Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to auxiliary devices and methods for positioning and installing steel-wood joint insert plates. Background Technology

[0002] Currently, the thickness of steel-wood node inserts is generally above 20mm, using bevel welding. The positioning, processing, and installation of steel-wood node inserts include digital template-assisted positioning and installation, robotic automated positioning and installation, and manual installation. The high initial investment cost of digital template-assisted positioning and installation restricts its widespread application. Each type of node requires customized templates, with template design and manufacturing costs accounting for approximately 5%-8% of the total project cost, resulting in poor economic efficiency and significant limitations in adaptability. The huge investment required for robotic automated positioning and installation is the primary obstacle; furthermore, the high technical threshold is a prominent issue. From programming and debugging to daily maintenance, professional technicians are needed, and there is currently a severe shortage of such talent in the industry, hindering the widespread application of this technology. Manual installation relies mainly on the experience and skill level of construction workers to position and install the steel-wood node inserts. Because steel-wood node inserts are prone to generating significant residual stress due to high temperatures, large residual deformation occurs during welding, leading to internal bending and welding deformation. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a steel-wood joint insert plate positioning and installation auxiliary device and installation method to solve the problem that the insert plate is prone to internal bending and welding deformation due to the prior art.

Each row of steel-wood node insert plates is provided with multiple rows of holes, and the holes on adjacent rows of steel-wood node insert plates are aligned.

[0005] The auxiliary device includes:

[0006] The tie rod passes through the holes that are aligned on the multiple rows of steel and wood node inserts;

[0007] A limiting sleeve is fitted onto the tie rod between adjacent steel-wood node insert plates.

[0015] The positioning mechanism includes multiple horizontal and vertical measuring rulers, which are arranged in a staggered manner. Detection holes are provided at the intersections of the horizontal and vertical measuring rulers, and these detection holes are aligned with multiple rows of holes on each row of the steel-wood node insert plate.

It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles disclosed in this application.

[0041] Please see Figure 1 , Figure 2 and Figure 3In the first aspect, embodiments of this application provide a positioning and installation auxiliary device for steel-wood node inserts 1, which is applied to steel-wood node inserts 1 arranged in multiple rows. Each row of steel-wood node inserts 1 is provided with multiple rows of holes 2, and the holes 2 on adjacent rows of steel-wood node inserts 1 are aligned.

[0042] The auxiliary device includes:

[0043] The tie rod 3 passes through the holes 2 that are aligned on the multiple rows of steel and wood node insert plates 1;

[0044] The limiting sleeve 4 is sleeved on the tie rod 3 between the adjacent steel and wood node insert plates 1.

[0045] The fastening mechanism is provided at both ends of the pull screw 3, and the fastening mechanism fixes the end of the pull screw 3 to the outside of the corresponding steel-wood node insert plate 1.

[0046] In this application, tie rods 3 are inserted between the alignment holes 2 between multiple rows of steel-wood node insert plates 1, and limiting sleeves 4 of equal length are made according to the positioning distance between adjacent steel-wood node insert plates 1. The tie rods 3 are inserted into the limiting sleeves 4. The multiple rows of steel-wood node insert plates 1 are connected into a whole by fastening the tie rods 3, the limiting sleeves 4 and the fastening mechanism. Then the steel-wood node insert plates 1 are welded, which avoids residual deformation caused by residual stress and ensures the positioning accuracy of the steel-wood node insert plates 1. There will be no bending or welding deformation of the plate.

[0047] The limiting sleeve 4 of this application has flat ends, and when in use, the tie rod 3, anchor plate 5 and anchor bolt 6 are used to apply pre-tightening force to make the parallelism between the steel and wood node insert plates 1 consistent.

[0048] The tie rod 3, the limiting sleeve 4, the fastening mechanism, and the steel-wood node insert plate 1 in this application are all recyclable components that can be recycled, reducing material loss costs, equipment rental fees, and component processing and maintenance costs.

[0049] For example, the limiting sleeve 4 is a limiting steel pipe with flat ends.

[0050] Please see Figure 3 In some embodiments, at least half of the alignment holes 2 on the multiple rows of steel-wood node insert plates 1 are provided with the tie rods 3.

[0051] At least half of the alignment holes 2 in this application are provided with the tie rods 3 to reduce residual deformation during welding.

[0052] For example, each row of the steel-wood node insert plate 1 is provided with 4 rows of holes 2, with 4 holes 2 in each row. All holes 2 are arranged in an array, with the top and bottom 4 holes 2, for a total of 8 holes 2, all equipped with tie rods 3. During processing, tie rods 3, limiting sleeves 4, and fastening mechanisms are first installed at the holes 2 at the 4 corner points, respectively. This provides initial positioning of the steel-wood node insert plate 1 in the circumferential direction, ensuring its stability and flatness. Then, tie rods 3, limiting sleeves 4, and fastening mechanisms are installed in the remaining holes 2. Installing tie rods 3, limiting sleeves 4, and fastening mechanisms in half of the holes 2 reduces residual deformation during welding and ensures the positioning accuracy of the steel-wood node insert plate 1, allowing the steel-wood node to be installed smoothly.

[0053] Please see Figure 1 and Figure 2 In some embodiments, the fastening mechanism includes an anchor plate 5 sleeved on the end of the tie rod 3 and abutting against the outside of the corresponding steel-wood node insert 1, wherein an anchor bolt 6 is provided on the end of the tie rod 3 on the side of the anchor plate 5 away from the steel-wood node insert 1.

[0054] Please see Figure 1 In some embodiments, multiple rows of the steel-wood node inserts 1 are welded to the steel structure body 7.

[0055] Furthermore, multiple rows of steel-wood node inserts 1 are provided on both sides of the main steel structure 7.

[0056] Please see Figure 6 and Figure 7 Furthermore, a reaction frame 11 is provided below the main steel structure 7, and jacks 12 are provided on the upper part of the reaction frame 11. There are four jacks 12 located around the lower perimeter of the main steel structure 7.

[0057] It is understandable that when the main steel structure and the multiple rows of steel-wood node inserts 1 on both sides are installed into the wooden arch from top to bottom, a reaction frame 11 is erected. When the multiple rows of steel-wood node inserts 1 collide with the wooden arch and the friction is too great, the main steel structure is lifted by four-point jacks 12 to reduce the friction and allow the multiple rows of steel-wood node inserts 1 to slide smoothly to the designed position.

[0058] Please see Figure 4 and Figure 5 In some embodiments, the auxiliary device further includes a positioning mechanism, comprising multiple horizontal measuring rulers 8 and vertical measuring rulers 9, which are arranged in a staggered manner. Detection holes 10 are provided at the intersection points of the horizontal measuring rulers 8 and vertical measuring rulers 9, and the detection holes 10 are aligned with multiple rows of holes 2 on each row of steel-wood node insert plates 1.

[0059] For example, the positioning mechanism includes two transverse side span angle steels arranged laterally, two transverse mid-span channel steels arranged between the transverse side span angle steels, and multiple vertical angle steels arranged perpendicularly to the transverse side span angle steels and the transverse mid-span channel steels respectively. The junction of the vertical angle steels with the transverse side span angle steels and the transverse mid-span channel steels is a detection hole 10.

[0060] It is understandable that the vertical angle steel is welded and fixed to the horizontal side span angle steel and the horizontal mid-span channel steel.

[0061] Please see Figure 1 , Figure 2 and Figure 3 Secondly, embodiments of this application provide a method for installing steel-wood node inserts based on a steel-wood node insert positioning and installation auxiliary device, comprising the following steps:

[0062] S01, Multiple rows of holes 2 are set in an array for each row of steel-wood node insert plate 1;

[0063] S02. Insert the tie rod 3 into the hole 2 that is aligned on the multi-row steel-wood node insert plate 1;

[0064] S03. Based on the spacing between adjacent steel-wood node insert plates 1, a limiting sleeve 4 of the same length as the spacing between adjacent steel-wood node insert plates 1 is made, and a tie rod 3 is inserted into the limiting sleeve 4.

[0065] S04. Install the fastening mechanism at both ends of the corresponding tension screw 3.

[0066] In S01:

[0067] Please see Figure 3 In some embodiments, multiple rows of holes 2 are created using scribing and CNC machine tool laser cutting technology. After the holes 2 are processed, a positioning mechanism is used to compare the multiple rows of holes 2 on each row of steel-wood node insert plates 1. The purpose is to detect the machining accuracy of the diameter of the holes 10 2 and the relative distance between the holes 2.

[0068] Please see Figure 4 and Figure 5 Furthermore, the positioning mechanism includes multiple horizontal measuring rulers 8 and vertical measuring rulers 9, which are arranged in a staggered manner. Detection holes 10 are provided at the intersection points of the horizontal measuring rulers 8 and vertical measuring rulers 9, and the detection holes 10 are aligned with the multiple rows of holes 2 on each row of the steel-wood node insert plate 1.

[0069] In S02:

[0070] Please see Figure 3 In some embodiments, the tie rods 3 are provided on at least half of the alignment holes 2 on the multiple rows of steel-wood node insert plates 1.

[0071] In S04:

[0072] Please see Figure 1 In some embodiments, the fastening mechanism includes an anchor plate 5 sleeved on the end of the tie rod 3 and abutting against the outside of the corresponding steel-wood node insert 1, wherein an anchor bolt 6 is provided on the end of the tie rod 3 on the side of the anchor plate 5 away from the steel-wood node insert 1.

[0073] Furthermore, multiple rows of steel-wood node insert plates 1, which are equipped with tie rods 3, limiting sleeves 4, and limiting sleeves 4, are welded onto the steel structure body 7. Multiple rows of steel-wood node insert plates 1 are welded to both sides of the steel structure body 7.

[0074] Please see 6 and Figure 7 Furthermore, a reaction frame 11 is installed below the main steel structure 7, and four jacks 12 are installed on the upper part of the reaction frame 11. The four jacks 12 are located around the lower perimeter of the main steel structure 7.
