Description

Technical Field

[0001] This utility model relates to the field of prefabricated wall technology, and in particular to a new type of prefabricated wall for building engineering. Background Technology

[0002] With the rapid pace of urbanization and the increasing density of urban populations, high-rise buildings are springing up like mushrooms after rain, becoming a key means to solve the shortage of living and office space. Traditional masonry walls, due to their large self-weight, significantly increase the vertical load of buildings and impose stringent requirements on the foundation bearing capacity. This not only raises the cost of foundation construction but also restricts the expansion of building height to a certain extent. For example, the common 240 mm thick clay brick masonry exterior wall can reduce the weight by 30% for the same volume, which meets the demand for lightweight structure in high-rise buildings and facilitates the design of more flexible and efficient building structure systems.

[0003] Currently, precast wall connections on the market primarily rely on cement mortar grouting. Traditional precast concrete walls are mostly made of ordinary silicate cement and sand, which, while possessing a certain strength, suffer from significant issues such as heavy weight and poor toughness. During natural disasters like earthquakes, they are prone to cracking and damage, seriously endangering the overall safety of the building. Furthermore, their thermal insulation largely depends on external insulation boards or internal rock wool filling, a complex process where the insulation layer is prone to detachment and moisture-induced failure at the joints. Over long-term use, energy consumption is difficult to control effectively. Additionally, cement mortar is significantly affected by environmental humidity and temperature. In humid and rainy weather, the hardening process is slowed, resulting in slower strength growth and extended construction periods. In low-temperature environments, it is prone to freezing and expansion, damaging the internal structure and drastically reducing connection strength. Moreover, manual grouting makes it difficult to ensure density and uniformity, easily creating pores and voids that pose risks of rainwater leakage and air infiltration, compromising the wall's waterproofing, insulation, and overall stability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a new type of precast wall for building engineering, which aims to improve the problem that cement mortar is significantly affected by environmental humidity and temperature in the existing technology, and the setting and hardening process is delayed in humid and rainy weather.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel precast wall for building construction, comprising a support frame one and a support frame two.

A threaded sleeve is threadedly connected to the top of the threaded shaft 1. An mounting plate is fixedly connected to the bottom of the fixing plate 2.

[0008] As a further description of the above technical solution:

[0009] A protective pad is fixedly connected to the outer side of the outer wall of the fixing plate, and expansion screws are fixedly connected to the four corners of the top surface of the mounting plate.

[0010] As a further description of the above technical solution:

[0011] An adjustment plate is fixedly connected to the rear side of the outer wall of the second connecting shaft, and a protective plate is fixedly connected to the top surface of both the first support frame and the second support frame.
