Abstract
Description
Technical Field
[0001] This utility model relates to the field of connectors, specifically a connection structure for precast concrete components. Background Technology
[0002] Precast concrete refers to concrete products made in a factory or on-site (not at the final design location); precast concrete is poured elsewhere rather than at the final construction site; fiber reinforcement can be used to enhance the reliability and toughness after cracking of precast concrete of different sizes and shapes.
[0003] Precast concrete components need to be assembled and spliced on site during use. Since the assembly of concrete components requires alignment, large equipment is needed to assist in the process. This assistance is required until the components are fixed, which results in a long usage time for the large equipment and affects the installation efficiency of subsequent components. Therefore, there is an urgent need for a device to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a connection structure for precast concrete components to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a precast concrete component connection structure, including a connector and a component body. The component body contains cast steel bars. The connector is sleeved on the outside of the component body, and a support plate is fixedly installed on the inside of the connector. Operating grooves are provided on both sides of the connector to facilitate steel bar connection. A grouting mechanism is installed on the outside of the connector for convenient grouting. In use, the connector is sleeved on the upper end of the lower component body, and the upper component body is moved to the inside of the top of the connector. At this time, the component body is supported by the support plate, thus the connector and component body are in a stable state. Therefore, large equipment is not required for control and fixation, and subsequent component body installation can be carried out. Then, the steel bars between the component bodies are connected and fixed, improving the installation efficiency of the component body.
[0006] Preferably, the grouting mechanism includes an injection component, a screw, a first pipe, a sealing plate, and a rubber gasket. The sealing plate is tightly attached to one side of the connector to facilitate sealing the operating groove position. The rubber gasket is bonded and fixed to one side of the sealing plate to facilitate sealing the position between the sealing plate and the connector. The screw moves through the sealing plate. The first pipe is embedded and fixed to one side of the sealing plate. The injection component is installed on one side of the sealing plate.
[0007] Preferably, the injection assembly includes a second pipe, a fixing block, a partition, and a groove. The second pipe is embedded and fixed on one side of the sealing plate, the fixing block is fixed on the outside of the second pipe, the partition is slidably disposed on the top of the fixing block, and the groove is opened on the partition. In use, after the steel reinforcement is connected, the sealing plate is fixed to the outside of the connector by screws to close the operation groove position. Then, the partition is pulled up to open the second pipe. The grouting pipe is then inserted into the second pipe to grout the inside of the connector until the grout overflows through the first pipe, indicating that the grouting is complete. Then, the partition is moved down to close the second pipe, thus completing the connection of the main body of the component.
[0008] Preferably, there are two support plates, which are symmetrically installed on the upper and lower sides inside the connector.
[0009] Preferably, one side of the screw is threaded through and disposed on the outside of the connector.
[0010] Preferably, the first pipe is an L-shaped pipe.
[0011] Preferably, the top end of the first pipe is higher than the bottom end of the upper component body.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. When using this utility model, the connector is sleeved on the upper part of the lower component body, and the upper component body is moved to the inside of the top of the connector. At this time, the component body is supported by the support plate, so the connector and the component body are in a stable state. Therefore, there is no need for large equipment to control and fix it, and the subsequent component body installation work can be carried out. Then the steel bars between the component bodies can be connected and fixed, which improves the installation efficiency of the component body.
[0014] 2. When using this utility model, after the steel bar connection is completed, the sealing plate is fixed to the outside of the connector by the screw to close the operation slot. Then, the partition is pulled up to open the second pipe. The grouting pipe is then inserted into the second pipe to grout the inside of the connector until the grout overflows through the first pipe. This indicates that the grouting is complete. Then, the partition is moved down to close the second pipe. At this point, the connection of the main body of the component is completed. Attached Figure Description
