The isosceles trapezoid backing plate is isosceles trapezoid hot rolled steel plate.
The thickness of the isosceles trapezoid backing plate is at least 8mm.The thickness of isosceles trapezoid backing plate should take 8 mm and more than,
It can guarantee that the weak component of strong node.
The width of the vertical fixing plate is equal to the horizontal range between the crimping of C-type steel both sides.
The beneficial effects of the utility model are：The fixing device for installing of cable testing bridge described in the utility model, including expansion
Bolt, C-type steel and fixed fastener.The fixing device for installing coordinates erection bridge using expansion bolt and C-type steel, then eliminates
The link of embedded iron component is carried out during civil engineering, the elevation location of direct basis design drawing requirement, is consolidated using expansion bolt
C-type steel is determined as crane span structure support, it is simple to operate, it is fixed, is pacified using fixed fastener between the trailing arm and C-type steel of crane span structure
Fill convenient and swift, easy to operate.
The expansion bolt is made up of nylon pin embolism and metallic screw；Uniformly be laid with the web of the C-type steel with
The mounting hole that metallic screw is engaged.Spheroid can be formed by twist ties in fixed wall using nylon bolt plug, produced " from spiral shell
Female effect ", it is solid and reliable, it is wide for the applicability of various wall.
Isosceles trapezoid backing plate is fixed with the bottom of C-type steel；Avoid C-type steel bottom that local buckling occurs, so as to avoid making
Destroyed into In-plane Instability；The bearing capacity and anti-seismic performance of C-type steel are enhanced, the cable testing bridge after guarantee installation is fixed is more firm
It is Gu stable.
The fixed fastener includes fixing bolt, horizontal reinforcing plates and the vertical fixing plate being connected with horizontal reinforcing plates.
Horizontal reinforcing plates are used to improve C-type steel in the critical load by distortional buckling in the case of curved.The wherein shape and C of horizontal reinforcing plates
The cross section of shaped steel matches, using with C-type steel cross-sectional form identical horizontal reinforcing plates, consolidation effect is best, distortion bend
The increase rate of bent Critical Bending Moment for strong axle more than 28%, for weak axle more than 35%.
The width of vertical fixing plate is not more than the horizontal range between the crimping of C-type steel both sides, and such design first can be with
Coordinating horizontal reinforcing plates well, second can facilitate trailing arm in follow-up cable testing bridge to the firm booster action of C-type steel itself
More stable and firm is fixed on vertical fixing plate.
Vertical fixing plate is provided with plate hole, and the plate hole matches with fixing bolt；Trailing arm so in cable testing bridge passes through
Fixing bolt and plate hole are fixed on vertical fixing plate, so as to be collectively forming complete cable testing bridge with expansion bolt and C-type steel.
Spring is connected with the plate hole of the vertical fixing plate between C-type steel web, so further strengthens firm hang down
The directly connection between fixed plate and C-type steel and the fastening of fixing bolt, and then make it that trailing arm and C-type steel are more firm, so as to
Ensure the overall stability of whole cable testing bridge.Wherein the line footpath of spring matches with the fixing bolt, so when trailing arm leads to
Cross fixing bolt through plate hole be fixed on vertical fixing plate when, spring can give trailing arm active force by fixing bolt simultaneously, protect
The balance of torque between card trailing arm, C-type steel and fixed fastener three, so as to keep the steadiness of whole cable testing bridge.
C-type steel is fixed on cable furrow bank using expansion bolt using the fixing device for installing of the cable testing bridge,
Eliminate welding sequence, while the installation of embedded iron component is carried out during without civil engineering, improve operating efficiency；Also avoid
For conventional mounting mode when carrying out the installation of crane span structure support, embedded iron member position is improper or concrete layer is blocked up can not find iron structure
Part and the phenomenon done over again occurs, and after design alteration occurs, dismantle more convenient.
Because without processes such as iron component embedded bracket welding, more traditional engineering method reduces by 3 welding machine configurations, it is contemplated that workmen
10 people, by taking the installation of 9FA combustion engine project combustion engine island district cable ditch crane span structure as an example, it is contemplated that 45 days durations.Compared with conventional mounting engineering method, sheet
Engineering method shortens 15 days durations, saves 3 welding machines：（45-30）=15 machine-teams, save artificial：（15×45）-（6×30）=495 works
Day, save expense and amount to 130950 yuan.
The installation of cable testing bridge is carried out using the fixing device for installing, relatively above-mentioned conventional mounting mode, is had following special
Point：
（1）It is not high to the requirement standard of Civil Specialities construction by the way of expansion bolt fixation；
（2）It is more fast, convenient in mounting bracket；
（3）Using the fixed form of expansion bolt, construction work amount is reduced, simplifies construction procedure；Simultaneously in crane span structure support
Installation procedure on, it is simpler compared to welding, be more convenient for operating because being fixed using expansion bolt；
（4）Either when support is installed, or when there is design alteration, the installation and removal of cable testing bridge and support
It is more convenient, it is more efficient.
In summary, the fixing device for installing can fundamentally solve the problems, such as to produce using traditional handicraft, construction party
Method technique is simple and convenient to operate, and greatly improves efficiency of construction；Avoid because embedded iron parts are uncomfortable and caused by do over again and cost
Wasting phenomenon；This process Installation and dismounting are simple, quick, and save engineering cost.This fixing device for installing is applied to have cable
The project of ditch design, therefore, it is suggested that in industry part is promoted.
