Description

Technical Field

[0001] The utility model belongs to the technical field of building supports, and in particular relates to a building support structure. Background Art

[0002] Earthquake-resistant structure is an important structure in building structure, which can protect the building structure when an earthquake occurs.

[0003] Currently, mainstream earthquake-resistant structures utilize seismic isolation bearings. Specifically, the main structure of the isolation bearings includes seismic isolation rubber pads. By attaching the base of the isolation bearings to the pile foundation and the top to the building structure's pile foundation, the isolation bearings achieve earthquake resistance. When an earthquake occurs, the building structure shakes due to the flexible connection between the isolation bearings and the pile foundation, thus buffering the vibration energy.

[0004] Currently, the bottom of the seismic isolation bearing is embedded in the steel cage structure of the pile foundation through an embedded structure. The main structure includes an embedded mounting plate and hook bars welded to the bottom of the embedded mounting plate. However, the gripping strength of this embedded structure and the pile foundation steel cage is not high. The main reason is that the hook bar of the single structure does not have enough hooking strength. Therefore, when an earthquake occurs, the stability between the twisted seismic isolation bearing and the pile foundation structure is not high, and its seismic resistance is insufficient. When the earthquake amplitude is large, it is found under simulation test conditions that the embedded structure on the twisted seismic isolation bearing and the pile foundation steel cage are easy to loosen. Therefore, the seismic resistance effect of the current seismic isolation bearing still needs to be improved. Utility Model Content

[0042] Example 1

[0043] like Figure 1-5 As shown, a building support structure includes a seismic isolation support mechanism 1, which is a conventional seismic isolation support disclosed in the prior art. The main structure includes a seismic isolation rubber seat 11, a lower embedded plate mechanism 2 installed at the bottom position of the seismic isolation rubber seat 11, and an upper steel cage mechanism 3 installed at the top position of the seismic isolation rubber seat.

[0044] The lower embedded plate mechanism 2 is installed in the steel cage on the pile foundation and is fixedly connected to the pile foundation after subsequent concrete pouring.

[0045] In order to increase the stability of the connection between the lower embedded plate mechanism 2 and the pile foundation steel cage, and to solve the problem of increasing the stability between the seismic isolation support mechanism 1 and the pile foundation during the torsion process, the above-mentioned lower embedded plate mechanism 2 includes a lower embedded plate 13, and the bottom edge of the lower embedded plate 13 is fixedly connected with a plurality of grabbing bars.

[0046] Specifically, a plurality of first gripping ribs 21 are welded on the front and rear sides of the bottom of the lower embedded plate 13; a plurality of second gripping ribs 26 are welded on the left and right sides of the bottom of the lower embedded plate 13; and a hook portion is integrally formed at the bottom of the first gripping ribs 21 and the second gripping ribs 26.

[0047] During construction, the hooks of the first and second gripping bars 21, 26 are hooked onto the steel cage and secured with wire. The rectangular cage structure formed by the rectangularly distributed first and second gripping bars 21, 26 increases the connection stability with the steel cage.

[0048] At the same time, in order to further tighten the steel cage of the pile foundation, the above-mentioned lower embedded plate mechanism 2 also includes a core pulling structure arranged on the inner side of the grabbing bar, and the core pulling structure includes a core pulling plate 22, and a plurality of tensioning bars are fixedly connected to the core pulling plate 22, and the tensioning bars are hung on the grabbing bar.

[0049] Specifically, the core plate 22 is in the shape of an I-beam; a plurality of first tensioning bars 23 hanging on the first grabbing bars 21 are fixedly connected to the front and rear side walls of the core plate 22; a plurality of second tensioning bars 24 hanging on the second grabbing bars 26 are fixedly connected to the left and right side walls of the core plate 22.

[0050] Similarly, the ends of the first and second tie bars 23, 24 are each integrally formed with hooks for tensioning. These hooks are hooked onto the pile foundation's steel cage structure. The core plate 22 secures the center of the pre-embedded structure to the pile foundation's steel cage structure. In this manner, the center and surrounding edges of the pre-embedded structure are secured to the pile foundation's steel cage structure via the first gripping bars 21, second gripping bars 26, first tie bars 23, and second tie bars 24, respectively.

[0051] Several main tie bars 25 are fixedly connected to the upper and lower ends of the front and rear sidewalls of the core plate 22. The outer ends of the main tie bars 25 are integrally formed with hooks. The main tie bars 25 are larger in diameter than the first gripping bars 21, second gripping bars 26, first tie bars 23, and second tie bars 24, and serve as the primary tensioning and fixing mechanism.

[0052] Example 2

[0053] like Figure 1-5As shown, this embodiment is based on the structure of embodiment 1. Similarly, in order to increase the connection stability with the building structure, the above-mentioned upper steel cage mechanism 3 includes a mounting plate 11 fixedly connected to the top position of the seismic isolation rubber seat, and the top of the mounting plate 11 is fixedly connected to the steel cage structure.

[0054] The steel cage structure includes a plurality of longitudinal bars 31 and a plurality of stirrups 32 spaced apart from each other; the stirrups 32 are sleeved around the outside of the longitudinal bars 31 .

[0055] At the same time, a main pulling structure 33 is provided at the center of the cage cavity of the steel cage structure. The main pulling structure 33 is used to pull the steel cage structure, thereby improving the stability of the steel cage structure and reducing the looseness between the twisted seismic isolation support mechanism 1 and the building structure during an earthquake.

[0056] Specifically, the main pulling structure 33 includes an I-beam 331; a number of short ribs 333 are welded to the front and rear side walls of the I-beam 331; the short ribs 333 are welded to the longitudinal ribs 31; a number of long ribs 332 are welded to the left and right side walls of the I-beam 331, and the long ribs 332 are welded to the longitudinal ribs 31.

[0057] In this way, the I-beam 331 is used as the central pulling skeleton to pull the steel cage structure. Under the I-beam 331 structure, the long and short bars 333 are welded and fixed to the steel cage structure to increase the stability of the steel cage structure.

[0058] After the subsequent pouring of concrete, it becomes one with the main structure of the building.

[0059] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples.
