TECHNICAL FIELD
[0001] The utility model relates to the technical field of building, specifically relates to a concrete cushion block that can adapt to different reinforcing steel bar diameters and cover thicknesses. BACKGROUND
[0002] In recent years, with the vigorous development of the construction industry, reinforced concrete pouring technology has played a crucial role in the industry. However, in actual construction processes, the problem of exposed reinforcing steel bars has always been a difficult issue that needs attention. When reinforcing steel bars are exposed to air and water for a long time, they are prone to rust, which not only reduces the strength of reinforced concrete but also may affect the safety and durability of the entire building structure.
[0003] To solve this problem, a protective layer is usually set between the reinforcing steel bars and the concrete to prevent the reinforcing steel bars from directly contacting the external environment. The main function of this protective layer is to slow down the corrosion rate of the reinforcing steel bars, thereby prolonging the service life of the concrete structure. However, the thickness of the protective layer is not randomly set but needs to be reasonably adjusted according to the diameter of the reinforcing steel bars. If the protective layer is too thin, it may not provide sufficient protection for the reinforcing steel bars, leading to easy rusting of the reinforcing steel bars and thus reducing the structural strength; if the protective layer is too thick, it may damage the durability of the concrete and cause space waste.
[0004] In actual construction, cushion blocks are often used to adjust the thickness of the reinforcing steel bar protective layer. However, the commonly used cushion blocks on the market have some problems. First, these cushion blocks have relatively single functions and can only be used for reinforcing steel bars of specific diameters, and cannot be well adapted to reinforcing steel bars of different diameters. This leads to the need to prepare multiple different specifications of cushion blocks in actual construction processes, thereby increasing construction costs and complexity.
[0005] Secondly, the heights of these cushion blocks are relatively consistent and cannot be adjusted according to the actual needs of the protective layer. Since the thickness of the protective layer needs to be determined according to the diameter of the reinforcing steel bar, the thickness of the protective layer required for reinforcing steel bars of different diameters is also different. However, existing cushion blocks often cannot provide such flexibility, making it difficult to accurately control the thickness of the protective layer in actual construction. SUMMARY

[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely below, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts belong to the protection scope of the utility model.
[0026] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model.
[0027] In the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, can be fixed connection, can also be detachable connection, or integrated; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements or the interaction relationship of two elements. For the person skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0028] In the present utility model, unless otherwise expressly provided and limited, the first feature is "on" or "under" the second feature, which can be direct contact of the first and second features, or indirect contact of the first and second features through an intermediate medium. Moreover, the first feature "above", "above" and "above" the second feature can be directly above or obliquely above the second feature, or only indicate that the first feature is higher than the second feature in horizontal height. The first feature "below", "below" and "below" the second feature can be directly below or obliquely below the second feature, or only indicate that the first feature is lower than the second feature in horizontal height.
[0029] As shown in Figures 1-8 A concrete pad capable of adapting to different steel bar diameters and protective layer thicknesses, comprising a support seat 1 and a base 2 for keeping the support seat 1 in an upright state in use, the base 2 is recessed with a guide groove opening upward, the support seat 1 is vertically sleeved with the guide groove for guiding cooperation, and the support seat 1 is provided with a semicircular groove 3 for positioning steel bars. A plurality of sliding grooves 4 are symmetrically and vertically arranged on the peripheral wall of the base 2, a plurality of latches 5 are arranged at the bottom of the support seat 1 corresponding to the positions of the sliding grooves 4, and the latches 5 and the sliding grooves 4 are guided and inserted for cooperation when the support seat 1 and the base 2 are assembled. The bottom of the support seat 1 is provided with a spring 6, and the lower end of the spring 6 abuts against the bottom of the guide groove of the base 2 when the support seat 1 and the base 2 are assembled.
[0030] When assembled, first, the latches 5 at the bottom of the support seat 1 are aligned with the sliding grooves 4 on the peripheral wall of the base 2. Since the sliding grooves 4 are vertically arranged and matched with the shape of the latches 5, the latches 5 can be smoothly inserted along the sliding grooves 4 to realize the preliminary connection of the support seat 1 and the base 2. After the latches 5 are completely inserted into the sliding grooves 4, the bottom of the support seat 1 will be sleeved with the guide groove of the base 2. At this time, the spring 6 is located between the support seat 1 and the base 2, and the lower end thereof abuts against the bottom of the guide groove. The elastic force of the spring 6 pushes the support seat 1 upward, so that the latches 5 maintain a certain tension in the sliding grooves 4, thereby ensuring the stability of the support seat 1 in the vertical direction.
[0031] The support seat 1 is provided with semicircular grooves 3, which can accommodate steel bars of different diameters. When it is necessary to position the steel bars on the pad, the steel bars can be placed in the semicircular grooves 3 matched with their diameters. Since the semicircular grooves 3 have a certain width range, they can adapt to steel bars of various diameters without the need to replace different specifications of pads.
[0032] By adjusting the position of the support base 1 in the guide groove, the relative height between the support base 1 and the base 2 can be changed, so as to adjust the thickness of the protective layer. Specifically, the support base 1 can be moved up and down along the sliding groove 4, so that the plug 5 slides in the sliding groove 4. Due to the elastic force of the spring 6, the support base 1 can maintain stability during movement, and can be stopped at any position as needed. In this way, the height of the support base 1 can be accurately adjusted according to the diameter of the steel bar and the required thickness of the protective layer. It is worth mentioning that the height of the support base can also be changed by replacing springs 6 with different elastic coefficients.
[0033] Specifically, as shown in the figure, the sliding groove 4 is a cylindrical structure, and the plug 5 is correspondingly provided as a cylindrical structure, and the number of the sliding groove 4 and the plug 5 is four.
[0034] Specifically, as shown in the figure, the guide groove is a cross-shaped structure, and the number of the semicircular groove 3 is two, and the two semicircular grooves 3 are perpendicular to each other to form a cross-shaped structure.
[0035] The utility model provides a concrete cushion block can adapt to different steel bar diameter and protective layer thickness, through the vertical sleeve joint guide cooperation of the guide groove of base and support base, and the semicircular groove on the support base realizes the positioning of the steel bar. In addition, the sliding groove of base and the plug guide of support base enhance the stability of the plug guide, and the setting of spring provides the buffer and adaptability. This design not only has the simple structure, the practicality is strong, and can effectively adapt to different size steel bar and protective layer thickness, improves the construction efficiency and the universality of cushion block.
[0036] The above only for the preferred embodiment of the utility model has been described, and does not limit the utility model, and any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
[0037] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that can be understood by those skilled in the art.
