Description

Construction method of gym floorboard support structure and its floorboard support structure {THE METHOD OF CARRING OUT CONSTRUCTION OF SUPPORTING FLOORING FOR A DRILL HALL AND IT'S CONSTRUCTION}

The flooring of the indoor gym is composed of elastic flooring by flooring material, floorboard flooring, eclectic type between floorboard and flooring material, and a space layer is formed between flooring materials. There are various configurations formed of laminated layers that are in contact.

As a specific example of the prior art, a domestic registered patent publication (Registration No. 10-0648527) introduces a method of constructing a wooden floor for shock mitigation and its wooden floor. Looking at the technical configuration of the anchor of the steel frame 20 having a rectangular metal material in the upper portion in the upper portion and the anchor 21 is formed by extending in the lower vertical direction in the center of the bottom of the housing portion 22 Step 21 is put out to maintain a constant interval in the horizontal, vertical direction on the concrete floor and the dust-proof rubber 30 is in close contact with the lower portion of the receiving portion 22 and then fixed at the intersection of the horizontal, vertical frame is lower Step of fitting the wooden column 40 of the grid-like wooden frame 50 consisting of the wooden column 40 extended to match the accommodating part 22 of each steel frame 20 and the wooden frame 50 The construction method and the structure of the wood floor to be constructed by the step of placing the plywood 60 in close contact with the side and forming the enamel 70 layer on the plywood 60 layer and assembling the wood floor thereon But you may encounter the following problems: There.

Such a configuration must first be embedded in the concrete floor surface of the numerous anchors 21 of the steel frame 20, the concrete floor layer may be vulnerable and may cause cracks if the floor is a wooden pillar (vibration) 40) can be mitigated to some extent by the anti-vibration rubber 30, but because the side of the wooden pillar 40 and the receiving portion 22 of the metal material is in contact with the side to prevent the vibration transmitted therefrom Can not. In addition, when the concrete floor is in contact with the ground, the moisture penetrating from the ground is penetrated through the concrete layer by capillary action, so that it can easily corrode the steel frame 20 including the metal anchors 21 and made of wood. Plywood or hardwood floors also do not last long.

As another conventional technology, the technical contents of the "soundproof and dustproof joist system and floor structure using the same" are introduced in Korean registered patent publication (Registration No. 10-0648453). It is formed on both sides of the processing plywood 12 in the "c" shaped insertion hole (13a, 13b) formed in the upper side of the dust-proof pad 12, as shown in Figure 3 on the concrete floor to lay a moisture-proof film (11) The protrusions 12a and 12b are inserted and joined so that the assembly is arranged in a row in the longitudinal direction on the film bottom surface, and then the plywood 14 is adhered to the front surface thereof, and then the frying ring 15 is placed thereon. As the floor structure assembled in the direction orthogonal to this), such a floor structure can be said to have excellent dust resistance, but since the processed plywood 12 of the joist system 30 becomes a joist, the processed plywood 12 is thinly and partially disposed. Due to its structure, impact resistance and pressure resistance are insufficient, so it is impossible to perform the joist function, and it is possible to damage or puncture holes during flooring work just by putting a thin film on the surface that is waterproofed. It is difficult to expect to be.

Another conventional technology, Korean Patent Registration No. 26580 describes the floor structure installed in the gymnasium, but it uses a special type of anti-vibration rubber, but not only the impact effect is low, but also the construction method is difficult, economical and the construction period is long. There is a problem losing.

In addition, the Patent Publication (Registration No. 476701) is an assembly formed so that the fitting groove of the floor plate can be coupled to the fitting groove formed on the upper side of the connector to the sliding coupling to the guide groove of the rubber frame fixed to the floor as a floor plate assembly The domestic registered utility model publication (Registration No. 287092) has a coupling groove 22 having a predetermined depth on each side in the longitudinal direction, respectively, and a coupling protrusion 24 having a predetermined size and height on one side in the width direction. ) Is formed on the other side of the floorboard material 20 and the bottom surface of the floorboard material 20 provided with coupling grooves 22 to which the engaging projections of the other members are fitted on the other side. A locking jaw 31 having a “T” shape is formed at one end of the upper surface so as to be simultaneously inserted into and fixed to the coupling grooves 22 of the floorboards of the rear row, and the fitting groove 34 having a predetermined depth on the bottom of the locking jaw 31. It is formed, and the The fixing plate 30 of the plastic material and the different fixing plate 30 are fitted with the fitting jaw 32 which is coupled to the fitting groove of the other member on the other end formed with the groove groove 34 is detachably continuous And a plurality of fixing clips 50 which are elastically coupled to both ends of the fitting groove 34 and the fitting jaw 32 which are mutually coupled so as to prevent their separation after being coupled by the fitting member 34 and the fitting jaw 32. Consists of a fixed thickness elastic pad 60 is installed on the bottom surface of the fixed plate 30 and the upper surface of the concrete floor, the floor plate material of the front and rear rows are fixed at the same time by the fixing plate 30 provided on the bottom surface It relates to a floor assembly made.

Both of the above descriptions relate to floorboard assemblies, which can be easily assembled, but are not suitable for floorboards that require strong impact or large pressure resistance, such as a gym.

The present invention provides a construction method of the gym floorboard support structure and accordingly the gym floorboard support structure, and by using a double joist vertically can withstand the strong pressure resistance, impact resistance and shock-absorbing by laminating dustproof rubber, glass wool and asphalt layers It is excellent in dustproofness, soundproofing, and heat insulation, and it has excellent waterproofing property by laminating synthetic resin film and asphalt layer on the floor layer, and it is possible to prevent corrosion of the structure by moisture by securing sufficient drying space between the floor layer and the laminated floor layer. To provide a construction method of the gym floorboard support structure and accordingly provide a gym floorboard support structure.

The surface is smoothly treated with a waterproof plastering layer on the concrete floor surface, and the PE film is bonded on the treated surface to be covered, and the asphalt sheet is adhered on the film to form an asphalt layer.

A red cedar colony line (angular neck) is placed on a line of anti-vibration rubber plates arranged in a row with a pair of wedge supports grounded diagonally in a shape so as to maintain a constant interval in the horizontal and vertical directions, and the anti-vibration rubber plates bonded to each of the enclosed wedge supports. The fixed plywood, which cross-links each colony line and the colony line arranged in parallel, is covered, and the small intestine is fixed on the retreaded waterproof plywood, while the small plywood is fixed directly in the arrangement position of the lower colony. And filling the glass wool press-molded in the space formed by the waterproof plywood and fixed cover with water-resistant plywood on it, so that the conventional maple leaf can be installed on the plywood in the direction orthogonal to the joist can achieve the object of the present invention Construction method of gym floorboard support structure and its floorboard support It could provide the water.

The construction method of the gym floorboard support structure of the present invention and the floorboard support structure according to the method are excellent in strength and waterproof function of the plastering layer, which is the foundation layer, and laminated in three layers of glass wool mat, dustproof rubber plate and rubberized asphalt sheet. It can be almost perfect for dust and noise absorption, and also has excellent shock absorption, which can buffer shocks transmitted to players, and ensures sufficient space between floor and floor laminates with excellent waterproofness of the floor. Oxidation corrosion due to moisture of the structure can be prevented to improve the durability of the floorboard support structure.

In order to achieve the above-described object of the present invention, the construction method of the gymnasium floorboard support structure and the support structure other than the construction method thereof can be clearly understood by first explaining the construction method. Accordingly, first, the construction method of the gym floor support structure according to the construction order,

It relates to a construction method of the gymnastics floorboard support structure comprising the step of inserting and fixing the dustproof urchin member 19 in the space formed between the side wall (16) surface and the floor horizontal laminated structure 20.

Cement mortar used in the construction method,

1 ~ 2.5wt% of synthetic resin emulsion and 0.5 ~ 1wt% of silane capping agent have excellent waterproofing effect as cement mortar composed of conventional cement mortar composition. Synthetic resin (acrylic resin) emulsion system has significantly improved resistance to water absorption of mortar concrete because voids of cement hydrate and aggregate (sand) form a structure of polymer or continuous polymer film. As a silane having a double bond functional group, it combines organic materials such as synthetic resins and inorganic materials such as sand, glass, and metal to increase the strength of the plaster mortars significantly and makes the tissues dense. Can be improved.

In addition, the PE film that is adhesively coated on it may use a thickness in the range of 0.08 ~ 0.5mm, and the acrylic film is coated on the front surface by coating an acrylic adhesive with a thin film on the plastering layer.

In addition, the asphalt sheet is rubberized asphalt, which has greater ductility than general asphalt, and has a high resistance to cracking and has a fatigue life of at least three times under a wide range of loads. Use a 3mm range.

In addition, the asphalt is wound in a roll shape, and the release PE film is bonded to one side, and the asphalt film is bonded to the PE film surface covered on the inner layer, and the edge surface is thermally bonded, and the release film adhered to the asphalt layer is bonded. Leave it as it is.

Originally, asphalt durability depends on how long fluidity, viscosity, and adhesion are maintained and exerted. Exposing the surface of asphalt layer will lead to aging due to oxidation and hardening due to volatilization of asphalt. Therefore, if the film is bonded as described above, durability can be extended.

In addition, the wedge has an unevenness 11a formed on the upper and lower wedge contact surfaces as shown in FIG. 4, or the tip portion of the wedge is formed as a thick portion as shown in FIG. 5, and the slope is smooth and the ground plane is formed with a wave shape 11b. As shown in Fig. 6, a plurality of holes 11d are formed in the lower wedge contact surface 11c to pin 11e.

Such a structure is adapted to adjust the height as the wedge to form the floorboard in a horizontal plane.

The anti-vibration rubbers located on the wedges are NR and BR, which withstand loads, have less deformation and less creep.

The colony line below the waterproof plywood and the small intestine just above the abdomen use solid cedar with high texture and high pressure resistance. In addition, the glass wool mat filled in the space formed by the waterproof plywood and the small intestine on both sides is a tightly pressed glass wool sheet, which is filled in the space using a sheet slightly thicker than the thickness of the small intestine, and To match the height of the small intestine.

In addition, the conventional ply ring of various types are installed on the waterproof plywood, and the waterproof plywood and the waterproof plywood have a waterproof coating layer formed on the surface to have a waterproofing and waterproofing function, and the base member 19 is an anti-rubber base member as shown in FIG. The dustproof rubber skirting member is inserted and bonded between the gap formed by the furnace wall and the side of the floor laminate 20 to finish the construction of the floorboard support structure.

Here, the small intestine, the large intestine, the anti-rubber plate and the wedge support and the laminated structure are stacked in a pyramid shape, and each cross-section center is placed on one vertical line.

The function and effect of the gym floorboard support structure by the above construction method are as follows. First, the plaster layer on the concrete floor surface is strongly bonded and bonded with the concrete floor surface by the addition of silane capping agent, and the structure of the plaster layer is dense. The addition of synthetic resin emulsion provides excellent water resistance and strengthens the strength of the plaster layer.

Moreover, the PE film bonded on the inner layer, the rubberized asphalt layer and the laminated layer of PE film adhered on it, can be excellent in waterproofing function. The dustproof function and the noise function are caused by the vibration and noise caused by the strong impact generated in the free ring. Is absorbed by the first glass wool sheet, secondly by the anti-vibration rubber plate, and thirdly by the asphalt layer, so the vibration and noise functions are almost perfect, and the horizontal floor laminate is 2mm thick ring, 12mm water resistant. Plywood, 25mm glass wool mat, 12mm waterproof plywood, small space between small and small ships, 35cm, structured like a leaf spring of automobile, absorbing strong impact resistance and pressure resistance and cushioning It can alleviate the impact on the waist and knee joints of players).

In addition, it is possible to prevent the oxidation corrosion caused by the moisture of the structure by ensuring the excellent waterproofness of the floor and sufficient drying space between the floor and the floor laminate to ensure the durability of the entire structure.
