Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention combines a foundation of a wooden construction, an underground beam of concrete construction, an inner wall, an outer wall, a retaining wall, a gate pillar, a formwork or a weir board for constructing a stair riser or a fence. The present invention relates to a structure construction coupling tool.

[0002]

2. Description of the Related Art For example, the construction of a foundation of a wooden construction is conventionally performed as follows. First, dig the ground of the foundation part of the construction site to an appropriate depth, put the stone in this place, and pour concrete from it. Next, the formwork for the foundation is assembled on the concrete, concrete is poured into this formwork, and when the concrete is solidified, the formwork is dismantled.

[0003]

However, the above-mentioned conventional method of constructing a foundation has the following problems. In other words, since the slag of concrete adheres to the frame plate of the formwork that comes into contact with the concrete even after dismantling, it is necessary to clean it so as not to hinder the next construction. Also, oil is applied to the frame plate in advance as a release agent. For this reason, not only the truck but also the clothes of the worker are seriously soiled when the truck is loaded and unloaded. Furthermore, the frame plate of the formwork swells under the pressure of concrete and decomposes in extreme cases, so it is necessary to sufficiently reinforce it. For this reason, many workers are required for assembling and disassembling the formwork, resulting in a high labor cost. If manpower is not secured enough, it will cause a delay in construction period. In order to solve the above-mentioned problems, the inventor of the present application constructs a building member by connecting barrier plates to face each other at a required interval, and installs this at a construction site to place concrete in the space between the barrier plates. A construction method has been devised which does not dismantle as it is even after being filled and solidified, but the present invention provides a means for connecting the dam plates so that they face each other at a required interval.

[0004]

Means for Solving the Problems The constitution of the present invention taken to provide the above means is as follows. According to the first aspect of the present invention, there is provided a coupling tool for coupling a construction member constituting a construction, the coupling tool having an engagement receiving portion, and engaging portions at both end portions, The engagement portion is a coupling tool for constructing a structure, comprising: a coupling member that is formed to be engageable with the engagement receiving portion of the engagement tool. In the second aspect of the present invention, the engaging tool is provided with a fixing and reinforcing means for preventing the engaging tool from coming off when attached to the building member. It is a tool. According to a third aspect of the present invention, there is provided a joining tool for joining building members constituting a building, wherein the joining tool has an engaging receiving portion and engaging portions at both end portions. The engaging portion includes a coupling member that is formed to be engageable with the engaging receiving portion of the engaging tool, and the engaging tool holds the engaging tool base and the engaging tool base. A table, the engaging tool base is inclined so that both side wall portions are narrowed toward the front side, the supporting tool has a holding piece, and the holding piece is provided on both sides of the engaging tool base. It is a construction construction coupling tool in which the front portion is inclined so that the wall portion can be held, and the table is formed so as to be more easily deformed than the engaging tool base. Examples of structures to be used include foundations of wooden construction, underground beams of concrete construction, inner walls, outer walls, retaining walls, gate posts, stair risers or fences. The coupler is attached to a building member such as a formwork or dam used in these constructions. The engagement device is attached to the building member, for example, by being embedded or fixed. The number of them is also appropriately determined.
The material of the building member is not limited, and examples thereof include a concrete plate having a reinforcing material such as a wire mesh inside, a synthetic resin plate, a ceramic plate, a wooden plate, a stone plate, and the like. The length of the joining member is not particularly limited and is appropriately set according to the thickness of the construction member at the time of construction. It is also possible to use a bolt body to movably screw a tightening nut to the threaded portion, thereby making it possible to adjust the support length.

[0005]

Operation: An engaging tool is attached to a required portion of a building member that constitutes a building. In constructing the building member, the building member is arranged at a required position, the engaging portion is engaged with each engaging tool to mount the coupling member, and the other engaging portion of the coupling member is at another required location. To engage the building members. When the engaging tool is provided with the fixing and reinforcing means, the fixing force such as a frictional force is increased when the engaging tool is attached to the building member, and the engaging tool is unlikely to come off the building member. When the engaging tool is made up of the engaging tool base and the table, for example, when the force of the pulling direction acts on the engaging tool due to the pressure of concrete at the time of construction and the engaging tool base tries to shift to the front side, it is deformed. The holding piece of the easy stand tries to spread outward. Therefore,
When the construction member is a concrete dam, a force that is almost perpendicular to the surface of the holding piece acts on the concrete part, and the pulling-out direction force that acts on the concrete part that sandwiches the holding piece is dispersed. Hard to come off.

Referring to FIG. Laying a stone on the construction site, and concrete is horizontally struck from above to make a foundation surface B. A reinforcing bar such as a vertical bar is erected at a position where the building member of the foundation surface B is to be constructed. The fixing position of the height adjusting tool 5 for adjusting the height of the construction unit A1 is determined with reference to a thread (not shown) or the like. Here, the structure of the height adjuster 5 will be described. The height adjusting tool 5 has a rectangular base plate 51, and two adjusting pieces 52, 53 are erected on one end side of the base plate 51 with a space therebetween so that the dam plate 1 can be inserted therein. The adjustment pieces 52 and 53 are provided with a large number of pin holes 54 and 55 having different heights, respectively. Further, the board 51 is provided with nail holes 56 at two positions, and is fixed to the base surface B by the nail 57.

As shown in FIG. 6, the height adjusting tools 5 are arranged at two positions on both ends of the building unit A1 corresponding to the inner dam plate 1 of the building unit A1. After the position is determined, the nail 57 fixes the base surface B. As another structure of the height adjuster,
The width of the adjustment piece may be formed to be slightly wider, and a large number of pin holes may be symmetrically provided on the left and right sides of the adjustment piece. According to this height adjusting tool, the heights of both building units A1 can be easily adjusted with one height adjusting tool if they are arranged at the joint portion of the building unit A1. In addition, the height adjuster is a plate body having a U-shaped cross section, and the intervals between the adjustment plates that are erected on both sides are formed so as to correspond to the intervals between the inner surfaces of the barrier plates 1 that are installed facing each other. It is also possible to insert a pin into the pin hole so that the heights of the inner and outer barrier plates 1 can be adjusted at the same time.

The barrier plate 1 is inserted between the adjusting pieces 52 and 53 so as to be hung on the height adjusting tool 5, with the back surface 10 facing outward. Then, the height of the upper side of the dam plate 1 is determined on the basis of the thread, and the pin 58 is inserted in parallel to the most suitable pin hole of the pin holes 54, 55 of the adjusting pieces 52, 53 to support the dam plate 1. To do. The weir plate 1 is erected on the outer side of the inner weir plate 1 with the backside 10 facing each other so as to sandwich the reinforcing bar. The outer weir plate 1 is connected to the inner weir plate 1 via the connecting member 2 at a constant interval, and has the same height as the inner weir plate 1 whose height has already been set with reference to the thread. Adjusted to. Then, between the joining members 2 at both ends of each building unit A1 and the joining members 2 at the ends of the adjacent building units A1 facing each other, fasteners 25 are respectively laid and tightened and fixed. The space between the units A1 is prevented from expanding beyond the allowable value. As another method, a U-shaped and staple-shaped stopper may be mounted by inserting both ends into the mounting hole 22, or a number wire may be passed through the mounting hole 22 and bound. The outer barrier plate 1 is supported by a required number of connecting members 6 that are bent in a "F" shape. The connecting member 6 has a rectangular metal plate provided with thin portions 61 for bending at the center thereof, and reinforcing portions 62 provided on both sides thereof by embossing, and bent at a required angle at the center to form both ends. It is a structure that adjusts the height from the section to the corner.

A passing adjuster 7 is attached to an upper portion of one end of each building unit A1. Here, the structure of the adjusting tool 7 will be described. The street adjuster 7 has two adjusters 71, 72.

Retaining plates 713 and 723 are provided at the lower end portions of 0 and 720 so as to project outward and have a substantially U shape. Board 71
Slots 714 and 724 are provided on the upper surface of 0 and 720. The width of the adjusting body 71 is the reinforcing plate 72 of the adjusting body 72.
It is formed to be slightly narrow so that it can be slidably fitted between the first and the second parts 722. As shown in FIG. 5, the adjusting bodies 71 and 72 are combined and combined so that the adjusting bodies 71 and 72 come into contact with the outer surfaces of both the dam plates 1, and the bolt nuts 75 are attached to the penetrating portions of the overlapping long holes 714 and 724. Are tightened and fixed.

As shown in FIG. 6, the square steel pipes 8 are alternately mounted inside and outside between the holding plates 713 and 723 of the adjusting tool 7. As a result, it is possible to adjust the length of each building unit A1 over the entire length and also to reinforce the entire structure. At the end of the building unit A1, a flat plate-shaped end plate 9 is nailed,
It is fixed by fixing means such as tightening bolts to prevent concrete from flowing out. Although the end plate 9 is a separate body from the construction unit A1 in this embodiment, for example, a construction unit dedicated to the endmost portion having a closing wall at the end is used to enable quicker construction. Good. If necessary, mortar etc. is filled in the gap between the lower part of each dam plate 1 and the foundation surface B to prevent concrete from flowing out,
Concrete is poured into the space portion 4 so as to be flush with the upper surface of the barrier plate 1 and solidified, and then the square steel pipe 8 and the passage adjuster 7 are removed from the construction unit A1, and the construction is completed. Thus, building unit A1 (and A2, A3, A4)
Is not dismantled even after solidification of concrete, and the dam plate 1 itself becomes a structure such as a foundation.

FIG. 7 is a perspective view showing a second embodiment of the connector for constructing a structure according to the present invention. The structure construction coupling tool has a structure in which the engagement tool 12a and the coupling member 2 are combined. The coupling member 2 has the same structure as that shown in FIG.
The engaging tool 12a is formed by bending a metal plate, and includes an engaging tool base 120a and a stand 127. Engaging tool base 120
Although a has substantially the same structure as the engaging member base 120, both side wall portions 126 are inclined so that the front side is narrowed, and both engaging pieces 121 are inclined toward the inside of the accommodation recess 122. The base 127 has a back plate 128, and the holding piece 1 is tilted so that the front side is narrowed on both sides of the middle part of the back plate 128.
29 are provided, and mounting pieces 130 are provided at four positions on the upper and lower portions so as to project to the back side. Each mounting piece 130 is provided with an insertion hole 131 for mounting on the reinforcing bar 9 for reinforcing the dam plate 1. Note that the stand 127 is formed of a thin metal plate and has a slightly lower rigidity than the engagement tool base 120a. In the drawings, the same or equivalent parts as those of the engagement tool 12 shown in FIG. 1 are designated by the same reference numerals.

According to the engaging tool 12a having this structure, the fixing to the dam plate 1 is more reliable than the engaging tool 12.
That is, as shown in FIG. 7, after attaching the engaging tool 12a to the dam plate 1 and engaging the joining member 2 to join the dam plates 1 on both sides, when the space is filled with concrete, the pressure is applied. The pulling-out force of the connecting member 2 acts on the fitting 12a. At this time, since the engagement piece 121 is inclined toward the inside of the accommodation recess 122, it is strong against the tensile force of the coupling member 2 and is unlikely to be deformed or damaged. Further, when the engaging tool base body 120a tries to shift to the front side when a tensile force is applied to the engaging tool 12a, both holding pieces 129 of the stand tool 127, which are easily deformed, try to spread to the outside. A force substantially perpendicular to the surface of the holding piece 129 acts on the concrete portion 1 of FIG. By this, the force in the pull-out direction that acts on the concrete portion sandwiching the holding piece 129 is dispersed,
The engagement tool 12a does not easily come off. The present invention is not limited to the illustrated embodiments, and various modifications can be made within the scope of the claims.

[0017]

The present invention having the above-mentioned structure has the following effects. (A) Unlike the construction method using a conventional formwork, the structure construction coupling tool according to the present invention is constructed so that the construction member itself does not become disassembled even after solidification of concrete and becomes a construction. In the method, the joining of the building elements can be done easily and reliably. (B) Since the fixing force to the building member is increased in the structure construction coupling tool having the fixing and reinforcing means, for example, after the construction member is coupled by engaging the coupling member at the time of construction, concrete is added to the space portion. When filled, even if a force in the pull-out direction by the coupling member acts on the engagement tool due to the pressure, the engagement tool is unlikely to come off. (C) In the connector for constructing a structure according to claim 3,
During construction, for example, when the force of the connecting member pulls out to the engagement tool due to the pressure of concrete, and the engagement tool base body tries to shift to the front side, the holding piece of the stand, which is easily deformed, tries to spread to the outside. Therefore, a force almost perpendicular to the surface of the holding piece acts on the concrete portion of the building member. As a result, the force in the pull-out direction that acts on the concrete portion sandwiching the holding piece is dispersed, so that the engaging tool is more unlikely to come off.
