Embodiment 1

[0024] like Figure 1-Figure 4 A reusable wall low-cycle repeated loading test foundation is shown, which includes a base 1, and a rectangular groove 2 is opened on the top surface of the base 1, and the size of the rectangular groove 2 is larger than that of the cross-section of the wall specimen. Dimensions, the base 1 adopts a steel structure with sufficient rigidity, which can ensure the durability of the base 1. On the side walls around the base 1 are pre-embedded several horizontal sleeves 6, one end of the sleeve 6 communicates with the outside world, and the other end of the sleeve 6 passes through the side wall of the base 1 and communicates with the inner cavity of the groove 2. A fastening bolt 5 is screwed inside the casing 6 .

[0025] Two horizontal sleeves 8 are pre-embedded on the base 1, and the two sleeves 8 are symmetrical about the centerline of the length direction of the groove 2. The length direction of the sleeve 8 is perpendicular to the length direct...

Abstract

The invention discloses a reusable wall low-cycle repeated loading test foundation, which comprises a base. A rectangular groove is formed in the top surface of the base. A plurality of horizontally arranged casing pipes are embedded in the side walls of the base. One end of each casing pipe is communicated externally and the other end of each casing pipe is communicated with the inner cavity of the groove through the side walls of the base. Fastening bolts are screwed into the casing pipes. According to the invention, solid round steel rods pass through the casing pipes and connecting holes reserved in a wall test piece to fix the wall test piece with the base preliminarily; the fastening bolts are screwed and a first anchoring plate and a second anchoring plate are supported tightly on the wall test piece, so that the wall test piece is fixed in the groove firmly. The base can be reused to avoid repeated making of a reinforced concrete base, so that the test materials and the scientific research cost are saved; the test cycle is reduced; and concrete wastes after the test completion are reduced.

Description

Technical field: [0001] The invention relates to a wall body test foundation, in particular to a reusable wall body low cycle repeated loading test foundation. Background technique: [0002] The low-cycle repeated load test is a commonly used test method in the field of seismic resistance of building structures, which has the advantages of economy and practicality. In the past, in the low-cycle repeated load test of the new wall, each wall specimen needs to pour a reinforced concrete foundation separately. During the test, the specimen foundation is firmly fixed on the table, and then a horizontal load is applied to the top of the specimen. Because this method needs to make a large number of reinforced concrete foundations, it increases the cost, is time-consuming and labor-intensive, and the reinforced concrete foundations cannot be reused after the test, and a lot of concrete waste will be generated in the laboratory. Invention content: [0003] The object of the presen...
