Description

[0001] The present invention relates to a modular floor frame system for absorbing shock using a spring,

The present invention relates to a marble frame system, and more particularly, to a modular floor frame system that absorbs shocks and improves seismic performance using a spring and a rubber-made support plate.

The floors of the gymnasium, the auditorium, and the classroom are provided with flooring materials such as oak, maple, birch, and ash wood, and a shock absorber is installed at the bottom of the floor to absorb the impact.

The conventional shock absorber is provided with a shock absorbing member formed of a vibration proof rubber at the lower part of the floor so that the shock absorbing rate is low and the shock absorption rate is remarkably deteriorated due to the property that the vibration absorbing rubber becomes hard when used for a long time There was a problem.

In addition, when a floor is constructed, a plastic wedge having an inclined surface is installed on the bottom of a gym to be used for level adjustment. When a wedge is hit by a hammer, serrated protrusions are formed on the inclined surface of the plastic wedge, The height is adjusted while the protrusion is lifted and lowered, and the height adjustment is very difficult. In addition, the cushioning member and the height adjusting member were separately formed, and a lot of attaching materials were used to install the floor.

To this end, a technique has been disclosed in which a shock absorption rate is increased by using a coil spring such as Korean Patent No. 10-0789394 (Dec. 20, 2007, 'Shock Absorber for Gymnasium Floor', hereinafter referred to as 'prior art'). However, in the prior art, since the coil spring is exposed to the outside, when the coil spring is compressed and loosened, there is a possibility that the coil spring tilts to the left and right. If the spring tilts in rightward or leftward direction, the force can not be uniformly absorbed and the spring may be deformed.

Further, in the prior art, the height of the bracket is adjusted by rotating the shaft bolt fixed to the lower portion of the bracket. In other words, it is inconvenient to insert the tool under the bracket to adjust the height of the floor.

In addition, there is also a problem in that the construction is inconvenient because the support plate must be fixed to the ground by bolting in the prior art.

The present invention has been conceived to solve the problems of the conventional art as described above, and it is an object of the present invention to provide a shock absorbing device capable of absorbing impact by using a spring, The present invention provides a modular flooring system that absorbs and reduces the possibility of spring deformation.

In order to achieve the above object, a modular floor system according to the present invention is a modular floor system comprising a strut that absorbs impact and a joist that is coupled to the strut and supports a floorboard, And a bolt fastening hole formed vertically through the support plate; A support bolt threaded through the bolt fastening hole of the support plate; A support plate supported in close contact with the ground; A spring installed between the support plate and the support bolt; And a cylinder coupled to a lower portion of the support bolt or to an upper side of the support plate and surrounding the spring, wherein an impact applied at the upper portion is absorbed by the spring, the spring vertically moving within the cylinder surrounding the circumference The lateral tilting phenomenon can be suppressed.

Wherein a nut is coupled to a lower portion of the support bolt on an inner side and coupled to an upper portion of the cylinder on an outer side; And a support block inserted into the lower portion of the cylinder, wherein the lower portion is coupled to the support plate, and the upper portion is inserted into the lower portion of the cylinder. The spring is installed between the nut and the support block, The nut coupled to the lower portion compresses the spring and moves down while the cylinder coupled with the nut surrounds the spring and the support block.

In addition, the upper surface of the support bolt is provided with the adjustment groove, and the height of the support plate can be adjusted by inserting the tool into the adjustment groove and rotating the support bolt.

The support plate is made of a rubber material, and a bottom groove is formed on the bottom surface. An injection hole is formed so as to be connected from the bottom groove to the top. When the adhesive is injected through the upper portion of the injection hole, So that the support plate can be fixed to the ground.

In the modular floor system according to the present invention, the shock absorbing action is not made by using the anti-vibration rubber, but the shock is absorbed by a spring such as a coil spring or a gas spring. Therefore, it is possible to maintain a high shock absorption rate even when used for a long time.

At this time, since the cylinder always surrounds the spring when the compression is released, the spring can only be vertically moved. In other words, if an external impact is generated in an irregular direction with the spring exposed, compression and relaxation of the spring may cause the spring to tilt to the left or to the right. If the spring is repeatedly tilted, There is also a possibility. However, according to the present invention, when the spring is elastically moved, the cylinder always surrounds the circumference of the spring, so that only the vertical movement is possible without sagging. Therefore, there is a very low possibility of deformation or detachment of the spring due to the tilting of the spring.

Further, in the marble system according to the present invention, the support plate made of a rubber material is placed on the ground, and then the adhesive is injected into the injection hole to fill the bottom groove with adhesive to fix the entire support including the support plate. That is, a bolting operation for fixing the pillar to the floor is not necessary, and the working efficiency is improved.

In addition, the backing plate, made of soft rubber, minimizes floor swing with its own elasticity. That is, the support plate is fixed to the floor, but the left and right shakes such as an earthquake are absorbed by the rubber supporting plate, and the up and down shakes are caught by the spring. That is, in the marble system according to the present invention, the impact absorption rate can be increased by the combined action of the rubber supporting plate and the spring.

Also, it is necessary to adjust the floor height according to the characteristics of the installation site. In the present invention, the height of the support plate can be easily adjusted by inserting the tool into the adjustment groove of the support bolt exposed on the support plate. In other words, in the past, height adjustment has been required by inserting a tool under the bracket that supports the floorboard, so that the height adjustment operation is inconvenient. When the space under the floor is narrow, a tool such as a spanner may not be used at all. The upper part of the support bolt exposed on the support plate can be easily rotated so that the height adjustment can be smoothly carried out.

In addition, in the existing maritime system, long joists such as long joists are cut according to the site conditions. In the present invention, since the joists, joists, reinforcement bars and top plates are all standardized and manufactured in a module form, There is an advantage that it is convenient.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, some configurations which are not related to the gist of the present invention may be omitted or compressed, but the configurations omitted are not necessarily those not necessary in the present invention, and they may be combined by a person having ordinary skill in the art to which the present invention belongs. .

FIG. 1 is a perspective view for explaining a modular floor system (hereinafter referred to as a 'modular floor system' or a 'floor system') for absorbing impact using a spring according to an embodiment of the present invention. 1, a floor system 1 according to an embodiment of the present invention includes a strut 100 that absorbs impact, a joist 210 that is coupled to the strut 100 and supports the top plate 230, And includes a reinforcing bar 220. When a floorboard (not shown) is installed on the upper plate 230 in a state where the upper plate 230 is supported on the joist line 210 and the reinforcing bar 220, a floor covering such as a gymnasium or an auditorium can be constructed. Particularly, in the marble system 1 according to the embodiment of the present invention, since all the parts are standardized, the parts can be assembled as shown in FIG. 7 after the parts are moved to the construction site. This will be explained later.

Fig. 2 is a perspective view showing an enlarged view of a strut part in the modular floor system shown in Fig. 1, Fig. 3 is a view of removing the cylinder from the pillar of the modular floor system shown in Fig. 1, FIG. 5 is a view of the strut of the modular floor system shown in FIG. 1, and FIG. 6 is a side view of the spring in the modular floor system shown in FIG. And FIG.

As shown in FIGS. 2 to 6, the strut 100, which is fixed to the ground and supports the joist line 210 and the reinforcing bar 220, includes a support plate 110, a support bolt 120, a nut 130, 160, a support plate 180, a support block 170, and a coil spring 140.

The support plate 110 is provided to support the iron wire 210 and the reinforcement bar 220 and the guide protrusion 111 is formed on the upper portion to position the iron wire 210. In other words, the joist line 210 is formed by folding an elongated iron plate and protruding inwardly, and wings extending outward on both sides. The wings of the joist line 210 are supported on the support plate 110 when the guide protrusion 111 protruding upward from the support plate 110 is positioned in a space protruding above the inside of the wings of the joist line 210. At this time, the joist line (111) does not bias the joist line (210).

A plurality of long wire fastening holes 113 are formed in the support plate 110 and elongated holes 211 are formed in both wings of the long wire 210. Thus, when the bolt (not shown) is fastened to pass through the long hole 211 and the long wire fastening hole 113, the fastening plate 110 and the long wire 210 are coupled. The reason why the elongated hole 211 is formed in the joist line 210 is for convenience of construction. That is, if a hole is formed in the joist line 210 with the same size as the joining line 113 formed in the support plate 110, the fastening position must be accurately maintained during the fastening operation of the support plate 110 and the joist line 210. However, it is not necessary to precisely align the positions of the bolt fastening holes when fastening the joint line 210 and the support plate 110 by the elongated holes 211 formed in the joint line 210, so that the installation work is facilitated.

The reinforcing bar 220 is raised on the support plate 110 in a direction perpendicular to the joist line 210. In other words, referring to FIG. 1 showing a single module type floor system 1, in a state where the pillars 100 are positioned at four corners, the joists 210 are fixed to the support plate 110 in parallel at the upper and lower sides The reinforcing bars 220 are raised on the support plate 110 on the left and right sides. The reinforcement bar 220 may be bolted to the joint fastening hole 113 formed on the support plate 110 if necessary, in a manner similar to the joint line 210, with the inside thereof projecting upward and the wings bent on both sides. When the joist 210 and the reinforcement bar 220 are installed in the strut 100, the upper plate 230 can be placed on the wing of the joist 210 and the reinforcement bar 220.

On the other hand, since the upper plate 230 can be stably supported on the joist line 210 fixed to the support plate 110, the reinforcement bar 220 need not be fixed to the support plate 110. If the reinforcing bars 220 are not straddled between the two supporting plates 110, the reinforcing bars 220 can flex and react with each other in accordance with the contraction and expansion of the wood flooring (not shown). In other words, it can solve the rising phenomenon of wood flooring due to external moisture.

A bolt fastening hole 114 is formed so as to penetrate from the center of the upper portion of the guide protrusion 111 to the lower center portion of the extension block 112. A screw thread is formed inside the bolt fastening hole 114 so that the support bolt 120 passes through the bolt fastening hole 114 and is screwed. That is, the extension block 112 can be considered to have a configuration in which the thickness of the support plate 120 is extended to support the support bolt 120 firmly.

On the upper surface of the support bolt 120, an adjusting groove 121 into which a tool can be inserted is formed. That is, the support bolt 120 is completely threaded through the bolt fastening hole 114 of the support plate 110 so that the upper surface on which the control groove 121 is formed is exposed on the support plate 110. Therefore, when the support bolt 120 is rotated by inserting a tool such as a screwdriver into the adjustment groove 121, the height of the support plate 110 is adjusted.

A nut 130 is coupled to the lower portion of the support bolt 120 and an upper portion of the cylinder 160 is coupled to the periphery of the nut 130. Since the nut 130 and the cylinder 160 must always flow together, they are integrally formed in advance.

A support block 170 is seated on the center of a support plate 180 made of a rubber material and a bottom groove 182 is formed on the bottom surface as shown in FIG. And a plurality of injection holes 181 are formed so as to be connected from the bottom groove 182 to the upper portion of the support plate 180. Therefore, when the adhesive is injected through the upper part of the injection hole 181 while the support plate 180 is placed on the ground, the bottom groove 182 is filled with the adhesive, and when the adhesive is hardened, the support plate 180 is fixed to the ground. That is, in the present invention, it is not necessary to fix the support plate 180 to the ground by bolting to fix the support 100 to the ground, and it is possible to easily fix the support to the ground by merely injecting the adhesive into the injection hole 181 of the support plate 180 Can be achieved.

A support block 170 is seated in the center of the support plate 180. The upper portion of the support block 170 corresponds in size to the size of the nut 130. Accordingly, when the spring is positioned between the nut 130 and the support block 170, the upper and lower portions of the spring are in close contact with the bottom surface of the nut 130 and the upper surface of the support block 170, respectively. The shock absorbing springs have various types, and in FIGS. 1 to 7, the coil spring 140 is applied.

When the coil spring 140 is installed between the nut 130 and the support block 170, the cylinder 160 is inserted into the nut 130, The coil spring 140, and the support block 170, respectively. At this time, the cylinder 160 and the nut 130 are integrally formed, but the coil spring 140 and the support block 170 are not completely in contact with the cylinder 160.

The coil spring 140 is compressed by the force transmitted along the support bolt 120 and the nut 130 so that the coil spring 140 is lowered and the cylinder 130 coupled to the nut 130 160 are also lowered together with the coil spring 140 and the support block 170 wrapped around each other. That is, even if the coil spring 140 repeatedly performs the compression and relaxation actions, the coil spring 140 always maintains a state in which the cylinder 160 surrounds the coil spring 140 to protect the coil spring 140. Therefore, There is no occurrence of a phenomenon of swaying to the left or right. Therefore, the force due to the external impact can be uniformly absorbed by the coil spring 140.

FIG. 7 illustrates a plurality of module floor system 1 according to an embodiment of the present invention. That is, as shown in FIG. 1, the four stanchions 100 and the modular floor system 1 composed of the two seam lines 210, the two reinforcing bars 220 and the one upper plate 230 are arranged adjacent to each other The floor can be installed by connecting it. In this case, since the joist line 210 and the reinforcement bar 220 can place the upper plate 230 on both sides of the wing, the struts 100, the joists 210 and the reinforcement bars 220 can be shared have.

1 to 7 show that the coil spring 140 is applied as a spring for absorbing impact, but the gas spring 150 may be used for shock absorption as shown in FIG. That is, a gas spring 150 is installed between the nut 130 and the support block 170 by filling gas (air or nitrogen) in a closed bellows and using the elastic force, Can be produced.

As described above in detail, the floor system 1 according to the embodiment of the present invention has the following features.

A shock absorption rate can be maintained even if it is used for a long period of time because a spring such as the coil spring 140 or the gas spring 150 is used. At this time, when the spring is compressed and relaxed, since the cylinder 160 always surrounds the periphery of the spring, the spring can only be vertically moved. In other words, if an external impact is generated in an irregular direction with the spring exposed, compression and relaxation of the spring may cause the spring to tilt to the left or to the right. If the spring is repeatedly tilted, There is also a possibility. However, in the present invention, the cylinder 160 always surrounds the spring 160 when the spring 160 performs the elastic movement, so that the vertical movement is possible only without a side-to-side deviation. Therefore, there is a very low possibility of deformation or detachment of the spring due to the tilting of the spring.

In the marble system 1 according to the embodiment of the present invention, the support plate 180 made of a rubber material is placed on the floor, and then the adhesive is injected into the injection hole 181 to fill the bottom groove 182 with adhesive, It is possible to fix the entirety of the pillars 100 including the pillars 180. That is, a bolting operation for fixing the column 100 to the floor is not required, and the working efficiency is improved.

In addition, the support plate 180, which is made of soft rubber, has its own elasticity to minimize floor swing. That is, the support plate 180 is fixed to the floor, but the left and right shakes such as an earthquake are absorbed by the rubber supporting plate 180, and the up and down shakes are caught by the spring. That is, in the marble system 1 according to the present invention, the impact absorption rate can be increased by the combined action of the rubber supporting plate 180 and the spring.

In the present invention, by inserting a tool into the adjustment groove 121 of the support bolt 120 exposed on the support plate 110, the support plate 120 can be easily assembled with the support plate 120, Can be adjusted. In other words, in the past, height adjustment has been required by inserting a tool under the bracket that supports the floorboard, so that the height adjustment operation is inconvenient. When the space under the floor is narrow, a tool such as a spanner may not be used at all. The upper portion of the support bolt 120 exposed on the support plate 110 can be easily rotated to easily adjust the height.

However, in the present invention, the support 100, the joist 210, the reinforcement bar 220, and the top plate 230 are both made of the same material. Since it is standardized and manufactured in the form of a module, there is an advantage that it is convenient to move and assemble.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And additions should be considered as falling within the scope of the claims of the present invention.
