Cordwood type mold for multi-ribbed structure and construction method of cordwood type mold

A construction method and building-block technology, applied in the direction of formwork/formwork/work frame, formwork treatment, building structure, etc., can solve the problem that the construction of the bottom flange of the dense rib cannot meet the requirements, the rib spacing cannot meet the optimal spacing, Due to the large amount of steel used at the bottom of the dense rib, the effect of being conducive to on-site handling and installation, minimizing the amount of concrete and rationalizing the structure of the dense rib

Problems solved by technology

[0002] The concrete ribbed slab structure constructed by using plastic formwork as the mold has a history of decades. The existing defects are: 1) Due to the limitation of the demoulding method, it cannot meet the requirements for the construction of the bottom flange of the densely ribbed, so that the densely ribbed The bottom has a large amount of steel due to the small cross-section of the compression area, and the thickened cross-section of the tension area due to the small width of the cross-section makes the consumption of concrete large; 2) Since the weight of the plastic formwork is limited by manual handling and installation, its is limited so that the rib spacing cannot meet the optimal spacing

Abstract

The invention discloses a cordwood type mold for a multi-ribbed structure and a construction method of the cordwood type mold and belongs to the technical field of construction materials. The cordwoodtype mold comprises a middle mold and wedge molds. The periphery of the middle mold is connected with the wedge molds. The four corners of the middle mold are all connected with corner molds and bothends of each corner mold are connected with the corresponding wedge molds. According to the cordwood type mold, construction mold requirements of the novel multi-ribbed plate structure with the design of a bottom flange, a sub-rib, a secondary rib and a web plate stiffening rib can be met. Compared with a traditional multi-ribbed plate structure for plastic mold shell construction, the novel multi-ribbed plate structure is less in concrete dosage, more reasonable in spacing of ribs and more economical in structure. Compared with a traditional plastic mold shell, the cordwood type mold is moreconvenient to produce, carry, install and dismount.

Description

technical field [0001] The invention relates to a concrete dense rib structure, in particular to a detachable and reusable building block mold for the construction of a concrete dense rib structure and a construction method thereof, belonging to the technical field of building materials. Background technique [0002] The concrete ribbed slab structure constructed by using plastic formwork as the mold has a history of decades, and the existing defects are: 1) Due to the limitation of the demoulding method, it cannot meet the requirements of the construction of the bottom flange of the densely ribbed, so that the densely ribbed The bottom has a large amount of steel due to the small section in the compression area, and the thickened section in the tension area has a large amount of concrete because the section width is too small to fit the steel bars; 2) Since the weight of the plastic formwork is limited by manual handling and installation, its is limited, so that the rib spa...
