Point-supported PC wallboard connecting device

Abstract

The invention relates to a point-supported PC wallboard connecting device, belonging to the technical field of connecting devices or parts special to walls. The point-supported PC wallboard connecting device comprises a pre-burying pendant, a bolt sleeve and a base, wherein the pre-burying pendant comprises a pre-burying mechanism and a hanging mechanism, one side of the pre-burying pendant is connected into a PC wall board through the pre-burying mechanism, the other side of the pre-burying pendant is movably connected with the bolt sleeve and the base through the hanging mechanism and mutually moves relative to the bolt sleeve and the base through the hanging mechanism so as to change up-down, left-right and front-rear positions. The point-supported PC wallboard connecting device is applied to the mounting and connecting of the PC wallboards and the like, and has the advantages of firmness, accuracy, safety, environmental friendliness, convenience, high efficiency and the like.

Description

technical field [0001] The invention relates to a point-supported PC wallboard connection device, which belongs to the technical field of connection devices or components specially used for walls. Background technique [0002] With the country's vigorous promotion of prefabricated steel structure buildings and many restrictions on the application of glass curtain walls in building exterior decoration, prefabricated concrete (PC) exterior wall panels are more and more widely used in prefabricated steel structure buildings. Due to the high gravity mass density of PC wallboard (about 24~28kg / m 3 ), and the reinforced concrete structure should be supported under pressure, so the application of external PC wall panels in domestic and foreign buildings is becoming more and more common. , the upper connection node can slide to absorb the displacement between the main layers; the point support method is mainly divided into two forms: translation type and rotation type. In practica...

Problems solved by technology

In practical applications, the traditional method of the load-bearing joints under the external PC wall panels is to adopt the separate type of load-bearing and wind-resistant supports, that is, two thickened corbels are added on the two sides near the lower end of the PC board as load-bearing supports. There is also an independent connector for wind-resistant support. The load-bearing corbel structure of this connection method needs to partially thicken the PC plate, which increases the difficulty of plate processing and mold costs; after the adjustment of the independent connector of the wind-resistant support, a large number of on-site welding is required. The construction work comes to the final fixation, and a large number of welding operations on site reduce the construction efficiency of the construction project, which is neither safe nor environmentally friendly

At present, in Japan and some parts of China, there are also a lot of ways to combine load-bearing and wind-resistant supports into one, no need to add plate corbel structures, no need to thicken, but the adjustment of the load-bearing height and direction is adjusted by adding steel pads. On-site construction errors are various in size, and the specifications and types of steel pads are fixed, resulting in unsatisfactory adjustment performance and difficult to adjust and position accurately

There are also some bolts to adjust the height direction of the positioning, the height adjustment is convenient, but there is always a limited adjustment space for the adjustment of the front and rear directions or the left and right directions, which is not ideal. It has not achieved the true three-way adjustable, and there are certain defects.
