Description

Technical Field

[0001] The utility model relates to the technical field of building cover plates, in particular to a sunken concrete cover plate handle structure. Background Art

[0002] In water conservancy and hydropower projects, cable trenches and drainage ditches are usually covered with covers according to operation and maintenance needs. The existing design usually does not consider the setting of handle solutions. Usually, multiple people are used to manually lift to remove the cover, and then clean or inspect the cable trench or drainage ditch and other structures. After completion, the cover is reset by multiple people. This mode of lifting is very inconvenient and can easily injure people or cause damage to the cover due to improper handling. The existing conventional design is to embed two hooks on the cover to facilitate handling. However, since the hooks are exposed on the cover, if pedestrians walk on the cover, they are very likely to fall due to the hooks. In order to overcome the current problems in the handling of reinforced concrete cover plates, a new handle design structure is proposed to comprehensively solve the current problems encountered in the handling of reinforced concrete cover plates.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0021] like Figure 1-4As shown, a sunken concrete cover handle structure is particularly suitable for water conservancy and hydropower projects that need to facilitate the removal of the upper cover when internal maintenance of structures such as drainage ditches and cable trenches is required. The concrete cover handle structure includes a cover 1 and a handle assembly 2. The cover 1 is provided with a concrete layer, and a groove 11 is provided on the top surface of the concrete layer of the cover 1. The handle assembly 2 includes a base 21 and a handle member 22. The base 21 is embedded in the groove 11 and cooperates with the groove 11. The top of the base 21 does not protrude from the top surface of the cover 1, and similarly, the bottom of the base 21 does not protrude from the bottom surface of the cover 1. It should be noted that the top surface of the cover 1 is the end surface facing the human side when installed on the corresponding structure; the base 21 has a cavity 210 inside, and the top of the base 21 is open, and the base 21 has a connecting portion 2101 and the non-connecting portion 2102, the handle piece 22 is located in the cavity 210, and the end of the handle piece 22 is fixedly connected to the connecting portion 2101, and the top of the handle piece 22 is at least partially flush with the top surface of the concrete layer of the cover plate 1 to avoid the handle piece 22 affecting the normal walking of pedestrians / staff, and the part where the top of the handle piece 22 is flush with the top surface of the concrete layer can provide a support point for the feet of pedestrians / staff; there is a spacing space between the inner wall of the cavity 210 and the non-connecting portion 2102, and the spacing space can facilitate the staff's hands to extend into the cavity 210, and of course it can also be convenient for lifting.

[0022] In this embodiment, the opening of the base 21 can be separated into a first opening and a second opening by the handle 22. Firstly, the existence of the first opening and the second opening can facilitate the insertion of the staff's hands and the insertion of the hook to move the cover 1 to the target position, thereby realizing the opening or closing of the drainage ditch, cable trench, etc.; secondly, the handle 22 can also reduce the size of the opening, further reducing or avoiding the possibility of pedestrians / staff being tripped due to the existence of the opening.

[0023] In this embodiment, the flush arrangement of the concrete cover plate 1 and the handle assembly 2 facilitates opening and closing of the concrete cover plate 1. The handle assembly 2, embedded in the cover plate 1, also effectively prevents wear, thereby extending the service life of the cover plate 1 and the handle assembly 2. In this embodiment, the base 21 includes a sleeve 211. The inner wall of the sleeve 211 has a first wall and a second wall. The first wall is the aforementioned connecting portion 2101, and the second wall is the aforementioned non-connecting portion 2102. The top surface of the sleeve 211 is at least partially flush with the top surface of the concrete layer to facilitate positioning of the handle 22 when it is installed and fixed within the base 21. The base 21 also includes a bottom plate 212, which is located below the sleeve 211 and is connected to the sleeve 211.

[0024] In this embodiment, the bottom plate 212 is provided with a drainage hole 23, and the cover plate 1 is provided with a through hole connected to the drainage hole 23. The through hole is preferably a vertical hole extending from top to bottom for ease of molding. The combination of the drainage hole 23 and the through hole ensures that water does not accumulate within the cavity 210 when the concrete cover plate does not need to be opened. At least one drainage hole 23 is provided, and the number of through holes is adjusted accordingly when two or more drainage holes 23 are provided.

[0025] In this embodiment, the base 21 can be a square steel tube with dimensions of 100 mm x 60 mm and a thickness of 5 mm. The handle 22 is preferably positioned in the center of the sleeve 211 and can be a round steel tube with a diameter of 16 mm. The weld between the base 21 and the handle 22 is a full weld. The diameter of the drain hole 23 can be 10 mm.

[0026] In this embodiment, anchor bars 3 are provided within the concrete layer of the cover plate 1 and are connected to the base plate 212. The anchor bars 3 are made of grade tertiary steel and are preferably located in the middle of the sleeve 211 and welded to the base plate 212. Four anchor bars 3 may be provided to effectively anchor the base 21 within the concrete layer of the cover plate 1.

[0027] In this embodiment, a pair of handle assemblies 2 are provided. In the longitudinal direction of the cover plate 1, the distance between the center of the handle assembly 2 and the outer wall of the cover plate 1 is H1, and the distance between the centers of adjacent handle assemblies 2 is H2. H2>H1 is satisfied, so that the handle assembly 2 is closer to the outer wall of the cover plate 1. In order to ensure balanced force and facilitate carrying, the two handle assemblies 2 are symmetrically distributed. The two handle assemblies 2 are located at two points of the fifth equal division in the longitudinal direction of the cover plate 1 (see FIG. Figure 1 ), that is, H1 is approximately equal to 3 times H2.

[0028] In this embodiment, in order to make the handle 22 capable of being hoisted and more convenient during hoisting, Figure 3 As shown, a bent section 221 is provided at the end of the handle 22 , and a fixed end connected to the connecting portion 2101 is provided on the bent section 221 , and the fixed end of the bent section 221 faces away from the top surface of the concrete layer.

[0029] The above embodiment is only a preferred technical solution of the present invention. Those skilled in the art should understand that the technical solutions or parameters in the embodiment can be modified or replaced without departing from the principle and essence of the present invention, and all should be included in the protection scope of the present invention.
