Problems solved by technology

[0004] Although the prefabricated granary has been developed to a practical stage through the efforts of designers, and it has obviously improved the performance of fire prevention, rodent prevention, moisture resistance and reduced production costs, but as far as its current situation is concerned, the granary board structure of ordinary cement mortar It can't fundamentally improve its shortcomings of poor thermal insulation, and can't achieve the excellent effect of sealing, moisture-proof and insect-proof, let alone beautiful appearance and cheap economic effect.

Embodiment Construction

[0012] specific implementation plan

[0013] In order to make the outer surface layer 1 have a more decorative effect, in addition to the cement mortar with the ratio of 525# quick-hard sulfoaluminum cement and medium sand, cement pigments can also be specially added to produce a more obvious decorative effect. The weight ratio of the added pigment to cement is 1:0.04-1:0.06. In order to further improve its appearance characteristics, an appropriate amount of concrete brightener can also be added to the proportion of the outer layer 1. When using white dye as decorative color, a small amount of white cement can be added to further improve its aesthetic feeling.

[0014] The raw materials for making the core layer 2 are 525# quick hard sulfoaluminum cement and lightweight filler. The lightweight filler can use saw foam, rice husk or straw fiber. Taking saw foam as an example, the weight ratio of the added lightweight filler to 525# rapid-hardening sulfur-al...

Abstract

A prefabricated heat-nisulating light-weight plate for assembled granary is composed of internal and external high-strength cement mortar layers made up of high-strength fast-hardening sulpho-aluminous cement, and core layer with through holes and made of concrete and light-weight filler. The glass fibre fabric and dual-layer reinforcing bar net are used for strengthening its structure. Its advantages are light weight, high strength, high resistance to mouse, insect and moisture, and good insulating effect.

Description

technical field [0001] The invention belongs to the design and processing technology of prefabricated components in the construction field, and is especially suitable for the construction of prefabricated granaries. Background technique [0002] In a country with a population of 1.3 billion, grain storage and adjustment are extremely important and complex technical issues. The huge amount of grain storage has forced the national grain department to use a large number of temporary and simple granaries, including extremely backward and obsolete bamboo and reed mats. The consumables are huge, but the storage quality is not high, the cold and heat insulation performance is extremely poor, mildew and insects are infested, and rat plagues are common, resulting in a huge waste of food. Although the country has invested huge sums of money year by year, the modernized permanent granary is still far from meeting the basic requirements of reserves. The improvement...
