Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a corrugated road construction tool. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] At automotive proving grounds, corrugated pavement is primarily used for reliability and durability testing of vehicles. Traditional corrugated pavement construction involves laying precast concrete pavement slabs. However, during testing, these precast slabs are prone to surface step damage, resulting in poor pavement durability and a short service life.

[0004] To address the aforementioned issues, Chinese utility model patent application number CN201510639248.7 discloses a construction method for corrugated pavement in test tracks. This method improves pavement durability and service life by adding angle steel. However, this method requires a large number of angle steels, resulting in high costs. Furthermore, it requires individual operation during plastering and shaping, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings by providing a construction tool for corrugated road surfaces.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A tool for constructing corrugated road surfaces, comprising:

[0008] Multiple slabs, each extending along the width of the road surface, each slab having a side elevation, the side elevations of the slabs being spaced apart in a side-standing posture and extending along the length of the road surface, with material filling the space between adjacent slabs to form the road surface.

[0009] The scraper has multiple triangular plates on one side. The length of each triangular plate on the scraper corresponds to the width of the gap between two adjacent plates, and the end of the triangular plate away from the scraper is in contact with the side surface of the plate. The side of the corresponding triangular plate of the scraper is locked onto the top of the multiple plates by means of the groove formed between two adjacent triangular plates.

[0010] In use, the scraper surface, with a specified tilt angle, brings the triangular plate into contact with the material between two adjacent plates, smoothing and shaping the material between the two adjacent plates to form a washboard road surface.

[0011] Furthermore, the bottom of the plate has a horizontal plate, which is anchored to the foundation by bolts.

[0012] Furthermore, between two adjacent plates, the cross plate on the latter plate abuts against the bottom of the other plate.

[0013] Furthermore, the plate is made of angle steel.

[0014] Furthermore, the triangular plate is a right triangle, with the two right-angled sides located on the scraper and the side facade of the corresponding plate, respectively, and the right-angled side located on the side facade of the plate is in contact with the side facade of the plate.

[0015] Furthermore, a limiting plate is provided at the bottom of the scraper. The limiting plate is used to contact the top of the corresponding plate body when the scraper is working, in order to help limit the tilt angle of the scraper when it is working.

[0016] Furthermore, a pad is provided between the scraper and the limiting plate.

[0017] Furthermore, the material used to fill the space between two adjacent panels is gypsum mortar.

[0018] Furthermore, the scraper is provided with a handle.

[0019] The beneficial effects of this utility model are reflected in:

[0020] 1. Compared with the existing technology, the application uses half the amount of angle steel, which greatly reduces the material cost. In addition, the application uses a scraper in conjunction with the plate. The scraper uses multiple triangular plates at a specified angle to smooth and shape the material between multiple plates at the same time, which greatly improves the construction efficiency and is worth further promotion and application.

[0021] 2. This application utilizes the scraper and the plate body in conjunction. The plate body acts like a ruler to guide the scraper, while also limiting the height of the scraper. One end of the triangular plate is attached to the plate body, which is more conducive to the positioning and guidance of the triangular plate. With the cooperation of the scraper and the plate body, the material can be smoothed and shaped faster and better, and the operation accuracy is relatively high. Construction workers can also apply some force to the plate body through the scraper during operation, making the work relatively easier. Attached Figure Description

[0027] 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 a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figure 1-3 This utility model discloses a construction tool for corrugated road surfaces, comprising:

[0029] Multiple slabs 1, each slab 1 extending along the width of the road surface, each slab 1 having a side elevation, the side elevations of each slab 1 being distributed at intervals in a side-standing posture and extending along the length of the road surface, with material filling between two adjacent slabs 1 to form the road surface.

[0030] The scraper 2 has multiple triangular plates 21 on one side. The multiple triangular plates 21 are continuously distributed on one side of the scraper 2 to form a sawtooth shape. The length of each triangular plate 21 on the scraper 2 corresponds to the gap width between two adjacent plates 1, and the end of the triangular plate 21 away from the scraper 2 is in contact with the side surface of the plate 1. The side of the scraper 2 with the corresponding triangular plate 21 is locked on the top of the multiple plates 1 by means of the groove formed between two adjacent triangular plates 21.

[0031] In use, the scraper 2, with a specified tilt angle, brings the triangular plate 21 into contact with the material between the two adjacent plates 1, smoothing and shaping the material between the two adjacent plates 1 to form a washboard road surface.

[0032] Compared with the prior art, this utility model reduces the amount of angle steel used by half, greatly reducing material costs. By using a scraper 2 at a specified angle to simultaneously smooth and shape the material between multiple plates 1 with multiple triangular plates 21, the construction efficiency is greatly improved, and it has great promotional value.

[0033] Furthermore, this application utilizes the scraper 2 in conjunction with the plate body 1. The plate body 1 acts like a ruler to guide the scraper 2, while also limiting the height of the scraper 2. One end of the triangular plate 21 is attached to the plate body 1, which is more conducive to the positioning and guidance of the triangular plate 21. With the cooperation of the scraper 2 and the plate body 1, the material can be smoothed and shaped faster and better, and the accuracy of the operation is relatively high. Construction workers can also apply some force to the plate body 1 through the scraper 2 during operation, making the work relatively easier.

[0034] The reason why the scraper 2 moves at a specified tilt angle instead of vertically is that when the scraper 2 moves at an angle (less than 90°) to the direction of movement, excess material will be squeezed forward and downward. This results in a higher quality scraped surface and also carries excess material to areas where material is insufficient. If it moves vertically, it will not have this effect and will only scrape away excess material.

[0035] It should be noted that when panel 1 is a side panel, templates can be set on both sides of the road surface to fix each panel 1, so that each panel 1 always maintains a side posture. As for how to set the templates to fix each panel 1, it is obviously common knowledge in the art and will not be elaborated here.

[0036] It should be noted that during construction, slab 1 not only serves as a construction template, but also achieves "full life cycle support" through permanent fixation, significantly improving the overall integrity and service life of the road.

[0037] Preferably, the length of the plate 1 is equal to the width of the road surface (washboard road surface).

[0038] In one embodiment, the bottom of the plate 1 has a horizontal plate, which is anchored to the foundation by bolts. This design allows the plate 1 to be erected on the foundation without the need for a formwork, avoiding the dismantling and damage associated with traditional temporary formwork.

[0039] In one embodiment, between two adjacent plates 1, the bottom of the latter plate 1 abuts against the bottom of the other plate 1. With this design, after the first plate 1 is positioned, the other plates 1 do not need to be marked for positioning; they can simply be laid by abutting against the previous plate 1 in sequence, which speeds up the laying process.

[0040] Preferably, the plate 1 can be made of angle steel.

[0041] In one embodiment, the triangular plate 21 is a right triangle, with its two right-angled sides located on the side facades of the scraper 2 and the corresponding plate body 1, respectively, and the right-angled side located on the side facade of the plate body 1 is in contact with the side facade of the plate body 1. This design, on the one hand, by having the right-angled side in contact with the side facade of the plate body 1, facilitates control of the scraper 2's posture during movement (avoiding the scraper 2 from tilting left or right), and on the other hand, prevents excess material from crossing the triangular plate 21 when the scraper 2 moves, resulting in high work efficiency.

[0042] In one embodiment, a limiting plate 22 is provided at the bottom of the scraper 2. The limiting plate 22 is used to contact the top of each corresponding plate body 1 when the scraper 2 is working, in order to help limit the tilt angle of the scraper 2 when it is working.

[0043] In practice, scraper 2, with triangular plate 21, contacts the material at a specified tilt angle. At this time, limiting plate 22 falls on top of plate 1 and contacts plate 1. When working, the worker only needs to move scraper 2 in a straight line. With limiting plate 22 in contact with plate 1, it can help manually control the tilt angle of scraper 2 during operation. As a result, the final product has higher precision. Experiments have shown that the finished road surface has achieved industrial-grade precision (height difference control ≤ ±1mm) and edge integrity rate > 95%, far exceeding industry standards. At the same time, it reduces the rework rate (from 30% to < 5%), providing a replicable gold standard for special road surfaces (such as corrugated road and Belgian road).

[0044] In one embodiment, a pad 23 is provided between the scraper 2 and the limiting plate 22. This design can better transmit the force on the scraper 2 to the limiting plate 22 through the pad 23, and prevent the angle between the scraper 2 and the limiting plate 22 from changing.

[0045] In one embodiment, the material filling the space between two adjacent plates 1 is gypsum mortar.

[0046] In practice, gypsum mortar is used not only because of its short curing cycle, but also because it has better adhesion to scraper 2 and smaller deformation due to thermal expansion and contraction, making it more suitable for the structure of this application. If cement mortar is used for filling, expansion joints need to be made separately. However, if angle steel is used to make the corrugated road, it is difficult to cut expansion joints because the bottoms of the angle steel abut against each other (this is for quick laying of angle steel without the need for marking and positioning). If the distance between the angle steel is increased, additional marking and positioning are required, which affects the construction progress. Therefore, only the gypsum mortar + angle steel production scheme is the fastest construction efficiency while ensuring quality and quantity.

[0047] In one embodiment, the scraper 2 is provided with a handle 24 for easy operation by workers.

[0048] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0049] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0050] Additionally, "multiple" refers to two or more.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
