Description

Technology Field

[0001] The present invention relates to a unit for forming a leak-prevention type floor buffer structure, a floor structure for a multi-unit dwelling including the same, a multi-unit dwelling including the same, and a method for constructing a leak-prevention type floor buffer structure using the same.

[0002] In addition, the present invention relates to a joining method for preventing leakage in the connection of buffer members and wall connections. Background Technology

[0003] In general, in multi-unit dwellings such as apartments or villas, inter-floor noise occurs when impact sounds or various daily noises from upper-floor units are transmitted to lower-floor units through the inter-floor slab structure. When the level of such inter-floor noise is severe, it leads to disputes between upper and lower-floor units, causing serious social problems. Therefore, many measures are being proposed to resolve this inter-floor noise issue. Furthermore, according to the regulations on housing construction standards, each floor must satisfy a structure where both light impact sound (floor impact sound caused by relatively light and hard impacts) and heavyweight impact sound (floor impact sound caused by heavy and soft impacts) are 49 dB or less, so efforts are being made to reduce inter-floor noise.

[0004] Conventionally, to reduce inter-floor noise, noise-reducing flooring was installed between the inter-floor structure (slab) and the heating structure for installing floor hot water pipes. However, since it is difficult to reduce impact noise transmitted to the lower floor through the slab to 49 dB or less using only noise-reducing flooring, improvement measures are being prepared. To reduce inter-floor noise, a so-called 'floating floor structure' is applied, which creates a space of a certain height between the flooring and the slab. This allows some of the impact noise to be absorbed in the space between the flooring as it is transmitted from the flooring to the slab, thereby reducing inter-floor noise.

[0005] As a conventional example of a floor structure for multi-unit housing using such a 'floating floor structure,' the 'floor material for preventing inter-floor noise in multi-unit housing buildings' (hereinafter abbreviated as 'prior art') of Korean registered patent No. 10-2386315 is known. According to this prior art, an elastic member is installed between the lower panel of the floor material and the slab, which is an inter-floor structure. In addition, the 'building panel using a cushioning member' of Korean registered patent No. 10-2730719 is configured to be effective for sound insulation through the combination of various members.

[0006] The above-mentioned buffer member or buffer structure is installed, and mortar is filled on top to create a surface on which a finishing material can be installed. At this time, leakage is prevented by using taping or the like to prevent the mortar from penetrating the lower part of the mortar. However, there is a disadvantage in that the difficulty of construction increases to form this protective layer, and it is a vulnerable structure where construction defects may occur.

[0007] In other words, it is necessary to improve the joining methods of joints where leakage may occur due to mortar filling, such as joints between materials, connections, and vertical joints meeting walls. The problem to be solved

[0008] The present invention aims to solve the problems of the aforementioned conventional technology by providing a leak-prevention type floor buffer structure forming unit that simplifies the construction method for joining buffer structure members, facilitates quality maintenance for preventing defects, and does not rely on the worker's construction skills, a multi-unit housing floor structure including the same, a multi-unit housing including the same, and a method for constructing a leak-prevention type floor buffer structure using the same.

[0009] The present invention aims to solve the problems of the aforementioned conventional technology by providing a leak-prevention type floor cushioning structure forming unit capable of improving constructability and enhancing mortar leakage prevention performance by reducing the amount of work required for joint construction using existing tapes, a multi-unit housing floor structure including the same, a multi-unit housing including the same, and a method for constructing a leak-prevention type floor cushioning structure using the same.

[0010] However, the technical problems that the embodiments of the present invention aim to solve are not limited to the technical problems described above, and other technical problems may exist. means of solving the problem

[0011] As a technical means for achieving the above-mentioned technical problem, a leak-preventing floor cushioning structure forming unit according to the first aspect of the present invention comprises: a cushioning material installed on an inter-floor structure for floor impact sound reduction effect; and a film-shaped bonding material provided to have a width greater than that of the cushioning material in the horizontal direction, wherein an outer portion is formed by attaching a middle portion to the upper surface of the cushioning material and protruding further outward in the horizontal direction than that of the cushioning material, wherein the middle portion includes a central region in which a first bonding material is interposed between the cushioning material and the middle portion so as to be attached to the upper surface of the cushioning material with a first bonding force; and a perimeter region in which a second bonding material is interposed between the cushioning material and the middle portion so as to be attached to the upper surface of the cushioning material with a second bonding force lower than the first bonding force, and the perimeter region is a region forming the perimeter of the central region, wherein the second bonding material may be applied or attached to the lower surface of the outer portion of the bonding material.

[0012] In addition, the first bonding material may be an irreversible bonding material in which a curing bond is formed, and the second bonding material may be a reversible bonding material capable of re-bonding upon release of bonding.

[0013] In addition, the second bonding force can be set so that the perimeter area of ​​the bonding material can be released from the cushioning material when an external force is applied that causes the outer portion to be folded.

[0014] In addition, the perimeter area of ​​the above-mentioned binder can be bonded to the buffer material with a bonding force higher than the second bonding force due to the self-weight of the mortar filled on the above-mentioned binder.

[0015] In addition, the outer portion of the above-mentioned bonding material may be bonded to the upper surface of the outer portion of an adjacent leak-proof floor cushioning structure forming unit by means of a second bonding material applied or attached to its lower surface, or its upper surface may be bonded to the lower surface of the outer portion of the bonding material of the adjacent leak-proof floor cushioning structure forming unit by means of a second bonding material applied or attached to the lower surface of the outer portion of the bonding material of the adjacent leak-proof floor cushioning structure forming unit, thereby forming a bond between materials, or it may be folded and bonded in an L-shape to the wall surface of an adjacent wall to form a bond for a vertical joint meeting the wall.

[0016] In addition, the binder may be a waterproof film made of polypropylene or polyethylene.

[0017] Meanwhile, a multi-unit housing floor structure according to the second aspect of the present invention is a multi-unit housing floor structure comprising a leak-prevention type floor buffer structure forming unit according to the first aspect of the present invention, and may include an inter-floor structure; the leak-prevention type floor buffer structure forming unit installed on the inter-floor structure; and a mortar portion formed on the leak-prevention type floor buffer structure forming unit.

[0018] Meanwhile, a multi-unit dwelling according to the third aspect of the present invention may include a multi-unit dwelling floor structure according to the second aspect of the present invention.

[0019] Meanwhile, the method for constructing a leak-prevention type floor buffer structure according to the fourth aspect of the present invention is a method for constructing a leak-prevention type floor buffer structure using a leak-prevention type floor buffer structure forming unit according to the first aspect of the present invention, and may include: (a) a step of arranging a plurality of the leak-prevention type floor buffer structure forming units on the inter-floor structure; and (b) a step of filling mortar onto the plurality of the leak-prevention type floor buffer structure forming units to form a mortar portion.

[0020] Additionally, in step (b) above, the perimeter area of ​​the binder can be bonded to the buffer material with a bonding force higher than the second bonding force by the self-weight of the mortar filled on the binder.

[0021] Additionally, in step (a) above, the outer portion of the binder may be bonded to the upper surface of the outer portion of an adjacent leak-proof floor cushioning structure forming unit by means of a second bonding material applied or attached to its lower surface, or its upper surface may be bonded to the lower surface of the outer portion of the binder of the adjacent leak-proof floor cushioning structure forming unit by means of a second bonding material applied or attached to the lower surface of the outer portion of the binder of the adjacent leak-proof floor cushioning structure forming unit, thereby forming a bond between materials, or it may be folded and bonded in an L shape to the wall surface of an adjacent wall to form a bond for a vertical joint meeting the wall.

[0022] In addition, in step (b) above, due to the self-weight of the mortar filled on the binder, the bonding between the materials or the bonding to the vertical joint may be formed with a bonding force higher than the second bonding force.

[0023] In addition, in step (a) above, to reinforce the connection for the vertical joint, one or more additional reinforcements among tape, sealing material, and mechanical fasteners may be performed at the end of the outer portion that is folded and joined in the L shape.

[0024] The means for solving the problem described above are merely exemplary and should not be interpreted as intended to limit the present invention. In addition to the exemplary embodiments described above, additional embodiments may exist in the drawings and the detailed description of the invention. Effects of the invention

[0025] According to the solution to the problem of the present invention described above, a film-shaped bonding material is provided on the upper surface of a cushioning material, having an intermediate part and an outer part divided into a central area having a first bonding force and a perimeter area having a second bonding force. This makes bonding between materials easier than in conventional methods, thereby enabling improved construction performance and providing the effect of guaranteeing quality simply by verifying the accurate installation of the material without relying on the worker's construction skills.

[0026] According to the means for solving the problem of the present invention described above, by utilizing the irreversible first bonding material, the reversible second bonding material, and the self-weight of the mortar to increase the bonding strength, bonding between materials is achieved solely through the overlapping and folding of the bonding material without the need for separate adhesive materials such as tape, thereby reducing the amount of work required for conventional taping construction and improving the performance of preventing mortar leakage.

[0027] However, the effects obtainable from this invention are not limited to those described above, and other effects may exist. Brief explanation of the drawing

However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. Furthermore, in order to clearly explain the present invention in the drawings, parts unrelated to the explanation have been omitted, and similar parts throughout the specification are denoted by similar reference numerals.

[0032] Throughout this specification, when a part is described as "comprising" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0033] The present invention relates to a unit for forming a leak-prevention type floor buffer structure, a floor structure for a multi-unit dwelling including the same, a multi-unit dwelling including the same, and a method for constructing a leak-prevention type floor buffer structure using the same.

[0034] In addition, the present invention relates to a joining method for preventing leakage in the connection of buffer members and wall connections.

[0035] In addition, the present invention relates to a joining method installed at the joint between cushioning members and at the vertical joint meeting with a wall, and to a material composition and cushioning structure suitable for the same. In particular, when installing a cushioning structure for reducing inter-floor noise in multi-unit dwellings such as apartments or villas, the joints between materials are taped to prevent leakage of the mortar filled on top; the invention relates to a joining method and a material composition plan necessary for the same to replace this method and to prevent defects and improve quality performance.

[0036] Hereinafter, a leak-prevention type floor cushioning structure forming unit according to the first aspect of the present invention (hereinafter referred to as the 'the floor cushioning structure forming unit (100)') will be described.

[0037] FIG. 1 is a drawing for explaining a leak-prevention type floor cushioning structure forming unit according to one embodiment according to the first aspect of the present invention.

[0038] Specifically, FIG. 1 is a cross-sectional view of a cushioning structure forming unit (100) in which a cushioning material (110) and a bonding material (120) are combined according to the first aspect of the present invention.

[0039] Referring to FIG. 1, the cushioning structure forming unit (100) may include a cushioning material (110) installed on an inter-floor structure (200) for floor impact sound reduction effect.

[0040] Specifically, the cushioning material (110) is a component installed on the inter-floor structure (200) for floor impact sound reduction effects, and may be a component for reducing inter-floor noise transmitted to the lower floor unit through the slab, which is the inter-floor structure, from impact sound or various living noises applied from the upper floor unit. However, since the cushioning material (110) is a component obvious to a person skilled in the art, a more detailed description will be omitted.

[0041] Additionally, referring to FIG. 1, the cushioning structure forming unit (100) may include a film-shaped bonding material (120) having a width greater than that of the cushioning material (110) in the horizontal direction, and an outer portion (122) formed by attaching an intermediate portion (121) to the upper surface of the cushioning material (110) and protruding further outward in the horizontal direction than the cushioning material (110).

[0042] Specifically, referring to FIG. 1, the bonding material (120) may be provided to have a width greater than that of the cushioning material (110) in the horizontal direction, so as to cover the upper surface of the cushioning material (110) and simultaneously extend further than the outer portion of the cushioning material (110).

[0043] That is, the binder (120) may be provided in the form of a film in which an intermediate portion (121) is attached to the upper surface of the cushioning material (110) and an outer portion (122) is formed that protrudes further outward in the horizontal direction than the cushioning material (110).

[0044] Additionally, the width of the outer portion (122) can be set considering the connection (connection between materials) with the adjacent leak-proof floor cushioning structure forming unit (100') to be described later and the connection at the vertical joint (8) with the wall (9). Specifically, the width of the outer portion (122) can be set such that the second adhesive member can exert sufficient bonding force during the connection between materials and the connection at the vertical joint (8).

[0045] In addition, the term "film form" here may refer to a thin and flexible sheet form capable of performing both waterproofing and adhesive functions simultaneously.

[0046] Specifically, the binder (120) may be a waterproof film made of polypropylene (PP) or polyethylene (PE). However, the material setting of the binder (120) is not limited to this and may be set to various waterproof materials.

[0047] FIG. 2 is a drawing for explaining the central area and the perimeter area in the first aspect of the present invention.

[0048] Specifically, FIG. 2 is a plan view of the cushioning structure forming unit (100) in which a cushioning material (110) and a bonding material (120) are combined according to the first aspect of the present invention.

[0049] Specifically, referring to FIGS. 1 and FIGS. 2, the middle portion (121) may include a central portion (121a) which is a region in which a first bonding material is interposed between the buffer material (110) and the buffer material (110) so as to be attached to the upper surface of the buffer material (110) with a first bonding force.

[0050] Here, the first bonding material may be an irreversible bonding material in which a curing bond is formed. For example, the first bonding material may be an adhesive material such as a bond.

[0051] That is, referring to Fig. 1 (b) and Fig. 2 (b), the central region (121a) can be described as a complete joint. Here, "complete joint" can be understood to mean a level of joint that prevents separation between the cushioning material (110) and the bonding material (120) during the construction of a residential building, from the perspective of a standard of joint strength that is obvious to a person skilled in the art.

[0052] Additionally, referring to FIGS. 1 and 2, the middle portion (121) is an area in which a second bonding material is interposed between the buffer material (110) and the buffer material (110) so as to be attached to the upper surface of the buffer material (110) with a second bonding force lower than the first bonding force, and may include a perimeter area (121b) which is an area forming the perimeter of the central area (121a).

[0053] Referring to FIGS. 1 and 2, the perimeter region (121b) is a region attached to the upper surface of the cushioning material (110) with a second bonding force lower than the first bonding force, and may be a region forming the perimeter of the center region (121a).

[0054] Here, the second bonding material may be a reversible bonding material capable of re-bonding upon bond release.

[0055] For example, the second bonding material may be an adhesive material such as an adhesive or double-sided tape, or a reversible adhesive material. As a more specific example, the second bonding material may be an adhesive material applied to the back of a Post-it note, but is not limited thereto; it may be various bonding materials capable of maintaining a predetermined bonding strength range that allows for re-bonding as long as foreign substances are not attached upon release.

[0056] Additionally, referring to Fig. 1(b) and Fig. 2(b), the perimeter region (121b) can be described as a semi-joined portion joined with a lower joining force than a full joint.

[0057] Here, semi-bonding can refer to a reversible bond in which a predetermined bonding strength can be maintained even after being detached and reattached multiple times, as long as foreign substances do not adhere; therefore, it may have a lower bonding strength than a full bond.

[0058] That is, the bonding material (120) may include a fully bonded (bonded) part and a partially bonded part. At this time, the fully bonded (bonded) part is a part that is bonded to the bonding material (120) and the buffer material (110), and may be provided to be fully bonded so that separation between the buffer material (110) and the bonding material (120) does not occur. In addition, the partially bonded part has a second bonding material applied to the lower part of the bonding material (120) and the upper part of the buffer material (110) to have a second adhesive force, and the part that does not overlap with the buffer material (110) may be bonded when bonded with another buffer structure.

[0059] In addition, the cushioning structure forming unit (100) can change the bonding area or method between the bonding material (120) and the cushioning material (110) (cushioning member) to match the form of the cushioning structure by changing the type of adhesive applied or attached to the lower part of the bonding material (120).

[0060] FIG. 3 is a drawing illustrating the operating range of a binder in the first aspect of the present invention.

[0061] Specifically, FIG. 3 is a drawing for explaining the operating range of a buffer structure forming unit (100) (buffer structure) (specifically a binder (120)) viewed from the first aspect of the present invention.

[0062] More specifically, referring to FIG. 3, the second bonding force can be set so that the perimeter area (121b) of the bonding material (120) can be released from the cushioning material (110) when an external force is applied that causes the outer portion (122) to be film-folded.

[0063] In other words, referring to FIG. 3, the perimeter area (121b) of the bonding material (120) is released from the cushioning material (110) when an external force for film folding is applied to the outer part (122), so that the outer part (122) can be freely folded or bent. This makes bonding between materials easier than in conventional methods.

[0064] Here, the external force action that causes the film to fold may mean a force action applied from the outside (directly by a person, or from an adjacent unit during the process of arranging adjacent units) to cause the film-shaped binder (120) to bend or fold in an out-of-plane direction rather than in the direction of the film surface.

[0065] That is, film folding means that the bonding material (120) is bent or folded out of plane in a flat state, and through the bending or folding of the outer part (122) out of plane, the outer part (122) may be able to be joined to the vertical joint (8) that meets the wall (9) and the joining of materials to be described later.

[0066] At this time, the aforementioned first bonding force can be set to prevent the detachment of the central region (121a) of the bonding material (120) from the cushioning material (110) when an external force is applied to cause the outer part (122) to be folded.

[0067] Through this, when an external force for film folding is applied to the outer portion (122), the central region (121a) where the first bonding force is formed, as shown in FIG. 3, does not detach from the cushioning material (110), and the bonding material (120) (specifically the outer portion (122) and the perimeter region (121b)) can be bent or folded out of plane.

[0068] That is, by utilizing a material such as PP film that can prevent leakage while ensuring a certain strength, the binder (120) can prevent leakage of mortar, etc. poured on the upper part of the floor cushioning structure forming unit (100) (cushioning structure) as it overlaps, and can secure flexibility through folding construction at the vertical joint with the wall.

[0069] In addition, the floor cushioning structure forming unit (100) can adjust the constructability and adhesion strength by adjusting the bonding strength between the lower part of the bonding material (120) and the upper part of the cushioning material (110) in each section.

[0070] Additionally, the perimeter area (121b) of the binder (120) can be bonded to the cushioning material (110) with a bonding force higher than the second bonding force due to the self-weight of the mortar filled on the binder (120).

[0071] In other words, during the initial construction phase, the perimeter area (121b) maintains a reversible bonded state with a second bonding force, but after the mortar is filled, the bonding force increases beyond the second bonding force due to the weight of the mortar, thereby forming a more solid bonded state.

[0072] Additionally, a second bonding material may be applied or attached to the lower surface of the outer portion (122) of the bonding material (120).

[0073] Specifically, referring to FIG. 1(b) and FIG. 2(b), the lower surface of the outer portion (122) may be coated or attached with a second bonding material and maintained in a state not bonded to the cushioning material (110). That is, the unbonded area shown in FIG. 1(b) and FIG. 2(b) may mean an area that is not bonded to the cushioning material (110) while the second bonding material is coated or attached.

[0074] FIGS. 4 and 5 are drawings for explaining that, in the first aspect of the present invention, a binder comes into contact with a binder of an adjacent leak-proof floor cushioning structure forming unit.

[0075] Specifically, FIGS. 4 and 5 are drawings for explaining an example of the combination of a buffer structure forming unit (100) (buffer structure) (specifically a binder (120)) as seen in the first aspect of the present invention.

[0076] Figure 6 is a drawing illustrating the conventional cushioning structure combination and wall connection joint.

[0077] Additionally, referring to FIGS. 4 and 5, the outer portion (122) of the bonding material (120) may be bonded to the upper surface of the outer portion (122) of the adjacent leak-proof floor cushioning structure forming unit (100') by means of a second bonding material applied or attached to its lower surface, or the upper surface may be bonded to the lower surface of the outer portion (122) of the bonding material (120) of the adjacent leak-proof floor cushioning structure forming unit (100') by means of a second bonding material applied or attached to its lower surface, thereby forming a bond between the materials.

[0078] Here, the combination of materials may mean that the floor cushioning structure forming unit (100) and the adjacent leak-proof floor cushioning structure forming unit (100') are combined as shown in FIG. 4.

[0079] Specifically, referring to FIG. 3, when an external force is applied to the outer portion (122') of the bonding material (120') of an adjacent leak-proof floor cushioning structure forming unit (100'), the perimeter area of ​​the adjacent leak-proof floor cushioning structure forming unit (100') is released from the bonding material (110), and as shown in FIG. 3, the perimeter area and outer portion (122') of the adjacent leak-proof floor cushioning structure forming unit (100') can be film-folded.

[0080] In addition, when an external force is applied to each outer portion (122) of the bonding material (120) of the floor cushioning structure forming unit (100) in the same manner to cause the film to fold, the perimeter area (121b) of the floor cushioning structure forming unit (100) is released from the bonding material (110), and as shown in FIG. 3, the perimeter area (121b) and the outer portion (122) of the floor cushioning structure forming unit (100) can be film folded.

[0081] At this time, referring to FIG. 4, the perimeter area (121b) and outer part (122') of an adjacent leak-preventing floor cushioning structure forming unit (100') are inserted between the film-folded perimeter area (121b) and outer part (122) and the cushioning material (110) in the upper direction (12 o'clock direction based on FIG. 4), and through a second bonding material applied or attached to the lower surface of the perimeter area (121b) and outer part (122), the lower surface of the perimeter area (121b) and outer part (122) is bonded to the upper surface of the perimeter area and outer part (122') of the adjacent leak-preventing floor cushioning structure forming unit (100'), thereby forming a bond between the materials.

[0082] As another example, the perimeter area (121b) and outer part (122) are inserted between the perimeter area and outer part (122') of an adjacent leak-proof floor cushioning structure forming unit (100') that is film-folded in the upper direction (12 o'clock direction based on FIG. 4) and the cushioning material (110') of the adjacent leak-proof floor cushioning structure forming unit (100'), and the upper surface of the perimeter area (121b) and outer part (122) is bonded to the lower surface of the outer part (122) of the bonding material (120) of the adjacent leak-proof floor cushioning structure forming unit (100') through a second bonding material applied or attached to the lower surface of the perimeter area and outer part (122') of the adjacent leak-proof floor cushioning structure forming unit (100'), thereby forming a bond between the materials.

[0083] That is, the floor cushioning structure forming unit (100) can be joined by utilizing the overlap and folding of the bonding material (120) without the need for a separate adhesive material such as tape when joining materials (when connecting cushioning members). At this time, the joining area can form a bonding and waterproof layer based on the weight of the mortar filled on the upper part of the floor cushioning structure forming unit (100) itself, based on the overlap and waterproofing.

[0084] In this regard, conventional methods utilize tape for mortar leakage prevention construction to bond materials, as illustrated in Fig. 6. However, this construction method requires that the bonding area between materials be in a state where tape can be easily attached or that the surface be smooth. Even if these material requirements are met, if dust or foreign matter is present in the construction site environment, the adhesive strength cannot be maintained through taping, leading to damage or detachment of the bond after construction. Therefore, to resolve this, maintaining the construction site environment and requiring additional effort from the worker are necessary. This additional effort hinders workability, and a problem has arisen where quality is determined by the skill level of the worker.

[0085] In other words, conventional methods of joining materials using tape adhesion had problems such as difficulty in adhesion due to dust or poor surface conditions, and easy detachment.

[0086] Meanwhile, referring to FIGS. 4 and 5, as described above, the floor cushioning structure forming unit (100) can form a stable bond between materials without a separate tape through a reversible bonding using a second bonding material and a film folding mechanism, thereby improving constructability and quality at the same time.

[0087] Specifically, referring to FIGS. 4 and 5, the formation of a bond between materials through the outer portion (122) of the binder (120) can improve constructability and prevent mortar leakage by reducing the amount of work required for joint construction using conventional tape as shown in FIG. 6.

[0088] In other words, the floor cushioning structure forming unit (100) can form a stable bond between materials without additional effort such as surface treatment for tape attachment or construction site environment management that was previously required, thereby solving the problem where quality is determined by the skill level of the worker.

[0089] In addition, the floor cushioning structure forming unit (100) is not affected by dust or foreign substances due to the construction site environment when joining materials, unlike the conventional tape attachment method, and does not depend on the level of construction skills of the worker.

[0090] That is, the floor cushioning structure forming unit (100) can increase installation work efficiency by replacing the taping work between existing materials and the connection part meeting the wall, and can improve quality by preventing mortar from penetrating into the connection part due to impact after taping work and insufficient taping support strength, and by preventing leakage.

[0091] Additionally, referring to FIG. 5, the outer portion (122) of the bonding material (120) can be folded and joined in an L shape to the wall surface (9a) of an adjacent wall (9) to form a connection to the vertical joint (8) that meets the wall (9).

[0092] Specifically, referring to FIG. 3, when an external force is applied to the outer portion (122) of the bonding material (120) of the floor cushioning structure forming unit (100) to cause the film to fold, the bonding of the perimeter area (121b) is released and folded into an L shape, thereby forming a bond at the vertical joint (8) that meets the wall (9). Through this, mortar leakage that may occur at the vertical joint (8) where the floor material of the cushioning structure meets the wall (9) can be effectively prevented.

[0093] In this regard, to explain the conventional technology, as shown in Fig. 6, conventional vertical joints required the joining (bonding) of dissimilar materials, necessitating the installation of an 'L'-shaped tape fold using tape. This method of installation is affected by the installer's skill, making it difficult to maintain quality. Furthermore, there was a problem where the attached tape detached due to the movement of the worker or load during mortar pouring after the installation of the flooring material, causing defects where mortar flowed in through the detached parts.

[0094] Meanwhile, the floor cushioning structure forming unit (100) can simultaneously secure ease of construction and leak prevention performance by replacing the bonding method using tape through an L-shaped folded bonding structure using the outer part (122) of the bonding material (120).

[0095] At this time, if necessary, a finishing treatment utilizing an additional reinforcement method may be performed at the end of the semi-joint portion of the bonding material (120) to reinforce the vertical joint portion (8) joined to the wall (9). In other words, if necessary, one or more additional reinforcements among tape, sealing material, and mechanical fasteners may be performed at the end of the outer portion (122) that is folded and joined in an L shape. For example, in the case of reinforcement using a sealing material, a silicone-based or urethane-based sealing material may be used, and in the case of a mechanical fastener, staples, nails, screws, etc. may be used.

[0096] That is, the binder (120) can be provided with a material that forms a film-shaped membrane (polypropylene (PP), polyethylene (PE), etc.) and can be adhered to the cushioning material (110) (upper part of the cushioning structure). At this time, by dividing the bonding area of ​​the binder (120) to the cushioning material (110) (upper part of the cushioning structure) and setting different bonding strengths, the bonding part and vertical joint (8) formed between the materials can be sealed without leakage.

[0097] In other words, the floor cushioning structure forming unit (100) has a simple construction method for joining each cushioning structure member, easy quality maintenance to prevent defects, and can guarantee quality by verifying the accurate installation of materials without relying on the worker's construction skills. In addition, the floor cushioning structure forming unit (100) can reduce the amount of work required for joint construction using conventional tape and improve mortar leakage prevention performance.

[0098] Hereinafter, a floor structure for a multi-unit dwelling according to the second aspect of the present invention (hereinafter referred to as "the floor structure for a multi-unit dwelling (1000)") will be described. However, the floor structure for a multi-unit dwelling (1000) is a floor structure for a multi-unit dwelling that includes the cushioning structure forming unit (100), and since it shares the same or corresponding technical features with the cushioning structure forming unit (100), the same reference numerals will be used for configurations that are identical or similar to the configuration of the cushioning structure forming unit (100), and redundant descriptions will be simplified or omitted.

[0099] Referring to FIG. 5, the floor structure (1000) of the multi-unit dwelling may include an inter-floor structure (200).

[0100] The inter-floor structure (200) is generally a structure that separates floors in a multi-unit dwelling and may include a slab, etc. However, since the inter-floor structure (200) is a configuration obvious to a person skilled in the art, a more detailed description will be omitted.

[0101] Additionally, referring to FIG. 5, the floor structure (1000) of the multi-unit dwelling may include a buffer structure forming unit (100) installed on a floor structure (200).

[0102] Specifically, the inter-floor structure (200) is a structure that serves as a path for impact noise or various living noises applied from the upper floor to be transmitted to the lower floor, and a buffer structure forming unit (100) can be installed on the upper part thereto to block the transmission of inter-floor noise.

[0103] At this time, referring to FIG. 1, the cushioning structure forming unit (100) may include a cushioning material (110) installed on the inter-floor structure (200) for floor impact sound reduction effect.

[0104] Additionally, referring to FIG. 1, the cushioning structure forming unit (100) may include a film-shaped bonding material (120) having a width greater than that of the cushioning material (110) in the horizontal direction, and an outer portion (122) formed by attaching an intermediate portion (121) to the upper surface of the cushioning material (110) and protruding further outward in the horizontal direction than the cushioning material (110).

[0105] Specifically, the binder (120) may be a waterproof film made of polypropylene or polyethylene.

[0106] Specifically, referring to FIGS. 1 and 2, the middle portion (121) may include a central portion (121a) which is a region in which a first bonding material is interposed between the buffer material (110) and the buffer material (110) so as to be attached to the upper surface of the buffer material (110) with a first bonding force. Here, the first bonding material may be an irreversible bonding material in which a curing bond is formed.

[0107] Additionally, referring to FIGS. 1 and 2, the middle portion (121) is a region in which a second bonding material is interposed between the buffer material (110) and the buffer material (110) so as to be attached to the upper surface of the buffer material (110) with a second bonding force lower than the first bonding force, and may include a perimeter region (121b) which is a region forming the perimeter of the central region (121a). Here, the second bonding material may be a reversible bonding material capable of re-bonding upon release.

[0108] More specifically, referring to FIG. 3, the second bonding force can be set so that the perimeter area (121b) of the bonding material (120) can be released from the cushioning material (110) when an external force is applied that causes the outer portion (122) to be film-folded.

[0109] Additionally, the perimeter area (121b) of the binder (120) can be bonded to the cushioning material (110) with a bonding force higher than the second bonding force due to the self-weight of the mortar in the mortar portion to be described later, which is filled on the binder (120).

[0110] Additionally, a second bonding material may be applied or attached to the lower surface of the outer portion (122) of the bonding material (120).

[0111] Additionally, referring to FIGS. 4 and 5, the outer portion (122) of the bonding material (120) may be bonded to the upper surface of the outer portion (122) of the adjacent leak-proof floor cushioning structure forming unit (100') by means of a second bonding material applied or attached to its lower surface, or the upper surface may be bonded to the lower surface of the outer portion (122) of the bonding material (120) of the adjacent leak-proof floor cushioning structure forming unit (100') by means of a second bonding material applied or attached to its lower surface, thereby forming a bond between the materials.

[0112] Additionally, referring to FIG. 5, the outer portion (122) of the bonding material (120) can be folded and joined in an L shape to the wall surface (9a) of an adjacent wall (9) to form a connection to the vertical joint (8) that meets the wall (9).

[0113] In addition, the floor structure (1000) of the multi-unit dwelling may include a mortar portion formed on the buffer structure forming unit (100).

[0114] At this time, as described above, the perimeter area (121b) of the binder (120) can be bonded to the buffer material (110) with a bonding force higher than the second bonding force by the mortar part. Leakage can be prevented through the bonding between the mortar part and the materials of the binder (120) of the buffer structure forming unit (100) described above, and through the bonding to the vertical joint (8). As such, the mortar part is organically linked with the binder (121b) to bring about a synergistic effect that further increases the bonding force and further prevents leakage; however, since the mortar part itself corresponds to a configuration obvious to a person skilled in the art, a more detailed explanation will be omitted.

[0115] Meanwhile, the present invention may provide a multi-unit dwelling according to the third aspect of the present invention. The above multi-unit dwelling is a multi-unit dwelling comprising the floor structure (1000) of the present multi-unit dwelling. However, since the description of the floor structure (1000) of the present multi-unit dwelling has been previously described, a more detailed description will be omitted.

[0116] Here, multi-unit housing may include apartments and multi-family houses (villas), etc. Specifically, multi-unit housing may refer to residential facilities with a multi-story structure where inter-floor noise issues may occur.

[0117] Hereinafter, a method for constructing a leak-prevention type floor cushioning structure according to the fourth aspect of the present invention (hereinafter referred to as the ‘this construction method (S)’) will be described. However, since this construction method (S) is a method for constructing a leak-prevention type floor cushioning structure using the cushioning structure forming unit (100), and shares the same or corresponding technical features with the cushioning structure forming unit (100), the same reference numerals will be used for configurations that are identical or similar to the configuration of the cushioning structure forming unit (100), and redundant descriptions will be simplified or omitted.

[0118] FIG. 7 is a simplified flowchart of a method for constructing a leak-proof floor cushioning structure using a leak-proof floor cushioning structure forming unit according to the fourth aspect of the present invention.

[0119] Referring to FIG. 7, the construction method (S) may include a step (step S1) of placing a plurality of buffer structure forming units (100) on an interlayer structure (200).

[0120] In step S1, a plurality of buffer structure forming units (100) can be placed on the interlayer structure (200).

[0121] At this time, a plurality of main buffer structure forming units (100) are arranged at a predetermined interval, and their positions can be set so that the outer portions (122) between adjacent units can be overlapped and joined.

[0122] In addition, for the buffer structure forming unit (100) placed near the wall (9), it is preferable to place it with an appropriate amount of clearance so that the outer part (122) can be folded in an L-shape on the wall surface (9a).

[0123] However, since the description of the buffer structure forming unit (100) has been previously described, a more detailed description will be omitted.

[0124] At this time, referring to FIG. 5, in step S1, the outer portion (122) of the binder (120) may be bonded to the upper surface of the outer portion (122) of the adjacent leak-proof floor cushioning structure forming unit (100') by means of a second bonding material applied or attached to its lower surface, or the upper surface may be bonded to the lower surface of the outer portion (122) of the binder (120) of the adjacent leak-proof floor cushioning structure forming unit (100') by means of a second bonding material applied or attached to its lower surface, thereby forming a bond between the materials.

[0125] At this time, the second bonding force is set so that when an external force is applied to cause the outer portion (122) to be film-folded, the perimeter area (121b) of the bonding material (120) can be released from the cushioning material (110). When an external force is applied to cause the film to be film-folded in step S1, the perimeter area (121b) of the bonding material (120) is released from the cushioning material (110), and the bonding material (120) is film-folded so that a bond between materials can be formed.

[0126] However, since the process of combining materials with the adjacent leak-prevention type floor cushioning structure forming unit (100') has been described above, a more detailed explanation will be omitted.

[0127] Additionally, referring to FIG. 5, in step S1, the outer portion (122) of the bonding material (120) is folded and joined in an L shape to the wall surface (9a) of the adjacent wall (9), thereby forming a connection to the vertical joint (8) that meets the wall (9).

[0128] At this time, the second bonding force is set so that when an external force is applied to cause the outer portion (122) to be film-folded, the perimeter area (121b) of the bonding material (120) can be released from the cushioning material (110). When an external force is applied to cause the film to be film-folded in step S1, the perimeter area (121b) of the bonding material (120) is released from the cushioning material (110), and the bonding material (120) is film-folded so that a bond can be formed for the vertical joint portion (8).

[0129] However, since the process of joining the vertical joint (8) has been described above, a more detailed explanation will be omitted.

[0130] At this time, in step S1, to reinforce the connection for the vertical joint (8), one or more additional reinforcements of tape, sealing material, and mechanical fasteners may be performed at the end of the outer part (122) that is folded and joined in an L shape.

[0131] That is, in the S1 stage, additional reinforcement can further improve the reliability of the connection at the vertical joint (8) meeting the wall (9). In addition, even when tape is used, unlike conventional tape joining methods, it is used only in an auxiliary role, so the difficulty of construction can be significantly reduced. For example, in the case of reinforcement using a sealant, silicone-based or urethane-based sealants may be used, and in the case of mechanical fasteners, staples, nails, screws, etc. may be used.

[0132] In other words, in the S1 stage, a finishing treatment utilizing an additional reinforcement method can be performed at the end of the semi-joint of the bonding material (120) to reinforce the vertical joint (8) joined to the wall (9).

[0133] Additionally, referring to FIG. 7, the construction method (S) may include a step (S2) of forming a mortar section by filling a plurality of buffer structure forming units (100) with mortar.

[0134] In step S2, mortar may be filled onto multiple buffer structure forming units (100) to form a mortar section. However, since the process of filling with mortar to form a mortar section is obvious to a person skilled in the art, a more detailed explanation will be omitted.

[0135] At this time, in step S2, the perimeter region (121b) of the binder (120) can be bonded to the cushioning material (110) with a bonding force higher than the second bonding force due to the self-weight of the mortar filled on the binder (120).

[0136] In other words, in the S1 stage before the mortar portion is formed, the perimeter area (121b) can maintain a reversible bonded state with a second bonding force. Through this, an external force is applied to cause the film to fold when the outer portion (122) of the binder (120) is bonded to the material and to the vertical joint (8), thereby enabling the film folding of the outer portion (122) and enabling the bonding of the outer portion (122) to the material and to the vertical joint (8).

[0137] At this time, after the joining of materials in the outer part (122) and the joining of the vertical joint (8) is completed, mortar is filled onto a plurality of the buffer structure forming units (100) in step S2 to form a mortar section, and due to the weight of the filled mortar, the part of the perimeter area (121b) of the bonding material (120) where the joining of materials in the outer part (122) and the joining of the vertical joint (8) are not performed can be joined to the buffer material (110) with the joining force increased to the second joining force.

[0138] Additionally, in step S2, due to the self-weight of the mortar filled on the binder (120), the bonding between materials or the bonding to the vertical joint (8) can be achieved with a bonding force higher than the second bonding force.

[0139] In other words, in the S1 stage before the mortar portion is formed, the perimeter area (121b) can maintain a reversible bonded state with a second bonding force. Through this, an external force is applied to cause the film to fold when the outer portion (122) of the binder (120) is bonded to the material and to the vertical joint (8), thereby enabling the film folding of the outer portion (122) and enabling the bonding of the outer portion (122) to the material and to the vertical joint (8).

[0140] At this time, after the joining of materials in the outer part (122) and the joining of the vertical joint (8) are completed, in step S2, mortar is filled onto a plurality of the buffer structure forming units (100) to form a mortar section, and the bonding force of the outer part (122) can be increased above the second bonding force due to the weight of the filled mortar. Through this, the joining of materials or the joining of the vertical joint (8) can be achieved with a bonding force higher than the second bonding force.

[0141] Through this, the present method (S) can increase installation work efficiency by replacing the taping work between existing materials and the connection where it meets the wall. In addition, the present method (S) can improve quality by preventing mortar from penetrating the connection due to detachment caused by impact after taping and insufficient taping support, and by preventing leakage.

[0142] In other words, the present method (S) relates to the combination of materials used to form a floor cushioning structure installed for floor impact sound reduction effects, and the method of joining between the cushioning structure and building structures such as walls. By presenting a material composition diagram, the joining of materials becomes easier than with existing methods, thereby enabling improved construction performance and preventing the risk of reduced adhesion strength and detachment that may occur during joining, thus allowing the floor impact sound reduction performance to be fully achieved.

[0143] In other words, the present method (S) can be combined to prevent leakage and mortar intrusion between the connecting parts of the materials and the connecting parts that meet the wall when installing the cushioning structure forming unit (100) for reducing floor impact sound, and can prevent defects and incorrect construction that impede the floor impact sound reduction effect by sealing the connecting parts between the materials and the connecting parts that meet the wall.

[0144] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will understand that other specific forms can be easily modified without altering the technical concept or essential features of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, each component described as a single unit may be implemented in a distributed manner, and components described as distributed may likewise be implemented in a combined form.

[0145] The scope of the present invention is defined by the claims set forth below rather than by the detailed description above, and all modifications or variations derived from the meaning and scope of the claims and the concept of equivalents thereof should be interpreted as being included within the scope of the present invention.
