Description
Technical Field
The utility model relates to the field of building equipment, in particular to a prefabricated floor slab unidirectional plate closely spliced node structure.
Background
The prefabricated floor slab is a concrete prefabricated member produced and formed in a prefabricated field and is directly transported to a construction site for installation. Prefabricated slabs are floors used in the construction of early 20 th century, and are modules or slabs used in engineering. Because the prefabricated concrete member is produced and formed in the prefabricated field, the prefabricated concrete member is directly transported to a construction site for installation. When the prefabricated plate is manufactured, the hollow model is firstly nailed by the wood plate, the hollow part is filled with cement after the reinforcing steel bars are distributed in the hollow part of the model, the wood plate is knocked out after the hollow part is dried, and the rest is the prefabricated plate. Prefabricated panels are used in many applications in construction, such as cement panels covered by ditches beside roads, and cement panels with insulation on roofs are prefabricated panels. The prefabricated floors are often provided with gaps when being installed, but the existing sealing method is to simply pour cement, so that the method is difficult to ensure the connection tightness between the prefabricated floors and influence the quality of a building.
Disclosure of Invention
The utility model mainly solves the technical problem of providing the unidirectional plate closely spliced node structure of the precast floor slab, which can ensure that the concrete connection of the unidirectional plate closely spliced node of the precast floor slab is more sealed and compact, and ensure the quality of a building.
In order to achieve the above object, the present utility model provides the following technical solutions:
the one-way plate close-spliced node structure of the precast floor slab comprises two precast floor slabs which are spliced with each other, the close end parts of the two precast floor slabs are respectively provided with a detail structure, reinforcing ribs and distributing ribs which are distributed vertically to each other are arranged inside the precast floor slabs, gaps (La is the anchoring length of the distributing ribs of the floor slab) with the length of 0.8La+20mm are reserved at close-spliced ends, the thickness is h-60mm (namely the thickness of the floor slab minus 60 mm), reinforcing ribs on the upper parts of the precast floor slabs on two sides extend out to be overlapped, the overlapping length is 1.6La, and reinforcing ribs with the length of 1.6La are placed at the bottoms of the gaps (the specification and the spacing of the reinforcing ribs are equal to those of the distributing ribs of the floor slab).
As a further optimization of the technical scheme, the gap end part of the precast floor slab is provided with a detail structure with the size of 20 multiplied by 20 mm.
As a further optimization of the technical scheme, the precast floor slabs are all constructed by reinforced concrete.
As a further optimization of the technical scheme, the reinforcing ribs are all made of carbon structural steel bars.
As a further optimization of the technical scheme, the distribution bars are all made of carbon structural steel bars.
The beneficial effects of adopting above technical scheme are: this close node structure of piecing together of prefabricated floor one-way board leaves the breach at close end of piecing together, and the inside strengthening rib and the distribution muscle that are equipped with mutually perpendicular and distribute of prefabricated floor, and prefabricated floor upper portion reinforcing bar in both sides stretches out and overlap joint, places the strengthening rib in breach bottom. The end part of the gap of the precast floor slab is provided with a 20X 20mm detail structure for ensuring the compactness of concrete at the joint. Therefore, the concrete connection of the unidirectional plate closely spliced nodes of the precast floor slabs can be ensured to be more sealed and compact, and the quality of a building is ensured.

FIG. 1 is a schematic structural view of a one-way plate closely spliced node structure of a precast floor slab;
fig. 2 is a schematic structural view of the detailed construction shown in fig. 1.
Wherein, 1-precast floor slab, 2-detail structure, 3-reinforcing rib and 4-distributing rib.
Detailed Description
The following describes in detail the preferred embodiments of the prefabricated floor slab unidirectional plate closely spliced node structure according to the present utility model with reference to the accompanying drawings.
Fig. 1 and 2 show a specific embodiment of the one-way plate closely spliced node structure of the prefabricated floor slab:
with reference to fig. 1 and 2, the one-way slab close-spliced node structure of the precast floor slab comprises two precast floor slabs 1 which are spliced with each other, the close end parts of the two precast floor slabs 1 are respectively provided with a detail structure 2, reinforcing ribs 3 and distributing ribs 4 which are distributed vertically to each other are arranged inside the precast floor slabs, gaps with the length of 0.8La+20mm (La is the anchoring length of the distributing ribs 4 of the floor slab) are reserved at close-spliced ends, the thickness is h-60mm (namely, the thickness of the floor slab is minus 60 mm), reinforcing steel bars on the upper parts of the precast floor slabs 1 are stretched out for lap joint, the lap joint length meets 1.6La, and reinforcing ribs 3 with the length of 1.6La are placed at the bottoms of the gaps (the specification and the spacing of the reinforcing ribs 3 are identical to those of the distributing ribs 4 of the floor slab).
The notched end of the precast floor slab 1 has a detail formation 2 of 20 x 20mm in size. The precast floor slabs 1 are all built by reinforced concrete, are firm and durable and are easy to model. The reinforcing ribs 3 are all made of carbon structural steel bars, and have high hardness and good toughness. The distributing ribs 4 are all made of carbon structural steel bars, and have high hardness and good toughness.
This close node structure of piecing together of prefabricated floor one-way board leaves the breach at close end of piecing together, and prefabricated floor 1 inside is equipped with perpendicular distribution's reinforcement 3 and distribution muscle 4, and the reinforcement stretches out on prefabricated floor 1 upper portion of both sides and carries out the overlap joint, places reinforcement 3 in the breach bottom. The 20X 20mm detail structure 2 is arranged at the end part of the gap of the precast floor slab 1 and used for ensuring the compactness of concrete at the joint. Therefore, the concrete connection of the unidirectional plate closely spliced nodes of the precast floor slabs can be ensured to be more sealed and compact, and the quality of a building is ensured.
