Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0022] Embodiment one:

[0023] Please refer to Figures 2-3 The utility model discloses a special tool for fixing super high performance concrete UHPC plate, including

[0024] Cross rod 1 is provided with two, and the outside wall of cross rod 1 is provided with scale line 2;

[0025] Two vertical positioning rods 3 are symmetrically arranged in the inside of the two ends of cross rod 1 and are slidably arranged along the axial direction;

[0026] Fixed plate 4 is fixedly installed in the middle part of two cross rods 1.

[0027] The inside of cross rod 1 is provided with first sliding slot and second sliding slot, and the first sliding slot and the second sliding slot are communicatively arranged, the inside of first sliding slot is slidably provided with sliding plate 5, the upper end of vertical positioning rod 3 is slidably arranged in second sliding slot, and sliding plate 5 is fixedly installed on the outer wall of the upper end of vertical positioning rod 3.

[0028] The first sliding slot and the second sliding slot are combined to form a cross structure.

[0029] The top wall of vertical positioning rod 3 is provided with an internally threaded groove, and a screw rod 6 is movably connected in the internally threaded groove, and a positioning cap column 7 is fixedly installed on the upper end of the screw rod 6.

[0030] One end of cross rod 1 is fixedly installed with handle 8.

[0031] The outer wall of the end of handle 8 is sleeved with rubber sleeve 9.

[0032] Specifically, the handle 8 and the rubber sleeve 9 are arranged to facilitate holding the device.

[0033] As can be seen from the above, two cross rods 1 are arranged, two vertical positioning rods 3 are symmetrically and slidably arranged on one cross rod 1, and when in use, the two vertical positioning rods 3 are placed in the beam formwork and located on the two sides of the beam reinforcement cage;

[0034] When in use, the scale line 2 is arranged on the cross rod 1, and the position of the two vertical positioning rods 3 in the axial direction of the cross rod 1 is adjusted by sliding, so that the distance between the side wall of the vertical positioning rod 3 and the inner wall of the beam formwork is measured;

[0035] After adjusting the control distance, the personnel once again utilize the characteristic that the positioning cap 7 is fixedly installed on the upper end of the screw 6 to further rotate the positioning cap 7 and the screw 6, so that the lower end of the positioning cap 7 contacts and presses against the upper wall of the horizontal bar 1, thereby fixing the position of the vertical positioning rod 3;

[0036] After fixing, personnel can align one end of the UHPC board with the side wall of the vertical positioning rod 3 (at this time, the bottom wall of the UHPC board is in contact with the upper wall of the beam formwork for support).

According to the structural requirements, the UHPC board extends into the component by 8mm to 12mm (the end of the UHPC board needs to enter the beam concrete to a certain depth), and its specific depth is determined by the thickness of the beam's protective layer.

[0039] The length of the fixing plate 4 is 180mm (the minimum beam width is 200mm), and the design length of the fixing plate 4 needs to be less than the beam width;

[0040] In actual operation, the personnel insert the vertical positioning rod 3 into the beam formwork and place it on both sides of the beam reinforcement frame. Based on the thickness of the beam's protective layer, the depth to which the end of the UHPC board needs to enter the concrete beam is determined. The position of the vertical positioning rod 3 is then adjusted by sliding it at a set distance and positioned by the positioning cap 7. After positioning, the personnel align one end of the UHPC board with the side wall of the vertical positioning rod 3. The above work is repeated to install all the UHPC boards. After that, concrete is poured. The overall appearance quality is not affected after pouring.
