Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a supporting anchor cable reaction device. Background Art

[0002] At present, a large number of high-rise buildings are under construction, resulting in a large number of deep foundation pit projects, and deep foundation pit support problems have also arisen. As a deep foundation pit support method, the anchor cable has its free end connected to the waist beam, and the anchor end is inserted into the stable stratum, transferring the soil pressure outside the sliding surface to the stable stratum through the anchor section. In order to determine whether the anchor cable has achieved the ideal effect, the pull-out bearing capacity of the anchor cable must be tested. The pull-out bearing capacity test of the anchor cable requires the jack to be fixed. However, the traditional method of fixing with iron plates has serious deformation when it exceeds 50 tons, the soil is loose, and landslides occur. Utility Model Content

[0037] Reference below Figure 1-Figure 3 A support anchor cable reaction device is described in detail with a specific embodiment. It is worth noting that the following description is only an exemplary description and not a specific limitation of the utility model.

[0038] like Figure 1-Figure 3 As shown, a support anchor cable reaction device includes a base and a reaction platform.

[0039] The base includes a bottom plate 100 and two piers 110 respectively fixed on the bottom plate 100; the reaction platform includes two steel beams 120 connecting the two piers 110 and a mounting plate 130 fixed on the two steel beams 120. A clamping groove 140 is provided between the two steel beams 120. The mounting plate 130 is provided with a mounting opening 150 corresponding to the clamping groove 140. The clamping groove 140 and the mounting opening 150 are used to fix and install the jack. By setting the bottom plate 100, the base greatly increases the contact area with the ground and reduces the bearing capacity required by the soil. The two piers 110 are respectively fixed on the bottom plate 100 and provide pressure to the bottom plate 100, so that the bottom plate 100 is evenly stressed. The reaction platform is formed by welding two steel beams 120 on the pier 110, with a clamping groove 140 between the two steel beams 120, and a mounting plate 130 welded on the two steel beams 120, with a mounting opening 150 corresponding to the clamping groove 140 on the mounting plate 130, and the mounting opening 150 and the clamping groove 140 are used to fix the jack, and the mounting opening 150 and the limiting groove can effectively solve the problem of fixing the jack. Therefore, the pull-out test of the support anchor cable with a bearing capacity of 200 tons can be achieved, and the modified device has lower requirements on the bearing capacity of the foundation and less site limitations.

[0040] Specifically, Figure 1 and Figure 2As shown, there are two bottom plates 100, and two piers 110 are fixed on the two bottom plates 100 respectively. The two piers 110 are fixed on the two bottom plates 100 respectively, and the two piers 110 provide pressure to the two bottom plates 100 respectively, so that the two bottom plates 100 are evenly stressed. Moreover, the shape of the bottom plate 100 is square. The bottom plate 100 is square for easy processing and installation. Moreover, the bottom plate 100 is a steel plate with a length of 3m, a width of 2m, and a thickness of 2cm. This device uses two large steel plates that can be 3 meters long, 2 meters wide, and 2cm thick, with a contact area of ​​12 square meters with the ground, which greatly increases the contact area with the ground and reduces the bearing capacity required for the soil. Furthermore, a lifting ring 160 is provided on the bottom plate 100. This facilitates the lifting and handling of the entire test device and greatly improves the transportation efficiency.

[0041] It should be noted that if Figure 2 and Figure 3 As shown, the steel beam 120 is an I-beam. The use of an I-beam is conducive to installation, while ensuring the contact area with the mounting plate 130 and improving the support. In addition, the two steel beams 120 are arranged in parallel. The steel beams 120 are arranged in this way to ensure that the width of the positioning grooves 140 is consistent, which can reduce the difficulty of installing the mounting plate 130 and facilitate the installation and fixation of the jack.

[0042] It is worth mentioning that Figure 2 As shown, the shape of the mounting plate 130 is square. The square shape of the mounting plate 130 is convenient for processing and installation. Accordingly, the shape of the mounting opening 150 is circular. The mounting opening 150 is set to be circular to facilitate installation with the jack. In addition, the mounting plate 130 is provided with a limit rod 170 for limiting the jack on the outer side of the mounting opening 150. The setting of the limit rod 170 can limit the outer side of the jack, further improving the stability of the jack installation.

[0043] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
