Description

Technical Field

[0001] This application relates to the field of building pile foundation quality testing technology, and in particular to a static load testing device for building pile foundations. Background Technology

[0002] To ensure the quality of construction projects, it is essential to test the bearing capacity of the foundation and pile foundation during the construction process. Currently, static load testing is a recognized method for testing the vertical bearing capacity of pile foundations, as it is the most intuitive and reliable method.

[0003] During static load testing of pile foundations, counterweights need to be hoisted onto the load-bearing frame one by one using a crane. After the test is completed, the counterweights need to be unloaded one by one using a crane. However, during the stacking and dismantling process, counterweights at the edges are prone to instability due to improper operation by hoisting personnel, uneven placement of counterweights, or being squeezed by other counterweights. This can lead to slippage and cause the counterweights to fall off the load-bearing frame, resulting in damage to the counterweights and threatening the safety of personnel and equipment on the ground. Summary of the Invention

[0004] This application aims to at least partially solve one of the aforementioned technical problems in the prior art. To this end, embodiments of this application provide a static load testing device for building pile foundations to prevent the counterweight from slipping off the testing device during loading and unloading, thus preventing damage to the counterweight and injury to ground equipment and personnel.

[0005] A static load testing device for building pile foundations includes a building pile foundation, a lifting jacking device, and an auxiliary support. The lifting jacking device is installed above the building pile foundation, and the auxiliary support is installed on both sides of the building pile foundation. A first longitudinal H-beam is installed above the lifting jacking device. Multiple transverse H-beams are longitudinally spaced above the first longitudinal H-beam. The two ends of the transverse H-beams overlap the auxiliary support located on both sides of the building pile foundation. Several static load test standard counterweights are stacked on top of the transverse H-beams. Multiple second longitudinal H-beams are fixed at intervals on the two transverse H-beams at both ends of the first longitudinal H-beam. Vertical rod fixing seats are installed at both ends of the transverse H-beams and the ends of the second longitudinal H-beams. Vertical rods are installed on the vertical rod fixing seats, and connectors are installed at the top of the vertical rods. The connectors in the same row are connected by crossbars.

[0006] In an optional or preferred embodiment, the vertical rod fixing seat includes a fixing member that is inserted into the end of the transverse I-beam and the end of the second longitudinal I-beam and fixed by threaded fasteners.

[0007] In an optional or preferred embodiment, the vertical rod is detachably connected to the fixing member.

[0008] In an optional or preferred embodiment, the fixing member is provided with a threaded groove, and the bottom end of the vertical rod is threadedly connected to the threaded groove.

[0009] In an optional or preferred embodiment, the connector includes a horizontal connecting pipe and a vertical connecting pipe, wherein the horizontal connecting pipe and the vertical connecting pipe are connected in a "T" shape and are internally connected.

[0010] In an optional or preferred embodiment, limit devices are installed at both ends of the crossbar.

[0011] In an optional or preferred embodiment, the limiting device is a nut.

[0012] Based on the above technical solution, the embodiments of this application have at least the following beneficial effects: by installing vertical rod fixing seats at the ends of the transverse H-beam and the second longitudinal H-beam, and installing vertical rods on the vertical rod fixing seats, the vertical rod device forms a circle, which can block the counterweight block at the edge position, preventing the counterweight block from slipping off the detection device during loading and unloading, causing damage to the counterweight block and injury to ground equipment and personnel.
