Description

TECHNICAL FIELD

[0001] The application relates to the technical field of overhead platform construction, in particular to an outer wall trolley for an overhead platform. BACKGROUND

[0002] At present, overhead platforms are usually used in the structures of railway platforms such as high-speed railways. Due to the structural characteristics of the overhead platforms, an overhead passage formed by walls or columns is usually arranged at the bottom of the overhead platform, and the overhead passage has the characteristics of long space and low height.

[0003] The research direction of the overhead platform construction is mainly to use a fabricated steel structure frame or a fabricated prefabricated frame to match a prefabricated plate. For cast-in-situ concrete construction, the traditional full-frame matching wood formwork construction is still used, and there are many limitations. In particular, when the outer wall of the overhead platform is constructed, wall formwork, inside corner formwork and outside corner formwork need to be erected, and the structure is relatively complex. A large amount of complex formwork assembly and disassembly operations need to be carried out in the formwork supporting process, which leads to great construction difficulty. Since the formwork assembly operation is mainly completed by manual work, it depends on the experience of construction personnel, and there is a problem of great quality control difficulty.

[0004] Therefore, it is necessary to provide an outer wall trolley for an overhead platform to reduce the construction difficulty and the quality control difficulty. CONTENT OF THE INVENTION

[0036] Embodiment

[0037] Reference Figure 1 As shown, the embodiment provides an outer wall trolley of an elevated platform, which comprises a trolley support 1, an outer wall formwork mechanism 2, a male corner formwork 3 and a female corner formwork 4.

[0038] The outer wall formwork mechanism 2 comprises a side formwork 21 and a retraction mechanism connected between the trolley support 1 and the side formwork 21 for driving the side formwork 21 to retract and support the formwork. The side formwork 21 is used to support the outer side 7 of the outer wall.

[0039] The male corner formwork 3 is connected with the elevator 35; referring to Figure 5 As shown, the male corner formwork 3 comprises a first formwork 31, a second formwork 32 and a third oil cylinder 36, the first formwork 31 is hinged with the second formwork 32; the first formwork 31 is supported on the side of the male corner, and the second formwork 32 is supported on the bottom of the male corner; the second formwork 32 is provided with an auxiliary support, the auxiliary support comprises a first rod body 33 extending in the horizontal direction, one end of the third oil cylinder 36 is hinged with the first formwork 31, and the other end is hinged with the first rod body 33; the elevator 35 is connected on the trolley support 1, and is used to drive the male corner formwork 3 to move in the vertical direction. The male corner formwork 3 is divided into the first formwork 31 and the second formwork 32 which are hinged with each other, in the process of closing the male corner formwork 3, the first formwork 31 is turned over by the third oil cylinder 36 to be demoulded, and then the male corner formwork 3 is driven by the elevator 35 to move downward to demould the second formwork 32, which can reduce the friction between the formwork and the concrete of the male corner structure in the demoulding process, so as to avoid the damage to the male corner structure caused by demoulding as much as possible.

[0040] The female corner formwork 4 is hinged on the edge of the male corner formwork 3, and the second oil cylinder 41 is arranged between the female corner formwork 4 and the male corner formwork 3. Before the male corner formwork 3 is driven by the elevator 35 to move downward, the female corner formwork 4 is turned over by the second oil cylinder 41, so as to reduce the damage to the female corner structure in the demoulding process.

[0041] The outer wall trolley of the overhead platform provided by the embodiment can adapt to the complex structure of the outer wall of the overhead platform, improve the degree of automation, and automatically close and support the formwork, so as to reduce the construction difficulty of the complex outer wall, get rid of the dependence on the experience of workers, better control the construction quality, and in the process of closing the formwork, the first formwork 31 of the male corner formwork 3 and the female corner formwork 4 are turned over respectively, so as to avoid the damage to the female corner and the male corner position as much as possible.

[0042] Specifically, the retracting mechanism comprises a plurality of connecting rods 22 and a first oil cylinder 23; one end of each connecting rod 22 is hinged to the trolley support 1, and the other end is hinged to the side formwork 21; the plurality of connecting rods 22 are arranged along the vertical direction of the overhead platform and are parallel to each other; one end of the first oil cylinder 23 is hinged to the trolley support 1, and the other end is hinged to the side formwork 21; the first oil cylinder 23 is arranged obliquely, and the hinged point of the first oil cylinder 23 to the trolley support 1 is higher than the hinged point of the first oil cylinder 23 to the side formwork 21. During the processes of form supporting and form stripping, the plurality of connecting rods 22 remain parallel and keep the side formwork 21 always parallel to the side of the trolley support 1, and the connecting rods 22 do not need to be disassembled before and after the form stripping and form supporting, thereby reducing the construction amount of form stripping and form supporting and improving the construction efficiency. The oblique arrangement of the first oil cylinder 23 enables the side formwork 21 to move obliquely upward in the direction of approaching the trolley support 1 during form stripping, so that the side formwork 21 can be separated from the bottom surface and the side surface, and the requirement for the form stripping space is reduced.

[0043] Specifically, the first rod body 33 is connected with a second rod body 34 extending in the vertical direction, and one end of the second oil cylinder 41 is hinged to the second rod body 34, and the other end is hinged to the internal corner formwork 4.

[0044] Specifically, the elevator 35 is connected between the second formwork 32 and the trolley support 1, and the second formwork 32 is vertically moved by the elevator 35, thereby driving the internal corner formwork 4 and the external corner formwork 3 to move integrally.

[0045] Specifically, during form supporting, the side of the internal corner formwork 4 away from the external corner formwork 3 abuts against the top of the side formwork 21; as shown in Figure 4 , the side of the internal corner formwork 4 away from the external corner formwork 3 is a beveled opening 42; and the top of the side formwork 21 is a flat opening 24. Since the movement track of the side formwork 21 during form stripping is oblique upward movement in the direction of approaching the trolley support 1, the beveled opening 42 of the internal corner formwork 4 away from the external corner formwork 3 can avoid interference with the form stripping of the side formwork 21, and ensure smooth movement of the side formwork 21.

[0046] Specifically, as shown in Figure 4 , the inner side of the side formwork 21 is provided with a connecting plate 25, the connecting plate 25 is provided with a abutting bolt 26, and when the beveled opening 42 of the internal corner formwork 4 abuts against the flat opening 24 of the side formwork 21, the abutting bolt 26 abuts against the beveled opening 42 of the internal corner formwork 4. Since the position of the beveled opening 42 of the internal corner formwork 4 is relatively weak, the abutting bolt 26 is used to support the beveled opening 42 part, thereby improving the stability and reliability between the internal corner formwork 4 and the side formwork 21.

[0047] Specifically, the trolley support 1 is provided with a walking system 5 at the bottom, which cooperates with a track 6 arranged on the concrete raft. The trolley support 1 is moved by the walking system 5, so that the external wall trolley can be moved to different construction sections, improving the degree of automation. The walking system 5 in the embodiment can be selected from a chain type, a roller type or other forms of walking structure.

[0048] Specifically, the trolley support 1 is a door-shaped frame structure, which facilitates personnel movement and operation.

[0049] The demolding process is as follows: first, the side mold plate 21 is moved obliquely upward by the first oil cylinder 23 and the connecting rods 22 kept parallel, so as to be demolded; then the female corner mold plate 4 and the first mold plate 31 are flipped and demolded by the second oil cylinder 41 and the third oil cylinder 36 respectively; finally, the second mold plate 32 is lowered by the elevator 35, so as to drive the female corner mold plate 4 and the male corner mold plate 3 to move downward, providing space for the horizontal movement of the external wall trolley and avoiding interference.

[0050] When the demolding is completed, the external wall trolley is moved along the track 6 by the walking system 5, so as to be moved to the next construction section.

[0051] The formwork process is opposite to the above-described demolding process, which is not described in detail in the embodiment.

[0052] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0053] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are all within the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
