Description

Technical Field

[0001] This application relates to the technical field of high slope treatment in water conservancy projects, and particularly relates to a steel bar cage retaining wall structure. Background Art

[0002] During the construction of the dam of a mountain hydropower station, a temporary and simple road will be built first by an excavator or a bulldozer for vehicles to drive and transport engineering materials. However, part of the road is located on the side downstream of the toe slab on the left bank of the dam, and this position belongs to a high filling area. If it is filled according to the natural slope, it will occupy the building line of the main structure of the dam. Therefore, in order not to affect the construction of the main structure of the dam, steel bar cages will be installed at this position and stones will be placed into the steel bar cages to form reinforced stone cages. After that, the reinforced stone cages will be stacked in multiple layers and used as retaining walls to support the road slope.

[0003] During the production process of the steel bar cage, workers need to first cut the steel bars into the required lengths, and then splice and weld multiple steel bars together to form a steel bar cage with a size of 2m * 1m * 1m (length * width * height). In the related art, in order to ensure that the mesh sizes formed by the steel bar cages are relatively uniform, before welding each steel bar cage, workers need to first measure the corresponding lengths with a ruler, then use a marker pen to make marks at the corresponding positions, and then place the corresponding steel bars at the marked positions. At the same time, one hand needs to fix the steel bars to prevent them from shaking, and then weld them. As a result, the welding process of the steel bar cage is relatively cumbersome and not convenient enough. Utility Model Content

[0004] In order to improve the convenience during the welding process of the steel bar cage, this application provides a steel bar cage retaining wall structure.

[0005] A steel bar cage retaining wall structure provided by this application adopts the following technical solutions:

[0006] A steel bar cage retaining wall structure includes steel bar frames and steel bar meshes. A plurality of the steel bar frames and a plurality of the steel bar meshes are spliced with each other to form a cuboid steel bar frame capable of accommodating stones;

[0007] The steel bar frame includes horizontal main steel bars and vertical main steel bars. Positioning welding holes for inserting the ends of the vertical main steel bars are formed on the horizontal main steel bars. Part of the steel bar meshes are welded to the horizontal main steel bars, and part are welded to the vertical main steel bars. First positioning slots for inserting the steel bar meshes are formed on the horizontal main steel bars, and second positioning slots for inserting the steel bar meshes are formed on the vertical main steel bars.

[0008] In order to increase the contact area between the horizontal main reinforcement bars and the vertical main reinforcement bars and improve the stability after welding, a contact plane that fits the end of the vertical main reinforcement bar is provided on the outer wall of the horizontal main reinforcement bar close to the vertical main reinforcement bar.

[0009] In order to make the diameter of the vertical main reinforcement bar not affected by the aperture size of the positioning welding hole, the positioning welding hole is located within the contact plane, and a positioning column inserted into the positioning welding hole is welded to the end of the vertical main reinforcement bar.

[0010] In order to enable the stacking of the cuboid steel bar frames so that the positioning columns on one of the adjacent two cuboid steel bar frames can be inserted into the positioning welding holes in the other cuboid steel bar frame to make the stacking neater, two horizontal main reinforcement bars are provided, and the two horizontal main reinforcement bars are respectively located at both ends of the vertical main reinforcement bar, and the two horizontal main reinforcement bars are symmetrically arranged;

[0011] Positioning columns are provided at both ends of the vertical main reinforcement bar. The positioning column at one end of the vertical main reinforcement bar protrudes from the corresponding positioning welding hole, and there is a clearance between the positioning column at the other end and the orifice on the other side of the positioning welding hole.

[0012] In order to enable the steel bar mesh to be positioned and docked with the first positioning groove and the second positioning groove, a plurality of connecting steel bars protrude from the periphery of the steel bar mesh, and the plurality of connecting steel bars are respectively inserted into the corresponding first positioning slots and the second positioning slots.

[0013] In order to prevent the steel bar mesh from being disconnected from the steel bar frame easily after being squeezed by the stones inside the cuboid steel bar frame, the second positioning slot is opened on the inner wall of the vertical main reinforcement bar.

[0014] In order to prevent the multi-layer cuboid steel bar frames from being misaligned when they are filled with stones and stacked together, angle irons that can position and stack the multi-layer cuboid steel bar frames together are welded at the four right angles at the top of the cuboid steel bar frame.

[0015] In order to improve the overall strength of the steel cage, the horizontal main reinforcement bars and the vertical main reinforcement bars are both grade-3 steel bars with a diameter of 20 mm, and the steel bar mesh is grade-1 steel bars with a diameter of 6.5 mm.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1. Since the positioning welding holes, the first positioning slots, and the second positioning slots are all processed and formed during the cutting of the reinforcing bars, when welding the reinforcing bar frame, the vertical main reinforcing bars can be directly inserted into the positioning welding holes of the horizontal main reinforcing bars through the positioning columns, and then the circumferential sides of the vertical main reinforcing bars and the horizontal main reinforcing bars in contact are welded. This process no longer requires welders to measure the positions and hold the reinforcing bars with one hand during welding, thus making the process of welding the reinforcing cage more convenient;

[0018] 2. The reinforcing bar mesh is a pre-processed or purchased finished product. Therefore, when welding the reinforcing cage, it only needs to weld the reinforcing bar mesh between two adjacent vertical main reinforcing bars. And when welding the reinforcing bar mesh, the reinforcing bar mesh will also be positioned and installed in the first positioning slot and the second positioning slot, thus making it more convenient to weld the reinforcing bar mesh;

[0019] 3. After multiple reinforcing cages are stacked together, the positioning columns on one side between two adjacent reinforcing cages will be inserted into the positioning welding holes of the other reinforcing cage. At the same time, under the action of the angle irons, two adjacent reinforcing cages will be more neatly arranged and not prone to deviation and dislocation. Description of the Drawings

Detailed Embodiment

[0024] The following will further elaborate on the present application Figures 1-3 with reference to the attached drawings.

[0025] The embodiment of the present application discloses a reinforcing cage retaining wall structure. Refer to Figure 1, The steel cage retaining wall structure includes steel bar frames 1 and steel bar meshes 2. There are multiple steel bar frames 1 and multiple steel bar meshes 2. After the multiple steel bar frames 1 and multiple steel bar meshes 2 are spliced with each other, they are welded to form a rectangular steel frame 3 with an open top, and then stones can be put into the rectangular steel frame 3 through the opening. The steel bar meshes 2 are positioned on the steel bar frames 1 and then the steel bar meshes 2 will be welded to the steel bar frames 1. The steel bar meshes 2 are prefabricated parts or purchased parts. Compared with welding a steel bar mesh 2 on the steel frame, directly using the finished steel bar meshes 2 improves the convenience during welding.

[0026] To improve the overall strength of the steel cage, in this embodiment, it is preferred that the steel bars in the steel bar frames 1 are grade III steel bars with a diameter of 20 mm; the steel bars in the steel bar meshes 2 are grade I steel bars with a diameter of 6.5 mm.

[0027] Refer to Figure 1 And Figure 2 , Since the top of the rectangular steel frame 3 is open and formed by splicing and welding multiple steel bar frames 1 and multiple steel bar meshes 2, there are two longer steel bar frames 1 among the multiple steel bar frames 1 as the frames on the length of the rectangular steel frame 3; there are also two shorter steel bar frames 1 as the frames on the width of the rectangular steel frame 3; and finally there is a longer steel frame as the bottom frame of the rectangular steel frame 3. In this embodiment, it is preferred to weld a steel bar mesh 2 on the steel bar frame 1 on the width of the rectangular steel frame 3; and two steel bar meshes 2 are welded at intervals on the steel bar frames 1 on the length and the bottom, but the structures of the multiple steel frames are the same except for the different lengths. The following takes the cooperation between the steel bar frame 1 and the steel bar mesh 2 in the length direction of the rectangular steel frame 3 as an example for elaboration.

[0028] Refer to Figure 2 And Figure 3 , The steel bar frame 1 includes horizontal main steel bars 11 and vertical main steel bars 12. The horizontal main steel bars 11 extend in the horizontal direction, the vertical main steel bars 12 extend in the vertical direction, and the vertical main steel bars 12 are positioned and installed on the horizontal main steel bars 11. There are two horizontal main steel bars 11, and the two horizontal main steel bars 11 are spaced and symmetrically arranged along the vertical direction. There are three vertical main steel bars 12, and two of the three vertical main steel bars 12 are respectively located on both sides in the length direction of the horizontal main steel bars 11; and the third one is located in the middle of the horizontal main steel bars 11, that is, the two vertical main steel bars 12 located on both sides in the length direction of the horizontal main steel bars 11 are symmetric about the vertical main steel bar 12 located in the middle of the horizontal main steel bars 11, and the three vertical main steel bars 12 are all located between the two horizontal main steel bars 11. Two steel bar meshes 2 are respectively located between adjacent two vertical main steel bars 12, and the two steel bar meshes 2 are both located between the two horizontal main steel bars 11.

[0029] On the outer wall of the horizontal main reinforcement bar 11 close to the vertical main reinforcement bar 12, a contact plane 111 that fits the end of the vertical main reinforcement bar 12 is ground by a grinding machine. Since three vertical main reinforcement bars 12 are arranged in cooperation with one horizontal main reinforcement bar 11, there are three contact planes 111, and the three contact planes 111 correspond to the three vertical main reinforcement bars 12 one by one. Positioning welding holes 112 are formed in each contact plane 111, and the diameter of the positioning welding holes 112 is smaller than the diameter of the vertical main reinforcement bar 12. Positioning columns 121 are welded to both ends of the vertical main reinforcement bar 12 and inserted into the positioning welding holes 112 to position the vertical main reinforcement bar 12 on the horizontal main reinforcement bar 11. Therefore, when welding the horizontal main reinforcement bar 11 and the vertical main reinforcement bar 12, it is not necessary to hold the vertical main reinforcement bar 12 by hand.

[0030] Combined with Figure 1 Referring to Figure 2 With Figure 3 , assuming that the two positioning columns 121 at both ends of the vertical main reinforcement bar 12 are the top positioning column and the bottom positioning column respectively, the top positioning column is located at one end of the vertical main reinforcement bar 12 close to the opening of the cuboid steel bar frame 3. The length of the top positioning column is longer than that of the bottom positioning column. After the top positioning column is inserted into the corresponding positioning welding hole 112, it will protrude from the corresponding positioning welding hole 112; while after the bottom positioning column is inserted into the corresponding positioning welding hole 112, it will not protrude from the corresponding positioning welding hole 112, and there is a clearance between the end of the bottom positioning column and the other orifice of the corresponding positioning welding hole 112. When multiple cuboid steel bar frames 3 are stacked together, the part of the top positioning column protruding from the corresponding positioning welding hole 112 in the lower cuboid steel bar frame 3 will be inserted into the clearance of the bottom positioning welding hole 112 of the adjacent upper cuboid steel bar frame 3, so that multiple cuboid steel bar frames 3 can be kept neat after being stacked together.

[0031] Referring to Figure 2 With Figure 3, the steel bar mesh 2 is a rectangular mesh made by intersecting and welding multiple steel bars. Multiple connecting steel bars 21 protrude outward from the four peripheral walls of the steel bar mesh 2. Let the connecting steel bars 21 on the two lateral side walls of the steel bar mesh 2 be the lateral connecting steel bars; and the connecting steel bars 21 on the two vertical side walls be the vertical connecting steel bars. A plurality of first positioning grooves 113 for inserting multiple vertical connecting steel bars are formed on the outer wall of the lateral main steel bar 11 (referring to the side where the two opposite steel bar frames 1 face away from each other); a plurality of second positioning grooves 122 for inserting multiple lateral connecting steel bars are formed on the inner wall of the vertical main steel bar 12 (referring to the side where the two opposite steel bar frames 1 are close to each other). After the vertical connecting steel bars are inserted into the first positioning grooves 113, they are positioned and at the same time the contact area with the lateral main steel bar 11 is increased, and thus it is more stable after welding. Similarly, after the lateral connecting steel bars are inserted into the second positioning grooves 122, they are positioned and at the same time the contact area with the vertical main steel bar 12 is increased, and thus it is more stable after welding.

[0032] Combined with Figure 1 Refer to Figure 2 And Figure 3 , angle irons 31 are welded at the four right angles at the top of the cuboid steel bar frame 3 (referring to the open end of the cuboid steel bar frame 3). The two mutually perpendicular inner sides of the angle irons 31 are respectively attached to the outer walls of the two lateral main steel bars 11 at the tops of the two mutually perpendicular steel bar frames 1. Thus, when multiple cuboid steel bar frames 3 are stacked, they can be stacked more neatly under the positioning of the angle irons 31.

[0033] It should be noted that since one steel bar mesh 2 is provided in the steel bar frame 1 in the width direction, only two vertical main steel bars 12 are provided. And the steel bar mesh 2 in the width direction is also located between the two vertical main steel bars 12 and the two lateral main steel bars 11. The structures of the two vertical main steel bars 12 and the two lateral main steel bars 11 are the same as those described above, and will not be elaborated here too much.

[0034] The implementation principle of a steel bar cage retaining wall structure in an embodiment of the present application is as follows: Since the steel bar mesh 2 is a prefabricated part or a purchased part, the steel bar mesh 2 does not need to be made during the welding of the steel bar cage. When welding and processing each steel bar frame 1, the vertical main steel bar 12 can be directly inserted into the positioning welding holes 112 of the lateral main steel bar 11 through the positioning columns 121, and then the circumferential sides of the vertical main steel bar 12 and the lateral main steel bar 11 in contact with each other are welded.

[0035] In addition, when welding the steel bar mesh 2 to the steel bar frame 1, the vertical connecting steel bars can be inserted into the first positioning grooves 113, and the horizontal connecting steel bars can be inserted into the second positioning grooves 122, so that the steel bar mesh 2 is pre-positioned and installed on the steel bar frame. After that, the steel bar mesh 2 can be directly welded. The entire welding process no longer requires welders to measure the positions and hold the steel bars with one hand during welding, thereby improving the convenience of welding the steel bar cage.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
