[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0028] like Figure 1-3As shown, the utility model provides a prestressed beam mold reinforcement installation connection structure, including a bottom membrane 1, a side mold 2, a horizontal pull rod 3, an inner support bar 4, and a support and pulling tool 5. The side mold 2 includes a first side panel 21 and a second side panel 22 arranged in parallel, an upper cover plate 23 fixed on the upper part of the first side panel 21 and the second side panel 22, and a support angle iron 24 arranged at the bottom of the first side panel 21 and the second side panel 22. The support and pulling tool 5 is installed between the first side panel 21 and the second side panel 22, and the support and pulling tool 5 includes a control main screw 51, a double-hole connecting nut 52 is screwed on the control main screw 51, and a steel plate 53 is welded on the side of the double-hole connecting nut 52. The end of the steel plate 53 is rotatably connected to a movable connecting plate 54 through a connecting screw 55, and the other end of the movable connecting plate 54 is rotatably connected to the bottom of the first side panel 21 and the second side panel 22 through a connecting screw 55. By controlling the main screw 51 to rotate forward and backward, the double-hole connecting nut 52 is driven to move up and down on the main screw 51, thereby driving the distance between the first side plate 21 and the second side plate 22 to change, and realizing the tightness adjustment of the supporting and pulling tooling, so that the side mold can be disassembled and assembled conveniently and quickly.

[0029] like Figure 1 As shown, an inner support bar 4 is provided between the top of the first side panel 21 and the top of the second side panel 22 to control the size between the side molds.

[0030] like Figure 1 、 4 As shown, horizontal tie rods 3 are spaced apart at the top of the side formwork 2. The horizontal tie rods 3 include a perforated channel steel 31, a first fixing seat 32 fixed to the perforated channel steel 31, and a second fixing seat 33 slidable on the perforated channel steel 31. The horizontal tie rods 3 provide inward support to the upper portion of the side formwork 2, preventing the side formwork 2 from shifting due to concrete pouring.

[0031] like Figure 2 As shown, vertical tie rods 26 are provided at the ends and the middle of the side formwork 2, and horizontal square steel 25 is provided as a pad at the top end of the vertical tie rods 26 located on the upper cover plate 23. The top end of the vertical tie rods 26 passes through the upper cover plate 23 and the horizontal square steel 25 and is fixed by nuts 27. The lower end of the vertical tie rods 26 is fixed to the supporting angle iron 24. The vertical tie rods 26 are used to resist the upward buoyancy generated by the side formwork when pouring concrete.

[0032] like Figure 2 、 5As shown, a plurality of lifting square holes 210 are opened on the upper cover plate 23, and a lifting plate 29 is provided at the position of the lifting square hole 210. The lifting plate 29 is rotatably connected to the screw holes 28 on the upper part of the first side plate 21 and the second side plate 22 through a connecting screw. The lifting plate 29 is used for hook lifting to realize the installation and removal of the mold directly up and down.

[0033] In another embodiment of the present invention, a construction method for reinforcing and installing a connection structure of a prestressed beam mold is provided. A section of the prefabricated beam mold consists of two side molds 2 and a bottom mold 1, and the side mold is placed between the two bottom molds.

[0034] The mold is reinforced by reinforcements consisting of horizontal tie rods 3, internal braces 4, and vertical tie rods 26. The horizontal tie rods 3 are spaced apart at the top of the mold, and the spacing is adjusted by sliding the second fixing base 33 on the perforated channel steel 31 to provide inward support for the upper portion of the side mold, preventing the side mold from shifting due to concrete pouring. The internal braces 4 are spaced apart between the tops of the first side panel 21 and the second side panel 22 to control the distance between the side molds 2. Vertical tie rods 26 are set at the ends and middle of the side mold 2 to resist the upward buoyancy generated by the side mold during concrete pouring.

[0035] A supporting and pulling tooling 5 is provided inside the side mold 2. The supporting and pulling structure operating rod is used to rotate the control main screw 51 of the supporting and pulling tooling 5 clockwise and counterclockwise. The double-hole connecting nut 52 moves up and down on the control main screw 51, pulling the first side plate 21 and the second side plate 22 to move, thereby making the side mold disassembly and assembly convenient and quick.

[0036] There are multiple lifting square holes 210 on the top of the side form 2. A lifting plate 29 is connected to the lifting square holes 210 through connecting screws, which is used to hook and lift the side form 2, so that the form can be installed and removed directly up and down, which greatly reduces the production requirements for the site size and can quickly complete the construction in a small construction area.

[0037] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
