Specific embodiment
The feature of the utility model and other correlated characteristics are made further specifically by embodiment below in conjunction with attached drawing
It is bright, in order to the understanding of technical staff of the same trade:
Picture 1-4,1-10 is marked to be respectively as follows: T plate 1, horizontal top 2, T-type plate 3, end-thickened section 4, level in figure
Rinforcement bar 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, solves thin-walled top board structure while not increasing by 1 weight of T plate and 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, being formed is in " π "
The structure of shape.Two ends of horizontal top 2 are arranged end-thickened section 4, end-thickened section 4 thickeied and are provided in 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 realizes the transport and mobile operation of T plate 1 by connection lifting built-in fitting 10.End-thickened section 4 of thickness by
The length of T plate 1 determines.It is gradually thickeied to edge most by the way of linearly thickening from 2 inside of horizontal top for end-thickened section 4
At thickness, the weight of a part, while the lesser mechanical structure of its amplitude of variation can be reduced while realizing end resistance to stress
Also the generation in crack can be prevented.Horizontal top 2 is arranged end-thickened section 4 two ends, increases the thickness of two ends,
The influence of temperature stress can be effectively overcome in casting process.
As shown in Figs 1-4, horizontal mesh reinforcement 8 has been arranged along its longitudinal direction in horizontal top 2, 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 and oblique rinforcement bar 7 in straight plane.
The oblique inclined posture of rinforcement bar 7 is set to the connection corner of T-type plate 3 Yu horizontal top 2, under oblique rinforcement bar 7
End is connected with vertical reinforcement net 6, upper end same level steel mesh 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 rinforcement bar 5, upper level
Rinforcement bar 5 and lower horizontal rinforcement bar 5 are respectively arranged 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 the ability of end shearing resistance and torsion, keeps away
A possibility that exempting from influence of the stress to end thick section 4, reducing the crack generated in the middle part of horizontal top 2.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, a possibility that reducing the crack of 1 end of T plate generation.The tilt angle control of oblique rinforcement bar 7
It is suitable for the tilt angle using 40 °, there are preferable stability between 30 ° to 50 °.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 tilt angle 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 increases accordingly.
Above-mentioned horizontal mesh reinforcement 8, vertical reinforcement net 6, and tiltedly between rinforcement bar 7, horizontal reinforcing muscle 5 phase is realized by steel wire lashing
Mutual connection status.
The advantages of the present embodiment are as follows: by preventing to the end-thickened ability for improving end shearing resistance and torsion of horizontal top 2
Only the ability in crack occurs for 1 end of T plate；The ability of end shearing resistance and torsion is further increased by reinforced steel, it is less
The influence of stress in casting process；Simple structure, easy to process, strong applicability.
