Abstract

The utility model relates to the technical field of constructional engineering, and discloses a cast-in-place concrete column wood block formwork structure which comprises a round formwork, hoops are fixedly installed on the side wall of the outer side of the round formwork at intervals, lock catch blocks are installed on the hoops, and each lock catch block comprises a main lock catch block and an auxiliary lock catch block. When a nut is screwed to enable the main buckling block and the auxiliary buckling block to be preliminarily connected through threads, a clamping plate on the auxiliary buckling block can drive an adjusting rod to move through an adjusting groove in an adjusting disc, and the adjusting rod moves in a matched mode and is buckled in a clamping groove of a connecting rod, so that in the concrete operation process, the connecting rod is clamped in the clamping groove. When the threaded connection part is loosened due to the influence of concrete side pressure and vibration force, the clamping plate is still buckled in the clamping groove, so that the connection relation between the main buckling block and the auxiliary buckling block still keeps certain strength, and the phenomenon that the threaded connection part is loosened during operation can be effectively avoided. Related defects occur in concrete pouring due to loosening of threaded connection caused by concrete operation.

Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and more specifically to a cast-in-place concrete column wooden block formwork structure. Background Technology

[0002] In the field of building construction, the forming of cast-in-place concrete columns often relies on outer circular lightweight wooden block formwork. Currently, the connection method of such formwork is usually to set a suitable clamp on the outside of the formwork, and then use the bolts and nuts on the clamp to make threaded connections to fix the two formwork blocks, thereby forming the circular mold required for pouring concrete columns.

[0003] However, during the concrete pouring process, the huge lateral pressure generated by the concrete and the strong vibration force during compaction will directly act on the formwork and clamp connection structure. Since it relies solely on the threaded connection on the clamp, the threaded connection is very prone to loosening under the long-term impact of these external forces.

[0004] Loose threads pose a significant threat to the construction quality of cast-in-place concrete columns. The connection stability between formwork blocks deteriorates, and gaps easily appear between the two outer lightweight wooden blocks, leading to grout leakage during concrete pouring. This results in defects such as honeycomb and pitting on the surface of the concrete column, severely affecting its appearance quality and structural strength. Furthermore, such loose connections can cause loss of dimensional accuracy in the concrete column, potentially leading to issues such as the column's roundness not meeting design requirements or uneven diameter, thus compromising the stability and safety of the building structure. Therefore, we propose a wooden block formwork structure for cast-in-place concrete columns. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cast-in-place concrete column wooden block formwork structure to solve the problem of using a lightweight wooden block formwork structure for cast-in-place concrete columns.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a cast-in-place concrete column wooden block formwork structure, including a circular formwork, the circular formwork being an arc-shaped plate, two sets of circular formwork, the two sets of circular formwork being symmetrically arranged, clamps being fixedly installed at intervals on the outer sidewalls of the circular formwork, and locking blocks being installed on the clamps, the locking blocks including main locking blocks and auxiliary locking blocks, the main locking blocks and auxiliary locking blocks being fixedly installed at both ends of the clamps respectively, and the main locking blocks on one set of clamps on the two sets of circular formwork correspond to the auxiliary locking blocks on the other set of clamps, a connecting rod being fixedly installed on the main locking block, and an insertion hole being opened on the auxiliary locking block corresponding to the position of the connecting rod on the main locking block, a locking cap being provided on the end of the auxiliary locking block away from the main locking block on the other set of clamps on the same side, an adjustment component being provided inside the auxiliary locking block, slots being opened on the front and rear sides of the connecting rod, and auxiliary slots being opened on both sides of the auxiliary locking block corresponding to the positions of the slots, a locking plate being provided inside the auxiliary slot, and the locking plate and the adjustment component being connected to each other.

[0007] Preferably, the locking cap includes a nut, an adjusting plate, and an adjusting groove. The inner sidewall of the nut is provided with threads, and the connecting rod at the end away from the main locking block is provided with threads that match the threads on the inner sidewall of the nut. The adjusting plate is fixedly installed on the side of the nut near the auxiliary locking block. The adjusting groove is an arc-shaped groove, which is opened at both ends of the sidewall of the adjusting plate. One end of the adjusting groove is located on the sidewall of the adjusting plate away from the nut, and the other end of the adjusting groove is located on the sidewall of the adjusting plate near the nut.

[0008] Preferably, the adjustment assembly includes an adjustment rod, a movable groove, a moving block, a moving groove, and an auxiliary spring. The movable groove is located on both sides of the corresponding insertion hole on the side wall of the auxiliary buckle block. The moving groove is located on both sides of the corresponding insertion hole inside the auxiliary buckle block. The moving groove, the movable groove, and the auxiliary groove are interconnected. The moving block is disposed inside the moving groove.

[0009] Preferably, one end of the movable block is fixedly installed on one side wall of the card plate, the adjusting rod is fixedly installed on the other end of the movable block, and the auxiliary spring is disposed in the movable groove, with both ends of the auxiliary spring connected to one side wall of the movable block and the inner side wall of the movable groove, respectively.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In this invention, after the nut is tightened to initially connect the main and auxiliary fastener blocks via threads, the retaining plate on the auxiliary fastener block will move the adjusting rod through the adjusting groove on the adjusting plate, adapting to the movement and locking into the groove of the connecting rod. This ensures that even if the threaded connection becomes loose due to the lateral pressure and vibration force of the concrete during concrete operation, the retaining plate will still lock into the groove, maintaining a certain strength in the connection between the main and auxiliary fastener blocks. This effectively prevents defects in concrete pouring caused by loosening of the threaded connection during concrete operation. Attached Figure Description

[0018] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0019] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0020] like Figures 1-4 As shown, the cast-in-place concrete column wooden block formwork structure includes a circular formwork 1, which is an arc-shaped plate. There are two sets of circular formwork 1, and the two sets of circular formwork 1 are symmetrically arranged.

[0021] Furthermore, clamps 2 are fixedly installed at intervals on the outer sidewall of the circular template 1. Locking blocks 3 are installed on the clamps 2. The locking blocks 3 include main locking blocks and auxiliary locking blocks. The main locking blocks and auxiliary locking blocks are fixedly installed at both ends of the clamps 2, and the main locking blocks on one set of clamps 2 on the two sets of circular templates 1 correspond to the auxiliary locking blocks on the other set of clamps 2.

[0022] Furthermore, a connecting rod 4 is fixedly installed on the main buckle block.

[0023] Furthermore, the auxiliary fastener block has an insertion hole 9 at the position of the connecting rod 4 on the main fastener block.

[0024] Furthermore, a locking cap is provided at one end of the main buckle on another set of clamps 2 on the same side away from the auxiliary buckle block. An adjustment component is provided inside the auxiliary buckle block. The connecting rod 4 has slots 10 on both the front and rear sides. Auxiliary slots 15 are provided on both sides of the corresponding insertion hole 9 inside the auxiliary buckle block. The positions of the auxiliary slots 15 and the slots 10 correspond to each other. A card plate 16 is provided inside the auxiliary slot 15. The card plate 16 and the adjustment component are connected to each other.

[0025] In this embodiment, by turning the lock cap, the lock cap adjusts the adjustment component, which in turn moves the locking plate 16 within the auxiliary groove 15, causing the locking plate 16 to move into the groove 10 on the connecting rod 4, thus completing the locking and reinforcement operation.

[0026] Furthermore, the locking cap includes a nut 5, an adjusting plate 6, and an adjusting groove 7. The inner sidewall of the nut 5 is provided with threads, and the connecting rod 4 is provided with threads on the end away from the main fastener block that are compatible with the threads on the inner sidewall of the nut 5. The adjusting plate 6 is fixedly installed on the side of the nut 5 near the auxiliary fastener block. The adjusting groove 7 is an arc-shaped groove, which is opened at both ends of the sidewall of the adjusting plate 6. One end of the adjusting groove 7 is located on the sidewall of the adjusting plate 6 away from the nut 5, and the other end of the adjusting groove 7 is located on the sidewall of the adjusting plate 6 near the nut 5.

[0027] In this embodiment, the nut 5 is screwed onto the connecting rod 4. When the adjusting plate 6 gradually comes into contact with the auxiliary fastener block, the adjusting groove 7 on the adjusting plate 6 will come into contact with the adjusting component. Through the rotation of the nut 5 and the arc-shaped setting of the adjusting groove 7, the adjusting plate 6 drives the adjusting groove 7 to adjust the adjusting component, thereby completing the locking and reinforcement operation.

[0028] Furthermore, the adjustment assembly includes an adjustment rod 8, a movable groove 11, a moving block 12, a moving groove 13, and an auxiliary spring 14. The movable groove 11 is located on both sides of the corresponding insertion hole 9 on the side wall of the auxiliary fastener block. The moving groove 13 is located on both sides of the corresponding insertion hole 9 inside the auxiliary fastener block. The moving groove 13, the movable groove 11, and the auxiliary groove 15 are interconnected. The moving block 12 is located inside the moving groove 13. The moving block 12 is rectangular. One end of the moving block 12 is fixedly installed on one side wall of the clamping plate 16. The adjustment rod 8 is fixedly installed on the other end of the moving block 12. The adjustment rod 8 can be extended and retracted. The auxiliary spring 14 is located inside the moving groove 13. The two ends of the auxiliary spring 14 are respectively connected to one side wall of the moving block 12 and the inner side wall of the moving groove 13.

[0029] In this embodiment, the locking cap rotates on the connecting rod 4, causing the side wall of the adjusting plate 6 on the locking cap to press against the adjusting rod 8, causing the adjusting rod 8 to retract. When the adjusting plate 6 rotates to the position where the adjusting groove 7 on the adjusting plate 6 corresponds to the position of the adjusting rod 8, the adjusting rod 8 will spring back and move into the adjusting groove 7. As the adjusting plate 6 rotates, it moves on the movable groove 11 with the adjustment of the adjusting groove 7, thereby driving the locking plate 16 connected by the moving block 12 to adapt and move in the auxiliary groove 15, so that the locking plate 16 moves into the locking groove 10, thereby completing the locking and reinforcement of the connecting rod 4.

[0030] Working principle and usage process of this utility model:

[0031] In use, when the two sets of circular templates 1 are assembled, the connecting rod 4 on the main buckle block is inserted into the insertion hole 9 on the auxiliary buckle block. At this time, the lock cap is screwed on the connecting rod 4. When the nut 5 on the lock cap is rotated to the designated position, the adjusting plate 6 will contact the adjusting rod 8 and press the adjusting rod 8. When the adjusting plate 6 rotates with the lock cap so that the adjusting groove 7 on the adjusting plate 6 corresponds to the adjusting rod 8, the adjusting rod 8 will spring back and snap into the inside of the adjusting groove 7. With the rotation of the adjusting plate 6, under the adaptation and adjustment of the adjusting groove 7, the adjusting rod 8 moves in the movable groove 11 and drives the card plate 16 connected by the moving block 12 to move in the auxiliary groove 15 until it snaps into the inside of the card groove 10 on the connecting rod 4, thereby completing the locking and reinforcement operation.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
