Description

Precast vertical core module using lattice structure and method of constructing vertical core structure using the same

The present invention relates to a precast vertical core module using a lattice structure. More specifically, a precast vertical core module using a lattice-type structure capable of rapidly assembling and constructing a vertical core structure for a building structure, which can reduce its own weight and secure rigidity in two directions, enabling stable layered construction, and this It relates to a method of constructing a vertical core structure using

1a is a construction example of a vertical core structure in which a conventional elevator is installed therein.

That is, the elevator installed inside the building structure, such as a high-rise building, is first constructed by installing it inside the vertical core structure 31, which is installed first along with the stairs, and the beam around the vertical core structure 31 as a standard. The member 32 is connected to construct the building structure by constructing the floor plate and the frame structure.

This vertical core structure 31 is constructed continuously upwards by concrete pouring and curing one layer at a time using a system formwork, and since this is a wet concrete pouring method in which concrete is poured and cured at the site, the beam member 32 is A method of exposing a buried connection member 33 such as a connectable coupler, insert, or connecting reinforcing bar on an outer circumferential surface and connecting the beam member 32 to the buried connection member 33 from the outside is used.

However, when the vertical core structure 31 is constructed by pouring concrete using a system formwork, workability and workability deteriorate, and there is a limit that it takes too long to cure.

1b and 1c show construction examples of a vertical core structure (A) for a rooftop structure that is conventionally assembled and installed horizontally.

That is, as shown in FIG. 1B, it is lifted and brought in by the working crane 30 that is dismantled after being fixedly installed, and it can be seen that the L-shaped precast wall module 10 is used.

In this L-shaped precast wall module 10, a vertical hollow part 11 is formed to reduce its own weight, and it is assembled and installed on the floor plate horizontally to form the outer wall of the vertical core structure A in the form of a rectangular parallelepiped. Able to know.

In addition, referring to FIG. 1C, it can be seen that the precast inner wall portion 13 is also installed in a precast manner in order to form a partitioned inner space by being installed on the inner surface of the vertical core structure (A).

It can be seen that the precast inner wall portion 13 and the L-shaped precast wall module 10 use a connecting member 15 such as a U-shaped channel member, for example.

At this time, it is inserted into the vertical hollow part 11 of the L-shaped precast wall module 10 and fastened to the lower fixture 21 formed so that the lower end is exposed in advance to the floor plate, and the upper end is L-shaped precast wall module ( It can be seen that the vertical connection device 20 fixed on the upper surface of 10) is further installed to facilitate stable top-down stacking construction.

That is, although it has been previously introduced that the vertical core structure (A) can be laminated in an open space using a precast method, that is, a precast wall module, the stacking height of the vertical core structure (A) is higher than that of the rooftop structure. In the case of a relatively small case, there is no big problem, but in the case of a vertical core structure (A) for a high-rise building structure, the cross section of the precast wall module has to be large because the weight of the vertical core structure (A) continues to accumulate at the bottom, resulting in lifting and Due to mounting problems, the use of precast wall modules was limited.

2a and 2b are examples of a precast vertical core module 100 using the lattice structure 150 of the present invention, FIG. 2c is an example of the lattice structure 150 of the present invention, FIGS. 3a and 3b are An exemplary view of the connection of the precast vertical core module 100 using the lattice structure 150 of the present invention and an exemplary view of the vertical core structure A are shown.

As shown in FIGS. 2A and 2B, the precast vertical core module 100 using the lattice structure 150 has a lattice structure 150 buried therein to secure 2-way rigidity, and FIGS. 3A and 2B. As shown in 3b, the L- or C-shaped precast core modules 110 and 120 are lifted by the working crane and stably assembled using the transverse connecting means 140 and the lattice structure 150 in the transverse direction And the vertical core structure (A) is constructed by stacking construction while connecting up and down.

That is, since the lattice structure 150 also serves to connect the top and bottom of the L-shaped or U-shaped precast core modules 110 and 120, simple stacking construction is possible, and by using the horizontal connecting means 140 The L-shaped or U-shaped precast core modules 110 and 120 can be constructed by simply connecting them in the transverse direction to each other.

Accordingly, the precast vertical core module 100 using the lattice structure of the present invention includes a L-shaped precast core module 110, a U-shaped precast core module 120, and a horizontal connecting means as shown in FIGS. 2A and 2B. (140) and a lattice structure (150).

First, in the L-shaped precast core module 110, as shown in FIGS. 2A and 3A, the vertical core structure (A) in the form of a hollow wall installed to accommodate the elevator inside the building structure is laminated on the floor plate (B) It is a precast concrete wall for assembling and constructing in a modular fashion. At this time, the meaning of the module is the meaning of a unit member that is manufactured in the same form by a precast method, transported to the site, lifted, and then connected in the vertical and horizontal directions for assembly and construction.

In this way, when the L-shaped precast core module 110 is used, referring to FIG. 3A, since the cross-section is manufactured in the L-shape, simply assembling and connecting a plurality of them with the same size and shape to each other, The outer wall of the vertical core structure (A) can be assembled and constructed by horizontal assembly, and since it can stand on its own, there is an advantage that no fall prevention means is required.

In addition, when the L-shaped precast core module 110 is used, it is possible to construct a more economical vertical core structure (A) while lifting it using a separate working crane and performing layered construction.

As shown in FIGS. 2A and 3A, the L-shaped precast core module 110 is a wall made of a L-shaped reinforced concrete body 111, which is assembled by horizontally connecting a plurality of them in the horizontal direction and stacked up and down It is constructed as the outer wall of the vertical core structure (A).

Inside the L-shaped precast core module 110, reinforcing bar assemblies (not shown) are set near both surfaces of the L-shaped precast core module 110 to ensure a covering thickness.

Accordingly, referring to FIG. 2A between the two reinforcing bar assemblies, a lattice structure 150 is set so that the hollow part S1 is naturally formed by the lattice structure 150. The L-shaped precast core module 110 ), it can be seen that the hollow part (S1) is filled with wall concrete because the L-shaped precast core modules 110 located at the bottom receive a large load due to their own weight, The positioned L-shaped precast core modules 110 may be finished by inserting hollow blocks such as EPS blocks into the hollow parts S1 to play a role of reducing their own weight.

Although this N-shaped precast core module 110 is not shown, the lifted reinforcing bar assembly and the lattice structure 150 are lowered and inserted into the vertical mold method in a state where a plurality of vertical mold type steel formworks are installed adjacent to each other. After setting to

Concrete is poured into the steel formwork, and after demolding, it is lifted to embed the reinforced concrete body 111 inside the reinforced concrete body 111, and many of them are stacked vertically in the vertical direction. It is also mounted in the vertical direction and brought to the site, and is also lifted in the vertical direction as it is for laminated construction.

At this time, referring to FIG. 2A, both ends of the reinforced concrete body 111 are formed with both connection flanges 112 spaced apart from each other to form an end connection space S2, and extending from the lattice structure 150. It can be seen that the transverse connection means 140 extends to the outside via the end connection space S2 and is exposed.

Next, the U-shaped precast core module 120, as shown in FIGS. 2B and 3B, is formed in a U-shape in contrast to the L-shaped precast core module 110, and the C-shaped reinforced concrete body At both ends of the portion 121, connection flanges 122 spaced apart from each other to form an end connection space S2 are formed, and the transverse connection means 140 extending from the lattice structure 150 are connected to the end connection space ( It is the same as extending and exposing to the outside via S2).

When the U-shaped precast core module 120 is used, compared to the use of the L-shaped precast core module 110, the overall cross-sectional size increases the self-weight somewhat, but with a smaller number of single-stage vertical core structures ( A) Construction becomes possible.

That is, when the U-shaped precast core module 120 is used, referring to FIG. 3B, since the cross-section is manufactured in a U-shape, simply assembling and connecting two of the same size and shape to each other, The outer wall of the vertical core structure (A) can be assembled and constructed by horizontal assembly, and it is also self-supporting, so there is an advantage that no fall prevention means is required.

In addition, when the U-shaped precast core module 120 is used, it is possible to carry out stacking construction while lifting using a separate working crane, which is relatively fast and economical compared to the L-shaped precast core module 110. Vertical core Construction of the structure (A) becomes possible.

Referring to FIG. 2B, the U-shaped precast core module 120 is a wall structure made of a reinforced concrete body 121, and is constructed as a wall of the vertical core structure A.

Inside the C-shaped precast core module 120, it is also preferable to set a reinforcing bar assembly (not shown) to secure a coating thickness near both surfaces of the C-shaped precast core module 120.

Accordingly, referring to FIG. 2B, between the two reinforcing bar assemblies, a lattice structure 150 is also set, so that the hollow part S1 is naturally formed by the lattice structure 150. : 121, 122, 123), since the C-shaped precast core modules 120 located at the bottom receive a large load due to their own weight, the hollow part (S1) is filled with wall concrete. It is the same, It is the same that the hollow part (S1) can be finished by inserting a hollow block such as an EPS block so that the upper U-shaped precast core modules 120 play a role of reducing their own weight.

Next, the horizontal connecting means 140 is equally applied to both the L-shaped precast core module 110 and the U-shaped precast core module 120, as shown in FIGS. 3A and 3B.

First, the transverse connecting means 140 installed at the end of the L-shaped precast core module 110 as shown in FIG. 3A will be described as follows.

As described above, at both ends of the reinforced concrete body 111, both connection flanges 112 are spaced apart from each other to form an end connection space S2, and the lattice structure 150 extends from the transverse connection The means 140 is extended to the outside via the end connection space (S2) to be exposed.

Accordingly, the transverse connecting means 140 includes a horizontal cross connector 141 and an end anchoring plate 142, as shown in FIG. 3A.

First, in the horizontal cross connector 141, as shown in FIG. 3A, both connection flanges 112 of the L-shaped precast core module 110 connected in the transverse direction are in contact with each other, and the end connection space S2 is horizontal to each other It can be seen that they communicate, and it can be seen that the horizontal cross connectors 141 are arranged to cross each other in the connected end connection space S2.

The horizontal cross connector 141 installed crosswise in this way can be formed by using reinforcing bars, bar members, etc., and in particular, one side is connected to the outer circumferential surface of the lattice structure 150 by welding, etc., and the other side extends into the connected end connection space S2. It can be seen that it is formed so that

As shown in FIG. 3A, the end anchoring plate 142 is formed to be orthogonal to the end of the horizontal cross-connecting member 141, and the end anchoring plate 142 faces each other at both ends of the horizontal cross-connecting member 141 crossing each other. As you can see, it is possible to effectively resist the tensile force that causes the L-shaped precast core modules 110 to separate from each other and spread.

In this way, the end anchoring plate 142 formed to be orthogonal to the end of the horizontal cross connector 141 is simply formed by a fastening nut fastened to the end of the horizontal cross connector 141 and a fixing plate disposed orthogonally formed on the fastening nut. By increasing the fixing performance of the horizontal cross connector 141, the lateral connection performance of the L-shaped precast core module 110 can be secured even in a small end connection space S2.

In the case of FIG. 3A, one horizontal connecting means 140 is formed to extend from the lattice structure 150 of each L-shaped precast core module 110, but it does not matter if a plurality of them are combined.

Next, as shown in FIG. 3B, the transverse connecting means 140 installed at both ends of the U-shaped precast core module 120 are the same as those installed at both ends of the L-shaped precast core module 110, , Compared to the case of the L-shaped precast core module 110, only the installation location of the transverse connecting means 140 for mutual connection is reduced.

Accordingly, it can be seen that the transverse connecting means 140 includes the horizontal cross connector 141 and the end anchoring plate 142, as shown in FIG. 3B.

First, in the horizontal cross connector 141, as shown in FIG. 3B, both connection flanges 122 of the U-shaped precast core module 120 connected in the transverse direction are in contact with each other, and the end connection space S2 is horizontal to each other It can be seen that they communicate, and it is the same that the horizontal cross connectors 141 are arranged to cross each other in the connected end connection space S2.

The horizontal cross connector 141 installed crosswise in this way can also be used with reinforcing bars, bar members, etc., and in particular, one side is connected to the outer circumferential surface of each tube constituting the lattice structure 150 by welding, etc., and the other side is connected to the end connection space. Forming to extend to (S2) is the same.

As shown in FIG. 3B, the end anchoring plate 142 is also formed to be orthogonal to the end of the horizontal cross-connecting member 141, and the end anchoring plate 142 faces each other at both ends of the horizontal cross-connecting member 141 crossing each other. As you can see, it is the same that the U-shaped precast core modules 120 can more effectively resist the tensile force that separates them from each other.

In this way, the end anchoring plate 142 formed to be orthogonal to the end of the horizontal cross connector 141 is simply formed by a fastening nut fastened to the end of the horizontal cross connector 141 and a fixing plate disposed orthogonally formed on the fastening nut. The installation is possible, and the horizontal connection performance of the U-shaped precast core module 120 can be secured even in a small end connection space (S2) by increasing the fixing performance of the horizontal cross connector 141. Do.

In the case of FIG. 3B, one transverse connecting means 140 is formed so that one extends from the lattice structure 150 of each U-shaped precast core module 120, but it does not matter if a plurality of them are combined. Do.

Next, the lattice structure 150 can be equally applied to both the L-shaped precast core module 110 and the U-shaped precast core module 120, as shown in FIGS. 2A and 2B. It serves to ensure the bending rigidity that can resist the load that is embedded in the precast core modules (110, 120) of the shape, and connects the top and bottom of the L-shaped or U-shaped precast core modules (110, 120) It will also play a role.

It can be seen that the lattice structure 150 is formed in an L-shape in the case of the L-shaped precast core module 110 and in a C-shape in the case of the C-shaped precast core module 120.

Accordingly, as shown in FIG. 2A, looking at the L-shaped precast core module 110 as a standard, the lattice-like member 151 is installed so as to cross each other on the same plane in the form of a square lattice in the horizontal and vertical directions, It can be seen that the overall shape is also formed in a b-shape.

That is, it extends to the upper and lower surfaces of the reinforced concrete body 111 of the L-shaped precast core module 110, and the vertical member 152 further extends from the bottom of the reinforced concrete body 111 to form an L-shaped free It is used for vertical connection with the cast core module 110.

At this time, when using an H-shaped steel frame member made of steel or a square tube member as the lattice-shaped member 151, since the ready-made product can be used as it is, it is cut to the required length with little processing required, set in a lattice shape, welded, etc. It is possible to manufacture the lattice-like structure 150 by integrating with

In this way, when the lattice structure 150 is used, the effect of increasing the bending stiffness in the lateral and longitudinal directions is greater than the effect of increasing the dead weight of the L-shaped precast core module 110, so the L-shaped precast core module 110 thickness can be minimized.

Accordingly, according to the lattice-shaped member 151, the hollow part S1 is formed naturally, can efficiently correspond to the size of the L-shaped precast core module 110, and is formed to be embedded in the reinforced concrete body 111 will make

This lattice structure 150 is also used as a means for vertical connection of the L-shaped precast core module 110 and connection with the bottom plate B on which the vertical core structure A is installed.

That is, as shown in FIG. 2A, on the upper surface of the lattice member 151, a vertical member 152, which is a square tube member into which the vertical member 152 of the L-shaped precast core module 110 stacked upward is inserted, is formed. become,

The lower surface of the lattice member 151 is connected to the bottom plate B or the L-shaped precast core module 110 located at the bottom using a vertical member 152, which is an H-shaped steel frame member extending downward. do.

Accordingly, referring to FIG. 2A, the vertical member 152 is a square pipe member and extends to the upper surface of the reinforced concrete body 111 to be exposed to the outside for vertical connection of the L-shaped precast core modules 110,

It can be seen that the connecting opening 113 is formed on the upper surface of the reinforced concrete body 111 so that the vertical members 152 of the L-shaped precast core module 110 located at the top can be inserted into each other. .

In addition, referring to FIG. 2A, the vertical member 152 is an H-shaped steel frame member that extends further downward from the bottom surface of the reinforced concrete body 111 for vertical connection of the L-shaped precast core module 110 and is exposed to the outside let it be,

They are made to be inserted into the vertical member 152, which is a square tube member of the L-shaped precast core module 110 located at the bottom.

Also, referring to FIG. 2C (upper side), even if an H-shaped steel frame member is used as the lattice member 151 and vertical members 152, which are square tubular members, are integrally formed on the upper and lower surfaces of the lattice member 151, respectively. In this way, by combining the H-shaped member and the square pipe member, the integrity with the reinforced concrete body 111 can be improved, and since the H-shaped member is also a ready-made product, it is easy to manufacture.

Also, referring to FIG. 2C (lower side), an H-shaped steel frame member is also used as the lattice-like member 151, and square tube members are formed on the upper and lower surfaces as the lattice-like member 151, and the vertical member 152, which is an H-shaped steel frame member It can be seen that is integrally formed.

Accordingly, it can be seen that the lattice structures 150:151 and 152 can be manufactured by combining square tubular members and H-shaped steel frame members.

As shown in FIG. 2B, when looking at the U-shaped precast core module 120 as a standard, it is installed so as to cross each other on the same plane in the form of a square grid in the horizontal and vertical directions using the grid member 151, and the overall It can be seen that the shape is also formed in a U-shape.

That is, it extends to the upper and lower surfaces of the reinforced concrete body 121 of the C-shaped precast core module 120, and the vertical member 152 further extends from the bottom of the reinforced concrete body 121 to form a C-shaped free It is the same to use for vertical connection with the cast core module 120.

At this time, when an H-shaped steel frame member made of steel or the like is used as the lattice member 151, since an off-the-shelf product can be used as it is, it is cut to the required length without much processing, set in a lattice shape, and integrated by welding. It is the same that the lattice structure 150 can be fabricated.

In this way, when the lattice structure 150 is used, the effect of increasing the bending stiffness in the horizontal and vertical directions is greater than the effect of increasing the dead weight of the U-shaped precast core module 120, so the U-shaped precast core module 120 thickness can be minimized.

Accordingly, referring to FIG. 2B, the hollow part S1 is naturally formed in the lattice-shaped member 151, and can efficiently correspond to the size of the U-shaped precast core module 120, and the U-shaped precast core Forming to be embedded in the reinforced concrete body 121 of the module 120 is the same.

Referring to FIG. 2B, this lattice structure 150 is also used as a means for vertical connection of the U-shaped precast core module 120 and connection with the bottom plate (B) on which the vertical core structure (A) is installed Doing is the same.

That is, in the lattice member 151, the hollow part S1 is naturally formed, but the hollow part S1 is filled with wall concrete for load resistance, and a finishing material such as an EPS block is added to the hollow part S1. can be installed with

In addition, a vertical member 152, which is a square tube member of the U-shaped precast core module 120 stacked upward, is inserted into the upper surface of the lattice-shaped member 151 to connect it,

The lower surface of the lattice-shaped member 151 is connected to the bottom plate B or the U-shaped precast core module 120 located at the bottom using a vertical member 152, which is an H-shaped steel frame member extending downward. Becoming is also the same.

Accordingly, referring to FIG. 2B, the vertical member 152, which is a square tube member, is exposed to the outside on the upper surface of the reinforced concrete body 121 for vertical connection of the precast core modules 120, and is located at the top. It is also the same that the opening 123 for connection is formed so that the vertical member 152 of the module 120 can be inserted.

Referring also to FIG. 2C (top), even if an H-shaped steel frame member is used as the lattice member 151 and vertical members 152, each of which are square tubular members, are integrally formed on the upper and lower surfaces of the lattice member 151, respectively. In this way, by combining the H-shaped member and the square pipe member, the integrity with the reinforced concrete body 111 can be improved, and since the H-shaped member is also a ready-made product, it is easy to manufacture.

Also, referring to FIG. 2C (lower side), an H-shaped steel frame member is also used as the lattice-like member 151, and square tube members are formed on the upper and lower surfaces as the lattice-like member 151, and the vertical member 152, which is an H-shaped steel frame member It can be seen that is formed integrally, and thus the lattice structure (150: 151, 152) can be manufactured by combining a square tube member and an H-shaped steel frame member.

At this time, although not shown, the vertical member 152 is inserted into the connection openings 113 and 123 formed on the upper surfaces of the L-shaped or U-shaped precast core modules 110 and 120, and the vertical member 152 is inserted using a filler containing non-shrinkage mortar. The precast vertical core module 100 using the stacked lattice structure can be integrally connected and act.

As a result, the precast vertical core module 100 using the lattice structure of the present invention is a lattice structure 150 in the cross-sectional shape of the vertical core structure A using the L-shaped or U-shaped precast core modules 110 and 120 It is laminated vertically using , but is also connected in the lateral direction using the lateral connecting means 140, and the lattice structure 150 is used to form a b-shaped or c-shaped precast core module (110, 120) By connecting up and down, it can be seen that the vertical core structure (A) can be constructed as shown in FIGS. 3a and 3b.

[Construction method of vertical core structure (A) using precast vertical core module 100 using lattice structure 150 of the present invention]

4A and 4B show examples of a vertical core structure (A) construction method using the precast vertical core module 100 using the lattice structure 150 of the present invention.

In the vertical core structure (A) construction method using the precast vertical core module 100 using the lattice structure 150, the lattice structure 150 is embedded in the reinforced concrete body parts 111 and 121, and the lateral connection surface After manufacturing the precast core modules 110 and 120 in the form of L or U in which the transverse connecting means 140 is formed in advance,

When the elevator of the building structure is constructed, the vertical core structure (A) is constructed by assembling and constructing the vertical core structure (A) by connecting the precast vertical core module 100 to the floor plate (B) in the transverse direction, connecting it up and down and stacking it in multiple stages. Let's take a look at the L-shaped precast core module 110 as a standard.

Accordingly, as shown in FIGS. 4A and 4B, the first to fourth stages of the vertical core structure (A) are constructed by connecting a plurality of L-shaped or U-shaped precast core modules 110 and 120 in the transverse direction and stacking them up and down. Since the cross section of the first floor by the 1st to 4th tiers of the vertical core structure (A) is approximately a rectangular cross section, excluding the entrance, etc.

The precast core modules (110, 120) in the shape of L or U are simply assembled and constructed in one stage horizontally using the horizontal connecting means (140),

The two-stage L- or U-shaped precast core modules 110 and 120 are connected to each other using the vertical member 152 constituting the lattice structure 150 of the L- or U-shaped precast core modules 110 and 120 of the first stage. It can be seen that they are stacked in a way of connecting up and down (insertion connection between vertical members).

At this time, the precast core modules 110 and 120 in the shape of an L or U in the upper surface of the bottom plate (B) and the first stage are inserted into the insertion hole (not shown) formed in the bottom plate (B) by the vertical member 152. Installed you can do it,

The outer wall of the vertical core structure (A) is constructed by connecting the one-stage L- or U-shaped precast core modules 110 and 120 horizontally in the transverse direction, and the two-stage L- or U-shaped precast core modules 110 and 120 The outer wall is extended upwards.

Therefore, four or more stages are constructed in the same way to construct the vertical core structure (A) of the first floor, and the beam member 200 is further connected horizontally to the outer circumferential surface of the vertical core structure (A) of the first floor, as shown in FIG. 4a. This beam member 200 is to be such that the H-shaped steel frame can be used and is connected to the vertical core structure (A) as a frame structure of the building structure to be integrated.

Accordingly, in the case of FIG. 4A, one end of the beam member 200 extends from the lattice member 151 constituting the lattice structure 150 of the L-shaped or U-shaped precast core modules 110 and 120 and exposes the coupler While connecting using the beam member connector 210 including a fixing bolt, the end closing plate formed on one side of the beam member 200 is connected to the outer circumferential surface of the L-shaped or U-shaped precast core modules 110 and 120 by fixing bolts It can be seen that it is being compressed.

In addition, according to Figure 4b it can be seen that the reinforcing member 300 can be used instead of the beam member 200.

Again, the outer circumferential surface of the vertical core structure (A) on the first floor is further connected to the reinforcing bar member 300 horizontally. This reinforcing bar member 300 is connected to the vertical core structure (A) as a framework structure of the building structure to be integrated It is to do.

Accordingly, even in the case of FIG. 4B, one end of the reinforcing bar member 300 extends from the lattice-like member 151 constituting the lattice-like structure 150 of the L-shaped or U-shaped precast core modules 110 and 120 and is exposed The reinforcing bar member connector 310 including a fixing bolt to the coupler is also used to be connected.

As a result, the vertical core structure (A) of the present invention is used as a building structure by allowing the beam member 200 or the reinforcing member 300 to be formed in multiple stages horizontally on the outer circumferential surface, and the beam member 200 or the reinforcing member 300 ) can be used as an internal frame structure for slab construction.
