Description

Technical Field

[0001] This utility model relates to the field of curtain wall sealing strip technology, and in particular to a Z-shaped sealing strip clamp for curtain wall structures. Background Technology

[0002] Curtain wall sealing strips refer to pre-formed elastic strip-shaped materials used in building curtain wall systems to fill and seal gaps between curtain wall panels, between curtain wall panels and supporting structures, or at other interfaces.

[0003] There is a type of curtain wall adhesive strip roll material with a Z-shape, such as Figure 1-2 As shown, the device includes a rubber strip body 1 with a Z-shaped cross-section and sealing blocks 2 on both sides of the rubber strip body 1. The rubber strip body 1 includes a straight support strip 3 in the middle and L-shaped connecting strips 4 symmetrically arranged on both sides of the straight support strip 3. The straight support strip 3 and the L-shaped connecting strips 4 on both sides form a Z-shaped structure and a U-shaped groove 5. A snap-fit ​​strip 6 extends vertically downward from the center of the bottom of the U-shaped groove 5. A connecting rib 7 extends outward from the top edge of the straight support strip 3. A semi-circular groove 8 is provided at the connection between the connecting rib 7 and the straight support strip 3. This connecting rib 7 is used to fix the geometry of the rubber strip (such as the Z-shaped U-shaped groove structure) during die-cutting or extrusion molding, preventing it from deforming or shifting during cutting, transportation, or assembly. At the same time, the setting of the connecting rib allows the rubber strip to be produced in continuous roll form, which is convenient for assembly line cutting and packaging. However, before actual installation, the rubber strip needs to be cut at the semi-circular groove 8 with a tool to remove this connecting rib. Figure 3-4 As shown, the current method for cutting this connecting bar is mainly to have the operator hold the adhesive strip with one hand and cut it with a knife with the other, which has problems such as difficult operation, low safety, and poor work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a Z-shaped adhesive strip clamp for curtain wall structures to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A Z-shaped adhesive strip clamp for curtain wall structures includes a clamping device for limiting and holding the adhesive strip.

[0007] The clamping device includes a base and a strip snap-fit ​​part, a strip clamping part, and a clamping support part, which are respectively fixedly disposed on the base; the strip clamping part is disposed between the strip snap-fit ​​part and the clamping support part.

[0008] The adhesive strip snap-fit ​​part is convex in shape, including a protrusion that matches the U-shaped groove of the adhesive strip and a support platform disposed on both sides of the protrusion; the protrusion and the support platform form a support right angle that matches the L-shaped connecting strip of the adhesive strip; the top surface of the protrusion abuts against the bottom surface of the straight support strip of the adhesive strip; the top of the protrusion is provided with a first groove that matches the snap-fit ​​strip of the adhesive strip, and the outer wall of the snap-fit ​​strip of the adhesive strip and the inner wall of the first groove are in friction fit.

[0009] The adhesive strip clamping part includes a first support seat fixedly mounted on the base, a hinge seat fixedly connected to the first support seat, and a pressure plate part hinged to the hinge seat via a connecting rod.

[0010] The pressure plate is L-shaped and includes a horizontal pressure plate that matches the top surface of the straight support strip of the rubber strip and a vertical pressure plate that abuts against the side wall of the L-shaped connecting strip of the rubber strip. The horizontal pressure plate and the vertical pressure plate are integrally formed and connected. The horizontal pressure plate has a cutting reference outer wall along the vertical direction on the side near the connecting rib of the rubber strip. The plane of the cutting reference outer wall coincides with the axis of the semi-circular groove of the rubber strip. Hand-tightening bolts are provided at both ends of the horizontal pressure plate in the length direction. Correspondingly, the protrusion is provided with a nut that matches the hand-tightening bolt.

[0011] The clamping support includes a second support base; when the pressure plate is separated from the adhesive strip, the pressure plate is configured to rest against the top surface of the second support base under the action of gravity.

[0012] Working principle:

[0013] Adhesive strip snap-fit ​​part: The protrusion is embedded in the U-shaped groove of the adhesive strip, and the first groove on the top of the protrusion rubs against the snap-fit ​​strip of the adhesive strip. The support platform and the L-shaped connecting strip of the adhesive strip form a right-angle support, realizing three-dimensional fixation of the bottom of the adhesive strip.

[0014] Pressure plate section: The horizontal pressure plate of the L-shaped pressure plate presses tightly against the top of the rubber strip's straight support strip, while the vertical pressure plate abuts against the side wall of the L-shaped connecting strip. Together with the snap-fit ​​part, they form an upper and lower clamping force to prevent the rubber strip from shifting.

[0015] Cutting reference outer wall: The vertical plane of the edge of the horizontal pressure plate coincides with the axis of the semi-circular groove of the rubber strip, providing a precise cutting reference line for cutting the connecting rib and ensuring accurate cut position.

[0016] Preferably, the protrusion of the adhesive strip snap-fit ​​part is embedded with a sliding nut that matches the hand-tightening bolt. The sliding nut facilitates the matching of connecting rib cutting for adhesive strips of different lengths.

[0017] Preferably, the sliding nut is C-shaped and includes a nut body abutting against the top surface of the protrusion and two sliders disposed below the nut body; correspondingly, the two side walls of the protrusion are provided with sliding grooves that match the sliders; through the slidable engagement between the sliders and the sliding grooves, the position of the sliding nut in the length direction of the protrusion can be adjusted to adapt to the cutting requirements of rubber strip connecting ribs of different lengths.

[0018] Preferably, a connecting wall is provided between the nut body and the slider, and a locking nut that can abut against the side wall of the protrusion is provided on the connecting wall to facilitate the fixing operation of the sliding nut.

[0019] Preferably, the top of the hand-tightening bolt is provided with a six-star plum blossom-shaped handle, which facilitates the limiting and locking of the pressure plate.

[0020] Beneficial effects:

[0021] The Z-shaped adhesive strip clamping device for curtain wall structures provided by this utility model effectively solves the problems of high operational risk, low efficiency, and poor cutting accuracy that exist in the background technology when manually cutting adhesive strip connecting bars through innovative structural design. Specifically, it has the following significant advantages:

[0022] 1. Operational safety and convenience are significantly improved.

[0023] Through the coordinated action of the adhesive strip snap-fit ​​part (protrusion + support platform + first groove) and the adhesive strip clamping part (L-shaped pressure plate + hand-tightening bolt), the adhesive strip is rigidly fixed in all directions in three-dimensional space. The operator does not need to press the adhesive strip by hand, completely avoiding the risk of cuts from tools and greatly reducing operational safety hazards.

[0024] 2. Fundamental improvement in cutting accuracy and consistency

[0025] (1) Innovative cutting reference outer wall design: The vertical plane of the edge of the horizontal pressure plate is strictly aligned with the center line of the semi-circular groove of the rubber strip, forming a physical cutting guide surface. The operator can directly cut along this plane to ensure accurate cut position and one-time forming, completely solving the problems of cut deviation and groove damage caused by manual visual cutting.

[0026] (2) The rubber strip achieves pre-positioning through the frictional cooperation between the protrusion and the first groove and the right-angle limit of the support, and then forms an upper and lower clamping cooperation with the L-shaped pressure plate to achieve zero displacement during the cutting process and prevent the deformation of the cut caused by the shaking of the rubber strip.

[0027] 3. Optimization of universal adaptability and adjustment efficiency

[0028] (1) The sliding nut mechanism (C-shaped nut + slider / groove) supports free adjustment along the length of the protrusion and can be quickly fixed by locking nut. It can flexibly adapt to the cutting requirements of connecting ribs of different lengths of rubber strips, significantly improving the applicability of the equipment.

[0029] (2) The hand-tightening bolt uses a six-star plum blossom-shaped handle, which can lock / release the pressure plate without tools, shortening the operation time.

[0030] 4. Improved production efficiency

[0031] (1) The integrated design of adhesive strip clamping, fixing, cutting and taking out significantly reduces the operation time of a single piece compared with manual cutting.

[0032] (2) Precise mechanical positioning replaces reliance on manual experience, allowing inexperienced operators to quickly master standardized operations and lower the threshold for operation. Attached Figure Description
