Abstract
The utility model relates to a concrete structure, belonging to the technical field of building construction. The concrete structure comprises a bottom concrete layer and an upper concrete layer, wherein the bottom concrete layer is formed by gravels and cement, and the upper surface of the bottom layer concrete is a gravel exposed surface, and the bottom concrete layer is combined with the upper concrete layer through the gravel exposed surface. After the concrete structure is adopted, the quality problem of a building construction joint can be properly solved, so that the concrete structure is very suitable for great wall bodies, concrete foundations with large volume and composite floor slabs.
Description
Technical field
The utility model relates to a kind of concrete structure that forms after the horizontal construction joint processing method that adopts, and belongs to technical field of building construction.
Background technology
Based on the characteristics of cast-in-place concrete structure, structures such as tall and big body of wall, volume of concrete foundation, laminated floor slab need be provided with horizontal construction joint usually, construction in layer, and the place that all kinds of just quality problems in constuction joint place are relatively concentrated.Understand according to the applicant, comprise that at present the concrete structure of prefabricated component is easy to produce various quality problems.
In order to guarantee that horizontal construction joint satisfies the concrete joint requirement, guarantee construction quality, the special construction that needs a kind of effective universal process method to form.
Summary of the invention
The purpose of the utility model is: the problem to above-mentioned prior art exists proposes a kind of concrete structure with enough bond strengths, thereby guarantees the quality of building operations.
In order to reach above purpose, the concrete structure of the utility model comprises bottom concrete and the last layer concrete that is formed by rubble and cement, and the concrete upper surface of said bottom is the rubble exposed surface, and combines with last layer concrete through the rubble exposed surface.
The utility model further improves: the rubble average grain diameter in the said upward layer concrete is less than the concrete rubble average grain diameter of bottom.
After adopting the structure of the utility model, the quality problems at building operations seam place be can properly settle, tall and big body of wall, volume of concrete foundation, laminated floor slab are very suitable for.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
Embodiment one
The concrete structure of present embodiment is as shown in Figure 1, comprises the bottom concrete 3 of phase I formation and the last layer concrete 1 of second stage formation, and the concrete upper surface of bottom is a rubble exposed surface 2, and combines with last layer concrete 1 through rubble exposed surface 2.During preparation, bottom concrete and last layer concrete can adopt the cement of the identical trade mark, but the rubble average grain diameter that goes up in the layer concrete should be less than the concrete rubble average grain diameter of bottom.
The step of concrete preparation is following:
Step 1: preparation phase I bottom concrete---according to different structural forms such as body of wall, laminated floor slab, volume of concrete foundation, the bottom concrete that joints cement, rubble evenly mix.
Step 2: preparation rubble exposed surface---(hand is by hard sense is arranged at concrete surface when treating the bottom concrete initial set; And in the time of pressing down certain vestige); Use pressure-air to add water or high pressure water washing bottom concrete surface; Rubble is exposed, form coarse rubble exposed surface, and cement paste is removed.
Step 3: layer concrete on the preparation second stage---carry out second stage concreting, layer concrete in the formation at the concrete rubble exposed surface of bottom.
Check constuction joint concrete surface roughness afterwards, handle again with pneumatic pick or cutter hair machine, use the water under high pressure clean surface then, drain the water away like defective need, qualified until second stage concreting.
Facts have proved, behind the employing present embodiment, can satisfy the requirement of concreting, guarantee construction qualities such as tall and big body of wall, volume of concrete foundation, laminated floor slab, guarantee carrying out smoothly of follow-up construction.
Except that the foregoing description, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
Claims (2)
1. a concrete structure comprises the bottom concrete and the last layer concrete that are formed by rubble and cement, and it is characterized in that: the concrete upper surface of said bottom is the rubble exposed surface, and combines with last layer concrete through the rubble exposed surface.
2. concrete structure according to claim 1 is characterized in that: the rubble average grain diameter in the said upward layer concrete is less than the concrete rubble average grain diameter of bottom.
