Problems solved by technology

However, the magnesium chloride used in method 1, because it contains chloride ions, has a thinning effect on concrete and a corrosion effect on steel bars. Method 2 has a slow production speed and is easy to separate the foam material from the plastic glue.
It can be seen that the method in the prior art basically needs manual production, the manufacturing speed is slow, the production cost is high, and it is not suitable for the production demand of the market

Embodiment 1

[0027] A method for manufacturing a lightweight filled mandrel provided in this embodiment comprises the following steps:

[0028] (101) The foam material is used as a core mold, and the surface of the core mold is covered with fiber mesh cloth.

[0029] The so-called foam materials include soft foam materials and structural foam materials, among which light foam materials are preferred, and polyphenylene is more preferred.

[0030] The so-called fiber mesh cloth has good alkali resistance, flexibility, and transverse and longitudinal tensile strength, and can be glass fiber mesh cloth or wall mesh cloth.

[0031] The surface is covered with fiber mesh cloth, and the fiber mesh cloth can completely surround the mandrel.

[0032] (102) Spray mortar on at least one side of the mandrel, and solidify it into shape.

[0033] Spraying mortar to the mandrel covered by the fiber mesh cloth can be sprayed on one side of the mandrel, or can be sprayed on multiple faces of the mandrel,...

Embodiment 2

[0041] (201) Select polyphenylene as the core mold, and cover the surface of the core mold with fiber mesh cloth.

[0042] So-called fiber scrims can cover multiple layers.

[0043] (202) Spray mortar on at least one side of the mandrel, and solidify and form it.

[0044] The spray mortar can be sprayed by mechanical spraying method.

[0045] Wherein, the sprayed mortar can be cement mortar and / or anti-crack mortar; the mortar can be powder mortar or fluid mortar.

[0046] The so-called mortar can also be formed by mixing the following components: 40-55% by weight of Portland cement, 2-6% by weight of adhesive, 33-40% by weight of aggregate, 5-12% by weight Heavy calcium in parts by weight, wood fiber and short glass fiber mixture in 0.5-1.5 percent by weight, plasticizer in 0.3-1.5 percent by weight.

[0047] Among them, the adhesive, aggregate, heavy calcium, wood fiber and short glass fiber mixture, and plasticizer can be dispersed and stirred to obtain a mixture; Portla...

Embodiment 3

[0053] Describe in detail through accompanying drawing and embodiment below, please refer to figure 1 , figure 1 It is a structural schematic diagram of a lightweight filled mandrel structure of the present invention.

[0054] A lightweight filled mandrel structure in this embodiment includes a foam material layer 301, at least one layer of grid cloth 302, a mortar layer 303 and a wrapping film 304, a foam material layer 301, a grid cloth 302 and a wrapping film 304 Connected in sequence, the mortar layer 303 penetrates between the foam material layer 301 and the wrapping film 304 , and is fused with the grid cloth 302 .

[0055] The mortar layer 303 is used to strengthen and fix the foam material layer 301 , and the wrapping film 304 is used to tightly wrap the foam material layer 301 and the mortar layer 303 .

[0056] The so-called foaming material layer 301 can be polyphenylene layer, and this foaming material is preferably polyphenylene; The so-called grid cloth 302 pla...

Abstract

The invention discloses a manufacturing method of a light filled core mold. The method comprises covering fiber gridding cloth on the surface of a core mold made of foaming materials; spraying mortar on at least one surface of the core mold for solidification forming; packing the core mold with heat shrink film and performing heating until the heat shrink film tightly packs the core mold. According to the manufacturing method of the light filled core mold, the core mold can be provided with higher strength and higher stability, the manufacturing speed is high, the production cost is low and mass or bath production applicable to the market can be obtained. The invention also provides a light filled core mold structure.

Description

technical field [0001] The invention relates to industrial and civil buildings, in particular to a lightweight filled mandrel structure and a manufacturing method thereof. Background technique [0002] Architecture is the general term for buildings and structures. It is an artificial environment created by people using material and technological means, scientific laws, Feng Shui concepts and aesthetic principles to meet the needs of social life. [0003] With the diversification of society, brick wall buildings have gradually failed to meet the needs of people. More and more construction projects adopt the technology of cast-in-place concrete hollow floors, and the use of this technology requires the use of lightweight filling mandrels. [0004] In the prior art, there are two methods for producing the filling mandrel. One is to wrap the glass fiber mesh cloth on the foam material by hand, and then apply the slurry made of magnesium oxide and magnesium chloride. After curing...
