Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to improvements in curtain walls, particularly curtain walls that hold window materials and wall materials in mullions and horizontal beams.

As a conventional curtain wall, for example, an aluminum curtain wall is known.
In this aluminum curtain wall, the mullions and horizontal bars are each formed from extruded aluminum members. Then, mullions are provided continuously in the vertical direction at predetermined intervals on the exterior of the building, horizontal bars are combined between the mullions to form a rectangular frame, and window materials, wall materials, etc. are held within this rectangular frame. Furthermore, a seal is formed between the mullions and horizontal bars and the window material and wall material.

However, in such conventional curtain walls, the entire mullions and horizontal bars are made entirely of aluminum, so corrosion resistance is good, but if the entire mullions and horizontal bars are made entirely of aluminum, The cost is high because aluminum is a relatively expensive material, and in order to support the load of window materials and wall materials with such aluminum mullions and horizontal bars, the inside part of the mullion, which is mainly the load-bearing part, is required. In other words, it is necessary to increase the estimated dimensions of the part of the mullion located towards the inside of the building compared to the window and wall materials, to increase the cross-sectional moment of the inside of the mullion, and to obtain sufficient strength. As a result, the distance between the window material, wall material and the building's exterior surface is limited by the estimated dimensions of the mullioned inner part and has to be increased, resulting in wasted space and furthermore, due to the construction site conditions. There was a problem in that it was difficult to easily adapt it to the construction conditions even if there were various changes.

For this reason, in the past, mullions and horizontal bars were each made of an outer member and an inner member, and aluminum profiles were used for the outer members, which were more likely to corrode, and steel profiles were used for the inner members, which were less likely to corrode. It is known that it was made to use . In the above and following explanations, outer members refer to the parts that are exposed to the outside from the window and wall materials, and inner members are those located closer to the building than the window and wall materials. refers to the parts that However, in this case, although it is possible to reduce costs by reducing the amount of aluminum used, the degree of freedom in selecting dimensions is limited because the steel shapes are standardized, and the dimensional ratio between the web part and the flange part is constant, so the expected If you try to increase the dimensions of the web part, the dimensions of the flange part will become larger than the outer member, which will require adjustment, and since the shaped steel material is originally a structural material, it is heavy, and the curtain It is difficult to use it as a finishing material for walls, etc., and furthermore, the structure of the connecting parts of the mullion and horizontal beams must be complicated.

This invention was made by focusing on such conventional problems, and it combines horizontal bars between mullions that are continuously provided vertically at predetermined intervals on the exterior of a building, and windows are installed within the rectangular frame. The above-mentioned mullions and horizontal bars in the curtain wall that can freely hold wood and wall materials are each formed of an inner member made of steel and an outer member made of aluminum, and in the case of the mullions,
The outer member has a pipe shape with a pair of connecting flanges extending in the longitudinal direction, and the inside thereof is a vertical drainage channel, the inner member has a pipe shape consisting of a combination of a main member and an auxiliary member, and the inner and the outer members are connected by fitting a connecting member provided on the auxiliary member between a pair of connecting flanges, and in the case of the horizontal beam, the outer member has an upper surface that is connected to the vertical member. A through member having a U-shaped receiving part which is a part of the horizontal drainage channel communicating with the lateral drainage channel is provided, and the inner member is provided with a U-shaped connecting member, and the inner and outer members are provided with a U-shaped connecting member. By connecting both members by fitting the U-shaped connecting member into the U-shaped receiving part,
The purpose is to solve the above conventional problems.

The present invention will be explained below based on the drawings. 1 to 8 are diagrams showing one embodiment of the present invention. In the figure, 1 is a mullion, which is continuously provided in the vertical direction on the outer surface 2 of the building at predetermined intervals. 3 is a horizontal crosspiece, which is combined with the mullion 1 above. A rectangular frame 6 for holding glass 4 as a window material or panel 5 as a wall material is formed on the outer surface 2 of the building by these mullions 1 and horizontal beams 3. In addition, the mullion 1 and the horizontal beam 3 have inner members 7, 8 and outer members 9, respectively.
10, and between these inner members 7, 8 and outer members 9, 10, the edge of the glass 4 or panel 5 is made of a sealing material 11, an adhesive 12, or a hard rubber material. It is held via a spacer 13 or the like. Furthermore, the inner members 7 and 8, which are not often exposed to rainwater, etc. but are required to have load-bearing strength, are made of high-strength steel plates, and the outer members, which are not required to have much load-bearing strength, are exposed to rainwater, etc. By making parts 9 and 10 made of highly corrosion-resistant aluminum, the characteristics of each material can be utilized efficiently and costs can be reduced. Further, the inner members 7 and 8 made of steel plates are bent using a bender or the like. That is, the expected dimension l of the inner members 7 and 8 can be set in advance according to the conditions of each construction site to a dimension that has a load supporting strength that meets the conditions. Specifically, the inner member 7 of the mullion 1 is formed into a rectangular tube shape by a main member 14 whose prospective dimension l can be freely set according to the load supporting strength and a width support member 15 welded to the main member 14. It is formed. In this way, by forming the inner member 7 separately into the main member 14 and the auxiliary member 15, it becomes very easy to bend the inner member 7 in accordance with the conditions of each construction site. Moreover, compared to the conventional case of using ready-made shaped steel materials, the space between the building exterior surface 2 and window materials and wall materials can be minimized, thereby minimizing wasted space. A bracket 16 for connecting the horizontal beams 3 is fixed to the main member 14 via bolts and nuts 17, and an L-shaped connecting member 18 for the outer member 9 is welded to the auxiliary member 15. This inner member 7 is fixed to a bracket 46 supported by base materials 45a and 45b on the building side via bolts and nuts 47, and its position can be adjusted freely through elongated holes 48 of the bracket 46. Moreover, the inner member 8 of the horizontal crosspiece 3 is
Estimated dimensions l corresponding to the inner member 7 of the mullion 1 above
It is formed into a U-shaped cross section and is fixed to the bracket 16 via screws 19.
A U-shaped connecting member 21 is welded in advance to the outer surface 20 of the inner member 8 along its longitudinal direction. The inner members 8 are each fixed to a base material 22 disposed on the outer surface 2 of the building via screws 23.
The aluminum outer members 9, 10 are each formed from a one-piece extrusion section. Specifically, the outer member 9 of the mullion 1 has a rectangular pipe shape, and a pair of connecting flanges 25 that fit with the connecting member 18 of the inner member 7 are provided on the inner surface 24 of the mullion 1 in the longitudinal direction. This connecting flange portion 25 and the connecting member 18 are connected by bolts 26. In this way, by connecting the inner member 7 and the outer member 9 through the fitting structure between the connecting member 18 and the pair of connecting flanges 25, the workability is extremely excellent. . Although the outer member 9 has a rectangular pipe shape with a flat outer surface 26, various pipe shapes other than the rectangular shape can be adopted, and the outer surface 26 is not limited to being flat. Outer member 1 of horizontal bar 3
0 has a flat plate shape and is connected to the inner member 8. Between the outer member 10 and the inner member 8, there is a through member that passes between the outer member 9 and the inner member 7 of the mullion 1. 27 is interposed. Specifically, the through member 27 has a U-shaped receiving portion 27.
a and the U-shaped connecting member 21 are fixed with screws 29 in the fitted state, and this through member 27
The outer member 9 is fixed to the outer member 9 via bolts 30.
In this way, by connecting the inner member 8 and the outer member 10 with the fitting structure of the U-shaped receiving part 27a and the U-shaped connecting member 21, the workability is improved and the upper and lower parts of the building can be This provides sufficient strength to withstand loads applied in different directions. In addition, the connecting member 18 of the inner member 7 and the connecting flange portion 25 of the outer member 9 in the mullion 1 each have a through member 27.
Notches 31 and 32 for penetration are formed. Furthermore, sealing materials 40 are provided between the inner member 7 and the through member 27 and between the outer member 9 and the through member 27, respectively.
is interposed. A horizontal drainage channel 33 is formed on the upper surface of the through member 27, specifically, on the upper surface of the U-shaped receiving portion 27a. Furthermore, a water collection hole 34 communicating with the horizontal drainage channel 33 is formed at a position corresponding to the intersection with the horizontal beam 3 in the outer member 9 of the mullion 1, and a water collection hole 34 is formed in the lower part of the outer member 9 to communicate with the outside. A drainage hole 35 is formed to form a vertical drainage channel 36 inside the outer member 9. Note that the lower end of the outer member 9 is closed with a filling 42. Therefore, the horizontal drainage channel 33 and the vertical drainage channel 36 communicate with each other, and the rainwater that has entered the rectangular frame 6 can be reliably discharged to the outside for each floor. Furthermore, 37 is the floor position, 38 is the fireproof panel, 39 is the window opening, 41 is the joint material of the outer member 9, and 43 is the setting block.
This setting block 43 has a drainage groove 4.
4 is formed.

Next, the effect will be explained. First, when assembling the curtain wall, the inner members 7 and 8 of the mullions 1 and the horizontal beams 3 are processed in advance to have an expected dimension l that has a load-bearing strength according to the construction conditions of the building. In this case, the dimensions of the inner members 7 and 8 can be freely set by bending the steel plates with a bender or other means. Therefore, it is easy to obtain the optimum dimensions for the construction conditions of the building, and there is no waste of materials. Economical. Next, the inner members 7 of the mullions 1 are vertically arranged on the building exterior surface 2 at predetermined intervals and fixed to the base material 22.
In this case, the upper and lower ends of the inner member 7 are at floor position 2, respectively.
It is located corresponding to 7. Then, the inner member 8 of the horizontal crosspiece 3 is suspended and fixed between the brackets 16 that protrude from the inner member 7 at positions corresponding to the upper and lower edges of the window opening 39, and the inner member 8 is fixed to the base material 22. sticks to. In this case, the inner member 8 on the upper edge side of the window opening 39 is provided in an upwardly open state, and the inner member 8 on the lower edge side is provided in a downwardly open state to serve as a window sill. A connecting member 21 is welded to the inner member 8 in advance at the factory, and a through member 2 for passing through the mullion 1 is further attached to this connecting member 21.
Fix 7. And the inner member 7 of the mullion 1
The outer members 9 and 10 made of aluminum are respectively fixed to the through member 27 to form a rectangular frame 6, and the glass 4 or A curtain wall can be easily formed by inserting the edge of the panel 5 and applying sealant 11, adhesive 12, spacer 13, etc., and performing this process on each floor. Note that a joint material 41 is applied when connecting the outer members 9 in the vertical direction. Further, at the same time as the rectangular frame 6 is formed, a horizontal drainage channel 33 is formed on the upper surface of the through member 27, specifically, on the upper surface of the U-shaped receiving part 27a, and the drainage channel 33 is formed inside the outer member 9. Since a communicating vertical drainage channel 36 is formed, even if poor construction or deterioration of the sealing material 11 occurs at any position on the rectangular frame 6, rainwater will not enter the building side.
Water can be reliably drained to the outside at each floor location. Furthermore, since the outer member 9 has a sufficient length, a sufficient hydraulic head can be obtained, and as a result, it is possible to prevent rainwater from flowing backward from the drainage hole 35, so that excellent watertightness can be obtained without the need for flushing or the like. This is the result.

The above explanation assumes that a curtain wall will be formed on the exterior of a newly constructed building, but this example is not limited to this example. is also fully applicable.

Since this invention is as described above, the following effects can be expected.

(b) Since the mullions and horizontal beams are each made of an inner member made of steel plates and an outer member made of aluminum, the inner members are bent in advance to correspond to the estimated dimensions according to the design conditions of the building. This allows each member to be made as small and lightweight as possible while providing the necessary strength. As a result, it is possible to eliminate wasted materials, and compared to the conventional case of using ready-made steel shapes, the space between the building exterior and window materials and wall materials is minimized, minimizing wasted space. be able to.

(b) Both the inner and outer members of the mullions and horizontal bars are connected by a fitting structure between a connecting member and a connecting flange, or a fitting structure between a U-shaped connecting member and a U-shaped receiving part. Therefore, it is easy to connect both the inner and outer members, and excellent connection strength can be obtained.

(d) The inner member for the mullion, which has a pipe shape that is preferable in terms of strength, is formed by a combination of the main member and the auxiliary member, and the auxiliary member is provided with a connecting member, so the pipe shape is relatively complicated. The bending process and the assembly of the connecting member become easier, and workability is improved.

(E) A vertical drainage channel is formed inside the outer member of the mullion, and a horizontal drainage channel is formed in the through member for connecting both the inner and outer members on the horizontal crosspiece, and these drainage channels are made to communicate with each other. Although the structure is simple, drainage can be ensured on each floor.

(F) The through member, which is also used to connect both the inner and outer members of the horizontal beam, is also used to form a drainage channel in the horizontal direction, so the two functions of connecting both the inner and outer members and forming a drainage channel can be achieved with an extremely simple structure. This will improve workability.
