Abstract
The invention belongs to the field of building engineering quality detection, and particularly relates to a dial indicator mounting base for a floor static load test.
Description
Technical Field
The invention belongs to the field of quality detection of constructional engineering, and particularly relates to a dial indicator mounting seat for a floor static load test.
Background
A method for detecting the strength of a floor is used for a floor static load test, the existing method is to manually build a scaffold, a dial indicator is installed at the top end of the scaffold, a measuring head of the dial indicator is abutted to the lower portion of a floor, the static load is applied to the floor, the deformation of the floor is read through the dial indicator, whether the strength of the floor is qualified or not is judged according to the deformation, the building and carrying workload of the scaffold in the existing mode is increased, the scaffold needs to be installed, and the operation is inconvenient.
Disclosure of Invention
The invention provides a dial indicator mounting base for a floor static load test, which aims to improve the floor static load test efficiency.
The invention relates to a dial indicator mounting seat for a floor static load test, which comprises a base, a telescopic rod arranged on the base and a clamping frame arranged at the top end of the telescopic rod, wherein the clamping frame is used for mounting a dial indicator.
The dial indicator mounting support is arranged on the ground and is positioned under a floor slab to be detected, the dial indicator with a signal output port is mounted on the clamping frame, the dial indicator is connected to a digital display meter or a computer through a data line, the telescopic rod is pulled out until a contact of the dial indicator is in contact with the floor slab, the initial value of the dial indicator is recorded, then a static load is applied to the floor slab, the measured value of the dial indicator is recorded, and the deformation of the floor slab in the static load test is obtained by subtracting the initial value from the measured value.
In order to avoid the influence of rough and uneven floor slabs on measurement, a telescopic base plate is arranged at the top end of the telescopic rod and comprises a base plate and an elastic mechanism positioned between the base plate and the top end of the telescopic rod, the base plate is positioned right above the dial indicator, when the telescopic base plate is expanded and contracted, the base plate is higher than a contact of the dial indicator, and when the telescopic base plate is compressed, the base plate is pressed on the contact of the dial indicator; when the device is used, the telescopic rod is pulled out until the base plate is in contact with the floor slab and is compressed downwards until the base plate is in contact with the dial indicator contact, so that the base plate is arranged between the dial indicator contact and the floor slab, the contact is prevented from being in direct contact with the rough and uneven floor slab, the dial indicator contact is effectively protected, the contact surface of the base plate and the floor slab is large, a measuring point is not influenced by the rough surface of the floor slab, and the measuring precision is improved.
The dial indicator mounting seat for the floor static load test comprises a base, a telescopic rod arranged on the base and a clamping frame arranged at the top end of the telescopic rod, wherein the clamping frame is used for mounting the dial indicator.
Drawings
FIG. 1 is a block diagram of an embodiment of a dial gauge mounting base for floor static load testing according to the present invention.
Fig. 2 is a left side view of fig. 1.
Fig. 3 is an enlarged view of the region M in fig. 2.
In the figure: 1. The device comprises a base, 2, a telescopic rod, 3, a top plate, 4, a clamping frame, 5, a base plate, 6, a spring, 7, a guide sleeve, 8, a dial indicator, 9, a notebook computer, 10, a guide rod, 11 and an adjustable bolt.
Detailed Description
Fig. 1 to 3 show an embodiment of a dial indicator mounting base for a floor static load test, which comprises a base 1, an expansion link 2 mounted on the base 1, a top plate 3 mounted on the top end of the expansion link 2, and a clamping frame 4 mounted on the top plate 3, wherein a dial indicator 8 is mounted on the clamping frame, an adjustable bolt 11 is arranged on the lower part of the base 1, the adjustable bolt 11 is used for leveling the base 1, the dial indicator 8 is a cis-feng gold-brand dial indicator with a data interface, and the data interface of the dial indicator 8 is connected with a notebook computer 9 through a data line.
Install flexible backing plate mechanism on roof 3, be provided with flexible backing plate on the top of telescopic link, flexible backing plate includes backing plate 5 and is located the elastic mechanism between backing plate 5 and the roof 3, elastic mechanism is including installing four guide pin bushings 7 on roof 3 upper portion and installing four guide arms 10 in the 5 lower parts of backing plate, but every guide arm 10 corresponds plug connection in a guide pin bushing 7, and the cover is equipped with a pressure spring on every guide arm 10, and backing plate 5 supports on the pressure spring, and backing plate 5 is located the percentage table directly over, when flexible backing plate stretches out and draws back, and backing plate 5 is higher than the percentage table contact, and when flexible backing plate compressed, backing plate 5 pressed on the percentage table contact.
When the dial indicator mounting support is used, the dial indicator mounting support is placed on the ground and is positioned under a floor to be detected, the telescopic rod 2 is pulled out until the base plate 5 contacts the floor, the telescopic rod 2 is continuously pulled out upwards, meanwhile, the measured value of the dial indicator 8 collected by the notebook computer 9 is observed until the dial indicator 8 has a measured value of 0.5-2 mm, the measured value is used as an initial value, at the moment, the base plate is compressed to be in contact with a dial indicator contact and has a certain prepressing amount, the initial value of the dial indicator is recorded, then, a static load is applied to the floor, the measured value of the dial indicator is recorded, and the measured value subtracts the initial value to obtain the floor deformation amount of a static load test.
