Description
Technical field
The present invention relates to a kind of fixing means of concrete component; The invention still further relates to a kind of special fastener of fixing means of concrete component.
Background technology
The mould that agrees with expection concrete component profile is at first made in the method processing that concrete component adopts mould to build more, is equipped with an amount of reinforcing bar in the mould, is steel concrete, and is main by having adhesion stress between the two, compatible deformation behind the load-bearing.Because concrete component has utilized reinforcing bar and concrete performance characteristics rational in infrastructurely, it is higher to form intensity, the structure that rigidity is bigger, its durability and fireproof performance are good, and normability is good, and Mechanical Builds is flexible, and globality, ductility are good, reduce own wt, be applicable to characteristics such as earthquake resistant structure, thereby in building structure and other civil engineerings, be used widely.
At present, normally connect between the concrete component, make good penetrability between the concrete component, but when being to use binding material to connect concrete component, usually the intensity of Lian Jieing is difficult to reach the standard of construction, and restricted to construction environment by binding material.
Summary of the invention
It is more fastening that technical problem to be solved by this invention provides a kind of connection, simple to operate, and construction environment is required the fixing means of low concrete component; Technical problem to be solved by this invention is the special fastener that a kind of fixing means of concrete component also is provided.
For solving the problems of the technologies described above, the invention provides a kind of special fastener of fixing means of concrete component, described securing member is shaft-like securing member.
After adopting such structure, fastener constructions is simple, and is easy to processing.
Below for more convenient understanding technology contents of the present invention, abbreviate the special fastener of the fixing means of concrete component as this securing member.
This securing member is a fastening bolt, and the fastening bolt two ends have screw thread respectively, two clamp nuts respectively with fastening bolt two ends threaded engagement; After adopting such structure, fastening bolt is fixing more firm by the two ends clamp nut, and for convenience detach.
The center line of the shaft-like securing member of this securing member is a circular arc line; After adopting such structure, improve the tensile strength of shaft-like securing member, and can the application-specific operation environment.
For solving the problems of the technologies described above, the present invention also provides a kind of fixing means of concrete component, may further comprise the steps:
A) after concrete component is built, be processed with the installing hole that at least one agrees with securing member in each concrete component, installing hole runs through two sides of concrete component;
B) some concrete component butt joints, the installing hole of concrete component is corresponding on the position, forms an installation passage that is enough to securing member is passed through, and at least one securing member passes described installation passage respectively successively, make concrete component fix, form concrete segment.
After adopting such method, securing member passes some concrete components, utilizes the toughness of the material of securing member own to connect concrete component, make between the concrete component fixing more tight, reinforcement globality and safety.
Below for more convenient understanding technology contents of the present invention, abbreviate the fixing means of concrete component as this method.
The securing member two ends are in the concrete segment outside respectively in the step b) of this method, and the securing member two ends are fixedly connected with banking stop, and the banking stop area is greater than the area of installing hole opening part.
After adopting such method, the banking stop area is greater than the area of installing hole opening part, and banking stop can not enter in the installing hole, when making concrete segment fixedly, banking stop is in the outside of concrete segment, utilizes securing member to cooperate with its two ends banking stop respectively, and the fixing concrete assembly is more firm.
The center line of the installing hole of this method is a circular arc line; After adopting such method, can shorten the length of securing member, more flexible when making the connection concrete component, reduce difficulty of construction.
Be embedded with spiral bar and U type muscle in the concrete component of this method, the installing hole in the step a) is in the spiral bar, and U type muscle is spiral bar fixedly.
After adopting such method, pre-buried spiral bar can play the effect of about beam core inner concrete in the concrete component, when installing hole need bear bigger pressure, to improve the bearing capacity of installing hole, improve the fragility of concrete component, U type muscle plays the fixedly effect of spiral bar.

The specific embodiment
As shown in Figure 1, the special fastener of the fixing means of concrete component comprises zinc-base the fall fastening bolt 5 and the clamp nut 6 of chromate coating preservative treatment;
Fastening bolt 5 is a double threaded screw, and the center line of fastening bolt 5 is a circular arc line, and its radius of central line is 0.465m;
Two clamp nuts 6 respectively with fastening bolt 5 two ends threaded engagement.
When the first concrete component 1a builds shown in Fig. 2 to 4, in the casting die with concrete spouting to the first concrete component 1a, the end face of casting die has first projection, be fixed with the first installing hole sleeve pipe 2a in the casting die, spiral bar 8 and U type muscle 9, the diameter of the first installing hole sleeve pipe 2a is greater than the diameter of fastening bolt 5, the center line radian of the first installing hole sleeve pipe 2a agrees with the center line radian of fastening bolt 5, the first installing hole sleeve pipe 2a, one end stretches out outside the sidewall of casting die, the other end stretches out the first projection outside of the first concrete component 1a, spiral bar 8 is socketed in outside the first installing hole sleeve pipe 2a, and by the fixing spiral bar 8 of U type muscle 9, after the first concrete component 1a moulding, the corresponding position of first projection forms the first notch 3a, and 1/2nd of the length of fastening bolt 5 is in length in the first concrete component 1a greater than the first installing hole sleeve pipe 2a.
In like manner build the second concrete component 1b, when the second concrete component 1b builds, in the casting die with concrete spouting to the second concrete component 1b, the end face of casting die has second projection, be fixed with the second installing hole sleeve pipe 2b in the casting die, spiral bar 8 and U type muscle 9, the diameter of the second installing hole sleeve pipe 2b equals the diameter of the first installing hole sleeve pipe 2a, the center line radian of the second installing hole sleeve pipe 2b agrees with the center line radian of fastening bolt 5, the second installing hole sleeve pipe 2b, one end stretches out outside the sidewall of casting die, the other end stretches out the second projection outside of casting die, spiral bar 8 is socketed in outside the second installing hole sleeve pipe 2b, and by the fixing spiral bar 8 of U type muscle 9, after the second concrete component 1b moulding, the corresponding position of second projection forms the second notch 3b, 1/2nd of the length of fastening bolt 5 is in length in the second concrete component 1b greater than the second installing hole sleeve pipe 2b, and the second concrete component 1b is identical with the structure of the first concrete component 1a.
