Above -mentioned reinforced concrete roof beam can make concrete and the cohesion between the beam manufacturing is great in advance, and bonding strength between the two is higher.
Description
Technical field
The utility model is related to beam column technical field, more particularly to a kind of reinforced beam.
Background technology
At present, it is that integral cast-in-situ is formed with beam column major part between floors.This cast-in-place beam column, scene needs to tie up
Wire-tie, on a large scale the work such as formwork, loaded down with trivial details, complex procedures of constructing, the amount of labour is big, wastes time and energy.
Utility model content
Based on this, it is necessary to provide a kind of reinforced beam, operation is enabled to simply, construction is easy, and and coagulation
The adhesion of soil is larger.
A kind of reinforced beam, including precast beam and prefabricated board, pour mixed on the precast beam and the prefabricated board
Solidifying soil；The precast beam generally rectangular structure；Steel bar stress is embedded with the precast beam, the precast beam top is arranged
There is stirrup；One end at the top of the precast beam offers inverted T-shaped groove；The side wall of the groove is on-plane surface.
In one embodiment, the steel bar stress is arranged on the inverted T-shaped groove downside, the side wall of the inverted T-shaped groove
Two ends are provided with built-in fitting.
In one embodiment, the precast beam is internally provided with hollow storehouse, and the hollow storehouse and the inverted T-shaped groove point
Not Wei Yu the precast beam two ends.
In one embodiment, the hollow storehouse is domes.
In one embodiment, the number in the hollow storehouse is one or two.
In one embodiment, the side wall of the inverted T-shaped groove is zigzag curved surface or wavy curved surface.
In one embodiment, the inverted T-shaped groove has side wall, bottom surface and skew wall face；The side wall and the bottom
Connected by the skew wall face between face；There is default angle between the skew wall face and the bottom surface.
In one embodiment, the steel bar stress is the level Four screw-thread steel of HRB500.
In one embodiment, the built-in fitting is the level Four screw-thread steel of HRB500.
Above-mentioned reinforced beam, including precast beam and prefabricated board.The casting concrete on precast beam and prefabricated board, it is prefabricated
The one end in back portion offers inverted T-shaped groove, and the side wall of inverted T-shaped groove is on-plane surface.Afterwards during pouring concrete, concrete can fill
Space shared by full inverted T-shaped groove.Due to inverted T-shaped groove side wall be on-plane surface, therefore concrete setting after with precast beam
Between adhesion it is larger, bond strength between the two is higher.
Description of the drawings
Fig. 1 is the dimensional structure diagram in the utility model reinforced beam one embodiment；
Fig. 2 is the front view of Fig. 1；
Fig. 3 is the left view of Fig. 2.
Specific embodiment
To make the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing to this practicality
The specific embodiment of novel reinforced concrete beam is illustrated.It should be appreciated that specific embodiment described herein is only used
To explain the utility model, it is not used to limit the utility model.
Referring to Fig. 1 and Fig. 2, in one embodiment, reinforced beam can include precast beam 100 and prefabricated board, and (figure is not
Show).The casting concrete on precast beam 100 and prefabricated board.The generally rectangular structure of precast beam 100.It is embedded with precast beam
Steel bar stress 200.The top of precast beam 100 is provided with stirrup 300.The one end at the top of precast beam 100 offers inverted T-shaped groove 400.
The side wall of inverted T-shaped groove 400 is on-plane surface.
In rear pouring concrete, concrete can be full of the space shared by inverted T-shaped groove 400.Due to inverted T-shaped groove 400
Side wall is bigger with the adhesion between precast beam 100 after on-plane surface, therefore concrete setting, bond strength between the two
It is higher.
Preferably, steel bar stress 200 can be arranged on the downside of inverted T-shaped groove 400.The side wall two ends of inverted T-shaped groove 400
Built-in fitting 500 is provided with, can further increase the cohesive force between precast beam 100 and concrete.
Referring to Fig. 3, in one embodiment, hollow storehouse 600 can be provided with inside precast beam 100.The energy of hollow storehouse 600 is set
Enough mitigate the weight of precast beam 100.Hollow storehouse 600 is shaped as arch.The stress-bearing capability of hollow storehouse 600 for being shaped as arch is relative
Stress-bearing capability in cubical hollow storehouse is higher.Wherein, the number in hollow storehouse 600 can be one or two, but be difficult
It is many.And hollow storehouse 600 and inverted T-shaped groove 400 are respectively positioned at the two ends of precast beam 100.
Referring to Fig. 2, in one embodiment, the side wall 401 of inverted T-shaped groove 400 is zigzag curved surface.Inverted T-shaped groove 400
With side wall 401, bottom surface 402 and skew wall face 403.Connected by skew wall face 403 between side wall 401 and bottom surface 402.Inclined-plane
There is default angle between 403 and bottom surface 402.
In addition, steel bar stress 200 and built-in fitting 500 can be the level Four screw-thread steel of HRB500.
Above-mentioned reinforced beam, is set to on-plane surface, the energy in rear pouring concrete by the side wall of inverted T-shaped groove 400
Enough increase the adhesion between concrete and precast beam 100.And arranging hollow storehouse 600 can mitigate the weight of precast beam 100.And
And above-mentioned reinforced beam is precast beam, therefore easy construction, operation is simple.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more concrete and detailed,
But therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that common for this area
For technical staff, without departing from the concept of the premise utility, some deformations and improvement can also be made, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be defined by claims.
