JPH073041B2 - Composite flat plate with handle and manufacturing method thereof - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a handle composite flat plate (the handle is removed after construction) used as a flooring material for inside and outside buildings, housing exteriors, parks, streets, parking lots, etc. The present invention relates to a manufacturing method thereof.

<Prior art> Conventional flat floor materials inside and outside a building are, for example, large ones (vertical 30
cm, width 60 cm), but no handle.

<Problems to be solved by the invention> Therefore, in the conventional construction of the floor material inside and outside the building, since the joint width is narrow (for example, 3 mm) and the fingers cannot be inserted when finely adjusting after placing the flat plate, it is necessary to position it. was difficult. Due to this, there is a problem that the work time is increased along with the inaccuracy of the construction.

The present invention has been made in view of the above points, and an object thereof is to perform a construction work more safely and accurately and to shorten the time.

<Means for Solving the Problem> The problem solving means according to the present invention is, as shown in FIGS. 1 to 4, an upper rectangular (variable in various shapes such as I type and H type) decorative plate 1,
A lower concrete plate 6 integrally formed with the decorative plate 1 and a handle band 2 attached to the upper side of the decorative plate 1.
It is composed of and.

<Operation> The construction of the composite flat plate with the handle of the above problem solving means will be described with reference to FIGS. 4 and 7. First, the buffer case 3 is broken, the handle band 2 is grasped by hand, carried to a predetermined place, and sequentially arranged and adjusted. Fix it. After that, the handle band 2 is cut right next to the decorative plate 1 at a position flush with the decorative plate 1 by using a cutter C or the like, and then the joints are filled with sand to complete.

<Example> A first example of the flat plate of the present invention will be described below with reference to Figs. First, the composite flat plate A with a handle will be described. As shown in FIG. 4, this is an upper rectangular (variable of various shapes such as I type and H type) decorative plate (made of artificial stone or the like) 1 and
A lower concrete plate 6 integrally formed with the decorative plate 1 and a handle band 2 attached to the upper side of the decorative plate 1.
It consists of and.

The entire surface and the entire side surface of the handle-equipped composite flat plate A are covered with a cushioning case (made of expanded polystyrene).

Next, a method of manufacturing the composite flat plate with a handle will be described. This is as shown in FIG.
2a are brought into close contact with each other, then the decorative plate 1 is installed in the buffer case 3 with its front side facing down, and the four side surfaces 3a of the buffer case 3 are brought close to the steel form 4 as shown in FIG. Then, this is tightened by an appropriate means, and then the adhesive 5 is applied to the back side of the decorative plate 1, and concrete 6a is placed on the decorative plate 1 and the root portion 2b of the handle band 2 in the state shown in FIG. After the curing, the mold 4 is loosened and removed to obtain a composite flat plate A with a handle (FIG. 4) with a buffer case 3.

The handle band 2 of the present invention has a thickness of 0.2 mm and a width of 50 mm, for example.
The yield strength is 180 kg / piece.

The flat plate A is, for example, 30 cm in length, 60 cm in width, and 6 cm in thickness.

The construction of the composite flat plate with a handle of the present invention will be described with reference to FIGS. 4 and 7. First, the buffer case 3 is broken and the handle band 2
Grasp them by hand, carry them to a predetermined place, arrange them in order, and fix them. After that, the handle band 2 is cut right next to the decorative plate 1 at a position flush with the decorative plate 1 by using a cutter C or the like, and then the joints are filled with sand to complete.

Further, as another cutting method, particularly when the thickness of the handle band 2 is large, the handle band 2 can be cut at the root portion 2b protruding from the concrete plate 6.

Further, regarding the mold 4 at the time of manufacturing the flat plate of the present invention, the example of FIG. 6 will be explained. As shown in FIG. 1, the main body 2a of the handle band 2 is laid on the two decorative plates 1 and the buffer case 3 is used. After putting them in the enclosed state, these two are installed on the left and right sides of the T-shaped fixed formwork 4a, and the left and right L-shaped formwork 4b and the inverted L-shaped formwork 4c are set around two fulcrum screws 7a, 7b. The decorative plate 1 is rotated so as to be narrowed, and the fastener 8 on the L-shaped mold 4b is hooked on the fastener 8 on the L-shaped mold 4b to lock it. After that, the adhesive 5 is applied and the fresh concrete 6a is poured.

Furthermore, the four side surfaces 3a of the soft buffer case 3 in the manufacturing process are
As shown in FIG. 5, by tightening the formwork 4, all the side surfaces 1a of the decorative plate 1 and the rising portions 2c of the handle band 2 are sealed (the case is slightly recessed because it is soft), and the backing concrete 6a is the decorative plate 1. Prevents dirt from getting on the surface. In addition, the buffer case 3 protects the decorative plate 1 and the handle band 2 as a buffer material during product transportation.

Further, FIGS. 8, 9 and 10 are second, third and fourth embodiments of the flat plate A of the present invention, and the configurations and operations other than the flat plate shape and the number of handle bands 2 are the same as those of the first embodiment. .

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

<Effects of the Invention> As is clear from the above description, in a general flat plate construction, the construction joint width is narrow and fingers cannot be inserted, and it is difficult to position it during installation, but in the present invention, the handle plate is attached to the composite flat plate. Thus, the handle band can be grasped and moved by hand to easily perform positioning and correction during product installation and construction.
Further, since the handle band can be easily cut off after construction using a cutter or the like, it does not spoil the appearance.

Furthermore, in the manufacturing process, the four sides of the soft cushioning case seal the entire side of the decorative plate and the rising part of the handle band by tightening the formwork (the case is slightly recessed because it is soft). Prevents dirt from getting around.

Further, the buffer case protects the decorative plate 1 and the handle band as a buffer material during product transportation, and the present invention has an excellent effect.
