Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to a formwork support system for ultra-high-rise composite slabs and its application method. Background Technology

[0002] The composite slab formwork support system for super high-rise buildings refers to the support system used to support the composite slab formwork of super high-rise buildings. Composite slabs are a type of precast concrete slab, which is convenient to construct and highly controllable, and can be used for the construction of floor slabs and wall panels in high-rise and super high-rise buildings.

[0003] A search revealed Chinese patent publication number CN213952973U, which discloses a composite slab support structure, comprising: a composite slab, a wall template to be poured, and a support device. The support device is disposed at the bottom of the composite slab and provides temporary support for the composite slab. The composite slab has several pre-embedded sleeves at positions corresponding to the support device. The pre-embedded sleeves are connected to the top of the support device by bolts. The support device is disposed on the foundation. Both ends of the composite slab are provided with wall templates to be poured. The wall templates to be poured enclose the pouring space of the wall. After the wall is poured, it forms a support structure for the composite slab.

[0004] The aforementioned patent has the following shortcomings: its support device adopts an integral structure. When supporting the composite slabs of super high-rise buildings, due to the high support height, the length of the corresponding support device is also high, resulting in a large size, which makes its processing, transportation and installation more difficult.

[0005] Therefore, this invention proposes a support system for ultra-high-rise composite slab formwork and its application method. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a support system for ultra-high-rise composite slab formwork and its application method.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A formwork support system for ultra-high-rise composite slabs includes fixed support members for fixed support of the composite slabs and movable support columns for temporary support of the composite slabs. The fixed support consists of side beams at both ends, multiple intermediate beams in the middle, and multiple crossbeams between the side beams and the intermediate beams and between adjacent intermediate beams, and the intermediate beams, side beams and crossbeams form a grid structure. The movable support column includes an adjustable support at the bottom, a locking assembly at the top, and multiple connecting sections connected between the adjustable support and the locking assembly. Adjacent connecting sections, as well as connecting sections to the adjustable support and connecting sections to the locking assembly, are all connected by flanges.

[0008] Preferably, the middle beam has waist-shaped holes on both sides and the inner sidewalls of the side beams, and the crossbeam is fixed to the waist-shaped holes through the fixing holes at both ends.

[0009] Furthermore, adjustable mounting components are provided at both ends of the intermediate beam. The adjustable mounting components include angle steel two fixedly installed on the outer wall of the bottom of the intermediate beam and angle steel one movably inserted into the inner wall of angle steel two. An installation hole is provided on the inner wall of angle steel one.

[0010] Based on the aforementioned scheme: the locking assembly includes a limiting seat and a limiting cylinder fixedly installed at the bottom of the fixed support. The radial inner wall of the limiting seat is slidably fitted with multiple limiting posts, and the axial inner wall of the limiting seat is slidably fitted with a protruding post. A wedge is fixedly installed on the bottom outer wall of the protruding post, and the wedge is engaged with the side wall of the limiting post through an inclined surface.

[0011] A better option among the aforementioned solutions is that the inner side of the limiting cylinder is provided with a longitudinal groove, and the outer side of the limiting post is provided with a limiting seat that matches the longitudinal groove.

[0012] As a further embodiment of the present invention: the adjustable support includes a base and a fixing ring fixedly installed on the top outer wall of the base. The inner wall of the fixing ring is movably fitted with a sliding column. A jack is fixedly installed on the top outer wall of the base inside the fixing ring. The telescopic end of the jack contacts and fits with the sliding column.

[0013] Meanwhile, the side wall of the fixing ring is connected to a screw rod by a thread, one end of the screw rod is rotatably connected to a locking block, and the other end of the screw rod is fixedly connected to a handle.

[0014] As a preferred embodiment of the present invention, both the outer wall of the sliding column and the inner wall of the locking block are provided with transverse grooves.

[0015] Meanwhile, the bottom outer wall of the base has multiple countersunk grooves, the inner wall of the countersunk grooves accommodates a support block, the top of the support block is rotatably connected to a screw rod, the screw rod is connected to the inner wall of the base through a thread on its outer wall, and a connecting block is fixedly installed on the top of the screw rod, with handles rotatably connected to both ends of the connecting block.

[0016] As a preferred embodiment of the present invention, a reinforcing rib is fixedly installed on the opposite side of the base and the fixing ring.

[0017] The beneficial effects of this invention are as follows: 1. The present invention sets the movable support column as an adjustable support, a locking component and multiple connecting sections, so that the entire movable support column can be divided into multiple smaller units, making the relative volume of each unit smaller, thereby making processing, transportation and installation more convenient, and the support height can be controlled by controlling the number of connecting sections.

[0018] 2. This invention further realizes modularization by setting the fixed support as a combination of middle beam, side beam and cross beam, thereby increasing construction efficiency. In addition, by using waist-shaped holes and fixing holes to fix the cross beam, the installation position has a certain redundancy, which can provide a certain compensation space for the installation of the entire fixed support and the size of the composite slab during prefabrication, ensuring the fit of the entire structure installation and thus increasing the stability of the structure.

[0019] 3. This invention, by setting an adjustable installation component, utilizes the movable limit of angle steel two against angle steel one, and then utilizes the movement of angle steel one to achieve compensation in the installation length of the intermediate beam, thereby enabling targeted adjustment according to the specific distance between the two walls, further increasing the convenience of construction.

[0020] 4. This invention, by setting a locking component, utilizes the mutual friction between the limiting post and the limiting cylinder to achieve mutual rotational limiting between the limiting cylinder and the limiting seat, thereby preventing the entire fixed support structure from being deformed by torsional force, increasing the stability of the support, and using the protruding post for driving, so that the support is automatically limited during support and automatically released during disassembly, further increasing the convenience of construction.

[0021] 5. This invention, by setting the adjustable support as a combination of a fixed ring and a sliding column, and by using a jack to adjust the height of the sliding column, can achieve fine adjustment of the support height, thus ensuring the reliability of the support. In addition, by setting a locking block and horizontal grooves, the sliding column and the fixed ring can be locked after the height is adjusted, which can prevent damage to the jack caused by long-term pressure and increase its service life.

[0022] 6. By setting up support blocks and screw rods, when the movable support column is used on uneven ground, the position of the support blocks can be adjusted to make the base level, thereby increasing the stability of the support. In addition, by setting up a handle, it can achieve the effect of saving effort and can also hang down for storage when not in use. Attached Figure Description

Detailed Implementation

[0025] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0026] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example

[0027] A formwork support system for ultra-high-rise composite slabs, such as Figure 1-9 As shown, it includes a fixed support member 1 for fixed support of the composite slab and a movable support column 2 for temporary support of the composite slab.

[0028] The fixed support 1 consists of side beams 5 at both ends, multiple intermediate beams 4 in the middle, and multiple crossbeams 6 between the side beams 5 and the intermediate beams 4 and between adjacent intermediate beams 4, and the intermediate beams 4, side beams 5 and crossbeams 6 form a grid structure.

[0029] The movable support column 2 includes an adjustable support 12 at the bottom, a locking assembly 15 at the top, and multiple connecting sections 14 connected between the adjustable support 12 and the locking assembly 15. Adjacent connecting sections 14, as well as connecting sections 14 to the adjustable support 12 and the locking assembly 15, are all connected by flanges 13.

[0030] This device, by setting the movable support column 2 as a combination of an adjustable support 12, a locking assembly 15 and multiple connecting sections 14, allows the entire movable support column 2 to be divided into multiple smaller units, making the relative volume of each unit smaller, thus making processing, transportation and installation more convenient, and the support height can also be controlled by controlling the number of connecting sections 14.

[0031] To solve the problem of fixed limit; such as Figure 2 As shown, waist-shaped holes 7 are provided on both sides of the middle beam 4 and on the inner side wall of the side beam 5. The crossbeam 6 is fixed to the waist-shaped holes 7 through the fixing holes 8 at both ends.

[0032] This device further achieves modular disassembly by setting the fixed support 1 as a combination of the middle beam 4, the side beams 5 and the crossbeam 6, thereby increasing construction efficiency. In addition, the crossbeam 6 is fixed by using the waist-shaped hole 7 and the fixing hole 8, which gives its installation position a certain redundancy. This provides a certain compensation space for the installation of the entire fixed support 1 and the dimensions during the prefabrication of the composite slab, ensuring the fit of the entire structure installation and thus increasing the stability of the structure.

[0033] To address the convenience issue; such as Figure 1 , 3 As shown, adjustable mounting components 3 are provided at both ends of the intermediate beam 4. The adjustable mounting components 3 include angle steel 2 11 welded to the bottom outer wall of the intermediate beam 4 and angle steel 1 10 movably inserted into the inner wall of angle steel 2 11. The inner wall of angle steel 10 is provided with mounting holes 9.

[0034] When installing the intermediate beam 4, bolts can be used to fix it to the building wall through the mounting hole 9. After fixing, angle steel 10 and angle steel 21 can be welded together or angle steel 10 can be welded together with the intermediate beam 4.

[0035] This device, by setting an adjustable installation component 3, uses angle steel 2 11 to limit the movement of angle steel 10, and then uses the movement of angle steel 10 to compensate for the installation length of the intermediate beam 4, thereby enabling targeted adjustment according to the specific distance between the two walls, further increasing the convenience of construction.

[0036] To address the issue of support stability; such as Figure 4 , 5As shown in Figure 6, the locking assembly 15 includes a limiting seat 19 and a limiting cylinder 16 welded to the bottom of the fixed support member 1. The radial inner wall of the limiting seat 19 is slidably fitted with a plurality of limiting posts 21, and the axial inner wall of the limiting seat 19 is slidably fitted with a protruding post 18. The bottom outer wall of the protruding post 18 is welded with a wedge 22, and the wedge 22 is fitted to the side wall of the limiting post 21 through the inclined surface 23.

[0037] Furthermore, the inner side of the limiting cylinder 16 is provided with longitudinal groove 17, and the outer side of the limiting post 21 is provided with a limiting seat 19 that matches the longitudinal groove 17.

[0038] In use, when the limiting seat 19 provides support to the limiting cylinder 16, the protruding post 18 first contacts the inner wall of the limiting cylinder 16. At the same time, the protruding post 18 is subjected to the downward reaction force of the limiting cylinder 16. The protruding post 18 transmits the force to the wedge block 22, and then pushes the limiting post 21 outward through the inclined surface 23, so that the limiting post 21 and the limiting cylinder 16 come into contact with each other. The longitudinal groove 17 and the longitudinal groove 20 are used to achieve mutual rotational limitation between the limiting cylinder 16 and the limiting seat 19, thereby preventing the entire fixed support 1 structure from being deformed by torsional force.

[0039] This device, by setting a locking component 15, utilizes the mutual friction between the limiting post 21 and the limiting cylinder 16 to achieve mutual rotational limitation between the limiting cylinder 16 and the limiting seat 19, thereby preventing the entire fixed support 1 structure from being deformed by torsional force, increasing the stability of the support, and using the protruding post 18 for driving, can automatically limit the position during support and automatically release it during disassembly, further increasing the convenience of construction.

[0040] To address the issue of fine-tuning the support height; such as Figure 7 As shown, the adjustable support 12 includes a base 24 and a fixing ring 26 welded to the top outer wall of the base 24. A sliding column 27 is movably fitted on the inner wall of the fixing ring 26. A jack 28 is fixedly installed on the top outer wall of the base 24 inside the fixing ring 26. The telescopic end of the jack 28 contacts and fits with the sliding column 27.

[0041] In this embodiment, the specific type of jack 28 is not limited. It can be a manual hydraulic jack or an electric hydraulic jack. Since multiple movable support columns 2 need to be arranged, electric drives are difficult to arrange and have high costs. Therefore, in this embodiment, a manual hydraulic jack is preferred.

[0042] The height of the sliding column 27 can be adjusted by using the jack 28, thereby adjusting the support height and support force.

[0043] The side wall of the fixing ring 26 is connected to a screw rod 31 by a thread. One end of the screw rod 31 is rotatably connected to a locking block 32, and the other end of the screw rod 31 is fixedly connected to a handle 30. The outer side wall of the sliding column 27 and the inner side wall of the locking block 32 are both provided with horizontal lines 29.

[0044] Once the required support height is reached, the handle 30 can be turned to move the locking block 32 closer to the sliding post 27, thereby using the cross groove 29 to lock the sliding post 27 and the fixing ring 26.

[0045] This device, by setting the adjustable support 12 as a combination of a fixed ring 26 and a sliding column 27, and by using a jack 28 to adjust the height of the sliding column 27, can achieve fine adjustment of the support height, ensuring the reliability of the support. In addition, by setting a locking block 32 and a cross stripe 29, the sliding column 27 and the fixed ring 26 can be locked after the height is adjusted, which can prevent the jack 28 from being damaged by long-term pressure and increase its service life.

[0046] To solve the stability problem, such as Figure 9 As shown, the bottom outer wall of the base 24 is provided with multiple countersunk grooves 33, the inner wall of the countersunk grooves 33 accommodates a support block 34, the top of the support block 34 is rotatably connected to a screw 35, the screw 35 is connected to the inner wall of the base 24 through a thread provided on its outer wall, and a connecting block 36 is welded to the top of the screw 35, and handles 37 are rotatably connected to both ends of the connecting block 36.

[0047] By setting up support block 34 and screw 35, when the movable support column 2 is used on uneven ground, the position of support block 34 can be adjusted to make the base 24 level, thereby increasing the stability of the support. Furthermore, by setting up handle 37, it can achieve the effect of saving effort and can also hang down for storage when not in use.

[0048] A reinforcing rib 25 is welded to the opposite side of the base 24 and the fixing ring 26. Example

[0049] A method for using a formwork support system for ultra-high-rise composite slabs, such as... Figure 1-9 The process includes the following steps: S1: Installation of fixed support component 1; S11: First, install the side beam 5 on the wall, and then use the adjustable mounting assembly 3 to install multiple intermediate beams 4 at equal intervals between the side beams 5. S12: Next, install the crossbeam 6 between the middle beam 4 and the side beam 5, as well as between the middle beam 4 and the middle beam 4, and ensure that the grid size is consistent; S2: Support of movable support column 2; S21: Select the number of connecting sections 14 to be used according to the height of the support, and install the connecting sections 14 step by step; S22: Next, install the locking assembly 15 to the top of the uppermost connecting section 14, and then place the limit seat 19 below the limit cylinder 16; S23: Operate jack 28 to raise the movable support column 2 as a whole until the limit seat 19 is inserted into the limit cylinder 16 and the limit column 21 contacts the inner wall of the limit cylinder 16. S24: Then rotate the handle 30 so that the locking block 32 fits into the sliding post 27, thus locking the sliding post 27 into the fixing ring 26.
