[0032] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the following will further describe the present application. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in other ways different from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present application, not all the embodiments.

[0034] The bag type prestressed anti-floating anchor rod needs to be tensioned and locked before the construction of the cushion layer after the pile forming.

[0035] The site is generally in the construction stage of simultaneous earth excavation and anchor rod construction. In the process of tensioning the anchor rod by the through hydraulic device (through jack), the through hydraulic device directly contacts the soil surface. In the process of the through hydraulic device applying tension to the anchor rod, the device will extrude the soil around the device, which is easy to cause uneven subsidence of the soil and affect the flatness of the construction site.

[0036] To solve the above technical problems, referring to Figure 1 and Figure 2 The present application provides a tensioning pedestal 100, which can include a bottom plate 110, a first support plate 121, a second support plate 131, a cushion plate 140 and a positioning rod 150.

[0037] The bottom plate 110 can be formed into a rectangular plate, a circular plate, a triangular plate, a trapezoidal plate, etc. In the specific implementation process, the bottom plate 110 is formed into a rectangular plate. The first functional hole 111 is provided on the bottom plate 110. The first functional hole 111 is located at the center position of the rectangular bottom plate 110. The first functional hole 111 penetrates the bottom plate 110. The construction hole is located in the orthographic projection of the first functional hole 111 on the ground. That is, the upper side of the first functional hole 111 is directed towards the ground, and the construction hole can be observed.

[0038] The first support plate 121 and the second support plate 131 are arranged on the side of the bottom plate 110 away from the ground, that is, the first support plate 121 and the second support plate 131 are arranged on the upper surface of the bottom plate 110. The plane on which the first support plate 121 is located (for example, the plane defined by the upper and lower front and rear shown in Figure 1 The plane on which the second support plate 131 is located (for example, the horizontal plane defined by the front and rear and left and right shown in Figure 1 The plane on which the second support plate 131 is located (for example, the horizontal plane defined by the front and rear and left and right shown in Figure 1 The first support plate 121 and the second support plate 131 are arranged in a spaced manner.

[0039] Wherein, the "vertical" refers to substantially vertical, that is, the included angle between the first support plate 121 and the bottom plate 110 can be 80° to 90°, and the included angle between the second support plate 131 and the bottom plate 110 can be 80° to 90°.

[0040] Specifically, the first support plate 121 and the second support plate 131 can be fixed on the bottom plate 110 in the form of welding.

[0041] The backing plate 140 is erected on the first support plate 121 and the second support plate 131, and the bottom plate 110 is provided with a second functional hole 141, which is arranged opposite to the first functional hole 111. The hydraulic device 200 abuts against one side of the backing plate 140 away from the bottom plate 110, and the anchor rod can pass through the second functional hole 141 and the hydraulic device 200.

[0042] Specifically, the second functional hole 141 can be coaxially arranged with the first functional hole 111, and the hole diameter of the second functional hole 141 is smaller than the outer diameter of the hydraulic device 200.

[0043] It should be understood that after the construction hole is grouted and formed, the formed structure may protrude above the ground. By arranging the first support plate 121 and the second support plate 131 to space the backing plate 140 from the bottom plate 110, normal construction can be ensured.

[0044] In this way, in the process of tensioning the anchor rod by the hydraulic device 200, the hydraulic device 200 exerts a pressure on the backing plate 140 towards the ground. The pressure is transmitted to the first support plate 121 and the second support plate 131 through the backing plate 140, and is transmitted to the bottom plate 110 through the first support plate 121 and the second support plate 131. The pressure is transmitted to the ground through the bottom plate 110. Compared with the direct contact between the hydraulic device 200 and the ground, the contact area between the bottom plate 110 and the ground is larger, the pressure per unit area is reduced, and the uneven subsidence of the soil after the operation is reduced, thereby maintaining the flatness of the construction site.

[0045] One end of the positioning rod 150 is connected to the bottom plate 110, and the other end extends towards the underground. In the process of operation, the positioning rod 150 is inserted into the underground to avoid the shaking of the tensioning pedestal 100 during construction, thereby ensuring the stability of the hydraulic device 200 during construction.

[0046] In the specific implementation process, the number of positioning rods 150 can be multiple, and the multiple positioning rods 150 are arranged at intervals to further avoid the shaking of the tensioning pedestal 100 during construction.

[0047] Taking the bottom plate 110 as a rectangular plate for example, the number of positioning rods 150 can be four, which are respectively located at the four diagonal positions of the bottom plate 110.

[0048] The positioning rod 150 can be formed as a conical rod with an arrow pointing downward.

[0049] In some embodiments of the present application, please refer to Figure 1 and Figure 2 The tensioning pedestal 100 can further include a third support plate 161 and a fourth support plate 171. The third support plate 161 is perpendicular to the plane of the bottom plate 110 and is arranged on the first support plate 121 and the second support plate 131. The fourth support plate 171 is also perpendicular to the plane of the bottom plate 110 and is arranged on the first support plate 121 and the second support plate 131. The fourth support plate 171 is spaced apart from the third support plate 161, and the cushion plate 140 is arranged on the third support plate 161 and the fourth support plate 171.

[0050] Thus, by arranging the third support plate 161 and the fourth support plate 171, the cushion plate 140 can be further spaced apart from the bottom plate 110, and the cushion plate 140 can be provided with a mounting position.

[0051] In a specific implementation process, the first support plate 121 and the second support plate 131 are arranged in the left-right direction, the third support plate 161 and the fourth support plate 171 are arranged in the front-rear direction, and the cushion plate 140 is arranged at a middle position in the extension direction of the third support plate 161 and the fourth support plate 171. When the force is transmitted from the cushion plate 140 to the third support plate 161 and the fourth support plate 171, the force is further transmitted from the third support plate 161 and the fourth support plate 171 to the first support plate 121 and the second support plate 131, and then transmitted from the first support plate 121 and the second support plate 131 to the bottom plate 110, and finally transmitted from the bottom plate 110 to the ground.

[0052] Further, the third support plate 161 includes a first end portion 1611 and a second end portion 1612. The first end portion 1611 is located outside the bottom plate 110 in the orthographic projection of the plane of the bottom plate 110, that is, the first end portion 1611 extends out of the bottom plate 110. The tensioning pedestal 100 can further include a first tension rod 162. One end of the first tension rod 162 is connected to the first end portion 1611, and the other end is connected to the bottom plate 110.

[0053] It should be noted that when the force is transmitted from the cushion plate 140 to the third support plate 161 and the fourth support plate 171, the force extends along the direction of the third support plate 161 (for example Figure 1The deformation of the first end portion 1611 and the second end portion 1612 can be improved by setting the first tension rod 162 to exert a downward tension on the first end portion 1611 through the bottom plate 110, thereby improving the stability of the whole tension seat 100 during the operation process.

[0054] Further, the second end portion 1612 is located outside the bottom plate 110 in the orthographic projection on the plane of the bottom plate 110; the tension seat 100 can further include a second tension rod 163, one end of the second tension rod 163 being connected with the second end portion 1612, and the other end being connected with the bottom plate 110.

[0055] Thus, the deformation of the second end portion 1612 can be improved by setting the second tension rod 163 to exert a downward tension on the second end portion 1612 through the bottom plate 110, thereby improving the stability of the whole tension seat 100 during the operation process.

[0056] Still further, the fourth support plate 171 can include opposite third and fourth end portions, and the tension seat 100 further includes a third tension rod 172 and a fourth tension rod, one end of the third tension rod 172 being connected with the third end portion, and the other end being connected with the bottom plate 110, one end of the fourth tension rod being connected with the fourth end portion, and the other end being connected with the bottom plate 110.

[0057] In this way, the deformation of the fourth support plate 171 can be improved by setting the third and fourth tension rods 172 and 163 to exert a downward tension on the third and fourth end portions through the bottom plate 110, thereby further improving the stability of the tension seat 100 during the operation process.

[0058] In some embodiments of the present application, the tension seat 100 can further include a first contact plate 122 and a second contact plate 132, the plane of the first contact plate 122 being parallel to the plane of the bottom plate 110, and the first contact plate 122 being connected with one end of the first support plate 121 away from the bottom plate 110; the plane of the second contact plate 132 being parallel to the plane of the bottom plate 110, and the second contact plate 132 being connected with one end of the second support plate 131 away from the bottom plate 110; and the three support plates and the fourth support plate 171 being erected on the first and second contact plates 122 and 132.

[0059] Thus, by arranging the first contact plate 122 and the second contact plate 132, the connection of the first support plate 121, the second support plate 131, the third support plate 161 and the fourth support plate 171 is realized, for example, the first support plate 121 and the third support plate 161 are connected by the first contact plate 122, by arranging the first contact plate 122, the welding area can be increased, and the stability of the connection between the first support plate 121 and the third support plate 161 is ensured.

[0060] In some embodiments of the present application, the tensioning pedestal 100 can further include a third contact plate 164, the plane in which the third contact plate 164 is parallel to the plane in which the bottom plate 110 is located, the third contact plate 164 is connected to one end of the third support plate 161 facing the bottom plate 110, and is connected to the first contact plate 122 and the second contact plate 132. Thus, by arranging the third contact plate 164, the first contact plate 122 and the second contact plate 132, the stress area between the third support plate 161 and the first support plate 121 and the second support plate 131 can be increased, and stress concentration can be reduced.

[0061] Further, the tensioning pedestal 100 can further include a fourth contact plate 165, the plane in which the fourth contact plate 165 is parallel to the plane in which the bottom plate 110 is located, the fourth contact plate 165 is connected to one end of the third support plate 161 away from the bottom plate 110, and the gusset plate 140 is connected to the fourth contact plate 165.

[0062] In this way, by arranging the fourth contact plate 165, the stress area between the gusset plate 140 and the third support plate 161 can be increased, and stress concentration can be reduced, and the stability of the tensioning pedestal 100 during operation can be improved.

[0063] At the same time, the gusset plate 140 can be connected to the fourth contact plate 165 by welding.

[0064] Among them, the third support plate 161, the third contact plate 164 and the fourth contact plate 165 can be collectively formed into an I-shaped steel structure.

[0065] Further, the tensioning pedestal 100 can further include a fifth contact plate 173, the fifth contact plate 173 is connected to one end of the fourth support plate 171 facing the bottom plate 110, and is connected to the first contact plate 122 and the second contact plate 132. Thus, by arranging the fifth contact plate 173, the first contact plate 122 and the second contact plate 132, the stress area between the fourth support plate 171 and the first support plate and the second support plate 131 can be increased, and stress concentration can be reduced.

[0066] The tensioning pedestal 100 can further include a sixth contact plate 174, the sixth contact plate 174 is connected to one end of the fourth support plate 171 away from the bottom plate 110, and the gusset plate 140 is connected to the sixth contact plate 174.

[0067] In this way, by arranging the sixth contact plate 174, the force receiving area between the cushion plate 140 and the fourth support plate 171 can be increased, stress concentration can be reduced, and the stability of the tensioning pedestal 100 during operation can be improved.

[0068] Meanwhile, the cushion plate 140 can be connected with the sixth contact plate 174 by welding.

[0069] Among them, the fourth support plate 171, the fifth contact plate 173 and the sixth contact plate 174 can be collectively formed in an I-shaped steel structure.

[0071] Therefore, the integrity of the third support plate 161 and the fourth support plate 171 is improved, and the separation of the third support plate 161 and the fourth support plate 171 during operation is reduced.

[0072] In the specific implementation process, the number of auxiliary connecting plates 180 can be multiple, and the multiple auxiliary connecting plates 180 are arranged at intervals in the extension direction of the third support plate 161, further improving the integrity between the third support plate 161 and the fourth support plate 171.
