Abstract
The utility model relates to a lock-connected road barrier, which belongs to the technology field of road safety devices. The utility model consists of an upright post and a horizontal barrier positioned between adjacent upright posts. Both ends of the horizontal barrier are respectively locked and connected with two adjacent upright posts. The adoption of the lock-connected road barrier can facilitate to separate the barrier component, which requires maintaining and replacing, from the whole barrier rapidly, thereby facilitating the maintenance and replacement of the barrier, improving the maintenance efficiency effectively and saving maintenance cost.
Description
Technical field
The utility model relates to a kind of road guard, and especially a kind of improvement that is used for the travels down vehicle is carried out the guard bar structure of anticollision belongs to road safety device technique field.
Background technology
At present generally all be provided with guardrail on the centre and the both sides of different kinds of roads and super expressway, guardrail mainly forms by the blocking assembly that orthogonal column and horizontal bar constituted is end to end successively, and the column of blocking and horizontal bar assembly generally all are to adopt concrete to add the structure of steel pipe or the structure that the employing steel pipe adds steel plate.
The patent No. that the applicant also announces in first to file is that the Chinese patent application of ZL200620077445.0 discloses a kind of buffering road guard; This guardrail also is to be made of orthogonal column and horizontal bar unit, but because horizontal bar is made of flexible steel cable inner core overcoat plastic pipe, therefore can play good cushioning effect to the collision of driving vehicle out of control, thereby improves traffic safety.
But the applicant finds, the described guardrail of patent that existing different kinds of roads guardrail comprises above-mentioned applicant, it is very inconvenient to carry out maintain and replace after being collided by driving vehicle out of control, this be because, between each unit component parts of guardrail all is fixedly connected, when changing wherein some or several component parts, just have to destroy the unit component parts or plurality of units is changed together.Such as, in the disclosed patent of above-mentioned applicant, when horizontal bar need be changed damaged overcoat plastic pipe, just be difficult under the situation of motionless other assembly, change easily; And when needing to change the flexible steel cable inner core of some unit horizontal bar, then have to the flexible steel cable inner core that plurality of units links together is all changed.For another example, for the steel pipe horizontal bar that is fixed in the concrete column, no matter only be that column damages or horizontal bar damages, all have to all change.To sum up, above-mentioned different kinds of roads guardrail is the maintain and replace inconvenience not only, and maintenance cost is also high.
The utility model content
Technical problem of the present utility model is: at the problem of above existing road guard bar device existence, a kind of interlocking formula road guard is proposed, this guardrail passes through the openable lock-connection structure of design between its assembly, thereby makes things convenient for the guardrail maintain and replace and reduce maintenance cost.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of interlocking formula road guard, comprise column and the horizontal bar between adjacent upright posts, the improvement of scheme is: the two ends of described horizontal bar respectively with the adjacent upright posts interlocking.
Like this, when the column of guardrail unit and horizontal bar because of damaged when needing maintain and replace, can from horizontal bar and column interlocking horizontal bar and column be separated easily, then this unit column and horizontal bar after separating be carried out maintain and replace, thereby improve maintenance efficiency greatly and save maintenance cost.In addition, the lock-connection structure of horizontal bar should guarantee the guardrail use of normal safety at ordinary times.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the amplification stereogram of the lock body of lock-connecting piece among Fig. 1.
Fig. 3 is the amplification stereogram of the tapered end of lock-connecting piece among Fig. 1.
The specific embodiment
Embodiment
The interlocking formula road guard of present embodiment comprises column 1 and the horizontal bar between two adjacent upright 12 as shown in Figure 1, and the both sides that connect with horizontal bar 2 at column 1 are provided with lock body 3, and the end at the two ends of horizontal bar 2 is provided with tapered end 4; When tapered end 4 was in the position of inserting in the lock body 3, interlocking was together each other for horizontal bar 2 and column 1.Lock body 3 is fixedly connected with column 1, and connecting mode can be welding or Bolt Connection.
Column 1 and horizontal bar 2 and between draw bail can be the patent document of ZL200620077445.0 referring to the disclosed patent No. of above-mentioned applicant.
Understand easily, the interlocking formula road guard of present embodiment is compared with existing different kinds of roads guardrail, owing to horizontal bar is designed to two sections of interlocking each other, thereby when needing repairing the replacing guardrail, can be rapidly easily with the guardrail formant assembly (column 1 and horizontal bar 2) of required maintain and replace, from whole guardrail, separate, thereby make things convenient for the maintain and replace of guardrail.
The interlocking formula road guard that experiment showed, present embodiment after applicant's trial-production can effectively improve maintenance efficiency really and save maintenance cost.
In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (4)
1. an interlocking formula road guard comprises column and the horizontal bar between adjacent upright posts, it is characterized in that: the two ends of described horizontal bar respectively with the adjacent upright posts interlocking.
2. according to the described interlocking formula of claim 1 road guard, it is characterized in that: the both sides of described column are provided with lock body, and the two ends of described horizontal bar are provided with tapered end; When described tapered end was in the position of inserting in the lock body, interlocking was together each other for described horizontal bar and column.
3. according to the described interlocking formula of claim 2 road guard, it is characterized in that: described lock body and column are fixedly connected.
