Description

Technical Field

[0001] The utility model relates to the field of assembled construction, in particular to a replaceable lower end mold of a prefabricated column. Background Art

[0002] With the vigorous development of prefabricated buildings, frame-type PC structures are becoming more and more numerous, which increases the difficulty of merging beam and column molds. Since there are many types of columns merged in the steel mold, the fixed dimensions of the lower end mold sleeve of the column overlap a lot, which will cause the sliding tooth size to deviate. The existing beam-column mold merging device has the following problems:

[0003] 1. Overlapping sleeve dimensions: Due to the difficulty in merging molds such as columns, the fixed dimensions of the sleeves at the lower end of the column overlap a lot, which can easily cause the sliding thread dimension to deviate.

[0004] 2. High mold cost: The traditional lower mold adopts an integral design, which is difficult to process and has high cost.

[0005] 3. Low sleeve fixing accuracy: The traditional lower end mold adopts a single fixing method, which cannot meet the fixing requirements of sleeves of different sizes, and the accuracy is difficult to guarantee. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a replaceable lower end mold for a prefabricated column, so as to reduce the overlap of sleeve sizes, improve the accuracy of sleeve fixing, and reduce mold costs while keeping the main pattern of the lower end mold unchanged.

[0007] In order to achieve the above purpose, a replaceable lower end mold of a prefabricated column is designed, comprising

[0008] The lower mold frame has four fixing holes at the four corners, and four through slots are arranged on the circumference of the lower mold frame. Each through slot and two fixing holes adjacent to the through slot are in the same straight line.

[0009] A plurality of iron plates are provided with middle hollow structures of different sizes. The four corners of each iron plate are provided with fixing holes matched with the lower end mold frame. The peripheral side of each iron plate is provided with a sleeve size fixing hole, and the sleeve size fixing hole matches with the through groove of the lower end mold frame.

[0010] The iron plate is detachably connected to the lower end mold body through a fixing hole, a sleeve size fixing hole and a through groove.

[0011] A sleeve size fixing hole with precise aperture is opened on the iron plate to ensure the accuracy of sleeve positioning.

[0012] A column shear groove is provided in the middle of the lower end mold frame.

[0013] The upper and lower sides of the lower mold frame are provided with upper and lower rib plates, and the front and rear sides of the lower mold frame are provided with vertical rib plates.

[0014] A mold fixing hole and a positioning pin hole are provided on the left side or the right side of the lower end mold frame.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] 1. Save mold costs: By opening several more iron plates with fixed sleeve sizes, a lot of mold costs can be saved compared to the old lower end mold and the accuracy of prefabricated column sleeve casting can be improved.

[0017] 2. Improve operating efficiency: By optimizing the design of the lower die, the weight of the die is reduced, making the operation more convenient and quick.

[0018] 3. Precise control of accuracy: The upper opening of the lower die and the lower opening of the upper die of the lower die are designed with a coaxially adjustable taper structure to adjust the accuracy of the mold and thus better control the molding quality of the component.

[0019] 4. Reduce installation errors: By optimizing mold design, the time and cost of workers looking for molds are reduced, and the installation error rate is reduced.

[0020] 5. Convenient storage and transportation: By optimizing the mold design, the weight and volume of the mold are reduced, making storage and transportation more convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the purpose, principle and structure of the utility model clearer, it is further described below in conjunction with the drawings and specific embodiments.

[0026] The utility model provides a replaceable lower end mold for a prefabricated column, comprising:

[0027] The lower mold frame 2 has four fixing holes 1 at the four corners, four through slots 10 are arranged on the circumference of the lower mold frame 2, each through slot 10 and two fixing holes 1 adjacent to the through slot 10 are in the same straight line, and a column shear groove 3 is arranged in the middle of the lower mold frame. The upper and lower ribs 4 are arranged on the upper and lower sides of the lower mold frame 2, and the vertical ribs 5 are arranged on the front and rear sides of the lower mold frame 2. A mold fixing hole 6 and a positioning pin hole 7 are arranged on the left or right side of the lower mold frame 2.

[0028] Several iron plates 8, several iron plates 8 have hollow structures in the middle of different sizes, each iron plate 8 is provided with fixing holes 1 at the four corners that match the lower end mold frame 2, and each iron plate is provided with a sleeve size fixing hole 9 on the circumference, and the sleeve size fixing hole 9 matches the through slot 10 of the lower end mold frame. The iron plate is detachably connected to the lower end mold body through the fixing hole 1, the sleeve size fixing hole 9 and the through slot 10. The sleeve size fixing hole 9 with a precise aperture is opened on the iron plate to ensure the accuracy of sleeve positioning.

[0029] The device of the present application is used for the production of assembled prefabricated columns, and the specific implementation steps are as follows:

[0030] The S1 bolts pass through the fixing holes 1 at the four corners of the iron plate 8 and the fixing holes 1 at the four corners of the lower end mold frame 2, and the bolts are tightened to achieve a fixed matching connection between the iron plate 8 and the lower end mold frame 2.

[0031] S2 assembles the integral lower end mold formed by the iron plate 8 and the lower end mold frame 2 into the prefabricated column casting template.

[0032] S3 inserts a pre-buried sleeve fastener (such as rubber) into the sleeve size fixing hole 9 of the iron plate 8 to form a hollow sleeve during the casting of the prefabricated column.

[0033] S4 pours the prefabricated column formwork.

[0034] S5 After the casting of the prefabricated column is completed, the pre-buried sleeve fasteners in the sleeve size fixing holes 9 are taken out, and the overall lower end mold is removed.

[0035] When it is necessary to build prefabricated column casting templates of different specifications, it is only necessary to make iron plates 8 with different specifications of sleeve size fixing holes 9, dismantle the original iron plates 8 by bolts, and assemble and connect the new iron plates 8 with the lower end mold frame 2 with bolts to form the lower end mold of the prefabricated column casting template that meets the new specifications.

[0036] It is worth mentioning that:

[0037] In the case of the lower end mold frame 2 unchanged, several more iron plates 8 with fixed sleeve sizes are opened. In this way, the corresponding iron plates 8 can be selected for fixing according to different prefabricated column sleeve size requirements while keeping the lower end mold frame 2 unchanged, avoiding the overlapping phenomenon of sleeve sizes.

[0038] The detachable design is adopted. By detachably connecting the iron plate 8 with the lower mold frame 2, replacement and maintenance can be conveniently performed, thereby reducing the manufacturing cost of the mold.

[0039] The design of the iron plate 8 takes into account the precision requirements of the casting size of the prefabricated column sleeve. The iron plate 8 is provided with a precise prefabricated column sleeve aperture to ensure the accuracy of the sleeve fixation. At the same time, by adding multiple iron plates 8, it can adapt to the fixing requirements of sleeves of different sizes.

[0040] The material of the iron plate 8 is selected from high-strength steel. By selecting high-strength steel, the strength and durability of the iron plate can be guaranteed, and the service life of the mold can be extended. At the same time, high-strength steel can also improve the stability of the casting of the prefabricated column sleeve, and further ensure the accuracy of the casting size of the prefabricated column sleeve.

[0041] The surface treatment of the iron plate 8 adopts chrome plating process. Chrome plating can increase the corrosion resistance and aesthetics of the iron plate 8, and at the same time can also improve the hardness of the iron plate, further ensuring the accuracy and stability of the casting of the prefabricated column sleeve.

[0042] The design of the iron plate 8 takes into account the processing requirements. The shapes of the sleeve aperture and profile opened on the iron plate 8 take into account the limitations of the processing equipment and the processing accuracy requirements, which can ensure the processing quality and accuracy of the iron plate 8. At the same time, considering the processing requirements, the shape and structure of the iron plate 8 can also be optimized to reduce the manufacturing cost of the mold.

[0043] The device for controlling the casting size deviation of the prefabricated column sleeve of the utility model can achieve the goals of saving mold costs, improving production efficiency, and ensuring product quality. The device of the utility model has higher flexibility and adaptability, and can meet the production requirements of columns of different types and specifications. At the same time, the embodiments of the utility model can also be selected and adjusted according to actual needs.

[0044] In general, the utility model provides a brand-new device for controlling sleeve size deviation, which has broad application prospects and market potential.

[0045] The above is only a specific implementation method of this utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical solution and new concept of the utility model, shall be covered by the protection scope of the utility model.
