Description
Technical Field
The utility model relates to an exempt from to tear open metal matrix screen structure mainly is applicable to the little volume concrete structure that requires not high to the surface smoothness.
Background
The concrete template refers to a whole set of construction system of a newly cast concrete forming template and a supporting template, the classification of the templates has various different grading methods, and the templates are divided into a plane template and a curved surface template according to the shapes; the bearing template and the non-bearing template are divided according to the stress condition. In the construction of reinforced concrete members, steel templates and wood templates are mainly used, and although the two templates are widely used, the problems exposed during the use are not avoidable, such as: the wood template can easily deform and rot in a dry and wet repeated environment, and the steel template can also generate corrosion deformation in a wet environment. The wood template and the steel template have higher processing cost and larger weight, the template is troublesome to disassemble, and a large amount of manpower, material resources and time are needed for maintenance and renovation. The adoption of any template structure can ensure the construction quality and reduce the engineering cost, which becomes a great difficulty for design engineers.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: aiming at the existing problems, the disassembly-free metal template net structure is provided and is mainly suitable for a small-volume concrete structure with low requirement on surface flatness. The utility model adopts the technical proposal that:
a disassembly-free metal formwork mesh structure is characterized by comprising a concrete foundation, erection steel bars, a steel bar mesh, an inclined strut structure and geotextile;
the erection steel bars are pre-implanted into the concrete foundation;
the steel bar net pieces are tied on the erection steel bars, the steel bar net pieces are positioned on the inner sides of the erection steel bars, the erection steel bars and the steel bar net pieces form a metal formwork net, geotextile is arranged on the outer sides of the erection steel bars, and the geotextile takes the erection steel bars and the steel bar net pieces as supports and forms a formwork;
the diagonal bracing structure is detachably connected with the erection steel bar.
Furthermore, after the concrete structure to be poured is poured, only the inclined strut structure and the geotextile need to be dismantled, and the exposed erection steel bars are sprayed with concrete; the metal template net and the sprayed concrete are integrated into a whole, and the surface of the concrete structure is mechanically leveled.
Furthermore, the erection steel bars are formed by bundling a plurality of longitudinal and transverse steel bars.
The concrete structure is generally not suitable for being more than 2m in height and not suitable for being more than 3m in width. The inclined strut structure can adopt a steel pipe inclined strut, and if no steel pipe inclined strut is arranged on a construction site, the inclined strut can be replaced by a wood strut.
The technical scheme of the utility model simple structure, construction facility. The forming template adopted during the pouring of the reinforced concrete structure is disposable, after the pouring is finished, only the steel pipe inclined strut and the geotextile need to be removed, the geotextile with lower value is taken as a disposable article, the reinforcing mesh sheet and the erected reinforcing steel bar do not need to be removed and are taken as the reinforcing steel bar of the poured concrete structure, and the reinforcing mesh sheet and the erected reinforcing steel bar are taken into consideration during the strength design of the concrete structure. The utility model discloses reducible construction process, avoid the cost that the template was maintained, was repaired, was kept to reduce construction cost. Meanwhile, the materials adopted by the structure are engineering materials with higher field popularity, and are convenient to purchase and process on site.

Fig. 1 is a schematic diagram of an embodiment of the present invention.
Fig. 2 is a cross-sectional view of the concrete structure 4 according to the embodiment of the present invention.
Fig. 3 is a cross-sectional view of the embodiment of the present invention after the concrete structure 4 is poured and the shotcrete surface is treated.
Detailed Description
Reference is made to the accompanying drawings. The utility model provides a pair of exempt from to tear open metal formwork net structure includes following structure:
(1) in the process of pouring the concrete foundation 1, erecting reinforcing steel bars 2 and pre-implanting the reinforcing steel bars into the concrete foundation 1; the erection steel bar is one of the main supporting structures of the formwork structure, and the diameter of the erection steel bar is not smaller than 26 mm.
(2) Binding the reinforcing mesh sheets 3 with smaller intervals on the erection steel bars 2, wherein the reinforcing mesh sheets 3 are positioned on the inner sides of the erection steel bars 2 and face the concrete structure 4 to be poured, arranging geotextile 5 on the outer sides of the erection steel bars 2, and adapting the sizes and the shapes of the geotextile 5 and the reinforcing mesh sheets 3 to the surface shape of the concrete structure 4 to be poured; the reasonable size of the mesh of the reinforcing mesh can reduce the flow of concrete, and the geotextile can also block the flow.
(3) After the steel pipe inclined strut 6 fixes the erection steel bar 2, pouring of the concrete structure 4 is started;
(4) and (3) after the concrete structure 4 reaches the strength index, removing the steel pipe inclined strut 6 and the geotextile 5, performing shotcrete 7 treatment on the exposed erection steel bar 2 of the concrete structure 4, and mechanically leveling the surface of the concrete structure 4 by the shotcrete 7 treatment. The allowable deviation of the surface flatness of the sprayed concrete before mechanical leveling is 30 mm. After mechanical leveling, the allowable deviation of the flatness of the structure surface is reduced to 10 mm.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art can change, add or replace the above examples within the scope of the present invention.
