Abstract

The invention provides a construction method for punching holes in a colored tape of an air suction sampling pipe, and belongs to the field of buildings. The construction method comprises the following steps of: (1) fixing the sampling pipe; (2) measuring and determining the positions of sampling holes in the colored tape; (3) punching the holes by using a special tool; (4) mounting a bracket; (5) determining the positions of the holes; (6) smearing connecting glue; (7) aligning, connecting and fixing according to the colored tape; (8) detecting the perpendicularity of the holes; (9) testing each single loop system; (10) mounting in batches; and (11) testing loops one by one. According to the construction method, the colored tape is smeared on the sampling pipe of an air suction type smoke fire detection and alarm system, the holes are punched in the sampling pipe by using the special tool, the colored tape is connected with the sampling pipe, the sensitivity is tested by using the single loop, and the mounting process of batch mounting and testing is applied, so that the air suction sampling pipe can be quickly connected under the condition that the sampling holes are in a straight line, the system detection precision after the sampling holes are put into operation is guaranteed, meanwhile, the construction efficiency can be improved, and the high-altitude operation time is shortened.

Description

technical field [0001] The invention belongs to the field of intelligent building engineering, and in particular relates to a construction method for opening a color ribbon of a suction sampling tube. Background technique [0002] As the main fire alarm system for tall warehouses, the aspirating fire detection system has been widely used in all kinds of tall warehouse buildings. The technical specification of the aspirating fire detection system requires that the sampling hole on the aspirating detection pipeline is perpendicular to the direction of the movement of the flue gas. It needs to be positioned on a straight line when the sampling hole is processed, and can be unified according to the positioning ribbon during the later installation. Adjust the sampling hole of the entire detection loop vertically downward to ensure the sampling accuracy. In the original construction method, after the hole in the sampling pipeline is opened, it is necessary to hang the line during ...

Problems solved by technology

The technical specification of the aspirating fire detection system requires that the sampling hole on the aspirating detection pipeline is perpendicular to the direction of smoke movement, and it needs to be positioned on a straight line during the processing of the sampling hole, and can be unified according to the positioning color band during later installation. Adjust the sampling hole of the entire detection circuit vertically downward to ensure the sampling accuracy. In the original construction method, after the hole is opened in the sampling pipeline, it is necessary to hang the line during installation or use an infrared instrument to measure and release the control line at high altitude. The operation is relatively convenient, and the time of working at high altitude is long, the safety management is difficult, and the construction efficiency cannot meet the requirements of the construction period. It is necessary to improve the construction technology to ensure the perpendicularity of the sampling hole and the direction of flue gas movement.

[0003] In the past, an auxiliary instrument was needed to calibrate the sampling hole when connecting the aspirating sampling pipe to keep it in a straight line. In the high altitude, the erection and measurement operation of the instrument were limited by the operating platform, and the scaffolding position needed to be moved many times during the operation. To check the installation of the pipeline sampling hole, the safety risk is high
