1-6, a fall arrest mounting arrangement 10 for a steel frame construction passenger footbridge, comprising: the mounting steel frame 100, the metal substrate 110, the decorative mounting plate 120, the decorative material piece 130, the connecting piece 140 and the fixing piece 150; the two ends of the metal substrate 110 are L-shaped welding parts 111, and the metal substrate 110 is provided with a first mounting hole; the decorative mounting plate 120 is provided with a second mounting hole and a third mounting hole, and the first mounting hole and the second mounting hole are distributed correspondingly; the decorative material piece 130 is provided with a mounting through hole; the mounting steel frame 100 is used for fixing a pedestrian bridge; the welding parts 111 at the two ends of the metal substrate 110 are welded and fixed to the steel frame, so that the metal substrate 110 is parallel to the side surface or the top surface corresponding to the mounting steel frame 100; the fixing member 150 passes through the mounting through hole and the second mounting hole, and fixes and arranges the decorative material member 130 on the decorative surface of the decorative mounting plate 120; the connecting members 140 penetrate the third mounting holes and the first mounting holes to fix the plurality of decorative mounting plates 120 to the surface of the metal substrate 110 in parallel.

As shown in fig. 3 and 4, two ends of the decorative mounting plate 120 are provided with bent portions 121, and the bent portions 121 are U-shaped; the third mounting hole is arranged on one side surface of the bending part 121 departing from the decorative surface and aligned with the first mounting hole; the connecting member 140 is a bolt, and the bending portion 121 has a bending cavity with a thickness greater than that of the bolt and the nut. After the decorative mounting plate 120 is mounted on the metal substrate 110, the surface for mounting the decorative material 130 is not obstructed by the connecting member 140, so that the bolt is completely hidden inside the mounting structure, and a larger and smoother mounting plane can be obtained.

When the decoration material piece 130 is installed on the decoration installation plate 120, the installation through hole of the same decoration material piece 130 corresponds to the second installation hole of the same decoration installation plate 120. Because the decorative mounting plate 120 and the decorative material member 130 are attached to each other at multiple points, the decorative mounting plates 120 are attached to each other and are affected by temperature uniformly; however, if one piece of the decorative material 130 is fixed to two or more pieces of the decorative mounting plates 120 at the same time, once the relative position between the decorative mounting plates 120 changes due to temperature, the piece of the decorative material 130 connected to the plurality of pieces of the device mounting plates at the same time may be damaged or dropped; and the problem can be well solved by adopting the installation mode.

Specifically, the fixing member 150 is a self-tapping screw.

The decorative material 130 is made of a resin material, and the decorative mounting plate 120 is an aluminum plate. Specifically, the decorative material can be a resin tile, and the specific shape can be set according to the requirement, for example, the decorative material is correspondingly set to be an arc shape or a cylindrical shape at the position of a cornice at the top of a building decorative area; the side plane of the building decoration area is arranged to be flat. The resin material can make the pedestrian overpass lighter on one hand, and on the other hand, the pedestrian overpass can not cause safety accidents as ceramic tiles even if the pedestrian overpass falls; the decorative mounting plate 120 is made of aluminum plates, so that the overall weight of the pedestrian overpass can be further reduced, and the bearing capacity is ensured.

An expansion joint is reserved at the splicing position between the adjacent decorative material pieces 130, and the width of the expansion joint is 5-20 mm. Because different materials change along with the environmental temperature, the extension degree is different; when the specific decorative material piece 130 is made of a resin material, the change is not obvious as that of an aluminum plate; in order to avoid that the fitting contact between the decorative material pieces 130 is easily pulled and damaged by the aluminum plate, the expansion joints are arranged; the too large width of the expansion joint influences the integral effect of architectural decoration, and the too small width of the expansion joint does not overcome the effect of expansion with heat and contraction with cold; the method is set in a specific range, and can be properly adjusted in the range according to different climatic and geographic environments of the building; both the structural stability and the optimum decorative effect can be ensured.

And neutral silicone sealant is filled in the expansion joint. Can make to combine between the decorative material piece 130 inseparabler, let the whole decorative effect of the architectural decoration face of formation better, can prevent wind moreover and keep off rain.

A pedestrian overpass, which is a steel frame structure pedestrian overpass, comprising: a stair walkway construction, a cross-street walkway construction and an elevator construction 210; the anti-falling installation structure is characterized in that the anti-falling installation structure 10 is installed on a stair channel structure, a cross-street channel structure and/or an elevator structure 210, and the installation steel frame 100 is welded and installed on a steel frame structure arranged on the pedestrian bridge. The pedestrian overpass can be provided with the corresponding anti-falling mounting structures 10 at corresponding positions according to the requirements of the architectural style, so that various required architectural decorations can be stably mounted on the pedestrian overpass with the steel frame structure; the shape of the building device is determined by the shape of the decorative material 130, the color and the specific installation position of the installation steel frame 100, the metal substrate 110 and the decorative installation plate 120, which can be freely set according to actual needs.

As shown in fig. 5 and 6, the stair pathway structure includes a stair stringer 220 and a stair post 221 supported at the bottom of the stair stringer 220; the cross-street channel structure comprises a channel main beam 230, and a main pier 231 and an auxiliary pier 232 which are supported at the bottom of the channel main beam 230; the stair upright column 221 is connected with the bottom of the stair beam 220 through a bolt, and a gasket 240 is arranged between the stair upright column and the stair beam; the auxiliary bridge pier 232 is connected with the bottom of the channel main beam 230 through a bolt, and a gasket 240 is arranged between the auxiliary bridge pier 232 and the channel main beam; the main pier 231 and the bottom of the channel girder 230 are tightly fixed through bolts. Because the stability of the whole pedestrian overpass needs to be maintained by the main bridge piers 231 arranged at the two ends, the connection mode of the main bridge piers 231 and the channel main beam 230 adopts the direct fixation of bolts and is not provided with the gaskets 240; the middle parts of the stair girders 220 and the main passage girders 230 are easy to shake under pressure, and the shake is within an allowable range; however, since the vibration easily causes the collision between the subsidiary pier 232 and the main channel beam 230 or between the stair post 221 and the stair beam 220, and thus generates excessive noise, it is necessary to add the spacer 240 at a corresponding position to reduce noise.

The gasket 240 is a rubber gasket 240 and/or a polytetrafluoroethylene gasket 240, and both the rubber gasket 240 and the polytetrafluoroethylene gasket 240 have good corrosion resistance and buffering performance, so that the service life of the pedestrian overpass can be prolonged, and the stability of the pedestrian overpass can be improved.
