Description

Technical Field

[0001] The invention belongs to the technical field of construction engineering, and specifically discloses a mould for producing an anti-floating anchor rod socket-and-spigot prefabricated grouting body. Background Art

[0002] The application of prestressed anti-floating anchor rods in engineering is to solve the problem of buildings floating due to groundwater pressure. After the pressure-type prestressed anti-floating anchor rod is prestressed, the anti-floating anchor rod becomes an active load-bearing rod, and the anchor rod is in a compression state throughout its life cycle. There is no concern about the grouting body cracking and causing the rod body to rust. However, traditional prestressed anti-floating anchor rods have some problems and limitations during the construction process, such as the construction process is too complicated, and there may be hidden dangers of water seepage and bearing capacity defects after construction. In order to solve the above problems, the applicant applied for a Chinese invention patent: an anti-floating anchor rod based on a socket-type segmented prefabricated grouting body (application number 2024111316270), which has the following advantages compared to ordinary full-length pressure-type post-tensioned prestressed anti-floating anchor rods:

[0003] 1) The factory-prefabricated grouting body is used, and its pouring and curing quality can be controlled. The grouting body has high strength and no cracks.

[0004] 2) The lateral friction between the grouting body and the bearing layer is fully utilized, which greatly improves the pull-out bearing capacity of the anti-floating anchor.

[0005] However, the implementation of the above patent application requires prefabricating the grouting body in sections according to the design requirements, and then sequentially carrying out the rope threading, anchor threading, initial tensioning, grouting, and tensioning and locking construction of the prefabricated grouting body. However, the existing technology lacks corresponding equipment for prefabricating grouting bodies in sections. Usually, the grouting body is prefabricated by assembling simple molds made of cast iron pipes and steel plates at the construction site. Not only is the prefabrication efficiency unreliable, but the quality of the prepared prefabricated grouting body is also difficult to control, thus limiting its application in socket-type anti-floating anchor rods. Summary of the Invention

[0006] In view of the above problems, the present invention aims to provide a standardized mold for producing anti-floating anchor bolt socket-type prefabricated grouting body.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0012] The concave side of the end mold concave portion is penetrated by a grouting pipe positioning hole and a plurality of threading pipe positioning holes arranged around the grouting pipe positioning hole;

[0013] One end of the anchor hole grouting pipe embedded in the prefabricated grouting body is plugged into the grouting pipe joint, and the other end is plugged into the grouting pipe positioning hole. One end of the wire threading pipe embedded in the prefabricated grouting body is plugged into the wire threading pipe joint, and the other end is plugged into the wire threading pipe positioning hole, so that the anchor hole grouting pipe, the water inlet channel, the diversion cavity, the water outlet channel and the wire threading pipe are connected in sequence to form a water flow path, which is used to circulate heat transfer medium through the anchor hole grouting pipe port located at the grouting pipe positioning hole after the prefabricated grouting body is poured to heat or cool the prefabricated grouting body.

[0014] Preferably, the side mold includes a lower side mold whose bottom side wall is fixedly connected to the top of the template support, and an upper side mold with a detachable sealing cover that is engaged with the top of the lower side mold.

[0043] The concave side of the end mold concave portion 404 is penetrated by a grouting pipe positioning hole 4041 and a plurality of threading pipe positioning holes 4042 arranged around the grouting pipe positioning hole 4041;

[0044] One end of the anchor hole grouting pipe 6 pre-buried in the prefabricated grouting body 5 is plugged into the grouting pipe joint 4033, and the other end is plugged into the grouting pipe positioning hole 4041. One end of the threading pipe 7 pre-buried in the prefabricated grouting body 5 is plugged into the threading pipe joint 4034, and the other end is plugged into the threading pipe positioning hole 4042, so that the anchor hole grouting pipe 6, the water inlet channel 4036, the diversion cavity 4035, the water outlet channel 4037 and the threading pipe 7 are connected in sequence to form a water flow path, so that after the prefabricated grouting body is poured, a heat transfer medium can be circulated through the anchor hole grouting pipe 6 pipe port located at the grouting pipe positioning hole 4041 to heat or cool the prefabricated grouting body 5 for curing;

[0045] The bottom plate 1 and the side mold 2 are both made of steel plates or cast iron plates, and the side mold 2 is a cylindrical structure as a whole; the left end mold 401 and the right end mold 402 are made of hard plastic; grouting holes are provided on the side mold 2 or the end mold 4; the diameter of the grouting pipe positioning hole 4041 should be slightly larger than the outer diameter of the anchor hole grouting pipe, and the diameter of the threading pipe positioning hole 4042 should be slightly larger than the outer diameter of the threading pipe;

[0046] Based on the above structural setting, the steps for making a socket-type prefabricated grouting body using the mold of the present invention are as follows:

[0047] S1. Applying mold release agent: Select a side mold 2 of appropriate length according to the length of the prefabricated grouting body, and apply mold release agent to the inner wall of the side mold 2, the inner wall of the left end mold 401, the inner wall of the right end mold 402, the end mold convex part 403, the end mold concave part 404, the threading pipe die head 4032, and the grouting pipe die head 4031;

[0048] S2. Install the left end formwork and the anchor hole grouting pipe and threading pipe: Please refer to Figure 7 and Figure 8 , plug one end of the anchor hole grouting pipe 6 into the grouting pipe joint 4033 on the end mold convex part 403 of the left end mold 401, so that the grouting pipe joint 4033 is inserted into the anchor hole grouting pipe 6, and at the same time plug one end of the threading pipe 7 into the threading pipe joint 4034 on the end mold convex part 403 of the left end mold 401, so that the threading pipe joint 4034 is inserted into the threading pipe 7. At this time, the anchor hole grouting pipe 6 and the threading pipe 7 are both installed on the left end mold 401, and then the anchor hole grouting pipe 6 and the threading pipe 7 are inserted into the inside of the side mold 2 from the left side, and at the same time, the left end mold 401 is sealed and embedded in the left end of the side mold 2, wherein the length of the threading pipe 7 and the anchor hole grouting pipe 6 should be greater than the length of the side mold 2 by 5-10 cm; in addition, please refer to Figure 12 , for the uppermost prefabricated grouting body 5 at the orifice of the anchor hole 11, it is necessary to simultaneously install the upper threaded bar 12 in this step; for the lowermost prefabricated grouting body 5 at the bottom of the anchor hole 11, it is necessary to simultaneously install the lower threaded bar 13, the prestressed bar extrusion anchor 14, and the unbonded steel strand 15 to replace the threading tube in this step, wherein one end of the unbonded steel strand 15 is connected to the prestressed bar extrusion anchor 14, and the other end needs to pass through the threading tube positioning hole of the right end mold to form a free end;

[0049] S3, install the right end mold: After completing the above steps, the other ends of the threading tube 7 and the anchor hole grouting tube 6 are exposed outside the right end of the side mold 2. At this time, insert the other end of the anchor hole grouting tube 6 into the grouting tube positioning hole 4041 of the end mold recess 404 of the right end mold 402, and insert the other end of the threading tube 7 into the threading tube positioning hole 4042 of the end mold recess 404 of the right end mold 402. Then, slowly push the right end mold 402 toward the side mold 2. The right end mold 402 is sealed and embedded into the right end of the side mold 2. At the same time, paraffin is filled in the gap between the threading tube 7 and the threading tube positioning hole 4042 and the gap between the anchor hole grouting tube 6 and the grouting tube positioning hole 4041, or a sealing gasket is sleeved on the outer wall of the threading tube 7 and the outer wall of the anchor hole grouting tube 6 to prevent the slurry from leaking from the grouting tube positioning hole 4041 and the threading tube positioning hole 4042 during subsequent grouting. In this way, the preliminary installation of the mold of the present invention is completed;

[0050] S4, grouting: Fill the cylindrical cavity formed by the left end mold 401, the right end mold 402 and the side mold 2 with cement mortar through the grouting holes provided on the side mold 2 or the end mold 4;

[0051] S5. Post-curing: When the cement mortar is initially solidified and needs to be cured, a heat transfer medium can be circulated through the nozzle of the anchor hole grouting pipe 6 at the grouting pipe positioning hole 4041 according to the ambient temperature. Usually, the heat transfer medium is clean water. The heat transfer medium first flows into the diversion cavity 4035 through the anchor hole grouting pipe 6 and the water inlet channel 4036, and then flows out through the water outlet channel 4037 and the threading pipes 7. This can achieve cyclic heating or cooling of the interior of the prefabricated grouting body 5 to ensure the processing quality of the prefabricated grouting body.

[0052] S6. Demolding: detach the left end mold 401 and the right end mold 402 from both ends of the side mold 2 respectively, and then take out the prefabricated grouting body that has reached the strength and is formed from one side of the side mold.

[0053] Further, in a preferred embodiment, see Figure 4 and Figure 6 The side form 2 includes a lower side form 201 whose bottom side wall is fixedly connected to the top of the formwork support 3, and an upper side form 202 that can be removably sealed and covered on the top of the lower side form 201; based on the above structure, since the upper side form 202 can be removable, it is convenient to apply a release agent on the inner wall of the side form 2 and clean its inner wall, as well as to install upper threaded bars, lower threaded bars, prestressed bar extrusion anchors, etc. in the prefabricated grouting body at special positions. At the same time, it is also convenient to demold the prefabricated grouting body after it reaches strength forming.

[0054] Further, in a preferred embodiment, see Figure 4 and Figure 6A grouting exhaust hole 2021 is provided in the middle of the top surface of the upper side mold 202; when grouting is performed in the cylindrical cavity formed by the left end mold 401, the right end mold 402 and the side mold 2 through the grouting hole, the gas in the cylindrical cavity can be discharged through the grouting exhaust hole 2021, and at the same time, it can be monitored whether the cylindrical cavity is filled with cement mortar through the grouting exhaust hole 2021.

[0055] In order to more conveniently seal the upper mold 202 on the top of the lower mold 201, further, in a preferred embodiment, refer to Figure 4 and Figure 6 One side of the upper mold 202 is hingedly connected to one side of the lower mold 201, and the other side is connected to the other side of the lower mold 201 by a buckle or bolt.

[0056] Further, in a preferred embodiment, see Figure 1 , the left end mold 401 and the right end mold 402 can slide laterally along the inside of the side mold 2, and the two ends of the base plate 1 are provided with a driving mechanism 8 for driving the left end mold 401 or the right end mold 402 to slide laterally; based on this setting, the driving mechanism 8 drives the left end mold 401 and the right end mold 402 to slide laterally inside the side mold 2, so that the length of the processed prefabricated grouting body can be flexibly adjusted; preferably, the driving mechanism 8 is a self-locking hydraulic telescopic cylinder.

[0057] Further, in a preferred embodiment, see Figure 1 A mold grouting pipe 405 is horizontally provided through the top of the left end mold 401 and the right end mold 402; based on this setting, not only can the grouting position adapt to the change in the length of the prefabricated grouting body caused by the movement of the left end mold and the right end mold, but grouting can also be carried out synchronously from the left and right ends to ensure the uniformity of cement mortar injection.

[0058] Further, in a preferred embodiment, see Figure 1 and Figure 4 The present invention also includes a water collecting trough 9, which is connected to the right end of the side form 2, and a drainage pipe 10 is provided at the bottom of the water collecting trough 9; when the heat transfer medium is circulated into the anchor hole grouting pipe 6 during the maintenance process, the heat transfer medium flowing out of the threading pipe 7 can be collected through the water collecting trough 9 and finally discharged through the drainage pipe 10, thereby preventing the heat transfer medium from polluting the construction site.

[0059] Further, in a preferred embodiment, see Figure 8 and Figure 11, the outer diameter of the grouting pipe die head 4031 is the same as the outer diameter of the anchor hole grouting pipe 6, and the outer diameter of the threading pipe die head 4032 is the same as the outer diameter of the threading pipe 7; the length of the grouting pipe die head 4031 is less than or equal to the depth of the grouting pipe positioning hole 4041, and the length of the threading pipe die head 4032 is less than or equal to the depth of the threading pipe positioning hole 4042; based on the above settings, when the mold of the present invention is used to process the prefabricated grouting body, the concave socket joint 501 of the prefabricated grouting body corresponding to the left end mold 401 will reserve an anchor hole grouting pipe jack 5011 with the same outer diameter as the grouting pipe die head 4031, and reserve a groove 5011 with the same outer diameter as the threading pipe die head 40 32 outer diameter of the threading pipe socket 5012; and when removing the mold, the excess anchor hole grouting pipe and threading pipe exposed outside the right end mold 402 can be cut off. At this time, after the right end mold 402 is removed, the convex socket joint 502 of the prefabricated grouting body corresponding to the right end mold 402 will just expose part of the anchor hole grouting pipe and threading pipe. In this way, when the concave and convex socket joints of the prefabricated grouting body are plugged in, the exposed anchor hole grouting pipe and threading pipe can be plugged into the anchor hole grouting pipe socket 5011 and the threading pipe socket 5012 respectively at the same time, so that the anchor hole grouting pipe and threading pipe inside the two prefabricated grouting bodies that are plugged in to each other are connected to each other.

[0060] In order to make the anchor hole grouting pipe 6 and the grouting pipe joint 4033 sealed and the threading pipe 7 and the threading pipe joint 4034 sealed, further, in a preferred embodiment, refer to Figure 8 and Figure 11 The outer diameter of the grouting pipe joint 4033 is the same as the inner diameter of the anchor hole grouting pipe 6, and the outer diameter of the threading pipe joint 4034 is the same as the inner diameter of the threading pipe 7.

[0061] Furthermore, in a preferred embodiment, the anchor hole grouting pipe 6 and the threading pipe 7 are both PVC pipes. Example 2

[0064] S2. Threading the prefabricated grouting bodies: After all the prefabricated grouting bodies 5 are completed, the free ends of the unbonded steel strands 15 reserved in the lowest section of the prefabricated grouting body 5 are threaded into the threading pipes 7 of the remaining prefabricated grouting bodies 5 from bottom to top. At this time, the anchor hole grouting pipes 6 in the multiple sections of the prefabricated grouting bodies 5 are connected from top to bottom and threaded together by the unbonded steel strands 15;
