Billboard unitized construction bracing frame
Technical field
The utility model relates to the support system of billboard, what be specifically related to is billboard unitized construction bracing frame.
Background technology
Along with the fast development in city, the increase of vehicular traffic, original road can not satisfy the needs of urban development; Setting up viaduct has become the inexorable trend of urban development, as the billboard of road both sides, is the effective ways of transmission information; Billboard supports through support column, and billboard is fixed on the top of support column, but mostly the supporting construction of present billboard is steel construction single supporter system; Antenna height is low; If reach the height of the viaduct of 30-40 rice, steel tube section is long-pending to be needed resist very greatly wind and makes the moment of flexure that produces at the bottom of the support column, causes waste and structure unreasonable of material.
Summary of the invention
The purpose of the utility model provides billboard unitized construction bracing frame, and it is used to solve existing billboard steel construction single supporter is the low problem of antenna height.
The utility model solves the technical scheme that its technical matters adopted: the support column of this billboard unitized construction bracing frame is built-in steel truss concrete built-up pillar; Built-in steel truss concrete built-up pillar is formed by built-in steel truss and concrete depositing together; Built-in steel truss extends out from built-in steel truss concrete built-up pillar upper end and is fixedly connected with billboard, and the capital billet is set between the upper surface of built-in steel truss concrete built-up pillar and the billboard.
Support column is two in the such scheme, and the built-in steel truss that two support columns upper end extends out is fixed together with the billboard of a rectangle simultaneously, and two support columns are outward-dipping along symmetry on the short transverse, can reduce floor area like this.
Support column is three in the such scheme, every support column upper end extend out built-in steel truss each be fixed together with a billboard, three billboards join end to end connect constitute triangular prism shaped.
The utlity model has following beneficial effect:
1, the utility model vertical bearing capacity is big, and laterally bending resistance is strong, and antenna height is high.
2, the built-in steel truss in the utility model can be prefabricated in the factory, the on-the-spot installation, and speed of application is fast.
3, the built-in steel truss concrete built-up pillar in the utility model can support as interim at the top when billboard is installed, and helps the accurately in place of billboard.

1 built-up pillar, 2 built-in steel truss 3 billboards 4 capital billets.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation:
As shown in Figure 1; The support column of this billboard unitized construction bracing frame is built-in steel truss concrete built-up pillar 1; Built-in steel truss concrete built-up pillar 1 is formed with concrete depositing by built-in steel truss 2 together; Built-in steel truss 2 extends out from built-in steel truss concrete built-up pillar 1 upper end and is fixedly connected with billboard 3, between the upper surface of built-in steel truss concrete built-up pillar 1 and the billboard 3 capital billet 4 is set.Adopt built-in steel truss concrete built-up pillar 1 can play the certain protection effect to the steel in the built-up pillar, the built-in steel truss 2 that extends out from built-in steel truss concrete built-up pillar 1 top is convenient to weld with the billboard member.
Support column is two in this embodiment, and the built-in steel truss 2 that two support columns upper end extends out is fixed together with the billboard 3 of a rectangle simultaneously, and two support columns are outward-dipping along symmetry on the short transverse, can reduce floor area like this.
Shown in Figure 2 is the structural representation of the another kind of embodiment of the utility model; Like figure; This billboard unitized construction bracing frame and difference shown in Figure 1 are; Support column is three, every support column upper end extend out built-in steel truss 2 each be fixed together with a billboard 3, three billboards 3 join end to end connect constitute triangular prism shaped.Other structure is with shown in Figure 1 identical.
