Description

Technical Field

[0001] This utility model relates to the field of fire protection engineering technology, and in particular to a fire pipe connection bracket for fire protection engineering. Background Technology

[0002] Fire protection piping refers to pipe materials used in fire protection to connect fire protection equipment and materials, and to transport fire-fighting water, gas, or other media. Due to special requirements, fire protection piping has specific requirements for thickness and material, and is painted red. Fire protection piping supports are devices used to fix and connect fire protection piping. They are usually made of metal and have high strength and stability. Their function is to ensure that fire protection piping does not loosen or shift due to vibration, pressure, or other factors during use. Fire protection piping supports can be customized according to the layout and installation requirements of the piping, and are available in different shapes and specifications.

[0003] Commonly used connections for fire-fighting pipes often involve directly nesting two semi-circular clamps around the connection point and securing them with bolts. However, the clamping surface is singular and narrow, resulting in weak limiting and a lack of opposing tightening force. This makes the pipes prone to thermal expansion and contraction due to changes in ambient temperature. Consequently, the corresponding connection points will deform under thermal expansion and form gaps under thermal contraction. Conventional connection brackets cannot restore the resulting deformation and gaps, easily leading to loosening and leakage, which affects fire safety. Utility Model Content

[0004] The purpose of this utility model is to provide a fire pipe connection bracket for fire protection engineering, which can increase the clamping surface, improve the limiting strength of the pipe, and freely adjust to the expansion and contraction of the pipe under changes in ambient temperature, so as to avoid the problem of compression deformation and gaps at the pipe connection, improve the sealing performance of the pipe connection, and reduce fire hazards.

[0005] To achieve the above objectives, a fire pipeline connection bracket for fire protection engineering is provided, comprising: a mounting plate, on which guide rails are symmetrically fixed at the bottom left and right, and brackets are symmetrically slidably fitted on the inner sides of the guide rails; symmetrically mounted sleeves are provided directly below the mounting plate, and the bottom ends of the brackets on opposite sides are fixedly connected to the sleeves; clamps are assembled at the bottom of each sleeve; bolts are fitted at both ends of the sleeves and clamps to lock them to the outer wall of the fire pipeline; a clamping plate is fixedly connected to the center of the top side of each sleeve; a T-shaped slide rail is slidably fitted on the center of the top side of the clamping plate; the top side of the T-shaped slide rail is fixedly connected to the mounting plate; and the center of the opposite side of the clamping plate is... A sliding shaft is installed at the rear, with threaded sleeves on both the front and rear outer sides of the shaft. A tension spring is slidably fitted onto the outer side of the shaft, and both ends of the tension spring are fixedly connected to a clamping plate. By using double-sleeve clamps, clamps, and bolts, the connecting ends of adjacent fire-fighting pipes are individually nested and fixed, increasing the clamping surface and improving the limiting strength of the pipes. Simultaneously, the clamping plate, sliding shaft, and tension spring ensure that there is always a tensile force along the pipe axis between the pipes, ensuring a tight fit at the pipe connection. This allows for free adjustment with the expansion and contraction of the pipes under changing ambient temperatures, preventing compression deformation and gaps, improving the sealing performance of the pipe connection, and reducing fire hazards.

[0006] According to the aforementioned fire-fighting pipeline connection bracket for fire protection engineering, a rubber pad is attached to one side of the threaded sleeve, and the opposite side of the rubber pad is pressed and attached to the clamping plate. This provides a certain elastic buffer for the clamping plate's adaptive external support during pipeline thermal expansion.

[0007] According to the aforementioned fire pipe connection bracket for fire protection engineering, the top of the mounting plate has a rectangular array of mounting holes, and screws are fitted into these holes to secure the mounting plate to the placement surface. This ensures that the mounting plate is fully fixed to the placement surface.

[0008] According to the fire pipe connection bracket for fire protection engineering, the inner surfaces of both the sleeve and the clamp are fitted with a layer of anti-slip rubber to increase the anti-slip performance after nesting.

[0009] According to the fire pipe connection bracket for fire protection engineering, each of the sleeves has symmetrically fixed bracket bars on its top. The outer sides of the top of each bracket bar have sliding limit grooves that engage with the sleeve. The top of each limit groove is fixedly connected to the mounting plate. This assists in limiting the sleeve and improving the overall connection strength.

[0010] According to the fire protection pipe connection bracket for fire protection engineering, the outer edges of both the sleeve and the clamp are rounded to prevent the edges of the sleeve or clamp from tilting and causing indentations on the outer wall of the pipe.

[0011] According to the aforementioned fire pipe connection bracket for fire protection engineering, the top of both the bracket and the support bar has a T-shaped structure and is correspondingly embedded in the inner side of the guide rail and the limiting slide groove, thus providing limiting and sliding connection in the front-to-back direction. While maintaining sliding, it also provides limiting support, adapting to different installation positions.

[0012] According to the fire protection pipe connection bracket for fire protection engineering, the mounting plate has symmetrically arranged hanging holes on the top side center. These holes are used to attach the bracket to the ceiling via inserted hanging rods.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] In this invention, double-sleeve clamps, along with clamps and bolts, are used to individually nest and fix the connecting ends of adjacent fire-fighting pipes, increasing the clamping surface and improving the limiting strength of the pipes. Simultaneously, a clamping plate, along with a sliding shaft and a tension spring, ensures a constant axial tension between the pipes, guaranteeing a tight fit at the pipe connection. This allows for free adjustment as the pipes expand and contract with changes in ambient temperature, preventing deformation and gaps, improving the sealing of the pipe connection, and reducing fire hazards.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
