Traffic sign board with hollow layout and design method thereof

Abstract

The invention discloses a traffic sign board with a hollow layout and a design method thereof. The traffic sign board comprises a sign board body and a stand column. The lower end of the stand column is connected with the column foot through a flange plate. The signboard body and the stand column are connected through a plurality of cross beams. The signboard main body is provided with a hollow part. The design method comprises the steps of load calculation, design calculation of the cross beams, design calculation of the stand column, connection of the stand column and the cross beams and checking calculation of the strength of the column base. The number and the size of the rod pieces and the foundations can be effectively reduced, the wind load of the sign is effectively reduced, and the traffic sign board and the method can be applied to the rod pieces and the foundations of roads and squares of various grades.

Description

technical field

[0001] The invention relates to the technical field of traffic sign board manufacturing, in particular to a traffic sign board with a hollowed-out layout and a design method thereof. Background technique

[0002] With the increasing complexity of the road traffic system, people's requirements for the convenience of traffic travel are increasing, so the demand for the perfect layout of traffic signs is increasing.

[0003] The size of the traffic layout is based on the design speed and the number of fonts, and the combination of words and signs according to certain rules. Usually, the guide signs in the city need to display more content, and the layout signs are larger. Usually the layout of guide signs is several square meters to tens of square meters. The huge layout is subject to large wind loads, and according to structural calculations, the dimensions of the rods and foundations are relatively large.

[0004] Therefore, how to reduce the size of rods a...

Embodiment 1

[0093] Such as figure 1 and Figure 3 to Figure 5 As shown, the traffic sign board with a hollow layout includes a sign board main body 1 and a column 2; the lower end of the column 2 and the column foot 3 are connected by a flange;

[0094] Wherein, the main body 1 of the signboard is provided with a hollow.

[0095] Such as image 3 As shown, in some embodiments, the hollow is in the shape of a stroke, that is, a through hole that occupies more than 150% of the main body of the signboard and is completely connected;

[0096] The hollowing out divides the main body 1 of the signboard into two plates which are connected into one body through a fixed connection.

[0097] In some embodiments, the fixed connection is welding.

[0098] Such as Figure 4 As shown, in some embodiments, the hollowing includes more than two through holes penetrating through both sides of the main body 1 of the signboard.

[0099] In some embodiments, the through holes are circular holes, polygon...

[0172] Take 50% of the hollowness as an example for calculation.

[0173] 1) Calculation of wind load

[0174] ① Sign wind load

[0175] f wb =1.04×1.39A 标 kN=1.45A 标 kN=9.135kN

[0176] ② Column wind load

[0177] f wp =0.693×1.39A 柱 kN=0.963A 柱 kN = 2.754kN

[0178] ③ Wind load on exposed beams

[0179] f wh =0.693×1.39A 梁 kN=0.963A 梁 kN = 0.202kN

[0180] 2) Calculation of 3F rod mark member

[0181] The specification of the column of the 3F pole sign is D325-12mm, the height is 8800mm, the material is Q355B, and the density is 78.5kN / m3. Alloy plate, the mass per unit area of ​​sign plate is 13.26kg / ㎡.

[0182] Logo layout gravity: G 1 =A*W 1 *g*1.1=0.901(KN);

[0183] Beam layout gravity: G 2 ==5.054(KN);

[0184] Column Gravity: G 3 =8.787(KN).

[0185] The total gravity of the upper structure of the sign is G=G 1 +G 2 +G 3 = 14.742 (KN).
