[0093] A method for preparing the above-mentioned prefabricated high-strength floor deck, characterized in that it includes the following steps:

[0094] 1) Add the upper layer material, the middle material layer material and the lower layer material respectively into the respective mixers in the order of liquid, powder, fiber and sawdust and stir for 5-10 minutes;

[0095] 2) Paving the upper layer material and the lower layer material on the two-layer formwork, and laying glass fiber mesh cloth on the upper layer material and the lower layer material respectively;

[0096] 3) Lay the middle material layer above the lower layer;

[0097] 4) Turn the upper layer mechanically over the middle material layer;

[0098] 5) Send it to a hot press for hot pressing, the temperature is 70-150°C, the hot pressing pressure is 8-30MPa, and the hot pressing time is 15-30min;

[0099] 6) After the pressure is relieved, the formwork is removed, and the board is placed in an environment wit...

Abstract

The invention discloses a prefabricated high-strength floor deck and a preparation method thereof. The floor deck comprises an upper surface layer, a middle material layer and a bottom surface layer, wherein the upper and bottom surface layers are both composed of MgO, magnesium sulfate, water, fine wood chip, and polypropylene fibre, and the middle material layer is composed of MgO, magnesium sulfate, water, fine wood chip, mixed wood chip, and extra thick wood chip. Compared with the prior art, the floor deck can realize industrialization of building the floor deck, and overcome the disadvantages of intensive labor force, need for various work types, long completion period, and heavy workload in a traditional floor deck installation process.

Description

technical field [0001] The invention belongs to the field of prefabricated slabs, in particular to a prefabricated high-strength floor bearing slab and a preparation method thereof. Background technique [0002] The floor slab is also called composite floor slab, steel slab, profiled steel plate, floor slab, composite floor slab, etc. [0003] The floor slabs in traditional concrete buildings generally adopt the construction method of cast-in-place slabs with full formwork. The board has good performance, low cost and wide application basis. With the continuous development of construction requirements and related technologies, especially the continuous emergence of fast-construction steel structures and the diversification of building shapes, and environmental protection issues are increasingly important, the construction method of cast-in-place slabs has exposed its inevitable problems. This construction method has long construction period, time-consuming, consumable mate...
