Problems solved by technology

[0004] Among them, the raw materials of foam material mandrel filling body and plastic mandrel filling body rely on chemical reaction to complete the raw materials, the environmental pollution is serious, and there are flammable and fragile cover ends, floating and broken during concrete pouring, and the construction is difficult.
[0005] Concrete mandrel filling body and prefabricated gypsum mandrel filling body, these two filling bodies are heavy and are basically made by manual pouring. They need long-term curing and drying, and a lot of labor is wasted in the process of making and using, which is easy Broken and damaged, the production efficiency and use efficiency are relatively low
[0006] The mandrel filling body of the light steel box body, in order to reduce the cost and resist floating, the light steel box body filling body is welded and formed with mesh thin steel plates. During the concrete pouring process, a large part of the cement mortar flows into the filling body through the mesh. In the box, the structural performance of the concrete is reduced, and there are hidden dangers affecting the quality of the building

Embodiment 1

[0030] A hollow floor mandrel filling body is characterized in that it at least includes the following raw materials: stone powder materials, fiber materials, starch, mold release agent and water.

[0031] The parts by mass of each raw material are: 60-80 parts of stone powder materials, 10-30 parts of fiber materials, 8-12 parts of starch, 0.5-1.5 parts of release agent, and 25-45 parts of water.

[0032] Stone powder materials are one or more of talcum powder, gypsum powder, double fly powder, calcium powder, fly ash, water treatment lime mud or other powdery industrial waste residues.

[0033] The fiber material is one or a mixture of waste paper powder fiber, crop straw fiber and wood powder fiber.

[0034] The starch refers to potato plant starch with high cohesiveness.

[0035] The release agent refers to a powdery or granular industrial release agent with good thermal stability, such as stearic acid, zinc stearate, etc.

Embodiment 2

[0041] In this example, the middle value of the material ratio is taken: 70 parts of stone powder material, 20 parts of fiber material, 10 parts of starch, 1 part of release agent, and 35 parts of water. The hollow floor mandrel filling body made by this ratio See Table 1 for comparison with the existing foam material mandrel filling body, concrete foam mandrel filling body, prefabricated gypsum mandrel filling body, and light steel box mandrel filling body.

Abstract

The invention belongs to the building domain, and relates to a hollow floor mandrel filling body and a manufacturing method thereof. The hollow floor mandrel filling body is at least prepared from, by mas s, 60-80 parts of mountain flour type material, 10-30 parts of fiber material, 8-12 parts of starch, 0.5-1.5 parts of release agent, and 25-45 parts of water. The hollow floor mandrel filling body adopts the high-temperature foaming principle of starch, and the finished product is light in weight, low in cost, big in flexibility, and more environment-friendly; moreover, the filling body can be industrially produced on a large batch; the manufactured mandrel filling body has smooth outer wall and porous inner part; thus the material dosage is reduced, the product weight is lightened, the product performance cost is greatly improved; moreover, the product can be shaped by compression molding in one time or separately; the filling body is assembled and shaped on site in use.

Description

technical field [0001] The patent of the invention belongs to the field of construction, and relates to a hollow floor mandrel filling body and a manufacturing method thereof. Background technique [0002] The cast-in-place concrete hollow floor structure technology can effectively solve the technical difficulties of forming holes in the cast-in-place concrete hollow floor. The large-span beamless design is realized, the storey height is reduced, the headroom is improved, and the overall cost of the project is reduced. [0003] Traditional mandrel fillings are divided into five categories: foam mandrel fillings, plastic mandrel fillings, concrete mandrel fillings, prefabricated gypsum mandrel fillings, and light steel box mandrel fillings. [0004] Among them, the raw materials of foam material mandrel filling body and plastic mandrel filling body rely on chemical reaction to complete, the environment is seriously polluted, and there are flammable and fragile closures, floa...
