Description

Technical Field

[0001] The utility model relates to the technical field of modular houses, in particular to a support and hanger fixing structure of a fire sprinkler pipe in a modular house. Background Art

[0002] Modular houses have gradually begun to come into people's view, but most people are still not very clear about the concept of modular houses. The so-called modular houses are to divide the components of the house into different functional modules, and use standardized, modular and universal production to realize factory manufacturing. The house can be assembled on site anytime and anywhere, and the whole process only takes a few hours to complete.

[0003] Currently, there are two types of fire sprinkler pipes in modular buildings:

[0004] a. Using a combination of umbrella-shaped nails and screws to hold the ceiling panels in place is a simple and quick method. However, sprinkler pipes are generally made of galvanized steel pipes, which are heavy and insufficient for the ceiling's load-bearing capacity. Furthermore, welding steel plates above the ceiling for reinforcement also presents another problem: the umbrella-shaped nails need to be drilled through the ceiling to extend above the ceiling. Due to the special nature of modular buildings, these nails may become loose and shaky during transportation.

[0005] b. Pre-welding screws on the top beam of the box to serve as sprinkler pipe supports and hangers has significant drawbacks. First, pre-welding can inevitably lead to box deformation and construction errors, causing the fixing points to shift, and even affecting pipe installation. Second, if the screws are too long, it will affect the sealing of the ceiling panels. Utility Model Content

[0006] The purpose of the present invention is to solve the problem in the above background technology that the fire sprinkler pipes are easy to loosen and affect the packaging of the ceiling panels, and to propose a support and hanger fixing structure for the fire sprinkler pipes in a modular house.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] The support and hanger fixing structure of the fire sprinkler pipe in the modular house includes multiple top beams and steel plate bending parts. The bottom of the top beam is fixedly connected to the fireproof ceiling. The steel plate bending parts are fixedly welded between two adjacent top beams. The bottom of the fireproof ceiling is provided with C-shaped steel. The C-shaped steel is connected to the steel plate bending parts through multiple self-tapping screws. The bottom of the C-shaped steel is connected to a snap assembly through multiple screws. The screws are threaded with fastening nuts and spring nuts.

[0009] Preferably, the bottom of the steel plate bending part is arranged horizontally with the bottom of the top beam.

[0010] Preferably, the fireproof ceiling is made of waterproof gypsum board.

[0011] Preferably, the buckle assembly is a pipe saddle-shaped buckle, and a flat washer is inserted between the pipe saddle-shaped buckle and the fastening nut.

[0012] Preferably, the buckle assembly is a pipe elevator, and a washer gasket is inserted between the pipe elevator and the C-shaped steel.

[0013] Preferably, the self-tapping screw is an external hexagonal dovetail self-tapping screw.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present invention, a steel plate is pre-embedded and welded at the top of the support bracket range, and self-drilling nails are used to penetrate the C-shaped steel, ceiling and top pre-embedded steel plate at the bottom of the ceiling. This method greatly improves the strength, and the bracket can be arbitrarily adjusted in the C-shaped steel track. The positioning size is effectively solved. Various problems in the previous practice such as inaccurate positioning, insufficient strength and influence on the next process.

[0016] 2. The fixed structure of this utility model allows for installation of pipe supports and hangers at any location after the ceiling is completed, offering greater flexibility and minimizing impact on both previous and subsequent processes. Regarding the supports and hangers themselves, this method is more secure and flexible, and can accommodate installation of various pipe supports and hangers in addition to fire sprinkler pipes by adjusting the various fasteners.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1:

[0022] Reference Figure 1The support and hanger fixing structure of the fire sprinkler pipe in the modular house includes multiple top beams 1 and steel plate bending parts 2. The bottom of the steel plate bending part 2 is arranged horizontally with the bottom of the top beam 1. The bottom of the top beam 1 is fixedly connected to the fireproof ceiling 3, and the fireproof ceiling 3 is made of waterproof gypsum board.

[0023] In this embodiment, the steel plate bending part 2 is fixedly welded between two adjacent top beams 1, and a C-shaped steel 4 is provided at the bottom of the fireproof ceiling 3. The C-shaped steel 4 is connected to the steel plate bending part 2 by a plurality of self-tapping screws 5. The self-tapping screws 5 are external hexagonal dovetail self-tapping screws.

[0024] In this embodiment, the bottom of the C-shaped steel 4 is connected to a snap assembly through multiple screws 6. The snap assembly is a pipe saddle-shaped snap 8. A flat washer 9 is inserted between the pipe saddle-shaped snap 8 and the fastening nut 7. The fastening nut 7 and the spring nut 12 are threadedly sleeved on the screw 6.

[0025] In this embodiment, by pre-embedding and welding steel plates at the top of the support bracket range in advance, self-drilling and self-tapping nails are used to penetrate the C-shaped steel, ceiling and top pre-embedded steel plates at the bottom of the ceiling. This method greatly improves the strength, and the bracket can adjust the positioning size arbitrarily within the C-shaped steel track; it effectively solves the various problems of inaccurate positioning, insufficient strength and impact on the next process in previous practices.

[0026] Example 2:

[0027] Reference Figure 2 The support and hanger fixing structure of the fire sprinkler pipe in the modular house includes multiple top beams 1 and steel plate bending parts 2. The bottom of the steel plate bending part 2 is arranged horizontally with the bottom of the top beam 1. The bottom of the top beam 1 is fixedly connected to the fireproof ceiling 3, and the fireproof ceiling 3 is made of waterproof gypsum board.

[0028] In this embodiment, the steel plate bending part 2 is fixedly welded between two adjacent top beams 1, and a C-shaped steel 4 is provided at the bottom of the fireproof ceiling 3. The C-shaped steel 4 is connected to the steel plate bending part 2 by a plurality of self-tapping screws 5. The self-tapping screws 5 are external hexagonal dovetail self-tapping screws.

[0029] In this embodiment, the bottom of the C-shaped steel 4 is connected to a snap assembly through multiple screws 6. The snap assembly is a pipe hanger 10. A washer gasket 11 is inserted between the pipe hanger 10 and the C-shaped steel 4. A fastening nut 7 and a spring nut 12 are threadedly sleeved on the screw 6.

[0030] In this embodiment, the specific construction steps include:

[0031] Step 1: After the ceiling construction is completed, cut the finished C-shaped steel 4 to the appropriate size according to the design drawings, position it according to the drawings, and use the hexagonal dovetail self-tapping screws 5 to pass the C-shaped steel 4 through the ceiling and the steel plate bending parts to fix it firmly.

[0032] Step 2: According to the support and hanger form, confirm the required number of spring nuts 12. For example, the pipe saddle clip 8 requires two spring nuts 12, while the pipe elevator 10 only requires one spring nut 12. Connect the spring nuts 12, washer 11, pipe saddle clip 8 or pipe elevator 10, flat washer 9, and fastening nut 7 with the screw 6 in the order shown in the drawing and tighten them.

[0033] Step 3: Place the sprinkler pipe 13 in the finished hanger. If the installation space is limited, you can first arrange the pipe and temporarily fix it. After the pipe is installed, tighten the fasteners to complete the installation.
