Gangboard described in long insertion.
Preferably, the top of the ladder beam arranges a groove, and the plate face reinforcing bar is extended to along the gangboard length direction
Level is bent to behind its top, is then folded into the groove vertically downward；The reinforcement is along the gangboard length side
To extending to behind top the level that is bent to；One first anchor bar is also set up in the gangboard, and first anchor bar is from institute
The lower section for stating reinforcement extends upwardly to the plate face reinforcing bar and the reinforcement along the direction of the vertically gangboard length
Between, then its top is extended to along the gangboard length direction, then bending is to level.
Preferably, the first anchor bar horizontal segment is located at the lower section of the reinforcement horizontal segment.
Preferably, the horizontal-extending length of the horizontal segment of first anchor bar is more than the horizontal segment of the reinforcement
Development length.
Preferably, also include the landing slab of a ledge structure, the bottom of the gangboard is shelved on the landing slab and supports
Lean against on the step of the landing slab.
Preferably, after the plate face reinforcing bar and reinforcement all extend downward the gangboard bottom, bending is to level, institute
State in gangboard and one second anchor bar is also set up, second anchor bar is from the reinforcement along the gangboard length side
To extending to behind its underpart the level that is bent to；The horizontal segment of second anchor bar is located at the plate face reinforcing bar lower horizontal
Top.
The stair of the employing side-rolling ladder beam of the present invention can adjust the position of lower end cantilevered plate, thickness of slab, length, many to adapt to
The stair form of type, stair arrangement are more flexible：Bench for different spans, it is only necessary to adjust bridging piece thickness and
Choose length, by calculating, Reasonable Reinforcement, can just meet safety and the functional requirement of the bench of different spans；Strong for difference
The stair of degree, it is only necessary to check the Relative sliding that shake is gone downstairs between bench greatly, reserve the big Relative sliding beam for shaking bench of going downstairs, just
The Seismic Design Requirements of stair can be met.Side-rolling ladder beam of the present invention is arranged by rational structure, in the reliable delivery for ensureing power
Under so that simple structure, easy construction, duration and cost is saved, with significant economic benefit.And can be applicable to various across
Degree, under various antidetonation earthquake intensitys, the staircase design of various difference arrangement forms.
Description of the drawings
Fig. 1 is structural representation of the present invention using the stair first embodiment of side-rolling ladder beam；
Fig. 2 is structural representation of the present invention using the stair second embodiment of side-rolling ladder beam；
Fig. 3 is structural representation of the present invention using the stair 3rd embodiment of side-rolling ladder beam.
Specific embodiment
Specific embodiment to the present invention is described in further detail below.
As shown in Figure 1 to Figure 3, a kind of stair using side-rolling ladder beam of the present invention include a terraced beam 10 and are movably arranged on
Gangboard 12 on terraced beam 10.It is provided with gangboard 12 and marks time 14, gangboard 12 is poured for armored concrete and formed.Along which in gangboard 12
Length direction has poured plate face reinforcing bar 16 and reinforcement 18, plate face reinforcing bar 16 and the equal total length insertion gangboard 12 of reinforcement 18.
Take this structure, gangboard 12 with globality, and can relatively terraced beam 10 slide, so as to reach the function of antidetonation.
As shown in figure 1, the top of terraced beam 10 arranges a groove 20, the top of gangboard 12 is stretched in groove 20, to realize limit
Position.For this structure, reinforcement scheme is：Plate face reinforcing bar 16 is extended to behind its top along 12 length direction of gangboard and is bent to level,
Then groove 20 is folded into vertically downward；Reinforcement 18 extends to behind top, along 12 length direction of gangboard, the level that is bent to；
One first anchor bar 22 is also set up in gangboard 12, and the first anchor bar 22 is grown from the lower section of reinforcement 18 along vertical gangboard 12
The direction of degree is extended upwardly between plate face reinforcing bar 16 and reinforcement 18, then extends to its top along 12 length direction of gangboard
Portion, then bending is to level.Wherein, 22 horizontal segment of the first anchor bar is located at the lower section of 18 horizontal segment of reinforcement.First anchor
Gu the horizontal-extending length of the horizontal segment of reinforcing bar 22 is more than the development length of the horizontal segment of reinforcement 18.By the first anchor bar
The horizontal segment of 22 horizontal segment and reinforcement 18 collectively forms the top horizontal section of gangboard 12.
As shown in Fig. 2 the landing slab 24 of a ledge structure can also be arranged as required to, the bottom of gangboard 12 is shelved on flat
On platen 24 and it is resisted against on the step of landing slab 24, spacing to realize.Its reinforcement scheme：Plate face reinforcing bar 16 and reinforcement 18
After all extending downward 12 bottom of gangboard, bending also sets up one second anchor bar 26, the second anchoring steel to level in gangboard 12
Muscle 26 extends to behind its underpart, along 12 length direction of gangboard, the level that is bent to from reinforcement 18；The water of the second anchor bar 26
Flat section is located at the top of 16 lower horizontal of plate face reinforcing bar.
As shown in figure 3, the bottom at first embodiment top and second embodiment is combined by which, composition about one is equal
Spacing structure.
Above example is only a kind of present invention embodiment therein, and its description is more concrete and detailed, but can not
Therefore the restriction being interpreted as to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art,
Without departing from the inventive concept of the premise, some deformation and improvement can also be made, these belong to the protection model of the present invention
Enclose.Therefore, the protection domain of patent of the present invention should be defined by claims.
