Description

Technical Field

[0001] This utility model relates to a monitoring system for tall formwork. Background Technology

[0002] High-rise formwork support system (hereinafter referred to as high-rise formwork support) refers to concrete formwork support erected at construction sites for buildings and municipal infrastructure with a height of 8m or more, or a span of 18m or more, or a total construction load of 15kN / m2 or more, or a concentrated line load of 20kN / m2 or more.

[0003] To enhance the safety of high-rise formwork construction and process safety control, it is necessary to monitor the high-rise formwork. The monitoring data includes stress analysis of the formwork support uprights (i.e., the uprights of the adjustable supports) to determine the support condition of the formwork support. Current methods typically involve directly placing measuring sensors between the adjustable support plate and the main beam. However, this arrangement requires the installation of measuring sensors in advance during the erection of the adjustable supports, and maintenance (e.g., disassembly and replacement) is difficult after installation. Utility Model Content

[0004] The purpose of this utility model is to provide a monitoring system for tall formwork, including an adjustable support and a measuring sensor. The adjustable support includes an upright, a screw rod inserted into the upright at its lower end, an adjusting nut sleeved on the screw rod and supported on the end of the upright, and a support plate located on the upper end of the screw rod. It also includes a support arm, a secondary screw rod, a secondary adjusting nut, and a secondary support plate. The inner end of the support arm is provided with a fastener that can be detachably fastened to the screw rod. The outer end of the support arm extends radially along the screw rod and is provided with a support sleeve. The lower end of the secondary screw rod passes through the support sleeve in a pluggable manner, and the secondary support plate is located on the upper end of the secondary screw rod. The secondary adjusting nut is sleeved on the secondary screw rod and supported on the support sleeve. The measuring sensor is mounted on the secondary support plate.

[0005] This invention allows for the installation of the measuring sensor after the adjustable support has been installed, eliminating the need for prior installation and improving construction flexibility. Furthermore, the measuring sensor can be maintained via the lifting sub-support plate without affecting the support function of the adjustable support. Attached Figure Description

[0013] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution.

[0014] like Figures 1 to 7 The high-rise formwork monitoring system shown includes an adjustable support and a measuring sensor 100. The adjustable support includes a vertical rod 10, a screw 20 inserted into the vertical rod 10 at its lower end, an adjusting nut 30 sleeved on the screw 10 and supported on the end of the vertical rod 10, and a support plate 40 provided on the upper end of the screw 20. The adjusting nut 30 is threadedly engaged with the screw 20 so that when the adjusting nut 30 rotates, it drives the screw 20 to move up and down. The adjustable support in this embodiment can adopt existing technology (see the national industry standard JGJ / T231-2021 for details). The measuring sensor 100 is a load sensor, stress sensor, or strain sensor.

[0015] It also includes a support arm 50, a secondary screw 60, a secondary adjusting nut 70, and a secondary support plate 80;

[0016] The inner end of the support arm 50 is provided with a fastener 501 that can be detachably fastened to the screw 20; the outer end of the support arm 50 extends radially along the screw 20, and the outer end of the support arm 50 is provided with a support sleeve 502.

[0017] The lower end of the auxiliary screw 60 passes through the support sleeve 502 in a pluggable manner, and the auxiliary support plate 80 is located at the upper end of the auxiliary screw 60;

[0018] The auxiliary adjusting nut 70 is sleeved on the auxiliary screw 60 and supported on the support sleeve 502. The auxiliary adjusting nut 70 is threadedly engaged with the auxiliary screw 60 so that when the auxiliary adjusting nut 70 rotates, it drives the auxiliary screw 60 to move up and down.

[0019] The measuring sensor 100 is mounted on the sub-plate 80.

[0020] This technical solution allows for the installation of the measuring sensor after the adjustable support is installed, eliminating the need for prior installation and improving construction flexibility. Furthermore, the measuring sensor can be maintained via the lifting sub-support plate without affecting the support function of the adjustable support.

[0021] The installation process of this utility model is as follows:

[0022] After the adjustable support completes the installation of the main beam (not shown in the figure), first, put the auxiliary adjusting nut 70 on the outside of the auxiliary screw 60, then insert the auxiliary screw 60 into the support sleeve 502 at the outer end of the support arm 50, and then use the fastener 501 at the inner end of the support arm 50 to install and lock the support arm 50 onto the screw 20. Before locking the fastener 501, the support arm 50 can be adjusted to a suitable position around the screw 20 before locking the fastener 501. By turning the auxiliary adjusting nut 70, the auxiliary screw 60 can be driven to move up and down to adjust the height of the auxiliary support plate 80, and the measuring sensor 100 on the auxiliary support plate 80 can be made to abut against the main beam supported by the adjustable support, thereby making the measuring sensor 100 bear force. The initial force on the measuring sensor 100 can be adjusted by turning the auxiliary adjusting nut 70 to drive the auxiliary screw 60 and the auxiliary support plate 80 on it to move up and down. When the measuring sensor 100 needs maintenance, the auxiliary support plate 80 is lowered by turning the auxiliary adjusting nut 70. The measuring sensor can then be maintained. After maintenance, the auxiliary adjusting nut 70 is turned again to raise the auxiliary support plate 80 until the measuring sensor 100 is under force again.

[0023] The measurement process in this embodiment can be recorded in a list. The table content may include, for example, the initial value of the measuring sensor, the current value recorded at different time periods, the difference compared with the previous value, etc.

[0024] The fastener 501 includes a main body 503 and a movable part 504;

[0025] The inner end of the support arm 50 is fixed to the main body 503;

[0026] One end of the movable part 504 is hinged to one end of the main body part 503;

[0027] The active part 504 and the main body part 503 clamp the screw 20;

[0028] The other end of the movable part 504 and the other end of the main body 503 are equipped with bolts and nuts 505 for locking the movable part 504 and the main body 503.

[0029] In this embodiment, the fasteners can also be the commonly used fasteners on scaffolding, which will not be described in detail here.

[0030] The secondary support plate 80 is provided with a recess 801 for accommodating the measuring sensor 100. By providing the recess, the measuring sensor can be confined, preventing the measuring sensor from shifting or falling off.
