Problems solved by technology

[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 composite 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 value

Embodiment 1

[0056] Embodiment 1: as attached figure 1 As shown, a cylinder is in the shape of a rectangular cylindrical enclosure, connected up and down, with a length and width of 1000 mm and a height of 250 mm. It is hot-pressed and formed by recycled waste plastic thin wall material, and it is mass-produced in a factory, with a wall thickness of 3 mm.

[0057] There is a 9cm wide inner extension plate 3 at the upper end of the plastic cylinder, and a 9cm wide outer extension plate 4 at the lower end of the cylinder. The four corners of the outer extension plate 4 are missing corners 5. There are connecting holes 7 with a diameter of 3 cm on the connecting plates at 5 places for the temporary connection of the construction site and the floor support 6 of the construction.

Embodiment 2

[0058] Example 2: as figure 1 As shown, a cylinder is in the shape of a rectangular cylindrical enclosure, connected up and down, and has a height of 250 mm. Aluminum alloy thin wall material is used for hot pressing and mass production in factory, with a wall thickness of 5mm. The cylinder body is composed of angle mold 13 and adjustment mold 14. The length and width of angle mold 13 are both 50cm. The width of adjustment mold 14 is divided into two specifications: 20cm and 30cm. Adjusting mold+angle mold, angle mold+adjusting mold+adjusting mold+angle mold, two directions adopt one of the above three combinations.

[0059] There is a 9cm wide inner extension plate 3 at the upper end of the aluminum alloy cylinder, and a 9cm wide outer extension plate 4 at the lower end of the cylinder. The four corners of the outer extension plate 4 are missing corners 5. There is a connecting hole 7 with a diameter of 3 cm on the connecting plate at the corner 5 for the temporary connecti...

Embodiment 3

[0060] Example 3: as image 3 As shown, a box body is shaped as a rectangular cavity, one side is open and the other end is closed, the length and width are 1000 mm, and the height is 250 mm. It is hot-pressed and formed by recycled waste plastic thin wall material, and it is mass-produced in a factory, with a wall thickness of 3 mm.

[0061] The open end of the plastic box body has a 9cm wide overhanging plate 4, the four corners of the overhanging plate 4 are missing corners 5, and the end of the overhanging plate 4 is a 9cm high connecting plate, and the connecting plate at the 5 missing corners has a connecting plate with a diameter of 3cm. The hole 7 is used for the temporary connection between the construction site and the floor support 6 under construction.

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.
