DETAILED DESCRIPTION

[0031] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0032] Example 1

[0033] like Figure 1-4 As shown, this embodiment provides a bridge wet joint construction template, including: a support platform 1 and a bottom template 3, the support platform 1 and the bottom template 3 are connected by a connecting rod 2, the bottom template 3 and the connecting rod 2 are connected by nuts, and it is ensured that the bottom template 3 template can be freely disassembled from the bottom of the connecting rod 2, and the width of the bottom template 3 is preferably 5-10cm to enter the beam body flange plate 6. The support platform 1 is made of lightweight steel material, and the support platform 1 is divided into an upper support platform and a lower support platform. When in use, the legs on both sides of the lower support platform are placed on the left and right flange plates 6 of the wet joint. The upper support platform and the lower support platform are sleeved, and a number of positioning holes are provided on the side. By inserting the pins into different positioning holes, the height of the support platform 1 can be adjusted, and then the connecting rod 2 can be roughly raised and lowered.

[0034] The upper support platform is provided with a connecting rod lifting assembly 4, which includes: a bidirectional screw rod 46, an upper connecting rod assembly and a lower connecting rod assembly. The upper connecting rod assembly includes: a mounting seat 45 and two symmetrically arranged upper connecting rods 44. The mounting seat 45 is hinged to the two upper connecting rods 44 respectively. The mounting seat 45 extends to one side and is then fixed to the top of the connecting rod 2 to stagger the bidirectional screw rod 46 to avoid mutual influence between the two. The lower connecting rod assembly includes: a fixing seat 41 and two symmetrically arranged lower connecting rods 43. The fixing seat 41 is fixed to the top of the upper support platform by bolts and connected to the bottom ends of the two lower connecting rods 43. A slider 43 is provided on the bidirectional screw rod 46, and the bottom end of the upper connecting rod 44 and the upper end of the lower connecting rod 42 are connected to the slider 43. A handle 47 is provided at one end of the bidirectional screw rod 46 to rotate the bidirectional screw rod 46. When the bidirectional screw rod 46 is rotated by the handle 47, the two sliders 43 can be driven to move closer or farther from each other, so that the height of the mounting seat 45 changes, thereby driving the connecting rod 2 to be lifted or lowered.

[0035] Furthermore, a sleeve 5 is sleeved on the connecting rod. After pouring, the sleeve 5 can form a wet joint reserved hole to facilitate subsequent demoulding and hanging of the template. Stop grout grooves 31 are set on both sides of the top of the bottom template 3. The inner edges of the stop grout grooves 31 are at the contact point between the bottom template 3 and the flange plate 6. When the stop grout belt is installed during construction, the bottom template 3 can be tightly combined with the bottom of the beam flange plate 6 on both sides of the wet joint to ensure that the joint is tight, does not deform, and does not leak grout. After demoulding, the wet joint has a smooth linear shape and a flat surface, and is integrated with the left and right flange plates 6 to ensure the overall quality of the wet joint. The problem of grout leakage after the usual wet joint construction is avoided.

[0036] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
