Plane in extend, and the Part II 123 of base 121 is connected with extension 125.Thus, the rigidity and entirety of block 120
Stability is improved.
As shown in Figure 1A and 1B, clip 130 is also included according to the columns assemblies 100 of first embodiment 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 it is fastened on column
110 periphery.Clip 130 is used to link together on column 110 and fence (not shown).
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.
The SMC techniques and its advantage of above-mentioned production block are equally applicable to manufacture clip, therefore repeat no more here.
Fig. 4 more clearly illustrates the clip 130 according to first embodiment of the present utility model.As illustrated, clip 130
Including two structure identical fasteners 131.Fastener 131 is substantially U-shaped, including base part 132, from base part 132
The leg 133 that stretches out with being respectively perpendicular of both ends, and the flange 134 stretched out from the end horizontal of each leg 133.Flange
134 are provided with perforate 135, and fence (not shown) may pass through the perforate 135, and by bolt, pad etc. and with the phase of clip 130
Even.Flange 134 is configured to flat plate.The flange 134 of two fasteners 131 is buckled togather, and is used to accommodate so as to form
The cavity of 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

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, according to the column 110 of the columns assemblies 100 of the utility model first embodiment, block 120
Circular arc or generally radiused exterior contour are respectively provided with clip 130.Thus, the resistance of columns assemblies 100 is substantially increased
The ability of wind load, so as to ensure that the stability of itself.
Fig. 5 shows the column 210 in the columns assemblies according to the utility model second embodiment, and Fig. 6 shows that this is vertical
The cross-sectional end view of post 210.According to the column 210 of the utility model second embodiment and according to the utility model first embodiment
The difference of column 110 be, be equipped with outwardly fillet part 219 in four corner portions of column 210.By setting
Put fillet part 219 so that the exterior contour of column 210 tends to arc-shaped.Therefore, the resistance wind load of columns assemblies
Ability has obtained further raising, so as to ensure that the stability of itself.
Fig. 7 shows the block 220 in the columns assemblies according to the utility model second embodiment.It is vertical corresponding to being arranged on
The fillet part 219 of four corner portions of post 210, is provided with elbows 229 on the base of block 220.Thus, the energy of block 220
It is enough to be installed in a manner of being tightly engaged into column 210.The columns assemblies so formed have the robustness further improved.
According to the clip of the columns assemblies of the utility model second embodiment and according to the utility model first embodiment
The clip of columns assemblies is identical, is not repeated to describe herein.
Each part in columns assemblies of the present utility model, i.e. column, clip, block can be repeatedly utilized so that, change
Fast and easy.Not only light weight, intensity are high for they, and have the advantages of fire prevention.Columns assemblies itself are elegant in appearance, it is not necessary to
External decoration is carried out, and construction costs is also greatly reduced.
It following is a brief introduction of using the method that roll guard is installed according to columns assemblies of the present utility model.
First, the construction of upright post basic is carried out.The construction method of upright post basic mainly has three kinds.The first is using prefabricated
Basis, wherein, prefabricated upright post basic is placed after being excavated in column installation place, then prefabricated column is placed, afterwards with mixed
Solidifying soil or cement carry out closure reinforcing.It is for second to place column after being excavated in column installation place, while is fixed temporarily, so
After-pouring concrete simultaneously makes concrete reach design strength.The third is to place column after being excavated in column installation place, is entered simultaneously
Row is interim fixed, then pours high polymer material and high polymer material is reached design strength.
Then, then roll guard is installed.Here, some clips are first fastened on to the appropriate position of column, then will be anti-
Barrier shielding passes through the perforate of clip, and roll guard is fixed on column with bolt and pad (if necessary).
Finally, block is installed in the upper end of column.If necessary, another roll guard is passed through into the connecting hole in block.
The above method can be segmented, the operation simultaneously of subregion, Multi-working-surface.The strength and stiffness at column initial stage are higher, installation
After can carry out the installation of fence.If using the method for cast-in-place method concrete perfusion, concreting can the later stage one
Secondary or perfusion by several times.Block installed in concrete reach design strength after carry out, but can also be segmented, district operation.Apply
Man-hour is light, quick, installation cost is low, so as to accelerate construction speed.Prefabricated column overcomes the group of site operation tissue
Knit complicated, progress slowly, the shortcomings that big is influenceed by topoclimate, while have and do not limited by soil property, labor intensity is low, operation is simple
Folk prescription just, efficiency high the advantages of.
Finally it should be noted that the foregoing is only preferred embodiment of the present utility model, do not form to this
Any restrictions of utility model.Although the utility model is described in detail with reference to foregoing embodiments, for
For those skilled in the art, the technical scheme described in previous embodiment can still be modified, or to wherein
Some technical characteristics carry out equivalent substitution.All any modifications within the spirit and principles of the utility model, made, equally replace
Change, improve, should be included within the scope of protection of the utility model.
