Prefabricated foundation assembly and splicing method thereof

Abstract

The invention discloses a prefabricated foundation assembly which comprises at least two bases and a connecting transverse beam, wherein the at least two bases are arranged on the ground; the connecting transverse beam is used for connecting the adjacent bases; a steel structure module is fixedly arranged above each base; embedded screw studs are arranged at the upper top surface of each base; a connecting end plate is fixedly arranged at the bottom end part of each steel structure module; and connecting holes matched with the embedded screw studs are formed in the connecting end plate. Meanwhile, the invention also discloses a splicing method of the prefabricated foundation assembly. The bases and the connecting transverse beam are manufactured in advance in a prefabrication factory; during installation, all the bases are connected through the connecting transverse beam; and then, the steel structure module is arranged on each base. The pouring in a construction site is not needed; the fast splicing can be realized in the construction site; the construction period is shortened; and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a prefabricated foundation component and an assembly method thereof. Background technique [0002] At this stage, the foundation of the main control building of the substation mostly adopts the wet operation method of on-site pouring. Due to the influence of various factors such as personnel quality, climate, surrounding environment, and environmental protection, the current cast-in-place foundation has problems in the process of construction and use. There are many disadvantages, for example, the foundation is heavy and its bearing capacity and earthquake resistance are low, construction quality is difficult to control, the construction period is long, and the cost is high. At the same time, it is difficult to meet the requirements of civilized construction, energy saving, and environmental protection, which will directly affect the safety of the foundation. , durabi...

Problems solved by technology

[0002] At this stage, the foundation of the main control building of the substation mostly adopts the wet operation method of on-site pouring. Due to the influence of various factors such as personnel quality, climate, surrounding environment, and environmental protection, the current cast-in-place foundation has problems in the process of construction and use. There are many disadvantages, for example, the foundation is heavy and its bearing capacity and earthquake resistance are low, construction quality is difficult to control, the construction period is long, and the cost is high. At the same time, it is difficult to meet the requirements of civilized construction, energy saving, and environmental protection, which will directly affect the safety of the foundation. , durability and economy

[0003] With the rapid development of substation construction in my country, higher requirements are put forward for the construction quality, construction period, project investment, energy conservation and environmental protection of civil engineering, and the traditional wet operation method restricts the rapid development of substation construction.

Moreover, power production overhaul, technical renovation projects and other projects must meet the reliability requirements of power supply, and the power outage time should be shortened as much as possible. Therefore, the cast-in-place foundation is not suitable for overhaul and technical renovation projects that have very strict construction schedules.
