Description

Technical Field

[0001] The invention relates to a device commonly used in buildings for distributing the weight of a smoke duct on a building body. Background Art

[0002] The smoke exhaust ducts used in existing buildings are generally square tubular structures. The smoke exhaust ducts of this structure are generally consistent with the height of the floors, and the height is generally above 2.7 meters. The direct connection parts of the upper and lower smoke exhaust ducts are generally located in the plane where the floor is located. Since each section of the smoke exhaust duct has a certain weight, the existing buildings are generally more than ten or dozens of floors. After the smoke exhaust ducts of all floors are connected together, the smoke exhaust ducts located at the relatively bottom will be collapsed. Therefore, every 3-4 floors, the bottom of the smoke exhaust duct on the relatively upper floor is generally set on the top of the floor where the smoke duct installation hole is installed. The supporting parts on the board prevent the exhaust gas pipe located at the bottom layer from collapsing. The supporting parts are generally made of angle steel or channel steel. This installation method has the following disadvantages: due to the presence of supporting parts at the direct connection between the upper and lower exhaust gas pipes, there is a gap at the connection between the upper and lower exhaust gas pipes, which is prone to leakage, exposure, and poor sealing during the later grouting process; at the same time, since the supporting parts are metal parts, they have different thermal shrinkage coefficients from the exhaust gas pipes, causing cracks in the cement grouting seal at the connection between the exhaust gas pipes, which is prone to smoke and odor, and is very likely to cause leakage at the connection between the exhaust gas pipes in the later stage. There is no device or component in the prior art that can distribute the weight of the smoke duct on a specific building. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a device for distributing the weight of a smoke duct on a building.

[0004] In order to solve the above technical problems, the present invention includes an angle fixing piece, a connecting plate is hinged on the relative outer side surface of the angle fixing piece, the upper end of the connecting plate is hinged with an angle locking piece corresponding to the upper and lower parts of the angle fixing piece, the angle fixing piece is locked on the outer wall of the smoke duct by a clamp, and a stretching rod is provided between the side of the connecting plate relative to the lower end away from the angle fixing piece and the building body, which enables the connecting plate to rotate around the angle fixing piece and lock the angle locking piece on the outer wall of the smoke duct for a second time.

[0005] A mutually connected lifting mechanism is provided between the lower end of the stretching rod and the connecting plate.

[0006] The lifting mechanism comprises a lifting hole arranged on the connecting plate, and the lower end of the stretching rod is provided with a hook correspondingly connected to the lifting hole; the upper end of the stretching rod is provided with a locking piece which is adjusted up and down along the stretching rod.

[0007] The lifting mechanism comprises a lifting hook arranged on the connecting plate, and the lower end of the stretching rod is provided with a lifting hole corresponding to the lifting hook; the upper end of the stretching rod is provided with a locking piece which is adjusted up and down along the stretching rod.

[0008] A notch for installing a clamp is provided approximately in the middle of the outer corner of the angle fixing piece.

[0009] The inner side surfaces of the angle fixing piece and the angle locking piece are rough surfaces.

[0010] The top of the angular locking piece is provided with an inwardly curved edge and / or the top of the angular fixing piece is provided with an inwardly curved edge.

[0011] The inward extension distance of the curved edge gradually decreases from the intersection of the two inner wall surfaces outwards.

[0012] The upper end of the stretching rod is connected to a cross arm placed at a smoke duct mounting hole or to a frame of a building.

[0013] After adopting the above structure, the angle fixing part is locked on the outer wall of the smoke duct by the clamp, and then the connecting plate is pulled by the stretching rod to lock the angle locking part on the outer wall of the smoke duct for the second time, thereby dispersing the weight of the smoke duct body to the building body on a specific floor, completely solving the problem that the existing smoke duct needs to be supported by supporting parts, which makes it easy to leak grout, expose grout, and poor sealing in the later grouting process. A notch for installing a clamp is provided in the approximate middle part of the outer angle of the angle fixing piece, which can prevent relative sliding between the angle fixing piece and the clamp; the inner side surfaces of the angle fixing piece and the angle locking piece are rough surfaces, which can prevent relative sliding between the angle fixing piece and the angle locking piece and the outer wall surface of the flue gas duct; and the tops of the angle locking piece and the angle fixing piece are provided with inwardly bent edges, which can increase the friction between the angle fixing piece and the angle locking piece and the outer wall surface of the flue gas duct, increase the lifting force between the angle fixing piece and the angle locking piece relative to the outer wall surface of the flue gas duct, and further prevent relative sliding between the angle fixing piece and the angle locking piece and the outer wall surface of the flue gas duct. The device distributes the weight of the smoke duct on the building body to prevent the smoke exhaust duct on the relatively lower floor from being crushed, and no joint gap will appear at the upper and lower joints of the smoke duct, which is convenient for subsequent grouting and sealing. The device is located in the floor slab. After subsequent grouting and sealing, the device and its stretching rod form a whole with the building body, which increases the density, prevents smoke and odor from bleeding, and effectively prevents water leakage at the joints of the smoke exhaust duct.

A stretching rod 8 is provided between the side of the connecting plate 4 that is away from the angle fixing part 1 at the relative lower end and the building body, which enables the connecting plate 4 to rotate around the angle fixing part 1 and lock the angle locking part 3 on the outer wall of the flue gas duct for the second time, and a mutually connected pulling mechanism is provided between the lower end of the stretching rod 8 and the connecting plate 4. See also Figure 1The lifting mechanism includes a lifting hole 7 arranged on the side of the connecting plate 4 away from the angle fixing piece 1 at the lower end relative to the connecting plate 4. The geometric shape of the connecting plate 4 is roughly triangular. The corners of the connecting plate 4 are provided with circular holes, one of which is used as the lifting hole 7, and the other two circular holes are hinged with the angle fixing piece 1 and the angle locking piece 3 through pins respectively. The lifting hole 7 is close to the end of the connecting plate 4 hinged with the angle fixing piece 1, that is, the lifting hole 7 is located at the lower end of the connecting plate 4 away from the side of the angle fixing piece 1, and the lower end of the stretching rod 8 is provided with a bent hook connected to the lifting hole 7 accordingly; the lifting mechanism can also be a lifting hook arranged on the connecting plate 4, and the aforementioned lifting hole 7 can be set to a groove shape. At this time, the aforementioned lifting hole 7 is inverted U-shaped, and the lower end of the stretching rod 8 is provided with a lifting hole corresponding to the lifting hook. Of course, the lifting mechanism can also be other well-known structures. The upper end of the stretching rod 8 is provided with a locking piece that can be adjusted up and down, and the locking piece can be a nut, that is, the upper end of the stretching rod 8 has a threaded section, and a cross arm 9 is provided at the flue gas duct mounting hole 13, and the cross arm 9 can be located at the corner of the flue gas duct mounting hole 13 or on two opposite hole walls, and the cross arm 9 is located on the top surface of the floor, and the upper end of the stretching rod 8 is connected to the cross arm 9. Of course, the stretching rod 8 can also be any other known structure, such as an oblique pull lock of an oblique pull rope, through which the stretching rod 8 can drive the connecting plate 4 to rotate around the angle fixing piece 1 and lock the angle locking piece 3 on the outer wall of the flue gas duct for the second time, and the upper end of the stretching rod 8 can also be connected to the frame of the building, such as a load-bearing column; the upper end of the stretching rod 8 can also be connected to the steel bar in the flue gas duct mounting hole 13. The connecting plate 4 that connects the angle fixing piece 1 and the angle locking piece 3 can also be other structures, such as a metal rod bent, and is respectively hinged to the hinged mounting seat of the angle fixing piece 1 and the angle locking piece 3, and is conveniently connected to the lower end of the stretching rod 8. A notch 6 for installing the clamp 2 is provided in the approximate middle part of the outer angle of the angle fixing piece 1, which can prevent relative sliding between the angle fixing piece 1 and the clamp 2. The hinged part of the angle fixing piece 1 is generally located below the notch 6, that is, below the clamp 2; the inner side surfaces of the angle fixing piece 1 and the angle locking piece 3 are rough surfaces, which can be pockmarked, nail-shaped or serrated, which can prevent relative sliding between the angle fixing piece 1 and the angle locking piece 3 and the outer wall of the flue gas duct. In order to increase the friction between the angle fixing piece 1 and the angle locking piece 3 and the outer wall of the flue gas duct, and to increase the pulling force between the angle fixing piece 1 and the angle locking piece 3 relative to the outer wall of the flue gas duct, an inwardly curved edge 14 is provided at the top of the angle locking piece 3, and an inwardly curved edge 14 is also provided at the top of the angle fixing piece 1. The inwardly extending distance of the curved edge 14 gradually decreases from the intersection of the two inner wall surfaces to the outside, that is, the inwardly extending distance of the curved edge 14 gradually decreases from the intersection of the two side walls of the angle locking piece 3 to the two sides in the width direction of the angle locking piece 3, and gradually decreases from the intersection of the two side walls of the angle fixing piece 1 to the two sides in the width direction of the angle fixing piece 1. The curved edge 14 can also be further processed into a sawtooth shape or a nail shape, and the inwardly extending distance of the curved edge 14 relative to the inner wall surfaces of the angle fixing piece 1 and the angle locking piece 3 is generally 1-2 mm.When the angle fixing piece 1 and the angle locking piece 3 are locked on the outer wall of the flue gas duct for lifting the flue gas duct, the bent edge 14 partially penetrates into the outer wall of the corner of the flue gas duct, further preventing relative sliding between the angle fixing piece and the angle locking piece and the outer wall of the flue gas duct.

[0020] Figure 4 The figure shows a schematic diagram of the flue gas duct structure between upper and lower adjacent floors. The building is composed of a frame and a floor slab 11. The floor slab 11 is provided with a flue gas duct mounting hole 13. The upper and lower butt joints of the flue gas duct 12 are located in the flue gas duct mounting hole 13. The top of the flue gas duct 12 at the relatively lower level is provided with an angle fixing piece 1 and an angle locking piece 3 locked on the outer wall of the flue gas duct. An adjustable stretching rod 8 is provided between the angle fixing piece 1 and the building. The upper end of the stretching rod 8 can be connected to a cross arm supported at the flue gas duct mounting hole 13, or can be connected to the frame of the building, such as a load-bearing column. The weight of the flue gas duct is distributed on the set building through the angle fixing piece 1 and the angle locking piece 3. On the upper side, it is prevented that the smoke exhaust gas duct located at the relatively lower layer will be collapsed, and there will be no butt joint gaps at the upper and lower joints of the smoke duct, which is convenient for later grouting and sealing. The angle fixing parts 1 and the angle locking parts 3 are located in the smoke duct mounting holes 13. After the later grouting and sealing, the angle fixing parts 1 and the angle locking parts 3 and their stretching rods form a whole with the building body. At this time, the smoke duct mounting holes 13 are grouting The grouting forms an integrated structure with the floor and the outer wall of the smoke duct, the upper and lower butt joints of the smoke duct 12 and the angle fixing parts 1, the angle locking parts 3, and the stretching rods 8 are all located in the floor, which can increase the density, prevent the occurrence of smoke and odor, and effectively prevent water leakage at the joints of the smoke exhaust duct. Of course, the upper and lower docking parts of the flue duct 12 can be located on the upper or lower side of the floor, and the angle fixings 1 and the angle locking parts 3 can be locked at any position of the outer wall of the flue duct, such as the middle section of the outer wall of the flue duct, the top of the outer wall of the flue duct 12 on the lower layer, or the bottom of the outer wall of the flue duct 12 on the upper layer. It is only necessary to ensure that the angle fixings 1 and the angle locking parts 3 are located in the flue duct mounting holes 13. After the flue duct mounting holes 13 are grouting to form an integrated structure with the floor and the outer wall of the flue duct, the angle fixings 1 and the angle locking parts 3 are both located in the floor. The angle fixings with a specific structure are used, and the angle fixings are locked on the outer wall of the top of the flue duct through a clamp to prevent sliding between the angle fixings 1 and the flue duct, thereby distributing the weight of the flue duct body to the building body of a specific floor, and completely solving the problem that the existing flue duct needs to be supported by a supporting member, which causes leakage, exposure of grout, and poor sealing during the later grouting process.
