Description
Technical field
The utility model is related to a kind of anticollision device, collision-prevention devices, and in particular to a kind of detachable concrete filled steel tube bumping post.
Background technology
Car bombing is subject to for regions such as important building, large-scale public place and dense populations to threaten,
Foreign countries design a variety of fixed anticollision systems in this area periphery：Bumping post, Anti-collision railing etc., it is larger with vehicle flowrate in flow of the people
Place fixed anticollision system be set easily lead to have inconvenient traffic and fix the basis of anticollision system after shock and also want one
With removing, inconvenience is caused to daily life；Domestic current anticollision system for the purpose of warning function, crashworthiness compared with
Difference cannot effectively stop that car bombing and truck collide, and automatic-lifting type bumping post is to dilly (family-sized car, skin
Card etc.) there is good blocking effect, but it is poor to truck blocking effect (comparison DOS specifications) more than twin shaft, because its own
Height is smaller, and truck remains to slide relatively long distance after crossing bumping post, remains to threaten to the safety of building and crowd.
If the detachable concrete filled steel tube bumping post detached with shaft using basis in Practical Project is (before being hit
It is detachable afterwards), it can not only improve space availability ratio and increase the recycling number on basis, but also can effectively reduce input
Cost more can effectively stop the attack of truck bomb.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and it is anti-to provide a kind of detachable concrete filled steel tube
Hit column.
The technical solution adopted in the utility model is：A kind of detachable concrete filled steel tube bumping post, including top shaft
Basis is expanded in structure and lower part；
The upper post body structure includes shaft, rotating handles, annular cover plate, peg, sleeve and hole slot retaining wall, the column
Rotating handles are installed on the side wall of body, in the lower end insertion sleeve of shaft, annular cover plate are equipped with above sleeve, cartridges sides are set
There are L-shaped rectangular channel, L-shaped rectangular channel to be closed by hole slot retaining wall, the sleeve is welded in L-shaped rectangular channel corresponding position suitable for reading
Peg；
The lower part expands basis and is welded by channel steel, and lower part expands basis and existed by connecting plate and the sleeve weld
Together；
The lower part is expanded and is filled with normal concrete in basis and shaft, is furnished with reinforcing bar in normal concrete.
Preferably, the shaft is made of seamless steel pipe, strength grade Q345B, shaft using annular cover plate as line of demarcation,
The above length of steel pipe of annular cover plate is 1200mm, and the following length of annular cover plate is 440mm, and shaft outer diameter is not less than 203mm, wall thickness
Between 10mm~20mm.
Preferably, the rotating handles are made of the reinforcing bar of two root long 150mm and a diameter of 20mm, it is placed in annular cover plate
At the 200mm of top, fillet weld weld all around is used with shaft, two rotating handles are point-blank.
Preferably, the annular cover plate cuts into annulus, strength grade Q235B, annular by the steel plate that thickness is 10mm
Cover board is connect with shaft using fillet weld, 2 grades of weld seam grade；The effect of annular cover plate：It bears the dead weight of shaft and prevents dust
Enter in sleeve with moisture etc..
Preferably, the peg is made of the bolt of two specification M18, in advance in the trepanning of shaft designated position, trepanning
Diameter is slightly larger than the diameter of bolt, ensures that bolt can be by stretching to outside, extension inside shaft across hole, bolt
20mm cuts additional length, and peg uses fillet weld weld all around with shaft, welds 2 grades of grade.
Preferably, the sleeve is made of seamless steel pipe, strength grade Q235B, sleeve diameter is bigger than shaft outer diameter
8mm, it is ensured that easy for installation, shaft cuts L-type rectangular channel in the both sides in vertical Vehicular impact direction, is closed by hole slot retaining wall,
Entire top shaft can slide in the L-type hole slot of formation.The hole slot retaining wall is after sleeve fluting, to prevent concreting
When mortar penetrate into sleeve, therefore cut with sheet metal and weld it is integral sleeve slotted section is closed just, then hole slot is protected
For wall with sleeve by fillet weld seam, weld seam is uninterrupted and seamless.
Preferably, the connecting plate is made of the steel plate that four pieces of thickness are 10mm, strength grade Q235B, for connecting
Sleeve expands basis with lower part, is all made of fillet weld connection, 2 grades of weld seam grade.
It is made of 4 channel steels preferably, basis is expanded in the lower part, strength grade Q235B, specification 20a, channel steel and slot
It is connected using fillet weld between steel, 2 grades of weld seam grade.
The utility model around the important building entrance or crowd massing at perimeter security distance arrangement it is detachable
Formula bumping post, between adjacent two bumping post away from should be less than body width.
Detachable bumping post general description of construction：Excavation pit (the bumping post lower junction first except building certain distance
Structure is placed in foundation pit, and sleeve top surface is flushed with ground), detachable bumping post substructure is sunk into foundation pit, arranges steel
Muscle is simultaneously bound, and pours foundation pit inner concrete and top shaft steel pipe inner concrete respectively；Meeting will be upper after the concrete curing period
Portion's shaft is inserted into component 5 and rotates clockwise.
Note：Substructure is embedded in basis, and when not installing superstructure, sleeve diameter influences normal traffic compared with conference,
Certain thickness steel plate need to be added to ensure vehicular traffic and the safety of pedestrian in upper cartridge.
For detachable bumping post due to being had the gap between bottom shaft and sleeve, the assembling between shaft and sleeve is to pass through
The peg being welded on shaft is rotated and is stuck in the L-type hole slot of sleeve.After Vehicular impact bumping post, shaft shakes in sleeve
Dynamic to consume portion of energy therefore shaft overall deformation is smaller, truck cannot cross bumping post；Due to peg arranged direction and shock
Direction vertically thus knockout process influences it smaller, remain to dismantle after shock.
Advantageous effect：The utility model important building (school, hospital etc.) and dense population concentrated area safety away from
Detachable bumping post is installed from except, can effectively by the vehicle for carrying bomb or other dangerous material be blocked in safe distance it
Outside, it explodes in time, with the increase of distance, explosion wave and bomb fragments are bright to the injury of important building and crowd
It is aobvious to weaken, it reduces and reduces the loss caused by the attack of terrorism and casualties.
Currently, bumping post is largely build-in type, need together to remove basis after shock, cost is higher, and bumping post can not
It recycles and the process-cycle is long；For automatic-lifting type stainless steel bumping post by shaft height limitation, to dilly (family
With car, pick up etc.) there is good blocking effect, but it is poor to truck blocking effect more than twin shaft, truck crosses bumping post
After remain to slide relatively long distance, the safety of building and crowd is remained to threaten.
Using the utility model will can effectively hit vehicle be blocked in important building and dense population safe distance it
Outside, while input cost can be effectively reduced, foundation recycles, and improves space utilization rate.
