Description
Technical Field
The utility model relates to the technical field of non-breakage detection of a masonry mortar material of a house masonry structure in civil engineering, in particular to a portable automatic stressing device for a mortar penetrometer.
Background
With the development of urban construction in China and the need of updating a large number of existing houses, house detection is used as a main technical means for evaluating the current health condition of the existing houses, and the service volume is increased day by day. Due to historical reasons of building materials and construction science, most houses are currently identified in urban updating processes by adopting a brick-concrete structure system.
In order to determine the material strength of the vertical bearing member of the brick-concrete structure house, the penetration detection mortar strength is currently commonly used in the field of house detection as a nondestructive detection method, and related main current specifications are national standard on-site detection technical Standard for masonry engineering (GB/T50315-2011), industry procedure on penetration method for detecting the compressive strength of masonry mortar (JGJT 136-2017), and local (Shanghai) procedure on commercial masonry mortar detection (DG-TJ 08-2021-2007).
The main method for the penetration method detection comprises the following steps: a working spring is compressed by adopting a penetrometer to load, a measuring nail is penetrated into mortar, and the penetration depth of the measuring nail is converted into the mortar compressive strength through a strength measuring curve according to the correlation between the depth of the measuring nail penetrating through the mortar and the mortar compressive strength. The instrument for detecting the compressive strength of the masonry mortar by the penetration method comprises a penetration type mortar strength detector and a digital penetration depth detection meter.
In order to more correctly and scientifically embody the real material strength of main bearing members of the tested house, repeated operation with larger workload exists when the mortar strength of the solid member is detected through on-site penetration. When the compressive strength of the masonry mortar is detected on site, masonry members or structures with the area not more than 25 square meters are used as one member. When the sampling detection is carried out according to batches, masonry mortar with similar age, same source, same type, same variety and same strength grade is taken as a batch, and the number of sampling detection is not less than 30% and not less than 6 of the total components of the masonry. The test point 16 should be selected for each component to be tested. In order to more accurately evaluate the real compressive strength of each measuring point mortar, the penetration force of the penetrometer should be (800+/-8) N, and the working stroke should be (20.00.10) mm. In order to ensure that enough external force and displacement can be applied according to the standard requirements in each penetration detection, repeated stress application and reset work is needed in each field mortar penetration detection.
The conventional penetrating mortar strength detector can be divided into lever type stress application and nut screwing stress application according to a stress application mode. The two penetrating mortar strength detectors are disclosed in the Chinese patent application No. CN201810886691.8 and No. CN96205094.6, respectively. When the stressing lever is used, the stressing lever is inserted into the outer end of the penetrating rod, and external force is applied to enable the hook to be hung on the hook (the current common method); when the nut is screwed to apply force, the crank is used for screwing the nut until the hook is hung, and then the nut is retracted to the top end of the through rod (the working efficiency is lower, the operation is more complicated, and the nut is rarely used at present).
Because larger external force needs to be applied for each resetting, the labor intensity of field workers is higher, and the safety operation problems such as clamping and the like easily occur in the repeated field operation process.
Therefore, there is a need for improvements and optimizations to existing portable automated force devices for mortar penetrometers that better meet user needs.
