Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, and in particular relates to an air shaft structure that can be used as a temporary garbage chute. Background Art
[0002] From the start of secondary structure construction, a large amount of construction waste is generated daily on each floor, including broken bricks, concrete blocks, used screws, formwork timbers, and dust. Each floor can generate several wheelbarrows of construction waste daily, necessitating dedicated personnel to remove the waste, which inevitably increases labor costs and affects the efficiency of construction elevators. To address this, the present invention designs a ventilation shaft structure that can serve as a temporary garbage chute. By utilizing the ventilation shaft outside the building as a temporary garbage chute, garbage from the floors can be directly dumped onto the first floor and removed from the garbage pit for disposal. Utility Model Content
[0003] In response to the deficiencies in the prior art, the utility model provides an air shaft structure that can be used as a temporary garbage chute, which enables construction waste on a floor to be more conveniently transported to the outdoors while ensuring safety and efficiency.
[0004] The utility model achieves the above technical objectives through the following technical means.
[0005] A ventilation shaft structure that can be used as a temporary garbage chute. When the ventilation shaft leads from the basement to the top floor or roof layer above, a temporary cover plate is cast on the first floor of the ventilation shaft, and the temporary cover plate and the formwork below the projection range of the bottom of the beams around it are not removed, so as to diffuse the impact force of the garbage falling from the building and eventually transmit it to the basement floor; the side of the first floor of the ventilation shaft facing the outdoor garbage pool is not built, and an inclined slide is constructed on the top of the temporary cover plate. A vibration isolation layer is provided on the three walls of the ventilation shaft within the construction range of the slide; ventilation shafts above one floor are provided with a garbage dumping port at the bottom, and a cover plate is hingedly installed at the garbage dumping port; when the building structure is not designed with a basement, the floor slab at the bottom of the ventilation shaft is reinforced, including thickening the cross-section and adding steel bars.
[0006] Furthermore, the temporary sealing plate has a thickness of 200 mm and is equipped with C12@150 double-layer bidirectional steel bars.
[0007] Furthermore, the slideway has an inclination angle of 30°.
[0008] Furthermore, the vibration isolation layer is made of an 80 mm thick extruded polystyrene board.
[0009] Furthermore, the interior of the slide is filled with aerated blocks, and the surface layer of the slide is a reinforced concrete surface layer.
[0010] Furthermore, the concrete surface layer has a thickness of 100 to 150 mm, is provided with a single layer of C12@150 steel bars, and the reinforcement is located on the top surface of the surface layer.
[0011] Furthermore, the garbage dumping port is 500 mm wide and 400 mm high.
[0012] Furthermore, the cover plate is made of patterned steel plate.
[0013] Furthermore, the garbage pool located outdoors has walls built with aerated blocks, the top of the wall is 500mm higher than the top surface of the slide and not less than 1800mm, and the top of the garbage pool wall is installed with automatic sprinkler equipment.
[0014] The present invention has the following beneficial effects:
[0015] The utility model uses the improved design of the air shaft outside the building to serve as a temporary garbage chute, so that the garbage in the floors can be directly dumped into the first floor and finally transported away from the garbage pool for treatment. There is no need for special personnel to remove the garbage, which saves time and effort and helps to reduce construction costs. It also does not occupy the elevators in the building, which helps to improve construction efficiency and shorten the construction period. Under the premise of ensuring safety and efficiency, the utility model realizes a more convenient transportation of construction waste in the floors to the outdoors. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.
[0023] like Figures 1 to 5As shown, the air shaft structure that can be used as a temporary garbage chute described in the present invention is an improved design based on the traditional air shaft structure.
[0024] like Figure 1 、 2 As shown, for the ventilation shaft leading from the basement to the top floor or roof, a temporary reinforced concrete cover 1 is cast on the first floor of the shaft to provide temporary sealing. This cover is 200mm thick and features double-layer C12@150 bidirectional steel bars, with the same concrete grade as the beams and slabs. Because falling construction waste can generate significant impact loads, after the temporary cover 1 is cast, the formwork 2 surrounding it and below the projection of the beam bottoms is not removed. This helps to diffuse the impact force, ultimately transmitting it to the base slab.
[0025] like Figure 1 、 2 As shown, during the secondary structure construction phase, the air shaft is first constructed, and the outdoor side of the first floor is not constructed so that the garbage can be transported to the garbage pool 8 next door; an inclined slide 3 is constructed on the top of the temporary cover 1, and the slide 3 has an inclination angle of 30°, which is more conducive to the concentration of garbage. Before the construction of the slide 3, an 80mm thick extruded polystyrene board vibration isolation layer 4 is provided on the three walls of the air shaft within the construction range of the slide 3, and the interior of the slide 3 is filled with aerated blocks 5. The surface layer of the slide 3 is a concrete surface layer with a thickness of 100-150mm, and is equipped with a C12@150 single-layer steel bar, and the reinforcement is located on the top surface of the surface layer.
[0026] like Figure 3 、 4 As shown in Figures 5 and 6, for ventilation shafts with more than one floor, one or two garbage dumping openings 6 are provided at the bottom of each ventilation shaft. These openings 6 are 500 mm wide and 400 mm high, and hingedly mounted with a patterned steel plate as a cover 7 that can be flipped open. By limiting the size of the garbage dumping openings 6, larger and heavier garbage can be prevented from falling as a whole. Bags of lightweight construction waste, such as formwork and wood, can be discarded as a whole. Bags of broken bricks should be discarded in batches, and larger pieces should be further crushed before disposal.
[0027] When the building structure does not have a basement, the air shaft leads from the first floor to the top floor or roof layer. At this time, there is no need to set up a temporary cover plate 1 or retain the formwork 2. The floor slab at the bottom of the air shaft can be strengthened, such as thickening the section, adding steel bars, etc. The rest of the structural design remains unchanged.
[0028] like Figures 1 to 5 As shown, the garbage pool 8 located outdoors has walls built with aerated blocks 5. The top of the wall is 500mm higher than the top surface of the slide 3 and not less than 1800mm. The corner and end structural columns of the wall and the reinforced concrete top of the wall should comply with relevant specifications.
[0029] The garbage pit 8 is 2500mm deep and 3000mm wide, which can be adjusted according to actual needs. The opening of the garbage pit 8 should be away from the pipe well opening. Automatic sprinkler equipment 9 must be installed on the top of the garbage pit 8 to prevent falling garbage from generating large amounts of dust. The garbage pit 8 must be cleaned uniformly every evening after work to prevent garbage from falling and injuring people during the cleaning process.
[0030] The embodiments described are preferred implementations of the present invention, but the present invention is not limited to the above-mentioned implementations. Any obvious improvements, replacements or modifications that can be made by those skilled in the art without departing from the essential content of the present invention are within the scope of protection of the present invention.
