Problems solved by technology

[0003] The stone and wooden railing columns on both sides of the bridge belong to the post-decoration construction, and it is a common practice to connect stone materials with stone tenon and stone glue. In the traditional stone column installation and construction method, the tenon and tenon structure is used. The mortise and tenon with a depth of 1 to 2 cm is fixed with cement or stone glue. If the foundation is not strong, the mortise and tenon used for fixing is too shallow, and it is easy to loosen and fall off when encountering a strong lateral force.
In the later period, the management and maintenance units often simply used stone glue or wooden nails to fix the repairs, but did not fundamentally solve the problem. Coupled with man-made damage, it eventually led to the common phenomenon of pillars loosening and falling off. Great impact on vehicle safety

Embodiment 1

[0019] (1) Planting bar embedding method

[0020] The setting method in the new project: such as figure 1 As shown, during the construction of the main body, a φ45 galvanized steel pipe 1 is pre-embedded at the center of the concrete beam 4 where the railing column 6 is to be installed. The steel tenons of the railing column 6 are used, and the center position and verticality of the buried galvanized steel pipe 1 are strictly controlled when setting.

[0021] Such as figure 1 As shown, in order to ensure the firmness of the galvanized steel pipe 1 in the concrete beam, the bottom of the galvanized steel pipe 1 is fixed by welding an "L" shaped anchor bar 3 .

[0022] (2) 6 drill holes for stone railing posts

[0023] Such as image 3 As shown, at the center position of the bottom of the railing column 6, a circular hole with a diameter of φ60 is drilled, and the depth of the circular hole is 350 mm. Then, grouting holes 7 are opened on both sides of the railing installatio...

Embodiment 2

[0028] (1) Planting bar embedding method

[0029] Setting method in the construction project: For construction projects, there is a concrete beam 4 under the general railing installation position, and a 250mm deep φ60 round hole can be directly drilled at the center of the railing installation. After the hole is cleaned with high-pressure gas, it can be directly used The prepared HGM series high-strength non-shrinkage grouting material 5 is enough to fix the φ45 galvanized steel pipe 1 on the concrete beam 4, and strictly control the center position and verticality of the buried steel pipe 1 during installation. The structure is as follows figure 2 shown.

[0030] All the other (2), (3), (4) steps are identical with embodiment 1.

Abstract

The invention discloses a planting bar grouting and anchoring construction process for an antique stone balustrade, which comprises the steps of: (1) embedding planting bars; (2) drilling in stone balusters; and (3) installing the stone balusters. According to the construction process of the invention, the problem of stability of the balusters of a bridge is fundamentally solved, the stability between the baluster and a bridge body is good, and the baluster is difficult to loosen even under the condition of damage by an external force, so that the safety of the bridge is ensured.

Description

technical field [0001] The invention relates to a construction technology, in particular to a construction technology for planting bar grouting and anchoring an antique stone railing. Background technique [0002] At present, there are many news reports about the loosening and falling off of the railings on the side of the bridge. For example, Sing Tao Global Network 2011-09-08 reported: "It cost more than 30 million yuan, and the 80 stone railings on both sides of the bridge deck fell off 26 in less than two years after it was opened to traffic. This is a serious threat to the safety of passing pedestrians.” Recently, another netizen broke the news: The bridge column on the Xiayi Bridge bridge on the east side of the intersection of Nongye East Road and Ruyi West Road in Zhengdong New District, Zhengzhou, Henan Province, is actually connected with the bridge body. It is made of glue, and as long as you push it hard, the stone pillar will fall off. [0003] The stone and wo...
