Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and particularly relates to a concrete structure connection node with a sliding support. Background Art

[0002] The connection structure between two or more relatively independent concrete structures requires multi-faceted considerations, including: 1) the shear force and braking force generated by the relative displacement between independent concrete components; 2) the shock absorption and buffering requirements caused by the horizontal displacement and end deflection between concrete components under load; 3) the dimensional errors that are common during the casting and molding of concrete components, and the adverse effects caused by these errors being amplified at the connections between structural components, as well as the creep of concrete components themselves caused by environmental factors.

[0003] Currently, the more traditional connection form between two or more relatively independent concrete structures is to connect the two independent concrete components into one by using the integral molding method of steel bar bending anchors, and to improve the mechanical strength of the node through material and structural treatment to resist the adverse connection effects generated between the independent concrete structures. However, this treatment method usually leads to material waste or complicated construction methods. Summary of the Invention

[0004] In response to the deficiencies in the prior art, the present invention provides a concrete structure connection node with a sliding support to solve the problems of material waste or complicated construction methods in the prior art using the method of integrally forming steel bar bent anchors.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A concrete structure connection node with a sliding support is arranged between concrete component I and concrete component II, where concrete component I is located above concrete component II. A first embedded part is embedded at the bottom of concrete component I, and a second embedded part opposite to the first embedded part is embedded at the top of concrete component II. A rubber support is provided between the first embedded part and the second embedded part.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] The connection nodes provided by this solution create a new top-down connection component, formed by combining the first embedded part, the second embedded part, and the rubber bearing. This approach is simple to construct and solves the connection problem between independent concrete components, alleviating the adverse effects of relative displacement between components. It also mitigates the adverse effects of dimensional errors in concrete components during the casting process. Furthermore, it provides a buffering and shock-absorbing effect, taking into account creep of concrete components caused by environmental factors such as temperature, the effects of braking forces, and horizontal displacement and end deflection under load. This approach can be used to connect large concrete components in large-scale buildings, withstand relatively complex working conditions, and meet the high requirements for freedom between relatively independent concrete components.

[0009] Furthermore, the first embedded part includes a first support leg and a first steel plate. The first support legs are provided in plurality and are evenly distributed vertically on the first steel plate. The first support legs and the first steel plate are buried in the concrete component I, and the bottom surface of the first steel plate is exposed from the concrete component I.

[0010] Beneficial effect: By providing multiple first legs, the connection strength between the first embedded part and the concrete component I is improved.

[0011] Furthermore, the second embedded part includes a second support leg and a second steel plate. The second support legs are provided in plurality and are evenly distributed vertically on the second steel plate. The second support legs and the second steel plate are both buried in the concrete component II, and the top surface of the second steel plate is exposed from the concrete component II.

[0012] Beneficial effect: By providing multiple second legs, the connection strength between the second embedded part and the concrete component II is improved.

[0013] Furthermore, the area of ​​the second steel plate is greater than the area of ​​the first steel plate.

[0014] Beneficial effect: to improve the supporting capacity of the second embedded part.

[0015] Furthermore, an adjusting steel plate is fixed on the second steel plate.

[0016] Beneficial effects: On the one hand, in order to facilitate the installation of rubber bearings, on the other hand, since they need to be selected according to specifications, their sizes need to be calculated based on the force and degree of freedom of the connection nodes. Therefore, the gap between concrete component I and concrete component II usually needs to exceed the height of the rubber bearing. Therefore, an adjustment steel plate is set on the second steel plate, which not only facilitates installation, but also allows the rubber bearing to be statically pressed between the first steel plate and the second steel plate.

[0017] Furthermore, the rubber support is bonded between the adjusting steel plate and the first steel plate.

[0018] Beneficial effect: The bonding method can improve the connection strength between the rubber support, the adjustment steel plate and the first steel plate.

[0019] Furthermore, the rubber bearing is a cylinder.

[0020] Beneficial effects: Since rubber bearings are widely used in bridge construction and have relatively complete usage specifications, this solution can perform calculations and analysis based on the usage specifications and select suitable rubber bearings.

[0021] Furthermore, the adjustment steel plate includes a limiting steel plate and a tightening steel plate. The bottom of the limiting steel plate is provided with a plurality of horizontally arranged slots, and the plurality of slots are distributed at equal intervals. The top of the tightening steel plate is integrally formed with a plurality of clips corresponding to the slots.

[0022] Beneficial effect: With this arrangement, during installation, first bond the bottom of the rubber support to the top of the limiting steel plate, then coat the top of the rubber support with adhesive, and then place it in the gap. Move the limiting steel plate upward to bond the top of the rubber support to the bottom of the first steel plate. After the rubber support is completely bonded to the bottom of the first steel plate, insert the tightening steel plate into the bottom of the limiting steel plate, with the card strip inserted into the card slot. This process continuously squeezes the rubber support, and then the tightening steel plate is welded to the second steel plate. This method can prevent the adhesive on the top of the rubber support from being transferred to the first steel plate due to friction during the process of entering the gap, thereby reducing the adhesive between the rubber support and the first steel plate and reducing the connection strength.

[0023] Furthermore, the distance between the bottom of the limiting steel plate and the top of the second steel plate is D1, and the thickness of the pressing steel plate is D2, wherein D1<D2.

[0024] Beneficial effect: With this arrangement, when inserting and tightening the steel plate, the rubber support is continuously squeezed, causing the rubber support to produce a certain deformation and press tightly between the first steel plate and the second steel plate, thereby improving the buffering effect of the connection node.

DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below with reference to the accompanying drawings, and specific implementation methods will be given.

[0031] Example 1:

[0032] Basically Figure 1 and Figure 2 As shown, a concrete structure connection node with a sliding support is arranged between concrete component I1 and concrete component II2. Concrete component I1 is located above concrete component II2. When it is necessary to connect with the side wall of concrete component II2, a corbel 3 is cast on the side wall of concrete component II2 so that the corbel 3 is located below concrete component I1. A first embedded part is buried at the bottom of concrete component I1. The first embedded part includes a first support leg 10 and a first steel plate 11. A plurality of first support legs 10 are provided and are vertically evenly distributed on the first steel plate 11. The first support leg 10 and the first steel plate 11 are buried in the concrete component I1, and the bottom surface of the first steel plate 11 is exposed from the concrete component I1.

[0033] A second embedded part is buried at the top of the concrete component II2, which is opposite to the first embedded part. The second embedded part includes a second support leg 12 and a second steel plate 13. There are several second support legs 12, which are evenly distributed vertically on the second steel plate 13. The second support legs 12 and the second steel plate 13 are both buried in the concrete component II2, and the top surface of the second steel plate 13 is exposed from the concrete component II2. The area of ​​the second steel plate 13 is larger than that of the first steel plate 11.

[0034] An adjusting steel plate 14 is welded on the top of the second steel plate 13 , a rubber support 15 is provided between the adjusting steel plate 14 and the first steel plate 11 , adhesive is coated between the rubber support 15 and the adjusting steel plate 14 and the first steel plate 11 , and the rubber support 15 is cylindrical.

[0035] Since the rubber bearing 15 needs to be selected according to the specifications, its size needs to be calculated based on the force, degree of freedom, etc. of the connection node. Therefore, the gap between the concrete component I1 and the concrete component II2 usually exceeds the height of the rubber bearing 15. Therefore, during installation, first select an adjustment steel plate 14 of appropriate thickness based on the selected rubber bearing 15, glue the bottom of the rubber bearing 15 to the adjustment steel plate 14, then place the adjustment steel plate 14 and the rubber bearing 15 into the gap, weld the adjustment steel plate 14 to the second steel plate 13, and glue the top of the rubber bearing 15 to the first steel plate 11.

[0036] Example 2:

[0037] The difference from Example 1 is: Figure 3 As shown, the adjusting steel plate 14 includes a limiting steel plate 141 and a tightening steel plate 142. A plurality of horizontally arranged slots are provided at the bottom of the limiting steel plate 141, and the slots are evenly spaced. A plurality of clips 143 corresponding to the slots are integrally formed on the top of the tightening steel plate 142. During installation, the bottom of the rubber support 15 is first bonded to the top of the limiting steel plate 141, and then the top of the rubber support 15 is coated with adhesive and then placed in the gap. The limiting steel plate 141 is moved upward to tighten the rubber support. The top of the seat 15 is bonded to the bottom of the first steel plate 11. At this time, the distance between the bottom of the limiting steel plate 141 and the top of the second steel plate 13 is D1, and the thickness of the tightening steel plate 142 is D2, where D1 is less than D2. After the rubber support 15 is completely bonded to the bottom of the first steel plate 11, the tightening steel plate 142 is inserted into the bottom of the limiting steel plate 141, and the clip 143 is inserted into the slot. This process continuously squeezes the rubber support 15, and then the tightening steel plate 142 is welded to the second steel plate 13.

[0038] Example 3:

[0039] The difference from Example 2 is: Figure 4 As shown, the top and bottom of the rubber support 15 are both in an arc shape that is concave toward the inside of the rubber support 15. This arrangement reduces the overflow of adhesive during the extrusion bonding process, thereby improving the connection strength between the rubber support 15 and the adjustment steel plate 14 and the first steel plate 11. In addition, if the top and bottom of the rubber support 15 are both flat, then during the process of inserting the tightening steel plate 142 to drive the rubber support 15 to deform, the deformation of the rubber support 15 will be concentrated in the middle, causing stress concentration, resulting in a decrease in the fatigue strength of the rubber support 15. However, with this solution, during the process of inserting the tightening steel plate 142 to drive the rubber support 15 to deform, since the top and bottom of the rubber support 15 are both in an arc shape that is concave toward the inside of the rubber support 15, a certain deformation margin is reserved for the rubber support 15 to be squeezed, so that the entire rubber support 15 is subjected to the extrusion force, reducing the occurrence of stress concentration.
