Description

The present invention provides a seismic-resistant structure when building a slab that is installed across a wall composed of the assembly-type block after the wall is formed using the assembly-type block during construction. The present invention relates to a seismic method for building slabs to obtain excellent slabs.

The earthquake-resistant design of a building is designed so that it can cope with disasters such as earthquakes and strong winds and other external forces transmitted to the building from outside. In general, a slab that structurally reinforces a column structure and a beam structure and a connecting portion between the column and the beam and forms a space bottom or a ceiling of the building has a form supported on an upper part of the beam structure.

Here, the beam structure and the slab are often constructed in one piece by placing concrete, but in such a construction structure, the seismic performance is weak, especially in the case of high-rise buildings, the structural safety. It is difficult to ensure seismic safety.

  In contrast to this, another method in the construction of earthquake-resistant buildings is that the slab is constructed on the top of the beam structure, and the seismic isolation can be used to buffer the vibration between the beam structure and the slab. There is a slab construction method having a structure in which a device (seismic device) is interposed.

However, in such conventional seismic slab construction methods, since the slab is constructed on the upper part of the beam structure, even if an earthquake resistant device having a buffer function is interposed between the beam structure and the slab, the vibration of the building In addition, the vibration and impact are transmitted to the slab through the column structure, the beam structure, and the seismic device when the impact occurs, and the slab stagnation phenomenon cannot be prevented.

In addition, since the slab is constructed on the upper part of the beam structure, when a seismic device having a buffer function is provided between the beam structure and the slab, there arises a problem that the height of the building is lowered.

In consideration of the above-mentioned problems, Korean Patent Registration No. 10-1404814 (announced 2014.06.12) discloses “Seismic Isolation Swing Slab Construction Method”. A support device is installed in which a suspension member that is suspended and supported so as to be relatively plane-movable is installed at a lower portion of the structure, and a floating coupling means that couples the suspension member to the slab and the beam structure is relatively movable. The suspension member has a bar shape penetrating the slab and the beam structure so that the suspension member can freely move, and a coupling portion to which the floating coupling means is coupled to both end regions in the lengthwise direction is formed. The floating coupling means includes a pair of floating support bodies each having a through hole through which both side end regions of the suspension member pass movably, and the coupling portion of the suspension member that has passed through both the floating support bodies. In Is engaged, it discloses a seismic isolation swing slab construction method which comprises a floating coupling member supported so as to be relatively loose with respect to the floating support.

In the case of the above-mentioned patent, it is possible to expect the effect of minimizing the building height of the building and allowing the slab to be suspended in a relatively plane-movable manner. There is a problem that cannot be secured.

Also, Korean Patent Publication No. 10-2008-005717 discloses a “slab seismic structure”. This technique is a basic structure of a pillar member and a beam, and is one side surface of a slab installed on the beam. And an elastic member interposed in a space between the pillar member and the pillar member, wherein the elastic member is selected from rubber, plastic, wood and polystyrene foam, The content of being installed along the circumference | surroundings, being interposed between a slab and a beam is disclosed.

However, in the case of the above-described technology, impact resistance and seismic resistance due to the vibration of the slab using an elastic member selected from any one of rubber, plastic, wood, and polystyrene foam specified as the elastic member. It is impossible to secure sufficient.

In addition to the technology described above, in the case of buildings using PC slabs, in order to ensure earthquake resistance, composite construction methods such as PRC (Precast Reinforced Layer Construction Method) using half slabs (Half PC Slab) are implemented. Has been.

In the PRC compounding method, PC buildings such as PC pillars, PC beams, and half slabs manufactured at the factory are transported and lifted by converting the building of reinforced concrete ramen (Rahmen) structure to PC (Precast Concrete). After assembling, topping concrete is placed on site at the joint between the members and the upper part of the half slab to integrate the structure.

However, in the construction of the current building, after constructing PC members at the construction method by the site placement or at the factory, the work is transferred from the site to work, and the building is constructed using the assembly block directly at the site. In many cases, it is built by a construction method that applies construction.

Korean Patent Registration No. 10-1365486, which has been filed and registered by the present applicant, “Method for Producing Seismic Assembly Type Outer Block Unit” or Korean Patent Registration No. 10-1365487, “Assembling Type Block Unit for Earthquake Resistance” and Korean Patent Registration No. 10-1365485 “Seismic assembling type block unit structure and method of constructing seismic wall using this” etc. Unlike the construction method, the construction period will be dramatically shortened, and the disclosed construction methods will be gradually developed in consideration of the completeness and stability of construction and become a realistic construction method. The fact is that it has been adopted.

However, it is difficult to secure the earthquake resistance against the slab even if the building wall is constructed using the assembly type earthquake resistant block. As a supplement to this, it is conceivable to apply the beam structure and slab described above as seismic isolation devices. However, as pointed out in the above-mentioned problems, the problem of lower layer height should be avoided. Can not.

Therefore, the present invention overcomes the problems presented by the above-mentioned other technologies, and in particular, enables the seismic resistance of slabs to be secured in a building constructed using an assembly-type block. Has its purpose.

In addition, the present invention is seismic-resistant so that a direct impact transmission can be mitigated by using an elastic means for a connection region between a wall body and a slab provided by an assembly type block. However, there is another object to enable the role of blocking the noise, which can prevent the shock noise transmitted from the slab from being transmitted to the lower layer.

In order to achieve the above-mentioned object, the present invention

The object of the present invention can be achieved by comprising a slab side end finishing step in which a separation portion between the side end face of the slab and the inner peripheral surface of the outer wall is sealed.

Therefore, the present invention overcomes the problems presented by the above-mentioned other technologies, and can particularly secure the earthquake resistance of the slab in a building constructed using an assembly-type block. While making the connection area between the wall body and the slab provided by the assembly type block elastically used so that direct shock transmission can be mitigated, It is possible to expect an effect of enabling the role of blocking noise, which can prevent shock noise transmitted from the slab from being transmitted to the lower layer.

Outer wall installation stage-S100

In the present invention, after constructing the outer wall body 10 and the inner wall body 20 using an assembly type block, the slab 100 supported by the upper surface of the inner wall body 20 is installed and constructed, and is earthquake resistant when a disaster such as an earthquake occurs. In this stage, a process of installing and constructing the outer wall 10 is performed as a stage before installing the side end elastic member. At this time, as shown in FIGS. 1 to 2, it is preferable that the outer wall body 10 is also constructed by an assembly type block for ensuring the earthquake resistance in the outer wall body 10 itself.

For example, the configuration of the outer wall 10 is the same as the configuration of the exterior block 11 and the core block 12 coupled to the interior of the exterior block 11 disclosed in Korean Patent Registration No. 10-1365485 of the present applicant. However, a plurality of block hollow portions 11 a are formed inside the exterior block 11, and a semi-hollow portion 11 b is formed at each side end portion, and by coupling between the end portions of the exterior block 11. The semi-hollow part 11b forms a block hollow part in a completed form.

Using the exterior block 11, the side end portion is disposed, and the core block 12 is inserted and joined to the block hollow portion 11 a side of the exterior block 11 so as to be perpendicularly connected to the block 11. An elastic tool 13 cut in the length direction and having elastic force is forcibly inserted into the arc-shaped elastic tool insertion hole 12 a formed at the four corners of the core block 12, and the core block 12, the exterior block 11, Thus, the seismic power transmitted from the exterior block 11 by the elastic member 13 can be canceled.

The outer wall body 10 constituting the entire building is constructed by mutual coupling of the exterior block 11, the core block 12, and the elastic member 13 having the above-described configuration.

On the other hand, as shown in FIG. 1, FIG. 2, or FIG. 4, when the outer wall 10 is formed by the exterior block 11 and the core block 12, blocks having different standards from the exterior block 11 are used at the four corners of the building. And can be constructed.

For example, the in-corner block 14 can be adopted in order to give the building strength and stress corresponding to the load.

Of course, whether or not the in-corner block 14 is adopted may or may not be adopted depending on the overall load of the building to be constructed and the structural design variables.

The in-corner block 14 has a substantially “┓” shape, and the lower end of the in-corner block 14 is fixed to the ground with the H beam and each pipe pipe vertically inserted in the center. It has a structure to make it.

Similarly to the exterior block 11, the in-corner block 14 is also formed with a block hollow portion 14a and a semi-hollow portion 14b. In the block hollow portion 14a of the in-corner block 14, an in-corner core member 15 made of an H-beam or each pipe pipe is installed inside in order to further increase the rigidity.

The block hollow portion 14a formed at the center of the in-corner block 14 is fixedly coupled at its end to the bottom surface after the in-corner core member 15 is inserted.

At the same time, the complete hollow part side formed by the semi-hollow part 11b of the exterior block 11 in contact with the semi-hollow part 14b of the in-corner block 14 is laminated and coupled using the core block 12 and the elastic tool 13. The outer wall 10 of the building is formed as a whole.

Side end elastic member installation stage-S200

In the side end elastic member installation step (S200), when the beam 110 supported by the upper surface of the inner wall body 20 is formed after the construction of the inner wall body 20 constituting the layer height is completed, the beam 110 side It means a process of installing the side end elastic member 120 at the side end of the beam 110 in an operation of connecting the end and the outer wall body 10.

As described above, the construction of the outer wall body 10 that forms the basic frame of the building and forms the outer wall is performed through the outer wall body installation step (S100) described above, and at the same time, the height of the building is formed. In this stage, before installing the slab 100, first, the outer block 11 constituting the outer wall body 10 and the side end elasticity on the side end side of the beam 110 for constituting the slab 100 are installed. The member 120 is formed.

Here, when the outer wall 10 is installed, a beam 110 for supporting the slab 100, an H beam or each pipe pipe installed vertically in an intermediate region of the outer wall 10, and an end portion thereof are provided. Connected.

When the outer wall body 10 is configured, the inner corner block 14 is positioned on the inner corner side, and the outer wall body 10 is installed on the side of the outer wall body 10 by the combination of the exterior block 11 and the core block 12. Each tube pipe 11c is vertically inserted and fixed to the block hollow portion 11a side of the exterior block 11 located at a central region of 10 or spaced apart at equal intervals, but the end of the beam 110 and each tube pipe 11c are fixed. The connection work between is performed.

That is, as shown in FIG. 8, a flat plate 11d is welded and fixed to the upper surface of each pipe pipe 11c, and the end of the beam 110 is seated on the upper surface side of the flat plate 11d. Each pipe pipe 11c ′, in which the flat plate 11d is welded and fixed to the lower end, is also connected and fixed to the upper side on the end side of 110.

At the same time, the flat plate 11d and the beam 110 are connected by bolts.

Thus, when the end connection work between each pipe pipe 11c and the beam 110 is completed, the side end elastic members 120 are formed on both side surfaces of the end of the beam 110, and the end of the beam 110 is formed. The transmission of seismic power between the side and the outer wall 10 can be absorbed and blocked.

Here, as shown in FIG. 10, the side end elastic member 120 is formed by welding and fixing a shape steel 121 to both ends of the beam 110 and inserting a slab elastic tool 122 inside the shape steel 121. The slab elastic member 122 is brought into contact between the end portion side of 110 and the outer wall 10.

As shown in the drawing, the slab elastic member 122 forms an incision portion 122a that is entirely incised along the length direction of the slab elastic device 122, and an end portion forms a tapered surface 122b in an inward direction. A tapered portion 122c is formed, and a plurality of tapered incision grooves 122d for incising the tapered portion 122c at equal intervals are formed to have elastic pieces 122e.

By providing elastic properties while avoiding direct contact between the beam 110 and the exterior block 11 forming the outer wall body 10 by the side end elastic member 120 having such a slab elastic member 122, the seismic force from the outside is provided. When the seismic power due to the earthquake or the like is provided, it is possible to ensure the earthquake resistance of the entire building by easily canceling this, and the side end elastic member installed at this stage 120 can ensure earthquake resistance by absorbing the slab's horizontal seismic power.

Upper surface elastic member installation stage; S300

The upper surface elastic member installation step (S300) in this step is a step for installing an elastic member on the upper surface of the beam 110 installed in the side end elastic member installation step (S200). On the top surface, a deck plate, a dry heating panel, a bottom finish panel, etc. are laminated and processed, but this includes the deck plate, dry heating panel, bottom finish panel, etc. This is to prevent transmission to the slab 100.

For this purpose, the upper elastic member 130 has a configuration as shown in FIG. 9, and is configured by vertically separating the upper flat plate 131 and the lower flat plate 132 at every position separated from the upper surface of the beam 110 at equal intervals. The spring reinforcing member 133 that penetrates the upper and lower flat plate plates 131 and 132 is formed. The spring reinforcing member 133 includes a spring 134 so that the upper and lower flat plate plates 131 and 131 are inserted. The vibration transmitted from the beam 110 is canceled by the spring 134 while maintaining the separated state of the plate 132.

As described above, the seismic power transmitted from the outer wall body 10 is stabilized by the lateral pressure that can withstand the seismic power by the slab elastic member 122 that constitutes the side end elastic member 120 of the beam 110 that supports the slab 100. The seismic power transmitted vertically can not be canceled out.

Therefore, the vertical elastic force 130 transmitted through the beam 110 can be canceled by adopting the upper elastic member 130 in the present invention in order to cancel the seismic power generated in the vertical direction.

That is, the vertical seismic power provided to the slab 100 in the building can be offset and buffered by the facility of the upper surface elastic member 130 at this stage, and the seismic resistance due to the absorption of the vertical seismic power can be ensured.

Therefore, the side elastic member 120 and the upper elastic member 130 installed and constructed in the side end elastic member installation step (S200) and the upper elastic member installation step (S300) described above absorb and mitigate left and right and vertical seismic power of the slab. Seismic resistance.

Slab formation stage-S400

When the installation of the upper elastic member 130 is completed, a slab forming step (S400) is performed in which the deck plate 200, the dry heating panel 300, and the bottom finish panel 400 are sequentially installed on the upper surface of the upper elastic member 130.

The construction method of installing the deck plate 200, the installation process of the dry heating panel 300, the installation method of the bottom finish panel 400, and the like are well-known techniques and will not be described in detail in the present invention.

On the other hand, as described above, the slab 100, which is completed by being processed by the deck plate 200, the dry heating panel 300, and the bottom finish panel 400, is entirely separated from the inner surface of the outer wall body 10. Therefore, when an earthquake or an impact from an external force is transmitted to the building, the seismic power can be avoided from being directly transmitted to the slab 100 side. Can be offset by the side end elastic member 120 and the top elastic member 130.

Slab side edge finishing stage-S500

This step is a step of sealing a separation portion between the side end surface of the slab 100 formed by the slab formation step (S400) and the inner peripheral surface of the outer wall body 10, and the slab 100 is processed. When the installation of is completed, the slab 100 and the inner peripheral surface of the outer wall body 10 are kept separated.

If such a separated state is maintained, the lateral force in the seismic power transmitted to the building by an earthquake or the like as described above can be canceled by the side end elastic member 120 or the like. , May be vulnerable to stuttering between layers.

Therefore, in order to prevent such interlayer noise, after the slab 100 is completed, a separation portion between the side surface of the slab 100 and the inner peripheral surface of the outer wall body 10 is finished by silicone treatment or epoxy molding treatment. It is processed.

In consideration of the fact that the interlayer noise can be blocked by such a finishing process, and the transmission form of the interlayer noise that is generally generated is transmitted along the pillars and the wall body, Of course, it is possible to completely eliminate the phenomenon in which the noise is transmitted using each member, that is, the outer wall body 10 and the inner wall body 20 as a transmitter, or the separation space (or the space between the slab 100 and the outer wall body 10). By the finishing process of the separation part, the transmission path of the stuttering can be completely blocked and eliminated.

As described above, the present invention has been described with reference to the limited embodiments and drawings. However, the present invention is not limited to the above-described embodiments, and those having ordinary technical knowledge in the field to which the present invention belongs. Of course, various modifications and variations can be made from the contents described above.

Accordingly, the technical idea of the present invention should be understood from the claims described below, and it is obvious that equivalent or equivalent modifications also belong to the category of the technical idea of the present invention.
