Description

  When waterproofing the surface of a concrete frame such as a flat roof, for waterproofing such as a waterproof sheet stretched joint plate, waterproof drain, headboard steel plate, etc. that are fixed to the concrete frame directly or via a heat insulating material or curing sheet The present invention relates to a fixing member.

  Conventionally, the so-called insulation method, in which a waterproof sheet made of vinyl chloride or olefin resin is partially bonded to the surface of a concrete frame such as a flat roof, is used for waterproof sheet stretched joint plates, waterproof drains, capsaki steel plates, etc. A waterproof construction fixing member is used.

  As a fixing member for waterproof construction, a resin-coated steel sheet coated with vinyl chloride or olefin resin is processed by cutting, bending or pressing, and it is inserted for a fixing tool for fixing to a concrete frame. A hole is provided. For example, as shown in FIG. 4, the resin-coated steel sheet (22) constituting the waterproof construction fixing member (21) has a fixing tool insertion hole (24) formed in a flat shape as viewed from the cross section.

  However, when the fixing member (21) for waterproofing construction is fixed to the concrete frame by the fixture (25) having the head (25a), the head (25a) is the upper surface of the resin-coated steel plate (22). There was a risk of breaking through the waterproof sheet (S) covering the upper part of the waterproof sheet.

  Therefore, as shown in FIG. 5, a concave housing that can accommodate the head of the fixture in a state where the outer surface is processed on the upper surface of the resin-coated steel plate (32) and the flat portion (32b) that is not subjected to the outer processing is left. There has been proposed a waterproof construction fixing member (31) provided with an insertion hole (34) for inserting a leg portion while forming a portion (33). At this time, the edge (32a) protrudes obliquely downward. (See Patent Document 1)

The waterproof construction fixing member (31) having the outer diameter processed as described above is provided with the accommodating portion (33) for accommodating the head of the fixing tool, so that the head of the fixing tool protrudes. In other words, there is no risk of breaking through the waterproof sheet, and the appearance after construction can be secured well.

  However, since the waterproof construction fixing member provided with the accommodating portion capable of accommodating the head portion of the fixture has an edge portion of the insertion hole projecting obliquely downward, the edge portion has a sharp variability. There was a problem of damaging waterproof members such as other fixing members for waterproof construction and waterproof sheets.

  For example, among waterproofing fixing members, waterproof sheet-stretching joining plates are usually stored and transported in a state where a plurality of them are stacked, but they are adjacent to the bottom due to many stacking or vibration during transportation. The resin surface of another joining plate may be damaged. In addition, waterproof construction fixing members such as waterproof drains and Kasagi steel plates are often heavy, and may be damaged on the waterproof construction surface by accidentally dropping them onto the waterproof sheet during construction. Moreover, the human body such as a finger was sometimes injured during handling.

  Many waterproof members are used for a long period of time, and even fine scratches can grow into large scratches over time. It is something that must be prevented.

  In particular, a waterproof member made of a resin-laminated steel sheet in which a resin is laminated in a thin film is easily damaged on the surface.

  For such a problem, it may be possible to take measures such as individually wrapping the waterproof construction fixing member with a cushioning packaging material such as a pneumatic film from the time of storage until just before use. However, such countermeasures have other problems such as increasing the construction work labor and increasing the amount of extra materials.

  Then, this invention is providing the fixing member for waterproof construction which cannot make it damage other waterproof members easily and can make construction workability | operativity favorable.

  As a result of earnest research, the inventor focused on the shape of the edge of the insertion hole of the fixing member for waterproofing construction provided with a housing portion capable of housing a conventional fixture, and by changing the shape, the above It has been found that a fixing member for waterproofing construction that can achieve the object can be obtained.

  That is, the waterproof construction fixing member according to the present invention is a waterproof construction fixing member in which an outer shape is formed on the upper surface of the resin-coated steel plate to form an insertion hole for inserting the housing portion and the leg portion for housing the head of the fixture. Then, the gist of the fixing member for waterproofing construction is characterized in that the edge of the insertion hole protrudes in the horizontal direction.

  The fixing member for waterproof construction according to the present invention is characterized in that the edge of the insertion hole protrudes in the horizontal direction, so that the edge does not act as a sharp burr, and it can be stored, transported, or Even if they come into contact with other waterproof members during waterproof construction, they are prevented from being damaged. It is difficult to damage human bodies such as fingers and improves workability.

  Moreover, since it has the accommodating part which can accommodate the head of a fixing tool, even after construction, the waterproof sheet covered above is not pierced, and the durability in waterproofing construction is improved. The appearance after construction can also be kept good.

  Moreover, since the insertion hole for fixtures can be formed only by performing external processing on the resin-coated steel sheet, it is excellent in economic efficiency.

  Furthermore, the fixing tool is struck by a nailing machine, and the obtained fixing structure is obtained by pushing the edge of the insertion hole of the fixing member for waterproofing construction into the concrete frame, so that high fixing strength can be obtained.
