Fig. 3 is a three-dimensional view showing that the adjustable edge structure of the top and bottom of the creative building formwork is applied to the bottom. When it is applied to the bottom of the building formwork, the strip track hole 102 of the metal formwork element 101 has adjustable The feature of height is that the fixed screw element 201 is the axis and the screw head 202 is against the side of the strip track hole. The metal formwork element 101 and the metal boundary formwork element 401 are both flat plate structures, so that the metal formwork element 101 can be along the metal The boundary template element 401 slides and translates to a desired height, and the metal template element 101 can lean against the floor at the bottom. In addition, referring to Figure 4, it shows the three-dimensional view of the adjustable edge-reducing structure of the top and bottom of the creative building formwork applied to the top. In the figure, the metal formwork element 101 is a flat structure, and the fixing screw element 201 passes through the metal formwork element 101. The strip-shaped track hole 102 enables the metal formwork element 101 to slide and translate to the required height along the metal boundary formwork element 401, wherein the metal formwork element 101 is an L-shaped structure, and the L-shaped structure can provide a plane against the ceiling , which is more conducive to the convenience of explosion-proof grout for grouting operations and demoulding for formwork removal operations.

In order for the review committee to further understand the actual application situation of this creation, give an example of the application field of grouting walls, as shown in Figure 5, which shows the situation diagram of the application of the adjustable edge structure at the top and bottom of the building formwork of this creation on the grouting wall. The middle pouring cement wall 901 is a planar structure, and the reinforcement structure in the pouring cement wall 901 is omitted. First, two opposite metal intermediate formwork elements 501 are assembled, and the metal boundary formwork elements 401 are combined on the top and bottom positions of the metal intermediate formwork elements 501 The bottom metal boundary formwork element 401 stands upright on the floor 601 by means of support screws, and the metal intermediate formwork element 501 and the metal boundary formwork element 401 lean against the floor 601 with supports depending on the situation. Since the floor 601 is uneven and there may be a non-level design of the floor 601, there is a gap between the floor 601 and the metal boundary formwork element 401 at this time, and the metal formwork element 101 of the present invention is used to adjust and block the gap between the floor 601 and the metal boundary formwork element 401 Gaps can save on-site gap measurement and cutting of stuffing molds. The fixing nut element 301 on the fixing screw element 201 is directly screwed, and the metal formwork element 101 is clamped on the metal boundary formwork element 401 . The metal boundary formwork element 401 close to the ceiling is also limited by the inconsistent height of the beams and columns, or the height difference of the corner ceiling, which is suitable for the application of the adjustable edge closing structure at the top and bottom of the building formwork of the present invention, especially for reinforced concrete buildings. It is suitable for the use of the ceiling trim of the present invention. In the figure, when the heights of the ceiling H-shaped steel 701 and the floor plate 801 are inconsistent, it is suitable to adjust the height of the metal formwork element 101 with its L-shaped metal formwork element 101, and directly against the surface of the ceiling H-shaped steel 701 and the floor plate 801, and then The metal formwork element 101 and the metal boundary formwork element 401 are screwed and locked by the fixing screw element 201 and the fixing nut element 301 . Subsequent grouting is used to harden the poured cement wall 901. Since the present invention uses the metal formwork element 101 and the metal boundary formwork element 401, the recovery rate of the metal formwork element 101 and the metal boundary formwork element 401 after demoulding is improved, and The smoothness of the wall surface of the poured cement wall 901 also improves the demoulding efficiency. In addition, the present invention can also be applied to the top and bottom edges of the cylindrical metal formwork. At this time, the metal formwork element 101 is suitable to be arc-shaped, and the arc-shaped metal boundary formwork element 401 conforms to the metal formwork element 101. Slide adjustment on the metal boundary formwork element 401 .

Figure 6 is a perspective view showing the adjustable edge structure of the top and bottom of the creative building formwork applied to the edge of the corner. In the figure, the L-shaped metal formwork element 101 is applied to the corner to cover the edge horizontally. When the metal boundary formwork element When there is a gap between 401 and the metal corner formwork element 1001, and the gap cannot be filled with a general systematic specification metal formwork, it is suitable to be assembled with the adjustable edge-receiving structure of the top and bottom of the building formwork of the present invention. In addition, the side frames of the metal boundary formwork element 401 and the metal corner formwork element 1001 are provided with joint holes with a spacing of about 10-20 cm. When the adjacent joint holes cannot be adjacently paired, the general system cannot be connected The standard metal formwork is in the gap between the metal boundary formwork element 401 and the metal corner formwork element 1001. In this state, it is also suitable for assembly with the adjustable edge-receiving structure at the top and bottom of the building formwork of the present invention. This structure is suitable for the height-adjustable edge finishing at the top and bottom corners. The present invention is an adjustable edge-receiving structure for the top and bottom of the building formwork. The present invention has the characteristics of simplified structure and convenient construction. The on-site construction personnel saves work such as measuring gaps and cutting edge materials, and the on-site construction site can be clean and free. The effect of nailing templates is different from the conventional techniques in the past, and its novelty, progress and practical benefits are unmistakable. Therefore, it can effectively improve the lack of knowledge and has considerable practicability in use.

In view of the above, the specific structure disclosed in this creation embodiment can indeed provide the application of the adjustable edge closing structure on the top and bottom of the building formwork for uneven floors and ceilings. In terms of its overall structure, it has never been seen in similar structures. Among the products, there was no publicity before the application, and sincerity has met the statutory requirements of the patent law, and the invention patent application was filed according to law.
