The present invention relates to a base plate for supporting a lower surface so that an object or a building having a large load is stably seated on the ground, and more particularly, to a basic reinforcement configured to support a large load even if the volume is small. will be.

Generally, in order to prevent ground subsidence due to the weight of the building, a base plate is constructed in the lower part of the building so that the building load can be evenly transmitted to the ground. The conventional base plate is designed with a thick reinforced concrete structure. Has been.

Recently, as the size of buildings increases, the load applied to the foundation plate also increases. In the case of the conventional base plate, the flexural strength and shear strength were increased by increasing the size of the base plate made of a general reinforced concrete structure according to the magnitude of the load applied.

Therefore, as the size of the base plate increases, the depth of the trench is deepened so that the base plate can be buried in the ground. As a result, the size of the rock crushing work and the base plate manufacturing work to bury the base plate is increased, there was a problem that the construction period and the construction cost is excessively consumed. In particular, when the lower part of the building is a rock, it is very difficult to deepen the trench, so the construction period and construction cost are greatly increased.

In addition, when the foundation plate is constructed with reinforced concrete as in the related art, as the depth of the trench deepens, contact between the foundation plate and the groundwater becomes inevitable. Thus, when the foundation plate comes into contact with the groundwater for a long time, the quality of the reinforced concrete is improved. There is a disadvantage in that it is not possible to support the load of the building normally.

In addition, when the trench was to be deep, it had to be inclined so as to widen the upper side in order to prevent the collapse of the wall and to secure work spaces. Thus, when the trench is inclined so that the wall is inclined, damage to the adjacent buildings has a disadvantage that there are many difficulties in construction in the place where the buildings are concentrated. In addition, when the trench is inclined so that the upper part is widened, there is a disadvantage in that the space to which the concrete is to be placed increases, thereby wasting concrete.

The present invention has been made to solve the above-described problems, it is possible to distribute the external load more effectively even if the foundation is not large construction, and to provide a foundation reinforcement is configured so that deformation does not occur even if a large load is applied. There is this.

Basic reinforcing material according to the present invention for achieving the above object is formed in a plate shape, and at least two basic iron plate arranged upright; Reinforcing steel plates coupled to upper ends of both ends of each basic steel plate; It comprises a long iron rod coupled to the reinforcing iron plate so that both ends parallel to the surface of the base iron plate.

When the basic steel plates are arranged in a parallel structure, the reinforcing steel plates are independently connected to the upper end of one end and the other end of each basic iron plate, and when the basic steel plates are arranged in a radial manner, the reinforcing steel plates surround both ends of each basic steel plate. If the base plate is arranged so as to overlap at a right angle, the reinforcing iron plate is coupled to surround both ends of each base plate.

In addition, in the case where the basic iron plates are arranged radially, a central pipe having a central axis in the vertical direction is provided at a portion where the basic iron plates overlap, and each basic iron plate is cut along a vertical center line, and then the inner end thereof is an outer surface of the central pipe. It is preferred that it is configured to be welded to.

The base iron plate is provided with a groove which is formed to be concave downward in the center of the upper side, wherein the groove may be formed in a bent shape or may be formed in an arch shape.

The long bar is located to have a length in the width direction of the base plate, and is coupled to the reinforcing iron plate in a pair to be spaced apart at regular intervals to the left and right around the point to be combined with the base iron plate.

The reinforcing steel plate is formed with a first through hole at a point corresponding to the end of each long steel bar, and the long steel bar is coupled so that both ends protrude out of the reinforcing steel plate through the first through hole and protrude out of the reinforcing steel plate. At both ends, a first male thread is formed. At this time, the long iron bar is coupled to the reinforcing steel plate by a first nut formed in a structure that can be coupled to the first male thread.

In addition, the base iron plate is formed with one or more second through holes penetrating in the arrangement direction of the base iron plate; The basic reinforcing material according to the present invention is configured to include a connecting iron bar that is sequentially penetrated through the second through hole of each basic iron plate coupled to each basic iron plate.

The connecting iron bar is coupled so that both ends protrude to the outside of the basic iron plate, and both male threads are formed at both ends protruding to the outside of the basic iron plate. At this time, the connecting iron bar is coupled to the base iron plate by a second nut formed in a structure capable of coupling to the second male thread, as in the case of the long iron bar.

At this time, the number of the base plate 100 arranged in parallel may be increased or decreased according to various design conditions such as the load of the building. When the area of the building to be constructed is large, it can be used by connecting a plurality of basic reinforcement shown in Figure 1, it is possible to arrange each foundation reinforcement to be evenly distributed even if the load is applied in any direction.

3 is a front view of a reinforcing steel plate of the basic reinforcing material shown in Figures 1 and 2, Figure 4 is a cross-sectional view of the long bar and the surrounding taken along the line A-A of FIG.

As shown in FIG. 3, the reinforcing iron plate 200 applied to the present invention is formed to be elongated in the horizontal direction, and has a first penetration of a size that allows the penetrating iron bar 300 to penetrate to a portion that is coupled to the long iron bar 300. Spheres 210 are each formed.

Thus, as shown in Figure 4, the long wire bar 300 is coupled so that both ends protrude out of the reinforcing steel plate 200 through the first through hole 210 of the reinforcing steel plate 200. At this time, the first male thread 310 is formed at both ends protruding to the outside of the reinforcing steel plate 200, the long iron bar 300 is a first nut formed in a structure that can be combined with the first male thread (310) ( 320 is fixedly coupled to the reinforcing iron plate 200. As the first nut 320 is tightened, the reinforcing steel plate 200 is in close contact with the side surface of the base steel plate 100.

At this time, when the long iron bar 300 is coupled to the reinforcing iron plate 200 so as to be spaced apart from the base iron plate 100 by a predetermined interval or more, reinforcement of the portion in contact with the base iron plate 100 by the fastening force of the first nut 320. Moments are generated in the iron plate 200. Accordingly, since the shape of the reinforcing iron plate 200 is deformed, it is preferable that the long-barbed iron rod 300 is coupled to the reinforcing iron plate 200 to be located at a point close to the base iron plate 100 as shown in FIG. 1.

FIG. 5 is a side view of the basic iron plate of the basic reinforcing material shown in FIGS. 1 and 2.

As shown in Figure 5, the base plate 100 is applied to the present invention, the groove is formed in a portion of the upper side so that the load applied to the upper side is easily transferred to the side, the groove is not concentrated stress It is preferable that it is formed of an arc-shaped groove 110 having an arch shape. The principle and structure in which the load applied to the upper side is transmitted to the side will be described below with reference to the separate drawings.

The second through-holes 120 of the size that can be penetrated by the connecting iron bar 400 is formed at the portion where the connecting iron bar 400 is coupled. Therefore, as shown in Figure 1, the connecting rod 400 is erected to be spaced apart at regular intervals through the second through-hole 120 of each of the basic iron plate 100 arranged in a parallel structure sequentially so that both end portions The outermost both of the base iron plate 100 is coupled to maintain the protruding state. At this time, a second male thread 410 is formed at the end of the connecting iron bar 400 protruding to the outside of the outermost base iron plate 100, and the second nut is formed to be coupled to the second male thread 410. It is coupled to the base iron plate 100 by 420.

In addition, the base plate 100, which is not fixed to the connecting iron bar 400 by the second nut 420, and is positioned so that the connecting iron bar 400 simply penetrates, the first contacting the connecting iron bar 400 2 through hole 120 is welded to the connection to the connecting rod 400 to be fixed.

The coupling iron bar 400 coupled as described above has an effect of maintaining the interval between the lower ends of the basic iron plate 100 and at the same time, preventing the basic iron plate 100 from being separated from the concrete after curing of the concrete is completed. .

6 is a side view of the base iron plate according to another embodiment.

The grooves formed in the basic iron plate 100 may be applied to the bending grooves 110a in which the side walls and the bottom surface form a straight line as shown in FIG. 6.

When the groove of the basic steel plate 100 is formed in the shape of the bent groove (110a), compared to when the groove is formed in the shape of the arc groove (110) shown in Figure 5, the load applied to the upper side is transmitted to the side In terms of the effect of the similar to each other, but the advantage is very easy to manufacture.

7 is a schematic side view showing the direction of stress generated in each part by the load applied to the basic reinforcing material according to the present invention.

As shown in FIG. 7, when a vertical load is applied to the upper part of the basic reinforcing material according to the present invention, the applied vertical load is primarily supported by the base steel plate 100.

At this time, if the basic iron plate 100 to be applied to the present invention is formed in a rectangular flat plate shape without the circular arc groove 110 on the upper portion, the vertical load is not evenly applied to the entire upper surface of the basic iron plate 100 on one side. When applied so as to be biased, there is a fear that the base plate 100 is broken. However, when the circular groove 110 is formed in the upper portion of the base iron plate 100, as shown in Figure 5, even if the vertical load is applied so as to be biased to one side, the base iron plate 100 is not broken and both upper ends open to the left and right sides Or bend to the front or back. When the distance between the upper ends of both sides of the basic iron plate 100 is applied, the tensile force is applied to the long rod 300, the steel is a material of the long rod 300 is weak to the compressive force, but the strong tensile strength 100, the upper end of both sides will not be deformed.

At this time, since the tension bar is not applied to the long bar 300, only the tensile force is applied, it is preferable that the rigidity of the tissue rather than the material having a large rigidity is made of a material having a high tensile strength. This may be applied by being deformed into an iron wire shape rather than an iron rod shape.

The circular arc groove 110 for opening the upper center of the base iron plate 100 may be applied by being deformed into a groove having a line shape consisting of two or more straight lines. However, since the stress is concentrated at the vertex, there is a risk of fracture due to crack generation, the arc groove 110 is preferably formed to form a curved shape. In addition, in addition to the effect of preventing the breakage of the base plate 100, in order to obtain the effect that the applied load is more evenly distributed throughout the base plate 100, the arc groove 110 is shown in FIG. It is most preferably formed in an arcuate shape that is symmetrical.
