Abstract

The invention provides a construction method of a prefabricated multi-ribbed cavity floor, and belongs to the technical field of prefabricated multi-ribbed plate construction. The construction method of the prefabricated multi-ribbed cavity floor comprises the steps of full-hall scaffold building, main keel laying, overall leveling and the like. The construction method comprises the steps that S1, full-hall scaffold building is conducted, specifically, when a full-hall scaffold is built, vertical rods on the upper layer and the lower layer are required to be aligned, the vertical rods are uniformly arranged from the two sides of a cast-in-place ribbed beam, the vertical rods are arranged at the intersection positions of floor elastic bidirectional lines, and scaffold boards are laid under the vertical rods; S2, main keels are laid, specifically, when the main keels are installed, the main keels are required to be arranged in order and not to be inclined, and the two vertical rods at the intersection positions must abut against the main keels; and S3, overall leveling is conducted, specifically, after the main keels are laid, overall leveling is conducted according to control lines, and full-hall scaffold formworks are hoisted on the main keels. The cavity formworks are supported by placing the modularized cavity formworks which are machined and formed in a factory-like mode, and accurate and rapid installation of an upper plate of the prefabricated multi-ribbed plate is achieved by installing limiting square pipes.

Description

Technical field

[0001] The present invention belongs to the prefabricated ribbed construction technology, in particular, to a prefabricated rib cavity floor construction method.Background technique

[0002] In order to improve labor productivity, reduce resource energy consumption, improve architectural quality and improve the quality of human residence, and the proportion of construction industries has increased year by year. The prefabricated macrostic cavity floor is a prefabricated component of the prefabricated cavity floor system, which solves the defects such as current-in-place concrete, and to generate shrinkage cracks, improve the changes and flexibility of building space. Sex.

[0003] However, in the existing construction method, more dependence on the template, wood, etc., usually, to the sporadic cutting of the template, wood, etc., and template The shackles are closed, strong, and the concrete slurry is oozed from the preform ribs when the pouring.Inventive content

Embodiment

[0039]Refer to the attachmentfigure 1 As shown, the present invention provides a technical solution: a prefabricated rib cavity floor construction method, including the following steps:

[0040]S1, full hall scaffolding: When a full view is 10, it is required to align the vertical rod 11 alignment, and the vertical rod 11 is arranged from the two sides of the current ribs 20, and set up in the intersection of the floor bomb bidder. The rod 11, the vertical rod 11 is placed on the foot plate 12.

[0041]Specifically, when the full hall scaffold 10 is built, the vertical rod 11 must not be placed directly on the floor; and the length of the footboard 12 should be greater than or equal to 300 mm to make the vertical rod 11 loaded a uniform distribution of the floor panel surface, transfer to the lower layer. On the floor.

[0042]S2, laying the main ribs: When the main ribs 30 are installed, the main ribs 30 are required to be neat, not skew, and the two vertical rods 11 and the main keel 30 mu...
