Description

Technical Field

[0001] The invention relates to the field of building decoration, in particular to a building facade made of concrete, and specifically to a one-time forming construction method for ultra-wide concrete decorative lines on the building facade. Background Art

[0002] like Figure 1 When concrete is used as the line material for the facade of a high-rise building, it is necessary to ensure that the shape and style of the lines after construction meet the design and visual requirements; at the same time, it must be operable during the construction operation. If it is not operable, on the one hand, workers will not be able to carry out construction or the construction will be difficult, and on the other hand, the construction quality will not meet the requirements, and structural size deviations and concrete quality problems are likely to occur; affecting the overall beauty of the decorative lines and the overall durability of the project.

[0003] At present, the shaping of concrete lines is generally achieved by on-site formwork. However, in fact, for "special-shaped" concrete decorative lines of unconventional sizes such as extra-wide and extra-large, on-site formwork construction is generally more difficult. For example, due to the influence of force, these lines are designed as internal cavities, which makes it impossible to remove the internal formwork, resulting in a certain amount of engineering waste. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned defects and to provide a one-time forming construction method for ultra-wide concrete decorative lines on building facades.

[0005] In order to achieve the above object, the present invention is achieved in the following ways: A one-time forming construction method for ultra-wide concrete decorative lines on building facades at least comprises the steps of making and filling inner molds, supporting outer molds, pouring at one time and removing the outer molds.

[0006] The one-time forming construction method of the ultra-wide concrete decorative lines on the building facade specifically includes: Step 1: Set up the internal and external operating frames: According to the position and size of the concrete decorative lines, design the position and parameter scheme of the internal and external frames, and strictly locate and lay out the lines and set up the frames according to the requirements of the scheme to control the setting accuracy; Step 2, installing the bottom formwork pad and steel bar binding of the concrete decorative line: installing the bottom formwork of the concrete decorative line according to the positioning data of step 1, setting the bottom pad between the bottom formwork and the inner and outer operating frames, and binding and fixing the bottom steel bars of the concrete decorative line in the bottom formwork; Step 3, install the filling inner mold and tie the side reinforcement: set up the side reinforcement of the concrete decorative line, place the filling inner mold between the bottom reinforcement and the side reinforcement according to the positioning data of step 1, and tie the filling inner mold to the bottom reinforcement and the side reinforcement with iron wire; Step 4: Install the side formwork and top reinforcement: Install the top reinforcement of the concrete decorative lines, and use tension bolts to fix the side formwork on both sides; Step 5: Carry out the pouring of fine stone concrete to ensure accurate and full pouring construction effect of each part; complete the pouring construction of concrete decorative lines; Step 6: Remove the outer mold and maintain it.

[0007] Furthermore, in the one-time forming construction method for constructing ultra-wide concrete decorative lines on the facade, the filling inner mold refers to a foam block whose outer surface is wrapped by a plastic film. The length and width of the filling inner mold are determined according to the designed cavity size of the concrete decorative lines; and the filling inner mold is not taken out after the concrete is poured.

[0008] Furthermore, in step 4, when setting the tension bolts, a metal sheet is set at the position where the filling inner mold is passed by the tension bolts, and the metal sheet is used to prevent the filling inner mold from being damaged by the tension bolts to form a gap.

[0009] Furthermore, in step 4, when the outer surface of the concrete decorative line has a slope or a curved surface, the template and the support are slightly bent according to the curved surface to meet the modeling requirements of the outer surface of the concrete decorative line.

[0010] The one-time forming construction method of ultra-wide concrete decorative lines on building facades proposed in the present invention requires common equipment and convenient materials, is easy to construct on site, and is easy for operators to use, which is beneficial to improving work efficiency and saving labor costs for project construction.

[0011] Furthermore, this method fundamentally solves the problem of difficult formwork and casting of hollow concrete structures of building decorative lines, ensures the continuity of concrete line construction, and can adjust foam block parameters according to required sizes, saving materials and labor, and promoting project cost control and progress control; this method only requires internal fixation of foam blocks, and does not require separate setting of formwork wooden blocks and other measures, which improves the operability in concrete line construction and ensures the safety and convenience of personnel in pouring construction.

[0020] Step 5: Carry out the pouring of fine stone concrete to ensure accurate and full pouring construction effect of each part; complete the pouring construction of concrete decorative lines; Step 6: Remove the outer mold and maintain it.

[0021] In the one-time forming construction method for constructing ultra-wide concrete decorative lines on the facade, the filling inner mold refers to a foam block whose outer surface is wrapped with a plastic film.
