Description

Technical Field

[0001] This utility model relates to the field of sealing technology, specifically a waffle hole sealing device. Background Technology

[0002] Waffle tubes, also known as waffle slabs or honeycomb panels, are the core components of reinforced concrete hollow floor slabs or roof slabs. Essentially, they are precast or cast-in-place concrete slabs with regular conical or cylindrical holes, named for their waffle-like arrangement of holes. Their core function is to achieve a balance between strong load-bearing capacity, light weight, and functional adaptability in large-span buildings. They are widely used in semiconductor factories, data centers, cleanrooms, large-span exhibition halls, and other scenarios with extremely high requirements for floor slab performance.

[0003] Traditional waffle hole sealing uses an iron cover plate to form line contact rather than surface contact, which is easy to move and leads to poor sealing. In addition, using iron sheet to seal the hole requires drilling holes in the ground and damaging the ground.

[0004] In view of this, the present invention solves the above-mentioned technical problems by proposing a waffle hole sealing device. Utility Model Content

[0005] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for a waffle hole sealing device, which solves the problems mentioned in the background technology.

[0006] This utility model provides the following technical solution: a waffle hole sealing device, including a cylindrical body, with sealing caps provided at both the upper and lower ends of the cylindrical body. The sealing caps have an internal notch design that allows them to fit tightly against the upper and lower ends of the cylindrical body. Four sliding grooves are provided on the outer walls of the upper and lower ends of the cylindrical body. The inner walls of the sealing caps are fixed with a number of sliders equal to the number of sliding grooves, and the sliders are distributed correspondingly to the sliding grooves. The sealing cap is tightly fitted to the upper and lower ends of the cylinder through a sliding connection between the slider and the groove. The inner walls of both sealing caps are fixed with limit rods. The end of the limit rod located on the inner wall of the lower sealing cap is a tubular structure, and the end of the limit rod located on the inner wall of the upper sealing cap can be inserted into the lower limit rod.

[0007] As a preferred technical solution of this utility model, the inner wall of the limiting rod of the tubular structure is fixed with a retaining ring, and the end of the limiting rod corresponding to the tubular structure is provided with multiple retaining blocks and distributed circumferentially on the outer wall. The position of one side of the retaining block opposite to the retaining ring is a sloping structure.

[0008] As a preferred technical solution of this utility model, the limiting rod is rotatably connected to a rotating rod inside, and the end of the rotating rod is fixed to a rotating ring by a connecting rod I at the position inside the limiting rod. The outer wall of the rotating ring rotates in close contact with the inner wall of the limiting rod, and the inner wall of the rotating ring is provided with a protrusion.

[0009] As a preferred technical solution of this utility model, a connecting block is fixed to the inner wall of the end of the limiting rod near the inclined surface of the locking block by a connecting rod II, and a spring with the same number of locking blocks is fixed to the outer wall of the connecting block, and the locking block passes through the outside of the limiting rod.

[0010] As a preferred technical solution of this utility model, a fixing block is fixed on the top of the card block, and the protrusion on the inner wall of the rotating ring contacts the fixing block, which can push the card block to contract or expand inside the limiting rod.

[0011] As a preferred technical solution of this utility model, the locking block passes through the locking ring and is pushed outward by the deformation expansion generated by the spring, locking it at the bottom of the locking ring and fixing the sealing cover to the end of the cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The deformation and expansion generated by the spring pushes the locking block to unfold outward of the limiting rod and lock it at the bottom of the locking ring. This can strengthen the covering force of the sealing cover and improve the sealing performance. It can prevent the sealing effect from being affected by falling or shifting due to collision during concrete pouring. The end of the locking block is set with a bevel so that it can pass through perfectly without obstruction between it and the locking ring when it enters the limiting rod.

[0013] 2. By having the protrusions on the inner wall contact the fixing block, the locking block is pushed to retract into the limit rod so that the contact length between the two locking blocks is less than the diameter of the retaining ring. The locking block then exits the limit rod, and the sealing cap on the top of the cylinder is removed. The hole can be reused, which can be flexibly applied according to the construction scenario to avoid inconvenience. At the same time, it is convenient to disassemble the sealing cap when the pipeline fails and needs to be repaired. After the repair is completed, it can be quickly resealed to ensure the sealing effect. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1-8 As shown, a waffle hole sealing device includes a cylinder 1. Both the upper and lower ends of the cylinder 1 are provided with sealing caps 2. The interior of the sealing caps 2 is designed with a notch so that it can fit tightly with the upper and lower ends of the cylinder 1 to avoid deformation of the cylinder 1 and affect the sealing effect. Four sliding grooves 101 are opened on the outer walls of the upper and lower ends of the cylinder 1. The inner wall of the sealing caps 2 is fixed with a number of sliders 201 equal to the number of sliding grooves 101, and the sliders 201 are distributed correspondingly to the sliding grooves 101. The sealing cover 2 is tightly fitted to the upper and lower ends of the cylinder 1 through the sliding connection between the slider 201 and the slide groove 101. The inner walls of both sealing covers 2 are fixed with limit rods 3. The end of the limit rod 3 located on the inner wall of the lower sealing cover 2 is a tubular structure, and the end of the limit rod 3 located on the inner wall of the upper sealing cover 2 can be inserted into the lower limit rod 3.

[0018] As a specific embodiment of this utility model, the inner wall of the limiting rod 3 of the tubular structure is fixed with a retaining ring 302. The end of the limiting rod 3 corresponding to the tubular structure is provided with multiple retaining blocks 3011 and distributed circumferentially on the outer wall. The position of the retaining block 3011 opposite to the retaining ring 302 is a sloping structure.

[0019] In one specific embodiment of this utility model, a rotating rod 301 is rotatably connected inside the limiting rod 3. A rotating ring 3013 is fixed to the end of the rotating rod 301 inside the limiting rod 3 via a connecting rod I 3012. The outer wall of the rotating ring 3013 rotates tightly against the inner wall of the limiting rod 3, and the inner wall of the rotating ring 3013 is provided with a protrusion.

[0020] In one specific embodiment of this utility model, a connecting block 3015 is fixed to the inner wall of the end of the limiting rod 3 near the inclined surface of the locking block 3011 via a connecting rod II 3017. The outer wall of the connecting block 3015 is fixed with the same number of springs 3016 as the locking blocks 3011. The locking blocks 3011 pass through the outside of the limiting rod 3.

[0021] As a specific embodiment of this utility model, the top of the locking block 3011 is fixed with a fixing block 3014. The protrusion on the inner wall of the rotating ring 3013 contacts the fixing block 3014, which can push the locking block 3011 to retract or expand inside the limiting rod 3, making it convenient to quickly disassemble and install the sealing cover 2.

[0022] In one specific embodiment of this utility model, the locking block 3011 passes through the locking ring 302 and is pushed outward by the deformation expansion generated by the spring 3016 to lock the bottom of the locking ring 302, thereby fixing the sealing cover 2 to the end of the cylinder 1.

[0023] When sealing the opening of the cylinder 1, the sealing cap 2 is first slidably fitted onto the openings at both ends of the cylinder 1 via the slider 201 and the groove 101 to seal both ends of the cylinder 1. Then, another sealing cap 2 is fitted and inserted to cover the top of the cylinder 1, so that the end of the rotating rod 301 is inserted into the limiting rod 3 on the surface of the lower sealing cap 2. When the rotating rod 301 enters the limiting rod 3, the locking block 3011 and the retaining ring 302 both contract inwards, allowing it to pass through the retaining ring 302. Then, the deformation expansion generated by the spring 3016 pushes the locking block 3011 outwards to the limit rod 3 and locks it at the bottom of the retaining ring 302. This can strengthen the covering force of the sealing cap 2 and improve the sealing performance, and prevent it from falling or shifting due to collision during concrete pouring, which would affect the sealing effect. The end of the locking block 3011 is set with a slope, so that when it enters the limiting rod 3, there is no obstruction between it and the retaining ring 302, allowing it to pass through perfectly. During construction, the temporary seal is used to prevent construction waste and moisture from entering the hole. When the main structure is completed and the hole needs to be disassembled for use, the rotating rod 301 can be rotated inside the limiting rod 3, and at the same time, the rotating ring 3013 can be rotated through the connecting rod I 3012. The rotating ring 3013 rotates and contacts the protrusion on the inner wall with the fixing block 3014, pushing the locking block 3011 to retract into the limiting rod 3, so that the contact length of the two locking blocks 3011 is less than the diameter of the locking ring 302, and it exits the interior of the limiting rod 3. The sealing cover 2 on the top of the cylinder 1 can be removed and the hole can be reused. It can be flexibly used according to the construction scenario to avoid inconvenience. At the same time, it is convenient to disassemble the sealing cover 2 when the pipeline fails and needs to be repaired. After the repair is completed, it can be quickly resealed to ensure the sealing effect.
