Specific implementation mode
The feature of the present invention and other correlated characteristics are described in further detail by embodiment below in conjunction with attached drawing, with
Convenient for the understanding of technical staff of the same trade：
Picture 1-4, label 1-10 is respectively in figure：T plate 1, horizontal top 2, T-type plate 3, end-thickened section 4, horizontal reinforcing
Muscle 5, vertical reinforcement net 6, oblique rinforcement bar 7, horizontal mesh reinforcement 8, presstressed reinforcing steel 9, lifting built-in fitting 10.
Embodiment：As shown in Figs 1-4, the present embodiment be specifically related to a kind of anti-slit formation prestressing force T plate 1, to end into
Row thickeies and setting reinforced steel, and solving thin-walled top board structure while not increasing by 1 weight of T plate is also easy to produce asking for crack
Topic.
As shown in Figs 1-4, a kind of anti-slit formation prestressing force T plate 1, including horizontal top 2 and two T-type plates 3, T-type plate 3
The bottom for being set to horizontal top 2 of vertical symmetry, and T-type plate 3, along the horizontal top longitudinally elongated setting, it is in " π " to be formed
The structure of shape.It is provided in thicken end-thickened section 4, end-thickened section 4 of two end sets of horizontal top 2 and T-type plate 3
Reinforced steel.The upper surface of horizontal top 2 is horizontal, and end-thickened section 4 of thickness linearly thickeies, and end-thickened section 4 is leaned on
The side of the end of nearly horizontal top 2 is to thicken maximum, and region of the horizontal top 2 other than end-thickened section 4 can be used thin
Wall construction.Two 3 length of T-type plate are identical as horizontal top 2, and setting direction is parallel with the side of T-type plate 3.Horizontal top 2 with
T-type plate 3 forms integral structure by concreting.The upper surface of horizontal top 2 is symmetrically provided with multiple lifting built-in fittings
10, mechanical equipment lifts built-in fitting 10 by connection and realizes the transport of T plate 1 and mobile operation.End-thickened section 4 of thickness by
The length of T plate 1 determines.It is gradually thickeied to edge most from 2 inside of horizontal top by the way of linearly thickening for end-thickened section 4
At thickness, the weight of a part, while the mechanical structure that its amplitude of variation is smaller can be reduced while realizing end resistance to stress
Also the generation in crack can be prevented.Horizontal top 2 increases the thickness of two ends in end-thickened section 4 of two end sets,
The influence of temperature stress can be effectively overcome in casting process.
As shown in Figs 1-4, longitudinally disposed therealong in horizontal top 2 to have horizontal mesh reinforcement 8, it is disposed with vertical steel in T-type plate 3
Muscle net 6.Two groups of reinforced steels are vertically arranged in each end-thickened section 4, every group of reinforced steel includes being located at same erect
Horizontal reinforcing muscle 5 in straight plane and oblique rinforcement bar 7.
Oblique 7 inclined posture of rinforcement bar is set to the connection corner of T-type plate 3 and horizontal top 2, under oblique rinforcement bar 7
End is connected with vertical reinforcement net 6, upper end same level bar-mat reinforcement 8 and horizontal reinforcing muscle 5 are connected.The upper end of oblique rinforcement bar 7
It is directed toward the centerline direction of horizontal top 2.Horizontal reinforcing muscle 5 includes upper horizontal reinforcing muscle 5 and lower horizontal reinforcing muscle 5, upper level
Rinforcement bar 5 is respectively arranged at lower horizontal reinforcing muscle 5 above and below horizontal mesh reinforcement 8.Horizontal reinforcing muscle 5 is not limited to two
It is a, it should be increased according to the thickness of practical T plate 1.
Horizontal mesh reinforcement 8 and vertical reinforcement net 6 are the main body frameworks for constituting T plate 1, are propped up 1 overall structure of T plate
Support, further provides additional auxiliary force by oblique rinforcement bar 7 and horizontal reinforcing muscle 5 and overcomes hoisting transportation process and casting process
In due to asking in the crack at end check of the discontinuity between T-type plate 3 and horizontal top 2 and horizontal top 2 middle part
Topic.Presstressed reinforcing steel 9 is set in the lower part of T-type plate 3, there are precharge pressures to 3 structure of T-type plate, to improve the carrying of T plate 1
Power.Horizontal reinforcing muscle 5 reinforces end-thickened section 4 of horizontal top 2, improves end shearing resistance and the ability of torsion, keeps away
Exempt from influence of the stress to end thick section 4, reduces the possibility in the crack that 2 middle part of horizontal top generates.Oblique rinforcement bar 7 is by water
Flat rinforcement bar 5, vertical reinforcement net 6, horizontal mesh reinforcement 8, which are sequentially connected, to be avoided pouring and tears work caused by stress in transportational process
With the influence for T plate 1, reduce the possibility in the crack of 1 end of T plate generation.The angle of inclination control of oblique rinforcement bar 7
Between 30 ° to 50 °, suitable for using 40 ° of angle of inclination, there are preferable stability.The length of oblique rinforcement bar 7 adds with end
The thickness of thick section 4 is associated with, and is also associated with end-thickened section 4 with 2 angle of inclination of horizontal top.Each steel involved in reinforced steel
The diameter of muscle is associated with above-mentioned end-thickened section 4 of thickness, and under normal circumstances, the diameter of the bigger reinforcing bar of thickness accordingly increases.
Above-mentioned horizontal mesh reinforcement 8, vertical reinforcement net 6, and phase is tiltedly realized by steel wire lashing between rinforcement bar 7, horizontal reinforcing muscle 5
Mutual connection status.
The advantages of the present embodiment is：By to the end-thickened ability for improving end shearing resistance and torsion of horizontal top 2, preventing
Only the ability in crack occurs for 1 end of T plate；End shearing resistance and the ability of torsion are further increased by reinforced steel, it is less
The influence of stress in casting process；Simple structure, easy to process, strong applicability.
