Abstract

The utility model relates to a foam concrete roof cast-in-place slab which is sequentially provided with a base layer, a slope finding layer, a leveling layer, a waterproof layer and a surface layer. The base layer is a cast-in-place reinforced concrete roof panel; the slope finding layer is a gentle slope stacked by a layer of foam concrete; the leveling layer is a layer of cast fine aggregate concrete; the waterproof layer is a layer of laid waterproof coiled material; and the surface layer is a fine aggregate concrete protection layer in which reinforcements are arranged. The foam concrete roof cast-in-place slab has a simple structure and is convenient to construct; the foam concrete is adopted to replace a conventional material to be used as the slope finding layer, so that labor consumption of the leveling layer and an insulating layer in the constructing process is reduced, the utilization rate of the materials is improved, the construction progress is quickened, the working period is shortened, the efficiency is ensured, and the structural dead weight is reduced; and moreover, the foam concrete also can be applied to a floor cast-in-place slab and is used as a slope finding insulating layer for carrying out pumping construction on the multilayer ground and the high-layer ground, so that the construction is simple and convenient, the construction efficiency is high ,and the labor input is low. The foam concrete roof cast-in-place slab can be widely applied to the roof and floor cast-in-place slabs.

Description

The cast-in-place plate of a kind of foam concrete roofing

Technical field

The utility model relates to a kind of roof panel.

Background technology

At present, traditional roof heat insulation, sloping layer all use materials such as heat-insulating granules, extruded sheet, cinder; Floor ground uses materials such as haydite, microlith as looking for slope and ground cushion, but, these traditional material constructing operation inconvenience, manually, the material cost height, and need to mix big water gaging in the cinder, heat-insulating granules use, the later stage waterproof construction is produced very big influence, destroy easily waterproof and cause quality problems such as leak, no matter and haydite, microlith are on-the-spotly to stir or buy, all can cause cost to increase, the wasting manpower and material resources.

The utility model content

The purpose of this utility model provides the cast-in-place plate of a kind of foam concrete roofing, solve the technical problem that traditional sloping layer material construction is inconvenient, cost is high; And solution guarantees the problem of construction quality.

For achieving the above object, the utility model adopts following technical scheme:

The cast-in-place plate of a kind of foam concrete roofing; from bottom to top be basic unit, sloping layer, leveling layer, waterproofing course and surface layer successively; described basic unit is cast-in-place reinforced concrete roof board; described sloping layer is to build the gentle slope that by one deck foam concrete; what described sloping layer was built above is one deck pea gravel concreten leveling layer, and described surface layer is joined the pea gravel concreten topping of reinforcing bar in being.

The gradient of described sloping layer is 1 ﹪～3 ﹪.

Compared with prior art the utlity model has following characteristics and beneficial effect:

The utility model has overcome tradition and has looked for that the construction of sloping insulation layer is inconvenient, influential to the later stage workmanship, efficiency of construction is low, the shortcoming of environment protecting difference, has solved the technical problem that reduces manpower and materials, assurance construction quality and efficient.

The utility model is simple in structure, foam concrete is with blowing agent, cement, flyash, stone flours etc. stir into the polymer of the continuous structure of two covers of organic binder, include even pore, foamed system by foaming machine fully foams blowing agent with mechanical system, and foam evenly mixed with cement paste, pumping system through foaming machine carries out cast-in-place construction or mould molding then, through the formed a kind of novel light heat insulating material that contains a large amount of sealed porositys of natural curing, multifunction building material as a kind of novel uniqueness, replace traditional material as sloping layer with foam concrete, has heat insulation function simultaneously, it is a kind of environmental protection, energy-conservation, cost is low, the novel heat insulation heat-barrier material that performance is good, reduced leveling layer, manpower consumption amount in the insulation layer work progress, improve the utilization rate of material, accelerated construction speed, reduction of erection time, guaranteed efficiency, and alleviate dead load, in addition, foam concrete can be applied to the cast-in-place plate of flooring equally, as looking for sloping insulation layer, to multilayer, pumping construction, easy construction are carried out in high-rise ground, the efficiency of construction height, artificial input amount is few.

The utility model can be widely used in roofing, the cast-in-place plate of flooring.

Description of drawings

The utility model is described in more detail below in conjunction with accompanying drawing.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation that foam concrete is applied to flooring.

Reference numeral: 1-basic unit, 2-sloping layer, 3-leveling layer, 4-waterproofing course, 5-surface layer.

The specific embodiment

Embodiment is referring to shown in Figure 1, the cast-in-place plate of this foam concrete roofing, from bottom to top be basic unit 1, sloping layer 2, leveling layer 3, waterproofing course 4 and surface layer 5 successively, described basic unit is reinforced concrete roof board, described sloping layer 2 is to build the gentle slope that by one deck foam concrete, the gradient is divided into two kinds of situations, and when being designed to not accessible roof, the gradient is 1 ﹪; The gradient is 3 ﹪ when being designed to accessible roof, and what described sloping layer was built above is one deck pea gravel concreten leveling layer 3, and described surface layer 5 is joined the pea gravel concreten topping of reinforcing bar in being.

Referring to shown in Figure 2, foam concrete is applied to the cast-in-place plate of flooring, as the sloping layer material, the cast-in-place plate of flooring is followed successively by basic unit 1 from the bottom up, sloping layer 2 and leveling layer 3, shown in basic unit be the reinforced concrete floor plate, leveling layer is a layer concrete.

Work progress of the present utility model, concrete steps are as follows:

Step 1, before the construction, relevant water, electricity, gas pipeline secretly buries construction and finishes, and all hole concretes teeming are finished.

Step 2 is landed ash, foreign material with the mortar of basic unit and is cleaned out, and acceptance(check), guarantees dustless, the no ponding of basic unit, becomes flexible, the dusting phenomenon.

When step 3, temperature are lower than 5 ℃, forbid to carry out the sloping layer construction, when temperature meets the demands, carry out the construction of foam concrete sloping layer.

Step 4, the foam concrete sloping layer should successively be constructed, and last one deck is carried out floating, guarantees to reach the design grade requirement.

Step 5, foamed concrete material is mobile big, before the moulding, does not take waterproof, rainproof measure.

Step 6 after the moulding of concrete sloping layer, is preserved moisture and is rested 3-7 days, builds one deck pea gravel concreten leveling layer.

Step 7, construction of leveling blanket are finished and are reached after the requirement, re-lay waterproofing materials, as waterproofing course.

Step 8 begins to build surface layer, and surface layer is the pea gravel concreten topping of built-in reinforcing bar, and material flattens after building and finishing, be difficult within 36 hours going up the people, and maintenance 14 days, to reach design strength.
