Light-weight, energy-saving and environment-friendly prefabricated floor slab and installation process thereof

Abstract

The invention provides a light-weight, energy-saving and environment-friendly prefabricated floor slab. The floor slab comprises a plurality of bamboo layers and concrete layers by which the bamboo layers are wrapped, bamboo rods between two adjacent bamboo layers are vertical to each other, bamboo stirrups are fixed on two sides of each bamboo rod which is arranged at the even-numbered bamboo layer, and the bamboo stirrups encircle each bamboo rod which directly faces the odd-numbered bamboo layer in the vertical direction; the concrete layers which are arranged on the left or / and right side(s) of the prefabricated floor slab are provided with first horizontal connective grooves from beginning to end along the length direction of the bamboo rods on the odd-numbered bamboo layers, and the concrete layers on the bottom surface of the prefabricated slab, which are 10-40cm away from the front and rear end faces of the prefabricated slab, are provided with second horizontal connective grooves from beginning to end along the length direction of the bamboo rods on the even-numbered bamboo layers; and the first horizontal connective grooves are connected with vertical material injecting grooves, and the tops of the second horizontal connective grooves are connected with vertical material injecting pipes. According to the prefabricated floor slab provided by the invention, the hollow structures of the bamboo rods are utilized to enable the floor slab to have the effects of light weight, thermal insulation, sound insulation and shock resistance, and connective columns can be formed at joints not only between slabs but also between a slab and a beam through the grooves arranged in the end face and bottom surface of the prefabricated floor slab and matching with a concrete grouting pump.

Description

technical field [0001] The present invention relates to a building board, in particular to a building prefabricated board which is directly transported to the construction site for installation after being processed in a factory, and more particularly relates to a prefabricated floor board which is light in weight, energy-saving, environment-friendly and can be used as a house floor board . The present invention also relates to an installation process for the connection between the prefabricated floor slab itself and the floor slab, and between the floor slab and the frame beam of the house. Background technique [0002] At present, the reinforced concrete floor slabs used in China include cast-in-place floor slabs and prefabricated floor slabs. The cast-in-place floor slabs have good integrity, but they need to be molded on site, and then concrete is poured. The construction period is long and difficult, and the loss of formwork is high.

Problems solved by technology

[0002] At present, the reinforced concrete floor slabs used in China include cast-in-place floor slabs and prefabricated floor slabs. The cast-in-place floor slabs have good integrity, but they need to be molded on site, and then concrete is poured. The construction period is long and difficult, and the loss of formwork is high. On-site formwork is required, the construction period is short, and the cost is low. However, the prefabricated components are heavy and difficult to lift. Cracks are prone to occur at the splicing parts of the components, and the integrity is poor.

In order to reduce the weight of the components, some floors use hollow prefabricated slabs, but the strength of these hollow prefabricated slabs is often not enough. In order to strengthen the integrity of the connection between the floors, the commonly used method is to laminate the floors, although the floors of the laminated floors The integrity of the composite layer is good, but at the joints between the prefabricated slabs, the connection between the cast-in-place concrete and the prefabricated slabs is usually not reliable, and the integrity is still poor

The Chinese patent application with the application number 201510593349.5 and titled "Construction method of prefabricated slab connection node and laminated prefabricated slab" discloses a prefabricated slab connection node, which includes a first prefabricated slab and a connection with the first prefabricated slab. The second prefabricated slab, a connector is provided at the junction of the first prefabricated slab and the second prefabricated slab. The surface and the connecting node between the two are integrated by cast-in-place concrete; although this connecting node can greatly improve the integrity and seismic performance of the prefabricated split floor slab, the steel skeleton needs to be made separately, and the connection between the two prefabricated slabs needs to be It is difficult to control the area of ​​cast-in-place concrete when laying steel skeletons and pouring concrete. In addition, because the skeleton still uses steel bars, and the pollutant discharge from the steel industry is one of the culprits that affect the current air quality, comprehensively strengthen the protection of steel all over the country. Environmental supervision of the industry, in the case of increased penalties, the amount of steel bars should be reduced as much as possible, and more environmentally friendly materials should be used
