Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a double-layer steel bar mesh support frame. Background Art

[0002] In modern transportation industry, shipping occupies an important position. During the shipping process, ship locks are indispensable. When ships pass through the ship locks, the lock head and the lock chamber need to bear large forces. Therefore, in order to ensure the structural strength of the lock chamber, double-layer steel bar meshes are adopted for the lock body and the bottom of the ship lock, and concrete is poured to achieve the effect of strengthening the structural strength. During construction, the spacing between the two layers of steel bar meshes and the distance between the steel bars on the same layer of steel bar mesh need to be accurately controlled to achieve the preset stress effect. At present, the adopted method is to set a plurality of precast concrete pads between the formwork and the steel bar mesh, and between the steel bar meshes. The distance between the steel bar meshes and between the steel bar mesh and the formwork is controlled by using a plurality of concrete pads. The spacing between the double-layer steel bar meshes is adjusted by selecting concrete pads of different sizes, and finally different stress effects are achieved. However, in actual use, the concrete pads are prone to sag due to their own weight and deviate from the original position, and are also prone to looseness when subjected to external forces, resulting in inaccurate positioning between the double-layer steel bar meshes and between the steel bar mesh and the formwork.

[0003] As can be seen from the above, there is a problem in the prior art that the double-layer steel bar mesh cannot be accurately positioned during construction. Summary of the Utility Model

The extending direction of the second positioning plate is perpendicular to the extending direction of the first positioning plate, and the second positioning plate abuts against the first positioning plate.

[0010] Further, both the first positioning plate and the second positioning plate are provided with positioning grooves for positioning the steel bar mesh. The first positioning plate is provided with an avoidance groove for avoiding the second positioning plate.

[0011] Further, the positioning groove is trapezoidal, and the opening of the positioning groove decreases along the direction away from the steel bar mesh.

[0025] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0026] It should be pointed out that unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0027] In the present utility model, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are usually in reference to the direction shown in the drawings, or in reference to the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation words do not limit the present utility model.

[0028] Obviously, the above-described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] In order to solve the problem that the double-layer steel bar mesh cannot be accurately positioned during construction in the prior art, the present utility model provides a double-layer steel bar mesh support frame.

[0030] Such as Figures 1 to 6As shown in the figure, the double-layer steel bar mesh support frame includes a first support rod 10, a first positioning plate 20 and a support member 30. The first support rod 10 is used to connect the formwork. There are at least two first positioning plates 20. The two first positioning plates 20 are arranged at intervals. The first support rod 10 passes through the two first positioning plates 20 in sequence. The first positioning plate 20 is used to position the steel bar mesh 70. There are multiple support members 30. Multiple support members 30 are grouped in pairs. A part of multiple groups of support members 30 is arranged on the first support rod 10 at intervals. One support member 30 in a group of support members 30 abuts against the side of the first positioning plate 20 away from the steel bar mesh 70, and the other support member 30 in a group of support members 30 abuts against the side of the steel bar mesh 70 away from the first positioning plate 20, for supporting the steel bar mesh 70.

[0031] By arranging two first positioning plates 20 to initially position the two steel bar meshes 70 respectively, a part of multiple groups of support members 30 is arranged on the first support rod 10. Two support members 30 are arranged on the first support rod 10 and a first positioning plate 20 and a steel bar mesh 70 are arranged between the two support members 30. Adjusting the distance between the two support members 30 enables the two support members 30 to clamp the first positioning plate 20 and the steel bar mesh 70, ensuring that the steel bar mesh 70 is accurately positioned on the first positioning plate 20 during the entire construction process. By using two first positioning plates 20 arranged on one first support rod 10 and correspondingly arranging two groups of a group of support members 30, the positioning and clamping of the two steel bar meshes 70 are realized, and the position of the steel bar mesh 70 is fixed and the distance between the two steel bar meshes 70 remains unchanged during the entire construction process, thereby improving the accuracy of the positioning of the double-layer steel bar mesh during construction.

[0032] In this embodiment, there are multiple first support rods 10, and the multiple first support rods 10 are arranged at intervals on the first positioning plate 20.

[0033] Specifically, the stability of the first positioning plate 20 is improved by arranging multiple first support rods 10 on the first positioning plate 20. In this embodiment, a backing plate 80 is arranged at one end of the first support rod 10 away from the first positioning plate 20. During actual construction, the connection between the first support rod 10 and the formwork 90 is realized by connecting the backing plate 80 with the inner wall of the formwork 90. Optionally, the formwork 90 is a bottom plate or a side plate, and the axial direction of the first support rod 10 is reasonably set according to actual needs to realize the pouring of the lock wall and the bottom plate.

[0034] In this embodiment, the multiple first support rods 10 are arranged at intervals along the length direction of the first positioning plate 20.

[0035] Such as Figure 6As shown, the double-layer steel bar mesh support frame further includes a second support rod 40. The second support rod 40 sequentially passes through two first positioning plates 20, and the other parts of multiple groups of support members 30 are spaced apart on the second support rod 40. One group of support members 30 are respectively arranged on both sides of the first positioning plate 20 for supporting the first positioning plate 20.

[0036] Specifically, the second support rod 40 sequentially passes through two first positioning plates, and the other parts of multiple groups of support members 30 are sleeved on the second support rod 40 at intervals. It can be understood that one part of multiple groups of support members 30 is arranged on the first support rod 10, and the other part is arranged on the second support rod 40. For example, for 34 groups of support members 30, 18 groups are arranged on the first support rod 10 and 16 groups are arranged on the second support rod 40.

[0037] In this embodiment, two groups of support members 30 are arranged on the first support rod 10, and the two groups of support members 30 respectively correspond to two first positioning plates 20. One group of support members 30 arranged on the first support rod 10 is used to fasten the first positioning plate 20 and the steel bar mesh 70. The two support members 30 on the second support rod 40 are attached to both sides of the first positioning plate 20. The cooperation of the support members 30 with the first support rod 10 and the second support rod 40 can improve the pressure-bearing capacity of the first positioning plate 20.

[0038] In this embodiment, there are multiple second support rods 40, and multiple second support rods 40 are spaced between any two first support rods 10.

[0039] Specifically, the multiple second support rods 40 are spaced along the length direction of the first positioning plate 20, and multiple second support rods 40 with the same interval are spaced between two first support rods 10.

[0040] As Figures 3 to 6 shown, the double-layer steel bar mesh support frame further includes a second positioning plate 50. The extending direction of the second positioning plate 50 is perpendicular to the extending direction of the first positioning plate 20, and the second positioning plate 50 abuts against the first positioning plate 20.

[0041] Specifically, the second positioning plate 50 is perpendicular to the first positioning plate 20 and abuts on the first positioning plate 20. The first positioning plate 20 and the second positioning plate 50 form a cross-shaped structure to position and support the entire steel bar mesh 70, thereby increasing the contact area between the double-layer steel bar mesh support frame and the steel bar mesh 70.

[0042] As Figure 3 and Figure 6 shown, both the first positioning plate 20 and the second positioning plate 50 are provided with positioning grooves 60 for positioning the steel bar mesh 70. The first positioning plate 20 is provided with an avoidance groove 21 for avoiding the second positioning plate 50.

[0043] Specifically, there are multiple positioning grooves 60 and avoiding grooves 21. The multiple positioning grooves 60 are arranged at intervals along the length direction of the first positioning plate 20 and the second positioning plate 50. The steel bar mesh 70 includes longitudinal steel bars and transverse steel bars, and the longitudinal steel bars are perpendicular to the transverse steel bars. The longitudinal steel bars are received in the positioning grooves 60 on the first positioning plate 20, and the transverse steel bars are received in the positioning grooves 60 of the second positioning plate 50, thereby realizing the positioning of the steel bar mesh 70.

[0044] In this embodiment, the positioning groove 60 is trapezoidal, and the opening of the positioning groove 60 decreases in the direction away from the steel bar mesh 70.

[0045] Specifically, the cross-section of the positioning groove 60 is an inverted trapezoid. This setting method can facilitate the transverse steel bars or longitudinal steel bars on the steel bar mesh 70 to fall into the positioning groove 60. At the same time, the trapezoidal groove structure can provide a large supporting force for the steel bar mesh 70. At the same time, the way the steel bar mesh 70 is arranged in the positioning groove 60 is not conducive to the movement of the steel bar mesh 70 in the positioning groove 60, so as to fix the position of the steel bar mesh 70 during construction.

[0046] In this embodiment, both the first positioning plate 20 and the second positioning plate 50 are angle steels. The cutting angle of the positioning groove 60 is between 45° and 60°, and the diameter of the bottom of the positioning groove 60 is between 0.7 times and 0.8 times the diameter of the steel bars on the steel bar mesh 70. The cutting angle and the opening size of the bottom of the groove can be processed according to actual needs.

[0047] In this embodiment, there are multiple second positioning plates 50 and avoiding grooves 21. The multiple avoiding grooves 21 are arranged at intervals on the first positioning plate 20, and the multiple second positioning plates 50 are arranged in one-to-one correspondence with the multiple avoiding grooves 21.

[0048] Specifically, the avoiding grooves 21 on the multiple first positioning plates 20 are rectangular grooves, and the avoiding grooves 21 are adapted to the second positioning plates 50 to prevent the second positioning plates 50 from shaking in the avoiding grooves 21.

[0049] In this embodiment, the extending directions of the two first positioning plates 20 provided on the same first support rod 10 are parallel.

[0050] In another embodiment not shown in this application, the extending directions of the two first positioning plates 20 provided on the same first support rod 10 are perpendicular.

[0051] In this embodiment, the multiple second positioning plates 50 are arranged at intervals in pairs, and the multiple first support rods 10 and the multiple second support rods 40 are all inserted through a group of second positioning plates 50.

[0052] Specifically, the two second positioning plates 50 of each group are spaced vertically. Multiple first support rods 10 and second support rods 40 are also provided on the second positioning plates 50. The first support rods 10 and the second support rods 40 are used to support the second positioning plates 50. Optionally, the first support rods 10 and the second support rods 40 are not provided on the second positioning plates 50.

[0053] In this embodiment, the difference between the second positioning plate 50 and the first positioning plate 20 is that an avoidance groove 21 is formed on the first positioning plate 20 to distinguish the first positioning plate 20 from the second positioning plate 50, so as to improve the assembly efficiency of the double-layer steel bar mesh support frame.

[0054] In another embodiment (not shown) of the present application, the second positioning plate 50 is exactly the same as the first positioning plate 20, which is convenient for processing and improves production efficiency.

[0055] In this embodiment, the support member 30 is a nut and the first support rod 10 is a threaded rod.

[0056] Specifically, threaded sections are provided on both the first support rod 10 and the second support rod 40. The support member 30 is a self-locking nut. By adjusting the position of the support member 30 on the first support rod 10 and the second support rod 40, the distance between the two steel bar meshes 70 and the distance between the steel bar mesh 70 and the formwork 90 are adjusted, so that the post-construction reinforced concrete structure has better structural strength.

[0057] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: The double-layer steel bar mesh support frame includes a first support rod 10, a first positioning plate 20 and a support member 30. The first support rod 10 is used to connect the formwork. There are at least two first positioning plates 20, and the two first positioning plates 20 are arranged at intervals. The first support rod 10 sequentially passes through the two first positioning plates 20. The first positioning plate 20 is used to position the steel bar mesh 70. There are multiple support members 30, and multiple support members 30 are grouped in pairs. A part of multiple groups of support members 30 is arranged at intervals on the first support rod 10. One support member 30 in a group of support members 30 abuts against the side of the first positioning plate 20 away from the steel bar mesh 70, and the other support member 30 in a group of support members 30 abuts against the side of the steel bar mesh 70 away from the first positioning plate 20, for supporting the steel bar mesh 70. By providing two first positioning plates 20 to initially position the two steel bar meshes 70 respectively, a part of multiple groups of support members 30 is arranged on the first support rod 10. Two support members 30 are arranged on the first support rod 10, and a first positioning plate 20 and a steel bar mesh 70 are arranged between the two support members 30. Adjusting the distance between the two support members 30 enables the two support members 30 to clamp the first positioning plate 20 and the steel bar mesh 70, ensuring that the steel bar mesh 70 is accurately positioned on the first positioning plate 20 throughout the construction process. By using two first positioning plates 20 provided on one first support rod 10 and correspondingly arranging two groups of a group of support members 30, the positioning and clamping of the two steel bar meshes 70 are realized, and the position of the steel bar mesh 70 is fixed and the distance between the two steel bar meshes 70 remains unchanged throughout the construction process, thereby improving the accuracy of the positioning of the double-layer steel bar mesh during construction.
