Description

Technical Field

[0001] This utility model mainly relates to the field of elevator shaft construction technology, specifically an aluminum formwork structure for elevator shafts in high-rise residential buildings. Background Technology

[0002] In modern high-rise buildings, elevators, as a means of transportation, provide great convenience to people. However, the installation of existing high-rise elevators first requires the construction of elevator shafts. In the traditional way, the construction of elevator shafts involves erecting steel pipe scaffolding from bottom to top as a construction platform for workers, then fixing inner and outer aluminum formwork to form an aluminum formwork structure, and pouring materials into the aluminum formwork from the construction platform, thus constructing the elevator shaft layer by layer from bottom to top.

[0003] In the aforementioned existing technology, the construction platform and aluminum formwork structure are independent of each other. Workers directly erect the aluminum formwork structure to match the building height before pouring concrete. When constructing high-rise residential buildings, the required aluminum formwork structure is large and difficult to recycle, easily leading to waste. Furthermore, the construction platform erected using steel pipe scaffolding has poor stability, posing a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum formwork structure for elevator shafts in high-rise residential buildings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum formwork structure for an elevator shaft in a high-rise residential building, comprising an outer aluminum formwork and an inner aluminum formwork located inside the outer aluminum formwork. Both the outer and inner aluminum formworks are C-shaped structures, and a fixing plate is detachably provided between their ends. A construction platform is detachably provided on the top of the inner aluminum formwork, and a suspended ceiling is provided on the top of the construction platform. An adjustable support leg is hinged to the bottom of the construction platform, and the adjustable support leg rotates from the vertical position toward the C-shaped opening to enter the outer residential floor.

[0006] The inner aluminum mold includes two side templates, two corner templates and a central template. One side of the side template is connected to one side of the outer aluminum mold through a fixing plate, and the other side of the side template is connected to the central template through a corner template.

[0007] Preferably, the side template has an L-shaped cross-section, with the horizontal axis of the L-shape of both side templates facing inward and located near the C-shaped opening of the outer aluminum mold. The distance between the horizontal axis of the L-shape of the two side templates is the same as the distance between the C-shaped opening of the outer aluminum mold, thereby forming a rectangular opening between the two fixed plates to accommodate the external elevator door.

[0008] Preferably, multiple crossbeams are equidistantly arranged vertically on the side template and the center template. The two ends of the corner template extend inward in the vertical direction to form an extension end. A drive motor is fixedly installed at the bottom of the extension end located at the top. The corner template also extends inward to form a reinforcement end. The bottom of the drive motor is connected and fixed to the reinforcement end. The output end of the drive motor penetrates the reinforcement end and is connected to a drive rod. The other end of the drive rod is rotatably connected to the extension end at the bottom. A threaded segment is formed on the drive rod at a position corresponding to any crossbeam. Any threaded segment forms threads of the same length but opposite directions from the center to both ends. Movable blocks are threaded to both ends of the threaded segment. Pull rods are hinged between the movable blocks and the crossbeams on both sides.

[0009] Preferably, the tops of the side template, corner template, and center template are equidistantly formed with multiple first connecting holes, and bolts are threaded along the first connecting holes from the top of the construction platform to connect and fix the side template, corner template, center template, and construction platform.

[0010] Preferably, the fixing plate has two rows of screw holes arranged in an array, the screw holes corresponding to the side wall positions of the side template and the outer aluminum mold, and bolts are installed along the screw holes to connect and fix the side template, the outer aluminum mold and the fixing plate.

[0011] Preferably, there are two adjustable support feet. Two connecting columns are provided at the bottom of the construction platform near the opening of the outer aluminum formwork. A horizontal reinforcing strip is fixed on the connecting column. Multiple first adjustment holes are formed at equal intervals on the horizontal reinforcing strip. A connecting screw hole is formed through the adjustable support foot in the horizontal direction, and multiple equal-distance second adjustment holes are formed symmetrically on both sides of its bottom end. Multiple third adjustment holes are formed at equal intervals in the vertical direction at the bottom end of the connecting column. When the adjustable support foot is rotated to the point where any second adjustment hole coincides with a third adjustment hole, the connecting screw hole coincides with one of the first adjustment holes, thereby forming a triangular support between the adjustable support foot, the connecting column, and the horizontal reinforcing strip with the external bolt. The part of the adjustable support foot that enters the outer residential floor also forms a triangular support with the residential floor floor and the connecting column.

[0012] Furthermore, a fixing frame is provided between the two connecting columns. The fixing frame includes two horizontal shafts and two vertical shafts. The two horizontal shafts are threadedly connected to a first adjusting hole, and the outer sides of the two vertical shafts are threadedly connected to a second adjusting hole located in the inward position.

[0013] Preferably, the bottom of the adjustable support foot is circular, and its circular surface is formed with anti-slip texture.

[0014] Preferably, the adjustable support foot is provided with diagonal bars on both sides of its bottom end, and a foot support is provided at the other end of the diagonal bar. The foot support is pressed against the ground of the external residential floor, and multiple second connection holes are formed in an array on the foot support.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model provides an aluminum formwork structure for elevator shafts in high-rise residential buildings. Two rows of screw holes on a fixing plate connect a C-shaped inner aluminum formwork and an outer aluminum formwork to form an aluminum formwork that fits the elevator shaft. A first connecting hole connects the inner aluminum formwork to a construction platform, making the aluminum formwork and construction platform an integrated unit. A fixed ceiling on the top of the construction platform, in conjunction with an external crane, lifts the formwork as a whole. Adjustable support legs allow it to be positioned close to the ground at the outer residential floor level for secure clamping of the overall structure. The height of the aluminum formwork only needs to match the floor height for layer-by-layer lifting and pouring, avoiding waste of aluminum formwork material.

[0017] This utility model provides an aluminum formwork structure for elevator shafts in high-rise residential buildings. The connecting columns and horizontal reinforcing strips at the bottom of the construction platform cooperate with adjustable support feet to form a triangular support. During the rotation and adjustment of the adjustable support feet, the positions of the second and third adjustment holes are selected according to the floor height, ensuring that the bottom of the adjustable support feet is firmly against the external residential floor floor. This, in conjunction with the residential floor floor and the connecting columns, forms a triangular support. The bottom of the adjustable support feet is circular with anti-slip textured surfaces. The bottom of the adjustable support feet is also connected to outward-facing foot supports. The second connecting holes formed on the foot supports are further connected and reinforced with pre-drilled holes on the residential floor floor, resulting in a relatively stable overall structure.

Detailed Implementation

[0028] The embodiments of this utility model 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 this utility model, and should not be construed as limiting this utility model.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 5 As shown, an aluminum formwork structure for an elevator shaft in a high-rise residential building includes an outer aluminum formwork 2 and an inner aluminum formwork located inside the outer aluminum formwork 2. Both the outer aluminum formwork 2 and the inner aluminum formwork are C-shaped structures. A fixing plate 4 is detachably installed between the ends of the two. A construction platform 5 is detachably installed on the top of the inner aluminum formwork. A suspended ceiling 6 is installed on the top of the construction platform 5. An adjustable support leg 9 is hinged to the bottom of the construction platform 5. The adjustable support leg 9 rotates from the vertical position toward the C-shaped opening to enter the outer residential floor.

[0031] The inner aluminum mold includes two side templates 1, two corner templates 8 and a center template 3. One side of the side template 1 is connected to one side of the outer aluminum mold 2 through a fixing plate 4, and the other side of the side template 1 is connected to the center template 3 through the corner template 8.

[0032] The side template 1 has an L-shaped cross-section. The horizontal axis of the L-shape of the two side templates 1 faces inward and is located near the C-shaped opening of the outer aluminum formwork 2. The distance between the horizontal axis of the L-shape of the two side templates 1 is the same as the distance between the C-shaped opening of the outer aluminum formwork 2, thereby forming a rectangular opening between the two fixed plates 4 to accommodate the external elevator door. Before building the aluminum formwork structure, different sizes of side templates 1 and outer aluminum formwork 2 are selected according to the floor height and door frame size of the residential building, so as to adapt to the floor conditions.

[0033] Multiple crossbeams 7 are equidistantly arranged vertically on the side template 1 and the center template 3. The two ends of the corner template 8 extend inward in the vertical direction to form an extension end. A drive motor 11 is fixedly installed at the bottom of the extension end located at the top. The corner template 8 also extends inward to form a reinforcing end 10. The bottom of the drive motor 11 is connected and fixed to the reinforcing end 10. The output end of the drive motor 11 penetrates the reinforcing end 10 and is connected to a drive rod 12. The other end of the drive rod 12 is rotatably connected to the extension end at the bottom. A threaded segment is formed on the drive rod 12 at a position corresponding to any crossbeam 7. Any threaded segment forms threads of the same length but opposite directions from the center to both ends. Movable blocks 13 are threadedly connected to both ends of the threaded segment. Pull rods 14 are hinged between the movable blocks 13 and the crossbeams 7 on both sides. The two movable blocks 13 of the same threaded segment are driven by the drive motor 11 to move in opposite directions, thereby pulling the side template 1 and the center template 3 inward to retract, which facilitates the demolding of the inner and outer aluminum molds.

[0034] The tops of the side template 1, corner template 8 and center template 3 are equidistantly formed with multiple first connecting holes 15. Bolts are threaded along the first connecting holes 15 from the top of the construction platform 5 to connect and fix the side template 1, corner template 8, center template 3 and construction platform 5.

[0035] The fixing plate 4 has two rows of screw holes arranged in an array. The screw holes correspond to the side wall positions of the side template 1 and the outer aluminum mold 2. Bolts are installed along the threads of the screw holes to connect and fix the side template 1, the outer aluminum mold 2 and the fixing plate 4, thereby realizing the integrated connection of the structure. During the layer replacement construction, the inner aluminum mold, the outer aluminum mold 2 and the construction platform do not need to be disassembled and separated.

[0036] The adjustable support feet 9 are of two types. Two connecting columns 16 are installed at the bottom of the construction platform 5 near the opening of the outer aluminum formwork 2. A horizontal reinforcing strip 18 is fixedly installed on each connecting column 16. Multiple first adjustment holes 20 are formed equidistantly on the horizontal reinforcing strip 18. The total length of the horizontal reinforcing strip 18 does not exceed sixty centimeters to ensure that workers can reach it from the external residential floor. A connecting screw hole is formed horizontally through each adjustable support foot 9, and multiple equidistant second adjustment holes 21 are symmetrically formed on both sides of its bottom end. Multiple... When the adjustable support leg 9 rotates to the point where any of the second adjustment holes 21 and the third adjustment hole 22 coincide, the connecting screw hole coincides with one of the first adjustment holes 20. This allows the external bolts to form a triangular support between the adjustable support leg 9, the connecting column 16, and the horizontal reinforcing strip 18. The portion of the adjustable support leg 9 that enters the external residential floor also forms a triangular support with the residential floor floor and the connecting column 16. Through the cooperation of the second adjustment hole 21 and the third adjustment hole 22, the position is selected for connection and fixation according to the floor height, so that the adjustable support leg 9 provides internal and external triangular support, resulting in relatively stable support.

[0037] A fixing frame 17 is also provided between the two connecting columns 16. The fixing frame 17 includes two horizontal shafts and two vertical shafts. The two horizontal shafts are respectively threaded to a first adjusting hole 20. The outer sides of the two vertical shafts are threaded to a second adjusting hole 21 located in the inward position. The fixing frame 17 further reinforces the adjustable support foot 9.

[0038] Multiple climbing poles 19 are also equidistantly arranged vertically between the two connecting columns 16, making it convenient for workers to directly enter the construction platform 5 from the external residential floor via the climbing poles 19.

[0039] The bottom of the adjustable support foot 9 is circular, and its circular surface is formed with anti-slip texture 23. The anti-slip texture 23 increases the friction at the bottom of the adjustable support foot 9, making it more stable in contact with the ground.

[0040] The adjustable support foot 9 has diagonal rods 24 on both sides of its bottom end, and foot support 25 on the other end of the diagonal rods 24. The foot support 25 is in close contact with the ground of the external residential floor. Multiple second connecting holes 26 are arranged in an array on the foot support 25. The foot support 25 is directly fixed to the external residential floor through the second connecting holes 26 and the reserved holes on the ground, thereby further improving the structural stability.

[0041] The implementation principle of this application embodiment is as follows: When using this product, it is necessary to customize and assemble the outer aluminum mold 2 and inner aluminum mold of corresponding sizes according to the floor height and elevator door spacing. The outer aluminum mold 2 and inner aluminum mold are fixed by the fixing plate 4, and the construction platform 5 is fixed on the top of the inner aluminum mold to realize the integration of the aluminum mold structure. Then, an external crane is used to lift the entire aluminum mold structure to the corresponding floor. The workers on the ground of that floor hook out two adjustable support feet 9 to their bottom ends and enter the floor. According to the floor conditions, the second adjustment hole 21 and the third adjustment hole 22 are selected at different positions to fix the adjustable support feet 9, and the fixing frame 17 is further installed. The foot support 25 is aligned with the reserved hole on the ground for connection and fixation. Then, the workers reach over... The horizontal reinforcing strip 18 is connected and fixed to the adjustable support leg 9 via the climbing pole 19, achieving a triangular support in two positions. During the fixing of the horizontal reinforcing strip 18, the body will be blocked by the climbing pole 19 and cannot enter the elevator shaft, thus reducing the risk of accidents due to mistakes. After fixing, the workers climb up the climbing pole 19 to the construction platform 5 and pour materials between the inner aluminum formwork and the outer aluminum formwork 2. After the construction of this floor is completed, it is only necessary to remove the fixing frame 17, the horizontal reinforcing strip 18 and the leg support 25, and the entire structure can be lifted to the next floor by an external crane. During the lifting process, the drive motor 11 drives the side formwork 1 and the center formwork 3 to pull inward and retract for easy demolding. The adjustable support leg 9 naturally returns to a position perpendicular to the construction platform 5 without obstructing the lifting. Repeating the above process can complete the pouring of the high-rise elevator shaft without the need for a large-volume aluminum formwork structure.

[0042] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from its essential characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
