Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically a steel casing protective cover. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] In construction, manually excavated bored piles are often required. However, due to varying soil conditions in different regions, sidewall collapses can occur during excavation. Therefore, steel casings need to be installed on the inner walls of the bored piles to protect them and prevent collapse. Since the top and bottom of the steel casings are uncovered, and construction takes time, a protective cover needs to be installed on top of the casing to prevent personnel from falling in or debris from entering. This provides protection when no construction is underway. Furthermore, severe weather can also affect construction. Therefore, how to effectively protect the interior of the bored piles is a problem that needs to be solved.

[0004] The diameter of manually excavated bored piles varies in different construction processes, so finding a suitable method for using steel casings of different diameters is a problem to be solved. Furthermore, the different diameters of the steel casings affect the quality and stability of the protective covers, thus ensuring stable installation of the protective covers is another issue. During installation, the integrated design of the protective covers increases costs related to transportation, installation, and dismantling; therefore, making the installation of the protective covers convenient is yet another problem to be solved.

[0005] In summary, several issues need to be addressed: how to effectively protect the internal space of manually excavated bored piles to prevent people from falling in or debris from entering; how to ensure the stable installation, disassembly, and transportation of the protective cover; and how to make it suitable for use with steel casings of different diameters. Utility Model Content

[0006] The purpose of this invention is to provide a protective cover for steel casings. This device uses multiple support members arranged in a circumferential array at the top of the steel casing, allowing workers to access the casing during construction by disassembling only a few support members. The remaining protective members are positioned appropriately to protect workers inside the casing from falling debris. The height of the connecting parts is adjustable, allowing the device to disperse rain and snow in adverse weather conditions. The support members have a frame; the frames connect to the inside of the steel casing, preventing workers from falling when construction is not needed. The frame design also reduces the weight of the protective cover, making it easy to install and remove.

[0007] To achieve the above objectives, this utility model employs the following technical solution:

[0008] A protective cover for a steel casing includes support members and protective members. Multiple support members are arranged in a circumferential array at the top of the steel casing, with adjacent support members connected to each other. The bottom of each support member contacts the inner wall of the steel casing. Protective members are provided on each support member and connected to the top of the support member. The support members are arranged in a fan shape, with a connecting member at the center of each support member. The connecting member is threadedly connected to the support member. The connection between adjacent support members allows the support member to support the protective member. Furthermore, the bottom of the support member contacts the inner wall of the steel casing, preventing the support member from tilting and failing to provide adequate support. A frame is provided in the middle of the support member, reducing the overall weight and connecting adjacent support members through the frame. A threaded hole is provided at the center of the support member, where multiple frames connect, and the connecting member is connected to the support member through the threaded hole.

[0009] One end of the connector has a limiting member with an annular groove. The middle of the protective component connects to the annular groove of the connector. The top of the support component has a fixing member, and a protective component is placed between the fixing member and the support component to secure the protective component. Both ends of the connector connect to the protective component and the support component respectively. The bottom of the connector has threads and connects to the skeleton of the support component. This threaded connection allows the connector to move up and down, meaning the height of the limiting member on the connector is adjustable. This allows the protective component to have different tilt angles when connected to the support component, making it suitable for different weather conditions such as rain and snow. The limiting member on the connector has an annular groove, allowing the protective component to move along the groove and extend to its maximum position before connecting with the connector to protect the inside of the steel casing. Multiple support components contact the top surface and inner wall of the steel casing and are connected and supported at one end of the steel casing. Corresponding protective components are also provided on the support components.

[0010] The connector and the support are connected by a threaded connection to the skeleton in the middle. The height of the limiting member on the connector is adjustable. The protective member rotates around the limiting member via an annular groove, and adjacent protective members are connected. The limiting member on the connector is positioned on the connector and is engaged with the connector. The protective member is made of a flexible material, such as rubber or a polymer, allowing it to expand and contract and protect the interior of the steel casing. The edge of the protective member connects to the edge of the support, adjacent protective members connect, and the middle of the protective member is connected to the support via a connector. Multiple protective members are combined into a conical shape on the upper part of the support. The other end of the protective member contacts the upper surface of the support, and the top of the support has a fixing member. The fixing member, through compression and fixation with the support, limits the protective member, ensuring that the other end of the protective member is fixed to the upper surface of the support, thereby protecting the internal space of the steel casing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This device uses multiple support members arranged in a circular array at the top of the steel casing. This allows workers to access the casing and perform construction work by disassembling only a few support members. The remaining protective components are strategically positioned to protect workers inside the casing from falling debris. The height of the connecting parts is adjustable, allowing the device to disperse rain and snow in adverse weather conditions. The support members have a frame that connects to the inside of the casing, preventing workers from falling when construction is not underway. The frame design also reduces the weight of the protective cover, facilitating its installation and removal. Attached Figure Description

[0019] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0020] This utility model describes a protective cover for a steel casing. The main structure includes a support member 1, a protective member 2, and a connecting member 3. The support members 1 are arranged in a fan shape, with multiple support members 1 positioned on the top of the steel casing and distributed circumferentially at the outlet, allowing the protective member 2 to protect the interior of the steel casing. Adjacent support members 1 are connected to each other, enabling the support member 1 to support the protective member 2. The bottom of the support member 1 contacts the inner wall of the steel casing, preventing the support member 1 from tilting and failing to provide adequate support. A frame 7 is provided in the middle of the support member 1, reducing the overall weight and connecting adjacent support members 1 through the frame 7. A threaded hole is provided at the center of the support member 1, where multiple frames 7 connect, and the connecting member 3 is connected to the support member 1 through the threaded hole. Multiple support members 1 are combined to form a stepped ring (as shown in the attached drawing). Figure 2 As shown in the diagram, multiple support members 1 are in contact with the top surface and inner wall of the steel casing and are connected and supported at one end of the steel casing. Protective members 2 are also provided on the support members 1. The protective members 2 are made of flexible materials, such as rubber or polymers, allowing them to expand and contract and protect the interior of the steel casing. The edges of the protective members 2 are connected to the edges of the support members 1, adjacent protective members 2 are connected, and the middle of the protective members 2 is connected to the support members 1 via connecting members 3. This allows the multiple protective members 2 to be arranged in a conical shape on the upper part of the support members 1.

[0021] The two ends of the connector 3 are connected to the protective component 2 and the support component 1, respectively. The bottom of the connector 3 is threaded and threadedly connected to the skeleton 7 of the support component 1. The threaded connection allows the connector 3 to move up and down, meaning the height of the limiting component 4 on the connector 3 is adjustable. This allows the protective component 2 to have different tilt angles when connected to the support component 1, making it suitable for different weather conditions such as rain and snow. The limiting component 4 on the connector 3 has an annular groove 5, allowing the protective component 2 to move along the annular groove 5, extending to its maximum position and connecting with the connector 3 to protect the inside of the steel casing. Furthermore, the limiting component 4 is positioned on the connector 3, meaning that when the connector 3 is threadedly connected to the skeleton 7 on the support component 1 by rotation, the direction of the limiting component 4 does not change with the rotation of the connector 3, allowing the limiting component 4 to better adapt to the connection of the protective component 2. Furthermore, a limiting groove is provided on one end face of the limiting member 4, allowing the connecting member 3 to be engaged within the limiting member 4. The limiting member 4 and the connecting member 3 can rotate relative to each other. A baffle 8 is provided on one end face of the limiting member 4, which connects to the limiting member 4, limiting the support member 1 and sealing one end of the annular groove 5. The limiting member 4 is integrally cast, allowing one end of the protective member 2 to move within the annular groove 5 formed by the baffle 8 and the limiting member 4, and the rotation of the connecting member 3 does not affect the direction of the limiting member 4.

[0022] The other end of the protective component 2 contacts the upper surface of the support component 1. The top of the support component 1 is equipped with a fixing component 6. Through the compression and fixing of the fixing component 6 with the support component 1, the protective component 2 is limited, allowing the other end of the protective component 2 to be fixed to the upper surface of the support component 1, thereby protecting the internal space of the steel casing. Furthermore, due to the height adjustment of the connecting component 3, the compression and fixing position of the protective component 2 is not the same. Adjacent protective components 2 are connected on both sides, allowing multiple protective components 2 to protect the steel casing and prevent rain, snow, foreign objects, etc., from falling in.

[0023] Detailed instructions for use:

[0024] Multiple support components 1 are arranged in a circumferential array at the top of the steel casing, and connecting components 3 and limiting components 4 are sequentially connected to the upper surface of the support components 1. In daily use, the bottom of the limiting component 4 on the connecting component 3 contacts the frame 7 on the support component 1, causing the protective component 2 to contact the upper surface of the support component 1, i.e., in a horizontal state, facilitating the disassembly of various components. In rainy or snowy weather, to facilitate the dissipation of rain and snow and prevent localized depressions, the connecting component 3 is moved upwards, making the protective component 2 conical in shape, allowing rain and snow to fall in all directions. Furthermore, the protective component 2 is made of flexible material, which helps prevent debris from falling in, thus ensuring a safe working environment inside the casing.

[0025] For construction workers, to facilitate their entry and removal of the protective cover, only a few adjacent support components 1 need to be removed during construction, allowing workers to enter normally without having to completely remove the protective cover from the steel casing. The entire removal process is convenient, and since the protective cover is not completely removed, it also helps prevent foreign objects from falling into the steel casing during construction. Furthermore, workers working under the protective component 2 can avoid being injured by falling debris.

[0026] In summary, this device uses multiple support members 1 arranged in a circular array at the top of the steel casing. This allows workers to access the casing and perform construction work by disassembling only a few support members 1. The remaining protective members 2 are positioned appropriately to protect workers inside the casing from falling debris. The height of the connecting members 3 is adjustable, allowing the device to disperse rain and snow in adverse weather conditions. The support members 1 are equipped with frames 7, which connect to the interior of the steel casing, preventing workers from falling when construction is not required. The frames 7 also reduce the weight of the protective cover, facilitating its installation and removal.
