Abstract
The invention discloses a novel combined stone beam. The stone beam comprises a stone beam body, wherein a tensile region of the stone beam body is provided with a groove in the longitudinal direction of the stone beam body; a reinforcement material under a certain horizontal prestressing force is arranged in the groove in the longitudinal direction; the reinforcement material is fixed in the groove in a bonding way through a bonding material; and both ends of the reinforcement material are firmly fixed on both longitudinal ends of the stone beam body respectively through anchor devices. Compared with the prior art, the combined stone beam substantially increases the cracking moment, bending rigidity and anti-bending bearing capacity of the stone beam by embedding the high-strength tensile reinforcement material in the tensile region of the stone beam body and applying prestressing force and anchoring. Moreover, the combined stone beam can be applied in a beam-type stone-structure member of larger span and has the advantages of great width, high bearing capacity, no damages to stone-structure style and features and beauty, and the like; and therefore, the combined stone beam can be used in a newly-built stone-structure project and the reinforcement of an existing stone structure.
Description
Technical field
The present invention relates to a kind of combined stone beam, can be applicable to the strengthening reconstruction of beam type stone bridge, stone structure building, porch and isostructural construction of decorated archway and existing stone beam in the civil engineering.
Background technology
Stone structure is one of the most ancient form of structure of China, is widely used in bridge and building structure.Granite structural meterials great advantage is the compressive strength height, good endurance, and have natural quality advantage attractive in appearance.Stone structure has a long history in China's civil engineering, and foremost ancient times, the stone structure building comprised the The Zhaozhou Bridge (arch-type structure) of Zhao County, Hebei province, the Song dynasty Luoyang Bridge (girder structure) in Quanzhou, Fujian and the thing double tower of Kaiyuan Temple, Quanzhou etc.China some areas, particularly Fujian South Fujian Province still continue to adopt stone material to build the house because granite is drawn materials conveniently in most of small towns.Also there is significant disadvantages in stone material, and is lower such as tensile strength, material is crisp and often have natural crack.Therefore, stone material is often used for compressed member on engineering is used, such as wall, post and arch etc.Though also have as flexural members such as beam slabs, higher because of the needs cross section, often seem too heavy, not only anti-bending bearing capacity is lower, and has the danger of bigger brittle fracture, thereby has limited the range of application of granite building material.
Summary of the invention
The purpose of this invention is to provide a kind of novel combined stone beam that increases substantially cracking bearing capacity, anti-bending bearing capacity and bending rigidity.
Technical scheme of the present invention is such: a kind of novel combined stone beam, comprise stone beam body, the tensile region of this stone beam body vertically offers groove along stone beam body, vertically be equipped with in this groove and applied prestressed muscle material, this muscle material is fixed in this groove by the binding material bonding, and the two ends of this muscle material are anchored on vertical two ends of above-mentioned stone beam body respectively by ground tackle.
Above-mentioned groove is square groove or the U-lag that size is about 2 times of the diameters of above-mentioned muscle material.
Above-mentioned muscle material is all higher carbon fibre bar of tensile strength and modulus of elasticity or high-strength steel steel strand.
Above-mentioned binding material is modified epoxy structure glue or the cement-based grout material with high-strength adhesion stress.
After adopting such scheme, compared with prior art, the present invention has following advantage: (1) embeds the anti-bending bearing capacity that the muscle material can improve the stone beam greatly in the Shi Liang tensile region, improved the brittle fracture character of stone beam, thereby expanded the range of application of stone structure, made application become possibility than large span stone beam.(2) by in the muscle material, applying proper level prestressing force, increase substantially the cracking moment and the bending rigidity of stone beam, effectively improved the functional performance of combined stone beam.(3) effectively suppress the expansion in crack, stone beam curved scissors district, thereby improved the shear behavior of stone beam.(4) by the reasonable combination of material, the compressive strength of stone material and the tensile strength of muscle material are given full play to, realize the mutual supplement with each other's advantages of material.

The specific embodiment
A kind of novel combined stone beam of the present invention, as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, comprise stone beam body, stone beam body is the complete granite beam 1 that meets the engineering physical dimension in the present embodiment, a side that is positioned at its tensile region 10 on the stone beam 1 vertically offers square groove 11 along stone beam 1, vertically be equipped with high-strength muscle material 3 in the square groove 11, high-strength muscle material 3 applies prestressing force by special-purpose tensioning equipment, high-strength muscle material 3 applies prestressed prestressing force level and calculates definite according to instructions for use, high-strength muscle material 3 is fixed in the square groove 11 by binding material 2 bondings, and the two ends of high-strength muscle material 3 are anchored in vertical two ends of Shi Liang 1 respectively by ground tackle 5, finally make Shi Liang 1, binding material 2 and high-strength muscle material 3 are combined into can stressed jointly combined stone beam.
Wherein, high-strength muscle material 3 can be used tensile strength and all higher carbon fibre bar or the high-strength steel steel strand of modulus of elasticity; The size of square groove 11 is about high-strength muscle material 3 diameters or thickness 2 times, and the size at vertical two ends of square groove 11 correspondingly strengthens according to the diameter of ground tackle 5, and binding material 2 can adopt high-strength binding materials such as modified epoxy structure glue or cement-based grout material; Ground tackle 5 is telescopic ground tackle or clipping ground tackle.
Novel combined stone beam of the present invention, concrete constructure scheme is as follows:
(1), calculates diameter and the quantity of determining required muscle material 3 by anti-bending bearing capacity, to determine the size and the quantity of required plane cutter groove according to sectional dimension, the span of stone beam 1 with bear the load size.
(2), determine the level of stretch-draw prestressing force according to requirement of stone beam 1 control of crack width and amount of deflection control requirement.
(3) side that is positioned at its tensile region 10 on stone beam 1 is vertically dug the square groove 11 that the cutter size is about 2 times of muscle material 3 diameters along stone beam 1, and the size at vertical two ends of square groove 11 correspondingly strengthens according to the diameter of ground tackle 5;
(4) in square groove 11, lay muscle material 3, to the predetermined stress level, and the two ends of muscle material 3 are anchored in the stone beam end by ground tackle 5 by special-purpose tensioning equipment stretch-draw muscle material 3.
(5) paste U.S. line paper on square groove 11 limits to prevent that filling out filling binding material 2 pollutes stone materials.
(6) insert binding material 2 in square groove 11, the consumption of binding material 2 exceeds with the notch a little less than square groove 11, and the levelling glue face.For needs attractive in appearance, the glue face also can be lower than Shi Liang 1 surface, to form some recessed formula lines at the bottom of beam.
(7) tear U.S. line paper off, leave standstill to the design strength of binding material 2 and can lift use.
