[0012] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0013] Example 1 like Figure 1As shown, a convenient mortar-grouted masonry trench construction base calibration bracket includes: a base 1, a first vertical folding rod 2, a second vertical folding rod 3, and a horizontal folding rod 4; One end of the first vertical folding rod 2 is fixed to the base 1, and the other end of the first vertical folding rod 2 is rotatably connected to one end of the second vertical folding rod 3 through the first rotating connecting shaft 2-4; the other end of the second vertical folding rod 3 is rotatably connected to the horizontal folding rod 4 through the second rotating connecting shaft 3-4.

[0014] like Figure 2-3 As shown, the first vertical folding rod 2 is provided with a first laser slide rail groove 2-1 along the folding rod, and the first laser 2-2 and the first beam splitter 2-3 are slidably arranged in the first laser slide rail groove 2-1; the second vertical folding rod 3 is provided with a second laser slide rail groove 3-1 along the folding rod, and the second laser 3-2 and the second beam splitter 3-3 are slidably arranged in the second laser slide rail groove 3-1. like Figure 4-5 As shown, a transverse laser 4-1 and a transverse beam splitter 4-2 are rotatably mounted at the end of the transverse folding rod 4. The transverse laser 4-1 and the transverse beam splitter 4-2 are rotatably mounted at the end of the transverse folding rod 4 via a third rotating connecting shaft 4-3.

[0015] like Figure 6 As shown, the base 1 is a foldable base, including several rotating folding legs. The rotating folding legs rotate and unfold around a fixed shaft 1-1 to form the base 1. The fixed shaft 1-1 is connected to the first vertical folding rod 2. In this embodiment, there are three foldable bases, namely the first folding leg 1-2, the second folding leg 1-3, and the third folding leg 1-4, which are overlapped and rotated to fold.

[0016] The lateral folding rod 4 is a telescopic rod.

[0017] The vertical folding rod of this invention can also be a telescopic rod.

[0018] The usage process of this utility model's convenient masonry trench construction base calibration bracket is as follows: 1. Configuration of a portable mortar-grouted masonry trench foundation calibration support: (1) Foldable bracket structure Due to the varying working areas provided by the construction sites, and the fact that masonry trenches are mostly located in areas with undulating terrain, resulting in uncertain working space, different trench sizes, and different required inclination angles for the sidewalls of the masonry trenches, stainless steel foldable rods with tight connections, flexible extension and retraction, compact size, and sturdiness are selected as the folding rods.

[0019] (2) Straightness testing device Due to the wide range of nature and construction sites involved in mortar-grouted masonry projects, it is difficult to ensure the straightness of the top surface of most mortar-grouted masonry structures. Since the straightness of the top surface of mortar-grouted masonry channels is an important standard for quality inspection, a leveling device is used to assist in leveling the top surface. The straightness inspection tool should not be too large; a small, lightweight, and adjustable laser, combined with a beam splitter, is used to emit a straight laser beam to solve the problem of straightness of the construction surface.

[0020] (3) Base fixing device Due to operational requirements during construction, the calibration bracket needs to be fixed to the work surface to ensure the standardization and compliance of the masonry trench construction, guaranteeing the accuracy and straightness of the top surface and the required inclination of the side walls. Furthermore, due to the nature of masonry construction, the position of the auxiliary device needs to be frequently changed to proceed with the next section of masonry work. Therefore, the base fixing device uses compact, lightweight, and foldable legs to ensure the stability of the instrument during operation and ease of repositioning.

[0021] (4) Inclination calibration device Due to operational requirements during construction, the inclination angle of the sidewalls needs to be constantly calibrated during the construction of masonry channels. However, due to the characteristics of the masonry construction method, it is impossible to accurately ensure that the sidewall angle of the masonry channel is always at the design standard angle during construction. Therefore, auxiliary equipment that can be calibrated at any time is required to ensure construction quality during the construction of masonry channels. To solve this problem, this calibration device uses a rotatable laser installed at the end of the folded rod to assist in calibrating the masonry operation.

[0022] 2. Installation of auxiliary devices for masonry construction Before installing the equipment, check the performance of all components to ensure that each component is in good condition, without damage, misalignment, or insufficient performance, so as to ensure the normal and effective progress of subsequent construction.

[0023] First, connect and install the folding base to the end of the stainless steel foldable vertical rod, and tighten the bolts to ensure a tight connection between the folding base and the vertical folding rod, so as to ensure the accuracy of the subsequent base adjustment work and the construction work surface during the construction process.

[0024] Subsequently, the three folding legs of the folding base are opened to ensure the stability of the equipment. Next, the vertical folding rods and horizontal telescopic rods are opened, and the sliding laser built into the vertical rod is adjusted to a suitable position, ensuring it is at the required reference plane. Then, the horizontal telescopic rod is extended to a suitable length, and the rotating laser installed at the adjustable end of the rod is used to ensure that the emitted laser surface is at the designed inclination angle of the masonry trench sidewall, guaranteeing that the corresponding reference plane of the masonry trench remains at the laser beam position during subsequent construction. Figure 7 As shown.

[0025] 3. Debugging of auxiliary devices for masonry construction Check the connectivity and operational safety of all installed components, and perform equipment debugging. After debugging, adjust the lateral telescopic rods to different lengths and test the stability of the device under different working space conditions to ensure that the device can operate well during masonry construction without any tilting or slippage of the telescopic rods. Then, turn on the laser power and test the laser beam conversion performance and operational stability at the laser port to ensure that workers can adjust the inclination of the masonry trench sidewalls and the straightness of the top surface according to the laser surface during construction. After successful debugging, extend the telescopic rods to the appropriate length according to the actual project conditions to carry out masonry construction.

[0026] 4. Inspection during the masonry construction process To prevent significant deviations in the straightness of the top surface and the inclination of the side walls during masonry construction, it is crucial to constantly monitor whether the reference surface for the masonry work is aligned with the laser reference surface. If the top surface or side wall slope of the masonry exceeds or fails to reach the reference surface, the corresponding base surface must be adjusted until it reaches the position indicated by the laser surface. This ensures that the inclination deviation of the masonry channel side walls meets the requirements and that the top surface is straight and smooth. Before starting the masonry work, the reference device should be placed in a suitable position so that the corresponding laser surface emitted by the reference device is aligned with the design reference surface from the initial stage of construction. If the reference surface beam becomes skewed during the construction process, adjustments should be made promptly.

[0027] 5. Quality inspection of rebar drilling After the mortar-grouted masonry construction is completed, the laser reference surface is calibrated according to the design drawings. The calibrated laser reference surface is then used to check whether the mortar-grouted masonry base surface meets the design requirements. If the corresponding base surface of the mortar-grouted masonry channel is not at the reference surface shown by the laser surface, the deviation value is recorded, and the inclination deviation and straightness deviation are calculated to check whether they are within the design deviation range, in order to verify the quality of the mortar-grouted masonry construction.

[0028] 6. Retract auxiliary equipment and clean the work surface. After the masonry construction is completed, check the appearance quality of the masonry channel to ensure it meets standards, and check for any signs of skewing or excessive deviation to guarantee construction quality. Simultaneously, check that the device base is in its initial state, without any displacement or skewing, and that the laser surface at the end of the transverse telescopic rod is aligned with the design reference plane. Ensure the entire auxiliary device operates smoothly and effectively. Once everything is verified, turn off the corresponding laser, reduce the transverse telescopic rod to its shortest position, and retract the folding rod, returning the device to its initial folded state. Next, retract the folding base to its minimum position and properly store all auxiliary device components for future use.
