Description

TECHNICAL FIELD

The present invention relates to a seismic construction method of a slab of a building, which is capable of obtaining a slab having high seismic resistance, when, during construction of a building, walls are formed using prefabricated blocks and a slab is installed to cross the walls consisting of the prefabricated blocks.

BACKGROUND ART

A seismic design of a building is made to counteract disasters such as earthquakes or strong winds or external forces transferred from the outside to the building. Generally, a slab which structurally reinforces a pillar structure, a beam structure, and combined parts of pillars and a beam and which forms the floor or the ceiling of the building is supported on an auxiliary cast.
Generally, the beam structure and the slab are integrally constructed by depositing concrete. However, a structure constructed as described above has low seismic performance, and particularly, the structural stability of a high-rise building is not easy to secure. Accordingly, it is difficult to guarantee seismic safety.
In contrast, in a slab construction method which is one of earthquake-resistant building construction methods, a slab is constructed on a beam structure, and a vibration isolation device (an earthquake-resistant device) is interposed between the beam structure and the slab to buffer vibration.
However, in such conventional earthquake-resistant slab construction methods, a slab is constructed on a beam structure. Thus, even if an earthquake-resistant device having a buffer function is interposed between the beam structure and the slab, when vibration and impact are applied to a building, the vibration and the impact are transferred to the slab via a pillar structure, the beam structure, and an earthquake-resistant device. Accordingly, shaking of the slab cannot be prevented.
Furthermore, since the slab is constructed on the beam structure, a floor height of a building decreases when the earthquake-resistant device having the buffer function is provided between the beam structure and the slab.
To address the above problems, a “Construction Method of a Vibration Isolation Swing Slab” is disclosed in Korean registered patent No. 10-1404814 (Publication Date: Jun. 12, 2014). This patent discloses a construction method of a vibration isolation swing slab, the construction method including installing a suspension member configured to suspend and support a slab below a beam structure such that the slab is movable relative to a plane, and installing a support device by installing a movable coupling means configured to couple the suspension member to the slab and the beam structure to be movable relative to the slab and the beam structure. The suspension member has a rod shape to movably pass through the slab and the beam structure, and includes coupling parts on opposite end regions thereof in a lengthwise direction to be coupled to the movable coupling means. The movable coupling means includes a pair of movable supporters having through-holes through which the opposite end regions of the suspension member may movably pass, and a movable coupling member coupled to the coupling parts of the suspension member passing through the pair of movable supports to be movably supported with respect to the pair of movable supporters.
According to the above-described patent, decrease in floor height of a building may be minimized and a slab may be suspended and supported to be movable relative to a plane, but seismic resistance to vertical shock is not secured.
A “Slab Earthquake-resistant Construction” is disclosed in Korean Patent Laid-Open Publication No. 10-2008-0057517. This technique discloses that, in a basic structure including a pillar member and a beam, an elastic member is provided in a space between a side surface of a slab installed at the beam and a side surface of the pillar member, is formed of a material selected from among rubber, plastic, wood, and Styrofoam, is installed around the pillar member, and is interposed between the slab and the beam.
However, according to this technique, it is impossible to secure high impact resistance and high seismic resistance of the slab to vibration when the elastic member formed of rubber, plastic, wood, or Styrofoam is used.
In addition, in the case of a building using a precast concrete (PC) slab, a precast reinforced-layer construction (PRC) hybrid method using a half slab (a half PC Slab) is performed to secure seismic resistance.
In the PRC hybrid method, a building having a ferroconcrete Rahmen structure is precast-concrete (PC), and PC members, such as a PC pillar, a PC beam, and a half slab, which are manufactured in a factory, are transferred to a construction site, lifted, and assembled together, and topping concrete is deposited at interfaces between the PC members and on the half slab at the construction site, thereby integrally forming elements of a structure.
However, generally, buildings today have been constructed by a technique for directly constructing a building using prefabricated blocks on a construction site rather than an on-the-spot deposition method or rather than by constructing a building by depositing PC members in a factory and transferring them to a construction site.
Korean registered patent No. 10-1365486, entitled “Earthquake-Resistance Assembling Exterior Block Unit Manufacturing Method”, Korean registered patent No. 10-1365487, entitled “Earthquake-Resistance Assembling Unit”, and Korean registered patent No. 10-1365485, entitled “Earthquake-Resistance Assembling Block Unit Structure and Construction Method of Earthquake-Resistance Wall” which have been filed and registered by the applicant of the present invention have been disclosed. Thus, building construction methods have been developed and employed as practical construction methods to significantly decrease a building construction period and in consideration of degrees of completion and stability of construction, etc., rather than constructing a building using only the PC members or the on-the-spot deposition method.
However, even if walls of a building are constructed using prefabricated earthquake-resistant blocks, it is difficult to secure slabs having seismic resistance. To address this problem, the vibration isolation device may be applied to the beam structure and the slab described above but decreasing of a floor height of a building cannot be avoided as described above.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The terms or expressions used in the present specification and the claims should not be construed as being limited to as generally understood or as defined in commonly used dictionaries, and should be understood according to the technical idea of the invention, based on the principle that the inventor(s) of the application can appropriately define the terms or expressions to optimally explain the invention. Thus, the embodiments set forth in the present specification and drawings are merely exemplary embodiments of the present invention and do not completely represent the technical idea of the present invention. Accordingly, it would be obvious to those of ordinary skill in the art that the above exemplary embodiments are to cover all modifications, equivalents, and alternatives falling within the scope of the invention at the filing date of the present application.
The present invention provides a seismic construction method of a slab of a building, in which a building is constructed using prefabricated blocks, and particularly, prefabricated blocks having seismic resistance.
FIG. 1 illustrates a process performed according to the present invention in a sequential manner, the process including installing side elastic members between a beam supported on an upper end of an inner wall and an external wall (S100), installing a top elastic member between a deco plate installed on an upper surface of the beam and the beam to absorb vertical vibration (S200), forming a slab to complete the slab (S300), and finishing side surfaces of the slab by finishing external walls which are in contact with outermost parts of the slab (S400).
Installation of External Wall—S100
According to the present invention, after an external wall 10 and an inner wall 20 are constructed using prefabricated blocks, a slab 100 is installed to be supported on an upper surface of the inner wall 20 to secure seismic resistance when a disaster such as an earthquake occurs. This operation is performed to construct the external wall 10, prior to installation of a side elastic member. The external wall 10 is preferably constructed using a prefabricated block to secure seismic resistance thereof as illustrated in FIGS. 1 and 2.
For example, the structure of the external wall 10 is the same as that obtained by combining an exterior block 11 and core blocks 12 combined with the inside of the exterior block 11, disclosed in Korean registered patent No. 10-1365485 of the present applicant. A plurality of hollow block parts 11 a is formed in the exterior block 11, and semi-hollow parts 11 b are formed at side ends of the exterior block 11. When ends of exterior blocks 11 are combined with each other, the semi-hollow parts 11 b form a completed form of a hollow block part.
A side end part of the external wall 10 is provided using the exterior blocks 11 described above, core blocks are vertically inserted into and combined with the hollow block parts 11 a of the exterior blocks 11. Then, elastic pieces 13 which are cut in a lengthwise direction and having elasticity are enforcedly inserted into elastic-piece insertion holes 12 a each having a circular arch shape and formed at four corners of each of the core blocks 12 to avoid direct contact between the core blocks and the exterior blocks 11 and to compensate vibration, which may be transferred from the exterior blocks 11, using the elastic pieces 13.
The external walls 10 of a whole building are constructed by combining the exterior blocks 11, the core blocks 12, and the elastic pieces 13 configured as described above.
As illustrated in FIG. 1, 2 or 4, when the external wall 10 is formed by the exterior blocks 11 and the core blocks 12, four corners of the building may be constructed using blocks having a different standard from that of the exterior blocks 11.
For example, in-corner blocks 14 may be employed to apply stress corresponding to the strength and weight of the building.
Whether the in-corner blocks 14 are employed may vary according to the total weight of the building to be constructed and parameters of the design of the structure of the building.
Each of the in-corner blocks 14 has a roughly ‘¬’ shape and is configured such that a lower end part thereof is fixed on the ground in a state in which an H-beam or a square pipe is vertically inserted into a center portion thereof.
Similar to the exterior blocks 11, a hollow block part 14 a and semi-hollow parts 14 b are formed at the in-corner block 14. An in-corner shim member 15 such as an H-beam or a square pipe is installed in the hollow block part 14 a of the in-corner block 14 to increase the hardness of the in-corner block 14.
The hollow block part 14 a formed at a center of the in-corner block 14 is configured such that, after the in-corner shim member 15 is inserted thereinto, an end part of the in-corner shim member 15 is fixedly coupled to a bottom surface thereof.
Furthermore, the core block 12 is stacked on and combined, using the elastic piece 13, with a whole hollow part formed by the semi-hollow parts 11 b of the exterior blocks 11 which are in contact with the semi-hollow parts 14 b of the in-corner block 14, thereby forming the external wall 10 of the building.
Installation of Side Elastic Member—S200
The forming of the side elastic member (S200) is a process of installing side elastic members 120 at side ends of a beam 110 during connection of the side ends of the beam 110 and the external wall 10 when the beam 110 supported on the upper surface of the inner wall 20 is formed after construction of the inner wall 20 forming a floor height.
As described above, the external walls 10 which form a basic frame and outer sides of the building are constructed through the forming of the external wall (S100) described above. At the same time, the slab 100 forming a floor height of the building is installed. In this operation, the side elastic members 120 are formed at side ends of the exterior blocks 11 forming the external wall 10 and the beam 110 forming the slab 100, prior to installation of the slab 100.
Here, when the external wall 10 described above is installed, the beam 110 supporting the slab 100 and end parts of an H-beam or a square pipe vertically installed in an intermediate region of the external wall 10 are combined with one another.
When the external wall 10 is configured, the in-corner block 14 is located at the in-corner thereof and sides of the external wall 10 are formed by combination of the exterior blocks 11 and the core blocks 12. The square pipe 11 c is vertically inserted and fixed into either a center region of the external wall 10 or each of the hollow block parts 11 a at the locations on the exterior block 11 which are spaced the same distance from each other, thereby coupling an end part of the beam 110 and the square pipe 11 c
That is, as illustrated in FIG. 8, a flat plate 11 d is fixed on an upper surface of the square pipe 11 c by welding. An end part of the beam 110 is placed on an upper surface of the flat plate 11 d. Thereafter, a square pipe 11 c′, a lower end of which is fixed by the flat plate 11 d by welding, is coupled to and fixed on the end part of the beam 110.
Furthermore, the flat plate 11 d and the beam 110 are coupled to each other via a bolt.
As described above, when coupling of the square pipes 11 c and end parts of the beams 110 is completed, the side elastic members 120 are formed at opposite side surfaces of the beams 110 to absorb and block vibration transmitted between the end parts of the beams 110 and the external wall 10.
Here, as illustrated in FIG. 10, in the side elastic member 120, shape steels 121 are fixed at opposite end parts of the beam 110 by welding and slab elastic pieces 122 are inserted into the shape steels 121 to bring the slab elastic piece 122 into contact between the end parts of the beam 110 and the external wall 10.
As illustrated in the drawings, the slab elastic piece 122 includes a cut part 122 a which is cut as a whole along a lengthwise direction of the slab elastic piece 122, a tapered part 122 c provided at an end part thereof to form a tapered surface 122 b in an inward direction, and a plurality of taper cut grooves 122 d for cutting the tapered part 122 c at uniform intervals to form elastic parts 122 e.
Due to the side elastic members 120 each including the slab elastic piece 122 described above, the beam 110 and the exterior blocks 11 forming the external wall 10 may be prevented from being in direct contact with each other and elasticity may be provided. Thus, when vibration is applied from the outside or due to an earthquake or the like, the vibration may be easily compensated and thus seismic resistance of the whole building may be secured. Seismic resistance may be secured since impact due to horizontal vibration of the slab may be absorbed by the side elastic members 120 installed in this operation.
Installation of Top Elastic Member—S300
In installation of the top elastic member (S300), the top elastic member 130 is installed on the upper surface of the beam 110 installed through the forming of the side elastic member (S200) described above. Generally, a decorative plate, a dry heating panel, a floor finishing panel, etc. are stacked on the upper surface of the beam 110 to prevent vibration or the like from being transferred from the beam 110 to the slab 100 including the decorative plate, the dry heating panel, the floor finishing panel, etc.
To this end, as illustrated in FIG. 9, the top elastic member 130 has a structure in which upper and lower flat plates 131 and 132 are vertically provided to be spaced apart from each other at each of locations on the upper surface of the beam 110 which are spaced the same distance from each other, a spring reinforcement tube 133 is formed to pass through the upper and lower flat plates 131 and 132, and a spring 134 is provided in the spring reinforcement tube 133. Accordingly, vibration which may be transferred from the beam 110 may be compensated for by the spring 134 while the upper and lower flat plates 131 and 132 are maintained spaced apart from each other.
Vibration transferred from the external wall 10 may be compensated for by lateral pressure applied by the slab elastic piece 122 of the side elastic member 120 of the beam 110 supporting the slab 100 and thus stability may be secured as described above, but vibration transferred in a vertical direction cannot be compensated for.
Accordingly, in order to compensate for vibration generated in the vertical direction, the top elastic member 130 according to the present invention may be employed and a force transferred vertically via the beam 110 may thus be compensated for.
That is, vertical vibration which may be applied to the slab 100 of the building may be compensated for and buffered by the top elastic member 130 installed in this operation. Accordingly, impact due to vertical vibration may be absorbed and thus seismic resistance may be secured.
Accordingly, horizontal and vertical vibration of the slab may be absorbed or lessened by the side elastic members 120 and the top elastic member 130 installed and constructed through the installation of the side elastic member (S200) and the installation of the top elastic member (S300), thereby securing seismic resistance.
Forming of Slab—S400
After installation of the top elastic member 130 is completed, forming of a slab (S400) is performed by sequentially installing a decorative plate 200, a dry heating panel 300, and a floor finishing panel 400 on the top elastic member 130.
A method of installing the decorative plate 200, a method of installing the dry heating panel 300, a method of installing the floor finishing panel 400, etc. are well-known techniques and thus are not described in detail here.
All outer surfaces of the slab 100 completed by constructing the decorative plate 200, the dry heating panel 300, and the floor finishing panel 400 are spaced apart from inner side surfaces of the external wall 10. Thus, when impact from an earthquake or external force is transferred to a building, vibration due to the impact may be prevented from being directly transferred to the slab 100. As described above, the transferred vibration may be compensated for by the side elastic members 120 and the top elastic member 130.
Finishing of Side Ends of Slab—S500
This operation is an operation of finishing, by sealing, separated parts of side surfaces of the slab 100 formed through the forming of the slab (S400) and an inner circumferential surface of the external wall 10. After the installation of the slab 100 is completed, the slab 100 and the inner circumferential surface of the external wall 10 are maintained spaced apart from each other.
When the slab 100 and the inner circumferential surface of the external wall 10 are maintained spaced apart from each other, lateral force among vibrations transferred to the building due to an earthquake or the like may be compensated for by the side elastic members 120 or the like as described above, but interlayer noise may not be compensated for.
Thus, in order to block such interlayer noise, after the slab 100 is completed, the separated parts of the side surfaces of the slab 100 and the inner circumferential surface of the external wall 10 are finished by silicone or epoxy molding.
Interlayer noise may be blocked by finishing the separated parts of the side surfaces of the slab 100 and the inner circumferential surface of the external wall 10 as described above. When it is taken into account that generated interlayer noise is generally transferred via pillars or walls, transfer of noise through the members according to the present invention, i.e., the external walls 10 and the inner walls 20, may be completely blocked. Furthermore, a separated space between (or separated parts of) the slab 100 and the external wall 10 may be finished and thus noise transfer paths may be completely blocked or eliminated.
While the present invention has been described with respect to exemplary embodiments and drawings, the present invention is not limited to these embodiments and various changes and modifications may be made therein by those of ordinary skill in the art.
Accordingly, the scope of the present invention should be defined by the appended claims, and it would be obvious to those of ordinary skill in the art that other equal or equivalent modifications thereto fall within the scope of the invention.
