Fireproof structure allowing pipeline to penetrate lightgage steel joist gypsum board partition wall and construction method of fireproof structure

Abstract

The invention relates to a fireproof structure allowing a pipeline to penetrate a lightgage steel joist gypsum board partition wall and a construction method. The fireproof structure comprises a penetrating hole, rock wool, an added board and fire-resisting sealant, wherein the penetrating hole is formed in the lightgage steel joist gypsum board partition wall and allows the pipeline to penetrate; the position between the outer wall of the pipeline and the penetrating hole is filled with the rock wool; the added board blocks an opening of the penetrating hole and is arranged above the pipeline and fixedly connected with the lightgage steel joist gypsum board partition wall; and the position between the added board and the pipeline is filled with the fire-resisting sealant. The penetrating hole is filled with the rock wool, and the opening is sealed through the added board and blocked through the fire-resisting sealant; gypsum boards are adopted in the added board, so that the fireproof performance of opening blockage can be wholly improved, and the refractory time limit requirement is met; and the opening is densely blocked by the added board, so that the structure is firm. On the basis of meeting the refractory time limit requirement, a large amount of fire-resisting sealant is saved, the problem of non-plasticity of the opening of lightgage steel joist gypsum board partition wall is solved, and the refractory time limit is effectively prolonged.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a fireproof structure in which pipes pass through a light steel keel gypsum board partition wall and a construction method thereof. Background technique [0002] Light steel keel gypsum board partition walls are used more and more in modern buildings. The structure of the light steel keel gypsum board partition wall includes a light steel keel in the middle and gypsum boards on both sides of the light steel keel. The gypsum board has Good fire resistance, generally multi-layer boards, the number of layers of gypsum boards should be selected according to the requirements of the fire resistance time limit. In building construction, the pipeline needs to pass through the light steel keel gypsum board partition wall. In order to facilitate construction, the reserved hole or rear opening on the light steel keel gypsum board partition wall is designed to be larger than the outer di...
