Technical Field

[0001] The utility model relates to the technical field of concrete stiffeners, in particular to a concrete stiffener for composite foundation treatment. Background Art

[0002] Composite foundation refers to an engineering method that uses different types of materials and technologies to improve the foundation soil. In civil engineering, composite foundation is often used to strengthen weak foundations or improve the bearing capacity of foundation soil to support the construction of buildings or other structures.

[0003] In order to strengthen and improve the foundation soil and increase the bearing capacity and stability of the soil, a special type of geotechnical material, namely concrete stiffener, also known as stiff concrete, is often used to improve the strength and rigidity of the composite foundation.

[0004] At present, in the application process of concrete rigid bodies, steel sections are often used, and steel bars are sleeved and welded on the outside of the steel sections, thereby achieving the practical effect of saving concrete and increasing the use space.

[0005] However, currently, steel bars are often directly connected to steel sections by welding. Because steel sections are usually high and long, directly welding steel bars on the outside requires workers to frequently climb up and down to get the steel bars, which not only consumes workers' physical strength but also reduces construction efficiency. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a concrete rigid body for composite foundation treatment. When users assemble steel bars and steel sections, workers do not need to climb up and down to get the steel bars. They only need to stand on the ground and connect several vertical steel bars and transverse steel bars at the same height to the fastening components and connecting components on the movable plate respectively, and then move them to the corresponding positions and weld them uniformly, which is convenient and quick.

[0007] The utility model provides the following technical solution: a concrete rigid body for composite foundation treatment, comprising a cross-shaped steel and four side plates installed at the four ends of the cross-shaped steel, wherein the surfaces of the four side plates are penetrated with sliding grooves, the inner walls of the sliding grooves are slidably connected with locking components, the end of the locking component away from the cross-shaped steel is connected to a movable plate, the side of the movable plate away from the cross-shaped steel is fixedly connected to two support plates and a plurality of fastening components, the sides of the two support plates away from each other are connected to connection components, and the plurality of fastening components are located between the two support plates.

[0008] Furthermore, the locking assembly includes a sliding rod and a nut, one end of the sliding rod passes through the sliding groove, the movable plate and the nut, and is threadedly connected to the inner wall of the nut, the outer wall of the sliding rod is slidingly connected to the penetration point of the sliding groove and the movable plate, and the side of the nut close to the cross-shaped steel is abutted against the side of the movable plate away from the cross-shaped steel.

[0009] Furthermore, the number of the sliding grooves and the locking components is no less than two groups, and they are evenly distributed from the center of the movable plate to both ends.

[0010] Furthermore, the connection assembly includes a plurality of internally threaded rods, and the same end of the plurality of internally threaded rods is fixedly connected to the surface of the support plate.

[0011] Furthermore, the connecting assembly includes a sleeve rod, a threaded ring and several sector blocks, one end of the sleeve rod is fixedly connected to the side of the movable plate away from the cross steel, the other end of the sleeve rod is fixedly connected to one side of the several sector blocks, and the threaded ring is sleeved and threadedly connected to the outer walls of the several sector blocks.

[0012] Furthermore, an abutment plate is fixedly connected to the outer wall of the sleeve rod, and a side of the abutment plate away from the cross-shaped steel abuts against a side of the threaded ring close to the cross-shaped steel.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] This kind of concrete rigid body for composite foundation treatment is achieved by arranging movable plates on the four side plates of the cross-shaped steel, connecting the fastening components and the two supporting plates through the movable plates, and arranging the connecting components on the side where the two supporting plates are away from each other.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1-Figure 4 A concrete rigid body for composite foundation treatment includes a cross steel 1 and four side plates 2 installed at the four ends of the cross steel 1. The surfaces of the four side plates 2 are all penetrated by a slide groove 201. The inner wall of the slide groove 201 is slidably connected with a locking component. The end of the locking component away from the cross steel 1 is connected to a moving plate 3. The side of the moving plate 3 away from the cross steel 1 is fixedly connected to two support plates 4 and a plurality of fastening components. The sides of the two support plates 4 away from each other are both connected with a connecting component, and the plurality of fastening components are located between the two support plates 4.

[0022] like Figures 1 to 4 As shown, when assembling the concrete rigid body for composite foundation treatment in the utility model, the steel section is first fixed to the foundation base surface, and then the workers start to assemble the steel bars from the bottom of the steel section. First, one end of several transverse steel bars is inserted into the fastening assembly, and they are uniformly fixed and clamped by the fastening assembly. Then, the other end of these transverse steel bars is fixed to several fastening assemblies of another steel section to complete the fixation of the other end. Then, the movable plate 3 is slid upward along the slide groove 201 through the locking assembly. When it slides to the specified position, it is locked and limited again by the locking assembly, and then the installation of the transverse steel bars is completed at this time. , and then insert the upper end of the vertical steel bar into the connecting assembly of the lower support plate 4 to fix the upper end of the vertical steel bar, and then connect the lower end of these vertical steel bars to the connecting assembly of a support plate 4 above another movable plate 3, so as to complete the fixation of the two ends of the vertical steel bar, and then assemble the transverse steel bars and vertical steel bars on the other sides in the same way, and after all are installed, they can be welded uniformly by a welding machine, which is convenient and fast. Finally, after all welding is completed, the frame can be filled with concrete according to the normal construction procedure, thereby improving the overall strength and rigidity of the composite foundation.

[0023] Please refer to Figure 2 and Figure 3 The locking assembly includes a slide bar 6 and a nut 7. One end of the slide bar 6 passes through the slide slot 201, the moving plate 3 and the nut 7, and is threadedly connected to the inner wall of the nut 7. The outer wall of the slide bar 6 is slidably connected to the slide slot 201 and the moving plate 3 at the penetration point. The side of the nut 7 close to the cross-shaped steel 1 is against the side of the moving plate 3 away from the cross-shaped steel 1. The number of the slide slot 201 and the locking assembly is not less than two groups, and they are equidistantly distributed from the center of the moving plate 3 to both ends.

[0024] More specifically, when the height of the movable plate 3 needs to be changed, it is only necessary to rotate the nut 7. After the nut 7 is rotated, it moves on the surface of the slide rod 6, thereby creating a gap between the movable plate 3 and the side plate 2. Then, according to construction requirements, the movable plate 3 can be slid up or down along the slide groove 201 to change the height of the two support plates 4 and several fastening components. After the height is adjusted, the nut 7 is rotated again to squeeze the movable plate 3 and the side plate 2 again to prevent the movable plate 3 from sliding down. Setting the number of slide grooves 201 and locking components to more than two groups can make the force more uniform and prevent idling.

[0025] Please refer to Figure 1-Figure 3 The connecting assembly includes a plurality of internally threaded rods 5 , and the same end of the plurality of internally threaded rods 5 is fixedly connected to the surface of the supporting plate 4 .

[0026] More specifically, a plurality of internal threaded rods 5 are provided, and the vertical reinforcement can be fixed by simply screwing one end of the vertical reinforcement into the internal threaded rod 5 through a threaded manner, and the operation is convenient and easy.

[0027] Please refer to Figure 2-Figure 4 The fastening assembly includes a sleeve rod 8, a threaded ring 9 and a plurality of sector blocks 10. One end of the sleeve rod 8 is fixedly connected to the side of the moving plate 3 away from the cross-shaped steel 1, and the other end of the sleeve rod 8 is fixedly connected to one side of the plurality of sector blocks 10. The threaded ring 9 is sleeved and threadedly connected to the outer wall of the plurality of sector blocks 10. The outer wall of the sleeve rod 8 is fixedly connected with a butt plate 11, and the side of the butt plate 11 away from the cross-shaped steel 1 butts against the side of the threaded ring 9 close to the cross-shaped steel 1.

[0028] More specifically, when it is necessary to connect transverse steel bars, one end of the transverse steel bars only needs to be inserted into a number of sector blocks 10, threaded rings 9 and sleeve rods 8, and then the threaded rings 9 are rotated. As the threaded rings 9 rotate, they can move on the surfaces of the sector blocks 10, and in the process of movement, the sector blocks 10 can be squeezed toward the middle through their own slopes and the raised parts of the sector blocks 10, thereby fixing the middle steel bars. This is simple and easy to operate.

[0029] The last point that needs to be emphasized is that after fixing the steel bars through the locking components, connecting components and fastening components, the tightening effect can also be achieved. If it feels unstable, you can weld them together after all the steel sections and steel bars are assembled. Compared with welding one steel bar at a time, welding them together is also more convenient and quicker.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
