Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, specifically to a concealed wrought iron fence connection device. Background Technology

[0002] Wrought iron fences are iron or steel enclosures constructed through artistic design, serving purposes of isolation, protection, and decoration. They are primarily used in residential areas, highways, commercial districts, and public spaces for the protection of personal safety and equipment, and their application is quite widespread. Conventionally, wrought iron fences are typically constructed with brick or concrete pillars at intervals, and the ends or bottom are fixed with embedded parts. These embedded parts act as fixed supports. However, in the face of foundation displacement and temperature stress, they cannot effectively synchronize deformation, and the connection points of the wrought iron fence are prone to breakage. Furthermore, the exposed connection points are susceptible to corrosion. Summary of the Invention

[0003] This invention addresses the problems of easy breakage and corrosion of connection nodes in existing wrought iron fences due to temperature or displacement deformation. It provides a concealed wrought iron fence connection device that employs a non-fixed connection method, allowing the horizontal bars of the wrought iron fence to move horizontally. This effectively avoids the risk of breakage due to temperature or displacement deformation and also prevents corrosion, thus improving the quality of the wrought iron fence.

[0004] To achieve the above objectives, the technical solution of this utility model is: a concealed wrought iron fence connection device, comprising two wall posts and horizontal bars spaced apart between the two wall posts. Each horizontal bar is a hollow, open-end rod-shaped structure, and each end of the horizontal bar is equipped with a connecting component for connection to the wall post. The connecting components installed at the ends of the horizontal bars effectively prevent the connection nodes from breaking or corroding.

[0005] The connecting assembly includes a shield and two L-shaped corner brackets. The two L-shaped corner brackets are arranged opposite each other, with the vertical portion of the L-shaped corner bracket inserted into the horizontal bar. A gap exists between the vertical portion of the L-shaped corner bracket and the inner side of the horizontal bar. The horizontal portion of the L-shaped corner bracket connects to the wall post. By inserting the vertical portion of the L-shaped corner bracket into the horizontal bar, the horizontal bar can be horizontally displaced, thereby reducing the risk of the wrought iron fence breaking due to temperature or displacement deformation. The L-shaped corner bracket provides support for the horizontal bar, achieving the effect of installing the horizontal bar between two wall posts.

[0006] The crossbar is fitted into the square hole of the shield, which gradually increases in size towards the wall column. The horizontal part of the L-shaped angle bracket is located inside the shield. The shield protects the connecting components, which are concealed within it, effectively preventing corrosion.

[0007] Furthermore, the length of the crossbar is less than the distance between the two wall columns, and there is a gap between the end of the crossbar and the inner side of the wall column. This is to ensure that the crossbar can be installed between the two wall columns and that the crossbar can be moved horizontally.

[0008] Furthermore, the horizontal portion of the L-shaped corner bracket has a fixing hole, and a chemical anchor bolt for fixing the horizontal portion of the L-shaped corner bracket is installed in the fixing hole. The L-shaped corner bracket is fixed to the inside of the wall column by the chemical anchor bolt, so that the L-shaped corner bracket can support and support the horizontal bar.

[0009] Furthermore, an I-beam connecting plate is provided between the vertical portions of the two opposing L-shaped corner brackets, and both ends of the I-beam connecting plate are detachably connected to the two L-shaped corner brackets respectively. The I-beam connecting plate serves to connect the two L-shaped corner brackets, improving the overall stability of the connecting assembly.

[0010] Furthermore, a strip groove is formed at the top of the vertical part of the L-shaped corner bracket, and a strip opening communicating with the strip groove is formed on the outer side of the vertical part of the L-shaped corner bracket. The end of the I-beam connecting plate is inserted into the strip groove. By inserting the end of the I-beam connecting plate into the strip groove, a detachable connection between the I-beam connecting plate and the L-shaped corner bracket is achieved.

[0011] Furthermore, the gap between the end of the shield and the wall column is filled with sealant.

[0012] The beneficial effects of this utility model through the above technical solution are as follows: This utility model has a reasonable structure and good performance. It adopts a non-fixed connection method, which allows the horizontal bars of the wrought iron railing to move horizontally. This can effectively avoid the risk of breakage due to temperature or displacement deformation, and can also effectively prevent rust, thus improving the quality of the wrought iron fence.

[0013] The L-shaped corner bracket of this utility model is fixed horizontally to the wall column and vertically inserted into the horizontal bar to support the horizontal bar. Since there are gaps between the end of the horizontal bar and the wall column, and between the vertical part of the L-shaped corner bracket and the horizontal bar, the horizontal bar of the wrought iron railing can be horizontally displaced, thereby reducing the risk of breakage due to temperature or displacement deformation.

[0014] This invention conceals the L-shaped corner bracket, I-beam connecting plate, and chemical anchor bolts of the connecting components by fitting a shielding cover over the end of the crossbar. The shielding cover covers and shields the connecting components, thereby preventing corrosion, enhancing durability, and extending service life. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 11As shown, a concealed wrought iron fence connection device includes two wall posts 1 and horizontal bars 2 spaced apart between the two wall posts 1. The horizontal bars 2 are hollow rod-shaped structures with open ends. Each end of the horizontal bar 2 is equipped with a connecting component for connection to the wall posts 1. In this embodiment, the distance between the two wall posts 1 is 330 mm, the width of the wall posts 1 is 37 mm, and the net distance between the two wall posts 1 is 293 mm. The horizontal bars 2 are made of 40 mm * 40 mm * 2.0 mm square steel tubing and are 288 mm long. The open ends of the horizontal bars 2 facilitate the installation of the connecting components, preventing breakage and corrosion.

[0018] The connecting assembly includes a shield 6 and two L-shaped corner brackets 3, which are arranged opposite each other. The vertical part of the L-shaped corner bracket 3 is inserted into the horizontal bar 2, and there is a gap between the vertical part of the L-shaped corner bracket 3 and the inner side of the horizontal bar 2. The horizontal part of the L-shaped corner bracket 3 is connected to the wall column 1. In this embodiment, the vertical part of the L-shaped corner bracket 3 is 60mm long and 20mm wide, and the horizontal part of the L-shaped corner bracket 3 is 30mm long and 20mm wide, and both are 3mm thick. The vertical part of the L-shaped corner bracket 3 is inserted into the horizontal bar 2 to support and support the horizontal bar 2. There is a gap between the vertical part of the L-shaped corner bracket 3 and the inner side of the horizontal bar 2 so that the horizontal bar 2 can move horizontally. When the wrought iron railing deforms due to temperature or displacement, the horizontal bar 2 of the wrought iron railing can adaptively move horizontally, thereby avoiding breakage. The design structure of the two L-shaped corner brackets 3 being arranged opposite each other ensures that the horizontal part of the L-shaped corner bracket 3 is located outside the crossbar 2, making it easy to fix the L-shaped corner bracket 3 to the inside of the wall column 1.

[0019] The crossbar 2 is fitted into the square hole of the shield 6, and the square hole of the shield 6 gradually increases in size towards the wall column 1. The horizontal part of the L-shaped corner bracket 3 is located inside the shield 6. In this embodiment, the front end of the shield 6 is frustum-shaped and the rear end is prism-shaped, with its small end facing inward and its large end facing outward. It is made of plastic.

[0020] The length of the horizontal bar 2 is less than the distance between the two wall posts 1, and there is a gap between the end of the horizontal bar 2 and the inner side of the wall post 1. The purpose is to ensure that the horizontal bar 2 of the wrought iron railing can adaptively move horizontally when the wrought iron railing deforms due to temperature or displacement, thereby avoiding the phenomenon of breakage.

[0021] The horizontal portion of the L-shaped corner bracket 3 has a fixing hole 4, and a chemical anchor 5 for fixing the horizontal portion of the L-shaped corner bracket 3 is installed in the fixing hole 4. In this embodiment, the horizontal portion of the L-shaped corner bracket 3 is fixed to the inside of the wall column 1 by the chemical anchor 5, so that the vertical portion of the L-shaped corner bracket 3 supports the horizontal bar 2.

[0022] An I-beam connecting plate 9 is provided between the vertical portions of the two opposing L-shaped corner brackets 3. The two ends of the I-beam connecting plate 9 are detachably connected to the two L-shaped corner brackets 3. In this embodiment, the I-beam connecting plate 9 connects the two opposing L-shaped corner brackets 3, providing a stable and reinforced connection and improving the overall stability of the connection assembly.

[0023] The top of the vertical part of the L-shaped corner bracket 3 is provided with a strip groove 7, and the outer side of the vertical part of the L-shaped corner bracket 3 is provided with a strip opening 8 that communicates with the strip groove 7. The end of the I-beam connecting plate 9 is inserted into the strip groove 7. In this embodiment, the strip groove 7 and the strip opening 8 facilitate the assembly and disassembly of the L-shaped corner bracket 3 and the I-beam connecting plate 9.

[0024] The gap between the end of the shield 6 and the wall column 1 is filled with sealant. In this embodiment, the sealant fills the gap between the shield 6 and the wall column 1, serving both a sealing and waterproofing function.

[0025] In use, this utility model first installs shielding covers 6 on both ends of the horizontal bar 2 and prepares two L-shaped corner brackets 3. Then, an I-beam connecting plate 9 is installed between the two L-shaped corner brackets 3 to connect the two L-shaped corner brackets 3. The two end plates of the I-beam connecting plate 9 are inserted into the strip grooves 7 from the ends of the vertical parts of the two L-shaped corner brackets 3. Then, the vertical parts of the two L-shaped corner brackets 3 are inserted into the horizontal bar 2, and the horizontal parts of the L-shaped corner brackets 3 are fixed to the inside of the wall column 1 by chemical anchors 5. Finally, the shielding covers 6 are moved so that they cover the ends of the horizontal bar 2, the L-shaped corner brackets 3 and the chemical anchors 5. The gap between the end of the shielding cover 6 and the wall column 1 is filled with sealant to complete the connection between the horizontal bar 2 and the wall column 1.
