Description

Technical Field

[0001] The utility model relates to the technical field of flue construction, in particular to a high-rise flue installation and blocking device. Background Art

[0002] In residential construction projects, the focus of residential quality has gradually shifted to leakage issues. From the results of the owners' inspection of building quality, it was found that common leakage hazards include the flue holes in the bathroom and kitchen floors. Effective prevention and control measures are often not taken, and air and smoke leaks often occur at the junction of the flues. The verticality of the flue parts cannot be guaranteed. Judging from previous design drawings and on-site construction conditions, the main problem with the flue holes in the floor slabs is that when the flue holes are poured and filled and the counter-ridges are poured, there is a construction joint between the flue holes and the floor structure. Not only are there many processes, but it also brings huge leakage risks in later use. Summary of the Invention

[0003] The purpose of the utility model is to solve the problems raised in the background technology and to provide a high-rise flue installation and blocking device.

[0004] The technical solution of the utility model to achieve the above purpose is:

[0005] A high-rise flue installation and sealing device comprises a flue card slot, a structural plate and a finished flue arranged on each floor, the flue card slot is fixedly connected to the structural plate, the bottom end of the finished flue is fixed in the flue card slot, and an organic fireproof sealing mud is arranged between the flue card slot and the finished flue; EVA fireproof and flame-retardant plugging tapes are fixed at the flue openings at both ends of the finished flue, a card slot is fixed at the top of the finished flue, a vertical positioner is fixed at the bottom of the finished flue, a vertical line fixing block is fixed on the vertical positioner, a steel wire is connected to the vertical line fixing block, and a gravity ball is connected to the other end of the steel wire.

[0006] The bottom flue opening of the upper finished flue is butted against the top flue opening of the lower finished flue, and the gravity ball at the bottom of the upper finished flue is clamped in the clamping groove at the top of the lower finished flue.

[0007] Preferably, the flue slot and the structural plate are integrally cast using a reinforced concrete structure.

[0008] Preferably, the gap between the bottom end of the finished flue and the flue slot is 20 mm.

[0009] Preferably, waterproof mortar is provided between the flue slot and the finished flue.

[0010] Preferably, a waterproof layer is provided on the outside of the flue slot, and the waterproof layer is fixedly connected to the flue slot.

[0011] The utility model provides a high-rise flue installation and blocking device, which has the following beneficial effects:

[0012] Through its structural design, this device requires that before the finished flue needs to be installed, the flue groove is first cast on the structural plate, and then the finished flues are installed. During installation, the vertical positioner is pasted on the finished flue of the upper layer, and the pasting position is positioned in advance on the finished flue. After the vertical positioner is pasted on the upper finished flue, the position of the upper finished flue is adjusted. Under the action of gravity, the gravity ball located below the vertical fixing block will be fixed in a vertical position by the wire rope. When the gravity ball is fixed to the positioning groove on the finished flue of this layer, the finished flues of the upper and lower layers are connected. The connection is adhered with EVA fire-retardant sealing tape for flexible connection, so that there will be no gap at the junction, and it is tightly sealed to prevent the finished flue from leaking air or smoke at the junction. After the finished flue is connected, the gap between the finished flue and the flue groove is sealed with organic fire-proof sealing mud to complete the installation and construction of the high-rise flue. Compared with the existing technology, the utility model reserves a flue slot through a cast-in-place structure, and the finished flue is installed in the flue slot at a later stage. The gap between the finished flue and the flue slot is sealed with organic fireproof sealing mud, and vertical positioners are installed on the upper finished flue and the lower finished flue to ensure the verticality of the finished flue during installation.

When the gravity ball 10 is fixed to the positioning groove 7 on the finished flue 4 of this layer, the finished flues 4 of the upper and lower layers are connected. The connection is glued with EVA fire-retardant leak-proof tape 5 for flexible connection. The flexible connection improves the seismic performance of the flue system, reduces cracks caused by building vibration or temperature changes, and prevents gaps at the junction. The seal is tight to prevent the finished flue 4 from leaking air and smoke at the junction. After the finished flue 4 is connected, the gap between the finished flue 4 and the flue slot 1 is sealed with organic fire-proof sealing mud 3 to complete the installation and construction of the high-rise flue. Leakage can be effectively prevented by adding waterproof mortar 11 to the gap between the finished flue 4 and the flue slot 1.
