A column detection device for building construction

Abstract

This utility model belongs to the field of column inspection devices, and discloses a column inspection device for building construction. It includes a clamping mechanism comprising a connecting plate, side plates, clamping plates, and an elastic pressure component. The side plates are mounted on the connecting plate, and the elastic pressure component is mounted on the side plates. The clamping plates are connected to the elastic pressure component and are located inside the side plates. A connecting frame has a connecting plate mounted at the end of its side wall, and the connecting frame also has a spacing adjustment component and a handle. A measuring component is mounted on the outer wall of the connecting frame. Through the connection between the elastic pressure component and the clamping plates, the clamping plates can compress the elastic pressure component to move the column when clamping and fixing it. The spacing adjustment component controls the distance between the side plates, allowing the overall position of the clamping plates, elastic pressure component, and side plates to be adjusted according to the column size. This avoids damage caused by excessive compression of the elastic pressure component, improving the applicability of the device for inspecting columns of different sizes.

Description

Technical Field

[0001] This utility model belongs to the technical field of column testing devices, specifically relating to a column testing device for building construction. Background Technology

[0002] Columns are vertical load-bearing components that support the superstructure above the pile foundation. They play a crucial role in load transfer and, to a certain extent, directly determine the stability and reliability of the building. Therefore, after the columns are cast, various parameters need to be tested, among which the testing of the column verticality is particularly important.

[0003] Existing column verticality testing devices are usually fixed to the column by surrounding it on all four sides, and then the verticality of the column is tested by a testing instrument (such as a laser measuring instrument or a plumb bob measuring instrument). However, the surrounding fixing method is cumbersome to install and remove, and the column sizes of different engineering buildings are different. Existing testing devices are also difficult to adapt to columns of different sizes, resulting in poor adaptability and making them unsuitable for practical use. Utility Model Content

[0004] The present invention aims to provide a column inspection device for building construction, so as to solve the problem of poor adaptability of the existing inspection devices mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a column detection device for building construction, comprising...

[0006] The clamping mechanism is provided in two sets. The clamping mechanism includes a connecting plate, a side plate, a clamping plate and an elastic pressure component. The two ends of the connecting plate are movably mounted with side plates. The elastic pressure component is mounted on the side plates. The clamping plate is connected to the elastic pressure component and is located on the inner side of the two side plates.

[0007] The connecting frame has connecting plates installed at the ends of the side walls. The connecting frame is also equipped with a spacing adjustment component and a handle. The spacing adjustment component is used to control the relative position of the two side plates.

[0008] The measuring component is mounted on the outer wall of the connecting frame.

[0009] The principle and effects of this technical solution:

[0010] 1. By connecting the elastic pressure component with the clamping plate, the clamping plates on both sides can make room for the column by compressing the elastic pressure component when clamping and fixing the column. Furthermore, the spacing between the two side plates can be controlled by the spacing adjustment component, so that the position of the clamping plate, the elastic pressure component, and the side plate as a whole can be adjusted according to the size of the column. This avoids damage caused by excessive compression of the elastic pressure component and improves the applicability of the device for testing columns of different sizes.

[0011] 2. The clamping plate and connecting plate of the clamping mechanism are clamped and abutted against the column, thus forming a three-point centering position structure. The connecting frame connects the two clamping mechanisms at the same time, so that the length direction of the connecting frame can be parallel to the axis of the column. At this time, the verticality of the column can be obtained by measuring the tilt angle of the connecting frame through the measuring component.

[0012] The present invention is further configured such that: the elastic pressure assembly includes a push rod, a spring, a limiting head and a mounting bracket, a clearance hole is provided on the side wall of the side plate, the mounting bracket is fixed to the outer wall of the side plate, the push rod is slidably inserted into the mounting bracket, one end of the push rod passes through the clearance hole and is fixed to the clamping plate, the other end of the push rod is fixed to the limiting head, the spring is sleeved on the push rod, and both ends of the spring abut against the clamping plate and the mounting bracket respectively.

[0013] The principle and effect of this technical solution: By limiting and guiding the push rod through the mounting bracket, the push rod can only drive the clamping plate to move along the axial direction of the push rod. Furthermore, the setting of the limiting head prevents the push rod from detaching from the mounting bracket. The setting of the spring and the relief hole, and the fact that the spring abuts against the mounting bracket and the clamping plate through the relief hole, the spring's rebound force can drive the clamping plate to spontaneously move away from the mounting bracket, that is, clamp the column. The spring can also be stored between the relief hole and the mounting bracket. At this time, the clamping plate abuts against the side plate, avoiding excessive compression of the spring by the clamping plate, while occupying less external space.

[0014] The present invention is further configured such that a roller is installed at the end of the clamping plate away from the connecting plate.

[0015] The principle and effect of this technical solution: By setting up rollers, when the clamping plate is clamping the column, the rolling contact between the rollers and the outer wall of the column will cause the clamping plate to move away from the column, thus eliminating the need for manual driving and simplifying the manual operation required for the clamping process.

[0016] The present invention is further configured such that: the spacing adjustment assembly includes a slider, a transmission plate, a control block, a control screw, and a control head; a slider is fixed to the side wall of the side plate; the slider is slidably inserted into the connecting plate; a clearance groove is provided on the side wall of the connecting plate; the transmission plate passes through the clearance groove and is fixed to the slider; the control block is fixed to the side wall of the transmission plate; the control screw is rotatably installed on the connecting frame; the control block is threaded onto the control screw; the control screw is a bidirectional screw; one end of the control screw extends outside the connecting frame and is connected to the control head.

[0017] The principle and effect of this technical solution are as follows: By setting the slider, the side plate can move relative to the connecting plate, thereby changing the maximum and minimum clamping size between the two clamping plates. By setting the transmission plate and the relief groove, the transmission plate can be connected to the slider through the relief groove. Thus, one transmission plate can simultaneously control the synchronous movement of two corresponding upper and lower sliders. The control head drives the control screw to rotate, and the control screw can drive the drive control block to move along the axis of the control screw (because the transmission plate and the slider are fixed, the transmission plate and the control block cannot rotate). Thus, the movement of the slider can be indirectly controlled by the control head to adjust the position of the side plate.

[0018] The present invention is further configured such that the control block and the connecting frame slide against each other.

[0019] The principle and effect of this technical solution: By abutting the control block against the connecting frame, the offset rotational force on the transmission plate can be reduced.

[0020] The present invention is further configured such that: the measuring component includes a plumb line, a weight, and a scale; one end of the plumb line is installed on the upper end of the side wall of the connecting frame, the weight is fixed to the other end of the plumb line, an arc-shaped slide rail is installed on the lower end of the side wall of the connecting frame, the weight moves within the arc-shaped slide rail, and the scale is fixed to the side wall of the arc-shaped slide rail.

[0021] The principle and effect of this technical solution: The weight of the hammer pulls the suspension line straight, while the arc-shaped slide rail restricts the hammer from moving freely. The markings on the dial make it easy for the operator to identify the corresponding scale of the suspension line.

[0022] The present invention is further configured such that the measuring component also includes a horizontal bubble meter, which is mounted on the connecting frame.

[0023] The principle and effect of this technical solution: By setting the horizontal bubble meter, the user can adjust the clamping position of the device according to the offset direction of the horizontal bubble meter, so as to obtain more accurate verticality data when it is adjusted to the optimal position.
