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
The present invention relates to a kind of reinforcement means that improves the stone masonry structure anti-seismic performance.This method can be applicable to the weak problem of antidetonations such as stone structure house floor bearing length deficiency, globality difference is reinforced.
Background technology
There are a large amount of stone structure houses in the southeastern coastal areas, and the carrying wall of these stone structure houses adopts the granite rectangular slab of stone to build stone walling by laying bricks or stones, and superstructure adopts granite slabstone (villages and small towns private residence) or concrete prefabricated board (cities and towns dwelling house or public institution room).The main antidetonation hidden danger that this structure exists is as follows: (1) Shilou County plate is because its anti-bending bearing capacity is low and often have natural crack, very easily a brittle failure; (2) Shilou County's plate and concrete prefabricated board all belong to precast assemble floor, and these are built stone structure house in early days and all do not dispose collar tie beam, and the structural seismic globality is relatively poor; (3) floor member is coming off under big shake easily within the walls bearing length deficiency, has the hidden danger that collapses.
Therefore, be badly in need of the relevant seismic hardening technology of invention stone structure, to satisfy the needs of the stone structure strengthening reconstruction that southeastern coast has a large capacity and a wide range.The reinforcing technique that solves above-mentioned stone structure house superstructure potential safety hazard comprises: (1) slabstone superstructure anti-bending bearing capacity reinforcing technique; (2) stone structure superstructure antidetonation globality reinforcing technique." reinforcement means of slabstone superstructure " (submit applications) that slabstone superstructure anti-bending bearing capacity reinforcing technique can adopt the applicant to propose.
Summary of the invention
The purpose of this invention is to provide a kind of reinforcement means with good consolidation effect, raising stone structure house anti-seismic performance with strong points.
To achieve these goals, the present invention adopts following technical scheme:
Improve the reinforcement means of stone structure house anti-seismic performance, be achieved by the following scheme:
Around the bottom surface of the superstructure of stone structure house, pour into a mould collar tie beam in the closed type cast-in-situ steel reinforced concrete, and the stirrup of collar tie beam is anchored on the stone walling top rectangular slab of stone of stone structure house in this closed type cast-in-situ steel reinforced concrete, and collar tie beam and stone walling and superstructure form an integral body in making.
Above-mentioned stirrup adopts the u tie muscle of implanting the stone walling top rectangular slab of stone by bar planting glue.
After adopting such scheme, the present invention has following advantage: (1) granite rectangular slab of stone intensity height, the enough anchoring strengths of collar tie beam in can providing, add that rectangular slab of stone size is big, interface roughness, collar tie beam and the tight drawknot of the rectangular slab of stone, acting in conjunction in adding after being convenient to form the combination collar tie beam, have played enhancing house globality and wall drawknot effect in length and breadth well; (2) stirrup of interior collar tie beam plays the effect of drawknot shear connector and the upright longitudinal reinforcement of frame simultaneously; (3) interior collar tie beam has increased the bearing length of precast floor slab or Shilou County's plate, reduces calculated length, has not only strengthened the globality of superstructure, has also strengthened the bearing capacity and the anti-ability of caving in of superstructure simultaneously; (4) the inventive method adopts effect better with " reinforcement means of slabstone superstructure " of previous submit applications in the lump, and the anti-seismic performance of stone structure house will be improved by a larger margin.
Description of drawings
Fig. 1 is the structural representation of the stone structure house of collar tie beam in being provided with among the present invention;
Fig. 2 is the A-A cut-away enlarged view of Fig. 1;
Fig. 3 is the B-B cut-away enlarged view of Fig. 1.
The specific embodiment
The reinforcement means of raising stone structure house anti-seismic performance of the present invention, concrete implementation step following (seeing also Fig. 1-3):
(1) (generally high 150~200mm is wide by 100~150mm), makes the u tie muscle 21 of collar tie beam size in being suitable for to determine inner ring beam section size;
(2) at the u tie muscle 21 of stone walling 1 near the bar planting glue implanted diameter 8mm that holes on the first leather strap stone 11 of superstructure 3 bottom surfaces, utilizes, implant length and be not less than 80mm, the arrangement pitch of u tie muscle 21 is that 200mm~250mm is advisable; When implanting u tie muscle 21, should in u tie muscle 21, shelve the longitudinal reinforcement 22 of 4 Φ 12 in advance, longitudinal reinforcement is not less than 250mm in the bending lap length of end corner;
(3) treat the bar planting adhesive curing after, colligation location longitudinal reinforcement 22, the reinforcing cage of collar tie beam 2 in forming;
(4) template that the collar tie beam concrete is used in the fabrication and installation cast, and carry out reasonable supporting;
(5) on the superstructure 3 of the good template of supporting, drill through the blanking hole 31 that fluid concrete is used;
(6) by blanking hole 31 cast self-compaction pea gravel concretens (or common pea gravel concreten) 23, form the interior collar tie beam 2 that is anchored on the stone walling 1.
Claims (2)
1. improve the reinforcement means of stone structure house anti-seismic performance, it is characterized in that, be achieved by the following scheme: around the bottom surface of the superstructure of stone structure house, pour into a mould collar tie beam in the closed type cast-in-situ steel reinforced concrete, and the stirrup of collar tie beam is anchored on the stone walling top rectangular slab of stone of stone structure house in this closed type cast-in-situ steel reinforced concrete, and collar tie beam and stone walling and superstructure form an integral body in making.
2. the reinforcement means of raising stone structure house anti-seismic performance according to claim 1 is characterized in that: above-mentioned stirrup adopts the u tie muscle of implanting the stone walling top rectangular slab of stone by bar planting glue.
