Hoop, length direction of the clip along the column, which is spaced to turn up the soil, is fastened on the periphery of the column.
According to a preferred embodiment, the column is along the direction concrete perfusion from fixing end to free end or fills out
Fill filler.
According to a preferred embodiment, one layer of continuous precursor felt is provided with the outer surface of the column.
According to a preferred embodiment, four corner configurations of the column are fillet part.
According to a preferred embodiment, the block includes being used for the base engaged with the free end of the column, with
And the extension for being arranged on the top surface of the base and being stretched out at an angle relative to the base.
According to a preferred embodiment, the extension includes connecting hole, and removing for the extension is disposed with the company
The regional structure for connecing hole is area of knockout.
According to a preferred embodiment, the clip includes two U-shaped fasteners, and each fastener includes basal part
Point, the leg that is stretched out with being respectively perpendicular from the both ends of the base part, and stretched out from the end horizontal of each leg
Flange, the flange is provided with perforate.
According to a preferred embodiment, two are additionally provided with the base part of the fastener and the outer surface of leg
Semicircular ribs parallel to each other.
Brief description of the drawings
Other details of the present utility model and advantage are illustrated below with reference to accompanying drawings.
Fig. 1 shows the front view according to columns assemblies of the present utility model；
Fig. 2 shows the stereogram according to columns assemblies of the present utility model；
Fig. 3 shows the structural representation of the clip in columns assemblies of the present utility model.
In this application, all accompanying drawings are schematical accompanying drawing, are merely to illustrate principle of the present utility model, and not
It is drawn to scale.
Embodiment
The utility model is introduced below by way of accompanying drawing.
Fig. 1 and Fig. 2 respectively illustrates the front view and stereogram according to columns assemblies 100 of the present utility model.As schemed
Show, include column 110 according to columns assemblies 100 of the present utility model, it is used for installed in the both sides of railway track.Column 110
Including two ends, the bottom shown in Fig. 1 and 2 is fixing end, for being inserted into inside ground and being fixed in ground, Fig. 1 and 2
Shown in top be free end.
Column 110 is configured to long and narrow open column shape body, and chamfering can be provided with its four corners.Set in column 110
Have intermediate rib (not shown), its extension of length along column 110, so as to by the hollow lumen of column 110 be divided into two it is parallel
Separate space.Be long and narrow open column shape body in view of column 110, intermediate rib can significantly increase the shearing strength of column 110 with it is curved
Bent modulus.
According to the utility model, column 110 is made of fiberglass reinforced plastics.Relative to steel or concrete material
Column, this column 110 has lightweight, high-strength, pollution-free, burn into is not cheap, production efficiency is high, the spy such as easy to maintain
Point.
According to one embodiment of the present utility model, can be irrigated in the inner compartment of column 110 along the length of column
Concrete.It is of course also possible to be advantageous to increase column bending rigidity using other and resist the filler of environmental corrosion, such as water
Mud, mortar etc..
Good intensity and bending resistance, shearing strength are possessed according to column 110 of the present utility model, can prevent from toppling.
According to a preferred embodiment, one layer of continuous glass fiber precursor felt is provided with column 110 and (is not shown
Go out).Glass fiber precursor felt can be covered in the whole surface of column 110.Precursor felt can increase the lateral pull of column simultaneously
Surface quality is improved, to resist the corrosion of external environment column 110.
As illustrated in fig. 1 and 2, block 120 is also included according to the columns assemblies 100 of first embodiment of the present utility model, its
Top in the free end of column 110, i.e. Fig. 1 and 2.Block can use sheet-shaped moulding material through SMC process stempressing systems
Into.Thus, block 120 can prevent foreign object, sleet, dust etc. from entering in the inner compartment of column 110, can extend column 110
Service life, while also cause column 110 it is more attractive in appearance.
As illustrated in fig. 1 and 2, clip 130 is also included according to columns assemblies 100 of the present utility model.From the figure, it can be seen that
Several length directions of clip 130 along column 110 are distributed at interval, and are fastened on the periphery of column 110.Clip
130 are used to link together on column 110 and fence (not shown).
By setting these clips 130, the rigidity and intensity of long and narrow column 110 can be strengthened, significantly improve column
110 stability and durability.
Preferably, all clips 130 are arranged in the top half of column.It is long and narrow thereby, it is possible to further strengthen
The rigidity and intensity of column 110, and ensure the stability of fence fixed by the column.
In a preferred embodiment, clip 130 is made using sheet-shaped moulding material through SMC process stempressings.Sheet mould
Moulding material has the characteristics that good corrosion resistance high-weatherability, mechanical property, weatherability.Therefore, made of this material
Clip 130 can be widely applicable for various rugged environment conditions, and good protective action is provided for column 110.
Fig. 3 is more clearly illustrated according to clip 130 of the present utility model.As illustrated, clip 130 includes two structures
Identical fastener 131.Fastener 131 is substantially U-shaped, including base part 132, is hung down respectively from the both ends of base part 132
The leg 133 directly stretched out, and the flange 134 stretched out from the end horizontal of each leg 133.Flange 134 is provided with perforate
135, fence (not shown) may pass through the perforate 135, and is connected by bolt, pad etc. with clip 130.Flange 134 constructs
Into flat plate.The flange 134 of two fasteners 131 is buckled togather, so as to form the cavity for accommodating column 110.
Thus, column 110 and fence can be linked together by clip 130.
According to a preferred embodiment, in fastener 131, the join domain of base part 132 and leg 133 and
The join domain of leg 133 and flange 134 is all formed as arc transition region.In this way, stress concentration is avoided, together
When preferably can also be engaged with column 110, realize the reasonability of external force transmission.
In addition, according to a preferred embodiment, in the base part 132 of fastener 131 and the outer surface of leg 133
It is additionally provided with two ribs 136 parallel to each other.The section of this two ribs 136 is semicircle, respectively along fastener 131
Upper and lower end extension, it is and preferably concordant with upper and lower end edge.By setting ribs 136, the bending resistance of clip 130 can be improved
Rigidity and the ability of resistance to deformation, while also increase stability.
It was found from foregoing description, circular arc or approximate circular arc are had according to the clip 130 of the utility model first embodiment
The exterior contour of shape.Thus, the ability of the resistance wind load of columns assemblies 100 is substantially increased, so as to ensure that itself
