Description

Technical Field

[0001] The utility model relates to the technical field of pressure resistance detection devices, in particular to a pressure resistance detection device for civil engineering materials. Background Art

[0002] In the process of civil engineering construction, building formwork is generally used. Building formwork is a temporary support structure, which is made according to the design requirements to shape the concrete structure and components according to the specified position and geometric dimensions, maintain its correct position, and bear the deadweight of the building formwork and the external load acting on it. The building formwork needs to be tested for pressure resistance during use to ensure that its quality meets the standards. The existing detection devices are relatively complex. At the same time, the building formwork to be tested is generally stable during the detection process, and it is easy to slip, which poses a safety hazard, thereby affecting the detection effect of the building formwork. In order to solve the above technical problems, the patent document with announcement number CN 215525329 U discloses a pressure resistance detection device for civil engineering material experiments.

[0003] However, when it is used, the template will be damaged after extrusion, and some materials of the damaged template will fall into the groove where the movable seat moves on the base, and then be stuck by the bidirectional screw and the base arranged on the lower side of the groove, resulting in the inability to clean up the fallen damaged materials and causing damage to the bidirectional screw. Utility Model Content

[0004] The utility model mainly provides a pressure-resistant detection device for civil engineering materials, which solves the problem in the prior art that some materials of the squeezed and damaged template will fall into the groove in which the movable seat moves on the base, and are thus stuck by the bidirectional screw and the base arranged on the lower side of the groove, resulting in the inability to properly clean the fallen damaged materials and causing damage to the bidirectional screw.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A pressure-resistant testing device for civil engineering materials includes a base, a first motor, a bidirectional screw, a movable seat, a second extrusion mechanism, a second pressure plate, a guide rod and a screw rod; a displacement groove is provided on the base, a mounting platform is provided on the base corresponding to the middle of the displacement groove, a placement platform is provided in the displacement groove corresponding to the position above the mounting platform, a guide member matching the mounting platform is provided on the lower side of the placement platform, and a plurality of support rods are provided on the lower side of the placement platform; a first bracket and a second bracket are provided on the base corresponding to the front and rear sides of the displacement groove, respectively, a bidirectional screw is rotatably connected to the first bracket, a first guide rod is provided on the second bracket, a movable seat is symmetrically threadedly connected to the bidirectional screw, and the movable seat is slidably connected to the base. Among them, components such as the base, the first motor, the bidirectional screw, the movable seat, the second extrusion mechanism, the second pressure plate, the guide rod and the screw rod and some other functional components that realize the overall function can adopt the existing technology, and this application is mainly to improve the defects of the existing technology. When in use, the bidirectional screw is driven to rotate by the first motor, thereby driving the moving seat to move in coordination with the first guide rod, so that the template placed on the placement table is tested for pressure resistance in coordination with other functional components, and then the template is tested for pressure resistance from top to bottom by the second extrusion mechanism and the corresponding functional components. At this time, the placement table can be guided downward by the guide member and supported by the support rod. The structure of the present application is adopted, and the bidirectional screw and the first guide rod are arranged on both sides of the displacement groove, so as to avoid the bidirectional screw in the middle of the displacement groove causing the damaged material under the template to be squeezed and stuck on the lower side edge of the bidirectional screw and the displacement groove. At the same time, the structure can clean the damaged material on the placement table after the test and drop it to the ground through the displacement groove; and by setting the placement table and the support rod on the lower side of the placement table, the placement table and the template thereon can be effectively supported, thereby preventing the base from being deformed or damaged when being extruded from top to bottom by the second extrusion mechanism and the corresponding functional components.

[0007] Furthermore, the guide member includes a second guide rod disposed at the lower side of the placement table; a second guide hole matching the second guide rod is provided on the mounting table. With this structure, when the support rod has not yet touched the ground, the placement table is limited and guided by the second guide rod, and well supported by the support rod, and the second guide rod matches the second guide hole to facilitate the disassembly and assembly of the placement table.

[0008] Furthermore, the lower end of the support rod is detachably connected to a support base. With this structure, the support area of ​​the lower end of the support rod can be increased, thereby providing better support.

[0009] Furthermore, the base is provided with a fence, the guide rod is slidably connected with an upper cover, the upper cover is provided with a through hole matching the screw rod, and also includes a spring with two ends respectively provided on the upper cover and the second pressure plate. With this structure, a protective structure can be formed by the fence and the upper cover, thereby making the detection safer, and the setting of the spring can make the upper cover more closely fit the upper side of the fence when it falls without affecting the continued movement of the guide rod, and the protective effect is better.

[0010] Furthermore, the enclosure and the upper cover are both made of transparent materials, which makes it easier to observe during inspection.

[0011] Beneficial effect: With the structure of the present application, the bidirectional screw and the first guide rod are arranged on both sides of the displacement groove, thereby preventing the bidirectional screw from causing the damaged material under the template to be squeezed and stuck on the lower side edge of the bidirectional screw and the displacement groove in the middle of the displacement groove. At the same time, the structure can clean up the damaged material on the placement table after detection and drop it to the ground through the displacement groove; and by setting up a placement table and supporting rods on the lower side of the placement table, the placement table and the template thereon can be effectively supported, thereby preventing the base from being deformed or damaged when extruding from top to bottom through the second extrusion mechanism and the corresponding functional components.
