2. The foaming cement layer and the foaming gypsum are both made of foaming materials, so that the foaming cement layer is large in porosity and good in heat preservation effect; compared with a foamed cement layer and a foamed gypsum layer, the self-leveling gypsum layer has better rigidity and better temperature thermal conductivity, so that the self-leveling gypsum layer has corresponding support strength and better thermal conductivity, and the high-efficiency utilization of heat in the heating pipe is facilitated; and the self-leveling gypsum layer has better leveling effect and is not easy to crack under the influence of temperature.
3. Because the flexibility of foaming gypsum is better than the non-foaming material, consequently use foaming gypsum to fill logical heating coil clearance, can play the cushioning effect to logical heating coil expend with heat and contract with cold when leading to, reduce logical heating coil spalling risk, also can reduce foaming gypsum layer fracture risk.
4. This application building structure can be under guaranteeing the compressive strength condition, and is thinner, uses when indoor, can increase indoor volume, for example use on the ground, and multiplicable floor height, the comfort level of living is better.

Detailed Description
In order to clearly explain the technical features of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited by the specific embodiments disclosed below.
As shown in fig. 1-2, the thermal insulation building structure comprises a foaming cement layer 1, a warming layer 2 and a self-leveling gypsum layer 3 which are sequentially arranged; it includes the heating pipe 21 that leads to that is the clearance setting to lead to the warm layer, it has foaming gypsum 22 to fill at least in the clearance of leading to heating pipe 21 to the upper and lower face that can make foaming gypsum laminates foaming cement layer and self-leveling gypsum layer respectively.
Assuming that the application scene is indoor ground, the preparation method of the thermal insulation building structure comprises the following steps:
s1: paving a foamed cement layer with the thickness of 3-4 cm;
s2: after the upper strength of the foamed cement layer is achieved, laying heating pipes, wherein the time for naturally airing the upper strength needs about 2-3 days;

And a decorative surface layer can be laid on the gypsum self-leveling layer according to the use requirement, and the decorative surface layer can be a floor, a ceramic tile or a carpet.
In one specific embodiment, the building structure of the present application is: the self-leveling gypsum pipe comprises a foaming cement layer (3cm), a heating layer (the gap between heating pipes is 20cm, foaming gypsum is filled in the gap), and a self-leveling gypsum layer (1 cm).
The traditional building structure comprises foamed cement (3-4cm), a ground heating pipe (2 cm; 20-30cm), a steel wire mesh sheet (5 cm multiplied by 5cm) and a fine stone concrete layer (4-5 cm).
1. Strength determination by test block experiment
Referring to an L17ZJ301 atlas, a standard test block with compressive strength is made on a construction site, a press is used for testing compression resistance, and the strength value displayed by a resistance testing machine until the test block is damaged is C15, which is equivalent to the strength of a traditional structure, but the structure of the application can be thinner, and is beneficial to increasing the indoor floor height. If the degree of bonding between the layers is not sufficiently good, the layers may become detached or dislocated under compressive forces.
2. Flatness determination by rod experiment
After the site operation, utilize to lean on the pole to measure the multiple spot and lean on the pole distance, ground is to the distance of leaning on the pole promptly, and this application all accords with the requirement after measuring.
3. Test of ground cracking degree
(1) In summer with the indoor temperature of 30-35 ℃, after 1 week of field construction, human eyes observe cracks on the construction ground, a few fine lines appear in the traditional structure, the building structure basically has no cracks, after 2 months, the crack increase phenomenon on the construction ground is observed, and the fine lines increase phenomenon appears in the traditional structure;
(2) in winter with indoor temperature of 8-15 ℃, after 1 week of field construction, the construction ground cracks are observed by human eyes, the building structure basically has no cracks, a few fine lines can appear in the traditional structure, after 2 months, the crack increase phenomenon does not occur in the observation construction ground, and the fine lines increase phenomenon can occur in the traditional structure. After the building is heated for 1-2 months in winter, no crack phenomenon can be observed on the surface of the building structure.
4. Indoor humidity experiment
After construction for 2 months, recording the daily humidity in the same closed room through a humidity sensor, wherein the variation of the humidity in the heat-insulating building structure is +/-5% rh within 1 month; the variation of humidity in the conventional structure was ± 10% rh within 1 month. The reasons for this are: the application foaming gypsum adopts the desulfurization gypsum waste material, and it has certain respiratory, can release certain steam in too dry air, can absorb partial steam in too moist environment, plays the effect of little humidity in the regulation room. Traditional gypsum directly utilizes gypsum ore, and the porosity is relatively little, leads to the regulating effect to be some poorly.
According to the heat-insulating building structure, the foaming cement layer and the foaming material filled in the heating pipe are both foaming materials, both the foaming materials have certain porosity and high bonding strength; the foaming gypsum layer and the self-leveling gypsum layer are both made of gypsum materials, and the combination degree of the two layers is higher, so that the integral combination strength of the building structure is higher. The foaming cement layer and the foaming gypsum are both made of foaming materials, so that the foaming cement layer is large in porosity and good in heat preservation effect; compared with a foamed cement layer and a foamed gypsum layer, the self-leveling gypsum layer has better rigidity and better temperature thermal conductivity, so that the self-leveling gypsum layer has corresponding support strength and better thermal conductivity, and the high-efficiency utilization of heat in the heating pipe is facilitated; and the leveling effect of the self-leveling gypsum layer is also better, and the layer is not easy to crack under the influence of temperature. Because the flexibility of foaming gypsum is better than the non-foaming material, consequently use foaming gypsum to fill logical heating coil clearance, can play the cushioning effect to logical heating coil expend with heat and contract with cold when leading to, reduce logical heating coil spalling risk, also can reduce foaming gypsum layer fracture risk.
In conclusion, the building construction has the advantages of long service life, low construction cost and high heat utilization rate.
