AI Technical Summary
In the prior art, the observation of settlement or deformation of the support frame mainly depends on the naked eye observation of the staff, especially when pouring concrete at night, observation is difficult and the safety of the staff is difficult to ensure.
A laser level is used to set up on the four corners of the support frame, and two horizontal and vertical lines are emitted. Marking lines are drawn on the horizontal bar and vertical pole irradiated by the laser level through markers. When the marking lines coincide with the line emitted by the laser level, it means that the support frame has not settled or deformed; otherwise, it means that settlement or deformation has occurred.
Staff can safely observe the settlement or deformation of the support frame body above the foundation pit, which improves the safety and efficiency of observation, especially during night observation, which can still be accurately judged by flashlight irradiation.

Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of building construction, and in particular to a method for observing the settlement and deformation of a support frame body. Background Art
[0002] In a foundation pit, a support frame body is usually provided to support the bottom formwork of a floor slab. The support frame body consists of cross bars, vertical bars and fastener assemblies, and the cross bars and vertical bars are connected by fasteners. The traditional method for checking whether the support frame body has settled is as follows: Workers observe by naked eyes to check whether there is settlement or deformation around the support frame body. This method is not convenient for workers to observe when pouring concrete at night. When workers check under the support frame body, if the support frame body has settled or tilted, the workers are prone to danger. Summary of the Invention
[0003] In order to solve the problems existing in the above-mentioned prior art, the present invention provides a method for observing the settlement and deformation of a support frame body.
[0004] The method for observing the settlement and deformation of the support frame body provided by the present invention adopts the following technical solutions: A method for observing the settlement and deformation of a support frame body includes the following steps: S1. After the support frame body is erected, laser levels are respectively arranged at the four corners of the support frame body, and the laser levels are placed on the top of the foundation pit; S2. The laser level emits two horizontal and vertical lines. Make the horizontal line emitted by the laser level shine on any cross bar of the support frame body, and draw a horizontal line on the cross bar irradiated by the laser level with a marker pen to make a mark, and the horizontal line mark on the cross bar coincides with the horizontal line emitted by the laser level; The vertical line of the laser level shines on one of the vertical bars, and draw a vertical line on the vertical bar with a marker pen, and the vertical line mark on the vertical bar should coincide with the vertical line emitted by the laser level; S3. Workers observe the support frame body above the foundation pit. When the marks on the cross bar and the vertical bar coincide with the two horizontal and vertical lines emitted by the laser level, it indicates that the support frame body has not settled or deformed; When the marked lines on the cross bar and the vertical bar deviate from the two horizontal and vertical lines emitted by the laser level, it indicates that the support frame body has settled or deformed. When observing the support frame body at night, it is necessary to irradiate the support frame body with a flashlight to observe whether the two horizontal and vertical lines emitted by the laser level coincide with the marked lines.
[0005] Compared with the prior art, the present invention has the following technical effects: When workers check the support frame body, they can observe the support frame body 2 above the foundation pit. By observing whether the two horizontal and vertical lines emitted by the laser level coincide with the marked lines on the cross bar and the vertical bar of the support frame body, it can be judged whether the support frame body has settled or deformed.

[0008] The following further describes the present invention in detail with reference to the Figure 1 drawings.
[0009] Referring to Figure 1 , an embodiment of the present invention discloses a method for observing the settlement and deformation of a support frame, including the following steps: S1. After the support frame 2 is erected, laser levels 3 are respectively arranged at the four corners of the support frame 2, and the laser levels 3 are placed on the top surface of the foundation pit 1; the support frame 2 is composed of a plurality of cross bars, vertical bars and fasteners, and the cross bars and vertical bars are connected by fasteners.
[0010] S2. The laser level 3 emits two horizontal and vertical lines, so that the horizontal line of the laser level 3 shines on any cross bar, and a horizontal line is drawn on the cross bar irradiated by the laser level 3 with a marker pen for marking, and the horizontal line mark on the cross bar coincides with the horizontal line emitted by the laser level 3; the vertical line of the laser level 3 shines on one of the vertical bars, and a vertical line is drawn on the vertical bar with a marker pen for marking, and the vertical line mark on the vertical bar should coincide with the vertical line emitted by the laser level 3.
[0011] S3. The staff observes the support frame 2 above the foundation pit 1. When the marks on the cross bar and the vertical bar coincide with the two horizontal and vertical lines emitted by the laser level 3, it indicates that the support frame 2 has no settlement or deformation; when the marked lines on the cross bar and the vertical bar deviate from the two horizontal and vertical lines emitted by the laser level 3, it indicates that the support frame 2 has settlement or deformation. When observing the support frame 2 at night, a flashlight is needed to irradiate the support frame 2 to observe whether the two horizontal and vertical lines emitted by the laser level 3 coincide with the marked lines.
[0012] In the observation method of the present invention, the staff does not need to go to the lower part of the support frame 2 for inspection, and can observe the support frame 2 above the foundation pit. By observing whether the two horizontal and vertical lines emitted by the laser level 3 coincide with the marked lines on the cross bar and the vertical bar of the support frame 2, it can be determined whether the support frame 2 has settlement or deformation.
[0013] The above are all preferred embodiments of the present invention. The protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
