Description

Technical Field

[0001] This utility model belongs to the technical field of high-altitude connecting beam formwork support structure, specifically relating to a formwork support frame for high-altitude connecting beams. Background Technology

[0002] The use of traditional ground-mounted scaffolding for high-altitude cantilever structures presents challenges such as large workload, complex force transmission paths, excessively long construction periods, and significant safety risks due to the height of the scaffolding. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a formwork support frame for high-altitude connecting beams, thereby reducing the amount of work and cost, shortening the construction period, and reducing construction risks.

[0004] The technical solution adopted in this utility model is as follows: a template support frame for high-altitude connecting beams, comprising multiple uprights, multiple horizontal trusses, and a support platform. The support platform is detachably and fixedly connected to the walls on both sides. The lower ends of the multiple uprights are fixedly connected to the support platform, and the multiple horizontal trusses are vertically and spaced apart and fixedly connected to the multiple uprights. The support platform includes multiple longitudinal support beams arranged horizontally at intervals. The two ends of the multiple longitudinal support beams are respectively fixedly overlapped on two end transverse support beams. The two ends of the two end transverse support beams are respectively fixedly overlapped on two longitudinal double-end cantilever beams. The two longitudinal double-end cantilever beams are respectively longitudinally movable through the longitudinal reserved holes in the walls on both sides and locked with longitudinal wedges. The bottom surface of the longitudinal reserved hole is flush with the top surface of the first floor slab under the connecting beam.

[0005] Furthermore, the aforementioned support platform also includes multiple intermediate transverse support beams. The two ends of the multiple intermediate transverse support beams respectively move laterally through the transverse reserved holes in the two side walls and are locked together with transverse wedges. The upper side of the multiple intermediate transverse support beams is fixedly connected to multiple longitudinal support beams.

[0006] Furthermore, each of the aforementioned intermediate transverse support beams is provided with a figure-eight shaped diagonal brace at its bottom. The upper end of the diagonal brace is fixedly connected to the intermediate transverse support beam, and the lower end is fixedly connected to the pre-embedded steel plate on the wall surface.

[0007] Furthermore, the aforementioned embedded steel plate is provided with anchoring steel bars that are fixedly connected to it, and the anchoring steel bars are fixedly connected to the wall steel bars inside the wall.

[0008] Furthermore, the aforementioned diagonal brace is welded and fixed to the embedded steel plate, and the embedded steel plate is fixedly connected to a limit strip, which is located at the bottom of the welding point between the diagonal brace and the embedded steel plate and abuts against the diagonal brace.

[0009] Furthermore, the aforementioned formwork support frame for high-altitude connecting beams also includes an operating platform installed two floors below the connecting beams. The operating platform includes multiple H-beams, steel plates, and end transverse H-beams. The steel plates are fixedly connected to the top surfaces of the multiple longitudinal H-beams. The two ends of the multiple longitudinal H-beams overlap with the two end transverse H-beams. The two end transverse H-beams overlap with the two longitudinal double-headed cantilever H-beams. The two longitudinal double-headed cantilever H-beams respectively move through the two longitudinal pre-drilled holes in the two side walls and are locked with longitudinal wedges.

[0010] Furthermore, the aforementioned operating platform also includes multiple intermediate transverse H-beams, with both ends of the multiple intermediate transverse H-beams passing through the transverse pre-drilled holes on both sides of the wall and locked in place by two wedges. The upper sides of the multiple intermediate transverse H-beams are fixedly connected to multiple longitudinal H-beams.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] (1) Compared with traditional full-span scaffolding, the use of detachable formwork support frames to form a suspended high formwork system can make full use of the building structure’s own bearing capacity, save on foundation reinforcement materials and scaffolding usage, and has a high recycling rate of steel for support and I-beam platforms. It is economical and reasonable. The formwork support frames can be detachably erected using pre-reserved holes, which greatly reduces the amount of work, lowers costs, shortens the construction period, and is highly safe. It is especially beneficial for 31-story high-rise buildings.

[0013] (2) The longitudinal double-end cantilever beam and the middle transverse support beam are installed by using the longitudinal pre-reserved hole one and the transverse pre-reserved hole one respectively. The installation and dismantling are convenient and quick, and the support is stable and reliable. The support platform skeleton is composed of the longitudinal double-end cantilever beam, the middle transverse support beam, the longitudinal support beam and the end transverse support beam. The support strength and rigidity are good, and the support stability is high. It can ensure the stable casting of the connecting beam and avoid sinking, which would lead to a decrease in the reliability of the connection with the walls on both sides.

[0014] (3) The figure-eight angle steel bracing can reinforce the longitudinal support beam. By pre-embedding steel plates on the wall surface and welding them with the bracing, the support points on the wall surface are more stable and the connection is more reliable, avoiding damage to the wall surface that could cause the connection points to fall off.

[0015] (4) Anchor steel bars are set in the embedded steel plate to improve the stability and reliability of the connection between the embedded steel plate and the wall surface, avoid the slippage due to excessive force, and improve the support reliability of the diagonal brace;

[0016] (5) Setting a limit bar can prevent the diagonal brace from slipping down after welding off and becoming loose, thus improving the reliability of the connection;

[0017] (6) Setting up a template frame and tie rods can prevent grout bursting in the side templates and improve the stability and reliability of template casting;

[0018] (7) Set up an operating platform to facilitate the erection of the support platform and the template. I-beams are inserted into the reserved hole 2 and locked. The platform is easy and quick to build and has low cost.

[0019] (8) The forces on the diagonal braces and the support platform are clear. The stress nodes can be clearly identified and strengthened through software calculation. Most of the node processes are pre-embedded and welded, which are simple, easy to inspect and manage, and safe and reliable.

[0020] (9) The pre-reserved holes in the wall and the embedded steel plates serve as the load-bearing support system for the support platform. The longitudinal support beams of the I-beams are easy to install. Angle steel is used as the figure-eight braces, which are easy and quick to weld. The upper support system (formwork support frame) is effectively transferred to the main structure of the wall. The support steel platform is a ground-based high formwork, which is a common formwork. It avoids the large investment in steel pipe scaffolding, reduces labor intensity, occupies little space, and facilitates three-dimensional cross-operations. Attached Figure Description

[0028] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0029] Example 1: As Figure 1-6As shown, the formwork support frame for high-altitude connecting beams includes multiple uprights 301, multiple horizontal trusses 302, and a support platform 303. The support platform 303 is detachably fixed to the two side walls 4. The lower ends of the multiple uprights 301 are fixedly connected to the support platform 303. The multiple horizontal trusses 302 are vertically and spaced apart and fixedly connected to the multiple uprights 301. Compared with traditional full-span scaffolding, the typical support for high-altitude connecting beams is a suspended high-formwork system, which can make full use of the building structure's own bearing capacity, save on foundation reinforcement materials and scaffolding usage, and has a high steel recycling rate for the support and I-beam platform, making it economical and reasonable. The bottom and top horizontal trusses 302 are equipped with first scissor bracing 309, and the two sides and the middle surface of the uprights 301 between the two walls 4 are equipped with second scissor bracing 310. The use of scissor bracing can further strengthen the support stability and reliability of the formwork support frame.

[0030] Specifically, the support platform 303 includes multiple longitudinal support beams 304 arranged laterally at intervals. The two ends of each longitudinal support beam 304 are fixedly connected to two end transverse support beams 305. The two end transverse support beams 305 are fixedly connected to two longitudinal double-end cantilever beams 306. The two longitudinal double-end cantilever beams 306 move longitudinally through longitudinal pre-drilled holes 401 in the side walls 4 and are locked in place by longitudinal wedges 402. The bottom surface of the longitudinal pre-drilled holes 401 is flush with the top surface of the first floor slab under the connecting beam. The support platform also includes multiple intermediate transverse support beams 308, with the two ends of each intermediate transverse support beam 308... The transverse support beam passes through the transverse pre-drilled holes 407 on both sides of the wall 4 and is locked with transverse wedges 408. The upper sides of multiple intermediate transverse support beams 308 are fixedly connected to multiple longitudinal support beams 304. The longitudinal double-end cantilever beams and intermediate transverse support beams are installed using the longitudinal pre-drilled holes 1 and the transverse pre-drilled holes 1 respectively. The installation and removal are convenient and quick, and the support is stable and reliable. The support platform skeleton, composed of longitudinal double-end cantilever beams, intermediate transverse support beams, longitudinal support beams and end transverse support beams, has good support strength and rigidity, and high support stability. It can ensure the stable pouring of the connecting beam and avoid sinking that would reduce the reliability of the connection with the walls on both sides.

[0031] To further improve the reliability of the support platform, each intermediate transverse support beam 308 is equipped with a figure-eight-shaped diagonal brace 307 at its bottom. The upper end of the diagonal brace 307 is fixedly connected to the intermediate transverse support beam 308, and the lower end is fixedly connected to the pre-embedded steel plate 403 set on the surface of the wall 4. The figure-eight-shaped angle steel diagonal brace can reinforce the longitudinal support beam. By setting the pre-embedded steel plate on the wall surface and welding it to the diagonal brace, the support point on the wall surface is more stable and the connection is more reliable, avoiding damage to the wall surface that could lead to detachment.

[0032] To further improve the reliability of the diagonal bracing, the embedded steel plate 403 is equipped with anchoring steel bars that are fixedly connected to it. The anchoring steel bars are fixedly connected to the wall steel bars in the wall 4. The embedded steel plate is equipped with anchoring steel bars to improve the stability and reliability of the connection between the embedded steel plate and the wall surface, avoid slippage due to excessive force, and improve the support reliability of the diagonal bracing.

[0033] To further improve the reliability of the diagonal brace, the diagonal brace 307 is welded and fixed to the embedded steel plate 403. The embedded steel plate 403 is fixedly connected to a limit strip 404. The limit strip 404 is located at the bottom of the welding point between the diagonal brace 307 and the embedded steel plate 403 and abuts against the diagonal brace 305. The limit strip can prevent the diagonal brace from slipping down after the welding is loose, thus improving the reliability of the connection.

[0034] To facilitate the construction of the formwork support system, the formwork support frame for the high-altitude connecting beam also includes an operating platform 6 installed two floors below the connecting beam. The operating platform 6 includes multiple H-beams 601, steel plates 602, and end transverse H-beams 603. The steel plates 602 are fixedly connected to the top surfaces of the multiple longitudinal H-beams 601. The two ends of the multiple longitudinal H-beams 601 overlap with two end transverse H-beams 603. The two end transverse H-beams 603 overlap with two longitudinal double-headed cantilever H-beams 604. The two longitudinal double-headed cantilever H-beams 604 respectively move through the longitudinal reserved holes 405 in the two side walls 4 and are locked with longitudinal wedges 406. The operating platform also includes multiple intermediate transverse H-beams 605. Both ends of each intermediate transverse H-beam 605 pass through the transverse pre-drilled holes 409 in the two side walls 4 and are locked in place with wedges 410. The upper sides of the multiple intermediate transverse H-beams 605 are fixedly connected to multiple longitudinal H-beams 601. The operating platform facilitates the erection and dismantling of the support platform and templates. The H-beams are inserted into the longitudinal and transverse pre-drilled holes and locked in place with wedges. Steel plates are welded to the longitudinal H-beams, making platform construction convenient, quick, and cost-effective. The pre-drilled holes ensure easy and quick assembly and disassembly, and the platform support is stable and reliable.

[0035] Example 2: As Figure 1-6As shown, a high-altitude connecting beam formwork structure is used for the construction of connecting beams in high-rise buildings. The specific structure includes side formwork 1, bottom formwork 2, and formwork support frame 3. The side formwork 1 is fixedly connected to the formwork support frame 3 and arranged at intervals. Both ends of the side formwork 1 abut against the side walls 4. The bottom formwork 2 abuts against and is enclosed at the bottom of the side formwork 1, with both ends abutting against the side walls 4. The formwork support frame 3 includes multiple uprights 301, multiple horizontal trusses 302, and a support platform 303. The support platform 303 is detachably fixedly connected to the side walls 4. The lower ends of the multiple uprights 301 are fixedly connected to the support platform 303. The horizontal truss 302 is vertically fixedly connected to multiple uprights 301 at intervals. Compared with traditional full-span scaffolding, the typical support for high-altitude beams is a suspended high-formwork system, which can make full use of the building structure's own bearing capacity, save on foundation reinforcement materials and scaffolding usage, and has a high steel recycling rate for the support and I-beam platform. It is economical and reasonable. The bottom and top horizontal trusses 302 are equipped with first scissor bracing 309, and the two sides and the middle of the uprights 301 between the two walls 4 are equipped with second scissor bracing 310. The use of scissor bracing can further strengthen the support stability and reliability of the formwork support frame.

[0036] Specifically, the support platform 303 includes multiple longitudinal support beams 304 arranged laterally at intervals. The two ends of each longitudinal support beam 304 are fixedly connected to two end transverse support beams 305. The two end transverse support beams 305 are fixedly connected to two longitudinal double-end cantilever beams 306. The two longitudinal double-end cantilever beams 306 move longitudinally through longitudinal pre-drilled holes 401 in the side walls 4 and are locked in place by longitudinal wedges 402. The bottom surface of the longitudinal pre-drilled holes 401 is flush with the top surface of the first floor slab under the connecting beam. The support platform also includes multiple intermediate transverse support beams 308, with the two ends of each intermediate transverse support beam 308... The transverse support beam passes through the transverse pre-drilled holes 407 on both sides of the wall 4 and is locked with transverse wedges 408. The upper sides of multiple intermediate transverse support beams 308 are fixedly connected to multiple longitudinal support beams 304. The longitudinal double-end cantilever beams and intermediate transverse support beams are installed using the longitudinal pre-drilled holes 1 and the transverse pre-drilled holes 1 respectively. The installation and removal are convenient and quick, and the support is stable and reliable. The support platform skeleton, composed of longitudinal double-end cantilever beams, intermediate transverse support beams, longitudinal support beams and end transverse support beams, has good support strength and rigidity, and high support stability. It can ensure the stable pouring of the connecting beam and avoid sinking that would reduce the reliability of the connection with the walls on both sides.

[0037] To further improve the reliability of the support platform, each intermediate transverse support beam 308 is equipped with a figure-eight-shaped diagonal brace 307 at its bottom. The upper end of the diagonal brace 307 is fixedly connected to the intermediate transverse support beam 308, and the lower end is fixedly connected to the pre-embedded steel plate 403 set on the surface of the wall 4. The figure-eight-shaped angle steel diagonal brace can reinforce the longitudinal support beam. By setting the pre-embedded steel plate on the wall surface and welding it to the diagonal brace, the support point on the wall surface is more stable and the connection is more reliable, avoiding damage to the wall surface that could lead to detachment.

[0038] To further improve the reliability of the diagonal bracing, the embedded steel plate 403 is equipped with anchoring steel bars that are fixedly connected to it. The anchoring steel bars are fixedly connected to the wall steel bars in the wall 4. The embedded steel plate is equipped with anchoring steel bars to improve the stability and reliability of the connection between the embedded steel plate and the wall surface, avoid slippage due to excessive force, and improve the support reliability of the diagonal bracing.

[0039] To further improve the reliability of the diagonal brace, the diagonal brace 307 is welded and fixed to the embedded steel plate 403. The embedded steel plate 403 is fixedly connected to a limit strip 404. The limit strip 404 is located at the bottom of the welding point between the diagonal brace 307 and the embedded steel plate 403 and abuts against the diagonal brace 305. The limit strip can prevent the diagonal brace from slipping down after the welding is loose, thus improving the reliability of the connection.

[0040] To improve the stability and reliability of the formwork casting, two formwork frames 7 are set on the outer side of the two side formworks. Multiple rows of tie rods 5 are arranged vertically between the two formwork frames 7. The formwork frames and tie rods can prevent the side formwork from bursting and improve the stability and reliability of the formwork casting.

[0041] To facilitate the construction of the formwork support system, the formwork support frame for the high-altitude connecting beam also includes an operating platform 6 installed two floors below the connecting beam. The operating platform 6 includes multiple H-beams 601, steel plates 602, and end transverse H-beams 603. The steel plates 602 are fixedly connected to the top surfaces of the multiple longitudinal H-beams 601. The two ends of the multiple longitudinal H-beams 601 overlap with two end transverse H-beams 603. The two end transverse H-beams 603 overlap with two longitudinal double-headed cantilever H-beams 604. The two longitudinal double-headed cantilever H-beams 604 respectively move through the longitudinal reserved holes 405 in the two side walls 4 and are locked with longitudinal wedges 406. The operating platform also includes multiple intermediate transverse H-beams 605. Both ends of each intermediate transverse H-beam 605 pass through the transverse pre-drilled holes 409 in the two side walls 4 and are locked in place with wedges 410. The upper sides of the multiple intermediate transverse H-beams 605 are fixedly connected to multiple longitudinal H-beams 601. The operating platform facilitates the erection and dismantling of the support platform and templates. The H-beams are inserted into the longitudinal and transverse pre-drilled holes and locked in place with wedges. Steel plates are welded to the longitudinal H-beams, making platform construction convenient, quick, and cost-effective. The pre-drilled holes ensure easy and quick assembly and disassembly, and the platform support is stable and reliable.

[0042] The operating principle is to use the existing wall structure to pre-reserved holes to cantilever I-beams and lay steel plates as an operating platform. Steel plates are pre-embedded in the walls on both sides as load-bearing supports for a typical figure-eight support system, supporting the main beam and connecting beams at the bottom of the entire load-bearing support, thus becoming the load-bearing foundation of the upper support system.

[0043] Example 3: As Figure 7 As shown, a construction method for a high-altitude connecting beam formwork structure includes the following steps:

[0044] 1) Structural verification and treatment

[0045] Calculate the load that the connecting beams and their own loads need to bear on the formwork support frame. These loads are transferred to the concrete structural beams and shear walls on both sides of the wall through longitudinal double-end cantilever beams, transverse support beams and V-shaped diagonal braces made of I-beams.

[0046] 2) Reserved openings and embedded side wall steel plates

[0047] When constructing to the second and first floors below the connecting beam, longitudinal reserved holes one, longitudinal reserved holes two, transverse reserved holes one and transverse reserved holes two are set in the walls on both sides. The longitudinal reserved holes one, longitudinal reserved holes two, transverse reserved holes one and transverse reserved holes two are larger than the dimensions of the longitudinal double-end cantilever beam, the intermediate transverse support beam, the longitudinal double-head cantilever I-beam and the intermediate transverse I-beam, respectively. Before the concrete is poured in the walls on both sides, embedded steel plates should be set on the outside of the walls. The embedded steel plates are installed at the same time as the wall reinforcement. The embedded steel plates should be connected to the wall reinforcement with anchor bars. The embedded position should correspond to the longitudinal support beam above and below.

[0048] 3) Erect the operating platform and install safety guardrails (railings) on the operating platform.

[0049] After the concrete strength of the two side walls meets the requirements, longitudinal reserved hole 2 and transverse reserved hole 2 are set in the second layer under the connecting beam. The longitudinal reserved hole 2 passes through the longitudinal double-headed cantilever I-beam and serves as the longitudinal support beam of the operating platform. The transverse reserved hole 2 passes through the middle transverse I-beam and is erected in conjunction with the end transverse I-beam and serves as the transverse support beam of the operating platform. After the longitudinal and transverse I-beams are erected, longitudinal wedge 2 (both wedge 1 and wedge 2 are wooden wedges) is used to fill and tighten the gap of the longitudinal reserved hole 2 and transverse wedge 2 is used to fill and tighten the gap of the transverse reserved hole 2. A steel plate is laid on the longitudinal I-beam and the steel plate is spot welded to the longitudinal I-beam to serve as the operating platform.

[0050] 4) Erect I-beam longitudinal support beams

[0051] Two longitudinal support beams are formed by passing through two I-beams through the longitudinal reserved holes on both sides of the first floor under the connecting beam. Two intermediate transverse support beams are formed by passing through multiple I-beams through the transverse reserved holes on both sides of the first floor under the connecting beam. Two end transverse support beams are fixedly welded to both ends of the two longitudinal support beams. Connecting plates are welded to the upper surfaces of the intermediate transverse support beams and the end transverse support beams to form a support platform. The gap between the longitudinal support beam and the first longitudinal reserved hole is secured with a longitudinal wedge, and the gap between the intermediate transverse support beam and the second transverse reserved hole is secured with a transverse wedge.

[0052] 5) Welding the figure-eight diagonal braces

[0053] Angle steel is used as the diagonal bracing. Based on the angle between the angle steel, the longitudinal support beam of the I-beam, and the wall, both ends of the angle steel are cut into horizontal and vertical surfaces. The vertical surface is welded to the embedded steel plates in the two side walls as a load-bearing fulcrum. A φ10 round steel bar is welded horizontally below the fulcrum as a limit strip to prevent the channel steel from being pulled downward and cracking the weld after being stressed. The horizontal surface is welded to the bottom of the longitudinal support beam of the I-beam. The welding quality should be guaranteed. After the welding is completed, the welding quality should be fully inspected. If it does not meet the requirements, it should be repaired.

[0054] 6) Scaffolding system erection

[0055] The uprights are installed on the longitudinal support beams of the I-beams. The feet of the uprights are fixed by spot welding or by welding vertical steel nails to the I-beams to anchor the uprights. The horizontal and longitudinal spacing of the uprights is determined according to the stress calculation. The uprights are fixed by a horizontal truss composed of multiple horizontal or longitudinal additional horizontal bars.

[0056] 5) Template Installation

[0057] The elevation of the connecting beam position is determined by measurement. The uprights are erected to the bottom of the connecting beam. The wooden formwork is assembled according to the design dimensions of the connecting beam. First, the bottom formwork is assembled, then the side formwork on one side is assembled. The steel reinforcement of the connecting beam is tied, and then the side formwork on the other side is assembled. The back ribs composed of tie rods and formwork skeleton are used for reinforcement. The tops of the two side formworks are also fixed with spaced reinforcing wooden boards. The dimensions of the formwork are checked.

[0058] 8) Construction of cast-in-place concrete components

[0059] After the reinforcement and formwork of the connecting beam have passed inspection, concrete is poured. The concrete is poured using a tower crane to lift the concrete hopper. The connecting beam is poured in two layers, with each pouring height not exceeding 50cm. The lower layer of concrete is poured before the initial setting of each layer. During the pouring process, the formwork and supports are inspected to ensure the stability of the supports.

[0060] 9) Scaffold dismantling

[0061] After the connecting beam construction is completed and the concrete strength meets the demolding strength requirements, the formwork support frame is dismantled. The principle for dismantling the formwork support frame is to dismantle the first erected parts and the last erected parts first. The connecting beam formwork is dismantled in the following order: first the side formwork, then the bottom formwork. After all the connecting beam formwork is dismantled, the steel pipe uprights are dismantled from top to bottom, followed by the angle steel diagonal braces, support plates, longitudinal support beams, end transverse support beams, middle transverse support beams, and longitudinal double-end cantilever beams. Finally, the operating platform is dismantled. The steel plate, longitudinal I-beams, and transverse I-beams of the operating platform are dismantled. The middle transverse I-beams are pulled out from the transverse pre-reserved hole two, and the longitudinal double-end cantilever I-beams are pulled out from the longitudinal pre-reserved hole two. After dismantling, the longitudinal pre-reserved hole one, longitudinal pre-reserved hole two, transverse pre-reserved hole one, and transverse pre-reserved hole two are sealed with micro-expansion concrete that is one grade higher than the original concrete of the wall. During the dismantling process, the dismantling materials are transported in a timely manner, and it is strictly forbidden to pile too much material on the scaffold.

[0062] This invention's construction method is applicable to high-altitude beam construction, offering convenient operation, rapid construction speed, reduced labor costs, and effective prevention of safety risks associated with working at heights, ensuring safety during such operations. In construction projects, it can be used in high-rise and super high-rise buildings by pre-reserving holes and embedding steel plates, without being limited by site conditions or the height-to-width ratio of the support frame. It allows for three-dimensional cross-operation, saving on the amount of reusable materials such as steel pipe frames, supports, and fasteners, and reducing their service life. Furthermore, it eliminates the need for a ground-based foundation, saving on hardened concrete.

[0063] After the construction is completed, the I-beams, angle steel, steel plates, etc. can be reused or disposed of as waste materials, which can generate 79,212 yuan.
