Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to an umbrella-shaped hanging hole device. Background Technology

[0002] During the construction process, various holes are pre-drilled in the floor slab, such as wiring holes and material transfer holes. In the later stages of construction, these holes need to be sealed to ensure the integrity and waterproofing of the floor slab.

[0003] For sealing pre-reserved holes in floor slabs, the following conventional methods are mainly used. These include: the formwork and wire method, which involves building wooden formwork to cover the hole and then securing the formwork with wire; the steel pipe top support method, which uses vertical steel pipes to support the lower formwork and requires the erection of scaffolding layer by layer; and the precast concrete block sealing method, which requires pre-making concrete blocks that match the size of the hole for sealing.

[0004] Regarding the aforementioned technologies, the precast concrete block method suffers from poor adhesion between the concrete blocks and the building floor slab, posing a safety hazard; in the formwork pouring method, the formwork is fixed with wire, which can easily shift and cause concrete leakage; and the scaffolding method requires on-site scaffolding erection, resulting in low construction efficiency. Utility Model Content

[0005] To improve the sealing effect and construction efficiency of reserved holes in floor slabs, this application provides an umbrella-shaped hanging hole device.

[0006] This application provides an umbrella-shaped hanging hole device, which adopts the following technical solution:

[0007] An umbrella-shaped hanging hole device includes a pre-embedded screw, an umbrella-shaped template, and a support device;

[0008] The umbrella-shaped template includes a central rod, umbrella ribs, control components, and umbrella fabric. The end of the central rod is detachably connected to the pre-embedded screw. The umbrella ribs are openable and closable on the central rod. The control components are used to control the opening or closing of the umbrella ribs. The umbrella fabric is disposed on the umbrella ribs and is located at the end of the umbrella ribs facing the pre-embedded screw. When the umbrella ribs are opened, the umbrella fabric is simultaneously expanded and can abut against the lower surface of the floor slab.

[0009] The support device includes a support rod and a limiting member. The end of the pre-embedded screw away from the central rod is detachably connected to the support rod. The limiting member is disposed on the support rod and can restrict the downward movement of the support rod.

[0010] By adopting the above technical solution, the pre-reserved holes in the floor slab are sealed by using umbrella-shaped templates and support devices, thus avoiding the problem of poor adhesion between precast concrete blocks and the floor slab. After the umbrella-shaped template is opened, the umbrella cloth abuts against the lower surface of the floor slab, preventing the concrete from leaking due to template displacement. There is no need to erect scaffolding on site, which improves construction efficiency.

[0011] Optionally, both the center rod and the support rod have threaded holes at one end facing the pre-embedded screw, and the two ends of the pre-embedded screw are threadedly connected to the center rod and the support rod, respectively.

[0012] By adopting the above technical solution, threaded connections are used to achieve detachable connections between the pre-embedded screw rod and the center rod and the support rod, which facilitates the assembly and disassembly of the hanging hole device and improves construction flexibility and efficiency.

[0013] Optionally, a water-stop ring is provided on the outer wall of the pre-embedded screw.

[0014] By adopting the above technical solution, the two ends of the pre-embedded screw are threaded to the center rod and the support rod respectively, and a water-stop ring is set on the outer wall of the pre-embedded screw, which can prevent water from seeping along the pre-embedded screw and ensure the waterproofness of the floor slab.

[0015] Optionally, the umbrella ribs include a first frame, a second frame, and a fixing ring. The control component includes a sliding ring and a positioning block. The fixing ring is located at the end of the central rod away from the pre-embedded screw. The positioning block is located at the end of the central rod close to the pre-embedded screw. The sliding ring is slidably sleeved on the central rod and located at the end of the positioning block close to the pre-embedded screw. One end of the first frame is rotatably mounted on the fixing ring, and one end of the second frame is rotatably mounted on the sliding ring, while the other end is rotatably connected to the first frame. Multiple sets of the first and second frames are arranged circumferentially along the central rod in a one-to-one correspondence. The umbrella fabric is mounted on the second frame, and the side of the umbrella fabric facing away from the pre-embedded screw is connected to all the second frames.

[0016] By adopting the above technical solution, the umbrella fabric is set on the second frame and connected to all the second frames, so that the umbrella fabric can be stably opened and abut against the lower surface of the floor slab when the umbrella ribs are opened, which makes it convenient to seal the reserved holes in the floor slab and avoids the problems of troublesome formwork construction and low construction efficiency in traditional sealing methods.

[0017] Optionally, the outer edge of the umbrella fabric facing the pre-embedded screw is provided with a double-sided adhesive strip.

[0018] By adopting the above technical solution, the umbrella-shaped hanging hole device can better adhere to the lower surface of the floor slab, preventing concrete leakage and improving the quality and stability of sealing the reserved holes in the floor slab.

[0019] Optionally, an elastic sealing strip is provided circumferentially on the outer edge of the umbrella fabric facing the pre-embedded screw.

[0020] By adopting the above technical solution, an elastic sealing strip is set around the outer edge of one side of the umbrella fabric, which improves the sealing performance between the umbrella fabric and the lower surface of the floor slab, avoids concrete leakage, and enhances the waterproofing effect when sealing the reserved holes in the floor slab.

[0021] Optionally, the umbrella fabric is PVC coated fabric.

[0022] By adopting the above technical solutions, the PVC coated fabric has good strength, flexibility, wear resistance, corrosion resistance and water resistance, which improves the durability and practicality of the umbrella-shaped hanging hole device.

[0023] Optionally, the outer wall of the support rod is provided with threads, and the limiting member includes a first sleeve threadedly connected to the support rod, a second sleeve threadedly connected to the support rod, a third sleeve rotatably disposed outside the second sleeve, a first rod rotatably disposed on the first sleeve, a second rod disposed outside the third sleeve, and a connecting sleeve slidably disposed on the first rod. The second sleeve is located at one end close to the pre-embedded screw, and the end of the second rod away from the third sleeve is rotatably connected to the connecting sleeve. Multiple sets of the first rod, the second rod, and the connecting sleeve are arranged along the circumference of the support rod.

[0024] By adopting the above technical solution, the threaded engagement of the support rod with the first and second sleeves, combined with a multi-group circumferential structure consisting of the third sleeve, the first rod, the second rod, and the connecting sleeve, can effectively restrict the downward movement of the support rod, improve the stability of the hanging hole device, and prevent the umbrella-shaped template from shifting or loosening due to the downward movement of the support rod, thereby ensuring the smooth progress of the floor slab hole sealing construction.

[0025] Optionally, a positioning ring is provided circumferentially on the inner sidewall of the third sleeve, and a positioning groove is provided on the outer sidewall of the second sleeve for the positioning ring to rotate.

[0026] By adopting the above technical solution, the third sleeve can rotate flexibly relative to the second sleeve.

[0027] Optionally, both the center rod and the support rod are provided with a suspension rope at the end away from the pre-embedded screw.

[0028] By adopting the above technical solution, when using the umbrella-shaped hanging hole device to seal the reserved holes in the floor slab, the hanging ropes set on the central rod and support rod make it easy for operators to move and install the device, thus improving the convenience of construction.

[0029] In summary, this application includes at least one of the following beneficial effects:

[0030] 1. The modular installation method using umbrella-shaped templates, pre-embedded screws, and support devices can improve template installation efficiency and allow for multiple uses, thus reducing costs;

[0031] 2. The opening and closing control method of the umbrella-shaped formwork allows for easy and quick installation simply by placing the umbrella-shaped formwork on the floor slab. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0038] This application discloses an umbrella-shaped hanging hole device. (Refer to...) Figure 1 The umbrella-shaped hanging hole device includes a pre-embedded screw rod 1, an umbrella-shaped template 2, and a support device 3. The pre-embedded screw rod 1 is detachably connected to the umbrella-shaped template 2 and the support device 3, respectively, so that the three can be flexibly assembled and disassembled, which facilitates construction operations and can be reused, thereby improving construction efficiency.

[0039] Reference Figure 1 and Figure 2In this embodiment, the umbrella-shaped template 2 includes a central rod 21, umbrella ribs 22, a control component 23, and an umbrella fabric 24. The central rod 21 is detachably connected to the pre-embedded screw 1. The umbrella ribs 22 are disposed on the central rod 21, and the umbrella fabric 24 is disposed on the umbrella ribs 22 and located at one end near the pre-embedded screw 1. The control component 23 is used to control the opening or closing of the umbrella ribs 22. When the umbrella ribs 22 are opened, the umbrella fabric 24 is spread out and pressed against the lower surface of the floor slab, which can seal the holes in the floor slab, thus forming the function of a template.

[0040] Reference Figure 1 and Figure 3 Specifically, the center rod 21 is preferably made of metal, and a threaded hole is opened at the end facing the pre-embedded screw 1. The end of the pre-embedded screw 1 and the center rod 21 are detachably connected by a threaded connection, which makes installation and disassembly convenient and quick. The umbrella rib 22 includes a first frame 221, a second frame 222 and a fixing ring 223, and the control component 23 includes a sliding ring 231 and a positioning block 232. The fixing ring 223 is a circular ring structure, which is coaxially fixed to the end of the central rod 21 away from the pre-embedded screw 1 by welding or other means; the positioning block 232 is set at the end of the central rod 21 near the pre-embedded screw 1, and it can be a circular ring structure or other shapes such as rectangle; the positioning block 232 can also be fixed by welding or other means; the sliding ring 231 is slidably sleeved on the central rod 21 and is located at the end of the positioning block 232 near the pre-embedded screw 1. The cooperation between the sliding ring 231 and the central rod 21 should ensure smooth sliding, and the inner side wall of the sliding ring 231 should smoothly abut against the outer side wall of the central rod 21.

[0041] Both the first frame 221 and the second frame 222 are slender metal rods. One end of the first frame 221 is rotatably mounted on the side wall of the fixing ring 223, and can be connected by a pin or other means to allow it to rotate up and down around the fixing ring 223. One end of the second frame 222 is rotatably mounted on the sliding ring 231, and the other end is rotatably connected to the first frame 221. Multiple sets of the first frame 221 and the second frame 222 are arranged in a one-to-one correspondence along the circumference of the central rod 21. The umbrella fabric 24 is mounted on the second frame 222, and the side of the umbrella fabric 24 facing away from the pre-embedded screw 1 is connected to all the second frames 222, for example, by sewing. At the same time, the center of the umbrella fabric 24 has a clearance hole for the sliding ring 231 to pass through. The central part of the umbrella fabric 24 is fixed to the side wall of the sliding ring 231, and the fixing method can be adhesive fixing, sewing fixing, mechanical pressing fixing, etc. Taking mechanical pressing as an example, the side wall of the sliding ring 231 can be designed as a double-layer clamping plate structure. For example, a metal pressure ring can be added to the outside of the sliding ring 231, and the central part of the umbrella fabric 24 can be pressed and fixed in the metal pressure ring by bolts or rivets.

[0042] During construction, the sliding ring 231 can be controlled to slide away from the positioning block 232, causing the umbrella ribs 22 to retract. Note that at this time, the sliding ring 231 should move upward onto the pre-embedded screw 1. At this time, the construction personnel can stand on the upper surface of the floor slab and then extend the retracted umbrella-shaped template 2 downward and through the floor slab hole. Next, slide the sliding ring 231 downward toward the positioning block 232, so that the sliding ring 231 abuts against the positioning block 232. At this time, the sliding ring 231 drives the umbrella ribs 22 to open, and the second frame 222 drives the umbrella cloth 24 to unfold to a near-horizontal state. Move the pre-embedded screw 1 upward so that the upper surface of the umbrella cloth 24 abuts against the lower surface of the floor slab, thus completing the sealing of the lower surface of the floor slab hole and completing the positioning of the umbrella-shaped template 2. Then, with the support device 3 supporting the umbrella-shaped template 2, concrete can be poured into the hole.

[0043] Furthermore, the umbrella fabric 24 needs to be made of a soft, waterproof material; preferably, it can be PVC coated fabric, which has good flexibility, waterproofness and abrasion resistance.

[0044] Alternatively, to improve the sealing effect between the umbrella fabric 24 and the lower surface of the floor slab, a double-sided adhesive strip or an elastic sealing strip can be circumferentially fixed to the side of the umbrella fabric 24 facing the pre-embedded screw 1, i.e., the outer edge of the upper surface of the umbrella fabric 24. Using a double-sided adhesive strip can enhance the adhesion between the umbrella fabric 24 and the lower surface of the floor slab and prevent concrete leakage; while using an elastic sealing strip, which can be a rubber strip, can play a dual role of buffering and sealing, further improving the sealing effect; at the same time, the elastic sealing strip can be used multiple times.

[0045] Reference Figure 1 and Figure 4 The support device 3 includes a support rod 31 and a limiting member 32. The support rod 31 can also be a metal rod, with a threaded hole on its lower end near the pre-embedded screw 1, and is threadedly connected to the pre-embedded screw 1 through the threaded hole. The outer wall of the support rod 31 is threaded. The limiting member 32 consists of a first sleeve 321, a second sleeve 322, a third sleeve 323, a first rod 324, a second rod 325, and a connecting sleeve 326. Among them, the second sleeve 322 is located at the end near the pre-embedded screw 1 relative to the first sleeve 321. Both the first sleeve 321 and the second sleeve 322 are threadedly connected to the sleeve 326 on the support rod 31. The third sleeve 323 is rotatably sleeved on the outside of the second sleeve 322. The upper end of the first rod 324 is hinged to the side wall of the first sleeve 321, and the lower end can rotatably abut against the surface of the floor slab. The connecting sleeve 326 is slidably sleeved on the first rod 324. The inner side of the second rod 325 is fixed to the third sleeve 323 by welding or other means, and the outer side is hinged to the connecting sleeve 326. Multiple sets of the first rod 324, the second rod 325 and the connecting sleeve 326 are arranged along the circumference of the support rod 31.

[0046] Furthermore, a positioning ring 327 is provided circumferentially on the inner wall of the third sleeve 323, and a positioning groove for the positioning ring 327 to rotate is provided on the outer wall of the second sleeve 322. This structure allows the third sleeve 323 to rotate relative to the second sleeve 322. At the same time, along the length direction of the support rod 31, the length of the second sleeve 322 is greater than that of the third sleeve 323.

[0047] In use, by rotating the first sleeve 321 and the second sleeve 322, the limiting member 32 is controlled to move closer to the floor slab. When the lower end of the first rod 324 abuts against the upper surface of the floor slab, support is formed, realizing the limiting function and restricting the downward movement of the support rod 31 and the umbrella-shaped template 2. By rotating the second sleeve 322 to move it closer to or further away from the first sleeve 321, the first rod 324 can be controlled to unfold or retract, thus adapting to holes of different sizes.

[0048] Reference Figure 1 In an optional embodiment, a water-stop ring 11 is provided on the outer wall of the pre-embedded screw 1. The water-stop ring 11 is preferably a metal ring, and its inner side is welded and fixed to the pre-embedded screw 1. The water-stop ring 11 can achieve the waterproof effect after the hole is sealed.

[0049] Reference Figure 1 In an optional embodiment, both the center rod 21 and the support rod 31 are equipped with lifting ropes 4 at their ends furthest from the pre-embedded screw 1. When installing the lifting ropes 4, mounting holes can be made radially on the center rod 21 and the support rod 31, and the lifting ropes 4 can be secured through these holes. The lifting ropes 4 facilitate the hoisting and transportation of the equipment after construction, improving the convenience of construction. It should be noted that after the center rod 21 and the support rod 31 are removed, the portions of the pre-embedded screw 1 inserted into the center rod 21 and the support rod 31 will be exposed on the upper and lower surfaces of the floor slab. In this case, they can simply be cut off according to conventional construction methods.

[0050] The implementation principle of this embodiment is as follows: During construction, the pre-embedded screw rod 1 and the umbrella-shaped template 2 are first connected, and the umbrella-shaped template 2 is passed through the reserved hole in the floor slab. Then, the sliding ring 231 is moved downward to open the umbrella rib 22, and the pre-embedded screw rod 1 is moved upward so that the umbrella cloth 24 abuts against the lower surface of the floor slab. Next, the support rod 31 is connected to the pre-embedded screw rod 1, and the first sleeve 321 and the second sleeve 322 are moved downward in sequence so that the second rod 325 abuts against the upper surface of the floor slab, restricting the downward movement of the support rod 31 and ensuring the stability of the device. After that, concrete is poured. After the concrete has solidified, the center rod 21 and the support rod 31 are rotated in the opposite direction to separate them from the pre-embedded screw rod 1, and the device is removed.

[0051] This device improves the efficiency of pouring holes in floor slabs through template-based construction; at the same time, the detachable connection method allows the umbrella-shaped template 2 and the support device 3 to be reused multiple times, reducing the cost of using the device.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
