Description

Technical Field

[0001] This utility model relates to the field of box-type steel beam technology, specifically a box-type steel beam. Background Technology

[0002] Box-type steel beams are closed box-section beams made up of components such as top plate, bottom plate, web, transverse diaphragms, longitudinal diaphragms, and stiffening ribs, which are connected by full welding. Their name comes from their box-like shape. They have a hollow internal structure and are characterized by their wide and flat shape.

[0003] Publication No. CN222648566U discloses a box-type steel beam, belonging to the technical field of box-type steel beams. This utility model includes a first box-type steel beam body and a second box-type steel beam body. A support plate is movably connected to the right side of the first box-type steel beam body, and the support plate is movably connected to the second box-type steel beam body. When splicing the first and second box-type steel beam bodies, this utility model inserts the right side of the first box-type steel beam body and the left side of the second box-type steel beam body into a sleeve, aligning the first threaded groove with the first through-hole. This utility model uses a first bolt to sequentially pass through the first and second through-holes and then threadedly connect to the first threaded groove, thereby fixing the first and second box-type steel beam bodies. This utility model completes the splicing of the first and second box-type steel beam bodies by installing a reinforcing frame. This utility model has the advantages of easy splicing and good splicing effect.

[0004] The aforementioned patent addresses the shortcomings of existing box girder technology, which typically uses on-site welding to connect two box girders during on-site assembly. These welding methods suffer from defects, deformation, and fatigue at the weld joints due to issues with welding quality and construction efficiency, thus affecting construction speed and quality. However, this technical solution involves creating numerous threaded grooves and openings on the surface of the sleeve and positioning block, and then using bolts within these grooves and openings to connect the first and second box girder bodies to the sleeve. The large number of bolts, threaded grooves, and openings makes the splicing process extremely time-consuming, impacting the installation efficiency of the box girder. Therefore, this patent proposes a new box girder design to solve these problems. Utility Model Content

A second positioning block 6 is fixedly installed on one end surface of the second box-type steel beam 2. Two rectangular inserts 7 are fixedly installed on the surface of the second positioning block 6. Through holes 8 are opened on opposite sides of the rectangular sleeves 5 and inside the rectangular inserts 7. A placement groove 9 is opened on the upper surface of the steel beam connecting sleeve 3. A circular hole 10 communicating with the inside of the steel beam connecting sleeve 3 is opened on the inner surface of the placement groove 9. A positioning groove 11 is opened on the inner surface of the steel beam connecting sleeve 3. A cover plate 12 is provided inside the placement groove 9. An anchor rod 13 is fixedly installed on the lower surface of the cover plate 12.

[0027] The external shape and size of the rectangular insert 7 are adapted to the internal shape and size of the rectangular sleeve 5. The external shape and size of the first positioning block 4 and the second positioning block 6 are adapted to the internal shape and size of the steel beam connecting sleeve 3, so that the rectangular insert 7 can be inserted into the rectangular sleeve 5 and the first positioning block 4 and the second positioning block 6 can be inserted into the steel beam connecting sleeve 3. After the rectangular insert 7 is inserted into the rectangular sleeve 5, the through hole 8 on the rectangular insert 7 corresponds to and is connected to the through hole 8 on the rectangular sleeve 5.

[0028] It should be noted that there are multiple anchor rods 13. The number of through holes 8, round holes 10 and positioning grooves 11 is equal to the number of anchor rods 13. The anchor rods 13 are adapted to the through holes 8, round holes 10 and positioning grooves 11, so that the anchor rods 13 can pass through the round holes 10 and through holes 8 in sequence and be inserted into the positioning grooves 11.

[0029] The first box-shaped steel beam 1 and the second box-shaped steel beam 2 have the same cross-sectional dimensions, and the cross-sectional dimensions of the first box-shaped steel beam 1 and the second box-shaped steel beam 2 are larger than the internal dimensions of the steel beam connecting sleeve 3.

[0030] It should be noted that the upper surface of the steel beam connecting sleeve 3 has a number of grooves 14 located on both sides of the placement groove 9 and connected to the placement groove 9.
