Assembly type aluminum alloy form arranged at post-cast strip and construction joint positions

Abstract

The invention relates to an assembly type aluminum alloy form arranged at post-cast strip and construction joint positions. The form comprises a surface rib form body, a web form body and a bottom ribform body which are all made of aluminum alloy materials, a plurality of lower U-shaped grooves with upward openings and allowing bottom ribs to penetrate are formed in the upper end of the bottom rib form body at intervals, the web form body is installed at the upper end of the bottom rib form body, a plurality of upper U-shaped grooves with downward openings and allowing surface ribs to penetrate are formed in the lower end of the surface rib form body at intervals, and the surface rib form body is installed at the upper end of the web form body. The aluminum alloy form has the advantages that 1, a material is recycled, the cost is saved, and the material-saving requirement is met; 2, manufacturing is conducted according to the steel bar spacing, the structural slab and the protective layer thickness, it is ensured that after pouring is completed, the steel bar spacing standard and the protective layer thickness of the post-cast strip and the construction joint meet the design requirement, and the structural durability is ensured; and 3, all components of the form are tightly spliced, so that concrete leakage is avoided as much as possible, and the forming quality is ensured.

Description

technical field [0001] The invention relates to a post-cast belt and construction joint position assembled aluminum alloy formwork, which belongs to the manufacturing method and construction method of the post-cast belt and construction joint formwork in the field of construction engineering, and is suitable for concrete structural slabs adopting external waterproofing. Background technique [0002] In the field of construction engineering, most concrete structural slabs are designed with post-casting belts, and the area of ​​concrete structural slabs is too large to be poured at one time. At the joint position, formwork is required to separate the concrete. [0003] At present, the post-casting belts and construction joint position templates of most projects use quick-easy closing nets. The advantages of quick-easy closing nets are: 1) light weight, convenient transportation and installation; Due to the porosity of the net and the dense special mesh, the steel bars below 1...

Problems solved by technology

[0004] The disadvantages are: 1) Quick-Easy Closing Mesh is used as the template for the post-casting belt and construction joints. The Quick-Easy Closing Mesh is a flexible material and is easy to deform. After the pouring is completed, the post-casting belt is uneven, the appearance is poor, and the steel bars are seriously misaligned , the spacing between steel bars and the thickness of the protective layer cannot be guaranteed. Insufficient thickness of the protective layer will easily lead to excessive corrosion of the steel bars, and at the same time reduce the mechanical performance of the structural plate and reduce the durability of the structure; use, does not meet the material saving requirements, and is not conducive to cost saving; 3) the surface of the quick-easy closing net material is covered with mesh holes, which is prone to concrete grout leakage, which is not conducive to structural quality assurance
