Description

Technical Field

[0001] This utility model relates to the field of building concrete technology, and in particular to a device for testing the compressive strength of building concrete components. Background Technology

[0002] Concrete is one of the most commonly used materials in construction engineering, and its compressive strength is a key indicator of concrete quality, directly related to the safety and stability of building structures. From residential buildings to infrastructure construction such as bridges and roads, concrete components are used extensively. If the compressive strength of concrete fails to meet standards, it can lead to serious safety accidents such as cracks, deformation, or even collapse of the building structure. Therefore, compressive strength testing devices are needed.

[0003] Existing testing devices for the compressive strength of concrete building components typically focus on pressure application and data measurement in their structural design, with insufficient consideration given to protection when the component fails under compressive stress. When a concrete component undergoes brittle failure under ultimate pressure, the broken concrete fragments will fly at high speed, and most testing devices lack effective protective structures to contain the flying fragments, exposing testing personnel to danger. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that when concrete components undergo brittle failure under ultimate pressure, the broken concrete fragments fly off at high speed, and most testing devices lack effective protective structures to restrain the flying fragments, thus exposing the testing personnel to danger. Therefore, this invention proposes a device for testing the compressive strength of building concrete components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for testing the compressive strength of building concrete components, comprising a U-shaped body, a hydraulic cylinder fixedly connected to the top inner wall of the U-shaped body, a pressing disc fixedly connected to the output end of the hydraulic cylinder, vertical rods fixedly connected to the interior of the U-shaped body near the four corners, limiting components being sleeved and slidably connected to the surface of each vertical rod, the limiting components being fixedly connected to the pressing disc, a sliding hole being opened inside one side inner wall of the U-shaped body, a lifting plate being embedded and slidably connected inside the sliding hole, a screw threaded through and connected to the center of the lifting plate, U-shaped protective plates fixedly connected to both ends of the lifting plate, and a pressure sensor embedded and fixedly connected to the bottom inner wall of the U-shaped body.

[0006] Preferably, the bottom of the U-shaped body and near the four corners are all fixedly connected to support legs, and the support legs are trapezoidal in shape.

[0007] Preferably, the bottom of the screw is rotatably connected to the inner wall bearing at the bottom of the sliding hole, and the top of the screw penetrates the inner wall at the top of the sliding hole and is rotatably connected to its bearing.

[0008] Preferably, a drive motor is fixedly connected to the top of the U-shaped body, and the output end of the drive motor is fixedly connected to the top of the screw.

[0009] Preferably, the surface of the lifting plate is slidably connected with a limiting rod, and the two ends of the limiting rod are fixedly connected to the top and bottom inner walls of the sliding hole, respectively.

[0010] Preferably, a display screen and a control panel are fixedly connected to the surface of the U-shaped body, and a storage battery and a controller are embedded and fixedly connected inside the U-shaped body and located on one side of the sliding hole.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, during testing, the screw can be driven by a drive motor to rotate. The rotation of the screw can drive the lifting plate to descend, and the descent of the lifting plate can drive the U-shaped protective plate to descend, which can cover the testing area. This can prevent the concrete components of the building from being damaged or collapsing during the testing process, thereby improving the safety of the testing personnel.

[0013] 2. In this utility model, the vertical rod, limiting component, and limiting rod, while ensuring the normal operation of components such as the extrusion disc, limit their movement to prevent abnormal displacement of components under the impact of component collapse, thus ensuring the overall structural stability of the device and indirectly protecting the safety of testing personnel.

This allows the hydraulic cylinder 4 to push the extrusion plate 5 down to extrude the building concrete components for compressive strength testing. Vertical rods 3 are fixedly connected to the inside of the U-shaped machine body 1 near the four corners. Limiting components 6 are fitted and slidably connected to the surface of each vertical rod 3.

[0024] The overall effect of Embodiment 2 is as follows: Support legs 2, which are trapezoidal in shape, are fixedly connected to the bottom of the U-shaped body 1 near its four corners, thus supporting the bottom of the U-shaped body 1; the bottom of the screw 8 is rotatably connected to the bearing on the bottom inner wall of the sliding hole 7, and the top of the screw 8 penetrates the top inner wall of the sliding hole 7 and is rotatably connected to its bearing, thus limiting the movement of both ends of the screw 8; a drive motor 11 is fixedly connected to the top of the U-shaped body 1, and the output end of the drive motor 11 is fixedly connected to the top of the screw 8.
