Description

Technical Field

[0001] The utility model relates to the technical field of keel detection equipment, and particularly relates to a detection device for the load limit of a keel. Background Technique

[0002] The detection device for the load limit of a keel is a special equipment used in the construction industry to evaluate and test the bearing capacity of a keel structure. Keels are the main supporting components in a building structure. They are usually made of wood, steel, concrete or other materials and are used to support roofs, floors, walls, etc. The load limit of a keel refers to the maximum load that a keel can bear without being damaged. In order to ensure the safety and stability of a building, it is necessary to test the load limit of the keel.

[0003] When the existing detection device for the load limit of a keel is in use, it is necessary to clamp the keel. However, the existing clamping device for the keel is not stable. The instability of the clamping device may cause the keel to displace or rotate during the test, thereby affecting the accuracy of the test results. This may lead to an incorrect assessment of the actual bearing capacity of the keel. The instability of the clamping device may cause the keel to suddenly move or fall off during the test, which may cause harm to the operator and increase the safety risk.
