Description

Technical Field

[0001] The utility model relates to the technical field of embedded sleeves, and more specifically to an embedded sleeve for construction engineering. Background Art

[0002] The embedded casing used in construction projects is a device that embeds pipes in holes reserved in brick walls, concrete beams, and concrete wall components that need to pass through. It is usually suitable for civil air defense, underground projects, chemicals, steel, tap water, sewage treatment, and other places where pipelines pass through walls and require strict waterproofing. Generally, the diameter of the embedded casing is larger than the diameter of the pipe that needs to pass through the component.

[0003] In daily use, the existing embedded sleeves used in construction projects need to be buried in the poured wall. However, since the existing sleeves need to use external mounting components when in use, it is difficult to remove them during pouring, and the mounting components are also buried inside. Since the mounting components cannot be reused, waste is caused, thereby increasing the operator's use cost.

[0004] In daily use, the embedded casings used in existing construction projects need to be buried in advance. However, when pouring after installation, the embedded casings may shift and need to be reinstalled, which will seriously affect the operator's experience. Utility Model Content

After installing the embedded casing, the embedded casing fixing ring can be disassembled by disassembling the connection between the connecting plate bolt and the octagonal nut, and the embedded casing fixing ring can be taken out for recycling. This effectively saves the use cost of the equipment. The internal movably sleeved threaded sleeve of the embedded casing fixing ring is fixedly connected to the threaded sleeve handle outside the threaded sleeve. The internal movably sleeved bolt column of the threaded sleeve is fixedly connected to the arc-shaped extrusion plate outside the bolt column. This is beneficial in that when position deviation occurs during burial, the bolt column of the threaded sleeve can be controlled to extend and retract by rotating the threaded sleeve handle connected to the threaded sleeve in the embedded casing fixing ring, and then the arc-shaped extrusion plate is controlled by the extension and retraction of the bolt column, thereby controlling the position correction of the embedded casing, thereby effectively optimizing the operator's use experience.

[0007] Furthermore, an extrusion plate stress ring is provided inside the arc extrusion plate, which is conducive to convenient stress treatment of the arc extrusion plate through the extrusion plate stress ring. The outside of the extrusion plate stress ring is fixedly connected to the outer tube of the embedded sleeve, and the outside of the extrusion plate stress ring is provided with an inner tube groove, which is conducive to convenient sleeve installation of the inner tube through the inner tube groove.

[0008] Furthermore, the inner tube groove is internally movably sleeved with an inner tube ring, and the outer portion of the inner tube ring is fixedly connected to the embedded inner tube of the sleeve, and the embedded inner tube of the sleeve can press the inner tube ring against the wall according to the elasticity of the spring.

[0009] Furthermore, the outside of the inner tube of the embedded sleeve is connected to the inner tube spring, and the outside of the inner tube spring is fixedly connected to the spring fixer, which is conducive to providing support when the inner tube spring is contracted and extruded.

[0010] Furthermore, the outer part of the spring holder is fixedly connected to the outer tube of the embedded sleeve, which is conducive to fixing the spring holder on the inner wall through the outer tube of the embedded sleeve to prevent deviation due to the spring.

[0011] Furthermore, a reserved pipeline is provided inside the inner tube of the embedded sleeve, which is conducive to reserving a channel conveniently.

[0012] Furthermore, the exterior of the embedded sleeve fixing ring is fixedly connected to the fixing ring connecting column, and the fixing ring connecting column is conducive to keeping the embedded sleeve fixing rings at both ends on the same horizontal line.

[0013] Technical effects and advantages of the utility model:

[0014] 1. The utility model is provided with a fixing ring connecting plate, which is conducive to fixing the embedded casing fixing ring through the connecting plate bolts sleeved in the fixing ring connecting plate outside the embedded casing fixing ring. After the embedded casing is installed, the embedded casing fixing ring can be removed by disassembling the connection between the connecting plate bolts and the octagonal nut, and the embedded casing fixing ring can be taken out for recycling, thereby effectively saving the use cost of the equipment.

[0015] 2. The utility model is provided with an arc-shaped extrusion plate, which is beneficial for controlling the extension and retraction of the bolt column of the threaded sleeve by rotating the threaded sleeve handle connected to the threaded sleeve in the embedded sleeve fixing ring when position deviation occurs during burial.
