The utility model adopts the above technical scheme, and compared with the prior art, it has the following advantages:

1. The cross support structure is formed by the vertical support rod and the horizontal support rod. By turning the first adjustment nut on the vertical support rod, the distance between the upper and lower first top plates can be adjusted to adapt to the height of the door and window openings. By rotating the horizontal support The second adjusting nut on the rod can adjust the distance between the left and right second top plates to adapt to the width of the door and window openings, so that the support frame can be conveniently supported in various sizes of door and window openings, which has strong versatility and is convenient reuse.

2. Use two first top plates, two second top plates and four right-angle top plates to form a variable-sized rectangular support frame, which can not only stably support the middle part of the formwork, but also effectively support the formwork at the right angles of the door and window openings (i.e. formwork end), which can prevent local deformation of the formwork, thus ensuring the beautiful and standardized shape of the formed door and window openings.

detailed description

The specific implementation of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, a door and window opening template support frame includes a vertical support rod 10 and a lateral support rod 20, and the vertical support rod 10 and the lateral support rod 20 are fixedly connected together in a cross state, wherein, The upper and lower ends of the vertical support rod 10 are respectively provided with first inner cavities 11 along its length direction, and first screw rods 13 are respectively slidingly arranged in the two first inner cavities 11, and the outer ends of the two first screw rods 13 are fixedly connected. There is a first top plate 14, and the outer parts of the upper and lower ends of the vertical support rod 10 are respectively rotatably connected with a first adjusting nut 12, and the first adjusting nut 12 is threadedly connected with the first screw rod 13, and the first screw rod can be made to rotate by rotating the first adjusting nut 12. 13 slides inwardly or outwardly along the first inner cavity 11 to adjust the distance between the two first top plates 14 .

The left and right ends of the transverse support rod 20 are respectively provided with a second inner cavity 21 along its length direction, and second screw rods 23 are respectively slidingly arranged in the two second inner cavities 21, and the outer ends of the two second screw rods 23 are fixedly connected with The second top plate 24, the outside of the left and right ends of the lateral support rod 20 are respectively rotatably connected with a second adjusting nut 22, and the second adjusting nut 22 is threadedly connected with the second screw rod 23. By rotating the second adjusting nut 22, the second screw rod 23 can be moved along the The second inner cavity 21 slides inward or outward, thereby adjusting the distance between the two second top plates 24 .
