Description

Technical Field

[0001] This utility model relates to a welding support pier, used in the fabrication of steel plate concrete structures during the construction of the nuclear island of a nuclear power plant. Background Technology

[0002] During the construction of the nuclear island of a nuclear power plant, a large number of steel plate concrete structures are required. These structures mainly consist of a steel base plate and steel face plates, which are arranged parallel to each other. Each base plate and face plate has several perforations, into which a threaded steel bar is inserted and welded to the base plate and face plate. Studs are also welded to the opposite surfaces of the base plate and face plates. Concrete is then poured into the space between the base plate and face plates, ultimately forming the wall panels of the steel plate concrete structure. These wall panels are used in the construction of the nuclear island; multiple panels are assembled to form a complete wall. Therefore, the flatness of these wall panels is crucial. The requirements for parallelism are very high. If the surface is uneven, misalignment will occur during assembly. Therefore, in the welding and forming of the above-mentioned steel plate concrete structure, it is necessary to ensure the parallelism between the steel base plate and the steel panel. Thus, when welding the steel base plate and the steel panel, it is necessary to support them with piers. Currently, wooden or metal blocks are used to support them. After welding, the piers are knocked out by hammering, which is a complicated operation. In particular, welding the threaded steel bars will cause welding stress shrinkage, which will reduce the distance between the steel base plate and the steel panel, making it even more difficult to knock the piers out. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a welding support block that can better support the steel base plate and steel panel, and is also easy to disassemble.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a welding support pier, including a base, a fixed support plate fixed to the upper end of the base, a first inclined surface provided at the upper end of the fixed support plate, a movable wedge plate provided at the upper end of the fixed support plate, a second inclined surface provided at the lower end of the movable wedge plate that cooperates with the first inclined surface, the upper end surface of the movable wedge plate being configured as a horizontal support surface, the lower end surface of the base being parallel to the horizontal support surface, a through hole provided on the side wall of the base, an operating groove provided on the movable wedge plate, a force-applying groove wall provided on the operating groove corresponding to the through hole, an avoidance connecting hole provided on the fixed support plate connecting the through hole and the force-applying groove wall, and a limiting structure for restricting the sliding of the movable wedge plate being detachably installed between the fixed support plate and the movable wedge plate.

[0005] As a preferred embodiment, the limiting structure includes a limiting pin, and a semi-circular insertion slot is provided between the first inclined surface and the second inclined surface. The two insertion slots cooperate to form an insertion hole, and the limiting pin is inserted into the insertion hole.

[0006] As a preferred embodiment, the limiting pin portion is exposed outside the insertion hole, and the exposed portion of the limiting pin is provided with a pull hole.

[0007] As a preferred embodiment, the operating groove is a groove with a triangular cross-section, and the force-applying groove wall is vertically arranged.

[0008] As a preferred embodiment, both the through hole and the avoidance connecting hole are inclined through holes, and the inclined holes correspond to and are adapted to the inclined groove wall position of the triangular operating groove.

[0009] As a preferred embodiment, the base includes a base plate with two long side plates and two short side plates. The long side plates and short side plates are welded together to form a rectangular frame, and the through hole is provided on one of the short side plates.

[0010] As a preferred embodiment, a locking structure is also provided between the base and the movable wedge plate to lock the movable wedge plate in place.

[0011] As a preferred embodiment, the locking structure includes a locking hook rotatably mounted on the side of the base, and a locking pin that cooperates with the locking hook is also provided on the side wall of the movable wedge plate.

[0012] After adopting the above technical solution, the effect of this utility model is as follows: The welding support pier includes a base, with a fixed support plate fixed to the upper end of the base. The fixed support plate has a first inclined surface at its upper end and a movable wedge plate at its upper end. The movable wedge plate has a second inclined surface that cooperates with the first inclined surface at its lower end. The upper surface of the movable wedge plate is a horizontal support surface. The lower surface of the base is parallel to the horizontal support surface. A through hole is also provided on the side wall of the base. An operating groove is provided on the movable wedge plate, and a force-applying groove wall corresponding to the through hole is provided on the operating groove. An avoidance connecting hole is provided on the fixed support plate to connect the through hole and the force-applying groove wall. The fixed support plate and the movable wedge plate are also detachable. The device is equipped with a limiting structure to restrict the sliding of the movable wedge plate. Therefore, during use, the bases of multiple support blocks are placed on a steel base plate, and then a steel panel is placed on the movable wedge plate of the support block. Threaded steel bars are then inserted between the steel panel and the steel base plate and welded together to connect them as one unit. After welding, the steel panel and the steel base plate will tightly press against the support block. At this point, the limiting structure is removed, and then a push rod is inserted into the operating slot through the through hole and the connecting hole. The push rod will contact the top of the force application slot wall. Then, the push rod is struck. During the striking process, the movable wedge plate will slide along the first inclined surface of the fixed support plate. Since its sliding surface is inclined, the height of the movable wedge block will decrease, thus separating it from the steel panel. This allows for easier disassembly of the support block, making disassembly easier.

[0013] Furthermore, since the limiting structure includes a limiting pin, and a semi-circular insertion slot is provided between the first and second inclined surfaces, the two insertion slots cooperate to form an insertion hole, into which the limiting pin is inserted. The limiting pin is partially exposed outside the insertion hole, and this exposed portion has a pull hole. Therefore, once the limiting pin is inserted into the insertion hole, the movable wedge plate cannot slide, thus limiting its movement. Tools can be hung in the pull hole and pulled out, releasing the limiting effect and allowing the movable wedge plate to slide freely.

[0014] Furthermore, since the operating groove is a triangular groove with a vertical cross-section and the force-applying groove wall is vertically set, when the push rod is inserted through the through hole, its end can be inserted into the triangular operating groove and will directly act on the vertical force-applying groove wall. This allows the striking force to be better transmitted to the force-applying groove wall, and the sliding of the movable wedge plate is more effortless.

[0015] Furthermore, since both the through hole and the avoidance connecting hole are inclined through holes, and the inclined holes correspond to the inclined groove wall of the triangular operating groove, when the push rod is inserted, it only needs to rest on the edge of the through hole. The inclined holes will conveniently guide the push rod, thus making it easier to accurately insert the push rod into the operating groove.

[0016] Furthermore, a locking structure is provided between the base and the movable wedge plate to lock the movable wedge plate in place. The locking structure includes a locking hook rotatably mounted on the side of the base, and a locking pin on the side wall of the movable wedge plate that engages with the locking hook. This locking structure allows for easy and quick placement of the entire support block in a designated position during installation; and facilitates locking the movable wedge plate and base together when not in use. Since multiple support blocks are required during welding, and the movable wedge plate of each support block is precision-machined to match the corresponding fixed support plate with high parallelism and height accuracy, the locking structure ensures a one-to-one correspondence between the originally paired fixed support plates and the movable wedge plates. Locking the movable wedge plate and fixed support plate together during support block installation and when not in use prevents the mixed use of movable wedge plates from multiple support blocks.

[0023] The present invention will be further described in detail below through specific embodiments.

[0024] like Figure 1-4As shown, a welding support pier includes a base 1, a fixed support plate 2 fixed to the upper end of the base 1, a first inclined surface 21 provided at the upper end of the fixed support plate 2, a movable wedge plate 4 provided at the upper end of the fixed support plate 2, a second inclined surface that cooperates with the first inclined surface 21 provided at the lower end of the movable wedge plate 4, the upper end surface of the movable wedge plate 4 being configured as a horizontal support surface 41, the lower end surface of the base 1 being parallel to the horizontal support surface 41, a through hole 5 provided on the side wall of the base 1, an operating groove 6 provided on the movable wedge plate 4, a force-applying groove wall 61 corresponding to the through hole 5 provided on the operating groove 6, an avoidance connecting hole 3 provided on the fixed support plate 2 connecting the through hole 5 and the force-applying groove wall 61, and a limiting structure for restricting the sliding of the movable wedge plate 4 can be detachably installed between the fixed support plate 2 and the movable wedge plate 4.

[0025] In this embodiment, the base 1 includes a base plate 101, on which two long side plates 102 and two short side plates 103 are mounted. The long side plates 102 and short side plates 103 are welded together to form a rectangular frame. The through hole 5 is provided on one of the short side plates 103. A locking structure is also provided between the base 1 and the movable wedge plate 4 to lock the movable wedge plate 4. The locking structure includes a locking hook 9 rotatably mounted on the side of the base 1, and a locking pin 10 that cooperates with the locking hook 9 is also provided on the side wall of the movable wedge plate 4.

[0026] In this embodiment, the limiting structure includes a limiting pin 7. A semi-circular insertion slot is also provided between the first inclined surface 21 and the second inclined surface. The two insertion slots cooperate to form an insertion hole 11, and the limiting pin 7 is inserted into the insertion hole 11. A portion of the limiting pin 7 is exposed outside the insertion hole 11, and the exposed portion of the limiting pin 7 is provided with a pull hole 8. When the limiting pin 7 is inserted into the insertion hole 11, the movable wedge plate 4 cannot slide, thus limiting the movement of the movable wedge plate 4. Figure 3 As shown, the operating groove 6 is a groove with a triangular cross-section, and the force-applying groove wall 61 is vertically arranged. The through hole 5 and the avoidance connecting hole 3 are both inclined through holes, and the inclined holes are matched with the inclined groove wall 62 of the triangular operating groove 6.

[0027] In use, the base 1 of multiple support blocks is placed on the steel base plate 13, and then the steel panel 12 is placed on the movable wedge plate 4 of the support block. Threaded steel bars 14 are then inserted between the steel panel 12 and the steel base plate 13 and welded together, connecting the steel panel 12 and the steel base plate 13 into one unit. After welding, the steel panel 12 and the steel base plate 13 will tightly press against the support block. At this point, the locking structure is opened, and the limiting pin 7 of the limiting structure can be removed through the pull hole 8 to release the limiting of the movable wedge plate 4. Then, the push rod is used... The push rod 15 passes through the through hole 5, through the avoidance and connecting hole 3, and is inserted into the operating slot 6. The push rod 15 will contact the vertical force application slot wall 61, and the inclined hole will guide the push rod 15. At this time, the push rod 15 is struck. During the striking process, the movable wedge plate 4 will slide along the first inclined surface 21 of the fixed support plate 2. Since its sliding surface is inclined, the height of the movable wedge block will be reduced, thereby separating it from the steel panel 12 above. This allows for better disassembly of the support pier and greatly reduces the difficulty of disassembly.

[0028] When not in use, the locking hook 9 and locking pin 10 of the locking structure cooperate to lock the movable wedge plate 4 and the corresponding base 1 together, avoiding confusion between the movable wedge plates 4 of multiple support blocks, and making it convenient to use.

[0029] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and alterations to the technical solution of the present utility model without departing from its design spirit shall fall within the protection scope defined by the claims of the present utility model.
