Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cloth foundation block used for houses such as general houses, prefabricated warehouses and temporary houses.

[0002]

[Technical background]

 Conventionally, the foundation for houses has been constructed by cutting the construction site, laying cobblestone, placing a stencil, framing a formwork panel on it, and pouring a fresh concrete into it. It goes through a series of steps of leaving for days to wait for curing and removing the formwork. However, this conventional method has the following drawbacks. (A) It requires a laborious work in the field to pour raw concrete from the framework of the panel, which causes a delay in construction due to lack of manpower, and is the target for the most labor saving. (B) When the concrete is poured into the frame, it tends to contain a large amount of water in order to maintain the fluidity, and there is a physical drawback that the concrete strength is insufficient after curing.

[0003]

[Prior art]

 In response to these, the following techniques have been conventionally proposed. (A) A cloth foundation (Japanese Utility Model Laid-Open No. 62-35045) in which one end of the vertical wall portion of the cloth foundation main body is arranged in a projecting position more than the one end of the horizontal wall portion and they are adjacent to each other by combining them. (B) A concrete block having a fixed length and an inverted T-shaped cross section, which is a combination of a cloth foundation and a base, and which forms a joint portion at the central body and both ends thereof, and the joint portion has a thickness A cloth foundation block (Japanese Patent Laid-Open No. 61-162636) in which the central portion and the lower portion of the base are made into a continuous space, and the reinforcing bars project into the space from the main body side.

[0004]

However, in the above technique, in the case of (a), the protrusion can be used to join in a key shape, and physical strength that is strong against vibration and the like can be exhibited. Since only the end of the reinforcing bar is exposed at the retracted position, the connection between adjacent blocks is weak and there is a surface that lacks integrated strength as a cloth foundation. In addition, in (b), the strength of the joint surface can be maintained, but there is a lack of a structure such as a key combination, and only the strength of the poured mortar is relied upon, which is still insufficient for exerting the overall strength. Have The present invention has been made based on the above-mentioned circumstances, and is premised on the development of a cloth foundation that can be quickly and easily constructed at the construction site, and the overall strength as the foundation material can be exhibited, and at the same time, cracks and the like generated at that time can be exhibited. It tries to solve the problem.

[0005]

[Means for Solving the Problems]

 The building foundation block for construction of the present invention is composed of a base portion and a pillar portion having a side-reverse T-shape, and the left and right sides of the pillar portion are divided from substantially the center in the longitudinal direction and one of them is extended to the outside of the base portion. Column protrusions are formed on the opposite sides, respectively, and an inclined joint slope is formed between the base and the column, and a joint notch that fits the joint slope is formed on the bottom side of the column protrusion. , A relatively shallow mortar filling recess is formed between the end face of the column and the joint slope, and a deep column pit is formed on the column protrusion, and the reinforcing rods of different diameter are formed inside the filling pit and the column pit. The base protrusion of the base block adjacent to the base protrusion of the base block, and the base rest of the block adjacent to the base protrusion on the side opposite to the base protrusion, are fitted into the concave and convex portions, respectively, and the filling recesses of each other are filled. It is configured by filling mortar with mortar and connecting them to each other.

[0006]

[Action]

 When one base block is placed at a predetermined position and then adjacent base blocks are connected in series, the base projecting portion and the column projecting portion of the adjacent block face each other, and the filling recess is formed between them by the column gouging portion. In addition, since the base backing part and the base protruding part of the adjacent block on the opposite side are joined and combined with each other in a concave and convex key shape to be fitted, the connection is strengthened. At that time, when vibration such as an earthquake is applied, the joint slope disperses the load applied vertically to the lateral force according to the hypotenuse, and cracks etc. occur at the joint surface between the base and column. Prevent. In addition, when the filling recess is filled with mortar, a bonding layer is formed with protruding deformed reinforcing bars on both left and right ends, and the bonding and solidifying forces integrate the entire structure, and the reinforcing bars act to prevent the occurrence of earthquakes and other physical damage. Demonstrate strength. Furthermore, the pillar-cutting part itself does not form a deep groove, so that it is easy to remove the mold during manufacturing.

[0007]

【Example】

 An embodiment will be described below with reference to the drawings. The cloth foundation block of the present invention is roughly divided into a base portion 10 and a column portion 20, and the straight portion of FIG. 1 and the corner corners of FIGS. There are aspects such as a-part and a flat T-shaped joint, but in the present embodiment, the most frequently used straight part will be described as an example.

As shown in FIG. 3, the base portion 10 is combined with the pillar portion 20 so as to form an inverted T-shape on the side surface, and as shown in FIG. 1, one is used as the base protruding portion 11 and the other is used as the base support. It is formed in the part 12.

Then, the joint slope 13 for enduring the vibration of an earthquake or the like and preventing cracks is formed at an angle of, for example, 5 ° to 15 ° between the base protruding portion 11 and a vertical end surface of a pillar portion 20 described later. Form with an inclination. The joint slopes 13 are for increasing the strength of the block body and for facilitating the assembly at the time of jointing with the adjacent block. 22a and 22b are received by the joint slope surface 13 so that the load against vibration and shaking can be dispersed.

Further, a relatively shallow mortar filling recess 14 is formed between the end face of the post-cutting portion 21b and the joint slope 13, which will be described later. Furthermore, in order to provide stability in the front-rear direction, the side extension parts on both sides are formed. Also, filling recesses 15 and 16 are provided, and deformed rebars 15a and 16a are projectingly provided inside.

On the other hand, the base backing portion 12 forms a key portion that engages with the adjacent base protruding portion in a concavo-convex shape at the time of connection, and corresponds to the joint inclined surface 13 on the base protruding portion 11 and the joint inclined surface 13 and The joint notch 24 is formed with an equal inclination angle. Then, deformed rebars 12a ... Are provided inside so as to correspond to the positions which become the filling recesses of the base projecting portions of the adjacent blocks.

Next, a column portion 20 is integrally formed on the base portion 10. The column portion 20 is divided from the substantially central portion in the longitudinal direction and extends from the base portion 22a. A column projecting portion 22b on the opposite side is formed, and column hollow portions 21a and 21b are formed in a pair on the opposite side. The pillar protrusions are divided into 22a and 22b because the filling recesses formed by the pillar hollow portions 21a and 21b when adjacent blocks are combined are formed in one block. This is to prevent the groove from becoming deep and difficult to demold. A plurality of deformed reinforcing bars 23a, 23b are vertically arranged side by side in the column cutting portions 21a, 21b at positions corresponding to the protruding columns of the adjacent blocks, and are vertically arranged with the deformed reinforcing bars 14a of the base portion 10. Arrangement is performed so that mortar is filled and hardened in the filling concave portions formed by the pillar hollow portions 21a and 21b between the adjacent blocks so that the bonding layer can be formed. Then, in order to increase the strength of the bonding layer, it is branched into two forks, and the connecting metal fittings 30a and 30b for vertically sandwiching the reinforcing bars are provided to connect the reinforcing bars in the vertical direction.

The filling concave portions 14, 15 and 16 gradually open the concave portion inlet portion to a wide mouth to bring the layer of the filling mortar closer to the outer wall surface and deepen the bond. In addition, the bottom surface of the column protrusion 22a is a surface that is joined to the base protrusion 11 as described above, and is formed in the joint cutout portion 24 at an inclination angle equal to that of the joint slope 13.

Further, joining grooves 31a, 31b, 31c, 31d, 31e for temporary fixing to adjacent blocks are formed on a part of the side surfaces of the base portion 10 and the pillar portion 20, and the iron plate 32a is formed therein. , Anchor bolts are projected so that 32b ... Can be bolted. Incidentally, 34 is an anchor bolt for continuously arranging a building base on the pillar portion 10.

Further, it is desirable to embed a molded body 25 of a foamed resin such as foamed styrene in order to allow a pipe for water supply and drainage to penetrate through a part of the pillar portion. As shown in FIG. 7, the shape of the molded body 25 is a ball shape of a substantially abacus with the conical shapes back-to-back, and if the outer concrete portion is slightly broken when piped later. The molded body is exposed, and the molded body made of foamed resin is hollowed out to form a through hole.

Next, the construction method and operation of the fabric base block will be described. First, in constructing the block of the present invention, a stacon is laid on a construction site such as a house to flatten the laying surface of the foundation. It is the same as the conventional method. Then, the factory-produced block is transported to the site, some mortar is laid on the above-mentioned Stecon, and the foundation block is laid while leveling with a level. Then, the normal block is provided in the straight line portion, the corner block is provided in the right-angled corner, and the T-shaped block is provided in the branching portion so as to correspond to each other (see FIGS. 5 and 6). At that time, when one block is laid, the pillar protrusion 22a of the adjacent block is overlapped on the base protrusion 11 of the one block, and the base protrusion 11 of the adjacent block is joined to the base backing portion 12 on the opposite side. In this case, the column protrusions 22a and the column protrusions 22b of the adjacent blocks are opposed to each other at this time, and the column hollow portions 21a and 21b form a filling recess. Then, the one basic block and the adjacent block are combined with each other in the concave-convex fitting, resulting in a physically strong combination that can withstand an earthquake or the like (see FIGS. 2, 3, and 4).

Next, the deformed reinforcing bars of the adjacent blocks project from the facing side in the filling concave portion formed by the column hollow portions 21a and 21b and are arranged in a line in the vertical direction with respect to each other, so that the vertical coupling metal fittings 30a, 30b are provided there. It hangs so that it hangs one by one.

Then, mortar is filled in the filling concave portions formed by the column hollow portions 21a and 21b of the column protruding portion 22b adjacent to the column protruding portion 22a and the filling concave portions 15 and 16 of the base side extending portion, and 2-3 The curing is promoted for about a day to form a bonding layer. This mortar can shorten the construction period by using cement for quick setting when the construction is urgent.

Then, a bonding layer is formed between adjacent blocks through the filling recesses in the left and right and front and rear directions, and the bonding layers are strongly bonded to each other by the adhesive force and the solidifying force of the mortar, so that the continuous base blocks are integrated. It becomes a very stable structure. In addition, since the deformed bars project toward each other and are connected vertically and horizontally, a physically strong structural coupling layer is formed, and even when an earthquake occurs, the vertical and horizontal shaking occurs. It has a strong anti-seismic effect (see Fig. 2, Fig. 3 and Fig. 4).

Further, since the joint slope 13 is formed on the bottom surface of the base projecting portion 11, for example, when a vertical vibration earthquake is applied, the load applied in the vertical direction is applied to the joint slope as shown in FIG. Therefore, it is decomposed into smaller left and right component forces, and therefore cracks occur when an impact that exceeds the strength of concrete is applied, especially the key-shaped parts of the base projection 11 and the column projections 22 and the cracks at the corners. For those that easily generate cracks, the load is disassembled to reduce the impact and avoid cracks as much as possible. Further, the slope makes it possible to move the abutment along the slope when the blocks are combined at the time of construction, thus facilitating mutual joining.

Further, since the block itself can be manufactured in a factory, it is possible to sufficiently adjust the water content, and there is no drawback that the strength is insufficient due to excessive inclusion in order to increase the conventional fluidity. If the joint grooves 31a, 31b, 31c ... Are engraved on the side surface of the block and bolted with iron plates 32a, 32b .. It holds it accurately and does not cause a slump even if there is an earthquake during hardening of the mortar.

Thus, the fabric foundation block of the present invention has completed the construction work, and during that time, at the construction site, it suffices to lay it at a predetermined position after transportation and pour the mortar into the filling recess, so the work is very simple. Becomes

Further, in the block of the present invention, the pillar portion is divided in the longitudinal direction from substantially the center, and one of the left and right sides thereof is extended from the base portion to form a pillar protruding portion and a pillar piece portion on the opposite side. Therefore, there is a drawback that the column protrusions are relatively thin and easily chipped during transportation, but they have the advantage of being easy to fill and remove from the mold when molding.

Further, after the cloth foundation block has been laid, when the piping work for water supply and drainage is performed, the cloth foundation itself has been a hindrance, but as described above, a molded body made of foamed resin is formed on a part of the pillar portion. By embedding, it is possible to destroy the concrete forming the outer thin layer to expose the molded body. Therefore, this can be hollowed out to form a through hole for piping, which makes the piping work extremely easy.

[Effect of device]

 The cloth foundation block of the present invention, which is related to the above configuration and operation, is a basic construction such as a residential building, and the work can be significantly labor-saving and the construction period can be shortened. The problem can be solved by deepening the integral strength with the adjacent blocks and integrating the whole. In addition, problems such as cracks due to the key fitting of the block can be eliminated by the unique structure including the joint slope and the joint cutout, and since there is no deep groove, it is easy to remove the mold during manufacturing. Shows excellent effects.
