Description

Device capable of rapidly detecting strength of existing raw soil wall

Technical Field

The utility model belongs to the building structure field is a but device of short-term test existing immature soil wall intensity.

Background

The raw soil building is convenient for local materials, has low manufacturing cost and good heat insulation performance, is widely applied in vast rural areas and is deeply popular with local people. Has less environmental pollution and little influence on the local environment during and after the demolition. With the popularity of rural tourism in recent years, the native building is popular with travelers, accords with the sustainable development concept, and has wide development prospect.

However, the construction quality cannot be detected in the traditional construction process, and the control is carried out by the experience of a craftsman. The strength of the built raw soil house cannot be measured by a uniform method. The strength index of the repaired and repaired old house can not be obtained. These leave a safety hazard for future development. According to the investigation results of earthquake disasters, the damage rate of the houses of the raw soil buildings is very serious when the houses suffer from earthquakes, and the raw soil walls have low strength and can crack or collapse. And some load-bearing raw soil walls with good construction quality and high strength are basically intact except cracks at some parts. This means that if the strength index of each wall can be measured and repaired or reinforced according to specific conditions, a firm foundation is laid for the safety of the user's housing. Therefore, it is of great significance to design a device for detecting the strength of the built raw soil wall.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a device capable of rapidly detecting the strength of an existing earth wall is shown, and comprises a bottom plate 8, a rod member 2, a counterweight 3, a level gauge 4, a metal striker 5, a striker 6, a rubber pad 7 and a limiting column 10, wherein a hinged part 9 is arranged on one side of the upper end part of the bottom plate 8, a hinged end 1 of the rod member 2 is connected to the hinged part 9 through a bolt, the rod member 2 is connected with the counterweight 3 in a sliding manner, the counterweight 3 is provided with the level gauge 4, and the bottom of the rod member 2 is provided with the metal striker 5; a striker mechanism (a striker 6, a rubber pad 7 and a limit column 10) is arranged at the bottom end side part of the bottom plate 8, and the length of the rod 2 corresponds to that of the bottom plate 8, so that the metal striker 5 can correspond to the striker mechanism.

As shown in fig. 2, the rod 2 is provided with scales to facilitate setting of specific numerical values. The metal striker 5 is arranged at the lower end of the rod member 2 and is a rectangular block, and the plane part of the rectangular block corresponds to the striker of the striker mechanism.

As shown in fig. 3, the balance weight 3 is a cylindrical member with a through hole, and a level 4 is provided on one side of the cylinder. The level is embedded in the counterweight 3 so that the angle of the rod at each pull-up remains the same.
