Therefore, in order to solve the above problems, a connection structure of an assembled composite floor slab and a cast-in-place beam is required to solve the above problems.
Disclosure of Invention
In view of this, the connection structure of the technical scheme can realize that the composite floor slab is quickly hoisted in place at a construction site, avoids collision between reserved anchor steel bars of the composite floor slab and a cast-in-place beam, and solves the problem that the reserved anchor steel bars of the composite floor slab are difficult to install.
A connection structure of an assembled composite floor slab and a cast-in-place beam comprises the cast-in-place beam arranged in a cast-in-place beam template and the composite floor slab connected with the cast-in-place beam in a pouring mode; the cast-in-place roof beam both sides extend outward and are formed with and choose the ear, it is used for with coincide floor cooperation use annular stirrup to choose to install on the ear.
Furthermore, be provided with the vertical strengthening rib of perpendicular to annular stirrup place plane in the annular stirrup, vertical strengthening rib arranges between choosing ear and annular stirrup.
Further, be provided with in the coincide floor and reserve the anchor reinforcing bar, it is provided with the horizontal locating hole that uses with reserving the anchor reinforcing bar cooperation in the ear to choose.
Furthermore, the composite floor slab is arranged on the cast-in-place beam template, and the reinforced concrete composite layer is poured on the composite floor slab.
And further, a floor concrete layer is arranged on the reinforced concrete superposed layer and the annular stirrups, and reinforcing transverse ribs are arranged in the floor concrete layer.
Further, still include the support frame, cast-in-place roof beam template is installed on the support frame.
The invention has the beneficial effects that: the connection structure of the technical scheme can realize that the composite floor slab is quickly hoisted in place at a construction site, avoids collision between reserved anchor steel bars of the composite floor slab and a cast-in-place beam, solves the problem that the reserved anchor steel bars of the composite floor slab are difficult to install, and because of the arrangement of the longitudinal reinforcing ribs and the annular stirrups at the ear parts, the corner cut at the beam column joint is not needed when the composite floor slab is divided, the composite floor slab split by adopting the method is a regular rectangle, the production and construction efficiency of the composite floor slab is improved, and the stress performance of the connection node of the composite floor slab and the cast-in-place beam is ensured to be reliable.
Drawings
The invention is further described below with reference to the following figures and examples:
fig. 1 is a schematic view of the overall structure of the present invention.
Detailed Description
FIG. 1 is a schematic view of the overall structure of the present invention; as shown in the figure, the connection structure of the assembled composite floor slab and the cast-in-place beam comprises a cast-in-place beam 1 installed in a cast-in-place beam template 2 and a composite floor slab 5 connected with the cast-in-place beam 1 in a pouring mode; the cast-in-place roof beam 1 both sides are outwards extended and are formed with and choose ear 3, choose to install on the ear 3 and be used for the annular stirrup 6 that uses with 5 cooperations of coincide floor, this technical scheme's joint construction can realize that the coincide floor hoists fast in the job site and takes one's place, avoid the coincide floor to reserve anchor reinforcing bar and cast-in-place roof beam collision, the difficult problem of the difficult installation of coincide floor reservation anchor reinforcing bar has been solved, owing to choose the setting of ear department vertical strengthening rib and annular stirrup, the coincide floor need not to carry out the corner cut in beam column junction when dividing, the coincide floor that adopts this method split is the rectangle of rule, improve coincide floor production and efficiency of construction, guaranteed coincide floor and cast-in-place roof beam connected node atress performance reliable.
In this embodiment, a longitudinal reinforcing rib 4 perpendicular to a plane where the annular stirrup 6 is located (i.e., a rectangular cross section of the annular stirrup 6 in fig. 1) is disposed in the annular stirrup 6, and the longitudinal reinforcing rib 4 is disposed between the overhanging lug 3 and the annular stirrup 6. The arrangement of the annular stirrups 6 ensures the installation strength of the ear and the composite floor slab, ensures the stress stability, the arrangement of the longitudinal reinforcing ribs 4 ensures that the whole structure is structurally reinforced in the transverse direction and the longitudinal direction, the whole performance is improved, and after the composite floor slab 5 is installed in place, the longitudinal reinforcing ribs 4 are fixedly bound in place.
In this embodiment, be provided with in the coincide floor 5 and reserve anchor reinforcing bar 53, it is provided with the transverse orientation hole that uses with reserving anchor reinforcing bar 53 cooperation in the ear to choose. Choose ear tip to be provided with transverse orientation hole, carrying out the alignment installation of coincide floor, only need will reserve anchor reinforcing bar 53 and insert transverse orientation downthehole, can realize quick location installation.
