Description

Compound fire prevention tuber pipe of discharging fume

Technical Field

The utility model relates to a tuber pipe technical field of discharging fume, more specifically relates to a compound fire prevention tuber pipe of discharging fume.

Background

The fire-fighting smoke prevention and exhaust system is widely applied to places needing smoke prevention and exhaust, such as office buildings, hotels, restaurants, movie theaters, markets, hospitals, underground parking lots and the like. At present, air pipes used for preventing and discharging smoke are mostly made of steel plates or galvanized steel plates, and the equipment is not subjected to fireproof protection treatment, so that the equipment does not have a fireproof function. Therefore, in the prior art, a layer of fireproof plate is combined and connected with the prior air pipe technology to play a certain fireproof role.

Because building inner structure is complicated, and it is also more complicated to discharge fume the tuber pipe route, consequently the tuber pipe of discharging fume all assembles one section when the equipment, directly adopts a connection frame fixed at two rows of cigarette tuber pipe junctions at present, and the equipment difficulty is great, and fixed knot constructs not firm stable, and it is easy not hard up when receiving great vibrations to make junction gap grow, the problem can be revealed in the in-process of discharging fume.

Therefore, it is a realistic meaning for those skilled in the art how to solve the above technical problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: in order to solve the present tuber pipe equipment degree of difficulty of discharging fume great, the structure is firm stable inadequately, and is not hard up easily when receiving great vibrations to make junction gap grow, the technical problem who reveals easily among the smoke exhaust process, the utility model provides a compound fire prevention tuber pipe of discharging fume.

The utility model discloses a realize above-mentioned purpose and specifically adopt following technical scheme:

the utility model provides a compound fire prevention tuber pipe of discharging fume, includes two rectangle tuber pipes, and two rectangle tuber pipe outer wall four sides all are provided with the channel-section steel that is located two rectangle tuber pipe junctions, and two rectangle tuber pipes all seted up with channel-section steel complex draw-in groove, but in the draw-in groove was gone into to the card of the two straight sides of channel-section steel.

Furthermore, a plurality of fastening screws are arranged between the two rectangular air pipes and the channel steel.

Furthermore, the rectangular air pipe comprises a stainless steel air pipe, a fireproof pipe and a rock wool pipe which are sequentially connected from inside to outside.

Furthermore, the thickness of the stainless steel air pipe is 0.5-1mm, the thickness of the fireproof pipe is 2-5mm, and the thickness of the rock wool pipe is 10-30 mm.

The utility model has the advantages as follows:

1. when assembling two rectangle tuber pipes, all adopt a channel-section steel card to advance in the draw-in groove of rectangle tuber pipe on the four sides, can be in the same place two rectangle tuber pipes amalgamations, and the operation degree of difficulty is lower, is adopting the screw to fix the channel-section steel at two rectangle tuber pipe outer walls after assembling, and the firm stability of structure is difficult not hard up.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

In the description of the present application, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present application and simplifying the description, but do not indicate or imply that the referred device or element must have a particular orientation, be constructed in a particular orientation, and be operated, and thus should not be construed as limiting the present application.

The features and properties of the present invention are described in further detail below with reference to examples.

Example 1

As shown in fig. 1 to 4, this embodiment provides a compound fire prevention tuber pipe of discharging fume, including two

rectangle tuber pipes

1, 1 outer wall four sides of two rectangle tuber pipes all are provided with the channel-section steel 2 that is located 1 junction of two rectangle tuber pipes, two rectangle tuber pipes 1 all seted up with channel-section steel 2 complex draw-in grooves, but 2 two straight flanges of channel-section steel block into in the draw-in groove.

During the equipment, will be in the same place two rectangle tuber pipes 1 amalgamation earlier, then adopt two straight sides of channel-section steel 2 to block respectively into two rectangle tuber pipes 1's draw-in groove, two rectangle tuber pipes 1 four lateral walls all assemble through channel-section steel 2, can be in the same place two rectangle tuber pipes 1 amalgamations, and the operation degree of difficulty is lower, because in channel-section steel 2 directly injects rectangle tuber pipe 1, the firm stability of structure is difficult not hard up.

As an optimal technical solution of the utility model:

be provided with a plurality of fastening screw 3 between two rectangle tuber pipes 1 and the channel-section steel 2, two rectangle tuber pipes 1 are through the good back of channel-section steel 2 equipment, and a plurality of fastening screw 3 of rethread are fixed, and here fastening screw 3 need pass two rectangle tuber pipes 1 respectively.
