Description
Technical field
The utility model relates to a kind of bar planting structure, is specifically related to a kind of can employing and the reinforcing bar of a kind of larger equivalent diameter of muscle acquisition, solves the bar planting problem of the newly-increased component of larger quantity of reinforcement.
Background technology
Along with the transformation demand of existing reinforced concrete structure gets more and more, the appearance of newly-increased large-span reinforced concrete member, the arrangement of reinforcement of newly-increased component is also more increasing.
Embedding re-bar technique is usually used in the Bar Anchorage that existing reinforced concrete structure increases component newly, generally for meeting the tensile strength of post-installing rebar, bar planting is had to the requirement of spacing, General Requirements spacing 5d, more than back gauge 2.5d.Because newly-increased member section size is subject to the restriction of existing structure, causing some large-span to increase newly, the arrangement of reinforcement of component is intensive causes bar planting difficulty.
For solving the intensive bar planting design that causes of newly-increased reinforced component and constructional difficulties, proposing the steel bar stress that newly-increased component implants and adopting and the arrangement of muscle.
Utility model content
For the problems referred to above, main purpose of the present utility model is the method for the reinforcing bar providing the larger equivalent diameter of a kind of acquisition, solves the bar planting problem of the newly-increased component of larger quantity of reinforcement.
The utility model solves above-mentioned technical problem by following technical proposals: a kind ofly adopt and the bar planting structure of muscle, described bar planting structure comprise and muscle group and around and the stirrup of muscle group, and muscle group comprises some groups, stirrup comprises some, stirrup around and muscle group, build into concrete in the reinforcing cage that also muscle group and ring muscle form, form a concrete reinforcement beam, concrete reinforcement beam implants the infall of reinforced concrete post and reinforced concrete beam, each group also muscle group comprises 2 or 3 reinforcing bars, 2 or 3 reinforcing bars also become a branch of, adjacent and the distance of muscle group is not less than the equivalent diameter of 5 times and muscle group, and the outermost distance of muscle group distance concrete reinforcement post is not less than the equivalent diameter of 2.5 times and muscle group.
In preferred embodiment of the present utility model: and two ends of two reinforcing bars in muscle group are welded together, the length of welding is not less than and 10 times of muscle diameter.
Positive progressive effect of the present utility model is: the utility model solves the intensive bar planting design that causes of arrangement of reinforcement and constructional difficulties, adopts and muscle obtains a kind of reinforcing bar of larger equivalent diameter, under the prerequisite meeting bar planting spacing, meets the requirement of bearing capacity.Adopt and the embedding re-bar technique of muscle, can be placed on first row by more reinforcing bar, the effective stressed height increasing reinforced concrete member cross section decreases actual quantity of reinforcement.And the intensity of muscle bar planting is controlled by the implantation length of reinforcing bar, the intensity of adhesive.And the bar planting intensity of muscle draws by calculation and test.The utility model is specially adapted to the implantation problem of the reinforcing bar of newly-increased large-span reinforced concrete member on existing reinforced concrete structure.
Accompanying drawing explanation
Fig. 1 adopts in the utility model and one of structural representation of the bar planting form of muscle.
Fig. 2 adopts in the utility model and the structural representation two of the bar planting form of muscle.
Detailed description of the invention
The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 adopts in the utility model and one of structural representation of the bar planting form of muscle, Fig. 2 adopts in the utility model and the structural representation two of the bar planting form of muscle, as shown in Figure 1-2: the structure in the utility model comprise and muscle group 1 and around and the stirrup 2 of muscle group 1, and muscle group 1 comprises some groups, stirrup 2 comprises some, stirrup 2 around and muscle group 1, build into concrete in the reinforcing cage that also muscle group 1 and ring muscle 2 form, form a concrete reinforcement beam 3, concrete reinforcement beam 3 implants the reinforced concrete post 4 of existing structure and the infall of reinforced concrete beam 5, each group also muscle group 1 comprises 2 reinforcing bars, 2 reinforcing bars also become a branch of, adjacent and the distance of muscle group is not less than the equivalent diameter of 5 times and muscle group, and the outermost distance of distance concrete reinforcement post of muscle group is not less than the equivalent diameter of 2.5 times and muscle group.
Wherein, and the equivalent diameter value of muscle group is as follows: two and the desirable 1.41 times of single steel bar diameters of muscle equivalent diameter; Three and the desirable 1.73 times of single steel bar diameters of muscle equivalent diameter.
In concrete implementation process of the present utility model, and two ends of two reinforcing bars in muscle group 1 are welded together, the length of welding is not less than and 10 times of muscle diameter, adopt above value on the one hand can by and two reinforcement welding in muscle group 1 together, obtaining an equivalent diameter is the reinforcing bar of de.Diameter be the reinforcing bar of de without the need to other purchase, in fact, the bar diameter that market is supplied usually is less than de.
Two and muscle can arrange by the mode of vertical and horizontal; Three and muscle press isosceles triangle layout, and the center of gravity of muscle is the center of gravity of equivalent reinforcing bar.Namely S1 >=the 5*de in Fig. 1 and 2, S2 >=2.5*de.Adopt and solve the intensive bar planting design that causes of arrangement of reinforcement and constructional difficulties with upper type, both met bar planting pitch requirements, and also met the demand of intensity, and without the need to purchasing the reinforcing bar of other diameter.
The utility model adopts and the bar planting structure of muscle, solves the intensive bar planting design that causes of arrangement of reinforcement and constructional difficulties, adopts and muscle obtains a kind of reinforcing bar of larger equivalent diameter, under the prerequisite meeting bar planting spacing, meets the requirement of bearing capacity.Adopt and the embedding re-bar technique of muscle, can be placed on first row by more reinforcing bar, the effective stressed height increasing reinforced concrete member cross section reduces actual arrangement of reinforcement quantity.And the intensity of muscle bar planting is controlled by the implantation length of reinforcing bar, the intensity of adhesive.And the bar planting intensity of muscle draws by test.And two ends of two reinforcing bars in muscle group are welded together, the length of welding is not less than and 10 times of muscle diameter, the convenient and construction of muscle.
The utility model is specially adapted to the implantation problem of the reinforcing bar of newly-increased large-span reinforced concrete member on existing reinforced concrete structure.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
