Embodiment Construction

[0023] Please refer to the attached figure 1 to attach image 3 Shown, the present invention is a kind of filling method of concrete in the joint area of ​​a partially combined prefabricated beam, which comprises the following process steps:

[0024] 1), prefabricated prefabricated beam 1, the prefabricated beam 1 is divided into a middle area and a joint area along its length direction, concrete 2 is poured in the middle area, the joint area is reserved, and no concrete is poured in advance. In this embodiment, the prefabricated beam 1 is specifically an H-shaped steel beam, which includes a web 11 and flanges 12 arranged on both sides of the web 11 ; the concrete 2 is located between the flanges 12 . The section of the beam in the middle area of ​​the H-shaped steel beam 1 is provided with a tie rod 6 , that is, the tie rod 6 connects the upper and lower flanges 12 and is buried in the concrete 2 .

[0025] 2) Pre-preparing the concrete filling block 3 according to the siz...

Abstract

The invention relates to a method for filling concrete in the node area of ​​a partially combined prefabricated beam, which includes the following process steps: 1) prefabricating the prefabricated beam, the prefabricated beam is divided into a middle area and a node area, pouring concrete in the middle area, and prefabricating the node area 2) Prepare concrete filling blocks in advance according to the size of the joint area; 3) Embed concrete filling blocks into the joint area after the prefabricated part of the combined prefabricated beam is assembled in place; 4) After embedding concrete filling blocks, place Welded small steel bars in the node area; 5), apply fine stone concrete on the outside of the concrete filling block and the small steel bar, so that the outer surface of the concrete in the node area is flush with the middle area. The present invention adopts the prefabricated concrete filling block to replace the on-site pouring concrete, so that the construction is convenient and fast, and the problems of grout leakage and the like do not occur.

Description

【Technical field】 [0001] The invention relates to a construction method of a prefabricated beam, in particular to a method for filling concrete in a joint area of ​​a partially combined prefabricated beam, and belongs to the technical field of construction methods of building components. 【Background technique】 [0002] The steel-concrete partial composite member is a new type of composite member proposed in Europe in the 1980s. The basic type of its section is to fill the flanges of H-shaped steel members with concrete. This composite member has the advantages of large bearing capacity, high rigidity, and good fire resistance, but it has not been practically applied in China at present. [0003] The steel-concrete part composite member is usually prefabricated in the factory with H-shaped steel, filled with concrete and completed with maintenance and processing. However, in order to facilitate the splicing of components, the joint area is usually not filled with concrete in...
