[0002] With the rapid development of the construction industry, steel structures are increasingly used in building projects. In particular, urban construction, driven by aesthetic requirements, has led to various multi-dimensional and irregular steel structure designs, which has also brought enormous difficulties and challenges to component installation. Especially for components with fixed installation angles, such as truss diagonal braces, current technology requires the use of multiple chain hoists to adjust the installation angle and position each time, making precision control difficult and significantly impacting installation efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a rapid hoisting and positioning device for heavy truss diagonal web members, which effectively solves the technical problem that the installation angle of heavy truss diagonal web members cannot be controlled, affecting the installation accuracy and efficiency, and overcomes the shortcomings of the prior art.

[0004] The technical solution adopted in this utility model is: a rapid hoisting and positioning device for heavy-duty truss diagonal web members, comprising:

[0005] A placement rack is used to place the inclined web members to be installed, so that the inclined web members are placed at an installation angle.

[0006] A hoisting frame is installed above the placement frame for hoisting the diagonal brace. During the hoisting process, the diagonal brace is tilted at the installation angle.

[0007] Furthermore, the placement rack includes a horizontal placement bar, on which multiple vertical placement bars are supported. The multiple vertical placement bars form a placement slope, and the inclination angle of the placement slope is the same as the installation angle.

[0008] Furthermore, a placement reinforcement rod is provided between the plurality of longitudinal placement rods.

[0009] Furthermore, the horizontal placement bar is provided with a vertical support bar and an oblique support bar, and the ends of the vertical support bar and the oblique support bar away from the horizontal placement bar are arranged crosswise to support the longitudinal placement bar.

[0010] Furthermore, the placement horizontal bar includes a transverse horizontal bar and a longitudinal horizontal bar. The ends of the vertical support bar and the diagonal support bar near the placement horizontal bar are disposed on the transverse horizontal bar, and the longitudinal horizontal bar is disposed on the side of the vertical support bar and the diagonal support bar.

[0011] Furthermore, a placement positioning rod is provided on the side of the placement horizontal rod near the lower side of the placement slope.

[0012] Furthermore, the hoisting frame includes a hoisting horizontal bar, on which a fixed-angle lifting rod is provided for hoisting the inclined web member at the installation angle.

[0013] Furthermore, the fixed-angle suspension rod includes a first suspension rod and a second suspension rod, the first suspension rod and the second suspension rod having different lengths, causing the inclined web rod to be tilted at the installation angle.

[0014] Furthermore, a lifting reinforcement rod is provided between the first and second lifting rods.

[0015] The advantages and positive effects of this utility model are as follows: Due to the adoption of the above technical solution, after the truss diagonal web members are transported to the construction site, they can be directly unloaded onto the placement frame. The placement angle of the placement frame is consistent with the installation angle of the diagonal web members, avoiding multiple subsequent adjustments to the diagonal web members and improving installation efficiency. The hoisting frame maintains the inclination angle of the diagonal web members during hoisting, which facilitates rapid installation after hoisting to the designated position and ensures installation accuracy. The structure is simple and the operation is convenient. Attached Figure Description

[0024] This utility model provides a device for rapid hoisting and positioning of heavy-duty truss diagonal web members. The embodiments of this utility model are described below with reference to the accompanying drawings.

[0025] In the description of the embodiments of this utility model, it should be understood that the terms "top," "bottom," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, it should be noted that unless otherwise expressly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model through specific circumstances.

[0026] like Figure 1 As shown in the figure, an embodiment of this utility model discloses a rapid hoisting and positioning device for heavy-duty truss diagonal web members, including a placement frame and a hoisting frame. The placement frame is used to place the diagonal web members 15 to be installed, so that the diagonal web members 15 are placed at an installation angle. The hoisting frame is set above the placement frame and is used to hoist the diagonal web members 15, keeping them at the installation angle during the hoisting process. By setting up the placement frame and the hoisting frame, the diagonal web members 15 can be tilted according to the installation angle during placement and hoisting, eliminating the need to adjust the angle of the diagonal web members 15 during installation, thus improving installation accuracy and efficiency.

[0027] Specifically, the display rack includes a horizontal bar supporting multiple vertical placement rods 1. These vertical placement rods 1 are placed horizontally and spaced parallel to each other. The support heights of the multiple vertical placement rods 1 are different, varying in a stepped manner, thus forming a placement slope. The inclination angle of the placement slope is the same as the installation angle of the diagonal brace 15. The diagonal brace 15 is placed perpendicular to the vertical placement rods 1 on the placement slope, allowing it to be placed at an inclined installation angle.

[0028] Specifically, a reinforcing rod 2 is provided between the multiple longitudinal placement rods 1. The reinforcing rod 2 is set perpendicular to the longitudinal placement rods 1 and is fixedly connected to the multiple longitudinal placement rods 1. There are multiple reinforcing rods 2, which are equally spaced to prevent deformation of the longitudinal placement rods 1.

[0029] Specifically, the horizontal support bar is equipped with vertical support bars 3 and diagonal support bars 4. The ends of the vertical support bars 3 and diagonal support bars 4 furthest from the horizontal support bar are intersected to support the longitudinal support bar 1. The intersecting ends of the vertical support bars 3 and diagonal support bars 4 are fixedly connected, and the longitudinal support bar 1 is placed inside the intersecting end and fixedly connected to it. By setting up the vertical support bars 3 and diagonal support bars 4, the longitudinal support bar 1 can be stably supported.

[0030] Specifically, the horizontal support bar includes a horizontal horizontal bar 5 and a vertical horizontal bar 6, which are set vertically. The ends of the vertical support bar 3 and the diagonal support bar 4 closest to the horizontal support bar are fixed to the horizontal horizontal bar 5. The vertical horizontal bar 6 is fixed to both sides of the vertical support bar 3 and the side of the diagonal support bar 4 furthest from the vertical support bar 3. The vertical horizontal bar 6 provides a certain positioning function for the vertical support bar 3 and the diagonal support bar 4, making their support effect more secure.

[0031] Preferably, a placement positioning rod 7 is fixed to the lower side of the placement slope near the horizontal bar. The placement positioning rod 7 is fixed to the outside of the placement slope and is arranged parallel to the longitudinal placement rod 1. When the inclined web rod 15 is placed on the placement slope, the end of the inclined web rod 15 can abut against the placement positioning rod 7 to prevent the inclined web rod 15 from slipping.

[0032] Specifically, the lifting frame includes a lifting horizontal bar 8, on which a fixed-angle lifting rod is provided for tilting the diagonal web member 15 at the installation angle. A lifting lug 14 is fixed in the middle of the lifting horizontal bar 8 for easy connection of the lifting device.

[0033] Specifically, the fixed-angle lifting rod includes a first lifting rod 9 and a second lifting rod 10. The first lifting rod 9 and the second lifting rod 10 have different lengths and are vertically installed. The tops of the first lifting rod 9 and the second lifting rod 10 are fixedly connected to the lifting horizontal rod 8. The distance between the first lifting rod 9 and the second lifting rod 10 is the same as the horizontal distance between the two lifting lugs 14 on the inclined web rod 15 when it is placed at an angle. Because the first lifting rod 9 and the second lifting rod 10 have different lengths, they are used to connect the two lifting lugs 14 on the inclined web rod 15 respectively, so that the inclined web rod 15 is kept at an inclined installation angle during lifting.

[0034] Preferably, for ease of connection, the bottom of the first lifting rod 9 and the second lifting rod 10 are fixed with lifting rings, and lifting ropes are connected to the lifting rings. The lifting ropes can be connected to the lifting lugs 14 on the inclined web member 15. If the lengths of the first lifting rod 9 and the second lifting rod 10 are set according to the installation angle of the inclined web member 15, the lifting ropes connected to the first lifting rod 9 and the second lifting rod 10 can be set to the same length. In the actual construction process, if there is a deviation in the processing length of the first lifting rod 9 and the second lifting rod 10, causing a deviation between the lifting angle and the installation angle of the inclined web member 15, the lifting angle can be finely adjusted by adjusting the length of the lifting ropes at the bottom of the first lifting rod 9 and the second lifting rod 10 to ensure that the lifting angle is consistent with the installation angle.

[0035] Preferably, a lifting reinforcement rod 13 is fixed between the first lifting rod 9 and the second lifting rod 10. The lifting reinforcement rod 13 is fixed at an angle.

[0036] Example: A rapid hoisting and positioning device for heavy-duty truss diagonal web members, comprising a placement frame and a hoisting frame. Both the placement frame and the hoisting frame are fixed by welding. The placement frame includes a horizontal placement bar, on which multiple longitudinal placement bars 1 are supported. The multiple longitudinal placement bars 1 are placed horizontally and are arranged parallel to each other at intervals. The support heights of the multiple longitudinal placement bars 1 are different, with the heights varying in a stepped manner, so that the multiple longitudinal placement bars 1 form a placement slope. The inclination angle of the placement slope is the same as the installation angle of the diagonal web member 15. Placement reinforcing bars 2 are provided between the multiple longitudinal placement bars 1. The placement reinforcing bars 2 are set perpendicular to the longitudinal placement bars 1 and are fixedly connected to the multiple longitudinal placement bars 1. There are multiple placement reinforcing bars 2, which are arranged at equal intervals. The horizontal placement bar is provided with vertical support bars 3 and diagonal support bars 4. The ends of the vertical support bars 3 and diagonal support bars 4 away from the horizontal placement bar are arranged crosswise to support the longitudinal placement bars 1. The cross ends of the vertical support bars 3 and diagonal support bars 4 are fixedly connected, and the longitudinal placement bars 1 are placed inside the cross ends and fixedly connected to the cross ends. The horizontal support includes a transverse horizontal bar 5 and a longitudinal horizontal bar 6, which are vertically arranged. A vertical support bar 3 and a diagonal support bar 4 are fixed to the transverse horizontal bar 5 at their ends near the horizontal support bar. The longitudinal horizontal bar 6 is fixed to both sides of the vertical support bar 3 and to the side of the diagonal support bar 4 away from the vertical support bar 3. A positioning bar 7 is fixed to the horizontal support bar near the lower side of the inclined plane. The positioning bar 7 is fixed to the outside of the inclined plane and is parallel to the longitudinal horizontal bar 1. The hoisting frame includes a hoisting horizontal bar 8, which has fixed-angle suspension rods. A lifting lug 14 is fixed in the middle of the hoisting horizontal bar 8. The fixed-angle suspension rods include a first suspension rod 9 and a second suspension rod 10, which are of different lengths and are vertically arranged. The tops of the first suspension rod 9 and the second suspension rod 10 are fixedly connected to the hoisting horizontal bar 8. The distance between the first suspension rod 9 and the second suspension rod 10 is the same as the horizontal distance between the two lifting lugs 14 on the inclined web bar 15 when the horizontal support is tilted. The bottom of the first lifting rod 9 and the second lifting rod 10 are fixed with lifting rings, and lifting ropes are connected to the lifting rings. The lifting ropes can be connected to the lifting lugs 14 on the inclined web member 15. A lifting reinforcement rod 13 is fixed between the first lifting rod 9 and the second lifting rod 10. The lifting reinforcement rod 13 is fixed at an angle and crosses each other.

[0037] A construction method for a rapid hoisting and positioning device for heavy truss diagonal web members as described above includes the following steps:

[0038] S1. Calculate the installation angle of the diagonal brace at high altitude using appropriate software. Based on the installation angle of the diagonal brace 15, manufacture a placement frame and a hoisting frame to ensure that the placement angle of the placement frame and the hoisting angle of the hoisting frame are consistent with the installation angle.

[0039] S2. After the diagonal bracing 15 is transported to the construction site, the diagonal bracing 15 is placed on the placement frame in sequence using a lifting device. The ends of the diagonal bracing 15 are held against the placement positioning rod 7 to prevent the diagonal bracing 15 from slipping.

[0040] S3. Connect the hoisting frame to the lifting device, connect the hoisting rope of the hoisting frame to the lifting lug 14 on the inclined web member 15, and hoist the inclined web member 15 at the installation angle to the installation position for docking and fixing.

[0041] S4. Repeat the above operation to hoist and install the next truss diagonal web member 15.

[0042] The advantages and positive effects of this utility model are:

[0043] 1. After the truss diagonal web members are transported to the construction site, they can be directly unloaded onto the placement frame. The placement angle of the placement frame is consistent with the installation angle of the diagonal web members, avoiding multiple adjustments to the diagonal web members later and improving installation efficiency.

[0044] 2. The hoisting frame maintained the tilt angle of the diagonal bracing during hoisting, which facilitated rapid installation after being hoisted to the designated position and ensured installation accuracy.

[0045] 3. Simple structure and easy operation.
