Novel method for quickly assembling low-cost energy-saving house with prefabricated pole, beam, plate

Abstract

A novel method for rapidly assembling a low-cost energy-saving house with precast columns, beams and slabs comprises the steps of preparing house columns, beam molds and built-in reinforcing steel bars or profiled steel bars, pouring concrete grout into the molds, high-speed rotating in a centrifuge, curing, and demolding to obtain precast reinforced concrete columns and beam components; and inserting the precast columns on a cup foundation element, passing the precast beams through the preformed pores on the precast column, lapping precast floor slabs on the precast beams, and embedding wall slabs inside the embedding grooves of the precast beams, so as to form the major structure of the rapidly assembled low-cost energy-saving house. The inventive method has the advantages of application to industrial production, no air holes in components, high density, high strength, long service life, standardized production, low production cost, low time and raw materials consumption, rapid house construction speed, and high quality; and is a novel energy-saving house construction method in the construction field.

Description

Technical field: [0001] The invention relates to a house building method, in particular to a new method for quickly assembling a low-cost energy-saving house by using prefabricated columns, beams and plates. Background technique: [0002] Existing building technologies are classified into block type, on-site reinforced concrete type, steel structure type, etc. according to the materials used, but all have their own shortcomings. For example, the largest proportion of block-type buildings has evolved from building houses with stones and soil in the early days to the widespread use of bricks or hollow blocks to build walls and buildings. Reinforced with reinforced concrete ring beams and structural columns to build multi-storey houses, the disadvantages are that the labor consumption is large, the total amount of building blocks is large, the transportation volume is large, the wall area is large, the living area is reduced, and the windows cannot Too large will result in a narrow ...

AI Technical Summary

Problems solved by technology

Using reinforced concrete ring beams and structural columns to reinforce and build multi-storey houses has the disadvantages of large labor consumption, a large amount of building blocks, a large amount of transportation, a large area of ​​the wall, and a reduction in the living area. Windows cannot If it is too large, it will result in a narrow depth and take up more house land, and also make the ratio of the surface area of ​​the outer wall to the effective living room area too large without heat preservation and consume more air-conditioning energy consumption

On-site pouring of reinforced concrete building formwork consumes a lot of labor and loading and unloading. The concrete poured on site under atmospheric pressure has many pores, is loose, and has limited bonding force with steel bars and low strength. Therefore, thick columns, fat beams and thick slabs have to be used, resulting in waste of raw materials. Large, long construction period, high cost

Due to the limited compressive strength of steel, there is no concrete to increase the compressive strength of the all-steel structure building, which greatly increases the consumption of steel and high cost, and has the disadvantages of not being fireproof or rustproof.
