Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in FIGS. 1 to 6, the ground anchor device for the reaction wall of the present embodiment includes: anchor slab 1, backing plate 3, protective sleeve 4, counter-force biography power component 5 and at least one screw rod 2, on anchor slab 1 was connected to the one end of screw rod 2, backing plate 3 was connected to the other end, and protective sleeve 4 is located backing plate 3 and deviates from anchor slab 1 one side, and forms the accommodation space who is used for holding counter-force biography power component 5 with backing plate 3, and counter-force biography power component 5 detachably installs in accommodation space.
Anchor plate 1 is pre-buried before concrete placement, and anchor plate 1 is connected to screw rod 2, and after concrete placement sclerosis, anchor plate 1 and screw rod 2 provide the main anchoring power of whole device. The lower end of the screw rod 2 is connected with the anchor plate 1, the upper end of the screw rod 2 is connected with the extending backing plate 3, the height of the extending backing plate is slightly lower than the ground, the number and the arrangement positions of the screw rods 2 are only indicated in the figure, the number and the arrangement positions of the screw rods 2 can be adjusted according to the size and the direction of the required counter force, and if the counter force is oblique counter force, the screw rods 2 can be obliquely arranged along the direction of the. When concrete placement, because be equipped with protective sleeve 4 on the backing plate 3, can avoid the concrete to invade accommodation space when concreting, pollute screw rod 2 and backing plate 3, also can protect screw rod 2 and backing plate 3 in the later stage use, backing plate 3 can reduce stress concentration, avoids the concrete to be crushed. The backing plate 3 and the protective sleeve 4 may be made of steel materials in accordance with the requirements. The reaction force transmission member 5 is customized according to the form of the rod or other connection part to which it is connected, e.g. the top of the reaction force transmission member 5 may be made as a threaded socket connection screw, as shown in fig. 4, or as a hinged connection to accommodate forces in different directions, as shown in fig. 5.
In the ground anchor device for the reaction wall of the embodiment, the reaction force transmission member 5 is detachably installed in the accommodating space instead of being fixedly embedded, so that on the premise of meeting the design load strength, different reaction force transmission members 5 are replaced to connect rod pieces or other connecting parts with different sections, different types, different sizes and different directions, and the application range of the whole reaction wall is expanded. In addition, the ground anchor device for the counterforce wall has the advantages of convenience in installation, accuracy in positioning, high safety storage, reasonable structure (clear stress), economy, cheapness and the like.
In this embodiment, the backing plate 3 is provided with a first through hole 31, the reaction force transmission member 5 is provided with a second through hole 51, and the screw rod 2 passes through the first through hole 31 and the second through hole 51 and is screwed on the screw rod 2 through the first nut 8, so as to mount the reaction force transmission member 5 on the backing plate 3. The through hole of the counter force transmission component 5 is directly sleeved on the screw rod 2 penetrating through the backing plate 3 and is detachably arranged on the backing plate 3 through the first nut 8.
Usually, a screw hole is arranged in the anchor plate 1, and during installation, after the screw 2 penetrates through the anchor plate, the screw 2 is fixedly connected with the anchor plate 1 by a second nut 7. For convenient processing and location, anchor slab 1 and screw rod 2 integrated into one piece do not need when the installation counterpoint and installation, improve the installation effectiveness.
