Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention attaches a finishing material to a ceiling wall of a concrete structure at the time of assembling a ceiling formwork, and at the same time as forming a ceiling by driving concrete, the ceiling finishing wall is completed. Method for constructing ceiling wall of concrete structure.

(Prior art) When the structure ceiling of a factory or office is made of concrete structure, conventionally, it is exposed concrete, or plaster or plaster is applied to the surface of the ceiling, or slabs are used to tie down fishing rods or hanging bolts. There is a suspended ceiling with boards attached to it.

(Problems to be solved by the invention) In this conventional exposed concrete ceiling, the influence of humidity and the like is great, and honey is accumulated and drops are dropped to damage the product,
There is a problem that the reflected sound is large and causes noise.
Also, in the case of plaster or plaster on the ceiling surface or the suspended ceiling type, it is necessary to perform these operations after removing the ceiling formwork, and the number of processes increases, and in the case of the suspended ceiling type in advance It is necessary to embed a large number of embedding bolts and inserts when assembling the form, and there is a problem that it takes a lot of time and effort to adjust the ceiling construction date.

In addition, the floor height of the skeleton is high, and the number of days and personnel required for the construction are additionally required, which causes a problem of cost increase.

(Means for Solving Problems) The present invention has been made to solve the above conventional problems, and it is possible to easily attach a finishing material to a ceiling wall of a concrete structure at the time of assembling the formwork. In addition, the present invention provides a method for constructing a ceiling wall of a concrete structure, in which the ceiling finishing wall is completed at the same time when the ceiling is formed by pouring concrete, and the cost can be reduced.

The gist of the idea is to form a long fixture that holds a peripheral edge of a ceiling finishing material and holds a ceiling surface of a ceiling formwork, a locking portion that prevents the ceiling from falling off, and a groove. Temporary fixing material is attached to the upper surface of the formwork in a layout of the ceiling wall, the groove is inserted into the temporary fixing material, the lower surface of the holding portion is brought into face-to-face with the upper surface of the ceiling formwork, and the fixture is temporarily fixed. After placing the ceiling finishing material on the holding part of the fixture, concrete is placed on the upper surface of the ceiling formwork to embed the fixture and ceiling finishing material together, then the ceiling formwork is disassembled and the ceiling finishing material is removed at the holding part. A method of constructing a ceiling wall of a concrete structure, characterized in that the ceiling wall is constructed in a state of being adhered to the lower surface of the ceiling, and the fitting portion is prevented from falling off by a locking portion embedded in concrete.

(Operation) The ceiling wall of the present invention has a structure in which the ceiling finishing material is adhered to the concrete surface with the fixture.

When the ceiling formwork is assembled, the fixtures are temporarily fixed to the upper surface of the ceiling formwork at appropriate intervals.

First, from the characteristics and design of the ceiling finishing material, the spacing, the overall size, etc. are determined, and the temporary fixing material is allocated and fixed on the ceiling formwork upper surface. Then, after inserting the groove portion of the fixture into the temporary fixing material, it is temporarily fixed to the ceiling formwork with a nail or the like. At this time, since the holding part of the fixture is in a state of facing the upper surface of the ceiling formwork, if a ceiling finishing material is placed on the upper part of this holding part, the parts other than the holding part will face the upper surface of the ceiling formwork. It will be in the state of doing. After placing the ceiling finishing material on all of the fixtures, place concrete. In the ceiling formwork, the ceiling finishing material, the fixture and the locking part of the fixture are both embedded in concrete, but the ceiling finishing material faces the ceiling formwork and is sandwiched because it is in a mounted state. There is nothing to do.

Remove the ceiling formwork after appropriate time. The lower surface of the ceiling finishing material and the holding portion of the fixture was exposed to the lower surface of the slab because it was in contact with the ceiling formwork. Further, since the locking portion of the fixture is embedded in concrete, it does not fall off, so that the ceiling finishing material placed on the holding portion also does not fall off.

(Example) Hereinafter, the Example of this invention is described based on drawing.

In this embodiment, the overall shape of the ceiling wall (16) is rectangular and the inside is allocated in a small rectangular shape.

Fig. 1 shows the cross section of the peripheral edge and the internal allocation part. In the figure, (1) is a peripheral edge fitting, (2) is an allocation fitting, and (3) is a substantially T-shaped member. Stop part, (4) flat holding part, (5) ceiling finishing material with sound absorbing effect, (6) ceiling, (7)
Is the lower surface of the ceiling finishing material, and (8) is the lower surface of the ceiling. Both the peripheral edge fitting (1) and the layout fitting (2) are made of aluminum, and a groove (9) is provided below.

Figures 2 to 3 show the cross-section during construction. (10)
Is a joint bar with a sloping side for the turning edge, and (11) is a one-letter type fixing tool used as a temporary fixing material.

The cross part (12) of the mounting fixture (2) uses a cross-shaped fixture (13) as shown in FIG.

Fig. 4 shows the assembly sequence, including the allocation of the ceiling construction surface. The joint bar (10) forms the peripheral edge, and the one-piece fixture (11) is formed.
At the same time, the cross-shaped fixtures (13) are nailed to the ceiling formwork (14) at the same time. Also, the cross section (12)
Cut the mounting fixture (2) for
Each is temporarily fixed with a nail (15).

Incidentally, (17) is a ceiling formwork upper surface, and (18) is a holding portion lower surface.

In this embodiment, since the ceiling finishing material (5) having a sound absorbing effect is used, the same effect as that of attaching a sound absorbing material to the ceiling can be obtained, and the ceiling does not become low. Moreover, since it can be installed at the same time as the ceiling is formed, the construction period can be shortened and the cost can be reduced.

A decorative plate or the like may be fitted in the groove (9).

Although the embodiment of the present invention has been described above, the specific configuration of the present invention is not limited to this embodiment.

For example, the shape and the like of the fixture are not limited to those shown in the drawings, and the cross-sectional shape and the like can be arbitrarily selected. Further, as the material, steel, plastic or the like can be used.

Also, in the construction, for example, the ceiling is laid out in a rectangular shape, but the laid-out shape or the like can be arbitrarily determined such as a polygonal shape.

Further, as the ceiling forming material, a humidity control material can be used.

(Effects of the Invention) According to the present invention as described above, since the ceiling finishing material is attached by the fixture when the ceiling formwork is assembled, the ceiling wall is formed at the same time when the ceiling is formed by driving concrete. You can Further, since the ceiling wall is attached to the ceiling, the floor height of the skeleton can be lowered, the construction period can be shortened, and the construction cost can be reduced.

In addition, the lower surface of the holding portion of the fixture is exposed, which serves as an accent and has an effect of giving a beautiful appearance.

Also, sound absorption and humidity control effects can be measured by selecting a ceiling finishing material.
