaded rod 403 can rotate forward or reverse. Because the inner wall of the push block 405 is threadedly connected to the outer wall of the threaded rod 403, and the push block 405 is located inside the limiting track 404, the limiting track 404 limits the push block 405, and the push block 405 cannot rotate, but moves up or down. Therefore, the rotation of the threaded rod 403 drives the push block 405 to move up or down along the limiting track 404, and the push block 405 makes the push plate 5 move up or down, so the height of one end of the second Bailey frame group can be adjusted, and all the driving motors 402 can be controlled by the same controller. The inclination angle of the formwork only needs to be adjusted by computer control, and it is more accurate. If the second Bailey frame 2 at the end is inclined to the surface perpendicular to the second Bailey frame group, it can also be adjusted by controlling a height adjustment component.

[0034] For further information, see Figure 3 As shown, the vertical surface of the inner wall of the push block 405 is evenly divided into three parts: upper, middle and lower. The lower part of the inner wall of the push block 405 is a smooth surface, and the length of the smooth surface can be designed according to actual needs.

[0035] Specifically, in order to avoid the push block 405 moving upward too much, resulting in unstable support of the height adjustable second Bailey frame 2, which may lead to construction safety accidents, the lower part of the inner wall of the push block 405 is not threaded, but a smooth surface is provided to ensure that after the thread of the threaded rod 403 contacts the smooth surface of the inner wall of the push block 405, the push block 405 cannot continue to move upward. The adjustable height of the push block 405 is determined by calculation, that is, the adjustable height range of the push block is guaranteed under the premise of ensuring construction safety, and the smooth surface is designed in this way. Of course, a limit piece can also be provided on the inner wall of the push block 405, and a corresponding limit piece is also designed on the threaded rod 403. When the push block 405 rises to a certain height, the limit piece of the push block 405 is offset against the limit piece of the threaded rod 403, thereby achieving the effect that the push block 405 cannot continue to move upward. The specific position of the limit piece design can also be designed according to actual needs.

[0036] Preferably, see Figure 4 As shown, a specific structure of a first fixing component is provided: A fixing groove 301 is provided at the top of the first Bailey frame 1, and the first fixing component includes a latch 406 and a limit block 407. The latch 406 is arranged at the bottom of the main body 401, and the limit block 407 is sleeved on the latch 406. The limit block 407 can be arranged in the middle of the latch 406 or at the top of the latch 406, that is, the limit block 407 is fixed to the latch 406 and the bottom surface of the main body 401 at the same time. The shape of the limit block 407 can be an inverted triangle, which becomes wider from bottom to top. The latch 406 is inserted into the inside of the fixing groove 301, and the limit block 407 is used to abut against the inner wall of the fixing groove 301.

[0037] Specifically, when fixing the main body 401 to the first Bailey frame 1, the pin 406 of the first fixing group is inserted downward into the interior of the fixing groove 301. When the pin 406 moves downward to a certain distance, the limit block 407 on the pin 406 will be engaged between the pin 406 and the fixing groove 301, and the pin 406 cannot continue to move downward, thereby achieving a fixing effect.

[0038] Furthermore, a limiting plate 302 is disposed on the inner wall of the fixing groove 301 , and a self-locking retaining spring 408 is disposed at the bottom of the latch 406 . The self-locking retaining spring 408 is used to abut against the bottom surface of the limiting plate 302 .

[0039] Specifically, during the insertion of the latch 406, the self-locking retaining spring 408 abuts against the side of the limit plate 302, so the latch 406 can still be inserted downward. When the position of the self-locking retaining spring 408 exceeds the position of the limit plate 302, the self-locking retaining spring 408 opens and abuts against the bottom surface of the limit plate 302, so the latch 406 is difficult to pull out, thereby further improving the stability between the adjustment device 4 and the first Bailey frame assembly.

[0040] Furthermore, the limiting plate 302 is a whole, which is disposed around the inner wall of the fixing groove 301; Alternatively, there are multiple limiting plates 302 , which are evenly distributed on the inner wall of the fixing groove 301 .

[0041] Specifically, the limit plate 302 is arranged on the inner wall of the fixing groove 301, and can be designed as a continuous ring or a discontinuous ring. It only needs to ensure that after the self-locking spring 408 is opened, the self-locking spring 408 and the limit plate 302 are evenly stressed, and the structure of the self-locking spring 408 is stressed on the limit plate 302, thereby preventing the pin 406 from falling off from the fixing groove 301, thereby further improving the stability between the adjustment device 4 and the first Bailey frame assembly.

[0042] Preferably, the second fixing component has the same structure as the first fixing component.

[0043] Specifically, a horizontal groove is opened on the column 3, and the pin 406 of the second fixing component is horizontally inserted into the groove opened on the column 3. When the pin 406 moves horizontally to a certain distance, the limit block 407 on the pin 406 will be engaged between the pin 406 and the fixing groove 301, and the pin 406 cannot continue to move in the insertion direction, thereby fixing the adjustment device 4 to the column 3.

[0044] It is understandable that the structure of the second fixing assembly may be different from that of the first fixing assembly. The second fixing assembly may be designed as a bolt assembly, and the main body 401 is fixed to the column 3 by the bolt assembly.

[0045] Combining the designs of the first fixing assembly and the second fixing assembly, not only the adjusting device 4 is fixed to the first Bailey frame group, but also the stability between two adjacent first Bailey frames 1 is strengthened, and the stability between the first Bailey frame group and the column 3 is further strengthened, thereby reducing the probability of the supporting structure at one end sinking due to excessive weight of the formwork.

[0046] Preferably, a Bailey frame connecting plate is sleeved on the top of the column 3, and the truss connecting plate is fixedly connected to the column 3 by anchor nails. The truss connecting plate can be connected to the column 3 on one side or on multiple sides, and the truss connecting plate is fixedly connected to the second Bailey frame 2 by a connecting assembly.

[0047] Specifically, the second Bailey frame 2 is not directly fixedly connected to the column 3 by anchor nails, so as to avoid excessive load on a certain point of the column 3 at the connection between the two, resulting in adverse effects on the quality of the column 3. However, the above design can connect multiple surfaces of the truss connecting plate to the column 3 together, so that multiple surfaces of the column 3 are subjected to force at the same time, thereby avoiding excessive load on a certain point of the column 3 at the connection between the two.

[0048] Furthermore, the connecting component includes a connecting piece and a hook group. The connecting piece is arranged on a side of the second Bailey frame 2 close to the truss connecting plate. The hook group includes hooks arranged on the truss connecting plate in sequence along the vertical direction. One of the hooks is detachably connected to the connecting piece. The number of connecting pieces and a row of hooks can be set according to actual conditions. The heavier the weight of the second Bailey frame group, the more numbers are required, and the vertical movement of one end of the second Bailey frame group will not be too much. Therefore, the spacing between the hooks in different rows can be set relatively closely. The specific design is still based on actual conditions.

[0049] Specifically, in the process of pushing the second Bailey frame through the height adjustment assembly, the second Bailey frame and the column perform relative movement in the vertical direction. Therefore, fixing the second Bailey frame and the column through anchor nails cannot meet the needs. Therefore, multiple hooks are set in the vertical direction on the truss connecting plate. After the pushing is completed, a suitable hook is selected to connect with the connecting piece on the second Bailey frame.

[0050] Preferably, see Figure 1 , 2 As shown in Figures 5 and 6, a support platform 6 is mounted on the column 3, and the support platform 6 is fixed to the column 3 by bolts. The support platform 6 is located at the bottom of the first Bailey frame group, and is used to support the first Bailey frame group. The support platform 6 also has four platforms, and the structure formed by splicing is a rectangular cross-section in top view, and a first Bailey frame 1 is supported on one platform.

[0051] Specifically, in order to further improve the stability between the first Bailey frame group and the column 3 and further reduce the probability of the supporting structure sinking, the first Bailey frame group is built with a support platform 6 at the bottom of the first Bailey frame group on the basis of the above-mentioned fixed design, which is used to further provide support for the first Bailey frame group.

[0052] Furthermore, the supporting platform 6 includes four sections of L-shaped standard sections 601 and four sections of connecting sections 602 . The L-shaped standard sections 601 are arranged at the corners of the columns 3 , and a connecting section 602 is arranged between two adjacent L-shaped standard sections 601 .

[0053] Specifically, the L-shaped standard section 601 and the connecting section 602 can be Bailey frames or other steel structures. When designing the four-section L-shaped standard section 601, only one size needs to be designed. First, the four-section L-shaped standard section 601 is installed on the corner of the column 3, and then the appropriate size is selected from the connecting sections 602 of different sizes and installed between two adjacent L-shaped standard sections 601 to form a whole. Therefore, the support platform 6 can be applied to columns 3 of different sizes, which improves the applicability of the support platform 6 and saves the cost of the steel structure.

[0054] Furthermore, a construction platform 603 is arranged on the periphery of the supporting platform 6 , and a guardrail 7 is arranged around the construction platform 603 .

[0055] Specifically, during the process of formwork installation, construction workers are required to fix the formwork at high altitude. In order to avoid the construction workers being in a suspended state for a long time and performing high-altitude operations, a construction platform 603 is set outside the support platform 6, and the construction workers can stand on the construction platform 603 to perform operations.

[0056] The above description is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest range consistent with the principles and novel features applied for herein.
