Description

Technical Field

[0001] The present invention relates to a curtain wall installation positioning device, in particular to a curtain wall installation positioning device for complex nodes applied in the field of curtain wall installation technology. Background Art

[0002] Curtain wall is the outer wall of a building. Because it does not bear weight itself, it is hung on the outer surface of the building like a curtain. It is a lightweight wall with decorative effect commonly found in modern large-scale high-rise buildings. It has reached a new level in beauty, color, durability, flatness and shape.

[0003] The specification of Chinese patent CN115522752B discloses "A curtain wall clamping rapid positioning assembly device and assembly method", in which a spring is arranged between the bolt and the fixing device. Under the elastic jacking of the spring, the bolt and the fixing device threads are more closely fitted, and the friction between the threads is increased after fitting, thereby ensuring the fixation between the fixing device and the bolt and reducing the movement of the bolt. The magnetic repulsion between the first magnetic block and the second magnetic block. The specification of Chinese patent CN117127743B discloses "A heavy-duty imitation stone concrete hanging panel installation method", in which the expanded blades used are windmill-shaped, which increases the contact area and avoids the tearing of the concrete hanging panel caused by stress concentration. The number of connection nodes between the mounting plate and the horizontal steel frame gradually decreases from bottom to top, which can avoid the occurrence of inverted eight-shaped tearing cracks at the upper node. A positioning unit is also provided, and the concrete hanging panel is lifted and hung on the positioning unit, which is convenient for later movement of the concrete hanging panel.

[0004] During curtain wall installation, the curtain wall panels need to be installed and fixed according to the division of the keel bracket, and the keel bracket mostly adopts a combination of horizontal steel frames and vertical steel frames. Therefore, the fixed node positions of the curtain wall panels are mostly at their four corners. However, there are often some special situations on the exterior walls of buildings. For example, there are pre-buried wires, water pipes or gas pipes in the wall. The original assembly node positions cannot be used. The existing technology cannot solve the node offset problem caused by the pre-buried pipelines in the wall, which in turn affects the positioning and installation operation of the curtain wall. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that some special situations often occur in the exterior walls of buildings, and the original assembly node positions cannot be used, which affects the selection of positioning and installation nodes, and further affects the positioning and installation operations of the curtain wall.

[0006] To solve the above problems, the present invention provides a positioning device for installing a curtain wall for complex nodes, comprising a keel grid bracket fixedly mounted on a building wall and a positioning pile, the positioning pile being located in the middle of the keel grid bracket, a curtain wall hanging plate being provided on the outside of the keel grid bracket, and bolt rods being rotatably connected to both ends of the top of the keel grid bracket, and hanging plate brackets being fixedly connected to both ends of the bottom of the keel grid bracket, threaded sleeves being fixedly embedded at both ends of the top of the curtain wall hanging plate, the threaded sleeves being threadedly connected to the bolt rods, and hanging holes being provided at both ends of the bottom of the curtain wall hanging plate, which are plugged into the hanging plate brackets;

[0007] The outer end of the positioning pile is rotatably connected to multiple groups of node positioning brackets. A positioning hole is opened at the end of the node positioning bracket away from the positioning pile. An expansion screw is inserted into the inside of the positioning hole. The sleeve end of the expansion screw is fixedly embedded in the building wall. The screw end of the expansion screw is fixedly connected to the No. 1 positioning rod. The surface of the end of the curtain wall hanging panel facing the keel grid bracket is fixedly connected to the No. 1 ring track ring. The inside of the No. 1 ring track ring is slidably connected to the No. 1 combination block. The hollow of the No. 1 combination block is opened with a combination hole, and the combination hole is inserted into the No. 1 positioning rod.

[0008] In the positioning device for curtain wall installation with complex nodes mentioned above, the node positioning bracket is rotated with the positioning pile as the center of the circle, and a position suitable for installing the expansion screw is selected on the building wall to solve the difficulty in node selection caused by the complex situation of the building wall. Subsequently, the No. 1 positioning rod and the combination hole on the No. 1 combination block are used for positioning and plugging, which effectively improves the positioning and installation operation of the building wall.

[0009] As a further improvement of the present invention, the radius of the No. 1 ring track ring corresponds to the length of the node positioning bracket, and the center of the No. 1 ring track ring corresponds to the positioning placement pile, so that the position of the expansion screw selected by the point positioning bracket corresponds to the annular area of ​​the No. 1 ring track ring, which facilitates the No. 1 positioning rod to be accurately inserted into the combination hole on the No. 1 combination block.

[0010] As a further improvement of the present invention, a clamping block is telescopically provided on the surface of the No. 1 positioning rod, and an annular groove is provided on the inner wall of the combination hole. The clamping block is clamped into the annular groove and corresponds to the annular groove, and the outer end of the clamping block is arranged in an arc shape. The clamping block and the annular groove are clamped into each other, which effectively improves the stability of the connection between the No. 1 positioning rod and the combination hole.

[0011] As a further improvement of the present invention, the middle part of the node positioning bracket is slidably connected to a positioning slider, and the middle part of the positioning slider is fixedly connected to a No. 2 positioning rod. The No. 2 positioning rod has the same structure as the No. 1 positioning rod. The arrangement position of the No. 2 positioning rod is changed by sliding the positioning slider on the node positioning bracket.

[0012] As another improvement of the present invention, the inner ring of the No. 1 track ring is fixedly connected to the No. 2 track ring, and the interior of the No. 2 track ring is slidingly connected to the No. 2 combination block. The No. 2 positioning rod corresponds to the No. 2 combination block, and the No. 2 combination block has the same structure as the No. 1 combination block. The No. 2 positioning rod is assembled with the No. 2 combination block to realize the positioning assembly of the curtain wall hanging panel.

[0013] As another improved supplement to the present invention, a series hole is opened at the bottom of the positioning slider, and a limiting ring is passed through the inside of the series hole. The diameter of the No. 2 ring track ring corresponds to the diameter of the limiting ring. The limiting ring is used to limit the sliding position of each positioning slider, so that each positioning slider is distributed in a ring corresponding to the No. 2 ring track ring.

[0014] As another improved supplement to the present invention, a center positioning column is fixedly connected to the middle of the limiting ring, and a center hole is opened in the middle of the curtain wall panel. The center positioning column is plugged into the center hole. By plugging the center positioning column into the center hole, the center of the limiting ring and the No. 2 ring track ring are calibrated, which makes it easier for each positioning slider to accurately correspond to the annular area of ​​the No. 2 ring track ring.

[0015] To sum up, the present invention fixes the positioning piles in the middle area of ​​the keel grid bracket, and then the node positioning bracket rotates with the positioning piles as the center of the circle, and selects a suitable installation node on the building wall in the middle area of ​​the keel grid bracket, that is, the position for installing the expansion screws, so as to solve the node selection difficulties caused by the complexity of the existing building walls, and the selected expansion screw installation nodes are distributed in a ring shape corresponding to the No. 1 ring track ring, providing a basis for the subsequent positioning and plugging of the No. 1 positioning rod and the combination hole on the No. 1 combination block. Through the cooperation of the No. 1 ring track ring and the node positioning bracket, the adaptive positioning of the asymmetric node is realized, which facilitates the positioning and installation operation of the building wall.

[0027] Two embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] The first implementation method:

[0029] Figures 1 to 3 The figure shows a positioning device for installing a curtain wall with a complex node, comprising a keel grid bracket 1 and a positioning pile 2 fixedly mounted on a building wall. The positioning pile 2 is located in the middle of the keel grid bracket 1. A curtain wall hanging plate 101 is provided on the outside of the keel grid bracket 1, and both ends of the top of the keel grid bracket 1 are rotatably connected to a bolt rod 102. Both ends of the bottom of the keel grid bracket 1 are fixedly connected to a hanging plate bracket 103. Both ends of the top of the curtain wall hanging plate 101 are fixedly inlaid with a threaded sleeve 104, which is threadedly connected to the bolt rod 102. Both ends of the bottom of the curtain wall hanging plate 101 are provided with a hanging hole 105, which is plugged into the hanging plate bracket 103.

[0030] The keel grid bracket 1 is fixedly installed on the building wall, and then the curtain wall hanging panel 101 is installed in an orderly manner corresponding to the area division of the keel grid bracket 1, that is, the threaded sleeve 104 on the top of the curtain wall hanging panel 101 corresponds to the bolt rod 102 on the keel grid bracket 1 for threaded connection and fixation, and the hanging hole 105 at the bottom of the curtain wall hanging panel 101 corresponds to the hanging hole 105 on the keel grid bracket 1 for plugging and fixing. The above steps are all installed by the existing curtain wall keel and will not be repeated here.

[0031] Figures 2 to 6 It is shown that the outer end of the positioning pile 2 is rotatably connected to a plurality of groups of node positioning brackets 201, and a positioning hole 202 is provided at one end of the node positioning bracket 201 away from the positioning pile 2, and an expansion screw 203 is inserted into the interior of the positioning hole 202, and the sleeve end of the expansion screw 203 is fixedly embedded in the building wall, and the screw end of the expansion screw 203 is fixedly connected to a No. 1 positioning rod 204, and the surface of the end of the curtain wall hanging panel 101 facing the keel grid bracket 1 is fixedly connected to a No. 1 ring track ring 205, and the interior of the No. 1 ring track ring 205 is slidably connected to a No. 1 combination block 206, and a combination hole 207 is provided in the hollow of the No. 1 combination block 206, and the combination hole 207 is plugged into the No. 1 positioning rod 204, and the radius of the No. 1 ring track ring 205 corresponds to the length of the node positioning bracket 201, and the center of the No. 1 ring track ring 205 is aligned with the positioning rod 204. The placement pile 2 corresponds to the expansion screw 203 selected by the node positioning bracket 201, so that the position of the expansion screw 203 corresponds to the annular area of ​​the No. 1 ring track ring 205, which is convenient for the No. 1 positioning rod 204 to be accurately plugged into the combination hole 207 on the No. 1 combination block 206. The surface of the No. 1 positioning rod 204 is telescopically provided with a clamping block 208, and the interior of the clamping block 208 contains a spring that pushes outward to provide power for the automatic outward pop-up of the clamping block 208, and when the clamping block 208 is squeezed, the spring is compressed to achieve the retraction of the clamping block 208 into the No. 1 positioning rod 204. The inner wall of the combination hole 207 is provided with an annular groove 209, and the clamping block 208 is correspondingly engaged with the annular groove 209, and the outer end of the clamping block 208 is arranged in an arc shape. The clamping block 208 is engaged with the annular groove 209, which effectively improves the plug-in stability of the No. 1 positioning rod 204 and the combination hole 207.

[0032] A positioning pile 2 is fixedly installed in the middle area of ​​the keel grid bracket 1, so that the positioning pile 2 corresponds to the center of the curtain wall hanging panel 101 installed later. The node positioning bracket 201 is rotated with the positioning pile 2 as the center of the circle, and a suitable installation node is selected on the building wall in the middle area of ​​the keel grid bracket 1. The rotation range of the node positioning bracket 201 is determined by the number of its own installations and the angle between two adjacent node positioning brackets 201. Figure 6As shown, this embodiment adopts three node positioning brackets 201, so the rotation range of the node positioning bracket 201 is 120°, and the minimum angle between two adjacent node positioning brackets 201 shall not be less than 90°. The position of installing the expansion screw 203 is determined to avoid setting the installation node in the area where the wall adjustment is not suitable, and solve the node selection difficulty caused by the complex situation of the existing building wall. The selected expansion screw 203 installation node corresponds to the No. 1 ring track ring 205 and is distributed in a ring. When the curtain wall hanging panel 101 is assembled, the No. 1 positioning rod 204 on the expansion screw 203 is in the annular area of ​​the No. 1 ring track ring 205. The sliding position of the No. 1 assembly block 206 in the No. 1 ring track ring 205 is adjusted to realize the positioning and plugging of the No. 1 positioning rod 204 and the combination hole 207 on the No. 1 assembly block 206 to complete the positioning and installation of the curtain wall hanging panel 101. Through the cooperation of the No. 1 ring track ring 205 and the node positioning bracket 201, the adaptive positioning of the asymmetric node is realized, which facilitates the positioning and installation operation of the building wall.

[0033] Second implementation method:

[0034] Compared with the first embodiment, the main new addition is a positioning slider 3, and the No. 1 positioning rod 204 on the expansion screw 203 is not used. Instead, the No. 2 positioning rod 301 is installed on the positioning slider 3. The specific new structure is as follows, and the rest of the structure is consistent with the first embodiment.

[0035] Figures 7 to 9 As shown, the middle part of the node positioning bracket 201 is slidably connected with a positioning slider 3, and the middle part of the positioning slider 3 is fixedly connected with a No. 2 positioning rod 301. The No. 2 positioning rod 301 has the same structure as the No. 1 positioning rod 204. The positioning slider 3 slides on the node positioning bracket 201 to change the arrangement position of the No. 2 positioning rod 301. The inner ring of the No. 1 ring track ring 205 is fixedly connected with the No. 2 ring track ring 302. The interior of the No. 2 ring track ring 302 is slidably connected with the No. 2 assembly block 303. The No. 2 positioning rod 301 corresponds to the No. 2 assembly block 303. The No. 2 assembly block 303 has the same structure as the No. 1 assembly block 206. The No. 2 positioning rod 301 and the No. 2 assembly block 303 are assembled to realize the positioning assembly of the curtain wall hanging panel 101.

[0036] If during the installation process of the positioning pile 2, the original installation position of the positioning pile 2 is not suitable, the positioning pile 2 is installed nearby on the periphery of the original area, the operation node positioning bracket 201 is rotated with the positioning pile 2 as the center, and a suitable installation node is selected on the building wall in the middle area of ​​the keel grid bracket 1. In order to avoid the inconvenience of fixedly installing the expansion screw 203, the No. 1 positioning rod 204 originally installed on the expansion screw 203 is cancelled, and the No. 2 positioning rod 301 is installed on the positioning slider 3 instead. The arrangement position of the No. 2 positioning rod 301 is adjusted to correspond to the No. 2 ring track ring 302, and the No. 2 positioning rod 301 and the No. 2 combination block 303 are assembled to realize the positioning assembly of the curtain wall panel 101, thereby avoiding the positioning assembly operation of the curtain wall panel 101 affected by the change in the installation position of the positioning pile 2.

[0037] Figures 7 to 9 As shown, a serial hole 304 is provided at the bottom of the positioning slider 3, and a limiting ring 305 is passed through the interior of the serial hole 304. The diameter of the No. 2 ring track ring 302 corresponds to the diameter of the limiting ring 305. The limiting ring 305 is used to limit the sliding position of each positioning slider 3, so that each positioning slider 3 is distributed in a ring corresponding to the No. 2 ring track ring 302. A center positioning column 306 is fixedly connected to the middle of the limiting ring 305. A center hole 307 is provided in the middle of the curtain wall hanging plate 101. The center positioning column 306 is plugged into the center hole 307. By plugging the center positioning column 306 into the center hole 307, the center of the limiting ring 305 and the No. 2 ring track ring 302 are calibrated, so that each positioning slider 3 can accurately correspond to the annular area of ​​the No. 2 ring track ring 302.

[0038] When adjusting the sliding position of the positioning slider 3 on the node positioning bracket 201, the limiting ring 305 is used to standardize the position of each positioning slider 3, so that each positioning slider 3 is in a ring-shaped distribution state, and the center positioning column 306 and the center hole 307 are connected to realize the center calibration of the limiting ring 305 and the No. 2 ring track ring 302, so that each positioning slider 3 can accurately correspond to the annular area of ​​the No. 2 ring track ring 302, providing an accurate basis for the assembly of the No. 2 positioning rod 301 and the No. 2 combination block 303.

[0039] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted by the present invention is not limited thereto. Various changes made within the knowledge scope of those skilled in the art without departing from the concept of the present invention still fall within the protection scope of the present invention.
