Description

Technical Field

[0001] The utility model relates to the field of pipeline construction, in particular to a fixed structure used for pipeline construction. Background Art

[0002] In the construction and installation of pipeline projects in the construction industry, the fixing, installation and anti-loosening of pipeline interfaces are difficult, the construction speed is slow, and the efficiency is low. The sealing and drainage effect of the pipeline project cannot be guaranteed, which leads to problems such as loosening and water seepage at the pipeline interface of the pipeline project, affecting the installation and drainage efficiency of the pipeline project. The traditional method of fixing pipeline interfaces is mainly to use pouring concrete sealing. This method has slow construction speed, low template installation efficiency, and difficulty in removing the template. It cannot fully meet the needs of on-site construction and is difficult to promote and use on a large scale.

[0003] Specifically, for the upper pipe and the lower pipe that need to be connected, the existing construction method must first solve the problem of aligning the pipe openings, and then pour concrete at the pipe openings to seal the pipe openings between the upper pipe and the lower pipe. During the entire construction process, the efficiency of aligning the pipe openings is low. Secondly, after the concrete sealing is completed, since there is no external clamping force to tighten the pipe openings between the upper pipe and the lower pipe in subsequent use, once the concrete sealing effect is not good, it will cause water seepage problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a fixing structure for pipeline construction which can always lock the upper pipeline and the lower pipeline, thereby effectively improving the sealing performance between the upper pipeline and the lower pipeline.

[0005] The utility model solves the technical problem by adopting the following technical scheme: a fixed structure for pipeline construction, comprising an upper pipeline and a lower pipeline to be connected, comprising a long fixed rod, an upper pipe fixing cylinder and a lower pipe fixing cylinder, the axis of the upper pipe fixing cylinder is coaxially arranged with the axis of the lower pipe fixing cylinder, the upper pipe fixing cylinder is sleeved and arranged on the outer periphery of the upper pipeline, the lower pipe fixing cylinder is sleeved and arranged on the outer periphery of the lower pipeline, the upper pipe fixing cylinder and the lower pipe fixing cylinder are connected with the long fixed rod to form an integrated structure, and the spacing between the upper pipe fixing cylinder and the lower pipe fixing cylinder is adjustable in the direction along the long fixed rod.

[0006] Furthermore, the long fixing rod is a long rod control bolt, and the side walls of the upper tube fixing cylinder and the lower tube fixing cylinder are provided with long rod clamping grooves matching the long rod control bolt along the axial direction, and the long rod control bolt is clamped in the long rod clamping grooves.

[0007] Furthermore, the inner wall of the long rod clamping groove of the upper tube fixing cylinder is provided with an internal thread matching the thread of the long rod control bolt.

[0008] Furthermore, the inner wall of the long rod clamping groove of the lower tube fixing cylinder is provided with an internal thread matching the thread of the long rod control bolt.

[0009] Furthermore, the side wall of the upper tube fixing cylinder is respectively provided with an adjustment groove and a fixing hole in a direction perpendicular to the axis, the axis along the extension direction of the adjustment groove intersects with the center of the fixing hole, and the adjustment bolts are provided in the adjustment groove and the fixing hole.

[0010] Furthermore, the side wall of the lower tube fixing cylinder is respectively provided with an adjustment groove and a fixing hole in a direction perpendicular to the axis, the axis of the adjustment groove along the extension direction of the adjustment groove intersects with the center of the fixing hole, and the adjustment bolts are provided in the adjustment groove and the fixing hole.

[0011] The beneficial effects of the utility model are as follows: in actual use, the upper tube fixed cylinder is sleeved and arranged on the outer periphery of the upper pipe, and the lower tube fixed cylinder is sleeved and arranged on the outer periphery of the lower pipe. Subsequently, the upper tube fixed cylinder and the lower tube fixed cylinder are moved toward each other to ensure that the pipe openings between the upper pipe and the lower pipe are aligned and pressed, and then the spacing between the upper tube fixed cylinder and the lower tube fixed cylinder is locked and fixed. Finally, concrete pouring is performed. The device has a flexible structure and is easy to operate, which reduces labor costs and labor intensity, greatly improves the construction efficiency and interface construction quality of pipeline projects, ensures the drainage effect and service life of pipeline projects, and is particularly suitable for pipeline construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 is a schematic diagram of the plate used to make the fixed cylinder.

[0013] Figure 2 It is a structural schematic diagram of an embodiment of the utility model.

[0014] Markings in the figure are: adjustment slot 1, long rod slot 2, fixing hole 3, adjustment bolt 4, long fixing rod 5, lower tube fixing cylinder 6, upper tube fixing cylinder 7. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1 and Figure 2 The embodiment of the fixed structure for pipeline construction shown in FIG. Figure 1 The material for making the fixed cylinder can be a flexible plastic strip. Figure 2 The lower tube fixing cylinder 6 or the upper tube fixing cylinder 7 is included in the flexible plastic belt. After the flexible plastic belt is rolled into a cylindrical shape, the main body shape of the lower tube fixing cylinder 6 or the upper tube fixing cylinder 7 is formed. Figure 1In the flexible plastic belt, an adjustment groove 1 is provided on the left side, and the adjustment groove 1 extends in the horizontal direction. Among them, the axis of the adjustment groove 1 along the extension direction of the adjustment groove 1 intersects with the center of the fixing hole 3. A fixing hole 3 is provided on the right side of the flexible plastic belt. After the flexible plastic belt is curled into a cylindrical shape, the fixing hole 3 and the adjustment groove 1 are overlapped up and down, and then the adjusting bolt 4 is passed through the fixing hole 3 and the adjusting groove 1 and the above-mentioned cylindrical state is locked, thereby ensuring the shape stability of the lower tube fixing cylinder 6 or the upper tube fixing cylinder 7. When it is necessary to adjust the diameter of the lower tube fixing cylinder 6 or the upper tube fixing cylinder 7, loosen the adjusting bolt 4, and then let the adjusting bolt 4 in the fixing hole 3 move along the direction of the adjusting groove 1, so as to obtain a fixed cylinder with a larger or smaller diameter. Therefore, the present device can adapt to the situation of connecting two pipes with inconsistent calibers.

[0017] After obtaining the lower tube fixing cylinder 6 and the upper tube fixing cylinder 7, the lower tube fixing cylinder 6 and the upper tube fixing cylinder 7 are then connected as one through the long fixing rod 5. Figure 1 The two long rod slots 2 are arranged in the vertical direction after curling, and the two long fixed rods 5 are respectively arranged in the long rod slots 2, so that the long rod slots 2 restrict the long fixed rods 5. One end of the long fixed rod 5 can be fixed in the long rod slot 2 of the lower tube fixed cylinder 6, and the other end of the long fixed rod 5 can be slidably arranged in the long rod slot 2 of the upper tube fixed cylinder 7. When fixing is required, the distance between the lower tube fixed cylinder 6 and the upper tube fixed cylinder 7 is fixed by a nut, so as to prevent the lower tube fixed cylinder 6 and the upper tube fixed cylinder 7 from cracking and leaking in the sealed pipe opening between the lower tube fixed cylinder 6 and the upper tube fixed cylinder 7 due to the back movement between the lower tube fixed cylinder 6 and the upper tube fixed cylinder 7 in subsequent use.

[0018] In addition, in order to adjust the distance between the lower tube fixing cylinder 6 and the upper tube fixing cylinder 7, such a solution can be selected: the inner wall of the long rod slot 2 of the upper tube fixing cylinder 7 is provided with an internal thread matching the thread of the long rod control bolt. By rotating the long fixing rod 5, the upper tube fixing cylinder 7 is moved along the long fixing rod 5, and the distance between the lower tube fixing cylinder 6 and the upper tube fixing cylinder 7 is adjusted. Similarly, the inner wall of the long rod slot 2 of the lower tube fixing cylinder 6 can also be provided with an internal thread matching the thread of the long rod control bolt. In order to ensure that the corresponding thread matching part can have a longer service life, anti-rust paint can be applied to prevent the bolt from rusting.
