Description

  The present invention relates to a post installation used to prevent a falling block such as a block under construction. The post can be securely strung on both ends, can be safely operated without falling wood, and the work efficiency can be improved. The present invention relates to a post height adjustment device.

  Conventionally, when installing posts used to prevent falling blocks such as blocks under construction, the distance between the posts to be strung has been determined, and it is difficult to reliably straddle with a method that involves putting a wood block etc. in the adjustment. Trees may fall and cause disasters, resulting in poor work efficiency and large disasters.

  However, in the above-described conventional work for preventing the fall of blocks or the like under construction, it is not possible to reliably step on the floor unless a board or the like that fits into the gap is inserted in the adjustment method. In addition, a board or the like falls and causes a disaster, and the work is difficult and the work efficiency is deteriorated. Therefore, there has been a demand for a post height adjusting device that can be easily adjusted in height and that can securely perform work without falling down on the floor board.

  This device was devised in view of the above-described conventional problems and problems, and was devised to solve the problems. By changing the adjustment nut position with respect to the screw shaft, the height can be adjusted freely. Also, to provide a useful post height adjustment device that can prevent the falling of blocks under construction, etc., without using a wood block, etc., and by stroking it at both ends of the post without failing to fall. It is in.

    In order to achieve the above object, the present invention includes a post that supports a load at both ends, a screw shaft that is inserted into the tip of the post, a height adjusting nut that determines a height position, and a receiving metal fitting that receives a direct load. Further, it comprises at least a means equipped with the support shaft adapted to the shape of a block or the like with the receiving surface support shaft of the receiving surface fitting as a fulcrum.

  From the above description, according to the post height adjusting device according to the present invention, when installing as a fall-preventing block for a building under construction, the height can be adjusted freely by changing the adjustment nut position with respect to the screw shaft. It is possible to prevent the falling of blocks under construction by securely striking the post at both ends, and safe work can be done.

It is a top view of the height adjustment apparatus of a post which shows an embodiment of this invention. It is a front view of a post height adjusting device showing an embodiment of the present invention. It is a side view of a post height adjusting device showing an embodiment of the present invention. It is sectional drawing of the height adjustment apparatus of the post which shows embodiment of this invention.

  Hereinafter, the present invention will be described more specifically based on the embodiments of the invention described in the drawings.

1 is a plan view of the post height adjusting device, FIG. 2 is a front view of the post height adjusting device, and FIG. 3 is a side view of the post height adjusting device. FIG. 4 is a sectional view of the post height adjusting device.

  When the post height adjustment device is installed as a fall prevention for blocks under construction, the height can be adjusted freely by changing the adjustment nut position with respect to the screw shaft, and the post height adjustment device can be stomped at both ends of the post without fail. In this way, it is possible to prevent the building blocks from falling down and to work safely. A post (5) that supports the load at both ends, a screw shaft (1) that is inserted into the tip of the post (5), a height adjustment nut (4) that determines the height position, and a receiving metal fitting that receives the load directly ( 2) and height adjustment of a post mainly composed of a receiving surface of the receiving surface fitting (2) on which the receiving shaft (3) is mounted so that the receiving surface is matched to the shape of a block or the like with the supporting shaft as a fulcrum The apparatus will be described.

  1, 2, 3, and 4, the screw shaft (1) is drilled at the tip so that the support shaft (3) is inserted so that the screw shaft (1) is connected to the receiving surface bracket (2). It is processed so as to be inserted into (2). Further, as the name indicates, the cylindrical portions are processed with trapezoidal male threads, and the height is adjusted by the height adjusting nut (4). A round bar is welded to control the rotation of the screw shaft (1) while the trapezoidal screw machining is performed on the parts inserted into the receiving metal fitting (2). Moreover, the hole processing is given to the same level as the round bar.

  The receiving surface fitting (2) is a part that receives a load such as a block directly, and the receiving surface is made of a circular round plate, and the screw shaft (1) is inserted into the part connected to the screw shaft (1). In this way, the plate is fixed to both sides, and the hole processing for inserting the support shaft (3) is processed on both sides.

  The support shaft (3) is made of a cylindrical round steel and is drilled on both sides. The support shaft (3) is a pin to which the screw shaft (1) and the receiving surface fitting (2) are connected. A flat washer (6) is inserted in a state protruding from both sides of the receiving surface fitting (2), and the split pin (7 ) Is inserted so that the support shaft (3) cannot be removed.

  The height adjustment nut (4) has a trapezoidal female thread that matches the screw shaft (1), and can be set at a position that determines the height of the post to ensure that the falling load of the building block, etc. is strung I can do it. A round bar is welded to the outer periphery to control the rotation. In addition, holes are drilled at the same level as the circle.

  The post (5) constitutes most of the support parts for the fall prevention such as a block under construction, and the plate with a circular round hole is fixed to the post tip on the side where the post height adjustment device is installed. ing. The other side will respond according to the situation.

  Note that the present invention is not limited to the embodiment of the above-described invention, and various modifications can be made without departing from the spirit of the present invention. Moreover, in the form for implementing the said device in this invention, although the front-end | tip of a post which inserts a screw shaft was a round hole process, a female screw process can also be performed so that the position of a height may be determined. The height adjustment nut at that time is used as a lock nut.

  When the post height adjustment device is installed as a fall-preventing block for a building block, etc., it can securely support the falling load of the building block on both sides even if the support interval is decided. It can be done safely, and it can be done safely without the falling of the adjusting panel. Furthermore, it can be installed in a short time and work efficiency is improved.
