Abstract

An automatic grading loading and unloading device in a floor static load test comprises a bearing device made of PVC waterproof cloth; the bearing device is provided with an inlet, an outlet, an inletand outlet valve, a connecting channel and a sensor used for sensing load parameters on the bearing device, wherein the bearing device can be used for bearing a loading material; and the bearing device comprises at least two stages of loading and unloading layers; pressure values sensed by the pressure sensors automatically load and unload the floors at different levels, so a large amount of labor force and time cost are reduced; due to the fact that the sensor is used, loading and unloading load values can be relatively accurate, and good guiding significance is achieved for test results; the device uses fluid as a loading object, and is convenient and simple to use.

Example Embodiment

[0022]The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and the embodiments are intended to be specifically illustrated in the present invention, and the objectives of the present invention should not be considered. Geographical solution and reproduction of the present invention, the scope of the invention should still be based on the scope of the claims.

[0023]The invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024]Such asfigure 1 In a slabable static load test, automatic grading apparatus, including a carrier device made from a PVC waterproof cloth, and an inlet and exit valve, a connection channel, and a sensor for inductive load-load parameters. The carrier device can be used to carry the loading material, the carrier device comprising at least two additional loading layers.

[0025]Further, the carrying device is made of PVC waterproof cloth, and the bag size is customized according to the field floor specification, and the PVC waterproof cloth tensile strength is larger than the bag body in the state of the PVC waterproof cloth based on the verification. Pull stress.

[0026]Further, the carrier device is consistent with the shape of the test floors, the carrier device being a container of the loading material.

[0027]Further, the plus unloading layer is emptied or contracted when there is no load, and is a charged or open state when loading, and the opening state of the waterproof cloth can be apparent that the bearing capacity of the floor can be apparent.

[0028]Further, the load direction of the carrier device is subjected to the lower and the unloading direction is sequentially unloaded from the upper and lower, and the first-level load port is located at the bottom of the carrier device to realize the hierarchical loading effect of the static load test.

[0029]Further, each of the addition of the unloading layer is provided with at least one ante and outlet, an adoption of the loading material, wherein the inlet and export portions corresponding to the first level load port correspond to the position of the other level loading port. Located on different side / ends of the carrier device, there is a force when the fluid enters the first stage load, and the other level of load port is placed on different side / end to ensure the accuracy of the sensor sensing.

[0030]Further, the input and outlet valve is disposed at each of the outlets, and the import and exit portion is a connection passage between the different bags. The valve is inlayed in the channel interface portion. When the water pressure reaches the threshold, the valve is automatically opened, and the upper bag body is passed The channel is connected to the lower bag body.

[0031]Further, the sensor is disposed for each layer of the push-unloading carrier to enter and exit the valve position, fixed to the connection channel, and data is transmitted to the data acquisition system in real time through the wireless data transmission function comes with the sensor.

[0032]Further, the sensor, a pressure sensor, the number of ranges of 0 to 10 MPa, the precision level is 0.1% FS, has a wireless signal transmission function, and transmission of wireless data can be implemented.

[0033]Such asFigure 2-7Take the five-layer addition to the loading layer as an example:

[0034]When the present invention conducts a test, the water pipe is accepted into a first-stage load opening, and the other level of the push-up carrier passes through the valve through the water pressure sensor, when the sensor is induced to the aqueous pressure reaches the preset threshold, the entry and exit valve opening, The first level of loading is performed through the above steps.

[0035]Although the preferred embodiments of the present application have been described, other modifications and modifications can be made to these embodiments once they have known the basic creative concepts. Therefore, the appended claims are intended to be construed as including preferred embodiments and all changes and modifications falling in the scope of this application.
