Description

Technical Field

[0001] The utility model belongs to the technical field of construction safety, in particular to a monitorable pull-up cantilever scaffold. Background Art

[0002] Cantilever scaffolding is widely used in high-rise building construction. Its main function is to support the main structure of the building to avoid collapse during construction, thereby ensuring the safety and quality of the project. During the application of cantilever scaffolding, the vertical load of the frame is transferred to the main structure of the building through the cantilever support structure, thereby ensuring the safety and stability of the cantilever scaffolding. In recent years, due to the frequent safety accidents caused by cantilever scaffolding, it is of great significance to conduct in-depth research on the construction and safety technology of cantilever scaffolding.

[0003] At present, the commonly used cantilever scaffolding is the tie-rod cantilever scaffolding. The use of the tie-rod cantilever scaffolding for construction can avoid the shortcomings of traditional scaffolding construction, improve the scientific nature of various management work on the construction site, and the presence of the tie rod increases the stability and safety of the scaffolding. However, the failure of the tie-rod cantilever scaffolding is usually sudden and catastrophic to construction safety. With the repeated use of the tie rod and the excessive vertical load, it will produce certain deformation and wear, and the upper tie rod end may loosen and slip, which undoubtedly poses a certain safety hazard to high-altitude operations. The current research lacks the real-time monitoring of the tightness of the upper tie rod. Once the tension exceeds the allowable range, the inclined tie rod slips, causing incalculable personnel and property losses. Therefore, it is necessary to design a monitorable tie rod to improve the safety of the cantilever scaffolding. Summary of the invention

[0004] The purpose of the embodiment of the utility model is to provide a monitorable pull-up cantilever scaffold, so as to improve the safety of the cantilever scaffold by monitoring the state of the upper pull rod.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is a monitorable pull-up cantilever scaffold, including a scaffold part and a monitoring system, wherein the scaffold part includes a cantilever steel, which is fixed to the concrete of the bottom floor slab by high-strength bolts and extends outward in the horizontal direction, and buckles are sequentially arranged on the extension section, and movable positioning piles are also arranged on the extension section of the cantilever steel;

[0006] A scaffold body is fixed on the movable positioning pile;

[0007] The embedded parts are arranged on the upper floor slab concrete relative to the floor slab concrete where the cantilever steel section is located;

[0008] The inclined tie rod is assembled by two sections of tie rods through threads, and an adjustable flange is arranged at the connection. The upper end of the first section of the inclined tie rod is connected to the embedded part, and the lower end of the second section is connected to the buckle arranged on the cantilever steel extension section; an adjustable flange is arranged at the connection between the external thread of the first section and the external thread of the second section; a monitoring system is also arranged on the inclined tie rod.

[0009] Furthermore, the monitoring system includes a first sensor disposed at the external thread of the first rod section of the inclined tie rod, a second sensor disposed at the external thread of the second rod section of the inclined tie rod, and a transducer and a data collector disposed on the adjustable flange;

[0010] The transducer is connected to the first sensor and the second sensor signals; the data collector is connected to the first sensor and the second sensor signals; the data collector is also connected to the external information processing terminal signals.

[0011] Furthermore, the first sensor and the second sensor are provided on the inclined rod and are wrapped with a protective cover on the outside.

[0012] Furthermore, the specific types of the sensor and transducer include PZT piezoelectric ceramic patches, and the transducer is pasted with epoxy resin at the intersection of the adjustable flange and the first and second rod sections of the inclined rod.

[0013] Furthermore, the sensor type includes a LORA wireless data acquisition system.

[0014] Furthermore, the external information processing terminal includes a computer and an audible and visual alarm device.

[0015] The beneficial effects of the utility model are:

[0016] 1. When the bolts and the two rod ends are too loose or slip, the transducer generates a wave signal, which is transmitted to the sensors of the two rod sections of the upper pull rod through the flange and the upper pull rod section. The sensor converts the wave signal into an electrical signal. The data acquisition system is used to capture and sample the signal, and finally the sampled signal is processed and analyzed by the computer. Compared with the normal state of the scaffolding upper pull rod, when the flange and the rod section are loose or slip, the signal energy received by the information processing terminal will be lost, thereby playing a monitoring effect on the safety status of the upper pull rod, allowing on-site staff to repair in time, eliminate safety hazards, and avoid casualties and property losses.

[0017] 2. When the diagonal tie rod is subjected to a large tensile force, the adjustable flange and rod section of the diagonal tie rod are prone to loosening. The computer terminal will monitor it in time, and the workers on the construction site can adjust the hanging point position of the diagonal tie rod and the cantilever steel to restore the entire structure to a safe state. When the cross-sections of the upper and lower layers of the building structure are equal or variable, the force range of the diagonal tie rod can also be reasonably guaranteed, thereby expanding the application range of the diagonal tie rod.
