Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a technology for creating a wall surface by horizontally connecting concrete unit plates, and for pouring ready-mixed concrete on the back side of the wall surface to form a wall surface or a wall surface of a building. Related to technology for constructing retaining walls, etc. and concrete unit plates used therein (prior technology) Conventional techniques for constructing retaining walls on vertical or sloped surfaces of buildings include: Conventionally, construction was carried out by using concrete blocks with a hollow part, inserting reinforcing bars into the hollow part, and then filling the remaining space in the hollow part with mortar. The reinforcing bars are thin,
Because the gap was too large, in order to maintain the flatness of the adjacent concrete blocks, it was necessary to make corrections while checking the linearity by adjusting the water system, etc.

In addition, as a technical idea somewhat similar to the present invention, in order to connect adjacent templates for concrete construction, hooks are provided in advance at important points on each template, and hooks are provided in advance to connect adjacent templates. The technical concept of inserting a connecting rod into the hook of the template has already been published in Japanese Patent Application Laid-open No. 123945 and No. 58.
-123946, JP-A-58-127837, etc.

(Problems with the prior art) All of the above technical ideas require a gap between the hook or cavity and the connecting rod, and therefore the flatness of adjacent plates must be corrected by other means such as a water system. Things that must not happen. In particular, the latter relates to templates; if a concrete block similar to this template is made, its weight will be large, so it is necessary to hold and support the concrete block in a predetermined position. There was a disadvantage in that several workers had to work together, including several workers holding the concrete blocks and a worker inserting the connecting rods into the hooks of these concrete blocks.

(Means and effects for solving the problem) In order to solve the above problem, the present invention has a structure of a concrete unit plate in which the nail or screw receiver has a hole and the connecting plate is embedded in advance in contact with the back surface of the block. , and using this unit plate, the connecting plate is attached to each adjacent concrete unit plate by using a member to bridge and connect the connecting plates, and the construction is carried out by pouring concrete on the back side of the connected concrete unit plate. Methods of constructing walls of objects or retaining walls, and other methods of construction or buildings using the concrete unit boards, in which adjacent blocks can be easily made into accurate planes, construction work can be easily done by one person, and the construction of adjacent blocks This has the advantage that there is no need for joints because the blocks are firmly connected to each other (Embodiments) The present invention will be explained in detail below with reference to embodiments shown in the drawings.

Fig. 1 is a slope view showing the state of Uniso Nippon Steel before concrete pouring for constructing walls with concrete unit boards for buildings according to the present invention. A member 3 for attaching a connecting plate having a hole for a nail or screw receiver is embedded in advance in key points of the concrete unit plate 2 to be built on top of the concrete unit plate 2, and the member 3 is used to attach the connecting plate and the connecting plate 4 is used to adjoin the connecting plate. The concrete unit plates are bridged and connected to each other, and ready-mixed concrete is poured between them and a separately established template 5 to form the wall surface of the building. Incidentally, as shown in FIG. 1 4', the work can be carried out even more easily if the foundation 1 and the concrete unit plate are also connected by a connecting plate.

2nd-(Figure 81 is a plan view of an example of the connecting plate mounting member used in the present invention, 2nd-(b1 is a side cross-sectional end view thereof,
FIG. 3 is a side sectional end view of the holding lid 14 of this member, and for mounting the connecting plate, the member 3 is provided with holes 6 and 6' for nail receivers and holes 7 for screw receivers.

However, it is not necessary to provide both holes 6 and 6' for the nail receiver and hole 7 for the screw receiver as in the example, but it is sufficient to provide either one depending on the lateral pressure of the fresh concrete to be poured later. .

FIG. 3 is a side cross-sectional end view of the presser cover 14 used in this embodiment, and the connecting plate is attached to the screw receiver of the member 3 through the bolt portion 1) screwed into the hole 7 and the nail hole 6.6. A nail hole 8.8' is provided for passing a nail through.

Of course, it is sufficient to provide either the bolt part 1) or the nail hole 8, as described above for the connecting plate 3.

As mentioned above, when attaching the connecting plate, which has holes 7 for screw receivers and holes 6 and 6' for nail receivers, attach the member 3 to the concrete unit so that both holes 7° and 6 are in contact with the back surface of the concrete unit plate 2. When manufacturing the board 2, it is manufactured by embedding it in the concrete unit board in advance.

FIG. 4 is a back view of this concrete unit plate.

In addition, in the case of the concrete unit board whose slope view is shown in Figure 1, the surface is a fractured surface, that is, after the concrete unit board has matured, the surface is fractured to create an uneven surface similar to natural stone. The figure shows something that gives a sense of weight to objects, etc., and since the connecting plate is attached to the back side of the concrete unit plate 2 without appearing on the surface, when the wall surface is completed by pouring fresh concrete, , which is buried in concrete, and there is no need to remove the connecting plate 4 and the member 3 for attaching the connecting plate after the wall surface is completed.

Similarly, the surface of the concrete unit plate is not limited to the breaking process, but the present invention can also be carried out by performing conventional concrete surface decorative processes such as cutting, bisect processing, or polishing process.

Figure 4 is a plan view of the connecting plate, also with nail holes 9.9'
and a through hole lO of the bolt part 1) of the presser cover 14 are provided, and the presser cover is fixed and connected by the bolt part 1) of the presser cover and a nail (not shown). Since it is only necessary to use one of the nails and the nail, it is sufficient to provide only one hole in the connecting plate. This is the same as described in the explanation of the members for attaching the connecting plate.

As shown in FIG. 1, the concrete unit plate of the present invention is placed on a foundation 1, bridged between the adjacent concrete unit plates 2, a connecting plate 4 is applied, and a presser cover 14 is applied. Therefore, press M14. Connecting plate 4
．． To attach the connecting plate, match the nail holes 8, 9.6 of the member 3 and connect the connecting plates with nails (not shown), or connect the bolt part 1) of the retainer M14. When attaching the connecting plate through the bolt hole 10 of the plate, the screw receiver of the member is screwed into the hole 7, thereby connecting adjacent concrete unit plates by bridging them with the connecting plate.

In addition, the concrete unit F connected by the connecting plate 4
A gap corresponding to the wall thickness is maintained between i2 and the template 5 by a separator 12, which will be described later. Therefore, on the concrete unit plate 2, the same members as the connecting plate attachment 1 member 3 are installed at important points of the concrete unit plate 2 (in the embodiment, the central part shown in FIG. 1 3'), and the template is 5 is similarly attached by providing a member and holding the separator 12 by screwing bolts on both sides of the separator 12, which will be described later, into the screw holes 7 of this member described in FIG. In this embodiment, the template 5 is removed in the same way as a normal template after the cast fresh concrete has matured.

Of course, although the drawings are omitted, it goes without saying that if reinforcing bars are required, they should be placed in advance, as in conventional concrete wall construction.

FIG. 6 is a side view showing a state in which the template is held by curing in the same manner as in the prior art, except that one end of the separator 12 is attached to the screw receiver through the hole 7. Of course, the present invention may also be implemented in this manner. Needless to say, it's a good thing.

FIG. 7 is a drawing similar to FIG. 6 in which another concrete plate 5' is used instead of the template shown in FIG. 1 or FIG.
' is adjusted by the separator 12.

Although not shown, the separator 12 is provided with a bolt part having the same shape as the bolt part 1) of the holding lid on both sides, and the center part is divided into two parts, and a screw adjuster 12 is provided on both sides of the separator 12.
The structure is such that the thickness can be adjusted by .

In the embodiment shown in the figure, one wall surface is a concrete unit plate 2, and the other surface is also a concrete unit plate 5'.
A reinforced concrete wall will be formed between the two.

FIG. 8 is a conceptual side view showing the state in which the present invention is used in a retaining wall block, and shows that the concrete unit plate of the present invention and the construction method of the present invention can be implemented as a retaining wall for retaining earth 13. Then, another concrete plate 5' is placed on the slope of the ground 13, or the concrete unit plate of the present invention is placed adjacent to the concrete piled up as a waste concrete in this area via the separator 12 in the same manner as described above. They are constructed by connecting them with connecting plates and pouring ready-mixed concrete into the gap between them.

Finally, in the present invention, to explain the materials of each member used, each member can be selected from materials such as iron, non-ferrous metals, and plastics that have the strength to withstand the lateral pressure during concrete pouring. If you use materials that do not rust, such as plastic, a fence with a structure where these parts are exposed on the back side will last a long time.

(Another Embodiment) Of course, it goes without saying that the present invention is not limited to the above-mentioned embodiment. , I have already mentioned that it is advisable to provide one or the other depending on the need. Also, the holes for installing the separator may be omitted if they are not necessary.

Further, the concrete unit board in which the present invention can be implemented may be used to construct a structure such as a single-layer concrete block wall. In that case, it is desirable to use appropriate joints and to use a connecting plate made of a rust-resistant material such as stainless steel or plastic plate. Alternatively, the joint may be coated with mortar without such treatment.

Furthermore, if a surface decorative material such as tile, brick, natural stone, etc. is attached in advance to the surface of the concrete unit board of the present invention at the manufacturing stage of the concrete unit board,
By pouring ready-mixed concrete, a tiled or bricked building can be immediately completed, and the labor required for layering can be saved and a beautiful building can be obtained.

(Effects) As described above, in the present invention, first, adjacent concrete unit plates are fixed to each other using nails or screws using a connecting plate, so it is easy to connect adjacent unit plates horizontally and completely flatly. Unlike conventional methods such as connecting concrete blocks using hooks, there is little need to modify the flatness due to water systems, etc.

Furthermore, for the above reasons, concrete unit plates can be assembled one by one, so it can be assembled by one person without the cooperation of several workers during construction work, which is efficient and requires the use of cranes, etc. It can be constructed without using large-scale construction machinery.

As in the embodiment, a member that also serves as a part can be used to attach the separator, so material management can be omitted.

Adjacent concrete unit plates are connected by connecting plates, so joints are not necessarily required in construction.

Since the connection between adjacent concrete unit plates is strong, if it is used in the concrete block wall described in the previous example, it will not be possible to solve the problem of concrete block walls, which has recently become a problem.
Block walls can be designed and constructed with less risk of collapse due to earthquakes.

In addition, generally, for concrete buildings, after the shape of the building is formed using templates, fresh concrete is poured between the templates, and after the concrete has matured, the templates are removed.
Furthermore, the process of applying a topcoat is necessary, which means that it takes twice as much time and effort, but with the concrete unit board that can carry out the present invention, the process of assembling it is as simple as described above. Since it requires the same amount of time and effort as constructing templates for concrete construction, it is possible to construct a building with concrete unit plates arranged on the surface with the same amount of time and effort as it takes to pour concrete in concrete construction.

In general, buildings with concrete unit boards placed on the surface are more beautiful than buildings with exposed concrete surfaces, but if the present invention is implemented, buildings with concrete unit boards placed on the surface can be built with the same effort as building with exposed concrete. This means that things can be built. Moreover, if the surface of the concrete unit board of the present invention is made of a decorative block such as a broken block, or a concrete unit board covered with tiles or bricks, as in the above embodiment, - a layered and beautiful concrete unit can be created. Since board buildings can be built with the same amount of time and effort required for pouring concrete in regular concrete buildings, it is expected to be very useful.

Furthermore, if tiles are pasted on the surface of the unit board of the present invention in advance at the stage of manufacturing the concrete unit board as described above, a building with tiled walls can be completed immediately by pouring fresh concrete.
