Description

Seismic reinforcement of school buildings and relief structures for easy emergency evacuation in the event of an earthquake

[0001] The present invention relates to earthquake-resistant reinforcement of school buildings and to a rescue structure that facilitates emergency evacuation in the event of an earthquake, and more specifically, to earthquake-resistant reinforcement of school buildings and a rescue structure that facilitates emergency evacuation in the event of an earthquake, which can be applied to both existing and newly constructed schools, and which can play a role in preventing collapse by dissipating seismic energy in the event of an earthquake, while facilitating emergency evacuation by floor in the event of an earthquake.

[0002]

[0003] Earthquake loads are a natural phenomenon that is instantaneous and difficult to predict in advance, and they cause severe damage to buildings, especially concrete buildings, that are poorly designed for earthquake resistance and seismic control. In recent years, many young students have died in school building collapses due to earthquakes in Japan, Turkey, Pakistan, and China, causing great shock.

[0004] The classroom is the fundamental space in school buildings. Because lighting and ventilation are crucial for classrooms, the exterior walls facing the outside are comprised of a waist wall and a partition wall, with windows located within the partition wall.

[0005] In addition, in reinforced concrete school buildings, columns for supporting the load of the waist wall must be placed in appropriate locations, and columns must not be located in the center of the basic module so as not to obstruct the view of students when looking at one classroom as shown in Fig. 1.

[0006] Accordingly, reinforced concrete buildings such as schools are designed to be safe because the columns simultaneously receive axial force and lateral load due to the weight when an earthquake load is applied, but columns that are not designed to withstand earthquakes do not have a high resistance to lateral loads, so bending failure or shear failure due to lateral loads can occur. Shear failure induces sudden destruction of the columns supporting the structure, which can cause the collapse of the structure and cause casualties.

[0007] Therefore, in order to prevent building collapse and casualties, it is necessary to dissipate seismic energy by improving the shear strength of columns expected to undergo shear failure when an earthquake occurs, thereby inducing ductile failure rather than brittle failure, that is, ductile behavior followed by bending failure.

[0008] In addition, in the event of an earthquake, even if evacuation was conducted, many people would move to each floor, so there was a possibility of a safety accident occurring during the evacuation process. Therefore, the foundation work was carried out in a space independent from the school building, and a structure that could be evacuated separately from the school building in the event of an earthquake was needed.

[0009] Related prior art includes Patent Registration No. 10-1404572 (Title of the invention: Seismic reinforcement method using wing walls of school buildings), Patent Application No. 10-2012-0079452 (Title of the invention: Rooftop structure of a building with a structure for evacuation of people installed), and Patent Application No. 10-2017-0111668 (Title of the invention: Fire evacuation facility for high-rise buildings).

[0010] The above prior patent suggests a method for earthquake-resistant reinforcement using the wing walls of school buildings, but it is difficult to say that sufficient earthquake-resistant reinforcement has been provided because the cross-shaped beams, which play a key role in the event of an actual building collapse, are not subject to earthquake-resistant reinforcement, and it is difficult to realistically apply evacuation structures and facilities to school buildings.

[0011]

[0012]

[0013] Accordingly, the present invention recognizes the above problems and proposes a solution thereto, and the purpose is to provide a structure for earthquake reinforcement and relief that facilitates emergency evacuation in the event of an earthquake by providing a temporary shelter on each floor, while contributing to the prevention of collapse by dissipating seismic energy in the event of an earthquake, and that can be applied to existing school buildings.

[0035] Hereinafter, the present invention will be described in detail with reference to the attached drawings and preferred embodiments.

[0036] First, the earthquake-resistant reinforcement of the school building and the rescue structure (S) that facilitates emergency evacuation in the event of an earthquake are largely constructed as shown in FIGS. 1 and 2 as an independent form buried in the ground surface on one side of the school building, and are composed of a foundation (100) having a plurality of joint fixing parts (120) to which the main support (200) is connected, a main support (200) that is connected and fixed in one or more stages in the upper direction of the foundation (100), and an auxiliary support (300) that is configured in a detachable form on the side of the main support (200) and is introduced into the school building to support the vertical beam (20) and prevent falling objects of collapsed objects.

[0037] At this time, the base part (100) is provided with a base plate (110) formed in one of a polygonal, circular, or oval shape as shown in FIGS. 1 and 2.

[0038] At the top of the above base plate (100), a joint fixing part (120) is formed to facilitate fastening after fitting and joining with the lower side of the main support (200), and at the same time, a number of joining holes (124) are formed on the outside of the joint fixing part (120), so that a plurality of base supports (130) that are fastened and joined through bolts (410) and nuts (420) after fitting and joining the upper and lower parts are fused and fixed.

[0039] On the lower side of the above foundation support (130), a reinforcing block (140) is fused and fixed to connect and fix the foundation support (130) and base plate (110) to improve the fixing force of the foundation support (120) and to perform the function of a reinforcing bar when pouring concrete to improve cohesion.

[0040] Between the above foundation supports (130), horizontal supports (150) are fused and fixed to improve the fixing force of the foundation supports (130) by connecting and fixing them together, and at the same time, they perform the function of reinforcing bars when pouring concrete to improve cohesion.

[0041] As shown in FIG. 2, the above joint fixing member (120) has symmetrical insertion protrusions (121) formed at a certain interval so that the lower surface of the main support (200) can be inserted and fixed, and at the same time, an 'H'-shaped fixing cross-section (122) is formed to prevent the lower surface of the main support (210) from further downward movement while in contact, and a curved opening (123) is formed on the upper side of the insertion protrusion (121) so that the lower surface of the main support (200) is not interfered with when inserted.

[0042] As described above, when the lower surface of the main support (200) is secured to the mounting surface (122), the connection can be fixed using a bolt (410) and a nut (420), and this joint fixing part (120) is formed each time the main support (200) is connected one by one.

[0043] The above-mentioned main support (200) is formed with a fastening groove (210) so that it can be fixed by a joint connection in the upper direction at least once through a joint fixing member (120) as shown in FIGS. 1 and 2, and on the side, an insertion fixing groove (220) is formed in which an insertion bundle (350) of an auxiliary support is inserted and fixed as shown in FIG. 4.

[0044] The above-mentioned support (200) is connected and fixed to the top of the school building, and in order to firmly support and fix the support (400) that fixes the support (200) upright is fixed between the support supports (200). The support supports (400) can be fixed in multiple numbers and can be manufactured in various shapes, but they can be said to have the same purpose of supporting and fixing the support (200).

[0045] In addition, as shown in FIGS. 5 to 7, an evacuation means (210) may be formed on each side of the main support (200), and the evacuation means (210) may be composed of any one selected from among stairs (211) that function as a handrail and a footrest, a vertical bar (212) extending to the ground, or a rope (213) with knots formed at regular intervals. In order to prevent falling during the descent, a ladder may be placed and an existing ladder may be used, or a safety fence (not shown) may be installed in the outer direction of the evacuation means, thereby enabling safer evacuation from concrete buildings such as government offices and townhouses.

[0046] As shown in FIG. 3, the above auxiliary support (300) is provided with a fixing end (310) so that it can be inserted into each floor corner where the pillar (10) and the vertical beam (20) and the horizontal beam (30) of the school building intersect and support the bottom surface of the vertical beam (20).

[0047] At one end of the above-mentioned anchoring portion (310), a vertical block (320) is fixed to guide the position of the shielding plate (340) to be positioned on the bottom surface of the slab layer (40), and at the same time, a fixing block (330) to which the shielding plate (340) is mounted and fixed is fixed to the upper end of the vertical block (320), and a shielding plate (340) formed in a shape selected from among a circular or polygonal shape to block the falling of collapsed objects is fixed in a detachable manner to the upper end of the fixing block (330).

[0048] In addition, on one side of the mounting end (310) of the auxiliary support, as shown in FIGS. 3 and 4, an insertion unit (350) is fixed so that the auxiliary support (300) can be inserted into the insertion fixing groove (220) of the main support (200) to allow the auxiliary support (300) to be detachably fixed, and at the same time, one or more fastening grooves (221, 351) are formed so that the main support (200) and the bolt (410) and nut (420) can be fixedly coupled.

[0049] A through hole (361) is formed on one side of the mounting end (310) of the auxiliary support (300) through which a connecting fixing rod (360) passes, and the connecting fixing rod (360) is inserted and fixed into the through hole (361) so that the auxiliary support (300) can be connected and fixed inside the school building, thereby providing greater stability.

[0050] These auxiliary supports (300) are inserted in a form that supports the vertical beam (20) while the left and right pairs enter the interior of the building centered on the pillar, like the forks of a forklift, so that they can play a part in preventing the collapse of the building in the event of an earthquake. In addition, since the location where the shielding plate (340) is installed is inside the ceiling of the classroom, it becomes invisible after installation, providing a clean appearance.

[0051] In particular, the shielding plate (340) performs an umbrella-like function to provide a temporary or emergency shelter, thereby preventing casualties caused by falling objects in advance.

[0052] Meanwhile, the above-mentioned base (100) is fixed by being buried inside the ground surface as shown in FIG. 8, and the joint fixing part (120) protrudes from the ground to connect the main support (200) and securely fix it to the auxiliary support.

[0053] When a stronger burial fixation is required, as shown in Fig. 5, one or more rebar bundles (500) are installed on one side of the base plate (110), and then concrete is poured and buried or soil is used to bury the rebar bundles, thereby improving the cohesiveness.

[0054] The rescue structure (S) of the present invention as described above is constructed through independent foundation work separate from the school building, and can be installed on the outer wall of each classroom, and at the same time, auxiliary supports (300) are installed on each floor of the classroom to reinforce earthquake resistance and enable quick and safe evacuation in the event of an emergency earthquake such as an earthquake or fire.

[0055] Although embodiments of the present invention have been described, those skilled in the art will be able to modify and change the present invention in various ways by adding, changing, deleting, or adding components within the scope that does not depart from the spirit of the present invention described in the claims, and this will also be considered to be included within the scope of the rights of the present invention.
