DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to, for example, when a waterproof layer applied to the upper surface of a concrete flat roof loses its function due to aging, instead of replacing it with a new waterproof layer, the upper surface is replaced with a new waterproof layer. Stud bolts suitable for the purpose of firmly and securely planting stud bolts for mounting roofing materials on flat roofs when a method of laying roof materials with excellent durability such as corrugated sheets is adopted. And a mounting structure.

[0002]

2. Description of the Related Art Conventionally, in order to repair a flat roof having 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 in which a new tarpaulin is laminated on the old tarpaulin without having to peel off the old tarpaulin has often been adopted. However, the durability of the conventional waterproof construction layer is considerably shorter than the life of the building,
The repair work had 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 the two 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 roof 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, the above-mentioned roofing method may be used instead of the conventional waterproofing as a rain roofing method for a flat roof.

[0005]

However, a concrete roof made of concrete has such a thickness that it cannot be compared with a roofing material such as a slate, so that it is difficult to use a method for fixing 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, an object of the present invention is, for example, when a waterproof material layer applied on the upper surface of a concrete flat roof deteriorates over time, instead of replacing it with a new waterproof material layer, a corrugated sheet or the like is provided on the damaged upper roof. The stud bolts for roofing material installation, in order to layer roofing material with excellent durability,
An object of the present invention is to provide a stud bolt planting method and a mounting structure suitable for the purpose of firmly and surely planting a concrete roof or the like.

[0007]

In order to achieve the above object, a stud bolt planting structure according to the present invention comprises a pipe 2 internally fitted in a through hole provided in a base in an inserted state. And a stud bolt 1 which is inserted into the pipe 2, one end of which is inserted into the bag-like body 3, and the other end of which protrudes to the front side of the base, Body 3
After being filled in an unhardened state, the stopper member 5 made of a synthetic resin or an elastomer and hardened integrally with the stud bolt 1 is screwed into a male screw provided at the protruding end of the pipe 2 on the front side of the base. 2 and a lock nut 4 which plays a role of positioning and the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described.
This will be described with reference to FIGS. This example is
As shown in FIG. 1, a concrete roof (base) 5
When the waterproof material layer 51 provided on the upper surface of the aging member deteriorates over time, instead of re-installing the waterproof material layer 51, as shown in FIG. 2, a corrugated roof having much higher durability than this is provided. Roofing material 5
2 relates to a construction method of laying on a flat roof 50.

[0010] The members shown in Fig. 1 and Fig. 2 will be described briefly. 1 is a stud bolt which is planted in a flat roof 50 and penetrates, and serves as a frame for mounting a roofing material 52. It serves to fix the material 53. 54 is
To make the lower part of the stud bolt 1 penetrate,
It is an insertion hole provided in. Reference numeral 55 denotes a holding member for fixing the channel material 53, which is formed of a substantially L-shaped metal strip. Reference numeral 56 denotes a holding nut screwed onto the stud bolt 1.

Reference numeral 57 denotes a mounting bracket (tight frame) for the roofing material 52, which is made of a metal strip bent in a wavy shape.
A nut 59 is screwed onto a bolt 58 protruding from each peak.

Reference numeral 2 denotes a pipe to be fitted inside the insertion hole 53,
A bag-like body 3 is tied to the lower end of the pipe 2, and a lock nut 4 is screwed to a male screw provided at the upper end. The retaining member 5 is formed by filling and curing the uncured solution of the epoxy resin having the reaction curability in the bag-shaped body 3.

The pipe 2 of this embodiment shown in FIG. 3 is made of hard vinyl chloride, and has an outer diameter that can be inserted into the insertion hole 54,
It has an inside diameter through which the stud bolt 1 can be inserted, and its length is slightly longer than the thickness dimension of the flat roof 50. A bag-like body 3 made of a highly elastic material such as rubber is covered on the lower end of the pipe 2 as shown in the figure, and this state is fixed using a securing material 6 such as a wire. A lock nut 4 with a washer is screwed onto a male screw a provided on the outer peripheral surface of the upper end of the pipe 2.

As shown in FIG. 4, a stud bolt 1 having a predetermined length is provided with a notch b for preventing rotation and a notch c for removing on a peripheral surface of a base 1a. . Base 1a
In the following, a spherical block-shaped retaining member 5 is formed by the method described below.
(See FIG. 1) is fixed and plays the role of a bolt head.
The notches b and c are for preventing the retaining member 5 from idling or falling off the stud bolt 1 when the holding nut 56 is tightened.

Next, a method of planting the stud bolts 1 on the flat roof 50 and subsequently laying the roofing material 52 on the upper surface of the flat roof 50 will be described with reference to FIGS. First, pipes 2 are placed at predetermined locations on the flat roof 50.
Hole 54 for inserting stud bolt 1 covered with
Are formed so as to penetrate as shown in FIG.

As shown in FIG. 6, the pipe 2 to which the bag 3 and the lock nut 4 are attached is inserted into the insertion hole 54. At this time, the lock nut 4 is located near the upper end of the pipe 2. Let me put it. Then, as shown in the figure, a predetermined amount of the uncured stock solution d of the epoxy resin is injected from the upper end opening of the pipe 2 toward the bag-like body 3 using an injector (not shown) for quantitative filling.

After filling the uncured stock solution d, the pipe 2 is pushed in until the lock nut 4 contacts the upper surface of the flat roof 50 as shown in FIG. However, the uncured stock solution d may be injected after the pipe 2 is in this pushed state.

Next, as shown in FIG. 7, the stud bolt 1 is inserted into the pipe 2 and pushed down. When the uncured undiluted solution d pushed to the tip of the stud bolt 1 as shown in the figure expands the bag-like body 3 into a substantially spherical shape, the lower end of the stud bolt becomes the bag-like body. It is desirable that the bottom of 3 is not touched.

For this purpose, a method of attaching a mark (not shown) to the outer peripheral surface of the stud bolt 1 and aligning the mark with the upper surface of the lock nut 4 may be adopted. It is preferable that the filling amount of the uncured stock solution d is slightly larger than the bag-like body 3 is completely inflated.

After the above work is completed, if left for about 20 to 30 minutes to 1 to 2 hours depending on the temperature at the time of construction,
The uncured stock solution d is almost cured and becomes an epoxy resin.
The retaining member 5 is formed. In this state, when the locking nut 4 is screwed in, the locking member 5 serving as a bolt head and the locking nut 4 cooperate to sandwich the flat roof 50 as shown in FIG. It will be attached.

Thus, even a beginner of the work can reliably and firmly implant the stud bolt 1 on the flat roof 50.
It can be completed very easily and quickly. After the stud bolts 1 have been planted at all of the predetermined plural locations on the flat roof 50, a corrugated roofing material (fixed material) 52 is laid on the flat roof 50, so that the mounting studs 52 are attached. A plurality of channel members 53 serving as a base bone are fixed on a flat roof in a predetermined arrangement as shown in FIGS. The construction method of the roofing work is well known as is apparent in FIG.

FIG. 9 shows a second embodiment of the present invention. In this embodiment, a foam concrete slab (AL
C), an exterior wall material 70 for protecting the building, saving air conditioning costs, preventing dew condensation in the room, etc., is interposed with an insulating gap g having a predetermined thickness outside the wall body 60 of the building constructed using C). The present invention is applied to the work provided in a state where the work is performed.

The stud bolt 1 is planted in an insertion hole 61 formed in a wall body 60 in the same manner as in the first embodiment. In this case, since the pipe 2 is inserted not into the vertical direction but into the insertion hole 61 provided in the horizontal direction, a certain measure is required to fill the bag 3 with the uncured stock solution d.

For example, after a predetermined amount of uncured stock solution d is filled in a vertically oriented pipe 2, a filling such as a soft breathable sponge piece (not shown) is pushed into the upper surface of the pipe 2 to cover it. The pipe 2 may be inserted into the insertion hole 61 after the hardening solution d is prevented from flowing out of the bag 3. The sponge piece also helps to prevent the tip of the stud bolt 1 from breaking through the bag 3.

Alternatively, the flow of the uncured stock solution d is suppressed,
A putty made by blending a filler (filler) such as an inorganic powder for the purpose of increasing the strength and increasing the weight may be filled into the bag 3 using a caulking gun or the like. In this case, the lock nut 4 screwed to the tip of the pipe 2 can be omitted.

The role of the stud bolt 1 in this embodiment is as follows.
As shown in FIG. 9, a channel member (fixed member) 62 serving as a skeleton for attaching the exterior wall member 70 is fixed to the wall body 60. The exterior wall material 70 is attached to the channel material 62 by a known method.

In each of the above embodiments, the curable composition to be filled in the bag 3 is not limited to an epoxy resin. In short, the curable composition is filled in the bag 3 and the base 1a of the stud bolt 1 is inserted. At the stage of incorporation, it is necessary to provide a material having a necessary fluidity, but thereafter having a property of hardening as rapidly as possible and solidifying into a solid having a required mechanical strength. Therefore,
Elastomers such as silicone rubber and urethane rubber may be used.

[0028]

As apparent from the above description, according to the stud bolt planting structure of the present invention, the following excellent practical effects can be obtained. (A) Unlike a concrete nail or the like, even a concrete base having a relatively large thickness can be easily planted with necessary and sufficient pull-out resistance. (B) Therefore, if, for example, when a poorly-durable waterproofing agent layer applied to the upper surface of a flat roof deteriorates over time, a roofing material such as a corrugated sheet with excellent durability is applied on the roofing material, and the construction method may be adopted. Construction strength that can withstand a large typhoon can be obtained. (C) Even if the thickness of the base is different for each construction site, pipes of the required length are simply cut from long pipes to a fixed size.
Can be procured easily and quickly. (D) It can be easily and reliably planted even on a base with a thickness of several tens of centimeters. (E) The lock nut screwed onto the upper end of the pipe plays a role in preventing the pipe and stud bolt from falling, adjusting the lower end position of the pipe, and the like, and is extremely convenient in construction.
