Description

Technical Field

[0001] This invention relates to the field of building decoration technology, specifically to a structure for fixing the ceiling and electromechanical pipelines under the grandstand. Background Technology

[0002] For the stands of large stadiums, ventilation is typically achieved through under-seat air supply. Specifically, a large plenum chamber is usually installed beneath the stands as the air supply system. Most of the space beneath the stands is usually used as functional rooms for meetings and offices. These functional rooms require secondary renovations. Traditionally, the ceiling hangers need to pass through the plenum chamber before being fixed to the concrete floor slab of the stands. The electromechanical wiring inside the ceiling needs to be supported by brackets, which also need to pass through the plenum chamber before being fixed to the concrete floor slab. Since the plenum chamber is composed of multiple insulation panels, holes need to be made in the insulation panels where the hangers and the brackets supporting the electromechanical wiring pass through. This construction method easily leads to air leaks at these openings. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the construction method of making holes in the insulation board at the location where the suspension rods of the fixed ceiling and the brackets supporting the electromechanical pipelines pass through the static pressure box in the stands of large stadiums can easily cause air leakage at the opening.

[0012] Optionally, the boom assembly further includes:

[0013] A washer is fitted onto the main body of the hanger rod, and the washer is located between the nut and the bottom surface of the square tube keel; the edge of the washer extends beyond the edge of the nut.

[0037] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] The current construction method, which uses hangers and supports to pass through the plenum chamber, is not only slow but also requires subsequent repairs to the insulation boards. Furthermore, due to the low temperature of the air conditioning air, condensation easily forms at the contact points between the hangers and the insulation boards. This condensation, flowing down the hangers onto the ceiling, can damage it. For these reasons, this application proposes a structure for fixing the ceiling and electromechanical pipelines under the grandstand.

[0042] like Figures 1 to 7 One specific embodiment of the structure for the fixed ceiling and electromechanical pipelines under the grandstand shown includes: a suspension rod assembly 3 and a support assembly. Specifically, the grandstand is a tiered grandstand 1 in a sports stadium. The tiered grandstand 1 in the sports stadium can be a tiered grandstand in a swimming pool.

[0043] like Figure 1 and Figure 2 As shown, the hanger assembly 3 is arranged vertically; the bottom end of the hanger assembly 3 is connected to the ceiling 2, and the top end of the hanger assembly 3 is connected to the square tube keel 6; the square tube keel 6 is located below the insulation board 5. (Combined with...) Figures 3 to 5As shown, angle steel 7 is fixed on both sides along the length of the square tube keel 6; the angle steel 7 is suitable for supporting the insulation board 5; the insulation board 5 is suitable for splicing the static pressure box. The upper end of the support component is connected to two spaced first square tubes 4, and the lower end of the support component is suitable for supporting the electromechanical pipeline 14; the square tube keel 6 is connected to the concrete floor slab 15 of the grandstand through the first square tubes 4.

The nut 11 is threaded onto the hanger body 8 near the top end. Without the washer 12, the hanger assembly 3 has a first state in which the top support 9 passes through the strip hole 13 on the bottom surface of the square tube keel 6; a second state in which the hanger body 8 is rotated so that the edge of the top support 9 overlaps with the inner bottom wall of the square tube keel 6; and a third state in which the nut 11 is screwed on until it abuts against the bottom surface of the square tube keel 6, and the edge of the top support 9 abuts against the inner bottom wall of the square tube keel 6.

[0046] After the washer 12 is installed, it is fitted onto the rod body 8, and the washer 12 is located between the nut 11 and the bottom surface of the square tube keel 6. The edge of the washer 12 extends beyond the edge of the nut 11, and in the third state, the washer 12 abuts against the bottom surface of the square tube keel 6. Specifically, the length of the strip hole 13 is 500mm, the width of the strip hole 13 is 10mm, and it is a rectangular square hole; the interval between adjacent strip holes 13 is 500mm. The top support 9 is a semi-circular plate. The square tube keel 6 is hot-dip galvanized. The square tube keel 6 can be 100mm high, 50mm wide, and 7mm thick.

[0047] Furthermore, a protrusion 10 is provided on the rod body 8 near the lower part of the nut 11. The protrusion 10 is adapted to have its protrusion direction parallel to the length direction of the strip hole 13 in the first state, and the protrusion 10 is adapted to have its protrusion direction perpendicular to the length direction of the strip hole 13 in the second and third states. Specifically, the protrusion 10 is a triangular protrusion.

[0048] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the support assembly includes two second square tubes 16 and C-shaped steel 17. Both second square tubes 16 are arranged vertically; the top ends of the two second square tubes 16 are detachably connected to the bottom ends of two spaced first square tubes 4; support members 18 are fixedly provided at the bottom ends of the second square tubes 16. The C-shaped steel 17 is arranged horizontally, and its two ends overlap the support members 18 of the corresponding two second square tubes 16; the ends of the C-shaped steel 17 are detachably connected to the second square tubes 16; the electromechanical pipeline 14 is placed on multiple C-shaped steels 17 arranged in the same manner. Specifically, the top end of the second square tube 16 passes through the interior of the first square tube 4, and the second square tube 16 is connected to the first square tube 4 by a first bolt 19; the C-shaped steel 17 is connected to the second square tube 16 by a second bolt 20. The second square tube may be 35mm high, 35mm wide, and 3mm thick. The second square tube is hot-dip galvanized. The first square tube can be 50mm high, 50mm wide, and 5mm thick.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
