Problems solved by technology

[0002] Scaffolding is widely used in the fields of construction, industry, shipbuilding, etc. Among them, steel pipes (outer diameter φ48) are the most used. It is simple, flexible and convenient to build scaffolding and formwork with steel pipes, and the steel pipes are durable and low in cost. Fasteners are needed to connect the scaffolding or formwork, and the joints are hinged, which makes the stability of the steel pipe support structure poor. If the stability of the support structure is not given enough attention, there will be safety hazards in the construction plan and erection process. , which may cause a collapse accident
[0003] Existing scaffolding or formwork support is generally built according to the prior design or national and industry standards. There are no problems on the surface, but in actual work, there are many problems. For example, the wall thickness of steel pipes has been reduced due to long-term use or corrosion Thinning, the steel pipe itself is in a bent state, the quality of the fasteners used is unqualified, the quality of the front-line operators is low, and the operation is not standardized, etc., so that there are potential safety hazards in the construction of scaffolding or formwork, and it cannot be monitored in subsequent operations. , resulting in a safety accident
If all steel pipes or some steel pipes at key positions have self-stress monitoring function, accidents will be avoided or greatly reduced. However, such products have not yet been launched

Embodiment 1

[0042] Such as figure 1 , 2 A scaffolding smart steel pipe with self-stress monitoring shown in and 3 includes a steel pipe 8, an optical fiber bending sensor unit arranged inside the steel pipe 8, a battery module 24 for supplying power to the optical fiber bending sensor unit, and a battery module located outside the steel pipe 8. And away from the control unit 101 of the steel pipe 8, the optical fiber bending sensing unit includes a curved test channel through which the signal optical fiber 33 passes, and the signal optical fiber 33 is connected to the signal optical fiber 33 and changes the optical signal power in the signal optical fiber 33. A test processing unit 5 for synchronous testing and analysis processing. The test processing unit 5 is also connected to a wireless transceiver module 25 and an alarm module 23 in the form of sound or vibration. The alarm module 23 is located inside the steel pipe 8. The processing unit 5 is also connected to the battery module 24, an...

Embodiment 2

[0049] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the curved support 10 is a spring 38, and a plurality of deforming teeth 4-1 and a plurality of deforming teeth 4-2 are arranged correspondingly in the spring 38 and adjacent to each other. Between the coils of spring wires, deformed tooth 4-1 and deformed tooth 2 4-2 are arranged alternately. In this embodiment, the structure, connection relationship and working principle of the remaining parts are the same as those in the first embodiment.

Embodiment 3

[0051] Such as Figure 5 with 6 As shown, the difference between this embodiment and Embodiment 1 is that the curved support 10 is a corrugated tube 40, and the deforming tooth 4-1 and the deforming tooth 2 4-2 are correspondingly arranged on the tube wall 42 of the corrugated tube 40 On the two opposite sides of the recess, deformed tooth 4-1 and deformed tooth 2 4-2 are arranged alternately. In this embodiment, the structure, connection relationship and working principle of the remaining parts are the same as those in the first embodiment.

Abstract

The invention discloses a scaffold intelligent steel pipe with a self-stress-monitoring function. The scaffold intelligent steel pipe comprises a steel pipe, an optical fiber bending sensing unit, a battery module and a control unit, wherein the optical fiber bending sensing unit comprises a curve-shaped testing channel through which a signal optical fiber can pass and a testing processing unit, the testing processing unit is further connected with a wireless transceiving unit I and an alarm module I, the testing processing unit is further connected with the battery module, and the wireless transceiving unit I is connected with the alarm module I; the curve-shaped testing channel comprises a curve-shaped support, as well as a plurality of deformation teeth I and a plurality of deformation teeth II, which are continuously distributed on the two opposite sides of the curve-shaped support, and a curve-shaped channel I through which the signal optical fiber can pass is formed between the head parts of the plurality of the deformation teeth I and the plurality of the deformation teeth I; and the control unit comprises a wireless transceiving module II and a alarm module II, as well as a control module and a display module. The scaffold intelligent steel pipe disclosed by the invention has the advantages of reasonable design, good using effect and capabilities of effectively realizing monitoring of changes in stress of a scaffold during the using process and avoiding the occurrence of safety accidents.

Description

Technical field [0001] The invention relates to a scaffold steel pipe, in particular to a scaffold smart steel pipe with self-stress monitoring. Background technique [0002] Scaffolding is widely used in construction, industry, shipbuilding and other fields. Among them, steel pipes (outer diameter φ48) are used the most. It is simple, flexible and convenient to build scaffolding and formwork with steel pipes, and the steel pipes are durable and low in cost. Both scaffolding and formwork support need to be connected by fasteners. The nodes are hinged, which makes the stability of the steel pipe support structure poor. If the stability of the support structure is not paid enough attention, there will be safety risks in the construction plan and erection process. , Which may cause a collapse accident. [0003] The existing scaffolding or formwork is generally constructed in accordance with the prior design or national and industry standards. On the surface, there is no problem, but ...
