Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The utility model provides an adjustable lintel formwork device, which comprises a pair of support platforms 1 arranged in parallel as shown in figures 1 and 2, wherein an interval adjusting mechanism is connected between the two support platforms 1, and strip-shaped width adjusting holes 5 are horizontally formed in the two ends of the table top of each support platform 1 along the direction vertical to the interval adjusting mechanism. The interval adjustment mechanism comprises a coarse adjustment pipe 2 which is horizontally connected with one of the two support racks 1 and leans on one side, a coarse adjustment screw rod 3 is sleeved on the other end of the coarse adjustment pipe 2 through coaxial threads, a fine adjustment turn buckle 4 is fixedly connected with the other end of the coarse adjustment screw rod 3 coaxially, and the other end of the fine adjustment turn buckle 4 is connected with the other side of the two support racks 1 and leans on one side. The side form that has the adjustable width formula is erect jointly in the top of two support rack 1, and the side form includes two L shape templates 6 that set up mutually in the back of the body mutually, and every template 6 is all erect in two support rack 1 tops perpendicularly, and the position that the both ends of every template 6 correspond below width control hole 5 has all passed adjusting bolt 7, and the slide opening 8 has all been seted up along length direction in the one end of every template 6 through adjusting bolt 7's position.
