Abstract
Description
Technical Field
[0001] The present application relates to the field of building construction technology, and in particular to a steel box girder pier-beam consolidation structure. Background Art
[0002] During bridge construction, temporary consolidation is usually performed on steel box girders and pier beams to ensure that the steel box girders can withstand various loads during construction and maintain structural stability. Once the construction is completed and passed the acceptance inspection, the temporary consolidation will be released to restore the structure to its designed state. In bridge engineering, the use of sand barrels for temporary consolidation is a common construction method.
[0003] In existing devices, sand is usually filled into a sand barrel to support the steel box girder. When the construction is completed, the sand is removed from the sand unloading hole at the bottom of the sand barrel to lower the support height of the sand barrel, and then the temporary consolidation structure is dismantled.
[0004] However, due to the long construction period of bridge buildings, the sand in the sand barrel is easily damp and agglomerated, and the diameter of the sand unloading hole of the sand barrel is small, making it difficult to remove the sand, which makes disassembly more difficult during actual use. Construction workers often cut the sand barrel directly to shorten the disassembly time.
[0005] In view of this, the purpose of the present invention is to provide a steel box girder pier-beam consolidation structure that is easy to disassemble. Utility Model Content
[0006] The content of this application is used to briefly introduce concepts that will be described in detail in the detailed description section below. The content of this application is not intended to identify key features or essential features of the technical solution for which protection is sought, nor is it intended to limit the scope of the technical solution for which protection is sought.
[0007] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a steel box girder pier-beam consolidation structure, including a sand barrel and a sand cover. The side wall portion of the sand barrel is penetrated to form a sand unloading port. A first convex ring and a second convex ring are fixedly arranged on both sides of the sand unloading port along the height direction of the sand barrel. A cover plate is arranged between the first convex ring and the second convex ring. The cover plate covers the sand unloading port. The surface portion of the cover plate protrudes to form an anti-unloading block. The anti-unloading block is arranged in the sand unloading port; rods are inserted into the first convex ring, the cover plate, and the second convex ring in sequence along the vertical direction, and at least two rods are arranged.
[0008] During the working process, after the sand is loaded into the sand barrel, the sand cover is placed in the sand barrel, the steel box girder is hoisted on the sand cover, and then the sand cover is fixedly connected to the steel box girder, and the sand barrel is fixedly connected to the pier beam to realize the temporary consolidation of the steel box girder and the pier beam; since a sand unloading port and a cover plate are provided, the cover plate can block the sand unloading port in the supporting state to prevent sand from leaking, and the cover plate can be removed to take out the sand from the sand unloading port during disassembly; since an insertion rod and a first convex ring and a second convex ring are provided, the first convex ring and the second convex ring can fix the position of the cover plate in the vertical direction, and the insertion rod can fix the position of the cover plate in the horizontal direction; when the consolidation structure needs to be disassembled, the insertion rod is pulled out to remove the cover plate, and then the sand is removed from the sand unloading port, the height of the sand cover is lowered, and the disassembly is completed.
[0009] Furthermore, an anti-falling screw head is welded to the top of the insertion rod, and a thread line is formed on the bottom of the insertion rod so that the insertion rod can be fixed by a nut.
[0010] Furthermore, a rubber pad is bonded to the cover plate, and the surface of the rubber pad is in close contact with the side wall of the sand barrel.
[0011] Furthermore, a plurality of sand discharge ports and cover plates are arranged in a circular array along the axial direction of the sand barrel.
[0012] Furthermore, the sand discharge port is arranged at a distance of 50mm-100mm from the bottom of the sand barrel.
[0013] Furthermore, the inner wall portion of the sand barrel is concave to form a limiting groove, and the side wall portion of the sand cover is protruding to form a limiting plate corresponding to the limiting groove, and the limiting plate can be inserted into the limiting groove.
[0014] Furthermore, a bottom plate is welded to the bottom of the sand barrel, and the bottom plate is fixed on the pier beam by bolts;
[0015] The top plate is welded on the top of the sand barrel and fixed to the steel box girder by bolts.
[0016] Furthermore, reinforcing ribs are welded between the bottom plate and the sand barrel.
[0017] The beneficial effects of this application are:
[0018] 1. The opening area of the sand discharge port is large, which is convenient for manually removing the sand in the sand barrel, thereby realizing the disassembly of the consolidated structure; the sand discharge port is sealed by setting a cover plate to prevent sand leakage, and the position of the cover plate is fixed by setting the first convex ring, the second convex ring, and the insertion rod to prevent the cover plate from shifting after being squeezed by the sand.
[0019] 2. The setting of the rubber pad can seal the sand unloading port to prevent sand from leaking from the gap between the sand barrel and the cover plate.
[0020] 3. By setting the sand discharge port 50mm-100mm away from the bottom of the sand barrel, the sand near the top of the sand barrel can be directly taken out, making the sand cover easier to drop. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0034] A steel box girder pier-beam consolidation structure includes a sand tube 3 and a sand cover 4. A bottom plate 5 is welded to the bottom of the sand tube 3, and reinforcing ribs 6 are welded between the bottom plate 5 and the side wall of the sand tube 3. A top plate 7 is welded to the top of the sand cover 4. The sand cover 4 can extend into the sand tube 3 and is cylindrical. The side wall of the sand cover 4 is arranged in contact with the inner wall of the sand tube 3.
[0035] During use, first fix the bottom plate 5 to the pier beam 2 with bolts, inject sand into the sand tube 3, and after the sand is injected to a suitable height, cover the sand cover 4 on the sand tube 3; use lifting equipment to lift the steel box beam 1 on the sand cover 4, and then use bolts to fix the sand cover 4 to the steel box beam 1, thereby realizing temporary consolidation of the steel box beam 1 and the pier beam 2.
[0036] The temporary consolidation structure only serves to temporarily support and maintain the stability of the steel box girder 1. After the bridge construction is completed, the temporary consolidation structure needs to be dismantled to restore the structure to its original design state. Therefore, the steel box girder pier consolidation structure also includes a structure that facilitates the later disassembly of the sand barrel 3 and sand cover 4.
[0037] Specifically, the side wall portion of the sand barrel 3 is penetrated to form a sand unloading port 8, and a first convex ring 9 and a second convex ring 10 are fixedly provided on both sides of the sand unloading port 8 along the height direction of the sand barrel 3. The first convex ring 9 and the second convex ring 10 are connected to the sand barrel 3 by welding. A cover plate 11 is provided between the first convex ring 9 and the second convex ring 10. The top surface of the cover plate 11 is in close contact with the bottom surface of the first convex ring 9, and the bottom surface of the cover plate 11 is in close contact with the top surface of the second convex ring 10. The cover plate 11 can cover the sand unloading port 8. The surface portion of the cover plate 11 protrudes to form an anti-unloading block 12. The anti-unloading block 12 is provided in the sand unloading port 8, and the side wall of the anti-unloading block 12 is in close contact with the side wall of the sand unloading port 8; the first convex ring 9, the cover plate 11, and the second convex ring 10 are sequentially inserted into the same insertion rod 13 in the vertical direction. At least two insertion rods 13 are provided. The joint action of the two insertion rods 13 can limit the cover plate 11 in the horizontal direction;
[0038] The sand discharge port 8 provided on the sand barrel 3 has a relatively large opening. When disassembly is required, the user only needs to remove the insertion rod 13 and pull out the cover plate 11 to take out the sand through the sand discharge port 8 .
[0039] An inserting plate 14 is welded to the first protruding ring 9, the cover plate 11, and the second protruding ring 10. An inserting hole 15 is formed through the surface portion of the inserting plate 14. The inserting rod 13 is inserted into the inserting hole 15 on the first protruding ring 9, the cover plate 11, and the second protruding ring 10. In order to fix the inserting rod 13, an anti-falling screw head 16 is welded on the top of the inserting rod 13. A threaded line 17 is formed on the bottom of the inserting rod 13 so that the inserting rod 13 can be fixed by a nut 18;
[0040] Furthermore, in order to seal the sand tube 3 , a rubber pad 19 is bonded to the cover plate 11 . The surface of the rubber pad 19 is in close contact with the side wall of the sand tube 3 . The rubber pad 19 can prevent sand from leaking from the gap between the sand tube 3 and the cover plate 11 .
[0041] In order to further facilitate the construction workers to remove sand, multiple sand unloading ports 8 and cover plates 11 are arranged in a circular array along the axial direction of the sand barrel 3. In this embodiment, two sand unloading ports 8 are arranged. The arrangement of the two sand unloading ports 8 enables the workers to remove sand from different directions of the sand barrel 3, avoiding the problem of difficulty in removing sand from a position far away from the sand unloading port 8 due to the adhesion of the sand after it becomes wet.
[0042] In this embodiment, the sand discharge port 8 is set at 80 mm from the bottom of the sand barrel 3, and the sand near the upper part of the sand barrel 3 is directly taken out, which is more conducive to the landing of the sand cover 4.
[0043] In order to prevent the sand cover 4 from rotating in the circumferential direction, the inner wall portion of the sand barrel 3 is concave to form a limit groove 20, and the side wall portion of the sand cover 4 protrudes to form a limit plate 21 corresponding to the limit groove 20. The limit plate 21 can be inserted into the limit groove 20. Four limit grooves 20 and limit rods are arranged in a circular array along the axial direction of the sand barrel 3.
[0044] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
