[0030] Referring to Figs. 1 to 4 The utility model provides a sleeve fixing device, including device outer frame 01, a plurality of clamp ring 05 of setting in device outer frame 01 inside, the two inner side walls of device outer frame 01 opposite are set with sliding rail 02, and the outer wall of both sides of clamp ring 05 is provided with telescopic screw rod 04, and the outer wall of device outer frame 01 is all set with recess, and sliding rail 02 is communicated with recess, and the end of telescopic screw rod 04 is slidably connected with sliding rail 02, and the end of telescopic screw rod 04 is fixedly arranged in sliding rail 02 through nut 03,

[0031] Sleeve 07 is arranged in clamp ring 05, and sleeve gasket 06 is arranged between sleeve 07 and clamp ring 05.

[0032] Each clamp ring 05 includes two butt-jointed half-ring clamps, the two ends of the half-ring clamps are provided with connecting ear plates, threaded holes are formed in the connecting ear plates, and the two connecting ear plates are fixedly connected by clamp nuts 08.

[0033] The end of telescopic screw rod 04 is threadedly connected with the outer wall of clamp ring 05, the end of telescopic screw rod 04 is provided with a telescopic screw rod rotating cap 09, and the end of telescopic screw rod 04 close to clamp ring 05 is fixed to the outer wall of clamp ring 05 by the telescopic screw rod rotating cap 09.

[0034] Nut 03 is located in the recess.

[0035] Sleeve gasket 06 is made of rubber pad or corrosion-resistant wood support.

[0036] The distance between sleeves 07 can be adjusted through the sliding rail 02 on the device outer frame 01, the telescopic screw rod 04 can be fixed in one direction by using the nuts 03 on the two sides of the sliding rail 02, then the size of the clamp ring 05 is determined according to the size of the sleeve 07 on the drawing, then the two half-ring clamps of the clamp ring 05 are fixed by using the clamp nuts 08, and whether the sleeve is eccentric alignment is determined according to the drawing after the clamp ring 05 is fixed, if it is eccentric alignment, the telescopic screw rod rotating cap 09 on the telescopic screw rod 04 is used to adjust the longitudinal direction of each clamp ring 05, so that the requirements are met.

[0037] As in multi-storey or high-rise buildings, the upper pipe well casing 07 is reduced, the casing gasket 06 can be used to pad inside the clamp ring 05 to avoid replacing the clamp ring 05.

[0038] The telescopic screw 04 slides on the sliding rail 02 on the device outer frame 01, so that the telescopic screw 04, clamp ring 05, etc. can be freely adjusted.

[0039] For the eccentric casing 07 in the pipe well, after adjusting the lateral spacing of the casing 07, the telescopic screw rotating cap 09 can be adjusted to meet the requirements of different casing positions.

[0040] For multi-storey or high-rise buildings, the pipe diameter of the upper casing 07 is reduced, and the casing gasket 06 can be added to the clamp ring 05 to avoid adjusting the telescopic screw 04.

[0041] The device outer frame 01 is made of on-site leftover materials, such as leftover C-shaped steel, angle iron, etc. in the processing area or warehouse. After the device outer frame 01 is assembled, the sliding rail 02 is opened to ensure that the telescopic screw 04 can slide in the sliding rail 02 to adjust the spacing between the telescopic screws 04.

[0042] The telescopic screw 04 is fixed by tightening the screw cap 03 on both sides of the sliding rail 02. The telescopic function of the telescopic screw 04 is realized by the telescopic rod rotating cap 09. By rotating the telescopic rod rotating cap 09, the telescopic screw 04 can be lengthened and shortened. The telescopic screw 04 and the telescopic rod rotating cap 09 are integrated devices. There are reserved clamp ring 05 installation threads on the outside of the telescopic rod rotating cap 09, and the reserved length is consistent with the thickness of the clamp ring 05.

[0043] After the corresponding telescopic screw 04 and clamp ring 05 on both sides of the frame are installed, they are fastened by the clamp nut 08.

[0044] The size of the clamp ring 05 is determined by the size of the casing.

[0045] In multi-storey or high-rise buildings, the pipe diameter of the upper building is generally smaller than that of the lower building. If there is no or insufficient time to replace the corresponding clamp ring 05 on site, the corresponding casing gasket 06 can be added to the clamp ring 05. The casing gasket is easy to be rubber pad or corrosion-resistant wood support.

[0046] Working principle: When a new type of casing fixing device is used in the field, first, the device is processed and manufactured in the processing area or warehouse according to the needs of the site. Field application mainly includes the following two cases:

[0047] (1) The sleeves 07 are all the same size; first, determine the size of each clamp ring 05 according to the drawing, and then determine the spacing between each clamp ring 05 according to the actual requirements. Adjust it using the sliding rail 02. After adjustment, tighten the device with clamp nuts 05 and nuts 03 to prevent movement. If the upper sleeve becomes smaller, the diameter can be changed by adding sleeve gaskets 06 inside the clamp rings 05, thereby avoiding the need to adjust and replace the clamp rings 05 and telescopic rods 04.

[0048] (2) Inconsistent sleeve 07 size: First, determine the size of each clamping ring 05 according to the drawings. Then, determine the spacing between each clamping ring 05 according to actual requirements and adjust it using the sliding rail 02. Determine the longitudinal distance between sleeves 07 according to the drawings. Then, adjust each clamping ring 05 using the telescopic screw 04. After adjustment, tighten the device using the clamping nut 05 and the nut 03 to prevent movement. If the upper sleeve becomes too small, the diameter can be changed by adding a sleeve gasket 06 inside the clamping ring 05, thus avoiding the need to adjust and replace the clamps 05 and the telescopic rod 04.

[0049] After adjusting the device, its position is determined directly on-site using quadrant points. Then, the sleeve 07 is placed directly inside the clamp ring 05 and secured. It's not necessary to position and secure each sleeve individually; once secured on one layer, the next layer is secured in the same manner. This device not only ensures that the sleeves 07 on both upper and lower layers are in the same position but also speeds up construction, avoids the need for later drilling and secondary concrete pouring due to sleeve misalignment, and saves resources.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
