Abstract
A square flange plate with an inner arc comprises a rectangular steel plate, wherein a concave arc surface is arranged on one long edge of the steel plate; because it adopts square steel plate as the flange to set up shallower indent cambered surface on the flange and come with the steel pipe external diameter looks adaptation that connects, with form the jack via hole on the steel pipe that connects, when demolising foundation ditch crown beam like this, the movable end of jack can contact the crown beam face, thereby can form outside atress and make the support produce lateral displacement, consequently the utility model discloses be used in assembled concrete pipe support joint specially, solved the condition that the movable end that circular flange can't supply the jack and contact the crown beam face.
Description
Technical Field
The utility model relates to a steel sheet in the aspect of building.
Background
As we know, the assembled concrete pipe support is a prefabricated component, and in order to guarantee batch production, the section size of the assembled concrete pipe support is relatively fixed and uniform, so that the connection adaptability between the assembled concrete pipe support and the crown beam under different working conditions (in different foundation pit environments, the design size of the crown beam is different) is poor.
The concrete pipe support is made of a recyclable material and needs to be disassembled after the construction of the main body structure is completed; because the foundation ditch can produce the strain because of external force in the work progress, so the crown beam can have certain stress to the concrete pipe support in the dismantlement process, so need the jack to carry out the power of unloading earlier, and concrete pipe supports the tip and be closed cylindrical, and the direct connection with the crown beam can make the jack have no stress point. Moreover, the traditional fabricated supports (steel supports) can only bear pressure but not tensile force in the use process of the foundation pit, and the upper-layer support is easy to lose effectiveness when the upper and lower stresses of the foundation pit are uneven.
To this end, the applicant has specifically developed a joint suitable for a fabricated concrete pipe support, which includes a steel pipe, a crown beam coupling flange plate coupled to one end of the steel pipe, and a flange group coupled to the other end of the steel pipe. However, the flange plates seen at present are all circular, and if the flange plates are used as the crown beam connecting flange plates, when the foundation pit crown beam is dismantled, the movable end of the jack cannot contact the crown beam surface, so that external stress cannot be formed to enable the support to generate transverse displacement. Therefore, the current circular ring-shaped flange plate cannot use the joint to the fabricated concrete pipe support, and for this reason, the applicant has developed a square flange specially applied to the fabricated concrete pipe support joint.
Disclosure of Invention
An object of the utility model is to overcome prior art not enough, provide a square flange with inner arc, it is used in assembled concrete pipe support joint specially.
In order to solve the technical problem, the utility model adopts the following technical scheme:
a square flange plate with an inner arc is used on a joint supported by an assembly type concrete pipe and comprises a rectangular steel plate, wherein a concave arc surface is arranged on one long edge of the steel plate, the radius of the concave arc surface is matched with the outer diameter of a steel pipe of the joint, but the arc depth is far smaller than the radius of the steel pipe; and at least two bolt holes are formed in the steel plate.
In the improved scheme of the square flange plate with the inner arc, the bolt holes are cross holes.
Compared with the prior art, the beneficial effects of the utility model are that: owing to adopt square steel sheet as the flange to set up shallower indent cambered surface on the flange and come with the steel pipe external diameter looks adaptation that connects, with form the jack via hole on the steel pipe that connects, when demolising the foundation ditch crown beam like this, the movable end of jack can contact the crown beam face, thereby can form outside atress and make the support produce lateral displacement, consequently the utility model discloses be used in assembled concrete pipe support joint specially, solved the condition that the movable end that circular flange can't supply the jack and contact the crown beam face.
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
[ description of the drawings ]
FIG. 1 is a perspective view of the present embodiment;
fig. 2 is a view showing a state in which the present embodiment is applied to a joint of a fabricated concrete pipe support.
[ detailed description ] embodiments
The utility model relates to a square flange board with inner arc, as shown in figure 1, be used in the joint that assembled concrete pipe supported, it includes rectangular steel sheet 1, is equipped with the cambered surface 11 of indent on a long limit of this steel sheet 1, its radius with the 21 external diameters looks adaptations of steel pipe of joint 2, but its arc is far less than the external diameter of this steel pipe (usually with the arc deeply account for 1/6 to 1/3 of steel pipe outer wall diameter suitable), in this embodiment, the external diameter of steel pipe is 400mm, the length 600 mm of upper and lower flange board 2, 3 of crown beam, wide 190mm, the arc is deep 95 mm; at least two bolt holes 12 are provided in the steel plate 1. When the lifting jack is used, two square flanges are needed to be welded on the joint, as shown in fig. 2, so that the two square flanges are oppositely clamped on the outer wall of the steel pipe through the inner cambered surfaces of the two square flanges and are respectively welded with the steel pipe, and a jack through hole A is formed between the two square flanges; in order to support the jack, the steel pipe is provided with a jack supporting plate 22 which is axially placed on the pipe wall opposite to the jack through hole A, when the jack is placed on the jack supporting plate 22 of the joint and the jack is operated, one end of the steel pipe is propped against the surface of the flange at the inner end of the joint, and the other end of the steel pipe is propped against the end face of the crown beam after penetrating through the jack through hole, so that external stress can be formed, and the support can generate transverse displacement.
From the above, the utility model discloses a square steel plate is as the flange to set up more shallow indent cambered surface on the flange and come with the steel pipe external diameter looks adaptation that connects, with form the jack via hole on the steel pipe that connects, when demolising foundation ditch crown beam like this, the activity end of jack can contact the crown beam face, thereby can form outside atress messenger and support and produce lateral displacement, consequently the utility model discloses be used in assembled concrete pipe support joint specially, solved the condition that the movable end that circular flange can't supply the jack and contact the crown beam face.
Preferably, the bolt holes 12 are cross holes to facilitate installation and adjustment of the bolts therethrough.
Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims. Therefore, the detailed description of the embodiments of the present disclosure is to be construed as merely illustrative, and not limitative of the present disclosure, but rather to limit the scope thereof by the appended claims.
