Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a waterproofing layer constructed on the upper surface of a concrete roof, for example, when the waterproofing layer deteriorates over time, instead of replacing the waterproofing layer with a new waterproofing layer, a durable sheet such as a corrugated sheet is provided on the upper surface. The present invention relates to a mounting structure for fixing a channel material serving as a mounting base of a roofing material on a flat roof or the like when a construction method of layering roofing materials having excellent properties is adopted.

[0002]

2. Description of the Related Art Conventionally, in order to repair a roof with an aged waterproofing layer, a method of removing a waterproofing layer such as a damaged waterproofing sheet and replacing it with a new waterproofing sheet has been generally adopted. Came. In such a case, a method has been adopted in which the trouble of peeling the old tarpaulin is omitted and a new tarpaulin is laminated thereon. However, the durability of the conventional waterproofing construction layer is considerably shorter than the life of the building, and the repair work has to be repeated quite frequently. In addition, when a new waterproof sheet is provided on an old waterproof sheet, there is also a problem that both are hardly compatible.

On the other hand, when an old slate roof, such as a factory or a warehouse, is damaged, there is no need to remove the old roof material, and a new roofing material such as a corrugated metal sheet is laid on top of that. It has often been adopted.

[0004] Therefore, even for a concrete roof, the aged waterproofing material layer is left as it is,
If roofing materials with excellent durability are laid in the same manner as in the case of the above-mentioned factory or the like, the number of times of repair of the flat roof can be greatly reduced. Alternatively, in the case of a newly-built building, it is conceivable to use the above-mentioned method of laying roofing materials in place of the conventional waterproof construction as a rain-floating method for a flat roof.

[0005] However, a concrete roof has a thickness that is incomparable to that of a roofing material such as a slate, so that it is very confusing to fix the roofing material. However, it is conceivable to use concrete nails or special stud bolts for embedding in existing concrete structures. However, considering the invasion of typhoons and the like, existing concrete nails and stud bolts have extremely insufficient pull-out strength.

Accordingly, the present inventor has proposed an efficient stud bolt installation suitable for the purpose of firmly and reliably planting a stud bolt for mounting a roofing material on an existing concrete rooftop or the like. After inventing the construction method,
-3488026 ".

The outline of the invention of the prior application is shown in FIG.
It will be explained by. First, a bolt hole c is formed in the thick flat roof C. Then, the pipe 11 having the rubber bag 12 tied to its lower end is inserted into the bolt hole c, and the reaction-curable synthetic resin stock solution 13 is injected into the rubber bag 12 protruding to the back side of the flat roof C. Then, stud bolt E is dropped.
Then, the resin bolt head 14 for retaining is formed at the lower end of the stud bolt E as the resin hardens. 15 is
It is a nut for drop prevention screwed to the upper end of the pipe 11.

In this way, even if the stud bolt E cannot be inserted from under the roof under the flat roof C, the stud bolt E is quickly and firmly planted from the upper side of the flat roof C. I can do it.

Thereafter, a channel material B serving as a base for mounting a roofing material (not shown) is fixed to a predetermined position on the upper surface of the flat roof C by a substantially L-shaped holding metal 16 and a nut 17 inserted through a stud bolt E. To be fixed.

[0010]

However, according to the above-mentioned prior art method, as shown in FIG. 6, a bolt E, a nut 17, and a retainer are provided on the top surface of a channel material B serving as a mounting base for a roofing material. The metal fitting 16 is in a protruding state. Therefore, as can be understood from FIG. 4 as an embodiment of the present invention, these protrusions hinder the work of mounting the roof mounting member (tight frame) F on the upper surface of the channel member B. become.

The top surface of the flat roof is flat as a whole, but has some irregularities when viewed locally.
On the other hand, the above-mentioned prior invention does not provide sufficient measures for easily mounting the channel material B horizontally. Furthermore, if rain falls during the roofing work, measures to prevent water leakage from the bolt holes will be a major problem, since the location is the roof of an existing building.

Accordingly, an object of the present invention is to provide a construction method in which a roofing material such as a corrugated sheet is laid on a flat roof via a channel material when the waterproofing material layer on the upper surface of the concrete roof is degraded over time. It is an object of the present invention to provide a channel material mounting structure which can easily deal with these problems when employed and can perform roofing work as quickly and reliably as possible.

[0013]

In order to achieve the above-mentioned object, a mounting structure for a channel material on a flat roof or the like according to the present invention comprises a roofing material such as a corrugated sheet or the like on a flat roof whose waterproofing material layer has deteriorated over time. And a stud bolt E planted on a base C such as an existing concrete roof or wall, and a stud bolt E for mounting a channel material through a channel material. And a receiving member A attached to the base C for receiving and supporting the channel material B in a fitted state. The receiving member A has a shape like a metal band plate bent upward in a U-shape. 1a includes a receiving groove portion 1 having a bolt hole 3 through which a stud bolt E is passed, and a square tubular leg portion 2 integrally connected to a lower side of the bottom surface 1a.
A channel material B fitted into the receiving groove 1 with the opening b facing downward is fixed to the receiving groove 1 by welding. It is also characterized in that the receiving member A is formed by bending a single metal plate cut into a predetermined shape.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The present invention and the above-mentioned "Japanese Patent Application No. 9-348026" which is the earlier invention
The main difference from the conventional holding bracket 1 shown in FIG.
6 in place of the fitting A shown in FIGS. 1 to 3.

FIG. 4 shows a reinforced concrete land roof (base) C whose waterproof material layer has deteriorated over time using this metal fitting A.
A state in which a corrugated roofing material D is laid over the channel material B serving as an attachment base (frame material) on the
It is shown as a partial longitudinal sectional view.

E in FIG. 4 is a stud bolt planted on the upper surface of the flat roof C by the method of the prior application.
F is a support fitting (tight frame) that is fixed on the channel material B and directly supports the roofing material D, and has a form in which a metal strip is bent in accordance with the wavy shape of the roofing material D. I have. H is a wooden timber that is arranged side by side on the flat roof C at predetermined intervals, and reliably receives and supports the load of the roof. Then, a heat insulating gap is formed above the flat roof C.

FIG. 5 is a longitudinal sectional view taken along the line YY of FIG. The method of planting the stud bolts E on the flat roof C has already been described in the section of "Conventional Technology", and therefore will not be described here.

The metal fitting A is formed into a three-dimensional shape as shown in FIG. 1 by bending a single metal plate (not shown) cut into a predetermined shape. That is, as shown in FIG. 5, an upwardly U-shaped receiving groove portion 1 for completely inserting the channel material B with the opening b thereof facing downward, and an integrated portion below the bottom surface 1a. And a square tube-shaped leg portion 2 continuously provided at the center.

A long bolt hole 3 through which a stud bolt E passes is provided in the bottom surface 1a. As can be understood from FIG. 1, the leg portions 2 each having a rectangular cylindrical shape have opposing side surfaces 2a, 2a extending downward at right angles from both side ends of the bottom surface 1a, respectively, and a right angle from one side end of each opposing side surface 2a. Opposing side surfaces 2b, 2b extending laterally and reaching another opposing side surface 2a.

Next, in order to fix the channel material B on the flat roof C using the metal fittings A, as shown in FIG.
The long bolt hole 3 of the bottom surface 1a of the receiving member A is inserted. Then, if the metal fitting A is correctly positioned and the nut 4 screwed to the stud bolt E is fastened, the operation of fixing the metal fitting A on the flat roof C is completed simply and quickly.

Next, a large number of wooden timbers H are placed on the flat roof.
Are arranged in parallel with each other at a predetermined interval in the direction perpendicular to the channel material B. After that, the channel material B is dropped into the receiving groove 1 of each metal fitting A.

At this time, if there is a location where the flat roof C is locally concave, at that location, the lower surface of the channel material B extends to the bottom surface 1a of the receiving groove 1 as shown by the phantom line in FIG. Channel material B
Is kept horizontal.

If the channel material B accommodated in the receiving groove portion 1 in such a state is welded to the side wall 1b, the operation of fixing the channel material B at a predetermined position on the flat roof C is completed. Symbol G indicates this welding location. Similarly, a large number of channel members B are arranged in parallel at a predetermined interval from each other, and are orthogonally arranged on the group of wooden timbers H.

After that, the method of roofing the roofing material D on the group of channel materials B is not so different from the known conventional method. That is, first, as shown in FIG. 4, the tight frame F of the roofing material D is fixed by welding over the entire length of the upper surface of each channel material B.

At the time of this mounting operation, unlike the conventional method shown in FIG. 6, no obstructive protrusions such as the stud bolt E and the holding member 16 are present on the upper surface of the channel material B (see FIG. 6). (See FIG. 5). Therefore, the mounting operation of the support fitting F can be performed accurately, quickly, and easily.

After the mounting of the support fitting F, as shown in FIG. 4, a roofing material D is put thereon, and the roofing material D is fixed to the roofing material D by bolts 5 and nuts 6 protruding from each mountain of the support fitting. Then, the roofing work is completed if the respective mountain parts of the support fitting F are firmly joined to each other.

Even if it rains during the installation work of the channel material B and the roofing material D, even if it rains, the bolt hole c drilled in the flat roof C will have the receiving groove 1 of the metal fitting A and the rectangular cylindrical shape. Since it is surrounded by the legs 2, there is no risk of water leaking into the attic. In order to surely eliminate the risk of water leakage, a caulking material (not shown) may be applied to the place where there is a possibility of the leakage.

The base on which the channel material B is mounted is not limited to the flat roof C, but may be, for example, a concrete wall or the like.

[0029]

As is apparent from the above description, according to the structure for mounting a channel material on a flat roof or the like according to the present invention, practically excellent effects as listed below can be obtained. (A) On the upper surface of the channel material, which is the mounting base of the roofing material, unlike the conventional technology,
Nuts and fittings do not protrude and are completely flat.
(B) Therefore, the work of attaching the tight frame to the upper surface of the channel material can be performed quickly and accurately. (C) Before welding, the channel material can move up and down inside the receiving groove, so even if there are local irregularities on the top surface of the flat roof,
It can easily be mounted horizontally on this flat roof. (D) Since the bolt holes provided on the flat roof are surrounded by the receiving groove of the bracket and the rectangular tube-shaped legs, even if there is rainfall during construction, rain can be reduced by using the caulking material together. Don't worry. (E) The metal fitting can be efficiently mass-produced from one metal plate.
