Abstract
A carbon fiber pin used for ensuring cooperative operation between a carbon fiber sheet and a masonry structure is made by rolling a carbon fiber cloth tape into the shape of a pin rod, and is characterized in that the rod of the carbon fiber pin penetrates the masonry with two ends exposed outside the masonry; and two ends of the pin rod are sheared into strips which expand in the shape of petal and are stuck to the carbon fiber cloth tape stuck on the masonry to be fixed. The carbon fiber pin is used with the carbon fiber cloth tape to reinforce the masonry structure, so that the integral anti-seismic property is reinforced, and the technical problems that the carbon fiber cloth tapes on two surfaces of the masonry lack of organic and firm connection and cannot ensure the cooperative operation between carbon fiber sheet and masonry structure is solved.
Description
Technical field
The utility model relates to a kind of reinforcing masonry structure, improves the part that reinforces the connection of masonry anti-seismic performance.
Background technology
The traditional Shockproof reinforcing method of masonry structure body of wall adopts the ferro-cement surface layer usually or sprays cast-in-situ reinforced concrete slab wall (common name clamping plate wall) in conjunction with the method for setting up reinforced concrete structural column and collar tie beam; The bearing capacity that these methods can improve structure to a certain extent improves anti-seismic performance, satisfies the requirement of predetermined function of use.But there is long construction period in these reinforcement means, increases structure and ground load, take architectural space and cause existing line equipment to be shifted, to invest shortcomings such as big in a large number.Existing method with carbon fiber strap reinforcing masonry structure because the carbon fiber strap on masonry two sides lacks organic connections, therefore can not ensure carbon fiber strap and masonry structure collaborative work.
The utility model content
The utility model proposes a kind of carbon fiber pin that is used to ensure carbon cloth and masonry structure collaborative work, the carbon fiber strap that solve the masonry two sides lacks organic connections, can not ensure the technical problem of carbon fiber strap and masonry structure collaborative work.
The technical solution of the utility model is as follows:
A kind of carbon fiber pin that is used to ensure carbon cloth and masonry structure collaborative work, by carbon cloth roll coil of strip system form the nail shaft-like, it is characterized in that: the nail bar of described carbon fiber pin penetrates masonry, two ends are exposed at the masonry outside, the two ends of nail bar is the strip shape that is cut into, and the carbon fiber strap that the end silver is petal expansion, paste above with masonry is pasted fixing.
Described end silver can be three to eight.
A reinforcing bar can be arranged in the nail bar of described carbon fiber pin or a pipe is arranged.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, make easily, easy construction, carbon fiber pin both ends stick on the carbon fiber strap outside of reinforcing masonry structure in the form of sheets, the carbon fiber strap and the masonry structure that can effectively ensure the masonry two sides fuses, collaborative work, make carbon cloth belt restraining body of wall, effectively stop carrying out of masonry structure wall body slit, improved the stress of masonry structure body of wall, and improved shear-carrying capacity, avoided when load reaches capacity state, owing to the brittle fracture of brickwork causes integrally-built unexpected destruction.This method easy construction, duration be short, do not occupy former have living space, do not increase structure and ground load, small investment.Be applicable to the masonry structure that needs reinforcement.Need reinforcement and transform masonry, the masonry of two body of wall intersections, the masonry of body of wall corner and the masonry at contiguous door and window hole place that masonry comprises masonry, body of wall and the post intersection of body of wall masonry, body of wall and floor intersection.

Fig. 2 schematic diagram that to be the carbon fiber pin be connected with the carbon fiber strap with masonry.
Fig. 3 is carbon fiber dowel ends and masonry and the bonding schematic diagram of carbon fiber strap.
Reference numeral: 1-carbon fiber strap; The 2-masonry; The nail bar of 3-carbon fiber pin; 4-end silver.
The specific embodiment
Below in conjunction with accompanying drawing to the utility model to specifying:
As shown in Figure 1 and Figure 2, a kind of carbon fiber pin that is used to ensure carbon cloth and masonry structure collaborative work, by carbon cloth roll coil of strip system form the nail shaft-like, it is characterized in that: the nail bar 3 of described carbon fiber pin penetrates masonry 2, two ends are exposed at the masonry outside, the two ends of nail bar is the strip shape that is cut into, and the carbon fiber strap 1 that end silver 4 is petal expansion, paste above with masonry is pasted fixing.Described end silver 4 generally is three to eight.
The preparation method one of carbon fiber pin: for rolling conveniently, core can be made with a reinforcing bar in the nail bar center of described carbon fiber pin, extracts out after passing masonry again, perhaps also can stay in the masonry.The diameter of carbon fiber pin is less than 12mm.
The preparation method two of carbon fiber pin: be cut into 100mm * 640mm specification with the carbon fiber strap, the diameter of carbon fiber pin (6～8) mm, long is h+400mm, wherein h is a masonry thickness, to follow closely in the middle of the body the long section of h with the dipping bonding adhesive soak into solidify to form strong, carbon fiber pin exposed parts each 200mm of both sides, two ends are tight with the plastics fabric width, prevent that viscose glue from entering.
The stickup of carbon fiber pin: after the carbon fiber pin completes, pasting the masonry surface drilling of carbon fiber strap, the aperture is (12～15) mm, pin is inserted in the hole after having bored the hole, and in the hole, inject epoxy resin structural adhesive, guarantee that pin and masonry bond together.The 200mm long pin plastic sheath that the metope both sides are exposed removes, the carbon fiber dowel ends that exposes is cut into strip shape, be radiation or petal, adopt the HYW-CQ glue on the carbon fiber strap, add a cover the gluing carbon fiber strap of a 250mm * 250mm again, promptly finish the layout of carbon fiber pin.
Described carbon fiber strap can be latticed anyhow two-sided symmetry on the surface of masonry and paste.
Described carbon fiber strap can be the two-sided symmetry of oblique trellis on the surface of masonry and paste.
Described carbon fiber strap also can be the two-sided symmetry stickup of grid+diagonal angle oblique line mixing shape grid anyhow on the surface of masonry.
Described carbon fiber strap is to paste on the masonry two sides, and the carbon fiber pin is single or double drawknot.
Described carbon fiber strap sticks on the metope equal intervals and evenly arranges, the cloth bandwidth is less than 100mm, and the maximum net spacing is not more than 10 skin masonry height, also is not more than 600mm.The overlap joint of carbon fiber strap is long should not establish one the carbon fiber pin less than 200mm in the middle of overlap joint.
