Technical Field

The present invention relates to a device for transporting and installing a cheolgolbo required in the basement of the building to which the top-down method is applied in the basement floor, and a method for transporting cheolgolbo using the same.

Prior art

Top-down method is one of the methods of constructing underground structures that simultaneously constructs superstructure and sub-grade structures in urban areas. Underground wall construction prevents settlement of nearby ground and buildings, To prevent damage of underground buried ground, construct underground continuous wall (high rigid wall such as Diaphhragm Wall or Slurry Wall), and excavation for construction of underground structure after construction is excavated from the ground floor to the ground and at the same time, ground frame ( It is a method developed to expect the stability of the underground construction and the shortening effect of the entire air by constructing the superstructure.

Top-down method is widely applied to large-scale building construction in urban redevelopment projects such as close construction, large-area excavation excavation, near site and narrow working area, and top-down method is applied. As mentioned above, it has been widely used in Europe, Japan, Hong Kong, Taiwan, etc. due to the advantages of safety and shortening of air during construction, and there is a high interest in the top-down method in Korea, and the application examples are increased. Is in the trend.

The advantages of the top-down method are as follows: ① As the underground sphere replaces the belt and brace, it is possible to minimize the construction cost due to the underground excavation. ② The ground floor can be used as a work place. It has a great effect on the structure. ③ High rigidity Diaphragm Wall is used, and underground sphere supports the underground continuous wall in place of Wall and Strut to minimize the effects of surrounding ground settlement and building settlement. ④ the ground frame can be constructed separately from the excavation work, so that the entire air can be shortened by underground excavation air, and ⑤ the underground excavation work after the first floor of the ground is installed. It is hardly received and can reduce psychological anxiety when digging deep seas and prevents complaints such as noise and vibration. This line is available.

In addition to these advantages, the top-down method also has the following disadvantages.

① Since the slab is constructed from the basement floor downward, subsequent trenches will inevitably work under the slab. Therefore, the efficiency of excavation work is deteriorated and the excavation construction cost is increased. ② The size of opening for excavation is limited according to the type of building structure, so it is expected to be difficult to carry out excavation. ③ It is difficult to deal with the joint of underground continuous wall and building concrete slab, the joint of pillar and retaining wall and building concrete slab. ④ As the underground construction is carried out one by one, the joint length of the column reinforcement increases and the cost of supporting concrete for slab casting is additionally generated, and ⑤ building concrete slab plays the role of supporting the underground continuous wall. When designing, it is necessary to minimize the design change through sufficient discussion and review. On-site quality control and urgent design change processing are required.

In the top-down method as described above, the cheolgolbo required during the construction of the basement floor is a vertical transport of the material using a crane through the opening of the ground floor, and the horizontal transportation of material in the basement floor is used for the excavation work of the basement floor. It is done using an excavator.

However, according to the conventional horizontal transportation method, as shown in Figure 1, the wire is connected to the cheolgolbo, the wire connected to the cheolgolbo is moved to the state attached to the lifting hook attached to the bucket of the excavator (Bucket).

As such, when heavy and long materials such as cheolgolbo are transported while the wires are unstablely mounted on the excavator bucket, if the right and left equilibrium is not properly maintained, the materials fall to one side and fall to the floor. Along with the risk of accidents, there is a problem of lowering work efficiency.

In addition, in order to safely and accurately seat heavy and long materials such as horizontally transported steel gimbal in the installation place, the workers must hold the wire on both sides of the wire supporting the steel gimbal and move it to the left or right to rest the steel gimbal at the installation place. When the left and right balance of the cheolgolbo is displaced during such work, the cheolgolbo is inclined to one side, there is a high risk of safety accidents of workers and it is also difficult to lay down the cheolgolbo accurately in the installation place of cheolgolbo.

The object of the present invention created to solve the above problems is as follows.

First, it is an object of the present invention to provide a means for easily moving horizontally heavy materials, such as cheolgolbo in the basement floor for the top-down method.

The body portion 200 has a rack gear 212 is attached to the piston rod is provided with a swing cylinder 210 to interlock with the pinion gear 112 of the rotary pin 110, according to the operation of the swing cylinder 210 The unit 200 may be pivoted at a predetermined angle in a state of being coupled to the boom bar coupling unit 100.

The lower surface of the body portion 200 is provided with a cheolgolbo binding groove 220 for accommodating the cheolgolbo and when the cheolgolbo is lifted by the lifting chain part 300, the upper part of the cheolgolbo is seated in the cheolgolbo binding groove 220 is It is to be stably fixed to the body portion (200). Therefore, the shape of the cheolgolbo binding groove 220 is to match the upper cross-sectional structure of the cheolgolbo.

As shown in Figure 2, the cheolgolbo fastening groove 220 may be formed to protrude downward from both ends of the lower surface of the body portion 200. When the steel beam binding groove 220 is configured to protrude downward from both side end portions of the lower surface of the body portion 200 as described above, the steel frame beam binding groove 220 is configured to be detachable from the body portion 200 to form an upper cross-sectional structure of the steel frame beam. And can be used to freely replace the appropriate cheolgolbo binding groove 220 to fit the size.

Body 200 has a mounting base 230 is formed to protrude in the opposite direction to the boom coupling portion 100 as shown in FIG.

Mounting pedestal 230 serves as a pedestal for supporting the body portion 200 during storage to separate the present invention from the boom of the excavator.

The lifting chain part 300 is a lifting chain 310 having a connecting link 312 for connecting the cheolgolbo to the connecting pin 311, the lower end of which one end is provided at the upper end of the lifting chain 310.
