Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a bridge deck paving concrete vibrating device and a construction method thereof. Background Art

[0002] During the construction of bridge deck concrete pavement, the control of the thickness, slope and flatness of the bridge deck pavement layer is the key point of quality control, which directly affects the strength and drainage performance of the bridge deck surface layer. Traditional bridge deck pavement uses three rollers for bridge deck pavement construction. Due to the heavy weight of the three rollers themselves, there are safety risks and hidden dangers in high-pressure air conditioning. In addition, concrete or steel tracks need to be set before the construction of the bridge deck pavement layer. The process is relatively cumbersome and increases the input of labor. Especially for curved bridge sections, the three rollers cannot be laid and need to be operated manually. It is difficult to ensure the overall quality of the pavement on site.

[0031] Reference Figure 1 As shown, the present invention provides a bridge deck paving concrete vibrating device, comprising: a bracket 1, a slide rail 2, a veneer beam 3, a vibrator 4 and a traction mechanism.

[0032] In this embodiment, the number of brackets 1 is at least two rows. Each row of brackets has a plurality of brackets.

[0035] The veneer beam 3 is movably placed on the top surface of the slide rail 2 on at least two rows of brackets 1. The veneer beam can slide on the slide rail. In this embodiment, the slide rail can not only support the veneer beam, but also be used as a thickness indicator mark to indicate the concrete pavement layer.

[0036] There are multiple vibrators 4 . Multiple vibrators 4 are installed on the facing beam 3 .

[0037] In this embodiment, the vibrator 4 is a high-frequency attached vibrator 4 .

[0038] As a preferred embodiment, the number of the vibrators 4 is at least three, and the multiple vibrators 4 are arranged at intervals along the length direction of the veneer beam 3 .

[0039] In this embodiment, three vibrators are respectively installed at the left and right ends and the middle of the top of the veneer beam.

[0040] The traction mechanism is installed on the bridge deck and is used to drive the veneer beam 3 to slide along the length direction of the slide rail 2.

[0041] Specifically, the traction mechanism includes: a winch and a cable 51 .

[0042] The winch is installed on the bridge deck. There are at least two cables 51. One end of the cable 51 is connected to the end of the veneer beam 3. One end of the two cables is connected to the two ends of the veneer beam respectively. The other ends of the two cables 51 are wound on the drum of the winch.

[0043] In this embodiment, holes are drilled at both ends of the veneer beam or closed pull rings are welded with steel bars, and the holes or rings are connected to the cables to connect to the drum of the traction mechanism.

[0044] The present invention provides a construction method of a bridge deck paving concrete vibrating device, comprising the following steps:

[0045] S1. At least two rows of brackets 1 are fixedly installed on the base layer 6 of the bridge deck.

[0046] S2. Install the slide rails 2 on each row of brackets 1 so that the elevation of the top surface of the slide rails 2 is adapted to the design elevation of the top surface of the concrete pavement layer 7 of the bridge deck.

[0047] S3, pouring concrete on the base layer 6 of the bridge deck so that the liquid level of the concrete is adapted to the elevation of the top surface of the slide rail 2.

[0048] S4, movably placing the veneer beam 3 on the top surface of the slide rail 2 on at least two rows of brackets 1;

[0049] S5. Turn on multiple vibrators 4.

[0050] S6. The traction mechanism drives the trial veneer beam 3 to slide along the length direction of the slide rail 2 so that the concrete can be evenly and flatly spread on the base layer 6.

[0051] The bridge deck paving concrete vibrating device of the present invention utilizes the deadweight of the veneer beam and the vibration force transmitted by the vibrator to evenly and evenly spread the concrete on the bridge deck. The veneer beam is supported by mounting brackets and slide rails on the base layer of the bridge deck, so that the veneer beam can slide along the concrete liquid surface of the concrete paving layer of the bridge deck, thereby ensuring the construction quality of the bridge deck paving layer. The bridge deck paving concrete vibrating device of the present invention can not only ensure the uniform spreading of concrete but also ensure the thickness, slope and flatness of the paving layer, and can also reduce the input of labor, save construction period, ensure construction quality, avoid high-pressure and low-pressure operation, and reduce the safety risks and hidden dangers of construction.

[0052] The bridge deck paving concrete vibrating device of the present invention is easy to operate, safe and reliable, and can adjust the length and range of the veneer beam according to the actual situation on site, and can also be operated without obstacles in the curved section. The bridge deck paving concrete vibrating device of the present invention has high turnover efficiency, and is simple and quick to operate and install.

[0053] Compared with the traditional three-roller paver, the bridge deck paving concrete leveling device of the present invention effectively solves the problem that the curved section of the bridge deck paving cannot be constructed. There is no need to set up concrete or steel rails as the load-bearing fulcrum and channel of the device. Only a simple supporting sliding rail needs to be set up. The operation is simple, safe and practical.

[0054] Before pouring concrete on the concrete pavement layer, the bridge deck pavement layer is made of φ16 round steel to make a bracket and welded and fixed along the bridge according to the elevation points to form a slide rail. When pouring the pavement concrete, the veneer beam is placed on the slide rail, and the traction mechanism slowly moves the veneer beam along the bridge through the cable, and the concrete is evenly and flatly spread on the bridge deck by using the deadweight of the veneer beam and the vibration force transmitted by the high-frequency attached vibrator.

[0055] The bridge deck paving concrete vibrating device of the present invention is suitable for viaduct bridge deck paving engineering, saves time and labor, has low cost, flexible setting, strong operability, and construction safety, quality, and construction period are all guaranteed.

[0056] Compared with the traditional three-roller construction method, the bridge deck paving concrete leveling device of the present invention can greatly shorten the construction period and reduce the cost. If three rollers are used for bridge deck paving construction, it is necessary to cast the concrete track elevation belt or weld the steel track in sections before pouring the paving layer. The installation process is cumbersome and the weight of the three rollers is about 2 to 3 tons, which is not easy to lift. The market price of a three-roller is about 35,000 yuan. If each work area purchases one, the total cost of three three-rollers is about 105,000 yuan. The casting of the concrete track elevation belt requires templates and labor costs totaling about 80,000 yuan (steel track welding requires channel steel materials and labor costs totaling about 100,000 yuan).

[0057] The cost of the bridge deck paving concrete vibrating device of the present invention includes one 6-8m veneer beam (steel pipe, market price is about 700 yuan), three high-frequency attached vibrators (one market price is about 320 yuan), and the total cost of equipping three devices on site is about 4,980 yuan.

[0058] In summary, after cost analysis and comparison of the two devices, the bridge deck paving concrete vibrating device of the present invention can save costs of approximately RMB 180,020 to 200,020.

[0059] The bridge deck paving concrete vibrating device of the present invention can effectively save labor and material costs, shorten the construction period, effectively control the quality of bridge deck paving concrete, promote resource conservation, and has no pollution or dust to the environment during implementation, saving materials and being environmentally friendly.

[0060] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
