[0002] Prefabricated buildings are mainly built by mass-producing different structural templates for on-site assembly, thereby realizing the construction of buildings, which can greatly improve the installation efficiency. With the rapid development of prefabricated buildings, people are paying more and more attention to the safety of building components. Among them, the prefabricated floor is the weighing part of the building, and its bearing capacity is related to the stability of the building. For this reason, it is necessary to detect the bearing capacity of the floor through a detection device. The existing floor bearing capacity detection device is a building floor bearing strength detection device with publication number CN214373873U.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 3 The utility model provides a technical solution: a test device for inspecting the bearing capacity of the floor slab of an existing building, comprising a fixed frame 1, the fixed frame 1 is symmetrically connected to a movable frame 2, a vertical rod 3 is vertically fixed on the fixed frame 1, a hydraulic rod 6 is fixed at the center position of the upper end surface of the fixed frame 1, a mounting plate 7 is fixed at the output end of the hydraulic rod 6, a pressure sensor 8 is fixed at the lower end surface of the mounting plate 7, a pressure block 9 is fixed at the lower end of the pressure sensor 8, and a protective cover 10 is arranged on the outer side of the pressure block 9.

[0020] The movable frame 2 is slidably connected to the fixed frame 1, and a support plate 201 is fixed to the movable frame 2; the vertical rod 3 is symmetrical about the center line of the fixed frame 1, and a limit block 301 is fixed to the upper end of the vertical rod 3; a movable block 4 is slidably connected to the vertical rod 3, and the movable block 4 contacts the limit block 301 to achieve a limiting effect; one end of a connecting rod 5 is rotatably connected to the movable block 4, and the other end of the connecting rod 5 rotates on the movable frame 2, and the connecting rod 5 is symmetrically distributed about the center line of the movable block 4; a sliding rod 1001 is also symmetrically fixed to the upper end surface of the protective cover 10, and the sliding rod 1001 penetrates the mounting plate 7 for sliding, and one end of a spring 1002 is also fixed to the protective cover 10, and the other end of the spring 1002 is fixed to the lower end surface of the mounting plate 7;

[0021] When using the existing building floor bearing capacity test device, if Figure 1-Figure 3As shown, firstly, assemble the device with the suspended floor slab, and place the device on the floor slab. At this time, the protective cover 10 contacts the floor slab. Under the action of the gravity of the entire device, the spring 1002 can be forced to contract. With the sliding action of the slide bar 1001, the protective cover 10 can be moved relative to the fixed frame 1 until the pressure block 9 contacts the floor slab. Then, the upper and lower positions of the movable block 4 can be adjusted by the sliding action between the movable block 4 and the vertical rod 3. When the movable block 4 moves upward, the connecting rod 5 is forced to rotate. Through the transmission action of the connecting rod 5, the left and right movable frames 2 can move towards each other, thereby reducing the distance between the two movable frames 2, until the movable frame 2 contacts the side of the floor slab. At this time, the support plate 201 is located at the lower side of the floor slab.

[0022] The center points of the pressing block 9 and the pressure sensor 8 coincide with each other, and the pressing block 9 is made of tungsten steel; the protective cover 10 is slidably connected to the pressing block 9, and the protective cover 10 is made of transparent acrylic material;

[0023] After assembly is completed, during testing, if Figure 1 and Figure 2 As shown, by controlling the extension of the hydraulic rod 6, the pressure block 9 is driven to move. Since the pressure block 9 is in contact with the floor slab, the fixed frame 1 and the movable frame 2 can be forced to move upward, thereby driving the support plate 201 to move upward until the support plate 201 is in contact with the lower end surface of the floor slab. At this time, the hydraulic rod 6 is continued to be controlled to extend. Since the pressure block 9 and the support plate 201 limit the floor slab, the entire device and the floor slab are in a fixed state. When the hydraulic rod 6 continues to extend, the pressure block 9 generates pressure on the floor slab. With the action of the pressure sensor 8, the magnitude of the applied pressure can be detected, thereby realizing the detection of the bearing capacity of the floor slab. In the detection process, when the floor slab breaks, the protective cover 10 can achieve a protective effect at this time, effectively avoiding the splashing of sand and gravel when the floor slab breaks, thereby ensuring the safety of the experiment. According to the above principle, the detection experimental device can be used for detection during the production of the floor slab, and can also be used for detection on site, thereby improving the adaptability of the device. The overall structure is simple and easy to operate, which is suitable for wide promotion. This is the working principle of the test device for the bearing capacity inspection of the floor slab of existing buildings.
