Description

Technical Field

[0001] The present invention relates to the technical field of roofing engineering, and more particularly to a fish-scale superimposed roof installation structure and a construction method. Background Art

[0002] The curved surface of large venues adopts fish-scale superimposed roofs. Due to the large construction volume and the large number of roof unit components to be installed, the position of the panels to the steel structure is not uniform, and the height of the four corner points of the panels from the steel structure varies, resulting in a huge workload for positioning. The construction of traditional superimposed roof panel units depends on the installation of the previous panel unit, and large-scale construction cannot be carried out directly, resulting in low construction efficiency. At the same time, the curved surface characteristics often lead to excessively high processing costs for the roof units. Summary of the Invention

[0022] The first supporting square tubes of the two groups of first supporting square tubes, the group of first supporting square tubes away from the secondary purlin, are coplanar with the top surface of the support;

[0023] The distance between the two groups of the first supporting square tubes of the same support is equal to the distance between the two groups of the second supporting square tubes, and they are arranged in a staggered and equal interval.

By deepening the design of the roof installation structure, the processing dimensions and positioning holes of each component in the roof installation structure are generated. By adjusting the installation positions of the purlins, adapters, and supports, the installation errors of the steel structure can be corrected. When installing other components of the roof installation structure, only bolts need to be assembled and fixed without re-positioning, which greatly improves the installation efficiency.

[0058] One end of the purlin support 3 passes through the waterproof and thermal insulation layer 4 and is connected to the main purlin 5; a gap is formed between adjacent roof decorative panels 20; further, the gap is 100 mm.

[0059] Working principle: During installation, first install the structural purlin 1;

[0060] Then install the adjustable support members and purlin brackets 3 on the structural purlin 1;

[0061] Holes are opened on the waterproof and thermal insulation layer 4 for the purlin support 3 to pass through, and the waterproof and thermal insulation layer 4 is installed on the adjustable support member 2;

[0062] Adjust the elevation of the top surface of the purlin 3, determine the installation position of the adapter 7, and install the adapter 7;

[0063] After the adapter 7 is installed, the main purlin 5 is installed;

[0064] The secondary purlin 6 is connected to the main purlin 5;

[0065] The primary purlin 5 has two circular holes at the secondary purlin 6 mounting point, and two identical circular holes are located at the ends of the secondary purlin 6. The primary and secondary purlins 6 are connected via a purlin adapter 7, an L-shaped steel angle with four elongated holes for securing and adjusting the secondary purlin 6.

[0066] Support 8 installation;

[0067] The roofing decorative panels 20 are installed.

[0068] In some possible implementations, in order to effectively achieve the telescopic adjustment of the purlin 3 and meet the installation requirements of the adapter 7 at different height positions;

[0069] The purlin support 3 includes a lower purlin support 31 with one end mounted on the structural purlin 1 and the other end passing through the waterproof insulation layer 4, an upper purlin support 32 fitted with the lower purlin support 31 and slidingly matched along the axial direction of the lower purlin support 31, and a support plate 33 mounted on the upper purlin support 32.

[0070] In some possible implementations,

[0071] The upper purlin support 32 is sleeved on the outer side of the lower purlin support 31 and connected by positioning bolts. A plurality of positioning holes are provided on the upper purlin support 32 and the lower purlin support 31 along the axial direction of the upper purlin support 32 .

[0072] The upper purlin support 32 and the lower purlin support 31 are both cylindrical sleeve structures. One end of the lower purlin support 31 is installed on the structural purlin 1 and the other end passes through the waterproof and thermal insulation layer 4 and is connected to the upper purlin support 32 located on the waterproof and thermal insulation layer 4. After the elevation of the support plate 33 is adjusted to the specified position, the upper purlin support 32 and the lower purlin support 31 are fixed with bolts;

[0073] In some possible implementations,

[0074] The support plate 33 is circular and is provided with positioning grids. The positioning grids include a plurality of first positioning baselines 331 equidistantly arranged along the axial direction of the main purlin 5 and a plurality of second positioning baselines 332 equidistantly arranged along the length direction of the positioning baselines.

[0075] Furthermore, the distance between two adjacent sets of first positioning baselines 331 or second positioning baselines 332 is 10 mm;

[0076] This configuration makes it easier to install and position the adapter 7.

[0077] In some possible implementations,

[0078] It also includes an adapter 7 for connecting two adjacent main purlins 5 and mounted on the support plate 33;

[0079] The cross section of the adapter 7 is L-shaped, comprising a bottom plate mounted on and connected to the support plate 33 , and a connecting plate perpendicularly connected to the bottom plate and connected to one end of two adjacent main purlins 5 .

[0080] In some possible implementations,

[0081] Each group of main purlins 5 comprises a plurality of main purlins 5 connected in sequence. Among two adjacent main purlins 5, one group of main purlins 5 is provided with waist-shaped long holes which are mounted in cooperation with the adapter 7 and whose long axis is arranged along the rectangular shape of the main purlin 5, and the other group of main purlins 5 is provided with round holes which are mounted in cooperation with the adapter 7.

[0082] The purpose of providing the waist-shaped long holes is to avoid the main purlin 5 from being unable to be installed due to processing errors, and to prevent the main purlin 5 from thermal expansion and contraction causing the roof decorative board 20 to be deformed after installation;

[0083] There are multiple groups of supports 8 installed on each group of secondary purlins 6, and the heights of the multiple groups of supports 8 decrease in sequence along the length direction of the secondary purlins 6;

[0084] Support members for supporting the installation of the roofing decorative panels 20 are provided on the outer side of each group of supports 8 .

[0085] Furthermore, the connecting plate is provided with mounting holes for use with round holes and waist-shaped long holes, and the bolts are passed through the holes to cooperate with the round holes or waist-shaped long holes to achieve the supporting connection between the adapter 7 and the main purlin 5;

[0086] In some possible implementations,

[0087] The support 8 is an angle steel, comprising a connecting surface connected to the secondary purlin 6, and a mounting surface provided on a side of the connecting surface away from the secondary purlin 6 and connected to the connecting surface to form an L-shaped structure.

[0088] Each set of support members includes two sets of first support square tubes 81 spaced apart on the mounting surface along the length direction of the support 8, and two sets of second support square tubes 82 spaced apart on the connecting surface along the length direction of the support 8;

[0089] Of the two groups of first supporting square tubes 81 , the group of first supporting square tubes 81 away from the secondary purlin 6 is coplanar with the top surface of the support 8 ;

[0090] The distance between the two groups of the first supporting square tubes 81 and the distance between the two groups of the second supporting square tubes 82 of the same support 8 are equal and are staggered and arranged at equal intervals.

[0091] That is, when the gap between two adjacent groups of roofing decorative panels 20 is 100 mm, the distance between two groups of the first supporting square tubes 81 or the distance between two groups of the second supporting square tubes 82 on the same support 8 is 200.

[0092] With the above arrangement, in the longitudinal direction of the main purlin 5, a small piece of roofing decorative board 20 is supported by two adjacent sets of supports 8, one set of first supporting square tubes 81 coplanar with the top surface of the supports 8, and one set of first supporting square tubes 81 not coplanar with the other set of supports 8; so that in the longitudinal direction of the main purlin 5, the two adjacent sets of roofing decorative boards 20 are superimposed;

[0093] In the length direction of the secondary purlin 6, the roofing decorative panels 20 are stacked in sequence through the second supporting square tubes 82, so that all the roofing decorative panels 20 are stacked in a fish-scale shape in two directions.

[0094] In some possible implementations, in order to effectively adjust the height of the support 8 so as to meet the requirements of supporting the roofing decorative board 20;

[0095] A plurality of through holes are provided on one side of the support 8 close to the secondary purlin 6 , and the plurality of through holes are arranged along the long direction of the support 8 , and mounting holes for use with the through holes are provided on the secondary purlin 6 .

[0096] In some possible implementations, in order to effectively support and fix the waterproof and thermal insulation layers 4 at different heights;

[0097] The adjustable support member 2 includes two groups of symmetrically arranged L-shaped angle steels 21 installed on the structural purlin 1, a connecting square tube 22 located between the two groups of L-shaped angle steels 21 and slidingly matched, and a locking bolt for fixing the connecting square tube 22 and the L-shaped angle steel 21; a waist-shaped hole is provided on the side of the connecting square tube 22 that is adjacent to the L-shaped angle steel 21 and is axially arranged along the long axis direction of the purlin support 3, and a bolt mounting hole is provided on the L-shaped angle steel 21 for use with the waist-shaped hole.

[0098] A method for installing the fish-scale superimposed roof installation structure described above specifically comprises the following steps:

[0099] Step S1: Create a three-dimensional model of the main structure and roof installation structure according to the design drawing;

[0100] Specifically:

[0101] Use BIM technology to extract the roof installation structure model, and use parametric modeling methods to carry out in-depth design of the roof installation structure model;

[0102] Use parameterization to divide the positioning lines of purlins and roof decorative panels 20, and use Revit to build a parametric model of roof decorative panels 20;

[0103] By using Dynamo for reasonable panel arrangement and combining it with construction technology, the angle change of the 20-degree roof decorative panel model was controlled to achieve a fish-scale curtain wall effect. At the same time, the original design of the overlap length of each side was optimized from 200mm to 100mm, saving 25% of the aluminum veneer material. The complex hyperbolic surface was simplified into equal-sized flat plates at the same distance from each installation purlin.

[0104] Use Revit parametric modeling to further design the roof finish system, generate the processing dimensions and positioning bolt holes of each component of the roof finish system, and number and process each component;

[0105] Step S2: construct the main structure at the construction site, perform three-dimensional scanning and measurement on the completed main structure, and reversely establish a structural purlin 1 model;

[0106] Step S3: Compare and analyze the structural purlin 1 model with the three-dimensional model to obtain adjustment data;

[0107] The adjustment data includes the size of the purlin bracket 3, the installation position and elevation of the purlin bracket 3, the distance deviation data between the adapter 7 and the center of the top surface of the purlin bracket 3, and the elevation of the support 8;

[0108] Step S4: installing the purlin support 3;

[0109] According to the installation position and elevation of the purlin bracket 3 obtained, install the lower purlin bracket 31 on the structural purlin 1, install the upper purlin bracket 32, use a ruler to adjust the elevation of the support plate 33, and fix the upper purlin bracket 32 ​​to the lower purlin bracket 31 to complete the installation of the purlin bracket 3;

[0110] Step S5: installing the adapter 7;

[0111] Based on the obtained distance deviation data between the adapter 7 and the center of the top surface of the purlin 3, use a set square and a ruler to mark the installation position of the adapter 7 on the support plate 33, and install the adapter 7 on the support plate 33;

[0112] Step S6: Install the main purlin 5 and the secondary purlin 6 in sequence;

[0113] The main purlin 5 is connected to the adapter 7 by bolts. One end of the main purlin 5 is connected to the round hole set on the adapter 7, and the other end is connected to the long hole. This avoids the main purlin 5 from being unable to be installed due to processing errors, and also avoids the deformation of the decorative aluminum plate caused by the thermal expansion and contraction of the purlin.

[0114] Step S7: installing the support 8;

[0115] According to the elevation of the support 8, the support 8 is installed; specifically, the installation position of the support 8 and the secondary purlin 6 is adjusted according to the elevation of the support 8, so that the elevation of the support 8 effectively meets the installation requirements of the roof decoration;

[0116] Step S8: The roofing decorative panels 20 are installed. After installation, the gap between adjacent roofing decorative panels 20 is 100 mm.

[0117] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
