Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation modules, and particularly relates to a finished floor ventilation opening module. Background Technique

[0002] In the design of pipe galleries, the ventilation openings above the ground account for a relatively large part of the pipe galleries. The existing ventilation openings above the ground of pipe galleries need to be completed by casting a convex ventilation structure on the reserved ventilation opening position. Its structure is that air outlets are arranged on the surrounding side walls of the convex part, and then a flat plate is covered on the top.

[0003] The ground ventilation system adopts a design method in which the inlet grille is smaller than the diameter of the air supply duct, which can increase the gas suction rate. Since the ventilation grille is smaller than the vertical air duct, when the ground concrete is poured, the concrete will enter the air duct, thus affecting the subsequent ventilation effect of the air duct. Therefore, we propose a finished floor ventilation opening module to solve the above-mentioned problems. Content of the Utility Model

The ventilation part 411 is installed in the vertical air duct, and the anti-entry part 412 and the connection part 413 are respectively installed at two ends of the ventilation part 411. The expansion bolt 42 connects the connection part 413 and the enclosed concrete 1. A threaded hole is opened on the anti-entry part 412. The screw rod 44 is installed at the lower end of the reinforcing member 43, and the screw rod 44 is threadedly arranged in the threaded hole.

[0029] Specifically, when installing the air duct, to prevent concrete from entering the interior of the air duct during the subsequent pouring of the building floor 3, which would affect the ventilation effect, an air duct assembly 4 can be provided inside the vertical air duct. The main body 41 is stably connected to the encapsulated concrete 1 through expansion bolts 42. Since the main body 41 includes a ventilation part 411, an anti-entry part 412, and a connection part 413, the connection part 413 is stably connected to the encapsulated concrete 1 through expansion bolts 42. And because the height of the anti-entry part 412 is higher than the height of the building floor 3, the anti-entry part 412 can effectively prevent concrete from entering the ventilation part 411, thereby avoiding concrete from entering the air duct interior.

[0030] Furthermore, to further enhance the protection effect, threaded holes can be opened on the anti-entry part 412. The reinforcing member 43 and the lead screw 44 are connected, and the lead screw 44 is threadedly arranged in the threaded holes. The overall height of the anti-entry part 412 can be further increased through the reinforcing member 43, thereby preventing concrete from entering the air duct interior.

[0031] In this embodiment, the ventilation part 411 is arranged as a rectangular tubular structure, and the interior of the ventilation part 411 is hollow. The height of the anti-entry part 412 is greater than the height of the building floor 3.

[0032] Specifically, during actual use, the size and shape of the ventilation part 411 can be adjusted according to the shape and size of different air ducts. In this embodiment, the lead screw 44 is arranged as a rectangular structure and is hollow inside.

[0033] In this embodiment, the ventilation part 411 is arranged as a circular tubular structure, and the interior of the ventilation part 411 is hollow.

[0034] Specifically, during actual use, the size and shape of the ventilation part 411 can be adjusted according to the shape and size of different air ducts. In this embodiment, the lead screw 44 is arranged as a circular structure and is hollow inside.

[0035] In this embodiment, the grille assembly 5 includes a grille 53, A clamping teeth 54, B clamping teeth 55, and B springs 56. Connection grooves are opened on the anti-entry part 412. A plurality of B springs 56 are provided, and all the plurality of B springs 56 are installed in the connection grooves. The B clamping teeth 55 are installed at the ends of the plurality of B springs 56. The A clamping teeth 54 are installed on the grille 53. The grille 53 is arranged above the ventilation part 411, and the A clamping teeth 54 and the B clamping teeth 55 are clamped.

[0036] Specifically, when installing the grille 53, a connecting groove can be first opened on the anti-entry portion 412, and a plurality of B springs 56 are set in the connecting groove, and the B engaging teeth 55 are installed on the ends of the plurality of B springs 56, so that the B engaging teeth 55 can slide in the connecting groove. At this time, the A engaging teeth 54 are connected to the grille 53, and the A engaging teeth 54 are slowly inserted into the connecting groove. Through the engagement of the A engaging teeth 54 and the B engaging teeth 55, the grille 53 can be stably set.

[0037] In this embodiment, the grille assembly 5 also includes a blocking piece 51 and an A spring 52. An installation groove is opened on the anti-entry portion 412. The A spring 52 is installed in the installation groove. The blocking piece 51 is installed at the end of the A spring 52. The blocking piece 51 is arranged at the notch of the connecting groove.

[0038] Specifically, in actual use, in order to prevent the A-engaging tooth 54 from falling off due to external factors, thereby causing the A-engaging tooth 54 to no longer be engaged with the B-engaging tooth 55, thereby causing the grille 53 to fall off, an installation groove can be opened at the end of the anti-entry portion 412, and an A spring 52 can be arranged in the installation groove to connect the blocking member 51 to the end of the A spring 52. At this time, the A spring 52 can be used to push the blocking member 51 to move, and then the blocking member 51 can be used to close the notch of the connecting groove, thereby preventing the A-engaging tooth 54 from detaching from the connecting groove.

[0039] In this embodiment, the A engaging teeth 54 and the B engaging teeth 55 are of the same size and shape.

[0040] Specifically, in order to enable the A engaging tooth 54 and the B engaging tooth 55 to engage with each other, the sizes and shapes of the two are set to be the same, and the engaging teeth of the two are both provided with arc structures and right-angle structures, so that the two can be engaged with each other.
