Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an assembly structure of concrete column templates with imitation forest ecological wood grain finishes. Background Art

[0002] In recent years, a variety of finishes for exposed concrete have been developed. Among these, wood-grain and bamboo-grained exposed concrete forms often use conventional plywood as the base formwork, with natural wood-grain or bamboo-grained strips laid on top as the inner lining. These two are connected and secured using nails or adhesives to form a single, integrated wood-grain formwork. For larger walls, using a single, monolithic formwork is too bulky and difficult to manufacture, process, hoist, and install. Multiple forms must be assembled together, which can lead to loose joints and leaks, significantly impacting the quality and appearance of the exposed concrete with a wood-grain finish. However, for independent columns, due to their smaller formwork dimensions, the exposed concrete formwork can be assembled using a single, monolithic process, hoisted into place, and reinforced. The concrete is then cast together with the column. After the exposed concrete formwork is removed, the forest-like wood grain finish can be applied directly to the column surface. Therefore, developing a suitable structure for the monolithic assembly of exposed concrete formwork on columns is crucial. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model proposes an assembly structure of concrete column formwork with imitation forest ecological wood grain finish, which greatly facilitates the overall assembly construction of the column wood grain plain concrete formwork. After removing the wood grain finish concrete formwork, the imitation forest ecological wood grain finish can be directly formed on the surface of the column.

[0004] In order to realize the above technical scheme, the utility model provides an assembly structure of forest ecological wood grain facing concrete column formwork, including: an outer formwork frame, the front inner side surface and the rear inner side surface of the outer formwork frame are both installed with wood grain facing concrete formwork modules, and after the three-section tension bolts pass through the wood grain facing concrete formwork module and the outer formwork frame, the wood grain facing concrete formwork module is locked to the inner side surface of the outer formwork frame, the three-section tension bolts are locked with the outer formwork frame at the joint by a butterfly buckle, and the three-section tension bolts are locked with the wood grain facing concrete formwork module at the joint by a sleeve and a plastic plug, and the left and right ends of the two wood grain facing concrete formwork modules are respectively closed by lining plates.

[0005] In the above technical solution, in actual operation, the outer formwork is first designed according to the requirements of the column casting. Then, a single prefabricated wood-grain finish concrete formwork module is installed on the front inner side and rear inner side of the outer formwork using hoisting equipment or manual assembly methods. Then, three-section tension bolts are respectively passed through the wood-grain finish concrete formwork module and the outer formwork. The three-section tension bolts are locked at the joints with the steel pipe column hoop using butterfly clips. The three-section tension bolts are locked at the joints with the wood-grain finish concrete formwork module using sleeves and plastic plugs. Then, the left and right ends of the two wood-grain finish concrete formwork modules are respectively closed with lining plates to construct a concrete casting space. After the concrete is poured and solidified, the outer formwork and the wood-grain finish concrete formwork module are removed, and the imitation forest ecological wood grain can be produced on the surface of the concrete column, which is very convenient to construct.

[0006] Preferably, the outer mold frame is formed into a "well" shape by splicing and fixing a plurality of steel pipe column hoops through straight-through high-strength bolts to facilitate rapid splicing and adjustment and fixation of the outer mold frame.

[0007] Preferably, the wood-grain finish concrete formwork module comprises a plywood outer formwork, a forest-like ecological wood-grain solid wood inner formwork, separating strips, and square steel backing ribs. The forest-like ecological wood-grain solid wood inner formwork is fixed to the front side of the plywood outer formwork, multiple separating strips are installed in parallel and at intervals on the forest-like ecological wood-grain solid wood inner formwork, and multiple square steel backing ribs are installed in parallel and at intervals on the back side of the plywood outer formwork. The wood-grain finish concrete formwork module can be prefabricated and assembled. The forest-like ecological wood-grain solid wood inner formwork is fixed to the front side of the plywood outer formwork by nailing, and the square steel backing ribs are fixed to the back side of the plywood outer formwork. During actual installation, the prefabricated wood-grain finish concrete formwork module can be hoisted and installed as a whole on the inner side of the outer formwork frame, greatly reducing the difficulty of on-site construction.

[0008] Preferably, the imitation forest ecological wood grain solid wood board inner mold is assembled from multiple solid wood casting inner mold units, each of which can be cast with ecological wood grain finishing concrete. The imitation forest ecological wood grain in each solid wood casting inner mold unit can be the same or different, thereby providing a richer finishing pattern.

[0009] Preferably, a V-shaped chamfered seam is reserved at the top joint between adjacent solid wood casting inner mold units to prevent the solid wood casting inner mold units from warping and deformation after being spliced.

[0010] The beneficial effect of the forest-like ecological wood grain finish concrete column formwork assembly structure provided by the utility model is that: the forest-like ecological wood grain finish concrete column formwork assembly structure is rationally designed and easy to construct. After the wood grain finish concrete formwork is removed, the forest-like ecological wood grain finish can be directly formed on the column surface. In actual work, it is only necessary to design the outer formwork frame according to the requirements of the column casting, and then use hoisting equipment or manual assembly methods to install the single prefabricated wood grain finish concrete formwork module on the front inner side and the rear inner side of the outer formwork frame, and then pass through the wood grain finish concrete formwork module and the outer formwork frame respectively through three-section tension bolts, use butterfly buckles to lock the three-section tension bolts with the steel pipe column hoop at the joint, use sleeves and plastic plugs to lock the three-section tension bolts with the wood grain finish concrete formwork module at the joint, and then close the left and right ends of the two wood grain finish concrete formwork modules with lining plates to construct a concrete pouring space, which greatly facilitates the overall assembly construction of the column wood grain plain concrete formwork. After the concrete is poured and solidified, the outer formwork frame and the wood grain facing concrete formwork module are removed, and the imitation forest ecological wood grain can be produced on the surface of the concrete column, which is very convenient to construct.
