[0043] Embodiment 1
[0044] The embodiment 1 provides a prefabricated concrete column connecting structure of hole pipe-shaped sleeve joint instead of reinforcing steel, as shown in Figures 1-6 The specific structure is described as follows.
[0045] Please refer to Figure 1 The prefabricated concrete column connecting structure of hole pipe-shaped sleeve joint instead of reinforcing steel of the embodiment 1 mainly comprises two parts of sleeve one 1 and sleeve two 2, which are used for connecting the upper column one 3 and the lower column two 4.
[0046] The material of the sleeve one 1 and the sleeve two 2 can preferably be Q355B grade steel material, the sleeve one 1 and the sleeve two 2 can be welded into square tube (or rectangular tube) shape by four steel plates, or directly cut into circular tube form by profiled steel pipe. Combined with Figure 1 As shown in
[0047] Similarly, combined with Figure 1 As shown in The bottom end of the sleeve two 2 is inserted into the inside of the column two 4 and is fixed by pre-buried, and the longitudinal reinforcement two 401 inside the column two 4 is fixed with the inner wall of the sleeve two 2 by double-sided welding, so that the stability of the connection between the sleeve two 2 and the column two 4 is ensured.
[0048] Further, combined with Figure 1 As shown in The outer diameter of the sleeve one 1 is smaller than the inner diameter of the sleeve two 2, so that the sleeve one 1 can be inserted from the top of the sleeve two 2, and the sleeve one 1 and the sleeve two 2 are sleeved. Through the restriction of the sleeve two 2 to the sleeve one 1, the column one 3 after sleeving saves the material and labor cost of site erection support.
[0049] Referring toFigure 1 and Figure 2 As shown in the figure, a top partition plate 202 and a bottom partition plate 203 are installed inside the pipe sleeve two 2, the top partition plate 202 is located on the upper side of the bottom partition plate 203, the bottom of the top partition plate 202 is connected with the top of the column two 4, and the bottom of the sleeve one 1 is supported by the top of the top partition plate 202.
[0050] Further, the edge of the bottom partition plate 203 is provided with the same number of through holes 2031 according to the position of the longitudinal reinforcement two 401, and the longitudinal reinforcement two 401 passes through the through holes 2031. Figure 2 As shown in the figure, eight through holes 2031 are uniformly arranged on the edge of the bottom partition plate 203, and the longitudinal reinforcement two 401 passes through the through holes 2031, so that the bottom partition plate 203 does not affect the connection between the longitudinal reinforcement two 401 and the pipe sleeve two 2.
[0051] As shown in the figure, the top partition plate 202 and the bottom partition plate 203 can also be used to indirectly connect the upper and lower flanges of the beam connecting web plate 9, and enhance the node stiffness of the column and beam connection. Figure 1 As shown in the figure, the beam connecting web plate 9 is made of I-beam, the end of the beam is connected with the beam connecting web plate 9, the beam connecting web plate 9 is connected with the side wall of the pipe sleeve two 2, and the connection mode can be welding or bolt connection. The connection position of the top of the beam connecting web plate 9 and the pipe sleeve two 2 is flush with the top partition plate 202, and the connection position of the bottom of the beam connecting web plate 9 and the pipe sleeve two 2 is flush with the bottom partition plate 203.
[0052] It should be noted that a larger circular hole is arranged at the center of the top partition plate 202 and the bottom partition plate 203 (which can also be arranged at other positions), so as to facilitate the pouring of the column two 4 itself. When the prefabricated column two 4 is delivered, the concrete is poured to the lower surface of the top partition plate 202, so that the column two 4 and the pipe sleeve two 2 form an integral whole and have sufficient stiffness to meet the use requirements.
[0053] As shown in the figure, when the pipe sleeve one 1 and the pipe sleeve two 2 are sleeved, there is a millimeter-level error gap between the pipe sleeve one 1 and the pipe sleeve two 2, at this time, the alignment accuracy between the pipe sleeve one 1 and the pipe sleeve two 2 can be adjusted, such as the perpendicularity of the pipe sleeve one 1, and then the gasket 8 is inserted into the gap between the pipe sleeve one 1 and the pipe sleeve two 2 for fixation, and the concrete is poured to ensure that the alignment accuracy remains unchanged. Figure 1 In order to make the pipe sleeve one 1 and the pipe sleeve two 2 have better bonding effect with the poured concrete, the surface of the pipe sleeve one 1 and the pipe sleeve two 2 is provided as a concave-convex surface, that is, the surface is uneven, and the concave-convex surface increases the contact area and has better bonding effect. The surface of the pipe sleeve one 1 and the pipe sleeve two 2 can be made uneven by sandblasting.

The tapered end portion 302 can be in the form of a truncated cone, a cone or a pyramid. The slope of the tapered end portion 302 should be considered to facilitate the smooth pouring of concrete to the top surface. Therefore, in this embodiment, the slope of the tapered end portion 302 is 45°, which ensures the pouring quality. During pouring, the top surface of the concrete is not lower than the slope line of the root of the tapered end portion 302, and the top of the hole one 101 is flush with the slope line of the root of the tapered end portion 302, further improving the pouring quality.

The position and number of the hole one 101 and the hole two 201 are determined comprehensively considering the calculation, structure and connection factors.
[0059] Further, the positions of the hole one 101 and the hole two 201 are as follows: the longitudinal bars one 301 are arranged in a staggered manner with the hole one 101, and the longitudinal bars two 401 are arranged in a staggered manner with the hole two 201, to meet the requirements of stress stiffness and strength. When the cross section of the column one 3 and the column two 4 has three longitudinal bars one 301 and three longitudinal bars two 401 on one side, two holes one 101 and two holes two 201 are formed on the single side panel of the sleeve one 1 and the sleeve two 2, for example Figure 1 As shown, when the cross section of the column one 3 and the column two 4 has four longitudinal bars one 301 and four longitudinal bars two 401 on one side, one or three holes one 101 and one or three holes two 201 are formed on the single side panel of the sleeve one 1 and the sleeve two 2, for example Figure 4 , Figure 5As shown in the drawings.
