Description

Technical Field

[0001] The utility model relates to the technical field of building formwork, in particular to a building construction formwork with a compressive structure. Background Art

[0002] A building formwork is a temporary support structure, which is made according to the design requirements, so that the concrete structure and components are formed at the specified positions and geometric dimensions, maintain their correct positions, and bear the self-weight of the building formwork and the external loads acting on it. The purpose of carrying out formwork engineering is to ensure the quality and construction safety of concrete projects, accelerate the construction progress and reduce the project cost. A building formwork is a formwork and support for concrete pouring and forming, and can be divided into building formwork, building plywood, film-covered board, multi-layer board, double-sided glued board, double-sided film-covered building formwork, etc. according to the nature of the materials. Building formwork can be divided into in-situ concrete formwork, pre-assembled formwork, large formwork, leap-up formwork, etc. according to the construction process conditions.

[0003] Some existing concrete column formworks usually use two sets of semi-circular formworks for splicing, and only use fixed bolts to fix the two sets of formworks. However, when pouring into the formwork, the inner wall of the formwork will bear a large lateral force, which easily causes the fixed bolts on the side of the formwork to deform to a certain extent. Not only is it difficult to disassemble the formwork subsequently, but also the side of the formwork for installing the fixed bolts is equally prone to force deformation. The formwork may need to be frequently repaired or replaced due to local damage, resulting in construction delays and cost increases. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the disadvantages that some existing concrete column formworks usually use two sets of semi-circular formworks for splicing, and only use fixed bolts to fix the two sets of formworks. However, when pouring into the formwork, the inner wall of the formwork will bear a large lateral force, which easily causes the fixed bolts on the side of the formwork to deform to a certain extent. Not only is it difficult to disassemble the formwork subsequently, but also the side of the formwork for installing the fixed bolts is equally prone to force deformation. The formwork may need to be frequently repaired or replaced due to local damage, resulting in construction delays and cost increases, and to provide a building construction formwork with a compressive structure.

[0005] The purpose of the utility model is achieved by the following technical solutions: a building construction formwork with a compressive structure, including a base, on which a corresponding first formwork and a second formwork are installed. The first formwork and the second formwork are both semi-circularly arranged. Sealing plates and first abutting plates are respectively installed at both ends of the first formwork. Second abutting plates are installed at both ends of the second formwork. A sealing groove adapted to the second abutting plate is provided on the sealing plate. The first abutting plate and the second abutting plate are in contact with each other. A C-shaped fixing plate for clamping the first abutting plate and the second abutting plate is installed on one side of the first abutting plate;

[0006] The sealing plate, the first abutting plate, the second abutting plate and the C-shaped fixing plate are all provided with first threaded holes. A first fastening bolt is threadedly installed on the first threaded hole. The first fastening bolt penetrates through the first threaded hole and is threadedly installed with a fastening nut. By providing the sealing groove on the sealing plate at one end of the first template and the second abutting plate at one end of the second template, it is convenient to dock and install the sides of the first template and the second template. At the same time, by providing the sealing plate and the C-shaped fixing plate, they can cooperate with the first fastening bolt, the first threaded hole and the fastening nut to fix the two sides of the first template and the second template. The sealing plate and the C-shaped fixing plate can effectively evenly distribute the pressure generated on the sides of the first template and the second template during pouring, improve the compressive capacity of the sides of the first template and the second template, thereby preventing the first fastening bolt from being deformed due to excessive stress during pouring, thus ensuring the service life of the sides of the first template and the second template and the first fastening bolt, and effectively reducing costs.

[0007] A further technical solution is that rotatable support plates are installed on the outer sides of the first template and the second template. A telescopic plate is installed at the lower part of the support plate. A support groove is provided on the base. One end of the telescopic plate away from the support plate extends into the support groove and is fixed to the support groove by a second fastening bolt;

[0008] Through holes are provided on both the support plate and the telescopic plate.

[0009] A further technical solution is that storage grooves corresponding to the support plates are provided on both the first template and the second template. A rotatable rotating shaft is installed in the storage groove. One end of the support plate is connected to the rotating shaft;

[0010] Two groups of through holes are provided on the telescopic plate. Second threaded holes corresponding to the third fastening bolts are provided on the inner wall of the storage groove. The third fastening bolt can pass through the through hole and be threadedly connected to the second threaded hole. By providing the storage groove, the support plate can be stored in the storage groove when disassembling and transporting the first template or the second template, thereby facilitating the disassembly and transportation of the first template and the second template. After the telescopic plate is retracted into the support plate, the third fastening bolt passes through the through holes on the support plate and the telescopic plate and is threadedly connected to the second threaded hole on the inner wall of the storage groove, thereby realizing the storage and fixation of the support plate and the telescopic plate in the storage groove, and ensuring the stability of the support plate stored in the storage groove.

[0011] A further technical solution is that third fastening bolts are installed on the outer surfaces of the first template and the second template. The third fastening bolts include multiple groups of transverse ribs and longitudinal ribs arranged at equal distances, and the transverse ribs and the longitudinal ribs are perpendicular to each other. By providing the transverse ribs and longitudinal ribs on the outer surfaces of the first template and the second template, the overall strength of the first template and the second template can be improved, thereby reducing the deformation amount of the first template and the second template and effectively extending the service life of the first template and the second template.

[0012] A further technical solution is that the sealing groove is arranged in a U shape, and the inner wall of the sealing groove is slidably connected to the outer wall of the second abutting plate. By arranging the inner wall of the U-shaped sealing groove to be slidably connected to the outer wall of the second abutting plate, it is convenient for the second abutting plate to be installed into the sealing groove, improving the installation convenience. At the same time, the U-shaped sealing groove and the second abutting plate cooperate to effectively improve the overall strength of the sides of the first template and the second template, thereby reducing the deformation of the sides of the first template and the second template.
