Example

The embodiment of the present application provides a gantry crane end well track beam 100 (hereinafter referred to as "track beam 100"), as shown in FIG. 1 , FIG. 2 and FIG. 3 , the track beam 100 is arranged on the end well track 20 and base 30.

Referring to FIG. 2 , FIG. 3 , and FIG. 4 , the above-mentioned track beam 100 includes a first layer 110 and a second layer 120 , and the first layer 110 and the second layer 120 are fixedly connected as a whole.

The first layer 110 is a format structure formed by splicing a plurality of I-beams along its width direction. Referring to Figure 3, the flange edges of adjacent I-beams are connected and fixed, and the fixing method can be welding, sticking. Knots or anchors, etc., in this embodiment, the butt weld is fully welded, that is, the butt welding is fully welded along the length direction of the I-beam. Optionally, in the case of meeting the force requirements, it can also be connected by spot welding.

Optionally, in the case of meeting the force requirements, it can also be connected by spot welding.

The first layer 110 of the track beam 100 mainly bears the pressure from the upper part, and uses a plurality of I-beams to form a grid structure by splicing along the width direction. Reduce the load of the lower foundation 30; in addition, the width of the first layer 110 can be adjusted according to the width of the end well foundation 30. If the end well foundation 30 is wider, a few more I-beams are spliced, and the foundation 30 is narrower to reduce labor. The steel beam has the characteristics of convenient installation and strong applicability. When the foundation 30 is wide, the stress area can be increased as much as possible to prevent the local stress of the foundation 30 from being too large. The second layer 120 directly bears the pressure of the rail, and is laid across the surface of the I-beam by using a plurality of H-beams. The H-beam transmits the force from the rail to the first layer 110 of the rail beam 100, increasing the first The stress area of the layer 110 prevents the local stress of the first layer 110 from being too large, and the H-beam plays the role of tying multiple I-beams. Nodes are not prone to damage.

The above H-beams are arranged at intervals, and adjacent H-beams are not connected. The main function of H-beam is to undertake rails and tie I-beams. H-beams arranged at intervals can reduce their own weight and save materials while meeting the requirements.

Optionally, the length of the H-shaped steel is greater than or equal to the width of the first layer 110 , so that the first layer 110 can bear the pressure from the upper part over the entire width, and the damage of the first layer 110 due to excessive local pressure is reduced.

The connection between the rail beam 100 and the end well rail 20 may be fixed connection by welding, anchoring, etc. Optionally, a rail pressure plate 300 is provided on the second layer 120 of the rail beam 100, and the rail pressure plate 300 connects the end well rail 20. Pressed on the second layer 120 , when the end well track 20 has a tendency to move away from the second layer 120 , the track pressing plate 300 provides a downward pressure force to reduce the connection between the end well track 20 and the second layer 120 . The relative force prevents the installation site of the end well track 20 from being damaged and disengaged.

The above-mentioned rail pressing plate 300 can be fixed on the second layer 120 by welding, anchoring or the like. In this embodiment, the rail pressing plate 300 is connected with the H-shaped steel of the second layer 120 by means of an opposite screw. When manufacturing the rail beam 100 , a threaded hole is reserved on the H-shaped steel, and the threaded hole is arranged on the flange of the H-shaped steel; when the rail pressing plate 300 is produced, a threaded hole is reserved on the rail pressing plate 300 . When installing the end well track 20, the threaded holes of the track pressing plate 300 correspond to the threaded holes of the H-shaped steel, and the opposite threaded screws are used to pass through the two corresponding threaded holes, and are fixed with nuts, so that the track pressing plate 300 is connected to the second threaded hole.

The inventor found that the heights of the top surface of the foundation 30 to the ground may be different in the end wells at different positions. In order to make the gantry crane end well track 20 and the front and rear road tracks connect on the same level, it is necessary to make the top surface of the foundation 30 different from the ground. The height of the composite beam meets different height requirements. If different specifications of I-beam or H-beam are used to meet the height requirements, it will reduce the speed of mass production by workers. Since the height of the foundation 30 is generally set according to the design requirements, its height is fixed and cannot be adjusted at will, otherwise it may have an impact on the later structural construction.

Therefore, optionally, the inventor provides the above-mentioned concrete leveling layer 200 for adjusting the height and levelness of the track beam 100 .

The rail beam 100 spans over the end well of the gantry crane, and the two ends of the rail beam 100 are respectively erected on the foundation 30 .

The concrete leveling layer 200 is a temporary structure, and can be removed after the end well track 20 is removed, which has little impact on the structure of the foundation 30 and the structure of the upper body in the later stage, and does not affect the later construction.

Optionally, a bearing steel plate 210 is pre-embedded on the concrete leveling layer 200 , and the bearing steel plate 210 is connected to the first layer 110 of the track beam 100 .

The concrete leveling layer 200 can be poured after the foundation 30 is poured. When the concrete leveling layer 200 is poured, a bearing steel plate 210 is pre-embedded on the upper surface of the concrete leveling layer 200 to facilitate the connection of the rail beam 100 . After the concrete leveling layer 200 is formed and reaches the required concrete strength value, the rail beam 100 is hoisted, and both ends of the rail beam 100 are connected to the pre-embedded bearing steel plates 210. Optionally, the first layer 110 of the rail beam 100 It is fixed on the pressure-bearing steel plate 210 by means of anchoring, welding or the like.

Since the concrete leveling layer 200 is only used for height and leveling, its strength requirements are lower than those of the existing cast-in-place rail beams, and the volume is relatively small, so it takes less time to wait for it to form. The impact of the construction period is small. The bearing steel plate 210 also increases the bearing capacity of the concrete leveling layer 200, and the upper pressure is transmitted to the concrete leveling layer 200 through the bearing steel plate 210, and the concrete leveling layer 200 is uniformly stressed and is not easily damaged due to excessive local stress.

The H-beams are arranged along the length direction of the I-beams of the first layer 110 at the interval of 0.5m. The length of a single H-beam is slightly larger than the width of the first layer 110, that is, the two ends of each H-beam The two sides of layer 110 are shown in FIG. 3 . The H-beam is fixed on the I-beam of the first layer 110 by means of fillet welding. During welding, the H-beam is fully welded along the length of the H-beam, so that the H-beam and each I-beam are fixedly connected.

After the first layer 110 and the second layer 120 of the track beam 100 are fabricated, they can be hoisted on site. The track beam 100 is mechanically hoisted to the position of the end well by a tower crane, crane, etc., and then lowered slowly, and then the track beam 100 is fixed.
