Description

Technical Field

[0001] The utility model belongs to the technical field of concrete making moulds, and in particular relates to a concrete making mould connecting mechanism. Background Art

[0002] A concrete mold is a mold used to make concrete. The most common concrete mold is a steel mold, which is made by connecting multiple steel templates to form a cavity for construction workers to make concrete on site. As a concrete mold, the steel mold must be installed firmly and stably to better ensure the cross-sectional dimensions of the concrete component.

[0003] When assembling this type of concrete mold in the prior art, bolts and nuts are mostly used to connect the connecting strips on the side of the steel formwork. However, since there is no well-designed positioning structure between the two adjacent steel formworks, it takes a certain amount of time to align and position the bolt holes on the connecting strips when actually connecting the two steel formworks, which reduces the overall connection efficiency. At the same time, since the concrete mold is used at a construction site and concrete needs to be poured on site after the concrete mold is connected, some concrete often drips onto the nuts and bolts, which hinders the subsequent disassembly of the concrete mold and reduces the convenience of later disassembly and assembly. For this reason, the present invention needs to improve the existing concrete mold connection mechanism. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example

[0025] See also Figures 1 to 5 , is an embodiment of the present utility model, which provides a technical solution: a concrete mold connection mechanism, including

[0026] The connecting strip 1 is welded and fixed to the side of the steel formwork 2 5, the connecting strip 2 is welded and fixed to the side of the steel formwork 1 6, the bolt groove 7 is opened on the surface of the connecting strip 1 and the connecting strip 2, and the bolt hole 71 is penetrated through the inner wall of the bolt groove 7, and a connecting bolt 81 is provided on the inner side of one of the bolt grooves 7, and the threaded end of the connecting bolt 81 is penetrated into the other bolt groove 7, and the threaded end of the connecting bolt 81 is sleeved with a connecting nut 82, and the connecting strip 1 and the connecting strip 2 are connected and fixed by the connecting bolt 81 and the connecting nut 82. In this way, multiple steel formworks 2 5 and steel formworks 1 6 can be combined and connected together to form a whole formwork, and then the two whole formworks, one in front and one in the back, are connected through an external side formwork to form a rectangular hollow formwork. At this time, concrete can be poured into the hollow formwork for subsequent concrete making. The core of this application lies in the connection between the two adjacent steel formworks, so the working principle of the concrete making mold itself will not be described in detail here;

[0027] and a positioning structure 4 provided between the connecting strip 1 and the connecting strip 2, comprising a positioning block 41 welded and fixed to the side of the connecting strip 1 and a positioning socket 42 provided on the surface of the connecting strip 2. The positioning block 41 is inserted into the positioning socket 42 to play a positioning role when the connecting strip 1 and the connecting strip 2 are connected, facilitating the operator to quickly complete the alignment and positioning of the bolt holes 71 between the connecting strip 1 and the connecting strip 2 when connecting the steel template 2 5 and the steel template 1 6;

[0028] And the protective structure 3 arranged on the surface of connecting strip 1 and connecting strip 2, including a protective cover plate 31. The surfaces of connecting strip 1 and connecting strip 2 are both movably installed with protective cover plates 31, and the protective cover plates 31 cover the bolt groove 7, which can prevent foreign matter from entering the inner side of the bolt groove 7, thereby avoiding the situation where concrete drips on the surface of the connecting bolt 81 and the connecting nut 82 during the concrete pouring process, and providing a guarantee for the operator to separate the connecting strip 1 and connecting strip 2 after the subsequent concrete making is completed.

[0029] Among them, the positioning structure 4 also includes a rubber seat 421 embedded in the side wall of the positioning socket 42, a triangular card block 422 set on the surface of the rubber seat 421, and a rectangular bayonet 411 opened on the surface of the positioning plug 41 on both sides. The triangular card block 422 is embedded in the rectangular bayonet 411, and a groove for the installation of the rubber seat 421 is opened on the side wall of the positioning socket 42, so that the rubber seat 421 can be installed in the groove, so that the rubber seat 421 will not block the normal insertion of the positioning plug 41. The rubber seat 421 and the triangular card block 422 are an integrated structure, and both are made of rubber. The rubber seat 421 is made so that it will undergo elastic deformation when squeezed, so that when the positioning plug 41 is inserted into the positioning hole 42, the triangular clamping block 422 will undergo elastic deformation and be squeezed into the rectangular bayonet 411, thereby playing a certain auxiliary limiting effect, preventing the cleaning and separation between the connecting strip 1 and the connecting strip 2 2, and bringing convenience to the subsequent operators to fix the connecting bolts 81 and the connecting nuts 82. A triangular cavity is provided inside the rubber seat 421, and the position of the triangular cavity corresponds to the triangular clamping block 422, so that the triangular clamping block 422 has sufficient deformation space when squeezed.

[0030] Among them, the protective structure 3 also includes an inner slide groove 33, a spring 34, an inner base plate 35 and a cylindrical side rod 36. The inner slide groove 33 is opened inside the connecting bar 1 and the connecting bar 2 2, and the inner base plate 35 is movably installed in the inner slide groove 33 through the spring 34. The cylindrical side rod 36 is rotatably installed on one side surface of the inner base plate 35, and the end of the cylindrical side rod 36 passes through the outside of the inner slide groove 33 and is fixed to the protective cover plate 31. Under the pushing action of the spring 34, the protective cover plate 31 can stably cover the opening of the bolt groove 7 during the daily concrete making process to prevent the entry of foreign matter from the outside. The protective structure 3 also includes a rubber ring 32 glued and fixed to the inner surface of the protective cover plate 31, and the rubber ring 32 is embedded in the inner surface of the protective cover plate 31. When the protective cover 31 is inserted into the inner side of the bolt groove 7 and contacts the inner wall of the bolt groove 7, it can prevent the protective cover plate 31 from spinning in the subsequent concrete making process and improve the sealing effect. In the early stage, when the steel formwork 2 5 and the steel formwork 1 6 are combined and connected, the connecting strip 1 and the connecting strip 2 2 are first fitted together, and the positioning plug 41 is inserted into the positioning plug hole 42, and the triangular block 422 is squeezed into the rectangular bayonet 411 to achieve the preliminary positioning and alignment between the connecting strip 1 and the connecting strip 2. Then, the protective cover plate 31 is pulled sideways with force, so that the cylindrical side rod 36 slides with the inner base plate 35 and compresses the spring 34 until the rubber ring 32 moves out of the inner side of the bolt groove 7. At this time, the protective cover plate 31 can be rotated, so that the protective The cover plate 31 is rotated away from the opening of the bolt groove 7, so that the operator can insert the connecting bolt 81 into the inner side of the bolt groove 7 and then tighten it with the connecting nut 82 to achieve a stable connection between the connecting strip 1 and the connecting strip 2, thereby completing the stable connection between the steel template 2 5 and the steel template 1 6. After all the connecting bolts 81 and the connecting nuts 82 are connected and fixed, the protective cover plate 31 can be pulled sideways again and rotated back to the opening of the bolt groove 7, and then the protective cover plate 31 can be loosened. Under the push of the spring 34, the inner base plate 35 pulls the protective cover plate 31 back through the cylindrical side rod 36, and finally the protective cover plate 31 covers the opening of the bolt groove 7, and the rubber gasket 32 ​​enters the bolt groove 7. This can achieve the sealing of the bolt groove 7 after the steel formwork 2 5 and the steel formwork 1 6 are connected, thereby preventing unsolidified concrete from dripping into the bolt groove 7 during the subsequent concrete making process and causing contamination of the connecting bolts 81 and the connecting nuts 82. Later, when the concrete making is completed and the steel formwork 2 5 and the steel formwork 1 6 need to be separated, it is only necessary to pull the protective cover plate 31 sideways and rotate it away from the bolt groove 7 to remove the connecting bolts 81 and the connecting nuts 82 normally, and then force the connecting strip 1 and the connecting strip 2 2 apart, so that the triangular block 422 is squeezed and elastically deformed and squeezed out of the rectangular bayonet 411, and the positioning block 41 can be pulled out of the positioning hole 42, thereby achieving the smooth separation of the steel formwork 2 5 and the steel formwork 1 6 after concrete making.

[0031] One end of the spring 34 abuts against the side surface of the inner base plate 35 , and the other end of the spring 34 abuts against the inner wall of the inner sliding groove 33 .

[0032] Among them, the surfaces of connecting bar 1 and connecting bar 2 are both provided with multiple circular rod holes connected to the inner sliding groove 33, and the circular rod holes correspond to the cylindrical side rods 36, allowing the cylindrical side rods 36 to pass through smoothly and move subsequently.

[0033] A pinch block is welded and fixed on the outer surface of the protective cover plate 31 , and the pinch block is arc-shaped, which makes it convenient for the operator to pull the protective cover plate 31 sideways.

[0034] Although embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
