[0002] In the field of construction engineering, the mechanical properties of concrete directly determine the safety and durability of the project. According to the national standard GB / T50081-2019, a standard concrete test block is usually made by using a 150mmx150mmx150mm cubic test mold box to ensure that the test sample block is formed under standard curing and to provide compliant concrete test sample blocks for subsequent testing.

[0003] However, the existing concrete test sample mold has the following defects: the fixed cubic structure of the traditional test sample mold causes demolding difficulty, the test mold box only has an upper end opening, and the formed test sample block will be attracted to the mold cavity, so it cannot be directly poured out. Therefore, during demolding, it is usually necessary to use a hammer to knock, inject gas at the bottom of the box, etc. However, the operation efficiency of these methods is not high, and the operation is complicated and laborious.

[0004] In summary, the current test sample mold has obvious deficiencies in demolding convenience, which seriously restricts the use efficiency. Therefore, it is necessary to consider how to improve the problem of inconvenient demolding in the later stage. In view of this, we propose a concrete test sample mold. SUMMARY

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-11The present invention will describe the above technical solution in detail through the following embodiments: In this embodiment, the concrete sample mold is as follows: Figures 1-3 As shown, the mold body includes a bottom mold base 2 on which side templates 3 are rotatably installed around the perimeter via hinges 23. In order to facilitate disassembly of the mold body, the main body of the concrete sample block 1 formed inside is exposed to the outside for easy demolding.

[0021] Specifically, such as Figures 4-7 As shown in the structure, in this embodiment, when the four side templates 3 and the bottom mold base 2 are closed, four sample cavities 9 for filling concrete to prepare concrete sample blocks 1 can be formed; the bottom mold base 2 includes a bottom plate 21 with a limiting annular protrusion 22 on its upper surface, and a middle protrusion 25 vertically connected at the center of the bottom plate 21. Triangular partitions 24 distributed in a cross shape are provided around the middle protrusion 25. It should be noted that, as Figure 7 As shown, after the mold is opened, the bottom mold base 2, compared with the traditional cube mold, can reduce the contact area of ​​the concrete sample block 1 from five contact surfaces to two contact surfaces, and has an exposed structure that makes it easy for workers to grab and demold, which facilitates the demolding operation.

[0022] Simultaneously, side template 3, as Figures 4-6 The structure shown includes a vertical plate 32 with a triangular pressure plate 31 fixedly installed on its inner side. To improve the sealing performance of the mold closure, this embodiment provides a protrusion 311 and a sealing groove 241 for clamping and sealing on the closing surfaces of the triangular pressure plate 31 and the triangular partition plate 24, respectively. In this embodiment, the protrusion 311 is made of rubber sealing strip. The vertical plate 32 is rotatably connected to the outer edge of the limiting annular protrusion 22 by a hinge 23. The outer end of the limiting annular protrusion 22 and the inner bottom end of the vertical plate 32 are respectively provided with a first inclined pressure surface 221 and a second inclined pressure surface 321 for fitting and sealing. That is, after closure, four sample cavities 9 are formed, and the sealing structure design only has four splicing seams, which significantly reduces the eight splicing seams for the detachable unfoldable cubic mold, which is conducive to maintaining good sealing quality.

[0023] In order to achieve synchronous closing and consistent locking during closing, the locking part includes four locking components 4 centrally and symmetrically installed on the central convex plate 25, and a locking block 33 is fixedly installed at the upper end of the triangular pressure plate 31.

[0024] Specifically, such as Figures 8-11As shown in the structure, four locking components 4 are fixedly mounted on the middle protruding plate 25 by an L-shaped mounting bracket 41. A toggle block 42 is rotatably mounted on the lug 411 of the L-shaped mounting bracket 41 via a rotating shaft block 421. In order to achieve the effect of tightening the locking components 4 when pressed down, a connecting plate 44 is rotatably mounted on the toggle block 42 and located outside the rotating shaft block 421 via a rotating rod 43. A locking plate 45 with a slot 451 is rotatably mounted on the other end of the connecting plate 44 and is snapped onto the locking block 33 to achieve locking and fixation.

[0025] Because the four side templates 3 provided around the perimeter of this application need to be locked and closed synchronously with the bottom mold base 2 in order to obtain a consistent sealing and molding effect and assembly and disassembly efficiency; therefore, in this embodiment, a threaded rod 5 is vertically installed at the center of the middle convex plate 25, and a spring 6 and two trays 7 are sequentially installed above the threaded rod 5, and a handwheel 8 is threadedly installed.

[0026] A force-bearing end 422 is provided at the outer end of the actuating block 42, located between two trays 7. Rotating the handwheel 8 presses down the tray 7, causing the force-bearing end 422 to press down, which drives the four locking components 4 to tighten synchronously. When demolding is required, the handwheel 8 is rotated in the opposite direction to release it. Under the action of the spring 6, the tray 7 lifts the force-bearing end 422 in the opposite direction, causing the locking components 4 to open synchronously, thus realizing the function of rapid demolding. Before pouring concrete, the workers usually apply lubricating oil to the sample cavity 9. This part is existing technology. Therefore, when the mold is opened, the concrete sample block 1 in the sample cavity 9 can be directly taken out. Compared with the existing cubic box mold, this application can demold efficiently and clean the sample cavity 9 of the mold.

[0027] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
