Abstract
The utility model relates to an internal prestress sintered clay brick building body structure, which belongs to the technical field of anti-seismic reinforcement. The internal prestress sintered clay brick building body structure comprises a wall body and prestress steel bar anchor rods, wherein the wall body is formed by sintered clay bricks, the prestress steel bar anchor rods transversely and uniform pass through the wall body, the two ends of the prestress steel bar anchor rods are subjected to prestress anchoring through pad plates and anchor bolts, and mortar is filled between the prestress steel bar anchor rods and holes of the sintered clay bricks. The internal prestress sintered clay brick building body structure has the advantages that the anti-crack and anti-shearing performance of the wall body is effectively improved, the crack and the crack development of the wall body are restrained, and the anti-seismic performance of the building body structure is improved.
Description
Technical field
The utility model relates to a kind of inner prestressing force sintered clay brick brick masonry structure, belongs to seismic hardening technical field.
Background technology
Research both at home and abroad shows, masonry structure is applied to prestressing force, can improve masonry structure properties of materials, improve cracking resistance, anti-seismic performance and the shear-carrying capacity of masonry structure, and can make existing building after prestressed reinforcement and transformation, meet follow-up safe handling requirement and antidetonation, energy-conservation and environmental requirement.China is that masonry structure is applied maximum countries in the world, especially sintered clay brick specially but to prestressing force masonry research compare and relatively lag behind with the world.Nineteen ninety-five to 1998 Nian Jian， professor Luo Wankang of Chongqing Univ. of Architecture has carried out the experimental study of configuration prestressed reinforcement to brick masonry wall sheet, result of the test shows, even if applied very low prestressing force σ
0=0.0852MPa (σ
0for the initial compressive stress of prestressing force to body of wall), without the blank wall of window opening, than the cracking load of non-prestressed wall, improved 30%, ultimate load improves 25%.For the prestressing force wall in the hole of windowing, applying prestressing force, be σ
0=0.141MPa and σ
0in two kinds of situations of=0.282MPa, compare with the non-prestressed hole wall of windowing, cracking load has improved respectively 27% and 40%, and ultimate load has improved respectively 18% and 60%, and ductility ratio has improved 8% and 25%.
But with abroad compare, China about prestressing force masonry structure, be also in conceptual phase, also do not enroll corresponding standard and carry out practical stage.Abroad from the prestressing force masonry structure system research starting eighties, the state such as Britain and New Zealand does a lot of work, with reference to prestressed reinforced concrete construction design principles, many prestressing force masonry brick houses and retaining wall have been built, summing up on the basis of test and engineering practice, method for designing has been included in to Code for design of masonry strucres.U.S.'s masonry standard association meeting (MSJC) in 1999, " the masonry structure norm of construction " of having listed prestressing force masonry in new revision (ACI530/ASCE5/TMS402) in.
China to the rational computational methods of the reinforcing of masonry, prestressed stretch-draw, anchoring, optimum prestress degree and the problems such as method that prevent Relaxation of prestressing also need to study further, test and engineering practice, for this technology of promotion and application creates conditions.
Utility model content
The utility model is for the problems referred to above, a kind of inner prestressing force sintered clay brick brick masonry structure has been proposed, mainly by entering prestressed reinforcement anchor pole sintered clay brick wall is mid-, and carry out pressure grouting, tension reinforcing steel bar carries out anchoring again, form prestressing force grouting rock bolt sintered clay brick structure is carried out to seismic hardening, wherein prestressed reinforcement anchor pole adopts the form being laterally evenly arranged.The problem that it has effectively solved wall crazing and has improved Seismic Bearing Capacity.
To achieve these goals, the utility model has been taked following technical scheme:
A kind of inner prestressing force sintered clay brick brick masonry structure, comprise body of wall and prestressed reinforcement anchor pole, it is characterized in that: described body of wall consists of sintered clay brick, described prestressed reinforcement anchor pole is laterally evenly arranged in body of wall, the two ends of described prestressed reinforcement anchor pole, by backing plate and crab-bolt prestress anchoraging, are perfused with mortar between described prestressed reinforcement anchor pole and the hole of sintered clay brick.
On described prestressed reinforcement anchor pole, be arranged with thin-wall steel tube or plastic pipe.
In described body of wall, every 1～2 building block, be provided with vertical reinforced mesh.
Described vertical reinforced mesh adopts φ 6 reinforcing bars to be welded.
Described prestressed reinforcement anchor pole adopts the prestressed reinforcement of φ 16～φ 18.
The longitudinal pitch of described prestressed reinforcement anchor pole is 400mm～600mm.
Described prestressed reinforcement anchor pole two ends anchorage length is not less than 60mm.
Beneficial effect: the utility model can improve body of wall cracking resistance, shear behavior effectively, suppresses wall crazing, suppresses crack progressing, improves the anti-seismic performance of masonry structure, particularly to existing masonry building seismic hardening, can effectively improve Seismic Bearing Capacity.

Fig. 2 is the anchor rod anchored figure that looks of prestressed reinforcement in Fig. 1.
In figure, 1: backing plate; 2: body of wall; 3: prestressed reinforcement anchor pole; 4: crab-bolt.
The specific embodiment
As shown in Fig. 1～Fig. 2, the specific embodiment of the present utility model is as follows:
A kind of inner prestressing force sintered clay brick brick masonry structure, comprise body of wall 2 and prestressed reinforcement anchor pole 3, body of wall 2 consists of sintered clay brick, and prestressed reinforcement anchor pole 3 adopts the prestressed reinforcement of φ 16～φ 18 and is laterally evenly arranged in body of wall 2, and longitudinal pitch is 400mm～600mm.The two ends of prestressed reinforcement anchor pole 3 are by backing plate 1 and crab-bolt 4 prestress anchoragings, and two ends anchorage length is not less than 60mm.On prestressed reinforcement anchor pole 3, be arranged with thin-wall steel tube or plastic pipe, between the hole of itself and sintered clay brick, be perfused with mortar.In body of wall 2, every 1～2 building block, be provided with vertical reinforced mesh, vertically reinforced mesh adopts φ 6 reinforcing bars to be welded.
Its concrete reinforcement means comprises the steps:
Step 1: the body of wall 2 that adopts grouting rock bolt to reinforce to need according to design drawing carries out unwrapping wire and along cross wall to being evenly arranged hole;
