Description

Ground leveling anti-cracking structure

Technical Field

The utility model relates to a building technical field, a ground structure specifically says so.

Background

In modern home decoration, floors are often paved on the ground, and the ground needs to be processed in advance in order to ensure the pavement of the floors; in particular, in the case of geothermal heating, geothermal pipes below the ground are often re-paved; because the floor is higher to the precision error on ground, want to guarantee that whole precision can use 3 m's guiding rule to make level during the bricklayer's construction, once survive and compromise whole, the operation is very difficult, simultaneously because the middle stage of whole engineering is handled to the bricklayer construction stage, from the bricklayer survival to the floor spread and paste, middle cycle is about 40-60 days, at this time segment, the ground of bricklayer construction often can appear the phenomenon such as fracture, bulge, during later stage floor installation, because the fracture, bulge is more, cause roughness etc. to be not conform to the floor and spread and paste the requirement, need polish the processing to ground, perhaps fill up the gap with gypsum, the higher construction that can increase self-leveling after handling the completion of requirement. However, the above operation method still cannot ensure the change of the surface layer of the ground caused by the temperature change, and the fundamental reason is that the ground and the wall surface have no adjustment allowance directly, and when the temperature is higher, the defects of cracking, bulging and the like are caused due to the difference of deformation.

Disclosure of Invention

In order to solve the above technical problem, the utility model aims at providing a ground structure, concrete technical scheme is as follows:

a ground leveling anti-cracking structure is characterized in that a foundation cement mortar layer is arranged on a floor slab, a reflecting film is arranged on the foundation cement mortar layer, a pipeline layer is arranged on the reflecting film, a geothermal pipeline is spirally arranged in the pipeline layer, buffer sheets are arranged between the peripheral edge of the pipeline layer and a wall surface, metal buffer keels are uniformly arranged above the pipeline layer in parallel, a ground surface layer is arranged between the metal buffer keels, and the height of the ground surface layer is consistent with that of the metal buffer keels; the peripheral edge of the ground surface layer is consistent with the peripheral edge of the pipeline layer and is abutted with the buffer sheet.

The lower part of the section of the metal buffer keel is triangular, and the upper part of the section of the metal buffer keel is symmetrical L-shaped.

The buffer sheet is one of a strip-shaped benzene board or a strip-shaped foam board.

The utility model has the advantages that: owing to set up the buffer block, consequently, can overcome the bulge defect that causes because ground thermal expansion, and metal buffering fossil fragments are triangle-shaped because the cross-section lower part, can cushion the ground top layer between fossil fragments, and owing to highly setting for metal buffering fossil fragments in advance, consequently, when the construction of ground top layer, use metal buffering fossil fragments's height as the benchmark, adopt the scraper blade overlap joint between two adjacent metal buffering fossil fragments, directly strike off exceed high cement mortar can, consequently, construction convenience, the precision is guaranteed.

Detailed Description

The utility model is described in detail with the following drawings, as shown in the figures, a foundation cement mortar layer 3 and a wall body 2 are arranged on a floor slab ground 1, a reflective film 4 of a paving geothermal pipe is arranged on the foundation cement mortar layer, a pipeline layer 6 is arranged on the reflective film, a geothermal pipeline 7 is spirally arranged in the pipeline layer 6, buffer sheets 5 are arranged between the peripheral edge of the pipeline layer and the wall surface, metal buffer keels 9 are uniformly and parallelly arranged above the pipeline layer 6, and when the metal buffer keels 9 are arranged, an infrared measuring device can be adopted to ensure that the height of the upper surface of the metal buffer keels 9 is consistent with that set in advance, a ground surface layer 8 is arranged between the metal buffer keels, and the height of the ground surface layer 8 is consistent with that of the metal buffer keels; the peripheral edge of the surface layer 8 coincides with the peripheral edge of the duct layer 6, and both are abutted against the cushion sheet 5.

The lower part of the cross section of the metal buffer keel is a triangle 91, and the upper part of the cross section of the metal buffer keel is a symmetrical L-shaped 92.

The utility model discloses once only make level the whole and fall into the segmentation subregion and make level, fill the construction reference point simultaneously, the operation of being convenient for is under construction like this, better control accuracy simultaneously.

The height reference point is based on the survival height of the tile work ground, metal buffer keels are used as ground reinforcing bars on the ground at intervals of 2m, and the height reference point is calculated by 2m when the height of the metal buffer keels is less than 2 m.

And (3) leveling the subsection area, namely leveling by taking the width as the standard, and because the metal buffer keel is additionally arranged, the adjacent areas are positioned on the same plane when the next area is leveled again.

The construction scheme is as follows: before leveling the ground, a bricklayer cleans the original ground, uses cement to make slurry (or uses waterproof slurry to replace the waterproof slurry), pours the prepared slurry on the original ground, uses a rolling brush or a broom to sweep the slurry to form a basic cement mortar layer, the method aims to increase the moisture-keeping effect on the basic cement mortar layer, can better maintain a base layer, marks the elevation of the surviving ground, cuts a polystyrene board or a foam board with the thickness of 2cm into edgings before the construction of the base layer of the ground, fixes the ground around a wall surface by taking the ground as the standard, slightly deforms the ground due to the influence of temperature, increases the telescopic space, plays a good control role in bulging the ground, arranges a metal buffer keel by taking the survival point as the standard and taking each interval of 2m as the standard (less than 2m is calculated by 2 m), fixes the metal buffer keel by using the cement mortar, the height is the same as the survival standard line, the mortar material in the fixed point rib filling area is filled during construction, and meanwhile, a special 2m guiding rule is used for leveling, so that the integral flatness and precision are ensured.

After the construction is finished, the hardness of the ground can be guaranteed to be not less than 3 days after treading, and the ground is watered to preserve moisture.

After the ground is moisturized, the ground base layer is covered with a special mulching film, and the position close to the wall surface is exposed by 2cm, so that the moisture can be slowly volatilized.

Experiments show that the cement slurry before construction has the advantages of closed moisturizing of the original ground, moisturizing of the special mulching film after survival has obvious prevention effect on cracking and bulging, and obvious control effect of keel reinforcing on ground precision.
