A type of asphalt intermediate and lower layer leveling support

Abstract

This application relates to a leveling support for the middle and lower layers of asphalt, belonging to the technical field of asphalt construction. The leveling support includes: a fixed base plate; a support panel, elliptically mounted on the fixed base plate for supporting a steel wire rope; and an adjusting component installed on the fixed base plate for adjusting the height of the support panel. During leveling, the height of the support panel can be adjusted using the adjusting component to change the height of the steel wire rope, ensuring the wire rope reaches the designed loose paving height and reducing paving thickness errors. Since there is no need to find temporary bricks, wood chips, or similar items on-site, only the leveling support needs to be carried to adjust the steel wire rope, thus facilitating the leveling of the middle and lower layers.

Description

Technical Field

[0001] This application relates to the technical field of asphalt construction, and in particular to a leveling support for the middle and lower layers of asphalt. Background Technology

[0002] During the paving of the lower layer in asphalt construction, steel wire ropes are needed for leveling. As the steel wire ropes sag to varying degrees due to gravity during tensioning, the sag becomes more pronounced closer to the center. As a result, the flatness of the lower and middle layers is often poor. Therefore, it is often necessary to use temporary bricks, wood chips, or similar items found on-site to support the steel wire ropes at the measured elevation points to the designed paving height, making the leveling of the lower and middle layers quite troublesome. Utility Model Content

[0003] To facilitate the leveling of the middle and lower layers of asphalt, this application provides a leveling support for the middle and lower layers of asphalt, employing the following technical solution:

[0004] A leveling support for the lower layer of asphalt, comprising:

[0005] Fixed base plate;

[0006] A support panel, which is raised and lowered on the fixed base plate, is used to support the steel wire rope;

[0007] An adjustment component, mounted on the fixed base plate, is used to adjust the height of the support panel.

[0008] By adopting the above technical solution, during leveling, the height of the support panel can be adjusted by adjusting the components to change the height of the wire rope, so that the height of the wire rope reaches the designed loose laying height, thereby reducing the error of the paving thickness. Since there is no need to find temporary bricks, wood chips or other items on site, only leveling supports need to be carried to adjust the wire rope, thus facilitating the leveling of the middle and lower layers.

[0009] Optionally, the support panel is arranged parallel to the fixed base plate.

[0010] By adopting the above technical solution, the support area of ​​the wire rope can be increased.

[0011] Optionally, the adjustment component includes:

[0012] Support rods are respectively disposed on both sides of the fixed base plate; the two ends of the support rods are respectively hinged to the support panel and the fixed base plate through hinge shafts;

[0013] An adjusting plate is hinged to the supporting panel and the fixed base plate;

[0014] The adjusting bolt is threadedly connected to the adjusting plate and abuts against the fixed base plate.

[0015] By adopting the above technical solution, rotating the adjusting bolt will cause the adjusting plate to move the supporting panel, thereby adjusting the height of the supporting panel.

[0016] Optionally, the fixed base plate has a length of 25cm and a width of 4cm-5cm; the projection of the upper plane of the support panel is located on the fixed base plate.

[0017] By adopting the above technical solution, the leveling support is made easy to carry.

[0018] Optionally, the height adjustment range of the support panel is 3mm-11mm.

[0019] By adopting the above technical solutions, the working requirements for the construction of the middle and lower layers can be basically met.

[0020] Optionally, a lifting rope is installed on the fixed base plate.

[0021] By adopting the above technical solution, it is even more convenient to carry the leveling support.

[0022] Optionally, the support panel is provided with support markings.

[0023] By adopting the above technical solution, when multiple leveling supports are used to support the wire rope, the support position is within the deviation error, and the placement of multiple leveling supports is easy to align, which facilitates subsequent construction.

[0024] In summary, this application has at least the following beneficial effects:

[0025] 1. During leveling, the height of the support panel can be adjusted by adjusting the components to accurately adjust the height of the wire rope, so that the height of the wire rope reaches the designed loose laying height, thereby reducing the error of the paving thickness and greatly improving the flatness of the lower layer during paving.

[0026] 2. The leveling support is easy to carry, quick to adjust, and can be used repeatedly. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the appendices of the embodiments of this utility model will be described below. Figure 1 -Appendix Figure 2 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] This application discloses a leveling support for the lower layer of asphalt. One embodiment of the leveling support is as follows: (Refer to...) Figure 1 The leveling support may include a fixed base plate 110, a support panel 120, and an adjusting component 130. The fixed base plate 110 is 25cm long and 4-5cm wide. The support panel 120 is parallel to the fixed base plate 110, and its upper surface projection is located on the fixed base plate 110. It is also mounted on the fixed base plate 110 to support the wire rope 200. The adjusting component 130 is installed on the fixed base plate 110 and is used to adjust the height of the support panel 120.

[0032] The adjusting component 130 may include a support rod 131, an adjusting plate 132, and an adjusting bolt 133. The support rod 131 is located on both sides of the fixed base plate 110, and its two ends are hinged to the support panel 120 and the fixed base plate 110 respectively via hinge shafts. The adjusting plate 132 is hinged to both the support panel 120 and the fixed base plate 110 respectively. The adjusting bolt 133 is threadedly connected to the adjusting plate 132 and abuts against the fixed base plate 110. Rotating the adjusting bolt 133 causes the adjusting plate 132 to move the support panel 120. The height adjustment range of the support panel 120 is 3mm-11mm.

[0033] Furthermore, the support panel 120 is also provided with support marks, which can be marking lines or support grooves opened on the support panel 120.

[0034] Another implementation method for the leveling support is as follows: Figure 2 Pull rings 111 are welded to both sides of the fixed base plate 110, and the lifting rope 134 is attached to the pull rings 111.

[0035] The implementation principle of this embodiment is as follows:

[0036] When adjusting the wire rope 200, one worker places the leveling support under the wire rope 200 and then rotates the adjusting bolt 133, causing the adjusting plate 132 to lift the support panel 120 to adjust the height of the wire rope 200; another worker measures the height of the wire rope 200 with a tape measure. After the height of the wire rope 200 reaches the specified height, the worker stops rotating the adjusting bolt 133 to complete the adjustment.

[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Any feature disclosed in this specification (including the abstract and drawings) may be replaced by other equivalent or similar features unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is only one example of a series of equivalent or similar features.
