Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building materials, in particular to a low-cost aluminum alloy template reinforced profile. Background Art
[0002] With the advancement of modern construction technology and aluminum processing technology, aluminum formwork has become the mainstream direction of application and development in today's construction industry. Building formwork made of aluminum alloy is the promotion of prefabricated concrete technology and the embodiment of the industrialization of construction technology.
[0003] It has been found in actual use that the existing aluminum alloy templates have the following deficiencies:
[0004] The existing aluminum alloy formwork is extruded by special equipment, and the deformation is large under stress. In order to improve the strength of the aluminum alloy formwork, it is necessary to weld reinforcing ribs on the surface of the aluminum alloy formwork, and due to the rigidity problem, a large number of transverse ribs need to be added for coordination. However, in the production process, welding technology needs to be used on a large scale. Since the transverse ribs span the aluminum formwork, the aluminum formwork after welding is prone to serious deformation due to excessive stress concentration, affecting the molding effect of concrete;
[0005] Moreover, in the actual use of the existing aluminum alloy templates, the templates of the aluminum alloy structure improve the structural strength by strengthening the structure and increasing the cross-section, but the stronger the structure, the greater the rigidity and the greater the stress effect. When the structure is bent, the greater the bending stress at the location of the weld, the greater its influence. The longitudinal and transverse welds on the structure generate tensile stress on a relatively large cross-section. Although the distribution range on the length of the component is not too large, it still has a great influence on the rigidity. The rigidity decreases significantly when loading, which will cause serious restrictions on the aluminum alloy structure and significantly increase the cost of the structure.
[0006] Therefore, the present application provides low-cost aluminum alloy formwork reinforcement profiles to meet the needs. Utility Model Content

DETAILED DESCRIPTION
[0027] like Figure 1 , Figure 2 and Figure 3A low-cost aluminum alloy formwork reinforced profile is shown, and an embodiment of the utility model provides: an aluminum alloy formwork 1, a reinforcing rib 2, a reinforcement strip 3 and a web 4. The aluminum alloy formwork 1 is composed of an aluminum profile base plate 101, a longitudinal side frame 102 and a transverse side frame 103. The longitudinal side frames 102 are vertically installed on the left and right sides of the aluminum profile base plate 101, and the transverse side frames 103 are transversely installed on the upper and lower ends of the aluminum profile base plate 101. The inner side of the aluminum alloy formwork 1 is installed with a reinforcing rib 2, the upper end of the reinforcing rib 2 is installed with a reinforcement strip 3, the lower end of the reinforcement strip 3 is provided with a slot 301, and the side of the reinforcement strip 3 is installed with a web 4.
[0028] In this embodiment, two groups of reinforcing ribs 2 are provided, and the two groups of reinforcing ribs 2 are integrally formed by the aluminum profile bottom plate 101 .
[0029] In this embodiment, the reinforcing rib 2 is in the shape of a rectangular strip. The reinforcing rib 2 extends vertically upward and is perpendicular to the aluminum profile base plate 101. The upper and lower ends of the reinforcing rib 2 are respectively welded and fixed to the lateral side frames 103 at the upper and lower ends of the aluminum profile base plate 101. The reinforcing rib 2 is welded and fixed to the lateral side frames 103, which can improve the stability of the reinforcing rib 2.
[0030] In this embodiment, the reinforcement strips 3 are in the shape of long strips. Two groups of reinforcement strips 3 are arranged, and the two groups of reinforcement strips 3 are transversely installed at the upper end of the reinforcing ribs 2. The reinforcement strips 3 can support the longitudinal side frames 102 and share the lateral pressure for the transverse side frames 103.
[0031] In this embodiment, the reinforcement strip 3 is clamped downwardly through the slot 301 at the outer end of the upper edge of the reinforcing rib 2. The reinforcement strip 3 and the reinforcing rib 2 are in a "well" shape as a whole. The reinforcement strip 3 is mounted on the reinforcing rib 2. The reinforcement strip 3 is clamped at the outer end of the upper edge of the reinforcing rib 2 through the slot 301 to form a support point. The reinforcement strip 3 is divided into three sections by two groups of reinforcing ribs 2, which can shorten the support arm, improve the supporting property of the reinforcement strip 3, reduce the risk of deformation of the reinforcement strip 3, increase the load-bearing force of the template, and enhance the template's ability to resist deformation.
[0032] In this embodiment, the longitudinal side frame 102 is in the shape of an "I", and the left and right ends of the reinforcement strip 3 are respectively welded to the lower corners of the longitudinal side frame 102. The left and right ends of the reinforcement strip 3 are against the lower corners of the "L" shape of the longitudinal side frame 102, which can ensure the welding area of the reinforcement strip 3.
[0033] In this embodiment, the web 4 is vertically installed in the middle of the reinforcement strip 3, and the web 4 and the reinforcement strip 3 are in the shape of an "I" as a whole, and there is a gap between the web 4 and the aluminum profile bottom plate 101. When the aluminum alloy template 1 is subjected to downward pressure perpendicular to the axis, the aluminum profile bottom plate 101 and the longitudinal side frame 102 are bent, and compression deformation occurs in the upper part of the aluminum alloy template 1, that is, compressive stress occurs. The closer to the upper edge of the lateral side frame 103, the more severe the compression. By designing the web 4 in the cross-section of the reinforcement strip 3, the web 4 farthest from the centroid is mainly used to resist the bending moment, because the farther the web 4 is, the greater the moment of inertia generated, and the web 4 is mainly used to resist the shear force, and the middle part of the aluminum alloy template 1 is neither stretched nor compressed, so there is no stress. Compared with the existing structure, it can make full use of the mechanical properties of the material, save a lot of aluminum, and save the production cost of the aluminum alloy template.
