Description

Connecting structure of cast-in-place concrete building beam, column and floor slab
Technical Field
The invention relates to the field of concrete buildings, and particularly discloses a connecting structure of a beam, a column and a floor slab of a cast-in-place concrete building.
Background
The existing buildings comprise concrete buildings and steel structure buildings, wherein the concrete buildings comprise a cast-in-place mode and an assembly mode, and the cast-in-place concrete buildings are the most common. One of the building design concepts is that the strong column and the weak beam and the strong shear and weak bending are adopted, namely the stress performance of the column is enhanced, the stress performance of the beam is reduced, when an earthquake comes, the beam end is firstly damaged, the column cannot be damaged, and the integral structure of the building is kept. In the cast-in-place floor slab, because the reinforced concrete is connected with the beam, the column and the beam column node, the stress performance of the beam and the column, especially the stress performance of the reinforced beam, can be enhanced, and the design effect of the strong column and the weak beam can not be realized.
Disclosure of Invention
In view of the above, the present invention provides a connecting structure of a beam, a column and a floor slab of a cast-in-place concrete building, so as to solve the technical problem of the reinforcing effect of the beam by the cast-in-place floor slab.
In order to achieve the purpose, the invention provides the following technical scheme:
the utility model provides a connection structure of cast in situ concrete building roof beam, post and floor, is including setting up weakening the groove on four angles of floor and setting up the reinforcing plate in the cell body, be provided with first connecting hole on the inner wall in weakening the groove, be provided with the second connecting hole on the roof beam, be provided with the cavity of the T font of a plurality of inversions around the reinforcing plate, the cavity includes horizontal part and vertical portion, it is provided with the spliced pole to slide in the horizontal part, the spliced pole can insert in first connecting hole or the second connecting hole, the one side that is close to vertical portion on the spliced pole is provided with first scarf, damping slides in the vertical portion and is provided with first push rod, the bottom of first push rod be provided with first scarf complex second scarf. In this scheme, be provided with the weakening groove on four angles of floor, the effect that weakens the groove is the disconnection floor and is connected with roof beam and post, weakens the atress performance of roof beam, but this atress performance that probably can lead to the floor also descends, brings other potential safety hazards. So be provided with the reinforcing plate in this scheme, be provided with the spliced pole on the reinforcing plate, the spliced pole can insert the second connecting hole of roof beam, weaken in the first connecting hole in groove, so the reinforcing plate can tie-beam and floor, and only can provide the support in vertical direction, can't provide the support in the horizontal direction, improves the support ability of floor to a certain extent. Simultaneously, the mounting means of reinforcing plate is also comparatively simple, places it and weakens in the groove, then inserts first connecting hole and second connecting hole with first push rod, and first push rod can be ejecting with the spliced pole, and the spliced pole just can insert first connecting hole and second connecting hole in, accomplishes the grafting.
Optionally, the spliced pole is provided with hollow horizontal through groove along length direction, the logical inslot damping sliding connection of level has the fixture block, be provided with in the first connecting hole with fixture block complex draw-in groove, be provided with vertical screw along length direction on the first push rod, the bottom of vertical screw extends to the outer wall of second scarf, the horizontal damping sliding connection in bottom of vertical screw has the third push rod, can screw in the bolt in the vertical screw and fix first push rod on the reinforcing plate, and the bolt can promote the third push rod.
Optionally, the connecting column further comprises a second push rod, a sliding block is horizontally arranged at the bottom of the second push rod in a sliding mode, vertical through grooves are vertically formed in the second push rod and the sliding block in a penetrating mode, fixing rods are arranged in the vertical through grooves of the sliding block, and fixing grooves used for inserting the fixing rods are further formed in the first wedge surface of the connecting column. In this scheme, the slider of second push rod can promote the spliced pole at first and outwards remove, and simultaneously, dead lever on the second push rod can be connected with the spliced pole, and when the circumstances such as earthquake take place, roof beam, floor take place the vibration, rock, lead to the spliced pole can take place horizontal migration, roll-off in the second connecting hole of spliced pole follow roof beam this moment, reduce the reinforcing effect to the roof beam.
Optionally, the outer wall of the reinforcing plate is provided with a thin-wall sleeve, a spring is arranged in the thin-wall sleeve and connected with the reinforcing plate, an adjusting hole is formed in the outer wall of the reinforcing plate and communicated with the horizontal portion, a magnet is arranged in one end, close to the center of the reinforcing plate, of the horizontal portion in a sliding mode and can attract the sliding block, a connecting rod is arranged on the magnet and is L-shaped, and one end of the connecting rod stretches into the adjusting hole and abuts against the thin-wall sleeve. In this scheme, when the reinforcing plate received the vibration extrusion, the thin wall cover warp and drive the connecting rod to the inside removal of reinforcing plate, and the connecting rod drives magnet, slider and spliced pole and inwards removes the spliced pole and makes it withdraw from in following the second connecting hole initiatively.
Alternatively, the first push rod is inserted into a vertical portion near the first connection hole, and the second push rod is inserted into a vertical portion near the second connection hole. First push rod inserts can release the spliced pole and insert in the first connecting hole in the vertical portion, and this spliced pole can't withdraw from in the first connecting hole, lead to its unable removal, so be connected between reinforcing plate and the floor firm, and the second push rod inserts in the vertical of second connecting hole, the spliced pole of release can return when the earthquake in the reinforcing plate, the disconnection reinforcing plate is connected with the roof beam, weaken the reinforcing effect of reinforcing plate to the roof beam, better must reach the design effect of strong post weak beam.
Optionally, an internal thread is arranged on the inner wall of the vertical through groove of the second push rod, and a bolt can be screwed into the vertical through groove. The bolt can push the dead lever downwards, makes the dead lever push into in the slider completely.
The working principle and the beneficial effects of the scheme are as follows:
in this scheme, set up the weakening groove in four angles departments of floor, so floor and beam column node do not have the connection completely, have reduced the enhancement effect of floor to the roof beam. In order to increase the stress of the floor slab, prevent water, beautify and safely and the like, the reinforcing plate is arranged in the weakening groove, the connecting columns can extend out of the reinforcing plate, and are inserted into the beam and the floor slab to play a role in indirect connection.
