Description

A large channel construction mobile formwork

technical field

The utility model relates to the technical field of building construction supports, in particular to a large channel construction mobile formwork.

Background technique

As an integral part of urban expressways, underground passages are increasingly used in urban planning and development. The cross-sectional shapes of underground passages are usually rectangular, arched, circular and elliptical. At present, the common roof construction method of rectangular cross-section long passages has been applied relatively maturely, but due to the influence of time construction effect, the most used one is still Full house bracket method. This construction method is to set up scaffolding for the roof of each section of the channel. When the roof of the next channel is to be constructed, the workers need to remove the brackets used in the channel and re-build the brackets in the next channel. This process not only involves a lot of repetitive work, but also interferes with each other in the erection process of adjacent sections of support, and it is necessary to prepare at least the support materials required for the construction of the roof of the two-segment channel. Therefore, the traditional full house support method has disadvantages such as low construction efficiency, long period, large interference, and labor and material waste.

Detailed ways

The utility model will be described clearly and completely below in conjunction with accompanying drawing and embodiment:

As shown in Figures 1 to 2, a large channel construction mobile formwork according to the utility model includes a full hall support 1 formed by a vertical pole 3, a top support, a bottom support, a sweeping pole 4 and scissors. Since these materials and erection structures are relatively mature processes in the prior art, they will not be described in detail here; both sides of the full hall support 1 in the horizontal direction extend inward for a distance and are provided with support rods 2, preferably on each side. Extend inward for a distance of 1.8 meters for setting. Multiple support rods 2 are set along the length direction of the full hall support 1, and the support rods 2 are fixedly connected with the vertical rod 3 and the sweeping rod 4 on the full hall support 1. The bottom of each support rod 2 The end is provided with a moving roller 5, and the height of the moving roller 5 is adjustable to the support rod 2, so that by adjusting the height of the moving roller 5, the conversion of the supporting point is carried out, thereby satisfying the support of the full hall support 1 during moving and fixing construction. ; The moving track 6 is arranged along the moving direction of the mandrel bracket 1 below the moving roller 5, so that the moving roller 5 can walk stably and orderly along the moving track 6; the end of the mandrel support 1 is provided with a power traction device, which can pull the whole support to move , the traction device can use the oil cylinder to stretch and move forward, and can also use the method of setting up the chain on both sides of the full house support 1 to realize the movement of the full house support 1 by pulling the reverse chain, because these are the working principles of the prior art. It is well known to those skilled in the art, so details will not be repeated here.

The bottom plate 7 below the bottom bracket is provided with a pull rod 8, which is detachably connected to the vertical rod 3 above it; the setting of the pull rod 8 assists the screw rod 9 on the bottom bracket to enhance the support strength of the entire floor support 1 on the one hand. On the other hand, when it is necessary to move the full hall bracket 1, by moving up the pull rod 8 and the fixed position of the vertical rod 3 above it, it can drive the base plate 7 to move synchronously, so that the base plate 7 is separated from the ground. The screw mandrel 9 is in sliding contact with the vertical rod 3 above, which can prevent the base plate 7 from contacting the ground and affecting the overall movement of the floor support 1 due to the decline of the bottom support due to gravity.

Further, more than one set of pull rods 8 is provided. In this embodiment, one set is set, and two pull rods 8 are arranged symmetrically. The top end of each pull rod 8 is hinged on the mounting ring 10, and the mounting ring 10 is threaded on the lock. The tightening screw 11 is detachably arranged on the outside of the vertical rod 3 . Also be provided with chute 12 on the base plate 7, slide block 13 is arranged in the chute 12, pull bar 8 is hinged on the slide block 13, slides in slide block 13 in chute 12, can carry out the stress fulcrum of pull bar 8 Adjust to meet different usage situations; improve the practicability of the utility model. When the height of the bottom plate 7 needs to be adjusted, the locking screw 11 can be loosened, and the position of the mounting ring 10 on the pole 3 can be adjusted in the vertical direction. When the position of the slider 13 needs to be adjusted, the installation can be adjusted synchronously The fixed position of the ring 10 is enough, the operation is simple and practical, and the practicability is strong.

The support rod 2 is a steel pipe with a hollow inside, and a screw rod 14 is arranged inside the top end, and the top of the support rod 2 is rotated to be provided with an adjusting screw barrel 15 for adjusting the elongation of the screw rod 14, and the two ends of the adjusting screw barrel 15 are symmetrically provided with operating Handle; the top of the screw rod 14 is provided with a top plate 16, and the top plate 16 is provided with a square steel support beam 17 along the length direction of the full hall support 1. The top plate 16 is preferably set to U-shaped, so that the square steel support beam 17 on it is limited and supported; by rotating the adjusting screw barrel 15, the screw rod 14 is controlled to stretch out from the support rod 2, so that the square steel support beam 17 can be quickly The top is tightly installed at the designated position of the full-wall bracket 1, which improves the convenience of installation and disassembly.

The support rod 2 is fixedly connected with the floor bracket 1 by bolts, and the bottom end of the support rod 2 is rotated to be provided with a threaded adjustment cylinder 18, and the two ends of the threaded adjustment cylinder 18 are symmetrically provided with operating rods, and the threaded adjustment rod 19 is moved on the support rod through the threaded adjustment cylinder 18. 2; the threaded adjustment rod 19 is connected with the moving roller 5; by turning the threaded adjustment cylinder 18, the movement of the threaded adjusting rod 19 in the support rod 2 can be realized, thereby achieving the purpose of adjusting the height of the moving roller 5 and realizing the moving roller 5 and the support conversion between the base plate 7.

When the utility model is in use, when the top plate 16 of the construction channel reaches the condition of demoulding, adjust the height of the jacking that is arranged on the top of the full hall support 1, drop the square steel and the formwork that are arranged on the jacking, and drop the mobile roller 5 at the same time so that it can be aligned with the mold. The moving track 6 below is in contact, and the moving roller 5 is used to provide support for the entire floor support 1, and then the bottom plate 7 on the bottom bracket is raised by adjusting the installation ring 10 to separate it from the ground, and finally the power traction equipment is set on the floor support 1 In front of the specified position, just drive the full-wall support 1 to move. In order to ensure the stability and safety of the full-wall support 1 when moving, the speed is controlled within 1m/min to ensure that the full-wall support 1 moves to the designated position in a stable and orderly manner; when moving After it is in place, adjust the bottom plate 7 to be in contact with the ground, raise the moving roller 5, and then raise the top support to a specified height. Through the migration operation of the full hall bracket 1, it can be used multiple times in the same construction passage after one assembly. It is only necessary to convert the rods and support systems when moving each time. Compared with rebuilding, it is extremely convenient. The labor intensity is greatly reduced, and the construction efficiency is improved. At the same time, the original support is not removed, and the impact loss of the support material is avoided every time it is disassembled, and the service life of the support material is prolonged.
