Technical Field

[0001] The utility model relates to the technical field of steel structure installation, in particular to a steel structure column installation measurement and correction structure. Background Technique

[0002] Steel structure columns are one of the commonly used components in the construction process; commonly, when building factories or large-span buildings, it is necessary to first fix them vertically and then hoist and install the cross beams; therefore, whether the longitudinal steel structure columns are vertical will directly affect the accuracy of the cross beam installation; commonly, a laser level is generally used to detect whether the support columns are vertically installed; however, for the longitudinally arranged steel structure support columns, there are often anchor points or other anchor fittings for connecting the cross beams, resulting in the laser emitted by the level being blocked by the anchor points or anchor fittings, making it difficult to judge whether they are vertically installed. Content of the Utility Model

[0003] The purpose of the utility model is to solve the problems in the background technique, and propose a steel structure column installation measurement and correction structure, which sets a laser level on a movable activity platform and uses the Pythagorean theorem to measure the distance twice to judge whether the steel structure column is vertically installed.

[0004] The technical solution of the utility model, a steel structure column installation measurement and correction structure, includes an installation column, a support platform and an activity platform;

[0007] The activity platform slides along the guide rail and is limited by cooperating with the positioning notch; an installation base for connecting with a laser level is arranged on the activity platform, and a laser ranging module is integrated on the laser level.

[0008] Preferably, a through hole is left in the middle of the plug-in member, a guide post is arranged in the groove, and the guide post passes through the through hole of the plug-in member; the inner diameter of the through hole is 1.5-2 times the diameter of the guide post.

[0009] Preferably, a bubble level is arranged at the closed end of the support platform.

[0010] Preferably, the bubble level is circular.

Detailed Description of the Invention

[0023] Embodiment 1

[0024] As Figure 1-2 shown, a steel structure column installation measurement and correction structure proposed by the utility model includes an installation column 1, a support platform 2 and a movable platform 3;

[0025] The mounting post 1 is a magnetic metal plate made of ferromagnetic material, and a groove portion 11 for mating installation with the support platform 2 is reserved at its bottom; the mounting post 1 can be directly fixed on the steel structure column by magnetic adsorption, so as to facilitate judging whether it is installed vertically.

[0026] As Figure 3 shown, the middle of the support platform 2 is hollow, one end thereof is provided with a plug member 23 inserted into the groove portion 11 of the mounting post 1, and the other end is closed; two symmetrical guide rails 21 are arranged along the inner side wall of the hollow portion of the support platform 2, and a plurality of positioning notches 22 are arranged on the guide rails 21; the movable platform 3 slides along the guide rails 21 and is limited in cooperation with the positioning notches 22; an installation base 33 for connecting with a laser level is arranged on the movable platform 3, and a laser ranging module is integrated on the laser level. A bubble level 4 is arranged on the closed end of the support platform, and the bubble level 4 is circular.

[0027] In this embodiment, a through hole is reserved in the middle of the plug member 23, a guide post 12 is arranged in the groove portion 11, and the guide post 12 passes through the through hole of the plug member 23; the inner diameter of the through hole is 1.5 - 2 times the diameter of the guide post 12. As Figure 4 shown, when the mounting post 1 is directly fixed on the steel structure column by magnetic adsorption, the guide post 12 maintains magnetic attraction with the A side wall of the plug member 23; when the steel structure column is vertical, at this time, the support platform 2 is in balance between gravity and magnetic adsorption force; and when the steel structure column itself is inclined, then the gravity received by the support platform 2 is greater than the magnetic adsorption force, then the support platform 2 will deflect and the magnetic adsorption surface will separate; at this time, the circular bubble level 4 can be used for auxiliary judgment.

[0028] Embodiment 2

[0029] A steel structure column installation measurement and correction structure proposed by the present utility model, different from Embodiment 1, the movable platform 3 includes a support portion 31 and a sliding portion 34; the support portion 31 is arranged on the top of the sliding portion 34; the support portion 31 is higher than the support platform 2 and does not contact the upper surface of the support platform 2. Both sides of the sliding portion 34 are grooved for sliding in cooperation with the guide rails 21; a positioning shaft 36 and a clamping member 35 are arranged on the sliding portion 34; an elastic member is arranged on the positioning shaft 36;

[0030] During the process of the sliding portion 34 sliding along the guide rails 21, the clamping member 35 is located below the guide rails 21, clings to the lower surface of the guide rails 21 and keeps sliding; when encountering the positioning notch 22, under the action of the elastic member, the clamping member 35 moves upward and enters the positioning notch 22 to make the sliding portion 34 clamped and positioned with the positioning notch 22 on the guide rails 21. A button 32 is arranged on the support portion 31; the button 32 abuts against the positioning shaft 36; when the button 32 is pressed downward, the positioning shaft 36 moves downward and squeezes the elastic member to keep it contracted, and at the same time the clamping member 35 moves downward and moves out from the positioning notch 22.

[0031] When installing anchor points or anchor parts on the surface of a steel structure column and it is impossible to directly measure the verticality by the magnetic adsorption method of the installation column 1; then fix the laser level through the installation base 33; at this time, pull out the support platform 2 outward so that the guide column 12 and the B side wall of the plug-in part 23 maintain magnetic attraction; move the movable platform 3 to stop at the first positioning notch 22. At this time, the laser level projects a ray upward and measures the distance L1. After determining the laser positioning point; move the movable platform 3 to the second positioning notch 22, adjust the ray of the laser level to the positioning point of the first time, and measure the distance L2; at this time, the moving distance in the horizontal direction is a fixed value d. According to the Pythagorean theorem; L1 2 +d 2 = L2 2 , if there is a deviation between the measured value and the calculated value of L2, it is determined that there is a problem with the installation inclination of the steel structure column according to the size of the deviation. At this time, just correct the installation again.

[0032] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to this. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
