DETAILED DESCRIPTION

[0026] In order to make the technical personnel in the art better understand the technical scheme of the present application, the following will be further described in detail with reference to the drawings.

[0027] The present application provides a kind of assembly crown buckle of being convenient for installation as Figures 1-4 As shown in the figure, it includes crown buckle assembly 2 installed in the top of bearing column 1, and the top of bearing column 1 is also provided with bearing seat 3 matched with crown buckle assembly 2.

[0028] Specifically, bearing seat 3 includes base 31, and a plurality of fixing holes 32 are provided on the outer side of base 31, and the plurality of fixing holes 32 are uniformly distributed around the outer side of base 31, and the top of base 31 is also provided with positioning block 33.

[0029] In this embodiment, when bearing column 1 is constructed to the top, bearing seat 3 is prepared first. Ensure that the bottom of base 31 of bearing seat 3 and the connecting surface of the top of bearing column 1 are clean, flat, without sundries or protrusions and other factors affecting connection.

[0030] The bottom of the base 31 of the bearing seat 3 is placed on the top of the load-bearing column 1. Since the bottom of the base 31 is beveled and gradually reduced to the top of the load-bearing column 1, this shape helps to preliminarily position when placed. At this time, the positioning block 33 and the plurality of fixing holes 32 on the bearing seat 3 are in the correct position, ready for the subsequent installation of the crown buckle assembly 2.

[0031] Referring to Figures 2-3 , the crown buckle assembly 2 includes a crown buckle body 21, the bottom of the crown buckle body 1 is recessed with a docking groove 22, the docking groove 22 is matched with the bearing seat 3, and the middle of the docking groove 22 is recessed inward with a positioning groove 23, the positioning groove 23 is matched with the positioning block 33, and the crown buckle body 21 is also provided with a mounting hole 24 matched with the fixing hole 32, the mounting hole 24 and the fixing hole 32 are jointly installed with a fastening bolt 4, the crown buckle body 21 is installed on the top of the bearing seat 3, and the inner wall of the docking groove 22 and the outer wall of the base 31 leave a gap.

[0032] Specifically, the crown buckle body 21 is also provided with a mounting slot 25 at the top, and the mounting slot 25 penetrates the top of the crown buckle body 21 all around, and the outside of the mounting hole 24 is provided with a nut groove 26, and the nut groove 26 and the mounting hole 24 jointly install the fastening bolt 4.

[0033] In this embodiment, the crown buckle body 21 of the crown buckle assembly 2 is lifted and aligned with the bearing seat 3, so that the docking groove 22 at the bottom of the crown buckle body 21 is aligned with the base 31 of the bearing seat 3. In this process, the positioning groove 23 in the middle of the docking groove 22 will cooperate with the positioning block 33 on the top of the bearing seat 3, thereby achieving the preliminary positioning of the crown buckle assembly 2. This positioning method is simple and accurate, and can quickly determine the position of the crown buckle assembly 2 relative to the bearing seat 3.

[0034] Referring to Figure 4 , the fastening bolt 4 includes a fastening stud 41, which is rotationally fixed in the mounting hole 24 and the fixing hole 32, and a fastening nut 42 is further provided thereon, which is installed in the nut groove 26 and the rotation direction is limited by the nut groove 26.

[0035] Specifically, the bottom of the base 31 is fixed on the top of the load-bearing column 1, and the bottom of the base 31 is beveled and gradually reduced to the top of the load-bearing column 1.

[0036] Specifically, the plurality of fixing holes 32 are arranged on the outside of the base 31 in the same number and corresponding positions as the mounting holes 24.

[0037] Specifically, the distance between the inner wall of the docking groove 22 and the outer wall of the base 31 is 11mm.

[0038] In this embodiment, after the crown buckle body 21 is initially positioned, the fastening studs 41 of the fastening bolts 4 are sequentially inserted through the mounting holes 24 and the fixing holes 32 corresponding to the positions of the mounting holes 24 around the crown buckle body 21 and the outer side of the base 31 of the bearing seat 3. Then, the fastening nuts 42 are installed in the nut grooves 26 outside the mounting holes 24. Since the nut grooves 26 limit the rotation direction of the fastening nuts 42, workers can conveniently use tools to tighten the fastening nuts 42, thereby firmly installing the crown buckle body 21 on the top of the bearing seat 3. In this process, there is a distance of 11 mm between the inner wall of the abutment groove 22 and the outer wall of the base 31, which does not affect the connection between the crown buckle assembly 2 and the bearing seat 3 during installation and provides a certain space for subsequent possible structural deformation and the like.

[0039] In this embodiment, the installation slot 25 at the top of the crown buckle body 21 penetrates through the top of the crown buckle body 21. This installation slot 25 can be used to connect with other bridge structure components (such as beam bodies and the like). Connectors (such as bolts, clamps and the like) can be arranged in the installation slot 25 to connect the beam body and the like with the crown buckle body 21, thereby realizing the effective connection between the bearing column 1 and the beam body and the like through the crown buckle assembly 2 and completing the partial assembly of the bridge structure.

[0040] In this embodiment, through the cooperation of the positioning block 33 and the positioning groove 23 and the corresponding relationship between the mounting hole 24 and the fixing hole 32, the adjustment time during installation is greatly reduced. Compared with the traditional crown buckle installation method without such precise matching design, the assembly type crown buckle can complete the installation and positioning work more quickly, thereby improving the installation efficiency.

[0041] Further, the limitation of the rotation direction of the fastening nuts 42 by the nut grooves 26 makes the installation and tightening operation of the fastening bolts 4 more convenient. Workers do not need to spend too much time to fix the nuts to prevent them from rotating, and can more quickly complete the bolt connection between the crown buckle assembly 2 and the bearing seat 3, thereby further improving the installation speed.

[0042] In this embodiment, the slope design at the bottom of the base 31 enables the load borne by the crown buckle to be better transmitted to the bearing column 1. When the bridge bears various forces such as vehicle load and dead load, these forces are transmitted to the bearing seat 3 through the crown buckle assembly 2, and then uniformly dispersed to the top of the bearing column 1 by the slope at the bottom of the base 31 of the bearing seat 3. This load transmission mode can avoid stress concentration and improve the bearing capacity and stability of the entire bridge structure.

[0043] In this embodiment, the gap of 11 mm between the inner wall of the abutment groove 22 and the outer wall of the base 31 provides a certain space for the deformation of the structure during use. In the case of temperature changes, slight deformation of the bridge structure under load and the like, this gap can avoid damage between the crown buckle assembly 2 and the bearing seat 3 due to mutual extrusion.

[0044] Certain exemplary embodiments of this application are described herein by way of illustration, and not limitation, and it is to be understood that the application can be carried out with modifications in various forms within the spirit and scope of the application, as defined in the appended claims, without departing from the spirit of the application in its broadest form.
