Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixture for fixing the peripheral edge of a pine-like object to the surface of another object.

This fixture is used, for example, when fixing an insulating mat to the side of a paper pulp drying drum. The insulating mat is made by covering an insulating material such as glass wool or rock wool with a heat-resistant sheet, and is about 4 to 5 cm thick. By fixing such a heat insulating mat to the side surface of the drying drum, the amount of drying steam in the drying drum can be saved and uneven drying can be prevented.

This type of insulating mat itself has been known for some time. However, there was no simple means to fix this insulating mat to the drying drum, so it was fixed with bolts or nuts. In this method, it is necessary to position and drill the fixing point on the metal surface to be fixed, which is not an easy task.

The present invention has been made to overcome this drawback and aims to provide a fixing device that can be easily attached to any surface where the head of the bolt is located.

The fixing device of the present invention that achieves this purpose includes a bolt cover that accommodates the bolt head protruding from the surface to be fixed, and a connecting member that connects the bolt cover and the bolt head, the bolt cover being inserted through the bolt cover and the bolt head. a connecting member consisting of a small bolt that reaches the bolt head;
The present invention is characterized in that it consists of a bolt shaft protruding approximately at the center of the bolt cover, and a holding member for tightening a mat-like object passing through the bolt shaft, the holding member consisting of a holding washer and a tightening nut.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

The fixture 1 of the present invention mainly includes a bolt cover 2, a connecting member 3, a bolt shaft 4, and a holding member 5.

The bolt cover 2 is for accommodating the bolt head 6 on the surface to be fixed, and is shaped like an upside-down deep round plate. It is necessary to prepare several different sizes depending on the size of the bolt head to be accommodated. The bolt head 6 to be accommodated is usually hexagonal and does not fit well with the circular bolt cover 2. Therefore, a plurality of coupling members 3, usually two or three, are provided at appropriate locations on the bolt cover 2. The coupling member 3 consists of a small nut 7 whose bottom part is welded and fixed to the inside of the bolt cover 2, and a small bolt 8 inserted through the hole in the small nut and the bolt cover.

The bolt shaft 4 has a base portion 9, and this base portion 9 is welded and fixed to approximately the center of the bolt cover 2.

A presser member 5 that can be attached and detached can be attached to this bolt shaft 4. Pressing member 5
consists of a presser washer 10 and a tightening nut 11 for the presser washer. Preferably, the presser washer 10 is a relatively wide disc as shown in FIG.

The procedure for fixing a pine-like object using the fixing device of the present invention is as follows.

Presser member 5 (presser washer 10 and tightening nut 1
1) The bolt cover 2 of the fixing tool 1 in the removed state can be covered with the bolt head 6 protruding from the surface to be fixed. Next, the fixture 1 and the bolt head 6 are firmly connected by the connecting member 3 (small nut 7 and small bolt 8) of the bolt cover 2. It is preferable that the small bolt 8 bites into the bolt head somewhat.

Next, a hole 13 is made in the mat 12 to be connected, and the bolt shaft 4 is passed through it. A plurality of holes may be provided in advance at appropriate positions and the holes may be utilized.

Finally, the top of the mat 12 is tightened with the presser member 5 (presser washer 10 and tightening nut 11) to complete the fixation.

According to the present invention having the above configuration, the pine-like object can be attached to any surface where the bolt head is located on the surface to be fixed.

Although the above description uses a drying drum and a heat insulating mat as an example, the present invention is not limited thereto, but can be widely used to fix mat-like materials to other surfaces.
