Telescopic sleeve for constructional engineering

ZHOU RENKAI

The invention discloses a constructional engineering telescopic sleeve and aims to solve the problem of pipeline displacement caused by different widths of beams, walls and the like in building construction. The sleeve is composed of an inner sleeve, an outer sleeve, a supporting rod, a lead screw and the like, the length of the sleeve is freely adjusted by rotating the lead screw, and the working principle is that the supporting rod is connected with the lead screw, the lead screw drives the supporting rod to do linear motion when rotating, and therefore the inner sleeve is pushed to do telescopic motion relative to the outer sleeve; the telescopic sleeve has the advantages of being convenient to install, flexible to adjust, good in sealing performance and the like, is particularly suitable for pre-embedding construction in a PC (precast concrete) structure, can conveniently adapt to the distance of a laminated slab extending into a beam by adjusting the length of the sleeve, and ensures the pre-embedding accuracy and sealing performance of the sleeve. The constructional engineering telescopic sleeve is an efficient and reliable pipeline connecting device, and an effective solution is provided for the problem of pipeline displacement in building construction.

本发明公开一种建筑工程伸缩套管，旨在解决建筑施工中因梁墙等宽度不同导致的管道位移问题；该套管由内外套管、撑杆、丝杆等部件组成，通过旋转丝杆实现套管长度的自由调节，其工作原理是，撑杆与丝杆连接，丝杆旋转时带动撑杆进行直线运动，从而推动内套管相对于外套管进行伸缩运动；该伸缩套管具有安装方便、调节灵活、密封性好等优点，特别适用于PC(预制混凝土)结构中的预埋施工，通过调节套管长度，可以方便地适应叠合板伸入梁内的距离，确保套管预埋的准确性和密封性。该建筑工程伸缩套管是一种高效、可靠的管道连接装置，为建筑施工中的管道位移问题提供了有效的解决方案。
