Description

Floor system by low-floor AL joist structure and low-floor AL joist structure {Structure of low deck batten and system constructing the floor by structure of low deck batten and method constructing the floor by structure of low deck batten}

The present invention relates to a floor system using a low-floor AL joist structure and a low-floor AL joist structure, and a floor installation method using a low-floor AL joist structure. By assembling and inserting the distance standard chuck and reinforcing support 300, the sports vertical load reinforcing support plate 200, and the hexahedral post 400 of the suspension stacking method, not only is it easy to form one unit, but also the height is increased by installing the units consecutively. While it is easy to construct a low-floor floor system of 70 to 80 mm or less, the width direction gap between the low-floor AL joists 100 becomes the design gap by inserting the chuck and reinforcing support 300 based on the precision joist spacing. Not only is the ball anti-elastic performance uniformly maintained over the entire floor, but it is easy to adjust the reinforcement corresponding to the maximum intensive exercise load, and the exercise noise is minimized by the minimized resonance space, and at the same time, they are one It is a useful invention integrated into a low-floor floor system.

In general, the floor structure is a single-joist floor structure in which wooden deck → hardwood floor panels are sequentially installed on the joists, as shown in FIG. 1A.

1A is disclosed in Patent No. 10-1459559 (system floor installed in gymnasiums, auditoriums, etc.). This will be referred to as "prior art" hereinafter.

Since the present invention is a single-lane joist, the problems with the single-lane joist will be examined based on the prior art.

1) Prior art floor structure

A) According to FIG. 1A, the composite joists 10 are supported by the support bolts 40 of the pedestal 50, and the wooden deck 5 (eg, plywood) and the wooden floor panel 1 are sequentially placed thereon It is a layered structure with The composite joist 10 is composed of an upper wooden joist 13 and a lower metal joist 11. The wooden deck 5 and the wooden floor panel 1 are fixed to the upper wooden joists 13. The reason why the wooden joist 13 is located above the metal joist 11 is to facilitate the fixing of the wooden deck 5 and the wooden floor panel 1.

B) The floor structure of FIG. 1a is a single-joist structure. Four joists A, B, C, and D are single joists in FIG. 1A. Usually four (A, B, C, D) single joists are placed first. In this state, the wooden deck 5 → the wooden floor panel 1 is sequentially installed thereon. However, the state in which only four (A, B, C, D) single-joist lines are arranged is an unstable structure for the left and right. If there is no left and right support structure, it is because it easily falls to the left and right. The joist spacing maintaining bar 70 of FIG. 1A is a structure for left and right support.

C) The floor system of FIG. 1a is classified as a solid joist system with respect to a low floor joist system.

In general, a low-floor joist system is classified as a height corresponding to a height of 70 mm to 80 mm from the floor concrete to the top wooden floor panel finish line through the post (P; 20). The low-floor joist system has the advantage of minimizing noise amplification by minimizing the resonance space of gymnasium exercise noise as the space height from the floor concrete to the support (P; 20) is 20 mm or less.

In contrast, as shown in FIG. 1B, the height of the post (P; 20) of the composite joist (10) is the height of the height of the metal support (50) and the height of the rotary height-adjusting metal post bolt (40). As a rotational height-adjustable metal post bolt structure, the height of the post (P; 20) cannot be lowered to 100 mm or less due to its structure. This will be referred to as a solid joist system hereinafter.

The structure of the rotating height-adjustable metal post bolt (40) is the limit of the solid type joist system that cannot lower the height of the post (P). When the height of the post (P; 20) of this solid type joist system is added to the height of the composite joist (10) above it, the height of the entire floor system in FIG. 1a is inevitably at least 150 mm to 200 mm. The maximum height of the post (P; 20) of the solid joist system becomes a resonance space that is maximized, so there is an unavoidable problem of maximum noise amplification for gymnasium exercise noise.

D) The structure of the relationship between the composite girth (10) and the post (P; 20) will be described.

A post (P) 20 is assembled and fixed to a rectangular cutout 12 formed in the metal rigging line portion 11 of the composite girder 10. In other words, the post (P; 20) is located only where the rectangular cutout (12) is. The position of the post (P; 20) is an invariable fixed point. The rectangular cutout 12 is formed only in the front and rear of the metal loading line 11 in the longitudinal direction. As long as the rectangular cutout 12 is not formed in the metal loading line portion 11, the assembly of the post (P) 20 is impossible.

E) After the supports (P; 20) at regular intervals are installed on the concrete floor surface of FIG. 1a, the single-row joists (A, B, C, D) are assembled thereon.

Even if the single joist is connected by the joist spacing maintenance bar 70, if the condition of the concrete floor is sloped or uneven, the single joist (A, B, C , D) is installed at an inclined angle, which not only entails the risk of workers for installing the wooden deck 5 thereon, but also has a problem in that the installed floor structure itself is unstable.

F) Looking at the regular pattern method by the four (A, B, C, D) single joists of FIG. 1a, the supports (P; 20), and the joist spacing maintaining bar 70 are as follows.

The pattern method is a pattern at regular intervals formed by the four single joists (A, B, C, D) of FIG. say that

Although the pattern method is easy and convenient to install the gym floor, it is a structure in which the position of the post (P; 20) cannot be varied with respect to the place where the exercise load is concentrated (eg, the bottom floor of the basketball court), so the floor of FIG. 1A As the structure is an unchanging support (P; 20), there is a problem in that it cannot cope with the intensive exercise load.

For example, since an athletic game on a basketball court is a game in which airborne players repeatedly move quickly toward both goalposts, the area where the maximum intensive exercise load is applied is the crest of the goal. During the game, the bottom of the goal is momentarily greater than the original design strength, but it is repeatedly caught. As a result, it gradually sinks down from the bottom of the bone, resulting in the loss of function as a gym as the ball anti-elastic performance gradually deteriorates. Arrangement” structure, so it is much more difficult to repair than the “sequential fixing method”, and there are inefficient and uneconomical problems.

On the other hand, looking at the installation of the regular pattern method by the four single joists (A, B, C, D), the support (P; 20) and the joist spacing maintaining bar (70) of FIG. 1A are as follows.

In Figure 1a, the front row B and D of the single row joist, and the back row A and C of the single row joist form a pair, respectively. The joist spacing maintaining bars 70 are connected and fixed between the supports P of each pair of single joists. In other words, a joist spacing maintenance bar (70-①) is installed on the support (P-①) of a pair of single joists B↔D, and a joist spacing maintenance bar (P-②) on the support (P-②) of a pair of single joists A↔C. (70-②) is connected and fixed. In this way, the connection fixing method of the pair of single joists and the joist spacing maintaining bar 70 fixed to the post P is referred to as a "pair of connection fixing method".

The relationship between the "connection fixing method of a pair (A↔C)" and the "connection fixation method of a pair (B↔D)" is a "staggered arrangement relationship" with respect to the joist spacing maintenance bar 70.

「Staggered arrangement relationship」 of 「A pair of connection fixing method」 is, first, each pair A↔C and B↔D is an independent relationship with respect to the joist spacing maintenance bar 70, and second, the B of B↔D passes between the intervals of A↔C, but is not fixed anywhere in A↔C, so independent A↔C or independent B↔D are free to move in the width direction, respectively. Third, independent A↔C and independent B It is a relationship in which ↔D forms a “staggered arrangement relationship” with each other.

Summarizing this, in the prior art, unlike the "sequential fixing method" in which the joist spacing maintenance bars are sequentially installed one by one for one single joist, the "staggered arrangement relationship" by the "pair connection fixing method" It is a method that is installed while achieving. At this time, the "staggered arrangement relationship" is characterized by the fact that independent A↔C or independent B↔D can move freely in the width direction.

Looking at the problems of the prior art from this point of view are as follows.

As described above, as far as the prior art achieves a "staggered arrangement relationship" by a "pair of connection fixing method" for A↔C or B↔D, the joist spacing maintenance bar 70-① and the joist spacing maintenance Even if the spacing in the width direction between A↔C and B↔D is exactly the design interval by bar (70-②), the B of B↔D is between A↔C and the B of A↔C is between B↔D. As C is arranged alternately, a joist arrangement structure of A↔B↔C↔D with three widthwise joist lines is formed, but A↔C or B↔D among the elements of the arrangement structure moves independently and freely in the width direction Therefore, there is a problem in that it is virtually impossible to install all three widthwise joist spacings to exactly match the design spacing without errors.

In addition, as described above, after the joist arrangement structure of A↔B↔C↔D is installed by 「a pair of connection fixing method」 and 「staggered arrangement relationship」, as its installation continues to expand toward the entire gym floor, A↔ There is a problem in that the ball resilience performance of the entire floor is significantly deteriorated as the error generated in B↔C↔D is serially diffused and amplified to the entire gym floor.

All three widthwise joist spacings are very sensitive to the performance response of the ball rebound even if the error size from the design spacing is only 1 to 3 mm. This is a common fact in the specialized field of international sports. It is for this reason that the international level of gymnasiums is defined by ball rebound performance. The core technology in the gym floor field is to minimize the error.

On the other hand, the wooden deck 5 → the wooden floor panel 1 is fixed to the wooden joist part 13 of the composite joist 10 by a tacker pin. However, since there is a problem in that it is difficult to fix the tacker pin with the metal material joist part 11, fixing the tacker is facilitated by assembling the upper wood joist part 13 to the lower metal material joist part 11.

(a) The present invention is a low-profile AL joist 100 structure with a rectangular cross-section with a minimized height, and L-shaped protrusions 150 and wedge protrusions 160 are provided on the upper and lower portions of both side portions 130, and the bottom portion 120 In ), the departure prevention guider 170 protruding from both side portions 130 is integrally formed in the longitudinal direction of the AL joist 100, while the wedge protrusion 160 and the L-shaped protrusion 150 and the departure prevention guider ( 170) in connection and assembly of related members, first, by closely inserting and assembling the chuck and reinforcing support 300 based on the precise distance of the joist into the wedge protrusion 160 of the sequentially installed and opposed two-low-floor AL joists, successively low-floor AL All widthwise spacings facing each other between the joists 100 are converted into design intervals by the joist precision spacing standard chuck and reinforcing support 300, and at the same time, the precision of the design interval is easily secured, and secondly, in the case of a basketball court, under the rim By assembling the sports vertical load reinforcing support plate 200 at the position of the L-shaped protrusion 150 corresponding to the maximum intensive exercise load, not only the position variable reinforcement for the maximum exercise load is easy, but also the maximum exercise by the reinforcement The sagging of the wooden deck (D) and the wooden floor panel (F) under the frame due to the load is prevented, and thirdly, the suspension laminated type 6 The face support 400 is inserted, but the position of the support 400 is variable along the longitudinal direction, so that the support response of the support 400 to the size of the intensive exercise load is efficient, so that the position setting is variable and the function is different. By assembling the three members as one unit in the low-floor AL joist 100 structure, all widthwise intervals between the sequential low-floor AL joists 100 are installed at exactly the design intervals, and the reinforcement corresponding to the maximum intensive exercise load is increased. The purpose is to build a low-floor floor system (height 70 to 80 mm or less), which is possible and at the same time, considering that the movement noise is minimized by the minimized resonance space,

(b) In addition, as all widthwise intervals of the sequential low-floor AL joists 100 are converted to design intervals, it is possible to adjust the reinforcement in response to the maximum intensive exercise load, and at the same time, the state in which the low-floor floor system with minimized exercise noise is built Since all width directions between the low-floor AL joists 100 are converted to design intervals, there is no error between width direction intervals, so that the ball anti-elasticity performance is uniformly exhibited throughout the gymnasium floor. Another purpose is,

⒞ In addition, in the case of a basketball court, even if the maximum intensive exercise load is directly applied to the bottom area, the size is not the same throughout the bottom area, and there is a difference in size, so the variable position adjustment structure [ie sports vertical load Adjusting the position of the variable positioning structure is easy by adjusting the position of the reinforcing support plate 200, the chuck-cum-reinforcing support 300 and the hexahedral pillar 400] to correspond to their large and small sizes, Another purpose is to efficiently and double the durability of the floor in the area under the bone,

⒟ In addition, by making the suspended hexahedral pillar 400 stacked in the order of "choice 410 → leveling kit 420 → anti-rubber 430", vertical and horizontal vibrations are prevented due to the separation between the lamination and the lamination. Another object is to minimize the height of the pillar 400 (eg, 20 mm or less in height), as well as to exhibit a high degree of earthquake resistance for the.

The configuration of the low-rise AL joist structure of the present invention is described as follows.

In a floor joist structure in which a wooden deck (W) → a wooden floor panel (F) is supported by a post

The low-floor AL joist 100 has a height consisting of a wooden deck (W) → a plane portion 110 where a wooden floor panel (F) is installed, a bottom portion 120, and both side portions 130 and 130. The upper L-shaped protrusion 150, which has a minimized rectangular parallelepiped shape and has a hollow part S inside, and inserts and assembles the insertion groove 225 of the sports vertical load reinforcement support plate 200 into both side parts 130 and 130. ), and the heel wedge protrusion 160 into which the wedge insertion groove 310 of the chuck and reinforcing support 300 based on the joist precision interval is inserted and assembled along the longitudinal direction of the AL joist 100. On the other hand, In the bottom portion 120, the anti-separation guider 170 into which the hexahedral post 400 of the suspended stacking method is inserted is integrally formed along the longitudinal direction of the AL joist 100. am.

here,

2 Support of the joist joint member 500 in the hollow part (S) of the low-profile AL joist 100 on both sides of the longitudinal connection in connecting the low-level AL joist 100 in the longitudinal direction by the joist joint member 500 The reinforcing insert 510 is inserted and assembled, but the central protruding level portion 520 of the joist joint member 500 is at the same plane level as the plane portion 110 of the AL joists 100 on both sides. It is an AL long line structure.

Not only that,

Reinforcing protrusions 140 are formed in the upper and lower parts of the hollow part S of the low-profile AL joist 100, and a protrusion insertion groove 512 is formed in the joist joint member 500 to be inserted corresponding thereto. It is an AL long line structure.

also,

The hexahedral post 400 of the suspended stacking method is formed by laminating in the order of "chopped wood 410 → leveling kit 420 → anti-rubber 430", and the post 400 is formed on the front part 442 and the rear part 444 ) and both side parts 446, and is wrapped by an AL protective cover 440, which is inserted between the departure prevention guiders 170 on both sides of the low-profile AL joist 100, but one side part 446 of both side parts 446 It is a low-profile AL joist structure characterized in that the separation prevention guider 170 corresponding thereto is fixed to the binding groove 446b of the bent binding portion 448 formed in ).

The low-profile AL joist 100 structure of the rectangular cross-section shape with minimized height of the present invention is a unit structure in which the three members with variable positioning and different functions are assembled and inserted to form one unit,

The structure of the low-profile AL joist 100 is a structure in which an L-shaped protrusion 150, a wedge protrusion 160, and a departure prevention guider 170 are integrally formed in the longitudinal direction.

The L-shaped protrusion 150 of the low-floor AL joist 100 structure has an insertion groove 225 of the sports vertical load reinforcement support plate 200, and the wedge protrusion 160 has a chuck and reinforcing support 300 based on the joist precision interval The wedge insertion groove 310 and the hexahedral pillar 400 of the suspended stacking method are assembled and inserted into both the separation prevention guides 170 to form one unit.

Looking at the unit body in which the three-member functions are integrated, first, the joist precision distance standard chuck and reinforcing support 300 is the joist precision distance standard chuck and reinforcing support at the opposed widthwise intervals between the sequential low-rise AL joists 100. By inserting 300, the spacing in the width direction accurately converts to the design spacing by the insertion, and secondly, the sports vertical load reinforcement support plate 200 reinforces the maximum exercise load, but according to the change in position Along with the efficient adaptation function, the sagging of the wooden deck (D) and the wooden floor panel (F) is prevented from sagging by its reinforcement, and thirdly, in the order of "chopped wood (410) → leveling kit (420) → anti-rubber (430)" By forming the hexahedral pillar 400 by the stacking method, the height of the pillar 400 is minimized (height 20 mm or less) by the stacking, and the separation between the stacks provides a high level of vertical and horizontal vibration. Seismic performance function is achieved.

Therefore, in the unit body, the construction of a low-floor floor system with a height of 70 to 80 mm or less is achieved by integrating the three functions of the three members assembled in the low-floor AL joist 100 structure.

In addition to this, the width direction spacing between the successive low-rise AL joists 100 is converted to the design interval without error by the joist precision spacing standard chuck and reinforcing support 300, so the ball anti-resilience performance is uniformly exhibited throughout the entire floor. there is Even if an error occurs, since the chuck and reinforcing supports 300 based on the long line precision interval are sequentially installed one by one, it exists only in one place, and unlike the prior art, there is an advantage in that no error accumulation occurs due to chain movement.

On the other hand, the connection of the two low-rise AL joists 100 in the longitudinal direction by the joist joint member 500 connects the support reinforcing insertion portion 510 of the joist joint member 500 to the hollow of the low-rise AL joist 100 on both sides. It is inserted into the part (S), but the central protruding level part 520 of the joist joint member 500 is connected so that the flat part 110 of the AL joist 100 on both sides is at the same plane level.

A unit is formed by assembling and inserting the chuck and reinforcing support (300) based on the precision interval of the joist, the sports vertical load reinforcing support plate (200), and the hexahedral post (400) of the suspension stacking method in the low-rise AL joist (100) structure, which is a unit structure. do. This unit is the basic unit of the low-floor floor system (70 to 80 mm in height) construction.

In addition, the chuck and reinforcing support 300 based on the precision joist spacing is a scale for converting the interval of the low-profile AL joist 100 into the design interval. This is said to be a member that also plays an auxiliary reinforcing role together with the sports vertical load reinforcement support plate 200.

In order for the chuck and reinforcing support 300 inserted between the opposite two low-profile AL joists 100 to be at the design interval, the wedge insertion groove 310 is completely inserted into the wedge protrusion 160, and the low-profile AL joist (100) and the chuck and reinforcing support (300) based on the precise distance must be at right angles to each other. The wedge shape of the wedge protrusion 160 and the wedge insertion groove 310 most meets these conditions.

In this way, the low-floor floor system is assembled as a unit unit in the structure of the low-floor AL joist 100 by assembling the three members with variable positioning and different functions, so that the opposing widthwise spacing between the low-floor AL joists 100 is reduced. It is a low-floor type floor system that is installed at design intervals and allows reinforcement and reinforcement adjustment corresponding to the maximum intensive exercise load and at the same time minimizes motion noise by the minimized resonance space.

In addition, the fixation of the low-floor AL joist 100 and the wooden deck (W) thereon is fixed by a tacker pin. This is because AL material, unlike steel material, is easy to fix with a toucher pin. Even in the stacking and fixing of the suspended hexahedral support 400, it is easy to fix the tacker pin, as well as the AL protective cover 440 to the hexahedron support 400.

In addition, the materials of the chuck and reinforcing support 300 based on the precise joist spacing, the sports vertical load reinforcing support plate 200, and the joist joint member 500 are preferably synthetic polymer engineering plastics with excellent durability, mechanical strength, and abrasion resistance. .

(a) The present invention is a single unit by assembling and inserting a chuck and reinforcing support (300) based on the precision spacing of the joist line, a sports vertical load reinforcing support plate (200), and a hexahedral post (400) of a suspended stacking method in a low-rise AL joist (100) structure. Not only is it easy to form, but by installing these units in succession, it is easy to construct a low-floor system with a height of 70 to 80 mm or less, and there is an efficient and economical effect,

⒝ In the low-floor floor system constructed in this way, the opposing widthwise intervals between the low-floor AL joists 100 are installed at design intervals, so that the ball anti-resilience performance is uniformly maintained throughout the floor, and maximum concentration There is an effect that it is easy to adjust the reinforcement corresponding to the exercise load, and the adjustment is possible, and there is an effect of minimizing the exercise noise by the minimized resonance space, and at the same time, these effects are integrated into one low-floor floor system It is a useful invention with the effect of
