Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated beam storage, in particular to a detachable double-layer beam storage pedestal. Background Art

[0002] Prefabricated I-beams are mostly stored in single or double layers. Since single-layer storage requires a lot of space, most of them are stored in double layers. The existing double-layer storage usually places wooden blocks on the lower prefabricated I-beams, and then places the upper prefabricated I-beams on the wooden blocks. This placement method is not conducive to the accuracy control of the lifting and placement of the upper prefabricated I-beams, and is prone to tilting. In addition, since the entire gravity of the upper prefabricated I-beams acts on the wooden blocks on both sides, it will generate large local stress on the ends of the lower prefabricated I-beams, which will easily cause the concrete at the ends of the lower prefabricated I-beams to crack when stacked for a long time.

[0003] The patent with announcement number CN 217754927 U provides a double-layer storage rack for prefabricated box girders, including concrete pedestals on the left and right sides of the beam storage pedestal, the concrete pedestals are fixed upward to a support frame, the support frame includes two vertical supports in front and back, the middle parts of the vertical supports are connected together through upper pads; a laser is installed at the bottom of the vertical support, a corner hole A is provided at the top of the vertical support, and a corner hole B communicating with the corner hole A is provided at the upper part of the vertical support. The double-layer beam storage rack can disperse the pressure of the upper prefabricated box girders and reduce the damage to the lower prefabricated box girders; the upper pads and the lower pads are aligned in the same straight line through laser calibration.

[0004] However, the support frame is fixed on a concrete pedestal, and the second-layer pads are fixedly connected to the support frame, which is not conducive to disassembly and turnover of equipment. Utility Model Content

At the same time, the concrete pedestal and the support frame are detachable structures to facilitate the turnover of equipment.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0015] Furthermore, bolt holes are formed at both ends of the second-layer sleeper, and the bolt holes are correspondingly arranged with the through holes on the support frame.

[0016] Furthermore, the bottom surface of the second-layer sleeper is in contact with both ends of the top surface of the first-layer I-beam, and the top surface of the second-layer sleeper is in contact with both ends of the bottom surface of the second-layer I-beam.

[0017] Furthermore, laser calibrators are arranged at both ends of the upper surface of the second-layer sleeper. The laser calibrators emit vertically upward laser calibration lines, and the laser calibration lines are aligned with the edges of the second-layer I-beam.

Above the concrete pedestal 1, a first-layer I-beam 3 is provided. Between the first-layer I-beam 3 and the concrete pedestal 1, a plurality of first-layer cushion woods 2 are provided. In this embodiment, two first-layer cushion woods 2 are provided, and the two first-layer cushion woods 2 are respectively located at both ends of the bottom surface of the first-layer I-beam 3. By providing the first-layer cushion woods 2 between the concrete pedestal 1 and the first-layer I-beam 3, the first-layer cushion woods 2 are thus supported.

[0027] Support devices are provided on both sides of the concrete pedestal 1. The support devices include support frames 7 and diagonal braces. The two support frames 7 are arranged in parallel. The support frames 7 adopt a frame structure. At both ends of the bottom of the support frames 7, heavy-duty casters 9 are provided. The support frames 7 can be moved by using the heavy-duty casters 9. The heavy-duty casters 9 adopt lockable heavy-duty casters. When the support frames 7 move to the set position, the heavy-duty casters 9 can be locked, thereby fixing the position of the support frames 7. The bearing capacity of a single heavy-duty caster 9 is 1 - 1.2 tons, thus meeting the bearing capacity requirements.

[0028] On both sides of the two support frames 7, there are fixed inclined braces. The inclined brace includes two inclined brace rods 10 arranged in parallel. The inclined brace rods 10 are telescopic structures. The two inclined brace rods 10 are connected by a plurality of connecting rods 12. The plurality of connecting rods 12 are arranged in parallel. The inclined brace rod 10 includes a first telescopic rod and a second telescopic rod. The first telescopic rod is sleeved outside the second telescopic rod. The plurality of connecting rods 12 are all fixed on the first telescopic rod. A first through hole is opened at the bottom end of the first telescopic rod. A plurality of second through holes are opened on the outer surface of the second telescopic rod. The plurality of second through holes are evenly arranged along the length direction of the second telescopic rod. Adjust the position of the second telescopic rod in the first telescopic rod, make different second through holes correspond to the first through hole, and sequentially pass bolts through the first through hole and the second through hole, and lock them with nuts to realize the length adjustment of the inclined brace rod 10.

[0029] The top end of the inclined brace rod 10 is hinged to the support frame 7, so that the inclined brace rod 10 can rotate around the hinge point, so that the length and angle of the inclined brace rod 10 can be adjusted according to different on-site environments, so as to adjust the extension distance of the inclined brace rod 10 to meet the requirements of different use environments. The bottom end of the inclined brace rod 10 is fixedly connected with a caster 11. The caster 11 is a lockable caster, so as to cooperate with the support frame 7 to facilitate movement and support.

[0030] During use, the two support frames 7 are respectively pushed to both sides of the concrete pedestal 1. The distance between the two support frames 7 is greater than the width of the first-layer I-beam 3. A second-layer I-beam 13 is placed above the first-layer I-beam 3. A plurality of second-layer cushion woods 4 are arranged between the first-layer I-beam 3 and the second-layer I-beam 13. The length of the second-layer cushion wood 4 is greater than the width of the first-layer I-beam 3. Bolt holes 8 are opened at both ends of the second-layer cushion wood 4. The bolt holes 8 are correspondingly arranged with the through holes on the support frame 7. Both ends of the second-layer cushion wood 4 are fixedly connected with the two support frames 7 respectively through fixing bolts 14. In this embodiment, there are two second-layer cushion woods 4. The two second-layer cushion woods 4 are respectively located on both sides of the two support frames 7, and the bottom surface of the second-layer cushion wood 4 is in contact with both ends of the top surface of the first-layer I-beam 3, and the top surface of the second-layer cushion wood 4 is in contact with both ends of the bottom surface of the second-layer I-beam 13, so as to support the second-layer I-beam 13 by using the second-layer cushion wood 4. By fixedly connecting both ends of the second-layer cushion wood 4 with the two support frames 7 respectively, the support frame 7 is used to share the pressure of the cushion wood and the lower beam.

[0031] Laser calibrators 5 are arranged at both ends of the upper surface of the second-layer cushion wood 4. The laser calibrators 5 can emit vertically upward laser calibration lines 6. The laser calibration lines 6 can be aligned with the edges of the second-layer I-beam 13, so as to play a guiding role when placing the second-layer I-beam 13 and ensure the precise hoisting of the second-layer I-beam 13.

[0032] Working principle

[0033] During use, first place a layer of sleeper blocks at both ends of the concrete pedestal, and hoist and place a layer of I-beams on the layer of sleeper blocks. After the stacking of the layer of I-beams is completed, first place the second-layer sleeper blocks slightly longer than the I-beams at both ends of the top surface of the layer of I-beams, adjust the second-layer sleeper blocks so that the extension distances at both ends are equal. There are bolt holes at both ends of the second-layer sleeper blocks. Push the support device close to the end of the second-layer sleeper block to align the bolt holes at the end of the second-layer sleeper block with the through holes on the support frame, and connect and fix them with bolts, so as to help the sleeper blocks and the lower beam share the pressure;

[0034] After the connection is completed, lock the heavy-duty casters at the bottom of the support frame to prevent the support frame from moving. The diagonal brace is connected to the support frame so that the diagonal brace can bear part of the pressure. According to different distances between the beam storage pedestals, the angle and length of the diagonal brace rod can be adjusted, so as to adjust the extension distance of the diagonal brace rod. After the adjustment is completed, lock the casters;

[0035] Place laser calibrators at both ends of the second-layer sleeper blocks, and ensure that the distance between the two laser calibrators is the same as the beam width. Hoist the second-layer I-beams, and use the laser calibration lines emitted by the laser calibrators to guide the second-layer I-beams, and slowly hoist and place the second-layer I-beams on the second-layer sleeper blocks to complete the stacking of the second-layer I-beams.

[0036] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
