[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Reference Figure 2-6A positioning device for installing an anti-seismic bearing for a building is shown, comprising a mounting steel plate 1, on which a plurality of positioning screw holes 11 for connecting bolts are opened, and the plurality of positioning screw holes 11 are distributed along the circumference of the center point of the mounting steel plate 1;

[0026] A through hole is opened in the middle of the mounting steel plate 1. The diameter of the through hole is the same as the maximum diameter of the bottom of the seismic support, and a mounting guide surface 12 is provided on the upper part of the through hole of the mounting steel plate 1;

[0027] A positioning steel plate 2 is detachably connected to the inner side of the through hole of the mounting steel plate 1 . A casting hole is provided in the middle of the positioning steel plate 2 . A plurality of positioning grooves 21 are provided on the upper surface of the positioning steel plate 2 and are distributed in an array along the circumference of the central axis of the positioning steel plate 2 .

[0028] Based on the above structure, by setting the positioning device as two detachable main bodies, namely the installation steel plate 1 and the positioning steel plate 2, when the reserved positioning hole is initially cast, the positioning steel plate 2 can be connected to the installation steel plate 1, and it can be restored to a positioning device basically the same as the positioning steel plate in the prior art, so that the bolts are screwed into the positioning screw holes 11 to cast the reserved positioning holes. When the casting is completed, it is only necessary to remove the positioning steel plate 2 and install the installation steel plate 1 on the cast base again. At this time, it is only necessary to align the bottom of the seismic bearing with the approximate middle position of the installation steel plate 1. During the lowering process of the seismic bearing, In the process, the lower end of the seismic bearing first contacts with the installation guide surface 12 on the installation steel plate 1, and the installation guide surface 12 guides the seismic bearing into the through hole of the installation steel plate 1. Since the center of the seismic bearing itself is fixed, when the seismic bearing is in the through hole of the installation steel plate 1, its center axis has completed the calibration positioning. After that, only the installation steel plate 1 needs to be removed, so as to facilitate the use of the positioning device for the installation of the seismic bearing for the building to perform reserved hole positioning for the installation of the seismic bearing and to position the center axis during the installation process, thereby expanding the function of the positioning device, achieving better use effect, and being more practical.

[0029] Furthermore, a first threaded portion 13 is provided at the lower portion of the through hole of the mounting steel plate 1, and a second threaded portion 22 adapted to the first threaded portion 13 is provided on the peripheral side of the positioning steel plate 2. The mounting steel plate 1 and the positioning steel plate 2 are detachably connected by threads through the first threaded portion 13 and the second threaded portion 22.

[0030] Furthermore, a pouring pipe 3 is detachably connected to the upper end of the positioning steel plate 2. The height of the pouring pipe 3 is higher than the thickness of the mounting steel plate 1. A pouring pipe guide surface 31 is provided on the inner side of the upper end of the pouring pipe 3. Through the provision of the pouring pipe 3, the pouring pipe can be guided and the pouring pipe can be limited during the pouring process, so that the concrete flowing out of the pouring pipe always enters through the pouring hole on the positioning steel plate 2. This not only facilitates the alignment of the pouring pipe, but also avoids the pollution of the positioning steel plate 2 or the mounting steel plate 1 caused by concrete splashing during the pouring process.

[0031] Furthermore, a sealing cover 4 is provided on the top cover of the casting pipe 3, and a leveling plug 41 is integrally formed at the lower end of the sealing cover 4 and is plugged in the casting pipe 3. The lower end surface of the leveling plug 41 and the lower end surface of the positioning steel plate 2 and the lower end surface of the mounting steel plate 1 are all located in the same plane.

[0032] By setting the sealing cover 4 and the leveling plug 41, the opening of the pouring pipe 3 can be sealed after the pouring is completed, so as to prevent external debris from falling into the unsolidified matrix and affecting the mechanical properties of the matrix. At the same time, the area on the upper surface of the matrix located in the pouring hole of the positioning steel plate 2 can also be leveled, reducing the leveling area during subsequent construction and reducing the subsequent workload.

[0033] Furthermore, a plug block 32 is fixed at the lower end of the pouring pipe 3. A plurality of plug blocks 32 are provided and correspond one-to-one with a plurality of positioning grooves 21 respectively. The plug blocks 32 are inserted into the positioning grooves 21. The use of the plug blocks 32 can flexibly install or remove the pouring pipe 3, which is more convenient to use.

[0034] Furthermore, a sealing groove 14 is provided on the bottom surface of the mounting steel plate 1, and the sealing groove 14 is coaxially arranged and connected with the through hole. A sealing edge 23 with a diameter larger than the positioning steel plate 2 is formed at the lower end of the positioning steel plate 2. The sealing edge 23 forms a seal with the sealing groove 14 to prevent the poured concrete from entering the gap between the first threaded portion 13 and the second threaded portion 22 from the bottom and causing blockage, thereby ensuring that the mounting steel plate 1 and the positioning steel plate 2 will not be subject to significant wear during connection and disassembly, which is beneficial to extending the service life of the mounting steel plate 1 and the positioning steel plate 2.

[0035] Working principle of the utility model: in daily use, the positioning steel plate 2 can be first connected to the installation steel plate 1 to restore it to a positioning device that is basically the same as the positioning steel plate in the prior art, so that the bolts are screwed into the positioning screw holes 11 to cast the reserved positioning holes. During casting, the casting pipe 3 can guide the casting pipe and limit the casting pipe during the casting process, so that the concrete flowing out of the casting pipe always enters from the casting hole on the positioning steel plate 2, which is not only convenient for the alignment of the casting pipe, but also can avoid the contamination of the positioning steel plate 2 or the installation steel plate 1 by concrete splashing during the casting process. When the casting is completed, the cover 4 is covered to seal the opening of the casting pipe 3, so as to prevent external debris from falling into the unsolidified matrix and affecting the mechanical properties of the matrix. At the same time, the leveling plug 41 can level the area on the upper surface of the matrix located in the casting hole of the positioning steel plate 2, reducing the subsequent construction The leveling area during working hours can be reduced, and the subsequent workload can be reduced; after the substrate is solidified and marked, it is only necessary to remove the positioning steel plate 2 and install the mounting steel plate 1 again on the cast substrate. At this time, it is only necessary to align the bottom of the seismic bearing with the approximate middle position of the mounting steel plate 1. During the lowering process of the seismic bearing, the lower end of the seismic bearing first contacts with the mounting guide surface 12 on the mounting steel plate 1, and the mounting guide surface 12 guides the seismic bearing into the through hole of the mounting steel plate 1. Since the center of the seismic bearing itself is fixed, when the seismic bearing is in the through hole of the mounting steel plate 1, its center axis has completed the calibration positioning, and then it is only necessary to remove the mounting steel plate 1, so as to facilitate the use of the positioning device for the installation of the seismic bearing for the building to perform reserved hole positioning for the installation of the seismic bearing and to position the center axis during the installation process, thereby expanding the function of the positioning device, achieving better use effect, and being more practical.

Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
