Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, and specifically relates to a modular steel structure roof of a large-span steel structure three-dimensional warehouse. Background Art

[0002] At present, large-span steel structure three-dimensional warehouses with a span exceeding 36 meters are increasingly widely used in large buildings such as exhibition halls, stadiums, auditoriums, warehouses, and factories. The three-dimensional warehouse includes vertical columns and a steel structure roof supported on the columns. The columns can be section steel columns or concrete columns, etc. The steel structure roof includes multiple steel trusses extending longitudinally. Multiple transverse and diagonal steel pipes are welded between every two adjacent steel trusses; multiple transverse purlins are perpendicularly welded to the upper chord steel pipes of each steel truss; the roof panels of the roof are longitudinal and are fixed to each purlin by air nails. The roof panels include color steel plates and light-transmitting sunlight plates, and the color steel plates and sunlight plates are arranged at intervals on the roof.

[0003] The process of hoisting and constructing the steel structure roof of the above-mentioned prior art is generally as follows: first, the columns are erected on site; then the steel frame of the roof is assembled on the ground of the site; and winches are installed on the tops of some columns. Then, the steel frame of the steel structure roof is hoisted to the top of the columns. Then, workers perform high-altitude operations to splice and fix a steel structure extension support protruding outward from the roof at the edge of the roof and make the extension support fall and be supported on the columns; then the installation of the roof panels is carried out, that is, workers climb onto the roof and use air gun nails to fix color steel plates, sunlight plates, etc. on the roof purlins; then auxiliary structures such as lighting systems and fire protection systems are installed, that is, workers spray fireproof coatings on the roof, install wires and lamps, install water pipes and sprinklers, etc.

[0004] The steel structure roof of the above-mentioned prior art has defects in construction. Because the volume, weight, and span of the roof steel frame are all very large, in order to ensure safety, only the bare steel frame of the roof can be hoisted, and the roof panels, lighting systems, fire protection systems, etc. can only be installed by high-altitude operations after the hoisting is completed. Therefore, the workload of high-altitude operations is very large, more man-hours are required, and there are also greater high-altitude operation risks. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a large-span steel structure modular roof that can significantly reduce the workload of high-altitude operations and has a safe and stable hoisting process.

[0006] The technical solution of the utility model is to provide a large-span steel structure modular roof, which includes multiple steel trusses extending longitudinally. There are multiple transverse steel pipes and diagonal steel pipes welded between every two adjacent steel trusses; multiple transverse purlins are perpendicularly welded to the upper chord steel pipes of each steel truss; the roof panels of the roof are longitudinal, and the roof panels include color steel plates and transparent sunlight plates; the color steel plates occupying most of the roof area are fixed to each purlin by air nails. The gap between every two adjacent daylighting plates forms a light-transmitting band, and each light-transmitting band is provided with a corresponding sunlight plate. Each sunlight plate is placed on the side of the adjacent color steel plate and the sunlight plate is detachably connected to the placed color steel plate.

[0007] Compared with the prior art, the large-span steel structure modular roof with the above structure has the following advantages.

[0008] Firstly, workers nail all the color steel plates to the purlins on the ground, thus completing the installation of the roof panels in most areas of the roof. In this way, firstly, the workload of the high-altitude operation of fixing the color steel plates with air nails at high altitude is reduced; moreover, since most areas of the roof are already covered with color steel plates, there is space for operation and placement, so workers can carry out work such as spraying fireproof coatings, installing wires and lamps, installing water pipes and sprinklers on the ground in advance, thus further reducing the high-altitude operation volume of installing the lighting system and the fire protection system after hoisting; it saves time and effort, shortens the construction period, and also reduces the risk of high-altitude operation; moreover, more valuably, a small part of the area is still left before hoisting the roof. Deliberately not installing the sunlight plates on the ground but leaving them to be nailed at high altitude after hoisting to form a hollow light-transmitting band. In this way, the wind resistance during the hoisting process can be effectively reduced, making the hoisting process smoother and more stable; furthermore, although the sunlight plates are not fixed to the purlins, they are temporarily fixed to the color steel plates in advance and hoisted together with the roof. Therefore, when installing the sunlight plates later, there is no need to lift them from the ground again, but directly remove the connection with the color steel plates and then it can be easily nailed and assembled after lateral movement.

[0009] Preferably, the sunlight plate is detachably clamped to the placed color steel plate by a C-shaped buckle. The C-shaped buckle includes a C-shaped plate, a nut and a bolt. The lower plate of the C-shaped plate abuts against the clamped color steel plate. The nut is welded to the upper plate of the C-shaped plate. The bolt is screwed with the nut and the rod part of the bolt passes through the upper plate through hole and abuts tightly against the clamped sunlight plate; this structure is very convenient for disassembly and assembly. Only by tightening or loosening the bolt can the disassembly and assembly of the color steel plate and the sunlight plate be completed.

[0010] Preferably, an operation gap for assembling the extension support is reserved between the lower end of each color steel plate and the end of the steel truss. An end steel plate for covering the operation gap is provided at the lower end of each color steel plate, and each end steel plate is also detachably clamped to the lower end of the corresponding color steel plate by a C-shaped buckle; each sunlight plate is divided into upper and lower sections, and the sum of the lengths of the upper and lower sections of the sunlight plate is equal to the sum of the lengths of the color steel plate and the corresponding end steel plate; the advantages of the above structure are as follows. First, the operation space at the end of each steel truss is hollowed out, so that workers can ride on a lift truck to assemble the extension support of the steel structure at the edge of the roof and make the extension support successfully positioned on the corresponding column; after the support is positioned, it is convenient to cover the hollowed-out area at the lower end of the color steel plate with an end steel plate to complete the roof; the end steel plate is also clamped to the lower end of the color steel plate by a C-shaped buckle, which is convenient for disassembly and assembly, and the end steel plate is also hoisted integrally with the roof and does not require subsequent separate hoisting; furthermore, each sunlight plate is divided into upper and lower sections and partially overlapped. In this way, it is convenient to overlap the two sections of the sunlight plate and temporarily clamp them to the side of the corresponding color steel plate during overall hoisting, which also ensures the operation space at the end of the steel truss. After the extension support is assembled and positioned, the two sections of the sunlight plate can be quickly disassembled, and the lower end of the lower section of the sunlight plate just covers the hollowed-out area at the lower end of the light-transmitting belt.

[0011] As a further preference, each color steel plate is provided with three C-shaped buckles, namely upper, middle and lower. The upper end of the color steel plate and the upper end of the corresponding upper section of the sunlight plate are clamped by the upper C-shaped buckle. The middle section of the color steel plate, the lower end of the upper section of the sunlight plate and the upper end of the lower section of the sunlight plate overlap, and this overlapping part is clamped by the middle C-shaped buckle. The lower end of the color steel plate, the lower end of the lower section of the sunlight plate and the corresponding end steel plate overlap, and this overlapping part is clamped by the lower C-shaped buckle; in this way, after hoisting in place, the operation of nailing each sunlight plate and end steel plate at high altitude is more convenient. Only a slight movement is needed to make each plate reach the predetermined position. For example, by laterally moving the upper section of the sunlight plate, laterally moving and downwardly moving the lower section of the sunlight plate, and downwardly moving the end steel plate, the nailing position can be reached; it makes the later roof operation not require large-scale movement, is more convenient, labor-saving and easier.

[0012] As a further preference, an elastic roller is rotatably installed at the end of the lower chord steel pipe of the roof steel truss through a wheel frame, and a vertical channel steel track for cooperating with the elastic roller is provided on the inner side of the column supporting the roof; in this way, during the hoisting process, the elastic roller of each lower chord steel pipe slides in the corresponding channel steel track, so that each column provides strong guidance for each steel truss of the entire roof, further enhancing the smoothness, stability and safety of the hoisting process.

[0013] It is particularly emphasized that the core advantage of this application is that most of the roof panels, fireproof coatings, lighting systems, fire protection systems, etc. are integrated on the roof in advance to form a complete modular roof, and modular integral hoisting is carried out on it, thus significantly reducing the amount of high-altitude work. However, precisely because it provides a favorable orientation for the roof during hoisting and effectively reduces wind resistance through the hollow light-transmitting belt, the two are combined and promote each other, and together they better realize the concept of modular integral hoisting.
