For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Combine the following Figure 1-Figure 4 , through specific embodiments and application scenarios, a support mechanism applied to concrete buildings provided by an embodiment of the utility model is described in detail.

[0028] like Figure 1As shown, the utility model provides a supporting mechanism for concrete buildings, including: a concrete supporting column 1, a steel cylinder 2, an anchor 3, a steel corbel 4 and a sliding support 5. The steel cylinder 2 is fixedly sleeved on the concrete supporting column 1 through the anchor 3, the steel corbel 4 is welded to the steel cylinder 2, and the sliding support 5 is arranged on the steel corbel 4 for being connected to the steel beam 101 of the steel corridor 100.

[0029] It is understandable that the steel corridor 100 is set between the existing concrete building and the new building to improve the multifunctional usability and convenience of the entire building, and facilitate people to quickly pass between the existing concrete building and the new building. One end of the steel corridor 100 is connected to the existing concrete building 200, and the other end is connected to the new building. The support mechanism for concrete buildings provided by the utility model is particularly suitable for being set at the connection between the existing concrete building 200 and the steel corridor 100.

[0030] Specifically, Figure 1 As shown, the concrete support column 1 can be the original structural column of the existing concrete building 200. The concrete support column 1 can be a rectangular column, a round column or a special-shaped column. Correspondingly, the size and shape of the steel cylinder 2 are adapted to the concrete support column 1. The steel cylinder 2 is sleeved on the concrete support column 1 according to the designed elevation, and the steel cylinder 2 is anchored to the concrete support column 1 by the anchor 3.

[0031] Furthermore, if Figure 1 As shown, the steel cylinder 2 is anchored to the concrete support column 1, and the steel corbel 4 is welded to the steel cylinder 2, thereby realizing a fixed connection between the steel corbel 4 and the concrete support column 1. The steel corbel 4 is located at the lower side of the steel beam 101. The sliding bearing 5 is respectively connected to the steel beam 101 and the steel corbel 4 to transfer the load of the steel beam 101 to the steel corbel 4, and the steel corbel 4 transfers the load to the steel cylinder 2. The steel cylinder 2 is anchored to the concrete support column 1 and is formed as a whole with the concrete support column 1, thereby transferring the load of the steel beam 101 to the ground through the concrete support column 1.

[0032] The utility model provides a supporting mechanism applied to concrete buildings, wherein a steel cylinder 2 is fixedly sleeved on a concrete supporting column 1 through an anchor 3, a steel corbel 4 is welded to the steel cylinder 2, and the steel corbel 4 can be fixed to the concrete supporting column 1 through the steel cylinder 2 and the anchor 3; a sliding support 5 is arranged on the steel corbel 4, and is used to be connected with a steel beam 101 of a steel corridor 100, so as to transfer the load of the steel beam 101 to the steel corbel 4, and the steel corbel 4 transfers the load to the concrete supporting column 1 through the steel cylinder 2, thereby reducing the damage degree of the concrete supporting column 1 to the greatest extent, and the construction steps of the entire supporting mechanism are simple, the construction period is short, and the construction cost is reduced.

[0033] In some embodiments, Figure 2 and Figure 3As shown, the anchor 3 is an anchor bolt. There are multiple anchor bolts. The concrete support column 1 is provided with multiple positioning holes in the circumference. The steel cylinder 2 is provided with multiple mounting holes, and the multiple mounting holes are arranged at intervals along the circumference of the steel cylinder 2. The screw rods of the multiple anchor bolts are correspondingly inserted into the multiple mounting holes and anchored into the multiple positioning holes. The nut of the anchor bolt is sleeved on the screw rod, and is used to tighten the steel cylinder 2 to the concrete support column 1.

[0034] It is understandable that the concrete support column 1 is first connected to the wall of the steel cylinder 2 and roughened; then the positioning holes are laid out according to the design drawings and then holes are drilled on the concrete support column 1. The positioning holes need to avoid the longitudinal reinforcement of the concrete support column 1 to prevent the force system of the concrete support column 1 from being damaged during the construction process. The positioning holes need to have sufficient depth to ensure that the anchor depth of the anchor bolt meets the design requirements.

[0035] The multiple installation holes correspond to the multiple positioning holes one by one. During construction, the screw of the first anchor bolt is first inserted into the first installation hole, and then the screw is anchored into the positioning hole; when the anchoring depth of the screw bolt meets the design requirements, the nut is tightened, and the steel cylinder 2 is tightened to the concrete support column 1 through the nut, so that the inner wall of the steel cylinder 2 is tightly against the outer wall of the concrete support column 1. Repeat the above construction steps in sequence to complete the anchoring process of all anchor bolts.

[0036] In some embodiments, Figure 3 As shown, the steel cylinder 2 is rectangular and comprises a first steel plate 21 , a second steel plate 22 , a third steel plate 23 and a fourth steel plate 24 which are fixedly connected in sequence, and a steel bracket 4 is welded to the first steel plate 21 .

[0037] The second steel plate 22 , the third steel plate 23 and the fourth steel plate 24 have the same thickness, and the thickness of the first steel plate 21 is greater than that of the second steel plate 22 .

[0038] Specifically, in this embodiment, the concrete support column 1 is a rectangular column. Figure 3 As shown, the steel cylinder 2 is a rectangular cylinder. The first steel plate 21, the second steel plate 22, the third steel plate 23 and the fourth steel plate 24 are welded together in sequence along the circumference of the steel cylinder 2 to form the steel cylinder 2, so as to enhance the integrity of the steel cylinder 2.

[0039] The width of each steel plate may be different. The width of each steel plate should be consistent with the width of the side of the corresponding concrete column connected thereto, so that the inner wall of the steel cylinder 2 and the outer wall of the concrete support column 1 can be closely fitted.

[0040] like Figure 3As shown, the first steel plate 21 and the third steel plate 23 are arranged opposite to each other. The second steel plate 22 and the fourth steel plate 24 are arranged opposite to each other. The thickness of the second steel plate 22, the third steel plate 23 and the fourth steel plate 24 are kept consistent so as to ensure the uniformity of the force on the concrete support column 1. The steel corbel 4 is welded to the first steel plate 21. The steel corbel 4 directly transfers the load of the steel beam 101 to the first steel plate 21. The first steel plate 21 is subjected to a greater load than the second steel plate 22, the third steel plate 23 and the fourth steel plate 24.

[0041] Preferably, the thickness of the first steel plate 21 is greater than that of the second steel plate 22 , the third steel plate 23 and the fourth steel plate 24 , so as to ensure sufficient welding strength between the steel corbel 4 and the first steel plate 21 , thereby ensuring the safety and stability of load transfer.

[0042] Furthermore, the support mechanism for concrete construction provided by the utility model also includes a bonding member. The bonding member is poured at the connection between the steel cylinder 2 and the concrete support column 1 to increase the stability of the connection between the steel cylinder 2 and the concrete support column 1, so that the steel cylinder 2 and the concrete support column 1 are formed into one body.

[0043] Optionally, the bonding member is a cement-based grouting material or a structural adhesive.

[0044] The support mechanism provided by the utility model is applied to concrete buildings, such as Figure 1 and Figure 2 As shown, the steel corbel 4 includes a body 41, a top plate 42 and a bottom plate 43. The body 41 is welded to the steel cylinder 2. The sliding support 5 is connected to the top plate 42. The top plate 42 and the bottom plate 43 are arranged in parallel in the horizontal direction, and the top plate 42 and the bottom plate 43 are respectively welded to the top and bottom ends of the body 41. Stiffening ribs are respectively welded on opposite sides of the body 41.

[0045] It is understandable that one side of the body 41 is welded to the first steel plate 21, so that the steel corbel 4 cantilevers over the concrete support column 1. The length and width of the top plate 42 are greater than the bottom plate 43. The top plate 42 and the bottom plate 43 are respectively welded to the top and bottom ends of the body 41, and are formed as a whole with the body 41. Among them, stiffening ribs are respectively welded on the opposite sides of the body 41 to increase the overall support strength of the steel corbel 4.

[0046] like Figure 1 As shown, the sliding support 5 is connected to the top plate 42 to transfer the load of the steel beam 101 to the steel corbel 4.

[0047] Specifically, Figure 4 As shown, the stiffening ribs include horizontal stiffening ribs 44 and vertical stiffening ribs 45. The horizontal stiffening ribs 44 and the vertical stiffening ribs 45 are arranged crosswise, and the two ends of the vertical stiffening ribs 45 are welded to the top plate 42 and the bottom plate 43 respectively.

[0048] It is understandable that horizontal stiffening ribs 44 are welded on opposite sides of the body 41 to increase the horizontal support strength of the steel corbel 4. The number of the horizontal stiffening ribs 44 can be adaptively increased or decreased according to the height of the body 41.

[0049] Furthermore, if Figure 4 As shown, vertical stiffening ribs 45 are welded on opposite sides of the body 41. The top and bottom ends of the vertical stiffening ribs 45 are welded to the top plate 42 and the bottom plate 43 respectively, so as to increase the vertical support strength of the steel corbel 4. The horizontal stiffening ribs 44 and the vertical stiffening ribs 45 are welded and connected, and are arranged crosswise to increase the overall strength of the steel corbel 4.

[0050] The number of the vertical stiffening ribs 45 can be adaptively increased or decreased according to the length of the body 41 .

[0051] Furthermore, in some embodiments, Figure 1 As shown, the bottom plate 43 and the horizontal stiffening ribs 44 are respectively welded to the steel cylinder 2. A connecting edge is provided on one side of the steel cylinder 2 close to the steel corbel 4. The top plate 42 is welded to the connecting edge.

[0052] It is understandable that the bottom plate 43 and the horizontal stiffening ribs 44 are respectively welded to the first steel plate 21 , which can increase the integrity of the connection between the steel corbel 4 and the steel cylinder 2 .

[0053] Specifically, the connection edge is arranged at the top of the first steel plate 21. The connection edge is arranged horizontally. The top plate 42 and the connection edge are located at the same elevation. The top plate 42 is welded to the connection edge on one side close to the steel cylinder 2 to enhance the stability of the connection between the steel corbel 4 and the steel cylinder 2, so as to stably transfer a part of the load on the top of the steel corbel 4 to the top of the steel cylinder 2 through the top plate 42, thereby ensuring the uniformity of the force on the steel cylinder 2.

[0054] The utility model provides a support mechanism for concrete buildings, such as Figure 2 As shown, the sliding support 5 includes a first fixing plate 51, a second fixing plate 52, a connecting plate 53 and a rubber pad 54. The first fixing plate 51 is used to be fixed to the steel beam 101. The connecting plate 53 is fixed to the first fixing plate 51. The second fixing plate 52 is fixed to the steel corbel 4. The rubber pad 54 is sandwiched between the first fixing plate 51 and the second fixing plate 52. The rubber pad 54 has a groove, and the connecting plate 53 is received in the groove.

[0055] It is understandable that the sliding support 5 can reduce the impact of earthquakes or other external vibrations on the building through the property that the two ends can slide relative to each other. The sliding support 5 can reduce the vibration response of the building when the building is subjected to earthquakes, mechanical vibrations or wind loads. In addition, the structural deformation of the building caused by uneven settlement or foundation settlement can also be compensated by the sliding support 5.

[0056] Specifically, in this embodiment, Figure 2 As shown, the first fixing plate 51 is fixed to the steel beam 101. The connecting plate 53 is protruding from the steel beam 101. The side of the connecting plate 53 close to the rubber pad 54 is arc-shaped. The second fixing plate 52 is fixed to the top plate 42. The rubber pad 54 is fixed between the connecting plate 53 and the second fixing plate 52, and at least a portion of the connecting plate 53 is accommodated in the groove.

[0057] Thus, the first fixing plate 51 transfers the load of the steel beam 101 to the connecting plate 53. Under the action of external vibration, the connecting plate 53 can be displaced to a certain extent in the groove, so that the sliding support 5 can adapt to the displacement of the steel corridor 100 relative to the steel bracket 4. The rubber pad 54 has good elasticity and buffering performance, and can absorb the energy generated by earthquakes or mechanical vibrations, thereby reducing the vibration amplitude of the steel corridor 100 and protecting the structural safety of the steel corridor 100.

[0058] Furthermore, if Figure 1 and Figure 2 As shown, in some embodiments, the support mechanism for concrete construction provided by the utility model further includes a limit plate 6. The limit plate 6 is fixed to the steel bracket 4. The limit plate 6 is used to limit the relative displacement of the first fixing plate 51 and the second fixing plate 52 in extreme cases.

[0059] It is understandable that the limit plate 6 is fixed to the top plate 42 and is located at the outer edge of the top plate 42. The second fixed plate 52 is located in the area surrounded by the first steel plate 21, the top plate 42 and the limit plate 6. When the steel corridor 100 is subjected to extreme effects such as a large earthquake or large mechanical vibration, the limit plate 6 is used to limit the sliding support 5 to control the displacement between the steel beam 101 and the steel corbel 4 within a certain range, prevent the steel beam 101 from falling off the steel corbel 4, and ensure the safety and stability of the steel corridor 100.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
