Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a scaffolding-type steel-wood joint aerial installation and fixing device and installation method. Background Technology

[0002] When installing a large-span steel-frame timber arch hybrid structure, an aerial work platform is designed based on the lowest point of the structure. For example, patent application CN202511120507.5 discloses a sliding trolley and its method for constructing large-span structures, including a modular platform, assembly supports, and a traveling mechanism. The modular platform consists of four sets, each located at one of four assembly positions. Each platform includes a splicing upper chord, a splicing lower chord, a reinforcing beam, and multiple sets of connecting support structures. Multiple sets of traveling mechanisms are installed under the reinforcing beam. The traveling mechanism includes a guide support structure, a traveling structure, and a lifting support structure. The traveling structure is fixedly installed under the reinforcing beam, and the guide support structure is bolted to the base. The traveling structure is connected to the guide support structure. Multiple sets of lifting support structures are evenly spaced and installed at equal intervals on the middle of the reinforcing beam and the base. By utilizing the four sets of traveling mechanisms, the upper connecting structure, assembly supports, and brackets to move back and forth under the large-span structure, construction efficiency is improved.

[0003] However, the steel-wood joint is located at a certain height from the high-altitude operation platform. Traditional methods still require using a crane to lift the steel structure for a long time to complete the installation of the steel-wood joint, which is difficult to install and cannot guarantee the installation accuracy. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide an aerial installation and fixing device and installation method for scaffold-type steel-wood joints, so as to solve the problems of high difficulty and poor installation accuracy of existing steel-wood joints in high-altitude hoisting and installation.

[0005] In a first aspect, this application provides a scaffold-type steel-wood joint aerial installation and fixing device, applied to the connection of a steel box and a wooden arch assembly, wherein the wooden arch assembly includes two opposing wooden arches, and the steel box is located between the wooden arches; the installation and fixing device includes: An aerial work platform is located below the steel box and each of the wooden arches; A support assembly is located on the upper part of the aerial work platform. The support assembly includes a first bracket located at the bottom of the steel box between two wooden arches; a second bracket located between the two wooden arches on both sides of the steel box; a first wooden beam is provided between the first bracket and the steel box, and a second wooden beam is provided between the second bracket and the wooden arches; the first bracket and the second bracket are connected by a connecting assembly.

[0006] In some embodiments, the first support includes a plurality of first vertical support rods arranged in a straight line along the length of the first timber. Each first vertical support rod has a first concave groove at its top, the first timber is located in the first concave groove, and the upper part of the first timber is located outside the first concave groove.

[0007] In some embodiments, a first rubber gasket is provided between the first wooden beam and the steel box.

[0008] In some embodiments, the first vertical support rods are connected by a first diagonal brace and a first horizontal bar.

[0009] In some embodiments, the second support includes multiple second vertical support rods arranged in a straight line along the length of the second timber. Each second vertical support rod has a second concave groove at its top, the second timber is located in the second concave groove, and the upper part of the second timber is located outside the second concave groove.

[0010] In some embodiments, a second rubber gasket is provided between the second timber and the wooden arch.

[0011] In some embodiments, the connecting assembly includes a plurality of second horizontal bars and a second diagonal brace located between the first vertical support rod and the second vertical support rod.

[0012] In some embodiments, multiple tie rods are provided between the two wooden arches and the steel box between them.

[0013] Secondly, embodiments of the present invention provide an installation method based on an aerial installation and fixing device for scaffold-type steel-wood joints, comprising the following steps: S01. Construct an aerial work platform; S02. Construct the first support frame, the second support frame, and the connecting components under the wooden arch and the steel box; S03. Install the first timber on the top of the first support and install the second timber on the top of the second support. S04. Install two wooden arches on the second timber in a direction perpendicular to the second timber. S05. Use a crane to lift the steel box to the designed position between the two wooden arches; S06. Connect the two wooden arches and the steel box; S07. Remove the first support, the second support, the connecting components, the first timber and the second timber.

[0014] In some embodiments, along the length of the first timber, first vertical support rods with first concave grooves on their tops are sequentially installed, with first diagonal braces and first horizontal bars connecting the first vertical support rods, placing the first timber in the corresponding first concave grooves; and / or A first rubber pad is laid on top of the first timber, and the first rubber pad is located at the bottom of the steel box; and / or

[0015] Along the length of the second timber, install the second vertical support rods, each with a second concave groove at the top; and / or Install multiple second horizontal bars and second diagonal braces between the first and second vertical support rods; and / or A second rubber pad is laid on top of the second timber, and the second rubber pad is located at the bottom of the second timber.

[0016] Beneficial effects: This application presents an integrated solution for building a "micro-support structure + timber support" on an aerial work platform. Specifically, the micro-support structure, consisting of a first bracket, a second bracket, and connecting components, combined with timber support, can continuously provide stable support for the steel box after the crane is removed, significantly improving installation accuracy and operational safety, and effectively reducing construction costs.

[0017] This application describes the construction of a precision support system—a small-scale micro-support structure (scaffolding)—on a high-altitude operating platform. This micro-support structure covers steel-wood joints, is slightly lower in height than the installation location, and has a first and second timber beam at the top. This system is quick to construct, saves materials, and is easy to install.

[0018] This application combines an aerial work platform (worker's work surface) with a small-scale micro-support structure (steel box load-bearing) to form an integrated "work-support" system, realizing the functional synergy of the two and improving installation efficiency and accuracy.

[0019] For areas difficult for cranes to reach, this application allows for flexible construction of small-scale micro-support structures with materials transported via ladders. The shape of the first timber can be adjusted according to the steel box, such as rectangular, circular, or irregular shapes, making it suitable for various steel-wood joint types (e.g., steel box and timber beam, steel column and timber roof). The small-scale micro-support structure and the high-altitude operating platform move together. After the steel-wood joint is installed, the top part of the small-scale micro-support structure is removed from the first and second timber, thus separating the small-scale micro-support structure from the steel-wood joint, reducing material loss costs, equipment rental fees, component processing and maintenance costs.

[0020] This application achieves high precision by pre-adjusting the height of the scaffolding, allowing the steel box to be placed directly in the designed position. Attached Figure Description
