Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem wherein load must be reduced because a burden of a beam is large in a conventional method for supporting a skeleton and a crane, although a position for installing the crane is an important problem in a building made of reinforced concrete and the construction method for installing the crane on an outer side of the building and adding masts in accordance with progress of the skeleton is used, but the number of horizontal stays and masts to be added for supporting the crane is proportional to height of the building and is increased, thereby increasing cost, and the climbing work to be sequentially performed is continuous and dangerous work at an elevated place, and as a result, the technology for floor-climbing the inside of the building is desirable. <P>SOLUTION: This climbing crane is constituted by providing load sensors on a plurality of beams of the crane for dispersing load of the crane onto the constructed beams at a plurality of stories by beams in a plurality of layers attached to a mast receiving base for supporting load of the climbing crane and providing adjusting machines in supporting parts of the plurality of constructed beams to measure and adjust load acting on the beams and the supporting parts of the beams in order to control load acting on each skeleton. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a climbing crane for constructing a structure, which is relocated to an upper floor constructed sequentially, and relates to a climbing crane that supports a crane load with a plurality of girders.

  The conventional climbing crane is composed of two beams on one floor constructed as shown in Fig. 6 and supports the entire load of the crane, so the reinforcement work when the beam of the frame supporting the load is weak is the constructed room This is a work that requires a lot of manual work because the lifting machine cannot be used, and is close to the opening and is dangerous, and requires time and effort including dismantling.

  So far, when the crane load is distributed to the upper and lower floor beams, there is no technique for measuring and adjusting the load acting on the upper and lower floor beam supports, so the load acting on the frame could not be confirmed.

As shown in FIG. 6, the load from above is transmitted to the lower floor using a reinforcing column and jack, but in order to transmit the negative load to be raised to the lower floor, equipment for pulling the anchor bolt through the lower floor is required.

  The position of crane installation in reinforced concrete construction is an important issue, and a method of installing a crane outside the building and adding a mast according to the progress of the frame is used. The number of masts added is proportional to the height of the building and increases, which is a factor of cost increase.Since the climbing work performed sequentially continues dangerous work at high places, the technology to climb the floor of the building is desired. It is rare.

  As shown in FIGS. 1, 5, and 7, the present invention distributes a load to a plurality of beams constructed by a multi-layered girder attached to a mast cradle that supports the load of a climbing crane. By installing load sensors and adjusters on multiple girders, and measuring and adjusting the load acting on the beam and beam support, the load acting on each frame can be managed. Climbing crane.

  The advantage of the crane with the load sensor and adjuster of this invention is that even in buildings where floor climbing was impossible due to insufficient strength of the frame, floor climbing can be performed safely by distributing the load to the upper and lower frames. A safe working environment.

  By managing the load applied to each girder and beam support, it is possible to ensure quality during construction and safe crane work without applying excessive force to the beam of the frame.

  Since the crane is installed near the center of the building, it is small in size, improving work efficiency, eliminating the need for additional masts and horizontal stays, and reducing costs.

  As shown in FIGS. 1 and 2, the present invention is a climbing crane 16 that performs floor climbing, includes a lifting device 2 that slides a mast 1, and is supported by a built frame. A load sensor 10 is provided in the upper girder 4 girder 5 of the crane characterized in that the load is distributed to a plurality of beams 12 constructed with the upper girder 4 and the girder 5 attached to 3. A climbing crane in which the adjuster 6 is provided in the support portion 23 and the load acting on each support portion 23 is measured and adjusted, so that the load can be distributed and managed to each beam 12.

    As shown in FIGS. 1 and 4, the mast cradle 3 is provided with two layers of upper girders 4 and 5, and the load sensor 10 and the adjusting device 6 are provided on the support portion 23 of the upper girder 4 and the constructed beam 12. A climbing crane that can measure and adjust the load applied to the four support parts of the upper girder 4.

    As shown in FIGS. 1 and 2, the upper girder 4 and the girder 5 are provided on the mast base, the load sensor 10 and the adjusting machine 6 are provided on the support part 23 of the beam 12 constructed with the upper girder 4, and Climbing crane that can measure and adjust the load acting on 12

  As shown in FIGS. 1 and 4, two-layer upper and lower girders are provided, and a load sensor 10 and an adjuster 6 are provided on the support part 23 of the beam 12 constructed with the upper and lower girders 4 and 5. A climbing crane that can measure and adjust the load applied to both support parts of the girder 5 and can measure and adjust the load applied to the beam 12 by increasing or decreasing the shim liner 9 of the adjuster.

  As shown in FIGS. 3 and 7, load sensors 10 are provided on the upper girder 4, the girder 5, and the lower girder 30 attached to the mast cradle 3, and each of the three layers of the folding girder 24 and the three-layer floor beam 12 constructed. The climbing crane which can measure and adjust the load which acts on each support part 23 by adjusting the wedge 8 provided in the support part 23 in and out.

  In the construction work of a concrete building, the present invention can use the floor climbing method by dispersing the beams on the second floor when the strength of the beams does not support the crane load on the first floor.
