Integral thermal insulation floor slab and construction method

technical field

The invention relates to the field of building structures, in particular to a floor slab integral with heat insulation and bearing structure.

Background technique

On the one hand, in order to prevent the internal temperature of the room from being too low in winter and too high in summer, an insulation layer should be installed on the roof; on the other hand, with the improvement of people's living standards, more and more residents will lay floor heating when decorating houses. In order to reduce heat loss, it is usually necessary to heat-insulate the floor before laying floor heating. Therefore, both the roof and the floor of the house have a need for heat-insulation treatment.

At present, the thermal insulation layer is widely used on the roof. Most of the thermal insulation layer is made by pasting thermal insulation materials on the surface of the structural layer after the structural layer is poured and reaches its age. After summary, the current insulation layer method has the following disadvantages: Need The second construction will delay the construction period; the cost of the insulation layer is expensive; the insulation layer is laid in a large area, which is easy to cause shrinkage and cracking, and the insulation layer will fall off.

The present invention also provides a construction method for an integral thermal insulation floor slab, which is characterized in that it includes the following steps:

1. Support the formwork of the floor slab according to the architectural design drawings, and bind the steel grid;

2. Mix the plastic particles into the concrete mixture and stir them evenly;

3. Pour the concrete mixture mixed with plastic particles in the space between the formwork and the steel grid, and vibrate with a plug-in vibrator or a plate vibrator until the concrete is vibrated and dense, and the plastic particles float on the concrete mix. compound surface;

4. The concrete mixture and the steel grid form a load-bearing structure layer. During the hardening process of the concrete mixture, the cementitious material of the cement mortar is bonded with plastic particles to form an insulation layer, and the load-bearing structure layer and the insulation layer are integrally formed at one time;

5. After the concrete mixture hardens, lay the surface layer.

The present invention has the following beneficial effects: It subverts the construction method of forming a large area of the traditional load-bearing structure layer separately, and then building or pasting the insulation layer on it, and using the formwork to make individual boards first, and then on-site construction, the production is more convenient , the quality is easy to guarantee; the insulation layer and the load-bearing structure layer are poured at the same time, and the construction is simple. The insulation layer is embedded in the load-bearing structure layer and forms a whole with the load-bearing structure layer. Layer, longer life.
