Description

Technical Field

[0001] This application relates to the field of building construction, specifically to a pipe sleeper fixing device for power engineering pipelines. Background Technology

[0002] Pipe supports for power engineering are building accessories used for pipe installation and fixing. Their main function is to support and stabilize pipelines, ensuring that they do not move or deform due to external forces during operation. Pipe supports are typically made of sturdy materials such as concrete, metal, or plastic. Polyethylene pipe supports are inexpensive and easy for construction workers to install. They are usually assembled from prefabricated components with pins, and there are pre-drilled circular holes between the pipe supports after assembly. However, considering their lightweight nature, lack of stable fixing measures, and the potential for pipes to float or shift during concrete pouring, a matching material is considered as a positioning and stabilizing device for the pipe supports.

[0003] Currently, there are no specific fixing measures for the installation of power pipeline supports. Utility models CN 213509637 U and CN 218386564 U provide two different types of anti-buoyancy devices, both of which rely on steel structure frame devices to install and fix the pipeline. Considering the problems of high construction costs, easy corrosion of steel structures, poor preservation effect, and long construction period of such utility models, this technology fixes the support to the ground concrete on the basis of fixing the support to the pipeline, ensuring a tight and firm overall connection.

[0004] After the pipe supports are installed, their bottoms directly contact the concrete base. Considering that pipe supports of the same size cannot meet the required concrete thickness at the bottom of the pipe as specified in the drawings, and that there is no suspension or fixing device for the pipe supports, one existing solution is to design pipe supports of a specific size to ensure that the bottom concrete thickness matches the corresponding pipe support size. However, this cannot solve the problem of the pipes floating or shifting during the pouring of the outer concrete. Another solution is to use a steel frame structure fixedly connected to the base to ensure the pipes are aligned and fixed. This effectively solves the problems of lacking dedicated fixing measures and the pipes floating or shifting during concrete pouring. However, the construction cost is too high, and considering that the steel structure itself is prone to corrosion and has poor preservation, the cost-effectiveness of this solution is low.

[0008] More preferably, the main unit piece has a through hole at its center, and the fastener includes a sleeve and a pull member. The pull member includes a head I-shaped structure and a tail cross-shaped handle. The head I-shaped structure and the tail cross-shaped handle are connected by a rod. The sleeve has a channel for the head I-shaped structure to pass through.

[0009] Furthermore, the diameter of the cross-shaped handle at the tail is larger than the diameter of the sleeve.

[0010] Furthermore, slots are provided at both ends of the connector, the main unit piece, and the end of the vertical connector that connects to the connector, and the pin is inserted into the slot to connect adjacent components.

[0011] Furthermore, the base plate is a groove-shaped structure with side plates on all four sides, and bolt holes are provided on the plate surface.

[0012] Furthermore, the main unit piece has a centrally symmetrical structure, with sidewalls including a plane and an arc-shaped surface. The slot is located on the plane, and the arc-shaped surface is set at a certain distance from the pipe.

[0013] In addition, the slot has an isosceles trapezoidal cross-section that is narrower at the top and wider at the bottom.

[0026] To make the technical means, innovative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.

[0027] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model. They are all illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0028] A pipe sleeper fixing device for power engineering pipelines, such as Figures 1-6 As shown, it includes a ground support structure 1 and a pipe sleeper fixing structure 2. The ground support structure 1 includes a base plate 11 for fixed connection with the ground and a vertical connector 12 provided on the base plate 11. The pipe sleeper fixing structure 2 includes a main unit piece 21, a pin 22 and a connector 23. The pin 22 is used to connect the connector 23 to the main unit piece 21 and the connector 23 to the vertical connector 12. The main unit piece 21 is fixedly connected to the pipe sleeper 3. Several main unit pieces 21 are connected into an integral support piece by the pin 22 and the connector 23. After the support piece is connected to the pipe sleeper, it is supported on the ground by the ground support structure 1. The overall length of the connector 23 is adjustable to adapt to pipe sleepers of different sizes.

[0029] The fastener 24 serves to fix the main unit piece 21 and the tube pillow 3. Specifically, it includes a sleeve 241 and a pull member 242. The pull member 242 includes a head I-shaped structure and a tail cross-shaped handle. The head I-shaped structure and the tail cross-shaped handle are connected by a rod. The sleeve has a channel for the head I-shaped structure to pass through. The sleeve 241 is inserted into the overlapping hole of the perforation 25 and the reserved hole between the adjacent tube pillow. After the head I-shaped structure is inserted and passes through the channel, it is rotated and locked on the outside of the sleeve, forming a lock between the main unit piece 21 and the tube pillow.

[0030] In practice, the diameter of the cross-shaped handle at the tail is larger than the diameter of the sleeve 241. Its main function is to form a two-end locking state with the straight structure at the head.

[0031] In specific implementation, slots 4 are provided at both ends of connector 23, the main unit piece 21 and the end of vertical connector 12 that connects to connector 23. Pins 22 are inserted into slots 4 to connect adjacent components. The length of connector 23 is set as needed.

[0032] In specific implementation, the base plate 11 is a groove-shaped structure with side plates on all four sides and bolt holes on the plate surface. The main unit piece 21 is a centrally symmetrical structure with side walls including flat and arc-shaped surfaces. The slot 4 is located on the flat surface, and the arc-shaped surface is set at a certain distance from the pipe.

[0033] In practice, the slot 4 has an isosceles trapezoidal structure with a narrow top and a wide bottom, and the connector 23 is generally designed as a strip structure to compensate for the insufficient spacing between the main body unit pieces 21.

[0034] In practice, the main unit piece 21 is fixed between the four pipes. Its shape should be adapted to the shape of the gap between the four pipes. Specifically, it includes four arc-shaped surfaces that are adapted to the outer surface of the pipes and a plane located between two pipes. The slot is set on the plane and is used to connect adjacent main unit pieces 21.

[0035] In specific implementation, the ground support structure 1, main unit piece 21, pin 22, and connector 23 are all made of polyethylene material and are named as polyethylene component No. 1, polyethylene component No. 3, pin, and polyethylene component No. 2, respectively. The shape of polyethylene component No. 1 is a hollow cuboid with a bottom. The bottom is fixed to a vertical hollow cuboid with a bottom. Four bolt holes are opened at the bottom of the bottom cuboid. The concrete pad layer is connected by ground anchor bolts to fix polyethylene component No. 1 to the pad layer concrete. The length and width of the vertical cuboid above are selected according to the clear distance of the pipe and the height between the bottom of the pipe rest and the pad layer. The No. 2 polyethylene component is a vertical, bottom-mounted hollow cuboid, with dimensions determined by the clear distance between pipes. Its width is consistent with that of the No. 1 polyethylene component. The thickness of the No. 2 polyethylene component is increased to ensure that the stress requirement is met. The No. 3 polyethylene component is a vertical, bottom-mounted octagonal irregular hollow polygon. The width of the straight part is consistent with that of the No. 2 polyethylene component, while the curved part is an arc curve according to the pipe design. The bottom of the No. 3 component has a pre-drilled hole consistent with the pipe support splicing. It is connected and fixed by a polyethylene joint of the same shape as the hole. The vertical hole is connected to the pad layer by multiple No. 2 and No. 3 components. No. 1, 2 and No. 3 components can be connected and fixed by pins through the pin holes. The pins are consistent with the pipe clamp pins. To further enhance stability, No. 2 component can be selectively used to connect No. 3 component laterally to achieve the fixation and positioning of the pipe support and power pipeline in a suspended state.

[0036] More specifically:

[0037] (1) No. 1 polyethylene component: The shape is a bottom hollow cuboid with a fixed bottom and a vertical bottom hollow cuboid. The bottom of the bottom hollow cuboid has four 10mm holes. The cuboid with reserved holes has a bottom surface with a thickness of 5mm and a side surface with a thickness of 5mm and a height of 20mm. The vertical bottom hollow cuboid has a side surface with a thickness of 5mm and a height of 20mm and a bottom surface with a thickness of 5mm.

[0038] (2) No. 2 polyethylene component: The shape is a vertical hollow cuboid with a bottom. The vertical hollow cuboid with a bottom has a side surface with a thickness of 10mm and a height of 20mm, and a bottom surface with a thickness of 10mm. The width is controlled at about 70mm~100mm according to the net distance of the pipe.

[0039] (3) No. 3 polyethylene component: The shape is a vertical octagonal irregular hollow polygon with a bottom. The width of the straight part is consistent with the width of No. 2 component. The curved part is an arc curve according to the pipe design. The bottom of the middle is reserved with a channel consistent with the pipe pillow splicing. It is connected and fixed by a perforated fastener with the same shape as the channel.

[0042] (6) Fixed assembly pin: Made of polyethylene material with a specially customized cross section that is wide at the top and bottom and narrow in the middle.

[0043] How to use:

[0044] (1) The normal steps of pipeline installation construction: After the earthwork excavation and bedding construction are completed, the placement position of component No. 1 is determined according to the relevant positions of the power pipeline and pipe sleepers. The pipe sleepers are arranged according to the spacing. After the arrangement is completed, M8 buried bolts are used to drill through the bottom hole of component No. 1, and corresponding nuts are used to fix component No. 1.

[0045] (2) Assemble components 2 and 3 in sequence at their corresponding slot positions, and then use pins to fix them in sequence.

[0046] (3) After the first layer of the fixing device is assembled (1, 2 and 3 are assembled into a whole), two rows of pipe pillows are assembled from bottom to top. The reserved holes at the pipe pillow interface correspond to the middle hole of component No. 3, and the perforated fasteners are used for perforation and fixing.

[0047] (4) After the lower two rows of pipe supports are installed, repeat step (2) to fix the upper components 2 and 3 in sequence, and repeat step (3) to fix the whole structure.

[0048] (5) In order to further increase the overall stability of the fixing device, component No. 2 can be used to connect component No. 3 laterally in step (2).
