[0002] During the construction of reinforced concrete structures in construction projects, controlling the thickness of the protective layer has always been a major problem in the construction process. When the steel bar protective layer is too thin, cracks caused by bonding slip around the steel bar can easily develop to the surface of the component, forming cracks along the longitudinal steel bar, causing the protective layer concrete to split and break, resulting in the strength of the steel bar not being able to fully play its role, and the splitting cracks pose a serious threat to the corrosion of the steel bar, which will directly affect the durability of the structure; when the steel bar protective layer is too thick, in addition to the easy appearance of large shrinkage cracks and temperature cracks on the surface of the component, it will directly weaken the bearing capacity of the component at the least, and even cause a major quality accident at the worst.

[0003] At present, the method of controlling the thickness of the steel bar protective layer in the construction industry is to use finished pads for protective layer control. However, due to the lack of connection between the finished pads and the formwork, they are prone to shifting during the pouring of concrete, which in turn causes the steel bars to shift, thereby affecting the thickness of the steel bar protective layer of the concrete component.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] An embodiment of the present application provides a steel bar protective layer thickness control structure, including a pad block 100, which is used to be arranged between the steel bar 20 and the template 30, and a fixing member 200 and a binding member 300 are arranged on the pad block 100, the fixing member 200 is used to be fixedly connected to the template 30, and the binding member 300 is used to bind the steel bar 20.

[0029] Specifically, Figure 1 and Figure 2 As shown, by arranging a spacer block 100 between the steel bar 20 and the formwork 30, a certain distance is created between the steel bar 20 and the formwork 30. It should be noted that the height of the spacer block 100 in a direction perpendicular to the surface of the formwork 30 is equal to the design value of the thickness of the protective layer of the steel bar 20. Thus, the distance between the steel bar 20 and the formwork 30 is the design value of the thickness of the protective layer of the steel bar 20. By arranging a fixing member 200 on the spacer block 100 for firmly connecting with the formwork 30, it can be ensured that the spacer block 100 will not shift relative to the formwork 30 during the concrete pouring process, thereby maintaining the relative position and height of the spacer block 100. By arranging a binding member 300 on the spacer block 100 for tightly binding the steel bar 20, it helps to ensure that the relative position between the steel bar 20 and the spacer block 100 does not change during the concrete pouring process.

[0030] In general, this steel bar protective layer thickness control structure allows the steel bar 20 to be reliably connected to the formwork 30 via the pad 100, thereby ensuring that the thickness of the steel bar 20 protective layer of the concrete component is reliably controlled, ensuring the quality and performance of the concrete component and improving the quality of building construction.

[0031] Optionally, the cushion block 100 includes a solid block, and the fixing member 200 and the binding member 300 are respectively disposed through the solid block.

[0032] Specifically, the pad 100 should be a solid block, and its material selection needs to take into account the actual application environment of the construction site. The solid block can be made of high-strength, durable, and corrosion-resistant materials, and can be well combined with concrete and have similar expansion and contraction properties, such as concrete, mortar, marble, granite, and steel bars 20 painted with anti-rust paint, etc., to ensure that it can maintain stability during a long construction process and is not easily affected by external factors. Among them, the solid block is a concrete or mortar solid block, which can have better synergy with the concrete structure on the one hand, ensuring the consistency and coordination of the entire system, and on the other hand, it can make full use of the remaining materials from each pouring to make the pad 100, reducing material waste.

[0033] like Figure 2 As shown, in the solid block, the fixing member 200 is penetrated therein, which means that when the solid block is prepared, it is necessary to consider and reserve the penetration position of the fixing member 200 in advance, which may be achieved by setting a perforation in the mold or implanting the fixing member 200 during the concrete pouring process to ensure that the fixing member 200 forms a reliable connection in the solid block. This method not only helps to enhance the stability of the structure, but also simplifies the subsequent construction process; at the same time, the shape and structure of these fixing members 200 are carefully designed so that the solid block can be tightly connected to the formwork 30. The fixing member 200 can be connected to the formwork 30 by various reliable connection means, such as bolts, nails, clamps or other appropriate mechanical connection methods, to ensure that the pad 100 can be firmly attached to the formwork 30, is not easily displaced, and does not need to occupy extra space.

[0034] like Figure 2 As shown, similarly, the tie piece 300 is also inserted into the solid block. This design can ensure that the tie piece 300 is firmly combined with the solid block to prevent displacement or falling off during use. The positioning of the tie piece 300 needs to fully consider the layout of the steel bars 20 and the pouring method of concrete to ensure that the tie piece 300 can effectively maintain its function throughout the construction process; the shape and material of the tie piece 300 must be able to effectively tie and support the steel bars 20 to ensure that it maintains a stable position during the concrete pouring process. The shape of the tie piece 300 can generally be a wire tie or other metal piece for connection. The shape of the tie piece 300 can be a straight line, annular, spiral or other applicable shape to ensure that the steel bars 20 are firmly tied to avoid any loosening or falling off during the construction process.

[0035] In general, by adopting a solid block made of materials such as mortar or concrete, and inserting the fixing parts 200 and the binding parts 300 therein, this design not only takes into account the durability and stability of the pad 100, but also can achieve a firm connection between the fixing parts 200 and the binding parts 300 in the structure, which helps to improve the control accuracy and reliability of the thickness of the protective layer of the steel bar 20 in construction.

[0036] Optionally, the cushion block 100 further includes a shell, which is detachably wrapped around the outer circumference of the solid block.

[0037] Specifically, wrapping the shell around the outer periphery of the solid block can provide additional protection and support for the solid block. When mortar or concrete is used as the pad 100, the shell can be used as a mold for its solidification. The shell should be made of a strong, corrosion-resistant, and wear-resistant material, such as high-strength plastic, metal, or composite material, to ensure that it can withstand various environmental and mechanical stresses during the construction process. The detachable design of the shell can simplify the manufacturing and maintenance process of the pad 100, because the shell can be manufactured and replaced separately when needed, and different types or sizes of shells can be replaced according to different construction requirements and the arrangement of the steel bars 20, and the detachable design allows the shell to be reused.

[0038] Optionally, the shell is made of PVC pipe. During the construction process, discarded PVC pipe scraps can be collected and reused as the shell to reduce the demand for new raw materials. First, PVC has high corrosion resistance and is not easily corroded by moisture, chemicals or other external environmental factors, so it is very suitable for use in construction scenarios; secondly, PVC pipes have a light weight, which makes the overall weight of the pad 100 relatively light and easier to carry and handle; thirdly, PVC materials generally have excellent durability and can maintain their physical and chemical properties for a long time. This durability is crucial for the long-term use of the pad 100, especially during multiple disassembly and assembly processes, the PVC pipe can maintain its structural integrity and stability; in addition, the cuttability of the PVC pipe allows for simple and effective separation when disassembling the pad 100, and the cut PVC pipe can be reconnected using tape, making it highly reusable; in addition, PVC is a material with good plasticity, which means that PVC pipes can be relatively easily designed and processed as needed, and this feature allows PVC pipes to flexibly adapt to pads 100 of different sizes and shapes to meet the requirements of various steel bar 20 arrangements and concrete structures.

[0039] Optionally, a release layer is provided between the housing and the solid block.

[0040] Specifically, the main function of the release layer is to reduce the adhesion between the shell and the solid block, making it easier for the solid block to detach from the shell, which is very important for maintaining the integrity of the solid block and the shell to avoid damage during the demolding process. The release layer usually selects materials with strong anti-stick properties, such as special coatings, release agents, films or surface treatments, which help reduce friction and adhesion between the solid block and the shell surface, making the demolding process smoother; since the release layer may be subjected to friction and wear during multiple uses, the material of the release layer needs to have good wear resistance to ensure its long-term effectiveness; the release layer can be applied by spraying or brushing on the inner surface of the shell to ensure that an effective isolation layer is formed between the solid block and the shell.

[0041] By providing a demoulding layer between the solid block and the shell, this design takes into account the demoulding effect and the protection of the cushion block 100, thereby improving the recyclability of the shell and ensuring the quality of the solid block.

[0042] Optionally, a first through hole perpendicular to the surface of the template 30 is opened in the cushion block 100, and the fixing member 200 is passed through the first through hole. One end of the fixing member 200 passes through the first through hole and extends outward to a side of the cushion block 100 close to the template 30, and the other end abuts against the cushion block 100.

[0043] Specifically, a position perpendicular to the surface of the template 30 is selected on the cushion block 100, and a first through hole is opened at this position. In order to facilitate the subsequent fixing steps, it is ensured that the fixing member 200 can pass through and cross the surface of the template 30 perpendicularly; by passing the fixing member 200 through the first through hole, it is ensured that the fixing member 200 can be firmly connected to the cushion block 100. This step requires a certain degree of precision to ensure the correct position and direction of the fixing member 200; and after passing the fixing member 200 through the first through hole, one end of the fixing member 200 passing through the first through hole is extended outward from the cushion block 100 close to the template One side of the fixing member 200 is to ensure that the fixing member 200 is effectively connected to the formwork 30 and remains stable during the construction process. It should be noted that when connecting the fixing member 200 to the formwork 30, it may be necessary to use nuts or other fastening devices to firmly connect the fixing member 200 to the formwork 30, so as to ensure the firmness and reliability of the connection; at the same time, the other end of the fixing member 200 needs to be abutted against the cushion block 100 to ensure that it is tightly combined with the cushion block 100. The design of this connection point is intended to provide stable support to ensure that the cushion block 100 is not easily displaced or deformed during use.

[0044] Through the above design, the pad block 100 can be firmly connected to the formwork 30 at the construction site, ensuring stability and accuracy during concrete pouring. Such a design can provide an effective way to maintain the position and direction of the pad block 100 during construction, ensuring the quality and strength of the final structure.

[0045] Optionally, when the solid block of the cushion block 100 is made of fluid such as mortar or concrete, the fixing member 200 can be directly embedded in the solid block after the mortar or concrete is initially set and before the final setting, so as to achieve a reliable connection between the solid block and the fixing member 200. The embedding of the fixing member 200 should have an appropriate depth to ensure that it can be firmly fixed in the cushion block 100 after the concrete is poured.

[0046] Optionally, a second through hole parallel to the surface of the template 30 is opened in the cushion block 100 , the binding member 300 is passed through the second through hole, and two ends of the binding member 300 extend outward at opposite sides of the cushion block 100 .

[0047] Specifically, a position is selected on the pad 100 parallel to the surface of the template 30, and a second through hole is opened at this position, so as to fix the pad 100 and the steel bar 20 through the tie 300, and ensure the stability of the steel bar 20 relative to the pad 100 when the concrete is poured; the tie 300 is passed through the second through hole to ensure that it can be effectively connected to the pad 100. This process requires a certain degree of precision to ensure that the position and direction of the tie 300 meet the design requirements; the two ends of the tie 300 are extended outward on the opposite sides of the pad 100 to firmly fix the tied steel bar 20 on the pad 100. This step is to ensure that the steel bar 20 can be tightly combined with the pad 100 when the concrete is poured, so as to improve the strength and stability of the overall structure. The tie 300 can be designed as a wire tie, which has a certain flexibility and can be adjusted and used according to the actual construction needs. The wire tie method is often used to connect the steel bar 20 to ensure that the steel bar 20 can be properly supported and fixed when the concrete is poured.

[0048] Through the above design, the binding members 300 are fixedly connected in the pad 100, and the fixed binding steel bars 20 are used to ensure the stability of the pad 100 during concrete pouring. Such a design can provide a flexible and reliable method in construction, thereby ensuring the quality and strength of the overall structure.

[0049] Optionally, when the solid block of the pad 100 is made of fluid such as mortar or concrete, the binding member 300 can be directly embedded in the solid block after the mortar or concrete has initially set and before the final setting, so as to ensure that the binding member 300 is firmly combined with the solid block to provide a firm connection.

[0050] Optionally, a through groove 110 is provided on a side of the cushion block 100 close to the steel bar 20 , and the through groove 110 is used to accommodate the steel bar 20 .

[0051] Specifically, Figure 1 and Figure 2As shown, a side close to the steel bar 20 is selected on the cushion block 100, and a through groove 110 is opened at this position. This setting is to facilitate the placement of the steel bar 20 on the cushion block 100, so as to achieve an effective combination of the cushion block 100 and the steel bar 20; the shape and size of the through groove 110 should be able to adapt to the shapes and sizes of various steel bars 20, which helps to ensure that the steel bar 20 can be firmly placed in the through groove 110, provide good support and fixation, and prevent the steel bar 20 from shifting or offset during concrete pouring; the design of the through groove 110 makes it easier to install the steel bar 20 at the construction site, and construction personnel can easily place the steel bar 20 into the through groove 110 to ensure its correct position and direction.

[0052] By opening a through groove 110 on one side of the pad 100 close to the steel bar 20, this design can ensure that the steel bar 20 can be firmly and stably accommodated on the pad 100 when the concrete is poured. Such a design helps to improve the strength and stability of the overall structure, while simplifying the installation steps of the steel bar 20 during the construction process.

[0053] Optionally, there are two through grooves 110 , and the two through grooves 110 are perpendicular to each other.

[0054] Specifically, Figure 1 and Figure 2 As shown, two positions are selected on the pad 100, and two through grooves 110 are set respectively. The two positions should make the two grooves perpendicular to each other and meet the design requirements of the concrete structure. The two through grooves 110 are arranged perpendicular to each other to improve the connection stability between the pad 100 and the steel bar 20. Such a layout helps to prevent the steel bar 20 from accidentally moving or offsetting during the construction process; the design of two vertical through grooves 110 can provide greater flexibility to accommodate steel bars 20 in different directions, which is very beneficial for handling the arrangement of steel bars 20 in multiple directions; the size and shape of the two through grooves 110 should be coordinated to ensure that they can accommodate steel bars 20 of different diameters and shapes and maintain consistency throughout the structure.

[0055] By providing two mutually perpendicular through grooves 110 on the pad 100, this design is used to provide a reliable way to enhance the connection stability between the pad 100 and the steel bar 20, and improve the construction accuracy and stability of the overall concrete structure. Such a design has a positive impact on ensuring the structural quality and performance.

[0056] Optionally, the intersection of the two through grooves 110 is located at the center of a side of the cushion block 100 close to the steel bar 20 .

[0057] Specifically, Figure 1 and Figure 2As shown, on the side of the pad 100 close to the steel bar 20, a central position is selected as the intersection of the two through grooves 110. The position of the intersection should be adapted to the size and shape of the pad 100 to ensure that the layout of the two through grooves 110 has a suitable position and space on the pad 100; the setting at the intersection should ensure that the transition between the two through grooves 110 is smooth, without protrusions or depressions, so as to avoid uneven stress when placing the steel bar 20; setting the intersection at the center of the pad 100 helps to improve the overall stability of the pad 100 and the steel bar 20, which is crucial for the long-term stability of the concrete structure. By selecting a central position on the pad 100, the intersection of the two through grooves 110 is located at the center of the side of the pad 100 close to the steel bar 20 to ensure the overall balance and stability of the structure. Such a layout helps to ensure that when the concrete is poured, the setting of the through grooves 110 is uniform for supporting and fixing the steel bar 20, thereby improving the quality and performance of the overall structure.

[0058] Alternatively, if Figure 2 As shown, the fixing member 200 is embedded in the intersection of the two through grooves 110, that is, the center of the pad 100. This choice ensures that the fixing member 200 is evenly distributed on the pad 100 and is aligned with the center of the overall structure. It should be noted that the top of the fixing member 200 should be set flush with the bottom of the through groove 110. This design can ensure that the fixing member 200 does not protrude into the through groove 110, thereby not affecting the placement of the steel bar 20.

[0059] In this embodiment, the manufacturing process of the cushion block 100 is specifically as follows:

[0060] Before making the cushion block 100, firstly, a release agent is evenly applied on the inner wall of the PVC pipe. The use of the release agent helps to reduce the adhesion between the concrete and the PVC pipe, making it easier to demould the cushion block 100.

[0061] Select a flat ground, erect the PVC pipe on the ground, and then pour concrete with the same or higher strength grade as the main structural member into the PVC pipe to ensure that the strength of the pad 100 can match the requirements of the main structure;

[0062] After the initial setting of the concrete and before the final setting, a first through hole perpendicular to the board surface of the template 30 or a directly embedded fixing member 200 is opened in the cushion block 100, and a second through hole parallel to the board surface of the template 30 is opened in the cushion block 100 to embed the tying member 300. The first through hole, the second through hole, the fixing member 200 and the tying member 300 are provided to facilitate the subsequent construction and fixing process;

[0063] After the concrete is finally set, the PVC pipe is cut vertically using a blade. The purpose of this step is to remove the PVC pipe from the pad 100 to reveal the formed solid block and ensure that the pad 100 can be easily demoulded while maintaining its integrity.

[0064] The formed solid blocks should be gathered together after demolding and properly watered and cured. This step helps to keep the solid blocks moist and promote the strength development of the concrete. Only after the concrete reaches the required strength can these solid blocks be set between the steel bars 20 and the formwork 30.

[0065] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
