The reinforcement protection layer refers to the distance from the outer edge of the outermost reinforcement to the concrete surface, that is, the distance from the outer edge of the stirrup to the concrete surface, and can protect the reinforcement from being corroded.
The reinforcement protection layer thickness control device provided by the utility model is formed by combining the first protection piece and the second protection piece which are symmetrically arranged, and the structural components are simple to form. Wherein, the first protection piece and the second protection piece are respectively provided with a part of accommodating cavity, and when the first protection piece and the second protection piece are joggled together, a complete accommodating cavity can be formed. When the device is used, an operator can buckle the first protection piece on one side of the steel bar, and the first accommodating cavity can wrap part of the surface of the steel bar; the second protection piece is buckled on the other side of the steel bar, and the second accommodating cavity can wrap the remaining surface of the steel bar. After the first protection piece and the second protection piece are joggled and fixed, a reinforcement protection layer thickness control device can be fixed outside the reinforcement and used for assisting the pouring of the follow-up reinforcement protection layer, and the operation is flexible and simple.
Concrete is poured downwards from the top end, and part of the concrete enters the storage cavity of the control device from the through hole. The storage cavity is automatically filled up as the concrete is poured downwards continuously, and the whole thickness control device is wrapped by the concrete, so that a reinforcement protection layer is formed. The thickness of the reinforcement protection layer is determined by the specification of the thickness control device, and different reinforcement thicknesses are realized by the thickness control devices with different specifications. After a thickness control device with proper specification is selected, the thickness of the reinforcement protection layer can be determined by the established specification of the control device.
The through holes and the storage cavity can help the concrete circulate in the control device, so that the control device is filled with the concrete as much as possible, and the overall quality of the reinforced protection layer is not reduced due to the fact that holes are not easy to appear.
The first protection piece and the second protection piece are made of plastic with a certain degree, and on one hand, the production cost can be greatly reduced by using the plastic material; on the other hand, high strength plastics facilitate the joggling of the first and second protection members.
The concrete use of this protective layer thickness control device of reinforcing bar is: in general construction, the reinforcing bars are usually in the form of a reinforcing bar frame, and the reinforcing bar frame is usually a reinforcing cage formed by bundling a plurality of transverse reinforcing bars and a plurality of vertical reinforcing bars. The first protection piece and the second protection piece are respectively buckled on two sides of the steel bar to be protected. Pouring concrete downwards from the topmost end, enabling the concrete to flow through the surface of the reinforcement protection layer thickness control device or flow into the through hole to enter the storage cavity, and continuously flowing downwards for a certain time to form a reinforcement protection layer; or the steel bar enters the control device through a gap between the accommodating cavity and the steel bar, so as to help the steel bar to be further tightly combined with the control device. At this time, the control device is wrapped in concrete and becomes a part of the thickness protection layer; and the reinforcing steel bar protection layer is the thickness between the reinforcing steel bars and the concrete wrapped on the outer surface of the control device.
Preferably, the hinge assembly further comprises a hinge assembly, wherein the hinge assembly comprises a first hinge with one end fixedly connected with the first protection piece, the first hinge is far away from the second hinge which is movably connected with the other end of the first protection piece, and the second hinge is far away from the other end of the first hinge and is fixedly connected with the second protection piece.
In order to facilitate the one-hand buckling of the first protection piece and the second protection piece, a hinge assembly arranged at the top ends of the first protection piece and the second protection piece (or avoiding all endpoints outside the position of the containing cavity) is added. One end of the first hinge is movably connected with one end of the second hinge, the other end of the first hinge is fixedly connected with the first protection piece, and the other end of the second hinge is fixedly connected with the second protection piece.
Preferably, the size of the accommodating cavity is consistent with the specification of the steel bars to be passed.
The accommodating cavity is a reserved space for the steel bars with different specifications to pass through, and can be used in cooperation with the steel bars with different specifications, so that the accommodating cavity can be set to be of various specifications. However, it should be noted that the size of the accommodating cavity cannot be too much larger (slightly 1-2 mm larger) than the size of the steel bar to be passed through, which would otherwise cause the first protection member and the second protection member to be buckled and then not attached to the surface of the fixed steel bar, resulting in the protection member sliding downward. When the height is slightly larger than 1-2 mm, the ribs on the surface of the steel bar can be used for limiting certain positions, and the steel bar is not easy to slide downwards.
Preferably, a tenon is arranged on one side, close to the second protection piece, of the first protection piece, and a mortise corresponding to the tenon is arranged on one side, close to the first protection piece, of the second protection piece.
The inventor of the utility model has tenon on the first protective piece, and mortise is arranged on the second protective piece at the corresponding position; the first and second protection members can be fastened together in a joggle manner.
Preferably, the tenons are uniformly distributed on one side of the first protection piece, which is close to the second protection piece.
The tenon evenly disperses and sets up can help first protection piece and second protection piece tenon ground connection more firm. If the tenons are arranged at a certain position in a concentrated way, the similar buckling effect can be achieved, but the tenons are easy to loosen.
Preferably, the number of tenons is at least 3.
On the basis of uniform dispersion, at least 3 tenons are arranged on the first protection piece, and the position points of the 3 tenons are connected to form an isosceles triangle. The purpose of this arrangement is to form a stable triangular structure with evenly distributed positions, and with a minimum of tenon structures, the best stability is achieved.
Preferably, the first protection piece and the second protection piece form a sphere after joggling.
The first protection piece and the second protection piece can form a sphere after joggling. The advantage of being configured as a sphere is that when concrete is poured down, the curved surface of the sphere allows better downward flow of the concrete without binding the concrete to the surface of the protector. When the first protection piece and the second protection piece are joggled to form a square body, the concrete is easy to stay on the first surface of the square body, which is contacted with the concrete, and the concrete cannot continuously flow downwards, so that the formation of the reinforcement protection layer is not facilitated.
The ellipsoid formed after the joggling of the first protective piece and the second protective piece can also enable the concrete to smoothly flow downwards along the arc-shaped surface. But ellipsoids are less good than spheres in that: when the reinforcing steel bar protection layer is formed, the radius from the sphere to the sphere center is uniform, so that the thickness of the formed protection layer is uniform.
Preferably, the through holes are uniformly distributed on the surfaces of the first protection piece and the second protection piece.
The through holes are uniformly distributed, so that the flow of the concrete at each position can be assisted; the uneven distribution may cause uneven concrete distribution at part of the positions, and the formed reinforcement protection layer has different thickness. The through holes may be provided on any surface of the first protector and the second protector.
Preferably, the area of the through hole is less than or equal to one half of the size of an end surface of the first protection member away from the accommodating cavity/an end surface of the second protection member away from the accommodating cavity.
The area of the through holes is too large, and accordingly, the number of the through holes is small, so that the flow of concrete is not facilitated. When the through hole on the side surface of the first protection piece is close to the area of the side surface of the first protection piece, the area of the through hole is overlarge at the moment, and only one large through hole can be arranged on the side surface of the first protection piece, so that the circulation of concrete in the through hole is not facilitated.
Therefore, the utility model has the following beneficial effects:
(1) The thickness control device of the reinforcement protection layer designed by the utility model consists of the first protection piece and the second protection piece, wherein the first protection piece and the second protection piece can form a containing cavity for the reinforcement to pass through after joggling, and the structure is simple;
(2) The thickness control device for the reinforcement protection layer designed by the utility model can realize fixation after being buckled on two sides of the reinforcement, and the assembly mode is simple;
(3) The hinge assembly designed by the utility model can help the first protection piece and the second protection piece to be integrated in a state of not joggling, is convenient for one-hand operation in the subsequent installation process, and greatly saves the installation time;
(4) The device for controlling the thickness of the reinforcement protection layer has simple structure composition, is made of plastic, has low production and manufacturing cost, and is suitable for wide production and application.

The first protection member 100 is provided with a first accommodating cavity 310 at a side close to the second protection member 200, and the second protection member 200 is provided with a second accommodating cavity 320 at a side close to the first protection member 100. The first and second protection members 100 and 200 are each provided therein with a storage chamber 500 for storing concrete, and the surfaces of the first and second protection members 100 and 200 are uniformly and dispersedly provided with through holes 600 for facilitating inflow of concrete, the through holes 600 being communicated with the storage chamber 500.
The first and second protective members 100 and 200 are each provided with a partial receiving cavity 300, and when they are joggled together, a complete receiving cavity 300 is formed. In use, an operator may buckle the first protector 100 to one side of the reinforcing bar, and the first receiving cavity 310 may wrap a portion of the surface of the reinforcing bar; the second protector 200 is fastened to the other side of the reinforcing bar, and the second receiving chamber 320 may wrap the remaining surface of the reinforcing bar. After the first protection piece 100 and the second protection piece 200 are joggled and fixed, a reinforcement protection layer thickness control device can be fixed outside the reinforcement for assisting the subsequent reinforcement protection layer pouring.
The storage cavity 500 on the protection member can store the poured concrete through the through hole 600, the concrete continuously flows down until the storage cavity 500 is filled, and the concrete wraps the whole thickness control device, so that a reinforcement protection layer is formed. The thickness of the reinforcement protection layer is determined by the specification of the thickness control device, and different reinforcement thicknesses are realized by the thickness control devices with different specifications. After a thickness control device with proper specification is selected, the thickness of the reinforcement protection layer can be determined by the established specification of the control device.
The side of the first protection piece 100 close to the second protection piece 200 is also provided with 6 tenons 110, and the side of the second protection piece 200 close to the first protection piece 100 is also provided with 6 mortises 210 corresponding to the positions of the tenons 110.
