Description
Technical Field
[0001] The utility model belongs to the technical field of concrete wall construction, and particularly relates to a joint reinforcement device for a plain concrete wall. Background Art
[0002] Concrete jointing in building walls involves leaving a joint in the upper portion of an existing concrete wall, then pouring concrete over it, so that the new wall is cemented onto the old. Conventional methods for concrete jointing are prone to problems such as leaks and misaligned joints. These problems are often caused by the impact load and weight of the formwork system on the bottom during the pouring process, which gradually increases, leading to leaks in the formwork gaps.
[0003] The existing ordinary formwork reinforcement system can only be evenly distributed on the side of the concrete formwork to balance the force. It is difficult to ensure that the concrete formwork is sufficiently stable at the bottom joint position. In addition, the construction is manual and the operation is quite arbitrary. Therefore, a device that can reinforce the bottom joint position is needed to avoid problems such as leakage during concrete pouring. Utility Model Content
[0004] The technical problem to be solved by the present invention is to provide a joint reinforcement device for a plain concrete wall in response to the deficiencies in the above-mentioned prior art. The device has a simple structure and a reasonable design. By arranging a first steel plate, it is convenient to provide a supporting force for the second steel plate, thereby forming a joint reinforcement mechanism and applying pressure to the bottom of the concrete formwork, thereby enhancing the tightness of the bottom of the concrete formwork. The device occupies little space and does not require tension bolts to be arranged in the newly poured concrete, thus having strong practicality.
[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a device for reinforcing joints of a plain concrete wall, wherein a concrete formwork for pouring concrete is provided above the concrete wall, and the device is characterized in that: a plurality of joint reinforcement mechanisms are horizontally arranged at the joint between the concrete wall and the concrete formwork, the joint reinforcement mechanisms comprising a first steel plate vertically provided on the outside of the concrete wall and a second steel plate vertically provided on the outside of the concrete formwork, the top of the first steel plate being connected to the middle of the second steel plate via a third steel plate, and the first steel plate being provided with a first tension bolt and a second tension bolt for connecting to the concrete wall;

[0008] The above-mentioned device for reinforcing joints of plain concrete walls is characterized in that: the first steel plate and the second steel plate are both provided with first through holes for the first tension bolts to pass through, and the lower part of the first steel plate is provided with second through holes for the second tension bolts to pass through.
[0009] The above-mentioned device for reinforcing joints of exposed concrete walls is characterized in that the fourth steel plate is in an inclined state, and the high end of the fourth steel plate is connected to the second steel plate, and the low end of the fourth steel plate is connected to the first steel plate.
[0010] The above-mentioned device for reinforcing joints of plain concrete walls is characterized in that wooden wedges are provided between the horizontal wooden squares and the horizontal steel pipes.

In addition, the utility model occupies little space and does not need to set tension bolts in the newly poured concrete. It is highly practical and easy to promote and use.
[0013] 2. The utility model facilitates the connection between the middle of the first steel plate and the second steel plate and the concrete wall by setting the first pair of tension bolts, and facilitates the connection between the bottom of the first steel plate and the concrete wall by setting the second pair of tension bolts, thereby enhancing the integrity and stability of the joint reinforcement mechanism and having a good use effect.
