Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically an integrated shaft formwork system. Background Technology

[0002] In building construction, especially when pouring various concrete cylindrical structures such as elevator shafts and ventilation shafts, cylindrical formwork is required. Traditional cylindrical formwork is usually of fixed size, and once made, its dimensions are difficult to change. This means that when faced with cylindrical pouring tasks requiring different sizes, construction teams often need to prepare multiple sets of cylindrical formwork of different specifications, which not only increases construction costs but also occupies a large amount of storage space. Furthermore, during construction, the installation and dismantling of fixed-size cylindrical formwork is cumbersome due to the inability to flexibly adjust to the actual site conditions, consuming a significant amount of manpower and time, and seriously affecting construction efficiency. For example, in some renovation projects of old buildings, it is necessary to expand or modify the cylindrical structure of the original building; in this case, traditional fixed-size cylindrical formwork simply cannot meet the construction requirements. In summary, existing cylindrical formwork technologies suffer from problems such as non-adjustable dimensions, poor flexibility, high construction costs, and low construction efficiency, urgently requiring a new type of adjustable cylindrical formwork to solve these problems.

Detailed Implementation

[0025] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0027] It should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation in the specification, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0029] Please see Figures 1-12 In this embodiment of the utility model, the integrated vertical shaft template system includes a rectangular platform body 1. Template components 26 are slidably installed at the four edges of the top of the platform body 1. Angle molds 13 are fixedly connected to both ends of the template components 26. A corner mold 6 is provided between every two adjacent angle molds 13. The angle molds 13 and the corresponding corner molds 6 are slidably connected. A connecting shaft 19 is rotatably installed on the corner mold 6. Bidirectional screws 20 are fixedly installed at both ends of the connecting shaft 19. The bidirectional screws 20 are rotatably connected to the corner molds 6. Two nuts 21 are fitted onto the outer wall of each bidirectional screw 20. Two inclined rods 22 are hinged to the outer wall of each nut 21. Two connecting rods 23 are fixedly connected to the outer wall of each angle mold 13. The end of the inclined rod 22 away from the nut 21 is rotatably connected to the corresponding connecting rod 23.

[0030] By adopting the above-mentioned solution, after the concrete component 31 (vertical shaft) is poured and cured, this utility model only requires rotating each connecting shaft 19 to rotate each bidirectional screw 20. The bidirectional screw 20 and the nut 21 can then be used to drive each corner mold 13 to slide on the corresponding corner mold 6. This allows the template assembly 26 to move away from the four inner walls of the concrete component 31, while simultaneously moving the four corner molds 6 away from the four internal corners of the concrete component 31, thereby achieving demolding of the concrete component 31. The operation is simple and convenient, and for vertical shafts of different sizes, only template assemblies 26 of appropriate size need to be used.

[0031] Specific combination Figure 4 In one embodiment of this utility model, a geared motor 25 is fixedly mounted on the outer wall of the corner mold 6. The output shaft of the geared motor 25 is connected to the connecting shaft 19. By using the geared motor 25 to drive the connecting shaft 19, the automatic opening and closing of the corner mold 6, the corner mold 13 and the template assembly 26 can be realized in conjunction with the motor control system, thereby effectively reducing the labor intensity of workers.

[0032] Specific combination Figure 2 and Figure 3 In one embodiment of this utility model, the bottom of the platform body 1 is fixedly connected to a plurality of uprights 2 by upright connecting rods, a plurality of crossbars 3 are fixedly connected between the plurality of uprights 2, a plurality of scaffold boards 4 are fixedly connected to the bottom ends of the plurality of uprights 2, and a plurality of support rods 5 are fixedly installed at the bottom of the platform body 1, and a guide wheel 32 is installed at the end of each support rod 5 away from the platform body 1.

[0033] Further, the platform main body 1 is welded by square tubes or section steels, with diamond pattern steel plates laid on the top. The vertical rod connecting rod is used to connect with the vertical rod 2. The support rod 5 is welded by square tubes or section steels, and a guide wheel 32 and a backing plate are arranged at the front end of the support rod 5. The guide wheel 32 can reduce the friction between the support rod 5 and the concrete member 31 when the platform main body 1 is lifted.

[0034] Furthermore, the vertical rod 2 and the vertical rod connecting rod are connected by bolts, and the cross bar 3 is connected to the vertical rod 3 by bolts, which can not only stabilize the structure but also function as a guardrail. The脚手板4 is connected to the lowest cross bar 3 through a脚手板 connecting piece.

[0035] Specifically combined with Figure 1 , in an embodiment of the present invention, guardrails 30 are fixedly connected to the tops of the template assemblies 26. The guardrails 30 are mainly welded by square tubes or round tubes, with the upper part designed as a large "return" shape and the lower part designed as a small "rectangle" shape. The main purpose is the universality of the guardrails 30. When the size of the shaft changes, the guardrails 30 can also meet the construction requirements to the greatest extent.

[0036] Specifically combined with Figure 12 , in an embodiment of the present invention, the template assembly 26 includes multiple templates 27, backing ribs 28 and flat bolts 29. The templates 27 can be composed of aluminum alloy templates, high-strength steel templates and other material templates. The backing ribs 28 can be welded by square tubes and section steels or extruded from aluminum alloy profiles. The flat bolts 29 connect the backing ribs 28 and the templates together through bolts.

[0037] In addition, please combine Figure 6 and Figure 7 In an embodiment of the present invention, the corner mold 6 includes two first side plates 8 fixedly connected perpendicular to each other. Both ends of the two first side plates 8 are commonly fixedly connected with first end plates 7. A plurality of first connection seats 9 and second connection seats 11 are fixedly connected between the two first side plates 8. The bidirectional screw rod 20 is rotatably connected to the corresponding first connection seats 9 and second connection seats 11 through bearing seats 24. A motor mounting seat 12 is commonly fixedly connected to the two first side plates ৮. The reduction motor 25 is fixedly installed on the motor mounting seat 12. Chutes 10 are opened on the first connection seats 9. The corner mold 13 includes two second side plates 15 fixedly connected to each other. Both ends of the two second side plates 15 are commonly fixedly connected with second end plates 14. A plurality of reinforcing ribs 18 are commonly fixedly connected between the two second side plates 15. Sliders 16 are fixedly installed on the second side plates 15. The sliders 16 are slidably installed in the corresponding chutes 10. Connection seats 17 are fixedly installed on the outer walls of the second side plates 15. The connecting rod 23 is fixedly connected to the corresponding connection seats 17 through bolts.
