Curtain wall refuge floor drainage structure and construction method thereof

Abstract

This invention discloses a drainage structure and construction method for a refuge floor in a curtain wall, comprising two parts: a sloping drainage system of a water guide plate within the building and a drainage system for the glass curtain wall. The water guide plate within the building is fixed to the concrete curb of the building's exterior corridor via a keel layer and a raised platform. A waterproof membrane is laid flat on top of the keel layer, and then the water guide plate is fixed on top of the membrane. The water guide plate requires sloping to ensure self-drainage. The joints of the water guide plate are treated with silicone sealant and silicone strips to ensure a tight seal. The drainage of the glass curtain wall involves water channels installed on aluminum alloy beams. Rainwater discharged from the sloping surface of the water guide plate within the building is collected through these channels into the drainage channels of the aluminum alloy columns, ultimately flowing into the curtain wall's drainage system. This invention solves the problem of rainwater easily entering the building from the ventilation openings of the refuge floor in the curtain wall of high-rise buildings.

Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a curtain wall refuge floor drainage structure and its construction method. Background Technology

[0002] With urban development, the number of super high-rise buildings is constantly increasing; however, the probability of fires is also greatly increased, making fire safety in super high-rise buildings particularly important. When a building's height exceeds 100 meters, refuge floors should be provided for fire safety reasons. Unitized curtain walls are becoming increasingly common in super high-rise buildings. In refuge floors, ventilation openings need to be installed in the curtain wall glass to ensure smoke and air extraction. Rainwater can enter the building through these ventilation openings, affecting its usability.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a curtain wall refuge floor drainage structure and its construction method are provided to solve the problem that rainwater can easily enter the building from the ventilation openings of the refuge floor of a super high-rise building.

[0005] To achieve the above objectives, a curtain wall refuge floor drainage structure is provided, comprising:

[0006] A reverse retaining wall is formed on the floor slab of the building structure. The reverse retaining wall is positioned opposite to the ventilation openings on the glass curtain wall. The glass curtain wall includes unit glass panels, horizontal beams, and multiple columns. The columns are installed on the exterior of the building structure and are arranged along the circumferential direction of the building structure. Multiple horizontal beams connect adjacent columns. The unit glass panels are installed on the columns and the horizontal beams. Vertically arranged drainage channels are formed in the columns, and water supply channels are formed in the horizontal beams. One end of the water supply channel penetrates the top surface of the horizontal beam, and the other end of the water supply channel connects to the drainage channel.

[0007] A raised platform is poured into the floor slab and abuts against the outside of the curb. The top surface of the raised platform is inclined, and the lower side of the top surface of the raised platform faces the top surface of the crossbeam of the glass curtain wall. The upper side of the raised platform extends obliquely inward and upward to the curb.

[0008] A waterproof layer is laid on the top surface of the raised platform and overlaps the outside of the inverted embankment.

[0009] A water guide plate is laid on the waterproof layer, and the lower side of the water guide plate extends above the top surface of the crossbeam and is sealed to the inner side of the top surface of the crossbeam.

[0010] Furthermore, a keel layer is laid on the top surface of the padding layer, one side of the keel layer is connected to the anti-sill by anchors, the waterproof membrane is laid on the keel layer, and the water guide plate is installed on the keel layer by fasteners.

[0011] Furthermore, a non-removable template is vertically installed along the outer edge of the floor slab, forming a pouring space between the non-removable template and the anti-sill. The upper and lower parts of the non-removable template extend toward the anti-sill to form flanges. The other side of the keel layer overlaps with the upper flange of the non-removable template. Concrete is poured into the pouring space to solidify and form a raised floor.

[0012] Furthermore, the slope of the water guide plate is 5°.

[0013] This invention provides a construction method for a drainage structure of a refuge floor in a curtain wall, comprising the following steps:

[0014] Glass curtain walls are constructed on the exterior of the building structure.

[0015] A raised curb is cast into the floor slab of the building structure, so that the raised curb is positioned opposite to the ventilation opening on the glass curtain wall;

[0016] A raised floor is formed by pouring concrete into the floor slab, such that the raised floor abuts against the outside of the anti-sill. The top surface of the raised floor is inclined, the lower side of the top surface of the raised floor faces the top surface of the horizontal beam of the glass curtain wall, and the upper side of the raised floor extends obliquely inward and upward to the anti-sill.

[0017] A waterproof layer is laid on the top surface of the raised platform, and the waterproof layer is folded up and overlapped on the outside of the inverted embankment;

[0018] A water guide plate is laid on the waterproof layer, such that the lower side of the water guide plate extends above the top surface of the crossbeam and is sealed to the inner side of the top surface of the crossbeam.

[0019] The beneficial effects of this invention are as follows: the curtain wall refuge layer drainage structure of this invention consists of two parts: the sloping drainage of the water guide plate inside the building and the drainage of the glass curtain wall. The water guide plate inside the building is fixed to the concrete curb of the building's outer corridor via a keel layer and a pad layer. A waterproof membrane is laid flat on top of the keel layer, and then the water guide plate is fixed on top of the waterproof membrane. The water guide plate needs to be sloped to ensure self-drainage. The joints of the water guide plate are treated with silicone sealant and silicone strips to ensure a sealing effect. The drainage of the glass curtain wall is achieved by setting water channels on the aluminum alloy beams. Rainwater discharged from the sloping surface of the water guide plate inside the building is collected through the water channels on the beams into the drainage channels of the aluminum alloy columns, and finally collected into the curtain wall's drainage system. This curtain wall refuge layer drainage structure of the present invention effectively overcomes the drainage and waterproofing problems of refuge curtain wall systems in super high-rise buildings. The curtain wall refuge layer drainage structure of this invention is simple to process, convenient to construct, and has a low cost. Attached Figure Description

The upper side of the raised platform 2 extends obliquely inward and upward to the retaining wall 1.

[0031] Waterproof layer 3 is laid on the top surface of the raised platform 2. Waterproof layer 3 is a waterproof membrane. It is turned up and overlapped on the outside of the retaining wall 1.

[0032] The water guide plate 4 is laid on the waterproof layer 3. The lower side of the water guide plate 4 extends above the top surface of the crossbeam 62 and is sealed to the inner side of the top surface of the crossbeam 62.

[0036] This invention provides a construction method for a drainage structure of a refuge floor in a curtain wall, comprising the following steps:

[0037] S1, glass curtain wall 6, constructed on the exterior of the building structure.

[0038] S2. A reverse curb 1 is cast on the floor slab 7 of the building structure, so that the reverse curb 1 is positioned opposite to the ventilation opening on the glass curtain wall 6.
