Referring to fig. 1-4, an easily detachable steel pipe scaffold comprises a partition board 1, an inner pipe 2 is fixedly connected to the top and the bottom of the partition board 1, an outer jacket 3 is fixedly connected to the top and the bottom of the partition board 1, the circle center of the outer jacket 3 and the circle center of the inner pipe 2 are in the same axial direction, and a vertical rod 4 is sleeved on the outer side of the inner pipe 2.

In this embodiment, as shown in fig. 1, 2 and 3, the outer side of the outer jacket 3 is symmetrically provided with vertical slots 31 about the center of a circle, the left and right sides of the bottom of each vertical slot 31 are fixedly provided with horizontal slots 32, the outer side of the outer jacket 3 is symmetrically welded with positioning blocks 33 about the center of a circle, and the middle parts of the positioning blocks 33 are sleeved with positioning bolts 34.

Through the cooperation of locating piece 33 and pilot pin 34, the one end of pole setting 4 cup joints in the outside of inner tube 2, and outer jacket 3 is crooked in cross slot 32 department this moment, accomplishes the top that outer jacket 3 held pole setting 4 with, realizes the quick assembly disassembly of two pole settings 4 at the top and the bottom of baffle 1.

In this embodiment, as shown in fig. 4, an open groove 35 is fixedly disposed on one side of the outer jacket 3, positioning plates 36 are symmetrically welded on the outer side of the outer jacket 3 with respect to the open groove 35, a positioning bolt 34 is sleeved on the middle portion of the positioning plate 36, and a limiting block 37 is welded on the opposite side of each of the two positioning plates 36.

Pole setting 4 cup joints in the outside of inner tube 2, and locating plate 36 cooperates with locating pin 34, realizes that stopper 37 contradicts in the outside of pole setting 4 towards one side of outer jacket 3 inner wall, accomplishes the quick assembly disassembly of pole setting 4 at the top and the bottom of baffle 1.

In this embodiment, as shown in fig. 1 and fig. 2, a positioning groove 361 is fixedly disposed in the middle of the positioning plate 36, and the rear portion of the positioning groove 361 extends downward from horizontal.

The cooperation of locating plate 36 and constant head tank 361 makes things convenient for the shelf worker when the dismouting, improves the dismouting efficiency between pilot pin 34 and the locating plate 36.

In this embodiment, as shown in fig. 1, 2 and 3, the top end of the inner tube 2 is an inner annular abutting surface with a high inside and a low outside, and the outer surface of the inner tube 2 is subjected to oxidation blackening treatment.

Interior annular butt joint face that the interior height on inner tube 2 top was low outward makes things convenient for the dismouting that cup joints of pole setting 4 and inner tube 2, and side friction between pole setting 4 and the inner tube 2 leads to the unable rust-resistant treatment of realizing through the mopping in surface of inner tube 2, so take oxidation blackening to handle on the surface of inner tube 2, improve the outer surface abrasion resistance and the anti-corrosion performance of inner tube 2, avoid the outside of inner tube 2 to take place the iron rust that the corrosion produced and be infected with in the inside of pole setting 4.

In this embodiment, as shown in fig. 1, 2, 3 and 4, the top end of the outer jacket 3 is an outer annular abutting surface with a low inside and a high outside.

The top end structure of the outer jacket 3 is an outer annular butt joint surface with a low inner part and a high outer part, so that the upright rod 4 is conveniently sleeved on the inner side of the outer jacket 3.

In this embodiment, as shown in fig. 1 and 2, the positioning block 33 is symmetrical with respect to the vertical slot 31, and a reinforcing rib is welded at a joint of the positioning block 33 and the outer jacket 3.

During the initial installation, the cooperation of locating piece 33 and outer jacket 3, because of the cooperation of outer jacket 3 and transverse groove 32, so locating piece 33 drives the structure that outer jacket 3 is located the transverse groove 32 top and twists reverse under the fastening of locating bolt 34, realizes the centre gripping of the top of outer jacket 3 to pole setting 4, and wherein the cooperation of transverse groove 32 and perpendicular groove 31 makes things convenient for outer jacket 3 to twist reverse and takes place the deformation.

In the follow-up installation, pole setting 4 covers in the outside of inner tube 2, and wherein the top joint that the overcoat presss from both sides cover 3 is in the outside of pole setting 4, and further improvement this device's follow-up use dismouting in-process, the protection of dropping is prevented to the centre gripping of pole setting 4.

In this embodiment, as shown in fig. 4, the side of the limiting block 37 facing the inner wall of the outer jacket 3 is fixedly provided with anti-slip threads.

The positioning plate 36 is matched with the positioning bolt 34, the outer jacket 3 is matched with the open groove 35, the structural strength is higher than that of the outer jacket 3, the vertical groove 31 and the transverse groove 32, the positioning plate 36 is twisted outside the open groove 35 of the outer jacket 3, the limiting block 37 is abutted against the vertical rod 4, the part, close to the top of the open groove 35, of the outer jacket 3 is twisted under the fastening action of the positioning bolt 34, and the opposite rod 4 is pre-clamped.

This device is as the connection structure of the drawknot point of pole setting 4, need bear steel pipe scaffold's the perpendicular and ascending effort of horizontal direction, still need bear and transmit wind load, wherein steel pipe scaffold's load transmission way does, the ascending load of vertical direction passes through right angle fastener and transmits to the pole setting on, the ascending load of horizontal direction passes through the drawknot point and transmits for in the pole setting, the whole atress system of steel pipe scaffold is eccentric pressurized in addition, the lateral deformation of pole setting 4 has horizontal pole and right angle fastener restraint, so this device need ensure the installation stability of pole setting 4, baffle 1, the cooperation of inner tube 2 and jacket 3, improve the installation stability of pole setting 4, avoid many pole settings 4 to appear the centre of a circle skew of many pole settings 4 in the installation, influence the load transmission among the atress system of whole steel pipe scaffold.

This device is limited to the installation use of pole setting 4 only in actual installation, because of horizontal pole and the atress condition of bridging in steel pipe scaffold is different with the atress condition of pole setting 4, can not be used to the buildding of horizontal pole and bridging.

The above-mentioned embodiments only express a certain implementation mode of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention; it should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which shall fall within the protective scope of the invention; therefore, the protection scope of the present patent shall be subject to the appended claims.
