Description

The mark slab of extrusion modling

The utility model relates to billboard and traffic sign base plate.

In the past, nearly all billboard and traffic sign boards all are to be made of framework and the panel that is fixed on the framework.Because its installation is time-consuming, the plate surface evenness is relatively poor, and fastness is undesirable, so the our factory has developed the spliced mark slab of extrudate and obtained patent in 1997.The spliced mark slab of extrudate of our factory's exploitation, though be enhanced at aspects such as fastness, plate face planarizations, and installation also makes things convenient for manyly than the frame type mark slab.But, enforcement along with standard GB 5768-1999 " road signs and graticule ", visibility to road sign is had higher requirement: the character of fingerpost expressing information, according to the road speed difference, regulation Chinese Character height is from 25cm to 70cm, thus the corresponding increase of mark plate face size that requires (the maximum 30m that reaches ²), and there is following deficiency in the our factory in the spliced mark slab of patent section bar of exploitation in 97 years: 1. the plate face is narrower, and concatenation unit is too much, makes the integral slab surface evenness not high; 2. adopt Bolt Connection between the splicing section bar unit, not only the slit occurs easily and influence the whole structure of mark plate, and cause trouble to field operation; 3. plate face connecting mode is single, is difficult to satisfy the needs of multiple different profile and large scale mark plate.

The purpose of this utility model is, improve the structure and the connecting method of the composing base of the existing spliced mark slab of section bar, form the substrate block number of mark plate and it is connected into whole connector with minimizing, improve mark plate integral smoothness and presentation quality, and on the basis that guarantees the mark plate fastness, reduce the splicing and the installation workload of mark plate.

For achieving the above object, the utility model has adopted following design scheme:

The spliced mark slab of section bar of the present utility model constitutes (referring to Fig. 1～3) by the substrate that intercepts from extrudate with the connector of its connection, it is characterized in that: described section bar has a width greater than 30 centimetres, length is less than 15 meters, the rectangle plane plate that thickness is 2.5～4.0 millimeters, these both sides of the edge, surface plate back side are provided with contour in the same way and perpendicular to the left and right sides sidewall of this surface plate, its right side wall appearance is provided with the edge and is connection draw-in groove fin and that become mouthful narrow inner width and location thrust draw-in groove, its left side wall with connect draw-in groove and the corresponding position of thrust draw-in groove, location on outwards be provided with respectively and can be mutually join card rib and the location pushing-stopping wedged edge that the end that engages is convexly curved with the former, also be provided with the reinforcing rib that 2-3 bar and surface plate combine as a whole at the back side of section bar surface plate, this reinforcing rib upper end is provided with the Bolt Connection groove of mouthful narrow inner width; Described connector is the fixedly card that the spring steel cross section of making becomes the Jiong type, and it rides end or the middle part that is stuck in aforementioned section bar substrate left and right sides wall, to prevent the thrust draw-in groove and the disengaging of the pushing-stopping wedged edge on another substrate on the substrate.

According to such scheme, issuable relative slippage between two substrates that join for reduction, can all widen 4～5mm to the width of the connection draw-in groove of section bar and location thrust groove, and open several diameters at the upper top of location thrust bottom land and be not less than and connect the through hole that pushes up the gap of locator card rib on the draw-in groove, to be inserted in this gap with the thrust pin of the tip through this hole, make the base plan relative position stable more, accurate, and easier assembling.

According to the previous designs scheme, aforementioned connection draw-in groove and thrust groove can also be united two into one, offer the right-angled trapezium groove of inner wide and outer narrow at right side wall, and on bottom land, have several equally distributed and tangent through holes of last end face; And aforesaid join card rib and pushing-stopping wedged edge united two into one, on left side wall, establish the right-angled trapezium fin wide outside and narrow inside of evagination, the bottom surface of this trapezoidal fin and its width parallel with side wall surface is than the narrow 4～8mm of dovetail groove bottom width degree, during connection, the trapezoidal fin of one substrate, one side is inserted a substrate dovetail groove and both oblique girdle planes and bottom surface are touched mutually in addition, and the thrust pin that inserts through perforate at the bottom of the dovetail groove is fixed between the right angle central plane of dovetail groove and trapezoidal fin.
