Description

Technical Field

[0001] This utility model relates to the field of building construction. More specifically, this utility model relates to a stair corner protector and a stair tread structure. Background Technology

[0002] Traditional stair corner protectors commonly use materials such as glass strips, round steel, and angle iron. When glass strips are used, they are easily damaged during use, affecting the effectiveness of the corner protector and leading to frequent repairs. Angle steel corner protectors are relatively expensive, increasing construction costs. Traditional round steel corner protectors are difficult to secure, resulting in low construction efficiency and inconsistent quality of the stair tread surface; furthermore, the treads are prone to corner detachment during use. Therefore, it is necessary to design a stair corner protector structure that improves construction quality and reduces the risk of future repairs, addressing the problems associated with traditional glass, round steel, and angle steel materials. Utility Model Content

[0003] The purpose of this utility model is to provide a stair corner protector and a stair tread structure using it, in order to solve the problems of easy damage and repair during the use of glass stair corner protectors, the high cost of angle steel stair corner protectors, and the difficulties in construction and fixing of round steel stair corner protectors, as well as the risk of subsequent detachment.

[0004] To achieve these objectives and other advantages according to the present invention, a stair corner protector is provided, comprising:

[0005] Main rod;

[0006] Multiple first auxiliary poles are spaced apart on the main pole, and each of the first auxiliary poles is provided with a pre-embedded connector;

[0007] Multiple secondary poles are spaced apart on the main pole.

[0008] Furthermore, in the aforementioned stair corner protector, the pre-embedded connector has an extension on the side near the second auxiliary rod.

[0009] Furthermore, in the aforementioned stair corner protector, a screw is vertically provided on the embedded connector, and a threaded hole corresponding to the screw is provided on the extension portion, and the extension portion is connected to the embedded connector through the screw.

[0010] Furthermore, in the aforementioned stair corner protector, the first auxiliary rod is welded to the pre-embedded connector.

[0011] Furthermore, in the aforementioned stair corner protector, the main rod is a round steel bar.

[0012] Furthermore, in the aforementioned stair corner protector, both the first and second auxiliary rods are steel bars and are welded to the main rod.

[0013] Furthermore, in the aforementioned stair corner protector, multiple first auxiliary rods are evenly distributed on the main rod.

[0014] Furthermore, in the aforementioned stair corner protector, the number of the second auxiliary rods is equal to that of the first auxiliary rods, and they correspond one-to-one. The second auxiliary rods are perpendicular to the corresponding first auxiliary rods.

[0015] Furthermore, in the aforementioned stair corner protector, the upper end of the pre-embedded connector is provided with a positioning groove corresponding to the first auxiliary rod.

[0016] This utility model also provides a stair tread structure, including stair treads, on which the aforementioned stair corner protectors are provided.

[0017] The beneficial effects of this utility model are:

[0018] In this utility model of stair corner protectors, multiple pre-embedded connectors are used. During the initial prefabrication of the staircase, these connectors are pre-embedded into the treads of the stair steps according to the distance between the first auxiliary rods. During subsequent installation of the stair corner protectors, the first auxiliary rods are fixed to the corresponding pre-embedded connectors by spot welding, followed by the construction of the stair tread flooring. The application of this utility model of stair corner protectors in the stair tread structure effectively solves the problem of difficulty in fixing existing round steel stair corner protectors during construction. It facilitates construction while reducing the need for subsequent tread use, significantly lowering the risk of later repairs.

[0027] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it based on the description.

[0028] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] like Figures 1-2 As shown, an embodiment of this utility model provides a stair corner protector, comprising:

[0030] Main rod 1;

[0031] Multiple first auxiliary rods 2 are spaced apart on the main rod 1, and each of the first auxiliary rods 2 is provided with a pre-embedded connector 4;

[0032] Multiple secondary rods 3 are spaced apart on the main rod 1.

[0033] In this embodiment, multiple first auxiliary rods 2 are located on the same horizontal plane, forming a first mounting surface corresponding to the top surface of the step. Multiple second auxiliary rods 3 are located on the same horizontal plane, forming a second mounting surface corresponding to the top surface of the step. The included angle between the first mounting surface and the second mounting surface is no greater than 90°. In this embodiment, the main rod 1, the first auxiliary rod 2, and the second auxiliary rod 3 are machined as a whole. The main rod 1 is made of round steel, and the first auxiliary rods 2 and 3 are both made of steel wire. The stair corner protector is installed before the stair tread 5. The pre-embedded connector 4 below the first mounting surface is pre-embedded in the concrete structure of the stair tread 5, and the upper end of the pre-embedded connector 4 protrudes from the stair tread 5. When installing the stair corner protector, the first auxiliary rod 2 is connected to the pre-embedded connector 4. The first mounting surface and the second mounting surface are respectively embedded in the plaster layer of the top surface and the vertical surface of the step. In this embodiment, the first secondary rod 2 is fixed by the pre-embedded connector 4 of the stair corner protector, and the stair corner protector is fixed on the stair tread 5. In this way, when the first secondary rod 2 is made of round steel, the main rod 1 is fixed by the connector, which can effectively solve the problem of the difficulty in fixing the traditional round steel corner protector during construction. This ensures that the stair corner protector will not fall off during subsequent construction and use, which facilitates construction and also reduces the risk of subsequent damage and repair of the external corner.

[0034] Furthermore, in the aforementioned stair corner protector, the pre-embedded connector 4 has an extension 41 on the side near the second auxiliary rod 3.

[0035] In this embodiment, an extension 41 is provided on the lower end of the pre-embedded connector 4, and the extension 41 is arranged perpendicularly to the pre-embedded connector 4. The extension 41 is completely embedded in the stair tread 5, and its position relative to the stair tread 5 is stable, which can fix the pre-embedded connector 4 and prevent the pre-embedded connector 4 from shifting in the horizontal direction when it is pre-embedded in the stair tread 5.

[0036] Furthermore, in the aforementioned stair corner protector, a screw 43 is vertically provided on the pre-embedded connector 4, and a threaded hole corresponding to the screw 43 is provided on the extension 41. The extension 41 is connected to the pre-embedded connector 43 through the screw.

[0037] In this embodiment, the screw 43 is inserted into the threaded hole on the extension 41, allowing the screw 43 and the extension 41 to rotate relative to each other, thus connecting the screw 43 and the extension 41 together. The extension 41 is detachably connected to the pre-embedded connector 4 via the screw 43. Various extensions 41 of different lengths can be provided. For stair treads with different step heights, different lengths of extensions 41 are used to avoid conflicts between the extension 41 and the position of the reinforcing steel structure within the stair tread.

[0038] Furthermore, in the aforementioned stair corner protector, the first auxiliary rod 2 is welded to the pre-embedded connector 4.

[0039] In this embodiment, the pre-embedded connector 4 is embedded in the concrete structure of the stair tread 5, with the upper end of the pre-embedded connector 4 exposed. When the first auxiliary rod 2 is connected to the pre-embedded connector 4, welding is used to ensure the stability of the connection between the first auxiliary rod 2 and the pre-embedded connector 4.

[0040] Furthermore, in the aforementioned stair corner protector, both the first auxiliary rod 2 and the second auxiliary rod 3 are welded to the main rod 1.

[0041] In this embodiment, the first auxiliary rod 2 and the second auxiliary rod 3 are both welded to the main rod 1. The main rod 1, the first auxiliary rod 2 and the second auxiliary rod 3 can be pre-processed as a whole, and the first auxiliary rod 2 is then welded to the pre-embedded connector 4 during installation.

[0042] Furthermore, in the aforementioned stair corner protector, multiple first auxiliary rods 2 are evenly distributed on the main rod 1.

[0043] In this embodiment, multiple first auxiliary rods 2 are evenly distributed on the main rod 1, so that the main rod 1 is subjected to uniform force and can be stably fixed on the stair treads 5.

[0044] Furthermore, in the aforementioned stair corner protector, the number of the second auxiliary rod 3 and the number of the first auxiliary rod 2 are equal and correspond one-to-one, and the second auxiliary rod 3 and the corresponding first auxiliary rod 2 are perpendicular to each other.

[0045] In this embodiment, the second auxiliary rod 3 is perpendicular to the corresponding first auxiliary rod 2, and the two are in a claw shape, which can better fix it on the stair tread 5.

[0046] Furthermore, in the aforementioned stair corner protector, such as Figure 4 As shown, the upper end of the pre-embedded connector 4 is provided with a positioning groove 42 corresponding to the first auxiliary rod 2.

[0047] In this embodiment, in order to facilitate the positioning between the first auxiliary rods 2 of the pre-embedded connector 4, a positioning groove 42 is provided at the upper end of the pre-embedded connector 4. The first auxiliary rod 2 passes through the positioning groove 42 and its lower end is embedded in the positioning groove 42. After the positioning of the first auxiliary rod 2 and the pre-embedded connector 4 is achieved, the two are then welded together.

[0048] like Figure 3 As shown, this utility model also provides a stair tread structure, including stair tread 5, on which the aforementioned stair corner guards are provided.

[0049] In this embodiment, during the construction of the stair tread structure, multiple pre-embedded connectors 4 are pre-embedded on the top surface of the stair tread 5 during the concrete construction process. The upper ends of the pre-embedded connectors 4 are exposed in the concrete structure. After the concrete of the stair tread 5 is completed, the stair corner protectors are installed later. The main rod 1, the first auxiliary rod 2, and the second auxiliary rod 3 are pre-processed as a whole and installed on the stair tread 5. The multiple first auxiliary rods 2 correspond one-to-one with the multiple pre-embedded connectors 4. Then, the first auxiliary rods 2 are welded to the corresponding pre-embedded connectors 4 to complete the fixation of the stair corner protectors on the stair tread structure. Finally, the stair tread 5 is plastered, and the first and second auxiliary rods are embedded in the plaster layer on the top and vertical surfaces of the tread, respectively.

[0050] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
