Meanwhile, when the displacement is generated between the building main body 100 and the corridor support, the protective cover plate 14 can be pushed open to move, the displacement is not blocked, and damage to building surface layers on two sides can be reduced.
Still further, be equipped with between the wall that support bottom plate 11 with pre-buried steel sheet 125 place sunken in the water drainage canal 15 in supporting platform 10, water drainage canal 15 with the protection apron 14 subtend sets up, can follow rainwater, washing water, the orderly downpipe of discharging of dust infiltration from protection apron 14 both sides also makes support bottom plate 11 and the sliding plate 20 of installing between support bottom plate 11 and supporting platform 10 all be higher than peripheral building main part 100, prevents that the water in the vestibule support, mud from corroding support bottom plate 11 to promote the durability that the vestibule support used.
Example 2: the fixation is performed by a three-hole method 41 described in embodiment 1, namely: the first pin shaft 121 and the second pin shaft 122 penetrate through the limiting narrow hole 131 and the limiting wide holes 132 arranged on two sides of the limiting narrow hole 131, and the mode can be generally suitable for the corridor 200 with the width of 2-5 meters. When the gallery 200 is wider and heavier, the gallery support may be fixed in a five-hole 42 or seven-hole 43 manner, i.e.: the spacing narrow holes 131 and spacing wide holes 132 are arranged on the support platform 10 on the larger building body 100, as shown in fig. 2, the mechanism is still consistent with the three-hole mode 41, namely: the center of the support base plate 11 is provided with a narrow long hole to limit the rotation center, two sides of the support base plate adopt a limit wide hole 132, and meanwhile, the same limit narrow hole 131 and limit wide hole 132 are arranged in the axial direction of the first pin shaft 121 to carry out multiple fixing on the corridor support.
