The following describes a steel beam fixing structure 100 according to an embodiment of the present invention with reference to FIGS. 1-8 .

According to the steel beam fixing structure 100 according to the embodiment of the present invention, as shown in FIGS. 1-5 , the steel beam fixing structure 100 includes an anchor rod 1 , a welding bracket 2 , a steel beam 3 and a bolt 4 . The welding bracket 2 has side plates 21, flat plates 22, vertical plates 24 and stiffening ribs 25. The flat plate 22 is connected to one side of the side plate 21 , the vertical plate 24 is vertically arranged above the flat plate 22 and connected to the side plate 21 , the vertical plate 24 is provided with a first connecting hole 241 , and the rib 25 is located at the level of the vertical plate 24 . One side is connected with the vertical plate 24 and the flat plate 22 respectively. The bolt 1 is suitable for being anchored on the well wall 200 , the side plate 21 is arranged along the well wall 200 , and the side plate 21 is connected with the bolt 1 to be fixed on the well wall 200 . The steel beam 3 is arranged on the flat plate 22 and on the other side of the vertical plate 24 , and the steel beam 3 is provided with a second connection hole 321 . The bolts 4 pass through the first connecting hole 241 and the second connecting hole 321 respectively to connect the steel beam 3 and the welding bracket 2 .

The welding bracket 2 is a welding piece, and the side plate 21 , the flat plate 22 , and the vertical plate 24 are connected into one body by welding. When the steel beam fixing structure 100 is assembled, the welding bracket 2 is first fixed on the shaft wall 200 through the anchor rod 1, and then the steel beam 3 is placed on the welding bracket 2. 3 is fixedly connected with the welding bracket 2, and finally the steel beam 3 is clamped on the welding bracket 2 by the auxiliary clamp 5.

It should be noted that the bracket provides support for the steel beam at both ends of the steel beam, and is the support of the steel beam. Therefore, the strength of the bracket design and the quality of the on-site installation are directly related to the bearing capacity of the steel beam, which is particularly important in the lifting shaft. In recent years, the lifting capacity and lifting speed of mines have become higher and higher, which puts forward higher requirements for the installation of steel beams. The bracket that provides support for the steel beam is bound to increase the requirements to match the bearing capacity of the steel beam. The design innovation of the bracket should not only ensure that its design strength meets the requirements, but also ensure that its external dimensions should be coordinated with the size of the steel beam to meet visual safety. At the same time, it should also take into account the harsh working environment on site, and it should be easy to install and reduce labor. strength.

At present, in the prior art, the fixing of steel beams still mainly adopts the bracket structure of upper and lower angle steels. In this kind of structure, angle steels are arranged on the upper and lower sides of the steel beam as brackets. The implementation of this structure is: welding stiffening rib plates on the angle steel, opening corresponding bolt holes on the steel beam and the angle steel respectively, and installing the anchor rods during installation. To the well wall, then install the lower angle steel, fix the steel beam, bolt the steel beam to the lower angle steel, install the upper angle steel, and finally bolt the steel beam to the upper angle steel. Since the steel beam needs to be aligned with the upper angle steel and the lower angle steel during installation, this kind of structure is difficult to align the holes on site, the installation work intensity is high, and the installation quality cannot be guaranteed. The size of the reaming hole is also limited. In severe cases, the pallet will be burned out, which will seriously reduce the support capacity of the pallet. Therefore, this kind of structure can no longer meet the requirements of the bearing capacity of the steel beam, nor does it meet the visual safety. In some structures with upper and lower angle steel brackets, since they cannot be connected by bolts, they are installed by welding, that is, the upper and lower angle steels are anchored on the well wall, and the steel beams are directly welded to the upper and lower angle steels, which will provide maintenance and replacement of the brackets and steel beams in the future. bring certain difficulties. In short, the upper and lower angle steel brackets cannot guarantee and provide the strength required for the installation of fixed nodes in the tank channel, increase the installation work strength, weaken the bearing capacity of the steel beam, affect the operation of the lifting container and reduce the lifting task of the shaft. When the steel beam is subjected to accidental events, it cannot play its due role and is prone to damage.

With the development of technology and the needs of mine production, the running speed of the lifting container is getting faster and faster, which puts forward higher and higher quality requirements for the design, installation, maintenance and replacement of steel beams. The fixation of the steel beam should not only ensure that it will not be damaged during normal stress, but also ensure that it will not fail when accidental events occur, and continue to play its role. In this application, a welding bracket 2 is used to replace the angle steel bracket in the existing solution. The welding bracket 2 has a side plate 21 , a flat plate 22 , a vertical plate 24 and a stiffening rib 25 , and the welding bracket is supported by the stiffening rib 25 . 2. The overall stiffness and strength are improved, so the bearing capacity of the steel beam 3 is further improved. Moreover, the welding bracket 2 is formed by welding the side plate 21, the flat plate 22 and the vertical plate 24. In terms of size, the three plates can be completely selected according to the actual needs. The size of the welding bracket 2 can be determined according to the design strength and The opening requirements are determined, which avoids the trouble of large-scale reaming on site. The arrangement of the welding bracket 2 eliminates the need to arrange brackets above and below the steel beam, and overcomes the problem of alignment of the upper and lower brackets and the anchor rod. Therefore, the steel beam fixing structure 100 using the welding bracket 2 is matched with the large-load steel beam in terms of bearing capacity, external dimensions, and visual safety, which ensures the supporting capacity of the steel beam. In a word, the welding bracket 2 is simple in structure, convenient in processing, low in technical requirements, and low in implementation cost, which not only reduces labor intensity, facilitates installation, speeds up installation progress, but also improves the strength of fixed joints of steel beams.
