High-strength building block and manufacturing method thereof

Abstract

The invention provides a high-strength building block and a manufacturing method thereof, and belongs to the field of prefabricated building blocks. The high-strength building block and the manufacturing method thereof solve the problem of low strength of existing prefabricated building blocks. The high-strength building block comprises a building block body, the building block body comprises twowall plates and two rib plates, and the two wall plates and the two rib plates enclose to form a heat preservation hole. The building block body is internally provided with a steel frame, the steel frame comprises a rectangular tubular steel cylinder, and the steel cylinder comprises four steel plates which are connected in sequence. The steel plates each have a plurality of fold lines which are parallel to each other in the longitudinal direction, and the steel plates are bent in a square wave shape along the fold lines. The outer side surfaces and the inner side surfaces of the steel platescorrespondingly form a plurality of outer mortar grooves and inner mortar grooves, and the four corners of the steel cylinder are separately bent and enclose to form four square tubular steel pipes. The steel frame further comprises two connecting seats and / or a plurality of connecting steel. The outer sides of the steel plates on the front side and the rear side are covered with connecting mortarand form the two wall plates, and the outer sides of the steel plates on the left side and the right side are covered with mortar and form the two rib plates. The building block has higher strength and is simple and convenient to manufacture.

Description

technical field [0001] The invention belongs to the technical field of prefabricated blocks, and relates to a high-strength block and a manufacturing method thereof. Background technique [0002] Existing prefabricated blocks are generally formed by pouring the mold frame as a whole, and the mold frame is disassembled after pouring, but the overall strength is low, resulting in a large amount of mortar for reinforcement, and at the same time adding ribs in the middle for reinforcement, resulting in a small internal insulation layer , can not achieve a good thermal insulation effect, and due to the characteristics of the mortar itself, it is easy to be brittle and cracked, and the stability of the wall after masonry is poor. [0003] The existing application number is 201710467178.0, a Chinese invention patent application titled "a reinforced block with a steel skeleton structure and its manufacturing method", which provides a reinforced block with a steel skeleton structure ...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the steel skeleton includes four reinforcement seats connected in sequence, there are too many connection parts, the overall structure is complex and the stability is poor;

[0005] 2. The strength of the middle part of the steel skeleton is relatively low, and it is easy to be squeezed and cause the mortar to be brittle, so the lateral impact resistance is poor;

[0006] 3. The reinforced seat includes I-beams connected in sequence, and the vertical structure is unstable, so the vertical bearing capacity is poor
