Description

Laser type loading position indicator for floor slab load test of house

Technical Field

The utility model relates to a measure utensil equipment technical field, concretely relates to laser formula house floor load test loading position indicator.

Background

After the house is completed or operated for a certain time, the state of the structure is judged by carrying out a load experiment on a house floor slab structure under special conditions, so that a reference basis is provided for the operation management of the house. The floor load experiment is divided into static load experiment and dynamic load experiment, and the static and dynamic states of the structure are judged through the static and dynamic response analysis of the structure. The static load experiment of the bridge is to analyze the deflection and stress response of the structure by loading at a specific position of the floor slab, judge the rigidity of the structure, have higher experiment precision and be widely adopted in the safety judgment of the floor slab. In a static load experiment, the ideal loading position of the load needs to be judged through calculation, and then the ideal loading position is marked at the response position so as to accurately position the load. Higher positioning accuracy is crucial to the final experimental accuracy.

The current common method is to use paint to mark the corresponding position after measuring the position needing loading by using a ruler and a tape measure. This method has a number of disadvantages: firstly, the load experiment requires to go on in the evening that temperature is comparatively stable at present, and the paint of using always is difficult to by accurate observation evening. Even if other auxiliary light sources are adopted, accurate positioning is difficult to help, and meanwhile, the experiment cost is increased. Secondly, a load experiment often has a plurality of load operating modes, and the load positions of different load operating modes may be very close to each other, has increased the load and has discerned the degree of difficulty, leads to the mistake of location. And thirdly, the paint is difficult to remove after the load experiment, and more time and cost are needed to remove the paint in the later period, so that the difficulty is increased for later-period decoration and arrangement.

Therefore provide accurate positioning position for the load fast and do not leave obvious mark on the bridge simultaneously, do not give the artificial difficulty that increases of later stage construction, be the problem that present load experiment urgently needed to be solved.
