Description

Prop fixing apparatus for foundation concrete for fences

The present invention relates to a support for the support of the foundation concrete for the fence for firmly fixing the support vertically installed on the foundation concrete for the fence embedded in the ground.

In general, when you want to install a fence, the foundation concrete is first buried in the ground, and then the pillars are vertically inserted into the holes drilled in the foundation concrete, and then the barbed wire is installed on the pillars.

The foundation concrete for the fence of the prior art is configured to insert a strut in a hole formed in the center thereof.

However, in the prior art, when the inner diameter of the hole formed in the center of the foundation concrete is smaller than the outer diameter of the support, the support cannot be inserted into the hole, and when the inner diameter of the hole and the outer diameter of the support are the same, the work is inserted into the hole. This is not only very hard, but also can not be inserted deeply to the shore, the installation state of the shore is not secure, causing the installation of the fence becomes poor, formed in the center of the foundation concrete to solve such problems When the hole is formed to be a little larger than the outer diameter of the support, there is an advantage that the support can be easily inserted into the hole. On the other hand, since the support is loosely inserted, the support moves in all directions. Barbed wire sway due to the movement of the fence The problem is that the condition is bad, and when the prop and the barbed wire are shaken severely, the shaking is transmitted to the foundation concrete. When the foundation concrete is not fixed, the soil around it is relaxed with the foundation concrete. This appears, so that the soil around the loosening leads to the loss of rainy weather, and later, the foundation concrete itself protrudes to the ground, so that the problem of the collapse of the fence may occur.

The present invention was created in order to solve all the problems shown in the prior art as described above, embedded with a fixed ring body with a female thread in the hole formed in the center of the foundation concrete, one side is cut off while the male ring is formed on the outer peripheral surface of the fixed ring body As a means for screwing the crimping ring body, it is possible to firmly hold the support post inserted into the hole formed in the foundation concrete, and to install the fence more firmly, and also to install it perpendicular to the foundation concrete. It is designed for other purposes to provide a work tool that can be quickly carried out to securely install the fence holding firmly so that it can easily perform the rotation of the crimping ring to be assembled to the fixed ring body.

Reference numeral 1 denotes a base concrete, and the base concrete 1 is made of a means for filling a mold with concrete mortar or cement mortar (hereinafter referred to as mortar) in a mold and then demolding it.

Before filling the mold with mortar, the hole 11 is formed in the center of the foundation concrete 1 by molding the foundation concrete 1 by filling the mortar with the cylindrical fixing ring body 2 installed in the mold. The upper end of the fixed ring body (2) is to be molded.

On the inner circumferential surface of the fixed ring body 2 is formed a female screw portion 21 having an inclined surface gradually narrowing toward the center from the upper end to the lower end, and on the outer circumferential surface of the fixed ring body 2 of the base concrete 1 In the state embedded in the upper end of the hole 11, the rotation and separation prevention projections 22 are formed to prevent rotation in the left and right directions and prevent the separation in the up and down directions at the same time.

The rotation and departure prevention projections 22 may be formed in a structure protruding in a band in the circumferential direction and the up and down direction, as shown in the drawing or the outer circumferential surface of the fixing ring body 2, although not shown in the drawing It is also possible to prevent the rotation and separation of the fixing ring body 2 in the form of a phase.

The pressing ring body 3 assembled into the fixing ring body 2 is formed in a cylindrical shape with a cutout portion 31 in which one side is cut in an up and down direction, and the outer circumferential surface thereof gradually goes outward from the bottom to the top. The male screw part 32 which has the inclined surface which spreads is formed.

In addition, the upper end of the pressing ring body 3 may be formed between each of the plurality of engaging projections 34 that protrude at a predetermined interval to the engaging recess 33a that can be rotated by the work tools (4a, 4b) In addition, a locking recess 33b, such as a hole drilled facing each other, may be formed on both sides of the upper end of the pressing ring body 3 together.

Work tools (4a) (4b) for rotating the pressing ring body 3 is one projection 42 is formed at the tip of the arc surface 41, as shown in Figure 7, the arc surface 41 as shown in FIG. Several protrusions 42 are formed, and in the case of the assembling tool 4a having one protrusion 42 formed at the tip of the arc-shaped surface 41, the hook recesses formed at regular intervals on the upper end of the pressing ring body 3 ( The pressing ring body 3 can only be rotated in the tightening direction or the unwinding direction by means of bringing the arc surface 41 into close contact with the upper end of the pressing ring body 3 while the protrusion 42 is inserted in any one of the 33a). Instead, the pressing ring body 3 can be rotated in a state where the one protrusion 42 is inserted into the hook recess 33b formed as a hole, while the protrusion 42 has several protrusions 42 formed thereon. In the case of the tool 4b, a plurality of projections 42 are selected by selecting several locking recesses 33a formed at regular intervals on the upper end of the pressing ring body 3. To engage kkiwojun state is capable of operating the rotary compression ring body (3).

The pressing ring body 3 is inserted into the upper end of the fixed ring body 2 embedded in the upper end of the hole 11 of the base concrete 1, and then screwed into the female thread gradually narrowed toward the lower end ( The male thread portion 32 screwed to the 21 is gradually tightened, wherein the pressing ring body 3 itself is tightened elastically by the cutout portion 31 formed on one side, and the outer peripheral surface of the support 5 is strongly tightened. It will be compressed.

As another embodiment of the present invention 5 and 6 is to be embedded long to the bottom of the hole 11 while being in close contact with the bottom of the fixing ring body 2 embedded in the upper end of the hole 11 of the base concrete (1) As an embodiment in which the hollow tube body 6 is formed, as shown in FIG. 5 of the embodiment, the hollow tube body 6 is formed to be integrally formed to extend from the lower end of the fixed ring body 2, or as shown in FIG. The hollow tube 6 may be formed into a structure for screwing the fixed ring body (2).

The hollow tube 6 integrally formed or screwed to the bottom of the fixed ring body 2 as described above prevents mortar from flowing into the interior of the fixed ring body 2 when the basic concrete 1 is formed into mortar. Thus, mortar is not attached to the female screw portion 21.

On the other hand, the fixing ring body 2 and the pressing ring body 3 of each of the above-described embodiments has a strength capable of firmly fixing the support (5) and is preferably made of a metal or plastic, such as corrosion resistance, Particularly, in the case of the pressing ring body 3, it is preferable to use a material having a good elastic force, which is when the pressing ring body 3 is screwed into the stationary ring body 2, and the pressing ring body 3 itself is a cutout 31. When it is elastically tightened and loosened, the elastic ring is restored to its original state, so that the pressing ring body (3) holding the support (5) for repairing the fence may be removed from the stationary ring body (2). This is to facilitate restoration and reassembly.

The operation of the present invention configured as described above will be described.

First, the base concrete 1 is buried in the ground so that only the upper part is exposed, and then the lower end of the strut 5 is inserted into the hole 11 from above the base concrete 1, wherein the strut to be installed ( 5) in the state in which the crimping ring body 3 is pre-inserted, the lower end of the crimping ring body 3 is inserted into the strut 5 and inserted into the lower end of the hole 11 deeply through the fixing ring body 2. While inserting the lower end of the fixing ring body 2 into the upper end of the pressing ring body 3 is inserted into the upper end of the fixing ring body (2).

As described above, the outer diameter of the male screw portion 32 of the lower end of the pressing ring body 3 inserted into the upper end of the fixed ring body 2 is slightly smaller than the inner diameter of the female screw part 21 formed at the upper end of the fixing ring body 2. The male threaded portion 32 of the lower end of the ring body 3 is loosely assembled to the female threaded portion 21 of the upper end of the fixed ring body 2 so that an operator can easily screw the crimping ring body 3 with his own hand. Although it can be, the male screw part 32 formed on the outer circumferential surface of the crimping ring body 3 forms an inclined surface whose outer diameter gradually increases from the lower end to the upper end, while the female thread part formed on the inner circumferential surface of the fixed ring body 2 is formed. (21) forms an inclined surface whose inner diameter gradually decreases from the upper end to the lower end, so that the male ring part 32 of the pressing ring body 3 is gradually screwed into the fixing ring body 2. And The pressing ring body 3 itself is elastically tightened by an incision 31 cut in one side thereof while being in a state of being tightly screwed into the female threaded portion 21 of the ring body 2, and thus the pressing ring body 3. When the tightening) begins to tighten, it becomes difficult to tighten the screw of the pressing ring body 3 by the hand of the worker.

Therefore, when it becomes difficult to screw the pressing ring body 3 by hand, the work ring 4a or 4b shown in FIG. 7 or 8 is selected to continuously screw the pressing ring body 3, and FIG. 7 In the case of the work tool 4a shown in the drawing, the protrusions 42 formed at the tip of the arc-shaped surface 41 are caught by the catching recesses 33a formed at regular intervals on the upper end of the pressing ring body 3 or face each other. The work tool 4a is screwed in the screw tightening direction in a state in which the projection 42 is inserted into one of the penetrating recesses 33b and the arc surface 41 is brought into close contact with the upper end of the pressing ring body 3 (see FIG. 7). In the case of the work tool 4b of FIG. 8, in the case of the work tool 4b of FIG. 8, a plurality of protrusions 42 protruding at a predetermined interval from the arc surface 41 are formed at the upper end of the pressing ring body 3. In the state fitted to the work tool (4b) is rotated in the screw tightening direction, wherein the work tool (4a) 4b is capable of screwing the pressing ring body 3 with a small force by the lever principle. Therefore, the worker is able to forcibly screw the pressing ring body 3 to the stationary ring body 2 by using the work tools 4a and 4b, which is continuously screwed into the stationary ring body 2. As the pressing ring body 3 itself is screwed, the inner diameter of the support ring 5 is gradually narrowed by the cutout portion 31, thereby compressing the outer circumference of the support column 5, so that the support column 5 has a hole 11 of the base concrete 1 ) Is firmly installed vertically by the pressing ring body (3) screwed to the fixing ring body (2) while being inserted into.

The holding device consists of a holding ring body (2) buried in the upper end of the hole 11 of the base concrete (1) and the pressing ring body (3) elastically tightened while being screwed into the fixing ring body (3) (5) can be fixed so as not to shake, and the fence can be installed more firmly.

According to the present invention as described above by means of screwing the pressing ring body formed with a cut in one side to the fixing ring body embedded in the upper end of the hole formed in the center of the base concrete, so that the pressing ring body is gradually tightened to compress the outer circumference of the support There is an effect that can be fixed and installed more firmly, and also formed a recess in the top of the pressing ring body can be rotated with a work tool to tighten the pressing ring body with a small force as a work tool to install the support work There is an effect that can be carried out more quickly, and since the fixing ring body is molded in a state that is pre-inserted in the mold when forming the foundation concrete, not only the buried work of the fixing ring body is easy but also the outer peripheral surface of the fixing ring body Rotation and separation prevention projections are formed embedded in the base concrete The ring ring does not have a phenomenon that the separation from the base concrete does not occur, and the phenomenon that the rotation of the screw when tightening the compression ring body has the effect that does not occur, and also the hollow tube body formed at the bottom of the fixed ring body integrally or by screw assembly It is a useful design that can be expected to have the effect of preventing the mortar from adhering to the female thread formed on the inner circumferential surface of the fixed ring body by forming the foundation concrete as a bonded structure.
