[0002] Cantilever curtain wall is a design and construction technology for the exterior facade of a building. It usually refers to a curtain wall system that protrudes beyond the main structure of the building. Cantilever curtain walls are usually fixed by independent supporting structures, such as alloy keel steel frames. When installing the keel frame of the cantilever curtain wall, it is necessary to use a tower crane to lift it to the rough installation position, and then directly weld the curtain wall keel to the connecting body according to the layout position. Since the keel is prone to shaking during hoisting, the keel swings relative to the layout position, causing a certain deviation when the keel is welded. When the deviation accumulates too much, the installation quality of the curtain wall is difficult to guarantee.

[0003] In order to solve the above problems, a positioning device is needed, which can provide effective positioning during the keel welding process and is easy to use and remove. Utility Model Content

[0018] It should be noted that, in the description of this specification, the terms "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. The outer side in this embodiment is the side away from the preset position, and the inner side is the side close to the preset position; the preset position in this embodiment refers to the cantilevered steel beam on which the keel is to be installed. The positioning in this embodiment is to limit the lateral swing of the keel, but not to limit the adjustment of its elevation, which can be understood by technicians in this technical field and will not be elaborated here.

[0019] As shown in the figure, the utility model discloses a positioning device for installing a cantilever curtain wall keel, including a positioning back plate 1, a positioning panel 2 and a connecting rod 3. The positioning back plate 1 and the positioning panel 2 form a detachable connection through the connecting rod 3. The positioning back plate 1 and the positioning panel 2 can be driven close to each other to clamp the set position 6; the positioning panel 2 is provided with a limiting portion. The positioning back plate 1 and the positioning panel 2 are driven close to each other, and then after being locked, they can be clamped and fixed at the set position 6, so that the positioning of the limiting portion at the set position 6 is determined, and then the keel is positioned by the limiting portion, so that the positioning of the keel at the set position 6 is achieved.

[0020] In this embodiment, the positioning panel 2 includes a fixed plate and a movable plate, and the movable plate is hinged to the fixed plate and forms a limiting portion. In this embodiment, the movable plate includes a first movable base plate 201, a second movable base plate 202 and a third movable base plate 203, and the first movable base plate 201, the second movable base plate 202 and the third movable base plate 203 are connected in sequence, and the fixed plate includes a first fixed base plate 204 and a second fixed base plate 205, and the third movable base plate 203 is hinged to the first fixed base plate 204 through a hinge 206, and the second movable base plate 202, the third movable base plate 203 and the first fixed base plate 204 constitute the limiting portion. In this embodiment, the limiting portion is a rectangular frame structure with a single-side opening, and the limiting portion is located on the outer side of the first movable base plate 201, and the limiting portion opening faces inward. In this embodiment, the positioning panel 2 is in the shape of a "convex" as shown in the figure. The positioning panel 2 is a split structure. The fixed plate cooperates with the positioning back plate 1 to realize the initial positioning of the entire device at the preset position, and the movable plate is hinged, which forms a movable limit part similar to a door. When positioning the keel, the movable plate is first swung to open the limit part, and the keel is placed and attached to the fixed first fixed base plate 204, and then the movable plate is swung to close the limit part, so that the second movable base plate 202 and the third movable base plate 203 are attached to the keel, and then the three sides of the limit part are attached to the surface of the keel, so as to realize the positioning of the keel and prevent it from swinging during welding, and at the same time, it does not affect the adjustment of the elevation of the keel. The overall operation is convenient and fast.

[0021] In this embodiment, a positioning block 4 is also included, and the positioning block 4 is sleeved on the connecting rod 3. As shown in the figure, the positioning block 4 in this embodiment is a cubic structure made of square steel, and the positioning block 4 is sleeved on the connecting rod 3. In this embodiment, two positioning blocks 4 are set for each connecting rod 3, and the two positioning blocks 4 on each connecting rod 3 are respectively correspondingly connected to the positioning panel 2 or the positioning back plate 1. As shown in the figure, the positioning back plate 1 is provided with two positioning blocks 4, and the first movable base plate 201 and the second fixed base plate 205 are respectively provided with one. When in use, the surface of the positioning block 4 is fitted on the top surface of the preset position, which plays a positioning role for the entire positioning device in the vertical direction, and also avoids the connecting rod 3 from directly contacting the set position 6. The connecting rod 3 is connected to the positioning panel 2 (i.e., the first movable base plate 201 and the second fixed base plate 205) or the positioning back plate 1 after passing through the positioning blocks 4 respectively.

[0022] In this embodiment, a locking member 5 is also included. The two ends of the connecting rod 3 are respectively correspondingly penetrated through the positioning back plate 1 and the positioning panel 2. The locking member 5 is arranged at the end of the connecting rod 3 to lock and limit the positioning back plate 1 and the positioning panel 2. In this embodiment, the first movable base plate 201 and the second fixed base plate 205 are respectively connected to the positioning back plate 1 through the connecting rod 3. As shown in the figure, the locking member 5 in this embodiment is a nut, and the connecting rod 3 is a screw rod. After the end of the connecting rod 3 passes through the positioning back plate 1, the first movable base plate 201 or the second fixed base plate 205, it is locked and limited by the locking member 5. The rotation of the locking member 5 can make the positioning back plate 1 and the positioning panel 2 approach each other and form a clamping limit. The locking member 5 can also be a component with a locking and limiting function such as a buckle or a latch. This is understandable to technicians in this technical field and will not be repeated here. At the same time, in this embodiment, in order to facilitate the swinging of the movable plate, avoidance holes, avoidance grooves and other structures can be set on the first movable base plate 201 and its corresponding positioning block 4 to facilitate the movable plate to be sleeved on the connecting rod 3. This is understandable to those skilled in the art and will not be elaborated here.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
