Description

Technical Field

[0001] The present invention belongs to the technical field of ultra-low energy consumption, energy-saving and earthquake-resistant walls, and specifically relates to a passive ultra-low energy consumption, energy-saving and earthquake-resistant wall structure construction process. Background Art

[0002] In the traditional construction sector, residential energy consumption has long been a major issue plaguing the industry. With the intensification of the global energy crisis and rising environmental awareness, reducing building energy consumption and improving energy efficiency have become key development directions for the construction industry. However, existing ordinary residential buildings still have significant deficiencies in energy efficiency and structural safety. Traditional building envelopes suffer from poor thermal performance and the widespread presence of thermal bridges, leading to high energy consumption for heating in winter and cooling in summer. Furthermore, conventional brick-concrete or frame structures are prone to wall cracking and joint failure under strong earthquakes. In particular, weak areas such as door and window openings lack effective reinforcement measures, making them difficult to meet the seismic requirements of high-intensity earthquake zones. In the construction of cast-in-place concrete structures, large errors in rebar binding and discontinuous insulation layer splicing are common, leading to structural safety risks and compromising energy efficiency. Furthermore, the lack of standardized process guidance results in long construction periods and uncontrollable costs. Summary of the Invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, by adopting an integrated insulation board, heat conduction is greatly reduced, and the energy consumption of heating in winter and cooling in summer is reduced. Insulation boards are laid on the foundation cushion and the periphery of the raft to block the cold and hot bridge effect and improve the overall air tightness. At the same time, by continuously wrapping the insulation layer (walls, foundations, roofs), the ultra-low energy consumption standard of the building envelope structure is achieved.

[0020] 2. In the present invention, by setting a 20 cm thick wall configuration and double-layer bidirectional steel bars (with a gap of 20 cm) in the house, and adding two reinforcing bars at the door and window openings, the local shear resistance of the house is improved, and L-shaped / T-shaped seismic columns (C14-C20 steel bars), beams (4 C25 bottom bars), and raft slabs are arranged inside the house, so that the foundation forms a rigid whole, meets the 8-degree seismic fortification requirements, and improves the seismic resistance of the house. At the same time, the setting of 45 cm thick P6 impermeable concrete + hidden beams (5 steel bars) disperses the seismic force and prevents uneven settlement of the house.

[0021] 3. In the present invention, the simultaneous construction of cast-in-place concrete shear walls and insulation boards reduces the need for overlapping processes, shortens the construction period, and improves construction efficiency. At the same time, the use of standardized steel formwork ensures the flatness of the wall and avoids the occurrence of hollowing in the later plastering. BRIEF DESCRIPTION OF THE DRAWINGS
