Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] refer to figure 1 , figure 2 , the invention discloses an environmentally friendly construction method for prefabricated concrete floor slabs, which includes the following construction steps:

[0038] S1. Prepare concrete for floor slabs: Put cement, water, fine-grained coal gangue, blast furnace slag powder, cement quick-setting agent, defoamer, and water-reducing agent into the concrete mixer. 2-4mm, the defoaming agent is a silicone defoaming agent, the weight parts of each raw material input are 16:22:11:3.5:0.015:0.065:0.25, that is, the concrete for the floor slab is ready for use;

[0039] S2, install the floor slab pouring formwork 2: the cavity 14 for pouring the prefabricated floor slab 10 is composed of the bottom surface formwork 1, the pouring formwork 2 on the left side, the pouring formwork 2 on the right side, the pouring formwork 2 on...

Abstract

The invention relates to an environmentally friendly construction method for prefabricated concrete floor slabs, which includes the following construction steps: S1, preparing concrete for floor slabs: mixing cement, water, fine-grained coal gangue, blast furnace slag powder, cement accelerator, disinfectant Foaming agent and water reducing agent are put into the concrete mixer together to get concrete for floor slab for use; S2, install floor slab pouring formwork; S3, pour concrete for floor slab; S4, assemble prefabricated floor slab and load-bearing wall; S5, fixed prefabricated floor slabs. The bottom formwork and pouring formwork of the present invention can be recycled and applied to pouring prefabricated concrete floor slabs, the floor slab and the load-bearing wall are matched and assembled more reasonably, and the construction process of the entire floor slab is environmentally friendly and energy-saving.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an environmentally friendly construction method for a prefabricated assembled concrete floor slab. Background technique [0002] The prefabricated reinforced concrete floor slab refers to the reinforced concrete floor slab that is prefabricated outside the component prefabrication processing plant or the construction site, and then transported to the construction site for installation. Among them, most of the prefabricated reinforced concrete floor slabs adopt the structure of circular hole slabs and channel slabs. Generally, steel bars are provided at the ends of the slabs. After on-site assembly, the joints are filled with concrete to strengthen the integrity. The prefabricated reinforced concrete floor slabs using round hole plates and grooved plates are prone to cracking of the round holes and deformation of the groove shape after long-term use, which will br...
