Description

Technical Field

[0001] The utility model relates to a combined structure of a sidewalk stone railing and a base. Background Art

[0002] With the frequent occurrence of bridge railings breaking, overturning and other safety accidents in my country in recent years, the safety of bridge sidewalk railings has received widespread attention from the society. The railings that have such accidents are mostly made of stone, and stone railings are a traditional form of railings with high recognition in the engineering industry. They are simple, stable, and have low maintenance costs. However, the size of the stone railing columns required by the specification calculation is too large, which affects the appearance. The railing construction method is basically that the manufacturer makes it and then transports it to the site for installation. Therefore, there are common practical problems such as the column and the base are not connected in place, the column size is reduced after considering the landscape requirements, but the calculation is difficult to pass, and the concrete around the slot is easy to crush. How to solve the safety problem of stone railings has become a major difficulty in design. At present, there are two main solutions: increasing the size of the column and inserting reinforcement at the bottom. The first one makes the railing look thick and has a greater impact on the landscape of urban bridges; the second one is that the reinforcement is located in the middle of the column section, which greatly reduces the efficiency of the steel bars. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a combined structure of a sidewalk stone railing and a base, which not only meets the force requirements of the railing itself, but also solves the problem that the column size is too large and the concrete around the square slot is easy to break, resulting in connection failure.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problems is: a combined structure of a stone sidewalk railing and a base, comprising a railing column, a base, a sidewalk slab and embedded dowels; a slot is arranged in the base; the bottom of the railing column is a column base, the column base is arranged in the slot, the bottom surface of the column base is arranged on the bottom surface of the slot, and the railing column and the base are fixed together by embedded dowels; the sidewalk slab is installed on the base; it is characterized in that: the bottom surface of the column base and the bottom surface of the slot are both stepped surfaces; structural adhesive is filled between the column base and the slot; the column base protrudes toward the sidewalk slab, and embedded dowels are also arranged in the part of the column base protruding toward the sidewalk slab.

[0005] The railing posts of the utility model are made of stone.

[0006] The base described in the utility model is made of concrete material.

[0007] The structural adhesive described in the utility model adopts Class A adhesive.

[0008] The slot described in the utility model has only left and right side walls but no front and rear side walls.

[0009] Compared with the prior art, the utility model has the following advantages and effects:

[0010] 1. It solves the problem that the existing conventional column dowels can only be located in the middle of the column and the efficiency of using steel bars is poor. The column base extends outward in the direction of the sidewalk slab, making it larger in area and convenient for dowel construction. More importantly, the steel bars can be located on the main force-bearing side (sidewalk slab side), effectively exerting the force-bearing performance of the steel bars. Through bending calculation, the cross-sectional size of the column above the sidewalk on the bridge deck can be effectively reduced. In addition, the bottom surface of the column base and the top surface of the base are both stepped surfaces, which reduce the overturning arm and improve the anti-overturning performance of the column. There is no need to set up a traditional square peripheral slot. Structural adhesive is filled between the column base and the slot, which makes the connection performance better and avoids the situation of crushing failure caused by the thin concrete around the slot. In summary, the utility model solves the practical problems of large column size, low dowel efficiency, and easy-to-break concrete around the square slot that leads to connection failure. The technical solution is convenient to construct, highly reliable, and more beautiful.

[0011] 2. The utility model has low construction difficulty and strong adaptability, and can effectively solve practical engineering problems in safety and durability that are often encountered with stone railings on bridges. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0016] The embodiment of the utility model comprises a railing column 1, a base 3, a structural adhesive 4, a pre-embedded dowel 5 and a sidewalk slab 6.

[0017] The railing column 1 is made of stone with a strength of MU120.

[0018] The base 3 is made of concrete material with a grade of C30; a slot is provided in the base 3 .

[0019] The bottom of the railing column 1 is a column base 2, which is arranged in the slot, and the bottom surface of the column base 2 is arranged on the bottom surface of the slot. The railing column 1 and the base 3 are also fixed together by embedded dowel bars 5, and the embedded dowel bars 5 are HRB400. The sidewalk slab 6 is installed on the base 3.

[0020] The bottom surface of the column base 2 and the bottom surface of the slot are both stepped surfaces; the column base 2 and the slot are filled with structural adhesive 4, and the structural adhesive 4 adopts Class A adhesive. The column base 2 protrudes in the direction of the sidewalk slab 6; the embedded dowel bar 5 is located in the column base 2, and the part of the column base 2 protruding in the direction of the sidewalk slab 6 is also provided with the embedded dowel bar 5. In this way, the exposed cross-sectional size of the column can be reduced by calculation, and the practical problems such as the large size of the column, the low efficiency of the dowel bar, and the concrete around the square slot is easy to break and cause the connection failure are solved. This technical solution is convenient to construct, reasonable in structure, and more beautiful. Then, the stone railing balustrade 8 and the stone railing handrail 9 are fixed by connecting the tenon 7 between each railing column 1.

[0021] If the size of the base 3 is relatively small, for example, the top size of the base 3 is about 30 cm wide, and the size of the railing column 1 is 25*25 cm, and the slot is about 20*20 cm, then the space of a circle of the slot will be very thin, and only 5 cm will be left on the front and rear sides of the slot, and sometimes less than 5 cm. It is useless to have a circle of thin steel bars inside, and the concrete will easily crack. In this case, the slot can be set to have only left and right side walls, without front and rear side walls, because the utility model has reduced the overturning arm through the stepped surface structure and improved the anti-overturning performance of the column, and the lack of front and rear side walls in the slot does not affect the anti-overturning performance of the utility model.

[0022] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
