Description

Technical Field

[0001] The invention relates to the technical field of building engineering, and in particular to a telescopic sleeve used in a building construction site, especially in a PC (precast concrete) structure, which is convenient to pre-embed, has a length adjustment function and has a good installation effect. Background Art

[0002] In the process of building construction, in order to ensure that the equipment pipelines can pass through the beams and walls smoothly, it is usually necessary to pre-embed the casing in advance. However, with the widespread application of PC structures in the construction field, the traditional method of pre-embedding the casing has encountered challenges. Since the composite panels in the PC structure will extend into the beams for a certain distance (usually 1-2 cm), it is difficult to pre-embed the casing, which is prone to problems such as no film adhesion and poor sealing, affecting the construction quality and efficiency. Summary of the invention

[0003] In view of the problems existing in the prior art, the present invention aims to provide a telescopic sleeve for construction engineering which can be conveniently embedded in a PC structure, has a length adjustment function and has a good installation effect.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A telescopic sleeve for construction engineering,

[0006] It includes an inner sleeve, an outer sleeve, a support rod, a screw rod and a push rod;

[0007] The inner casing is used to accommodate and protect the equipment pipes or lines passing through, and the outer casing is coaxially arranged outside the inner casing to provide additional structural support and protection;

[0008] The support rod is rotatably connected to the screw rod to transmit force and push the inner sleeve to move;

[0009] The screw rod is rotated to adjust its length and drives the support rod and the push rod to move;

[0010] The push rod is movably connected to the support rod and is used to push the inner sleeve to move outward.

[0011] Furthermore, the movable connection is a detachable connection, so that the push rod and the support rod can be easily separated and reassembled.

[0012] Furthermore, it also includes a pressure cap, which is rotatably connected to the support rod. A sleeve with a retaining spring is fixedly connected to the pressure cap. The sleeve can accept one end of the screw rod for insertion and is locked by the retaining spring, thereby preventing the pressure cap and the support rod from falling off the screw rod.

[0013] Furthermore, the insertion end of the screw rod adopts a round head design so that it can be smoothly inserted into the sleeve and clamped by the retaining spring.

[0014] Furthermore, the outer sleeve is provided with a firmly fixed nut, and is matched with a screw rod. The opening and closing degree of the support rod and the telescopic length of the inner sleeve are adjusted by rotating the screw rod up and down through the screw nut.

[0015] Furthermore, a pipe cap is provided at the end of the inner sleeve to seal the opening of the inner sleeve to prevent debris from entering; at the same time, a sealing rubber ring is provided at the gap between the outer sleeve and the inner sleeve to ensure the sealing of the telescopic sleeve.

[0016] Beneficial effects of the present invention:

[0017] 1. Convenient installation and construction: Through the design of the telescopic sleeve, it can be easily placed in the beam and wall, and the end of the inner sleeve can be adjusted to fit the template to improve the appearance effect;

[0018] 2. Adapt to PC structure: In PC structure, the length of the sleeve can be adjusted to adapt to the distance of the composite plate extending into the beam, ensuring the accuracy and sealing of the pre-embedded sleeve;

[0019] 3. Economical and practical: components such as screw rods, support rods and push rods can be recycled, reducing construction costs;

[0020] 4. Improve construction efficiency: The length of the telescopic sleeve is less than the width of the beam and wall during installation, which facilitates the rapid installation and disassembly of the formwork, thereby speeding up the construction progress. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example:

[0032] The construction engineering telescopic sleeve of the present invention comprises an inner sleeve, an outer sleeve, a support rod, a screw rod and a push rod, and has the following specific features:

[0033] Inner casing 10: used to contain and protect the equipment pipes or lines passing through;

[0034] Outer sleeve 20: coaxially arranged outside the inner sleeve 10 to provide additional structural support and protection;

[0035] Support rod 30: rotatably connected to screw rod 40, used to transmit force and push inner sleeve 10 to move;

[0036] Screw rod 40: The length is adjusted by rotation, and the support rod 30 and the push rod 50 are driven to move. The insertion end of the screw rod 40 is designed with a round head so that it can be smoothly inserted into the sleeve 70 and clamped by the retaining spring.

[0037] Push rod 50: movably connected to the support rod 30 (detachable), used to push the inner sleeve 10 to move outward.

[0038] In addition, the following details are included:

[0039] The pressure cap 60 is rotatably connected to the support rod 30 , and a sleeve 70 with a retaining spring is fixedly connected to the pressure cap 60 . The sleeve 70 can receive one end of the screw rod 40 for insertion and is locked by the retaining spring, thereby preventing the pressure cap 60 and part of the support rod 30 from falling off from the screw rod 40 .

[0040] Nut 80: The outer sleeve 20 is provided with a firmly fixed nut 80, which is matched with the screw rod 40. The opening and closing degree of the support rod 30 and the telescopic length of the inner sleeve 10 can be adjusted by rotating the nut 80.

[0041] Sealing structure: A pipe cap 90 is provided at the end of the inner sleeve 10 to seal the opening of the inner sleeve 10 to prevent debris from entering; at the same time, a sealing rubber ring 100 is provided at the gap between the outer sleeve 20 and the inner sleeve 10 to ensure the sealing of the telescopic sleeve.

[0042] The telescopic sleeve of the present invention is screwed clockwise through the screw rod support rod, and the screw rod pushes the support rod outward downward through the pressure cap, so that the two sides of the inner sleeve are pushed, so that the sleeve can be closely attached to the template; then the sleeve is fixed, and the screw rod is screwed counterclockwise until the end of the screw rod and the sleeve on the pressure cap fall off, and the nut on the outer sleeve is sealed. The screw rod is well preserved and can be recycled. In addition, after the template is removed from the beam and wall, the pipe cap is cut open, and the support rod part inside the sleeve is taken out and can be recycled, which is economical and practical, and is easier to install for the currently used PC structure. When installing, the length of the telescopic sleeve is less than the width of the beam and the wall, thereby improving construction efficiency. At the same time, the length of the sleeve can be adjusted in the beam, so that the end of the sleeve can be film-coated, which has a better appearance effect.

[0043] The telescopic sleeve of the present invention is particularly suitable for construction sites, especially when the sleeve is embedded in a PC (precast concrete) structure. By adjusting the length of the telescopic sleeve, the distance of the composite plate extending into the beam can be easily adapted to ensure the accuracy and sealing of the embedded sleeve. At the same time, the telescopic sleeve also has the advantages of easy installation, economical and practical, etc., which can reduce construction costs and improve construction efficiency.

[0044] In summary, the telescopic sleeve of the present invention realizes the adjustability of the sleeve length through the cooperation of the support rod, the screw rod and the push rod, which facilitates the pre-embedded construction in the building construction. At the same time, the reliability and durability of the telescopic sleeve are ensured by taking sealing and protection measures.

[0045] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
