Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to an adjustable steel reinforcement protective layer device. Background Technology

[0002] In construction engineering, reinforced concrete structures are widely used. The concrete cover refers to the layer of concrete in a concrete member that extends from the outer edge of the reinforcing bar to the concrete surface. The thickness of the concrete cover plays a crucial role in ensuring the bond between the reinforcing bar and the concrete, preventing the reinforcing bar from corroding, and ensuring the durability and safety of the structure.

[0003] However, the existing traditional steel reinforcement protective layer spacers are made of mortar spacers, which are fixed products. During the installation process, they may be not tied firmly, and the size control may be inaccurate, resulting in large deviations in the steel reinforcement protective layer after construction. In addition, there are often obvious spacer marks on the outer surface of the concrete, and voids may even occur at the spacer positions due to insufficient vibration.

[0004] To address this, an adjustable rebar cover device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable rebar protective layer device, which can solve the problems of existing traditional rebar protective layer spacers made of mortar, which are fixed products. During the installation process, they may be not firmly tied, and the size control may be inaccurate, resulting in large deviations in the rebar protective layer after construction. In addition, there are often obvious spacer marks on the outer surface of the concrete, and voids may even occur at the spacer position due to insufficient vibration.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable rebar protective layer device, comprising a channel-shaped steel sheet, wherein an adjustment support mechanism is provided at the bottom of the channel-shaped steel sheet;

[0007] The adjusting support mechanism includes slots, nuts, screws, a hemispherical mortar mold, high-strength mortar, and a base structure. The slots are respectively opened on the front and rear sides of the bottom inside the channel steel sheet. The nuts are respectively welded to the front and rear sides of the bottom inside the channel steel sheet. The nuts are located at the top of the slots. The screw is threaded into the inside of the nuts. The bottom of the screw penetrates the inside of the slots. The hemispherical mortar mold is located on the outside of the bottom of the screw. The high-strength mortar fills the inside of the hemispherical mortar mold. The high-strength mortar is located on the outside of the screw. The base structure is set at the bottom of the hemispherical mortar mold.

[0008] Preferably, the base structure includes a fixing seat disposed at the bottom of the hemispherical mortar mold, and the internal dimensions of the fixing seat match the dimensions of the high-strength mortar after solidification.

[0009] Preferably, a seat plate is fixedly connected to the bottom of the fixed base, and a support rod is fixedly connected to the outer side of the fixed base, with the bottom of the support rod fixedly connected to the top of the seat plate.

[0010] Preferably, a smooth-fitting pad is fixedly connected to the bottom of the seat, and the smooth-fitting pad is made of synthetic rubber material.

[0011] Preferably, the interior of the channel-shaped steel sheet is hollow, and the two sides and the bottom of the channel-shaped steel sheet are connected to each other to form a regular groove-shaped space.

[0012] Preferably, arc-shaped guide plates are welded to both sides of the top of the channel steel sheet, and the inner side of the arc-shaped guide plate is semi-circular.

[0013] Preferably, a hexagonal block is welded to the top of the lead screw, and the hexagonal block has the same size as the nut.

[0014] Preferably, the bottom of the smooth-fitting pad has anti-slip stripes, which are distributed in a crisscross pattern.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application achieves precise control of the concrete cover thickness of reinforcing bars by setting up an adjustable support mechanism. Specifically, an adjustable screw rod is equipped on the channel steel plate, and the screw rod is threadedly connected to a nut welded to the channel steel plate. The channel steel plate can be easily clamped onto two adjacent reinforcing bars. By rotating the screw rod, the height of the channel steel plate can be easily and flexibly adjusted, thereby changing the thickness of the concrete cover. In addition, one end of the screw rod is inserted into a hemispherical mortar mold and filled with high-strength mortar. After demolding, it can provide stable support for the device. This design effectively avoids the problem of uneven concrete cover thickness caused by the easy displacement of traditional spacers during concrete pouring, ensuring the reliability of the construction quality of the concrete cover.

[0017] 2. This application, by setting a base structure, after the high-strength mortar at the bottom of the screw rod solidifies and is demolded in the hemispherical mortar mold, the high-strength mortar is then firmly fixed to the base structure. In this way, the base structure can provide a solid bottom support for the adjustment support mechanism. During the concrete vibration process, this structure can effectively resist the influence of the vibration force and prevent the device from shifting or deforming. Compared with traditional pads, which are prone to leaving marks on the outer surface of the concrete and may produce voids due to inadequate vibration, this method can make the concrete surface smoother, avoid the formation of voids, and ensure the integrity of the overall structure.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] An adjustable rebar protective layer device includes a channel-shaped steel sheet 1, and an adjustment support mechanism 2 is provided at the bottom of the channel-shaped steel sheet 1;

[0027] The adjusting support mechanism 2 includes a slot 201, a nut 202, a lead screw 203, a hemispherical mortar mold 204, high-strength mortar 205, and a base structure 206. The slot 201 is respectively opened on the front and rear sides of the bottom inside the channel steel sheet 1. The nut 202 is respectively welded to the front and rear sides of the bottom inside the channel steel sheet 1. The nut 202 is located at the top of the slot 201. The lead screw 203 is threaded into the inside of the nut 202. The bottom of the lead screw 203 penetrates the inside of the slot 201. The hemispherical mortar mold 204 is located on the outside of the bottom of the lead screw 203. The high-strength mortar 205 is filled inside the hemispherical mortar mold 204. The high-strength mortar 205 is located on the outside of the lead screw 203. The base structure 206 is set at the bottom of the hemispherical mortar mold 204.

[0028] In this embodiment: by setting the channel-shaped steel plate 1 and the adjusting support mechanism 2, the channel-shaped steel plate 1 can be easily clamped onto two adjacent steel bars to achieve initial positioning. The slot 201 in the adjusting support mechanism 2 reserves space for the vertical movement of the lead screw 203. The nut 202 welded on the channel-shaped steel plate 1 is threadedly connected to the lead screw 203. When the lead screw 203 is rotated, relying on the threaded engagement between the lead screw 203 and the nut 202, the lead screw 203 can move precisely up and down in the vertical direction. The bottom of the lead screw 203 is inserted into the hemispherical mortar mold 204, and the hemispherical mortar mold 204 is filled with high-strength mortar 205. In the initial installation stage, by adjusting the height of the lead screw 203, the channel-shaped steel plate 1 can be positioned. The steel section 1 is adjusted to a position that meets the requirements for the thickness of the concrete cover. Then, after the high-strength mortar 205 solidifies, it is removed from the hemispherical mortar mold 204, and the solidified high-strength mortar 205 is firmly connected to the base structure 206. In this way, the base structure 206 can provide a stable bottom support for the adjustment support mechanism 2, ensuring that the entire device remains stable during concrete vibration and pouring. This design allows the thickness of the concrete cover to be flexibly adjusted according to actual needs during the construction process, while also ensuring the stability of the device during subsequent construction operations. It prevents deviations in the thickness of the concrete cover due to device movement, thus ensuring the accuracy and uniformity of the concrete cover thickness.

[0029] Specifically, such as Figure 3 As shown, the base structure 206 includes a fixing seat 2061 disposed at the bottom of the hemispherical mortar mold 204, and the internal dimensions of the fixing seat 2061 match the solidified dimensions of the high-strength mortar 205.

[0030] Specifically, such as Figure 3 As shown, a seat plate 2062 is fixedly connected to the bottom of the fixed base 2061, and a support rod 2063 is fixedly connected to the outside of the fixed base 2061. The bottom of the support rod 2063 is fixedly connected to the top of the seat plate 2062.

[0031] Specifically, such as Figure 3 As shown, a smooth-fitting pad 2064 is fixedly connected to the bottom of the seat 2062. The smooth-fitting pad 2064 is made of synthetic rubber material.

[0032] In this embodiment: by setting a base structure 206, after the high-strength mortar 205 solidifies in the hemispherical mortar mold 204, it is removed from the hemispherical mortar mold 204, and the solidified high-strength mortar 205 is firmly connected to the fixed seat 2061. The bottom of the fixed seat 2061 is connected to the seat plate 2062, and the outside is connected to the support rod 2063, which is connected to the seat plate 2062. This structure forms a stable frame that can withstand the pressure from above. The flat and fitting pad 2064 at the bottom of the seat plate 2062 is made of synthetic rubber material, which has a certain elasticity and flexibility. When placed on the ground, it can effectively buffer the impact force on the device. At the same time, the properties of synthetic rubber make it have good durability. The entire base structure 206 can provide solid and stable support during concrete vibration and pouring, ensuring the overall stability of the device, preventing the device from being displaced or deformed due to external forces, and ensuring the accuracy and uniformity of the thickness of the steel reinforcement protective layer.

[0033] Specifically, such as Figure 4 As shown, the interior of the channel steel sheet 1 is hollow, and the two sides and the bottom of the channel steel sheet 1 are connected to each other to form a regular groove-shaped space.

[0034] Specifically, such as Figure 4 As shown, arc-shaped guide plates 3 are welded to both sides of the top of the channel steel sheet 1, and the inner side of the arc-shaped guide plate 3 is semi-circular.

[0035] In this embodiment: by setting an arc-shaped guide plate 3, the hollow state and groove-shaped space of its channel steel sheet 1 reduce its own weight while ensuring structural strength, making installation and operation easier. The groove-shaped space can be easily clamped onto two adjacent steel bars to achieve initial positioning and fixation of the steel bars. At the same time, the arc-shaped guide plate 3 is welded to the top two sides of the channel steel sheet 1, and its inner semi-circular arc shape can better fit with the steel bars, guiding the steel bars into the appropriate position. Meanwhile, during the concrete pouring process, it prevents the steel bars from detaching from the clamping of the channel steel sheet 1 due to external forces, further ensuring the stability of the steel bar position, ensuring that the thickness of the steel bar protective layer remains consistent during construction, and improving the construction quality.

[0036] Specifically, such as Figure 2 As shown, a hexagonal block 4 is welded to the top of the lead screw 203, and the hexagonal block 4 has the same size as the nut 202.

[0037] Specifically, such as Figure 5 As shown, the bottom of the smooth-fitting pad 2064 has anti-slip stripes 5, which are distributed in a crisscross pattern.

[0038] In this embodiment: by setting hexagonal block 4 and anti-slip stripes 5, the hexagonal block 4 at the top of the lead screw 203 is the same size as the nut 202, which facilitates the use of a hexagonal wrench to rotate the lead screw 203. When adjusting the height of the lead screw 203, the up and down movement of the lead screw 203 can be controlled more precisely, thereby accurately adjusting the thickness of the steel reinforcement protective layer. At the same time, the cross-shaped anti-slip stripes 5 at the bottom of the smooth contact pad 2064 can increase the friction between the smooth contact pad 2064 and the placement surface, preventing the device from sliding due to external forces during use, ensuring the stability of the device during construction, and further ensuring the accuracy of steel reinforcement protective layer thickness adjustment and the reliability of the entire device during operation.

[0039] Working Principle: In the use of the adjustable rebar protective layer device, firstly, the channel steel plate 1, with its hollow internal structure and regular groove-shaped space, reduces its own weight while conveniently clamping onto two adjacent rebars, achieving initial positioning. The arc-shaped guide plates 3 welded to its top two sides have an inner semi-circular arc shape that fits tightly with the rebar, guiding the rebar into position. They also prevent the rebar from detaching due to external force during subsequent concrete pouring, ensuring the stability of the rebar position. Then, the slot 201 provides space for the screw rod 203 to move up and down. The nut 202 welded to the channel steel plate 1 is threaded into the screw rod 203. The hexagonal block 4 at the top of the screw rod 203 is the same size as the nut 202, facilitating the use of a hex wrench to rotate the screw rod 203, achieving precise vertical up and down movement. During initial installation, the height of the screw rod 203 is adjusted so that the channel steel plate 1 reaches the desired rebar protective layer thickness. The device is inserted into a hemispherical mortar mold 204 containing high-strength mortar 205. After the high-strength mortar 205 solidifies, it detaches from the interior of the hemispherical mortar mold 204 and then tightly connects to the fixing seat 2061 of the base structure 206. The bottom plate 2062 and the outer support rod 2063 of the fixing seat 2061 form a stable frame to bear the pressure from above. The bottom of the plate 2062 has a smooth, flat pad 2064 made of synthetic rubber, which combines elasticity, flexibility, and durability to buffer the impact. The anti-slip stripes 5 on the bottom of the pad increase the friction with the placement surface and prevent the device from sliding. The overall coordination allows all components of the device to work together during concrete vibration and pouring. This allows for flexible adjustment of the thickness of the steel reinforcement protective layer according to actual conditions, while ensuring its own stability and preventing deviations in the thickness of the steel reinforcement protective layer caused by device movement. This ensures the accuracy and uniformity of the steel reinforcement protective layer and effectively improves the quality of concrete components.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
