Cover die for construction of composite-section ribbed floor and construction method thereof

Abstract

The invention discloses a cover die for construction of a composite-section ribbed floor and a construction method thereof. The cover die comprises two cylinders or one cylinder and one box or two boxes, wherein each cylinder is of a cylindrical surrounding body structure of which the upper part and lower part are communicated; the cylinders comprise a cylinder I and / or a cylinder II; each box isof a cavity body structure of which one end is opened and the other end is sealed; the boxes comprise a box I and / or a box II; the cylinder I is sheathed above the exterior of the cylinder II, and / orthe box I is sheathed above the exterior of the cylinder II, and / or the box I is sheathed above the exterior of the box II; a lower flange die cavity of a cast-in-situ concrete rib is formed between the cylinder and / or the box; a web plate die cavity of a cast-in-situ concrete dense rib is formed between the adjacent cylinders and / or the boxes. One of the cover die is reserved in a reinforced concrete prefabricated rib cylinder or box, and the other one is a detachable and repeatedly used cylinder die, or is a prefabricated concrete cylinder reserved in the floor. The cover die is a construction die with the advantages that the production is simple; the construction is convenient; the construction period is short; the manufacturing cost is low; the good use effect is obtained.

Description

technical field

[0001] The invention relates to a concrete superimposed cross-section densely ribbed floor, in particular to a set of formwork for the construction of a superimposed cross-section densely ribbed floor and a construction method thereof, belonging to the technical field of building structures and construction. Background technique

[0002] The cast-in-place concrete ribbed floor is a floor structure with excellent performance and good economy. It is widely used in construction projects. However, because it adopts the all-cast-in-place construction technology, it not only has a long construction period, but also does not conform to the national development of assembly methods. Therefore, the development of a superimposed cross-section ribbed floor with simple construction, short construction period, low cost and high assembly rate can not only reflect the industrialization level of the country's development of prefabricated structures, but also have good economic...
