Embodiment Construction

[0013] The reinforcing method of improving the anti-seismic performance of stone structure house of the present invention, specific implementation steps are as follows (please refer to Figure 1-3 ):

[0014] (1) Determine the section size of the inner ring beam (generally 150-200mm in height and 100-150mm in width), and make a U-shaped stirrup 21 suitable for the size of the inner ring beam;

[0015] (2) drill holes on the first pimp stone 11 near the floor 3 bottom surface in the stone wall 1, utilize planting glue to implant the U-shaped stirrup 21 of diameter 8mm, the implantation length is not less than 80mm, the U-shaped stirrup 21 The layout spacing is preferably 200mm to 250mm; when the U-shaped stirrups 21 are implanted, four Φ12 longitudinal steel bars 22 should be placed in the U-shaped stirrups 21 in advance, and the bending and overlapping of the longitudinal steel bars at the corners of the ends The length is not less than 250mm;

[0016] (3) After the reinforc...

Abstract

The invention discloses a reinforcing method for improving earthquake resistance of stone structure buildings. The method is realized by the following scheme: closed cast-in-place reinforced concrete inner ring beams are poured around the bottom surface of the floor system of a stone structure building, and the stirrups of the closed cast-in-place reinforced concrete inner ring beams are anchored on the bar stone on the top of the stone wall of the stone structure building so that the inner ring beams, the stone wall and the floor system form an integer. Due to the scheme, the invention has the following advantages that: (1) with high strength, the granite bar stone can provide enough anchoring strength for the inner ring beams; and because of the large size and rough interface of the bar stone, close connection and tying action of the latterly added inner ring beams and the bar stone are facilitated so as to form a combined ring beam which plays a good role in enhancing the building integrity and the tying action between the longitudinal and transverse walls; (2) the stirrups of the inner ring beams also have functions of tying shear connectors and erecting longitudinal steel bars; and (3) the inner ring beams increase the support length of prefabricated floor plates or stone floor plates, reduce the calculation length and therefore enhance the integrity of the floor system as well as the bearing capability and collapse resistance of the floor system.

Description

technical field [0001] The invention relates to a reinforcement method for improving the anti-seismic performance of stone masonry structures. This method can be applied to the strengthening of weak earthquake resistance problems such as insufficient floor support length and poor integrity of stone structure buildings. Background technique [0002] There are a large number of stone-structure houses in the southeast coastal area. The load-bearing walls of these stone-structure houses are made of granite strips to build stone walls, and the floors are made of granite slabs (for village houses) or concrete prefabricated slabs (for urban houses or institutions). The main hidden dangers of seismic resistance in this structure are as follows: (1) The stone floor slab is easily broken due to its low bending capacity and natural cracks; The stone structure houses built in the early days were not equipped with ring beams, and the structural integrity of the earthquake resistance was...
