Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction method for constructing an expansion joint so as to close a gap between skeletons of adjacent buildings and to absorb fluctuations of the building. The present invention relates to a construction method for an entering corner portion of an expansion joint when the construction is performed so as to close a frame gap of an adjacent building in which a ridge is formed.

[0002]

2. Description of the Related Art An expansion joint (hereinafter simply referred to as "joint") is constructed so as to close a skeleton gap between adjacent buildings to prevent rainwater from entering and to absorb fluctuations in the buildings. The various construction methods are already known. Conventionally, when a joint is used to close an adjacent skeleton gap in which a corner portion is formed in one skeleton portion, the following construction method has been adopted.
That is, a building 10 in which a parapet 102 is provided around a roof 101 as shown in FIG.
4 and the building 106 whose outer wall surface 105 is higher than the roof 101 are adjacent to each other with a gap V,

A cutout 107 is formed on the outer wall surface 105 of the building 106.
Is formed, and one end portion of the horizontal cover material 109 of the joint 108 is held in the notch 107, the horizontal cover material 1
At 09, the lateral skeleton gap is closed, and at the same time, a portion of the outer surface of the tower 103 where the horizontal cover material 109 abuts is cut out to insert the end portion of the horizontal cover material 109, and the caulking process 110 is performed. Side cover material 109 to Toya 10
It was stuck to 3. In this way, the horizontal cover material 109 closes the horizontal frame gap, and the corner cover material 111 is arranged above the horizontal cover material 109 so as to close the vertical frame gap, and the lower end thereof is the upper surface of the horizontal cover material 109. The joint 112 was constructed by abutting against the above and closing it with a caulking material, etc. to close the longitudinal body gap.

Further, FIG. 11 shows a building 113 and a building 114 of the same height. Parapets 117 and 118 are provided around roofs 115 and 116, respectively, and tower houses 119 and 12 are provided.
0 is set up. In this case, the lateral cover material 121 is straddled over the parapets 117 and 118, and at the same time, a notch is formed on the outer surface of the towers 119 and 120 with which the lateral cover material 121 abuts, and one end of the lateral cover material 121 is inserted. Then, the horizontal cover material 121 is fixed to the towers 119 and 120 by caulking 122, and the vertical cover material 12 is attached to the rising portions of the towers 119 and 120.
3 (illustrated by an imaginary line) was installed to close the longitudinal body gap.

[0005]

Originally, by constructing the joint in this way, it should be possible to surely absorb the fluctuation of the building and prevent rainwater from entering the body gap. Regardless, as mentioned above, if one end of the horizontal cover material comes into contact with the outer surface of the tower or the like, insert one end of the horizontal cover material into the notch formed in a part of this outer surface for waterproofing and caulking treatment. There is a problem in that the joint does not function sufficiently because it has to be fixed by fixing.

That is, as shown in FIG. 11, both buildings 11
When a variation in the xx direction occurs between the 3 and 114 frames,
Since one end of the horizontal cover material 121 is fixed to the tower houses 119 and 120, the variation cannot be absorbed, and if the variation in the yy direction occurs, the horizontal cover material 121 itself is damaged. In any case, there was a problem that it did not function sufficiently.

Furthermore, since the lower end portion of the vertical cover member 123 is only in contact with the upper surface of the horizontal cover member 121, rainwater intrudes through the gap between the cover members,
In this case, it is possible to form a rising portion with a slight height at one end portion of the horizontal cover material 121 located inside the vertical cover material 123 to prevent rainwater from entering. Since it cannot be set too high, it was not possible to obtain a sufficient waterproof effect.

Therefore, as shown in FIGS. 12 and 13, a draining member 124 is interposed between the horizontal cover member 121 and the vertical cover member 123, and between the draining member 124 and the horizontal cover member 121. A method of performing the caulking process 125 and the caulking process 126 on the vertical cover material 123 and the draining member 124 has been adopted. However, in this case, since the draining member 124 is fixed to the tower houses 119 and 120, as a result, the lateral cover material 121 cannot absorb the fluctuation of the building.

As described above, since the joint constructed in the frame gap of the adjoining building in which the corner is formed by the above-mentioned conventional construction method cannot exhibit sufficient followability to the fluctuation of the building, There is a serious problem that it is not possible to absorb the fluctuation of the building, and the waterproof effect of the body gap is easily impaired.

The present invention has been made to solve various problems caused by such a conventional construction method, and an object of the present invention is to provide a joint with an adjoining corner portion having the above-described entry corner portion. Even if it is installed in the structure gap of a building, it is possible to sufficiently perform the basic functions of the joint, that is, the function of absorbing the fluctuation of the building and the waterproof function of preventing rainwater from entering the structure gap. It is intended to provide a construction method for a corner portion.

[0011]

In order to solve the above-mentioned problems, according to the present invention, a frame gap of an adjacent skeleton in which a corner portion is formed in one or both of the skeleton portions is defined by vertical and horizontal crossing directions at the corner portion. In the case of constructing a joint that is to be closed, the horizontal cover material that closes the lateral frame gap is placed across both adjacent skeletons, while A vertical overhanging wall that straddles the cover material in its width direction is formed, and a vertical opening is formed between the tip end side of this overhanging wall and the other side of the body, and the vertical opening is extended over this vertical opening. The present invention is characterized by a joint corner installation method in which a vertical cover member is movably supported on the tip end side of the outlet wall and on the other side of the body.

Further, in the case where the inner corner portion is formed in one of the body parts, a lateral cover material for closing the lateral body gap is fixed to the body side having no inner corner portion, and the lateral cover material is also provided. Is applied to the top end on the side of the body with the inside corners, while forming a vertically extending wall that spans the width of the horizontal cover material from the side of the body to which the horizontal cover material is fixed, and A space between the lower end of the wall and the horizontal cover material is sealed, and a vertical opening having an opening width in the longitudinal direction of the horizontal cover material is formed between this tip of the overhanging wall and the other side of the body. It is possible to provide a construction method for a corner portion of a joint in which a vertical cover member that is movably supported on the tip end side of the overhanging wall and the other side of the body is disposed in the opening of the joint.

Further, when the inner corner portions are formed in both the skeleton portions, a horizontal cover material for closing the skeleton gap in the lateral direction is arranged so as to straddle both adjacent skeleton bodies, while the horizontal cover material is provided in the longitudinal direction. After forming a sleeve wall from one side of the body that sandwiches the body gap, form a vertical extension wall that spans the horizontal cover material in the width direction from this sleeve wall, and at least the lower end of the extension wall and the horizontal side. The cover materials are hermetically sealed, and a vertical opening having an opening width in the longitudinal direction of the horizontal cover material is formed between the tip end side of the overhanging wall and the other side of the body. A construction method for a corner portion of a joint in which a vertical cover member movably supported on the tip end side of the overhanging wall and the other body side can be provided.

[0014]

The bulging wall and the sleeve wall protruding from one of the skeletons are integral with the skeleton, and both follow the movement of the skeleton. Therefore, the vertical cover material constructed to close the vertical opening formed between the overhanging wall and the other side of the body reliably absorbs the fluctuation between the one side of the body and the other side of the body. can do. Moreover, since the lower end of the overhanging wall or sleeve wall and the lateral cover member are sealed, it is possible to reliably waterproof the body gap.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the method for applying a corner of a joint according to the present invention is used will be described below with reference to the drawings.

1 to 3 show the construction method of the present invention.
It is an example of a state in which a joint is constructed so as to close the body gap in which the corner portion is formed. That is, in FIGS. 1 to 3, while the parapet 2 is provided around the rooftop 1,
When a building 4 with a tower 3 and a building 6 whose outer wall surface 5 is higher than the roof 1 are adjacent to each other with a lateral gap A, the building space between the two buildings 4, 6 is It shows the state in which the joint 8 and the like have been installed so as to close the vertical crosswise direction.

The joint 8 extends from the outer wall surface 5 of the building 6 in a lateral direction to a projecting wall 9 that reaches the top end portion of the parapet 2, and similarly from the outer wall surface 7 of the tower building 3. It is variably constructed so as to close the longitudinal opening formed between the projecting wall 10 and the projecting wall 10, and can be constructed in various configurations. What is shown in FIGS. 2 and 5 as an example will be described later.

The overhanging wall 9 fixes the C-shaped steel material 11 to the outer wall surface 5 of the building 6, and subsequently fixes the steel base material 12 to the outer end surface of the steel material 11 so as to project from the outer wall surface 5. A C-shaped steel material 13 is fixed to the outer end surface of the base material 12, and an aluminum panel 14 formed by appropriately bending an aluminum plate is fixed so as to cover the entire outer surface of the C-shaped steel material 13 so as to project as a wall. Further, when the projecting wall 9 is provided, as shown in FIG. 4, there is provided a gap a between the upper surface of the parapet 2 and a lateral cover material 19 which will be described later. Note that the overhang wall 9 may be made of reinforced concrete integrally with the outer wall surface 5 instead of the steel material 11 or the like as described above.

The overhanging wall 10 fixes the C-shaped steel material 15 to the outer wall surface 7, and subsequently fixes the steel base material 16 to the outer end surface of the steel material 15 so as to project from the outer wall surface 7.
Further, a C-shaped steel material 17 is fixed to the outer end surface of the base material 16, and an aluminum panel 18 in which an aluminum plate is bent into an L shape so as to cover the entire outer surface is fixed thereon, so that a protrusion like the overhanging wall 9 is formed. Like the overhanging wall 9, a gap a is provided between the parapet 2 and the upper surface of the parapet 2. Of course, it may be made of reinforced concrete that is integrated with the outer wall surface 7.

The gap a is provided for constructing the joint 20 composed of the lateral cover material 19 and the like.
The joint 20 has an arbitrary configuration that can block fluctuations of the building 4 or 6 so as to be able to absorb the fluctuation, and one end of the joint 20 is held by a receiving member fixed to a notch 21 formed in a part of the outer wall surface 5. The lateral cover member 19 is fixed to the outer wall surface 5 and is attached to the top end of the parapet 2 so as to be slidable. It was constructed to close the. Also,
In order to seal the gap between the lower end of the overhanging wall 9 and the horizontal cover member 19, the horizontal cover member 19 is inserted at least up to the lower end of the aluminum panel 14.

In addition, a caulking process 22 is performed in the gap between the lower end of the overhanging wall 9 and the lateral cover material 19 in order to seal it, but a caulking process 23 is also performed in the gap between the notch 21 and the receiving member. And sealed. Since both the overhanging wall 9 and the lateral cover member 19 are fixed to the outer wall surface 5 in this manner, both of them move together with the building 6, and similarly, the overhanging wall 10 includes the building 4 and the building 4. It will move together with.

The joint 8 can be constructed in various configurations as described above, one example of which is shown in FIGS.
It is shown in. That is, the joint 8 has a long flat plate-shaped vertical cover member 24 formed at both ends of the flat plate member 24a with bent portions 24b which can come into contact with the flat plate member 30a of the vertical cover member 30 described below from the back side, and a cross section of the joint. Have a letter or Z shape,

5, a hook metal fitting 26 having an L-shaped cross section, which can be hooked and fixed to
Shaft mounting part 2 having a bolt insertion hole for shaft mounting to the latching metal 26
7a is formed at one end of a flat plate, and a shaft mounting metal fitting 27 fixed to the upper surface of a receiving metal fitting 29 described later and a long flat plate are appropriately bent in the lateral direction, and fixed to a vertical cover material 30 described below from the back side. At the same time, an S-shaped metal fitting 28 provided with a pivoting convex portion 28a that can be pivotally attached to a receiving metal fitting 29, which will be described later, and a pivotal attachment concave portion 29a that can pivotally attach the pivotal attachment convex portion 28a are formed on the upper surface of the long flat plate. A water blocking sheet fastening part 29b is formed at one end of the aluminum panel 14
Alternatively, a bracket 29 that is fixed to 18 from above and a bent portion 30b that appropriately bends a long flat plate and contacts the flat plate portion 24a of the vertical cover member 24 from the front side are formed at one end of the flat plate portion 30a. The vertical cover member 30 having the spring body 30c fixed to the other end is the main constituent element.

The construction after construction will be described in detail. In the joint 8, the metal fittings 29, 29 are attached to the water blocking sheet fastening portion 29b.
To the aluminum panel 14 or 18 such that they face each other, and the shaft fittings 27a are projected on the respective upper sides to fix the metal fittings 27 and 27 with screws. The pivotal protrusion 28a of the metal fitting 28,
28a is pivotally fitted into the fitting recesses 29a, 29a of the receiving fittings 29, 29,

Next, the support member 25 is attached to the vertical cover member 2 from the back side.
4 and further, hooking metal fittings 26, 26 are hooked and fixed to the support member 25, and the metal fittings 26, 26 are screwed to the shaft fitting portions 27a, 27a from the outside of the metal fittings 26, 26. The shaft fittings 27, 27 and the spring body 30.
bending portions 30b and 30 so that c and 30c are arranged at both ends.
b is brought into contact with the flat plate portion 24a from the front side of the vertical cover member 24, and the bent portions 24b, 24b of the vertical cover member 24 are brought into contact with the flat plate portion 30a from the back side of the vertical cover member 30 to install the cover member 30, From the outside, fix the vertical cover member 30 to the S-shaped metal fittings 28, 28 with screws,

Further, the vertical cover member 30 and the aluminum panel 1
The caulking process 31 is performed in the gap between the vertical cover member 30 and the outer wall surface 7, and the caulking process 32 is performed in the gap between the vertical cover member 30 and the outer wall surface 7.

In this joint 8, a shaft fitting metal fitting 27 is screwed to the hook fitting metal fitting 26 so as to be axially mounted, and an S-shaped metal fitting 28 and a receiving metal fitting 29 are pivotally fitted to each other. Vertical cover material 2 that absorbs fluctuations in the XX direction of FIG.
4 and the vertical cover members 30 and 30 have their bent portions abutting each other, so that the fluctuations in the YY direction are absorbed and
Variations in the Z-Z direction can also be absorbed.

In this way, the joint 8 is attached to the overhanging wall 9
By constructing so as to close the vertical opening formed by the projecting wall 10 and the projecting wall 10, the projecting wall 9 integrally follows the movement of the building 6 and the projecting wall 10 becomes the building 4. Since the joint 8 integrally follows the movement, the joint 8 can absorb the variation between the two overhanging walls 9 and 10, that is, the variation of both the buildings 4 and 6. Further, the joint 20 closes the lateral body gap and exhibits its original movable performance, can follow the vertical movement of the building 6 and the parapet 2, and can absorb the fluctuation of both.

Moreover, since the joints 8 and 20 and the overhanging walls 9 and 10 are waterproofed by sealing the gaps by caulking treatments 22, 23, 31 and 32, the gaps between the skeletons of both buildings 4 and 6 are covered with water. There is no danger of invading.
It should be noted that the order of construction of the joint 8, the joint 20, and the overhanging walls 9 and 10 in the above construction method does not matter, and which one is constructed first is arbitrary. Further, in order to seal the gap, packing can be inserted and sealed instead of caulking.

When constructing the joint 8 as described above, the projecting wall 10 was projected from the outer wall surface 7 of the tower 3. However, the projecting wall 10 was not projecting and the joint 33 shown in FIG. 6 was constructed. You can also do it. In this joint 33, an L-shaped corner cover member 34 is installed via a spring body 35 so as to close the vertical opening appearing between the outer surface of the overhanging wall 9 and the outer wall surface 7. Therefore, the fluctuation between the buildings 4 and 6 can be reliably absorbed by the action of the spring body 35.

Also in this case, as in the case where the joint 8 is installed, a joint 20 (not shown) is installed on the lower side of the overhanging wall 9 in order to close the lateral frame gap by the horizontal cover member 19. In addition, the overhanging wall 9 and the horizontal cover material 1
Since the space between 9 and 9 is sealed, the gap between both buildings can be surely waterproofed.

On the other hand, FIG. 7 shows a building 36 and a building 37 of the same height, in which parapets 40 and 41 are provided around roofs 38 and 39, respectively, and tower roofs 42 and 43 are erected. , A joint 4 having the same structure as the joint 8 in order to close the body gap between the two buildings 36, 37.
4 is a diagram showing a state in which 4 and the like are constructed.

Explaining in detail, the building 36 or the building 3
There is a gap between one of the outer wall surfaces of 7 (the outer wall surface 45 of the building 37 is shown) between the parapets 40 and 41 so that a joint 47 composed of a lateral cover member 46 described later can be inserted. The sleeve wall 48 and the sleeve wall 4
An overhanging wall 49 is laterally projected from the outer side surface of the tip of 8, and the outer wall surface of the other building (the one shown is the building 3
6, an overhanging wall 51 such as the overhanging wall 49 is protruded from the outer wall surface 50) of 6.

Then, in order to close the vertical opening formed between the overhanging wall 49 and the overhanging wall 51, the joint 4 is closed.
4 and further, in order to close the lateral body gap in the gap between the sleeve wall 48 and the overhanging wall 49 and the parapets 40 and 41, the lateral cover member 46 is joined across the parapets 40 and 41. 47 construction,

Further, a caulking process 52 is performed to seal the gap between the lateral cover member 46 and the sleeve wall 48 and the overhanging wall 49, and a caulking process 53 is performed on the gap between the joint 44 and the overhanging wall 49. In addition, the gap between the joint 44 and the overhang wall 51 is shown by caulking 54.

The sleeve wall 48 is a reinforced concrete wall projecting from the outer wall surface 45, and the projecting wall 49 is laterally projected from the outer surface of the tip end of the sleeve wall 48 by a C-shaped steel material or the like like the projecting wall 9. The wall is provided, and the sleeve wall 48 and the overhanging wall 49 form an L shape as a whole. Also, the overhang wall 51
Like the overhanging wall 49, is a wall protruding from the outer wall surface 50 by a C-type steel material or the like. Each of the sleeve wall 48 and the overhanging walls 49, 51 may be a wall protruding from a C-type steel material or the like, or the sleeve wall 48 and the overhanging wall 49 may be integrally formed by reinforced concrete, Of course, the overhang wall 51 may be made of reinforced concrete.

As shown in FIG. 8, the joint 47 has a base body 55, which is formed by appropriately bending a C-shaped steel material at its central portion, through which bolts 56 and 57 are inserted so that the vertical movement of the parapets 40 and 41 can be absorbed. Then, the horizontal cover member 46 is coated from the outside of the base body 55 to be applied. As shown in FIG. 9, bolt insertion holes 55a and 55b are provided in the bottom surface portion of the base body 55, and 55a on the side of the building 36 where the sleeve wall 48 does not project is a long hole.
On the other hand, 55b is a normal bolt insertion hole.
Therefore, the joint 47 is fixed to the parapet 41 and is free to the parapet 40 at the same time, and as a result, the joint 47 and the building 37 follow the movement.

Thus, the joints 4 are attached to the buildings 36 and 37.
Even when 4, 47 are constructed, the joint 44 closes the vertical opening between the buildings 36, 37 by closing the vertical opening that appears due to the protruding wall 49 and the protruding wall 51. It is possible to close the frame gap and surely absorb the fluctuations of both buildings 36 and 37. Besides, it is also possible to construct a joint such as the joint 33 on the overhanging wall 49 and the outer wall surface 50 without projecting the overhanging wall 51, and securely close the longitudinal body gap. .

Further, since the gap between the lateral cover member 46 straddling the parapets 40 and 41 and the sleeve wall 48 and the overhanging wall 49 is sealed to close the lateral body gap, the body gap is also waterproofed. In addition to being good, the joint 47 can reliably absorb the fluctuation between the buildings 36 and 37.

[0039]

According to the construction method of the present invention, with respect to the overhanging wall in which the vertical cover material projects from one building, and the overhanging wall or the outside surface projecting from the outer surface of the other tower or the like. Since it is constructed so as to cover the vertical body gap, the joint consisting of vertical cover materials etc. can exert sufficient movable performance, can reliably absorb the fluctuation of both buildings, and the horizontal cover material Since the construction is performed so as to close the lateral body gap, and the lateral cover material and the overhanging wall or the sleeve wall are hermetically sealed, the body gap can be reliably waterproofed.
