Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of basement pipeline design, and particularly relates to a hidden type ventilation pipeline structure of a spraying type. BACKGROUND

[0002] At the present stage, the national standard requires that when the width of the ventilation pipeline is greater than 1.2 m, a spraying head should be additionally arranged below the ventilation pipeline.

[0003] The spraying pipeline affects the height of the basement and is not beautiful. The ventilation pipeline and the spraying pipeline each need to be fixed by a support hanger, and the pipeline installation efficiency is low.

[0004] In addition, because the basement has a height limitation, the spraying pipeline suspended below the ventilation pipeline can compress the height space.

[0005] At present, the spraying ventilation pipeline still has some problems, for example:

[0006] Aesthetic defect: the spraying pipeline exposed below the air pipe can destroy the continuity of the suspended ceiling, and especially in places (such as exhibition halls and hotel lobbies) where space aesthetics is emphasized, visual abruptness is easily formed.

[0007] Design coordination difficulty: when the spraying construction drawing is designed, it is difficult to coordinate various professions, and it is often necessary to explain how to lay the spraying head when meeting the air pipe by a legend, and on-site construction adjustment is still needed, which greatly increases the labor cost; if the installation is missing, there is a safety hazard, and the fire safety inspection cannot be passed.

[0008] Height compression problem: the spraying installation needs to reserve an operation height (usually greater than or equal to 10 cm), which can cause the overall downward movement of the suspended ceiling, and causes obvious space compression in places (such as loft apartments and underground garages) with a height of less than or equal to 3 meters; some building standards need to meet the minimum net height standard (such as the "Uniform Standard for Civil Building Design"), and the addition of the spraying head can force the height adjustment, and increase the structure modification cost.

[0009] High construction complexity: the spraying installation needs to avoid the air pipe support hanger, and the branch pipe below the air pipe cannot be fixed. The spraying needs to be installed after the air pipe is completely installed and the strength and tightness test is passed, the construction period is prolonged, and one more process increases the management cost. UTILITY MODEL CONTENTS

[0010] The utility model aims to provide a hidden type ventilation pipeline structure of a spraying type, which has high appearance integrity, protects the spraying pipeline, and can save the height.

[0011] The utility model provides a hidden type ventilation pipeline structure of spraying, which comprises a ventilation pipe and a spraying pipeline.

[0012] In the utility model, the recess of the ventilation pipe is provided with heat preservation and insulation cotton, and the spraying pipeline can be attached to the heat preservation and insulation cotton to provide heat insulation for the spraying pipeline and prolong the service life of the spraying pipeline.

[0013] In the utility model, the ventilation pipe is further covered with a fireproof plate layer, which covers the recess and the spraying pipeline and provides fireproof and high-temperature resistant functions.

[0014] In the utility model, the ventilation pipe is formed by surrounding a metal plate, and the recess is formed by stamping the ventilation pipe as a whole.

[0015] In the utility model, the recess of the ventilation pipe is provided with a pipeline buckle, and the spraying pipeline is connected through the preset buckle to further stabilize the spraying pipeline in a suspended state.

[0016] During installation, the ventilation pipe adopts a conventional modular standard size, the ventilation pipe is erected in the basement, and the spraying pipeline is arranged near the ventilation pipe. For some spraying heads designed below the ventilation pipe, the branch spraying pipeline can be extended to the recess position of the side surface of the ventilation pipe, and then arranged in the recess and bent into the recess of the bottom plate along the recess of the side plate of the ventilation pipe, and then the spraying pipeline port is provided with a spraying head. The heat preservation and insulation cotton and the fireproof plate layer provide fireproof and heat insulation protection for the ventilation pipe and the spraying pipeline, and improve the service life.

[0017] The utility model has the advantages that: first, from the appearance, no numerous spraying pipelines appear below the pipeline and appear disorderly; and the originally suspended spraying pipeline does not need to be suspended and is directly fixed through the modular preset pipeline buckle attached to the inner wall of the recess of the ventilation pipe and the preset heat preservation and insulation cotton, without additional coating operation, which greatly speeds up the construction speed; second, because the spraying pipeline is hidden and embedded, it does not additionally occupy the space below the ventilation pipeline, does not increase the height limit, and provides more possibilities for some facility design; third, because the spraying pipeline is designed to be embedded, the suspended spraying pipeline will not be hit during some high-altitude reconstruction and maintenance of the basement in the future.

[0018] The utility model has the advantages of simple structure, improved construction efficiency, safety and reliability. DRAWINGS
