Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to construct an important basic part of construction in the construction field, particularly wooden construction as well as steel-framed construction, etc. exactly, promptly and economically as shown in the drawings. This is a method of constructing an integrated construction method for concrete foundations that can shorten the construction period.

[0002]

2. Description of the Related Art In the conventional construction technique, it occurs because the existing ground is continued to be excavated by excavating the existing foundation as it is according to a work display called a method of instructing the arrangement of the building position and the constituent foundation set on the existing foundation. Soil piled up on both sides of the foundation array, which not only slowed down the work speed in the direction that the work progress was delayed, but also collapsed the soil generated at the top of the crushed stone terrain and significantly deteriorated the basic performance, that is, the collapsed soil. It is common knowledge that pump cars are also used for pouring bottom concrete as it is, and even now it is common practice to collapse soil on the bottom plate, step on the bottom concrete, pile up In the condition of walking and working on the generated soil, this condition had to be tolerated. At least one day will be left at the site until the bottom plate where concrete is poured is hardened, and after hardening, the beam width will be marked and the installation of the beam frame will be started for the first time. Insert the lower part of the beam frame on the beam frame and the bottom plate by tining, set the beam width of the lower part by nailing according to the beam width, and set the beam frame to the beam frame joint with the beam frame After joining the surfaces with nails, piled up piles of small angled piers and nailed to the top of the beam frame to align the matrix, so there are many drawbacks that the beam frames are not aligned like a string, It was common sense to reproduce the defects as they were in the finish as well, so it is fatal as a construction worker to finish the outside of the building evenly by plastering etc. together with the finish of the building. Was becoming.
Since the worker continued to walk violently on the upper part of the bottom plate even after it hardened, the generated soil was covered with soil and cleaned, but the performance of the adhesive surface between the bottom plate and the beam was significantly deteriorated. This is because the top of the workers is a bad practice that has been continued without making such appropriate reforms.

[0003]

It is pointed out that since the bottom plate and the beam part can be integrally cast, the bottom plate and the beam part are hit twice, so that "slip" occurs due to a large vibration due to an earthquake or the like. However, the purpose is to almost prevent this "slip".

By carrying out the amount of soil from the existing ground to the top of the bottom plate and subsequently excavating the amount of the bottom plate and crushed stone topography to be excavated subsequently, it is possible to secure the accumulation site for the amount of subsequent generated soil. The purpose is to improve the efficiency of subsequent work until completion.

Excavation for excavation of the bottom plate and crushed stone terrain should be carried out so that the bottom plate is set as shown in the drawing (conventional technique) so that soil and foreign matters as specified in (Conventional Technology) are not mixed in as much as possible.
In addition, by securing the horizontalness of the bottom plate, the horizontalness of the beam frame is also secured at the same time, and the aim is to complete an ideal foundation that can eliminate nailing work altogether in order to improve performance.

[0006] The beam frame can be installed in parallel with the beam frame loading hardware installed on the bottom frame and continuously and continuously by using the beam frame fixing hardware, the width stop hardware, the beam frame floating prevention reinforcing bar and the fixed hardware. The aim is to do no nailing work quickly and economically.

[0007] In the conventional single-casting that has been repeatedly attempted, the beam frame was lifted by the concrete inflow work and the beam frame floated up, and repair work was required to complete the foundation. Intended to be removed.

[0008]

[Means for Solving the Problems] Regarding the construction of a concrete foundation made of wood as well as steel, which has been conventionally constructed, the performance far from that shown in the instructional drawing has been hidden, and it has been possible to deal with it. As described in (1. Technology), it was the situation that the defective factor could not be removed. It is proved that the cause is that the craftsman as well as the master who receives the basic construction could not reform it after analyzing the construction structure, and that the same work was repeated over many years. It According to this method, the work is simplified by improving the tools that are said to be ideal and using the developed materials, so if there is one with a construction configuration and construction technique, an amateur will help you. You can build an ideal foundation for the street.

[0009]

[Function] In the basic cross-sectional view indicated in the design drawing, there is no drawing that clearly shows the joint between the bottom plate and the beam portion, and the design drawing is the integrated cross-sectional view. It was the conventional construction technology that could not be done according to the design drawing. According to this construction method, not only the foundation according to the design drawing can be added but also the added value becomes high and not only the defective factors generated by the "conventional technology" can be removed, but also quickly, the construction cost can be reduced, the construction period can be shortened, Furthermore, the effect is remarkable because it can contribute economically and contributes to the construction field.

[0010]

[Examples] A of FIG. 1 explained with reference to the attached drawings shows a cross section of the construction drawing up to the completion of construction, and B shows a plan view thereof. The setting GL and the amount of soil 10 up to the top of the bottom plate, that is, the cutting ground The amount of disposal is 12, the topography of crushed stone, and the bottom plate 11.
Dispose of a considerable amount of. Continued crushed stone topography 12 and bottom 11
The root cutting excavation will be dug up to the root cutting surplus line, and the excavated soil will be collected in the largest room on the ground surface. Subsequently, the crushed stone topography 12 is completed, and the bottom fixed metal piece for 3 corners shown in FIG. 4B is temporarily placed at a predetermined location on the completed crushed stone ground.
After that, the bottom plate frame 1 is cut into a predetermined length and inserted into the bottom plate fixing hardware 3, but when it is necessary to continue the length, FIG.
After completing the construction by continuing the bottom frame 1 using the straight line of A, the sand or the flat stone, which is a suitable animal, is inserted under the bottom frame fixing hardware 3, and the horizontal adjustment is completed.

The beam frame loading hardware 4 shown in FIGS. 1, 2 and 3 has a 4'separator previously incorporated in the top end of the bottom frame 1 adjusted to a constant height. As shown in FIG. 2, the arrangement procedure is about 3 pieces per 1820 mm, but the beam frame loading hardware 4 is combined with a spacer 4'4 'so that it can be adjusted according to the beam width of the beam portion 9. is there.

It is effective in terms of work to dispose the beam frame loading hardware 4 and place the beam frame 2 and set the beam frame 2 from the corner so that half of the beam frame 2 can be easily treated. Align the left and right objects with the width stoppers 5 and make the beam frame 2 self-supporting.
Therefore, the beam frame 2 can be further stabilized when the beam frame fixing hardware 6 which is successively connected and extended is provided with the anti-floating reinforcing bar 7 in a position where it is tightened by hand. Completion of placement is shown in Figure 1B.

After the installation of the predetermined beam frame 2 and the respective members is completed and installed in parallel, the concrete pouring work is performed. However, as shown in FIGS. 1, 2, 3 and 6, the beam frame 2 is a small angle reinforcing the temporary frame veneer. A beam frame 2 is used in which a cross-section of a small-angled peg which is reinforced by striking a peg to maintain the strength of the veneer but reinforced at the bottom end of the veneer is reinforced 20 mm above the bottom end of the veneer. This is the concrete of the bottom plate 11 and the beam part 9 is the beam frame 2
Because the concrete flows in from the upper part of the beam frame 2 toward the bottom plate 1, the force of pushing up the lower end of the beam frame 2 is 100%.
Although the structure is designed to reduce%, in case that an excessive pushing force is applied, the beam frame lifting prevention reinforcing bar 7 shown in FIGS. The construction of the beam frame 2 need not be nailed at all, and all can be constructed by hand tightening, and the eccentric foundation can be constructed in the same manner.

[0014]

The present invention is configured as described above and exhibits the effects described below.

Since the existing ground is not excavated as it is, the inside of the work place is neat and wide, and the work is easy, and the material can be easily carried in as well as the materials to be continuously constructed, and the work efficiency is remarkably improved. The bottom frame could be set according to the design. This effect was able to be assembled and formed without inserting any nails by simply inserting the bottom plate frame cut according to the drawing into the fixed metal plate for bottom plate, so that the work efficiency was remarkably improved.

For assembling the beam frame, the beam frame is placed on the beam frame loading hardware and the width stop hardware is mounted. The beam frame is also connected by simply mounting the beam frame fixing hardware and tightening the predetermined bolts by hand. Assembly is complete. Furthermore, when the anti-floating rebars are laid and the matrix of the beam frame is aligned on only one side, the opposite side is also aligned with one shot due to the effect of the width stop metal fitting, and the anti-floating rebars are fixed at the aligned position.
Since the setting of the beam frame is completed, after tensioning threads to the left and right, which was done conventionally, after striking a small square bar at the top end of the beam frame in the place aligned left and right to fix the width of the left and right beams (prior art) A small-angled splint is pierced into the piled soil, and one of them is fixed to the top of the beam frame with nails, and preparation is made to prevent the beam frame from moving during concrete placement. Could be eliminated at all. Moreover, including the fact that only one pump car was used for concrete pouring, we succeeded in reducing the workforce by 35% and the cost by 60%, including the fact that we were able to shorten the construction period by 25% ( (Conventional technology) It is also characterized by the fact that it is a very economical method for constructing a concrete-body-casting foundation that can remove all of the poor performance factors associated with the completion of the foundation.

It is characterized in that it is possible to secure the remaining place of. 2. A building formed by unloading soil from the initial soil volume (10) and subsequently unloading soil from the bottom plate (11) and crushed stone topography (12). After accumulating in the proper place inside, crushed stones will be constructed at the root cutting site. After the crushed stones have been lifted, the bottom plate frame (1) is roughly placed temporarily after placing the bottom plate fixed hardware (3) (B) for corners shown in [Fig. 4]. The placement is completed by cutting into a predetermined length. When the length of the bottom board frame (1) is insufficient, the bottom board fixed hardware (3) can be connected by using the straight line (A). This work is characterized in that the bottom plate (11) can be quickly constructed without using any nails to form the bottom plate frame (1). 3. A bottom plate (1) shown in (FIG. 1, FIG. 2, FIG. 3)

In order for the left and right sides to stand on their own, the width stop hardware (5) and the beam frame fixing hardware (6) for the straight line (A) and the corner (B) are erected and self-supported by tightening the predetermined bolts by hand. The beam frame (2) is formed, and no nails are used in this configuration, and the lower end of the beam frame (2) is automatically stabilized by the separator (4 ') of the beam frame loading hardware (4). It is characterized by being installed in. 4. Concrete having pump pressure and dropping pressure because the lower end of the beam frame (2) shown in (FIG. 2) is generally poured and poured from the upper part of the beam frame (2). Since the force that pushes up the beam frame (2) acts when the water flows out from the beam frame (2) toward the bottom frame (1), the conventional integrated casting has been unsuccessful, and it is difficult to repair the unsuccessful part. Since it is slidable, the conventional construction method was that no single casting was performed. In order to reduce this pushing-up action, the reinforcing lower bar of the temporary frame veneer of the beam frame (2) was reinforced from the lower end of the veneer to the upper part by 20 mm, and the reinforcing bar whose cross section was processed into a triangle was used as a reinforcing material. In order to absorb the excessive pressure, the rising prevention reinforcing bar (7) is installed on the top end of the beam frame (2) shown in (Fig. 1, Fig. 6) to prevent secondary pressure. In addition to this, by aligning the streets on one side when aligning the matrix of the beam frame (2), the streets of the related beam frame (2) can be automatically aligned and the roots of the anti-lift bars are fixed. This has the characteristic that it can withstand the extreme shock of concrete pouring. It is characterized by a construction method that allows the concrete foundation to be completed easily, quickly and economically without using any nails for the construction of the beam frame (2).
