For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0039] Reference Figure 1-4 The present embodiment provides a device for quickly positioning and installing armor seams, which includes a portal support frame 1, a lifting bracket 2, a height adjustment screw 3, a width stopper 4 and a width adjustment screw 5. The lifting bracket 2 is located inside the portal support frame 1 and is connected to the portal support frame 1 through the height adjustment screw 3; two sets of width stoppers 4 are correspondingly arranged in the lifting bracket 2, and the two sets of width stoppers 4 are respectively installed with width adjustment screws 5, and the two sets of width adjustment screws 5 can be close to or away from each other.

[0040] 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, lay the floor steel mesh, and on one side of the layout position of the armor seam 12, embed multiple vertical supporting short bars along the length direction of the armor seam 12; use the theodolite, infrared level and wire marking to position and lay out the armor seam 12 before installation. The nylon (or steel wire) wire used for positioning must be fixed and tightened, and the elevation of the wire must be adjusted to about 10mm above the surface of the armor seam 12, as the control line for positioning and measuring the straightness and horizontality of the armor seam 12; place two sets of this device above the positioned nylon wire, and the gantry frame crosses the nylon wire, with the center basically aligned with the nylon wire. Place the armor seam 12 on two lifting brackets 2, align with the center of the lifting bracket 2, and use a tape measure, a ruler, etc. for reference. The armor seam 12 is initially positioned by 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, and the height of the lifting bracket 2 and the armor seam 12 is adjusted by adjusting the height of the screw 3, and 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 bars on the vertical support short bars, weld the two ends of the oblique support short bars 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 bars are not set, remove the vertical support short bars and the oblique support short bars, and pour the floor on the other side.

[0041] Before installing the short oblique support bars, the device can provide vertical support and lateral clamping for the armor seam 12. The height and position of the armor seam 12 along the width direction can be adjusted by the height adjustment screw 3 and the width adjustment screw 5, so as to facilitate the rapid and accurate arrangement and calibration of the armor seam 12 and improve the arrangement efficiency. The device can also reduce the disturbance of the armor seam 12 when installing the short oblique support bars, and prevent the position from being offset and affecting the construction quality.

[0042] Reference Figure 2-3 The portal support frame 1 includes a top beam 1.1, a bottom plate 1.3 and a triangular support frame 1.4. A set of triangular supports 1.4 is provided at each end of the top beam 1.1. The bottom plate 1.3 is fixedly arranged at the bottom of the triangular support frame 1.4 to increase the contact area with the ground and improve the support stability. The triangular support frame 1.4 is provided with two diagonal supports and one vertical support. The top ends of the three are connected and the bottom ends are respectively connected to the bottom plate 1.3 to form a triangular stable support structure with the bottom plate 1.3, further improving the support stability.

[0043] Among them, 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, 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 part 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 with the height adjustment screw 3, and the other is slidably connected with the height adjustment screw 3 and limited by the limit block 7. For example, the top beam 1.1 can be threadedly connected with the height adjustment screw 3, and the first rotary handle 6 can be set at the top end of the height adjustment screw 3, and 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, so as to prevent the lifting bracket 2 from falling, and when the first rotary handle 6 is rotated, the height adjustment screw 3 and the limit block 7 are raised and lowered, so that the lifting bracket 2 is moved along the height direction.

[0044] In the above technical solution, the first mounting hole 1.2 on the top beam 1.1 can be a threaded hole or a smooth hole. When set as a smooth hole, the first nut 8 can be respectively set on the top and bottom sides of the top beam 1.1, and the first nut 8 is coaxially distributed with the first mounting hole 1.2 and welded and fixed on the top beam 1.1.

[0045] In this embodiment, two groups of height-adjusting screw rods 3 are provided, which are respectively located at the separated sides of the two groups of width-direction blocking rods 4 to ensure the stability of the suspension of the lifting bracket 2 .

[0046] Reference Figure 4The width stopper 4 is provided with a third mounting hole 4.1, and the width adjustment screw 5 is passed through the third mounting hole 4.1 and is threadedly connected to the width stopper 4. When in use, the armor seam 12 is placed between the two sets of width adjustment screws 5, and after the position of the armor seam 12 is accurately adjusted, the width adjustment screw 5 is rotated to gradually approach the armor seam 12, and finally pressed against the armor seam 12 to fix the armor seam 12; when fine-tuning the position of the armor seam 12, the width adjustment screw 5 on one side can be loosened first, and after the armor seam 12 is moved, the width adjustment screw 5 on the other side can be tightened.

[0047] For ease of use, in this embodiment, second rotary handles 9 are respectively provided at the separated ends of the two sets of width-adjusting screws 5; and abutment plates 10 are respectively provided at the proximal ends of the two sets. The size of the abutment plates 10 is larger than the radial size of the width-adjusting screws 5, so as to increase the contact area with the armor gap 12 and reduce the pressure.

[0048] Similar to the configuration of the first mounting hole 1.2, the third mounting hole 4.1 can be a threaded hole or a smooth hole. When set as a smooth hole, a second nut 11 can be respectively set on both sides of the wide-axis baffle rod 4, and the second nut 11 is coaxially distributed with the third mounting hole 4.1 and welded and fixed on the wide-axis baffle rod 4.

[0049] Compared with the prior art, the beneficial effects of the present invention are as follows: the lifting bracket 2 and the width-adjusting screw 5 are used to provide vertical support and lateral clamping for the armor seam 12, and the height and the position of the armor seam 12 along the width direction can be adjusted by the provided height-adjusting screw 3 and the width-adjusting screw 5, so that the armor seam 12 can be arranged and calibrated quickly and accurately, the arrangement efficiency can be improved, and the disturbance to the armor seam 12 caused by the installation of the oblique supporting short ribs can be reduced, so as to prevent the position from being offset and affecting the construction quality.
