Description

  The present invention relates to an eaves ridge connection structure, and more specifically, increases the strength of the connection portion between the eaves ridge and the water collector, and uses a bracket that supports the eave ridge without deformation of the connection portion due to snow or heavy rain. The present invention relates to an eaves connection structure that can reduce the number and reduce the mounting work of the bracket.

  The eaves installed on the roof of the house is supported by a bracket that is an eaves metal fitting, fixed to the eaves board, the end of the eaves is connected to the water collector, and rainwater is connected to the lower part of the water collector. It is made to drain into the drainage ditch or the water storage tank from the reinforced solid.

  This water collector has a portion that overlaps with the eaves so that when the eaves expands and contracts, the connecting portions slide against each other to prevent the eaves from being detached or damaged. And this connection part is easy to deform | transform, such as bulging ahead by heavy snowfall, heavy rain, etc., and sufficient intensity | strength is required.

  Conventionally, in order to reinforce this connecting portion, the water collector is suspended and supported by a copper wire or the like, or the snow load is reduced by lowering the mounting position of the eaves rod. However, even if the water collector is hung with copper wire etc., it does not strengthen together with the eaves, so it is not possible to prevent each other's displacement, while if the eaves are lowered, the eaves are included Not only is the overall design change required, but there is also a design problem.

  For this reason, focusing on the front ear piece that lifts the upper end of the eaves bowl on the outside and the bracket that fixes the eaves bowl to the eaves nose cover, efforts have been made to improve the shape and structure of the front ear piece and bracket of the eaves bowl. ing.

  For example, Patent Document 1 discloses an eaves-holding structure in which an eaves-holding structure is locked to a bracket that is provided at an appropriate interval from a fixed base attached to a side wall of a building. It is proposed that the bracket is fixed to have a two-stage configuration. This allows the bracket to withstand greater loads. However, even such a bracket structure cannot be reinforced because it is not attached to the connecting portion between the eaves and the eaves.

  For this reason, increasing the number of brackets used, that is, reducing the bracket mounting interval in the vicinity of the connecting portion is considered as a realistic countermeasure.

That is, as shown in FIG. 4, the brackets 3 and 3 ′ are attached at positions close to each other. As a result, the distance between the brackets 3 and 3 ′ is usually 40 cm or less and sometimes 30 cm or less at the connection portion, and in order to take a gradient near the edge 48 of the eaves, such as the corner of the roof. Since it is necessary to attach the bracket 3 ″, the brackets 3 ′ and 3 ″ exist at a shorter distance.
In order to increase the strength of the connecting part, the pitch of the eaves brackets (brackets) must be narrowed, but there is a limit because the width of the water collector cannot be reduced. Moreover, shortening the bracket mounting interval increases the number of brackets used, which not only increases the number of attachment work to the eaves, but also impairs the beauty.

In recent years, abnormal weather conditions have been severe, and it is expected that torrential rain and heavy snow will intensify. The current eaves connection structure is far from sufficient, and new solutions have been demanded.
JP 9-189104 A

  In view of the problems of the prior art, the problem of the present invention is to increase the strength of the connecting portion between the eaves and the water collector, and to use the bracket that supports the eaves without deformation of the connecting portion due to snow or heavy rain. An object of the present invention is to provide an eaves connection structure that can reduce the number and reduce the mounting work of the bracket.

  As a result of intensive research in order to solve the above-mentioned problems, the present inventor made use of a bracket locking groove on the outdoor front ear portion of the eaves bowl, and attached a bar-shaped reinforcing tool to the longitudinal direction of the groove. If the eaves bowl and the water collector are connected together, the strength of the connection area between the eaves bowl and the water collector will be greatly reinforced, and the connection area will be deformed even if a large load is applied. It has been found that it becomes difficult, and the present invention has been completed.

  That is, according to the first invention of the present invention, an eaves bowl having a locking groove for a bracket inside the front ear part, and an eaves bowl inserted by inserting an end part of the eaves bowl into a side wall insertion opening provided on the side wall. An eaves ridge connection structure having a water collector to be connected, wherein eave ridges are connected to both sides of the water collector, and the eave ridges are connected to each other by a bar-shaped reinforcing tool inserted into the locking groove. An eaves connection structure characterized by the above is provided.

  According to the second invention of the present invention, in the first invention, the bar-shaped reinforcing tool is inserted into the locking groove from the eaves-rod insertion port outward to a predetermined range. An eaves connection structure is provided.

As described above, the eaves connection structure of the present invention attaches the reinforcing tool to the connecting portion between the water collector and the eaves so that the strength is enhanced. As a result, a large amount of rainwater flows through the eaves in a short time. Even if a large amount of snow is piled up or a large amount of snow is applied, or stress is applied in a complicated direction due to an earthquake, there is an effect that it is possible to avoid the risk of breaking the connection between the eaves and the water collector.
Moreover, the rod-shaped reinforcing tool to be used can be manufactured relatively easily and can be easily attached to the portion of the connecting portion to be reinforced.

  Also, in the past, in order to reinforce the connection part, the brackets were attached to the eaves with the distance between the brackets close to the left and right of the water collector so that the water gradient did not go wrong. Since the reinforcing tool is used, it can be easily inserted into the connecting portion and strengthened, and the bracket mounting interval can be widened. As a result, the number of brackets used can be reduced, dangerous mounting work at high locations can be reduced, and the aesthetics can be increased.

  Hereinafter, the eaves connection structure of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the eaves-rod connection structure of the present invention, and is a perspective view showing a state in which a reinforcing tool is inserted into the connection portion between the water collector and the eaves wall. FIG. It is a side view when cut along line -A. FIG. 3 is a plan view (B) of the present invention. FIG. 4 is a plan view showing a state where the connecting portion between the water collector and the eaves is reinforced only with a bracket, which is a conventional example.

  The eaves are mainly made of hard vinyl chloride integrally molded by an extrusion method, but expands and contracts due to temperature changes. Therefore, the eaves basket 4 is connected to the water collector 5 with a stretchable part.

  That is, when the end of the eaves is inserted into the eaves insertion port 6 provided on the side wall of the water collector 5 and the eaves 4 is connected, the connecting portion is in a state where the two plates overlap. The length of the connecting portion is appropriately determined depending on the eaves, the size of the water collector, the support capacity of the bracket, the amount of rainfall, the amount of snowfall, the wind force, etc., but is 5 to 20 cm, preferably 5 to 10 cm. The connection part is simply a stack of plates. For example, if a large amount of snow accumulates in the connection part due to heavy snow, a large force is applied in the direction of the front wall of the eaves wall, and twisting stress is applied to the eaves wall from the bracket 3. It will come off and the connection will be destroyed.

  For this reason, in this invention, in order to raise the intensity | strength of the connection part which the eaves basket 4 and the water collector 5 overlap, the specific rod-shaped reinforcement was attached to the specific position, and the reinforcement part 1 was comprised.

  In the present invention, the rod-shaped reinforcing tool 10 is an elongated and rigid rod-shaped body having a sufficient length. As the material, for example, a metal such as aluminum, stainless steel, steel, or titanium, or a synthetic resin such as hard vinyl chloride or polycarbonate can be used. A metal rod-like body having high rigidity is preferable. Moreover, even if it deform | transforms temporarily, the shape memory alloy which has the property which returns to an original shape by a temperature change etc. can be employ | adopted, or an outer periphery can be coat | covered with rubber | gum etc. and friction can also be raised. In the case of a synthetic resin, carbon fiber, glass fiber, aramid fiber, or the like may be blended to increase rigidity, or a composite material with these woven fabrics may be used.

  Examples of the shape of the bar-shaped reinforcing tool 10 include an elongated round bar, a polygonal bar-shaped body such as a triangular or square cross section, a U-shaped bar-shaped cross section, and an L-shaped bar-shaped cross section. These may be solid or hollow.

  In many cases, the front ear portion 21 on the outdoor side of the eaves basket 4 has a locking groove 2 having a cross-sectional shape as shown in FIG. If it is such an eaves bowl, it is preferable that the bar-shaped reinforcing tool 10 is a cross-sectional U-shaped bar-shaped body or a cross-sectional L-shaped bar-shaped body whose cross-sectional shape is similar to the locking groove 2 of the outdoor side ear | edge part of the eaves basket 4. This is because it can be easily inserted into the locking groove 2 in the front ear portion of the eaves and is difficult to come off once inserted.

  The bar-shaped reinforcing tool 10 must be long enough to cover at least the connecting portion between the eaves 4 and the water collector 5. That is, it is necessary for the bar-shaped reinforcing tool 10 to cross the upper wall surface of the water collector 5 from one eaves tub insertion port 6 and exceed the other eaves tub insertion port. The total length is 10-50 cm, and 15-30 cm is more preferable. Thereby, sufficient reinforcement strength can be provided without making insertion into the locking groove difficult.

  The thickness of the rod-shaped reinforcing tool 10 is set to a dimension that is equal to or slightly smaller than the width of the locking groove 2 of the eaves hook front ear portion 21. It is not necessary to have a uniform thickness over the entire length, but if there is an excessively thin part in the middle, it will be bent, which is not preferable. The surface state may be smooth, but if the surface is roughened or roughened, the frictional force with the eaves can be increased in the locking groove 2 and it is difficult to come off. A string or a small protrusion (a knob) can be provided on a part of the outer periphery of the rod-shaped reinforcing tool 10 to facilitate attachment and extraction.

  By attaching the bar-shaped reinforcing tool 10, the brittle connection portion is strengthened, and together with the brackets 3, 3 ′ on both sides orthogonal to the longitudinal direction of the heel, a strong two-point support is formed.

  Next, the construction method to reinforce the connecting part of the water collector and eaves is described. First, a sufficiently long bar-shaped reinforcing tool 10 is prepared so as to fit the locking groove in the front ear portion of the eaves bowl, and the bar-shaped reinforcing tool 10 is inserted as shown in FIG.

  The bar-shaped reinforcing tool 10 is attached in the locking groove 2 of the front ear 21 of the front wall of the eaves wall and is inserted so as to cross the upper surface of the wall surface of the water collector 5. It is desirable that the locking groove is inserted to a predetermined range outward from the eaves bag insertion opening. At this time, it is desirable that the bar-shaped reinforcing tool 10 constitutes the reinforcing portion 1 at a substantially equal distance from side to side with respect to the center line AA of the connection portion. Since the frictional force increases and the strength increases as the contact portion between the bar-shaped reinforcing tool 10 and the eaves rod 4 becomes longer, it is more preferable that the contact portion is 3 cm or more on both the left and right sides and 5 cm or more can be secured. If the reinforcing tool is inserted on either the left or right side of the eaves, sufficient strength may not be maintained.

Next, two brackets are attached to both sides of the connecting portion. The bracket is attached at a position outside the connecting portion so that the head is inserted into the front ear of the eaves and straddles the rear ear. According to the present invention, since the strength of the connecting portion is increased as compared with the conventional case by inserting the bar-shaped reinforcing tool 10, the installation interval between the two brackets 3 and 3 ′ exceeds 50 cm and is within 90 cm, preferably 60 cm. It can also be spread within 80 cm.
The eaves eaves 4 are secured to the eaves nose concealment plate 34 by holding the front ear 21 and the rear ear of the eaves eave 4 with the tip or the rear end of the bracket 3 or lifting the eaves eaves 4 at the base of the bracket 3. Attach to.

  In addition, the connection cylinder part 7 etc. are provided in the lower part of the water collector 5 as components for a connection with a basket. Moreover, the stopper 46 is attached to the edge part of the eaves bowl inserted in the connection part of a water collector, and an eaves bowl does not detach | leave from the connection part of a water collector, but can prevent the leakage of rain water.

  The eaves connection structure of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this, and the present invention can be changed even if there is a design change or the like without departing from the object of the present invention. included. For example, instead of hanging the eaves with a bracket, the lower part of the eaves may be supported by a receiving tool. In addition, it is possible to retrofit a bar-shaped reinforcing tool to an already installed eave ridge instead of installing a new eave ridge on the roof.

It is the perspective view of the state which showed the eaves connection structure of this invention, and inserted the reinforcement tool in the connection part of a water collector and an eaves. It is a side view when the connection part of FIG. 1 is cut | disconnected by the AA line. It is a top view of the eaves connection structure of this invention. It is a conventional eaves connection structure, and is a top view which shows the state which reinforced the connection part of a water collector and eaves only with a bracket.
