Description

  The present invention relates to an outer wall material mounting system. Specifically, the present invention relates to an outer wall material attachment system for attaching an outer wall material to a building under construction.

  Conventionally, outer wall materials such as curtain walls and precast concrete plates are attached by the following procedure. That is, a part of the ground surface in the site site is divided into a construction yard, and the outer wall material is unloaded from the carrying vehicle to the construction yard and accumulated. Then, the outer wall material is lifted from the building yard by a lifting crane and attached to a predetermined position (see Patent Document 1).

Japanese Patent Laid-Open No. 7-76932

  However, if a construction yard is provided in a part of the site site, it will be delayed to start the construction of the construction yard part, and it will be necessary to bypass the construction yard and provide lead-in / out leads. There was a problem that process management became difficult.

  Therefore, in recent years, it has been proposed to use a predetermined floor of a building as a building yard. That is, the outer wall material is carried in and accumulated in the building yard, and the accumulated outer wall material is transported to the end of the floor, lifted by a lifting crane, and attached to the building.

Here, when the length of the outer wall material is long with respect to the height of the floor serving as the building yard, the procedure for lifting the outer wall material is as follows.
First, two trolleys are prepared, and the upper side of the outer wall material is placed on one of the trolleys, and the lower side of the outer wall material is placed on the other trolley so that the outer wall material is laid substantially horizontally. Here, a cart that supports the upper side of the outer wall material is an upper support cart, and a cart that supports the lower side of the outer wall material is a lower support cart. Specifically, the lower support carriage supports a position below the outer wall material and closer to the center, and is hidden under the outer wall material.

Next, the worker pushes the outer wall material and carries it to the floor end, and arranges the upper side of the outer wall material on the floor end side.
Next, the lifting hook of the lifting crane is lowered along the outer wall surface of the building, the upper side of the outer wall material is supported by the lifting crane, and then the upper support carriage is removed.

Next, lay an end thick square on the floor behind the lower support carriage, wind up the lifting crane so that the lower edge of the outer wall rests on the end thick square, and lift the upper side of the outer wall upward Build up the outer wall material.
Thereafter, the lifting crane is further wound up and pulled out while lifting the outer wall material upward. At this time, the outer wall material rotates around the upper side by its own weight, and the lower side of the outer wall material is pulled outward by this rotational force. Therefore, an assistance rope is connected to the lower end side of the outer wall material, and an operator pulls the assistance rope inward to adjust the movement of the outer wall material on the lower end side.

  In the above method, when the outer wall material is moved, the lower support cart is hidden under the outer wall material, so that the worker moves by pushing the outer wall material instead of the lower support cart. Also, when building up the outer wall material, it was necessary for the workers to fine-tune the force of the assistance rope. Therefore, it is difficult to control the outer wall material with high accuracy, and the work efficiency of the outer wall material mounting work has been reduced.

  An object of this invention is to provide the outer wall material attachment system which can improve the work efficiency of an outer wall material attachment operation | work, even when the length of an outer wall material is long with respect to the height of the floor used as a building yard.

  The outer wall material mounting system according to claim 1 is an outer wall material mounting system for mounting an outer wall material to a building under construction, and a floor is constructed on a predetermined floor of the building and supports a lower side of the outer wall material. A carriage capable of transporting the outer wall material within the predetermined floor, and the carriage has a carriage main body on which a lower end edge of the outer wall material is placed and can travel on the floor, and a rear side from the carriage main body. And a grip portion extending upward.

  Examples of the outer wall material include an aluminum curtain wall and a precast concrete plate.

According to this invention, the lower end edge of the outer wall material is placed on the carriage, the lower end edge of the outer wall material is supported by the carriage, and the grip portion extending rearward and upward from the carriage body is provided.
Therefore, when the carriage is moved forward or stopped, it is not necessary for the worker to operate in a leaning posture by gripping the gripping part, and the cart can be operated in a standing posture. The movement of the outer wall material can be controlled with high accuracy.
Moreover, since the holding | gripping part is extended back, an operator can leave | separate from the edge part of a floor, and the safety | security of work improves.

Moreover, when building up the outer wall material, the lower wall edge of the outer wall material is built up in a state of being placed on the carriage. Therefore, compared with the conventional case where the lower end edge of the outer wall material is placed on the end thick square member and built up, the operator's struts are effective, so that the cart can be operated reliably.
Also, even when the trolley is pulled toward the outside of the floor due to the weight of the outer wall material when the outer wall material is erected, the operator can operate the trolley directly with the gripping part, so that the support rope can be Compared to the case where the carriage is indirectly operated by pulling, the outer wall material can be controlled safely and accurately.

  As described above, even when the length of the outer wall material is long with respect to the height of the floor serving as the building yard, the work efficiency of the outer wall material mounting work can be improved.

  The above outer wall material mounting system preferably further includes a second carriage that supports the upper side of the outer wall material and can transport the outer wall material within the predetermined floor.

  According to this invention, while supporting the lower side of an outer wall material with the above-mentioned trolley | bogie, the upper side of an outer wall material is supported with a 2nd trolley, and an outer wall material is laid down and it is set as a substantially horizontal state. And these two trolley | bogies are pushed and conveyed to a floor edge part. Therefore, the outer wall material can be reliably transported in the horizontal direction while maintaining the substantially horizontal state.

The outer wall material mounting system according to claim 1 , further comprising a jumping portion provided on the floor of the predetermined floor and jumping outward from an end portion of the floor, and the carriage has an upper surface of the jumping portion. It is possible to run.

  When the outer wall material is erected and lifted upward, the upper side of the outer wall material is suspended by the lifting crane and is located along the outer wall surface of the building, that is, at the floor edge, but the lower side of the outer wall material is the lower side. Since it is supported by the side support carriage, it is located inside the outer wall surface of the building, that is, inside the floor edge. Therefore, if the timing for lifting the outer wall material upward and the timing for moving the lower support carriage toward the floor end are not synchronized, the outer wall material and the lifting crane may be in contact with the building and be damaged.

  So, according to this invention, the protrusion part which protruded outside from the edge part of the floor was provided. Therefore, when the outer wall material is erected and lifted upward, the carriage is moved to the upper surface of the protruding portion and moved to the outside of the floor, thereby positioning the outer wall material as far as possible outside the floor.
