Abstract
Description
Technical Field
[0001] This invention relates to the field of formwork technology for buildings, and more particularly to a formwork for column structures in fair-faced buildings. Background Technology
[0002] In construction engineering, fair-faced concrete, with its unique natural texture and decorative effect, is increasingly favored by architects and owners. Fair-faced concrete is a type of concrete that requires no decoration and uses the cast surface as its finish. It is named for its smooth surface and uniform color. It uses high-precision templates, special cement, and graded sand and gravel, and is cast in one go, eliminating the need for plastering, tiling, and other processes. Its core feature is that it preserves the original texture of the concrete, exposing the aggregate texture and fine pores, presenting a simple and natural industrial aesthetic. Construction requires strict control of the mix ratio, vibration, and curing to avoid defects such as honeycomb and pitting. It combines structural and decorative functions, reduces building material consumption, and conforms to environmental protection concepts. It is widely used in building exterior walls, interior walls, and landscape components, such as museums and art galleries. In recent years, it has also entered home design, becoming a high-end decoration choice with a minimalist style, showcasing the beauty of "natural beauty" and the authenticity of architecture. Fair-faced concrete structural templates are high-precision templates used for casting fair-faced concrete and directly determine the final texture of the concrete surface.
[0003] However, the existing equipment has the following shortcomings: When using the existing equipment, the first and second mounting arms are generally welded and fixed structures. Adjustment requires cutting or replacing parts, which is time-consuming and costly. In use, it is difficult to adapt to different sizes of wooden boards, making it difficult for the equipment to quickly and stably install wooden boards of different sizes.
[0004] Therefore, we proposed a template for the column structure of fair-faced buildings, which achieves stepless adjustment through gear and threaded rod transmission, and can be adapted to different sizes without disassembly, thus solving the problems mentioned above. Summary of the Invention
[0005] The purpose of this invention is to solve the problem that the existing technology has the disadvantage that it is difficult to adjust between the first and second mounting arms of the equipment, making it difficult for the equipment to adapt to wooden boards of different sizes. Therefore, this invention proposes a template for the column structure of fair-faced building.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a template for a column structure in a fair-faced building, comprising a steel plate, a wooden board, a first mounting arm, a second mounting arm, bolts, and an adjusting device. The steel plate is fixedly connected to the surface of the wooden board. The first mounting arm is fitted to the surface of the wooden board, and the second mounting arm is fitted to the surface of the wooden board. The first mounting arm 3 and the second mounting arm 4 are both made of alloy steel with cross-sections of 60mm and 80mm, respectively, and are made of Q355 alloy steel, which has strong load-bearing capacity, is not easily deformed, and is generally adapted to the length of the wooden board (2-6m). The first mounting arm and the second mounting arm are connected by bolts. The adjusting device is installed on the surface of the second mounting arm, and the adjusting device includes a threaded rod. The threaded rod is fixedly connected to the side of the first mounting arm, and the second mounting arm has a through hole for the threaded rod to pass through. The threaded rod is clearance-fitted with the through hole. The limiting block is fixedly connected to the end of the threaded rod away from the first mounting arm. A gear is threadedly connected to the surface of the threaded rod, and a rotating tube is fixedly connected to the surface of the gear. A mounting bracket is sleeved and connected at the connection between the rotating tube and the gear. The mounting bracket is fixedly connected to the surface of the second mounting arm, and a connecting block is fixedly connected to the surface of the second mounting arm. A locking block is slidably connected inside the connecting block, and the locking block meshes with the surface of the gear. A sliding rod is fixedly connected to the end of the locking block away from the gear, and a protrusion is fixedly connected to the surface of the connecting block.
[0007] Furthermore, the slide rod is slidably connected inside the protrusion, and a blocking block is fixedly connected to the end of the slide rod away from the locking block. By setting the blocking block, the slide rod can be limited, reducing the possibility that the slide rod may easily detach from the protrusion during use, making it difficult for the slide rod to limit the first spring.
[0008] Furthermore, a first spring is sleeved and connected to the surface of the slide rod.
[0009] Furthermore, one end of the first spring is fixedly connected to the surface of the protrusion, and the other end of the first spring away from the protrusion is fixedly connected to the surface of the locking block. The first spring is provided to facilitate the application of a reset force to the locking block.
[0010] Furthermore, the thread transmission ratio between the gear and the threaded rod is 1:5, and one rotation of the rotating tube allows for a 10mm adjustment of the mounting arm spacing.
[0011] Furthermore, an auxiliary component is fixedly provided on the side of the second mounting arm. The auxiliary component includes a groove and a guide rod. The groove is formed on the side of the first mounting arm, and the guide rod is fixedly connected to the side of the second mounting arm near the first mounting arm. The guide rod is slidably connected inside the groove. By setting the guide rod, the second mounting arm can be limited, reducing the difficulty of the second mounting arm moving smoothly when the equipment is in use.
[0012] Furthermore, a guide block is fixedly connected to the end of the guide rod away from the second mounting arm. The guide block is slidably connected inside the groove, and the fit clearance between the guide block and the groove is 0.1-0.3mm.
[0013] The mounting bracket fixes the position of the gear and the rotating tube to ensure stable transmission; the limit block restricts the maximum movement distance of the threaded rod to reduce the risk of parts detaching due to over-adjustment.
[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows:
[0015] 1. In this invention, by setting an adjustment device, the first and second mounting arms are effectively adjusted, thereby adjusting the distance between them. This reduces the difficulty in adapting to different sizes of wooden boards, which is a common problem in existing equipment where the first and second mounting arms are generally fixedly connected. Compared to traditional fixed-spacing mounting arms, this invention can adapt to wooden boards with a width of 200-500mm, with an adjustment accuracy of ±1mm and an adjustment efficiency increased by 60%. It achieves precise adjustment of the distance between the first and second mounting arms, improving the adaptability of the equipment.
[0016] 2. In this invention, by setting auxiliary components, the first and second mounting arms are effectively moved smoothly, playing a stabilizing role during the adjustment of the first and second mounting arms. This reduces the likelihood of rotation during the movement and adjustment of existing equipment, which can make it difficult to move and adjust the first and second mounting arms smoothly. This auxiliary component ensures that the verticality deviation of the mounting arms during movement is ≤0.5mm / m, significantly reducing the risk of template deformation. The cooperation between the guide rod and the guide block ensures the stability of the mounting arms during movement and improves the stability of the equipment. Attached Figure Description

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0025] Please see Figures 1-5 This invention provides a technical solution: a template for a column structure in a fair-faced building, comprising a steel plate 1, a wooden board 2, a first mounting arm 3, a second mounting arm 4, bolt rods 5, and an adjustment device 6. The steel plate 1 is fixedly connected to the surface of the wooden board 2. The wooden board 2 is a waterproof plywood with a thickness of 18mm, specifically 2440mm in length and 1220mm in width, generally with a moisture content ≤12%, a static bending strength ≥150MPa, and a tough texture with a certain degree of elasticity, allowing it to fit tightly against the steel plate 1. The steel plate 1 is a high-strength cold-rolled steel plate with a thickness of 2-3mm and a surface roughness Ra≤1.6μm. It is generally connected to the wooden board 2 by countersunk bolts with a bolt spacing of 300mm. The first mounting arm 3 is fitted to the surface of the wooden board 2, and the second mounting arm 4 is fitted to the surface of the wooden board 2. The first mounting arm 3 and the second mounting arm 4 are connected by bolt rods 5, which are M16×150mm high-strength bolts with a strength of 8.8, and are installed every 500mm along the length of the mounting arm.
[0026] The specific settings and functions of its adjustment device 6 and auxiliary components 7 will be described in detail below.
[0027] In this embodiment: the adjusting device 6 is installed on the surface of the second mounting arm 4. The adjusting device 6 includes a threaded rod 61 and a limiting block 62. The threaded rod 61 has an M20×3mm trapezoidal thread and a length of 300mm. The threaded rod 61 is fixedly connected to the side of the first mounting arm 3. The second mounting arm 4 has a through hole for the threaded rod 61 to pass through. The threaded rod 61 is clearance-fitted with the through hole. The limiting block 62 is fixedly connected to the end of the threaded rod 61 away from the first mounting arm 3. A gear 63 with 20 teeth and made of 45# steel is threaded onto the surface of the threaded rod 61. The gear 63 has a rotating tube 65 fixedly connected to its surface. The rotating tube 65 has anti-slip textures on its surface for easy manual rotation. It is 100mm long. A mounting bracket 64 is sleeved at the connection between the rotating tube 65 and the gear 63. The mounting bracket 64 is fixedly connected to the surface of the second mounting arm 4. A connecting block 66 is fixedly connected to the surface of the second mounting arm 4. A locking block 67 is slidably connected inside the connecting block 66. The locking block 67 is engaged with the surface of the gear 63. A sliding rod 68 is fixedly connected to the end of the locking block 67 away from the gear 63. A protrusion 69 is fixedly connected to the surface of the connecting block 66.
[0028] Specifically, the slide rod 68 is slidably connected inside the protrusion 69, and the end of the slide rod 68 away from the locking block 67 is fixedly connected to the blocking block 610.
[0029] In this embodiment: by setting the blocking block 610, the slide rod 68 can be limited, which reduces the possibility that the slide rod 68 may easily detach from the inside of the protrusion 69 during use, making it difficult for the slide rod 68 to limit the first spring 611.
[0030] Specifically, a first spring 611 is sleeved and connected to the surface of the slide rod 68. The first spring 611 is a cylindrical helical spring with a wire diameter of 2mm, a free length of 30mm, and a stiffness of 5N / mm.
[0031] Specifically, one end of the first spring 611 is fixedly connected to the surface of the protrusion 69, and the other end of the first spring 611 away from the protrusion 69 is fixedly connected to the surface of the locking block 67. The first spring 611 is provided to facilitate the application of a reset spring force to the locking block 67.
[0032] Specifically, the thread transmission ratio between gear 63 and threaded rod 61 is 1:5, and the distance between the mounting arms can be adjusted by 10mm with one revolution of rotating tube 65.
[0033] In this embodiment: an auxiliary component 7 is fixedly provided on the side of the second mounting arm 4. The auxiliary component 7 includes a groove 71 and a guide rod 72. The groove 71 is opened on the side of the first mounting arm 3. The guide rod 72 is fixedly connected to the side of the second mounting arm 4 near the first mounting arm 3. The guide rod 72 is slidably connected inside the groove 71.
[0034] In this embodiment, by setting the guide rod 72, the second mounting arm 4 can be limited, reducing the difficulty of the second mounting arm 4 moving smoothly when the equipment is in use.
[0035] Specifically, a guide block 73 is fixedly connected to the end of the guide rod 72 away from the second mounting arm 4. The guide block 73 is slidably connected inside the groove 71, and the fit clearance between the guide block 73 and the groove 71 is 0.1-0.3mm.
[0036] Working principle: When the equipment is in use, wooden boards 2 carrying steel plates 1 are enclosed to form a column casting space. The first mounting arm 3 and the second mounting arm 4 are then fitted onto the outer surface of the wooden boards 2 and securely connected by bolts 5. Cement is poured into the middle of the steel plates 1. Before the first mounting arms 3 and 4 are fitted onto the surface of the wooden boards 2, the spacing between them needs to be adjusted. Before adjustment, the push block 67 drives the slide rod 68 to move inside the protrusion 69 and connecting block 66. When the slide rod 68 and the push block 67 move together, they compress the first spring 611, generating elastic force. Then, the push block 67 disengages from the surface of the gear 63, and the rotating tube 65 drives the gear 63 to rotate inside the mounting frame 64. Because the gear 63 is threadedly connected to the threaded rod 61, and the threaded rod 61 is fixed... On the side of the first mounting arm 3, when the gear 63 rotates, it pushes or pulls the threaded rod 61, causing the first mounting arm 3 and the second mounting arm 4 to move relative to each other, thereby adjusting the encirclement size of the template. By setting the adjustment device 6, the first mounting arm 3 and the second mounting arm 4 can be effectively adjusted, which can adjust the distance between the first mounting arm 3 and the second mounting arm 4. This reduces the difficulty in adapting to different sizes of wooden boards 2 when using existing equipment, which is generally fixedly connected. This makes it difficult for the equipment to quickly and stably install wooden boards 2 of different sizes. Compared with the traditional fixed-spacing mounting arms, this invention can adapt to wooden boards with a width of 200-500mm, with an adjustment accuracy of ±1mm and an adjustment efficiency improvement of 60%. It realizes precise adjustment of the distance between the first mounting arm 3 and the second mounting arm 4, improving the adaptability of the equipment.
[0037] When the first mounting arm 3 and the second mounting arm 4 move relative to each other, the guide rod 72 moves synchronously with the second mounting arm 4 within the groove 71 of the first mounting arm 3. The movement of the guide rod 72 drives the guide block 73 to move within the groove 71. By setting the auxiliary component 7, the first mounting arm 3 and the second mounting arm 4 are effectively and smoothly moved, playing a stabilizing role during the adjustment of the first mounting arm 3 and the second mounting arm 4. This reduces the possibility of rotation during the movement and adjustment of the existing equipment, which makes it difficult to move and adjust the first mounting arm 3 and the second mounting arm 4 smoothly. This auxiliary component 7 ensures that the verticality deviation of the mounting arm during movement is ≤0.5mm / m, significantly reducing the risk of template deformation. The cooperation between the guide rod 72 and the guide block 73 ensures the smoothness of the mounting arm movement and improves the stability of the equipment.
[0038] The above description discloses only one or more preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of the present invention are still within the scope of the present invention.
