Description

Technical Field

[0001] The invention relates to the technical field of slope concrete construction equipment, specifically a two-way slope concrete surface layer slope control device. Background Technology

[0002] In construction projects, when constructing large-area concrete surfaces such as parking lots, plazas, and roofs, it is often necessary to set up bi-directional slopes to achieve drainage. The bi-directional slopes, through the designed slope, form an invisible "drainage net" that allows rainwater or other liquids to flow quickly and orderly to the pre-set drainage outlets (such as floor drains, rainwater inlets, and drainage ditches), avoiding disorderly overflow or accumulation on the surface.

[0003] Traditional slope control methods typically rely on manual operation, involving frequent measurements using instruments such as levels and leveling rods. This process is complex and inefficient. During construction, workers adjust formwork or leveling devices based on experience, making it difficult to ensure the uniformity and accuracy of the surface slope. This approach can easily lead to problems such as localized water accumulation and excessive slope deviations, affecting the normal use of the site and potentially resulting in wasted materials and labor costs due to rework.

[0004] Therefore, those skilled in the art have provided a bidirectional slope control device for concrete surface layers to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide a slope control device for bidirectional sloping concrete surface layers to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the invention provides the following technical solution: A bidirectional sloping concrete surface slope control device includes a steel formwork, a support frame, and a sloping mechanism. The upper side of the steel formwork is fixedly connected to a guide rail block. The lower sides of the two sets of support frames are respectively rotatably connected to two sets of support rollers. The sloping mechanism is fixedly connected to the side of the two sets of support frames that are close to each other. The lower sides of the two sets of sloping mechanisms are respectively fixedly connected to a first scraper plate and a second scraper plate. The sloping mechanism is used to adjust the angle of the first scraper plate and the second scraper plate.

[0007] As a further aspect of the invention: the slope-clearing mechanism includes a vibration unit, which is used to drive the first and second mud-scraping plates to vibrate.

[0008] As a further aspect of the invention: the slope-releasing mechanism further includes a slope-releasing angle adjustment unit, which is used to adjust the angles of the first mud-scraping plate and the second mud-scraping plate.

[0009] As a further embodiment of the invention: the vibration unit includes a vibration beam keel, a vibration rod and a vibration motor, and the two sets of support frames are rotatably connected to the vibration beam keel on the side close to each other. The inner sides of the two sets of vibration beam keels are respectively fixedly connected to the vibration rod, and one end of the two sets of vibration rods is fixedly connected to the vibration motor.

[0010] As a further embodiment of the invention: the slope angle adjustment unit includes a slope angle controller, a scale plate, a wire rope tightening device, a wire rope tightening rod, a wire rope guide plate, and a wire rope. One side of each of the two sets of support frames is rotatably connected to the slope angle controller. One end of each of the two sets of slope angle controllers is fixedly connected to a set of vibrating beam joists. A scale plate is fixedly connected to the side of each of the two sets of support frames near the slope angle controller. A wire rope tightening rod is rotatably connected to the inner side of each of the two sets of support frames. A wire rope tightening device is provided on both sides of each of the two sets of wire rope tightening rods. A wire rope is provided on the outer side of each of the two sets of wire rope tightening rods. The other end of each of the two sets of wire ropes is fixedly connected to a set of vibrating beam joists. One side of each of the two sets of support frames is fixedly connected to a set of wire rope guide plates. Each of the two sets of wire ropes slides through and approaches a set of wire rope guide plates.

[0011] As a further aspect of the invention, an adjustment groove is provided on the side of the first and second mud-scraping plates that are close to each other.

[0012] As a further aspect of the invention, movable connecting bolts pass through the inner sides of the two sets of adjusting grooves, and one end of each bolt passes through a threaded connecting nut.

[0013] As a further aspect of the invention, the two sets of vibratory beam keels and vibratory rods are made of metal.

[0014] Compared with existing technologies, the beneficial effects of the invention are: This invention utilizes a method of single-stage vibration molding to achieve a bi-directional slope in concrete road surfaces. Compared to traditional vibratory beam construction methods, which only level the road surface and cannot simultaneously achieve bi-directional slope, thus failing to meet design standards, this method is cumbersome and inefficient. Furthermore, traditional methods typically require repeated measurements and manual vibration at fixed points to ensure slope accuracy. In contrast, the device of this invention only requires adjusting the angles of the bi-directional slope devices on both sides and tightening the steel cables at the start of vibration, easily setting up the bi-directional slope and significantly saving construction time and labor costs, thereby improving construction efficiency.

[0021] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a bidirectional sloping concrete surface slope control device, including a steel template 1, a support frame 2, and a sloping mechanism 3. The upper side of the steel template 1 is fixedly connected to a guide rail block 11. The lower sides of the two sets of support frames 2 are respectively rotatably connected to two sets of support rollers 21. The sloping mechanism 3 is fixedly connected to the side of the two sets of support frames 2 that are close to each other. The lower sides of the two sets of sloping mechanisms 3 are respectively fixedly connected to a first mud-scraping plate 41 and a second mud-scraping plate 42. The sloping mechanism 3 is used to adjust the angle of the first mud-scraping plate 41 and the second mud-scraping plate 42.

[0023] In this embodiment, when a bidirectional slope is required on the concrete surface, steel templates 1 are installed on both sides of the concrete surface. The support frame 2 on one side of the steel template 1 is guided and rolled on the guide rail block 11 by two sets of support rollers 21 at the lower end. The support rollers 21 enable the slope mechanism 3 to move smoothly on the steel templates 1 on both sides, preventing the device from derailing. Then, after adjusting the angle of the first mud scraping plate 41 and the second mud scraping plate 42 by the slope mechanism 3, the first mud scraping plate 41 and the second mud scraping plate 42 form an inverted "V" shape with the cast-in-place concrete surface. Then, under the action of the weight of the equipment itself, the first mud scraping plate 41 and the second mud scraping plate 42 move slowly, so that the concrete surface layer passed by the first mud scraping plate 41 and the second mud scraping plate 42 presents the originally designed bidirectional slope form.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, optionally, the slope-clearing mechanism 3 includes a vibration unit, which is used to drive the first mud-scraping plate 41 and the second mud-scraping plate 42 to vibrate.

[0025] In this embodiment, the vibration unit in the slope mechanism 3 is used to drive the first mud scraping plate 41 and the second mud scraping plate 42 to vibrate, so that the concrete can fill the corners and gaps in the template more evenly.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, optionally, the slope mechanism 3 further includes a slope angle adjustment unit, which is used to adjust the angle of the first mud scraper plate 41 and the second mud scraper plate 42.

[0027] In this embodiment, the vibration unit drives the first mud-scraping plate 41 and the second mud-scraping plate 42 to make the concrete surface present the originally designed bi-directional slope form. At the same time, the bi-directional slope form of the concrete surface evenly fills all corners and gaps in the template, expelling the air mixed in and making the concrete texture denser. The slope angle adjustment unit in the slope mechanism 3 is used to adjust the angle of the first mud-scraping plate 41 and the second mud-scraping plate 42.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, optionally, the vibration unit includes a vibration beam keel 31, a vibration rod 32, and a vibration motor 33. The two sets of support frames 2 are rotatably connected to the vibration beam keel 31 on their respective sides that are close to each other. The inner sides of the two sets of vibration beam keels 31 are respectively fixedly connected to the vibration rod 32, and one end of the two sets of vibration rods 32 is fixedly connected to the vibration motor 33.

[0029] In this embodiment, when the first mud scraper plate 41 and the second mud scraper plate 42 move, the vibration motor 33 is then turned on. The vibration motor 33 generates centrifugal force by rotating the internal eccentric block. When the vibration motor 33 starts running, the eccentric block rotates at high speed, continuously generating centrifugal force with periodically changing size and direction. This constitutes the original power of vibration. After the vibration is generated, it will spread rapidly along the structure of the vibrating beam keel 31 and the vibrating rod 32. Since concrete is a granular composite material, there are gaps and friction of different sizes inside. Under the high-frequency vibration of the vibrating beam keel 31 and the vibrating rod 32, the concrete particles overcome the friction between each other, and the originally relatively stable structure is broken. The concrete mixture begins to "liquefy", which means that it has better fluidity, can fill the corners and gaps in the template more evenly, and expel the air mixed in, making the concrete texture more compact, so that the concrete surface layer that passes through presents the originally designed two-way slope form.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, optionally, the slope angle adjustment unit includes a slope angle controller 34, a scale plate 35, a wire rope tightening device 36, a wire rope tightening rod 37, a wire rope guide plate 38, and a wire rope 39. The slope angle controller 34 is rotatably connected through one side of each of the two sets of support frames 2. One end of each of the two sets of slope angle controllers 34 is fixedly connected to a set of vibrating beam joists 31. The scale plate 35 is fixedly connected to one side of each of the two sets of support frames 2, respectively, close to one set of slope angle controllers 34. The inner sides of the two sets of support frames 2 are respectively rotatably connected to wire rope tensioning rods 37. Both sides of the two sets of wire rope tensioning rods 37 are provided with wire rope tensioning devices 36. The outer sides of the two sets of wire rope tensioning rods 37 are provided with wire ropes 39. The other ends of the two sets of wire ropes 39 are respectively fixedly connected to a set of vibrating beam keel 31. One side of the two sets of support frames 2 is respectively fixedly connected to a set of wire rope guide plates 38. The two sets of wire ropes 39 respectively pass through a set of wire rope guide plates 38 that slide close to each other.

[0031] In this embodiment, when the slope angle adjustment unit needs to be adjusted, the angle generated by the worker pressing down the control rod on the slope angle controller 34 is the angle at which the vibrating beam keel 31 is lifted. The slope angle of the device can be accurately determined by the slope angle controller 34. Although the slope angle has been determined after the slope angle controller 34 is set, the set slope angle may change due to the heavy weight of the vibrating beam keel 31 and the high-frequency vibration during operation. Therefore, a wire rope tightening device 36 is added to the upper part of the vibrating beam keel 31. The wire rope is used to lift the vibrating beam and play a secondary fixing role to prevent the set slope angle from changing due to vibration. The wire rope 39 is adjusted by the wire rope tightening device 36 and the wire rope tightening rod 37, and then the wire rope 39 is limited and fixed.

[0032] It should be noted that the slope angle controller 34 and the wire rope tensioning device 36 are existing technologies. The slope angle controller 34 and the wire rope tensioning device 36 have self-locking mechanisms (mainly ratchet and pawl) to reliably maintain this tension.

[0033] like Figure 1 and Figure 5 As shown, optionally, an adjustment groove 43 is provided on the side of the first mud scraper plate 41 and the second mud scraper plate 42 that are close to each other.

[0034] In this embodiment, both the first mud scraper plate 41 and the second mud scraper plate 42 have adjustment grooves 43 on their adjacent sides for placing bolts 44.

[0035] like Figure 1 and Figure 5 As shown, optionally, movable connecting bolts 44 pass through the inner sides of the two sets of adjusting grooves 43, and one end of the bolts 44 passes through threaded connecting nuts 45.

[0036] In this embodiment, a movable bolt 44 passes through the adjusting groove 43 between the first mud-scraping plate 41 and the second mud-scraping plate 42. A nut 45 is fixed to one end of the bolt 44. The bolt 44 and nut 45 only ensure that the first mud-scraping plate 41 and the second mud-scraping plate 42 do not separate, but do not tightly fix the first mud-scraping plate 41 and the second mud-scraping plate 42 together, thereby not affecting the control of the slope angle of the first mud-scraping plate 41 and the second mud-scraping plate 42. like Figure 1 As shown, optionally, the two sets of vibratory beam keel 31 and vibratory rod 32 are made of metal materials.

[0037] In this embodiment, both sets of vibratory beam joists 31 and vibratory rods 32 are made of metal materials. Metal materials have extremely high bending strength and torsional stiffness, ensuring that the vibratory beam joists 31 will not bend or twist under heavy self-weight and huge vibration load, maintaining the designed linear shape, thereby ensuring the flatness and slope accuracy of the concrete surface layer.

[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
