Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, specifically to a ribbed formwork hoisting structure. 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 installs the formwork piece by piece, which is inefficient and not safe. This utility model provides a more efficient and safer prefabricated ribbed formwork installation method and ribbed formwork hoisting structure.

[0005] This utility model is achieved through the following technical solution: a prefabricated ribbed formwork installation construction method, comprising the following steps:

[0006] Step 1: Construct the required formwork support structure;

[0007] Step 2: Pre-assemble the required formwork on the ground or floor to form multiple sets of formwork components. Each set of formwork components includes one or more rows of formwork connected as a whole.

[0008] Step 3: Using hoisting equipment and tools, hoist multiple sets of formwork components from the ground or floor to the required installation location, and connect adjacent sets of formwork components into a whole.

[0009] Furthermore, the mold shell includes a top surface, and a ring of downwardly extending side surfaces are connected around the top surface. 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 shell, and the connecting hole is horizontally arranged to extend from the cavity to the mating surface.

[0010] Furthermore, in step two, during pre-assembly, the mating surfaces of two adjacent mold shells are sequentially mated together and fastened together through the through-holes of fasteners.

[0011] Furthermore, in step three, two adjacent mold shell components are fitted together and fastened together by fasteners through the connecting holes.

[0012] Furthermore, the lifting tool includes a lifting frame and flexible ropes. The lifting frame is provided with a first lifting position for connecting to the lifting equipment. The lifting frame is provided with a plurality of second lifting positions, and the second lifting positions are connected to flexible ropes. The flexible ropes are connected to the mold shell, and the multiple flexible ropes form a multi-point lifting of the mold shell assembly.

[0013] Furthermore, the flexible rope includes one of the following: wire rope, suspension rope, and sling.

[0014] Furthermore, the flexible rope is a steel wire rope, which is hoisted by passing through the connection holes of the mold shell once or multiple times.

[0015] Furthermore, the ends of the wire rope are connected via an adjustable locking device.

[0016] Another aspect of this utility model provides a ribbed mold shell hoisting structure, including a mold shell assembly, a hoisting frame, and flexible ropes.

[0017] The mold shell assembly consists 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 flange's outer edge forms a mating surface for the mold shells to abut against each other. A connecting hole is provided on the mating surface of the mold shells. The connecting hole is horizontally positioned and extends from the cavity to the mating surface. The mold shell assembly is formed by the mating surfaces of multiple mold shells abutting against each other and being fastened together by fasteners passing through the connecting holes, arranged in one or more rows.

[0018] The length of the lifting frame is at least close to the length of the membrane shell assembly. The lifting frame is provided with a first lifting position for connecting to the lifting equipment. The lifting frame is provided with several second lifting positions, and the second lifting positions are connected to flexible ropes. The flexible ropes are lifted by passing through the connecting holes of the membrane shell once or multiple times. Multiple flexible ropes form a multi-point lifting of the membrane shell assembly.

[0019] Furthermore, the flexible rope is a steel wire rope, and the ends of the steel wire rope are connected by an adjustable locking device.

[0020] The beneficial effects of this utility model are:

[0021] 1. 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.

[0022] 2. This utility model improves construction efficiency.

[0047] 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.

[0048] Example 1

[0049] like Figure 1-11 As shown, a prefabricated ribbed formwork installation method includes the following steps:

[0050] Step 1: Erect the required support structure 20 for the formwork 10. The support structure 20 is not limited to a specific structure; it can be full-span scaffolding, or a column-and-steel truss beam configuration, or other structural forms that can effectively support the formwork 10, such as... Figure 9 As shown, this scheme uses full-span scaffolding, with a top support at the top of the scaffolding, and multiple steel pipes placed inside the top support. The span of the scaffolding is consistent with the span of the formwork.

[0051] Step 2: Pre-assemble the required formwork 10 on the ground or floor to form multiple sets of formwork components. Each set of formwork components includes one or more rows of formwork 10 connected as a whole. The formwork 10 used needs to have a structure that can rigidly connect with each other to ensure that the formwork components are connected to form a stable whole. The formwork 10 used in this solution is as follows: Figure 1-2 As shown, the mold includes a top surface 11, with downwardly extending side surfaces 12 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 extends horizontally outward to form a flange 14. The outer contour of the flange 14 is rectangular, and the vertical end face of the outer edge of the flange 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, horizontally extending from the cavity 13 to the mating surface 15. During pre-assembly, the mating surfaces 15 of adjacent mold shells 10 are sequentially mated together and fastened using fasteners passing through the connecting holes 16. This bolt tightening ensures that the mold shell assembly forms a stable whole. Prior to this, as... Figure 3 As shown, a convenient pre-assembly workbench can be set up on the ground. A structure similar to gymnastic parallel bars can be erected using scaffolding steel pipes, 0.9 meters wide, 7.5 meters long, and 1 meter high. Workers on the ground or floor place the formwork 10 on the steel pipes, with six formwork 10s per row. Figure 4 As shown, the mold shell 10 is suspended in the air, which allows workers to quickly tighten the bolts and nuts under the mold shell 10 using an electric wrench, and then wait for hoisting.

[0052] Step 3: Using the hoisting equipment 30 and hoisting tools 40, multiple sets of formwork components are sequentially hoisted from the ground or floor to the required installation location, and adjacent sets of formwork components are connected as a whole. The hoisting equipment 30 can be a tower crane or crane on the construction site. The hoisting tools 40 include a lifting frame 41 and flexible ropes 42. The lifting frame 41 is provided with a first lifting position 411, which is used to connect to the hoisting equipment 30. The lifting frame 41 is provided with several first lifting positions 411. The second lifting positions 412 are connected to the flexible ropes 42. The flexible ropes 42 are connected to the formwork 10, and multiple flexible ropes 42 form multiple hoisting points for the formwork components.

[0053] The purpose of the lifting tool 40 is to achieve multi-point lifting of the mold shell assembly, avoiding deformation of the mold shell assembly under stress. In this solution, the structural form of the lifting frame 41 is not limited; it can be rigid as a whole, with at least two first lifting positions 411 and several second lifting positions 412. The first lifting positions 411 and the second lifting positions 412 are not limited to specific structures, as long as they can allow the flexible rope 42 to be hung and have a limiting function. The limiting function refers to preventing the flexible rope 42 from moving along the length of the lifting frame 41. Generally, the interval of the second lifting positions 412 is consistent with the width of the mold shell 10 being lifted, so that each mold shell 10 has at least one lifting point. The mold shell assembly can be connected to the lifting frame 41 on both sides to keep it horizontal during lifting, or it can be connected to the lifting frame 41 on one side and lifted vertically during lifting.

[0054] like Figure 5 As shown, in this scheme, the lifting frame 41 is constructed using steel pipes of scaffolding, which are most commonly used on construction sites. The steel pipes are connected by cross buckles to form a rectangular frame. The connection node between the horizontal and vertical steel pipes can serve as a lifting point, and only the flexible rope 42 needs to be wrapped around the connection node.

[0055] like Figure 5 As shown, in this scheme, the flexible rope is a steel wire rope, and the upper end of the steel wire rope is wound around the connection node of the steel pipe, as shown. Figure 6 As shown, the lower end passes through the two connecting holes 16 of the mold shell 10 and then out again. Finally, the two ends of the wire rope are connected by an adjustable locking device 43. The adjustable locking device 43 is a standard purchased component. The connection structure between the wire rope and the adjustable locking device 43 is as follows: Figure 7-8 As shown, the wire rope inserted into the adjustable locking device 43 can only be tightened in one direction and cannot be pulled out directly. The wire rope can only be pulled out by pressing the spring of the adjustable locking device 43.

[0056] Therefore, after step two is completed, the lifting frame 41 is hung on the hook of the lifting equipment 30 by the slings. The lifting equipment 30 moves the lifting frame 41 to a position directly above the mold shell assembly and suspends it. The operator inserts and exits the wire rope through the two connection holes 16 of the mold shell 10. The upper end of the wire rope is wrapped around the connection node of the pipe, and both ends of the wire rope pass through the adjustable locking device 43 to form a self-locking mechanism. Then, as... Figure 10 As shown, the hoisting equipment 30 lifts the mold shell assembly to the required installation position of the mold shell 10 and lowers it onto the support structure 20. Once in a roughly suitable position, the worker presses the adjustable wire lock 43 to pull the wire rope out of the connection hole 16 of the mold shell 10. Workers at higher positions use a wooden hammer to tap the mold shell assembly, adjusting the position of the first set of mold shell assemblies to move it to the position specified in the drawing and fix it in place. The hoisting equipment 30 then proceeds to hoist the next mold shell assembly, as... Figure 11As shown, the second mold shell assembly is hoisted using the same method described above and placed on the support structure 20. After the wire rope is pulled out, a wooden hammer is used to tap it, causing the second mold shell assembly to fit snugly against the already positioned first mold shell assembly. Then, an electric wrench is used to quickly tighten the bolts and nuts until all mold shell assemblies are hoisted. Figure 12 As shown, they are connected as a whole.

[0057] In this scheme, the formwork 10 is pre-assembled, and multiple sets of formwork components are hoisted sequentially using hoisting equipment 30 and hoisting tools 40. This eliminates the need for workers to assemble the components one by one at a height. Workers at the height only need to press the adjustable wire locking device 43, pull out the wire rope, and fix the formwork components together. This reduces the amount of work at height, improves safety, and greatly increases efficiency, meeting the requirements of modern prefabricated construction.

[0058] Example 2

[0059] like Figure 13 As shown, the difference from Embodiment 1 is that the width of the lifting frame 41 can be set to be wider, so that a mold assembly with two or three rows of mold shells 10 can be lifted at once.

[0060] Example 3

[0061] The difference from Embodiment 1 is that the lifting frame 41 is made of steel truss or structural steel, as long as it has a certain rigidity and is equipped with a first lifting position 411 and several second lifting positions 412. Figure 14 As shown, this scheme uses an I-beam, with two lifting rings 44 on the top of the I-beam and six lifting rings 44 on the bottom, serving as the first lifting position 411 and several second lifting positions 412 respectively.

[0062] Example 4

[0063] like Figure 15 As shown, the difference from Embodiment 1 is that the wire rope can be inserted through the connection hole 16 on one side of the mold shell 10 and exit through the connection hole 16 on the other side of the mold shell 10. The upper end of the wire rope is wrapped around the second lifting position 412 and connected by the adjustable locking device 43, which can also meet the lifting of the mold shell assembly.

[0064] Example 5

[0065] like Figure 16 As shown, the difference from Embodiment 1 is that the flexible rope 42 can be a sling or a sling. The side of the mold shell 10 is provided with a threaded hole, and a lifting ring 44 is detachably installed at the threaded hole. After the sling or sling passes through the lifting ring 44, it is hung at the second lifting position 412, which can also achieve lifting. The sling and sling do not need to be disassembled. Each time, it is only necessary to tighten / unscrew the lifting ring 44 on the side of the mold shell 12.

[0066] In other embodiments, the mold shell 10 may employ other connection structures, as long as they ensure that the mold shell components are connected to form a stable whole.

[0067] Example 6

[0068] Another aspect of this utility model provides a ribbed mold shell hoisting structure, including a mold shell assembly, a hoisting frame 41, and a flexible rope 42. The structure of the mold shell assembly, hoisting frame 41, and flexible rope 42 is consistent with that of Embodiment 1.

[0069] like Figure 1-2 As shown, the mold shell assembly consists of multiple mold shells 10. Each 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 the mating surfaces 15 of multiple mold shells 10 abutting each other and being fastened together by fasteners passing through the connecting holes 16, arranged in one or more rows.

[0070] like Figure 5-8 As shown, the length of the lifting frame 41 is at least close to the length of the membrane shell assembly. The lifting frame 41 is provided with a first lifting position 411, which is used to connect with the lifting equipment 30. The lifting frame 41 is provided with a plurality of second lifting positions 412, and the second lifting positions 412 are connected to flexible ropes 42. The flexible ropes 42 are lifted by passing through the connecting holes 16 of the membrane shell 10 once or multiple times. The multiple flexible ropes 42 form multiple lifting points for the membrane shell assembly.

[0071] In practical applications, the flexible rope 42 is a steel wire rope, and the ends of the steel wire rope are connected by an adjustable locking device 43.

[0072] In summary, the prefabricated ribbed formwork installation method and ribbed formwork hoisting structure described in this utility model reduce the amount of high-altitude work, improve safety, and greatly increase efficiency, thus meeting the requirements of modern prefabricated construction.

[0073] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments are only for illustrating the technical concept and characteristics of this utility model, and are intended to enable those skilled in the art to understand and implement the content of this utility model.
