Description

Technical Field

[0001] The utility model relates to the technical field of steel structure installation, in particular to a non-destructive steel structure tooling positioner. Background Art

[0002] With the rapid growth of my country's national economy and the research of architectural theory, the requirements for architectural space configuration are gradually increasing, especially for large cultural centers, sports centers, and exhibition halls, which are often used as landmark buildings in cities. The demand for spatial modeling is more flexible, and the layout of steel structures and curtain walls is more flexible and diversified. At present, lightweight components are often used in building structures, such as thin-walled steel components and curtain walls. For lightweight steel components, conventional steel structure welding is used. Repeated welding can easily damage the material of steel components or curtain wall keels, forming hidden quality defects; and temporary welding fixation requires workers to hold the welding gun in one hand and fix the steel component with the other hand, which is prone to deviations and causes inaccurate positioning. Summary of the invention

[0003] The utility model aims to solve the deficiencies of the prior art and provide a non-destructive steel structure tooling locator.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a non-destructive steel structure tooling locator, including a PVC guide tube, a connecting frame, and an electromagnet bar. The connecting frame is installed at the bottom of the inner wall of the PVC guide tube, a handle is installed on the top of the PVC guide tube, fixed frames are symmetrically installed on both sides of the bottom of the connecting frame, the electromagnet bar is installed at the bottom of the fixed frame, and a crossed cross line is provided on the connecting frame, and the intersection point of the cross line coincides with the center point of the PVC guide tube.

[0005] Particularly, the component to be installed is a rectangular box, the PVC guide tube is a rectangular tube, the cross section of the connecting frame is rectangular, the bottom of the connecting frame is composed of four mutually interlocking channel steels, and a first corner brace is provided at the angle between two adjacent channel steels.

[0006] Particularly, the component to be installed is in the shape of a circular tube, the PVC guide tube is a circular tube, the cross section of the connecting frame is circular, the bottom of the connecting frame is composed of two channel steels bent into a semicircular ring, and a second corner brace is provided at the joint of the two channel steels.

[0007] In particular, the wall thickness of the PVC guide tube is greater than 6 mm, and the outer diameter is 1-5 mm smaller than the inner surface diameter of the steel member.

[0008] Particularly, the connection frame is woven on the PVC guide tube by ropes or adhered to the inner wall of the PVC guide tube by strong glue.

[0009] In particular, the electromagnet bar is a suction cup type electromagnet with a plane size of 35mm×20mm. The suction force of a single suction cup is greater than or equal to 0.2KN. It is embedded in a fixed frame. The electromagnet bar uses a self-contained colloid battery and is connected in series to a power warning circuit. The alarm threshold of the power warning circuit is 30% of the rated power. The switch of the electromagnet bar extends to the handle.

[0010] The beneficial effects of the utility model are:

[0011] 1. The utility model is provided with a PVC guide tube, a connecting frame, a fixing frame, an electromagnet bar, a cross line and a handle. The connecting frame can be fully fixed to the PVC guide tube, and the electromagnet bar is firmly fixed to form a whole with the PVC guide tube. The overall structure is easy to manufacture and easy to promote.

[0012] 2. By utilizing the adsorption, fixation and magnetic breaking properties of the electromagnet bar and the steel structure, non-destructive temporary fixation is achieved, replacing temporary fixation by welding, which greatly reduces quality defects. It can achieve accurate and reliable fixation and easy removal, which not only ensures construction accuracy but also meets construction efficiency requirements.

[0013] 3. The use of PVC guide tubes can meet the requirements of light weight and rigidity, can effectively guide the components to be installed into place, and facilitate the use of tooling locators.

[0014] 4. The electromagnet bar adopts a self-contained colloidal battery with a power warning circuit. It is light in weight, can be better attached to the electromagnet bar, and is also convenient to charge. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] like Figure 1-Figure 4 As shown, a non-destructive steel structure tooling locator includes a PVC guide tube 1, a connecting frame 2, and an electromagnet bar 3. The connecting frame 2 is installed at the bottom of the inner wall of the PVC guide tube 1, a handle 4 is installed on the top of the PVC guide tube 1, fixed frames 5 are symmetrically installed on both sides of the bottom of the connecting frame 2, the electromagnet bar 3 is installed at the bottom of the fixed frame 5, and a crossed cross line 6 is provided on the connecting frame 2, and the intersection point of the cross line 6 coincides with the center point of the PVC guide tube 1.

[0023] The component to be installed is a rectangular box, the PVC guide tube 1 is a rectangular tube, the cross section of the connecting frame 2 is rectangular, the bottom of the connecting frame 2 is composed of four mutually interlocking channel steels, and a first corner brace 7 is provided at the angle between two adjacent channel steels.

[0024] The component to be installed is a round tube, the PVC guide tube 1 is a round tube, the cross section of the connecting frame 2 is circular, the bottom of the connecting frame 2 is composed of two channel steels bent into a semicircular ring, and the two channel steels are connected at the joint to form a second corner brace 8. If the component to be installed is an N-sided shape (N is usually less than 6), N small channel steels that bite each other are used.

[0025] To avoid deformation and isolate the suction force of the outer sleeve and the electromagnet bar 3, the wall thickness of the PVC guide tube 1 is greater than 6 mm. To facilitate the installation of the components to be installed, the outer diameter of the PVC guide tube 1 is 1-5 mm smaller than the inner diameter of the steel component.

[0026] The connection frame 2 is woven on the PVC guide tube 1 by ropes, or is adhered to the inner wall of the PVC guide tube 1 by using strong glue 9.

[0027] The electromagnet bar 3 is a suction cup type electromagnet with a plane size of 35mm×20mm. The suction force of a single suction cup is greater than or equal to 0.2KN and is embedded in the fixed frame 5. The electromagnet bar 3 uses a self-contained colloid battery and is connected in series with a power warning circuit. The alarm threshold of the power warning circuit is 30% of the rated power. When the power is lower than 30% of the rated power, it will automatically alarm and charge. The switch of the electromagnet bar 3 extends to the handle 4.

[0028] The crosshairs 6 are arranged on the connection frame 2 at the bottom of the PVC guide tube 1 and are generally formed by two cross lines connecting corresponding corner points; for a circular cross section, two cross lines can be arranged at any two non-overlapping diameters.

[0029] A handle 4 is provided on the top of the PVC guide tube 1 to control the switch of the electromagnet bar 3, so as to facilitate the removal of the tooling positioner after the stainless steel sleeve is welded in place in the later stage.

[0030] When the utility model works, it includes the following steps:

[0031] S1. Establish a parametric model and read the coordinates of the two points where the root of the N-gon component intersects with the main steel structure. It can be the center coordinate + one corner point, or the coordinates of two corner points, which are recorded as point O (Xi, Yi); point B (Xj, Yj); the intersection of the cross line 6 is the root center point Mi;

[0032] S2. Using the coordinate data in S1, use an optical measuring instrument (usually a total station) to measure and place the left side of each point on the surface of the steel component and mark it;

[0033] S3, align the two points of the tooling locator with the above-mentioned measuring points, and press the switch on the handle 4 to make the tooling locator adsorbed and fixed on the surface of the steel structure;

[0034] S4. Use the lifting equipment to assist the rear installation component in position and push it into the bottom from the head of the positioning tooling;

[0035] S5. Connect the components to be installed with the main steel structure;

[0036] S6. Turn off the switch on the handle 4 to disengage the tooling positioner from the main steel structure, and then pull the handle 4 outward to take out the tooling positioner.

The electromagnet bar 3 is conveniently fixed and demagnetized by adsorption and demagnetization between the steel structure to achieve lossless temporary fixation, replacing welding temporary fixation, greatly reducing quality defects, and can be firmly fixed and easily removed, thereby ensuring construction accuracy and meeting construction efficiency requirements. The PVC guide tube 1 is adopted to meet the requirements of light weight and rigidity, and can effectively guide the components to be installed into place, making it convenient to take the tooling locator. The electromagnet bar 3 adopts a self-contained colloid storage battery with a power warning circuit, which is light in weight, can be better attached to the electromagnet bar 3, and is also convenient to charge.
