Description

Technical Field

[0001] The utility model relates to the field of construction equipment, and particularly relates to an adjustable jointing tool. Background Art

[0002] During building construction, there are usually high requirements for progress and quality. Therefore, plaster-free construction is generally adopted for the construction of infill walls. After the wall construction is completed, putty is directly scraped on the wall surface for finishing. Therefore, the forming quality of the mortar joints between the wall masonry blocks directly affects the quality of the finishing layer. In order to make the connection between the upper, lower, left and right masonry blocks more firm, prevent wind and rain from invading the interior of the wall, and make the wall surface clean, neat and beautiful, it is necessary to use mortar to fill the joints to fill the gaps between adjacent two masonry blocks.

[0003] The traditional jointing method is that workers use a putty knife to scrape the horizontal and vertical joints of the wall, or use a round pipe to press. However, this construction method has defects such as non-round joints, non-compact mortar, uneven width and depth of the joints, etc., resulting in easy peeling and cracking of the finishing layer and poor construction quality. With the development of technology, jointing tools dedicated to building construction have emerged. Although to a certain extent, the problems of uneven depth and width of the joints existing in the traditional jointing method have been solved, but since most of the currently used jointing tools are single-operation and cannot be flexibly adjusted according to the needs of the wall, the construction progress is slow and the practicability is not strong. Summary of the Utility Model

[0004] The utility model provides an adjustable jointing tool, aiming to solve the problems of single function and inflexible adjustment of the existing jointing tools, resulting in poor quality of the mortar joints of the masonry blocks and slow construction progress.

[0005] The utility model is an adjustable jointing tool, which includes a cross beam. A handle is arranged at the top of the cross beam, and a plurality of grooves are equidistantly arranged along the length direction at the bottom of the cross beam. A jointing mold is inserted into the grooves.

[0006] Preferably, the groove is a round groove, and an internal thread is arranged in the round groove.

[0007] Preferably, the jointing mold includes a first connecting rod. One end of the first connecting rod is provided with an external thread adapted to the internal thread of the groove, and the other end is detachably connected with a jointing block.

[0008] Preferably, the jointing block is hemispherical.

[0009] Preferably, the jointing mold includes a second connecting rod. One end of the second connecting rod is provided with an external thread adapted to the internal thread of the groove, and the other end is connected with a triangular frame. The bottom of the triangular frame is connected with a third connecting rod, and a jointing ball is arranged at the center of the third connecting rod.

[0010] Preferably, the diameter of the jointing ball is 8-12 mm.

[0011] Preferably, the third connecting rod is cylindrical.

[0012] Preferably, the outer diameter of the caulking ball is greater than the outer diameter of the third connecting rod.

[0013] Preferably, the cross beam is telescopic, and a bolt is inserted into the groove at the middle vacant position for fixation.

[0014] Preferably, an anti-slip sleeve is sleeved on the handle.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. For the caulking tool provided by the present utility model, a caulking die is inserted into the groove at the bottom of the cross beam, which is used to fill the gap between two adjacent masonry blocks of the wall to complete caulking. The caulking die includes a first connecting rod. One end of the first connecting rod is provided with an external thread adapted to the internal thread in the groove of the cross beam, which is convenient for disassembly and assembly. Moreover, the cross beam is telescopic to meet the requirements of different widths of dies needed for caulking different walls. The other end of the first connecting rod is detachably connected with a caulking block, which can be installed and used immediately, occupies a small space, is light in weight, and is practical and convenient.

[0017] 2. The caulking tool provided by the present utility model can also be used for caulking indoor floor tiles. Among them, the caulking die includes a second connecting rod. One end of the second connecting rod is provided with an external thread adapted to the internal thread in the groove of the cross beam, and the other end is connected with a tripod, which increases stability. The top of the tripod is connected with a third connecting rod, and a caulking ball is arranged in the middle of the third connecting rod. Since the gap between floor tiles is small, the diameter of the caulking ball is selected to be 8 - 12 mm, which is flexible and convenient, and the caulking is beautiful. Moreover, both ends of the third connecting rod are in contact with the floor tiles during caulking, which plays a role in shock absorption, avoids sliding and deviating from the tile gap during caulking, and ensures that the caulking is flat and free of burrs.

[0028] The following further describes the present utility model with reference to the accompanying drawings:

[0029] As Figures 1-9 shown, the present utility model is an adjustable jointing tool, including a telescopic cross beam 1. A handle 2 is provided at the top of the cross beam 1, and an anti-slip sleeve is sleeved on the handle 2. Five grooves 3 are equidistantly arranged along the length direction at the bottom of the cross beam 1. The grooves 3 are circular grooves, and internal threads are provided in the circular grooves. A jointing die 4 is inserted into the grooves 3.

[0030] The jointing die 4 has two forms. When used for jointing the exterior wall of a building, the jointing die 4 includes a first connecting rod 5. One end of the first connecting rod 5 is provided with an external thread adapted to the internal thread of the groove 3, and the other end is detachably connected with a hemispherical jointing block 6. When used for jointing the indoor floor tiles, the jointing die 4 includes a second connecting rod 7. One end of the second connecting rod 7 is provided with an external thread adapted to the internal thread of the groove 3, and the other end is connected with a tripod 8. A cylindrical third connecting rod 9 is connected to the bottom of the tripod 8. A jointing ball 10 with a diameter of 8 mm is provided at the center of the third connecting rod 9, and the outer diameter of the jointing ball 10 is 2 mm larger than the outer diameter of the third connecting rod 9.

[0031] Embodiment 1

[0032] As Figures 1-4 shown, when using the jointing tool of the present application to joint the exterior wall of a building, the cross beam 1 is stretched to make the jointing die 4 at its bottom meet the requirement of the mortar joint width between the wall masonry blocks, and then a bolt is inserted into the groove 3 at the middle vacancy for fixation to ensure that the jointing tool does not retract and deform during the jointing process. In this case, three jointing dies 4 are used for operation simultaneously. During jointing, the construction worker holds the handle 2 and puts the three jointing blocks 6 into the mortar joints between the masonry blocks respectively, and then gradually pushes the jointing tool along the length direction of the wall masonry block. During the pushing process, the jointing blocks 6 press the mortar joints to obtain mortar joints with the same roundness, width and depth.

[0033] As Figure 5As shown, since the crossbeam 1 is telescopic, the crossbeam 1 can be extended arbitrarily according to the requirements of exterior wall pointing, and then the pointing mold 4 can be correspondingly installed to meet the needs of different construction scenarios, which is flexible, convenient, highly practical, greatly improves the pointing efficiency, and shortens the construction period.

[0034] Embodiment 2

[0035] As Figures 6-9 shown, when using the pointing tool of the present application for indoor floor tile pointing, the crossbeam 1 is elongated, and the pointing mold 4 is inserted into the groove 3 in the middle of the crossbeam 1. Since the floor tile has a large size and high precision requirements, a single pointing mold 4 is used for this pointing. During pointing, the construction worker holds the handle 2, puts the pointing ball 10 into the joint between the floor tiles, and then gradually pushes the pointing tool 4 along the direction of the floor tiles. During the movement, the pointing ball 10 presses the sealant between the joints to obtain joints that are round, of the same width, and of the same depth.
