Description

Technical Field

[0001] The invention relates to the technical field of open tunnel arch construction, and in particular to a trolley system concrete pouring and vibrating device. Background Art

[0002] The construction of Myeongdong Tunnel is a typical reinforced concrete structure construction. In the process of reinforced concrete structure construction, the trolley system is generally rarely used in the common cycle construction process such as steel bar binding → formwork support → concrete pouring. However, unlike the ordinary reinforced concrete structure construction process, the construction of the arch structure of Myeongdong Tunnel is a typical linear project, with a large amount of steel bar engineering, formwork engineering and concrete engineering work, and the traditional formwork installation and disassembly process is cumbersome and time-consuming. Therefore, the formwork trolley is often used in the construction of the arch structure of Myeongdong Tunnel. The formwork trolley can realize rapid formwork movement, greatly improving the construction efficiency, while also ensuring the consistency and accuracy of the structure during the construction process, reducing the complexity of on-site construction, and reducing the risk of quality problems during construction.

[0003] Conventional concrete pouring technology, such as "one-hole pouring to the bottom", can easily lead to concrete segregation, insufficient vibration and the formation of cavities inside the concrete, and the construction efficiency and quality of the arch structure concrete pouring cannot be guaranteed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art and to propose a trolley system concrete pouring and vibrating device, thereby solving the problems existing in the prior art.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A trolley system concrete pouring and vibrating device comprises an inner mold trolley and an outer mold trolley, wherein the inner mold trolley is provided with an inner mold that arches upward, and the outer mold trolley comprises four columns, the upper sides of the four columns are fixedly connected to a cross beam, winches are arranged at both ends of the cross beam, the cables of the winches are fixedly connected to an upper mold, the upper mold is hingedly connected to a plurality of middle molds in sequence, the lower end of the middle mold is hingedly connected to a lower mold, and two columns located on the same side are respectively hingedly connected to a hydraulic rod, and the hydraulic rod is hingedly connected to the lower mold;

[0007] Inserted vibrators are arranged at intervals of the inner formwork, and the upper formwork, the middle formwork and the lower formwork are respectively fixedly connected to the flat plate vibrators.

[0008] Preferably, the columns and beams are fixedly connected to arc-shaped guide rails on their sides, the arc-shaped guide rails are slidably connected to sliding seats, the sliding seats are fixedly connected to hydraulic telescopic push rods, and the telescopic ends of the hydraulic telescopic push rods are rotatably connected to rollers.

[0009] Preferably, the upper side of the cross beam is fixedly connected to a support plate, a material distribution trolley is arranged on the upper side of the support plate, and both sides of the material distribution trolley are respectively fixedly connected to the casting pipes.

[0010] Preferably, the upper side of the support plate is fixedly connected to a groove-shaped track, and the wheels of the material distribution trolley are located in the groove-shaped track.

[0011] Preferably, the inner arc surfaces of the upper template, the middle template and the lower template are respectively fixedly connected with rubber strips.

[0012] Preferably, the rubber strip is of a hollow structure, a first buffer is arranged between the upper template and the middle template, and a second buffer is arranged between the middle template and the lower template, and the first buffer and the second buffer have the same structure;

[0013] The second buffer includes a round rod, a groove is arranged at the lower end of the outer side of the middle template, the round rod is fixedly connected in the groove, a pull rod is hingedly connected to the round rod, a cavity is arranged in the lower template, the pull rod extends into the cavity and a boss is arranged, and a buffer spring is fixedly connected between the boss and the inner wall of the cavity.

[0014] Preferably, the upper template and the middle template are fixedly connected with an inclined block at intervals, and an anti-skid groove is provided on the inclined surface of the inclined block, so that the roller can roll through the inclined block.

[0015] The advantages of the present invention are as follows: the concrete pouring and vibrating device of a trolley system provided by the present invention diverts concrete to the desired position for layered pouring through a material distribution trolley. During the concrete pouring process, a side-top arch attached vibrating system equidistantly arranged at the inner mold position of the inner mold trolley is used in combination with an inserted vibrator to complete the vibrating operation during the concrete pouring process of the arch structure. The use of a material distribution trolley can realize layered pouring of each window, reduce the labor intensity of workers, overcome the concrete segregation caused by "one-hole pouring to the bottom" pouring, and thus improve the construction efficiency and quality of the concrete pouring of the arch structure.

[0016] During layered pouring, the outer formwork of the outer formwork trolley is composed of an upper formwork, a middle formwork and a lower formwork, which are closed in sequence so that the layered pouring bin is open on the upper side, which is convenient for the flow of concrete and the control of pouring quality.

[0017] The present invention uses the rubber strip to seal and prevent collision. On the other hand, after being squeezed with the inner template, the rubber strip has space for up and down, inside and outside vibration. The inclined block is squeezed by the roller, so that the middle template is lifted upward. After the roller leaves the inclined block, the middle template drops due to its own weight. The arc contact of the rubber strip can ensure sealing and cooperate with the up and down vibration of the middle template, so that the concrete poured into the casting bin can be substantial and can be fully vibrated, thereby ensuring density.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] like Figure 1-3 As shown, a trolley system concrete pouring and vibrating device provided by the present invention comprises an inner mold trolley 1 and an outer mold trolley 2. The inner mold trolley 1 is provided with an inner mold plate 11 that arches upward. The outer mold trolley 2 comprises four columns 21. The upper sides of the four columns 21 are fixedly connected to a cross beam 22. A winch 23 is arranged at both ends of the cross beam 22. The cable of the winch 23 is fixedly connected to an upper mold plate 24. The upper mold plate 24 is hingedly connected to a plurality of middle mold plates 25 in turn. The lower end of the middle mold plate 25 is hingedly connected to a lower mold plate 26. The two columns 21 on the same side are connected to the lower mold plate 26. 1 are respectively hingedly connected to the hydraulic rod 27, and the hydraulic rod 27 is hingedly connected to the lower template 26. The hydraulic rod 27 is extended to make the lower template 26 close to the inner template 11, and the cavity between the lower template 26 and the inner template 11 is poured in layers. Compared with the existing closed cavity grouting, it is possible to directly pay attention to the pouring working conditions, which is convenient for quality control; after the side of the lower template 26 is poured in place, the winch 23 releases the cable, so that the middle template 25 is close to the inner template 11 to form a subsequent pouring bin, and the layered and pouring process is open, which is convenient for vibration and compaction;

[0023] Insertion vibrators 12 are arranged at intervals on the inner template 11, and the upper template 24, the middle template 25 and the lower template 26 are respectively fixedly connected to the flat plate vibrators 28. The insertion vibrators 12 and the flat plate vibrators 28 are both conventional vibration devices.

[0024] The upper side of the cross beam 22 is fixedly connected to the support plate 4, and a material distribution trolley 41 is arranged on the upper side of the support plate 4. Concrete from the concrete pump truck falls into the material distribution trolley 41. Casting pipes 42 are fixedly connected to both sides of the material distribution trolley 41 respectively. Concrete is dispersedly poured through the material distribution trolley 41. The upper side of the support plate 4 is fixedly connected to a groove track 43, and the wheels of the material distribution trolley 41 are located in the groove track 43.

[0025] During the construction of the arch of the Myeongdong Tunnel, the inner formwork trolley 1 arrives at the construction section and forms a whole with the outer formwork trolley 2. The end formwork 10 seals the end face, ear plates 20 are set on the inner and outer formworks, and the pressure rods 30 are inserted and tightened to finally fix them into a whole. The inner and outer formwork trolleys 1 and 2 are used as the steel bar skeleton of the arch structure, and concrete is poured between the inner and outer formwork trolleys 1 and 2.

[0026] The present invention uses a material distribution trolley 41 to divert concrete to the desired positions for layered pouring. During the concrete pouring process, a side-top arch attached vibrating system equidistantly arranged at the inner mold plate 11 position of the inner mold trolley 1 is used in conjunction with an inserted vibrator 12 to complete the vibrating operation during the concrete pouring process of the arch structure. The material distribution trolley 41 can be used to realize layered pouring of each window, reduce the labor intensity of workers, overcome the concrete segregation caused by "one-hole pouring to the bottom" pouring, and thus improve the construction efficiency and quality of the arch structure concrete pouring.

[0027] During layered pouring, the outer formwork of the outer formwork trolley 2 is composed of an upper formwork 24, a middle formwork 25 and a lower formwork 26, which are closed in sequence so that the layered pouring bin is open on the upper side, which is convenient for the flow of concrete and the control of pouring quality.

[0028] As an embodiment of the present invention, the side of the column 21 and the beam 22 is fixedly connected to the arc guide rail 3, the arc guide rail 3 is slidably connected to the slide seat 31, the slide seat 31 is driven to slide on the arc guide rail 3 by the existing driving mechanism, the slide seat 31 is fixedly connected to the hydraulic telescopic push rod 32, and the telescopic end of the hydraulic telescopic push rod 32 is rotatably connected to the roller 33, such as Figure 1 As shown, the upper template 24 and the middle template 25 are spread outward, and when the slide 31 moves along the arc guide rail 3, the roller 33 pushes the middle template 25 and the upper template 24 toward the inner template 11 in sequence. During the process, pouring is carried out in layers. After the template is completely enclosed, additional pouring is carried out in the top reserved hole in a conventional manner to avoid the situation where the template is completely closed and the internal pouring situation is unclear, affecting the pouring quality.

[0029] As an embodiment of the present invention, the inner arc surfaces of the upper template 24, the middle template 25 and the lower template 26 are respectively fixedly connected to the rubber strip 5, the rubber strip 5 is a hollow structure, a first buffer is arranged between the upper template 24 and the middle template 25, and a second buffer 6 is respectively arranged between the middle template 25 and the lower template 26, and the first buffer and the second buffer 6 have the same structure;

[0030] The second buffer 6 includes a round rod 61, a groove 62 is set at the lower end of the outer side of the middle template 25, the round rod 61 is fixedly connected in the groove 62, a pull rod 63 is hingedly connected to the round rod 61, a cavity 64 is set in the lower template 26, the pull rod 63 extends into the cavity 64 and a boss 65 is set, and a buffer spring 66 is fixedly connected between the boss 65 and the inner wall of the cavity 64. Through this structure, the middle template 25 has the advantages of moving up and down relative to the lower template 26 and vibrating as a whole by hinge.

[0031] Furthermore, the upper template 24 and the middle template 25 are fixedly connected to an inclined block 67 at intervals, and an anti-skid groove is provided on the inclined surface of the inclined block 67, so that the roller 33 can roll through the inclined block 67.

[0032] On the one hand, the rubber strip 5 is fitted for sealing and collision prevention. On the other hand, after being squeezed with the inner template 11, the rubber strip 5 has space for up and down, inside and outside vibration. The roller 33 squeezes the inclined block 67, so that the middle template 25 is lifted upward. After the roller 33 leaves the inclined block 67, the middle template 25 drops due to its own weight. The arc contact of the rubber strip 5 can ensure sealing and cooperate with the up and down vibration of the middle template 25, so that the concrete poured into the casting bin can be substantial and can be fully vibrated, thereby ensuring density.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
