Description

Suspension structure forming device

The present disclosure relates to a suspension point structure forming device, in particular to a suspension point forming device used to cooperate with a suspension support partially embedded in a concrete structure.

Precasting refers to a method of production in a factory, pouring concrete into reusable molds, solidifying and hardening in a controlled environment, and transporting it to the construction site for installation. The precasting method moves most of the work items that originally needed to be carried out on-site at the construction base to the factory, including beams, columns, floor slabs and other major components are all produced in the factory in a precast manner. Factory production has the advantages of a stable environment, no weather impact, low technical worker requirements, and standardized operations. On the construction site, mechanized equipment is used for assembly and hoisting work, and there is no need to build external scaffolding. The exterior wall and decoration are carried out simultaneously, effectively shortening the construction period. The only work left on the construction site is component assembly, steel bar connection, and very limited concrete pouring, which can greatly reduce the workload on the construction site. In addition, since traditional wooden formwork is not used on the construction site, it helps preserve forest resources and is environmentally friendly, and can keep the construction site neat and clean.

When the precast method is used, the beams, columns, floor slabs and other components produced in the factory need to be transported to the base site by means of transportation, such as trailers or trucks, and then transported to specific locations inside the building according to the different requirements of the building structure to facilitate construction. These units preferably have a hanging point structure for suspension, so that the relevant machinery can suspend these units through the hanging point structure when moving or adjusting the position of these components.

Therefore, the industry is in urgent need of a forming device that can be used during the concrete curing process to form a good hanging point structure when precasting the components.

The present disclosure provides a suspension point structure forming device for cooperating with a suspension pillar partially buried in a concrete structure, wherein the two ends of the suspension pillar respectively have an upper flange and a lower flange, and the lower flange is buried in the concrete structure. The suspension point structure forming device includes: a main body, which has a first cavity located therein and a first opening connected to the first cavity; and a connecting portion, which includes two symmetrical clamping structures, and the two symmetrical clamping structures are configured to clamp the upper flange of the suspension pillar together after being assembled; wherein the connecting portion is arranged in the first cavity of the main body, and a lower end of the connecting portion is arranged in the first opening of the main body.

The above has been a fairly broad overview of the technical features of the present disclosure so that the detailed description of the present disclosure below can be better understood. Other technical features that constitute the subject matter of the patent application scope of the present disclosure will be described below. Those with ordinary knowledge in the art to which the present disclosure belongs should understand that the concepts and specific embodiments disclosed below can be easily used as modifications or designs of other structures or methods to achieve the same purpose as the present disclosure.

The following disclosure provides many different embodiments or examples for implementing different features of the provided subject matter. Specific examples of components and configurations will be described below to simplify the disclosure. Of course, these are only examples and are not intended to be limiting. For example, in the following description, "forming a first component above or on a second component" may include embodiments in which the first component and the second component are formed in direct contact, and may also include embodiments in which additional components may be formed between the first component and the second component so that the first component and the second component may not be in direct contact. In addition, the disclosure may repeat component symbols and/or letters in various examples. This repetition is intended to simplify and clarify and does not itself indicate a relationship between the various embodiments and/or configurations discussed.

Additionally, for ease of description, spatially relative terminology (e.g., "below," "beneath," "below," "above," "upper," "above," and the like) may be used herein to describe the relationship of one element or component to another element or components as depicted in the figures. Spatially relative terminology is intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. The device may be otherwise oriented (rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein may be interpreted accordingly.

As used herein, terms such as "first", "second", and "third" describe various elements, components, regions, layers, and/or sections, which should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer, or section from another.

Unless otherwise specified, the horizontal or vertical mentioned in this article is usually relative to the ground of the building site. For example, the "horizontal direction" refers to the direction roughly parallel to the ground; the "vertical direction" refers to the direction roughly perpendicular to the ground; and the "horizontal height" generally refers to the distance from the ground.

FIG. 1 shows the preparation of a precast concrete structure 10, which may be a concrete wall. The outer contour of the concrete structure 10 may be defined by an outer mold 12 placed on the ground 20, and if necessary, a window hole of the concrete structure 10 may be prepared by an inner mold 14. After the mold is set, concrete 30 is poured into the space defined by the inner mold 14, the outer mold 12 and the ground 20 to prepare the concrete structure 10. In addition, before pouring the concrete 30, a steel reinforcement structure required for the concrete structure 10 may be pre-laid in the space defined by the inner mold 14, the outer mold 12 and the ground 20, such as the steel reinforcement 34 shown in FIG. 2.

After the concrete 30 is solidified, the concrete structure 10 can be moved away from the mold and the ground 20, and the concrete structure 10 can be placed at a suitable location in the required construction base through transportation and hoisting. According to an embodiment of the present disclosure, the operator can use one or more mobile tools (such as an overhead crane) and a hanging point structure 100 with a hook to facilitate the movement of the solidified concrete structure 10.

FIG2 shows a suspension point structure 100 according to the first embodiment of the present disclosure. The suspension point structure 100 includes a suspension column 110 partially embedded in a concrete 30, and the suspension column 110 has an upper flange 120 and a lower flange 140 at both ends thereof, and a long straight cylinder 130 located between the upper flange 120 and the lower flange 140, wherein the lower flange 140 is embedded in the concrete 30. At least a portion of the upper flange 120 and the cylinder 130 extend out of the concrete structure 10 from the recess 38 of the concrete structure 10, and do not extend beyond the main surface 32 of the concrete structure 10. It is advantageous that the suspension pillar 110 does not extend beyond the main surface 32 of the concrete structure 10. After the concrete structure 10 is set at a predetermined position on the construction site, the on-site construction personnel can pour concrete to fill the depression 38 so that the suspension pillar 110 is completely buried in the concrete structure 10, and the suspension point structure is smoothed so that the concrete structure 10 has a complete main surface 32. According to one embodiment of the present disclosure, the depression 38 has a bowl-shaped curved surface that bends toward the inside of the main surface 32 of the concrete structure 10.

The size and shape of the upper flange 120 and the lower flange 140 of the suspension support 110 may be the same or different. For example, as shown in FIG. 2 , the upper flange 120 is a cylinder with a diameter larger than the cylinder 130; and the lower flange 140 is a cone that is gradually pushed outward from the bottom end of the cylinder 130. As mentioned above, when pouring concrete 30, steel bars 34 may be pre-laid in the mold space. The suspension support 110 may be fixed to the steel bars 34 by means of a tie 36 (e.g., a steel wire or a tie band) to prevent the suspension support 110 from moving when pouring concrete 30.

3 and 4 show the hanging point structure forming device 200 of the first embodiment of the present disclosure, which can be used to form the aforementioned recess 38. Before pouring concrete 30, the hanging point structure forming device 200 is wrapped around the upper flange 120 of the suspension column 110; and after pouring concrete 30 and waiting for the concrete 30 to solidify, the hanging point structure forming device 200 can be removed to form the recess 38 around the upper flange 120 of the suspension column 110. Specifically, the hanging point structure forming device 200 has a chamber 210 and a first hole 220 connected to the chamber 210, the chamber 210 covers the upper flange 120 of the suspension pillar 110 and the first hole 220 covers at least a portion of the cylinder 130 of the suspension pillar 110, and the outer surface 240 of the hanging point structure forming device 200 contacts the concrete 30 before and after curing. After the concrete 30 is cured, the hanging point structure forming device 200 is removed to leave a hanging point structure 100 having a depression like the outer surface 240 of the hanging point structure forming device 200 on the surface of the concrete structure 10.

As shown in FIG. 4 , the hanging point structure forming device 200 is made of an elastic material (e.g., rubber), and has a cutout 250. The cutout 250 separates the first opening 220 of the hanging point structure forming device 200 and at least a portion of the chamber 210 into two equal parts, so that the hanging point structure forming device 200 can open the cutout 250 to be mounted on the suspension pillar 110 or removed from the suspension pillar 110.

3, the suspension point structure forming device 200 may further have a second opening 230, the second opening 230 is connected to the chamber 210 and is located on the opposite side of the first opening 220, wherein the suspension point structure forming device 200 further includes a screw 300, one end of the screw 300 has a flange 340, the flange 340 is disposed in the chamber 210 and the threaded body 310 of the screw 300 extends through the second opening 230. After passing through the second opening 230, the threaded body 310 of the screw 300 further extends through the gasket 330 and the bolt 320, and by tightening the bolt 320, the gasket 330 and the flange 340 are respectively on both sides of the second opening. Since the gasket 330 is against the opposite sides of the first opening 220 and the cutout 250 relative to the hanging point structure forming device 200, please refer to the opening state of the hanging point structure forming device 200 shown in FIG. 4. The gasket 330 against the hanging point structure forming device 200 can limit the opening of the hanging point structure forming device 200, so as to maintain the closure of the hanging point structure forming device 200 before and after the concrete 30 is solidified.

FIG5 shows a hanging point structure forming device 400 of the second embodiment of the present disclosure. The difference between the hanging point structure forming device 400 and the hanging point structure forming device 200 is that the hanging point structure forming device 400 has a separable two-piece design of a connecting portion 410 covering the upper flange 120 of the suspension support 110 and a body 420 contacting the concrete 30 to form the recess 38. Specifically, the body 420 has a first chamber 480 therein and a first opening 450 connected to the first chamber 480. Please refer to FIG. 5 and FIG. 6 , the connecting portion 410 includes two symmetrical clamping structures 410 ′ (see FIG. 6 ), and the two symmetrical clamping structures 410 ′ are configured to clamp the upper flange 120 of the suspension support 110 together after being assembled (see FIG. 5 ). The connecting portion 410 is disposed in the first chamber 480 of the body 420, and a lower end of the connecting portion 410 is disposed in the first opening 450 of the body 420; the outer surface 430 of the body 420 is a bowl-shaped curved surface, and the lowermost edge of the outer surface 430 of the body 420 is flush with the lowermost edge of the connecting portion 410, so that the connecting portion 410 produces a seal with the first opening 450, thereby preventing the concrete 30 from penetrating into the first chamber 480 of the body 420 before and after the concrete 30 is cured.

FIG6 shows a clamping structure 410' of an embodiment of the present disclosure. The clamping structure 410' has an appearance of a hollow semi-cylinder cut in half, so that two symmetrical clamping structures 410' form a cylinder when combined. The outer surface 440' of the clamping structure 410' has a curvature radius that is approximately equal to the first opening 450 of the main body. The inner surface 460' of the clamping structure 410' is configured to cover the upper flange 120 of the suspension support 110 and at least a portion of the cylinder 130, and the inner surface 460' has a curvature radius that is approximately equal to the upper flange 120 of the suspension support 110. The bottom of the clamping structure 410' has a semicircular cutout 470', and the cutout 470' has a radius of curvature substantially the same as that of the cylinder 130 of the suspension support 110. When the two symmetrical clamping structures 410' are assembled, a second chamber 460 is formed therein, and a second opening 470 is formed at the bottom of the connecting portion 410 (see FIG. 5). The shape of the upper flange 120 of the suspension support 110 matches the shape of the second chamber 460 of the connecting portion 410, and a portion of the cylinder 130 of the suspension support 110 is located in the second chamber 460 of the connecting portion 410.

In the second embodiment, the materials of the main body 420 and the connecting part 410 of the hanging point structure forming device 400 can be the same or different. Preferably, the main body 420 and the connecting part 410 are made of different materials. For example, the main body is made of metal material to facilitate machining or welding, and can make the concrete present a smooth surface after being separated from the concrete; while the connecting part 410 is made of elastic material. When the connecting portion 410 is made of elastic material, the diameter of the outer surface 440 of the connecting portion 410 can be slightly larger than the diameter of the first opening 450 of the main body 420, and the diameter of the second opening 470 of the connecting portion 410 can be slightly smaller than the diameter of the cylinder 130 of the suspension support 110, so that after the connecting portion 410 is sleeved on the outside of the suspension support 110 and the main body 420 is sleeved on the outside of the connecting portion 410, a good sealing effect can be produced for the first opening 450 and the second opening 470 through the elastic deformation of the connecting portion 410.

As shown in FIG. 5 , the body 420 of the suspension point structure forming device 400 has a plate 500 disposed opposite to the first opening 450, wherein the plate 500 of the body 420 and the bowl-shaped curved surface (i.e., the outer surface 430) of the body 420 jointly define the first chamber 480, and the plate 500 can be fixed to the body 420 by welding. In addition, the suspension point structure forming device 400 further includes a fixing device, which is used to firmly set the suspension point structure forming device 400 in the concrete structure. The fixing device includes a screw 510 fixed to an outer surface of the plate 500 of the body 420, and a handle 540 having a threaded inner hole 550, the threaded inner hole 550 matches the outer thread 530 of the screw 510, so that the handle 540 can be adjusted by sleeved on the screw 510 through the threaded inner hole 550. One end of the screw rod 510 may have a flange 520 as needed, and the flange 520 is welded to the plate 500 to be connected to the plate 500. When the concrete 30 is solidified, the on-site construction personnel can directly pull the body 420 upwards to separate it from the connecting part 410 by the handle 540, and then peel the connecting part 410 in half to complete the hanging point structure 100.

In addition, the plate 500 of the body 420 can be spaced apart from the top edge 600 of the body 420 by a predetermined distance D. During operation, the plate 500 is substantially flush with the main surface 32 of the concrete structure 10, and the predetermined distance D is sufficient to avoid entering the body 420 and above the plate (500) during the concrete pouring process of the concrete structure 10.

FIG. 7A shows a real photo of the hanging point structure forming device of the first embodiment; FIG. 7B shows a real photo of the hanging point structure formed by the hanging point structure forming device of the first embodiment. Please refer to FIG. 3-4 and FIG. 7A-7B at the same time. The hanging point structure forming device 200 of the first embodiment is set on the suspension support 110 or separated from it by opening the cutout 250. After the concrete 30 is solidified, in order to open the cutout 250, the on-site construction personnel need to destroy the edge of the bowl-shaped depression (as shown in FIG. 7B) so as to effectively open the cutout 250 and separate the hanging point structure forming device 200 from the suspension support 110, which will cause the appearance of the hanging point structure 100 to be damaged.

FIG. 7C shows a real photo of the hanging point structure forming device of the second embodiment; FIG. 7D shows a real photo of the hanging point structure formed by the hanging point structure forming device of the second embodiment. Please refer to FIG. 5-6 and FIG. 7C-7D at the same time. The hanging point structure forming device 400 is connected to the suspension support 110 through the connecting portion 410. When the main body 420 is pulled straight up by the construction personnel, the bowl-shaped concave space left is enough for the construction personnel to split the connecting portion 410 in half. As shown in FIG. 7D, the bowl-shaped concave surface of the hanging point structure 100 formed by the hanging point structure forming device 400 of the second embodiment is smooth and complete.
