Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a handrail-type expansion joint that connects adjacent housings such as a passage corridor so as to absorb fluctuation.
[0002]
[Prior art]
In recent years, buildings such as condominiums have become higher-rise and have a structure in which a plurality of buildings are arranged in parallel or adjacent housings are approached. In such a structure, in consideration of the convenience of the user, it is a common construction to cross the outer corridor, connect the corridors, and install an expansion joint at the connecting portion.
On the other hand, most of the buildings have seismic isolation structure, and the upper floors have greater horizontal vibration. For this reason, the gap between the casings becomes wider as the connection part of the upper layer part, the expansion joint is required to have a large movable amount, and a structure with high strength against external pressure including wind pressure is required in terms of strength. Become.
[0003]
The floor of the expansion joint is made by passing a metal plate such as stainless steel to both housings, locking one side to one housing floor end, and allowing the other side to slide relative to the other housing floor end. A structure for mounting is generally adopted.
On the other hand, the connection in the wall portion is not necessarily a satisfactory structure, but a known configuration is exemplified as follows.
[0004]
A panel-shaped wall is used as an expansion joint, and a hollow wall-shaped fixed cover with open ends is installed at the ends of both housings using rotatable hinges. The small joint wall is configured to be slidably inserted into the large joint wall, or a fixed cover is installed on both sides of the housing via hinges in the same manner as described above. A configuration is shown in which a movable cover is interposed between the movable covers, and both sides of the movable cover are slidably inserted into both fixed covers. According to these configurations, the change in the angle of the movable cover with respect to the case caused by the displacement between the adjacent cases can be absorbed by the hinge, and the change in the fixed cover interval caused by the movement in the direction of the case can be absorbed by the slide change of the inserted cover. However, the fixed cover part for inserting one fixed cover or for inserting the movable cover has a heavy burden due to the increased aggregate and increased wall thickness for strength. Since it is indispensable to put a panel as a decorative cover on both the inside and outside of each cover and the design differs depending on the construction property, it is necessary to design the aggregate etc. There are problems such as high costs.
[0005]
There is also disclosed a configuration in which the large joint wall and the small joint wall are slidably locked by locking a locking tool projecting on one side surface of the large joint wall, but this configuration is also disclosed. In addition to the above problems, there is a problem in production and construction costs, such as the necessity to design the large joint wall and the small joint wall separately.
[0006]
In addition, assuming that the laminated panel side wall is an expansion joint, a plurality of unit panel materials having a fixed width and having a folded structure on one side are sequentially arranged in a plane so that about half are overlapped. The two wall surfaces of this structure are opposed to each other as inner and outer wall surfaces, and a multistage pantograph-like support mechanism is disposed between the inner and outer wall surfaces. A plurality of worn X-shaped housings are arranged in parallel, and the X ends are pivotally connected to each other to form a continuous shape of a deformable rhombus (unit pantograph). The inner and outer wall surfaces are linked to the support mechanism. In order to slide the wall to expand or narrow, the unit panel material of the inner and outer wall surfaces facing the pivot part of each unit pantograph is connected to each other to form a laminated panel side-by-side wall part, The ends of the wall structure mounted with a rotatable hinge adjacent precursor ends are illustrated. According to this configuration, it is possible to absorb the fluctuation in the horizontal direction of the adjacent housing, and there is an advantage that the effective movable amount can be greatly increased with respect to the width of the wall portion, but the structure is very complicated and the number of members is also large. There are many problems such as a heavy load, difficult design changes suitable for the purpose, and high construction costs.
[0007]
In addition, as an expansion joint having a handrail shape, pillars are erected using hinges at the ends of both housings, and the original end of a horizontal fixing pipe is fixed to both pillars. A configuration in which a movable pipe is disposed between both fixed pipes by extending a horizontally fixed pipe and inserting both sides of the movable pipe slidably into the two fixed pipes is shown. According to this configuration, it is possible to absorb the horizontal fluctuations of the adjacent housings, and the multi-stage pipe is used instead of the panel-shaped wall portion, so that the structure is more compared to the above two examples. It is simple and lightweight, and there is an advantage that a movable amount can be obtained according to the purpose just by changing the length of the pipe. However, since the pipe is installed horizontally, it is easy for a child to climb using it as a foothold like a ladder. There is a problem in safety, etc., and it is unsuitable as a structure in a high place.
[0008]
Furthermore, as a handrail shape, pillars are erected with hinges at the ends of both housings so that they can be rotated, and the fixed ends are fixed to the upper and lower ends of both pillars, and horizontal fixing pipes are installed. The vertical pipes are installed at regular intervals between the upper and lower fixed pipes. Between the fixed pipes on both sides, movable pipes with both sides slidably inserted into the fixed pipes are arranged. A configuration is shown in which vertical members are attached at regular intervals between the movable pipes. According to this configuration, it is possible to absorb the fluctuation in the horizontal direction of the adjacent housing, and the use of the pipe makes the structure simple and lightweight, and a movable amount corresponding to the purpose can be obtained simply by changing the length of the pipe. Although there is an advantage, the stand must be arranged so that the stand of the fixed pipe and the stand of the movable pipe do not collide with each other when they approach each other. When the movable pipe is pulled out, the stand standing between the fixed pipe and the stand standing between the movable pipe are separated from each other, leaving a wide space, making it easier for the child to pass through. This is not suitable as a high-rise structure.
The horizontal fixed pipe can be installed only at the upper part of the pillar, and the lower part of the pillar can be made into a panel structure, but in this case, the structure is the same as the panel-shaped wall part, and the same problem can be solved. Can not.
[0009]
[Problems to be solved by the invention]

[0010]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides one handrail unit having a horizontal frame ridge and a vertical frame ridge and another handrail unit juxtaposed therewith, with at least a part of the front and rear surfaces of adjacent units. In parallel with each other, the opposite side surfaces of the horizontal frame of adjacent units are slid through a longitudinal slide structure including a center-expanded recessed groove and a corresponding bulged fitting protrusion. In a handrail-type expansion joint having a structure in which two or more juxtaposed units are connected to each other, and the vertical frame ridges at both left and right ends are connected to the adjacent housing side so as to be able to absorb fluctuations, the side on which the adjacent unit faces A slide core is formed by forming a concave groove having a widened middle shape on the side surface of the lateral frame ridge, and facing one of the opposed concave grooves with a swollen fitting projection substantially corresponding to the concave groove shape. The material is mated and fixed. Is characterized in that to constitute a handrail type expansion joints a protruding fitting projection of the core material fitted slidably to the other of the recessed groove.
In the above, the horizontal and vertical frame bodies are the upper and lower horizontal frame ridges and the vertical frame ridges at the left and right end portions, and a vertical element or plate having a predetermined pitch is disposed between the vertical frame ridges between the upper and lower horizontal frame ridges. It is preferable that the handrail unit is formed.
When the handrail type expansion joint is composed of two handrail units, the vertical frame ridges at the outer ends of each unit are connected to the adjacent housing side, respectively, and when the handrail unit is composed of three or more handrail units, The vertical frame rods at the outer ends of the left and right handrail units are respectively connected to the adjacent housing side, and the intermediate handrail unit is slidably connected to both handrail units on both sides.
[0012]
With the above configuration, the horizontal frame rod and the vertical frame rod are connected and fixed to each other as a handrail unit, and the juxtaposed unit can be assembled using a plurality of handrail units having the same shape. Therefore, if a long horizontal frame is cut and assembled to an arbitrary length, a handrail unit with a desired length and size can be obtained, and a handrail unit that appropriately matches any frame gap can be obtained. Obtainable. The structure and manufacture are simple, and at the same time, the continuous portions are continuous and the strength can be maintained high. If the slide core material is used, the entire horizontal frame is supported, and by sliding in the groove of the opposing horizontal frame, it is excellent in variable functionality and stably supports the connection state between the handrail units. Resulting in juxtaposed units.
Each of the vertical members provided between the frame rods can maintain the safety of the handrail without being constantly changed even when the housing gap fluctuates and the handrail unit moves.
