Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to an operating platform for chimneys in high-rise buildings. Background Technology

[0002] In the construction of chimneys in high-rise buildings, traditional methods often use wooden formwork systems. However, the confined space inside the chimney makes it difficult for workers to enter and disassemble the formwork, resulting in low construction efficiency, significant safety hazards from falls, and quality problems such as concrete leakage and misalignment. Existing operating platforms are mostly temporary structures with poor structural stability and low turnover, failing to meet the construction needs of the confined space of chimneys and hindering collaborative operation with aluminum formwork systems, thus restricting the improvement of chimney construction quality and efficiency. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this utility model proposes an easy-to-install, highly safe operating platform for chimneys in high-rise buildings.

[0004] The technical solution of this utility model is as follows: an operating platform for a chimney in a high-rise building, including a platform base plate, a protective flap is rotatably installed on each side of the platform base plate, adjacent protective flaps are connected by a zipper and a zipper ring, and U-shaped plates are provided at the four corners of the back of the platform base plate.

[0005] During construction, the operating platform is hoisted to the chimney location on the construction floor using a tower crane. The bottom U-shaped plate is then placed on the pre-embedded support beams and secured in place. The platform provides a working surface for operations such as aluminum formwork installation, rebar tying, and concrete pouring. Protective flaps ensure construction safety. After construction on this floor is completed, the support beams are removed, and the platform is lifted to the next floor using a tower crane, repeating the above steps for reuse.

[0006] In one embodiment, the protective flap is mounted to the platform base plate via a hinge.

[0007] In one embodiment, the protective flap has a first state and a second state.

[0008] In the first state, the protective flap is perpendicular to the platform base plate;

[0009] In the second state, the protective flap has an angle α with the platform base plate, where 90 < α ≤ 180°.

[0010] In one embodiment, the protective flap includes a first protective flap, a second protective flap, a third protective flap, and a fourth protective flap. The first and second protective flaps are arranged in parallel, and the third and fourth protective flaps are arranged in parallel. The first and second protective flaps are provided with zippers, and the third and fourth protective flaps are provided with zipper rings. The installation positions of the zippers and zipper rings correspond to each other.

[0011] In one embodiment, positioning steel bars and lifting rings are provided at the four corners of the front of the platform base plate.

[0012] In one embodiment, the positioning reinforcement bar protrudes from the platform base plate.

[0013] In one embodiment, the lifting ring has a semi-circular arc structure.

[0014] In one embodiment, the U-shaped plate includes a first plate and a second plate, which are arranged in parallel, forming an erection space between the first plate and the second plate.

[0015] In one embodiment, the platform base plate includes a main frame and an anti-slip steel plate. The main frame has a square structure, and the anti-slip steel plate is adapted to the main frame and welded into the main frame.

[0016] This utility model has the following beneficial effects:

[0017] Suitable for operation in confined spaces: The compact structure allows for direct use inside the chimney, solving the problem of limited space inside the chimney and the inability of workers to enter to assemble and disassemble the formwork.

[0018] Safe and reliable: The design of anti-slip panels, protective flaps, and U-shaped plates effectively reduces the risk of falls from heights and being struck by objects, and the load-bearing capacity of the operating platform meets the construction load requirements.

[0019] High efficiency turnover: It can be used for recycling by vertical lifting with tower crane, so as to realize the simultaneous construction of vertical and horizontal structures of the smoke well and shorten the construction cycle.

[0020] Improve construction quality: The aluminum formwork system provides a stable working surface, ensuring the accuracy of formwork installation, making the surface of the chimney smooth and the dimensions precise, achieving a plaster-free effect.

[0021] Good economic benefits: Standardized design allows for repeated use, reducing material waste and lowering construction costs. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Before the construction of the flue, a standardized internal mold operation platform, made of square steel and patterned steel plate, is designed according to the size of the flue and the construction requirements.

[0031] like Figures 1-2 As shown, the platform base plate 1 in this embodiment includes a main frame 101 formed by welding four high-strength Q345B square steels end to end, and an anti-slip steel plate 102 with surface embossing to enhance friction. The size of the operating platform is customized according to the size of the chimney and construction requirements before the construction of the chimney, and is adapted to a well channel of not less than 800mm×800mm.

[0032] In this embodiment, each side of the platform base plate 1 is rotatably equipped with a protective flap 2, including a first protective flap 201, a second protective flap 202, a third protective flap 203, and a fourth protective flap 204. The first protective flap 201 and the second protective flap 202 are arranged in parallel, and the third protective flap 203 and the fourth protective flap 204 are arranged in parallel. The first protective flap 201 and the second protective flap 202 are provided with a zipper 3, and the third protective flap 203 and the fourth protective flap 204 are provided with a zipper ring 4. The first protective flap 201 and the third protective flap 203 are connected by the zipper 3 and the zipper ring 4, and the second protective flap 202 and the fourth protective flap 204 are connected by the zipper 3 and the zipper ring 4.

[0033] In this embodiment, a semi-circular lifting ring 6 is welded to each of the four corners of the front of the platform base plate 1 for lifting and hoisting the platform.

[0034] In this embodiment, four positioning steel bars 5 protruding from the platform base plate 1 are welded to the four corners of the front of the platform base plate 1. The positioning steel bars 5 are welded together with the four uprights of the operating frame 12 to fix the operating frame 12 on the platform base plate 1.

[0035] PVC pipe sleeves (DN100) with through-steel pipes are pre-embedded in the shear wall 9 of each floor of the flue, serving as positioning holes for the support beam 10.

[0036] In this embodiment, the U-shaped plate 7 includes a first plate 701 and a second plate 702, which are arranged in parallel, forming a support space between them. The platform base plate 1 is supported on two steel pipe support beams 10 via the U-shaped plate 7 on its back. The two ends of the support beams 10 are fixedly inserted into the positioning holes reserved in the vertical shear wall 9 of the chimney. A φ20 anti-slip nail is welded to each of the positions where the support beams 10 intersect with the outer edge of the shear wall 9. When removing the support beams, they should be rotated 180° clockwise or counterclockwise so that the anti-slip nails face upwards before removal.

[0037] like Figures 3-5 As shown, during the construction of the first floor of the smoke well, this utility model should be hoisted into the smoke well and installed in place when there is an operating frame on the first floor. The operating platform is placed directly on the bottom scaffolding and positioned according to the predetermined position. The operating platform is adjusted to a horizontal state using the U-shaped plate 7 set on the back of the platform base plate 1 and reliably connected to the structural floor slab with pre-embedded bolts or expansion bolts to prevent displacement and shaking.

[0038] In this embodiment, the protective flap 2 is rotatably installed on the outside of the main frame of the platform base plate 1 using hinge 8. The protective flap 2 has a first state and a second state.

[0039] In the first state, the protective flap 2 is perpendicular to the platform base plate 1;

[0040] In the second state, the included angle between the protective flap 2 and the platform base plate 1 is α, where 90 < α ≤ 180°.

[0041] When workers are working on the platform base plate 1, the protective flap 2 is rotated to tilt it relative to the platform base plate 1, which is used to cover the gap between the platform base plate 1 and the chimney wall to prevent objects from falling from height.

[0042] After the formwork on this floor is removed, the four protective flaps 2 are rotated to a vertical position (perpendicular to the platform base plate 1). Adjacent protective flaps 2 are secured using zippers 3 and zipper rings 4 to facilitate lifting and prevent collisions with the well wall. The operating frame and platform base plate 1 are lifted using a tower crane. The support beam 10 is rotated so that the anti-slip steel bar ends face upwards and removed. The support beam at this height is then removed and installed in the pre-drilled hole on the next floor. The above steps are repeated until all floors of the chimney construction are completed. Two workers cooperate during platform lifting: one worker hoists the operating platform to the upper level (below the aluminum formwork), while the other worker installs the support beam 10 on the lower level and lowers the platform after installation. This operating platform provides a reliable and safe working platform for the installation and removal of the inner formwork of the chimney, as well as concrete repairs, enabling simultaneous construction of the vertical shear wall structure and the horizontal floor slab structure of the chimney.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
