Description

Technical Field

[0001] This utility model relates to a gas riser bracket for urban areas. Background Technology

[0002] In urban gas supply systems, the installation of gas risers is crucial, as they are the key component connecting ground-level gas pipelines to the gas appliances of users on each floor.

[0003] As a key support component of gas pipeline systems, gas riser brackets are closely related to the development of urban gas engineering, the increasing complexity of building environments, and rising safety requirements. Gas riser brackets provide stable support for gas risers, ensuring their safety and stability during long-term use. Simultaneously, these brackets facilitate worker operation and improve work efficiency during gas pipeline maintenance and repair. Common bolt-connected brackets consist of the bracket body, bolts, and nuts. The bracket is fixed to the wall using bolts, and then the gas riser is installed on the bracket. This type of bracket relies on the tightening force of the bolts to ensure the stability of the connection. However, these common brackets all have certain limitations in practical applications.

[0004] Existing gas riser brackets have many problems. Common bolt-connected brackets require precise drilling during installation. Inaccurate drilling can lead to installation difficulties, wasting time and manpower. Furthermore, during riser purging and subsequent operation and maintenance, removing the riser end plug requires disassembling the bracket, increasing the difficulty of operation and maintenance. Utility Model Content

[0005] The problem this utility model aims to solve is to provide a gas riser bracket for urban areas, which reduces the labor and material costs during installation and maintenance through a unique design and innovative technical solution. This riser bracket allows for the removal of riser plugs, purging, and slag removal for inspection and maintenance without dismantling the support structure, by adjusting nuts and bolts.

[0006] The technical solution provided by this utility model is: a town gas riser bracket, including a support, a cross brace and an inclined brace located below the cross brace. One end of the cross brace is connected to the support, and both ends of the inclined brace are connected to the other ends of the support and the cross brace respectively to form a triangular structure. The cross brace has support bolt holes perpendicular to the horizontal plane, and the cross brace has support bolts for supporting the gas riser. The support bolts pass through the support bolt holes and are fixed to the cross brace by nuts. The support has expansion bolt holes and expansion bolts for fixing the support to the building wall.

[0007] The support and cross brace are arranged vertically, and the diagonal brace is at a 45-degree angle to the cross brace.

[0008] The supports and diagonal braces are made of galvanized flat steel, and the cross braces are made of U-shaped steel. The support bolt holes are located on the bottom surface of the U-shaped steel.

[0009] The aforementioned urban gas riser bracket is used for gas risers with a diameter of DN80 or less that are between 12 and 20 stories. The gas riser is fixed by adjusting nuts and bolts to form a fixing component, and the assembly is subjected to the vertical load of the gas riser.

[0010] The urban gas riser bracket converts the vertical load on the fixing components and the bracket body into the lateral pull-out bearing capacity of the expansion bolts through the expansion bolts, thereby achieving riser support through force conversion.

[0011] The innovation of this utility model lies in its novel fixing structure at the fastener location. Adjustable bolts are used to achieve the required pipe fixing, allowing for drilling deviations during bracket drilling. Installation is quick and efficient, requiring only simple assembly of the bracket body and the fastener, significantly improving installation efficiency. This also enhances the adaptability of the bracket. In addition to fulfilling its functional requirements, it facilitates purging and maintenance, providing convenience for construction and maintenance while reducing maintenance costs. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] Figure 2 for Figure 1 AA view. Detailed Implementation

[0014] See Figure 1 and Figure 2 This utility model of a riser support mainly consists of a support body, connecting parts, and fixing parts. The fixing parts include support bolts 5 and nuts 6; the support body includes a zinc-plated flat steel support 1, a galvanized flat steel diagonal brace 3, and a U-shaped steel cross brace 4; the connecting parts include expansion bolts 2. The main function of the riser support is to provide fixed support for the gas riser 7. The fixing parts are subjected to the vertical force of the riser, which is converted into the pull-out bearing capacity of the connecting parts through the support body to achieve the fixing function.

[0015] The galvanized flat steel support 1, U-shaped steel cross brace 4, and galvanized flat steel diagonal brace 3 are connected to form a triangular bracket body. The bottom surface of the U-shaped steel cross brace 4 is provided with support bolt holes. The U-shaped steel cross brace 4 is provided with support bolts 5 for supporting the gas riser. The head of the support bolt 5 is on top and the screw passes through the support bolt hole from top to bottom and is fixed to the U-shaped steel cross brace 4 by nuts 6 set at the upper and lower ends of the support bolt hole. The galvanized flat steel support 3 is provided with expansion bolt holes. The expansion bolts 2 pass through the expansion bolt holes to fix the galvanized flat steel support 1 to the wall surface where the gas riser is located.

[0016] The riser support is assembled by vertically welding a U-shaped steel cross brace 4 to a galvanized flat steel support 1. Then, a galvanized flat steel diagonal brace 3 is used to fix the welded joint between the U-shaped steel cross brace 4 and the galvanized flat steel support 1. The welding angle of the galvanized flat steel diagonal brace 3 is 45°, forming a stable triangular structure with the galvanized flat steel support 1, U-shaped steel cross brace 4, and galvanized flat steel diagonal brace 3. Next, support bolts 5 are fixed to the slots of the U-shaped steel cross brace 4 using nuts 6, and then the entire assembly is fixed to the wall using expansion bolts 2. The galvanized flat steel support 1 is parallel to and against the wall surface, while the U-shaped steel cross brace 4 is perpendicular to the wall surface. The nuts of the support bolts 5 press against the riser plug cap 8 at the bottom of the gas riser, ensuring sufficient strength and stability under vertical load. Adjusting nuts work in conjunction with support bolts to allow for quick assembly and disassembly of the riser, facilitating later maintenance and repair.

[0017] The new structure of the gas riser bracket is characterized by the fastener support bolt 5 and nut 6. During the construction and installation of the riser, the drilling accuracy requirement of the expansion bolt 2 of the connector is reduced. If the drilling position is too low, the riser can be fixed by adjusting the relative position of the nut 6 and the support bolt 5. In the later operation and maintenance of the riser, the riser end plug can be disassembled and repaired by adjusting the fastener.
