Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention.

Example (b):

referring to fig. 1-4, the green and environment-friendly load-bearing precast beam comprises a precast beam body shell 1, wherein an i-shaped groove is formed in the beam body shell 1, an i-shaped steel 3 is assembled in the i-shaped groove, and the two beam body shells 1 are connected through the i-shaped steel 3;

at this moment, when the load-bearing precast beam is installed, one end of the I-steel 3 is inserted into the I-shaped groove of one of the beam body shells 1, and then the other end of the I-steel 3 is inserted into the I-shaped groove of the other beam body shell 1, so that the two beam body shells 1 are assembled, the assembling processes of the precast beam can be reduced, and the construction efficiency is improved.

In order to avoid the left-right sliding of the beam body shell 1 in the I-shaped grooves, the number of the I-shaped grooves is preferably two, the I-shaped grooves are respectively arranged at two ends of the beam body shell 1, and at the moment, after the I-shaped steel 3 is inserted into the two I-shaped grooves, the two I-shaped grooves are spliced to form a complete I-shaped groove to limit the I-shaped steel 3.

Referring to fig. 1 and 3, two limiting inner shells 2 are arranged inside a beam outer shell 1, two limiting inner shells 2 prefabricated in the same manner are arranged inside the limiting inner shells 2, and groove bodies formed inside the two limiting inner shells 2 are i-shaped grooves.

Referring to fig. 1 and 3-4, in order to ensure the stability of the i-beam 3 installed inside the i-beam channel, a cast-in-place concrete cushion 4 is filled inside the limiting inner shell 2, and a gap between the limiting inner shell 2 and the i-beam 3 is filled with the concrete cushion 4, so that the connection stability between the limiting inner shell 2 and the i-beam 3 is effectively improved.
