Description

Technical Field

[0001] This invention relates to the field of civil defense basements, specifically to a sealed through-wall sleeve, adhesive injection components, and construction method for civil defense basements. Background Technology

[0002] Civil defense shelters need to be resistant to attacks and biological and chemical gas attacks during wartime, serving as a powerful safeguard for the lives and property of the people. To ensure the ventilation, water supply, and power supply needs of civil defense shelters during wartime, pre-installed sleeves should be installed where pipes pass through the surrounding walls of the shelter. These pre-installed sleeves must be designed to effectively withstand shock waves and biological and chemical gas attacks during wartime.

[0003] Currently, most civil defense basements are designed for conversion between peacetime and wartime use. To ensure the smooth transition between the two, the airtightness and impact resistance of the pre-installed casings must be adequately guaranteed.

[0004] The existing technology CN201610363040.1, "Flexible Waterproof Through-Wall Sleeve Structure and Construction Method for Basement Concrete Exterior Wall," still uses the conventional external welding method for fixing the sleeve, which requires high operational and positional control skills from construction personnel. Furthermore, it does not describe in detail how to use the filling equipment to fill the reinforcing steel components. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this invention.

[0006] A sealed through-wall sleeve for civil defense basement includes a pre-embedded sleeve and a steel reinforcement component, wherein the pre-embedded sleeve is installed inside the steel reinforcement component;

[0007] The outer end of the pre-embedded sleeve is provided with a sealing rib, a stop ring is installed on the sealing rib, and a clamping member is installed on the outer end of the stop ring. The clamping member is suitable for connection with the reinforcing steel member.

[0008] The pre-embedded sleeve includes an inner flange at both ends, an outer shell, and an inner pipe; the inner pipe is adapted to pass through the inner flange and the outer shell, and a filling cavity is adapted to be provided between the outer shell and the inner pipe; and cross holes are opened at both ends of the outer shell.

[0009] This invention features a slanted clamp that connects to the reinforcing steel member, enabling multi-angle connections. The clamp can be tied with wire rope or spot-welded to the corresponding reinforcing steel member. Positioning can be adjusted before installation within the inner pipe, after which epoxy resin is filled into the cavity. Compared to conventional cement mortar, epoxy resin has stronger adhesion and chemical stability. As a reinforcing adhesive, the epoxy resin used is a readily available epoxy resin adhesive.

[0010] In a further technical solution, the gripper includes a bent rod arranged along the edge of the shift ring; the shift ring is inclinedly arranged on the outer cylinder shell.

[0011] An epoxy injection component includes an adjusting rod with sleeves installed at both ends. A cross block is installed at the bottom of the sleeve, and a feed hole is provided at the bottom of the cross block. The filling cavity is suitable for filling with epoxy resin, and the sleeve is suitable for conveying external epoxy resin.

[0012] In a further technical solution, the adjusting rod includes a threaded sleeve, with threaded rods installed at both ends of the threaded sleeve. The threaded rods are adapted to rotate within the threaded sleeve, and the side of the threaded rod facing away from the threaded sleeve is fixedly connected to the sleeve opening tube.

[0014] The end of the hanging rod away from the internal threaded hole is equipped with a hook, which is suitable for connecting to the reinforcing steel member.

[0015] In a further technical solution, fixing blocks are installed at both ends of the threaded sleeve, and the interior of the sleeve tube is inverted conical. In this invention, the two ends of the adjusting rod extend relative to the threaded sleeve along with the threaded rod, and then the upper and lower connections to the reinforcing steel components are achieved through adjustable ball joint rods on the fixing blocks. The structure is simple and highly practical.

[0016] A construction method for a sealed through-wall sleeve and adhesive injection fitting in a civil defense basement includes the following steps:

[0017] Step 1: Complete the binding of the reinforcing steel components and leave space for the installation of the embedded sleeves;

[0018] Step 2: Rotate the clamping device into the pre-embedded sleeve so that the inclined bent rod is connected to the steel reinforcement component. The number of connections should be greater than 3 sets. Weld the bent rod to the corresponding connected steel reinforcement component.

[0019] Step 3: Install the injection molding component. Adjust the two ends of the injection molding component according to the size of the two sets of cross holes on the drawing, and let it pass through part of the steel bar. The cross blocks at both ends are connected to the cross holes, and the cross holes are stepped holes.

[0020] Rotate the ball joint rod on the fixed block and adjust the corresponding hanging rod to connect it to the nearest steel bar. The above operation is performed on both sets of hanging rods.

[0021] Step 4: Install the inner pipe and adjust the distance between the two ends of the inner pipe relative to the reinforcing steel members; connect the outer pipe to the opening of the sleeve pipe and inject epoxy resin into the filling cavity.

[0022] Step 5: Tie the reinforcing bars in other areas;

[0023] Step 6: Install the outer template. There are two sets of outer templates, and the two sets of outer templates are connected to the corresponding inner flanges. Install the outer flanges on the other side of the outer templates. Install locking bolts between the outer flanges and the inner flanges and let them pass through the outer templates.

[0024] Step 7: Install other components and complete the pouring.

[0025] In a further technical solution, the outer flange has a concave opening on one side relative to the outer template, and the concave opening has multiple sets of mounting holes, which are suitable for installing locking screws, and an airbag is installed at the bottom of the concave opening.

[0026] In a further technical solution, the bottom of the concave opening is V-shaped and has an air bladder cavity inside, which is suitable for filling an air bladder. The outer end of the outer flange is provided with an openable and closable inflation port, which is suitable for inflating the air bladder.

[0027] Compared with the prior art, the present invention can achieve the following technical effects:

[0028] This invention features a slanted clamp that connects to the reinforcing steel member, enabling multi-angle connections. The clamp can be tied with or spot-welded to the corresponding reinforcing steel member using wire rope. Positioning can be adjusted before installation within the inner pipe, after which epoxy resin is filled into the cavity. Compared to conventional cement mortar, epoxy resin has stronger adhesion and chemical stability, serving as a reinforcing adhesive.

[0029] In this invention, the two ends of the adjusting rod extend relative to the threaded sleeve along with the threaded rod, and then the upper and lower steel reinforcement components are connected through the adjustable ball joint rod on the fixed block. The structure is simple and highly practical.

[0030] This invention provides a concave opening inside the outer flange, allowing mortar leakage at the connection point with the outer template to flow through the bottom of the concave opening. As the air bladder fills, it forms a connection space with the outer template, thus achieving the casting connection. Attached Figure Description
