DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ready-made shelter member used as a rooftop parapet shelter, a waterproof standing waist wall, etc., and a method of constructing a rooftop parapet shed using the shed member. .

[0002]

2. Description of the Related Art It is not an exaggeration to say that concrete framing to be fitted with a waterproofing part on a roof is almost constructed by a plywood formwork method. After the wall is cast, a plywood form is assembled on the side of the wall to separate and cast concrete at the skirting jaw portion, or a highly skilled form carpenter is put in, as shown in FIG.
As shown in (1), the formwork of the wall and the jaw-portion are assembled together, and concrete is cast at the same time.

[0003]

In any case, the construction of the bonnet is a special part and is a bottleneck in the process. In general, the construction of the concrete frame on the roof tends to be delayed, so it is waterproof. There is a problem that it is easy to affect the next process such as construction and tower outdoor wall construction, and there is a concern about quality due to the recent lack of skilled technicians.

The present invention has been conceived in order to solve the above-mentioned conventional problems. An object of the present invention is to convert a kasagi into a member which can be produced in a factory and to make the member as it is into a wall concrete frame. A new structure that can be attached to complete the cap, and the use of the cap is used to construct rooftop parapet caps and external waist wall waterproof rising tori caps without the need for a complicated formwork assembly process. It is to provide a new construction method that can be used.

[0005]

SUMMARY OF THE INVENTION The above-mentioned object of the present invention is characterized in that the required length of the cement-based composition is basically square, the cross section is inclined, the upper surface is inclined, and the hollow end is open. In this case, a lateral groove for bolt insertion is provided in the longitudinal direction on the back surface of the main body, and joints are provided in the longitudinal direction on the front side of the lower surface.

[0006] A feature of the construction method of the roof parapet shed or the like according to the present invention is that a mounting lateral groove for accommodating the back surface of the above-mentioned shed member and a required number of bolt holes opened at regular intervals in the mounting lateral groove are formed by a wall concrete frame. Formed at the time of casting
After completion of the wall concrete skeleton, the backing member is brought into contact with the mounting lateral groove on the back surface, fixed to the wall concrete skeleton by a fastening bolt, and caulking joints and the like.

[0007]

With the above-described construction, the fastening bolt can be projected from the back surface with the lateral groove on the back surface, and the bolt can be positioned by freely moving the lateral groove horizontally. In addition, no formwork is required during construction, and the bolts can be securely fixed to the wall concrete frame, and the completed Kasagi is maintained for a long time by fastening bolts.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 to 4, reference numeral 1 denotes a ready-made main body having a required length to be a coping member, which is formed of a cement-based composition such as concrete or high-strength cement mortar. The cross-sectional shape of the main body 1 is basically rectangular, and the upper surface 11 is low and slightly inclined toward the front surface 12. The main body 1 is a hollow body having both ends opened to make the inner shape the same as the outer shape.
The rear surface 13 has a lateral groove 14 for bolt insertion in the longitudinal direction,
On the front side of the lower surface 15, a joint 16 for draining and a joint 17 for a protection panel are provided in parallel in the longitudinal direction.

Such a main body 1, that is, a coping member can be formed in a factory using an inner mold and an outer mold. When a metal plate is used as the inner formwork, the inner formwork is left as a cover plate 18 on the inner wall surface and the lateral groove wall surface as shown in FIG. Can be prevented.

In order to construct a cover on the inner surface of the wall concrete skeleton 2 of the rooftop parapet using the above-mentioned cover material, first, a mounting lateral groove 21 in which the rear surface 13 of the main body 1 is accommodated in the wall concrete framing 2, and the mounting lateral groove. A required number of bolt holes 22 that are opened at regular intervals are formed at the time of casting.

As shown in FIG. 1, the mounting lateral groove 21
It is a shallow groove in which an appropriate cover is formed on the capping member, and has a vertical width enough to allow the main body 1 to be easily accommodated in the vertical direction. Further, a portion where the bolt hole 22 is opened outside the wall concrete frame 2 is formed in a nut mounting recess 23.

After completion of the wall concrete frame 2,
Before attaching the skirting member, a required number of fastening bolts 3 are protrudingly provided on the back surface 13 of the skirting member before that.
This projecting can be easily performed by inserting the head side of the binding bolt 3 from the end opening into the lateral groove 14 and housing the head 31 together with the washer 32 in the coping member. In addition, since the shaft portion of each binding bolt 3 can freely move horizontally in the horizontal groove 14, the positioning with the bolt hole 22 on the wall concrete skeleton side can be easily performed.

When the fastening bolt 3 is protruded at an approximate position, the back surface 13 of the coping member is brought into contact with the mounting lateral groove 21 while inserting the fastening bolt 3 into the bolt hole 22. As a result, the tip of the binding bolt 3 projects into the recess 23 outside the wall concrete frame 2, and the nut 33 is screwed onto the tip to tighten the bolt. As a result, the cap member is attracted to the wall surface in the mounting lateral groove and is completely fixed.

After the required number of coping members have been mounted as described above, caulking 34 is applied to the recesses formed on the main body 1 above the mounting lateral grooves 21 and the gaps between the coping members. As a result, the seam is sealed in a water-tight manner, and a coping secured by bolts is completed.

The above embodiment is an example of the construction of a rooftop parapet shelter, but it is also possible to construct a waterproof rising waddle with an external waist wall by similar means. In this case, no formwork is required at all.

[0016]

As described above, according to the present invention, a roof member is constructed by using a pre-formed member as a main body, and the roof member is bolted to a wall concrete frame by a fastening bolt projecting from the roof member. The following effects can be obtained because the parapet canopy can be completed.

[0017] Since the coping material can be produced at the factory, quality control is well-controlled, and since the fastening bolts can be inserted into the lateral grooves and protruded from the back, it takes time to project and position the fastening bolts. I can't take it.

From the improvement of molding accuracy by factory production,
A joint for draining and a joint for receiving a waterproof protection plate can be reliably constructed, and a highly reliable waterproofing treatment can be obtained.

The complicated mold assembling process becomes unnecessary,
In addition, since no skill is required for construction, labor can be saved, the construction period can be shortened, and costs can be reduced.

Since no formwork such as Lauan plywood is used during the construction of the sash, it contributes to a reduction in the use of plywood formwork and can contribute to the conservation of forest resources.
