The method for constructing the facing concrete comprises the following steps:
step one, construction preparation: determining the size and the number of the templates 1 according to the size of the facing concrete to be constructed; determining the size, the number and the position of the bubble film 2 according to the size and the position of the decorative surface to be set on the concrete with the decorative surface to be constructed; the bubble film 2 is adhered to the corresponding position of the corresponding template 1, and the bubble bodies 2.2 on the bubble film 2 are opposite to the template 1.
The monolithic template 1 provided with the bubble film 2 of the present embodiment has a length of 1830 mm, a thickness of 18 mm, and a height of 915 mm; the correspondingly arranged bubble film 2 is arranged on the template 1 in the middle, and the edge of the bubble film 2 is positioned within the edge of the template 1 and is 50 mm away from the edge of the template 1. In the embodiment, only one formwork 1 is provided with the bubble film 2, namely, only one surface of the concrete to be constructed is a facing 9.
Step two: installing a template 1: and enclosing a plurality of templates 1 according to the size of the facing concrete to be constructed and the position of the facing 9 to form a concrete pouring cavity, and ensuring that the surface of each template 1 provided with the bubble film 2 is opposite to the concrete pouring cavity.
Step three: pouring concrete: continuously and hierarchically pouring concrete into the concrete pouring cavity in the second step, and performing vibration operation layer by layer; wherein, the vibrating operation is completed by a plurality of vibrating rods; the plurality of vibrating rods keep the same distance with the bubble film 2, and the operation time of each vibrating rod is the same.
In the pouring process, the mature process of 'simultaneous pouring and vibrating, layering and stacking, once reaching the top and gradual progression' is followed. The slump of the concrete and the conveying time of the concrete are strictly controlled to prevent the concrete from generating segregation phenomenon. Pouring the concrete layer by layer; the layered blanking thickness is not more than 500 mm, and the concrete is vibrated layer by layer to ensure the pouring quality of the concrete; the layered pouring must be continuously carried out, and the pouring time interval of the upper layer and the lower layer does not exceed the initial setting time of the concrete. The occurrence of construction cold joints is strictly prohibited. In the concrete pouring and vibrating process, the reinforcing steel bars arranged in the concrete pouring cavity cannot be moved randomly. During vibration, the two ends of the concrete pouring cavity, namely the closest point and the farthest point of concrete flowing are controlled in a key mode. The vibrating rods cannot be directly leaned against the template 1 provided with the bubble film 2, the plurality of vibrating rods and the bubble film 2 should keep the same distance, and the operation time of each vibrating rod at the same position is the same.
Step four: removing the mold and maintaining: and after the poured concrete is solidified, removing the template 1 to carry out spray curing on the solidified concrete to form a finished concrete semi-finished product. The form removal and maintenance are performed in the conventional manner, and this embodiment is not particularly limited.
Step five: construction of a protective agent: and spraying a protective agent on the surface of the finished concrete semi-finished product to form a transparent protective film on the surface of the finished concrete semi-finished product so as to form a finished concrete product. The protective agent adopts the existing finished product, selects the concrete protective agent with excellent permeability, can permeate into the surface of the facing concrete semi-finished product for 1-5 mm, has good consolidation and mechanical properties, and forms a transparent protective film on the surface of the facing concrete semi-finished product. The concrete protective agent is colorless and transparent, and the color and the appearance of the finished concrete semi-finished product are not changed; the semi-finished product of the finished concrete is not easy to be wetted by water after treatment, and can prevent the damages of chloride corrosion, reinforcing steel bar corrosion and the like caused by capillary water absorption, thereby improving the durability of the concrete.
Before the construction of the protective agent, the method also comprises the following defect repairing construction: adopting a water drill to perform slotting operation on the quality defect part of the finished concrete semi-finished product, so that the quality defect part forms a groove with the diameter being the same as that of the 2.2 diameter of the bubble body; the quality defect part comprises a sunken part formed by the inner concave surface of the facing 9 inconsistent with the outer contour surface of the bubble body 2.2, for example, the inner concave body 7 formed by the facing 9 of the facing concrete 8 after the bubble body 2.2 collapses or partially collapses does not meet the standard, and the inner concave body 7 which does not meet the standard is the quality defect part. The rhinestone of the embodiment is directly and preferably the same as the 2.2 diameter of the air bubble body, so that a groove with the diameter of 25 mm can be directly drilled, the groove is similar to the profile surface of the inner concave body 7 which meets the standard, and the repairing construction of the quality defect part is realized. In addition, the related modeling can be manually chiseled by using steel rods to ensure the integrity and consistency of the effect of the veneer 9.
The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may be made by those skilled in the art without departing from the principle of the invention.
