[0001] The utility model relates to the technical field of concrete shear walls, in particular to a concrete shear wall cross-section size control and early warning device. Background Art

[0002] With the continuous promotion of prefabricated building policies and the improvement of market acceptance, prefabricated buildings are currently developing in full swing. Enterprises in various regions are competing to develop prefabricated buildings, and various prefabricated building structural systems have emerged, showing a trend of a hundred schools of thought. Prefabricated shear wall structure is a type of prefabricated concrete structure, which is defined as a prefabricated concrete structure in which the main load-bearing components, shear walls, beams, and slabs, are partially or completely composed of prefabricated concrete components.

[0003] During the pouring of concrete shear walls, tension screws are required to fix the position of the shear wall formwork to ensure the cross-sectional size of the shear wall. When the concrete shear wall is poured, the continuous vibration of the vibrating rod, especially when the vibrating rod touches the tension screw, will cause the fastening nut to slowly loosen and back out, causing the shear wall formwork to bulge, resulting in an increase in the cross-sectional size of the shear wall and quality problems of the shear wall. Summary of the invention

[0004] The purpose of the utility model is to solve the problem that the fastening nuts on the surfaces of the two internal tension screws of the shear wall in the above-mentioned background technology may loosen and back out during the fixing process, thereby causing the subsequent shear wall formwork to expand, resulting in an increase in the cross-sectional size of the shear wall and problems with the quality of the shear wall, and a concrete shear wall cross-sectional size control and early warning device is proposed.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A concrete shear wall cross-sectional size control and early warning device comprises a shear wall formwork, a tension screw rod is inserted into the shear wall formwork, fastening nuts are threadedly connected at both ends of the tension screw rod, and an early warning nut is arranged at the outer end of the fastening nut, wherein the early warning nut comprises:

[0007] The mounting nut is threadedly connected to the surface of the tension screw rod, and a force sensor is arranged on a side of the mounting nut close to the fastening nut;

[0008] A plurality of setting grooves are arranged on a side of the mounting nut away from the force sensor, and a resisting plate is rotatably arranged in the setting groove.

[0009] As a further solution of the utility model: a rotating shaft is rotatably arranged in each setting groove, a resistance plate is fixedly arranged on the surface of the rotating shaft, and an end of the resistance plate away from the rotating shaft is arranged as an inclined surface.

[0010] As a further solution of the utility model: the bottom surface of each setting groove is set as an inclined surface.

[0011] As a further solution of the utility model: a plurality of setting grooves are arranged in a circular array with equal distances about the central axis of the mounting nut.

[0012] As a further solution of the utility model: vertical wooden beams are arranged on the outer side of the shear wall formwork.

[0013] As a further solution of the utility model: two reinforcement brackets are arranged at both ends of the tension screw rod, and the reinforcement brackets are in contact with one side of the vertical wooden beam.

[0014] As a further solution of the utility model: a contact cover is arranged between the fastening nut and the reinforcement bracket.

[0015] Beneficial effects of the utility model:

[0016] (1) The utility model provides a concrete shear wall cross-sectional dimension control warning device. By setting a warning nut, when the fastening nut on the surface of the tension screw is stripped, it will trigger the force sensor on the back of the wireless intelligent warning nut, and the warning nut will start the warning, so that the hidden risk point of the fastening nut loosening can be visualized and the position of the loose nut can be accurately located;

[0017] (2) The utility model is a concrete shear wall cross-sectional dimension control warning device. By setting a rotating shaft and a contact plate, after the warning nut is installed at the specified position, the contact plate is rotated through the rotating shaft, so that one end of the contact plate is rotated to the surface of the tension screw, so that one end of the contact plate contacts the raised thread on the surface of the tension screw, and the contact plate reinforces and fixes the position of the predetermined nut. To prevent the warning nut from loosening, there is a gap between the warning screw force sensor and the fastening screw after loosening, thereby giving the fastening screw space to loosen the wire and avoid the warning nut from being unable to detect in time after the fastening nut loosens the wire.

The early warning nut 4 includes a mounting nut 42, and a threaded hole 43 is provided at the center of the mounting nut 42, and the mounting nut 42 is threadedly connected to the surface of the tension screw 2 through the threaded hole 43. A force sensor 41 is provided on the side of the mounting nut 42 close to the fastening nut 3, and the force sensor 41 is communicatively connected with an external monitoring device.
