Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the utility model will be understood by those skilled in the art according to the specific circumstances.

As shown in fig. 1 to 3, the planned road set-up is combined with the basement roof in order to be able to make full use of the underground space. According to the planned municipal road practice, the basement roof needs to be partially lowered, and the utility model provides a steel trestle temporary road installed on the lowered area so as to meet the use requirement of the temporary road, wherein the steel trestle temporary road comprises the following components: the landing stage bearing structure body 1 and the pavement plate 2, landing stage bearing structure body 1 plays the effect of bearing and stability, and pavement plate 2 is used for the stroke bridge floor to the vehicle passes through, landing stage bearing structure body 1 bottom accessible fixed connection or detachable connection's mode is installed at building body structure 100 top, and fixed connected mode is slightly complicated when dismantling, and detachable connected mode is convenient for later stage dismantle, does benefit to steel recycling, also is convenient for the holistic reuse of structure simultaneously, and is a plurality of pavement plate 2 is followed landing stage bearing structure body 1 is adjacent to be laid on the landing stage bearing structure body 1, just landing stage bridge floor height that pavement plate 2 constitutes is not less than the degree of depth of building body structure 100 top landing low zone.

The further improvement is that the trestle supporting structure main body 1 comprises a reticular structure 11 formed by criss-cross of a plurality of bearing beams 111 and a plurality of bearing columns 112, the bearing columns 112 are arranged in two rows according to the position and the direction of the trestle setting designed in advance, after the bearing columns 112 are fixedly arranged, the reticular structure 11 is arranged at the top ends of the bearing columns 112, the trestle supporting structure main body 1 is formed, and the pavement plate 2 is laid on the reticular structure 11.
