The utility model discloses the technical problem that will solve lies in: the utility model provides an underground continuous wall pre-buried I-steel connects, it has solved present pre-buried I-steel joint structure too simple, can appear joint strength not enough, and the prevention of seepage effect is not good to and the problem of concrete streaming.
The utility model discloses the technical problem that will solve takes following technical scheme to realize:
the utility model provides an embedded I-steel of underground continuous wall connects, it includes pterygoid lamina, web, and the pterygoid lamina middle part of two parallels is connected through perpendicular welded web, and pterygoid lamina and web constitute the I-steel, still includes water-stop sheet, peg, locating plate, the welding of web middle part both sides logical length has the water-stop sheet, and the web both sides between water-stop sheet and pterygoid lamina are equipped with the multichannel peg perpendicularly, and the welding of every pterygoid lamina outside middle part logical length has a locating plate.
As a preferred example, the bottom of the positioning plate is cut into an oblique angle.
As a preferred example, the height of the stud projecting web is smaller than the height of the water-stop sheet projecting web.
As a preferred example, the water-stop sheet, the positioning sheet and the wing plate are equal in length.
The utility model has the advantages that:
(1) the embedded I-shaped steel joint has improved performances, but has simple process, low cost and convenient installation;
(2) the studs anchored on the web plate are beneficial to enhancing the connection strength of the embedded joint and the concrete wall body constructed in the later period;
(3) the waterproof plate welded in the middle of the web plate increases an underground water seepage path, external seepage water flows down along the waterproof plate and cannot enter the inner side of the joint of the continuous wall, the anti-seepage effect of the embedded joint is improved, meanwhile, in the process of lowering the reinforcement cage, the waterproof plate is higher than the stud, the guiding and protecting effects are achieved, and damage to the stud caused by direct collision of the reinforcement cage with the stud when the reinforcement cage is lowered is avoided;
(4) the positioning plates with equal length are welded on the outer sides of wing plates of the I-shaped steel, when the I-shaped steel connectors are embedded, the positioning plates are embedded into the groove walls, the I-shaped steel and the groove walls are fixed, in addition, the positioning plates on the two sides are cut into the groove walls, and when concrete is poured into the groove on one side, the concrete can be prevented from flowing around to the other side, not poured, of the embedded connectors from one side.
Drawings
Fig. 1 is a schematic top view of the present invention;
FIG. 2 is a schematic structural view of one side of the positioning plate of the present invention;
FIG. 3 is a schematic view of the waterproof board and one side of the stud according to the present invention;
fig. 4 is the structure diagram of the present invention installed in the diaphragm wall.
In the figure: the device comprises a wing plate 1, a web plate 2, a water stop plate 3, a stud 4, a positioning plate 5 and an oblique angle 51.
Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.
As shown in fig. 1-4, the embedded I-steel joint for the underground diaphragm wall comprises wing plates 1 and webs 2, wherein the middles of the two parallel wing plates 1 are connected through the webs 2 which are vertically welded, the wing plates 1 and the webs 2 form I-steel, the embedded I-steel joint further comprises water-stop plates 3, studs 4 and positioning plates 5, the water-stop plates 3 are welded on two sides of the middle of the webs 2 in a long-running mode, a plurality of studs 4 are vertically arranged on two sides of the webs 2 between the water-stop plates 3 and the wing plates 1, and one positioning plate 5 is welded on the middle of the outer side of each wing plate 1 in.
Examples
The bottom of the positioning plate 5 is cut into an oblique angle 51. Reduce the resistance with the cell wall, be convenient for insert in the groove section.
The height of the studs 4 protruding the web 2 is less than the height of the water-stop sheet 3 protruding the web 2. Avoid direct collision with the peg 4 when steel reinforcement cage transfers, cause the damage to peg 4.
In the partitions formed by the water-stop sheet 3 and the wing plate 1, two studs 4 are arranged on the web 2 in each partition, and the distance between every two adjacent studs 4 is 150 mm.
