Description

Technical Field

[0001] The utility model belongs to the technical field of integral hoisting of air ducts, and in particular relates to an integral lifting and hoisting bracket structure for a heat-insulating air duct. Background Art

[0002] At present, the smoke exhaust duct needs to be connected with angle steel flanges, and the outside of the duct needs to be wrapped with fireproof materials that meet the fire resistance limit. The installation of the smoke exhaust duct generally adopts the construction method of first installing the hanging rod, then lifting and connecting the duct section by section, and at the same time installing the angle steel cross arm under the duct to connect and fix the duct with the hanging rod.

[0003] This method requires multiple people to work together, which is time-consuming and laborious. In addition, the flatness and straightness of the duct cannot be guaranteed because the duct is lifted and connected section by section. After the duct is hoisted, the fireproof wrapping material of the duct needs to be constructed at a height, which not only affects the construction efficiency but also poses a safety hazard. Due to the presence of angle steel crossbeams, the fireproof material needs to be disconnected, which not only destroys the continuity, but also affects the fireproof performance, and the molding is not beautiful. For this reason, we propose an overall lifting and hoisting bracket structure for the thermal insulation duct to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a structure of an integral lifting and hanging bracket for a heat-insulating air duct, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integral lifting and hoisting bracket structure of an insulated air duct, comprising a hanging rod, an assembly platform and a plurality of nuts, wherein the hanging rod is hoisted on a concrete floor, the lower end of the hanging rod is threadedly connected to a flat connector, the end of the hanging rod is threadedly connected to a nut, the side end of the flat connector is threadedly connected to two extended screws, the adjacent ends of the two extended screws are threadedly connected to connecting foot blocks, the two connecting foot blocks are connected to a galvanized air duct by rivets, the surfaces of the two galvanized air ducts are provided with angle steel flanges, and the angle steel flanges are arranged between the two connecting foot blocks.

[0006] Preferably, the assembly platform is arranged on the lower side of the galvanized air duct.

[0007] Preferably, the concrete floor is fixedly connected to two pulleys, and steel wire ropes are provided on the surfaces of the two pulleys.

[0008] Preferably, the ends of the two steel wire ropes are connected to the assembly platform.

[0009] Preferably, the surface of the galvanized air duct is coated with fireproof material.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] Before the galvanized air duct is raised, the flat connector is fixed with nuts on the extended screws on both sides of the connecting foot block above the angle steel flange of the galvanized air duct. The galvanized air duct can be hoisted by connecting it with the hanging rod through the nuts. After adding this connector, the galvanized air duct and the hanging rod can be quickly connected, and the angle steel crossarm under the galvanized air duct can be eliminated to save materials. Moreover, this connector is installed at the angle steel flange of the galvanized air duct, which does not affect the installation of the fireproof wrapping material of the air duct.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 5 The utility model provides a thermal insulation air duct integral lifting and hoisting bracket structure, including a hanging rod 1, an assembly platform and a plurality of nuts 3. The hanging rod 1 is hoisted on a concrete floor slab, and a flat connector 2 is threadedly connected to the lower end of the hanging rod 1. The end of the hanging rod 1 is threadedly connected to a nut 3. The side end of the flat connector 2 is threadedly connected to two lengthened screws 4. The adjacent ends of the two lengthened screws 4 are threadedly connected to connecting foot blocks 6. The two connecting foot blocks 6 are connected to galvanized air ducts 7 through rivets 5. The surfaces of the two galvanized air ducts 7 are sleeved with angle steel flanges 8, and the angle steel flanges 8 are arranged between the two connecting foot blocks 6.

[0022] In this embodiment, the ends of the two steel cables are connected to the assembly platform.

[0023] In this embodiment, the surface of the galvanized air duct 7 is coated with fireproof material.

[0024] Furthermore, the installation of the air duct system is changed from first installing the hanging bar 1, then lifting and connecting the galvanized air duct 7 section by section, and installing an angle steel crossarm under the galvanized air duct 7 to connect and fix the galvanized air duct 7 with the hanging bar 1, and then insulating the galvanized air duct 7, to first assembling the galvanized air duct 7 on the ground, then insulating the galvanized air duct 7, and lifting the whole after completion. The galvanized air duct 7 can be quickly hoisted by connecting the flat connector 2 installed on the angle steel flange 8 with the hanging bar 1. This construction method not only improves the construction efficiency, but also avoids high-altitude operations, improves construction safety, and prevents secondary damage to insulation. After adding this flat connector 2 to the angle steel flange 8, the galvanized air duct 7 can be quickly connected to the hanging bar 1, and the angle steel crossarm under the galvanized air duct 7 can be eliminated to save materials. Moreover, this connector is installed at the angle steel flange 8 and does not affect the installation of the galvanized air duct 7.

[0025] The working principle and use process of this utility model:

[0026] First, the pipelines in the construction area are comprehensively arranged through BIM, and the position and direction of the installed smoke exhaust duct are determined. The galvanized duct 7 is cut and produced according to the BIM arrangement model. After the galvanized duct 7 is processed and brought to the site, it is assembled on the ground operating platform. After the assembly is completed, the galvanized duct 7 is directly adjusted on the operating platform to ensure the flatness and straightness. The two bolt eyes on the outside of the connecting foot block 6 at the upper end of the angle steel flange 8 are connected to the nut with the extended screw 4, and the processed flat connector 2 is installed on the outside of the nut 3. The flat connector 2 is connected to the extended screw 4 through the bolt eyes on both sides, and a nut is added on the outer side. 3, after the flat connector 2 and the angle steel flange 8 are connected, the fireproof wrapping material of the galvanized air duct 7 can be constructed. The fireproof material can cover the angle steel flange 8 of the galvanized air duct 7, leaving only the flat connector 2 on the top, which is convenient for connecting with the hanger 1. After the galvanized air duct 7 is wrapped with the fireproof material, the galvanized air duct 7 can be installed in place. According to the BIM pipeline layout, the installation position and height of the galvanized air duct 7 can be determined, and the position and length of the hanger 1 can be determined according to the position of the connector on the angle steel flange 8. When the construction of the hanger 1 is completed, the operating platform is lifted as a whole by the pulley, and the hanger 1 and the flat connector 2 are connected by the nut 3 to put the galvanized air duct 7 in place.
