Description

Technical Field

[0001] The utility model relates to the technical field of building material detection, in particular to a building material strength detection device. Background Art

[0002] The strength of building materials has an important impact on the structural quality of buildings. For example, the strength of concrete materials, steel bars, and steel structural member materials used in construction projects need to be inspected by comprehensive testing or sampling testing before installation and use to ensure that the material quality meets the requirements. At present, the strength test of building materials mainly relies on pressure testing machines, which apply continuous pressure to the material and calculate the strength of the material through the microcomputer receiving the pressure value changes and the corresponding deformation of the material.

[0003] When current pressure testing machines for building materials are used to test the strength of building materials, brittle building materials such as concrete test blocks and mortar blocks often break and fly due to continuous pressure, causing personal injury to testers. Therefore, a protective cover is needed to seal the open part of the pressure testing machine during the test. However, this traditional protective cover needs to be repeatedly removed from and installed in the testing machine before and after the test, which is inconvenient to use.

[0004] Therefore, in view of the fact that the protective cover used in the above-mentioned existing building material strength testing pressure testing machine has a simple structure and is inconvenient to use due to frequent taking and placing, a testing device with a protective structure that can quickly open and close the testing machine opening can be designed to ensure the safety of the test while improving the operating experience and efficiency. Utility Model Content

[0005] In order to overcome the problem that the protective cover used in the existing building material strength testing pressure testing machine has a simple structure and is inconvenient to use due to frequent removal and placement.

[0006] The technical solution of the utility model is: a building material strength testing device, including a frame, a loading platform, connecting columns, buckles, a connecting frame, a beam, a protective plate, and a magnetic fixing; the frame is a door-shaped frame structure open at the front and back, and the loading platform is vertically lifted and lowered along the tracks on the left and right sides of the frame to adjust the building material test height, the upper surface of the loading platform structure is fixedly connected with two front and back symmetrical connecting columns, two buckles are respectively snap-connected to the corresponding connecting columns, and the outer wall of each buckle is fixedly connected with a beam for embedded installation of LED lamps, the two beams are respectively located at the front and back sides of the frame, and a protective plate of Saigang material is installed on the beam through a rotating connector, and a counterweight structure is provided at the lower end of the protective plate.

[0007] Preferably, the crossbeam is quickly fixed to the loading platform through a snap connection between a buckle ring and a connecting column, and is equipped with an open protective plate of a rotating opening and closing frame to seal the open area where the building materials are inspected, thereby preventing the material from splashing and causing personal injury to the inspectors.

[0008] Preferably, longitudinal through openings are provided on both the front and rear sides of the loading platform, a slot is provided in the middle of the connecting frame and the slot is located above the opening, spring pins are inserted into the opening and the corresponding slot, and after the spring pins are inserted into the opening and the corresponding slot, the connecting frame is locked on the loading platform to prevent the buckle with a notch on the outer edge from being detached from the connecting column due to the impact force of the collapsed building materials.

[0009] Preferably, the spring pin is composed of a pin, a pier head and a spring. The spring is fixedly connected between the pier head at the lower end of the pin and the lower surface of the loading platform and is sleeved on the outside of the pin. The elastic contraction characteristics of the spring are utilized to pull the pier head upward, so that the pin is automatically pushed into the through hole and the corresponding slot. The locking is convenient and quick, and the locking effect is also relatively good.

[0010] Preferably, the rotating connecting member is an axis head and an axis hole. The axis head is fixedly connected to the back side of the cross beam. An axis hole that is sleeved on the axis head is opened in the middle of the lower end of the protective plate. The protective plate rotates around the axis head. When rotated vertically, the openings on the front and rear sides of the frame are closed. When rotated horizontally, the construction materials on the loading platform are taken and placed. The rotating connecting member can also use bearings, pins, etc.

[0011] Preferably, a handle is fixedly connected to the lower end of the protective plate, and the counterweight structure is a metal bar embedded in the handle. The lower end of the metal bar has an expanded structure. The user can control the rotation of the protective plate by turning the handle. After releasing the handle, due to the presence of the counterweight structure, the handle will fall due to gravity, causing the protective plate to tend to automatically reset to a vertical position, and with the assistance of manual adjustment, the protective plate can be kept in a vertical state again.

[0012] Preferably, the LED lamp tube is embedded and installed on the opposite side of the beam to illuminate the loading platform. The protective plate is made of transparent steel material. The LED lamp tube is powered by an external AC power supply. During the inspection process, the building materials being inspected in the testing machine can be observed through the protective plate and with the auxiliary lighting of the LED lamp tube.

[0013] Preferably, magnetic strips are installed on the surfaces of the front and rear ends of the frame, and magnetic blocks that can be magnetically adsorbed and fixed to the magnetic strips are symmetrically installed on the left and right sides of the protective plate facing the frame. When the protective plate is flipped to a vertical position, the magnetic blocks are adsorbed on the magnetic strips to prevent it from rotating and falling back, thereby maintaining a safe protection state.

[0014] Beneficial effects of the utility model:

[0015] 1. The stage is used as the carrying structure of the protective plate. With the movement of the stage, the open part of the inspection part of the building materials can be closed synchronously to prevent the material from splashing and causing personal injury to the inspectors. The protective plate opens and closes the opening of the frame by rotating. Compared with the original protective cover used in the set, it does not need to be repeatedly taken and put, which is more convenient to use and simpler to operate;

[0016] 2. The magnetic device installed on the protective plate and the frame can prevent the protective plate from rotating and falling back when the protective plate closes the frame opening, and the protective state is stable;

[0017] 3. With the advantages of high strength and light weight of the protective plate made of transparent Saigang material, it has a good protective effect on collapsed building materials, and it is convenient to observe the inside of the testing machine through it.
