The locking seat includes a cylinder, an unlocking mechanism, and an external screw located at the lower end of the cylinder. The upper part of the cylinder is a slot one for inserting a larger outer diameter steel pipe, the middle part is a slot two for inserting a smaller outer diameter steel pipe, and the lower part is an installation space. The inner walls of slot one and slot two are provided with barbs for locking the steel pipes. The unlocking mechanism includes a mechanism located on the cylinder with its operating end positioned on the cylinder. The external operating components, transmission components, and top block located within the installation space are used to push the steel pipe out when the operating components are unlocked by driving the top block upward through the transmission components. The pre-embedded base includes a pre-embedded threaded cylinder that can cooperate with the external screw and has a sealed lower end, and a positioning block on the outer wall of the pre-embedded threaded cylinder for positioning the pre-embedded height. The adjustable base includes two facing clamps, a threaded cylinder on the outside of one clamp that can cooperate with the external screw, a telescopic rod that is hinged between the same side of the two clamps and has an adjustable length, and a pull screw for pulling and locking the other side of the two clamps when the two clamps are attached to the steel component.
[0006] Preferably, slot one is adapted to a φ60mm steel pipe, and slot two is adapted to a φ48mm steel pipe.
[0007] Preferably, the area where slot one and slot two are located on the insert tube adopts a segmented structure. The segmented block is hinged to the lower structure of the insert tube at the bottom outer side and can be locked. After the segmented block is unlocked, it can separate outward around the hinge point.

[0011] Preferably, one end of the pull screw passes through a round hole in one clamping plate, and the other end passes through a waist hole in another clamping plate.
[0012] A method for installing steel pipes, based on the aforementioned steel pipe installation components;
[0013] When installing steel pipes on concrete components: Before pouring concrete components, first embed a pre-embedded base, and connect it to the internal steel bars of the concrete component through its positioning block, and ensure that the upper end of the pre-embedded threaded cylinder is flush with the design elevation of the concrete component; after the concrete component is poured and reaches the design strength, first install the external screw of the locking seat on the pre-embedded threaded cylinder, and then insert a steel pipe of one of the two outer diameters into the cylinder and lock it.
[0014] When disassembling steel pipes on concrete components: first operate the operating component, which drives the top block to move upward through the transmission component to push the steel pipe out; then remove the external screw of the locking seat from the pre-embedded threaded cylinder; then fill and seal the pre-embedded threaded cylinder, leaving the pre-embedded base inside the concrete component; and then retrieve the locking seat.
[0015] When installing steel pipes on steel components: First, adjust the length of the telescopic rod between the same side of the two clamping plates so that the two clamping plates fit together and are clamped on the steel component. Then, use the pull screw to pull and lock the other side of the two clamping plates. Then, install the external screw of the locking seat on the threaded cylinder.

Finally, retrieve the locking seat and the adjustable base.
[0017] The beneficial effects of this invention are:
[0018] When used on concrete components, this component will not damage the concrete structure during the installation or removal of steel pipes. When used on steel components, it will not involve welding operations or damage the steel structure during the installation or removal of steel pipes. The locking seat in this component can accommodate two types of steel pipes with different outer diameters, thus expanding its applicability. The locking seat can be connected to a pre-embedded base in the concrete component via threads, and it can also be connected to an adjustable base locked in the steel component via threads. In addition, the locking seat can lock the steel pipe with the back teeth on the slot and can push the steel pipe out with the top block, making the installation and removal of steel pipes very convenient.

[0028] The present application will be further described below with reference to the accompanying drawings and embodiments.
[0029] This application discloses a steel pipe installation assembly, comprising three main parts: a locking seat, a pre-embedded base, and an adjustable base; wherein: as shown in the figure... Figure 1 and Figure 2As shown, the locking seat is used to lock two types of steel pipes with different outer diameters. The locking seat includes a cylinder 11, an unlocking mechanism, and an external screw 12. The upper part of the cylinder 11 has a slot 111 for inserting a larger outer diameter steel pipe, the middle part has a slot 112 for inserting a smaller outer diameter steel pipe, and the lower part is the installation space. The inner walls of slots 111 and 112 are provided with reverse teeth a for locking the steel pipe. The unlocking mechanism includes an operating component, a transmission component, and a top block 13. The operating component is located on the cylinder 11 with its operating end outside the cylinder 11. The transmission component and the top block 13 are located within the installation space. When unlocking, the operating component drives the top block 13 upward through the transmission component to push the steel pipe out. The external screw 12 is located at the lower end of the cylinder 11. Figure 3 As shown, the embedded base is used to provide a connection port for the steel pipe locking seat on the concrete component. The embedded base includes an embedded threaded cylinder 21 and a positioning block 22. The embedded threaded cylinder 21 can cooperate with the external screw 12 and its lower end is sealed. The positioning block 22 is provided on the outer wall of the embedded threaded cylinder 21 and is used to position the embedded height. Figure 4 As shown, the adjustable base is used to provide a connection port for the steel pipe locking seat on the steel component. The adjustable base includes a clamping plate 31, a threaded cylinder 32, a telescopic rod 33, and a pull screw 34. The two clamping plates 31 face each other. The threaded cylinder 32 is located on the outside of one clamping plate 31 and can cooperate with the external screw 12. The telescopic rod 33 is hinged between the same side of the two clamping plates 31 and its length is adjustable. The pull screw 34 is used to pull and lock the other side of the two clamping plates 31 when the two clamping plates 31 are clamped together on the steel component.
[0030] In this embodiment, preferably: slot 111 is adapted to φ60mm steel pipe, and slot 212 is adapted to φ48mm steel pipe, adapting to the two most common types of steel pipe.
[0031] like Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, preferably, the area where slot 111 and slot 212 are located on the insert 11 adopts a split structure. The split block is hinged to the lower structure of the insert 11 at the bottom outer side. After the split block is unlocked, it can be separated outward around the hinge point. When the top block 13 cannot push the steel pipe out, the split block can be separated so that the steel pipe can be taken out.
[0032] like Figure 1 and Figure 2As shown, in this embodiment, preferably: the operating component is a gear 15 with a handle 14, the handle 14 is located outside the insert 11, the gear 15 is rotatably mounted on the insert 11, the operating component is located on both sides of the insert 11, and the transmission component is a transmission cylinder 16 with racks on both sides. The two sides of the transmission cylinder 16 are respectively meshed with the gear 15 through the racks, and the upper end is connected to the top block 13. When both hands press the handles 14 on both sides at the same time, the transmission cylinder 16 and the top block 13 are driven to rise through the rack and pinion transmission of the gear 15.
[0033] like Figure 1 and Figure 2 As shown, in this embodiment, preferably, the transmission cylinder 16 is provided with an assist spring 17. The lower end of the assist spring 17 is limited and the upper end acts on the top block 13. The assist spring 17 can assist in unlocking and reduce the downward pressure required for unlocking.
[0034] like Figure 4 As shown, in this embodiment, preferably, the telescopic rod 33 has an adjusting cylinder 331 in the middle and threaded rods 332 at both ends that are threadedly engaged with the adjusting cylinder 331, with the threads of the threaded rods 332 at both ends reversed. Rotating the adjusting cylinder 331 can adjust the synchronous extension and retraction of the threaded rods 332 at both ends, thereby adjusting the length.
[0035] like Figure 4 As shown, in this embodiment, preferably, one end of the pull screw 34 passes through the round hole of one clamping plate 31 and the other end passes through the waist hole 311 of the other clamping plate 31. When the two clamping plates 31 are tilted relative to each other, the waist hole 311 can adapt to the position change of the pull screw 35 caused by the tilt.
[0036] The installation method for the above-mentioned steel pipe installation components is as follows:
[0037] When installing steel pipes on concrete components (e.g., using steel pipes as uprights for edge protection of floor openings): Before pouring concrete components, first embed a pre-embedded base, and connect it to the internal steel reinforcement of the concrete component through its positioning block 22, and ensure that the upper end of the pre-embedded threaded cylinder 21 is flush with the design elevation of the concrete component; after the concrete component is poured and reaches the design strength, first install the external screw 12 of the locking seat on the pre-embedded threaded cylinder 21, and then insert a steel pipe of one of two outer diameters into the insert 11 and lock it.
[0038] When disassembling steel pipes on concrete components: first operate the operating component, which drives the top block 13 to move upward through the transmission component to push the steel pipe out; then remove the external screw 12 of the locking seat from the pre-embedded threaded cylinder 21; then fill and seal the pre-embedded threaded cylinder 21, leaving the pre-embedded base inside the concrete component; and then retrieve the locking seat.
[0039] When installing steel pipes on steel components (e.g., using steel pipes as the main components of cantilevered steel scaffolding): first adjust the length of the telescopic rod 33 between the same side of the two clamping plates 31 so that the two clamping plates 31 are clamped together on the steel component. Then use the tie rod 34 to pull and lock the other side of the two clamping plates 31. Then install the external screw 12 of the locking seat on the threaded cylinder 32. Then insert one of the two outer diameter steel pipes into the insert cylinder 11 and lock it.
[0040] When disassembling the steel pipe from the steel component: first operate the operating component, which drives the top block 13 to move upward through the transmission component to push the steel pipe out, then remove the external screw 12 of the locking seat from the threaded cylinder 32, then disassemble the pull screw 34 to detach the two clamping plates 31 from the steel component, and retrieve the locking seat and adjustable base.
[0041] When used on concrete components, this component will not damage the concrete components during the installation or removal of steel pipes. When used on steel components, there will be no welding operations during the installation or removal of steel pipes, and the steel components will not be damaged. The locking seat in this component can accommodate two types of steel pipes with different outer diameters, thus expanding its applicability. The locking seat can be connected to a pre-embedded base in the concrete component via threads, and it can also be connected to an adjustable base locked in the steel component via threads. In addition, the locking seat can lock the steel pipe with the back teeth a on the slot and can push the steel pipe out with the top block 13, making the installation and removal of the steel pipe very convenient.
