Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated columns, in particular to a prefabricated column connection structure which is easy to position. Background Art

[0002] Prefabricated columns are columns made of reinforced concrete. They are the most basic load-bearing components in various engineering structures such as houses, bridges and hydraulic structures. They are often used as floor pillars, bridge piers and foundation columns, making buildings more stable and strong. They have the characteristics of high strength, high precision, stable quality and fast construction. Prefabricated columns can be divided into various types such as prestressed concrete columns, reinforced concrete columns and hollow slab columns according to their manufacturing methods. At present, prefabricated columns require upper and lower columns to be spliced ​​and grouted. They are currently suitable for prefabricated column connection structures on the market, but there are still some disadvantages.

[0003] The existing prefabricated column connection structure has the problem that the lower prefabricated column is placed below the upper prefabricated column, which is unstable and prone to tipping over during grouting. At the same time, the fixation between the upper and lower prefabricated columns is completed by manual fixation. Since the prefabricated columns are generally large, manual fixation alone is a waste of manpower. For example, a Chinese utility model patent with authorization announcement number CN219343485U discloses a prefabricated column connection structure that is easy to position, including an upper prefabricated column, a lower prefabricated column arranged below the upper prefabricated column, and a fixing protrusion embedded in the middle of the lower prefabricated column and the upper prefabricated column for positioning, a fixed connecting plate, the fixed connecting plate is arranged between the upper prefabricated column and the lower prefabricated column, a fixing mechanism, the fixing mechanism is arranged at an equal angle on the outside of the fixed connecting plate, and an elongated steel bar, the elongated steel bar is fixedly connected to the inside of the fixing hole, and the elongated steel bar is arranged at an equal angle in the middle of the fixed connecting plate. The prefabricated column connection structure that is easy to position is convenient for quickly positioning and connecting the prefabricated columns to be assembled and installed, and is convenient for fixing and limiting the upper prefabricated column, the lower prefabricated column and the fixed connection plate. Moreover, through the setting of the fixing holes, the elongated steel bars and the casting long grooves, it is convenient to enhance the integrity of the connection when fixing it with concrete pouring, and the fastening is good. However, this device has the problem that the lower prefabricated column is unstable because it is placed below the upper prefabricated column, and it is easy for the lower prefabricated column to topple over during grouting. At the same time, the fixation between the upper and lower prefabricated columns is completed by manual fixation. Since the prefabricated columns are generally large, it is relatively wasteful to fix them by manpower alone. Therefore, we propose a prefabricated column connection structure that is easy to position to solve the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide a precast column connection structure that is convenient for positioning, so as to solve the problems in the above-mentioned background technology. For the current precast column connection structure, since the lower precast column is placed below the upper precast column, there is instability, and when grouting, the lower precast column is prone to tipping. At the same time, the fixation between the upper and lower precast columns is completed manually. Due to the generally large size of precast columns, relying solely on manpower for fixation is relatively labor-consuming.

The anti-tipping mechanism includes a fixing plate, a sliding block, an electromagnetic slide rail and a controller. The fixing plates are closely attached to the front and rear of the lower part of the lower precast column, and a sliding block is fixedly connected to the lower part of the fixing plate. The sliding block is slidably installed above the electromagnetic slide rail, and a controller is arranged on the front left side of the electromagnetic slide rail;

[0009] Convenient positioning mechanisms are symmetrically arranged on the left and right sides of the outer sides of the lower precast column and the upper precast column. The convenient positioning mechanism includes a sealing block, a positioning clamping plate, a gear block, a clamping block, a clamping groove, a connecting rod, a fixing frame, a fixing block, a rotating rod and a fixing frame. An upper precast column is installed above the lower precast column, and a sealing block is arranged outside the connection between the lower precast column and the upper precast column, and the sealing block is installed in the middle of the inner side of the gear block.

[0014] Preferably, a fixing block is fixedly installed at the rear of the outer side of the connecting rod, a rotating rod is installed inside the fixing block, the lower part of the rotating rod is rotatably connected to the fixing frame, and a motor is connected to the rear side of the lower part of the rotating rod.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this precast column connection structure facilitating positioning, by providing a positioning mechanism, the upper and lower precast columns can be automatically positioned and fixed, enabling the upper and lower precast columns to be stably grouted and connected together, greatly saving the output of human labor. At the same time, an anti-tipping mechanism is provided, strengthening a support structure on the outer side of the lower precast column, firmly fixing the lower precast column and preventing it from tipping over. Additionally, a positioning anti-slip and sealing mechanism is provided, preventing sliding during the positioning of the upper and lower precast columns and preventing overflow during grouting.

[0016] 1. There are a fixing plate, a sliding block, an electromagnetic slide rail and a controller. The bottom plate is directly placed on the ground, and a placement groove is opened in the middle of the bottom plate. The lower precast column is placed inside the placement groove. Fixing plates are symmetrically arranged on the front and rear sides below the lower precast column. The lower part of the fixing plate is fixedly connected to the sliding block, and the sliding block is slidably installed above the electromagnetic slide rail. When the controller is turned on, the controller can control the sliding block to slide above the electromagnetic slide rail. When the sliding block slides inward, it can drive the fixing plate to move inward together, so that the fixing plate is closely attached to the outer side of the lower precast column, strengthening a support structure on the outer side of the lower precast column, firmly fixing the lower precast column and preventing it from tipping over.

[0017] 2. There are positioning clamping plates, gear blocks, clamping blocks and clamping grooves. Since the lower precast column and the upper precast column need to be spliced and grouted together, that is, after the lower precast column and the upper precast column are connected together, the motor is turned on. The motor can cause the rotating rod to rotate. Since a fixing block is installed on the outer side of the rotating rod and a connecting rod is connected to the front of the fixing block, when the rotating rod rotates, through the connection of the fixing block, it will push the connecting rod to slide inward inside the fixing frame. The inner side of the connecting rod is connected to the positioning clamping plate, that is, the connecting rod will push the positioning clamping plate to move inward, thereby firmly positioning and fixing the lower precast column and the upper precast column, and the lower precast column and the upper precast column can be automatically positioned and fixed, enabling the lower precast column and the upper precast column to be stably grouted and connected together, greatly saving the output of human labor.

[0018] 3. A sealing block and a gear block are provided. By equiangularly arranging the gear block inside the positioning clamping plate, when the positioning clamping plate clamps and positions the lower precast column and the upper precast column, the gear block will closely fit with the outer sides of the lower precast column and the upper precast column. The setting of the gear block can increase the friction force between the positioning clamping plate and the lower precast column and the upper precast column. In addition, a sealing block is installed in the middle of the inner side of the gear block, and the sealing block is closely attached to the outer side of the connection between the lower precast column and the upper precast column, which can prevent the grout from overflowing when grouting into the casting grooves inside the lower precast column and the upper precast column.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-5, the present utility model provides a technical solution: a precast column connection structure convenient for positioning, including: a bottom plate 1, a placement groove 2, a lower precast column 3, a fixing plate 4, a sliding block 5, an electromagnetic slide rail 6, a controller 7, a casting groove 8, an upper precast column 9, a sealing block 10, a positioning clamping plate 11, a gear block 12, a clamping block 13, a clamping groove 14, a connecting rod 15, a fixing frame 16, a fixing block 17, a rotating rod 18 and a motor 19;

[0027] As Figure 1 , Figure 3 and Figure 5 shown in, the bottom plate 1 is closely attached to the ground. A placement groove 2 is opened in the middle of the bottom plate 1. The lower precast column 3 is placed in the placement groove 2. Fixing plates 4 are symmetrically arranged on the front and rear sides below the lower precast column 3. A sliding block 5 is fixedly connected below the fixing plate 4. The sliding block 5 is slidably installed above the electromagnetic slide rail 6. The controller 7 is turned on. The controller 7 can control the sliding block 5 to slide above the electromagnetic slide rail 6. When the sliding block 5 slides inward, it can drive the fixing plate 4 to move inward together, so that the fixing plate 4 is closely attached to the outer side of the lower precast column 3, that is, a support structure is reinforced on the outer side of the lower precast column 3, making the lower precast column 3 firmly fixed and preventing it from toppling;

[0028] As Figure 1 , Figure 2 and Figure 4 shown in, after the lower precast column 3 is placed stably, the upper precast column 9 can be placed above the lower precast column 3, and then the motor 19 is turned on. The motor 19 can make the rotating rod 18 rotate. Since a fixing block 17 is installed on the outer side of the rotating rod 18 and a connecting rod 15 is connected in front of the fixing block 17, that is, when the rotating rod 18 rotates, through the connection of the fixing block 17, the rotation of the rotating rod 18 will push the connecting rod 15 to slide inward in the fixing frame 16. At the same time, a positioning clamping plate 11 is connected to the inner side of the connecting rod 15, that is, the connecting rod 15 will push the positioning clamping plate 11 to move inward. A clamping groove 14 is opened on the inner side of the positioning clamping plate 11 connected to the right side of the connecting rod 15, and a clamping block 13 is installed on the right side of the positioning clamping plate 11 connected to the left side of the connecting rod 15. The setting of the clamping block 13 and the clamping groove 14 can firmly clamp the outer sides of the lower precast column 3 and the upper precast column 9, so as to firmly position and fix the lower precast column 3 and the upper precast column 9, and can automatically position and fix the lower precast column 3 and the upper precast column 9, so that the lower precast column 3 and the upper precast column 9 can be stably grouted and connected together, greatly saving the output of human labor;

[0029] By equally angularly arranging gear blocks 12 inside the positioning clamping plate 11, when the positioning clamping plate 11 clamps and positions the lower precast column 3 and the upper precast column 9, the gear blocks 12 will closely fit against the outer sides of the lower precast column 3 and the upper precast column 9. The arrangement of the gear blocks 12 can increase the friction force between the positioning clamping plate 11 and the lower precast column 3 and the upper precast column 9, preventing the situation of clamping slippage. Additionally, a sealing block 10 is installed in the middle of the inner side of the gear block 12, and the sealing block 10 is closely arranged against the outer side of the connection between the lower precast column 3 and the upper precast column 9, which can prevent overflow when grouting into the casting grooves 8 inside the lower precast column 3 and the upper precast column 9.
