Embodiment Construction

[0032] The prefabricated concrete member of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0033] The prefabricated concrete element according to the invention is characterized in that one or more longitudinal concrete slabs protrude laterally, and the concrete slabs are perforated. figure 1 It is a schematic diagram of Embodiment 1 of the present invention. A concrete slab 2 protrudes from the side of the prefabricated concrete member 1, and a hole 3 is opened on the concrete slab 2. The thickness of the concrete slab 2 is smaller than the thickness of the precast concrete member 1, the length and quantity of the concrete slab are determined according to the requirements of force, production and construction; the size and spacing of the holes are determined according to the requirements of force, production and construction, so that it can The post-cast concrete inside locks together. The hole 3 can be ...

Abstract

The invention relates to a precast concrete member and belongs to the technical field of precast concrete structures. One or more longitudinal concrete plates extend out from the side face of the precast concrete member. Holes are formed in the concrete plates. The reliability of connecting of concrete structure members can be improved, the industrialization level of a building structure is improved, and resources are saved.

Description

technical field [0001] The invention belongs to the technical field of prefabricated reinforced concrete structures, in particular to a prefabricated concrete structural member. Background technique [0002] In the construction process of cast-in-place reinforced concrete structures, there are many on-site fabrications, many wet operations, and a large number of intermediate links such as formwork projects and scaffolding projects, which waste resources and pollute the environment; issues of performance, quality and durability. To change the status quo, we should vigorously develop prefabricated concrete structures, reduce the amount of on-site concrete structures, and increase the rate of prefabrication. The main structural components of prefabricated concrete structures are manufactured in factories, which have high production efficiency and good quality, save resources and energy, and are conducive to sustainable development. The use of prefabricated concrete structures...
