Description

Technical Field

[0001] The utility model relates to the technical field of plastic pads for controlling the thickness of a steel bar protective layer, in particular to a plastic pad for controlling the thickness of a steel bar protective layer. Background Art

[0002] Rebar is an indispensable material in construction projects and has a wide range of uses. In order to prevent it from rusting and carbonizing in the natural environment, a protective layer is usually poured during the construction process. The rebar is placed on plastic pads. The thickness of the plastic pads determines the thickness of the protective layer that needs to be poured.

[0003] The Chinese patent "A new type of pad for controlling the thickness of the steel bar protective layer" authorization announcement number "CN213038686U" realizes the steel bar being stuck in the first groove and the two pad bodies being assembled through the pad body, the first groove, the second groove, the first clamping groove and the second clamping groove, and has good versatility.

[0004] The above-mentioned steel bars are simply stuck in the second groove, which makes the installation of the pad body on the steel bars unstable, and easily causes the pad body to fall off the steel bars, thereby causing the thickness of the cast steel bar protective layer to be uneven.

[0005] Therefore, a plastic pad for controlling the thickness of the steel bar protective layer is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a plastic pad for controlling the thickness of the steel bar protective layer in order to solve the above-mentioned problem, thereby improving the problem that the pad body is unstable when installed on the steel bar, thereby causing uneven thickness of the cast steel bar protective layer.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a plastic pad for controlling the thickness of a steel bar protective layer, comprising: a first pad, a second pad being hinged on the top of the first pad; a fixing mechanism, used to ensure that the plastic pad is stably installed on the steel bar, and the fixing mechanism is arranged on the surface of the first pad; wherein the fixing mechanism comprises anti-sliding blocks fixedly connected to the inner side of the first pad and distributed in equal rows, the inner wall of the second pad is slidably connected to a positioning frame distributed in an annular manner, the end of the positioning frame is fixedly connected to a first spring, the other end of the first spring is fixedly connected to the inner wall of the second pad, and a fixing component is arranged on the surface of the first pad.

[0008] Preferably, the fixing assembly includes a fixing rod slidably connected to the inner wall of the first pad, the surface of the fixing rod is clamped to the inner wall of the second pad, one end of the fixing rod is fixedly connected to a second spring, and the other end of the second spring is fixedly connected to the inner wall of the first pad. The first spring, the positioning frame and the anti-sliding block are used to achieve the inner side of the plastic pad to resist the steel bar, ensuring that the plastic pad can resist steel bars of different diameters. The second spring and the fixing rod are used to achieve the first pad and the second pad being locked on the steel bar, thereby ensuring the stability of the plastic pad on the steel bar, thereby ensuring the uniformity of the thickness of the cast steel bar protective layer.

[0009] Preferably, the mounting block is fixedly connected to the top of the second cushion block, a fixing block is fixedly connected to the inner side of the mounting block, a fixing groove is formed at one end of the first cushion block, and a surface of the fixing block is snapped onto the inner wall of the fixing groove.

[0010] Preferably, the fixing block is curved in an arc shape. The mounting block, the fixing block and the fixing groove are used to realize the clamping assembly of the two sets of plastic cushion blocks, thereby ensuring the stability of the plastic cushion blocks after assembly.

[0011] Preferably, one end of the fixing rod is fixedly connected to a sliding rod, so that the inner wall of the first pad is slidably connected to the surface of the sliding rod. The sliding rod is used to move the sliding rod away from the second pad, thereby unlocking the first pad and the second pad, and the separation of the plastic pad and the steel bar is simple.

[0012] Preferably, the anti-sliding block and the fixing block are both made of rubber. The anti-sliding block made of rubber can increase the friction between the first pad and the steel bar, thereby ensuring the stability of the plastic pad installed on the steel bar, and the fixing block made of rubber can ensure that one of the first pads can be moved and connected in the installation block.

[0013] Preferably, the end of the positioning frame is bent into an arc shape. By using the positioning frame with an arc-shaped end, the positioning frame can better contact the steel bar, increase the friction between the plastic pad and the steel bar, and thus ensure the stability of the plastic pad installed on the steel bar.

[0014] Preferably, the inner sides of the first pad and the second pad are both concave in a "V" shape. By using the first pad and the second pad with the inner sides concave in a "V" shape, it is ensured that the plastic pad can be installed on steel bars of different diameters, thereby improving the practicality of using the plastic pad.

[0015] The beneficial effects of the utility model are:

[0016] 1. The first spring, the positioning frame and the anti-sliding block are used to make the inner side of the plastic pad contact the steel bar, ensuring that the plastic pad can contact steel bars of different diameters.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-4As shown, a plastic pad for controlling the thickness of a steel bar protective layer comprises: a first pad 1, a second pad 2 being hinged on the top of the first pad 1; a fixing mechanism 3 for ensuring that the plastic pad is stably installed on the steel bar, and the fixing mechanism 3 is arranged on the surface of the first pad 1; wherein the fixing mechanism 3 comprises anti-sliding blocks 31 fixedly connected to the inner side of the first pad 1 and distributed in equal rows, and a positioning frame 32 distributed in an annular manner is slidably connected to the inner wall of the second pad 2, and a first spring 33 is fixedly connected to the end of the positioning frame 32, and the other end of the first spring 33 is fixedly connected to the inner wall of the second pad 2, and a fixing component 34 is arranged on the surface of the first pad 1, and the inner sides of the first pad 1 and the second pad 2 are both recessed in a "V" shape.

[0026] It should be noted that in the above description, the first cushion block 1 and the second cushion block 2 are both made of plastic material, which are relatively mature devices in the existing technology. The specific model can be selected according to actual needs.

[0027] When the plastic pad needs to be installed on the steel bar, open the first pad 1 and the second pad 2, so that the anti-sliding block 31 on the inner side of the first pad 1 abuts against the corresponding position of the steel bar, rotate the second pad 2 so that the second pad 2 is inserted into the first pad 1, and the elastic force of the first spring 33 pushes the positioning frame 32 to move and abut against the steel bar.

[0028] like Figure 4 As shown, the fixing assembly 34 includes a fixing rod 344 slidably connected to the inner wall of the first cushion block 1, the surface of the fixing rod 344 is clamped on the inner wall of the second cushion block 2, one end of the fixing rod 344 is fixedly connected to the second spring 345, and the other end of the second spring 345 is fixedly connected to the inner wall of the first cushion block 1.

[0029] The elastic force of the second spring 345 pushes the fixing rod 344 to move and engage in the second pad 2, thereby locking the second pad 2 on the first pad 1, so that the first pad 1 and the second pad 2 are installed on the steel bar. At this time, the plastic pad is installed on the steel bar and then poured.

[0030] like Figure 3 As shown, a mounting block 341 is fixedly connected to the top of the second cushion block 2, a fixing block 342 is fixedly connected to the inner side of the mounting block 341, a fixing groove 343 is opened at one end of the first cushion block 1, the surface of the fixing block 342 is clamped to the inner wall of the fixing groove 343, and the shape of the fixing block 342 is curved in an arc shape.

[0031] When the two plastic cushion blocks need to be assembled, one of the first cushion blocks 1 is moved into the mounting block 341 so that the fixing block 342 is snapped into the fixing groove 343 , thereby snapping and assembling the two plastic cushions.

[0032] like Figure 4As shown, one end of the fixing rod 344 is fixedly connected to a sliding rod 346, so the inner wall of the first cushion block 1 is slidably connected to the surface of the sliding rod 346. Pulling the sliding rod 346, the sliding rod 346 moves and drives the fixing rod 344 away from the second cushion block 2, pulling the second cushion block 2, and then releasing the plastic cushion block from the steel bar.

[0033] When the utility model is in use, the first pad 1 and the second pad 2 are opened, so that the anti-sliding block 31 on the inner side of the first pad 1 is in contact with the corresponding position of the steel bar, and the second pad 2 is rotated so that the second pad 2 is inserted into the first pad 1. The elastic force of the second spring 345 pushes the fixing rod 344 to move and clamp it in the second pad 2, so that the second pad 2 is locked on the first pad 1, so that the first pad 1 and the second pad 2 are installed on the steel bar, and the elastic force of the first spring 33 pushes the positioning frame 32 to move and contact the steel bar. At this time, the plastic pad is installed on the steel bar and then poured.
