Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a pre-embedded structure of a concrete integrally cast seam plate. Background Art

[0002] Fully cast-in-place concrete exterior walls refer to the use of aluminum molds to achieve one-time casting of the exterior walls, avoiding quality problems such as cracks and leakage in the exterior walls, saving construction time and improving efficiency. However, since the fully cast-in-place concrete exterior walls change the stress of the original main structure of the building, the lateral stiffness of the building has increased significantly, which is not conducive to the energy consumption performance of the structure's earthquake resistance. Therefore, the use of seam panels to separate the cast-in-place non-load-bearing walls and shear walls can effectively solve the adverse effects of the fully cast-in-place structure on the main structure. Seam panels are a material used to set structural seams in concrete structures. They are usually found in the seams made between non-load-bearing walls and load-bearing beams, columns and walls to reduce the impact of factors such as earthquakes on the wall and prevent cracking. The seam panel technology has been widely praised by the industry in recent years. The most widely used ones are PVC-U finished seam panels, which are easy to install and low in cost.

[0003] In order to make the connection between the seam plate and the steel bar more convenient, the prior art adopts a buckle to connect the steel bar. For example, Chinese patent CN220538912U discloses a buckle-type fixed seam plate. When the structural steel bars of the shear wall are installed, the buckle-type fixed seam plate is positioned at a preset position, and the fixed steel bar is inserted into the reserved hole and the staggered position of the buckle according to the preset required length. After the insertion is completed, the fixed steel bar is pressed into the buckle arc from the missing corner of the buckle arc and fixed, and the position of the main body of the seam plate is adjusted until it is positioned at the preset position, and the fixed steel bar and the structural steel bar are tied as a whole to achieve the installation and fixation of the buckle-type seam plate.

[0004] Although the above technology can fix the steel bars and the seam plates by means of clips, due to the different ratios of the spacing between the steel bars on both sides and the spacing between the waist holes on both sides during installation, it is easy for the steel bars on one side to be inserted into the clip while the other side cannot be inserted, resulting in an unstable installation and the seam plates tilting or falling when pouring concrete. Summary of the invention

[0005] In order to solve the problem proposed in the above background technology that the ratio of the spacing between the steel bars on both sides during installation is different from the spacing ratio of the waist holes on both sides, which makes it easy for the steel bars on one side to be inserted into the buckle while the other side cannot be inserted, resulting in insufficient stability in the installation and the seam plate tilting or falling when pouring concrete, the utility model adopts the following technical solution.

[0007] Preferably, the abutment plate is slidably connected to the inside of the sliding plate, and a return spring is provided between the abutment plate and the sliding plate. After the abutment plate contacts the fixed steel bar, it moves toward the inside of the sliding plate and compresses the return spring.

[0008] Preferably, a through groove is provided at the upper end of each sliding plate, and when concrete is poured, the through groove fills the interior of the sliding plate to fix the position of the abutment plate and the position of the return spring.

[0009] Preferably, a plurality of notched grooves are provided on the mounting plates on both sides, and the notched grooves can increase the contact area between the concrete and the mounting plates when pouring concrete.

[0010] Preferably, the fixing mechanism includes a threaded rod and a hexagonal head, and one end of the first cavity on both sides is rotatably connected to a threaded rod inserted into the second cavity, and the outer wall of the opposite end of each threaded rod is fixedly connected to a hexagonal head. Each threaded rod is threadedly connected to the mounting plates on both sides respectively, and the threaded rod is rotated by rotating the hexagonal head, thereby controlling the mounting plates on both sides to move separately.

[0011] Preferably, the other ends of the first cavities on both sides are also provided with threaded rods and hexagonal heads, and a linkage mechanism is installed between the threaded rods on both sides in the vertical direction, so that the threaded rods on both sides in the vertical direction rotate simultaneously.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The threaded rod is rotated by rotating the hexagonal head in the driving mechanism, and the pulley and the linkage belt in the linkage mechanism are used to rotate the vertical threaded rods on both sides at the same time, so that the mounting plate pushes each sliding plate and the abutment plate to move toward the fixed steel bar until they are in contact. The abutment plate can be ensured to always contact the outside of the fixed steel bar by adjusting it separately.

[0015] 2. By setting a reset spring, the abutment plate moves toward the inside of the sliding plate after contacting the fixed steel bar and compresses the reset spring, so that the fixed steel bars in the same vertical position can be abutted by the abutment plate.

[0016] 3. By setting the notch groove and the through groove, the contact area between the concrete and the seam plate body, the sliding plate and the mounting plate can be increased after pouring the concrete, so that the fixing effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0028] like Figure 1 As shown, it is a schematic diagram of a pre-embedded structure of a concrete integrally cast seam plate according to a preferred embodiment of the utility model. The pre-embedded structure of the concrete integrally cast seam plate in this embodiment comprises a seam plate body 100 with a protrusion 101 arranged on the outside, and a plurality of waist holes 105 are vertically arranged on both sides of the seam plate body 100. A fixed steel bar 102 passes through the interior of each waist hole 105. In this embodiment, the seam plate body 100 can be fixed by plugging the waist hole 105 with the fixed steel bar 102.

[0029] like Figure 2 As shown, it is a schematic diagram of the structure of the seam plate body in this embodiment; a first cavity 103 is provided at the center of the upper end of the seam plate body 100, and second cavities 104 are provided on both sides of the first cavity 103, and each waist hole 105 is respectively connected to the interior of the second cavity 104 on both sides. In this embodiment, the first cavity 103 and the second cavity 104 can be used to fix the fixed steel bar 102 and the seam plate body 100 when pouring concrete, and the concrete can fill the interior of the first cavity 103 and the second cavity 104, so that the connection strength can be higher after the concrete is poured.

[0030] like Figure 2 as well as Figure 3 As shown, it is the seam plate body and Figure 2The enlarged structural schematic diagram at point A in the middle shows that sliding grooves 106 with the same number and position as the waist holes 105 and connected to the second cavities 104 on both sides are arranged on both sides of the interior of the first cavity 103, and a sliding plate 201 is slidably connected to the interior of each sliding groove 106, and an abutment plate 202 is connected to the end of each sliding plate 201 close to the second cavity 104, and a plurality of sliding plates 201 on each side are fixedly connected to a mounting plate 200 at one end close to the interior of the first cavity 103. In this embodiment, the mounting plates 200 on both sides are simultaneously moved toward the second cavities 104 on both sides, so that each abutment plate 202 can contact the outer wall of the fixed steel bar 102, and the seam plate body 100 can be fixed to the fixed steel bar 102 by the thrust from the inside to both sides.

[0031] like Figure 4 as well as Figure 5 As shown, it is a schematic diagram of the threaded rod and return spring as well as the linkage belt and notch groove structure in this embodiment. The upper and lower ends of the first cavities 103 on both sides are rotatably connected with threaded rods 204 inserted into the second cavity 104, and the outer wall of the opposite end of each threaded rod 204 is fixedly connected with a hexagonal head 205, and each threaded rod 204 on the same vertical side is threadedly connected to the mounting plates 200 on both sides respectively, and one end of each threaded rod 204 away from the hexagonal head 205 is detachably connected with a pulley 207, and every two opposite pulleys 207 are rotatably connected, and a linkage belt 208 is sleeved on the outer wall of every two vertical pulleys 207. In this embodiment, rotating the hexagonal head 205 causes the threaded rod 204 to rotate, and the cooperation of the pulley 207 and the linkage belt 208 causes the vertical threaded rods 204 on both sides to rotate at the same time, so that the mounting plate 200 pushes each sliding plate 201 and the abutment plate 202 to move toward the fixed steel bar 102 until they contact the outer wall of the fixed steel bar 102, thereby fixing the seam plate body 100.

[0032] It is worth noting that the above-mentioned threaded rod 204 and hexagonal head 205 are the fixing mechanisms in this embodiment, and the fixing mechanisms include but are not limited to the threaded rod 204 and the hexagonal head 205.
