[0021] Such as Figures 1 to 5As shown in the figure, the present utility model provides an assembly adjustable isolation bearing embedded sleeve positioning mold, and the assembly adjustable isolation bearing embedded sleeve positioning mold includes: an embedded box 1, an adjusting rod 2, and an adjustable embedded sleeve 3. Among them, the embedded box 1 is a box body with an open upper end, and sliding grooves 11 are arranged on two opposite side walls of the box body along the first direction X. The bottom plate of the embedded box 1 is fixedly connected to the corresponding embedded anchor bars 4. The adjusting rod 2 includes a straight rod and sliders fixed at both ends of the straight rod. The sliders at both ends of the straight rod are correspondingly and movably arranged in the two sliding grooves 11. The adjustable embedded sleeve 3 is a pipe fitting with at least one open end. A through hole is arranged at the other end of the adjustable embedded sleeve 3, and the center line of the through hole is perpendicular to the center line of the adjustable embedded sleeve 3. The through hole is movably sleeved on the straight rod of the corresponding adjusting rod 2. The adjustable embedded sleeve 3 is arranged in the embedded box 1 and one end of the adjustable embedded sleeve 3 is not higher than the upper end of the embedded box 1.
[0022] In some examples, the embedded box 1 includes four side plates and a bottom plate. Among them, the side plates are bent in the middle or at the lower part, that is, the upper end and the lower end of the side plates are deflected towards the inside of the embedded box 1. The bottom plate is a horizontal plate member, and the bottom plate is fixedly connected to the four side plates, for example, by welding, to form a box body with an open upper end. The side plates are bent, which can prevent the solidified concrete from falling off the embedded box 1 after the grout is poured later, and can improve the firmness of the joint position.
[0023] The embedded box 1 as a whole can be a cuboid, that is, the lengths of two of the four side plates are greater than the remaining two side plates. The sliding grooves 11 are arranged on the inner side surfaces of the longer side edges. The sliding grooves 11 can be formed by bending the whole side plates or by casting.
[0024] The two ends of the adjusting rod 2 are correspondingly arranged in the sliding grooves 11, that is, the axial direction of the straight rod of the adjusting rod 2 is perpendicular to the first direction X, and the adjusting rod 2 can slide reciprocally along the first direction X. An adjustable embedded sleeve 3 is movably arranged on each adjusting rod 2. The lower end of the adjustable embedded sleeve 3 can be a rod body, and a through hole penetrating the rod body is arranged at the lower end of the adjustable embedded sleeve 3. The extending direction of the center line of the through hole is perpendicular to the first direction X. The straight rod penetrates through the through hole, and the adjustable embedded sleeve 3 can slide reciprocally along the straight rod. It can be understood that the adjustable embedded sleeve 3 can slide along the first direction X and perpendicular to the first direction X in the embedded box 1.
[0025] During the use process, the embedded box 1 can be installed at the corresponding position relatively accurately. Subsequently, the position of the adjustable embedded sleeve 3 in the embedded box 1 can be further finely adjusted, which can simplify the difficulty of adjusting the position of the adjustable embedded sleeve 3, avoid the overall deviation and inclination of the adjustable embedded sleeve 3 caused by external force interference, and can reduce the rework situation.
[0026] In some embodiments, an internal thread is provided at the open end of one end of the adjustable embedded sleeve 3. The assembling and adjustable seismic isolation bearing embedded sleeve positioning die further includes a cover plate 6, which is a plate member adapted to the upper opening of the embedded box 1. A plurality of sleeve holes are provided on the cover plate 6, and the plurality of sleeve holes correspond to the plurality of adjustable embedded sleeves 3 located in the embedded box 1 one by one. A screw is provided at one end of each adjustable embedded sleeve 3, and the screw fixes the cover plate 6 to the seismic isolation bearing embedded sleeve, and the cover plate 6 closes the upper opening of the embedded box 1.
[0027] Exemplarily, 3 to 6 adjustable embedded sleeves 3 can be provided in the embedded box 1, and the plurality of adjustable embedded sleeves 3 are evenly arranged in the embedded box 1. To prevent concrete from entering the embedded box 1 during the pouring of the lower column pier, a cover plate 6 can be provided on the embedded box 1. According to the adjustable embedded sleeves 3 in the embedded box 1, sleeve holes can be provided at corresponding positions on the cover plate 6. The upper opening of each adjustable embedded sleeve 3 is docked with the corresponding sleeve hole. After a screw passes through the sleeve hole and is screwed with the thread of the corresponding adjustable embedded sleeve 3, the cover plate 6 can be fixed to the embedded box 1 to achieve the purpose of closing the embedded box 1. In addition, the cover plate 6 can relatively fix the position of the adjustable embedded sleeve 3, which is convenient for determining the position of the fixed adjustable embedded sleeve 3 in the lower column pier through the position of the screw, and is convenient for on-site personnel to adjust the position of the embedded box 1.
[0028] In some embodiments, a plurality of anchor bar through holes are provided on the bottom plate of the embedded box 1, and a plurality of embedded anchor bars 4 penetrate through the anchor bar through holes one by one. External threads are provided at the ends of the embedded anchor bars 4. A first nut is provided on the embedded anchor bar 4 located below the embedded box 1, and a second nut is provided on the embedded anchor bar 4 located inside the embedded box 1, and the first nut and the second nut clamp the bottom plate of the embedded box 1.
[0029] The embedded anchor bars 4 can be deformed steel bars. The plurality of embedded anchor bars 4 are fixed on the bottom plate and extend into the concrete poured in the lower column pier at the same time, which can improve the stability of the embedded box 1 in the lower column pier. It should be noted that the embedded anchor bars 4 can be fixed to the steel bars in the lower column pier through steel wires.
[0030] In some embodiments, the assembling and adjustable seismic isolation bearing embedded sleeve positioning die further includes a positioning rod 5. The positioning rod 5 is fixed to the upper end of the screw, and the center line of the positioning rod 5 and the center line of the screw are coplanar.
[0031] Exemplarily, a positioning rod 5 can be provided at the upper end of the screw. There is at least one positioning rod 5.

In this way, during on-site installation, the position of the adjustable embedded sleeve 3 can be accurately found through the positioning rod 5.
[0032] In some other examples, there may be two positioning rods 5. The center lines of the two positioning rods 5 are in the same vertical plane and symmetric about the center line of the adjustable embedded sleeve 3. Or there may be four positioning rods 5. The center lines of two of the positioning rods 5 are in the same vertical plane and symmetric about the center line of the adjustable embedded sleeve 3, and the center lines of the other two positioning rods 5 are in another vertical plane, and the two vertical planes are perpendicular to each other.
