Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an installation device for replaceable handrails. Background Art

[0002] Existing steel railings in buildings are generally severely corroded due to long-term exposure to the air, especially those that have not been fully treated with anti-corrosion. This corrosion not only affects the aesthetics of the railings, but more importantly, weakens their structural strength, greatly reducing the bearing capacity and stability of the railings. In areas with dense traffic, such as schools, hospitals, shopping malls, etc., continuing to use severely corroded railings will pose a great safety hazard. Once an accident occurs, the consequences will be disastrous.

[0003] Therefore, in order to ensure people's safety, it is necessary to remove the old railings. In the prior art, the railings are removed, the concrete is broken, and then the new railings are installed on the newly poured concrete flanges. However, during the removal process, some style differences between the newly poured concrete and the retained existing buildings make the overall aesthetics poor. Utility Model Content

By providing the connection plate 12 and the fixing plate, the first end face 2 of the handrail body 1 is mounted to the upper end of the connection plate 12, and the first end face 2 of the handrail body 1 is mounted to the upper end of the fixing member 6, and the concrete does not need to be broken and re-cast. It is only necessary to mount the connection plate 12 to the upper end face of the flange 4, and then mount the fixing plate to the side end face of the flange 4 to fix the handrail body 1. When disassembling, the handrail body 1 can also be easily disassembled and replaced.

[0032] like Figure 1 As shown, in this embodiment, the lower end of the connecting plate 12 is provided with an extension plate 7 extending vertically downward on a side away from the railing body 1, and the connecting plate 12 is connected to the flange 4 through a fastener passing through the extension plate 7. Specifically, the fastener passes through the extension plate 7 and is fixedly connected to the concrete flange 4. At this time, when the railing body 1 is subjected to force, the force can be transmitted to the fastener through the connecting plate 12, and the fastener passes through the extension plate 7 in the horizontal direction and is connected to the flange 4. At this time, the fastener has an upward pulling force, and the fastener has better fixation to the railing body 1. In addition, as an alternative embodiment, the fastener can pass through the connecting plate 12 from the upper end surface of the connecting plate 12 and then be connected to the flange 4.

[0033] like Figure 1 As shown, in this embodiment, two extension plates 7 are symmetrically arranged on the lower end surface of the connecting plate 12, and the two extension plates 7 are clamped on both sides of the flange 4.

[0034] like Figure 1As shown, in this embodiment, the fastener is a screw rod, which is fixed with a nut after passing through the two extension plates 7. After the screw rod passes through the two extension plates 7, both ends of the screw rod extend out of a part of the extension plate 7. The nuts are screwed on both ends of the screw rod respectively, so that the two nuts clamp the extension plate 7, making the connection more secure. In addition, as an alternative embodiment, the fastener can be set as a bolt.

[0035] like Figure 1 As shown, in this embodiment, a sealing member 8 for water isolation is provided between the extension plate 7 and the flange 4, and the sealing member 8 is provided between the extension plate 7 and the flange 4 on the side away from the railing body 1.

Specifically, the first rod 10 on the railing body 1 is inserted into the groove 9 of the connecting member 5. At this time, the installation and disassembly of the railing body 1 are more convenient. When disassembling, it is only necessary to move the railing body 1 upward and disengage it from the groove 9 of the connecting member 5. When the railing body 1 is inserted into the groove 9 of the connecting member 5, the horizontal and vertical downward forces of the railing body 1 will be limited by the connecting plate 12, thereby ensuring the stability of the railing body 1. In addition, as an alternative embodiment, the connecting member 5 can be detachably connected to the railing body 1 by bolts.

[0038] like Figure 2 As shown, in this embodiment, the connecting member 5 is a columnar body extending vertically upward, specifically a cylindrical body. The bottom of the connecting member 5 is fixedly connected to the upper end surface of the connecting plate 12 by welding.

The fastener is a bolt, and the fastener is connected to the flange 4 after passing through the second fixing plate. At this time, the gravity of the railing body 1 is borne by the fastener and the first fixing plate. The first fixing plate and the second fixing plate are arranged perpendicularly to each other, and the structure is relatively simple and the installation is relatively convenient. In addition, as a replaceable embodiment, a reinforcing rib is arranged between the first fixing plate and the second fixing plate. In addition, as a replaceable embodiment, the fixing member 6 can be set as a rectangular block, and the fastener is connected to the flange 4 after passing through the fixing member 6 from the side end face of the fixing member 6.

[0040] Installation method of the installation device of the replaceable handrail: the upper end surface of the concrete flange 4 is provided with a connecting plate 12, and the lower end surface of the connecting plate 12 extends downward to two extension plates 7, and a sealing member 8 is provided between the extension plate 7 and the flange 4. The extension plates 7 are clamped on both sides of the flange 4 respectively, and after the screw passes through the extension plate 7, nuts are arranged at both ends of the screw for fixing. The second end surface 3 of the handrail body 1 is fixedly connected with the first fixing plate of the fixing member 6, and the second fixing plate of the fixing member 6 is attached to the outer end surface of the flange 4, and is connected to the flange 4 after passing through the second fixing plate with a bolt. During installation, the first fixing plate of the fixing member 6 is welded to the handrail body 1, and then the connecting plate 12 is installed to the upper end surface of the flange 4 through the screw, and the first end surface 2 of the handrail body 1 is aligned with the groove 9 on the connecting member 5 and inserted, and the bolt is passed through the second fastener to fix the handrail body 1 to the concrete flange 4 for fixing.
