Description

Technical Field

[0001] The utility model relates to the technical field of culvert construction support, and specifically, to a simple lining steel formwork trolley for small-section culverts. Background Art

[0002] Under normal circumstances, the full hall scaffold method is adopted for the construction of small-section culverts. Although the culvert size is small, the scaffold needs to be installed and removed back and forth, consuming a large amount of labor and time.

[0003] Taking the construction bid No. 1 of the water conveyance and irrigation project of the Xixiayuan Water Control Project in Henan Province as an example. There are 140 box culvert structures in this bid section, distributed in 9 buildings, with dimensions of 3.5*3.5m, 3.0*3.0m, 1.8*1.8m, and 1.6*1.6m, four types. It has the characteristics of large quantity and non-uniform dimensions.

[0004] In the traditional scheme, temporary scaffolds are erected according to the situation of each culvert. However, due to the large quantity and workload, frequent disassembly and assembly result in low efficiency of this method.

[0005] At present, the general steel formwork trolley on the market is composed of conventional materials such as steel pipe scaffolds, channel steels, winches, and rollers. However, the steel formwork trolley itself occupies a relatively high height and is more suitable for use in large box culvert structures. It has insufficient adaptability to small-section culvert structures of the aforementioned dimensions, and it is difficult to purchase a suitable steel formwork trolley.

[0006] To sum up, there is no good solution for the current construction needs of small-section culverts, and it is necessary to develop a trolley structure that is easy to move, does not need to be disassembled and assembled frequently, and improves construction efficiency in a timely manner. Content of the Utility Model

[0007] The purpose of the utility model is to overcome the deficiencies of the prior art, and thus provide a simple lining steel formwork trolley for small-section culverts that is easy to move, does not need to be disassembled and assembled frequently, and improves construction efficiency.

[0008] To achieve the above purpose, the technical solution adopted by the utility model is: a simple lining steel formwork trolley for small-section culverts, including a winch, a steel wire rope, a trolley, rollers, and a scaffold;

[0010] The scaffold is a frame structure, including horizontal bars, vertical poles, cross braces, top supports, and fasteners. The lower parts of the vertical poles located on the outermost side are inserted into the jacks of the longitudinal base;

[0011] The roller is detachably installed at the bottom of the transverse base;

[0012] The winch is connected to one or more transverse bases through a steel wire rope.

[0013] Preferably, the longitudinal base is formed by welding two channel steels with their openings facing each other, and the jacking holes are formed in the joint area where the two channel steels are spliced.

[0014] Preferably, the transverse base is formed by welding two channel steels with their openings facing each other.

[0015] Preferably, the transverse base is fixedly welded to the longitudinal base through a number of vertical ribs, and the bottom end of the transverse base is higher than the top end of the longitudinal base.

[0016] Preferably, in the state after the roller is installed, the longitudinal base is off the ground; in the state after the roller is removed, the longitudinal base touches the ground.

[0028] Next, through specific embodiments, the technical solutions of the present utility model will be further described in detail.

[0029] As Figures 1 - 4 shown, a simple lining steel formwork trolley for a small-section culvert includes a winch 1, a steel wire rope 2, a trolley 3, a roller 4 and a scaffolding 5.

[0030] The trolley 3 includes a longitudinal base 31 and a transverse base 32. The longitudinal base 31 and the transverse base 32 are welded together. The bottom end of the transverse base 32 is higher than the bottom end of the longitudinal base 31. The winch 1 is connected to one or more transverse bases 32 through the steel wire rope 2. A number of sockets 33 are arranged along the length direction of the longitudinal base 31 for inserting the vertical poles of the scaffolding 5.

[0031] The structure of this trolley 3 is greatly simplified compared with the traditional trolley. The power part is removed and replaced by the traction of the winch 1 through the steel wire rope 2. The support structure only retains the longitudinal base 31 and the transverse base 32. The overall thickness is greatly reduced and the structure is greatly simplified. Sockets 33 are provided on the longitudinal base 31 to support and limit the scaffolding 5 to ensure the stability of the scaffolding support.

[0032] Specifically, in this embodiment, the longitudinal base 31 is formed by welding two channel steels with their openings facing each other. The sockets 33 are formed in the joint area where the two channel steels are spliced. Similarly, the transverse base 32 is formed by welding two channel steels with their openings facing each other. The number of the longitudinal bases 31 is two, and the number of the transverse bases 32 is at least two.

[0033] The transverse base 32 is welded and fixed to the longitudinal base 31 through a number of vertical ribs 34, and the bottom end of the transverse base 32 is higher than the top end of the longitudinal base 31.

[0034] The roller is detachably installed at the bottom of the horizontal base. Specifically, in this embodiment, the roller 4 and the horizontal base 32 are connected by a bolted base. For example, a base is installed at the lower end of the horizontal base 32, and a vertically protruding bolt is provided on the base. A corresponding bolt hole is provided on the roller 4. Through the cooperation of the bolt and the bolt hole, the roller 4 is restricted from moving relative to the horizontal base 32 in the horizontal direction. In the vertical direction, the gravity makes the roller 4 and the horizontal base 32 not separate from each other.

[0035] In the state after the roller is installed, the longitudinal base is off the ground, and the winch 1 pulls the trolley to move through the steel wire rope 2; in the state after the roller is removed, the longitudinal base touches the ground and serves as the support foundation for the entire scaffolding.

[0036] In actual work, the width between the outer side of the longitudinal base 31 and the bottom corner of the culvert is at least 5 cm. Taking the No. 1 construction section of the water conveyance and irrigation project of the Xixiayuan Water Control Project in Henan Province described in the background technology as an example, the specifications of the trolley need to be designed into four specifications to meet the size requirements of four different box culverts.

[0037] The scaffolding 5 is of a frame structure, including cross bars, vertical bars, scissors braces, top supports and fasteners. Its structural form has no difference from the traditional structure. The lower part of the outermost vertical bar is inserted into the insertion hole of the longitudinal base; the length of the longitudinal base 31 is equal to the length of the scaffolding 5.

[0038] In specific use, the scaffolding can be directly erected based on the trolley, and the outermost vertical bar is inserted into the insertion hole; when it needs to be moved, the steel formwork trolley is lifted as a whole by a jack, which can press against the bottom of the horizontal base, and then the roller is installed, and the trolley is driven to move through the cooperation of the winch and the steel wire rope; when support is required, the steel formwork trolley is lifted as a whole by a jack, and then the roller is removed to make the steel formwork trolley body land on the ground to form a support structure.

[0039] This device can be transferred and used between different box culverts, and can also be transferred and used at different positions of the same box culvert.

[0040] Taking the No. 1 construction section of the water conveyance and irrigation project of the Xixiayuan Water Control Project in Henan Province as an example. There are 140 box culvert structures in this bid section, distributed in 9 buildings, and the sizes are of four types: 3.5*3.5m, 3.0*3.0m, 1.8*1.8m, and 1.6*1.6m.

[0041] The simple lining steel formwork trolley for small-section culverts in this embodiment has completed relevant experimental verification work in this project, and 96 bins of concrete pouring have been completed. Through research on the self-made lining steel formwork trolley, a "flow line" operation mode for culvert construction has been found. By using external traction to quickly transfer the scaffolding, the construction progress of the buildings in this section has been accelerated, the formed formwork and supports have become more stable, and the cumulative errors caused by construction personnel's operation mistakes have been reduced, which not only improves work efficiency but also saves resources.

[0042] A movable steel formwork trolley is formed by using conventional scaffolding erection and formwork reinforcement installation. The movement of the trolley relies on a winch as the external traction force. Each steel formwork trolley is moved to the next bin number by traction, which has produced good economic benefits in terms of quality control, construction period shortening, resource saving, etc.

[0043] Finally, it should be noted that: The above has detailed the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of this patent.
