Plug-in large mold built-in cast-in-place external insulation system features
The plug-in large-mold built-in cast-in-place external thermal insulation system uses steel-plastic composite plugs to fix the thermal insulation board. The connection performance is reliable, the service life of the connecting parts is improved, and the “heat bridge†is completely avoided. The steel wire mortar mortar surface is completely eliminated. The form is economical, durable and impact resistant, and the construction process is simple and convenient.
First, the technical characteristics of the plug-in large mold built-in cast-in-place external thermal insulation system
1. Convenient construction. During on-site construction, the installation of the insulation board is carried out simultaneously with the concrete pouring, which saves the construction period and reduces the installation cost of the insulation board.
2. Good thermal performance. The steel-plastic composite plug and its combination kit are used to fix the thermal insulation board, which is resistant to acid and alkali corrosion, and avoids the thermal bridge effect, and has good thermal insulation effect.
3. The quality of the project is easy to guarantee. The thermal insulation board is overlapped by high and low seams, and there is no expansive phenomenon. Through the joint action of the concrete side pressure and the large formwork supporting force, the installation quality of the thermal insulation board is more easily guaranteed.
4. It is safe and reliable to connect with the structure. The unique connection structure and hanging net design make the transmission structure of the veneer layer more reasonable. The number of plugs can be adjusted according to different veneer loads and structural heights, and the structure connection has high safety and reliability.
5. Advanced technology. Solved the technical difficulties of the cast-in-place shear wall exterior wall facing brick project.
Second, the construction application of plug-in large mold built-in cast-in-place external thermal insulation system
The installation of the plug-in large-mode built-in cast-in-situ external wall insulation board is done after the wall reinforcement is tied, and before the mold clamping, it is carried out simultaneously with the installation of other embedded facilities. The construction process is as follows: erect insulation board and large formwork placement platform → pop up the plug position line on the insulation board → insert the plug according to the design position → fixed EPS insulation board → insulation board installation quality acceptance → fixed template → drill through Wall bolt hole → clamping → fix the insulation board to the formwork at the upper part of the formwork or the door and window opening → cast concrete → demoulding → preliminary cleaning of the surface layer of the insulation board → reinforcement with nylon expansion bolts → stuffing through the wall bolt holes and scaffolding Eye → Install wheel pad and long nut → 抻 flat wire mesh, insert open flat pad, tighten long nut → spray or apply interface agent → hang line, paste cake → smear cement mortar → plaster layer cement mortar → curing → Expansion joint and division joint treatment → paste brick.

Smart homes or Smart Household use 'Home Automation' technologies to provide home owners with 'intelligent' feedback and information by monitoring many aspects of a home. For example, a Smart Home's refrigerator may be able to catalogue its contents, suggest menus, recommend healthy alternatives, and order replacements as food is used up. A smart home might even take care of feeding the cat and watering the plants.A smart home, or smart house, is a home that incorporates advanced automation systems to provide the inhabitants with sophisticated monitoring and control over the building's functions. For example a smart home may control lighting, temperature, multi-media, security, window and door operations, as well as many other functions.mostly now offen on securtiy as Smart Locks ,smart electronics etc.
