Description

Prefabricated floor one-way slab dense joint structure

technical field

The invention relates to the field of construction equipment, in particular to a prefabricated floor one-way slab dense joint structure.

Background technique

Prefabricated floor slabs are concrete prefabricated parts produced and processed in the prefabrication yard, which are directly transported to the construction site for installation. Prefabricated panels are the floor slabs used in the early 20th century buildings, which are the modules or panels used in the project. Because the prefabricated concrete parts are produced and processed in the prefabrication yard, they are directly transported to the construction site for installation. When making prefabricated panels, first use wooden boards to nail the hollow model, and after distributing steel bars in the hollow part of the model, fill the hollow part with cement, knock off the wooden board after it dries, and the rest is the prefabricated board. Prefabricated panels have many uses in construction, such as the cement panels covered on the ditch next to the road, and the cement panels used as the insulation layer on the roof are all prefabricated panels. There are often gaps between the prefabricated slabs during installation, but the existing sealing method is simply pouring cement. This method is difficult to ensure the sealing of the connection between the prefabricated slabs, which affects the quality of the building.

Contents of the invention

The technical problem mainly solved by the present invention is to provide a prefabricated floor one-way slab dense joint structure, which can ensure that the concrete connection of the one-way slab close joint joints of the prefabricated floor is more sealed and tight, and the quality of the building is guaranteed.

To achieve the above object, the present invention provides the following technical solutions:

The prefabricated slab one-way slab joint structure includes two prefabricated slabs that are combined with each other. The dense ends of the two prefabricated slabs are equipped with detailed structures. A gap of 0.8La+20mm is left at the end (La is the anchorage length of the distributed reinforcement of the floor), and the thickness is h-60mm (that is, the thickness of the floor minus 60mm). A reinforcing rib with a length of 1.6La is placed at the bottom of the gap (the specification and spacing of the reinforcing ribs are equal to the distribution ribs of the floor).

As a further optimization of the technical solution, the notch end of the prefabricated floor slab has a detailed structure with a size of 20×20 mm.

As a further optimization of the technical solution, the prefabricated floors are all constructed of reinforced concrete.

As a further optimization of the technical solution, the reinforcing bars are all made of carbon structural steel bars.

As a further optimization of the technical solution, the distribution bars are all made of carbon structural steel bars.

The beneficial effect of adopting the above technical scheme is that: the one-way slab joint structure of the prefabricated slab leaves a gap at the close joint end, and the interior of the prefabricated floor is provided with reinforcing ribs and distribution ribs distributed perpendicularly to each other, and the upper reinforcement bars of the prefabricated slabs on both sides protrude out. Lap splicing, placing reinforcing ribs at the bottom of the gap. A 20×20mm detail structure is provided at the notch end of the prefabricated floor slab to ensure that the concrete at the joint is dense. In this way, the concrete connection of the one-way slab dense joint joints of the prefabricated floor slabs can be guaranteed to be more tightly sealed and the quality of the building can be guaranteed.

Detailed ways

The preferred implementation of the one-way slab dense joint structure of the prefabricated floor slab of the present invention will be described in detail below in conjunction with the accompanying drawings.

Figure 1 and Figure 2 show the specific implementation of the one-way slab dense joint structure of the prefabricated floor:

Combining Figures 1 and 2, the one-way slab joint structure of the prefabricated slabs includes two prefabricated slabs 1 that are combined with each other, and the dense ends of the two prefabricated slabs 1 are provided with detailed structures 2. Reinforcing ribs 3 and distribution ribs 4, leave a gap of 0.8La+20mm in length at the end of close fitting (La is the anchoring length of floor distribution rib 4), the thickness is h-60mm (that is, the floor thickness minus 60mm), and the upper part of prefabricated floor 1 on both sides The steel bars are stretched out for lapping, and the lapping length meets 1.6La, and a reinforcing bar 3 with a length of 1.6La is placed at the bottom of the gap (the specification and spacing of the reinforcing bars 3 are equal to those of the floor distribution bars 4).

The notched ends of the prefabricated floor slabs 1 have details 2 of dimensions 20×20 mm. The prefabricated floor slabs 1 are all made of reinforced concrete, which is durable and easy to shape. The reinforcing ribs 3 are all made of carbon structural steel bars, which have high hardness and good toughness. The distribution bars 4 are all made of carbon structural steel bars, with high hardness and good toughness.
