Description

Technical Field

[0001] The utility model relates to the field of curtain wall engineering construction, in particular to a pressing block used in curtain wall construction technology. Background Art

[0002] At present, the existing frame-type hidden frame glass curtain wall has two connection forms with the sub-frame of the glass hollow layer structural glue, one is installed behind the glass, and the other is installed in the glass hollow layer. For the glass hollow layer installation method, when installing the curtain wall, the glue seam width between two adjacent glass pieces generally cannot be greater than 20mm. According to the glass curtain wall installation specification, in order to ensure that the glass is not damaged, the distance between the glass and the keel frame or the pressure block cannot be less than 5mm. In this case, the middle thickness of the pressure block is required to be no more than 10mm. The existing pressure blocks can basically meet the requirements on the basis of ensuring the firmness. In order to achieve the overall effect of curtain wall construction, the requirements of many curtain wall construction projects are constantly increasing. The width of the hidden frame glue joint is required to be smaller and smaller, reduced to 16mm or even 15mm, and a minimum of 5mm space from the keel frame or the pressure block must be reserved on both sides. At this time, the thickness of the middle of the pressure block is required to be 6mm at most, and the existing pressure blocks are generally π-shaped, and the pressure block legs must occupy a certain thickness. If the thickness of the pressure block legs is too thin, the pressure block cannot be supported to fix the glass curtain wall. The screws commonly used to fix the pressure blocks are M6 screws with a diameter of 6mm. A safety distance of 5cm must be reserved on both sides of the pressure block. The screws and the safety distance have occupied 16mm. For the glue joints with an interval of 16mm, there is no extra space for the existing pressure block legs, and it is impossible to accommodate sufficient leg thickness. Therefore, the pressure block structure must be improved to solve this problem. Utility Model Content

[0030] In an optional embodiment of the present invention, a vertical projection of the first supporting leg 5 is located inside the pressing surface 1 and outside the fixing hole 2 .

[0031] Specifically, in this embodiment, the first support leg 5 is a flat plate, the area of ​​which is smaller than half of the area of ​​the pressing surface 1, the center of which is located at the vertical intersection with the first support leg 3, the width of which is smaller than the width of the pressing surface 1, and the height of which is smaller than the distance between the fixing hole 2 and the upper and lower edges of the pressing surface 1; for example: the width of the first support leg 5 is 1 / 3 of the width of the pressing surface 1; at the same time, the first support leg 5 cannot be within the radial space of the fixing hole 2, so as to leave space for the bolt 7 to penetrate the fixing hole 2 to the keel 8, so that the bolt 7 can be tightened and fixed with the bolt nut reserved in the keel 8.

[0034] In an optional embodiment of the present invention, a vertical projection of the second supporting leg 6 is located inside the pressing surface 1 and outside the fixing hole 2 .

[0035] Specifically, in this embodiment, the second support leg 6 is a flat plate, the area of ​​which is smaller than half of the area of ​​the pressing surface 1, the center of which is located at the vertical intersection with the second support leg 4, the width of which is smaller than the width of the pressing surface 1, and the height of which is smaller than the distance between the fixing hole 2 and the upper and lower edges of the pressing surface 1; for example: the width of the second support leg 6 is 1 / 3 of the width of the pressing surface 1; at the same time, the second support leg 6 cannot be within the radial space of the fixing hole 2, so as to leave space for the bolt 7 to penetrate the fixing hole 2 to the keel 8, so that the bolt 7 can be tightened and fixed with the bolt nut reserved in the keel 8.

[0036] In an optional embodiment of the present invention, the pressing block is made of aluminum alloy profiles.

[0037] Specifically, the material of the pressing block of the utility model is a strong, durable, economical and practical profile that can meet the construction requirements of glass curtain wall installation, and is preferably a light and strong aluminum alloy profile.

[0038] In an optional embodiment of the present invention, both the first supporting leg 3 and the second supporting leg 4 are support plates with a preset thickness.

[0039] Specifically, the first leg 3 and the second leg 4 need to provide support for fixing the curtain wall glass. In order to achieve the purpose of firm fixation, the thickness of the two legs cannot be too thin, and a certain thickness is required to provide sufficient support for the installation of the curtain wall glass. At the same time, due to the increasingly high requirements for the existing curtain wall installation and construction, many projects require the glue seam width between two adjacent curtain wall glasses to be reduced from the original 20mm to 16mm. According to the glass curtain wall installation specifications, in order to ensure that the curtain wall glass is not damaged, the distance between the curtain wall glass and the keel frame or the pressure block cannot be less than 5mm. At this time, the thickness of the middle of the pressure block is required to be no more than 6mm. The screws commonly used to fix the pressure block are M6 screws, and the diameter of the M6 ​​screws is 6mm. Therefore, the thickness of the first leg 3 and the second leg 4 cannot be too thick, and the maximum thickness cannot exceed 6mm.

[0040] In an optional embodiment of the present invention, the preset thickness of the first supporting leg 3 and the second supporting leg 4 is 4.4 mm.

[0041] Specifically, in order to meet the construction requirement that the width of the glue joint between two adjacent curtain wall glasses is no more than 16 mm, the preset thickness of the first supporting leg 3 and the second supporting leg 4 cannot exceed 6 mm, preferably 4.4 mm.

[0042] In an optional embodiment of the present invention, the diameter of the fixing hole 2 is a preset value.

[0043] Specifically, the bolts passing through the fixing holes 2 need to provide support for fixing the curtain wall glass. In order to firmly fix the glass curtain wall, the diameter of the bolts passing through the fixing holes 2 cannot be too small, and a certain thickness is required to provide sufficient support for the installation of the curtain wall glass. At the same time, due to the increasingly high requirements for the existing curtain wall installation and construction, many projects require that the width of the glue seam between two adjacent curtain wall glasses be reduced from the original 20mm to 16mm. According to the glass curtain wall installation specifications, in order to ensure that the curtain wall glass is not damaged, the distance between the curtain wall glass and the keel frame or the pressure block cannot be less than 5mm. At this time, the thickness of the middle of the pressure block is required to be at most 6mm. Therefore, the aperture of the fixing hole 2 cannot be too large, and the maximum diameter cannot exceed 6mm.

[0044] In an optional embodiment of the present invention, the preset value of the diameter of the fixing hole 2 is 6 mm.

[0045] Specifically, in order to meet the construction requirement that the width of the glue joint between two adjacent curtain wall glasses is no greater than 16 mm, the preset value of the aperture of the fixing hole 2 cannot exceed 6 mm, preferably 6 mm.

[0046] The clamp is made of metal profiles. During processing, a slit is first cut in the middle of the profile to facilitate the production of the fixing hole 2. The line between the two legs of the clamp and the keel 8 is consistent with the length direction of the keel; the two legs have a certain width, which can solve the problem of insufficient bending resistance of the single-sided clamp; the thickness of the two legs in the vertical seam width direction is 4.4mm, and the distance between the end of the curtain wall glass and the clamp is 5.8mm, which meets the requirements of the glass curtain wall installation specification. During installation, after the curtain wall glass is in place, slide the clamp down from the upper end of the curtain wall glass and tighten the screws to fix it.

[0047] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
