Light preset assembly type space net rack ribbed floor formwork and construction process

Abstract

The invention discloses a light preset assembly type space net rack ribbed floor formwork and a construction process. The light preset assembly type space net rack ribbed floor formwork comprises a plurality of metal keels arranged in parallel at intervals and a plurality of formworks with the two sides erected on every two adjacent metal keels; the formworks in the same column between every two adjacent metal keels are arranged one by one in a gapless mode; all the formworks and the metal keels define crisscross ribbed beam grooves; truss units perpendicular to the metal keels are arranged in the ribbed beam grooves in the same row; lower longitudinal ribs and upper longitudinal ribs parallel to the metal keels are arranged in the ribbed beam grooves in the same column; truss connecting pieces are locked on the metal keels; and the truss units, the lower longitudinal ribs and the upper longitudinal ribs integrally form a steel bar net rack and are detachably locked on the metal keels through the truss connecting pieces. According to the light preset assembly type space net rack ribbed floor formwork and the construction process, the investment of a large number of square timbers and formwork materials is greatly reduced, splicing is easy, assembling is rapid, the labor amount is small, the comprehensive manufacturing cost of an assembly type floor is reduced, the construction efficiency is improved, and the light preset assembly type space net rack ribbed floor formwork and the construction process conform to green and energy-saving buildings.

Description

【Technical field】 [0001] The invention belongs to the field of floor formwork support technology, and in particular relates to a light-duty pre-assembled space grid dense-rib floor formwork and a construction process. 【Background technique】 [0002] The existing ribbed slabs, hollow slabs, and cast-in-place beam-slab slabs on the market are all built on the support frame, and the main keel is set up, and then the required square wood sub-keel is set up on the main keel according to the space size of the floor slab, and the formwork is laid on the On the square wood, then manually place the axis and rib beam dimension lines on the formwork, and then place the filling box or disposable formwork on the formwork according to the construction drawing. The biggest disadvantage is that the filling box or disposable formwork is permanently embedded , can not be reused, which increases the corresponding cost, or the reusable formwork must be erected according to the traditional squar...

[0002] The existing ribbed slabs, hollow-core slabs, and cast-in-place beam-slab slabs on the market are all built on the support frame, and the main keel is set up, and then the required square wood sub-keel is set up on the main keel according to the space size of the floor slab, and the formwork is laid on the On the square wood, then manually place the axis and rib beam dimension lines on the formwork, and then place the filling box or disposable formwork on the formwork according to the construction drawing. The biggest disadvantage is that the filling box or disposable formwork is permanently embedded , cannot be reused, which increases the corresponding cost, or the reusable formwork must be erected according to the traditional square wood and formwork, and then the on-site high-altitude
