Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In view of the above purpose, in a first aspect of the embodiments of the present invention, an embodiment of a C-shaped steel double-split connector for an earthquake-resistant bracket is provided. Fig. 2 shows a schematic view of a C-shaped steel double-split connecting piece of the anti-seismic bracket provided by the invention.
The utility model provides a antidetonation support C shaped steel double pin connector, is including the connecting piece bottom plate 204 and the fastener that contain the boss, and this fastener is through passing the boss of C shaped steel back hole 206 and connecting two C shaped steel 205 of placing back to back. As shown in FIG. 2, the C-shaped steel back hole 206 is a through hole with two sides each being a semicircle and a middle being a rectangle. The connected structure is shown in fig. 3.
In a preferred embodiment, the boss is a circular boss 203.
In a preferred embodiment, a threaded hole 201 is contained within the circular boss 203.
In a preferred embodiment, there are 2 circular bosses 203 and located at each end of the connector base plate 204.
In a preferred embodiment, the fasteners are high strength bolts 207 with flanged edges 202. It is known that high-strength bolts are bolts made of high-strength materials, have performance levels of 8.8 or more, and are widely used for connecting equipment such as bridges, rails, high-pressure equipment and the like.
In a preferred embodiment, high strength bolts 207 mate with threaded holes 201 of circular boss 203. That is, the high-strength bolt 207 and the screw hole 201 of the circular boss 203 can be used in cooperation with each other.
In a preferred embodiment, the threaded holes 201 of the circular bosses 203 mate with the C-section steel back holes 206. That is to say, the threaded hole 201 of the circular boss 203 is adapted to the C-shaped steel back hole 206, and too large results in the high-strength bolt not passing through, and too small does not play a role.
In a preferred embodiment, the circular bosses 203 are equidistant from the center of the C-section steel back hole 206. Wherein, the distance between the centers of the circular bosses 203 is the distance between the centers of the threaded holes in the two circular bosses 203 on the connecting piece base plate 204. The center-to-center distance of the C-shaped steel back holes 206 is the distance between the centers of two adjacent semicircles of two adjacent C-shaped steel back holes 206. The distance between the centers of the circular bosses 203 is equal to the distance between the centers of the C-shaped steel back holes 206, so that smooth connection can be ensured.
In a preferred embodiment, the height of the boss is less than the sum of the thicknesses of the two C-section steels 205 to be joined. If the height of the boss is greater than the sum of the thicknesses of the two C-shaped steels 205 to be connected, when the high-strength bolt 207 is screwed into the threaded hole 201, the flange edge cannot clamp the C-shaped steel 205, and then the connecting piece base plate cannot clamp the C-shaped steel 205, so that double-assembly of the two C-shaped steels 205 fails.
The invention also provides a method for installing the C-shaped steel double-spliced connecting piece of the anti-seismic support, which comprises the following steps:
1) aligning two C-shaped steels 205 to be connected back to back;
2) placing connector base plate 204 in position with the bosses penetrating back holes 206 of C-section steel 205;
3) screwing a high-strength bolt 207 with a flange edge into the threaded hole 201 of the boss and locking;
4) the double assembly is achieved by clamping two C-section steels 205 together by clamping the flange 202 and the connector base plate 204 together.
It should be noted that, the steps of the above-mentioned embodiments of the method for installing the double-split C-section steel of the anti-seismic support can be mutually intersected, replaced, added and deleted, so that the reasonable combination and permutation of the method for installing the double-split C-section steel of the anti-seismic support also belong to the protection scope of the invention, and the protection scope of the invention should not be limited to the above-mentioned embodiments.
It can be seen from the above embodiments that the double-spliced C-shaped steel connecting piece for the anti-seismic support and the installation method thereof provided by the embodiments of the invention can realize mechanical locking of C-shaped steel on an engineering site through a mechanical connection mode so that the C-shaped steel can be assembled into double-spliced C-shaped steel to be suitable for various purposes, and the process does not need welding, saves installation time, has stable performance, high safety coefficient and is convenient to connect.
The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
