Description

Technical Field

[0001] This utility model belongs to the technical field of railing installation structure, specifically relating to a railing installation structure with an embedded inverted curb. Background Technology

[0002] A retaining wall is a key structure in building construction used for waterproofing and water blocking. When making a retaining wall, it is necessary to install reinforcing bars on the surface of the original concrete structure to improve the structural strength of the retaining wall and effectively prevent the concrete of the retaining wall from cracking. A railing is a building component used for safety protection. When installing railings on balconies, expansion bolts are usually used to fix the railings to the retaining wall of the balcony.

[0003] Chinese patent CN221779240U discloses a connection device for the uprights and base of a railing. This design includes a U-shaped connecting piece. The top of the U-shaped connecting piece is inserted into the bottom cavity of the rectangular upright of the railing. The lower part of the U-shaped connecting piece and the rectangular upright are set in pre-embedded holes in a reinforced concrete base. Multiple connection holes are formed in the pre-embedded holes. The horizontal flanges of the U-shaped connecting piece are connected and fixed to the corresponding connection holes using expansion bolts. The left and right vertical plates of the U-shaped connecting piece are fixedly connected to the rectangular upright by self-tapping screws passing through the side walls of the rectangular upright. This design is suitable for factory-fixed connections between the uprights and base of railings, and on-site installation using expansion bolts can improve construction progress.

[0004] The above scheme requires the installation of a formwork on top of the reinforced concrete base to create pre-embedded holes when pouring the concrete. Before installing the expansion bolts, drilling equipment is needed to drill holes in the pre-embedded holes according to the installation position of the riser. After drilling, the holes need to be cleaned repeatedly with a brush and an air gun before the expansion bolts can be installed. As a result, the above scheme requires a lot of preparation work on the construction site before the railings are installed. Utility Model Content

[0005] The present invention aims to provide an inverted retaining wall installation structure to reduce the preparatory work required on the construction site before installing the retaining wall.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An embedded railing installation structure includes a reverse curb body, a railing body, and a movable rod. A channel steel bar is fixedly installed along the length of the top of the reverse curb body. A wedge-shaped base is fixedly connected to the bottom of one inner sidewall of the channel steel bar. The railing body includes an installation rod and two vertical pipes. The installation rod is disposed within the channel steel bar, and its top ends are fixedly connected to the two vertical pipes. The movable rod is disposed within the channel steel bar on the side of the installation rod near the base. The bottom of the movable rod on the side near the base has an inclined surface that mates with the base. A bolt is threaded into the top of the base, and the bolt has a cap on its top. The cap can push the movable rod downwards along the inclined surface of the base.

[0008] The principle and effects of this technical solution:

[0009] When constructing the main body of the inverted retaining wall, the channel steel strip is fixedly connected to the reinforcing steel inside the main body of the inverted retaining wall. When installing the railing, the mounting rod is inserted into the channel steel strip and made to contact the inner side wall of the channel steel strip away from the base. Then, the movable rod is placed in the channel steel strip on the side of the mounting rod near the base, and the bolt is threaded into the base. Then, the bolt is rotated and moved downward. The bolt cap pushes the movable rod to move along the inclined surface of the base. During the downward movement of the movable rod, it pushes the mounting rod against the inner side wall of the channel steel strip away from the base, thereby clamping and fixing the mounting rod.

[0010] With the above setup, the base and channel steel bars are connected in the factory. During construction, only the channel steel bars need to be fixedly installed on the top of the main body of the inverted curb. No additional drilling or hole cleaning is required. The main body of the railing can be fixed by inserting bolts into the top of the base. This simplifies the operations on the construction site and improves construction efficiency and project completion quality.

[0011] In this utility model, a baffle is fixedly provided on the top of the other inner side wall of the channel steel bar, and a clamping plate is fixedly provided on the bottom of the mounting rod near the baffle.

[0012] In this utility model, a retaining plate is fixedly provided at the bottom of the mounting rod near the base, and a protruding strip is provided at the top of the movable rod near the mounting rod.

[0013] The principle and effects of this technical solution:

[0014] After inserting the mounting rod into the channel steel bar, first slide the mounting rod so that the clamping plate on the side of the mounting rod near the baffle is locked in the gap between the baffle and the inner bottom wall of the channel steel bar. Then, use bolts to push the movable rod to move along the inclined surface of the base. When the side wall of the movable rod and the inner side wall of the channel steel bar away from the base clamp the clamping plates on both sides of the mounting rod respectively, the protrusion moves to above the clamping plate near the base.

[0015] By using the above-mentioned settings, the baffle and the convex strip respectively restrict the upward movement of the corresponding card plate, thereby preventing the installation rod from moving upward, further improving the fixing effect of the device on the main body of the railing, and improving the safety and stability of the device.

[0016] In this utility model, the top of the base is provided with a screw hole, the movable rod is provided with a through groove that runs vertically through the top and bottom, the length direction of the through groove is perpendicular to the length direction of the channel steel bar, the bolt slides through the through groove and is threaded into the screw hole, and the bottom of the bolt cap can abut against the movable rod.

[0017] In this utility model, the top of the movable rod is recessed with a countersunk hole on the outer periphery of the through groove, the bolt cap is located in the countersunk hole, and the bottom of the bolt cap can abut against the bottom wall of the countersunk hole.

[0018] The above setup achieves the goal of using the downward-moving bolt to push the movable rod along the inclined surface of the base, causing the bolt cap to push the bolt downwards.

[0019] In this utility model, a decorative panel is also included, which covers the top surface of the inverted curb body, and an adhesive layer is provided between the decorative panel and the inverted curb body.

[0020] In this utility model, multiple sets of decorative panels are provided between the two risers. The decorative panel near the riser is provided with a notch that mates with the riser. There are adhesive strips between the riser and the notch, and between two adjacent decorative panels.

[0021] The above-mentioned design prevents rainwater from flowing into the channel steel bars, thus preventing rust on the channel steel bars, base, bolts, and other components, and extending the service life of the device.

[0022] In this invention, through holes are formed at the same height on the two adjacent outer side walls of the riser. This arrangement allows fasteners to be passed through the through holes on the risers where the two railing bodies are close together, thus connecting the two adjacent railing bodies and enhancing the overall integrity and stability of the device.
