Abstract

(57) [Summary] [Purpose] In asphalt and concrete floor construction, leveling equipment for pavement is used. The leveling surface may be inclined to guide rainwater or water leakage. Such leveling is performed by using a level separately or by leveling while tilting according to a sign board or the like installed horizontally. Therefore, it is not known what the inclination of the work surface is. In view of the above, the present invention is designed to improve the work efficiency by making it possible to recognize how the currently leveled surface is inclined. [Structure] A leveling plate attached in a T-shape directly or via a mounting seat to the tip side of a relatively long handle portion, and is a handle of a pavement leveling tool for finishing asphalt and concrete surfaces to a flat surface. , And a level corresponding to the lower edge of the leveling plate is attached to a part of the handle.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 It is widely used by civil engineering companies, pavement companies such as roads, and those who manufacture and sell paving equipment.Particularly, the slope of the asphalt or concrete finish is actively formed to prevent rainwater or water leakage. This prevents the stagnation and allows the user of the leveling tool to always recognize and identify the inclination of the leveling edge of the leveling plate with the handle.

[0002]

[Prior art]

 For asphalt pavement such as roads, it is necessary to form roads attached to both ends at the both ends and to smooth out the surface without unevenness before pressing the heavy equipment rollers. When leveling asphalt or concrete, a rake-type leveling tool with a T-shaped leveling plate attached to the tip of a long operation pattern is used. In addition, these leveling surfaces may be inclined to actively guide rainwater or leakage. In the past, the inclination was simply formed with a sense, or the inclination was measured and formed by applying a separately prepared level.However, there are many fluctuations depending on the installer, and it is necessary to take the trouble of preparing and leveling the level separately. there were.

[0003]

[Problems to be solved by the invention]

 Therefore, the present invention makes it possible to recognize the horizontality of the lower edge leveling edge line of the leveling plate attached to the tip side only by holding the handle of the leveling tool, and to perform the leveling operation while performing the leveling operation. By making it possible to accurately know the slope of the leveling surface, the construction can be performed while easily recognizing the slope for treating rainwater and water leakage.

[0004]

[Means for Solving the Problems]

 That is, a part of the handle of a pavement leveling tool that finishes the asphalt or concrete surface to a flat surface with a leveling plate attached directly or through a mounting seat in a T-shape to the tip side of a relatively long handle, A level corresponding to the leveling line of the lower edge of the leveling plate is attached, and the level of the leveling surface can be recognized by looking at the level.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the drawings, but the drawings show an example of a specific implementation of the present invention, and the present invention is not limited to the illustrated example, and some parts are in accordance with the purpose described below. Even if the shape is changed or a part of the structure is changed, the present invention can be similarly implemented.

FIG. 1 (partially cutaway plan view) and FIG. 2 (right side view of FIG. 1) show the present invention applied to an asphalt pavement leveling tool 1 shown as an example. In these figures, the exemplary leveling tool 1 attaches a relatively long handle 4 to a substantially triangular mounting seat 3, and the front bent portion of the mounting seat 3 includes arms protruding left and right. The leveling plate 2 is screwed to this surface, and the front surface is formed as a flat surface. The lower edge 2a of the leveling plate 2 moves the handle 4 in the handle axis direction to form a surface. As the handle 4, a light metal pipe having an elliptical cross section is shown, but it may be a double-structure telescopic handle that can be fixed at an appropriate length or a wood handle. . As a specific example of the mounting seat 3, the handle 4 can be securely fixed, the leveling plate mounting surface is formed substantially at right angles to the handle, and the leveling plate 2 is replaceable. As far as possible, various mounting seats can be used. Further, as the leveling plate 2, a wooden plate frequently used is shown, but a metal plate may be used.

Reference numeral 5 denotes a level device. In the illustrated example, the level device is fixedly provided on the handle 4 at the hand side and on the upper surface side of the handle 4. The level of the lower edge 2a of the leveling plate 2 at the tip of the handle 4 is fixed by fixing the handle 4 at an appropriate position, or by disposing a level in the handle 4 and pulling out or pushing it out. You may comprise so that identification is possible.

FIG. 3 (enlarged plan view of the dashed line A portion in FIG. 1) FIG. 4 (right side view in FIG. 3) and FIG. 5 (right side view in FIG. 4) are leveling tools exemplified in FIGS. 1 shows a level device 5 applied to FIG. As shown in FIG. 5, the handle 4 is a light metal tube 4a having an elliptical cross section, and the entire surface or the peripheral surface of only the hand-held side is covered with a rubber-like elastic material. On the open end side of the handle 4, a synthetic resin lid plug as shown by 6 is inserted. The lid 6 forms a protruding seat 6a inserted into the metal tube 4a as shown in the broken part of FIG. 4, and the protruding seat 6a forms a support seat 6b as shown in FIG.

On the other hand, a level 7 forming the level apparatus 5 utilizes a straight tube type bubble tube, and is separated from the handle 4 at the hand side of the handle 4 and the protrusion of the lid plug 6 as shown in FIG. A groove 7a (FIG. 4) is formed and arranged on the handle 4 corresponding to the seat 6a. In the arrangement, the lower end edge 2a of the leveling plate 2 attached to the handle 4 is placed on a horizontal base, and the plaster is used for the adjustment so that the projection 6a of the lid 6 is stably supported. Then, the bubble of the level 7 is attached to the groove 7a and the protruding seat 6a so that the bubble is at the center as shown in FIG. When replacing the leveling plate, adjust the leveling plate 7 with the leveling plate mounting bolts shown in FIG.

FIG. 6 (a side view corresponding to FIG. 3) shows an example in which the present invention is applied to a leveler 1 having a handle 4 formed of wood. That is, a window hole 7b is formed on the upper surface on the hand side of the wooden handle 4b, and an insertion hole (not shown) for the level 7 is provided on the side surface of the wooden handle 4b so as to correspond to the window hole 7b. 7 is arranged. In the arrangement, the level 7 is adjusted and fixed as described in the previous section, and the insertion hole is closed on both sides or one side with a filler such as gypsum to fix the level 7.

In these embodiments, the level device is arranged inside the handle. However, the level device may be provided at an appropriate position on the handle 4 because it is easy to see and adjust. FIGS. 7 (a side view corresponding to FIG. 5) and FIG. 8 (a side view corresponding to FIG. 4) show a configuration in which the level device 5 is attached to the upper side of the handle 4. That is, the level 7 is inserted into the support seat 8 formed of a synthetic resin or the like with a bottomed hole formed therein, and a screw groove is formed on the insertion side, and the level 7 is fixed with the stopper lid 8b (FIG. 8). To support. On the other hand, a lower central portion of the support seat 8 forms a support portion 8a, and the support portion 8a is screwed to the mounting seat. FIG. 7 shows a state in which the mounting seat 9 is fastened with a fastening screw 10 between projecting walls formed on the top of the mounting seat 9 laid over the handle 4, and FIG. Fasten to the protruding wall of the seat plate 11 with the fastening screw 10.

The leveling device 5 fastened by the fastening screw 10 is easy to adjust when the lower edge of the leveling plate 2 is worn out or when the leveling plate is replaced. Although not shown in the drawings, the mounting seat 9 and the mounting seat plate 11 are respectively formed with protruding walls on fastening bands that surround the outer periphery of the handle 4 and can be tightened at a free position, and are fastened with fastening screws. You may comprise.
