DETAILED DESCRIPTION

[0025] Please refer to Figures 1 to 6 The utility model provides a kind of anti-falling support mounting structure of elevator shaft steel structure frame, which comprises a support plate 11, a vertical support 12, a horizontal support 13, a stud 14, a nut 15, a connecting angle steel 16 and an adjusting pad 17.

[0026] The support plate 11 is rectangular, with two vertical supports 12 and two horizontal supports 13 welded on the front face. The two vertical supports 12 are welded vertically on the edges of the left and right sides of the front face of the support plate 11, and the two horizontal supports 13 are welded horizontally near the upper and lower ends of the vertical supports 12, forming a rectangular frame with the vertical supports 12 and the horizontal supports 13 to increase the structural strength.

[0027] A stud 14 is welded at the center of the front face of the support plate 11 for connection with the anti-falling support 2 and locked and fixed by a nut 15.

[0028] Four connecting angle steels 16 are welded on the back face of the support plate 11 in a rectangular array. Each connecting angle steel has an L-shaped cross section, and adjacent two connecting angle steels 16 are arranged back to back. Each connecting angle steel 16 has a first mounting hole 161 in the horizontal and vertical directions.

[0029] The adjusting pad 17 has two second mounting holes 171 near the ends for connection with the first mounting holes 161 by bolts, so that the adjusting pad 17 is connected to the adjacent two connecting angle steels 16.

[0030] Preferably, the second mounting holes 171 are counterbores, and the bolt caps are flush with the surface of the adjusting pad 17 after connection to avoid interference.

[0031] The adjusting pad 17 has multiple third mounting holes 172 for connection with the vertical columns 31 or horizontal beams 32 of the steel structure frame 3. In this embodiment, the third mounting holes 172 are waist holes, and in other embodiments, the third mounting holes 172 can also be a row of round holes to fine-tune the installation position of the anti-falling support 2.

[0032] It should be noted that the distance between the left and right rows of the four connecting angle steels 16 in the utility model is slightly greater than the width of the vertical columns 31 of the steel structure frame 3, and the distance between the upper and lower rows is slightly greater than the width of the horizontal beams 32. The vertical columns 31 and the horizontal beams 32 of the steel structure frame 3 have evenly distributed connecting holes. Considering the structural strength, the holes in the vertical columns 31 and the horizontal beams 32 should not be too dense.

[0033] When the first mounting hole 161 is directly aligned with the hole position on the column 31 or the beam 32, the installation of the adjusting pad 17 is not required, and the installation is completed by directly screwing the bolt between the first mounting hole 161 and the column 31 or the beam 32 and adding the gasket.

[0034] When the first mounting hole 161 cannot be directly aligned with the hole position on the column 31 or the beam 32, the adjusting pad 17 is installed, and the connection and the fine adjustment of the position are achieved by screwing the bolt between the third mounting hole 172 and the column 31 or the beam 32.

[0035] In addition, when the fall arrest support 2 needs to be installed at the intersection of the column 31 and the beam 32, since the adjusting pad 17 will interfere with the column 31 or the beam 32, a special hole position is designed for direct connection with the first mounting hole 161 at this position.

[0036] The utility model discloses simple structure, convenient to use, and the universality is strong, has improved the convenience of construction and maintenance, easy to process, low cost, is suitable for promotion.

[0037] The above is only the preferred embodiment of the utility model, and does not limit the utility model in any form, and the technical content disclosed above is used to make some simple modifications, equivalent changes or modifications by the person skilled in the art, which falls within the protection scope of the utility model.
