Abstract
The utility model provides a connecting piece between PCF board and prefabricated outer wall, including pre-buried sleeve and connecting piece main part, pre-buried sleeve sets up respectively in PCF board and outer wall, the lower extreme is the L type by angle steel welded forming in the connecting piece main part to connect through the vertical angle steel of tip welding, be equipped with the round hole on the vertical angle steel, the main part uses bolted connection pre-buried sleeve through the round hole. The utility model discloses simple structure can be according to the on-the-spot preparation of actual engineering size, and is simple and convenient.
Description
Technical Field
The utility model relates to a construction field, concretely relates to connecting piece between PCF board and prefabricated outer wall.
Background
The assembly type structure is a structural system which is mainly pushed by the current government, but various problems occur during construction and installation due to the fact that the specifications and the drawing sets of the current assembly type building are not complete and the experience of the domestic assembly type building is seriously poor. At present, the high-rise residence frequently adopts an assembly type structure, the installation of a prefabricated outer wall is always the difficult point of the installation of the assembly type structure, particularly, the PCF plate has light dead weight and is weakly connected with a main structure, so that the PCF plate often has the problems of cracks and the like when a corner cast-in-place edge component is poured. As shown in fig. 1, at present, L-shaped steel plates are mostly used as connectors, but the connectors are easy to bend, which easily causes unevenness of PCF and prefabricated exterior wall, and is not helpful for controlling PCF plate cracks.
SUMMERY OF THE UTILITY MODEL
The utility model provides a connecting piece between PCF board and prefabricated outer wall to solve traditional L type connecting piece and easily bend and lead to PCF board and prefabricated outer wall unevenness to cause fissured problem.
The utility model provides a connecting piece between PCF board and prefabricated outer wall, including pre-buried sleeve and connecting piece main part, pre-buried sleeve sets up respectively in PCF board and outer wall, the lower extreme is the L type by angle steel welded forming in the connecting piece main part to connect through the vertical angle steel of tip welding, be equipped with the round hole on the vertical angle steel, the main part uses bolted connection pre-buried sleeve through the round hole.
Preferably, an internal thread is arranged inside the embedded sleeve.
Preferably, the specification of the angle steel is ∠ 50 × 50 × 5.
The utility model has the advantages that: the utility model discloses a pre-buried sleeve on PCF board and prefabricated outer wall treats PCF board hoist and mount location back, adopts the bolt to be connected connecting piece and PCF board and prefabricated outer wall. The utility model discloses strengthen the rigidity of connecting piece greatly, effectively controlled the removal of PCF board, prevented the fissured production of PCF board. The utility model discloses simple structure can be according to the on-the-spot preparation of actual engineering size, and is simple and convenient.
Drawings
Fig. 1 is a prior art L-shaped steel plate connector.
Fig. 2 is a schematic structural diagram of the present invention.
Fig. 3 is a schematic view of the usage state of the present invention.
The connecting piece comprises a connecting piece body 1, a circular hole 2, a bolt 3, a PCF plate 4 and an outer wall 5.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to specific embodiments.
Examples
According to fig. 1 ~ 3, the utility model provides a connecting piece between PCF board and prefabricated outer wall, including pre-buried sleeve and connecting piece main part 1, pre-buried sleeve sets up respectively in PCF board 4 and outer wall 5, the lower extreme is the L type by angle steel welded forming about connecting piece main part 1 to connect through the vertical angle steel in tip welding, be equipped with round hole 2 on the vertical angle steel, the main part uses bolt 3 to connect pre-buried sleeve through round hole 2.
Further, internal threads are arranged inside the embedded sleeve.
Further, the specification of the angle steel is ∠ 50 multiplied by 5.
The specific working process is as follows:
firstly, the prefabricated outer wall around the PCF board is installed, and the positioning of the prefabricated outer wall is checked.
And secondly, completing the lifting of the PCF plate, and calibrating whether the PCF is accurately positioned.
And thirdly, cutting off the heat-insulating layer at the position of the embedded sleeve on the PCF plate to expose the positions required by the embedded sleeve and the connecting piece.
And fourthly, aligning the connecting piece to the embedded sleeve and fixing the connecting piece by using a bolt.
The above description is only an example of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
Claims (3)
