Abstract
The invention belongs to the field of civil engineering, and relates to a fully-assembled sunken floor slab and a connection structure thereof. The fully-assembled sunken floor slab comprises precast concrete slabs and connecting steel plates, wherein the side faces of the four sides of each precast concrete slab are embedded with the outwards-extending connecting steel plates, the connecting steel plates are positioned in the middle of the side faces of the precast concrete slabs, and one ends of the connecting steel plates, extending out of the precast concrete slabs, are connected with the upper flanges of the H-shaped steel beams through connecting bolts. The bending moment at the plate end of the precast concrete plate is transmitted to the H-shaped steel beam through the connecting steel plate and the bolt, and the force transmission path is short and definite; the connecting steel plate and the bolts have high strength and rigidity, so that the safety and reliability of the connection between the beam and the plate can be ensured; the connecting steel plate is positioned at the middle position of the plate side, so that the total height of the beam plate is effectively reduced, and the indoor clear height is increased. In addition, the fully-assembled sinking floor type plate is connected with the H-shaped steel beam through the bolts, so that on-site welding is avoided, and the assembly construction efficiency is improved.
Description
Technical field
The invention belongs to field of civil engineering, are related to a kind of assembly sunk type floor and its connecting structure entirely.
Background technology
Industrialization and urbanization are the bases of modernization, and assembled architecture is the important component of building industrialization；
Meanwhile assembled architecture is the Major Strategic Demand for promoting housing industrialization transition and upgrade, dissolving present steel excess capacity.Dress
There is the characteristics of building element standardized designs, batch production processing, fabricated construction with formula building, advantageously reduce construction and cause
Environmental pollution, shorten construction period, use manpower and material resources sparingly.In recent years, country is greatly developing assembled architecture industry, pushes away
Dynamic mode of construction innovation.
Floor is the main horizontal member in building structure, and sizable proportion is occupied in whole building structure.It is existing
Some assembled floors have assembled integrals floor and the concretes such as steel bar truss floor support plate, precast concrete superimposed sheet
The full assembled floor such as native T plate, steel skeleton light-duty floor support plate.Construction of the existing assembled floor in the junction of beam and plate
Floor is placed in top surface of the beam or more and is attached by way, such beam slab connecting structure way makes the beam slab of assembled floor total
It is highly larger, reduce interior net storey height.In addition, the use that way of the existing assembled floor in beam Yu plate junction has is reserved
Bar Anchorage, the way that live formwork pours, some uses built-in connection in prefabricated board, the way of site welding.Scene
Formwork pours or the way of site welding causes construction speed to extend, and reduces floor prefabricated construction efficiency.
Invention content
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide, a kind of construction efficiency is high, and beam slab total height is low, knot
Structure safe and reliable full assembly sunk type floor and its connecting structure.
Technical scheme of the present invention：A kind of full assembly sunk type floor, it is complete assemble sunk type floor by precast slab,
Junction steel plate forms, and four flank side surface of precast slab is embedded with overhanging junction steel plate, and junction steel plate is located at concrete
Native plate side centre position, one end that junction steel plate stretches out precast slab pass through the top flange of connection bolt and H profile steel beam
Connection.
Preferably, the piece gap between satisfactory to both parties assembly sunk type floor is concrete.
Beneficial effects of the present invention：The pre-buried overhanging junction steel plate in plate side centre position of precast slab connects steel
Plate external part is bolted with H profile steel beam.The plate end moment of flexure of precast slab is transmitted to H by junction steel plate and bolt
On section steel beam, Path of Force Transfer is short and clear, and plate end moment of flexure can be effectively transmitted on H-type beam.Junction steel plate has with bolt
There are very high intensity and rigidity, can ensure the security reliability that beam is connect with plate.Junction steel plate is located at plate side centre position, has
Effect reduces beam slab total height, increases interior net storey height.In addition, assembly sinking building formula floor is connected by bolt and H profile steel beam entirely
It connects, avoids on-the-spot welding, improve prefabricated construction efficiency.
Description of the drawings
Fig. 1 is the A-A sectional views of the embodiment of the present invention.
Fig. 2 is decomposition diagram before the assembly of the embodiment of the present invention.
Fig. 3 is that the monolithic of the embodiment of the present invention assembles sunk type floor level figure entirely；
Fig. 4 is the floor plan of the embodiment of the present invention under construction；
Specific implementation mode
The present invention will be further described below in conjunction with the accompanying drawings and by embodiment.
Embodiment
A kind of full assembly sunk type floor, the full sunk type floor that assembles are made of precast slab 1, junction steel plate 2, in advance
1 four flank side surface of concrete slab processed is embedded with overhanging junction steel plate 2, and junction steel plate 2 is located among 1 side of precast slab
Position, one end that junction steel plate 2 stretches out precast slab 1 are connect by connecting bolt 3 with the top flange of H profile steel beam 4.Connection
Steel plate external part reserves row's bolt hole 5, and the reserved two rows of bolt holes 6 of 4 top flange corresponding position of H profile steel beam connect bolt 3
Be made of nut 7 and bolt 8, nut 7 is located at the top of junction steel plate 2, and bolt 8 is located at the lower part of 4 top flange of section steel beam, plate with
9 fill concrete of piece gap of plate.
