Prefabricated reinforced concrete board molding bed and construction method

Abstract

The invention relates to a prefabricated reinforced concrete board molding bed and a construction method which replace frequently-used brick molding beds. According to the board molding bed, a prefabricated reinforced concrete shuttering body is mounted on an in-pit foundation bed through a connecting piece and a fastening piece in an enclosing mode, the shuttering body is of a rectangular prefabricated reinforced concrete shuttering body structure, a horizontal arc-shaped boss used for increasing height is arranged on the upper surface of the shuttering body, a horizontal arc-shaped groove used for increasing height and matched with the horizontal arc-shaped boss is formed in the lower surface of the shuttering body, namely the upper surface and the lower surface of the shuttering body are of a concave-convex matching structure, and evenly distributed horizontal through holes used for containing reinforced concrete sleeves are formed in the lateral sides of the shuttering body. The molding bed made of boards is simple in structure, easy and fast to install, fast in progress and high in quality. Installation is achieved on site in a one-shot mode. The boards can be cut, bricklaying is omitted, labor is saved, cost is saved, and the construction period is shortened.

Description

technical field [0001] The invention relates to a prefabricated reinforced concrete slab formwork and a construction method, which is a brand-new concrete slab formwork and construction method that replaces the currently commonly used brick formwork and construction. Background technique [0002] At present, in the construction industry, during the construction of traditional building foundations, the side forms such as foundation beams, independent caps, and sumps are not easy to remove. Generally, the soil is excavated separately, and brick tire molds are often used, that is, masonry brick tire molds. As a formwork; brick tire formwork requires construction workers to build bricks in the foundation pit, so a large construction space is required, which requires a larger area to be excavated when excavating the foundation pit. After the brick tire formwork construction is completed, the brick A dog’s space is formed between the tire mold and the wall of the foundation pit, a...

[0002] At present, in the construction industry, during the construction of traditional building foundations, the side forms such as foundation beams, independent caps, and sumps are not easy to remove. Generally, the soil is excavated separately, and brick tire molds are often used, that is, masonry brick tire molds. As a formwork; the brick tire formwork requires construction workers to build bricks in the foundation pit, so a large construction space is required, which requires a larger area to be excavated when excavating the foundation pit. After the brick tire formwork construction is completed, the brick A dog’s space is formed between the tire mold and the wall of the foundation pit, and a large amount of soil needs to be backfilled, which wastes manpower and material resources, increases the construction process, and prolongs the construction time. More manpower is invested, the cost is higher, the environment is easily polluted, the construction speed is slow and it is not conducive to ensuring the construction period
