With the increasing development of my country's economic construction, structures in construction engineering, municipal engineering and other fields are springing up like bamboo shoots after rain. School corridors, residential balconies, pedestrian bridges, exhibition halls and other structures need to be equipped with enclosure structures such as railings, railings, and handrails. These enclosure structures not only enhance the aesthetics of the building, but also protect personal safety, so they are required to have sufficient rigidity to make them deform less under the action of horizontal thrust.

With the extensive use of enclosure structures such as railings, relevant technical personnel and university scholars have conducted research on railing design, construction, and testing. Among them, detection is the last guarantee measure before the railing is put into use. In order to protect people's life safety, it is particularly important to carry out on-site detection technology research on railings and other enclosure structures.

Existing inventions and creations usually apply horizontal thrust to the railings, which are complicated in equipment, difficult to operate, and have limitations on site conditions. For example, in patent CN105699188A, a set of thrust detection devices composed of horizontal beams, jacks, and mobile trolleys is used to detect the horizontal thrust of railings, but it requires walls to provide reaction force for beams, which cannot be applied to pedestrian bridges and other conditions without walls. on-site testing. A similar situation exists in the patent CN103134700A, which is an on-site detection device composed of an oil pump, a reaction beam, a reaction column, and a displacement meter. This device is only applicable to buildings with reaction walls such as corridors and balconies. on-site testing.
