Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a disassembly-free thermal insulation template suitable for a light steel structure. Background Art

[0002] At present, most light steel villas adopt a two-board and one-core structure, that is, OSB or cement board is fixed on both sides of the keel wall composed of light steel keel, and then rock wool board or glass wool is filled in the inner cavity of the light steel keel. Then, the insulation board is first pasted on the OSB of the outer wall, and then the bonding mortar is painted on the outside of the insulation board, and finally, real stone paint or other decorative materials are sprayed. However, this is not only complicated and time-consuming, but also easy to cause OSB or insulation board to fall off if it is not strictly in accordance with the operating process requirements; in addition, the traditional light steel house construction model adopts two boards and one core, which only insulates the exterior wall and ignores the insulation of the interior wall. In summary, the existing light steel villa keel wall still has efficiency problems:

[0003] 1. The process is complicated, labor-intensive and time-consuming; 2. The exterior wall has thermal insulation effect, while the interior wall insulation is relatively general. Utility Model Content

[0004] The main purpose of the utility model is to provide a non-disassembly insulation formwork suitable for light steel structures, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A disassembly-free insulation formwork suitable for light steel structures comprises an outer disassembly-free formwork and an inner disassembly-free formwork, wherein a first hard layer is installed at the front end of the outer disassembly-free formwork, a second hard layer is installed at the rear end of the inner disassembly-free formwork, and a filling device is installed at the corresponding ends of the outer disassembly-free formwork and the inner disassembly-free formwork.

[0007] Preferably, a group of No. 1 card slots are opened at the rear end of the outer non-disassembly template, and a group of No. 2 card slots are opened at the front end of the inner non-disassembly template. The outer non-disassembly template and the inner non-disassembly template are arranged on both sides of the light steel keel frame on the filling device, so that the formed wall realizes internal and external insulation, and the house built in this way will be more energy-saving.

[0008] Preferably, the filling device comprises a light steel keel frame, cast-in-place foam concrete is installed on the outer surface of the light steel keel frame, a group of blocks are installed at the front and rear ends of the cast-in-place foam concrete, and the light steel keel frame is installed between the outer non-dismantling formwork and the inner non-dismantling formwork through the cast-in-place foam concrete. When the foamed light aggregate concrete is cast-in-place in the keel wall on site, the light aggregate will enter the dovetail groove by self-leveling, thereby forming a whole that is integrated with the cast-in-place foam light aggregate concrete, that is, the cast-in-place foam concrete in the filling device, thereby fundamentally solving the problem of easy detachment of the insulation layer.

[0009] Preferably, the first card slot and the second card slot are dovetail slots.

[0010] Preferably, the two groups of card blocks correspond to the first card slot and the second card slot in upper and lower positions respectively.

[0011] Preferably, the outer non-disassembly template and the inner non-disassembly template are made of polystyrene resin raw material, and three shallow grooves are longitudinally opened on the first hard layer.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting the external non-disassembly formwork and the internal non-disassembly formwork on both sides of the light steel keel frame on the filling device, the formed wall can achieve internal and external insulation. The house built in this way will be more energy-efficient. When the foamed lightweight aggregate concrete is cast in the keel wall on site, the lightweight aggregate will enter the dovetail groove by self-leveling, thereby forming a whole with the cast-in-place foam lightweight aggregate concrete, that is, the cast-in-place foam concrete in the filling device, thereby fundamentally solving the problem of easy shedding of the insulation layer. The improved non-disassembly formwork simplifies the construction process and can also be produced on a large scale by mechanization in factories. The hard layer of the produced insulation board is uniform in thickness and tightly bonded. Compared with on-site manual plastering, not only the efficiency is greatly improved, but also the quality is more guaranteed. At the same time, it is faster to install and reduces the amount of labor.

[0014] 2. The hard layer is composed of gypsum, fly ash, cement, reinforcing agent, water and other materials, and is manufactured through mechanization and factory production. The external and internal non-disassembly formwork are made of polystyrene resin, also known as extruded polystyrene insulation board. It is a rigid foam insulation board that is continuously extruded and foamed by a special process. It has an independent closed bubble structure inside. It is an environmentally friendly insulation material with beneficial properties such as low thermal conductivity, high pressure resistance, moisture resistance, airtightness, non-water absorption, light weight, corrosion resistance and long service life.
