[0035] When in use, this device can be arranged in two groups along the length direction of the armor seam 12, respectively used to support and fix the two ends of the armor seam 12. After the foundation construction is completed, the floor steel mesh is laid, and a plurality of vertical supporting short bars are pre-buried along the length direction of the armor seam 12 on one side of the layout position of the armor seam 12; the positioning and laying out of the armor seam 12 before installation are carried out using a theodolite, an infrared level and a wire marker. The nylon (or steel wire) wire used for positioning must be fixed and tightened, and the elevation of the line must be adjusted to about 10 mm above the surface of the armor seam 12, as a control line for the positioning and measurement of the straightness and horizontality of the armor seam 12; two sets of this device are placed above the positioned nylon wire, and the gantry frame crosses the nylon wire, with the center basically aligned with the nylon wire, and the armor seam 12 is placed on the two lifting brackets 2, aligned with the center of the lifting bracket 2, and a tape measure, a ruler, etc. are used as reference The armor seam 12 is initially positioned by using the nylon line elevation and the center line of the armor seam 12; the elevation, center line and straightness are remeasured using a level, an infrared level and a nylon line; the height of the lifting bracket 2 and the armor seam 12 is adjusted by adjusting the screw 3; the side of the armor seam 12 is pressed against the width-adjusting screw 5 to fine-tune and fix its position; after accurate positioning, ensure that the height-adjusting screw 3 and the width-adjusting screw 5 are locked, weld the oblique support short reinforcement to the vertical support short reinforcement, weld the two ends of the oblique support short reinforcement to the floor steel mesh and the armor seam 12 respectively, and remove the device; after pouring the floor on the side where the oblique support short reinforcement is not set, remove the vertical support short reinforcement and the oblique support short reinforcement, and pour the floor on the other side.

[0036] Before installing the short oblique support bars, the device can provide vertical support and horizontal clamping for the armor seam 12. The height and width position of the armor seam 12 can be adjusted by the provided height adjustment screw 3 and width adjustment screw 5, which facilitates the rapid and accurate layout and calibration of the armor seam 12, thereby improving the layout efficiency. The device can also reduce the disturbance caused to the armor seam 12 when installing the short oblique support bars, preventing its position from shifting and affecting the construction quality.

[0037] Reference Attachment Figure 2-3 The portal support 1 comprises a top beam 1.1, a bottom plate 1.3, and triangular supports 1.4. A set of triangular supports 1.4 is mounted at each end of the top beam 1.1. The bottom plate 1.3 is fixed to the bottom of the triangular supports 1.4 to increase the contact area with the ground and improve support stability. The triangular supports 1.4 are equipped with two diagonal supports and one vertical support. The top ends of the three diagonal supports are connected to the bottom plate 1.3, forming a triangular stable support structure with the bottom plate 1.3, further improving support stability.

[0038] The top beam 1.1 is provided with a first mounting hole 1.2, the lifting bracket 2 is provided with a second mounting hole 2.1 corresponding thereto, and the two ends of the height adjustment screw 3 are provided with a first rotary handle 6 and a limit block 7, respectively, and the middle portion is inserted into the first mounting hole 1.2 and the second mounting hole 2.1; one of the top beam 1.1 and the lifting bracket 2 is threadedly connected to the height adjustment screw 3, and the other is slidably connected to the height adjustment screw 3 and limited by the limit block 7. For example, the top beam 1.1 can be threadedly connected to the height adjustment screw 3, and the first rotary handle 6 can be set at the top end of the height adjustment screw 3. The bottom end of the height adjustment screw 3 can be slid through the lifting bracket 2 and then connected to the limit block 7. The outer diameter of the limit block 7 is larger than the inner diameter of the second mounting hole 2.1 to prevent the lifting bracket 2 from falling. When the first rotary handle 6 is rotated, the height adjustment screw 3 and the limit block 7 are raised and lowered, thereby moving the lifting bracket 2 in the height direction.
