Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a universal template for road asphalt surface layer construction. Background Technology

[0002] The general formwork for road asphalt surface construction typically includes components such as the foundation surface, vertical slabs, and formwork.

[0003] The foundation surface, as the basis for construction, needs to be flat and stable to ensure the smooth progress of subsequent construction. The uprights are placed vertically on both sides of the foundation surface to support and fix the formwork. The formwork is installed on the uprights to form the construction framework of the asphalt surface layer. Some formwork can change the construction height and thickness by adjusting the connection between the uprights and the formwork. However, due to the limitation of the length of the formwork itself, it needs to be moved. Since there are no moving auxiliary parts on both sides of the uprights, they can only be lifted and moved manually. However, continuous lifting can easily affect the convenience and practical effect of its use.

[0004] Therefore, we provide a universal template for road asphalt surface layer construction. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a universal template for road asphalt surface construction, which achieves the effects of rolling support and convenient movement.

[0006] In view of this, the present invention provides a universal template for road asphalt surface construction, including a foundation base, an L-shaped vertical plate, and a template. The L-shaped vertical plate is installed on the upper surface of the foundation base, and the template is installed between the two L-shaped vertical plates. Several support grooves are provided through the horizontal portions of the L-shaped vertical plates on opposite sides. A support shaft is rotatably installed on the inner wall of the support groove. A rotating cylinder is sleeved on the outer side of the support shaft. A connecting arm is installed on the outer side of the rotating cylinder. A connecting frame is installed at the end of the connecting arm away from the rotating cylinder. A roller for rolling support is installed in the middle of the connecting frame. A connecting plate is installed on the outer side of the rotating cylinder. A positioning plate for positioning support is installed at the end of the connecting plate away from the rotating cylinder.

[0007] Preferably, the connecting arm and the connecting plate are at a certain angle, and the angle is 100°~160°.

[0008] Preferably, the upper half of the connecting frame is inserted through the middle of the connecting arm, and the connecting frame has arc-shaped support arms symmetrically distributed on both sides.

[0009] Preferably, a support plate is provided between the two ends of the two arc-shaped support arms, and the support plate is connected to the outer end face of the arc-shaped support arm through a support rod.

[0010] Preferably, a connecting shaft runs through the two support discs, the roller is rotatably sleeved on the outside of the connecting shaft, and the roller is located between the two support discs.

[0011] Preferably, a plurality of positioning support plates are installed on the side surface of the L-shaped upright plate, and two positioning support plates located in opposite positions form a group for operation, and two positioning support plates located at different heights and at different angles are provided on the same side.

[0012] Preferably, both the positioning support plate and the connecting plate are provided with positioning holes, and positioning bolts are connected to the positioning support plate and the connecting plate through the positioning holes.

[0013] Compared with the prior art, this utility model provides a universal template for road asphalt surface layer construction, which has the following beneficial effects:

[0014] 1. This utility model sets a certain angle between the installation positions of the connecting arm and the connecting plate, so that the roller and the positioning plate simultaneously form a certain angle. By moving the positioning plate, the roller can be driven to move synchronously. Within the limitation of this angle range, the roller can promptly disengage from the rolling support state while the movement angle is not large, making the movement range of the roller more controllable.

[0015] 2. With the positioning bolts securing the connecting plate and the upper positioning support plate, the position of the connecting plate and the positioning plate is fixed in the moving state, and the rotation of the rotating cylinder is limited, ensuring the stability of the roller's position during rolling use.

[0016] 3. With the positioning bolts securing the connecting plate and the lower positioning support plate, the connection plate and positioning plate are kept securely in use, preventing the rotating cylinder from rotating and improving the stability of the connection between the positioning plate and the foundation surface.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: A universal template for road asphalt surface layer construction, such as Figure 1 - Figure 5 As shown, the structure includes a foundation surface 1, an L-shaped vertical plate 2, and a template 3. The L-shaped vertical plate 2 is installed on the upper surface of the foundation surface 1, and the template 3 is installed between the two L-shaped vertical plates 2. Several support grooves 4 are provided through the horizontal portions of the L-shaped vertical plates 2 on opposite sides. A support shaft 5 is rotatably installed on the inner wall of the support groove 4. A rotating cylinder 6 is sleeved on the outer side of the support shaft 5. A connecting arm 7 is installed on the outer side of the rotating cylinder 6. A connecting frame 8 is installed at the end of the connecting arm 7 away from the rotating cylinder 6. A roller 11 for rolling support is installed in the middle of the connecting frame 8. A connecting plate 12 is installed on the outer side of the rotating cylinder 6. A positioning plate 13 for positioning support is installed at the end of the connecting plate 12 away from the rotating cylinder 6.

[0027] After the device is moved to the usage position, the operator manually adjusts the rotation of the positioning plate 13, causing the connecting plate 12 and the rotating cylinder 6 to rotate under the connection of the support shaft 5, and gradually moving the positioning plate 13 horizontally. Under the connection and support of the connecting arm 7 and the connecting frame 8, the roller 11 rotates synchronously, and the rotation direction of the roller 11 is consistent with that of the positioning plate 13, so that it gradually moves from the lower half to the upper half inside the support groove 4, and finally the roller 11 is released from the contact state with the upper surface of the foundation base 1. Then, the outer fastening screw is used to fix the positioning plate 13 in position, so that the device is in a stable usage state. The number and position of the template 3 can be selected according to the actual processing requirements to form an adjustable processing specification. Since the specific adjustment method is existing technology, it is not described in detail in this embodiment.

[0028] like Figure 1 - Figure 5 As shown, the connecting arm 7 and the connecting plate 12 are at a certain angle, and the angle is 100°~160°.

[0029] By setting a certain angle between the installation positions of the connecting arm 7 and the connecting plate 12, the roller 11 and the positioning plate 13 simultaneously form a certain angle. By moving the positioning plate 13, the roller 11 can be driven to move synchronously. Within the limitation of this angle range, the roller 11 can disengage from the rolling support state in time while the movement angle is not large, making the movement range of the roller 11 more controllable.

[0030] like Figure 1 - Figure 5 As shown, the upper half of the connecting frame 8 is inserted through the middle of the connecting arm 7, and the connecting frame 8 has arc-shaped support arms that are symmetrically distributed on both sides.

[0031] A support plate 9 is provided between the two ends of the two arc-shaped support arms. The support plate 9 is connected to the outer end face of the arc-shaped support arm through a support rod.

[0032] A connecting shaft 10 passes through the two support plates 9, and a roller 11 is rotatably sleeved on the outside of the connecting shaft 10, with the roller 11 located between the two support plates 9.

[0033] Based on the combined connection of connecting arm 7 and connecting frame 8, rotational support is provided for support plate 9, so that the two side support plates 9 and connecting shaft 10 can provide stable rotational support for roller 11, ensuring efficient and stable operation of roller 11 during rolling support and position adjustment.

[0034] like Figure 1 - Figure 5As shown, several positioning support plates 14 are installed on the side surface of the L-shaped upright plate 2, and two positioning support plates 14 located in opposite positions form a group. Two positioning support plates 14 located at different heights and at different angles are set on the same side.

[0035] Positioning holes are provided through the positioning support plate 14 and the connecting plate 12, and positioning bolts 15 are connected to the positioning support plate 14 and the connecting plate 12 through the positioning holes.

[0036] With the positioning bolt 15 securing the connecting plate 12 and the upper positioning support plate 14, the positions of the connecting plate 12 and the positioning plate 13 are fixed in the moving state, and the rotation of the rotating cylinder 6 is limited, ensuring the stability of the position of the roller 11 during rolling use. With the positioning bolt 15 securing the connecting plate 12 and the lower positioning support plate 14, the connection plate 12 and the positioning plate 13 are secured and stable in the use state, preventing the rotating cylinder 6 from rotating and improving the stability of the connection between the positioning plate 13 and the foundation surface 1.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
