Detailed Description
The utility model is further described in detail below with reference to the accompanying drawings, and specific embodiments are given.
Example 1
As shown in fig. 1, the fabricated building pressure grouting structure includes a grouting unit and a sealing unit, the grouting unit includes an upper member 1, a lower member 2, a sleeve 7 embedded in the upper member 1, and a reinforcing bar 6 embedded in the lower member 2, the sleeve 7 is inserted by the reinforcing bar 6, and a grouting area 5 is formed between the upper member 1 and the lower member 2. In the actual manufacturing process, a plurality of sleeves 7 are arranged on the upper member 1, and correspondingly, a plurality of reinforcing steel bars 6 are arranged on the lower member 2.
The grouting unit further comprises a grouting nozzle 11 for grouting and a grouting channel 8 arranged on the upper member 1, the lower end of the grouting channel 8 is communicated with the grouting area 5, the lower end opening of the grouting channel 8 is positioned in the center of the grouting area 5, and the horizontal height of the upper end of the grouting channel 8 is higher than that of the upper end of the sleeve 7. The upper component 1 is provided with a grouting hole 9 for grouting on one side of the grouting end of the grouting channel 8 and one side of the grouting end of the sleeve 7, and the grouting hole 9 is horizontal. The upper member 1 is located the grout hole 9 outside and is seted up the thread groove 10 that is used for with grout mouth 11 threaded connection, and is specific, and grout mouth 11 outer wall is equipped with the external screw thread, and grout mouth 11 outer wall and thread groove 10 are connected. The nozzle 11 is formed in an L-shape, and when the nozzle 11 is coupled to the screw groove 10, the nozzle 11 is rotated such that the opening of the nozzle 11 faces upward.
As shown in fig. 2, the grout inlet end of the grout hole 9 is provided with an expanding portion 12 with an isosceles trapezoid cross section, the inner wall of the grout nozzle 11 is provided with a sealing ring 13 for being attached to the inner wall of the expanding portion 12, and when the sealing ring 13 abuts against the inner wall of the expanding portion 12, the inner side of the sealing ring 13 forms a circular truncated cone-shaped space with the minimum inner diameter not larger than the inner diameter of the grout hole 9. In this embodiment, the sealing ring 13 is fixed to the inner wall of the nozzle 11. A valve is installed in the grouting nozzle 11.
The sealing unit serves to seal the gap between the upper and lower members 1, 2, i.e., to seal the circumferential direction of the grout region 5, so that the grout can enter and fill the grout region 5. The sealing unit comprises a sealing plate 3 detachably connected with the outer walls of the upper member 1 and the lower member 2, one end of the sealing plate 3 is in bolted connection with the outer wall of the upper member 1, and the other end of the sealing plate 3 is in bolted connection with the outer wall of the lower member 2. The expansion water stop strip 4 is fixed to one side of the sealing plate 3 facing the grouting area 5, and after the sealing plate 3 is mounted on the upper member 1 and the lower member 2, the expansion water stop strip 4 is inserted into the grouting area 5.
When the combined type steel bar hoisting device is used specifically, the upper member 1 is hoisted to the lower member 2, and meanwhile, the steel bars 6 on the lower member 2 are inserted into the sleeves 7 on the upper member 1. The sealing plate 3 is installed such that the expansion seal 4 is interposed between the upper member 1 and the lower member 2.
At the time of primary grouting, a grouting nozzle 11 is installed to the grouting hole 9 communicating with the sleeve 7 so that the seal ring 13 abuts against the flared portion 12 of the grouting hole 9. If a plurality of sleeves 7 are arranged on the upper component 1, a grouting nozzle 11 is communicated with a grouting hole 9 communicated with one sleeve 7, slurry is introduced through the grouting nozzle 11, the slurry enters a grouting area 5 through the grouting nozzle 11, the grouting hole 9 and the sleeve 7 in sequence, after the grouting area 5 is filled with the slurry, the sleeve 7 and a grouting channel 8 are filled with the slurry along with the continuous introduction of the slurry, after the slurry is discharged from other grouting holes 9 communicated with the sleeve 7, the corresponding grouting hole 9 is closed (for example, blocked by a plug) by the conventional means in the prior art, because the height of the upper end of the grouting channel 8 is higher than that of the upper end of the sleeve 7, the slurry is filled in the sleeve 7 and the grouting hole 9 communicated with the sleeve 7, and then the slurry is filled in the grouting channel 8 after the slurry is continuously introduced, and when the slurry flows out from the grouting channel 8, the grouting hole 9 communicated with the grouting channel 8 is closed. While simultaneously closing the valve in the nozzle 11 or, after removing the nozzle 11, closing the grouting hole 9 (for example by plugging) by conventional means of the prior art.
Waiting for the thick liquids to condense, after the thick liquids condense, open the grout hole 9 and with grout passageway 8 intercommunication and install grout mouth 11 to this grout hole 9, begin the grout for the second time, because the thick liquids is at the coagulation process, probably flow downwards (or to the infiltration of flowing in other gaps), lead to partial region unable complete filling, can lead to sleeve pipe 7 not full of being in the milk, carry out the secondary grout through grout passageway 8 this moment, the thick liquids gets into in grout passageway 8, form certain pressure, and infiltration downwards, get into sleeve pipe 7, in the grout region 5, fill the space.
Above-mentioned grout in-process, in grout mouth 11 entering grout hole 9, extrusion sealing ring 13 for sealing ring 13 laminates on flared portion 12 inner walls, avoids in the thick liquids gets into thread groove 10, has just also avoided thick liquids to influence grout mouth 11 dismantlements.
Example 2
This example differs from example 1 in that: the grouting nozzle 11 is arranged differently, and as shown in fig. 3 and 4, in this embodiment, the grouting nozzle 11 includes a threaded cylinder 14 connected with the threaded groove 10 and a grouting cylinder 15 inserted into the threaded cylinder 14, and the sealing ring 13 is adhered to the end face of the grouting cylinder 15. The 14 inner walls of a screw thread section of thick bamboo are equipped with the caulking groove that supplies grout section of thick bamboo 15 embedding, sealing ring 13 includes the butt portion that offsets with the caulking groove inner wall, during the installation, connect screw thread section of thick bamboo 14 in screw thread groove 10 earlier, then with grout section of thick bamboo 15 disect insertion screw thread section of thick bamboo 14 in, make the butt portion and the caulking groove inner wall of sealing ring 13 offset and form sealedly, then accessible conventional mode is fixed grout section of thick bamboo 15, for example, through bolted connection, magnetism is inhaled modes such as fixed, can be directly through artifical handheld grout section of thick bamboo 15, as long as make the butt portion and the caulking groove inner wall of sealing ring 13 offset can.
Compared with the embodiment 1, the installation of the sealing ring 13 is facilitated firstly, the sealing ring 13 is bonded at the end part of the grouting cylinder 15, the sealing ring 13 is also convenient to tear off or cut off the sealing ring 13 to replace the new sealing ring 13 when needing to be replaced, and compared with the sealing ring 13 which is arranged inside the grouting nozzle 11, the installation is more convenient; secondly also be convenient for when grout nozzle 11 installs, sealing ring 13 offsets with the flaring portion 12 inner wall of grout hole 9, in this embodiment, grout section of thick bamboo 15 directly do the horizontal motion of male can, and need not sealing ring 13 and rotate along with it, more be convenient for insert sealing ring 13.
