Description

Technical Field

[0001] The utility model belongs to the technical field of tools for building construction, in particular to a grouting pipe for building construction. Background Art

[0002] The function of the grouting pipe is to add the flowing slurry in a relatively accurate positioning. Generally, the grouting pipe used for concrete is relatively large in size and is used to cast large concrete structures, while the grouting pipe used for joint filling materials is relatively small in size and is mainly used to fill various gaps in buildings.

[0003] The grouting pipe for the above-mentioned seam-filling material mainly comprises: a pipe body, a trough body, and a spiral blade rod. The general principle of the grouting pipe is: the seam-filling material is first added into the trough body, and then the spiral blade rod is rotated to transport the seam-filling material from the trough body to the front end of the pipe body, and finally accurately sprayed out at the tip of the pipe body to complete the seam-filling grouting operation.

[0004] For example, a Chinese utility model patent with patent publication number CN217151382U and publication date 2022.08.09 discloses a multifunctional grouting pipe for repairing bottom plate leakage, including a fixed pipe, in which a conveying mechanism is inserted, and the conveying mechanism includes a connecting pipe, a rotating rod arranged in the connecting pipe, a spiral blade fixed to one end of the outer wall of the rotating rod, a fixed box inserted and fixed to the other end of the connecting pipe, and a filter assembly inserted in the fixed box.

[0005] The structural principle and advantages of the grouting pipe in this utility model patent are as follows: the filtering component filters the mortar entering the fixed box in advance, filters out the large particles in the mortar, so that the mortar will not cause blockage when passing through the outlet of the conical pipe, and cooperates with the rotating wheel handle to drive the rotating rod and the spiral blade to rotate, so as to transport the mortar in the connecting pipe, which is conducive to the smooth progress of the grouting operation, avoids the time wasted on unblocking and cleaning due to outlet blockage, and is conducive to improving work efficiency.

[0006] However, the grouting pipe has at least the following two shortcomings in the actual construction and use process, which are also the technical problems to be solved by the utility model, namely:

[0007] 1. The entire grouting pipe device lacks the necessary limit frame, so that the distance between the tapered pipe and the gap can only be subjectively controlled by the operator's experience. This error is relatively large, or it is difficult to say that it is easy to cause harmful phenomena such as uneven grouting and grouting belt breakage;

[0008] 2. The relatively large fixed pipe structure is only used to install the tapered pipe at the front end, which is a great waste of materials. In addition, the gap between the fixed pipe and the connecting pipe is prone to material jam.

[0009] Therefore, in summary, there is an urgent need for a new type of grouting pipe equipment with precise grouting operation and relatively reasonable tapered pipe installation structure, which can be used for various seam filling operations during construction. Utility Model Content

[0010] The utility model provides a grouting pipe for building construction, which can be provided with a tapered pipe, a material box, a spiral blade rod, a hand wheel, a positioning ring unit, a vertical frame unit, a fixed circular ring unit, and a connecting ring unit on a pipe body, so that: 1. after the distance between the tapered pipe and the gap is adjusted as needed, it can be stably moved vertically to ensure that the grouting strips are relatively uniform and continuous; 2. The tapered pipe can be simply installed on the pipe body, and the tapered pipe is convenient to disassemble, clean and replace.

[0011] The technical solution adopted by the utility model to solve the above-mentioned problem is: a grouting pipe for construction construction, the structure of which includes a pipe body, a tapered pipe, a material box, a spiral blade rod, and a hand wheel, and also includes a positioning ring unit arranged on the annular surface of the pipe body, a vertical frame unit for engaging the positioning ring unit, a fixed circular ring unit arranged on the inner annular surface of the pipe body and used for inserting and installing the spiral blade rod, and a connecting ring unit arranged on the inner annular surface of the tapered pipe and used for connecting the fixed circular ring unit.

[0012] A further preferred technical solution is that the positioning ring unit includes a lifting ring sleeved on the outer ring surface of the tube body, a limit block arranged on the lifting ring and used to engage the vertical frame unit, and an adjustment ring arranged on the outer ring surface of the tube body and used to clamp the lifting ring.

[0013] A further preferred technical solution is that: a threaded groove for screwing the adjusting ring is provided on the outer ring surface of the tube body; and one adjusting ring is provided on both sides of the lifting ring.

[0014] A further preferred technical solution is that the vertical frame unit includes a base plate, two vertical plates arranged on the base plate and used to engage the lifting ring, and a vertical sliding groove arranged on opposite sides of the vertical plates and used to insert the limit block.

[0015] A further preferred technical solution is that the vertical frame unit further includes a top plate arranged on the upper end surfaces of the two vertical plates, and a positioning groove arranged on the lower surface of the top plate and used for engaging the two vertical plates.

[0031] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0032] As attached Figure 1-6 As shown, a grouting pipe for construction, the structure includes a pipe body 11, a tapered pipe 12, a material box 13, a spiral blade rod 14, and a hand wheel 15, and also includes a positioning ring unit 1 arranged on the outer ring surface of the pipe body 11, a vertical frame unit 2 for engaging the positioning ring unit 1, a fixed circular ring unit 3 arranged on the inner ring surface of the pipe body 11 and used for inserting and installing the spiral blade rod 14, and a connecting ring unit 4 arranged on the inner ring surface of the tapered pipe 12 and used for connecting the fixed circular ring unit 3.

[0033] In this embodiment, the material conveyed by the grouting pipe can be: diatom mud, gypsum slurry, glue, silicone, caulking agent and other common seam-filling materials. The above seam-filling materials pass through the material box 13, rely on the forward driving force of the spiral blade rod 14, and are ejected at the tip of the tapered pipe 12, and finally complete the seam-filling operation.

[0034] The general method of using the grouting pipe device is as follows:

[0035] First, the vertical frame unit 2 is stably placed in front of the vertical wall gap between the tiles to ensure that the tip of the tapered tube 12 can touch the wall gap;

[0036] Second, the positioning ring unit 1 is installed on the tube body 11, and then the positioning ring unit 1 is inserted downward on the vertical frame unit 2;

[0037] Third, adjust the front and rear position of the tube body 11 so that the distance between the tip of the tapered tube 12 and the wall gap is 1-5 mm;

[0038] Fourth, the hand wheel 15 is rotated and the tube body 11 is lowered at the same time to ensure that the tip of the conical tube 12 extrude a continuous seam-filling strip of suitable thickness on the wall gap, and the entire grouting and seam-filling operation is now completed.

[0039] The fixed ring unit 3 and the connecting ring unit 4 are both located in the tube body 11, that is, in direct contact with the seam-filling material. The former has the following functions:

[0040] 1. Limit the spiral blade rod 14 so that it can only rotate in place and cannot move up and down or forward and backward;

[0041] 2. The connecting ring unit 4 is screwed to ensure that there is no leakage between the tube body 11 and the tapered tube 12, and the tapered tube 12 is relatively convenient to disassemble and assemble.

[0042] The positioning ring unit 1 includes a lifting ring 101 sleeved on the outer ring surface of the tube body 11, a limit block 102 arranged on the lifting ring 101 and used to engage the vertical frame unit 2, and an adjustment ring 103 arranged on the outer ring surface of the tube body 11 and used to clamp the lifting ring 101.

[0043] In this embodiment, the lifting ring 101 and the limit block 102 are integrally formed, and the single structure is completely clamped laterally on the vertical frame unit 2 and can only be lifted vertically.

[0044] In addition, the lifting ring 101 and the tube body 11 are only sleeved, not screwed, that is, the front and rear position of the tube body 11 is adjusted by direct pushing, not rotation. This is very important to ensure that the open material box 13 is always open upward to prevent the sealing material inside from falling.

[0045] Finally, after the relative position between the lifting ring 101 and the tube body 11 is adjusted as needed, the adjusting ring 103 clamps the lifting ring 101 to ensure that the relative position is difficult to change spontaneously. In other words, the adjusting ring 103 and the tube body 11 need to be screwed or elastically sleeved with relatively high strength.

[0046] The outer ring surface of the tube body 11 is provided with a thread groove 5 for screwing the adjusting ring 103 ; one adjusting ring 103 is provided on each side of the lifting ring 101 .

[0047] In this embodiment, the thread groove 5 is concave, rather than convex, so as to prevent the lifting ring 101 from scratching the threaded structure on the tube body 11 .

[0048] The adjusting ring 103 may be an internal thread ring or an elastic rubber ring.

[0049] The vertical frame unit 2 includes a bottom plate 201 , two vertical plates 202 disposed on the bottom plate 201 and used to engage the lifting ring 101 , and a vertical sliding groove 203 disposed on opposite sides of the vertical plates 202 and used to insert the limit block 102 .

[0050] In this embodiment, the distance between the two vertical plates 202 is slightly larger than the outer diameter of the lifting ring 101, and lubricating oil and / or balls may be provided in the vertical slide groove 203, thereby ultimately ensuring that the positioning ring unit 1 can be lifted and lowered smoothly and labor-savingly on the vertical frame unit 2.

[0051] The vertical frame unit 2 further includes a top plate 204 disposed on the upper end surfaces of the two vertical plates 202 , and a positioning groove 205 disposed on the lower surface of the top plate 204 and used for engaging the two vertical plates 202 .

[0052] In this embodiment, before the positioning ring unit 1 is disassembled and assembled, the top plate 204 is first removed from the two vertical plates 202. After the positioning ring unit 1 is inserted and installed, the positioning groove 205 is then engaged with the outer contour of the two vertical plates 202 to ensure that the upper end of the vertical plate 202 is not easily deformed to both sides.

[0053] The fixed annular unit 3 includes a fixed rod 301 disposed on the inner annular surface of the tube body 11 , and an external threaded ring 302 disposed on the fixed rod 301 , plugged into the spiral blade rod 14 , and used for screwing the connecting ring unit 4 .

[0054] In this embodiment, the tube body 11, the fixing rod 301 and the external threaded ring 302 are integrally formed, and the external threaded ring 302 is plugged into the central round rod of the spiral blade rod 14 to ensure that the spiral blade rod 14 can stably rotate in situ and push the sealing material forward.

[0055] The connecting ring unit 4 includes a connecting rod 401 disposed on the inner annular surface of the tapered tube 12 , and an internal threaded ring 402 disposed on the connecting rod 401 and used for screwing the external threaded ring 302 .

[0056] In this embodiment, when the inner threaded ring 402 is screwed into the outer threaded ring 302 and the tapered tube 12 fully abuts against the tube body 11 , the inner threaded ring 402 has not yet touched the fixing rod 301 , that is, the fixing rod 301 needs to be appropriately moved back on the outer threaded ring 302 .

[0057] In other words, the length of the thread section of the external thread ring 302 needs to be sufficient.

[0058] A sealing ring 6 is further provided between the tube body 11 and the tapered tube 12 .

[0059] In this embodiment, the sealing ring 6 is a common rubber ring commonly used in the prior art, which is only required to ensure that the sealing material is not likely to leak out between the tube body 11 and the tapered tube 12 .

[0060] The spiral blade rod 14 is also provided with a driving gear 7 .

[0061] In this embodiment, the driving gear 7 and the handwheel 15 are both arranged on the central round rod of the spiral blade rod 14. The function of the driving gear 7 is to expand the use method of the grouting pipe so that the spiral blade rod 14 can not only be rotated by hand, but also can be matched with an external motor for use, ensuring that the grouting operation can be both manual and automated.

[0062] The hand wheel 15 is located between the material box 13 and the driving gear 7 .

[0063] In this embodiment, the driving gear 7 is located at the end to facilitate connection with an external motor, and the size of the handwheel 15 is larger than the driving gear 7, so that when the handwheel 15 is driven by hand, the hand will not be stained with oil on the driving gear 7.

[0064] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
