Description

Technical Field

[0001] The utility model relates to the technical field of temporary beam supports, in particular to a temporary beam support structure which is convenient for assembly and disassembly. Background Art

[0002] The construction of underpass railway overpasses usually adopts the jacking method. During the jacking period, the railway needs to operate normally. To ensure the safe operation of the railway, temporary beams must be erected before the jacking construction to ensure the safe operation of the railway. The temporary beams are erected on the temporary beam piers.

[0018] Optionally, a second rubber pad is provided at the connection between the steel pier and the crossbeam, and the second rubber pad is connected to the bottom of the steel pier.

[0019] By adopting the above technical solution, the friction force when the steel pier is connected with the beam is increased, making the steel pier more stable during installation.

[0020] Optionally, locking bolts are screwed onto the upper ends of both sides of the steel pier, and the two groups of locking bolts extend into the interior of the reserved column on one side close to the center of the steel pier.

[0021] By adopting the above technical solution, the reserved column is locked and fixed by the locking bolt, thereby making the connection between the reserved column and the reserved groove more secure.

[0022] In summary, the present invention has at least one of the following beneficial effects:

[0023] Through the mutual coordination of pile foundation, crossbeam, steel pier, temporary beam body, reserved column and reserved groove, the reserved column at the bottom of the temporary beam body is inserted into the corresponding reserved groove, thereby facilitating the rapid disassembly and assembly between the temporary beam body and the steel pier, solving the problem that the traditional temporary beam pier is a reinforced concrete structure, which is bulky and has a long construction period, and thus the temporary beam pier cannot be recycled.

[0024] Through the mutual cooperation of the positioning blocks and the positioning grooves, the steel piers can be positioned to ensure that the central axes of multiple steel piers coincide with each other, and to avoid vibration when vehicles pass by, which may cause the steel piers to shift. At the same time, the middle part of the steel pier is set to a hollow structure to reduce the production cost of the steel pier, making the steel pier have the advantages of lightweight and energy saving.

[0031] The following is combined with Figure 1-4 The utility model is described in further detail.

[0032] Please refer to the attached figure in the instruction manual Figure 1 and Figure 3The utility model provides an embodiment: a convenient beam support structure that is easy to assemble and disassemble, comprising a crossbeam 2, both ends of the bottom of the crossbeam 2 are fixedly connected to a pile foundation 1, and both ends of the top of the crossbeam 2 are fixedly installed with a limit plate 3, and a steel pier 4 is placed between the two sets of limit plates 3, and the middle part of the steel pier 4 is a hollow structure. This reduces the production cost of the steel pier 4, making the steel pier 4 have the advantages of being lightweight and energy-saving. The inner side wall of the steel pier 4 is provided with a plurality of reinforcing ribs 15, and both ends of the plurality of reinforcing ribs 15 extend out of the steel pier 4. This further improves the strength of the steel pier 4, making it less likely for the steel pier 4 to bend.

[0033] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 Several positioning blocks 11 are fixedly attached to the front and rear ends of the bottom of the steel buttress 4. The top of the crossbeam 2 is provided with positioning slots 12 that engage with the positioning blocks 11. Inserting the positioning blocks 11 into the corresponding positioning slots 12 allows for preliminary positioning of the steel buttress 4. Connecting lugs 13 are attached to the tops of the front and rear ends of the steel buttress 4. Both sets of connecting lugs 13 have through-holes in their centers, facilitating the lifting of the steel buttress 4 through the connecting lugs 13.

[0034] Please refer to the attached figure in the instruction manual Figure 1 ,and Figure 2 and Figure 4 A second rubber pad 10 is provided at the connection between the steel pier 4 and the crossbeam 2, and the second rubber pad 10 is connected to the bottom of the steel pier 4. This increases the friction force when the steel pier 4 is connected to the crossbeam 2, making the steel pier 4 more stable during installation. Both ends of the top of the steel pier 4 are equipped with a temporary beam body 5, and the bottoms of the two sets of temporary beam bodies 5 are connected to the first rubber pad 7. This increases the friction force when the temporary beam body 5 is connected to the steel pier 4, and at the same time, the vibration generated when the vehicle passes through the temporary beam body 5 can also absorb part of the energy through the first rubber pad 7.

[0035] Please refer to the attached figure in the instruction manual Figure 1 、 Figure 3 and Figure 4 The bottoms of the two sets of temporary beam bodies 5 are connected to reserved columns 6. The tops of the steel piers 4 are provided with reserved slots 8 that are plugged into the reserved columns 6. The upper ends of both sides of the steel piers 4 are screwed with locking bolts 9. The two sets of locking bolts 9 extend into the interior of the reserved columns 6 on the side close to the center of the steel pier 4. The reserved columns 6 are locked and fixed by the locking bolts 9, making the connection between the reserved columns 6 and the reserved slots 8 more secure.

[0036] Working principle: When in use, the prefabricated steel pier 4 is transported to the construction site, and the steel pier 4 is hoisted through the connecting ear 13. The steel pier 4 can be preliminarily positioned through the mutual cooperation of the positioning block 11 and the positioning groove 12. The steel pier 4 is hoisted to the top of the beam 2. At this time, the steel pier 4 is located between the two sets of limiting plates 3, and the steel pier 4 can be further limited. The middle part of the steel pier 4 is set to a hollow structure, thereby reducing the production cost of the steel pier 4, so that the steel pier 4 has the advantages of lightweight and energy saving.

[0037] The reserved column 6 at the bottom of the temporary beam body 5 is inserted into the corresponding reserved groove 8, so that the temporary beam body 5 can be quickly erected on the top of the steel pier 4. Then the operator screws the locking bolt 9 into the reserved column 6 to fix the reserved column 6, making the connection between the reserved column 6 and the reserved groove 8 more firm, thereby ensuring that the connection between the temporary beam body 5 and the steel pier 4 is more stable, and then the temporary beam body 5 can be separated from the steel pier 4 in the later stage, so that the steel pier 4 can be recycled; after the temporary beam body 5 and the steel pier 4 are erected, the construction and jacking of the box culvert 14 will not affect the normal operation of the railway.

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
