A kind of magnesium oxysulfide reinforced truss plate

Abstract

The invention discloses a magnesium oxysulfate steel bar truss board and a manufacturing method thereof. The magnesium oxysulfate steel bar truss board comprises multiple rows of steel bar trusses and magnesium oxysulfate boards; the steel bar trusses are buried in the magnesium oxysulfate boards and arranged in parallel, and the magnesium oxysulfate boards are fixed by using own coagulability and the condensation of the steel bar trusses. The invention further discloses the manufacturing method of the magnesium oxysulfate steel bar truss board. The fixation is conducted by using the coagulability of the magnesium oxysulfate boards and the condensation of the steel bar trusses, and the fixity is good; the magnesium oxysulfate boards are not prone to being corroded, and parts, inserted into the magnesium oxysulfate boards, of the steel bar trusses are not prone to being corroded either; after concrete construction is conducted, the magnesium oxysulfate boards do not need to be removed from the steel bar trusses, the surfaces of the magnesium oxysulfate boards are smooth and flat, and due to the fact that magnesium oxysulfate is white, the operations of plastering and scraping can be eliminated.

Description

technical field [0001] The invention relates to a magnesium oxysulfide reinforced truss plate and a manufacturing method thereof. Background technique [0002] At present, the widely used reinforced truss floor deck is mainly composed of reinforced trusses and profiled thin steel plates, and the reinforced trusses and profiled thin steel plates are welded, wherein the profiled thin steel plates are used as templates. The profiled thin steel plate is easily corroded; the surface of the steel plate has uneven concave-convex lines, and the surface of the steel plate needs to be adjusted with plaster and putty. However, the surface of the steel plate is smooth, and it is difficult for plaster and putty to firmly bond and the surface of the steel plate is gray, and it needs to be scraped and whitened. Due to the above-mentioned defects of the steel plate, the profiled thin steel plate is generally removed from the steel truss after the concrete construction of the floor. Howeve...

Problems solved by technology

[0003] CN201510010654 discloses a steel truss gypsum board. The bottom of the steel truss support is inserted and fixed in the fiber gypsum board. Since the gypsum is neutral or slightly acidic in terms of acidity and alkalinity, it cannot form a passivation layer on the surface of the steel bar for protection, so its The section where the steel truss is inserted into the fiber plasterboard is susceptible to corrosion, reducing the safety of the structure

The volume expansion of the corroded steel bars will cause the fiber gypsum board to be swelled and cracked, which is not beautiful

In addition, as we all know, the strength of gypsum is generally low, and the water resistance is poor, and the interface between gypsum and cement-based concrete will form volume-expanding ettringite, causing the two to separate from each other, hollowing out, and the mechanical properties will decline

[0004] At the same time, most of the existing cast-in-place wall panels are molded and supported on site. After the construction is completed, the molds need to be removed and plastered. The operation is cumbersome and the work efficiency is low.
