Description

Technical Field

[0001] The utility model belongs to the technical field of construction equipment, and particularly relates to a casting mold for an assembled precast column. Background Technique

[0002] An assembled precast column is a column that is precast after measuring the installation site. During installation, only the precast column needs to be transported to the construction site, inserted into the pile cap structure, and then the inner wall of the column and the pile cap are filled with steel fiber concrete. After the steel fiber concrete solidifies and reaches the strength, the installation of the column can be completed. The appearance of the assembled precast column avoids the situation such as site restrictions that occur during on-site casting of columns, and at the same time improves the construction efficiency.

[0003] Currently, in the casting of assembled precast columns, the common method is to use a formwork for enclosing. After pouring concrete in the formwork and waiting for it to solidify and form, the external formwork can be removed. Currently, most formworks are connected through the cooperation of some wooden boards and bolts, and the workload during splicing is large. At the same time, when building columns, a steel reinforcement cage needs to be placed inside the column, and during the concrete pouring process, the steel reinforcement cage needs to be positioned to prevent it from tilting. Currently, the common method for positioning the steel reinforcement cage is to use a rope for traction. By tying the rope to the steel reinforcement cage and connecting it to the top of the formwork, the inclination amplitude of the steel reinforcement cage during concrete pouring is relatively small. Then, after pouring, when the concrete is still viscous, the steel reinforcement cage is adjusted. This method is relatively cumbersome, and the resistance during the adjustment process is large, requiring a lot of time and effort.

[0004] Therefore, it is necessary to provide a new casting mold for assembled precast columns to solve the above technical problems. Content of the Utility Model

Detailed implementation manners

[0026] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0027] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0028] Example 1, please refer to Figure 1 - Figure 7, including a substrate 1 and four bottom plates 2 arranged on the top of the substrate 1. The tops of the four bottom plates 2 are all connected with splicing plates 3, and the tops of the four splicing plates 3 are all connected with top plates 4. As shown in Figure 1 shown, the four bottom plates 2 are connected end to end to form a rectangle. The positions of the four splicing plates 3 and the four top plates 4 respectively correspond to those of the four bottom plates 2. A positioning mechanism is arranged on the top of the four top plates 4. The positioning mechanism is used for limiting the steel reinforcement cage so that it will not shift during the concrete pouring process.

[0029] The specific designs of the above key components are described in detail below:

[0030] A first sponge strip 6 is placed on the top of the substrate 1. As shown in Figure 2 shown, the first sponge strip 6 is rectangular and corresponds to the bottoms of the four bottom plates 2. Two positioning bolts 5 are movably installed on the outer walls of the four bottom plates 2. The two positioning bolts 5 on any one bottom plate 2 are symmetrically arranged based on the midpoint of the bottom plate 2. In actual use, the four bottom plates 2 are fixed on the substrate 1 through eight positioning bolts 5, and by screwing the bolts, the bottom plates 2 are tightly pressed on the first sponge strip 6 to prevent leakage at the bottom during pouring.

[0031] Connecting bolts 7 are movably installed on the outer walls of the four splicing plates 3 and the four top plates 4. The connecting bolts 7 are located at the middle positions of the bottom edges of the splicing plates 3 and the top plates 4. Specifically, as shown in Figure 1 shown, mounting plates 701 are fixedly installed on the outer walls of the four bottom plates 2 and the four splicing plates 3. The mounting plates 701 are located at the middle positions of the top edges of the bottom plates 2 and the splicing plates 3. The positions of the mounting plates 701 correspond to those of the connecting bolts 7.

[0032] Connecting columns 8 are arranged between two adjacent bottom plates 2, two adjacent splicing plates 3, and two adjacent top plates 4. Grooves two 12 are opened on the shorter outer walls on both sides of the bottom plates 2, the splicing plates 3, and the top plates 4. Two embedding blocks 802 are fixedly installed on the connecting columns 8. The embedding blocks 802 extend into the grooves two 12. Grooves one 10 are opened on one outer wall of the bottom plates 2, the splicing plates 3, and the top plates 4. Tightening blocks 801 are fixedly installed on the outer walls on both sides of the connecting columns 8. The tightening blocks 801 extend into the grooves one 10. A sealing strip 9 is fixedly installed on the connecting columns 8. As shown in Figure 3 and Figure 7 shown, inclined surfaces are provided on the shorter outer walls on both sides of the bottom plates 2, the splicing plates 3, and the top plates 4. After the two tightening blocks 801 on the connecting columns 8 are clamped into the grooves one 10, the adjacent inclined surfaces are fully attached together, and the sealing strip 9 abuts against the connection position of the inclined surfaces to seal it.

[0033] Insertion interfaces 11 are provided at the tops of the four bottom plates 2 and the four splicing plates 3. Embedded plates 1101 are fixedly installed at the bottoms of the four splicing plates 3 and the four top plates 4. The embedded plates 1101 are adapted to the insertion interfaces 11. During actual use, multiple splicing layers formed by the four splicing plates 3 can be prepared. By splicing multiple layers of splicing plates 3 between the four bottom plates 2 and the four top plates 4, the pouring of columns with different heights can be handled. Sponge strips II 13 are provided at the tops of the four bottom plates 2 and the four splicing plates 3. As shown in Figure 3 shown, the sponge strips II 13 are arranged around the insertion interfaces 11.

[0034] The positioning mechanism includes two mounting seats 14. The mounting seats 14 are U-shaped and are fixedly installed on the tops of the two symmetrically arranged top plates 4. A rotating cylinder 15 is rotatably installed in any one of the mounting seats 14. A threaded rod 16 is slidably installed in the rotating cylinder 15. One end of the rotating cylinder 15 is open. One end of the threaded rod 16 extends outside the rotating cylinder 15 through the opening. A stabilizing plate 17 is fixedly installed at one end of the threaded rod 16. A pressing plate 18 is fixedly installed on the stabilizing plate 17.

[0035] Extension plates 19 are slidably installed on both sides of any one of the stabilizing plates 17. The extension plates 19 are L-shaped. The two extension plates 19 are mirror-symmetrically arranged based on the midpoint of the stabilizing plate 17. Lugs 20 are fixedly installed on the outer walls of one sides of the four extension plates 19. Bolts 21 are movably installed on the corresponding two lugs 20. As shown in Figure 5 shown, limiting rods are fixedly installed on the outer walls of one sides of the four extension plates 19. Side blocks are fixedly installed on the outer walls of one sides of the two stabilizing plates 17. The four limiting rods respectively penetrate through the four side blocks and are slidably connected to them. Return springs are sleeved on the four limiting rods.

[0036] Outer sleeves 1501 are rotatably sleeved on the outer walls of the two rotating cylinders 15. The outer sleeves 1501 are located at the edge of the open end of the rotating cylinder 15. As shown in Figure 6 shown, the outer sleeves 1501 are rotatably installed on the outer walls of the rotating cylinders 15 by means of bearings. A threaded cylinder 1502 is fixedly installed on the outer sleeves 1501. One end of the threaded rod 16 penetrates through the threaded cylinder 1502 and is threadedly connected to its inner wall. During actual use, it is necessary to limit the threaded rod 16 so that it can only move horizontally and cannot rotate.

[0037] The working principle of the prefabricated column pouring mold provided by the present utility model is as follows:

[0038] When the casting of the assembled precast column is required, first, the staff can splice the four bottom plates 2 end to end through the four connecting columns 8. When splicing, the two embedding blocks 802 on the connecting column 8 are respectively embedded into the two grooves II 12 close to each other on the adjacent two bottom plates 2, and the two abutting blocks 801 on the connecting column 8 are respectively embedded into the two grooves I 10 close to each other on the adjacent two bottom plates 2. Specifically, as shown in Figure 7 shown, after the installation of the connecting column 8 is completed, the sealing strip 9 abuts against the gap where the inclined surfaces of the adjacent two bottom plates 2 contact each other.

[0039] Subsequently, the four bottom plates 2 are fixedly installed on the base plate 1 through the positioning bolts 5, and the four bottom plates 2 are fully pressed against the first sponge strip 6 by screwing the positioning bolts 5 to avoid leakage at the bottom.

[0040] Subsequently, the four splicing plates 3 are spliced end to end in the way of splicing the four bottom plates 2 through the four connecting columns 8. After the splicing is completed, the inner embedded plates 1101 at the bottoms of the four splicing plates 3 are aligned with the insertion interfaces 11 at the tops of the four bottom plates 2 and placed in. At this time, the connecting bolts 7 are aligned with the mounting plates 701. By screwing the connecting bolts 7, the four splicing plates 3 are attached to the tops of the four bottom plates 2 and fully press the second sponge strip 13 at the tops of the bottom plates 2. When dealing with the casting of a relatively high column, multiple splicing plates 3 can be spliced in multiple layers at the joints with the connecting columns 8 and connected to the splicing plates 3 on the lower layer in the above way.

[0041] After splicing to a sufficient height through multiple splicing plates 3, the staff can splice the four top plates 4 end to end through the connecting columns 8. After completion, the inner embedded plates 1101 at the bottoms of the four top plates 4 are inserted into the insertion interfaces 11 on the four splicing plates 3 on the next layer and fixed by screwing the connecting bolts 7.

[0042] Subsequently, the steel reinforcement cage is placed through the tops of the four top plates 4, and the bottom end of the steel reinforcement cage contacts the base plate 1. At this time, the two rotating cylinders 15 can be respectively rotated, and the two outer sleeves 1501 are rotated. The rotation of the outer sleeve 1501 drives the threaded cylinder 1502 to rotate, so that the threaded rod 16 moves out of the rotating cylinder 15, and finally the two stabilizing plates 17 approach the steel reinforcement cage. Through the two extension plates 19, the two extension plates 19 abut against the two side edges of the steel reinforcement cage, while the stabilizing plates 17 abut against the outer wall of one side of the steel reinforcement cage. The two extension plates 19 will approach each other under the reset effect of the reset spring, thus preventing the steel reinforcement cage from shifting left and right, and the two stabilizing plates 17 on both sides can effectively prevent it from shifting back and forth after abutting against the steel reinforcement cage. And by inserting the two pins 21 into the lugs 20, it forms as shown in Figure 5In the shown state, it can effectively prevent the two rotating cylinders 15 from rotating by themselves. At the same time, the two pressing plates 18 need to be located at the top of the steel bars spanning across the steel reinforcement cage to prevent the steel reinforcement cage from being jacked up during concrete pouring.

[0043] Compared with the related technologies, the precast column casting mold provided by the present utility model has the following effects:

[0044] The present utility model provides a precast column casting mold. In this application, the bottom plate 2, splicing plates 3 and top plate 4 that can be freely spliced can be freely adjusted according to the height of the column. At the same time, through the first sponge strip 6, the second sponge strip 13 and the sealing strip 9, it can effectively prevent the leakage of viscous concrete. Further, after being adjusted by the two positioning mechanisms, it can effectively limit the steel reinforcement cage, thereby preventing excessive deviation during concrete pouring, and thus improving the pouring accuracy and efficiency to a certain extent.
