Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure of a head tree that is attached to the end portion, the rising portion of a building, the rising top portion of a parapet, and the like.

(Prior art) Conventionally, the headstock to be attached to the rising top end of the parapet is
As an example, the structure is as shown in FIG.

That is, the holder 8 in which the lower folding plates 81, 81 for fitting and supporting the main body of the Sasaki is formed on both sides of the parapet of the substrate having the required width fixed to the top end corresponds to the vicinity of both ends and the middle of the main body of the Sasaki. It is fixed to the top end at appropriate intervals, and at the position corresponding to the joint part of the main body of the tree, uneven ridges 11 are provided in the width direction of the parapet in order to drain the water that has entered from the joint 10 between the bodies 9 and 9. A large number of draining plates 12 are arranged between the holders 8 and 8, and both sides of the upper surface having a width for covering the top end are bent downward along the parapet side surfaces to form lower folding surfaces 91, 91. The head body 9 having the lower end portion formed with an engaging protrusion 92 for engaging the lower folding plate 81 of the holder is fitted into the holder 8, and the joints of the head bodies 9 and 9 have a longitudinal direction. Adjust the expansion and contraction so that it can expand and contract due to temperature changes. Joint 10 to have been formed.

(Problems to be solved by the invention) However, since one Kasagi main body is fitted with several holders in the vicinity of both ends and in the middle, the fitting force (sliding) at the fitting portion of each holder The dynamic expansion and contraction is different, and the expansion and contraction regulated by the mating part with a strong mating force will cause a large expansion and contraction in only one direction of the main body of the body over the mating part with a weak mating force. Due to repeated expansion and contraction of the main body (arrow A in FIG. 6) due to changes in external conditions such as temperature and weather, and changes in the frame such as parapets, the main body does not expand and contract at a fixed position over time. In addition, there was a situation in which the position of the end portion of the main body of the Kasaki moved out of the draining plate because it moved in one direction on the holder. For this reason, the water that infiltrates from the joint of the Kasagi body
It did not flow to the draining plate, and penetrated into the body along the top of the parapet, causing water leakage.

Therefore, the present invention has been made in view of the above problems, and an object thereof is to eliminate the positional displacement due to the expansion and contraction of the main body of the tree, and to prevent the water leakage from the joints of the body of the tree to the frame.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention is to fix a headrest main body holder to a rising top end of a parapet at proper intervals and to drain water inside the joint position of the headstock body. In a headstock in which a drainer plate is arranged and the headstock body is fitted in a holder, the headstock body may be loosened or loosened so that movement of the headstock body in the longitudinal direction is restricted with respect to at least one of the holders. It is characterized in that it is tightly locked or fixed, and the head tree main body is fitted on the holder so that the head member main body can be freely expanded and contracted in the longitudinal direction with the locking or fixed portion as a restricting position to form the head tree.

In the above description, the head body may be loosely or tightly locked or fixed to the holder near one end or an intermediate portion thereof, and the head body may be telescopically fitted to the holder in the other end direction or both end directions. it can.

Further, the head board main body may be loosely locked or fixed to the holder in the vicinity of both ends thereof so that it can be expanded and contracted within a predetermined width.

(Example) Next, the Example of this invention is described according to drawing.

A first embodiment is shown in FIGS. 1 and 2. FIG. 1 is a perspective view showing a joint portion of a head tree attached to the top portion 1 of the parapet. The headstock is fitted to the holder 3 fixed to the top end portion 1 at appropriate intervals, the draining plate 4 disposed between the holders at the joint position of the headstock main body 2 covering the entire top end portion 1, and the holder 3. The main body 2 is formed by

The holder 3 is made of aluminum, and the lower folding plates 32, 32 into which the main body 2 is fitted are formed in a slightly downward opening on both sides of the substrate 31 having a required width extending in the width direction of the top end surface of the parapet top end portion 1. And the upper parts 33, 33 of the lower folding plates 32, 32
Are formed so as to be slightly higher than the substrate 31 and project so as to give a water gradient to the upper surface of the main body 2.
An elongated hole 34 that is long in the longitudinal direction of the head tree is formed on the lower surface of at least one of the lower folding plates 32 of the reference numerals 2, 32.
The holder 3 is fixed to the parapet top end portion 1 with anchor bolts at an interval such that the draining plate 4 can be arranged at a position corresponding to the seam portion of the main body, and the others are fixed at appropriate intervals. There is.

The draining plate 4 is provided with bent portions 42, 42 which are attached to the parapet top end portion 1 and are bent downwards on both sides of a substrate 41 of a required width that is inclined in one direction of the parapet. Bend 4 on the water gradient side that is continuous with it
On the surface of No. 2, a large number of concave-convex strips 6 for preventing water from flowing toward the holders 3 and 3 on both sides are formed in parallel with the width direction of the parapet, and the upper end of the other bent portion 42 is located above the substrate 41. Is also formed so as to project upward.

The Kasaki main body 2 has an upper surface 21 that covers the parapet top end portion 1.
On both sides of the lower folding plate 22, which is bent downward along the side surface of the parapet, and the lower folding plate 32 of the holder 3 is attached to the lower end portion thereof.
Engaging projections 23, 23 are formed on the lower folding surface 22, and a small hole 24 corresponding to the long hole 34 of the holder 3 arranged at one end of the main body 2 is formed on the lower folding surface 22. There is.

The above-mentioned body 2 is fitted into the holder 3 from above, and the engaging protrusions 23, 23 are attached to the lower folding plate 3 of the holder 3.
It is attached by elastically engaging the lower ends of 2, 32. At this time, the joint between the headstock bodies 2 and 2 is located at the center of the draining plate 4, and the joints 5 are formed at intervals so that the expansion and contraction of the headstock bodies 2 and 2 on both sides of the joint can be adjusted due to temperature changes. I am doing it. Also, the Kasagi body 2
The small hole 24 and the long hole 34 of the holder 3 are fixed to each other by passing the rivet 7 at one end portion of the main body 2 or by a screw or the like.

In the above-structured headstock, the headstock body 2 itself expands and contracts and the parapet repeatedly expands and contracts due to changes in external conditions such as temperature and weather. At this time, since the one end of the headstock main body 2 is fixed to the holder 3, the headstock main body 2 does not move over the holder. For example, when the main body 2 is extended, only the fixed portion with respect to the holder 3 is set to a fixed position and the other portion is extended. Even when the main body 2 is contracted, the fixed portion is fixed, so the expansion and contraction is repeated at the fixed position. be able to. Therefore, the end of the main body 2 is always located above the draining plate 4 and does not come off from the upper surface. Therefore, the water entering from the joint 5 between the main bodies 2 travels through the draining plate 4 to the outside. Will surely be leaked to.

In addition, the long hole 34 of the holder 3 is formed by the lower folding plates 32, 3 on both sides.
2 may be formed respectively, in this case, the main body 2
Can be attached to either or both slots or both. Further, as shown in the above-mentioned embodiment, it is preferable that the long hole 34 is formed as a long hole long in the longitudinal direction of the headstock because it facilitates adjustment at the time of fixing. It is preferable that the small holes 24 formed in the main body 2 of the head are machined on site in correspondence with the position of the holder when the main body 2 is fitted into the holder. It can be installed and fixed to an appropriate holder. The small holes 24 may be formed in advance at the time of shipping. In this case, the fixing position of the holder has to be set to a predetermined size position. In addition, it is also possible to utilize the length of the long hole 34 of the holder 3 for expansion and contraction absorption of the headstock main body 2, and in this case, the fixation of the headhole main body 2 with respect to the holder 3 is performed loosely. The fixed position may be two or more places such as both ends thereof.

Next, another embodiment of the fixing means for the holder of the main body is shown. Lower folded surface 22a of the main body 2a shown in FIGS.
Protrusions 25, 25 are formed on the inner surface of the so that the lower folding plate 32a of one of the holders 3a is locked so as to be sandwiched from the longitudinal direction of the shed. Even if the headstock body 2a expands and contracts due to temperature changes and the like, since the projections 25 and 25 are locked to the holder 3a, it does not move and repeats expansion and contraction at a fixed position. Therefore, if a protrusion that engages with the holder is formed at one end or an intermediate portion of each headstock body in the same manner as described above, the joint position between the headstock bodies will not be separated from the draining plate.

Furthermore, another embodiment of the fixing means for the holder of the main body is shown in FIG. One lower folding plate 32b of the holder 3b
An engaging protrusion 35 extending downward is formed at the lower end portion, and a width portion of the engaging protrusion 35 is cut out at the lower end of the lower folding surface 22b of the headstock body 2b so that the engaging portion 26 of the engaging protrusion 35 is formed. Has been formed. When the headstock main body 2b is attached to the holder 3b, the engaging projections 35 of the holder 3b are engaged with the engaging portions 26 of the headstock main body 2b.
Since the headstock main body 2b does not move on the holder 3b, it does not move on the holder 3b. Therefore, the joints of the main body of the Kasaki do not come off from the draining plate.

The fixing or locking of the main body of the headstock to the holder is not limited to the lower folding plate of the holder, and may be set to be performed on the upper surface of the holder.

(Effects of the Invention) The present invention locks or fixes the headstock main body with respect to at least one holder so that the movement in the longitudinal direction is restricted, and at the same time, within the range where the above restriction is received, the length of the headstock main body is increased. It is characterized in that the body is fitted into the holder so that it can be expanded and contracted in any direction, so it is possible to guarantee free expansion and contraction adjustment of the body in accordance with changes in external conditions such as temperature and weather. At the same time, even if the Kasagi main body repeatedly expands and contracts, the Kasagi main body will not move and its end will not come off from the draining plate, and the body caused by the end of the Kasagi main body coming off the draining plate. It is possible to reliably prevent water leakage into the interior.
