Description

Technical Field

[0001] This utility model relates to the field of road construction auxiliary tools, and in particular to a double-sided steel formwork for concrete pavement. Background Technology

[0002] In the construction of cement concrete pavements, steel formwork is often used for support. This type of formwork has only one working surface, and its width is fixed; the width of the formwork is also called its height. When the concrete pavement has different thicknesses, it is necessary to replace it with steel formwork of different widths, thus increasing the number of steel formwork units required.

[0003] In addition, when transverse dowel bars and tie bars are designed in the construction process of concrete roads, holes need to be made in the steel formwork, which is troublesome and inefficient to implement.

[0004] A search revealed Chinese patent document CN207047668U, published on February 27, 2018, which discloses a triangular fixing frame for steel formwork. This triangular fixing frame includes a steel formwork with a channel steel structure. The formwork includes a web in the middle and wing plates on both sides. It also includes a fixing frame, which comprises sleeve one, sleeve two, connecting rods, and a steel rod. Two sleeves one are fixed near each end of the web of the steel formwork, and the axes of the four sleeves one are parallel to each other and parallel to the width direction of the web. The front end of the connecting rod is bent at an angle to form a hook, and sleeve two is welded to the rear end. The hook is inserted into sleeve one from the top end of sleeve one, fixing the connecting rod to sleeve one. The sleeve two at the rear ends of the two connecting rods connected to the two adjacent sleeves one overlap and are together fitted into a steel rod, with the axis of the steel rod parallel to the axis of sleeve one. Its features are: this fixing frame can effectively improve the reinforcement efficiency of steel formwork for road base; its shortcomings are: first, the height of the steel formwork is fixed and cannot adapt to different concrete pouring heights; second, when there are transverse dowel bars and tie bars in the concrete road construction process, holes need to be made in the steel formwork; third, although this structure reduces the number of steel chisels, connecting rods still need to be installed during the installation process, which not only increases the accessories but also makes the installation operation more complicated. Utility Model Content

[0005] The technical problem this invention aims to solve is to address the issues existing in the background art by providing a double-sided steel formwork for concrete pavements. The formwork is designed with a triangular structure, where the widths of the first and second support plates differ to accommodate two different concrete pouring heights.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0032] Example 1:

[0033] See Figure 1-4 A double-sided steel formwork for concrete pavement includes a first support plate 10, a second support plate 20, and an end plate 30. The second support plate 20 is fixed to one end of the first support plate 10 in the width direction. The first support plate 10 and the second support plate 20 have the same length but different widths. The two end plates 30 are respectively fixed to the two ends of the first support plate 10 and the second support plate 20. The first support plate 10, the second support plate 20, and the end plate 30 form a triangular structure. The first support plate 10 is provided with a plurality of first mounting holes 11 along the length direction, and the second support plate 20 is provided with a plurality of second mounting holes 21 along the length direction.

[0034] This utility model designs the steel formwork into a triangular structure, with the first support plate 10 and the second support plate 20 of the triangular structure having different widths, thus accommodating two different concrete pouring heights. The first support plate 10 has multiple first mounting holes 11 along its length, and the second support plate 20 has multiple second mounting holes 21 along its length. The first mounting holes 11 and the second mounting holes 21 can be used to install dowel bars, tie rods, and steel rods as needed. This utility model has a simple structure; during installation, steel rods can be directly driven in, making the installation operation much simpler.

[0035] Specifically, such as Figure 1 As shown, the second mounting hole 21 is used for the force transmission rod and the tie rod to pass through, and the first mounting hole 11 is used for driving in the steel rod.

[0036] Further, see Figure 1 , 2The second support plate 20 has a first concave structure 22 along its length, which forms a groove on the end face of the second support plate 20. This structure not only improves the structural strength of the second support plate 20, but also facilitates the interlocking of adjacent concrete interfaces. The overall integrity of the poured concrete is better than that of concrete poured with a flat formwork, reducing vertical displacement under vehicle load at the interface of adjacent concrete and adapting to heavy traffic.

[0037] Specifically, the first concave structure 22 is an arc-shaped structure or a trapezoidal structure. The width of the opening of the groove is greater than the internal width to facilitate demolding.

[0038] In this embodiment, the second mounting hole 21 is located on the first recessed structure 22.

[0039] Furthermore, the first support plate 10 is provided with a second concave structure 12 along its length, the second concave structure 12 forming a groove on the bottom surface of the first support plate 10; the first mounting hole 11 is located on the second concave structure 12 for bidirectional use.

[0040] Specifically, the second concave structure 12 is an arc-shaped structure or a trapezoidal structure. Similarly, the width of the groove opening is greater than the internal width, which facilitates demolding.

[0041] See Figure 1 The end plate 30 is provided with multiple docking holes 31 so that multiple steel templates can be connected in series by bolts, resulting in better overall integrity.

[0042] Furthermore, to improve the overall structural strength of the steel formwork, see [link / reference needed]. Figure 1 Multiple support plates 40 are welded between the first support plate 10 and the second support plate 20 located on both sides of the end plate 30.

[0043] See Figure 1 The first support plate 10 has a first wing plate 13 extending outward at the end away from the second support plate 20, and the second support plate 20 has a second wing plate 23 extending inward at the end away from the first support plate 10, thereby improving the structural strength of the first support plate 10 and the second support plate 20. During vibration, a vibratory pump can be placed on the first wing plate 13 or the second wing plate 23, and vibration can be performed in the same direction.

[0044] Example 2:

[0045] Based on Example 1, see Figure 3 , 4Both the end plate 30 and the support plate 40 are provided with limit slots 50, or only the support plate 40 is provided with limit slots 50. During installation, the limit slots 50 are used to place the support rods 60. After the steel rods 70 are driven in, the steel rods 70 abut against the support rods 60, and the support rods 60 support the upper end of the second support plate 20.

[0046] It should be noted that the height of the limiting slot 50 should be higher than the height of the mounting hole on the corresponding side, so that the support rod 60 will not interfere with the mounting hole.

[0047] exist Figure 3 In this diagram, because the second support plate 20 is wider (i.e., taller) and the first support plate 10 is narrower, only a solution is shown where the end plate 30 and support plate 40 have limiting slots 50 on the side of the second support plate 20. Of course, limiting slots 50 can also be provided on the end plate 30 and support plate 40 on the side of the first support plate 10.

[0048] When using this utility model, please refer to Figure 4 The steel template is placed in the designated position, and multiple steel rods 70 are driven into the foundation after being inserted into the first mounting hole 11. The first mounting hole 11 is used to install force transmission rods and tie rods as needed. To improve stability, support rods 60 can also be inserted into the limiting slot 50.

[0049] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Any modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
