Detailed Description

The present invention is illustrated in with reference to the following examples, which are not intended to be limiting.

single spandrel girder of no computer lab elevator, including the roof beam body 10, this embodiment roof beam body 10 adopts H shaped steel, the inslot of H shaped steel both sides all is equipped with bending resistance reinforcing plate 15, the upper end of roof beam body 10 welds the frame bottom plate 11 that is connected with hauler and fag end combination, the lower surface at both ends of roof beam body 10 is equipped with mounting panel 12, mounting panel 12 below is equipped with shock pad 20, the base 30 of fixing on the wall body is equipped with below shock pad 20, base 30 is L type structure, limit of base 30 sets up in the preformed hole of wall body, the other limit of base 30 sets up on the wall body facade, be equipped with middle reinforcing plate 13 between roof beam body 10 and the frame bottom plate 11, middle reinforcing plate 13 is big end down's trapezoidal, be used for strengthening the part that supports frame bottom plate 11 and hang out roof beam body 10, be equipped with marginal reinforcing plate 14 between roof beam body 10 and mounting panel 12, marginal reinforcing plate 14 is big end down's trapezoidal, be used for strengthening the.

The mounting plate 12 and the shock pad 20 are welded on site, the shock pad 20 comprises an upper side plate 21, a rubber pad 22 and a lower side plate 23 which are arranged from top to bottom, and the upper side plate 21 is longer than the lower side plate 23. The number of the single-sided cushion 20 is 2 or 3, depending on the load, and 3 in the present embodiment. The 3 shock-absorbing pads are symmetrically arranged about the beam body 10. The rubber pad 22 is a cuboid with a concave side surface.

The lower part of the shock pad 20 is installed on the base 30 through bolts, transverse plates and vertical plates of the base 30 are T-shaped, the transverse plates and the vertical plates on the side are lapped on a wall body of a reserved hole, and reinforcing ribs are fixed between the transverse plates and the vertical plates on the side, and the vertical plates are fixed on the wall body through expansion bolts.

The working principle is as follows:

the utility model discloses a main part is single girder steel, and all the other spare parts have avoided local area part too much, the too big problem of volume along girder steel length direction evenly distributed moreover. Therefore, the utility model discloses easily processing, holistic volume is even and slightly little, and hoist and mount and adjustment position are all very convenient in the well. And simultaneously, the utility model discloses a bearing of vertical direction is realized at the both ends of girder steel, realizes antitorque commentaries on classics through mounting panel 12 and base 30, therefore need not pour the concrete reinforcement, and regardless of the installation in earlier stage or the adjustment in later stage, it is all very convenient. Moreover, the utility model discloses a shock pad 20 sets up the downside at the girder steel, and then reduces the distance of girder steel lower extreme to well roof board, and the top layer space that just also reduces, reduces the requirement of building. Furthermore, the utility model discloses a middle reinforcing plate 13 and edge reinforcing plate 14 strengthen frame bottom plate 11 and mounting panel 12, guarantee structural strength to this supports the design of single roof beam. The structure of the two reinforcing plates is optimized for stress distribution, and weight can be reduced with little influence on the structure.

The upper side plate 21 of the shock pad 20 and the mounting plate 12 are both welded on site, the longer upper side plate 21 of the shock pad 20 is more convenient to weld, and the problem that the position deviation of the bearing steel is difficult to adjust due to the deviation of the actual size of a well and the size of a civil engineering drawing can be solved.

The utility model discloses add 3 shock pads 20 in every side, because the vibration that the hauler produced when absorbing the elevator operation, effectively reduce and transmit the vibration in the building and on the car respectively through well wall body and wire rope, the noise of personnel's impression in the building reduces, and the elevator passenger takes the elevator comfort and has also strengthened. More importantly, the 3 shock-absorbing pads 20 are arranged in a manner that the requirements on the depth of the prepared hole are low, and the shock-absorbing pads can be spread in the width direction of the steel beam to improve the torsion resistance.

Rubber pad 22 of shock pad 20 is in the operating mode of pressurized, and the side can be outwards outstanding, the utility model discloses a predetermine the side of indent, can avoid the problem that the too outstanding easy ageing fracture of stress concentration that leads to behind the conventional straight side pressurized.

The utility model discloses according to well and load, optional dress bending-resistant reinforcing plate 15 advances step improvement bending resistance and antitorque commentaries on classics ability.
