Description

Technical Field

[0001] This application relates to the field of unitized curtain wall technology, specifically to a hook connection structure and an internal auxiliary fixing tool for unitized curtain walls. Background Technology

[0002] Unitized curtain walls are building curtain walls in which panels and supporting frames (beams and columns) are manufactured as complete basic curtain wall structural units in the factory and then directly installed on the main structure.

[0003] To facilitate the installation and adjustment of unitized curtain walls, a connection structure is usually installed on them. For example, the installation and connection device for unitized curtain walls disclosed in Chinese patent document CN216075746U includes a first unit hanger and a second unit hanger. The second unit hanger is fixed to the aluminum alloy column of the unitized curtain wall panel. The first unit hanger and the second unit hanger are fixedly connected by fasteners. The first unit hanger is hung on a bracket connector, and the bracket connector is fixed to the main building structure by fasteners. In this structure, on the one hand, the connection of multiple unit hangers makes the hanger structure complex, and the nuts at the connection points are prone to loosening, reducing stability and thus reducing the stability of the unitized curtain wall hanger connection; on the other hand, the second unit hanger adopts the traditional connection method in this technical field, namely bolt + nut, to fasten to the column. This not only has the problem of nuts being prone to loosening, but also requires, during the actual installation, a larger diameter process hole 101 needs to be made on the support frame at the position corresponding to the bolt hole (the diameter of the process hole 101 needs to be larger than the diameter of the bolt nut or the maximum diameter of the fastening part of the fastening tool, see reference) in order to place the bolt and the bolt fastening tool into the tube of the support frame. Figure 1 This reduces the load-bearing capacity of the column 10, thereby reducing the connection stability of the unitized curtain wall. Utility Model Content

[0004] Therefore, this application provides a hook connection structure and an internal auxiliary fixing tool for unitized curtain walls to solve the technical problems of complex hook connection structures and reduced connection stability of unitized curtain walls in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A hook connection structure for a unitized curtain wall includes a hook body, a first fastening plate, and a second fastening plate. The hook body is integrally formed and includes a first hanging plate portion, a second hanging plate portion disposed on one side of the first hanging plate portion, and a hook portion disposed on the first hanging plate portion in an extension direction away from the panel. The first hanging plate portion and the second hanging plate portion are respectively disposed on adjacent outer surfaces of a column. The first fastening plate and the first hanging plate portion are correspondingly disposed on the inner surface of the column, and the second fastening plate and the second hanging plate portion are correspondingly disposed on the other inner surface of the column. A plurality of first connectors connect the first hanging plate portion and the first fastening plate, and a plurality of second connectors connect the second hanging plate portion and the second fastening plate.

[0009] Optionally, both the first and second connectors are flange stainless steel bolts.

[0010] An internal auxiliary fixing tool is used to assist in the installation of the hook connection structure of a unitized curtain wall as described above. It includes a clamping component and a handle component. The clamping component includes a first clamping arm and a second clamping arm that can be opened and closed. The handle component includes a first connecting rod and a second connecting rod connected by a pivot. The first connecting rod is connected to one end of the first clamping arm, and the second connecting rod is connected to one end of the second clamping arm. The handle component is used to drive the opening and closing of the first clamping arm and the second clamping arm.

[0011] The first clamping arm is provided with a first clamping head at the end away from the first connecting rod, and the second clamping arm is provided with a second clamping head at the end away from the second connecting rod. The first clamping head and the second clamping head are used to clamp the first fastening plate or the second fastening plate.

[0012] Optionally, corresponding teeth are provided on the opposing surfaces of the first clamping head and the second clamping head.

[0013] Alternatively, both the first clamping head and the second clamping head have a convex arc segment at the end away from the handle, and the two convex arc segments form an arc-shaped clamping space.

[0014] Alternatively, an auxiliary clamping section may be provided at the end of the convex arc segment away from the handle.

[0015] Optionally, a scale is provided on the front side of the first or second clamping arm.

[0016] Compared with the prior art, this application has at least the following beneficial effects:

[0017] This application discloses a hook connection structure for a unitized curtain wall. Firstly, the hook body is integrally molded. The first mounting plate and the first fastening plate of the hook body correspond and are connected to the inner and outer sides of one side of the column via multiple first connectors. The second mounting plate and the second fastening plate of the hook body correspond and are connected to the inner and outer sides of the other side of the column via multiple second connectors, thus forming a secure connection with the column. The hook body no longer requires complex structural connections, thereby improving the stability of the hook connection in the unitized curtain wall. Secondly, the first fastening plate strengthens the connection stability of the first mounting plate, and the second fastening plate strengthens the connection stability of the second mounting plate. Compared with traditional connection methods, this replaces the nut connection, solving the problem of nuts easily loosening. Furthermore, it eliminates the need to drill additional process holes for bolts and nuts on the column, thereby increasing the load-bearing capacity of the column and achieving the effect of improved connection stability in the unitized curtain wall.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] refer to Figure 2-5 As shown, Embodiment 1 provides a hook connection structure for a unitized curtain wall. The unitized curtain wall includes a panel 9 and a supporting frame. The supporting frame is a rectangular frame formed by upper and lower horizontal beams and left and right columns 10. The panel 9 is disposed within the supporting frame, as shown below. Figure 2 As shown, the connection structure of the unitized curtain wall is located behind the panel 9, and at least two are symmetrically arranged, respectively on the left and right columns 10. The left and right columns 10 are hollow tube structures, with the inside of the hollow tube corresponding to the inner side of the column 10 and the outside of the hollow tube corresponding to the outer side of the column 10. For clarity, this embodiment will describe the connection structure of the unitized curtain wall on the right column 10 in detail.

[0031] The hook connection structure of the unitized curtain wall includes a hook body 1, a first fastening plate 2, and a second fastening plate 3. The hook body 1 is an integrally formed structure. The hook body 1 includes a first hanging plate part 11, a second hanging plate part 12, and a hook part 13. The second hanging plate part 12 is located on the right side of the first hanging plate part 11, and the hook part 13 is located in the extension direction of the first hanging plate part 11 away from the panel 9, that is, the hook part 13 is behind the first hanging plate part 11.

[0032] The first hanging plate part 11 and the second hanging plate part 12 are respectively disposed on adjacent outer surfaces of the column 10. Specifically, the first hanging plate part 11 is disposed on the left outer side of the column 10, and the second hanging plate part 12 is disposed on the rear outer side of the column 10. The first fastening plate 2 and the first hanging plate part 11 are respectively disposed on the left inner side of the column 10, and the second fastening plate 3 and the second hanging plate part 12 are respectively disposed on the rear inner side of the column 10. Multiple first connecting pieces 5 connect the first hanging plate part 11 and the first fastening plate 2, and multiple second connecting pieces 6 connect the second hanging plate part 12 and the second fastening plate 3. The first connecting pieces 5 and the second connecting pieces 6 are preferably flange stainless steel bolts. That is, the first fastening plate 2 is provided with a first threaded hole, and the bolt end of the flange stainless steel bolt (first connecting piece 5) passes through the first hanging plate part 11 and the left side of the column 10 and is threadedly connected to the first threaded hole. Finally, the first hanging plate part 11 and the first fastening plate 2 are fastened to the left side of the column 10 through multiple first connecting pieces 5. The second fastening plate 3 is provided with a second threaded hole, and the bolt end of the flange stainless steel bolt (second connecting piece 6) is threadedly connected to the second threaded hole, so that the second hanging plate part 12 and the second fastening plate 3 are fastened to the rear side of the column 10 through multiple second connecting pieces 6.

[0033] At least two of each of the first connector 5 and the second connector 6 are provided to reduce the probability of the first fastening plate 2 and the second fastening plate 3 becoming loose.

[0034] The installation of the first fastening plate 2 and the second fastening plate 3 requires the use of an auxiliary fixing tool inside the pipe to insert it into the pipe from one end of the column 10, and then fix it with stainless steel flange bolts. After fixing, the auxiliary fixing tool inside the pipe is pulled out. Compared with the traditional nut connection, it is no longer necessary to drill process holes 101 on the side of the column 10, which improves the load-bearing capacity of the column 10.

[0035] The hook part 13 is provided with a hook groove 14 and a lifting hole 15. The opening of the hook groove 14 faces downward, and the lifting hole 15 is provided on the upper part of the hook part 13, and the lifting hole 15 is provided with threads.

[0036] The hook body 1 also includes an adjustment part 16 disposed on the front side of the hook part 13. The adjustment part 16 is disposed on the upper side of the hook groove 14, and an adjustment bolt 4 that can be adjusted up and down is disposed inside the adjustment part 16.

[0037] In this embodiment, the hook connection structure of the unitized curtain wall mainly serves two purposes. First, when the unitized curtain wall is hoisted, the hoisting equipment needs to be connected to the hoisting hole 15. Second, after the hook 13 is hung on the main structure 100 of the building, the adjusting bolt 4 can be adjusted to fine-tune and fix the vertical distance of the unitized curtain wall. After the hoisting equipment is removed, movable bolts can be inserted into the hoisting hole 15 to assist in fixing the unitized curtain wall in the left and right directions.

[0038] In one embodiment, the flange stainless steel bolts can also be threaded through from the inner side of the column 10 to the outer side and connected to the hook body 1. In this case, the first fastening plate 2 and the second fastening plate 3 are no longer needed. The flange stainless steel bolts need to be inserted into the pipe from one end of the column 10 for installation using an auxiliary fixing tool inside the pipe.

[0039] Example 2

[0040] refer to Figure 6 , Figure 7 As shown, Embodiment 2 provides an in-tube auxiliary fixing tool for assisting in the installation of a hook connection structure for a unitized curtain wall described in Embodiment 1. The in-tube auxiliary fixing tool includes a clamping component 7 and a handle component 8. The clamping component 7 includes a first clamping arm 71 and a second clamping arm 72 that can be opened and closed. The handle component 8 includes a first connecting rod 81 and a second connecting rod 82 connected by a pivot. The first connecting rod 81 is connected to one end of the first clamping arm 71, and the second connecting rod 82 is connected to one end of the second clamping arm 72. The handle component 8 is used to drive the opening and closing of the first clamping arm 71 and the second clamping arm 72. The handle component 8 is shaped similarly to scissors.

[0041] The first clamping arm 71 is provided with a first clamping head at the end away from the first connecting rod 81, and the second clamping arm 72 is provided with a second clamping head at the end away from the second connecting rod 82. The first clamping head and the second clamping head are used to clamp the first fastening plate 2 or the second fastening plate 3.

[0042] Taking the clamping of the first fastening plate 2 as an example, in specific application, the handle 8 is opened, causing the first clamping arm 71 and the second clamping arm 72 to open at a certain angle, so that the first clamping head and the second clamping head act simultaneously on the first fastening plate 2 and clamp it. The first fastening plate 2 is placed inside the column 10, corresponding to the first hanging plate part 11. Then, the first hanging plate part 11 and the first fastening plate 2 are fixed with flange stainless steel bolts until the first fastening plate 2 is fully installed. After that, the auxiliary fixing tool inside the pipe is removed from the column 10. By using the auxiliary fixing tool inside the pipe to transport and fix the first fastening plate 2 from one end of the column 10, it is no longer necessary to drill additional holes in the column 10.

[0043] The first clamping head and the second clamping head have corresponding teeth on their opposing surfaces to prevent the first fastening plate 2 from sliding during clamping.

[0044] Both the first clamping head and the second clamping head have a convex arc section 73 at the end away from the handle 8. The two convex arc sections 73 form an arc-shaped clamping space. The convex arc section 73 can also be used to feed bolts into the pipe.

[0045] An auxiliary clamping section 74 is provided at the end of the convex arc segment 73 away from the handle member 8. For example, when the first fastening plate 2 is clamped, the end of the first fastening plate 2 is stuck in the position of the convex arc segment 73. The auxiliary clamping section 74 can increase the clamping area with the first fastening plate 2, thereby improving the stability of the first fastening plate 2 being clamped.

[0046] The front side of the first clamping arm 71 or the second clamping arm 72 is provided with a scale to facilitate determining the distance at which the first fastening plate 2 or the second fastening plate 3 is inserted into the column 10.

[0047] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
