Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used when a construction material lifted by a lifting device outside a building frame is carried into an inside of a building body through an opening of the building frame, and particularly to the opening. The present invention relates to a simple transfer device for construction materials that can be easily carried in when there are obstacles such as a waist wall.

[0002]

2. Description of the Related Art When a multi-storey building is constructed, interior materials are brought into each floor of the building frame to finish the interior at the stage where openings for attaching windows and entrances are formed. . The material is carried in by hoisting the material from the ground with a hoisting device such as a construction elevator or a crane, and transferring the material into the building body through the openings provided on each floor. In this case, the loading platform of the lifting device on which the material is placed,
When the floor surface of the building body to be transferred is on the same plane, for example, Japanese Utility Model Publication No. 5-62338 (Int.Cl.B60).
Materials can be transferred into the building body using the loading and unloading device disclosed in P 1/00).

However, when the material is to be taken in through the opening for the window, the waist wall exists below the opening, so it is necessary to take in the material through the waist wall. For this reason, the above-mentioned loading and unloading device cannot be used, and it is inevitable that the worker manually takes in the unloading device. In this way, when the materials are manually taken in, the worker may move the heavy object in an unnatural posture across the waist wall, which may hurt his back. Since it is necessary to stop the lifting device at the loading floor, the operating efficiency of the lifting device is significantly deteriorated.

Therefore, an apparatus that enables the transfer of materials even when the waist wall is present has been proposed by Japanese Patent Laid-Open No. Hei 5-162993 (Int.Cl.B66F 7/08). In this transfer device, a table lifter that can be raised and lowered is placed inside the waist wall, and the material loaded on the lifting lifter transfer device as a lifting device is transferred to the waist wall via a roller conveyor that is placed at the lift port. It is designed to be transferred to the above table lifter while straddling it.

[0005]

However, in the conventional transfer device for transferring the material to the inside of the building body by straddling the waist wall, the roller arranged between the lifting lifter and the table lifter is used. A roller conveyor is provided not only on the conveyor but also on the upper surface of the lifting lifter transfer device and the upper surface of the table lifter, and the materials and pallets are moved on these roller conveyors.
However, when the material and the pallet move on the roller conveyor in this way, the moving material and the pallet are vertically vibrated by the uneven portions formed between the rollers of the roller conveyor, and the transfer device and the waist wall are moved. A gap or a step is formed at the joint between the straddling roller conveyor and between the roller conveyor and the table lifter, and when the pallet passes through this joint, a large vibration occurs, and the load on the pallet is loaded. It may collapse.

In addition, a large pushing force is required to move the pallet through the gaps and stepped portions of the concavo-convex portion of the roller conveyor and the joint portion. Therefore, in order to transfer the load on the pallet from the lifting lifter to the table lifter, it is necessary to use a plurality of workers who support the load from both sides and move it with a large pushing force so as not to cause the load collapse, which saves labor. It will be difficult to achieve,
Poor scaffolding reduces workability. In addition, the table lifter body is also heavy, and it takes time to carry it in and out of a construction elevator or the like when moving between floors.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and the material lifted by the lifting device outside the building body is located inside the building body through the waist wall without resorting to manual labor. It is an object of the present invention to provide a simple transfer device for construction materials, which can be carried into a container, and which can prevent falling due to load movement when carrying in a material and can perform transfer work safely and quickly. .

[0008]

In order to achieve the above object, a simple transfer device for construction materials according to claim 1 of the present invention is a waist wall which is higher than the floor surface in an opening for receiving the materials. In the simple transfer device for construction materials used when loading the material lifted by the lifting device outside the building body into the inside of the building structure where the obstacle part is provided, the floor inside the building structure And a transfer frame disposed on the surface, and the transfer frame is expandably and contractibly provided. The transfer frame is expanded and contracted using the transfer frame as a support portion and the material lifted by the lifting device is passed through the waist wall to the building frame. A fork mechanism carried inward, a support mechanism provided on the transfer frame and detachably fixed to the floor surface and the ceiling member, and a support mechanism provided on the support mechanism.
The support mechanism to the extension and contraction direction of the fork mechanism.

The adjusting means is provided.

Therefore, in the simple transfer device for construction materials according to the present invention, the building lifted by the lifting device by the extendable fork mechanism provided on the transfer frame inside the building body. Since the material outside the body can be transferred to the inside of the building through the waist wall, after placing the material outside the building on the fork mechanism, the material is automatically transferred without relying on manpower. It can be transferred to the inside of the building. At this time, when the material is transferred from the outside of the building to the inside of the building by the fork mechanism, the load transfer of the material occurs, but the support frame provided on the transfer frame causes the transfer frame to move to the floor surface and the ceiling member. Since it can be securely fixed to the building body side by fixing it to the fork mechanism, the fork mechanism can be reliably supported and, in turn, the material can be prevented from falling. Also, when the transfer frame is moved, the width adjusting means
To keep the support mechanism shortened in the width direction.

According to a second aspect of the present invention, there is provided a simple transfer device for construction materials, wherein the fork mechanism having the structure of the first aspect is provided on the transfer frame so as to be able to move up and down. And an inward extending means for extending in a reverse direction from a shortened state to reach a carriage arranged on the floor surface.

Therefore, in the simple transfer device for construction materials according to the second aspect of the present invention, the fork mechanism provided on the transfer frame so as to be able to move up and down is raised to a position slightly higher than the waist wall to extend outwardly. Activating and extending outward, the fork mechanism can reach the load platform and take up material on the load platform. Then, by shortening the fork mechanism that takes in the material, the material can be carried into the inside of the building body through the waist wall without requiring a pushing force manually. In this shortened state, the vertical position of the fork mechanism is adjusted as necessary, and then the inward extension means is operated to extend in the opposite direction, so that the material loaded into the fork mechanism does not depend on the pushing force of the hand truck. The material can be transported to and transferred to the cart in this state.

Further, a simple transfer device for construction materials according to a third aspect of the present invention is a transfer frame having the structure according to the above-mentioned first or second aspect, on the floor surface in a state where the fixing by the support mechanism is released. It is configured by providing a moving means that can move freely.

Therefore, in the construction material simple transfer device of the third aspect, when the material transfer operation is not performed,
It is possible to move the transfer frame to a place where it does not interfere with work by operating the moving means and keep it, and to move the transfer frame to that place when carrying in materials from another place. Therefore, it is not necessary to provide a plurality of transfer frames on the same floor surface.
