Description

DRY CONSTRUCTION FLOOR STRUCTURE OF BUILDINGS

The description below is about the dry construction floor structure of a building.

The floor of a building is equipped with boiler pipes for heating and various insulating materials. One of the methods for constructing a floor of a building is the wet construction method, which places liquefied concrete on the floor of the building, installs various materials, and then cures them. This wet construction method allows for quick construction, but requires environmental conditions suitable for construction (e.g. temperature, season, etc.), and there are many restrictions on changing the structure inside the building. On the other hand, in the case of the dry construction method, various materials that make up the floor are installed sequentially on the slab. In the case of the dry construction method, although construction is more complicated than the wet construction method, it has the advantage of being less affected by the surrounding environment and being able to flexibly change the structure in response to changes in the structure inside the building.

Meanwhile, in the case of buildings such as intelligent buildings equipped with office automation facilities, free changes in internal space are required according to the user's usage environment, and wiring such as wires and communication lines used in various electric/electronic devices need to be freely arranged. Recently, in order to achieve this freedom of wiring, fluo panels installed at a certain distance from the floor surface (e.g. slab) of the building have been widely used.

The floor panel is not supported at four points by the support beam, but is supported in a way that some of it is fixed to the wall surface. This reduces the durability of the floor panel assembly and may generate noise due to vibration of the floor panel.

The background technology described above is technology that the inventor possessed or acquired in the process of deriving the disclosure content of the present application, and cannot necessarily be said to be a publicly known technology disclosed to the general public prior to the present application.

Referring to FIGS. 1 to 6, a dry floor construction structure according to an embodiment may be applied to a floor surface of a building. For example, the dry floor construction structure may be applied to an upper portion of a slab (S) constituting each floor of a building, thereby forming an interior floor of the building. In an embodiment, the dry floor construction structure (hereinafter referred to as “construction structure”) may be applied to an interior floor of a building through a dry construction method. The construction structure may form an interior floor of a building by sequentially assembling a plurality of building materials. In an embodiment, the construction structure may be constructed in a structure that reduces noise between each floor of the building. In an embodiment, the construction structure may form a space in which various electric/electronic device wires, communication lines, and heating pipes are installed on the floor of the building.

In one embodiment, the construction structure may include a vibration-proof pad (110), a panel support (123)(120), an insulation panel (130), a floor panel (140), a pipe support panel (160), a lower buffer plate (151), an upper buffer plate (152), a steel plate panel (170), and a finishing panel (180). Hereinafter, for convenience of explanation, a direction perpendicular to the floor surface of a building to which the construction structure is applied, for example, a direction from the floor to the ceiling, is referred to as a height direction.

In one embodiment, the anti-vibration pad (110) may be placed on the floor of a building, for example, the upper surface of a slab (S). The anti-vibration pad (110) may be formed in a rectangular plate shape when viewed from above. The anti-vibration pad (110) may include a flexible material, for example, at least one of silicone or foamed urethane. The anti-vibration pad (110) is placed between the panel support (123) (120) described below and the upper surface of the slab (S), and may perform a function of buffering an impact applied from the panel support (123) (120) to the slab (S). In one embodiment, a protrusion structure having a recess formed therein may be formed on the surface of the anti-vibration pad (110). When a load is applied to the anti-vibration pad (110), the shape of the surface of the anti-vibration pad (110) is deformed according to compression, and the impact applied in the height direction may be absorbed. In one embodiment, the anti-vibration pads (110) may be arranged at regular intervals on the slab (S). For example, the anti-vibration pads (110) may be arranged in a grid shape on the floor surface of the building. A panel support (123) (120) described below may be arranged on the upper portion of each anti-vibration pad (110).

In one embodiment, the panel supports (123)(120) are respectively arranged on the upper surface of the anti-vibration pad (110) and can support the floor panel (140) so that the floor panel (140) described below is installed at a position spaced from the floor surface. In one embodiment, the panel supports (123)(120) can include a base arranged on the upper surface of the anti-vibration pad (110), a panel support portion spaced from the base and supporting the floor panel (140), a spring member (122) connecting the base and the panel support portion in the height direction, and a connecting member positioned between the base and the panel support portion.

In one embodiment, the base may include a base plate (121) arranged to be in contact with an upper surface of the anti-vibration pad (110), and a first connecting portion protruding in the height direction from the base plate (121). In one embodiment, the base plate (121) is formed in a plate shape and may be fixed to a position set on a floor surface. For example, the base plate (121) may include a fixing groove that penetrates in the height direction and into which a fixing member, such as a piece, may be inserted and fixed. In one embodiment, the base plate (121) may be formed of a material having sufficient rigidity to support the self-weight of the floor panel (140) described below and a load applied from above, for example, a durable material such as steel. Meanwhile, in the drawing, the base plate (121) is illustrated as having a rectangular shape, but the shape of the base plate (121) is not limited thereto. In one embodiment, the base plate (121) may have substantially the same shape as the anti-vibration pad (110) when viewed from above. In one embodiment, the first connecting portion is formed in a pillar shape and at least a portion thereof can be inserted and fixed into the interior of a spring member (122) described later. Although not shown in the drawing, the first connecting portion can be detachably connected to the spring member (122) in a screw-joint manner.

In one embodiment, the panel support may be positioned at the top of the base along the height direction. The panel support may be connected to the base in a non-contacting state via a spring member (122). The panel support may support the lower side of the floor panel (140) via the upper surface. The structure of the panel support will be described later.

In one embodiment, the panel support may be connected to the base via a spring member (122). For example, a connecting post extending in the height direction may be connected to the lower side of the panel support, and the connecting post may be connected in such a way that at least a portion of the connecting post is inserted into the spring member (122). In one embodiment, the connecting post may be detachably connected to the spring member (122) via a screw connection.

In one embodiment, the spring member (122) can connect the base and the panel support in the height direction. The spring member (122) can compress according to the load applied to the panel support. According to the compression of the spring member (122), the load applied from the panel support to the base can be reduced.

In one embodiment, the connecting member may be connected between the panel base and the panel support. For example, the connecting member may be connected to a connecting column connected to the lower side of the panel support. In one embodiment, one panel support (123)(120) may be provided with a pair of connecting members spaced apart along the height direction. In one embodiment, the connecting member has a length direction perpendicular to the height direction and may be fixed to an insulating panel (130) described below.

In one embodiment, the insulation panel (130) is placed on the slab (S) and can perform an insulation function for the floor of the building. In one embodiment, the insulation panel (130) can be formed of a material having high insulation properties, for example, glasswool. The insulation panel (130) can be formed in a rectangular panel shape. In one embodiment, the insulation panel (130) can be connected to the panel support (123) (120) so as to be spaced apart from the upper surface of the slab (S) by a predetermined distance.

In one embodiment, the insulation panel (130) may be connected to the panel support (123) (120) such that the edge is positioned between the base of the panel support (123) (120) and the panel support. For example, the lower surface of the insulation panel (130) may be secured to the upper surface of the base plate (121). In this case, the insulation panel (130) may be fixed in position relative to the panel support (123) (120) by being fixed to the connecting member through a member such as a fastener. With this structure, since the insulation panel (130) is spaced from the bottom surface of the building, for example, the upper surface of the slab (S), an air layer is formed between the insulation panel (130) and the slab (S), so that more effective insulation performance can be secured.

In one embodiment, the floor panel (140) may form an interior floor of a building. The floor panel (140) may be formed in the form of a double floor plate, such as an access floor, a double floor plate, or a double floor, for example. In one embodiment, the floor panel (140) may be installed on the panel support (123) (120) so as to be spaced apart from the upper surface of the slab (S). The floor panel (140) may form a space between the slab (S) and the floor panel, in which wires, etc. may be arranged. In one embodiment, the floor panel (140) may be installed in a form in which the corners are supported by the panel support (123) (120) based on a state viewed from above. For example, the corners of four floor panels (140) may be supported by one panel support (123) (120). In one embodiment, the floor panel (140) may be formed in a square shape when viewed from above. The floor panel (140) may include an upper plate and a lower plate connected to the lower side of the upper plate.

In one embodiment, the top plate may be formed to have a larger area than the bottom plate. For example, the top plate may be formed to cover the entire upper surface of the bottom plate. In this case, the edge of the top plate of the floor panel (140) may protrude outwardly from the bottom plate. In one embodiment, a step portion may be formed at each corner of the top plate to be positioned downwardly to be secured to the support pillar (125) of the panel support member.

In one embodiment, the lower plate may be formed with a structure capable of absorbing or dispersing a shock applied to the upper plate. A panel space may be formed inside the lower plate. The panel space may be formed integrally inside the lower plate, or may be formed as a plurality of spaces separated from each other. In one embodiment, for example, a filler may be filled inside the panel space.

In one embodiment, the floor panel (140) may be supported at the lower side by a panel support member. Referring to FIGS. 4A and 4B, the panel support member may include a support plate, a support pillar (125) extending upwardly in the height direction from the support plate, and a plurality of support members (124) protrudingly formed on the upper portion of the support plate.

In one embodiment, the support plate may be formed in a rectangular shape when viewed from above. At least one lower edge of a floor panel (140) may be secured to an upper surface of the support plate. In one embodiment, the lower edges of up to four floor panels (140) may be secured to one support plate. In this case, the four floor panels (140) may be arranged such that their respective edges come together with respect to the center of the support plate, for example, the support pillar (125).

In one embodiment, a plurality of support members (124) can guide the seating position of the floor panel (140) with respect to the support plate. The plurality of support members (124) can be positioned between adjacent floor panels (140) when the support plate is viewed from above. For example, four support members (124) can be formed on the upper portion of the support plate so as to be positioned between each corner of the support plate. When the four floor panels (140) are seated on the support plate, each of the support members (124) can support the lower side of the upper plate of the adjacent floor panel (140).

In one embodiment, the support pillar (125) may be formed to protrude in the height direction from the center of the support plate. The support pillar (125) may be formed in a cylindrical shape, and the upper surface may be formed to be stepped inward. In one embodiment, when the floor panel (140) is secured to the panel support portion, for example, when the lower edge of the floor panel (140) is secured to the support plate, the upper edge of the floor panel (140) may be secured to the upper surface of the support pillar (125). For example, the upper surface of the support pillar (125) may be formed to be stepped inward, and the stepped portion formed at the upper edge of the floor panel (140) may be secured to the upper surface of the support pillar (125). In one embodiment, when four floor panels (140) are connected to the panel support, the upper edges of the four floor panels (140) secured to the panel support may be arranged in a manner such that they come together on the upper surface of the support pillar (125). In this case, a fixing screw that is screwed upward may be connected to the upper end of the support pillar (125). The fixing screw may cover and support the upper surface of the upper edge of the floor panel (140) while the upper edge of the floor panel (140) is secured to the upper surface of the support pillar (125).

In one embodiment, a buffer pad may be arranged on the upper surface of the panel support. The buffer pad may be arranged between the panel support and the floor panel (140) when the floor panel (140) is secured to the panel support. The buffer pad may buffer a force acting between the floor panel (140) and the panel support. The buffer pad may be formed of a flexible material, for example, a material such as urethane or silicone.

In one embodiment, the pipe support panel (160) may be arranged on the upper part of the floor panel (140), for example, on the upper plate of the floor panel (140). The pipe support panel (160) may be formed in a plate shape, and may have a pipe mounting groove (161) formed on the upper surface for mounting the pipe. In one embodiment, as shown in FIG. 6, the pipe mounting groove (161) formed on the pipe support panel (160) may be formed in a shape in which various shapes of pipes may be mounted, regardless of the design shape of the pipe. For example, the pipe mounting groove (161) may include a straight shape and a curved shape. In one embodiment, the pipe support panel (160) may support at least a portion of the pipes arranged on the floor of the building, as shown in FIG. 5. In one embodiment, a heating function may be performed by moving a fluid for heating inside the pipes arranged on the pipe support panel (160). In one embodiment, when the pipe is secured in the pipe securing groove (161) of the pipe support panel (160), the pipe may not protrude from the upper surface of the pipe support panel (160).

In one embodiment, a steel plate panel (170) may be placed on top of a pipe support panel (160). The steel plate panel (170) may be formed of a highly rigid material, for example, a metal material such as steel or aluminum.

In one embodiment, the lower buffer plate (151) may be disposed between the floor panel (140) and the support panel, and the upper buffer plate (152) may be disposed between the pipe support panel (160) and the steel plate panel (170). The lower buffer plate (151) and the upper buffer plate (152) may be formed of, for example, polyethylene (PE) or polyethylene terephthalate (PET) material. The lower buffer plate (151) and the upper buffer plate (152) may perform the function of absorbing impact acting between the floor panel (140), the support panel, and the steel plate panel (170).

The finishing panel (180) is arranged on the upper surface of the steel plate panel (170) and can form the appearance of the bottom surface of the building. In other words, the finishing panel (180) can be seen by the user's eyes. In one embodiment, the finishing panel (180) can cover the steel plate panel (170) so that the steel plate panel (170) is not exposed to the outside, while at the same time securing the aesthetic appeal of the construction structure.

With this structure, the dry floor construction structure according to one embodiment can secure a high degree of freedom in construction in response to the design conditions of the interior of the building by constructing the interior floor of the building through a dry construction method. In one embodiment, the dry floor construction structure can reduce noise occurring between each floor of the building by reducing impact applied from the upper part of the floor, for example, impact applied by a user or impact due to the load of a heavy object, to the slab (S).

Below, the construction steps of the dry floor construction structure will be described.

First, referring to FIG. 2, in the initial stage of the dry floor construction structure, a plurality of panel supports (123)(120) may be arranged at regular intervals on a building floor surface, for example, a slab (S). The arrangement interval of the panel supports (123)(120) may be determined according to the size of the floor panel (140). Since each panel support (123)(120) supports each corner of four floor panels (140), the panel supports (123)(120) may be arranged at each position corresponding to the corner of the floor panel (140). In one embodiment, a vibration-proof pad (110) may be arranged below the panel support (123)(120) to alleviate the impact between the slab (S) and the panel support (123)(120).

Referring to FIG. 3, an insulating panel (130) for insulation may be placed between a plurality of panel supports (123)(120). The insulating panel (130) may be positioned between the base of the panel support (123)(120) and the panel support. In this case, since the insulating panel (130) is placed at a position spaced apart from the slab (S) by a predetermined distance, direct heat transfer from the insulating panel (130) to the slab (S) may be prevented.

Referring to FIG. 4, a floor panel (140) may be placed on the panel support portion of the panel support member (123)(120). Each corner of one floor panel (140) may be supported by four panel supports. With the floor panel (140) secured to the panel support portion, the position of the floor panel (140) relative to the panel support portion may be fixed through a fixing screw inserted into the support pillar (125).

Referring to FIG. 5, a pipe support panel (160) may be placed on the upper portion of the floor panel (140). In this case, a lower buffer plate (151) may be placed between the floor panel (140) and the pipe support panel (160). Pipes for heating may be placed in the pipe fixing grooves (161) of the plurality of pipe support panels (160).

Referring to FIG. 1, after the pipe is installed on the pipe support panel (160), a steel plate panel (170) may be placed on the upper part of the pipe support panel (160). In this case, an upper buffer plate (152) may be placed between the steel plate panel (170) and the pipe support panel (160). A finishing panel (180) may be placed on the upper part of the steel plate panel (170).

Although the embodiments have been described with limited drawings as described above, those skilled in the art can apply various technical modifications and variations based on the above. For example, even if the described techniques are performed in a different order than the described method, and/or the components of the described system, structure, device, circuit, etc. are combined or combined in a different form than the described method, or are replaced or substituted by other components or equivalents, appropriate results can be achieved.

Therefore, other implementations, other embodiments, and equivalents to the claims are also included within the scope of the claims.
