Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum formwork connection and reinforcement technology, specifically to an aluminum formwork connection and reinforcement structure for high-rise buildings with different floor heights. Background Technology
[0002] Aluminum formwork casting is a highly efficient and precise concrete structure forming technology in modern construction engineering. Its core lies in using a high-strength aluminum alloy formwork system to replace traditional wooden or steel formwork. This system is precisely assembled from standardized aluminum profile panels, supporting components, fasteners, and a matching early stripping system, offering significant advantages such as light weight, high strength, corrosion resistance, and high reusability (typically hundreds of times). Before construction, the aluminum formwork needs to be prefabricated and pre-assembled in a factory according to detailed design drawings to ensure accurate dimensions and tight joints, laying a solid foundation for subsequent high-quality concrete forming. During casting, the aluminum formwork, with its excellent rigidity and smooth surface, effectively resists the lateral pressure of the concrete, significantly reducing the risks of formwork bulging and grout leakage, thus accurately shaping the required component shape, geometric dimensions, and surface flatness. It is particularly suitable for highly standardized structural components such as shear walls, columns, beams, and floor slabs. After the concrete is poured into the formwork, it is thoroughly vibrated to ensure compaction, and its curing process is no different from traditional methods. The core value of the aluminum formwork system lies in its "early removal" characteristic: once the concrete reaches a certain early strength (usually 1-2 days), most of the formwork panels and horizontal supports can be safely and quickly removed while retaining vertical supports, enabling extremely early formwork turnover and significantly shortening the construction cycle. After simple cleaning and maintenance, the dismantled aluminum formwork can be quickly reused for the next floor or building, significantly improving construction efficiency and reducing material waste and labor costs. In summary, aluminum formwork casting technology, through its industrialized production, high-precision molding, rapid turnover, and environmentally friendly and energy-saving features, effectively improves the overall quality, construction speed, and economic benefits of building structures, and has become one of the important technical means to promote the development of industrialized construction.
[0003] Currently, many high-rise residential buildings, in response to policy requirements, as well as affordable housing and apartments, incorporate standard floors of varying heights within a single high-rise building to meet diverse needs. While using aluminum formwork and climbing scaffolding can save on construction costs for high-rise residential buildings, traditional aluminum formwork construction techniques can be quite difficult and have certain drawbacks when constructing aluminum formwork with varying floor heights.
[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0029] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0030] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides an aluminum formwork connection and reinforcement structure for high-rise buildings with different floor heights, comprising:
[0031] A standard aluminum mold 1 is vertically set on the surface to be poured. There are multiple pairs of standard aluminum molds 1, and each pair of standard aluminum molds 1 is provided with tie bolts 2 for positioning.
[0032] Diagonal brace 3 is disposed between the standard aluminum mold 1 and the surface to be poured, and the diagonal brace 3 is used to support and fix the standard aluminum mold 1.
[0033] Additional plate 4 is mounted on the upper surface of the standard aluminum mold 1. The additional plate 4 has a back rib 5 on its exterior and the tie bolt 2 is mounted on the back rib 5.
[0034] In this embodiment, the additional plates 4 are stacked, and at least one layer of additional plates 4 is provided. During concrete pouring and formwork erection, after the steel mesh is fixed and welded on the surface to be poured, a standard aluminum formwork 1 is vertically installed outside the steel mesh, and supported and fixed using tie bolts 2 and diagonal braces 3. Then, the number and quantity of additional plates 4 required are determined based on the amount by which the concrete pouring height exceeds the pouring height of the standard aluminum formwork 1. After confirming the number and quantity of additional plates 4, tie bolts 2 are used to connect and reinforce the additional plates 4, completing the formwork erection. Finally, concrete is poured into the formwork to complete the concrete pouring process.
[0035] For example, if the standard aluminum formwork 1 has a casting height of 3m and the single-layer additional plate 4 has a casting height of 0.3m, then when a building with a floor height of 3.3m needs to be cast, an additional plate 4 is installed on the top surface of the standard aluminum formwork 1. Similarly, when a building with a floor height of 3.6m needs to be cast, two additional plates 4 are installed on the top surface of the standard aluminum formwork 1.
[0036] Furthermore, the tie bolt 2 includes:
[0037] A connecting screw 6 is inserted through the object to be fixed.
[0038] Two fastening nuts 7 are provided, and the two fastening nuts 7 are threadedly installed on the connecting screw 6, and the fastening nuts 7 abut against the outer wall of the object to be fixed.
[0039] In this embodiment, after the standard aluminum mold 1 or the back rib 5 is fixedly installed, the connecting screw 6 is used to pass through the standard aluminum mold 1 or the back rib 5, and the fastening nut 7 is screwed into the connecting screw 6 from the outside of the standard aluminum mold 1 or the back rib 5. When the fastening nut 7 abuts against the outer side of the standard aluminum mold 1 or the back rib 5, the installation and fixing of the standard aluminum mold 1 or the additional plate 4 is completed.
[0040] Furthermore, the diagonal brace 3 includes:
[0041] The fixed base 8 is fixedly installed on the ground to be poured by bolts.
[0042] Connecting seat 9, which can be detachably installed on the object to be fixed, and two connecting seats 9 are provided, and the two connecting seats 9 are located at different heights.
[0043] A support adjustment rod 10 is rotatably mounted between the fixed base 8 and the connecting seat 9, and the support height of the support adjustment rod 10 is adjustable.
[0044] In this embodiment, the support adjustment rod 10 includes: an adjustment sleeve 11, the adjustment sleeve 11 having an adjustment thread inside; and two adjustment screws 12, which are respectively threaded onto both ends of the adjustment sleeve 11, with the outer ends of the adjustment screws 12 rotatably connected to the fixed base 8 and the connecting seat 9.
[0045] When installing the diagonal brace 3, firstly, the fixed base 8 and the connecting seat 9 are fixedly installed onto the surface to be poured using bolts. Then, one of the adjusting screws 12 is detachably and rotatably installed onto the fixed base 8 using a pin and a latch. Finally, the adjusting sleeve 11 is rotated to simultaneously close or separate the two adjusting screws 12, thereby reducing or increasing the support length of the diagonal brace 3. When the support length of the diagonal brace 3 matches the distance between the fixed base 8 and the connecting seat 9, the other adjusting screw 12 is detachably and rotatably installed onto the connecting seat 9 using a pin and a latch, completing the installation of the diagonal brace 3.
[0046] In one specific embodiment, two limiting nuts 13 are threaded onto the adjusting screw 12, and the two limiting nuts 13 respectively abut against both ends of the adjusting sleeve 11. After the support length of the diagonal brace 3 is adjusted, the two limiting nuts 13 are rotated to the position abutting against the adjusting sleeve 11. The limiting nuts 13 can restrict the two adjusting screws 12 from closing, thereby ensuring the stable support and positioning of the diagonal brace 3 for the standard aluminum mold 1 and the additional plate 4.
[0047] Compared with the prior art, the present invention has at least the following beneficial effects:
[0048] This utility model, based on a standard aluminum formwork, adds an additional plate and uses back ribs and tie bolts for fixation, enabling it to handle concrete pouring work of different floor heights without the need for customized aluminum formwork according to floor height, greatly reducing the cost of concrete pouring. It features a simple structure and convenient operation.
[0049] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
