Description

[Detailed description of the device]

[0001]

[Industrial applications]

 In this structure, in a structure using an ALC plate or a concrete plate as an outer wall material, a fireproof coating material is used for the purpose of fire prevention in a gap of about 150 mm between the beam portion arranged on the outer periphery of the structure and the outer wall material. The present invention relates to a base metal which is coated but supports a fireproof coating material sprayed at that time.

[0002]

[Prior Art]

 Conventionally, when covering the gap between the beams and the outer wall material that are placed on the outer periphery of the structure, wire mesh is used as the base material that supports the fireproof covering material, and it is processed on site each time according to the width of the gap. Then, it was welded and arranged on the H-shaped steel used as the beam material along the longitudinal direction of the gap, and then the fireproof coating material was sprayed.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional method, it is very troublesome to process the wire netting etc. in accordance with the gap width each time at the site etc., and even in the mounting work, the mounting place is almost all around the outer circumference of the structure under the slab. Moreover, the welding work must be performed, which consumes a great deal of work time, lacks rationality of work, and is very dangerous in terms of safety because the worker performs overhead welding work. There are problems such as.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned conventional problems, and the purpose thereof is that the worker can easily and safely attach the H-section steel to the H-section steel even during the installation work without the work of on-site processing. It provides a base metal fitting that reliably supports when spraying.

As a means for this, at least two or more supporting arms, which are sprayed with a refractory coating material and are provided with attachment portions for engaging with H-shaped steel in the longitudinal direction of the base material to be supported, are characterized in that It is characterized in that the mounting part can be moved back and forth along the longitudinal direction of the support arm.

With the above structure, the fireproof coating is sprayed, at least two or more supporting arms are connected to the supporting base material, and the supporting arm is provided with a mounting portion for locking to the H-shaped steel. There is no need for processing, and it can be easily and safely installed without welding to H-section steel during installation work. In addition, since the mounting part can be moved back and forth along the longitudinal direction of the support arm, if one kind of base material with an appropriate width length is manufactured, many types of base materials can be created according to the gap width between the outer wall material and the beam material. Since it is not necessary to manufacture a base material of width and length, it is rational and very economical, and at the same time, it is possible to reliably and stably support the fireproof coating material even during spraying work. The above-mentioned conventional problems are solved.

【Example】

 FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a side view showing an embodiment of the present invention, in which a supporting arm 1 having an appropriate length and a U-shaped piece 2a are formed. A mounting portion 2 in which a vertically movable bolt 2b is screwed is provided, and the base material 3 having an appropriate size is continuously provided at desired intervals along the longitudinal direction. At this time, the base material 3 is preferably a mesh material or the like having an uneven surface, and a steel bar 4 or the like can be installed at a required position of the base material 3 along the longitudinal direction as a reinforcement of the base material 3. .. FIG. 3 is a perspective view showing an embodiment in which the mounting portion of the present invention can be moved back and forth along the longitudinal direction of the support arm. The mounting portion is formed to have an appropriate length, and a long hole 11a is formed substantially at the center. The supporting arms 11 are continuously provided at the required positions and intervals of the base material 13, and in this case, the base material 13 is formed by forming a portion which overlaps with the long hole 11a of the supporting arm 11 in the shape of a long hole to communicate with each other. To do. Next, a bolt 12b that can move up and down is screwed to the lower piece of the U-shaped piece 12a that can be vertically inserted through the long hole 11a of the support arm 11, and the long hole of the support arm 11 is attached to the upper end of the bolt 12b. A disk-shaped tray 12c having a diameter larger than the width of 11a is fixed to form the mounting portion 12. In this case, the mounting portion 12 and the support arm 11 are separate bodies, and as shown in FIG. 4, when mounting on the H-shaped steel, the upper portion and the lower portion of the U-shaped piece 12a of the mounting portion 12 are By the tray 12c at the upper end of the bolt 12b screwed together, the flange portion of the H steel material and the support arm 11 are put together when they are attached by sandwiching.

FIG. 5 is a schematic cross-sectional view showing a usage state of an embodiment of the present invention, in which the mounting portion 2 is attached to the flange portion of the H-shaped steel B used as a beam material arranged on the outer periphery of the structure by the bolt 2b. It can be attached by tightening. FIG. 6 is a schematic cross-sectional view showing a usage state of an embodiment in which the mounting portion of the present invention is movable back and forth along the longitudinal direction of the support arm. The base material 13 is an H-shaped steel B and an outer wall material A. It is possible to arrange so as to close the gap of the above, and to insert the mounting portion 12 into the long hole 1a of the support arm 11 so that the flange portion of the H-shaped steel B and the support arm 11 are both fixed and fixed. Similarly, the base metal fitting of the present invention is continuously attached to the gap between the outer wall material A and the H-shaped steel B, and then the fireproof coating material C is sprayed.

[Effect of the device]

 As described in detail above, according to the base metal for spraying the fireproof coating material of the present invention, the support arm is attached to the base material on which the fireproof coating material is sprayed, and the mounting portion for locking the H-shaped steel is provided on the support arm. Since it is attached, it can be easily attached to H-section steel without welding in the field, and it can be attached easily to the H-section steel, improving the work efficiency and ensuring the safety of the operator. .. In addition, since the mounting part can be moved back and forth along the longitudinal direction of the support arm, if one kind of base material with an appropriate width length is manufactured, many kinds of materials can be produced according to the gap width between the outer wall material and the beam material. There is no need to manufacture a base material of width and length, which is rational and very economical, and has stable and reliable support for the fireproof coating even during spraying work. It is possible to obtain the above-mentioned useful base metal for spraying the fireproof coating material.
