Description

Technical Field

[0001] The utility model relates to the technical field of railing structure testing, in particular to a portable vertical load and horizontal load force application device for a railing. Background Art

[0002] Guardrails play the role of separation and guidance in use. They are important safety facilities on bridges and buildings. Injury accidents caused by insufficient horizontal load resistance of guardrails have occurred frequently. Therefore, all countries have made mandatory regulations on the horizontal load strength of guardrails. In the existing technology, a common solution is to use a large hydraulic jack as a force-applying device to control the size of the load by adjusting the pressure of the hydraulic system. At the same time, the direction of the load can be adjusted by changing the placement direction of the jack. In addition, in order to provide a reaction force, a rigid support is also required. However, there are some problems and disadvantages in the existing technical solutions. First, due to the use of large hydraulic jacks, the weight and volume of the device are large, and it is inconvenient to carry and transport. Secondly, since multiple jacks are required to work at the same time, the number of devices is large, which further increases the weight and volume of the device, and also increases the cost of the device. Thirdly, since the installation position and direction of the jack are not easy to adjust, the installation flexibility and site adaptability of the device are poor. Finally, since each jack needs to be precisely controlled, the measurement work is cumbersome, and the installation stability of the measuring device is also poor.

[0003] Based on this, a portable vertical load and horizontal load force application device for handrails is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content
