The loading structure comprises a separate loading system and a pressure sensing system. The top plate 1, the loading structure and the loading plate 4 are sequentially arranged from top to bottom above the area to be loaded, and the central axes of the three coincide with each other, so as to facilitate the device fixation and load transmission, and avoid the generation of eccentricity phenomenon caused by unbalanced stress. It should be noted that the up-down arrangement order of the separate loading system and the pressure sensing system can be adjusted according to actual application.

[0026] The number of anchor plate structures 6 is determined according to the loading condition. A plurality of anchor plate structures 6 are fixed on the ground around the top plate 1 in a circumferential angular equidistribution manner, and the distance from the center of the top plate 1 is equal. The anchor plate structure 6 is connected with the top plate 1 through the cable 5.

[0027] The area of the loading plate 4 completely covers the area of the area to be loaded, so as to prevent the area to be loaded from being subjected to inconsistent load in the loading process.

[0028] As shown in the drawings, Figure 4 and Figure 5 The anchor plate structure 6 sequentially comprises an anchor plate bottom plate 602, a steel bonding structure adhesive layer 603 and a bonding medium layer 604 from top to bottom. The anchor plate bottom plate 602 is provided with an anchor plate pull ring 601 integrally formed at the center position. The anchor plate pull ring 601 can facilitate the connection between the anchor plate structure 6 and the top plate 1. The steel bonding structure adhesive layer 603 is used as an intermediate layer, which can greatly improve the bonding strength between the anchor plate bottom plate 602 and the bonding medium layer 604. In a more preferred embodiment, the bonding medium layer 604 uses hot melt adhesive.

[0029] The top plate 1 is provided with a number of holes equal to the number of anchor plate structures 6, so that the cable 5 can pass through the holes and be connected with the corresponding anchor plate pull ring 601. The holes are located on the line connecting the center of the anchor plate structure 6 and the center of the top plate 1, and the distance from all the holes on the top plate 1 to the center of the top plate 1 is equal, so as to ensure the uniformity of the stress of the entire structure.

[0030] The separate loading system comprises a jack 2 and a hydraulic pump connected therewith. The hydraulic pump is used to pressurize the jack to apply load to the top plate 1. The pressure sensing system comprises a pressure sensor 3 and a display instrument connected therewith. The display instrument displays the applied loading pressure.

[0031] The force principle of the counterforce loading device is that the whole anchor plate structure 6 is fixed through the adhesive medium layer 604, and the anchor plate structure 6 is connected with the top plate 1 in the device body through the cable 5, when the jack 2 is loaded, the height of the top plate 1 will be increased with the elongation of the jack main shaft 201, at this time, the cable 5 and the anchor plate structure 6 limit the upward movement of the top plate 1, and generate a counterforce in the opposite direction of the upward movement of the top plate 1, and the data of the loading area in this force condition is measured.

[0032] In order to prevent the anchor plate structure 6 from being suddenly pulled off the adhesive medium layer 604 after reaching the limit load and causing damage to the device or personnel, at least one protection device 7 is arranged outside the single anchor plate structure 6, the protection device 7 is connected with the anchor plate structure 6 through the cable 5, and the protection device 7 is fixed to the ground. The protection device 7 can be fixed to the ground through counterweight.

[0033] The position, number and size of the protection device 7 can be flexibly arranged according to the actual engineering requirements. The friction force of the protection device 7 outside the single anchor plate structure 6 Wherein n is the number of the anchor plate structure 6, and a is the included angle between the cable and the axis of the counterforce loading device (as shown in Figure 1 .

[0034] It should be noted that the shape, size and material of the top plate 1, the loading plate 4 and the anchor plate bottom plate 602 can be adjusted according to the actual engineering, for example, the shape is not limited to the circular shape as shown in the figure, but can also be a square shape. In order to ensure the uniformity of the whole structure, the materials and specifications of all the anchor plate structures 6 in the counterforce loading device are the same.

[0035] Generally, the cable 5 is made of a material that can withstand a large tensile force and is not easy to deform. The tensile force f of a single cable 5 connecting the top plate 1 and the anchor plate structure 6 satisfies the formula Wherein F is the pressure displayed by the pressure sensor 3, n is the number of the anchor plate structure, and a is the included angle between the cable and the axis of the counterforce loading device (as shown in Figure 1 .

[0036] The following briefly describes a setting method of a detachable and portable anchor cable counterforce loading device.

[0037] S1, the position and size of the loading plate 4 are determined according to the loading area, and the area of the loading plate 4 completely covers the area of the loading area.

[0038] S2, the number of the anchor plate structure 6 is selected according to the actual situation of the project, and is fixed to the ground around the top plate 1 in a circumferential direction according to an angle division. In this embodiment, as shown in Figure 2 and Figure 3As shown, three anchor plate structures 6 are needed to be arranged, and the included angle between the center lines of adjacent anchor plate structures 6 is 120°. Therefore, three holes with equal distance from the center of the top plate 1 are provided on the top plate 1 for connecting with the anchor plate structures 6, and each anchor plate pull ring 601 corresponds to a hole on the top plate. In this embodiment, the bonding medium layer 604 adopts hot melt adhesive.

[0039] Before the anchor plate structure 6 is arranged, the lower surface of the anchor plate bottom plate 602 is treated. First, the lower surface of the anchor plate bottom plate 602 is cut to increase the bonding strength of the steel structure adhesive layer 603. After cutting, a layer of steel structure adhesive is covered on the lower surface of the anchor plate bottom plate 602. After the steel structure adhesive solidifies, the steel structure adhesive layer 603 is formed, and the steel structure adhesive layer 603 and the anchor plate bottom plate 602 can be combined into one whole. On this basis, the lower surface of the steel structure adhesive layer 603 is cut and roughened.

[0040] S3, before loading the building structure loading area, remove the loose particles on the surface and use a high-power air blower to blow and wash the surface of the loading area and the surface of the fixed anchor plate structure 6, remove the dust and impurities on the surface and ensure that it is dry.

[0041] S4, after the anchor plate structure 6 is placed, the anchor plate structure 6 is surrounded by solid bricks and other solid surfaces with flat surfaces, the anchor plate structure 6 is removed, and solid hot melt adhesive is placed in the surrounding area for heating and melting. Hot air gun can be used to heat the hot melt adhesive during the melting process. The heating temperature used needs to ensure that the hot melt adhesive has a certain fluidity. While heating and melting the solid hot melt adhesive, it needs to be continuously stirred and spread to ensure that the solid hot melt adhesive is completely melted and has a high degree of engagement with the building surface after melting. After the bonding medium layer 604 is heated and melted, the anchor plate bottom plate 602 and the steel structure adhesive layer 603 that have been combined into one whole are covered on the hot melt adhesive fluid, and sufficient pressure is applied to the anchor plate structure 6 to ensure complete bonding between the interfaces.

[0042] S5, after the bonding medium layer 604 is completely solidified and has a certain strength, the loading plate 4 and the anchor plate 6 are fixed in position, and the pressure sensor 3, the jack 2 and the top plate 1 are arranged in sequence above the loading plate 4. In order to avoid the generation of eccentricity during the loading process, the central axes of the pressure sensor 3, the jack 2 and the top plate 1 are coincided with the central axis of the loading area.

[0043] S6, after the main part of the counter-force device is arranged, the jack 2 and the pressure sensor 3 are connected with the hydraulic pump and the pressure display instrument respectively, and the anchor plate pull ring 601 and the corresponding top plate hole are connected by the cable 5. According to the actual project needs, the protection device 7 is arranged.

[0044] S7, after the whole device has been set up, turn on the power of the pressure display instrument, use the hydraulic pump to pressurize the jack 2, and measure the data of the loading area.

[0045] S8, after the measurement is completed, the counterforce device is removed. First, the cable 5 is removed, and then the top plate 1, the jack 2, the pressure sensor 3 and the loading plate 4 are recovered respectively, the adhesive medium layer 604 is heated until the hot melt adhesive falls off, and the anchor plate 6 and the protection device 7 are recovered respectively.

[0046] The above is only the preferred embodiment of the present application, and is not intended to limit the scope of the present application. It should be noted that for ordinary technicians in the technical field, without departing from the technical principles of the present application, a number of improvements and modifications can be made, which should be covered within the scope of protection of the present application.
