Problems solved by technology

However, due to the passing rate requirements of modern traffic, the width of the bridge deck is becoming wider and wider. At this time, the double C hanging lug walking structure may not be able to support the hanging basket. Therefore, it is necessary to lay a special walking track on the beam section that has been poured.

Embodiment 1

[0034] A new type of super-wide front fulcrum dragline hanging basket thrust device of the present invention is installed on the upper surface of the bridge, which is suitable for the running mechanism of the upper sliding track. The thrust device of this walking mode needs to be provided with a reserved hole on the bridge surface , the first fixed steel bar 203, the second fixed steel bar 205, and the third fixed steel bar 404 can also be directly embedded, and the first fixed steel bar 203 and the second fixed steel bar 205 embedded in the guardrail can be used as guardrail reinforcements in the later stage. The third fixed steel bar 404 in the middle needs to be cut off and roughened.

[0035] The specific structure is as follows:

[0036] refer to Figure 1-5 , a new ultra-wide front fulcrum drag cable hanging basket thrust device, including support blocks 2 arranged at the guardrails on both sides of the poured bridge deck 1, fixed support 4 arranged at one side of the end...

Embodiment 2

[0039] A new type of ultra-wide front fulcrum guy cable hanging basket thrust device of the present invention is installed on the lower surface of the bridge, which is suitable for the running mechanism of the lower sliding track. There are not many restrictions on the thrust device of this walking mode, and the reserved hole can Filling through supplementary pouring; if the method of pre-embedded steel bars is adopted, the pre-embedded steel bars can be processed by chiseling and supplementary pouring, and can also be used as reinforcement binding for expansion joints;

[0040] The slight difference in structure between this embodiment and Embodiment 1 is that, when it is installed on the lower surface of the bridge, it is necessary to fix the locking frame 403 on the L-shaped support plate 402 and the anti-skid plate 401 by means of bolt filling welding to form an inaccessible The dismantled fixed support 4.

[0041] According to the specific structure of the embodiment 1-2,...

Abstract

The invention discloses a novel ultra-wide front fulcrum cable-stayed hanging basket thrust device which comprises a supporting block, a fixed support and a movable support, wherein the supporting block is provided with a penetrating cross rod, a horizontal square steel column, a first fixing steel bar and a first supporting foot; the fixed support comprises an antiskid plate, an L-shaped supporting plate and a lock catch frame, and a rectangular groove of a bottom plate of the lock catch frame is riveted with a female head lock catch; a rectangular groove of a top plate of the movable supportis riveted with a male head lock catch, a U-shaped plate of a female head lock catch and a U-shaped plate of the male head lock catch are clamped together to form a rectangular frame structure, and ahorizontal square steel column is movably sleeved with the rectangular frame structure. The invention further provides a corresponding use method. The female head lock catch and the male head lock catch with simple U-shaped frame structures are adopted; clutch locking and unlocking can be achieved only through forward and reverse sliding of the walking mechanism, namely, the whole walking-thrust-unloading work is completed, the mounting, fixing and dismounting process is simple, convenient and clear, the laying process of the cable-stayed hanging basket embedded part is greatly shortened, andthe hanging basket pouring construction speed of the cable-stayed bridge is increased.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a novel ultra-wide front fulcrum stay cable hanging basket thrust device. Background technique [0002] The construction of the front fulcrum stay cable hanging basket is widely used in the bridge construction process of the cable-stayed bridge. For the bridge deck with a small width, the double C hanging lug walking structure can be used. However, due to the passing rate requirements of modern traffic, the width of the bridge deck is becoming wider and wider. At this time, the double C hanging lug walking structure may not be able to support the hanging basket. Therefore, it is necessary to lay a special walking track on the beam section that has been poured. . [0003] In the construction process of the front fulcrum stay cable hanging basket of the ultra-wide bridge deck, it is generally necessary to lay more than 4 special walking tracks on the beam section that ...
