Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel-wood verticality detection, in particular to a steel-wood structure verticality detection device and method. BACKGROUND

[0002] In the field of construction engineering, especially in the field of fabricated building and large steel structure construction, the verticality of steel-wood structure (including steel-wood hybrid structure components or connecting joints) is a key quality indicator to ensure the stability and installation accuracy of the structure. Traditional steel-wood structure verticality detection methods, such as using a plumb bob, an electronic level or a laser level, have many limitations: the plumb bob measurement requires a suspension point at the top, and the electronic level and laser level usually require a stable platform or a precisely calibrated horizontal base surface. When measuring, the overall verticality of the steel-wood structure can be detected, but for very high steel-wood structures (i.e. super-high components), a single position verticality measurement cannot fully reflect the overall verticality of the structure. It is difficult to continuously and conveniently arrange multiple detection points at different heights of the component for comprehensive evaluation using traditional methods.

[0003] Therefore, there is an urgent need to develop a verticality detection device and method that is easy to operate, quick to install, and widely adaptable, especially suitable for verticality detection of high steel-wood structures. SUMMARY

[0008] As optimization, the upper part of the clamping positioning plate is rotationally connected with a first positioning block, the first positioning block is provided with a first positioning guide rod, the first positioning guide rods of the two first positioning blocks are arranged in parallel and staggered, the first positioning guide rod is provided with a rack part, a first connecting gear is arranged between the two rack parts, and when a single first positioning guide rod moves, the other first positioning guide rod is driven to move reversely and synchronously through the first connecting gear.

[0009] As optimization, the middle part of the clamping positioning plate is rotationally connected with a second positioning block, the second positioning block is provided with a connecting hole, and the end of the guide rod is arranged through the connecting hole.

[0010] The connecting hole is provided with a limiting block, and the limiting block is used for limiting the guide rod.

[0011] As optimization, the upper surface of the guide rod is recessed to form a guide groove, one end of the detection block is provided with a guide roller, and the guide roller is arranged in the guide groove.

[0012] As optimization, the second positioning block is connected with a second positioning guide rod, the curvature of the second positioning guide rod is the same as that of the guide rod, the second positioning guide rod is provided with a rack segment, a second connecting gear is arranged between the rack segments of the two second positioning guide rods, and the rack segments of the two second positioning guide rods are relatively engaged and connected through the second connecting gear.

[0013] As optimization, the detection scale is in the shape of an arc, the detection scale is coaxially arranged with the guide rod, the counterweight rod is located at the lower side of the detection scale, and a detection marker is connected between the counterweight rod and the detection block, and the detection marker is located at the rear side of the detection scale.

DETAILED DESCRIPTION

[0030] As shown in Figures 1-7 , a steel wood structure verticality detection device, comprising a positioning installation part and a detection part, the positioning installation part comprises two oppositely arranged clamping positioning plates 1, the detection part comprises a circular arc-shaped guide rod 2 and a detection assembly movably arranged on the guide rod 2, the guide rod 2 is arranged between the two clamping positioning plates 1, the lower side of the middle part of the guide rod 2 is fixed with a detection ruler 3, the detection assembly comprises a detection block 4 in sliding connection with the guide rod 2, the lower side of the detection block 4 is provided with a counterweight rod 5, when the steel wood structure to be detected is inclined, the detection block 4 moves along the guide rod 2 under the action of gravity, and the offset angle of the steel wood structure to be detected in the vertical direction is determined by the detection ruler 3.

[0031] High-strength aluminum alloy is adopted for casting, and an anti-skid rubber layer is arranged on the inner side. When in use, the angle of the clamping positioning plate 1 can be adjusted, so that the clamping positioning plate 1 is conveniently fixed to the outer side of different steel wood structures.

[0032] The guide rod 2 and the detection ruler 3 are located on the outer side of the steel wood structure and do not contact the steel wood structure, the detection block 4 moves along the guide rod 2 under the action of gravity, and the detection block 4 and the guide rod 2 are smooth and have no resistance.

[0033] The tail of the counterweight rod 5 is lead-filled (the mass is adjustable), the detection marker 17 is made of transparent acrylic material and is marked with a red reference line, and visual obstruction is avoided when viewed from the rear of the detection ruler 3.

[0034] The detection ruler 3 is an arc-shaped scale disc, the minimum scale is 0.5°, and a fluorescent coating is arranged in the detection ruler 3 to support reading in a weak light environment.

[0035] As shown in Figure 1 , Figure 5 and Figure 6 , the counterweight rod 5 is provided with a limit hole 6, the counterweight rod 5 is detachably connected with an expansion module, the expansion module comprises a connecting seat 7 and an expansion module, the connecting seat 7 comprises two hinged connecting parts, the connecting parts are detachably connected with the counterweight rod 5, a limit pin is arranged on the inner side of the connecting part, and the limit hole 6 is used for accommodating the limit pin.

[0036] The expansion assembly comprises a laser transmitter 8 and a laser receiver 9, which are respectively connected to the counterweight rods 5 of two detection devices arranged oppositely to continuously detect the verticality of the super-high steel-wood structure.

[0037] The two connecting portions are connected through spring rotating shafts, so that the two connecting portions have a tendency to rotate towards the center and can be clamped to the outside of the counterweight rods 5.

[0038] As shown in Figure 5 , the upper part of the clamping positioning plate 1 is rotationally connected with first positioning blocks 10, the first positioning blocks 10 are provided with first positioning guide rods 11, the first positioning guide rods 11 of the two first positioning blocks 10 are arranged in parallel and staggered, the first positioning guide rods 11 are provided with rack portions, the first connecting gears 12 are arranged between the two rack portions, and when a single first positioning guide rod 11 moves, the other first positioning guide rod 11 is driven to move reversely and synchronously through the first connecting gear 12.

[0039] When the single-sided first positioning guide rod 11 is adjusted (such as manually pushed and pulled), the rack portion thereof drives the first connecting gear 12 to rotate, and the other side guide rod is reversely and synchronously moved through gear engagement, so that the equal-distance adjustment of the distance between the two clamping plates is realized.

[0040] A first limiting ring is arranged outside the first positioning guide rod 11 and is used for limiting the two first positioning guide rods 11 and the first connecting gear 12. The first connecting gear 12 is rotationally arranged in the first limiting ring.

[0041] As shown in Figure 5 , the middle part of the clamping positioning plate 1 is rotationally connected with second positioning blocks 13, the second positioning blocks 13 are provided with connecting holes, and the end portions of the guide rods 2 are arranged through the connecting holes.

[0042] The connecting holes are provided with limiting clamping blocks, and the limiting clamping blocks are used for limiting the guide rods 2.

[0043] The first positioning blocks 10 and the second positioning blocks 13 are arranged on the front side of the clamping positioning plate 1, and the first positioning blocks 10 and the second positioning blocks 13 are respectively provided with clamping block structures for limiting the first positioning guide rods 11 and the guide rods 2, so as to lock the relative positions of the guide rods 2 and the clamping positioning plate 1.

[0044] As shown in Figure 5 , the upper surface of the guide rod 2 is recessed to form a guide groove 14, one end of the detection block 4 is provided with a guide roller, and the guide roller is arranged in the guide groove 14.

[0045] The guide groove is used for limiting the movement of the detection block 4 to avoid the detection block 4 from being separated from the guide rod 2.

[0046] The guide rod 2 can be made of lightweight carbon fiber material, with a circular arc radius R=300mm and surface anodizing treatment. The guide groove 14 is a T-shaped groove structure, which reduces the risk of lateral deviation of the guide roller.

[0047] The detection block 4 is equipped with a guide roller with a ball bearing, which precisely matches the guide groove 14 and reduces the friction coefficient.

[0048] As shown in Figure 5 The second positioning block 13 is connected with a second positioning guide rod 15, which has the same curvature as the guide rod 2. The second positioning guide rod 15 is equipped with a rack section, and a second connecting gear 16 is arranged between the rack sections of the two second positioning guide rods 15. The rack sections of the two second positioning guide rods 15 are connected by the second connecting gear 16.

[0049] The first positioning guide rod 11 is fixedly connected with the second positioning block 13. When the two second positioning blocks 13 move along the guide rod 2, the two second positioning guide rods 15 move synchronously.

[0050] As shown in Figure 2 The detection ruler 3 is a circular arc, and is coaxially arranged with the guide rod 2. The counterweight rod 5 is located on the lower side of the detection ruler 3, and the detection marker 17 is connected between the counterweight rod 5 and the detection block 4, and is located on the rear side of the detection ruler 3.

[0051] The relative position of the detection marker 17 and the detection ruler 3 determines the vertical deviation of the steel-wood structure. When the detection block 4 moves, it drives the detection ruler to move synchronously.

[0052] As shown in Figure 4 The laser receiver 9 is equipped with a ranging scale;

[0053] As shown in Figure 4 and 8 When the height of the steel-wood structure is greater than 2m and there is deformation, at least two detection devices are arranged simultaneously, and the two detection devices are equipped with laser emitters 8 and laser receivers 9 respectively, to determine whether the installation positions of the upper and lower detection devices are in the same vertical direction.

[0054] The ranging scale determines the irradiation position of the laser, which can conveniently determine the torsion and deviation of the high steel-wood structure.

[0055] The verticality detection method comprises the following steps: fixing two detection devices at different heights of the high steel-wood structure, connecting the two detection devices with laser emitters 8 and laser receivers 9 respectively, and calibrating the upper and lower detection devices by an expansion module to detect the verticality of the high steel-wood structure in a segmented manner.

[0056] When the detection device is installed, the two clamping positioning plates 1 are clamped on both sides of the steel-wood structure, and the two clamping positioning plates 1 are installed at the same height. After installation, the positions of the clamping positioning plates 1 and the guide rods 2 are locked.

[0057] The detection block 4 and the detection ruler 3 are arranged on the outer side of the steel-wood structure. The detection block 4 moves along the guide groove under the action of gravity, and the detection block 4 drives the counterweight block to move synchronously. The detection marker 17 is located on the inner side of the detection ruler 3, and the perpendicularity of the steel-wood structure is determined by the detection ruler 3.

[0058] The light touch detection block 4 eliminates static friction. After the counterweight rod 5 is stable, the angle θ of the detection marker 17 on the detection ruler 3 is read.

[0059] When the steel-wood structure is relatively high, multiple sets of detection devices can be arranged synchronously, as shown in FIG. 5. Each set of detection devices includes two detection devices, and the two detection devices are respectively configured with a laser emitter 8 and a laser receiver 9. The emission end of the laser emitter 8 is arranged towards the detection ruler 3 of the laser receiver 9. Figure 8

[0060] The two detection devices can respectively detect the perpendicularity, and the detection device with the laser receiver 9 can determine whether there is a deviation between the two detection devices according to the received laser signal.

[0061] Through the relative detection of the upper and lower detection devices, the laser beams are emitted between the upper and lower devices, and combined with the ranging scale on the laser receiver 9, it is quickly determined that the two installation points are located on the same vertical line, and the deviation is quickly determined.

[0062] When the steel-wood structure is relatively high and has deformation such as bending and twisting, multiple detection devices arranged at different heights can be linked to continuously obtain the perpendicularity at different positions and the relative deviation angle between adjacent points, so as to accurately measure and analyze the overall perpendicularity and deformation trend of the structure.

Any appropriate changes or modifications made by any ordinary skilled person in the corresponding technical field to the steel-wood structure perpendicularity detection device and the detection method according to the claims of the present application shall fall within the patent protection scope of the present application.​
