Concrete pole signboard fixing device
Technical field
The present invention relates to Sign Board field engineering field, specifically is a kind of concrete pole signboard fixing device, is applicable to that mainly the Sign Board on the power circuit concrete bar is installed.
Background technology
For maintenance and security needs, on power circuit concrete bar, generally all Sign Board to be installed, at present the most methods that adopt the iron wire colligation of the Sign Board on the concrete bar.Because power circuit concrete bar is in the outdoor or open-air environment, the time has been grown iron wire, and rust is disconnected easily, causes Sign Board to come off automatically; Bring potential safety hazard to the maintainer; Reporting for line inspection and defective impacts; Often to before maintenance, check circuit in the scene, increase workload.Sign Board on the concrete bar is lost easily at present, and does not have unified installation site and mode, and it is mixed and disorderly especially to make Sign Board install.
Summary of the invention
To the shortcoming of above-mentioned prior art, the present invention provides a kind of concrete pole signboard fixing device, utilizes this fixture constant mark board installation method easy, and makes the Sign Board on the concrete bar install neat.
The present invention realizes with following technical scheme: a kind of concrete pole signboard fixing device comprises fixing device I of being made up of web joint, bolt and the fixing device I I that is made up of U type anchor ear and angle bar; of angle bar help have match with U type anchor ear and the hole, the hole that the openend of U type anchor ear passes on the angle bar is fastening with nut; Web joint is that an end is bent with the hook solid that can be stuck on the angle bar, and the other end has the band iron of slotted hole; One end of bolt is bent with the hook solid that can be stuck on the angle bar, and the slotted hole that the screw thread end passes on the web joint is fastening with nut.
The invention has the beneficial effects as follows: make simply, be difficult for disappearance, be not prone to phenomenons such as artificial destruction; What Sign Board was neat is installed on the concrete bar, has improved the job security in line maintenance or the construction transformation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the fixing device I structural drawing;
Fig. 2 is a fixing device I I structural drawing.
Among the figure: 1, web joint; 11, slotted hole; 2, bolt; 3, U type anchor ear; 4, angle bar; 41, hole.
Embodiment
As depicted in figs. 1 and 2, concrete pole signboard fixing device, fixing device I of being made up of web joint 1, bolt 2 and the fixing device I I that is made up of U type anchor ear 3 and angle bar 4 form.Help of angle bar 4 and to have the hole 41 of matching with U type anchor ear 3, the hole 41 usefulness nuts that the openend of U type anchor ear 3 passes on the angle bar 4 are fastening.Web joint 1 is a band iron, and the one of which end is bent with the hook solid that can be stuck on the angle bar 4, and the other end has slotted hole 11.One end of bolt 2 is bent with the hook solid that can be stuck on the angle bar 4, and the slotted hole 11 usefulness nuts that the screw thread end passes on the web joint 1 are fastening.In the present embodiment, web joint 1 is the band iron of long 100mm, wide 50mm, thick 5mm; Crotch on web joint 1 one ends is a 45, helps for one that is used for firmly colluding at angle bar 4.Slotted hole 11 is apart from the width of the group of the distance h≤angle bar 4 of web joint 1 crooked position; Slotted hole 11 long 50mm, wide 8mm had not only satisfied multiple angle bar size but also had satisfied 6mm diameter bolt penetrating.Because the Sign Board mounting hole is generally normal diameter 8mm, therefore adopting bolt 2 diameters is 6mm, the bolt of long 100mm; Bolt 2 one end crotches are 45, are used for firmly colluding at another of angle bar 4 helping.Can change the size of web joint 1 and bolt 2 in addition according to the size of angle bar 4, with the fastness that guarantees that Sign Board is installed.
Installation process is: first mounting fixing parts II: U type anchor ear 3 is stuck on the concrete bar, and the hole 41 usefulness nuts that its openend passes on the angle bar 4 are fastening, and fixing device I I just is fixed on the concrete bar.Mounting fixing parts I again: the crotch end hook of web joint 1 is lived a group of angle bar 4, and the crotch end hook of bolt 2 is lived another group of angle bar 4; Bolt 2 screw thread ends pass the slotted hole 11 on the web joint 1, Sign Board are through on the bolt 2 again, get final product with nut is fastening.
