[0002] Concrete quality inspection, also known as concrete quality testing, can be divided into three main aspects: internal quality, surface quality, and dimensional quality. The evaluation of concrete strength should be carried out in batches. The concrete in the same acceptance batch should be composed of mixed concrete with the same strength grade, mix proportion, and production process. For cast-in-place concrete, acceptance batches are divided according to sub-projects, and for precast concrete components, batches are divided according to months.

[0003] Chinese patent CN215339308U discloses an observation and control device for concrete quality inspection. This patent discloses a convenient operation technical solution, which solves the problems of existing concrete quality inspection methods that are inconvenient to operate, cannot intuitively detect its compressive strength, and are prone to misplacement when placing the sample to be tested, causing the sample and the extrusion mechanism to shift, resulting in erroneous data.

However, when concrete samples are placed on the placement plate, there is a lack of limiting points. When the extrusion plate squeezes the sample, it is easy for the concrete to move, which reduces the detection effect. Therefore, a concrete limiting device for construction engineering quality inspection is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1 to 3 The concrete limiting device for construction engineering quality inspection in this embodiment includes a concrete quality inspection device 1 and a placement plate 2 set on the concrete quality inspection device 1. Two movable plates 5 are placed on the top surface of the placement plate 2.

[0024] Two clamping plates 6 are placed on opposite sides of the two movable plates 5. Movable grooves 12 are opened on opposite sides of the two movable plates 5. Mounting plates 15 are fixedly connected inside the two movable grooves 12. Telescopic rods 14 are fixedly connected to the front and back of the two mounting plates 15. Two movable blocks 17 are placed inside the two movable grooves 12. Telescopic rods 14 and movable blocks 17 are fixedly connected. Springs 13 are fitted on the outer periphery of the four telescopic rods 14 and are fixedly connected to the mounting plates 15 and movable blocks 17 respectively. The four movable blocks 17 are fixedly connected to the four clamping plates 6 respectively.

[0025] The movable block 17 and the movable groove 12 are slidably connected, the clamping plate 6 and the placement plate 2 are attached to each other, the telescopic rod 14 is composed of a sleeve and a moving rod, one end of the moving rod passes through and extends into the interior of the sleeve, a limiting block located inside the sleeve is fixedly connected to the outside of the moving rod, and a through hole adapted to the moving rod is opened on one side of the sleeve.

[0026] It should be noted that the concrete quality inspection device 1 is a conventional device known to the public in the existing technology, and its specific structure and working principle will not be described in detail in this article.

[0027] Specifically, pulling the clamping plate 6 causes the moving block 17 to move, which in turn compresses the telescopic rod 14 and the spring 13, causing them to retract. The sliding connection between the moving block 17 and the moving groove 12 supports the clamping plate 6, improving its stability. When the concrete block is placed on the placement plate 2, the clamping plate 6 is released. Under the action of the spring 13, the clamping plate 6 is pushed back to its original position, and the clamping plate 6 and the concrete block fit together, thus restricting the concrete block.

[0028] In this embodiment, the placement plate 2 is equipped with a driving assembly, which includes two driving rods 8. One end of each driving rod 8 is rotatably connected to the opposite side of the fixed plate 9 via bearings, and the other end of each driving rod 8 passes through the two fixed plates 9 respectively. A screw 7 extending into the interior of each driving rod 8 is movably connected to the opposite side of each driving rod 8. The screw 7 is fixedly connected to the moving plate 5. Two positioning slots 3 are opened on the top surface of the placement plate 2, and a positioning block 4 extending into the interior of each positioning slot 3 is fixedly connected to the bottom surface of each of the two moving plates 5.

[0029] Among them, the two drive rods 8 are provided with threaded holes on their opposite sides, the two screws 7 extend into the interior of the two threaded holes and are threadedly connected to them, and the positioning block 4 and the positioning groove 3 are slidably connected.

[0030] Specifically, rotating the drive rod 8 causes it to rotate. Through the threaded connection between the drive rod 8 and the screw 7, and the sliding connection between the positioning block 4 and the positioning groove 3, the screw 7 drives the moving plate 5 to move, and the moving plate 5 fits into the concrete block.

[0031] In this embodiment, a support assembly is provided between the two movable plates 5. The support assembly includes eight rubber pads 16, which are fixedly connected to the top and bottom surfaces of the four movable blocks 17. Limiting grooves 11 are provided on the outer peripheral walls of the two drive rods 8. Two limiting rods 10 are fixedly connected to the top surface of the placement plate 2, with one end extending into the two limiting grooves 11 respectively. The limiting rods 10 and the limiting grooves 11 are in contact.

[0032] Among them, the rubber pad 16 and the moving groove 12 are attached, the limiting groove 11 is an annular groove, and the limiting rod 10 is an elastic rod.

[0033] Specifically, the moving block 17 is supported by the fit between the rubber pad 16 and the moving groove 12, which improves the stability of the moving block 17. After the concrete block is fixed, the limiting rod 10 is pushed and inserted into the limiting groove 11 and fits with it to fix the drive rod 8.

[0034] The working principle of the above embodiments is as follows:

[0035] Pulling the clamping plate 6 causes the moving block 17 to move, which in turn compresses the telescopic rod 14 and spring 13, causing them to retract. The sliding connection between the moving block 17 and the moving groove 12 supports the clamping plate 6, improving its stability. Similarly, the contact between the rubber pad 16 and the moving groove 12 supports the moving block 17, further enhancing its stability. The concrete block is placed on the placement plate 2. Pulling the limiting rod 10 disengages the limiting plate 10 from the limiting groove 11, causing the concrete block to rotate. Drive rod 8 rotates, and through the threaded connection between drive rod 8 and screw 7 and the sliding connection between positioning block 4 and positioning groove 3, screw 7 drives moving plate 5 to move. Moving plate 5 fits against concrete block, clamping plate 6 is released, and clamping plate 6 is pushed back to its original position by spring 13. Clamping plate 6 fits against concrete block, restricting concrete block, and then pushing limit rod 10. Limit rod 10 is reset and inserted into limit groove 11 and fits against it, fixing drive rod 8.
