The implementation, functional features and advantages of the objects of the present invention will be further explained with reference to the accompanying drawings.
Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The present invention will be described in detail with reference to the following examples.
Referring to fig. 1, which is a schematic view of an overall structure of a wall connecting member according to an embodiment of the present invention, a steel pipe 3; the threaded connecting rod 2 is welded in the middle of the steel pipe 3, and the threaded connecting rod 2 is perpendicular to the steel pipe 3; a rectangular steel plate 1, wherein one long side of the rectangular steel plate 1 is welded to one end of the steel pipe 3, and one short side of the rectangular steel plate 1 is welded to one end of the threaded connecting rod 2; and a nut 6 matched with the other end of the threaded connecting rod 2; wherein the length of the short side of the rectangular steel plate 1 is defined as L1, the thickness of the shear wall 7 is defined as L2, and the length L of the threaded connecting rod 2 satisfies the following conditions: l > L1+ L2; the other end of the threaded connecting rod 2 can penetrate through a connecting through hole reserved in the shear wall body 7 and is in threaded fit with the nut 6 on the other side of the shear wall body 7.
The wall connecting piece further comprises a fastener 4 sleeved at the other end of the steel pipe, and the wall connecting piece is connected with an outer scaffold 7 through the fastener 4.
The length of the steel pipe 3 is defined as L3, and the long side of the rectangular steel plate 1 is defined as L4, wherein L3 is about 30 cm-50 cm. In this embodiment, L3 is approximately 35 cm. On one hand, in order to enable the fastener 4 to be conveniently and stably installed on the top of the steel pipe 3 and enable the external scaffold 7 to generate small acting force on the threaded connecting rod 2, a large installation space needs to be reserved on the top of the steel pipe 3; on the other hand, in order to increase the welding area between the rectangular steel plate and the steel pipe as much as possible, it is necessary to reduce the reserved space and increase the contact area between the steel pipe and the rectangular steel plate. Therefore, it is preferable that the length of the steel pipe is L3 and the length of the long side L4 of the rectangular steel plate satisfies: 2/3L3 ≧ L4 ≧ 1/2L 3. In one embodiment, 2/3L3 ═ L4. In addition, the length of the short side of the rectangular steel plate 1 is the distance from the steel pipe 3 to the wall. On the one hand, the increase in the length of the short side of the rectangular steel plate 1 increases the welding area of the rectangular steel plate 1 and the threaded link 2. However, on the other hand, if the length of the short side of the rectangular steel plate 1 is too large, the pressure applied to the end (a) of the rectangular steel plate 1 away from the threaded rod 2 (see fig. 2) is much greater than that applied to other positions, and the greater the length of the short side of the rectangular steel plate 1, the more easily the end a is deformed (at the same thickness). Therefore, the short side of the rectangular steel plate is preferably 5cm to 10 cm. In one embodiment, the short side of the rectangular steel plate is about 8 cm.
And a gasket 5 is also arranged between the nut 6 and the shear wall 7. The gasket is a steel backing plate. The bottom surface of the steel pipe is flush with the bottom surface of the rectangular steel plate. The number of the nuts is two. The threaded connecting rod penetrates through the outer side of the shear wall body, and then is screwed down by sleeving the steel base plate and using the two nuts, so that the connection between the shear wall body and the threaded connecting rod is more stable, and the further loosening of the nuts and potential safety hazards are avoided.
Fig. 2 is a schematic view of a usage status of the recyclable wall connecting member according to an embodiment of the present invention.
A method for using a recyclable wall connecting piece comprises the following steps:
s1, the end of the threaded connecting rod 2 of the wall connecting piece is inserted into a reserved connecting through hole of the shear wall 7 and extends out of the shear wall 7;
s2, the rectangular steel plate 1 is tightly attached to the shear wall 7;
s3, sleeving a steel backing plate 5 on one end, penetrating out of the shear wall 7, of the threaded connecting rod 2, and screwing the threaded connecting rod through a nut 6;
