Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to the construction of duct insulation layers, specifically a portable duct insulation layer precision installation and fixing clamp. Background Technology

[0002] In recent years, the construction industry has been developing rapidly, and society's requirements for building quality are also increasing. In buildings, air ducts play a crucial role in providing fresh air and removing harmful gases, essentially acting as a "breathing" system. For air ducts that carry temperature, insulation is often required to ensure that the internal temperature of the ducts is minimized during transportation and that the internal gas remains unaffected by external temperatures.

[0003] Currently, most duct insulation installations involve installing rock wool insulation material on the outside of the duct. During installation, insulation nails are first fixed to the duct using structural adhesive. The rock wool insulation is then pressed onto the nails, allowing the nails to pass through, and finally secured with round clips to prevent detachment. However, in practice, this method often results in the round clips coming loose, causing the rock wool insulation to peel or detach, affecting the duct's insulation performance and appearance. Furthermore, detached clips can expose the insulation nails, increasing the risk of injury to workers.

[0004] Therefore, it is necessary to develop a more robust method for fixing rock wool insulation materials, which can both ensure that the rock wool insulation materials are firmly fixed and facilitate on-site construction. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art by providing a portable, precise installation and fixing clamp for duct insulation layers. This clamp can assist in the installation of rock wool insulation materials and changes the fixing mode of rock wool insulation materials. It replaces the traditional circular buckle with a new fixing connector composed of nuts and screws, that is, it uses a threaded connection instead of a buckle connection, thereby strengthening the fixing strength of the rock wool insulation materials.

[0006] This utility model is achieved through the following technical solution:

[0007] A portable duct insulation layer precision installation and fixing clamp includes a connecting plate, an inner clamp, an outer clamp, and a fixing connector.

[0008] The inner edge of the connecting plate is fixedly connected to one end edge of the inner clamping plate, and the connecting plate and the inner clamping plate are set perpendicularly.

[0009] The outer side plate edge of the connecting plate is hingedly connected with one end plate edge of the outer side clamping plate, and a plurality of positioning through holes are formed in the outer side clamping plate along the length direction of the outer side clamping plate.

[0010] The inner side clamping plate is composed of an inner side upper clamping plate and an inner side lower clamping plate, and a clamping gap is formed between the inner side upper clamping plate and the inner side lower clamping plate.

[0011] The fixing connecting pieces are provided in multiple groups, the number of the groups of the fixing connecting pieces is same as the number of the positioning through holes on the outer side clamping plate, and the multiple groups of the fixing connecting pieces are provided in one-to-one correspondence with the multiple positioning through holes; the fixing connecting piece comprises a positioning nut located at the inner side, a fixing nut located at the outer side and a screw rod located at the middle part, the positioning nut is clamped in the clamping gap between the inner side upper clamping plate and the inner side lower clamping plate; the fixing nut is threadedly connected on the screw rod; the screw rod is arranged between the inner side clamping plate and the outer side clamping plate, the inner side end of the screw rod is threadedly connected with the positioning nut, and the outer side end of the screw rod is arranged to pass through the corresponding positioning through hole on the outer side clamping plate.

[0012] Further, a gasket is sleeved on the screw rod and used in cooperation with the fixing nut.

[0013] Further, a pin hole is arranged at the middle position of the outer side plate edge of the connecting plate, and a pin hole is arranged at the upper part and the lower part of one end plate edge of the outer side clamping plate; the two pin holes on the outer side clamping plate are arranged in butt joint with the one pin hole on the connecting plate, and a pin shaft is arranged in the three pin holes after butt joint.

[0014] Further, a U-shaped handle is fixed on the connecting plate.

[0015] Compared with the traditional rock wool heat preservation material fixing device, the precise installation fixing clamp optimizes the clamping and pressing type fixing mode of the traditional round buckle and the heat preservation nail into the fixing mode of the screw rod and the nut thread connection, so that the rock wool heat preservation material is more firmly fixed, and the operator will not be injured by the heat preservation nail during the construction process, which is safer. In short, the precise installation fixing clamp of the utility model is ingenious in design, reasonable in structure, simple in operation, convenient to disassemble and assemble, and greatly improves the construction efficiency of the construction site.
