Description

Technical Field

[0001] The present application belongs to the technical field of post-cast strip sealing, and specifically relates to a post-cast strip sealing device. Background Art

[0002] In construction, a post-cast strip typically refers to the portion of concrete that cannot be poured simultaneously during the concrete pouring process due to structural design, construction procedures, or construction time. This post-cast strip must be properly sealed during subsequent construction to ensure the integrity and mechanical properties of the structure.

[0003] For example, the application with publication number CN207794147U discloses a post-cast strip closing device, comprising a cover plate, a triangular baffle, a first reinforcing rib, a second reinforcing rib and a third reinforcing rib; triangular baffles are provided at both ends of the cover plate, and a first reinforcing rib, a second reinforcing rib and a third reinforcing rib are provided at the bottom of the cover plate, the second reinforcing rib is T-shaped, and the first and third reinforcing ribs are L-shaped; the post-cast strip closing device of the utility model can prevent the cover plate from shifting through the triangular baffles, thereby improving the stability; and the strength of the device is improved through the first reinforcing rib, the second reinforcing rib and the third reinforcing rib; in the post-cast strip closing device of the utility model, the bottom of the cover plate is connected to the first reinforcing rib, the second reinforcing rib and the third reinforcing rib respectively through a card slot, which is convenient for disassembly and assembly, and convenient for transportation and turnover use; and an anti-slip layer is provided on the cover plate, and an anti-rust layer is provided on the anti-slip layer, which not only has an anti-slip effect but also extends the service life.

[0004] However, in this application, during construction, concrete is usually poured more to ensure construction quality, resulting in an increase in width. The sealing device cannot be adjusted in width, and the inability to fully cover the seal will affect the construction quality. Utility Model Content

[0005] The purpose of this application is to provide a post-casting strip sealing device in order to solve the above-mentioned problems.

[0006] The technical solution adopted in this application is as follows: a post-cast strip closing device, including a post-cast strip, the upper surface of the post-cast strip is fixedly connected to a main cover plate, the outer surfaces of both sides of the main cover plate are welded with bent cover plates, the lower surfaces of both sides of the main cover plate are welded with fixed seats, the inner surface of the fixed seat is movably connected to a movable rack, the outer surface of the movable rack is welded with a secondary cover plate, the lower surface of the main cover plate is welded with a fixed sleeve, and the inner surface of the fixed sleeve is movably sleeved with movable teeth.

[0007] By adopting the above technical solution, the equipment inserts and pulls the auxiliary cover plate into the main cover plate. Under the action of the fixed seat, the movable rack and the auxiliary guide plate move corresponding to the inner surface of the fixed seat, and the gear corresponding to the movable rack engages with the movable gear, so that the auxiliary cover plates on both sides are displaced inward or outward at the same time to adjust the width to be sealed. The inclined surface of the bent cover plate is squeezed against the auxiliary cover plate, and the interaction force of the fixed seat is cooperated to fix the auxiliary cover plate, thereby completing the seal above the post-casting strip.

[0008] In a preferred embodiment, a ventilation groove is provided on the outer surface of the bent cover plate away from the main cover plate, and a limit baffle is fixedly connected to the outer surface of the bent cover plate away from the main cover plate.

[0009] By adopting the above technical solution, the corresponding channel of the hole on the upper side of the ventilation slot is connected to the corresponding limit baffle on the side of the bent cover plate. After the adjustment is completed, glue is poured through the ventilation slot to complete the connection and sealing. Usually, high-strength and weather-resistant industrial glues such as silicone adhesives, acrylic glues, and epoxy glues are used. Different glues need to be used in different scenarios to facilitate adaptation, so that the bent cover plate and the sub-cover plate can be stably fixed and bonded.

[0010] In a preferred embodiment, the bent cover plate is fixedly connected to the lower surface of the corresponding post-cast strip with an attached gasket, and the middle of the auxiliary cover plate is welded to the outer surface of the corresponding fixing seat.

[0011] By adopting the above technical solution, the attached gasket is made of soft material. By contacting the post-cast strip and squeezing from above, the post-cast strip and the main cover plate are more attached to each other, thereby ensuring the sealing effect.

[0012] In a preferred embodiment, a side sealing strip is fixedly connected to the outer surface of the auxiliary cover plate on a side away from the movable rack, and fixing nails are welded to the lower surface of the auxiliary cover plate.

[0013] By adopting the above technical solution, the side sealing strip is made of hard rubber material, a counterweight block is set inside the front end, and the outside is closer to the ground to complete the sealing of the side of the equipment. The fixing nails are stuck on the upper surface of the concrete block to form a whole and ensure the construction quality.

[0014] In a preferred embodiment, a concrete block is fixedly connected to the lower surface of the auxiliary cover plate, and a bottom cushion layer is fixedly connected to the outer surface of the concrete block.

[0015] By adopting the above technical solution, after the bottom cushion layer, base plate, supporting steel bars and waterproof steel plate are installed, the steel support mesh is covered and the final concrete blocks are poured to complete the overall integrated forming.

[0016] In a preferred embodiment, a reference plate is fixedly connected to the upper surface of the bottom cushion layer, and a water-stop caulking plate is fixedly connected to the upper surface of the reference plate.

[0017] By adopting the above technical solution, the bottom cushion layer and the reference plate provide a connected construction working surface in the gap of the engineering operation. The neutrality of the water-stop caulking plate makes the middle of the reference plate relatively stressed, forming a longer path when water penetrates in, avoiding a large amount of moisture from entering the lower connection surface.

[0018] In a preferred embodiment, the inner surface of the concrete block is fixedly connected to the water-stop caulking plate with supporting steel bars, and the inner surface of the concrete block is fixedly connected to the upper portion of the water-stop caulking plate with a waterproof steel plate.

[0019] By adopting the above technical solution, the supporting steel bars provide a skeleton for the support of the concrete blocks, ensuring the increase of the supporting stress, and the waterproof steel plates provide a waterproof effect, increasing the durability of the project.

[0020] In a preferred embodiment, an extension strip is welded to the side surface of the main cover plate, and a steel support mesh is fixedly connected to the upper surface of the waterproof steel plate.

[0021] By adopting the above technical solution, the steel support mesh provides a support surface at the top, provides pressure distribution for the upper support, and at the same time protects the overall bearing capacity below, thereby enhancing the durability of the project. When the extension strips are operated on connection surfaces of different lengths, the main cover plates can be plugged in through the extension strips. The connection points are bonded with the same glue as the limit baffle to complete the extension of the construction length.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] 1. The equipment inserts and pulls the auxiliary cover into the main cover. Under the action of the fixed seat, the movable rack and the auxiliary guide plate move relative to the inner surface of the fixed seat. The gear corresponding to the movable rack engages with the movable gear, causing the auxiliary covers on both sides to move inward or outward at the same time to adjust the width to be sealed.

[0024] Second, the inclined surface of the bent cover plate is squeezed against the auxiliary cover plate, and the interaction force of the fixing seat is used to fix the auxiliary cover plate. After completing the seal above the pouring strip, the corresponding channel of the hole on the upper side of the ventilation slot is connected to the corresponding limit baffle on the side of the bent cover plate. After the adjustment is completed, glue is poured through the ventilation slot to complete the connection and sealing. Usually, high-strength and weather-resistant industrial glues such as silicone adhesives, acrylic glues, and epoxy glues are used. Different glues need to be used in different scenarios for easy adaptation, so that the bent cover plate and the auxiliary cover plate are stably fixed and bonded. The fixing nails are stuck on the upper surface of the concrete block to form a whole and ensure the construction quality.

[0025] 3. The overall construction of components is simple and effective, basically consistent with traditional operations, and does not require further study. The sealing effect is obvious, which increases the construction quality of the project. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The equipment inserts and pulls the auxiliary cover plate 4 into the main cover plate 2. Under the action of the fixed seat 5, the movable rack 8 and the auxiliary guide plate 9 move corresponding to the inner surface of the fixed seat 5. The gear corresponding to the movable rack 8 engages with the movable tooth 7, so that the auxiliary cover plates 4 on both sides are displaced inward or outward at the same time to adjust the width to be sealed. The inclined surface of the bent cover plate 3 is squeezed against the auxiliary cover plate 4, and the interaction force of the fixed seat 5 is cooperated to fix the auxiliary cover plate 4 to complete the seal above the post-casting strip 1.

[0035] Reference Figure 1-4 A ventilation groove 10 is provided on the outer surface of the bent cover plate 3 away from the main cover plate 2 , and a limit baffle 11 is fixedly connected to the outer surface of the bent cover plate 3 away from the main cover plate 2 .

[0036] The corresponding channel of the hole at the top of the ventilation slot 10 is connected to the corresponding limit baffle 11 on the side of the bent cover plate 3. After the adjustment is completed, glue is poured through the ventilation slot 10 to complete the connection and sealing. Usually, high-strength and weather-resistant industrial glues such as silicone adhesives, acrylic glues, and epoxy glues are used. Different glues need to be used in different scenarios to facilitate adaptation, so that the bent cover plate 3 and the auxiliary cover plate 4 can be stably fixed and bonded.

[0037] Reference Figure 1-4 The bent cover plate 3 is fixedly connected to the lower surface of the post-casting strip 1 with an attached gasket 12, and the middle of the auxiliary cover plate 4 is welded to the outer surface of the corresponding fixing seat 5 with an auxiliary guide plate 9.

[0038] The attachment gasket 12 is made of a soft material, and by contacting the post-casting strip 1, squeezing the upper portion thereof, the post-casting strip 1 and the main cover plate 2 are more closely attached to each other, thereby ensuring a sealing effect.

[0039] Reference Figure 1-4 A side sealing strip 13 is fixedly connected to the outer surface of the auxiliary cover plate 4 away from the movable rack 8, and a fixing nail 14 is welded to the lower surface of the auxiliary cover plate 4.

[0040] The side sealing strip 13 is made of hard rubber, with a counterweight block set inside the front end, and is closer to the ground on the outside to complete the sealing of the side of the equipment. The fixing nails 14 are stuck on the upper surface of the concrete block 15, so that the whole is formed into one, ensuring the construction quality.

[0041] Reference Figure 1-2 A concrete block 15 is fixedly connected to the lower surface of the auxiliary cover plate 4 , and a bottom cushion layer 16 is fixedly connected to the outer surface of the concrete block 15 .
