Description

Technical Field

[0001] This utility model relates to formwork for cast-in-place concrete construction, specifically to a structural column formwork installation structure. Background Technology

[0002] Structural columns are key components in building structures that enhance overall integrity and seismic performance, especially in brick-concrete structures and frame-infilled walls. Construction of structural columns requires formwork erection before concrete pouring. Structural columns come in various shapes, such as L-shaped, T-shaped, and cross-shaped. Traditional molds use rigid connections, and for non-right-angle irregular-shaped structural columns, custom-made molds are necessary. This results in poor mold versatility, low reuse rates, high construction costs, and low construction efficiency. Utility Model Content

[0003] This utility model discloses a structural column template installation structure, which can flexibly adjust the angle to match the shape of the structural column, and is convenient and quick to assemble and disassemble, and can be reused multiple times.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A structural column formwork installation structure includes a first masonry wall surface, a second masonry wall surface, a first external corner formwork, a second external corner formwork, a first internal corner formwork, a second internal corner formwork, a first external corner steel back rib, a second external corner steel back rib, a first internal corner steel back rib, a second internal corner steel back rib, and tie rods. The first external corner formwork and the second external corner formwork are hinged together by hinges, and the first internal corner formwork and the second internal corner formwork are hinged together by hinges. The first masonry wall surface and the second masonry wall surface form an internal corner. The first internal corner formwork and the second internal corner formwork are positioned at the internal corner formed by the first masonry wall surface and the second masonry wall surface, such that the first internal corner formwork is flush with the first masonry wall surface, and the second internal corner formwork is flush with the second masonry wall surface. The first external corner formwork is flush with the other side of the first masonry wall surface, and the second external corner formwork is flush with the other side of the second masonry wall surface. The wall surface, the first external corner template, and the second external corner template together enclose the area for casting the structural column. A first external corner steel back rib is installed on the outside of the first external corner template, a second external corner steel back rib is installed on the outside of the second external corner template, a first internal corner steel back rib is installed on the outside of the first internal corner template, and a second internal corner steel back rib is installed on the outside of the second internal corner template. A pair of tie rods are sequentially passed through the first internal corner steel back rib, the first internal corner template, the first masonry wall surface, the first external corner template, and the first external corner steel back rib, with nuts installed at both ends of the tie rods. Another pair of tie rods are sequentially passed through the second internal corner steel back rib, the second internal corner template, the second masonry wall surface, the second external corner template, and the second external corner steel back rib, with nuts installed at both ends of the tie rods. Sealing strips are installed at the hinge joints of the first and second external corner templates, and sealing strips are installed at the hinge joints of the first and second internal corner templates.

[0005] Furthermore, the first external corner template, the second external corner template, the first internal corner template, and the second internal corner template are all made of aluminum, and bolt holes are reserved on each template.

[0006] Furthermore, a tie rod is provided on the outer side of the first external angle steel back rib. One end of the tie rod is welded to the first external angle steel back rib, and the other end of the tie rod is passed through the second external angle steel back rib and fixed with a nut.

[0007] This utility model uses a hinged connection to form external and internal corner templates, which can flexibly adjust the included angle of the template to match its height according to the different angles formed by the polygonal structural column, without the need for additional custom-made templates, thus improving the versatility of the template. During the installation of the template, it is attached to the masonry wall surface and clamped and fixed with steel back ribs, tie rods and nuts, making disassembly and assembly very convenient and allowing for multiple reuses.

[0010] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0011] This embodiment discloses a structural column formwork installation structure, such as... Figure 1 As shown, the structure mainly includes a first masonry wall surface 5, a second masonry wall surface 6, a first external corner template 1, a second external corner template 2, a first internal corner template 3, a second internal corner template 4, a first external corner steel back rib 10, a second external corner steel back rib 11, a first internal corner steel back rib 12, a second internal corner steel back rib 13, and tie rods 8. One end of the first masonry wall surface 5 connects with one end of the second masonry wall surface 6, forming an internal corner. The outer area of ​​the connection point is the construction area for the structural column, which needs to be enclosed by templates to create a space matching the shape of the structural column.

[0012] To accommodate different angles of polygonal structural columns, in this embodiment, the two templates forming the included angle are connected by a hinge, that is: Figure 1One end of the first external corner template 1 is hinged to one end of the second external corner template 2, and one end of the first internal corner template 3 is hinged to one end of the second internal corner template 4. Figure 1 The hinge is omitted from the description; the two templates connected by the hinge can rotate freely to adjust the angle. In this embodiment, the first external corner template 1, the second external corner template 2, the first internal corner template 3, and the second internal corner template 4 are all made of aluminum, and bolt holes are pre-drilled on each template.

Figure 1 As shown, the first internal corner template 3 and the second internal corner template 4 are placed at the internal corner formed by the first masonry wall surface 5 and the second masonry wall surface 6, with the first internal corner template 3 fitting against the first masonry wall surface 5 and the second internal corner template 4 fitting against the second masonry wall surface 6. A sealing strip 7 is installed at the hinge of the first internal corner template 3 and the second internal corner template 4 to prevent grout leakage during the pouring of the structural column. The first external corner template 1 and the second external corner template 2 are placed on the side away from the formed internal corner, with the first external corner template 1 fitting against the other side of the first masonry wall surface 5 and the second external corner template 2 fitting against the other side of the second masonry wall surface 6. Similarly, a sealing strip 7 is installed at the hinge of the first external corner template 1 and the second external corner template 2. After enclosure in the above manner, the first masonry wall surface 5, the second masonry wall surface 6, the first external corner template 1, and the second external corner template 2 together enclose the structural column pouring area 14.
