A steel beam fixing structure 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 8.
According to the utility model discloses girder steel fixed knot constructs 100, as shown in fig. 1-5, girder steel fixed knot constructs 100 includes: anchor 1, welding bracket 2, girder steel 3 and bolt 4. The welding carriage 2 has side plates 21, flat plates 22, risers 24 and a ribbed rib 25. Dull and stereotyped 22 is connected in one side of curb plate 21, and the riser 24 is vertical to be set up in dull and stereotyped 22 top and link to each other with curb plate 21, is equipped with first connecting hole 241 on the riser 24, and the rib 25 that adds is located riser 24 horizontal one side and links to each other with riser 24, dull and stereotyped 22 respectively. The anchor rods 1 are adapted to be anchored to the borehole wall 200 with the side plates 21 disposed along the borehole wall 200, the side plates 21 being connected to the anchor rods 1 for securement to the borehole wall 200. The steel beam 3 is arranged on the flat plate 22 and located on the other horizontal side of the vertical plate 24, and a second connecting hole 321 is formed in the steel beam 3. Bolts 4 pass through the first and second connection holes 241 and 321 to connect the steel beam 3 and the welding bracket 2, respectively.
The welding bracket 2 is a welding part, and the side plate 21, the flat plate 22 and the vertical plate 24 are connected into a whole by welding. Girder steel fixed knot constructs 100 is when the assembly, earlier with welding bracket 2 through stock 1 be fixed in the wall of a well 200 on, then put up girder steel 3 on welding bracket 2, erect with bolt 4 with girder steel 3 and welding bracket 2 fixed connection after counterpointing, finally with supplementary fastener 5 with girder steel 3 card on welding bracket 2.
It should be noted that the bracket provides a supporting function for the steel beam at both ends of the steel beam, and is a support of the steel beam. The strength of the bracket design and the quality of the field installation quality are directly related to the bearing capacity of the steel beam, and the bracket design is particularly important in lifting the vertical shaft. In recent years, mine lifting capacity and lifting speed are higher and higher, which puts higher requirements on installation of steel beams. Brackets that provide support for the steel beams are also required to match the load bearing capacity of the steel beams. The design innovation of bracket not only will guarantee that its design strength meets the demands, also need guarantee simultaneously that its overall dimension will coordinate with the girder steel size, satisfies visual safety, also needs the abominable operational environment in field of considering simultaneously, will simple to operate, reduces intensity of labour.
At present, the steel beam is still fixed mainly by adopting a bracket structure of upper and lower angle steels in the prior art. This kind of structure all sets up the angle steel as the bracket on the girder steel downside, and the embodiment of this structure is: and welding stiffening rib plates on the angle steel, respectively forming corresponding bolt holes in the steel beam and the angle steel, mounting the anchor rods on the well wall during mounting, then mounting the lower angle steel, fixing the steel beam, connecting the steel beam on the lower angle steel by using bolts, then mounting the upper angle steel, and finally connecting the steel beam on the upper angle steel by using bolts. The hole is not only needed to be aligned with the upper angle steel, but also needs to be aligned with the lower angle steel when the steel beam is installed, the hole is difficult to align on the site of the structure, the installation operation intensity is high, the installation quality can not be guaranteed, the hole is usually expanded by electric welding on the site, the hole expansion size is limited due to the size influence of the angle steel, serious persons can burn the supporting plate, and the supporting capacity of the supporting plate is seriously reduced. Therefore, the structure can not meet the requirement of the bearing capacity of the steel beam and the visual safety. In some structures adopting the upper and lower angle steel brackets, due to the fact that bolt connection cannot be achieved, welding installation is adopted, namely the upper and lower angle steels are anchored on a well wall, and steel beams are directly welded on the upper and lower angle steels, and certain difficulty is brought to maintenance and replacement of the rear brackets and the steel beams. In a word, the upper and lower angle steel brackets can not guarantee and provide the required intensity of cage guide installation fixed node, increase installation working strength, weaken the bearing capacity of girder steel, influence the operation that promotes the container and reduce the promotion task of shaft. When the steel beam is subjected to an accidental event, the due function of the steel beam cannot be exerted, and the steel beam is easy to damage.
Along with the development of the technology and the requirement of mine production, the operation speed of the lifting container is faster and faster, so that higher and higher quality requirements are provided for the design, installation, maintenance and replacement of the steel beam. The steel beam is fixed, so that the steel beam is not damaged when stressed normally, and is not invalid when an accidental event occurs, and the steel beam continues to play a role. This application has adopted welding bracket 2 to replace the angle steel bracket among the current scheme, and welding bracket 2 has curb plate 21, flat 22, riser 24 and adds muscle rib 25, and welding bracket 2 global rigidity and intensity obtain promoting under adding holding of muscle rib 25, consequently also can further promote the bearing capacity of girder steel 3. And the welding bracket 2 is formed by welding and connecting the side plate 21, the flat plate 22 and the vertical plate 24, and three plate bodies in size can be selected to be in proper size according to actual needs, namely the size of the welding bracket 2 can be determined according to design strength and hole opening requirements, so that the trouble of large hole expansion on site is avoided. The arrangement of the welding bracket 2 avoids the need of arranging brackets below the upper part of the steel beam, and overcomes the difficult problem of alignment of the upper bracket, the lower bracket and the anchor rod. Therefore, the steel beam fixing structure 100 of the welding bracket 2 is matched with a steel beam with a large load in terms of bearing capacity, external dimension and visual safety, and the bearing capacity of the steel beam is ensured. In a word, welding bracket 2 simple structure, processing is convenient, and technical requirement is low, realizes with low costs, has both reduced intensity of labour, and simple to operate for the installation progress has improved girder steel fixed node's intensity again.
