Specific embodiment
In order to make the purpose of this utility model, technical solution and advantage clearer, below in conjunction with attached drawing to this practicality
It is new to be described in further detail, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than
Whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work
Under the premise of all other embodiment for being obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, Fig. 1 shows the structure diagram for the fence unit 10 that the utility model embodiment provides.At this
In the fence unit 10 that embodiment provides, including three parts, column 11, first crossbeam 13 and second cross beam 12；Wherein, column
11 number can be for one or multiple, and as shown in fig. 1, the column 11 of fence unit 10 provided in this embodiment is
One, the column 11 is for fixing on the ground, with support beam.In specific set, the basis of the column 11 is generally beaten
Enter formula basis and concrete foundation, so that column 11 can be stably fixed on ground.
The number of crossbeam provided in this embodiment is two, respectively first crossbeam 13 and second cross beam 12, specifically such as
Shown in Fig. 1, first crossbeam 13 and second cross beam 12 are arranged in parallel along short transverse, and first crossbeam 13 is located at second cross beam 12
Top.In specific set, the width of the second cross beam 12 is more than the width of first crossbeam 13, so that 12 energy of second cross beam
The forced area of enough biggers.So that automobile, when only bumping against second cross beam 12, second cross beam 12 is capable of providing larger delay
Impulse force, to provide protection.Such as three compartment of the prior art automobile, due to the limitation of its height, in collision, it is most likely that only
Second cross beam 12 is bumped against, at this point, first crossbeam 13 can not provide cushion effect, the cushion effect that second cross beam 12 can only be leaned on to provide, and
In the fence unit 10 provided in the embodiment of the present application, the width of second cross beam 12 do it is wider, in specific set, second
The width of crossbeam 12 is 1.2~1.5 times of 13 width of first crossbeam, such as 1.2 times, 1.25 times, 1.3 times, 1.35 times, 1.4 times,
1.45 times, 1.5 times.When width such as first crossbeam 13 is 120mm, the width of second cross beam 12 is 150mm.So that second
The width of the cross section of crossbeam 12 is more than the width of the cross section of first crossbeam 13, i.e., when being contacted with automobile, second cross beam 12
The contact area with automobile is increased, and then improves the protection to automobile.
In specific set, in order to improve the intensity of fence unit 10 and protective capability, column provided in this embodiment
11st, first crossbeam 13, second cross beam 12 use square steel tube as support force.Specifically as shown in Figure 1, column 11 uses square steel
Pipe, and in specific set, which is enclosed with towards the one side of first crossbeam 13 and the two sides adjacent with the face
Protective layer 14.That is three side wraps of column 11 protective layer 14, in addition, first crossbeam 13 and second cross beam 12 also wrap up
Protective layer 14, and first crossbeam 13 and second cross beam 12 be in packing protective layer 14, except first crossbeam 13 and second cross beam 12
Towards outside the non-packing protective layer 14 of one side of column 11, protective layer 14 has been wrapped up in remaining three face.The protective layer 14 can be with
It is formed by different material preparations, it is only necessary to be capable of providing buffering in collision.Such as in a specific embodiment,
The protective layer 14 is bamboo fibre layer.I.e. the protective layer 14 is suppressed by bamboo fibre, has certain strength and stiffness, Bu Huifei
It splashes.Certainly other materials, such as the material that plastics, rubber are common can also be used.
With continued reference to Fig. 1, in the present embodiment, the top of each column 11 is provided with capping 15.The capping 15 is used to seal
The open top of stifled square steel tube so as to which sundries be avoided to enter in square steel tube, and causes column 11 to form the pipe of a closing
Shape improves support strength.Capping can be made into other patterns, enhance landscape effect.
In specific connection, first crossbeam 13 and second cross beam 12 are fixedly connected respectively by bolt with each column 11.
As shown in fig. 1, every crossbeam is fixedly connected when being connected with column 11 by bolt with column 11, bolt through crossbeam with
And it is screwed into column 11 and is fixedly connected with column 11 after the protective layer 14 on crossbeam.Preferably, the bolt can both be adopted
With nut bolt, the bolt of nut, specific occupation mode and bolt of the prior art can also be could be used without
Occupation mode is identical, and in this not go into detail.
Together with reference to 2~Fig. 5 of figure, the present embodiment additionally provides a kind of guardrail, wherein, Fig. 2 shows that the decomposition of guardrail is shown
It is intended to；Fig. 3~Fig. 5 shows the structure chart of the different angle of guardrail.First refering to fig. 2, Fig. 2 is shown using two guardrail lists
The decomposition diagram of the guardrail of 10 composition of member.In guardrail in the present embodiment, including multiple above-mentioned fence units 10, and
Multiple 10 single-row arrangement of fence unit, and be fixedly connected between adjacent two fence units 10.As shown in Fig. 2, two guardrails
Single-row arrangement, and be fixedly connected between guardrail by connecting plate 20.In specific set, the in adjacent fence unit 10
It is fixedly connected between one crossbeam 13 by connecting plate 20, passes through connection between the second cross beam 12 between adjacent fence unit 10
Plate 20 is fixedly connected.I.e. in specific installation, first crossbeam 13 is connected with first crossbeam 13 forms an entirety, second cross beam 12
It is connected with second cross beam 12 and forms an entirety.And when first crossbeam 13 and second cross beam 12 are using square steel tube, connecting plate
20 are inserted respectively into square steel tube, and the both ends of crossbeam are fixedly connected respectively with two square steel tubes.As shown in Figures 2 and 3, exist
During specific connection, adjacent two square steel tube docking, and connecting plate 20 is plugged between two square steel tubes, is specifically being connected
When, one end of connecting plate 20 is fixedly connected by least two bolts with square steel tube, so as to ensure between crossbeam and square steel tube
Bonding strength when fixed when avoiding the guardrail from shielding, is disconnected from the junction of crossbeam.Improve the protection energy of guardrail
Power.And guardrail provided in this embodiment due to use above-mentioned fence unit 10, by using the width of second cross beam 12
Degree, so as to improve the cushion effect that second cross beam 12 is provided in deformation, is improved to height more than the width of first crossbeam 13
Relatively low automobile protection.
Obviously, those skilled in the art can carry out the utility model various modification and variations without departing from this practicality
New spirit and scope.If in this way, these modifications and variations of the utility model belong to the utility model claims and
Within the scope of its equivalent technologies, then the utility model is also intended to comprising including these modification and variations.
