Description

TECHNICAL FIELD

[0001] The utility model relates to engineering welding field especially a kind of adjustable fire connecting device in narrow space. BACKGROUND

[0002] In the construction welding process, the high temperature of welding slag is a problem that cannot be ignored, and the unregulated falling of welding slag during welding is an important factor causing construction engineering fire.

[0003] With the continuous development of construction technology, some new materials may be restricted by traditional construction methods. The original old materials have fire protection function, but after using new materials, there are outstanding effects in some aspects, but the fire protection performance is decreased. For example, the original coiled material has a concrete fire protection layer, and welding on it will not burn through the coiled material, but using the emerging pre-laid anti-sticking waterproof material loses the fire protection layer, and welding operation on it is easy to burn through the coiled material and cause water leakage.

[0004] Therefore, the promotion and use of emerging materials will inevitably be accompanied by the update and iteration of fire protection layers, and the existing welding fire protection measures and their problems include:

[0005] 1. Steel bar hook is made to spread fireproof cloth or rock wool and other fireproof materials in steel reinforcement framework. This method is difficult to operate, has poor applicability, poor protection effect and poor turnover.

[0006] 2. A foldable umbrella-shaped fire connecting pot is processed, which has great difficulty in processing technology, is greatly affected by internal space when opening and closing, and has poor applicability.

[0007] 3. Rock wool is placed at the falling fire point and water is sprayed. This method is not economical when there are many welding points, is not environmentally friendly, is difficult to drain water subsequently, increases humidity in the operation area due to watering, and affects the welding quality.

[0008] In particular, in the welding operation at the dense part of the steel reinforcement framework, the lower part adopts new pre-laid anti-sticking high polymer waterproof coiled material or prestressed reserved pipeline and other key protection parts, and the conventional fire connecting device cannot enter the steel reinforcement framework, which undoubtedly puts forward higher requirements for the protection of such welding operation products.
