Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically a continuous sleeve linear positioning tool. Background Technology

[0002] In building construction, pipes passing through floor slabs and shear walls require the installation of sleeves. The accuracy of positioning multiple consecutive sleeves is often not high during construction. In many cases, deviations in the pre-embedded sleeves prevent the later-installed pipes from being centered or result in installation failure due to excessive deviation. Therefore, a method to improve positioning accuracy is needed.

[0003] The current on-site method is as follows: based on the horizontal and longitudinal distances between the center of the lower-level sleeve and the wall column, the center point of the sleeve is found on the upper-level formwork. A screw is driven into the center, and then the position is checked with a plumb line on the lower level using the screw. If the center point of the upper formwork coincides with the center of the lower sleeve, the sleeve can be pre-embedded using this as the center. However, in reality, 1. It is not easy to find the reference line for positioning the wall column on the construction site. Since the upper level has not been poured with concrete, the edge of the formwork can only be used as the reference for the edge of the column. When in the pre-embedding stage, this method of positioning is greatly affected by the accuracy of the civil engineering formwork. 2. Although plumb line positioning can improve the accuracy of the sleeve center positioning, if the quality of the plumb line is poor, elastic, uneven in thickness, or has wear and deformation, it cannot maintain absolute verticality under the action of gravity, resulting in positioning deviation. If the weight of the plumb bob is insufficient, it is difficult to keep the plumb line taut, and it is easily affected by external factors such as wind and swing. 3. This method has many procedures, is cumbersome, and complex procedures are prone to cumulative errors. At the same time, this method requires two people to cooperate between the upper and lower parts of the floor slab.

[0004] Based on the above problems, a positioning scheme is proposed to facilitate the reduction of continuous cumulative errors in the pre-embedding process of continuous sleeves between upper and lower floor slabs. Utility Model Content

[0005] To address the above problems, this utility model provides a continuous sleeve linear positioning tool to solve the problem of accurate positioning and reduce positioning errors when pre-embedding continuous sleeves between upper and lower floor slabs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A continuous sleeve linear positioning tool includes a mounting base, a positioner fixedly mounted on the mounting base, and a positioning device at the bottom of the mounting base for placing the positioner at the center of the pipe.

[0008] The positioning device includes a first support rod and a second support rod that are fixed to each other with the mounting base. Several inner support rods are hinged on the mounting base, and a hinge rod is hinged on the inner support rod. The end of the hinge rod moves along the length direction of the first support rod. The first support rod is provided with a scale to indicate the position of the hinge rod on the first support rod.

[0009] The second support rod is also equipped with a locking mechanism to facilitate its fixation to the pipe.

[0010] As a further improvement to the above technical solution, the first support rod is provided with a guide groove that runs vertically through it, and a slide block that is hinged to the hinge rod is slidably disposed in the guide groove, and a fastener is provided on the slide block.

[0011] As a further improvement to the above technical solution, the locking mechanism includes a baffle fixedly installed on the bottom surface of the second support rod, and the baffle is provided with a locking element that facilitates contact and tightening with the side wall of the pipe.

[0012] As a further improvement to the above technical solution, the first support rod and the second support rod are arranged symmetrically around the center of the mounting base.

[0013] As a further improvement to the above technical solution, each second support rod is provided with multiple baffles of the same number, which are arranged in a ring array around the mounting base.

[0014] As a further improvement to the above technical solution, a level is also fixedly installed on the side of the mounting base.

[0015] As a further improvement to the above technical solution, connecting rings are fixedly provided at the ends of the first support rod and the second support rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. By using a laser linear emission principle to set up a locator on the sleeve, the center point of the pipeline to be reserved can be accurately determined on the top floor slab; by setting up a positioning device, the locator can be accurately positioned at the center of the pipeline on the lower floor slab, thereby ensuring accurate positioning of the reserved pipeline on the upper and lower floor slabs and reducing positioning errors.

[0018] 2. By using the inner support rod, hinge rod, and scale on the first support rod, the positioning device can be quickly aligned with the center of the pipe by adjusting the diameter of the pipe on the lower floor slab. With the interaction of the baffle and locking device, the device can be locked and fixed to the outer wall of the pipe after positioning, thus installing the entire tool on the pipe and preventing positional deviation.

[0019] 3. Use a level to ensure the entire tool is level on the pipe. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the protection scope of this utility model in any way.

[0026] Please see Figure 1-4 In one specific embodiment, a continuous sleeve linear positioning tool includes a mounting base 10, on which a positioner 11 is fixedly mounted. Specifically, in this application, the positioner 11 is a bidirectional laser lamp. The mounting base 10 has mounting holes for the positioner 11, and the bottom of the mounting base 10 has a positioning device for placing the positioner 11 at the center of the pipe. Specifically, the positioning device includes a first support rod 12 and a second support rod 15 fixed to the mounting base 10. Figure 1 As shown, the first support rod 12 pieces and the second support rod 15 are arranged symmetrically around the center of the mounting base 10, and multiple first support rods 12 and second support rods 15 are respectively provided.

[0027] The mounting base 10 is hinged with several inner support rods 13, and each inner support rod 13 is hinged with a hinge rod 14. The end of the hinge rod 14 moves along the length of the first support rod 12. The first support rod 12 is provided with a scale 121 to indicate the position of the hinge rod 14 on the first support rod 12. For details, please refer to the appendix. Figure 3 , 4As shown, the first support rod 12 is provided with a guide groove 122 that runs vertically through it. A slide block 16, which is hinged to the hinge rod 14, is slidably disposed in the guide groove 122. The slide block 16 is provided with a fastener 17, which is a fastening bolt. In actual use, according to the diameter of the pipe pre-installed on the lower floor slab, the slide block 16 is pushed to the corresponding position on the scale 121, which can unfold the inner support rod 13. After all the inner support rods 13 are unfolded, their ends contact the inner wall of the pipe and are adjusted to be horizontal, so that the positioner 11 is exactly in the center of the pipe. By providing the guide groove 122 and the scale 121 on the first support rod 12, the size of the unfolding of the inner support rod 13 can be adjusted to adapt to different pipe diameters, making it applicable to a wider range of applications.

[0028] In this embodiment, to prevent loosening after accurate positioning, a locking mechanism is also provided on the second support rod 15 to facilitate mutual fixation with the pipeline. The locking mechanism includes a baffle 151 fixedly disposed on the bottom surface of the second support rod 15. Specifically, each second support rod 15 is provided with multiple baffles 151, and the number is the same, arranged in a circular array around the mounting base 10, such as... Figure 2 As shown, this allows the baffles 151 on the second support rod 15 at different positions to be within the same circular range. In addition, the baffle 151 is provided with a locking member 18 that facilitates contact and tightening with the side wall of the pipe. In this embodiment, the locking member 18 is a fastening bolt. After the position is accurately positioned, the locking member 18 can be tightened on the baffle 151, thereby fixing the entire tool to the pipe.

[0029] like Figure 1 As shown, in a preferred embodiment, a level 19 is also fixedly provided on the side of the mounting base 10. The level 19 can be used to adjust the horizontal arrangement of the entire tool.

[0030] As a preferred embodiment of the above, the ends of the first support rod 12 and the second support rod 15 are fixedly provided with connecting rings 20, which mainly serve to improve the rigidity of the equipment.
