Abstract
The invention belongs to the technical field of structural engineering, and relates to a novel masonry structure with high debris flow impact resistance. The novel masonry structure comprises conventional longitudinal and transverse wall structural systems. Structural columns are arranged at joints of longitudinal and transverse walls, ring beams are arranged at elevation positions of roofs and foundation tops, and crossed light steel diagonal bracings are arranged on the inner sides of wall bodies where front impact of debris flow is borne. The novel masonry structure has the advantages that the novel masonry structure is based on the traditional masonry structure, conventional structural measures that the structural columns are arranged at the joints of the longitudinal and transverse walls and the ring beams are arranged at the roofs are adopted, the novel masonry structure is different from the traditional masonry structure in that the oblique crossed light steel diagonal bracings are arranged on the inner sides of the wall bodies where the front impact of the debris flow is borne, the light steel diagonal bracings are anchored in the structural columns and the ring beams, accordingly, the external plane stiffness of the wall bodies can be enhanced, and the debris flow impact resistance of the wall bodies can be improved.
Description
Technical field
The invention belongs to technical field of structural engineering, be specifically related to a kind ofly resist the strong new masonry structure of mud-rock-flow-impact ability, compared with ordinary masonry structure, there is the ability of stronger opposing mud-rock-flow-impact.
Background technology
The feature such as mud-rock flow has emergentness and flow velocity is fast, flow is large, matter content is large and destructive power is strong, China western mountainous areas is district occurred frequently and the severely afflicated area of mud-stone flow disaster, and comparatively major disaster all occurred on the ground such as Sichuan, Yunnan, Tibet, Gansu and Shaanxi.And in these areas, because of the restriction by orographic condition, many cities and towns are often selected on the smooth open old debris fans of physical features; In addition the impact of mud-rock-flow-impact do not considered by the building structure that conventional design is built, and the ability of opposing mud-rock-flow-impact is poor; And limit by economic capability, most of villages and small towns masonry house belongs to self-built housing, and do not have construction measure that is reasonable, specification, rural house building materials quality is poor, and building technology falls behind, and anti-geological disaster ability is general lower.The ability of conventional building structure form opposing mud-rock-flow-impact is poor, especially masonry house is subject to the body of wall of mud-rock flow frontal impact often to occur the situation of total Collapse, cause a large amount of casualtiess and property loss, therefore a kind of is necessary for the design of mud-rock-flow-impact feature, rural house new structure that opposing mud-stone flow disaster ability is strong.
Summary of the invention
In order to overcome external wall of house in the low shortcoming of out of plane stiffness, object of the present invention is that providing a kind of resists the strong new masonry structure of mud-rock-flow-impact ability.
The a kind of of the present invention's proposition resists the strong new masonry structure of mud-rock-flow-impact ability, comprise vertical wall 2 and cross wall 3, basis, vertical wall 2 connect to form masonry structure with cross wall 3, be provided with closed constructional column 4 and collar tie beam 5 at vertical wall 2 with cross wall 3 junction, described closed constructional column 4 and collar tie beam 5 are positioned on the described building structure cross wall parallel with mud-rock-flow-impact direction 3; The light steel diagonal brace 6 of intersection is had by vertical wall 2 disposed inboard of mud-rock flow frontal impact at building structure, described light steel diagonal brace 6 two ends anchor into constructional column 4 and the collar tie beam 5 of vertical wall 2 and cross wall 3 junction respectively, to strengthen the out of plane stiffness of building structure under mud-rock-flow-impact effect, and by the impact force of mud-rock flow by indulging wall 2 with light steel diagonal brace 6 through on cross wall 3, resisted the percussion of mud-rock flow by the flat in-plane stiffness that cross wall 3 is larger, thus improve the ability of house by mud-rock-flow-impact.
In the present invention, the walling unit of described vertical wall 2 and cross wall 3 adopts sintering stalk brick 1, stalk brick is a kind of green brick material of refuse reclamation, and there is the feature of lighter weight while ensureing pressurized, the mechanical strength such as being cut, under mud-rock-flow-impact, collapsing of walling unit can not cause very large injury to personnel in house and property.
Beneficial effect of the present invention is:
The present invention intersects light steel diagonal brace by body of wall disposed inboard, improve the outer rigidity of the wall plane that is hit, to ensure that body of wall can not entirety collapse under mud-rock-flow-impact, percussion is conducted to the cross wall parallel with mud-rock-flow-impact action direction by diagonal brace with the connection of constructional column, collar tie beam, the flat in-plane stiffness stronger by cross wall and good globality resist the percussion of mud-rock flow simultaneously; Materials for wall adopts the sintering stalk brick with lightweight, environmental protection feature simultaneously, and overall economic efficiency is good.

Detailed description of the invention
Below in conjunction with implementing shown in accompanying drawing, the present invention will be further described.
Embodiment 1: Fig. 1 is building structure top view, and wherein the disposed inboard of vertical wall 2 has the light steel diagonal brace 6 of intersection, and the arrangement form of the light steel diagonal brace 6 of intersection is as Fig. 2 ~ Fig. 4.After basis, vertical wall 2 have been built by laying bricks or stones with cross wall 3, constructional column 4 reinforcing bar is placed in 2 wall junctions in length and breadth, the end of the light steel diagonal brace 6 intersected is placed on collar tie beam 5 with in constructional column 4 joint cores, the light steel diagonal brace 6 of intersection is arranged according to the different situations of Fig. 2 ~ Fig. 4 in vertical wall 2 inside simultaneously.While constructional column 4 and collar tie beam 5 concreting, cross support end is also cast in concrete, thus the two ends of cross support anchor into respectively roofing absolute altitude place collar tie beam, the joint cores of collar tie beam and constructional column.
