[0025] The various embodiments of the present invention will be described in more detail below with reference to the drawings. In each of the drawings, the same elements are denoted by the same or similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.
[0026] As Figures 1 to 5As shown in the figure, the present application provides a spacer for controlling the concrete cover thickness, comprising: a support plate; at least two hooks 1, the two hooks 1 are respectively connected to both ends of the support plate, and each hook 1 is respectively provided with a hook groove 11, and the hook groove 11 is used for hanging on the horizontal steel bars of the steel bar support; a tail hook 2, connected to the middle of the support plate, the tail hook 2 and each hook 1 are arranged on the same side of the support plate, and the tail hook 2 is provided with a tail hook groove 21, and the opening direction of the tail hook groove 21 is perpendicular to that of the hook groove 11, and the tail hook groove is used for being clamped onto the vertical steel bars between the steel bars.
[0027] Wherein, the side surface of the hook groove 11 facing away from the tail hook 2 is used for supporting on the inner side surface of the casting formwork, so that a casting layer with a preset thickness is formed between the formwork and the steel bar support.
[0028] In this embodiment, the spacer for controlling the concrete cover thickness provided is designed according to the body structure of a "lobster". The hooks 1 on both sides of the support plate are directly hooked on the transverse steel bars (horizontal steel bars) of the steel bar support, and the tail hook 2 in the middle of the support plate is clamped on the longitudinal steel bars of the steel bar support through the tail hook groove 21. The two hooks 1 and one tail hook 2 form a triangular distribution fixing form, making the fixing of the spacer of the present application on the steel bar support more stable. The predetermined distances between the hook groove 11 and the tail hook groove 21 and the side surface of the support plate facing away from the tail hook 2 are the concrete cover thickness. During the process of concrete casting, the formwork is fixed on the side surface of the support plate facing away from the tail hook 2 (also called the outer side surface of the support plate), so that the formwork is attached to the support plate and the two hooks 1. Then, concrete is cast. The distance between the formwork and the steel bar support is the concrete cover thickness.
[0029] In this embodiment, the two hooks 1 are arranged in parallel, and the hook grooves 11 are arranged in the same direction. So that the two hooks 1 can be simultaneously hooked onto the same transverse steel bar, and at the same time, cooperate with the tail hook 2 in the middle of the support plate to form an isosceles triangle, making the fixing force of the spacer more uniform.
[0030] In an alternative embodiment of the present invention, as Figure 3 And Figure 5 shown, each hook 1 is provided with two threaded holes communicating with its respective hook groove 11, the two threaded holes are coaxial, and an adjustable bolt 3 is connected in each threaded hole. The adjustable bolt 3 is used for adjusting the preset distance between the steel bar support and the support plate support. It can be understood that, as Figure 5 shown, the function of the adjustable bolt 3 arranged on the Figure 5 right side in Figure 5The function of the adjustable bolt 3 on the left side is to cooperate with the adjustable bolt 3 on the right side to fix the transverse reinforcement so that the hook 1 is fixed to the transverse reinforcement.
[0031] In an optional embodiment of the present invention, a threaded hole is provided in the middle of the support plate, the threaded hole penetrates the support plate and communicates with the tail hook slot 21, and an adjustable bolt 3 is connected in the threaded hole, and the adjustable bolt 3 is used to adjust the preset distance between the tail hook slot 21 and the support plate. It can be understood that the adjustable bolt 3 at the tail hook 2 is used in conjunction with the adjustable bolt 3 at the hook 1, so as to make the thickness of the concrete protective layer consistent.
[0032] In an optional embodiment of the present invention, the screw heads of the adjustable bolts 3 are all "I"-shaped grooves or "X"-shaped grooves. In actual operation, the adjustable bolts 3 can be screwed by a screwdriver to change the thickness of the concrete cover.
[0033] It should be understood that each of the adjustable bolts 3 does not extend beyond the side of the support plate away from the tail hook 2. When the adjustable bolt 3 extends beyond the outer side of the support plate, the template cannot be attached to the outer side of the support plate, making it impossible to ensure the consistency of the thickness of the concrete cover.
[0034] In this embodiment, each of the hooks 1 and the tail hook 2 is welded to the support plate.
[0035] In an optional embodiment, the gasket for controlling the thickness of the concrete protective layer is a structural member formed by integral stamping. The integral stamping makes the structural forming simple, and processes such as processing threaded holes and installing adjustable bolts can be performed later.
[0036] The gasket for controlling the thickness of the concrete protective layer provided by the present application forms a triangular distribution connection form through the structural form of two hooks 1 and a tail hook 2, so that the gasket is fixed to the steel support more stably, and the support plate and the template are attached together and poured in the concrete, so that the surface of the concrete is more flush. The adjustable bolt 3 can adjust the thickness of the concrete protective layer, so that the gasket has better applicability.
[0037] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the said element.
[0038] Finally, it should be noted that: Obviously, the above embodiments are merely examples given for clearly illustrating the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
