Description

Technical Field

[0001] The present application relates to the technical field of steel structure building construction, and in particular to a reinforced concrete seamless structure. Background Art

[0002] In the field of engineering design and construction, it is common for steel structures to have long plane dimensions, even up to hundreds of meters. Since steel structures are sensitive to temperature changes, such super-long steel structures will expand when heated and contract when cooled, which will cause temperature stress inside the steel structure, thus posing a safety hazard to the steel structure. At present, the conventional practice is to set expansion joints between beams to solve the problem of cracks in the steel structure caused by thermal expansion and contraction.

[0003] In the related art, although expansion joints can effectively solve the problem of beam cracking, for buildings with special structures, the existence of expansion joints often affects the overall design effect of the building. Utility Model Content

[0004] The present application provides a reinforced concrete seamless structure, the purpose of which is to effectively solve the problem of cracks between steel beams of super-long steel structures without setting expansion joints, and further to effectively ensure the overall architectural design effect of buildings with special structures.

[0005] The present application provides a reinforced concrete jointless structure, which adopts the following technical solution:

[0006] A reinforced concrete seamless structure includes two steel beams symmetrically arranged on the left and right and a telescopic component added between the two steel beams, the telescopic component includes a telescopic plate and two connecting plates, the two connecting plates are integrally formed at the left and right ends of the telescopic plate, the sides of the two connecting plates away from each other are respectively connected to the two steel beams, and the telescopic plate is horizontally arranged between the two connecting plates.

[0007] By adopting the above technical solution, when the two steel beams expand and contract due to the influence of temperature rise and fall, the telescopic components can expand and contract between the two steel beams, and then compensate the internal temperature stress caused by thermal expansion and contraction between the two steel beams through the telescopic components. In this way, the problem of cracking between the steel beams of the super-long steel structure can be effectively solved without setting expansion joints, and the overall architectural design effect of those buildings with special structures can be effectively guaranteed.

[0008] The telescopic plate and the two connecting plates are both made of rubber, which makes the telescopic plate and the two connecting plates themselves have a certain degree of elasticity. When thermal expansion and contraction occur between the two steel beams, the telescopic plate extends and contracts, thereby effectively solving the problem of cracks between the steel beams of the super-long steel structure.

[0009] Preferably, the connecting plate is composed of a first plate body and a second plate body, the first plate body is connected to the steel beam, and the second plate body is connected to the telescopic plate;

[0010] The telescopic plate is in the shape of a corrugated plate as a whole.

[0011] By adopting the above technical solution, the stability of the connection between the telescopic plate and the steel beam is effectively strengthened by utilizing the first plate body and the second plate body; at the same time, the telescopic plate is set to be wavy, which is convenient for the telescopic plate to retract, and at the same time, is beneficial to improve the overall structural strength of the telescopic plate, making the telescopic plate more stable during the retraction process.

[0012] Preferably, both left and right ends of the first plate body are integrally formed with connecting plates in the horizontal direction, and the connecting plates are fastened to the steel beam.

[0013] By adopting the above technical solution, the connection strength between the connecting plate and the steel beam is further strengthened by using the connecting piece, thereby effectively ensuring the stability of the telescopic component installed between the two steel beams.

[0014] Preferably, the connecting plate is fastened to the steel beam by fastening bolts.

[0015] By adopting the above technical solution, the connecting piece is fixed by fastening bolts, which makes it convenient to replace the connecting piece and further facilitate the replacement of the consumable parts.

[0016] Preferably, a reset pad is integrally formed between the two first plates along the horizontal direction, and the reset pad is located below the telescopic plate.

[0017] By adopting the above technical solution, the reset pad itself has a certain elasticity and can be made of rubber material. When the two steel beams expand due to heat, the telescopic plate and the two connecting plates are driven to shrink, and the reset pad shrinks synchronously; when the two steel beams shrink due to cold, the telescopic plate and the two connecting plates are reset while the reset pad installed between the two first plates can assist in the resetting of the telescopic plate, thereby helping to reset the telescopic plate more quickly and efficiently.

[0018] Preferably, the connection piece and the steel beam are connected by sliding.

[0019] By adopting the above technical solution, the sliding connection method makes it easy to connect the connecting plate to the steel beam, further facilitating construction.

[0020] Preferably, a sliding slot is provided on the side wall of the steel beam, and the connecting piece is slidably inserted into the sliding slot.

[0021] By adopting the above technical solution, during installation, the connecting piece can be directly slid into the sliding slot, which is very convenient.

[0022] Preferably, the steel beam is provided with a positioning groove along its length direction, and the connecting piece is provided with a positioning hole, and the positioning groove and the positioning hole are used to position the connecting piece to the steel beam.

[0023] By adopting the above technical solution, after the connecting piece is slid into the sliding slot, the fastening bolt is passed through the positioning slot and tightened into the positioning hole to complete the positioning of the connecting piece.

[0024] In this arrangement, when the installation position of the connecting piece needs to be adjusted, the depth of the connecting piece can be adjusted by sliding it into the sliding slot, and after the adjustment is completed, the fastening bolt is passed through the positioning slot and tightened into the positioning hole. Furthermore, by providing a positioning slot on the steel beam, the installation position of the connecting piece on the steel beam can be adjusted, which is conducive to improving the overall adaptability of the structure.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When the two steel beams expand and contract due to the influence of temperature rise and fall, the telescopic components can expand and contract between the two steel beams, and then compensate for the internal temperature stress caused by thermal expansion and contraction between the two steel beams through the telescopic components. In this way, the problem of cracking between the steel beams of the super-long steel structure can be effectively solved without setting expansion joints, and the overall architectural design effect of those buildings with special structures can be effectively guaranteed.

[0027] The telescopic plate and the two connecting plates are made of rubber, which makes them elastic. When thermal expansion and contraction occur between the two steel beams, the telescopic plate will expand and contract, and the problem of cracks between the steel beams of the super-long steel structure can be effectively solved by the telescopic plate.

[0028] 2. The first plate body and the second plate body are used to effectively strengthen the stability of the connection between the telescopic plate and the steel beam; at the same time, the telescopic plate is set to be wavy, which is convenient for the telescopic plate to retract, and at the same time, it is beneficial to improve the overall structural strength of the telescopic plate, making the telescopic plate more stable during the retraction process;

[0029] 3. After the connecting piece is slid into the sliding slot, pass the fastening bolt through the positioning slot and tighten it into the positioning hole to complete the positioning of the connecting piece.

[0030] In this arrangement, when the installation position of the connecting piece needs to be adjusted, the depth of the connecting piece can be adjusted by sliding it into the sliding slot, and after the adjustment is completed, the fastening bolt is passed through the positioning slot and tightened into the positioning hole. Furthermore, by providing a positioning slot on the steel beam, the installation position of the connecting piece on the steel beam can be adjusted, which is conducive to improving the overall adaptability of the structure.

[0034] The following will further describe the present application in detail with reference to the attached Figure 1 - attached Figure 2 drawings.

[0035] Embodiment 1:

[0036] The embodiment of the present application discloses a seamless structure for reinforced concrete. Referring to Figure 1 , it includes two steel beams 1 arranged symmetrically on the left and right and a telescopic assembly 2 arranged between the two steel beams 1. When the two steel beams 1 expand and contract due to temperature rise and fall, the telescopic assembly 2 can expand and contract between the two steel beams 1, thereby compensating for the internal temperature stress caused by thermal expansion and contraction between the two steel beams 1 through the telescopic assembly 2. Thus, the problem of cracking between the steel beams 1 of the super-long steel structure can be effectively solved without setting expansion joints, and the overall architectural design effect of those buildings with special structures can be effectively guaranteed.

[0037] Specifically, referring to Figure 1 , the telescopic assembly 2 includes a telescopic plate 21 and two connecting plates 22. The two connecting plates 22 are integrally formed at the left and right ends of the telescopic plate 21 respectively. The sides of the two connecting plates 22 away from each other are respectively connected to the two steel beams 1. The telescopic plate 21 is horizontally arranged between the two connecting plates 22, and the telescopic plate 21 and the two connecting plates 22 form a "U" - shaped structure. The telescopic plate 21 and the two connecting plates 22 are both made of rubber material, which makes the telescopic plate 21 and the two connecting plates 22 have certain elasticity themselves. When thermal expansion and contraction occur between the two steel beams 1, the telescopic plate 21 expands and contracts, thereby effectively solving the problem of cracking between the steel beams 1 of the super-long steel structure through the telescopic plate 21.

[0038] Specifically, referring to Figure 1The connecting plate 22 is composed of a first plate body 221 and a second plate body 222. The first plate body 221 is vertically arranged, and the second plate body 222 is horizontally arranged. The first plate body 221 and the second plate body 222 form an inverted "L" structure. The first plate body 221 is connected to the steel beam 1, and the second plate body 222 is connected to the telescopic plate 21. The stability of the connection between the telescopic plate 21 and the steel beam 1 is effectively enhanced by the first plate body 221 and the second plate body 222.

[0039] In this embodiment, the telescopic plate 21 is in the shape of a wave plate as a whole. The wave shape of the telescopic plate 21 facilitates the telescopic plate 21 to retract, and at the same time, it is beneficial to improve the overall structural strength of the telescopic plate 21, so that the telescopic plate 21 is more stable during the retraction process.

[0040] Further, refer to Figure 1 The left and right ends of the first plate 221 are integrally formed with rectangular parallelepiped connecting pieces 3 in the horizontal direction, and the connecting pieces 3 are fastened to the steel beam 1 by fastening bolts. The connecting pieces 3 are used to further strengthen the connection strength between the connecting plate 22 and the steel beam 1, thereby effectively ensuring the stability of the telescopic assembly 2 installed between the two steel beams 1.

[0041] At the same time, the connecting piece 3 is fixed by tightening the bolts, which makes it easy to replace the connecting piece 3 and further replace the consumable parts.

[0042] The implementation principle of a reinforced concrete jointless structure in the embodiment of the present application is as follows:

[0043] When the two steel beams 1 expand and contract due to the influence of temperature rise and fall, the telescopic assembly 2 can expand and contract between the two steel beams 1, and then compensate the internal temperature stress caused by the thermal expansion and contraction between the two steel beams 1 through the telescopic assembly 2. In this way, the problem of cracks between the steel beams 1 of the super-long steel structure can be effectively solved without setting expansion joints, and the overall architectural design effect of those buildings with special structures can be effectively guaranteed.

[0044] Embodiment 2:

[0045] The difference between the embodiment of the present application and embodiment 1 is that:

[0046] Reference Figure 1A reset pad 4 is integrally formed between the two first plates 221 along the horizontal direction, and the reset pad 4 is located directly below the telescopic plate 21. The reset pad 4 itself has a certain elasticity, and can be made of rubber. When the two steel beams 1 expand due to heat, the telescopic plate 21 and the two connecting plates 22 are driven to contract, and the reset pad 4 contracts synchronously; when the two steel beams 1 contract due to cold, the telescopic plate 21 and the two connecting plates 22 are reset, and the reset pad 4 installed between the two first plates 221 can assist the resetting of the telescopic plate 21, thereby helping the resetting of the telescopic plate 21 to be faster and more efficient.

[0047] Embodiment 3:

[0048] The difference between the embodiment of the present application and embodiment 1 and embodiment 2 is that:

[0049] The connection piece 3 and the steel beam 1 are connected by a sliding connection method, which makes it easy to connect the connection piece 3 and the steel beam 1, and further facilitates construction.

[0050] Specifically, refer to Figure 1 and Figure 2 The side wall of the steel beam 1 is provided with a sliding slot 5 in the horizontal direction, and the sliding slot 5 is adapted to the connecting piece 3. Specifically, during installation, the connecting piece 3 can be directly slid into the sliding slot 5, which is very convenient.

[0051] Further, refer to Figure 1 and Figure 2 The steel beam 1 is also provided with a long strip-shaped positioning groove 6 along its length direction, and the connecting piece 3 is provided with a positioning hole 7. When the connecting piece 3 is slid into the sliding slot 5, the fastening bolt is passed through the positioning groove 6 and tightened into the positioning hole 7 to complete the positioning of the connecting piece 3.

[0052] In this arrangement, when the installation position of the connecting piece 3 needs to be adjusted, the depth of the connecting piece 3 in the sliding slot 5 can be adjusted, and after the adjustment is completed, the fastening bolt is passed through the positioning slot 6 and tightened into the positioning hole 7. Furthermore, by providing the positioning slot 6 on the steel beam 1, the installation position of the connecting piece 3 on the steel beam 1 can be adjusted, which is conducive to improving the adaptability of the overall structure.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
