Description

[Detailed Description of the Invention] This invention is a non-locking method that allows an existing pool constructed of concrete to remain as it is, and a metal welded pool to be easily constructed using the existing pool frame. This is related to the disclosure of the no-drill repair method.

Previously, renovations of this type of aging pool were planned to include the removal of the pool structure and the application of waterproof mortar, etc., in response to this removal, but as the pool structure became older, As a result, there are countless cracks etc. on the surface of the structure, and water leakage, especially pool water, is applied to the cracks with considerable water pressure, making it difficult to waterproof them and requiring a lot of work and effort to remove them. Moreover, it was not always a satisfactory repair method as it required a lot of noise and generated a large amount of scraped concrete waste.

In addition, even in the so-called cosmetic renovation method in which metal plates are stretched over an existing concrete frame, a large number of reinforcing lining materials are placed between the existing frame and the stretched metal plates to ensure that the interposed metal plates have sufficient water pressure resistance. This was fixed to the main body using all anchors, etc., and the renovation work required a lot of digging work and anchor driving work.

The renovation method according to the present invention was devised especially in view of the inconveniences of the previous renovation methods, and it utilizes the strong load-bearing function of the existing building frame as it is without damaging it in any way. The metal plates that make up the new pool are covered with sand or other cushioning material to form the “surface”.
This is an exceptional design as it supports the new pool, distributes the load of the new pool, avoids applying local forces to the joint edges of the new pool, and prevents accidents such as bursting at the joint edges. This eliminates the need for intervening reinforcing lining material, and removes the joint pipe end of the existing circulating water discharge pipe, that is, the existing mantle pipe, by elution treatment, eliminating the need to remove the mantle flange pipe from the existing frame. This has been made unnecessary.

Hereinafter, the method for repairing an existing swimming pool according to the present invention will be described with reference to an embodiment shown in the attached drawings. First, the method in the first invention involves installing a new pool side wall plate 11 at the lower end of the four peripheral parts of the frame bottom 1 of the existing pool. A concrete foundation 31 for fixing the edge is cast to a size that reaches the tension level of the new pool bottom plate 5, and at that time, a concrete foundation 31 is fixed to the lower edge of the new pool side wall plate 11 in advance or during construction. A fastening member 33 such as a channel material for fastening the connecting member 32 is provided integrally with the concrete foundation 31, and when the fastening member is a channel material, the concrete foundation 31, the concave portion of the channel material faces upward.

The connecting member 32 is planned to be an angle member with a T-shaped cross section as shown in FIG. 1 so that it can be welded to the bottom plate 5 of the new pool. A mode in which it is bent toward the face plate 5 and welded to the bottom plate 5 is also planned.

Next, the grating of the existing drainage basin 2 provided on the bottom 1 of the existing pool frame is removed, and the new drainage basin 3 is installed in the grating installation concave step 2a.
It is installed and erected through packing 4, and the height dimension of this newly installed drainage basin 3 is set to a dimension that reaches the tension level of the newly installed pool bottom plate 5.

The new drainage basin 3 has a cylindrical shape, and a collar 3a is welded to the outer periphery of the lower end, and a collar 3b is welded to the outer periphery of the upper end. Insert the bolt 6 installed vertically into the
In order to integrate the new drainage basin 3 and the bottom plate 5, the bottom plate 5 is welded onto the flange 3b provided on the outer periphery of the upper end of the new drainage basin 3. 2 and the newly constructed drainage basin 3 are connected in a watertight manner.

In addition, a grating 7 is attached to the inner circumferential folding collar 3c of the newly installed drainage basin 3, and this is attached using bolts 8. The grating 7 is designed to fit within a recessed step formed on the surface of the collar 3c of the grating 7.

In addition to attaching the new drainage basin 3 to the existing drainage basin 2, a new circulating water discharge pipe 10 is connected to the existing circulating water discharge pipe 9, and the new circulating water discharge pipe 10 is connected to the new circulating water discharge pipe 10. It is attached to the side wall plate 11 as an integrally fixed opening, and a universal part 10a is disposed in the middle thereof, and the pipe end is inserted and fixed into the existing circulating water discharge pipe 9. be.

Next, in order to fix the positioning angle 13 to the existing overflow groove 14 so as to protrude inward from the side wall 12 of the existing pool, the existing overflow groove 14 is fixed.
After driving the all-anchor 15 and fastening the positioning angle 13 thereto, the side wall plate 11 is integrally welded to the end of the positioning angle 13, and the concrete foundation 31 is attached to the lower edge of the side wall plate 11.
The coupling member 32 is fixedly welded to the fixing member 33 in the fixing member 33, and the positioning is performed by tensioning.

The side wall plate 11 to be stretched is constructed such that reinforcing angles 16 to 16 are welded at predetermined intervals to reliably prevent warping, bulging, etc. of the side wall plate 11.

Thus, when the installation of the new drainage basin 3 and the new circulating water discharge pipe 10 and the leveling of the side wall plate 11 are completed, the flange 32a of the connecting member 32 attached to the lower edge of the side wall plate 11 and the upper end of the new drainage basin 3 are connected. The tsuba 3b provided on the outer periphery is used as the pouring level,
A bottom pressure cushion material 17 such as river sand or mountain sand is poured into the bottom of the existing pool, and then compacted flat by rolling with a roller or the like, and then this poured cushion material 17 is poured.
A bottom plate 5 is stretched and welded to the flange 3b of the newly installed drainage basin 3 and the flange 32a of the connecting member 32 using as a backing material.

Incidentally, before and after the casting of the bottom pressure cushion material 17, the side wall plates 11 based on the positioning angles 13 provided at the upper ends of the side walls of the structure are successively stretched, and the folded bulges on the upper edges of the side wall plates 11 are 11b is set as an overflow level, and a recessed slope is provided laterally from this bulge/convex portion 11b, and a new overflow groove portion 11c is simultaneously formed.

In addition, in the configuration of the new overflow groove section 11c, a new overflow circulation pipe 18 connected to the new overflow groove section 11c is connected to the drainage hole 14a of the existing overflow groove section 14, and excess overflow water is guided to the existing overflow circulation pipe 19. It was designed to be released.

In addition, in conjunction with the installation of the side wall plate 11, a lateral pressure cushioning material 20 such as river sand or mountain sand is filled between the side wall plate 11 and the side wall 12 of the frame, and the side wall plate 1 is
1 was used as the backing material.

Thus, following the renovation of the pool swimming surface, the stage plate 21 shaped as a receiving member for the positioning angle 13 was installed, and the inner bent edge 21a of one side was attached to the existing stage 22 with all anchors 23.
A screw 26 is attached to the angle 24 which is fixed with a caulking 25, and the other end is welded to the rising wall 11d of the newly installed overflow groove section 11c.

In addition, this stage plate 21 is equipped with an appropriate reinforcing material 2 for the purpose of increasing the load-bearing function for swimming, etc.
7 is stretched on the inner wall surface.

In such a swimming pool repair method, the gist of the second invention is that the newly installed circulating water discharge pipe 1
0, the perforated plate attached outer flange pipe 28 of the existing circulating water discharge pipe 9 is heated and eluted with a burner, thereby eliminating the need for any scooping operation of this part.

That is, in the conventional method, the mantle flange pipe 28 for attaching the perforated plate 29 made of cast brass provided at the opening of the existing circulating water discharge pipe 9 was first scooped out, and then treated by cutting it by melting. , a new discharge pipe opening member is connected by attaching a flange material etc. to the cut out innermost steel pipe part.

However, in the conventional method, it takes a lot of time to cut out the existing jacket flange pipe 28, etc., and the continuous construction is complicated and requires many parts, which increases the construction cost. This caused the existing pool structure itself to weaken.

The elution method described above was specially devised in view of the inconveniences in the conventional precedent, and it solves the difference in melting point between the jacket flange pipe 28 made of brass casting and the existing circulating water discharge pipe 9 made of steel pipe material. By focusing on this, by roasting out the outer flange pipe 28 part, there is no need for the operation of scooping out the outer flange pipe 28 in the conventional model, and damage accidents of the existing circulating water discharge pipe 9, which is made of steel pipe material, are prevented. be.

A new circulating water discharge pipe 10 is prepared separately as a substitute for the jacket flange pipe 28 thus eluted, and the new circulating water discharge pipe 10 and the existing circulating water discharge pipe 9 are connected by making the inner diameters the same. This enables construction by simple connection such as fitting and welding the pipe 30.

The renovation method according to the present invention can easily create a strong metal pool by using the characteristic structure mentioned above, especially the non-locking and non-skimming method. This eliminates the labor involved in scooping, as well as the various noises, dust, and large amounts of non-combustible waste generated during scooping, and at the same time reliably prevents wear and tear on the load-bearing properties of the existing pool structure.

In addition, a concrete foundation 31 is provided on the four peripheries of the bottom of the existing pool to ensure complete adhesion of the side wall plate 11 and to withstand water pressure. By using cushioning material, warping and bulging of the stretched metal plates can be effectively prevented, and there is no possibility of accidents such as bursting or distortion of the joint edges even when relatively thin metal plates are stretched. That is.

In particular, in the conventional method, in order to make the metal plate to be stretched into a structure that can withstand enormous water pressure, the backing material is placed so as to cover almost the entire back surface of the metal plate to be stretched, and the shaking of the pool frame Damage to the joining edge due to
In order to prevent accidents such as denting of the contact surface of the backing material, it is securely connected and integrated with the existing pool frame.

Therefore, during construction, a huge number of anchors must be placed on the wall of the existing pool, and each anchor member must be connected to each other, making the construction cost relatively high.

In the renovation method according to the present invention, the stretched metal pool body is supported by simple leveling, and a considerable buffer gap is provided between it and the existing pool frame to prevent the transmission of external vibrations due to earthquakes, etc. It promotes the insulation function and has good heat retention properties in heated pools, etc.

In addition, since there is little damage to the existing pool itself, the strength of the pool frame is not diminished, and even in the case of re-renovation, it is guaranteed that re-renovation and construction can be done by simply removing sand, etc. that has been cast or filled.
