Description

Technical Field

[0001] The utility model belongs to the technical field of concrete moulds, in particular to a full-size movable grid type concrete top mould stick manufacturing mould. Background Art

[0002] Top formwork bars are needed during the formwork support process at the construction site. Conventional top formwork bars include steel bar top formwork bars and concrete top formwork bars. In the case of insufficient scrap steel bars, projects usually purchase finished concrete top formwork bars to meet construction needs. Some projects also want to make their own concrete top formwork bars by using the remaining ground concrete from each concrete pouring. The mold for homemade top formwork bars is usually supported by a wooden mold. This type of mold has a low turnover rate, a long demoulding time, and a low finished product qualification rate. Its economic benefits are often not as good as those of finished concrete top formwork bars.

[0003] In view of the above defects, the first measure that comes to mind is to replace the wooden mold with steel, which can greatly improve the turnover rate of the mold. However, it also exposes related problems. First, the size of the top mold stick varies. If the steel mold is made one by one according to the size requirements of the top mold stick, the mold production cost is too high. Second, although the mold can be made in batches, the number of single production is limited by the amount of recycled concrete and the number of molds and cannot meet the on-site construction needs. It takes too long for the top mold stick to reach the demoulding strength, and the mold utilization rate is greatly reduced.

[0004] The patent document with application number 201921131960.6 discloses an adjustable mold for concrete top mold bars, including a base frame, a fixed card strip, an adjustable card strip, a back rib, a slide rail and a sliding fixture. The base frame is a rectangular coverless frame. The fixed card strip is fixedly installed on the base frame and is evenly spaced longitudinally. The adjustable card strip is detachably installed on the base frame and is perpendicular to the fixed card strip. The back rib is detachably installed on the base frame and is evenly spaced transversely. The sliding fixture is installed on the outside of the two longitudinal sides of the base frame through the slide rail. This single mold can realize the mass production of concrete top mold bars, solving the problem of low production efficiency of traditional molds; through the setting of adjustable card strips, it can adapt to different wall thicknesses, through the setting of detachable back ribs, it can clamp steel bars of different diameters, and through the setting of sliding fixtures, it can meet the requirements of different steel bar protective layer thicknesses, solving the problem of low versatility and reusability of traditional molds.

[0005] However, in the process of using the above-mentioned mold, it will be difficult to demould the concrete after solidification, and the qualified rate of the top mold stick during the demoulding process is too low. Since the frame, base, and fixed clip of the "adjustable concrete top mold stick mold" are an integral structure, the concrete poured in the spacing groove can only be demoulded by knocking on the back after the concrete is formed. This demoulding method is extremely difficult to remove the top mold stick; and the back rib plug stick designed therein will bond with the concrete between the grooves, making the demoulding process more difficult, and the final yield is less than 30%. In addition, when using the above-mentioned mold, the strength of the concrete in the mold must reach more than 70% before the demoulding operation can be performed, which takes a long time to occupy the mold and requires more than 3 days of mold maintenance, otherwise the top mold stick will be completely damaged during the demoulding process. Finally, the overall weight of the above-mentioned mold is heavy, and the time required for mold cleaning is long, which limits production efficiency and increases labor costs invisibly.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-5 As shown, the utility model provides a full-size movable grid type concrete top mold rod manufacturing mold, including a frame bottom bracket 1, a transverse movable baffle 2, a connecting shaft 3, a longitudinal adjustable baffle 4 and a groove pressing rod 6; the frame bottom bracket 1 is a coverless rectangular parallelepiped structure, including a bottom plate 11 and a side plate 12, and a group of opposite side plates 12 have corresponding slots on the top; the transverse movable baffles 2 are arranged at intervals, and their plate bodies are clamped in the slots of the side plates 12, and their two ends extend to the outside of the frame bottom bracket 1; the connecting shaft 3 is movably inserted at the end of the transverse movable baffle 2, and its two ends are connected to the frame bottom bracket 1. The frame base support 1 is connected so that the transverse movable baffle 2 can rotate with the connecting shaft 3 as the center, which is convenient for demoulding and cleaning the mold; a slot is set at the bottom of the longitudinal adjustable baffle 4 corresponding to the transverse movable baffle 2, and is clamped on the transverse movable baffle 2 through the slot. The longitudinal adjustable baffle 4 moves along the length direction of the transverse movable baffle 2 to achieve the length adjustment of the top mold rod; the groove pressing rod 6 is set parallel to the longitudinal adjustable baffle 4, and its bottom is grooved corresponding to the transverse movable baffle 2. The groove pressing rod 6 is used to press a groove out of the initially solidified top mold rod, which is convenient for fixing the top mold rod on the steel bar.

[0028] The side panels 12 are galvanized steel plates with a height of 50 mm, a length of 600 mm, and a thickness of 2 mm. Four side panels 12 are welded together to form a rectangular structure. Preferably, the spacing of the card slots is 30 mm, the width is 3 mm, and the depth is 30 mm. The four corners of the rectangular structure enclosed by the side panels 12 are welded with triangular steel plates, and the bottom plate 11 is arranged in the rectangular structure and placed on the triangular steel plates. The bottom plate 11 is a wooden board to reduce the overall weight of the mold. The bottom plate 11 and the side panels 12 are detachably connected to facilitate cleaning after use. Graduation lines are set on the side panels 12 parallel to the transverse movable baffle 2 to facilitate the determination of the position of the longitudinal adjustable baffle 4.

[0029] The transverse movable baffle 2 is a 2mm thick galvanized steel plate, and its bottom is in contact with the bottom plate 11. All transverse movable baffles 2 are connected in series through the connecting shaft 3. When removing the mold, first remove the longitudinal adjustable baffle 4, and then rotate the transverse movable baffle 2 to take out the top mold rod. Since both the transverse movable baffle 2 and the longitudinal adjustable baffle 4 are detachable, the problem that the conventional concrete top mold rod mold requires the concrete strength to reach 70%-100% before demolding can be solved. The present application can be demolded when the top mold rod is finally set, that is, within 8-12 hours, thereby increasing the turnover frequency of the mold.
