Description

Technical Field

[0001] This utility model relates to the field of curtain wall construction technology, specifically to a ground welding auxiliary device for curtain wall keel. Background Technology

[0002] During the construction of curtain walls, the welding of the keel is a crucial step that directly affects the structural strength and overall aesthetics of the curtain wall.

[0003] In traditional construction practices, such as Figure 1 The welding of the inclined beam curtain wall keel shown is usually carried out at height, with workers using scaffolding or cranes to complete the welding in the air. However, high-altitude welding is limited by the working space, making it inconvenient for workers to operate and difficult to guarantee the quality of each weld. In addition, high-altitude welding is less efficient, as workers often need to rely on cranes or scaffolding for positioning and movement, which slows down the construction progress.

[0004] To address the various challenges of high-altitude welding, some construction companies have recently begun to experiment with moving the welding of some inclined beam keels to the ground, where the welding is completed. Figure 2 The unitized inclined beam curtain wall keel is then hoisted and welded onto the inclined beam to reduce high-altitude operations.

[0005] However, while the building frame can serve as a measurement benchmark in high-altitude welding, helping workers position and align welding components, this is lacking in ground welding. Workers require significantly more time to measure, align, and adjust the position of the keel, which is not only time-consuming but also prone to errors, resulting in poor overall control and accumulated errors that can cause overall deviations in the curtain wall. Therefore, the quality and efficiency of ground welding are difficult to guarantee.

[0006] The welding of the keel in curtain wall construction involves a large amount of work, so the welding quality and speed need to be given special attention. Measures need to be taken to ensure the welding quality and speed of the keel, so as to guarantee the progress and quality of the project and deliver the project smoothly.

[0007] Therefore, it is necessary to study an auxiliary device for welding the ground of curtain wall keel. Utility Model Content

[0008] Therefore, the purpose of this utility model is to provide an auxiliary device for ground welding of curtain wall keel, which can effectively solve the problems of cumbersome size positioning and difficulty in ensuring welding quality and efficiency when welding unitized inclined beam curtain wall keels on the ground.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A ground welding auxiliary device for curtain wall keel includes a placement frame, front and rear positioning columns, left and right positioning columns, and a calibration frame;

[0011] The placement rack includes a horizontal frame, two vertical frames perpendicularly connected to the horizontal frame, and a connecting frame;

[0012] Several calibration frames are vertically connected to the middle of the cross frame, and the calibration frames are distributed between the two longitudinal frames.

[0013] The upper surfaces of the horizontal frame, vertical frame, and calibration frame are on the same plane and form a keel placement surface;

[0014] Multiple front and rear positioning posts are fixed at intervals on the cross frame;

[0015] Multiple left and right positioning columns are fixedly connected at intervals on both longitudinal frames.

[0016] The connecting frame is located at one end of the two longitudinal frames away from the transverse frame.

[0017] Furthermore, a seat frame is fixedly connected to the connecting frame.

[0018] Furthermore, the two ends of the longitudinal frame are adjustable in the left and right directions relative to the transverse frame and the connecting frame, respectively, and the calibration frame is adjustable in the left and right directions on the transverse frame.

[0019] Furthermore, a sliding groove is provided on the opposite side of the cross frame and the connecting frame, and a first sliding block is fixedly connected to both the front and rear ends of the longitudinal frame. The first sliding block is slidably disposed in the sliding groove and fixed in position by the second connecting member.

[0020] Furthermore, a second slide block is fixed to the end of the calibration frame. The second slide block is slidably disposed in the slide groove of the cross frame and fixed in position by the second connector.

[0021] Furthermore, both the cross frame and the connecting frame are provided with strip-shaped holes in the left and right directions that are adapted to the first connecting member. The first connecting member passes through the strip-shaped holes to detachably connect the corresponding first slide block to the cross frame or the connecting frame.

[0022] Furthermore, left and right positioning posts are fixed at intervals at both ends of the longitudinal frame, and the upper ends of the left and right positioning posts extend upward to form a keel placement surface.

[0023] Furthermore, the front and rear positioning posts are both fixed to the front end face of the cross frame, and the upper ends of the front and rear positioning posts extend upward to form a keel placement surface.

[0024] Furthermore, the lower part of the placement rack is vertically fixedly connected to multiple support legs.

[0025] The beneficial effects of the above technical solution are:

[0026] (1) The keel structure of the inclined beam curtain wall targeted by this utility model uses horizontal frames, vertical frames and calibration frames to form a keel placement surface for placing various components of the keel. Multiple front and rear positioning columns are fixed at intervals on the horizontal frames for quickly positioning the front and rear directions of the horizontal keel. Multiple left and right positioning columns are fixed at intervals on both vertical frames for quickly positioning the left and right positions of the vertical keel, improving the positioning efficiency when welding the vertical keel and the horizontal keel. A calibration frame is vertically connected in the middle of the horizontal frame. By placing the web members on the calibration frame and aligning them with the calibration frame, the position of the web members can be quickly positioned, improving the positioning efficiency when welding the web members and the horizontal keel. Thus, it can effectively solve the problem of cumbersome size positioning and difficulty in ensuring welding quality and efficiency when welding unitized inclined beam curtain wall keels on the ground, simplifying the size positioning process and improving the efficiency and quality when welding keels on the ground.

[0027] (2) A seat frame is fixedly connected to the connecting frame of this utility model for welding workers to sit on, so that workers can sit on the seat frame to carry out continuous welding work during the welding process, avoiding fatigue caused by long-term squatting.

The calibration frame is adjustable in the left and right directions and is set on the transverse frame to adapt to curtain wall keels of different sizes. Based on the fast and accurate positioning, it can improve applicability. Attached Figure Description

Detailed Implementation

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0040] Example 1: This example aims to provide a ground welding auxiliary device for curtain wall keel, which is mainly used for welding inclined beam curtain wall keels. It addresses the problems of cumbersome size positioning and difficulty in ensuring welding quality and efficiency when welding unitized inclined beam curtain wall keels on the ground.

[0041] like Figure 2 The unitized inclined beam curtain wall keel 5 includes a horizontal keel 501, longitudinal keels 502 vertically welded to the left and right ends of the horizontal keel 501, and web members 503 welded at intervals to the horizontal keel 501. The web members 503 are located between the two longitudinal keels 502.

[0042] A curtain wall keel ground welding auxiliary device, such as Figure 3 and Figure 4 It includes a placement frame 1, front and rear positioning posts 2, left and right positioning posts 3, and a calibration frame 4.

[0043] like Figure 3 and Figure 4 The placement rack 1 includes a horizontal frame 101 and vertical frames 102 welded to the left and right ends of the horizontal frame 101. The horizontal frame 101 is made of 750*50*5 hot-dip galvanized square tubing, and the vertical frames 102 are made of 600*50*5 hot-dip galvanized square tubing. A connecting frame 103 is welded and fixed to the two vertical frames 102 at the end away from the horizontal frame 101, so that the placement rack 1 forms a rectangular frame structure.

[0044] Two calibration frames 4 are vertically welded in the middle of the cross frame 101. The calibration frames 4 are 250*50*5 hot-dip galvanized square tubes and are distributed between the two longitudinal frames 102.

[0045] In this embodiment, for example, Figure 2 The dimensions of the unitized inclined beam curtain wall keel 5, the horizontal frame 101, the vertical frame 102 and the calibration frame 4 are all corresponding to the dimensions of the unitized inclined beam curtain wall keel 5, so that when welding the keel structure, the positioning can be quick and accurate, and the construction efficiency is high.

[0046] The upper surfaces of the horizontal frame 101, the vertical frame 102, and the calibration frame 4 are on the same plane and form a keel placement surface for placing items such as... Figure 2 The unitized inclined beam curtain wall keel 5 is shown. Two vertical front and rear positioning columns 2 are welded at intervals on the rear end face of the horizontal frame 101. The front and rear positioning columns 2 are fixed to the front end face of the horizontal frame 101. The upper ends of the front and rear positioning columns 2 extend upward to the keel placement surface, so as to facilitate the quick positioning of the horizontal keel 501 in the front and rear direction. Combined with the one-to-one size relationship between the horizontal keel 501 and the horizontal frame 101, the quick positioning of the horizontal keel 501 is achieved.

[0047] Two sets of vertical left and right positioning columns 3 are welded to the left and right sides of the two longitudinal frames 102 at intervals. The upper ends of the left and right positioning columns 3 of the keel extend to the keel placement surface, so as to quickly position the left and right positions of the longitudinal keel. Combined with the one-to-one size relationship between the longitudinal keel 502 and the longitudinal frame 102, the longitudinal keel 502 can be quickly positioned.

[0048] Two calibration frames are vertically welded to the middle of the cross frame. By placing the web member 503 on the calibration frame 4 according to a one-to-one size and positional relationship and aligning it with the calibration frame 4, the position of the web member 503 can be quickly located, improving the positioning efficiency when welding the web member 503 to the cross keel 501.

[0049] In this embodiment, the horizontal keel 501 is first placed on the horizontal frame 101 and positioned using the front and rear positioning posts 2 and the dimensional ratio. Then, the two vertical keels 502 are placed on the two vertical frames 102 respectively, and their positions are marked using the left and right positioning posts 3 and the dimensional ratio. After marking, the vertical keels 502 and the horizontal keel 501 are welded together. Finally, the web member 503 is placed on the marking post and its position is marked using the dimensional ratio. Finally, the web member 503 and the horizontal keel 501 are welded together, completing the ground welding of the unitized inclined beam curtain wall keel 5.

[0050] like Figure 3 and Figure 4 A connecting frame 103 is welded between the two longitudinal frames 102. A seat frame 8 is welded to the connecting frame 103. The seat frame 8 is a platform formed by welding 250*50*5 hot-dip galvanized square tubes. It is located on the side away from the keel placement surface, so that workers can sit on the seat frame 8 to carry out continuous welding work during the welding process, avoiding fatigue caused by long-term squatting. It is suitable for continuous welding work with a large workload.

[0051] A support leg 11 is vertically welded to the lower corner of the placement frame 1 to support this welding auxiliary device.

[0052] Example 2: This example optimizes the placement rack 1 so that the vertical rack 102 and the calibration rack 4 can be adjusted in the left and right directions, thereby improving applicability while ensuring fast and accurate positioning.

[0053] In this embodiment, as Figure 5 , Figure 6 and Figure 8 The front and rear ends of the longitudinal frame 102 are slidably disposed between the transverse frame 101 and the connecting frame 103, respectively, and are fixed in position by the first connecting member 10. A sliding groove 104 is provided on the opposite side of the transverse frame 101 and the connecting frame 103. Specifically, in this embodiment, both the transverse frame 101 and the connecting frame are made of U-shaped channel steel, and the sliding groove 104 is a through groove of the U-shaped channel steel. The sliding grooves 104 of the transverse frame 101 and the connecting frame 103 face each other. A first sliding block 9 is fixedly connected to both the front and rear ends of the longitudinal frame 102. The first sliding block 9 is slidably disposed in the sliding groove 104. The first sliding block 9 can be a channel steel or a square steel. A first connecting member 10 passes through the first sliding block 9. A left-right strip hole 105 adapted to the first connecting member 10 is provided on both the transverse frame 101 and the connecting frame 103. The first connecting member 10 passes through the strip hole 105 to detachably connect the corresponding first sliding block 9 to the transverse frame 101 or the connecting frame 103. The first slide block 9 can be adjusted to the left and right position along the slide groove 104. The adjustment range is the length range of the strip hole 105, so as to adjust the left and right position of the longitudinal frame 102 and adapt to curtain wall keel 5 of different widths.

[0054] The calibration frame 4 is slidably mounted on the crossbeam 101 and fixed in position by the second connector. A second slide block 12 is welded to the end of the calibration frame 4. The second slide block 12 is slidably mounted in the slide groove 104 of the crossbeam 101. The second slide block 12 has the same structure as the first slide block 9. The second connector is the same as the first connector 10, and the principle of fixing the position is the same as that of the first connector 10. Position fixing and detachable connection are achieved by providing a strip-shaped hole and inserting the second connector. Its specific structure and working principle will not be elaborated here. In other embodiments, if the curtain wall keel 5 includes two or more web members 503, the calibration frame 4 can be additionally installed.

[0055] In this embodiment, since the one-to-one size ratio is no longer followed as in Embodiment 1, the positioning mainly relies on one side. Before use, the longitudinal frame 102 and the calibration frame 4 are adjusted in position. Taking a welded curtain wall keel 5 as a reference, the longitudinal frame 102 is aligned with one side of the longitudinal keel 502, and the calibration frame 4 is aligned with one side of the web member 503. During use, when aligning and welding the curtain wall keel 5, first place the horizontal keel 501 on the horizontal frame 101 and position it front and back using the front and rear positioning posts 2. Then place a vertical keel 502 on one of the vertical frames 102 and position it left and right using the left and right positioning posts 3. The end of the vertical keel 502 abuts against the horizontal keel 501 to position it front and back. The end of the horizontal keel 501 is flush with the side of the vertical keel 502 away from the keel placement area to position it left and right. Then weld the horizontal keel 501 and the vertical keel 502. Next, align and weld another vertical keel 502. Finally, place the web member 503 on the calibration frame 4 and align it with one side of the calibration frame 4 to position it left and right. Weld it to the horizontal keel 501 to complete the ground welding of the unitized inclined beam curtain wall keel 5.
