Embodiment Construction

[0011] See figure 1 , figure 2 As shown, a sealing structure in which a load-bearing beam passes through a flue guard plate, which includes a load-bearing beam 6 and a flue guard plate 1, the load-bearing beam 6 passes through the flue guard plate 1, and the outer side of the load-bearing beam 6 and the flue guard plate 1 are connected. There is a gap between them. A sealing plate 5 is installed on the outer side of the load-bearing beam 6. Corresponding to the outer side of the sealing plate 5, a Y-shaped fork 2 is installed on the flue guard plate 1. The opening of the Y-shaped fork 2 faces the sealing plate 5. The Y-shaped fork Between the opening of 2 and the sealing plate 5, there is an insulation ring 4 which is close to the outer peripheral surface of the sealing plate 5. The insulation ring 4 is surrounded by insulation ropes, and has a simple structure, convenient installation and low cost. The four sealing plates 5 are then formed into a square structure, and four ...

Abstract

The invention relates to the technical field of through-wall sealing of steel structures of flues, in particular to a sealing structure for a load-bearing beam penetrating a flue protection board. The sealing structure can serve a sealing function without affecting relative displacement, can be adapted to temperature variation and has a long service lift. The sealing structure comprises the load-bearing beam, and the flue protection board, wherein the load-bearing beam penetrates the flue protection board. The sealing structure is characterized in that a gap is reserved between the outer side of the load-bearing beam and the flue protection board; sealing boards are mounted on the peripheral surface of the load-bearing beam; Y-shaped forks corresponding to the outer sides of the sealing boards are mounted on the flue protection board; openings of the Y-shaped fork face the sealing boards; and a sealing ring clinging to the peripheral surfaces of the sealing boards is arranged between the openings of the Y-shaped fork and the sealing boards.

Description

technical field [0001] The invention relates to the technical field of wall-penetrating steel structure sealing of flues, in particular to a sealing structure of a load-bearing beam passing through a flue guard plate. Background technique [0002] In the design of steel structure with flue, it is often encountered that there is a heating surface for heat exchange in the flue, which needs to be supported or hung on the beam, and the beam then transmits the load to the steel frame through the guard plate passing through the flue. . Metal expansion joints have also been used to seal before, but this kind of metal fatigue problem will cause cracks for a long time, especially for flues with frequent temperature changes, it is more likely to be damaged quickly. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention provides a sealing structure for the load-bearing beam passing through the flue guard plate, which is not only sealed but does...
