Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, specifically to a ribbed formwork hoisting structure that is easy to install. Background Technology

[0002] Miller floor slab formwork is a type of formwork used in construction engineering. It is mainly used for the construction of cast-in-place concrete two-way ribbed floor slabs (floor slabs) and is suitable for construction of large-span and high-load spaces, such as underground garages, large shopping malls, multi-story factories, school buildings, and civil defense projects.

[0003] In existing technologies, the supporting structure required for the formwork is usually erected first, and then the formwork is installed piece by piece manually at a height. This method of installation requires workers to spend a long time at height, poses significant safety hazards, and is inefficient, failing to meet the requirements of modern prefabricated construction. Utility Model Content

[0004] The problem solved by this utility model is that in the actual construction process, the existing technology requires the formwork to be installed piece by piece, which is inefficient and not safe. This utility model provides a ribbed formwork hoisting structure that is easy to install.

[0005] This utility model is achieved through the following technical solution: a convenient ribbed mold shell hoisting structure, including a mold shell assembly, a hoisting frame, a steel wire rope, and an adjustable locking device;

[0006] The mold shell assembly is composed of multiple mold shells. Each mold shell includes a top surface and a ring of downwardly extending side surfaces. The top surface and the surrounding side surfaces form a cavity. The lower edge of the side surfaces extends horizontally outward to form a flange. The outer contour of the flange is rectangular, and the vertical end face of the outer edge of the flange forms a mating surface between the mold shells. A connecting hole is provided on the mating surface of the mold shells. The connecting hole is horizontally arranged and extends from the cavity to the mating surface. The mold shell assembly is composed of multiple mold shells mating surfaces that abut against each other and are fastened together by fasteners passing through the connecting holes, arranged in one or more rows.

[0007] The lifting frame includes horizontal and vertical pipes, which are scaffolding steel pipes connected by cross-shaped couplings to form a rectangular whole.

[0008] Several sets of wire ropes and adjustable locking devices are provided. The wire ropes are wound around the cross buckle. The wire ropes pass through the connecting holes of the mold shell once or multiple times. The two ends of the wire ropes are connected by adjustable locking devices. Multiple sets of wire ropes and adjustable locking devices are used to hoist the mold shell assembly at multiple points.

[0009] Furthermore, the length of the horizontal tube is not less than the length of the mold assembly minus one mold.

[0010] Furthermore, the number of longitudinal tubes is not less than the number of mold shells in the length direction of the mold shell assembly.

[0011] Furthermore, the wire rope is inserted into and then exited through two adjacent connecting holes on the same side of the mold shell.

[0012] Furthermore, the wire rope enters from the connection hole on one side of the mold shell and exits from the connection hole on the other side of the mold shell. The upper end of the wire rope is wrapped with a cross buckle and connected by an adjustable locking device.

[0013] Furthermore, the wire rope (30) is inserted through the connection hole (16) on one side of a mold shell (10) and exits through the connection hole (16) of an adjacent mold shell (10). The upper end of the wire rope (30) is wrapped with a cross buckle (23) and connected by an adjustable locking device (40).

[0014] The beneficial effects of this utility model are:

[0015] 1. The lifting frame described in this utility model is assembled using scaffolding steel pipes and cross buckles. It is easy to obtain materials and install on the construction site. Each cross buckle can be used as a lifting position, allowing for flexible lifting.

[0016] 2. This utility model uses steel wire rope and adjustable locking device to hoist the mold shell assembly. The ends of the steel wire rope are connected through the adjustable locking device and locked in one direction. The operator can complete the installation by inserting the steel wire rope into the adjustable locking device. When disassembling, pressing the spring of the adjustable locking device can quickly remove it, making the operation very convenient.

[0017] 3. This utility model improves construction safety. The formwork is pre-assembled on the ground or floor, and then the formwork components are hoisted to the installation position as a whole using hoisting equipment and tools, which greatly reduces the amount of high-altitude work, lowers construction risks, and improves construction safety.

[0018] 4. This utility model improves construction efficiency. The pre-assembly of the formwork and the overall hoisting method make the construction process smoother, reduce the time for on-site assembly and adjustment, thereby improving construction efficiency, shortening the construction period, and meeting the requirements of modern prefabricated construction.

[0034] 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.

[0035] Example 1

[0036] like Figure 3 As shown, a convenient ribbed formwork hoisting structure includes a formwork assembly, a hoisting frame 20, a wire rope 30, and an adjustable wire lock 40.

[0037] The mold shell assembly consists of six mold shells 10, such as Figure 2As shown, the mold shell includes a top surface 11, and a ring of downwardly extending side surfaces 12 are connected around the top surface 11. The top surface 11 and the surrounding side surfaces 12 form a cavity 13. The lower edge of the side surfaces 12 continues to extend horizontally outward to form a flange edge 14. The outer contour of the flange edge 14 is rectangular, and the vertical end face of the outer edge of the flange edge 14 forms a mating surface 15 between the mold shells 10. A connecting hole 16 is provided on the mating surface 15 of the mold shell 10. The connecting hole 16 is horizontally arranged and extends from the cavity 13 to the mating surface 15. The mold shell assembly is formed by six mold shells 10 mating surfaces 15 abutting each other and being fastened together by fasteners passing through the connecting holes 16, arranged in a row of six pieces.

[0038] like Figure 3 As shown, the lifting frame 20 includes horizontal pipes 21 and vertical pipes 22. The horizontal pipes 21 and vertical pipes 22 are scaffolding steel pipes and are connected by cross buckles 23 to form a rectangular whole. The length of the horizontal pipe 21 is not less than the length of the formwork assembly minus the length of one formwork 10, ensuring that the outermost formwork 10 can be provided with a lifting point. The number of vertical pipes 22 is not less than the number of formwork 10 in the length direction of the formwork assembly. In this solution, there are three horizontal pipes 21 and six vertical pipes 22, which can ensure that each formwork 10 can be provided with a lifting point.

[0039] The steel wire rope 30 and the adjustable locking device 40 are provided in several sets. The steel wire rope 30 is wound around the cross buckle 23. The steel wire rope 30 passes through two adjacent connecting holes 16 on the same side of the mold shell 10 and then exits. Figure 4 As shown, the two ends of the wire rope 30 are connected by an adjustable locking device 40. Multiple sets of wire ropes 30 and adjustable locking devices 40 are used to hoist the mold shell assembly at multiple points. The adjustable locking device 40 is a standard purchased component. The connection structure between the wire rope 30 and the adjustable locking device 40 is as follows: Figure 5-6 As shown, the wire rope 30 can only be tightened in one direction when inserted into the adjustable locking device 40. It cannot be pulled out directly. The wire rope 30 can only be pulled out by pressing the spring of the adjustable locking device 40.

[0040] The lifting frame 20 of this solution is assembled using scaffolding steel pipes and cross-shaped buckles 23. On the construction site, the materials are readily available and the installation is convenient. Each cross-shaped buckle 23 can serve as a lifting position for winding the wire rope 30. The ends of the wire rope 30 are connected by an adjustable locking device 40, which is locked in one direction. The operator can simply insert the wire rope 30 into the adjustable locking device 40 to complete the installation. When disassembling, pressing the spring of the adjustable locking device 40 allows for quick disassembly, making the operation very convenient.

[0041] The main function of the hoisting structure in this scheme is to hoist the formwork components. In the existing technology, the support structure required for the formwork 10 is usually erected first, and then the formwork 10 is installed piece by piece by workers at a high altitude. This kind of installation requires workers to work at a high altitude for a long time, poses a greater safety hazard, and has low construction efficiency, which does not meet the requirements of modern prefabricated construction.

[0042] With the hoisting structure of this solution, the formwork 10 can be pre-assembled on the ground. Then, the lifting frame 20 and the formwork components are connected by multiple sets of wire ropes 30 and cross buckles 23 to achieve multi-point hoisting. The lifting frame 20 plays a connecting role between the hoisting equipment and the formwork components, and its rigidity and multi-point hoisting ensure that the formwork components will not deform during hoisting, thus improving the service life of the formwork 10. During installation, the hoisting equipment moves the formwork components from the ground to the required installation location. Workers at height only need to press the adjustable cable locking device 40, pull out the wire ropes 30, and fix the formwork components together. Workers do not need to assemble them one by one at height, reducing the amount of high-altitude work, improving safety, and greatly improving efficiency, meeting the requirements of modern prefabricated construction.

[0043] Example 2

[0044] like Figure 7 As shown, the difference from Embodiment 1 is that the wire rope 30 is inserted through the connecting hole 16 on one side of the mold shell 10 and exits through the connecting hole 16 on the other side of the mold shell 10. The upper end of the wire rope 30 is wrapped with a cross buckle 23 and connected by an adjustable locking device 40.

[0045] Example 3

[0046] like Figure 8 As shown, the difference from Embodiment 1 is that the wire rope 30 is inserted through a connection hole 16 of the mold shell 10, and comes out from the bottom surface of the flange edge 14 of the mold shell 10. The upper end of the wire rope 30 is wrapped with a cross buckle 23 and connected by an adjustable locking device 40.

[0047] Example 4

[0048] like Figure 9 As shown, the difference from Embodiment 1 is that the wire rope 30 is inserted into the connecting hole 16 on one side of a mold shell 10 and exits from the connecting hole 16 of an adjacent mold shell 10. The upper end of the wire rope 30 is wrapped with a cross buckle 23 and connected by an adjustable locking device 40.

[0049] Example 5

[0050] like Figure 10As shown, the difference from Embodiment 1 is that there are five horizontal pipes 21 and six vertical pipes 22, and both rows of mold shells 10 are hoisted simultaneously. This further improves installation efficiency.

[0051] In summary, the prefabricated ribbed formwork hoisting structure of this utility model is easy to source materials and install, reduces the amount of high-altitude work, improves safety, and greatly improves efficiency, thus meeting the requirements of modern prefabricated construction.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
