Description

Technical Field

[0001] This application relates to the technical field of protective railings for dam construction, and in particular to a simulated wood railing for the demolition of an original dam. Background Technology

[0002] In the field of water conservancy engineering construction and maintenance, the demolition of original dam structures is a common and complex task. Water conservancy facilities often require demolition due to long service life, structural aging, functional adjustments, or planning changes. For example, many medium and small-sized reservoir dams built in my country between the 1970s and 1990s face demolition due to various issues. In the demolition area, railings are necessary for safety. While traditional solid wood railings are thick, durable, and aesthetically pleasing, with a long lifespan and diverse textures, they are expensive, have poor waterproofing, are unsuitable for areas with large temperature differences, require regular maintenance, and are tedious to clean. Currently, wood-plastic composite railings are commonly used for safety protection.

[0003] Existing imitation wood railings require a large number of fastening bolts to connect various components during assembly. When using fastening bolts to connect the two ends of the handrail to the two posts, it is not possible to quickly position the handrail for installation, nor can it provide stable temporary support for the handrail. The handrail needs to be supported for a long time. Otherwise, when one end of the handrail is fixed, the other end will sag. This will cause the fastening bolts and the end of the handrail to be subjected to great pressure, which may lead to breakage or misalignment at the connection of the end of the wood-plastic composite handrail. Utility Model Content

[0004] The purpose of this application is to provide a simulated wood railing for the demolition of an original dam. This railing offers advantages such as rapid positioning of the handrail when installing it between two posts, and temporary support to prevent sagging and swaying that could affect precise installation. It solves the problems of existing simulated wood railings that require numerous bolts to connect components during assembly. When using bolts to connect the two ends of the handrail to the posts, it is difficult to quickly position the handrail and provide stable temporary support. Prolonged support is necessary, otherwise, the handrail may sag when one end is fixed, causing excessive pressure on the bolts and the handrail ends, potentially leading to breakage or misalignment at the joints.

[0005] This application provides a simulated wooden railing for the demolition of an original dam, employing the following technical solution: A simulated wooden railing for the demolition of an original dam includes a railing, comprising posts, handrails, and square tubes. The railing is assembled from the posts, handrails, and square tubes. Two handrails are provided between two adjacent posts, with the two handrails between two posts arranged vertically. Multiple square tubes are provided between the two vertically arranged handrails. Connecting sleeves are fixedly provided on the outer surface of the ends of the handrails, and the connecting sleeves are fixedly provided to the posts by fastening bolts. On one side, a positioning frame is fixedly installed on one side of the column corresponding to the position of the connecting sleeve. The top of the positioning frame is open. The connecting sleeve is inserted into the inner wall of the middle part of the positioning frame. On the opposite side of the two handrails distributed vertically, multiple connecting brackets are fixedly installed by fastening bolts. The inner walls of both ends of the square tube are slidably sleeved on the outer surfaces of the connecting brackets corresponding to the upper and lower handrails. A support member is installed at the bottom of the lower handrail. The support member includes a threaded sleeve. A support screw is connected to the inner wall of the middle part of the threaded sleeve.

[0006] By adopting the above technical solution, the matching arrangement of the connecting sleeve and the positioning frame enables rapid positioning of the handrail installation position when connecting the handrail to the column, eliminating the need for repeated adjustments. The threaded sleeve in the support component, in conjunction with the support screw, assists the positioning frame in providing stable temporary support for the handrail, avoiding the need to lift the handrail for extended periods and reducing installation difficulty. The sliding sleeve structure of the connecting frame and the square tube facilitates the rapid installation and disassembly of the square tube, improving the overall assembly efficiency of the railing. Furthermore, when installing the upper handrail, the square tube installed on the lower handrail can provide auxiliary support for the installation of the upper handrail.

[0007] Preferably, the inner wall of the middle part of the handrail is hollow, a reinforcing rib is fixedly provided on the inner wall of the middle part of the handrail, and the top corners of the handrail are rounded.

[0008] By adopting the above technical solutions, the hollow design of the handrail can reduce its own weight, making it easier to transport and install. The reinforcing ribs can enhance the structural strength of the handrail and ensure its load-bearing capacity. The rounded corners at the top of the handrail can prevent sharp edges from causing bumps and injuries to construction workers, thus improving safety.

[0009] Preferably, a buffer pad is provided between the connecting sleeve and the column, and a first mounting groove is provided on the side of the connecting sleeve near the column, and the buffer pad is fixedly disposed in the inner wall of the first mounting groove.

[0010] By adopting the above technical solution, the buffer pad can play a buffering role when the connecting sleeve is connected to the column, reducing the hard collision and friction between the two, avoiding damage to the surface of the component. The first mounting groove provides a stable installation position for the buffer pad, preventing the buffer pad from shifting or falling off during use, and ensuring the continuity of the buffering effect.

[0011] Preferably, the inner wall of the bottom end of the column is slidably sleeved on the outer surface of the middle part of the fixed plug rod, the column and the fixed plug rod are fixedly connected by fastening bolts, the bottom end of the fixed plug rod is fixedly set on the top of the fixed base plate, and the fixed base plate is fixedly set on the ground by expansion bolts.

[0012] By adopting the above technical solution, the combination of the fixed base plate and the expansion bolts can securely install the fixed rod on the ground, providing a reliable support foundation for the column and improving the stability of the column installation.

[0013] Preferably, the bottom end of the column is provided with a receiving groove for accommodating the expansion bolts on the fixed base plate, the bottom end of the column covers the expansion bolts on the fixed base plate, a sealing gasket is provided between the edge of the bottom end of the column and the fixed base plate, and a second mounting groove is provided at the bottom end of the column, with the sealing gasket fixedly disposed in the inner wall of the second mounting groove.

[0014] By adopting the above technical solution, the column can cover and hide the expansion bolts on the fixed base plate. The sealing gasket can enhance the sealing between the column and the fixed base plate, preventing rainwater, dust and other impurities from entering the joint gap and corroding the expansion bolts. It also prevents the expansion bolts from being affected by the corrosion of rainwater, dust and other impurities, thus preventing them from being disassembled. The second mounting groove provides a stable installation space for the sealing gasket, preventing the sealing gasket from shifting and ensuring that the sealing gasket can play an effective role.

[0015] Preferably, a limiting frame is fixedly provided on the inner wall of the middle part of the column, and the bottom outer surface of the limiting frame abuts against the top outer surface of the fixed insertion rod.

[0016] By adopting the above technical solution, the abutting fit between the limiting frame and the top of the fixed plug can limit the installation position of the column, so that the bolt connection holes between the column and the fixed plug can be precisely aligned, which facilitates the subsequent connection between the column and the fixed plug using fastening bolts.

[0017] Preferably, a protective cover is fitted on the top of the column, and a connecting rod is fixedly installed at the bottom of the inner side of the protective cover. The connecting rod is fixedly connected to the column by fastening bolts.

[0018] By adopting the above technical solution, the protective cover can seal the top opening of the column, preventing rainwater, debris and other objects from entering the column and causing corrosion or blockage of the components. The cooperation between the connecting rod and the fastening bolt ensures the stability of the connection between the protective cover and the column.

[0019] Preferably, the outer surface of the middle part of the threaded sleeve is engaged with the inner wall of the engagement bracket, and the engagement bracket is fixedly installed at the bottom of the handrail located below.

[0020] By adopting the above technical solution, the snap-fit ​​bracket can fix and store the threaded sleeve, making it convenient to transport and store the handrail, and preventing the threaded sleeve from swinging around and affecting the storage space when transporting the handrail.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This type of imitation wood railing for dam demolition construction, through the cooperation of the connecting sleeve and the positioning frame, can quickly position the handrail when connecting it to the column, without repeated adjustments. The threaded sleeve in the support component cooperates with the support screw to assist the positioning frame in providing stable temporary support for the handrail. This achieves quick positioning of the handrail when installing it between two columns and provides temporary support, preventing the handrail from sag and swinging, which would affect the accurate installation of the handrail.
