Description

Technical Field

[0001] This utility model belongs to the field of building formwork, and specifically relates to an aluminum formwork for construction. Background Technology

[0002] With the booming development of the construction industry, the requirements for formwork in construction are becoming increasingly stringent. It must not only have good construction performance, but also meet the needs of diverse building structures.

[0003] Currently, aluminum formwork, as a commonly used formwork material in modern construction, has advantages such as high strength, light weight, and reusability, and has improved the efficiency and quality of construction to a certain extent. However, existing aluminum formwork still has certain shortcomings in actual construction. Specifically, the floor heights of buildings often vary, but conventional aluminum formwork usually has a fixed height. Different specifications of aluminum alloy formwork are required for pouring concrete at different heights, which severely limits the applicability and practicality of aluminum alloy formwork structures.

[0004] Therefore, some existing aluminum alloy formwork for construction has begun to adopt height-adjustable structures. For example, Chinese patent CN222541986U discloses a novel adjustable aluminum alloy formwork structure. This structure has a second formwork body movably connected inside the first formwork body via a height adjustment mechanism. The height of the second formwork body can be adjusted through this mechanism, thereby adjusting the enclosure area and greatly facilitating construction, effectively improving construction efficiency and building quality. However, because the second formwork body in this aluminum alloy formwork structure is slidably installed inside the first formwork body, when the second formwork body rises, there will be a certain distance between its surface and the surface of the first formwork body. This can easily lead to unevenness in the formed wall surface and increase the workload of subsequent wall grinding. Utility Model Content

[0005] The purpose of this utility model is to address the problem that existing aluminum alloy formwork structures for construction cannot simultaneously achieve both flatness and adjustability during use. This invention proposes and designs an aluminum formwork for construction that allows for flexible adjustment of its enclosure height while ensuring the flatness of the poured concrete.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: an aluminum formwork for construction, comprising a fixed frame, a second template horizontally slidably mounted on the front side of the fixed frame, second slides provided at both ends of the rear side of the second template, a first vertical slide groove provided on the side of the second slide, both ends of the first vertical slide groove being connected to an inclined slide groove to the rear, the rear end of the inclined slide groove being inclined away from the first vertical slide groove; the rear end of the lower inclined slide groove being connected upward to the second vertical slide groove, and the rear end of the upper inclined slide groove being connected downward to the third vertical slide groove; two first templates are vertically slidably mounted on the front side of the fixed frame, the two first templates being symmetrically arranged on both sides of the second template; a first slide is provided at both ends of the rear side of the two first templates, the first slide being provided with a sliding engagement part, the sliding engagement part being rotatably mounted with a roller, the roller being able to slide within the first vertical slide groove, the inclined slide groove, the second vertical slide groove, and the third vertical slide groove. At this point, the present invention can control the second template to rise or fall during the vertical sliding of the two first templates by cooperating with the rollers and each sliding groove. That is, when the two first templates are in a close-fitting state, the second template is located behind the two first templates; when the two first templates are in a separated state, it is close to the two first templates respectively, thereby achieving the purpose of flexibly adjusting the height of the entire aluminum template structure enclosure, while ensuring that it has a high degree of flatness.

[0007] Furthermore, vertical guide rails are provided on both the left and right sides of the fixed frame, and vertical sliders are provided on the side of the first carriage. The vertical sliders are vertically slidably connected to the corresponding vertical guide rails. Thus, through the precise sliding connection between the vertical guide rails on both sides and the vertical sliders, stable and reliable vertical guiding support is provided for the sliding of the first template, ensuring its motion accuracy and stability in the vertical direction.

[0008] Furthermore, horizontal guide rails are provided on both the left and right sides of the fixed frame, and horizontal sliders are provided on both the left and right ends of the rear side of the second template. The horizontal sliders are horizontally slidably connected to the corresponding horizontal guide rails, thereby providing stable and reliable horizontal guiding support for the sliding of the second template through the precise sliding connection between the horizontal guide rails on both sides and the horizontal sliders, ensuring its motion accuracy and stability in the horizontal direction.

[0009] Furthermore, the horizontal distance between the first vertical slide and the second vertical slide, and the horizontal distance between the first vertical slide and the third vertical slide, are both greater than or equal to the thickness of the second template; the distance between the front side of the first template and the end of the roller closest to the first template is equal to the distance between the front side of the second template and the vertical center line of the second vertical slide, so as to ensure that the second template can be smoothly hidden behind the first template and can be aligned with the first template.

[0010] Furthermore, the highest point of the roller located on the lower first template is lower than the upper end face of the first template, and the lowest point of the roller located on the upper first template is higher than the lower end face of the corresponding first template; or the highest point of the roller located on the lower first template is at the same height as the upper end face of the corresponding first template, and the lowest point of the roller located on the upper first template is at the same height as the lower end face of the corresponding first template, so as to ensure that the upper and lower sets of rollers can slide smoothly in the first vertical groove without interference.

[0011] Furthermore, when the highest point of the roller on the lower first template is lower than the upper surface of the first template, and the lowest point of the roller on the upper first template is higher than the lower surface of the corresponding first template, the height of the first vertical groove is greater than that of the second template; when the highest point of the roller on the lower first template is at the same height as the upper surface of the corresponding first template, and the lowest point of the roller on the upper first template is at the same height as the lower surface of the corresponding first template, the length of the first vertical groove is equal to the height of the second template, so as to ensure that the second template can move smoothly from the rear of the two first templates to a position flush with the two first templates.

[0012] Furthermore, the second vertical slide groove is connected to the third vertical slide groove to ensure that both ends of the second template can fit into the corresponding first template.

[0013] Furthermore, a diagonal brace mounting plate is provided on the rear side of the fixed frame, and this diagonal brace mounting plate can be used as the mounting point for the diagonal brace.

[0014] As can be seen from the above technical solutions, this utility model has the following advantages: This utility model can control the second template to be located behind the two first templates when the two first templates are in a close-fitting state, and to be in close-fitting state with the two first templates respectively when the two first templates are in a separated state, thereby achieving the purpose of flexibly adjusting the height of the entire aluminum formwork structure; at the same time, based on the special matching groove structure in this utility model, it can have a high enclosure height and a high flatness in the entire aluminum formwork structure, thereby ensuring the quality of the poured concrete wall and reducing the amount of work for workers to grind the wall later.

[0019] like Figures 1 to 4 As shown, this utility model provides an aluminum formwork for construction, which includes a fixed frame 1. A diagonal brace mounting plate 2 is provided on the rear side of the fixed frame 1, and the diagonal brace mounting plate 2 can be used as the installation part of the diagonal brace to install the diagonal brace used to support the aluminum formwork for construction.

[0020] A second template 6 is horizontally slidably installed at the middle of the front side of the fixed frame 1. Specifically, as shown... Figure 1 , Figure 4 As shown, the present invention provides horizontal guide rails 3 on the inner sides of both the left and right sides of the fixed frame 1, and horizontal sliders 15 are provided at both ends of the rear side of the second template 6. The horizontal sliders 15 are horizontally slidably connected to the corresponding horizontal guide rails 3. Thus, the second template 6 is horizontally slidably installed at the middle position of the fixed frame 1 through the precise sliding connection between the horizontal guide rails 3 and the horizontal sliders 15. Moreover, as a preferred embodiment, the present invention can also provide horizontal stops at both ends of the horizontal guide rails 3 to prevent the second template 6 from falling off the fixed frame 1.

[0021] Two first templates 4 are vertically slidably installed on the front side of the fixed frame 1, and the two first templates 4 are symmetrically arranged on the upper and lower sides of the second template 6. Specifically, as shown... Figure 1 , Figure 3 As shown, the present invention provides vertical guide rails 8 on both the left and right sides of the fixed frame 1, and provides first slides 5 at both the left and right ends of the rear side of the two first templates 4; a vertical slider 9 is provided on the inner side of the first slide 5, and the vertical slider 9 is vertically slidably connected to the vertical guide rail 8 on the corresponding side, so that the first template 4 is vertically slidably installed on the fixed frame 1 through the precise sliding connection between the vertical guide rails 8 on both sides and the vertical slider 9.

[0022] Meanwhile, this utility model also provides a sliding engagement part 10 at one end of the first slide 5 near the second template 6, and a roller 11 is rotatably installed at the front end of the sliding engagement part 10; a second slide 7 is provided at both the left and right ends of the rear side of the second template 6, and a first vertical slide groove 12 is provided on the side of the second slide 7. Both ends of the first vertical slide groove 12 are connected to inclined slide grooves 13 to the rear. The rear end of the inclined slide groove 13 is inclined away from the first vertical slide groove 12; and the rear end of the lower inclined slide groove 13 is connected to the second vertical slide groove 16 to the upper inclined slide groove 13 to the lower vertical slide groove 14. The roller 11 can slide within the first vertical slide groove 12, the inclined slide groove 13, the second vertical slide groove 16, and the third vertical slide groove 14.

[0023] Furthermore, to ensure that the second template 6 can be smoothly concealed behind the first template 4 and aligned with it, the horizontal distance between the first vertical groove 12 and the second vertical groove 16, and the horizontal distance between the first vertical groove 12 and the third vertical groove 14, are both greater than or equal to the thickness of the second template 6. The distance between the front side of the first template 4 and the end of the roller 11 closest to the first template 4 is equal to the distance between the front side of the second template 6 and the vertical center line of the second vertical groove 16. The highest point of the roller 11 on the lower first template 4 is lower than the upper end surface of the first template 4, and the lowest point of the roller 11 on the upper first template 4 is higher than the lower end surface of the corresponding first template 4; or the highest point of the roller 11 on the lower first template 4 is at the same height as the upper end surface of the corresponding first template 4, and the lowest point of the roller 11 on the upper first template 4 is at the same height as the lower end surface of the corresponding first template 4. Furthermore, when the highest point of the roller 11 on the lower first template 4 is lower than the upper end face of the first template 4, and the lowest point of the roller 11 on the upper first template 4 is higher than the lower end face of the corresponding first template 4, the height of the first vertical groove 12 is greater than the height of the second template 6; when the highest point of the roller 11 on the lower first template 4 is at the same height as the upper end face of the corresponding first template 4, and the lowest point of the roller 11 on the upper first template 4 is at the same height as the lower end face of the corresponding first template 4, the length of the first vertical groove 12 is equal to the height of the second template 6.

[0024] When the rollers 11 installed on the first templates 4 on both sides are located in the middle of the first vertical slide groove 12, the two first templates 4 will be in a close fit, and the second template 6 will be hidden behind the first templates 4. When the first templates 4 on both sides move vertically away from each other, the rollers 11 installed on the first templates 4 on both sides move vertically with the two first templates 4. When they move to the connection between the first vertical slide groove 12 and the two inclined slide grooves 13, the upper end face of the lower first template 4 will be flush with or lower than the lower end face of the second template 6, and the lower end face of the upper first template 4 will be flush with or higher than the upper end face of the second template 6. Subsequently, when the first rollers 11 installed on the first templates 4 on both sides move vertically away from each other, the rollers 11 installed on the first templates 4 on both sides move vertically. As the templates 4 continue to move away from each other, the rollers 11 slide within their respective inclined grooves 13, pushing the second slide 7 forward until the rollers 11 mounted on the first templates 4 on both sides move to the connection points of the inclined groove 13 and the second vertical groove 16, and the inclined groove 13 and the third vertical groove 14, respectively. At this point, the front side of the second template 6 is aligned with the front side of the first template 4. Then, as the first templates 4 on both sides move vertically towards each other, the rollers 11 mounted on the first templates 4 on both sides move vertically along their respective second vertical grooves 16 and third vertical grooves 14, until the lower end of the second template 6 is in contact with the upper end of the lower first template 4, and the upper end of the second template 6 is in contact with the lower end of the upper first template 4. Moreover, preferably, the second vertical groove 16 and the third vertical groove 14 can be directly connected to ensure that both ends of the second template 6 can be in contact with the corresponding first template 4.
