Detailed Description
With reference to the attached drawings. The embodiment of the splicing and sewing template of the arch dam is described in detail as follows:
an arch dam splicing template comprises a splicing template panel 1, a hook head device 2, a large-size nut 3, a base plate 4 and a cross beam 5.
The eave tile device 2 is connected with a round hole 1-2 of a left rib plate of a splicing template panel through a front-end steel bar hook 2-1 in a matched mode, a large nut 3 is arranged on a straight screw rod 2-2 of the eave tile device, a backing plate 4 is arranged on the eave tile device and below the large nut, and the backing plate 4 is pressed and attached to a cross beam 5 through the nut 3.
The splicing template panel is provided with a rectangular plane panel 1-1, and one side of the rectangular plane panel 1-1 without the rib plate is inverted with a slope angle. One side of the rectangular plane panel 1-1 is provided with a left rib plate and a right rib plate.
The left rib plate 1-2 is provided with single-row round holes at equal intervals, the size of the intervals is matched with the intervals of the cross beams, and holes in the frame meet the requirement of hooking of the hook head device under any condition when the rectangular plane panel 1-1 rotates.
The right rib plate 1-3 has no hole and the height is larger than the height of the left rib plate 1-2, and the transverse rib plate 1-4 is arranged between the left rib plate and the right rib plate at a certain interval.
The hook head device 2 is composed of a steel bar hook 2-1 and a straight screw rod 2-2, and the steel bar hook 2-1 and the straight screw rod 2-2 are connected through welding.
The backing plate 4 is of a middle protruding structure, the length of the backing plate is the same as the width of the cross beam, and a through round hole is formed in the center of the middle protruding part.
The beam 5 is provided with channel steel 5-1 and channel steel 5-1 webs which are equidistantly provided with double rows of round holes, sleeves 5-2 are arranged between the channel steels, and a screw 5-3 penetrates through the round holes of the channel steels and the sleeves 5-2 and then is connected and assembled into a whole through nuts 5-4. With the detachable design, when the assembling and mounting position of the sleeve 5-2 interferes with the hook head device 2, the sleeve and the bolt can be detached and moved to a non-interfering hole position near the channel steel for re-mounting.
When in use, the method is implemented according to the following steps:
1) the beam 5 is temporarily fixed with the water stop template 6 and the cantilever template 7,
2) the spliced template panels 1 are combined and designed according to the structural size of the trapezoidal gap, and the spliced template panels 1 are rotated to form angles with each other, and the angles among the spliced template panels can be different.
3) According to design requirements, each piece of abutted formwork panel 1 presses one side of a rectangular plane panel 1-1 without a rib plate on a water stop formwork 6 or a rectangular plane panel 1-1 through a hook device 2, a large nut 3 and a base plate 4, and a right rib plate 1-3 of the abutted formwork panel is pressed on a channel steel flange plate of a matched cross beam 5.
4) The cross beam 5 is connected with the anchoring point through a brace system.
After the steps are completed, the arch dam joint template can meet the concrete pouring construction.
The arch dam abutted seam template is a steel panel, is convenient to manufacture and can be used repeatedly. Through the lap-joint cooperation of two or polylith piece template, can satisfy between arch dam transversal joint stagnant water template and the cantilever template the trapezoidal gap region use of not unidimensional.
