Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a protective device for pre-embedded sleeves. Background Technology

[0002] During the installation and layout phase of the pre-embedded external wall sleeves for electromechanical installation, the sleeve openings need to be sealed with tape to protect the finished product and prevent contamination of the pipelines during pouring. This method has the following drawbacks: 1. Removing the tape will generate a large amount of plastic waste, which is detrimental to environmental protection.

[0003] 2. Before pouring the reserved external wall sleeve, the sleeve must be reinforced with steel bars and welded to prevent the sleeve from shifting during pouring.

[0004] 3. After the formwork is removed, the external wall sleeves need to be temporarily sealed with asphalt hemp + expansive cement + sealant to facilitate the backfilling of the civil engineering outside and reduce leakage in the sleeve gaps. However, this construction method has the potential for leakage, and some reserved external wall sleeves may still leak.

[0005] 4. The subsequent demolition process is troublesome, and the tape mixed in with the concrete is not easy to clean. Utility Model Content

[0006] This invention discloses a protective device for pre-embedded sleeves. This device can avoid fixing the pre-embedded sleeves to steel bars, eliminate the need for temporary sealing of gaps after formwork removal, prevent leakage, and prevent environmental pollution during subsequent removal. The device is also reusable.

[0007] To achieve the above objectives, the technical solution of this invention is as follows: A protective device for pre-embedded sleeves includes a cap body with one end sealed and the other end open. The cap body is connected to the outer wall wooden formwork through a rotary connection mechanism. The outer wall of the cap body is provided with an annular groove for connecting with the rotary connection mechanism.

[0008] Preferably, the outer shape and inner cavity of the cap body are both cylindrical, and the diameter of the inner cavity is the same as the diameter of the pre-embedded outer wall sleeve port.

[0011] Preferably, the rotary connection mechanism includes a rotary ring rotatably connected in the annular groove. The outer edge of the rotary ring protrudes out of the annular groove, and multiple connecting blocks are evenly distributed around the axis on the side of the protruding part facing the closed end of the cap body. The upper end of the connecting blocks is provided with screw holes.

[0012] Preferably, the rotating ring is made of metal, and the left and right sidewalls of the rotating ring are slidably connected to the inner walls of the first limiting ring and the second limiting ring, respectively.

[0013] Preferably, the outer surface of the connecting block, the outer surface of the closed end, and the outer surface of the first limiting ring are coplanar.

[0017] The following is a detailed description of the embodiments of the present invention in a step-by-step manner. This description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0018] In the description of this invention, it should be noted that the terms "upper," "lower," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this invention.

[0019] The basic implementation of this novel invention is as follows: a pre-embedded sleeve finished product protection device, such as... Figure 1-4 As shown, the cap body 1 includes a cap that is sealed at one end and open at the other end. The cap body 1 is connected to the outer wall wooden template 3 through a rotary connection mechanism. The outer wall of the cap body 1 is coaxially provided with an annular groove for connecting with the rotary connection mechanism.

[0020] In this embodiment, as Figure 1-4 As shown, the outer shape and inner cavity of the cap body 1 are both cylindrical, and the diameter of the inner cavity is the same as the diameter of the port of the pre-embedded outer wall sleeve 2, which makes it easy to directly insert it into the sleeve port to achieve the sealing at the port.

[0021] In this embodiment, as Figure 1-4 As shown, the cap body 1 includes a cylindrical metal shell with one end sealed, and a first rubber layer (not shown in the figure) is bonded to the inner surface of the metal shell, which is beneficial for sealing the outer wall of the sleeve.

[0022] In this embodiment, as Figure 1-4 As shown, the annular groove includes a first limiting ring 13 and a second limiting ring 11 coaxially welded to the outer wall of the metal shell. The first limiting ring 13 and the second limiting ring 11 form an annular groove. The outer wall of the second limiting ring 11 facing the open end 16 of the cap body 1 is bonded with a second rubber layer (not shown in the figure), which facilitates sealing the gap between the sleeve and the concrete and prevents leakage.

[0023] In this embodiment, as Figure 1-4 As shown, the rotary connection mechanism includes a rotating ring 12 rotatably connected within an annular groove. The outer edge of the rotating ring 12 protrudes beyond the annular groove, and multiple connecting blocks 14 are evenly distributed around an axis on the side of the protruding portion facing the closed end 17 of the cap body 1. Each connecting block 14 has a screw hole 15 at its upper end. To reduce the difficulty of drilling holes in the wooden template, a rotating ring is provided. That is, after drilling holes in the wooden template towards the target position, the rotating ring can be rotated to align the screw holes with the holes on the wooden template, and then the screws can be used to fix it to the connecting blocks. Then, based on the position of the screws on the surface of the wooden template, the remaining drilling positions are located. This reduces the difficulty of connecting the wooden template to the cap body. (See reference...) Figure 1 Partial view of the connection between the screw (not marked in the figure) and the connecting block.

[0024] In this embodiment, as Figure 1-4 As shown, the rotating ring 12 is made of metal material, and the left and right sidewalls of the rotating ring 12 are slidably connected to the inner walls of the first limiting ring 13 and the second limiting ring 11, respectively.

[0025] In this embodiment, the outer surface of the connecting block 14, the outer surface of the closed end 17, and the outer surface of the first limiting ring 13 are coplanar.

[0026] In order to improve the connection strength between the cap body and the first rubber layer and the second rubber layer, a number of pull-out protrusions inserted into the first rubber layer or the second rubber layer can be uniformly arranged on the inner or outer wall of the cap body.

[0027] The working principle of this new type: like Figure 1 As shown, two cap bodies are respectively fitted onto both ends of the pre-embedded external wall sleeve 2 (only one end is shown in the figure) to seal the ends of sleeve 2. After the wooden template is initially fixed, holes are drilled on one side of the connecting block. The rotating ring is rotated to align the screw holes with the drilled holes. Screws passing through the holes are then connected to the screw holes on the connecting block. After the rotating ring is initially fixed, the remaining holes are drilled according to the shape and size of the rotating ring, and screwed to the screw holes on the other connecting blocks. At this point, there is no need to weld steel bars, and the outer end of the sleeve is fixed relative to the wooden template, which can prevent the sleeve from shifting during the pouring process. After the external wall is poured and formed, this new type is directly embedded into the concrete, avoiding secondary sealing of the sleeve gaps. During subsequent removal, simply rotate the rotating ring to dislodge the concrete embedded between the adjacent connecting blocks, and then pull out the cap body. After simple cleaning, this new type can be reused, saving costs and avoiding environmental pollution.
