Specific embodiment
The utility model is described further with reference to the accompanying drawings and examples as follows:
A kind of light-duty shed hole structure quickly built, as shown in Figure 1, Figure 2 and Figure 3, including column, crossbeam 3 and top plate 4；
The column is arranged in pairs, and every column includes the outer heel post 2 of the interior heel post 1 and the other side positioned at hangar tunnel side；And
Several interior heel posts 1 are along hangar tunnel longitudinal direction spaced set, and several outer heel posts 2 are also along hangar tunnel longitudinal direction spaced set；Every opposition
Column configures a crossbeam 3, and described 3 one end of crossbeam is installed on the top of interior heel post 1, and the other end is installed on corresponding outer heel post
2 top；The top plate 4 is spliced along hangar tunnel longitudinal direction by multi-disc top plate unit 41, is configured between adjacent two crossbeams 3 a piece of
Top plate unit 41, and the both ends of the top plate unit 41 are held on the top of corresponding crossbeam 3 respectively.
The light-duty shed hole structure that the one kind is quickly built is different from common skeleton hangar tunnel, is erected on by the way that crossbeam 3 is arranged
Pair interior heel post 1 and the top of outer heel post 2, top plate 4 is spliced along hangar tunnel is longitudinal by multi-disc top plate unit 41, and each top
Plate unit 41 is overlapped on two adjacent crossbeams 3, carries out vertical linkage without stringer between each column between each crossbeam 3, is indulged
It is big to the relatively conventional frame of span；It can optionally short time control only when installing crossbeam 3 and top plate 4 without disconnected road when construction
It is current；And prefabricated component can be used in the structural beams and top plate, to greatly shorten on-site construction time, reduce and hand over existing road
Logical interference and influence；Moreover the investment due to being not necessarily to stringer, therefore, without the working procedure that stringer is connect with crossbeam, to save
About working procedure, without disconnected road construction.
Wherein, interior heel post 1 can be reinforced concrete square column, can also all use anchor bar steel to inslope basement rock massif
Muscle concrete barricade is protected, and plays the role of support beam 3 for basement rock massif as interior heel post 1.The general position of outer heel post 2
In the slope cliff side far from side slope neighbour river neighbour's cliff, it typically is the concrete filled steel tubular columns being fixed on reinforced concrete pile foundation.
In order to guarantee reliability that crossbeam 3 is connect with column, as shown in figure 5, the cross section of the crossbeam 3 is T-shaped；It is described
The top of outer heel post 2 and interior heel post 1 is respectively provided with steel case and expands head 10, the steel case expand be reserved on head 10 opening upwards with
The T-slot mouth 11 that crossbeam 3 is adapted to；One end of the crossbeam 3 is installed in the T-slot mouth 11 of outer heel post 2, and the other end is installed on
In the T-slot mouth 11 of interior heel post 1.
When specific installation, column top and crossbeam 3 are affixed, and T shape is reserved in 10 factory of the Gang Xiangkuotou production that column top uses
Notch 11 makes convenient and can be carried out standardized production, guarantees that steel case expands the dimensional accuracy of head 10.3 in-situ precast of crossbeam, end
Both sides of head embedded bar, after lifting is in place, cast-in-place self-compacting concrete forms consolidation in the cabinet that steel case expands head 10.Certainly,
The top of outer heel post 2 and interior heel post 1 can not use steel case to expand the structure of head 10, can be directly in outer heel post 2 and interior
The T-slot mouth 11 of the top production opening upwards of heel post 1 being adapted to crossbeam 3, or its except head 10 is expanded using steel case
Its connector etc..
In order to further shorten the construction time, it is preferred that as shown in figure 3, the top plate unit 41 is by multi-disc prefabricated unit
Plate 411 is assembled along 3 extending direction of crossbeam.
Top plate unit 41 is made of multi-disc prefabricated unit plate 411, compared with full wafer top plate unit 41, prefabricated unit plate
411 transports, production and lifting etc. are easier, and difficulty of construction is low, is conducive to shorten the construction period.
Preferably, as shown in figure 3, forming the ribbet 412 of opening upwards between adjacent two pieces of prefabricated unit plates 411,
And ribbet 412 uses concrete backfill.
After connecting adjacent two pieces of prefabricated unit plates 411 by ribbet 412, each prefabricated unit plate 411 connects entirety,
The overall stiffness of top plate is enhanced, and spelling of the water of shed tunnel top between adjacent two pieces of prefabricated unit plates 411 is more avoided
Seam is lower to be seeped to traffic space.
When construction, it will usually which side pours concrete waterproof layer 5 on the top plate 4, and the concrete filled in ribbet 412 can be anti-with concrete
Water layer 5 is structure as a whole, to keep the concrete waterproof layer 5 of top closer in conjunction with top plate, keeps waterproof performance more preferable.
Prefabricated unit plate 411 can be solid construction, and T-type section or other section forms etc. can also be used, still, real
The prefabricated unit plate 411 of the heart is heavier, and installation is inconvenient with lifting；And T-type depth of section is much larger than board-like section.As shown in figure 3,
The prefabricated unit plate 411 is the cored slab structure of simple structure.
In order to meet waterproof requirement, it is preferred that as shown in figure 3, square one-piece casting has concrete waterproof layer 5 on the top plate 4.
In order to buffer impact of the top falling rocks to top plate 4, it is preferred that as shown in figure 3, being provided with above concrete waterproof layer 5
Buffer layer；The buffer layer includes foamed cushioning pads layer 6 and the waste tire layer 7 above foamed cushioning pads layer 6.
In order to increase the overall stability of hangar tunnel, it is preferred that as shown in Figure 2 and Figure 4, the interior heel post 1 is located at side slope
Place side；Barricade 8 has been poured between adjacent two interior heel posts 1.
The setting of barricade 8 increases longitudinal globality of hangar tunnel, so that the overall stability of hangar tunnel is improved, meanwhile, it is also right
Side slope plays protective action, and can prevent Falling Rocks, mudstone etc. from entering to be formed through the gap between adjacent two interior heel posts 1
The effect in space.
In order to increase longitudinal globality of hangar tunnel, it is preferred that as shown in figure 4, each interior heel post 1 is through anchor pole 9 and side slope
Basement rock is connected.
Interior heel post 1 is fixed on side slope basement rock by anchor pole 9, the lateral stiffness of hangar tunnel is increased, to improve canopy
The overall stability in hole.
In order to avoid top plate unit 41 is under the Vibration Conditions such as earthquake, slid along 3 extending direction of crossbeam, it is preferred that described
Block 31 is respectively arranged at the top of 3 both ends of crossbeam, the top plate unit 41 is located between the block 31 at both ends, and through block 31
Top plate unit 41 is constituted along 3 extending direction of crossbeam and is limited.
In order to meet draining and play the role of it is certain avoid rock-drop accumulations in shed tunnel top, crossbeam 3 is usually along inside
To lateral direction in tilting down setting, therefore, for installing the mounting surface of top plate for inclined surface, in order to guarantee to push up above crossbeam 3
The stability of plate installation, therefore, the bearing pad stone 32 of wedge shape is installed on the mounting surface above crossbeam 3, passes through bearing pad stone 32
Inclined mounting surface is converted to horizontal mounting surface by horizontal faulting of slab ends, to improve the stability of mounting of roof plate.
