Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building construction, and in particular relates to a cable-sash curtain wall deformation monitoring method. BACKGROUND

[0002] The curtain wall, also known as architectural curtain wall or veil wall, is a light wall with decorative effect commonly used in modern large and high-rise buildings, which is generally composed of metal, glass, stone and artificial board materials, and is installed on the outermost layer of the building, and has the functions of wall, beauty, windproof, rainproof, energy saving, etc. The curtain wall does not bear any structural load, and only bears the self-weight and wind pressure with the structural plate or column.

[0003] The cable-sash point connection full glass curtain wall is a full glass curtain wall in which the glass panel is fixed on the cable frame by a steel claw. It is composed of three parts: glass panel, cable frame and anchor structure.

[0004] The glass panel is fixed by the steel claw installed on the cable frame, and after the caulking treatment, the curtain wall system is finally formed. The glass panel, cable frame and anchor structure form the curtain wall system. The three are interdependent, mutually restricted and mutually influenced. The cable frame is suspended on the anchor structure for tensioning, so as to form a frame with fixed shape and rigidity. Therefore, in addition to bearing the main structure load (self-weight, live load, wind load, snow load and earthquake action), the anchor structure also bears the pre-tension of the cable frame and the tension (counter-thrust) generated after the cable frame is loaded. Moreover, the tension is quite large, and its effect sometimes even exceeds the effect of the load (action). If the anchor structure supporting the cable frame is not considered in the design of the main structure of the building, the cable-sash point connection glass curtain wall cannot be used (rigid frame is used instead), or the main structure must be reinforced (which may affect the architectural effect), and meanwhile, the deflection (displacement) of the anchor structure during construction and use also affects the cable frame and the panel, affects the effective pre-stress value (pre-stress loss value) of the cable frame and the shape of the cable frame, and thus affects the position and effect of the panel. The rigidity of the panel also affects the rigidity and stability of the cable frame.

[0005] At present, in the long-term use of the curtain wall, the cable is always under stress, and in the case of long-term use, the curtain wall is prone to deformation. When the curtain wall deforms greatly, the curtain wall is damaged or even collapses, which poses a safety hazard. SUMMARY

[0006] Therefore, the present application provides a cable-sash curtain wall deformation monitoring method, which can solve the problem of safety hazard caused by the curtain wall deformation in the case of long-term use.

[0007] The present application is implemented as follows:

[0008] The application provides a cable-sash curtain deformation monitoring method.

[0009] S1: fixing a reinforcing device at a glass joint;

[0010] S2: an angle adjusting mechanism is mounted on each reinforcing device, and a radar detector is fixed on the angle adjusting mechanism; the angle adjusting mechanism can drive the radar detector to rotate at multiple angles;

[0011] S3: the radar detector monitors distance data at different angles in real time and transmits the data to an upper computer;

[0012] S4: the upper computer analyzes the data and performs real-time monitoring.

[0013] Based on the above technical solution, the cable-sash curtain deformation monitoring method can be further improved as follows:

[0014] In the S1, the reinforcing device has a support frame, a plurality of fixed steel columns are oppositely arranged around the edges of the support frame, a plurality of cables are arranged on the fixed steel columns, the plurality of cables are arranged staggeredly between each pair of opposite fixed steel columns, the cables pass through a pull rod, a chuck is arranged at the front end of the pull rod, spring sheets and glass claws are arranged on the chuck, the glass claws are detachably fixedly connected with the curtain, and a circular hole for assembling the glass claws is formed in each corner of each unit of the curtain.

[0015] The beneficial effects of the above improvement scheme are that the spring sheets are arranged to enable the curtain to transfer the impact force to the spring sheets when the curtain is impacted, thereby ensuring the stability of the curtain.

[0016] Further, the angle adjusting mechanism comprises a rotating shaft and a rotating block, the rotating shaft is fixed above the pull rod in a threaded manner, the rotating shaft is movably connected with the rotating block, the side surface of the rotating block is fixed with a radar detector, and the radar detector is electrically connected with the upper computer.

[0017] The beneficial effects of the above improvement scheme are that the rotating shaft and the rotating block are arranged to enable the radar detector to rotate by 360 degrees and to enable the radar detector to take pictures at multiple angles, thereby ensuring that each direction can be monitored in real time.

[0018] Further, the bottom of the fixed steel column is provided with a square buffer block.

[0019] Further, the spring sheets and the glass claws are connected with the chuck through hinges.

[0020] Further, the top of the pull rod is provided with circular holes perpendicular to each other, and the diameters of the circular holes are greater than the diameter of the cable.

[0021] Among them, the specific steps of S4 include:

[0022] The first step is to preprocess the real-time data monitored by the radar detectors and classify the real-time data into a distance dataset and an angle dataset between two radar detectors at different time intervals, as well as a curtain wall bending deformation dataset.

[0023] Step 2: Use convolutional networks to establish a cable curtain wall deformation monitoring model;

[0024] Step 3: Use the curtain wall real-time dataset as input data and the distance dataset and angle deflection dataset as output data to optimize the cable curtain wall detection model;

[0025] Step 4: Input the real-time monitoring data of the curtain wall to be tested into the optimized cable curtain wall deformation monitoring model for calculation;

[0026] Step 5: The cable curtain wall deformation monitoring model takes the distance data and angle data between the two radar detectors as output results.

[0027] Furthermore, when the output distance data and the angle data deviate by more than 5% from the distance data and the angle data output last time, the curtain wall is deformed.

[0028] The cable curtain wall deformation monitoring model includes 1 input layer, 3 convolutional layers, 3 Relu nonlinear activation layers, 3 pooling layers, 1 fully connected layer and 1 output layer.

[0029] Wherein, the radar detector is fixed on the rotating block by gluing.

[0030] Compared with the existing technology, the beneficial effect of the cable curtain wall deformation monitoring method provided by the present invention is that it can monitor the deformation of the curtain wall in real time during the use of the glass curtain wall. At the same time, it can calculate data through the cable curtain wall deformation monitoring model to quickly determine whether there is deformation, which greatly reduces safety hazards.
