[0002] During the construction of retro buildings, many feature antique and vintage-inspired elements, such as distinctive facing columns, some of which feature variable-diameter, irregularly shaped pebble facings. Traditionally, facing columns are primarily constructed using mortar masonry. However, traditional construction techniques struggle to maintain the desired curvature and quality of these columns, posing a significant risk of rework. Furthermore, the limited height of each pour significantly impacts on-site construction progress.

[0011] The two ends of the mold barrel are closed to form a sealed cavity, and an inspection hole is opened at the upper end of the mold barrel;

[0012] The slurry is pressurized and injected into the sealed cavity through the grouting pipe. The slurry covers the pebble masonry layer, the embedded steel bars and the structural core column to consolidate and form the pebble facing masonry layer.

[0013] Furthermore, the grouting pipe is arranged vertically, and the lower end of the grouting pipe extends to the outside of the lower end of the mold cylinder.

[0025] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] See Figures 6 to 8 The special-shaped pebble-faced column of the present invention includes a structural core column 1 and a pebble-faced masonry layer. The pebble-faced masonry layer is coated on the structural core column 1. The pebble-faced masonry layer includes a pebble masonry layer and grout coated on the pebble masonry layer. The grout encapsulates the pebbles in the pebble masonry layer.

[0028] In this embodiment, the pebble facing masonry course is in a truncated cone shape, and the top end of the structural core column extends above the pebble facing masonry course.

[0029] Continue to refer to Figures 1 to 8 As shown, the present invention provides a construction method for special-shaped pebble facing columns, comprising the following steps:

[0030] S1: Casting structural core column 1.

[0031] In this embodiment, the structural core is cylindrical.

[0032] Measure and position the lines, locating the structural core columns and the edge and control lines of the pebble facing masonry. Clean the basement according to the edge and control lines. Construct the structural core columns according to the design drawings.

[0033] S2: multiple embedded steel bars 11 are implanted outside the structural core column 1.

[0034] After the concrete of the structural core column reaches a certain strength, the column body of the structural core column is anchored with reinforcement. The diameter and depth are sufficient for anchoring the pebble masonry layer, and the exposed length is determined according to the thickness of the pebble facing masonry layer.

[0035] S3: Install the grouting pipe 3 on the outside of the structural core column 1, and the grouting pipe 3 is arranged vertically.

[0036] The grouting pipe 3 is arranged vertically, and the lower end of the grouting pipe 3 extends to the outer side of the lower end of the mold cylinder 4.

[0037] Install and fix the grouting pipe close to the cylindrical surface of the structural core column.

[0038] S4: A mold cylinder 4 is sleeved on the outer sides of the structural core column 1 , the embedded rebar 11 and the grouting pipe 3 , so that an accommodating space is formed between the mold cylinder 4 and the structural core column 1 .

[0039] In this embodiment, the mold barrel is in the shape of a truncated cone, and the diameter of the mold barrel 4 gradually decreases from bottom to top.

[0040] The lower end of the mold barrel 4 is sealed with the ground. In this embodiment, the mold barrel includes at least two curved templates. The outer edges of the curved templates form flange plates. The flange plates of the multiple curved templates are detachably connected together by bolts.

[0041] Customized mold barrels are installed according to the facing column edges and control lines. The mold barrels are connected with bolts, and the gap between the lower end of the mold barrel and the ground is sealed with mortar. Sealant pads are used to seal the multiple curved templates of the mold barrel to prevent leakage that may affect the final appearance quality.

[0042] S5: pebble layers 5 are formed in the accommodating space.

[0043] S6: Both ends of the mold cylinder 4 are closed to form a sealed cavity, and an inspection hole is opened at the upper end of the mold cylinder 4.

[0044] The upper end of the mold barrel 4 is sealed and connected to the structural core column 1 through a sealing ring plate 41 .

[0045] The structural core column 1 is embedded in the inner ring hole of the blocking ring plate 41. The outer edge of the blocking ring plate 41 is sealed and connected to the upper end surface of the mold barrel 4.

[0046] The upper end of the mold barrel 4 is formed with a locking flange. A blocking ring plate 41 is attached to the locking flange. The blocking ring plate 41 is bolted to the locking flange.

[0047] S7: The slurry is pressurized and injected into the sealed cavity through the grouting pipe 3. The slurry covers the pebble masonry layer 5, the embedded steel bars 11 and the structural core column 1 to solidify and form a pebble facing masonry layer.

[0048] When the slurry reaches the demoulding strength, the formwork is removed, and the column pebble surface and joints are cleaned in time. The decorative column is wrapped with plastic film and maintained for 7 days.

[0049] The construction method of the special-shaped pebble facing column of the present invention is to plant reinforcement around the structural core column before construction, and the exposed length is determined according to the thickness of the facing, which effectively improves the integrity of the structural core column and the pebble facing masonry layer.

[0050] The construction method of the special-shaped pebble facing column of the present invention comprises the following steps: the grouting pipe is fixed closely to the core column surface of the structure; grouting holes are arranged every 500 mm along the length direction of the grouting pipe, thereby greatly improving the grouting efficiency.

[0051] The construction method of the special-shaped pebble facing column of the present invention can meet the factory processing progress requirements by setting a standardized mold barrel, so as to achieve special structural requirements such as the curvature desired in the design drawings.

[0052] The mold barrel is made of steel, which has sufficient rigidity to greatly increase the material turnover rate and effectively play a restraining role with multiple pebbles. It can also withstand the grouting pressure during the grouting process to avoid target deformation.

[0053] The construction method of the special-shaped pebble facing column of the present invention can ensure the density of the gaps between the pebbles by pressurized grouting, greatly improve the bonding force between the pebbles, and make the overall effect better.

[0054] Through the inspection hole set on the sealing ring plate (which can also be used as an exhaust hole), the grouting process can be effectively understood and the completion status of the grouting can be grasped in time.

[0055] The construction method of the special-shaped pebble facing column of the present invention provides a prefabricated mold cylinder, uses the mold cylinder to stack the pebble masonry layer, and forms a sealed cavity for pressurized grouting. It not only effectively solves the difficulty of controlling the surface curvature of the special-shaped facing column of the traditional process and improves the overall quality and appearance of the facing column, but also improves the on-site construction progress and greatly saves the construction period.

[0056] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept.
