Fig. 1 is the utility model relates to a size adjustable reserves entrance to a cave template's structural schematic, this size adjustable reserves entrance to a cave template and is applicable to the reservation entrance to a cave of square.

As shown in fig. 1, the size-adjustable reserved hole formwork in this embodiment includes a supporting frame 1, four first formworks 2, four second formworks 3 and eight connecting sleeves 4. Wherein support frame 1 is equipped with eight supporting legs that are "rice" style of calligraphy and distribute, is 45 contained angles between each supporting leg, and all is equipped with first external screw thread on every supporting leg.

The first template 2 is of a flat plate type structure, a first support rod 5 perpendicular to the surface of the first template 2 is arranged at the center of one side of the first template close to the support frame 1, a second external thread is arranged on the first support rod 5, and the rotation direction of the second external thread is opposite to that of the first external thread, namely the second external thread and the first external thread are respectively a positive rotation thread and a negative rotation thread. And a positive and negative screw thread matched with the first thread and the second thread is arranged in the connecting sleeve 4. The four first formworks 2 are provided on four support legs opposed to each other, i.e., four support legs up, down, left, and right as shown in fig. 1, via the above-described connecting sleeves 4. The end of the first stay bar 5 is connected with one end of the connecting sleeve 4 through screw threads, and the other end of the connecting sleeve 4 is sleeved on one supporting leg of the supporting frame 1 through screw threads. When the template adjusting device is used, the support frame 1 and the first template 2 cannot rotate, and the distance between the first template 2 and the support frame 1 can be adjusted only by rotating the connecting sleeve 4.

The second template 3 is an L-shaped folded plate structure, a second support rod 6 is fixedly connected to the center of the inner side (the side close to the support frame 1) of the second template, an included angle of 45 degrees is formed between the second support rod 6 and the plate surface of the second template 3, and second external threads are also arranged on the second support rod 6. The four second formworks 3 are provided on four support legs facing each other, i.e., four support legs inclined as shown in fig. 1, via the above-described connecting sleeves 4. The end of the second stay bar 6 is connected with one end of the connecting sleeve 4 through screw threads, and the other end of the connecting sleeve 4 is sleeved on one supporting leg of the supporting frame 1 through screw threads. When the template adjusting device is used, the support frame 1 and the second template 3 cannot rotate, and the distance between the second template 3 and the support frame 1 can be adjusted only by rotating the connecting sleeve 4.

The distance between the first template 2, the second template 3 and the support frame 1 is adjusted by rotating the connecting sleeve 4, and the overall dimension of the whole reserved opening template can be adjusted.

As shown in fig. 1, the second form 3 is disposed inside the first form 2, that is, the outer side surface of the second form 3 abuts against the inner side surface of the first form 2, and when the first form 2 and the second form 3 are moved outward, the first form 2 and the second form 3 always form a square form frame.

In addition, a graduated scale is arranged on the side end face of the second template 3, the graduation of the graduated scale increases from the top angle of the second template 3 to two ends, and the initial graduation of the graduated scale is half of the length of the first template 2. Referring to fig. 2, in this embodiment, the length of the first template 2 is 400mm, and the start scale of the scale is 200. In use, the length of the reserved hole template is obtained by multiplying the scale at the intersection of the end part of the first template 2 and the second template 3 by two.

In this embodiment, the second template 3 is disposed inside the first template 2, and in other embodiments, the positions of the second template and the first template may be changed, and after the change, the scale needs to be disposed on the first template 2, and the start scale is disposed at the center of the side end surface of the first template 2, the scale increases from the center to both ends, and the value of the start scale is the width of the second template 3.

In addition, in this embodiment, the plate thicknesses of the first die plate 2 and the second die plate 3 are both 2 mm. In order to enhance the strength of the surfaces of the first template 2 and the second template 3, a stiffening rib is arranged on the inner side surface of the second template 3, and the stiffening rib can be a rectangular square pipe and is fixed on the inner side surface of the second template 3 in a welding mode. The size-adjustable reserved opening template is simple in structure, raw materials are all common materials for building construction sites, and manufacturing cost is low.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
