Description

Technical Field

[0001] The utility model relates to the technical field of lattice beam construction, in particular to a device for controlling the thickness of a steel bar protective layer of a slope lattice beam. Background Art

[0002] In civil engineering, slope stability is a crucial issue. In order to ensure the stability of the slope, a lattice beam structure is usually used to reinforce the slope. A lattice beam is a frame structure composed of steel bars, which can effectively improve the bearing capacity and stability of the soil. In this structure, the thickness of the steel bar cover is a key parameter because it directly affects the durability and corrosion resistance of the structure.

[0003] The patent with announcement number CN211473081U discloses a device for controlling the thickness of the protective layer of the steel bars of the slope lattice beam. The patent uses a bracket to support the steel bar frame, and the position of the bracket is height-adjustable to ensure that the thickness of the protective layer is sufficient during the pouring of concrete, thereby improving the quality of the lattice beam. A limiting portion is provided on the end of the second plate away from the first plate. The limiting portion is arranged on the surface of the second plate supporting the steel bars, and the limiting portion is arranged in the direction of the supporting steel bars to ensure that the steel bars will not slide toward the inside between the two support rods. However, the patent still has the following defects: on the one hand, the support rod and the cross bar are in an "H" shape, and the two support rods are prone to angular deflection, and the device structure has poor stability; on the other hand, the steel bars will be vibrated during the pouring process. Although the use of a limiting portion can prevent the steel bars from sliding off, the vibration generated during the vibration process may also cause the steel bars to slide out.

[0004] In view of this, how to change the current situation that the device has poor stability and the steel bars are easy to slide off the bracket during the pouring process has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0033] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Embodiment 1:

[0035] Reference Figure 1-2 The utility model provides a device for controlling the thickness of the protective layer of the steel bars of the slope lattice beam, comprising a support rod 1, a cross rod 3 and a bracket 4.

[0036] The utility model is provided with two cross bars 3 and two support bars 1, and the two ends of the cross bar 3 are respectively connected to the two support bars 1, and the two ends of the cross bar 3 are respectively abutted against the two support bars 1, which can effectively prevent the two support bars 1 from getting close to or away from each other. When the end of the support bar 1 away from the bracket 4 is inserted into the ground, the angle deflection of the support bar 1 can be effectively reduced to improve the stability of the device.

[0037] The bracket 4 is provided with a locking portion, which is used to lock the steel bar 12 so that the steel bar 12 is connected to the bracket 4 and prevent the steel bar 12 from sliding off the bracket 4 .

[0038] Preferably, the bracket 4 includes a first plate 401 and a second plate 402 which are perpendicular to each other, the first plate 401 and the second plate 402 are connected or integrally formed, the first plate 401 is fixedly and slidably connected to the support rod 1, the second plate 402 is used to support the steel bar 12, and a locking portion is provided on the second plate 402. In a specific embodiment of the utility model, the first plate 401 and the second plate 402 are integrally formed, and the first plate 401 is bent to form the second plate 402.

[0039] Preferably, the locking part includes a first bolt 5, a first nut 7 and a locking rope 6. The first bolt 5 is arranged to penetrate the second plate 402, and the first bolt 5 includes a head and a screw rod; the locking rope 6 is a steel wire rope, and the locking rope 6 penetrates the head of the first bolt 5 and is connected end to end to form a circular ring. After the locking rope 6 away from the head of the first bolt 5 surrounds the circumference of the steel bar 12, the screw rod of the first bolt 5 is inserted into the circular ring enclosed by the locking rope 6 to achieve locking of the steel bar 12. The first bolt 5 penetrates the second plate 402 and is connected with the first nut 7. Through this design, the utility model can lock the steel bar 12 and the second plate 402 together, and the steel bar 12 cannot slide off the second plate 402 by vibration, thereby solving the problem of the steel bar 12 sliding off the bracket 4 during the vibration process.

[0040] In the present invention, the height of the bracket 4 is adjustable, and a mounting slot 2 is provided on the support rod 1, and the mounting slot 2 extends along the length direction of the support rod 1. The present invention also includes a second bolt 10 and a second nut 11, and the second bolt 10 passes through the first plate 401 and the mounting slot 2 in sequence and is connected to the second nut 11. The position of the bracket 4 on the support rod 1 can be adjusted by the second bolt 10 and the second nut 11, and the bracket 4 is adjusted to the set position by loosening the second bolt 10, and then the second bolt 10 is tightened to fix the bracket 4.

[0041] In the utility model, two brackets 4 are fixedly and slidably connected to each support rod 1 , and the two brackets 4 are spaced apart along the length direction of the support rod 1 .

[0042] The method of using this embodiment is as follows: first, dig a trench, insert one end of the support rod 1 into the trench, and then backfill the trench so that one end of the support rod 1 is fixed underground, and the cross bar 3 near one end of the support rod 1 abuts against the ground surface to prevent the support rod 1 from sinking. Secondly, set the device of the utility model at a predetermined interval, then lay the steel bars 12 and form a steel bar frame so that the steel bars 12 are supported on the bracket 4; finally, assemble the template on the outside of the steel bar frame, and embed the steel bar frame and the device into the concrete.

[0043] The device of the present application can fix the steel frame composed of steel bars 12, so that the shape of the steel frame remains consistent, and the position height of the bracket 4 is adjustable to meet the construction of steel frames of different sizes, thereby ensuring that the thickness of the protective layer is sufficient during the pouring of concrete and improving the quality of the lattice beam.

[0044] Embodiment 2:

[0045] Reference Figure 3-5 The difference between this embodiment and the first embodiment is that the structure of the locking part is different.

[0046] Specifically, the locking portion includes an "Ω"-shaped locking ring 8, which is made of a flexible material and can produce a certain deformation. The locking ring 8 is used to surround the circumference of the steel bar 12. The opening of the locking ring 8 faces the top of the second plate 402 and is detachably connected to the second plate 402.

[0047] Preferably, the locking ring 8 includes a semicircular locking ring 801 and extension plates 802 arranged at both ends of the locking ring 801, the locking ring 801 and the extension plates 802 are connected or integrally formed, and the locking ring 801 is used to lock the steel bar 12;

[0048] Two storage cavities 9 are fixedly arranged at intervals along the left-right direction on the upper surface of the second plate 402, and openings are arranged on the opposite side of the two storage cavities 9 and the upward side of the two storage cavities 9. The two extension plates 802 are detachably connected to the two storage cavities 9 in a one-to-one correspondence.

[0049] The use process of the locking part of this embodiment is as follows: first, by pulling the two extension plates 802 in opposite directions, the opening of the locking ring 801 becomes larger; then, the locking ring 801 is put on the steel bar 12, and the pulling of the extension plate 802 is stopped, so that the locking ring 801 returns to its original state; finally, it slides along the axial direction of the steel bar 12, so that the two extension plates 802 are embedded in the storage cavity 9.

[0050] It should be noted that the slope lattice beam is generally arranged at an angle, and the openings on the upper side of the two storage cavities 9 should be arranged toward the top of the slope, so that the extension plate 802 can be embedded in the storage cavity 9 under the action of its own gravity. During the vibration process, when the steel bar 12 moves along its axial direction due to vibration, relative sliding can occur between the steel bar 12 and the locking ring 801, and the steel bar 12 can be restricted from moving along its radial direction, thereby further achieving the locking effect of the steel bar 12. Compared with the first embodiment, this embodiment is more convenient to install.

[0051] The method of use of this embodiment is the same as that of the first embodiment, and will not be repeated here.

[0052] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0053] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
