Description

TECHNICAL FIELD

[0001] The present application relates to the field of building construction, in particular to an indoor pipeline installation structure and method. BACKGROUND

[0002] In conventional construction, especially when wiring and setting up pipelines in the indoor, the problem of pipeline butt joint installation is encountered. In the prior art, the pipeline (such as exhaust pipe, water pipe and the like) is installed on the overhead ceiling in the indoor, and a support is used for installation of high-altitude operation, which has great difficulty in work. When installing the pipeline, a worker generally stands on the corresponding support frame, uses a crane to place the to-be-installed pipeline at one end of the installed pipeline, and then uses two steel wires to tie an outer ring on the outer diameter of the two pipelines respectively, and then the steel wires drawn from the outer ring locking points are tied at the two ends of the hand-operated hoist, and then the hand-operated hoist is operated to reduce the distance between the two locking points, so as to realize the installation between the two pipelines, and then the pipelines are connected by positioning flanges or directly inserted together.

[0003] The above installation method has the problem of inconvenient high-altitude operation installation. When hoisting the pipeline, the worker manually butt joints the pipeline, which may cause inaccurate butt joint. Since the steel wire bears the tension while giving the force to the periphery of the pipeline, the pipeline is prone to deflection. Once the deflection occurs, the two pipe openings will be at a small angle, which is not convenient for butt joint of the pipeline and increases the difficulty of construction. SUMMARY

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] As Figures 1-8As shown, the present application provides an indoor pipeline installation structure, the pipeline is composed of multiple pipe sections 6, the installation structure comprises multiple support frames 1 for detachably fixing the multiple pipe sections 6 and being hingedly connected with each other, the support frame 1 is provided with a limiting rod set for limiting the pipe section 6, at least two hoisting rods 5 for hoisting the pipe section 6, and an abutting assembly for aligning the pipe section 6 is fixed at the hinge position of adjacent support frames 1. In the embodiment, one end of the multiple support frames 1 is hingedly connected together through a rotating shaft. The support rod is a steel wire rope or a threaded rod. Before installation, the pipeline is pre-installed on the ground, the pipe section 6 is installed together with the support frame 1, and the relative fixed state of the pipe section 6 and the support frame 1 is ensured, so that the pipe section 6 and the support frame 1 are kept in a relative fixed state; then the support frame 1 is hoisted, and since the positions of the support frame 1 and the pipe section 6 are kept in a relative fixed state during hoisting, the installation part of the support frame 1 is fixed and unchanged during hoisting, so the position of the pipe section 6 is also determined, thereby facilitating the alignment of the pipe section 6. During installation, one of the support frames 1 is hoisted, and the other support frames 1 and the pipe section 6 are rotated around the rotating shaft 2, but the pipe section 6 is in the same vertical plane, and when the other support frame 1 is hoisted, it only needs to be kept in a horizontal position, without the need to align in other directions, thereby reducing the process and procedure of pipeline alignment during installation, and the installation is very convenient. The abutting assembly is used, when the support frame 1 and the pipe section 6 are kept in a horizontal state, the pipe section 6 is directly pushed to move in the horizontal direction, and the axes of the two pipe sections 6 are in the same straight line when they are in a horizontal state.

[0027] As shown in Figure 3 and Figure 4 , the abutting assembly comprises a first U-shaped rod 10 and a second U-shaped rod 9 fixed on adjacent two support frames 1 respectively, the second U-shaped rod 9 is provided with a slot on the outer side for inserting the first U-shaped rod 10, the slot is arranged along the length of the second U-shaped rod 9, and the space for the adjacent two pipe sections 6 to pass through is formed between the first U-shaped rod 10 and the support frame 1 and between the second U-shaped rod 9 and the other support frame 1 respectively. The first U-shaped rod 10 and the second U-shaped rod 9 are arranged at the hinge position of the support frame 1, so that the pipe sections 6 can be directly inserted with each other when the pipe sections 6 are abutted. Due to the shape of the first U-shaped rod 10 and the second U-shaped rod 9, the pipe sections 6 can be vertically and horizontally limited when they are inserted with each other, so that the adjacent two pipe sections 6 can be accurately and correctly abutted and fixed.

[0028] Preferably, as shown in Figure 1 and Figure 2As shown, the outer periphery of the same position of each pipe section 6 is fixed with a positioning flange, the limiting rod set includes two pairs of rod members for the positioning flange, each pair of rod members includes two first fixed rods 3 respectively located on both sides of the support frame, the distance between the two first fixed rods 3 is equal to the diameter of the pipe section 6, and the distance between the two pairs of rod members is equal to the thickness of the positioning flange. When installing, the flange of the pipe section 6 is clamped between the two pairs of fixed rods 3, thereby limiting the transverse position of the pipe section 6, so that the pipe section 6 cannot move in the axial direction of the pipe section 6. The pipe section 6 is directly placed between the two fixed rods 3 of each pair of rod members, so that the two fixed rods 3 limit the longitudinal direction of the pipe section 6. Further, the number of limiting rod sets and flanges includes at least two sets, and the flanges of the limiting rod sets are correspondingly arranged, and the at least two sets of limiting rod sets and flanges are preferably arranged on both sides of the pipe section 6.

[0029] In the second embodiment, the limiting rod set includes two oppositely arranged second fixed rods, and the distance between the two second fixed rods is not less than the diameter of the pipe section 6. In the second embodiment, when the butt joint assembly is used, the pipe section 6 needs to be slid and butt jointed with the end of another pipe section 6 when hoisted to a horizontal state, so that the pipe section 6 installed later cannot be fixed between the support frame 1, but can be limited. In the pre-installation, the limiting flange 4 does not need to be welded on the pipe section 6, only the second fixed rod needs to be welded on the support frame 1, and the longitudinal direction of the pipe section 6 is limited, and in the axial direction of the pipe section 6, the pipe section 6 can slide.

[0030] Preferably, as shown in the drawings, Figures 5-8 As shown, the butt joint assembly includes a guide rail fixed to the hinged end of the support frame 6 and arranged in the axial direction of the support frame 6, and a rotating flange 13 for fixing the butt joint end of the pipe section 6 to be butt jointed, the guide rail extends out of the support frame 6 and forms an extension, the rotating flange 13 is pivoted with a sliding shaft 8 which can slide along the guide rail, the axis direction of the guide rail is the same as the axis direction of the pipe section 6 which has been hoisted, the sliding shaft 8 is located on the diameter extension line of the pipe section 6, and the end of the guide rail is aligned with the position of the rotating shaft 2. The position of the guide rail coincides with the axis of the pipe section 6, when the sliding shaft 8 slides to the end of the guide rail, the sliding shaft 8 can rotate in the guide rail to match the hinged rotation of the support frame 1, and the pipe section 6 is kept at the same height as the axis of the adjacent pipe section 6, so that when butt jointed, deviation is avoided.

[0031] Preferably, the butt joint assembly further comprises a fixing flange for fixing to the pipe joint pipe opening, the fixing flange 11 is fixed with a guide plate 12, and the guide rail is arranged on the guide plate 12. The guide plate 12 is fixed to the support frame 1 which has been hoisted, and extends a small part along the axial direction of the pipeline, so that the end of the guide rail will not pass out of the guide plate 12, and the guide plate 12 provides a support point for the sliding shaft 8, so that the sliding shaft 8 can slide and rotate at the same time.

[0032] Preferably, the number of the guide plates 12 is two, the distance between the two guide plates 12 is adapted to the diameter of the pipe joint 6, the number of the sliding shafts 8 is two and corresponds to the two guide plates 12 one by one, the two sliding shafts 8 are located on the same diameter of the rotating flange 13, and the distance from the guide rail to the support frame 1 is adapted to the radius of the pipe joint 6. The two guide plates 12 are clamped on both sides of the pipe joint 6, one end of each guide plate 12 is fixed to the fixing flange 11, and the butt joint of the two pipe joints 6 is realized by the sliding of the sliding shaft 8 of the adjacent pipe joint 6 along the guide rail. The distance from the guide rail to the support frame 1 is equal to the radius of the pipe joint 6.

[0033] On the other hand, the present application also provides an indoor pipeline installation method, comprising the following steps: providing an indoor pipeline installation structure as described above; arranging a plurality of pipe joints 6 on a plurality of support frames 1 one by one, and limiting the pipe joints 6 on the corresponding support frames 1 by the limiting rod group; hoisting one of the support frames 1 by the hoisting rod 5; hoisting the adjacent support frame 1, and aligning the two pipe joints 6 by the butt joint assembly; fixing the butt joint of the two adjacent pipe joints 6; and sequentially butt joining all the pipe joints 6 in this way; and removing the support frame 1.

[0034] Before installation, the support frame 1 and the pipe joint 6 can be directly placed on the ground for pre-installation, and the plurality of support frames 1 are hingedly connected by the rotating shaft, and the adjacent pipe joints 6 are not fixed or connected, and when hoisting, the method of installing by hoisting the support frame 1 in sections is adopted, when the first support frame 1 is hoisted, the other support frames 1 are in an inclined state, as shown in Figure 2 , the two support frames 1 only have a rotating inclination in the vertical direction (i.e. the two support frames 1 will rotate relative to each other, and one of the support frames 1 is in an inclined state), and remain in the same vertical plane in other directions. After one of the support frames 1 is hoisted, the other support frame 1 is hoisted in the same way, and during the hoisting process, the support frame 1 gradually remains horizontal, so that the end portions of the two pipe joints 6 are clamped together and remain in a horizontal state, as shown in Figure 1 , so that the two pipe joints 6 can be connected together by bolts, and the two pipe joints 6 can be installed.

[0035] Preferably, the docking assembly comprises a first U-shaped rod 10 and a second U-shaped rod 9 fixed to two adjacent support frames respectively, the second U-shaped rod 9 is provided with a slot on the outer side, the slot is arranged along the length of the second U-shaped rod 9, the first U-shaped rod 10 and the support frame 1 and the second U-shaped rod 9 and the other support frame 1 form a space for the adjacent two end pipe sections 6 to pass through respectively; when fixing the pipe sections 6 on the support frames 1, the pipe sections 6 are arranged in the space between the first U-shaped rod 10 and the support frame 1, and the adjacent pipe sections 6 are arranged in the space between the second U-shaped rod 9 and the support frame; when the two pipe sections 6 are aligned by the docking assembly, the first U-shaped rod 10 of the pipe section 6 is inserted into the slot of the second U-shaped rod 9 of the adjacent pipe section 6. When the support frames 1 and the pipe sections 6 are pre-installed on the ground, the first U-shaped rod 10 and the second U-shaped rod 9 are welded on the two support frames 1 respectively.

[0036] During hoisting, when the two support frames 1 are kept in a horizontal state, the first U-shaped rod 10 can be clamped into the second U-shaped rod 9, and the two support frames 1 are limited, so that the two support frames 1 are kept in a horizontal state. It is ensured that the two pipe sections 6 are in the same straight line during hoisting, which facilitates the installation of the two pipe sections 6.

[0037] Preferably, the docking assembly comprises a guide rail fixed to the hinged end of the support frame 6 and arranged axially along the support frame 6, and a rotating flange 13 for fixing to the docking end of the pipe section 6 to be docked, the guide rail extends out of the support frame 6 and forms an extension, and the rotating flange 13 is pivoted with a sliding shaft 8 which can slide along the guide rail; when the two pipe sections 6 are aligned by the docking assembly, the sliding shaft 8 slides along the guide rail until the two pipe sections 6 are aligned.

[0038] The sliding shaft 8 will not fall out of the sliding groove 7, and the clamping between the rotating shaft and the sliding groove 7 ensures that the pipe section 6 will not fall off the support frame 1 when it is inclined. During hoisting, the end of the other pipe section 6 can rotate between the two guide plates 12. During rotation, the sliding shaft 8 and the rotating shaft are in the same vertical plane (because the sliding shaft 8 can slide in the sliding groove 7, its position is variable), and during rotation, it can be ensured that the rotating shaft center and the rotating state of the pipe section 6 and the support frame 1 remain the same. When hoisting one of the support frames 1, the state of the docking assembly is as follows Figure 8As shown, one of the support frames 1 and pipe sections 6 is first hoisted, and a fixed flange 11 is welded onto them. The fixed flange 11 is welded to the support frame 1 via a fixing rod 3, thus limiting the position of the pipe section 6. However, the pipe section 6 on the other support frame 1 cannot be fixed to it. This is because when using the docking assembly, when the pipe section 6 is hoisted to a horizontal position, it needs to slide and dock with the end of another pipe section 6. Therefore, the subsequent pipe section 6 cannot be connected to the support frame 1, but it can be limited. During pre-installation, it is not necessary to weld the limiting flange 4 onto the pipe section 6; simply welding the fixing rod 3 to the support frame 1 is sufficient to limit the front and rear sides of the pipe section 6. In the axial direction of the pipeline, the pipe section 6 can slide.

[0039] When hoisting pipe section 6 to a horizontal position, as follows Figure 5 As shown in the diagram, slide inwards (i.e. Figure 5 (As indicated by the arrow in the image), the ports of the two pipe sections 6 can be directly aligned and snapped together. During hoisting operations, there is no need to position the pipes, making installation very convenient.

[0040] This invention solves the technical problem of inaccurate pipe connection during indoor ceiling installation by employing a support frame, a limiting rod assembly on the support frame, and a connection component. This invention also addresses the issue of pipe misalignment during high-altitude operations, improving installation accuracy, reducing construction difficulty, and increasing construction efficiency.

[0041] All parts not described in this invention are the same as or can be implemented using existing technologies. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
