Description

Construction Materials for Standing Water

This design is used for index and self-repair for underground buildings or civil engineering structures. More specifically, it is applied to concrete structures before concrete placement such as H-beams or pipes, and thus increases adhesion to H-beams or pipes. It relates to an index member in consideration of the index of water expansion by contact with water.

In general, civil engineering works or structures use waterproofing materials to completely prevent inundation or leaks that occur inevitably. I use it.

The water expansion index material is a volume expansion is made in contact with water, moisture, and is the most ideal and essential material as a professional index product that prevents the infiltration hole due to leakage by its own sealing effect.

In particular, in the construction of the above-described concrete structure, it is installed in the concrete joint site to block the water path while the water flowing from the joint site is in contact with the water while the magnetic material expands by more than 600%. If you look at the usage, it is applied to the H-beams, through passages, fire hydrants, etc. corresponding to dikes and underground structures such as drainage of water and sewage, manholes, conduits, segments, pump stations, water purification plants, sewage treatment plants, railways, rivers, ports, etc. The field is quite wide.

As a well-known material for the index material, sodium bentonite index material and water-expandable rubber elastic index material are used.

The bentonite is mainly composed of natural inorganic clays obtained from underground ores, and the water-expandable rubber elastic index material is composed of specially modified rubber combining rubber and hydrophilic polymers (high performance polymer and bentonite).

The characteristics of the material as described above are excellent in durability, weather resistance, chemical resistance, unaffected by water quality and water temperature, excellent compressive capacity and water-proof function, easy to transport and handle, easy to install There is an advantage.

Due to the characteristics of the above materials, its function is to exponentially leak or submerge due to floating settlement by self-expanding action. After construction, it absorbs water in places where there are many leaks or floods and expands in underground structures. Gives the ability to expend a state permanently or with repeated expansion.

In view of the action of the index member, only the contact portion with water is expanded during volume expansion, and expansion due to moisture present in the concrete during concrete placement does not affect the cracking of the concrete due to expansion of the surface of the initial index member. The inflation force expands slowly over a period of more than 15 days after 24 hours and conversely contracts upon contraction (when fully submerged in water, drying at room temperature), or remains in an expanded state.

In addition, after the concrete is placed, the water inside the concrete expands and seals the voids in the concrete to block the inflow of water, so it is useful for self-sealing to catch cracks in the structure as well as the water. do.

As described above, the index member is installed on the floor, or, as described above, the shape of the index member is rolled in a roll shape so as to be convenient for use, and the index member 10 is attached to FIG. 1. As shown in the figure, embedding of the water repellent material is made as the casting of the concrete 2 in a state in which the predetermined point of the H-shaped steel 1 is wound.

For reference, the index member 10 applied to the H-beams (1) is to block the water coming up in the H-beams from the ground, which prevents the penetration of water from the inside of the wall, column portion of the structure Of course, it serves to protect the interior of the structure.

Conventional index member 10 applied to the H-shaped steel (1) is a product processed to a predetermined dimension with a set size of 4mm thickness, 20mm width, as shown in Figure 2 attached, one side of the It is a structure attached with a seal paper (P) for winding in the form of a roll to maintain the shape of the product.

The conventional index member having the structure as described above can be seen that the following problems appear during construction.

The use of the water repellent material is caused by the fact that the surface bonded to the H-beam (beam) or the pipe pipe has a significant drop in adhesive force, or the force that is generated before or after the concrete casting, when used in the H-beam steel pipe and the pipe pipe by its own adhesive force. Pressure) causes water leakage from H-beams or pipes.

In consideration of the easy separation of the water pipe from H-beams and pipes, the water-support support is welded to the H-beams and pipes.

This required a lot of time, cost and professional skills to take care of the poor construction of the index material or to install the index material support.

The use of the existing water repellent material is placed in a predetermined position of the H-shaped steel while temporarily removing the seal paper attached to one side in a rolled form. At this time, it can be temporarily attached by the degree of cohesion of the index material, but after a certain time there is a problem that the fall away from the H-shaped steel before concrete pouring due to the low cohesion.

Even if it is attached to the H-beam, the problem of falling of the index material is caused by the load of the concrete when it is being poured.In addition, when the concrete is poured in the expanded state, the concrete and the H-beam or the pipe are returned due to the return phenomenon. There was a problem in which a void occurs in the structure, or a leak occurs in the structure due to a hardening phenomenon that hardens after a long time.

In addition, even if concrete pouring is normally made in the state where the index member is attached to the H-beam, since the specification of the index member after the expansion of the index member is relatively small, about 4 mm thick and 20 mm wide, complete expansion occurs.

This means that in the curing of concrete, in the case of the index component containing the rubber component to be intact again, the index member wrapped in the H-shaped steel has a gap with the cured concrete, causing a problem of poor construction.

In addition to the conventional index material as described above, the clay index material made of bentonite can not be attached to the H-shaped steel because there is no point cohesion, it is more difficult to be placed on the index plate is applied to the joint portion of the structure.

In the case of the H-shaped steel and pipe pipe index using the conventional index material, a lot of time and cost is caused by installing a support for the index material (cutting the metal pieces and welding them in the form of wings according to the length and shape of the index material) have.

Therefore, the present invention has been devised to solve the conventional problems, and it is made of solid adhesive while complementing the flexibility and rigidity to the index material applied to H-shaped steel among concrete structures before concrete placement, and stable position fixing and contact with concrete materials. The purpose of this study is to limit the standard in consideration of the expansion index by the expansion index to prevent the full expansion of the index material due to the climate and concrete casting.

According to the present invention for achieving the above object, in the index material that is self-repairing the index, cracks are attached to the wall of the building structure, H-shaped steel to be embedded from the concrete, the index member has a thickness of 3 ~ 15mm, 30 It is manufactured in a width of ˜200 mm, and a net mesh (woven fabric) is attached to one side to complement flexibility and rigidity, and a double sided adhesive tape having an adhesive layer of a predetermined thickness is attached to the other side.

Hereinafter, with reference to the accompanying Figures 3 to 7 will be described in detail with respect to the present invention.

Figure 3 is a perspective view showing the index member 10 of the present invention, Figure 4 is a perspective view showing a state applied to the H-shaped steel 10 according to the present invention, Figure 5 is in accordance with the present invention It is a cross-sectional view of H-beams which shows the state where the water retardant 10 was applied.

The present invention is to be attached to the wall of the building structure, H-shaped steel (1) to be embedded from the concrete (2) in the index member 10 for self-repairing the index, cracks, the index member 10 is 3 ~ 15mm It is manufactured with a thickness of 30 ~ 200mm long, and one side is attached to the mesh 11 to complement the flexibility and rigidity, the other side is attached to the double-sided adhesive tape 12 having an adhesive layer of a predetermined thickness Structure.

The index member 10 is wound and rolled into a product, and the back surface of the separate seal paper attached to the double-sided adhesive tape 12 has a role in which the index member 10 is not wound in a roll shape as a whole. do.

The index member 10 is made of sodium bentonite or a water-expandable rubber elastic material.

In addition, Figure 6 is a side cross-sectional view showing an embodiment of an index member 10 according to the present invention, the nonwoven fabric 13 on the outer surface of the mesh 11 applied to one surface in the index member 10 ) May be further attached.

In the drawings, reference numeral 20 denotes an index plate.

Referring to the operation and effects according to the use of the index material 10 of the present invention having such a structure as follows.

First, in the index member 10 wound in the form of a roll, the adhesive layer is exposed when the seal paper of the double-sided adhesive tape 12 attached to one surface is exposed, and the adhesive layer is exposed as shown in FIG. It is attached to the predetermined position of (1).

The predetermined position of the H-beams 1 indicates a position lower than the floor upper surface where the concrete floor is formed from the floor surface on which the H-beams 1 are installed.

In the state as described above, the opposite side to which the double-sided adhesive tape 12 is attached is attached to the mesh 11, the index member 10 is flexibly attached to each predetermined portion along the shape of the H-shaped steel (1) is flexible Strong adhesion can be achieved while complementing the rigidity. As shown in FIG. 6 attached as an example, by attaching a nonwoven fabric 13 to the outer surface of the mesh 11, it is stably bent until it occurs in the shape maintenance and expansion of the commercialized index member 10 The flexibility of the can be given.

The index member 10 attached to the H-shaped steel 1 as the adhesive force of the double-sided adhesive tape 12 is firm and is not separated by the instantaneous self-weight of the concrete object 2 even when the concrete is poured to form a wall. The function of the ash 10 can be exhibited.

That is, the firm attachment of the index member (10) in the post-casting of concrete, maintains a stable state in the position change does not occur, which is leaked or submerged from the ground after curing of concrete H-shaped steel ( 1) In the state of riding up the characteristics of the index material 10 can exhibit the exponential function properly.

Attachment work of the index member 10 as described above can be carried out before the concrete is placed, the attachment work is simple yet very stable to improve the workability.

The index member 10 is a sodium bentonite material which is preferable for maintaining the shape according to the expanded state after expansion by contact with water, and the application of the double-sided adhesive tape 12 together with the mesh 11 is used to change the shape of the material. It is advantageous to attach while maintaining stable.

Alternatively, even in the case of the index member 10 of the water-expandable rubber-elastic material, the application of the mesh 11 and the double-sided adhesive tape 12 as described above occurs by placing or temporarily attaching only to the caking force of the rubber index member. It is possible to supplement the conventional problem.

In addition, as a feature of the above-mentioned water-repellent material 10, the standard is 3 ~ 15mm thick, 30-200mm width water-resistant material 10 is attached to the H-shaped steel 1, and then formwork (not shown in the figure) When the leakage occurs after the concrete pouring with the installation, the expansion occurs from the index member 10, wherein the above-described index member 10 installed on the concrete (2) to prevent the water pressure coming up by riding enough water And causes expansion of the H-shaped steel 1 or the index member 10 attached to the pipe.

At this time, since the specification of the index member 10 has a width and thickness of the margin compared to the specification of the conventional index member 10, the expansion of only the edge side due to the characteristics of the specification prevents the complete expansion early I can do it.

Therefore, the width of the index member 10 is preferably at least 30 mm or more.

This is, in the end, when the curing of the concrete is completed in the state of stably adhered index material 10, which can induce a secondary expansion when water infiltrates, this secondary expansion is H-shaped steel (1) and pipe pipe Self-Sealing for leaks coming up on the road to maintain a stable structure by preventing voids between the inside of the concrete structure and the water repellent material 10 during the evaporation of water as well as the exponent. It can be done.

Meanwhile, as shown in FIG. 7 attached to the H-shaped steel 1 in addition to the H-shaped steel 1, the index member 10 may be formed on the index plate 20 which is mostly used for the joint of the wall. After peeling off the seal paper, it is possible to secure the workability and the installation position of the stable index material 10 since the concrete material 2 can be poured together with the installation of the index plate in a state where the index material 10 is directly attached stably. .

As described above, the present invention is to form a water-resistant material for the waterproofing and self-repair of building structures with a thickness of 3 ~ 15mm, a width of 30 ~ 200mm, the attachment of the mesh on one side and the double-sided adhesive tape on the other side Alternatively, by attaching a double-sided adhesive tape with perforations, the water-resistant material at a stable position is prevented from being separated by the weight of the concrete before or during concrete pouring in a state where the water-resistant material is stably adhered from the H-shaped steel and the pipe pipe. It has the effect of exerting a function.

In addition, the index member of the present invention is a hassle to install a support (welded in the form of wings by cutting the metal pieces as the length and shape of the index member) for installation of the conventional index member applied to the H-shaped steel or pipe pipe. Not only can it cost a lot of cost, labor, and construction time, but it also delays expansion and hardens concrete by leaking when concrete is poured, so that water can be transported from below or above the H-beam through underground or underground. By completely blocking the penetration of water can be expected a certain effect of the exponential action.
