Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a long-distance continuous beam-through sleeve positioning device. Background Technology

[0002] Through-beam sleeves are a type of pre-embedded sleeve, which are pipe devices pre-installed during the construction phase of a building structure. They are used to reserve holes for pipes to pass through concrete beams and other components, avoiding damage to the integrity of the reinforcing steel skeleton by opening holes later. They also serve to waterproof and protect the pipes. During construction, through-beam sleeves need to be pre-embedded along with civil construction (such as when tying reinforcing steel bars) and then poured together with the concrete later to ensure a firm bond between the sleeve and the concrete, avoiding problems caused by secondary pouring.

[0003] At present, in the construction process of building engineering, the beam sleeve is usually pre-embedded and mostly high-altitude operation. The working height is usually more than 2.7 meters above the ground. It is usually characterized by long distance and continuous construction, that is, the distance between the starting sleeve and the ending sleeve is usually more than 10 meters. The number of sleeves is generally matched with the number of structural beams, and the interval is generally one every 2 to 3 meters.

[0004] Traditional methods often employ equipment such as laser leveling instruments. During operation, the laser leveling instrument is placed on the ground, and preliminary positioning is completed using a vertical visible laser. A measuring tape is used as an aid. Since the equipment in this method is located on the ground, which is far from the casing construction location, construction errors are prone to occur, causing the continuous casing to not be kept in a straight line, which has a significant impact on subsequent pipeline construction. Based on this, a long-distance continuous beam-penetrating casing positioning device is proposed to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a long-distance continuous beam-through sleeve positioning device to solve the problem that traditional methods often use equipment such as laser leveling instruments. During operation, the laser leveling instrument is placed on the ground, and preliminary positioning is completed with the help of a vertical visible laser. A measuring tape is used as an auxiliary tool. Since the relevant equipment in this method is located on the ground and far away from the sleeve construction position, construction errors are prone to occur, resulting in the continuous sleeves not being kept in a straight line, which has a significant impact on subsequent pipeline construction.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a long-distance continuous beam-penetrating sleeve positioning device, including a sleeve and a laser generator;

[0007] The upper and lower ends of one side of the sleeve are provided with positioning mechanisms for positioning the continuous sleeves in a straight line, and the top and bottom of one side of the sleeve are provided with fixing mechanisms to improve the connection stability between the positioning mechanism and the sleeve.

[0008] The positioning mechanism includes two upper edge fixing plates and two lower edge fixing plates located at the upper and lower ends of one side of the sleeve. The upper edge fixing plates and the lower edge fixing plates are respectively provided with the same left-side clamp and the same right-side clamp on their left and right sides. The top and bottom of the opposite side of the left-side clamp and the right-side clamp are provided with two mortises, and the mortises are respectively connected to the upper edge fixing plates and the lower edge fixing plates by tenon and mortise.

[0009] Through the above technical solutions, the standardized design achieves accurate positioning of the through-beam sleeve, ensuring that the continuous sleeves remain in a straight line, reducing errors in subsequent operations. The modular design improves the applicability of the positioning device, making it suitable for sleeves of different outer diameters. The mortise and tenon joint design between structures greatly improves the reusability of the positioning device and reduces maintenance costs during its service life.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the sleeve is made of galvanized alloy and has a wall thickness of ≥2.5mm.

[0012] Through the above technical solutions, the sleeve made of galvanized alloy material has excellent rust prevention and pressure resistance, which can significantly improve the durability of the sleeve and reduce long-term use costs.

[0013] Furthermore, both upper edge fixing plates and both lower edge fixing plates are made of plastic, and both upper edge fixing plates and both lower edge fixing plates are arc-shaped, with the arc of the side closest to the sleeve being consistent with the arc of one side wall of the sleeve.

[0014] The above technical solution ensures that the two upper edge fixing plates and the two lower edge fixing plates fit snugly against the inner and outer walls of the sleeve, enhancing the stability and assembly accuracy of the positioning structure. At the same time, the use of plastic material reduces weight and cost.

[0015] Furthermore, both the left and right clamps are made of plastic cubes, and the left and right clamps are symmetrically distributed on the left and right sides of the vertical central axis of the upper edge fixing plate.

[0016] By using the above technical solution, the use of plastic material for the left and right clamps can reduce the overall weight and lower production costs.

[0017] Furthermore, through holes are provided in the middle of the upper surface of the two upper edge fixing plates and the two lower edge fixing plates, and the laser generator is located in the through hole provided in the upper edge fixing plate;

[0018] The visible laser beam emitted by the laser generator can pass through the through holes opened on the top lower edge fixing plate, the bottom upper edge fixing plate, and the bottom lower edge fixing plate in sequence.

[0019] The above technical solution enables the visible laser beam emitted by the laser generator to pass through multiple through holes and be emitted to the ground, making it easier for staff to locate and determine the position based on the landing point of the visible laser beam.

[0020] Furthermore, the fixing mechanism includes threaded grooves on the top and bottom of one side of the sleeve, and threaded holes are provided on both the left and right clamps, with a screw threaded into the threaded hole and extending into the threaded groove at one end.

[0021] Both the left and right clamps have oblique grooves on the side facing the sleeve, and oblique blocks are fixed at both the upper and lower ends of the side of the sleeve facing the left and right clamps.

[0022] Through the above technical solution, the fixing mechanism can fix the position of the left and right clamps when the left and right clamps are engaged with the upper and lower fixing plates, thereby preventing separation and avoiding displacement of the laser generator.

[0023] Furthermore, the inclined blocks at the left and right ends are distributed in a mirror image on the left and right sides of the vertical central axis of the sleeve, and the size of the inclined blocks is adapted to the size of the inner cavity of the inclined groove.

[0024] Through the above technical solution, the setting of the inclined block and the inclined groove can locate the position of the left clamp and the right clamp, thereby determining the position of the upper edge fixing plate and the lower edge fixing plate on the sleeve.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0026] 1. The standardized design enables accurate positioning of the through-beam sleeve, ensuring that the continuous sleeves remain in a straight line, reducing errors in subsequent operations. The modular design improves the applicability of the positioning device, making it suitable for sleeves with different outer diameters. The mortise and tenon joint design between structures greatly improves the reusability of the positioning device and reduces maintenance costs during its service life.

[0027] 2. The fixing mechanism can fix the position of the left and right clamps when they are engaged with the upper and lower fixing plates, thus preventing separation and avoiding displacement of the laser generator. The wedge block and wedge groove can position the left and right clamps, thus determining the position of the upper and lower fixing plates on the sleeve. Attached Figure Description

[0037] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0039] Example: Reference Figure 1 A long-distance continuous beam-through sleeve positioning device includes a sleeve 1 and a laser generator 4; both the upper and lower ends of one side of the sleeve 1 are provided with positioning mechanisms 2 for positioning the continuous sleeve 1 in a straight line, and both the top and bottom of one side of the sleeve 1 are provided with fixing mechanisms 3 to improve the connection stability between the positioning mechanism 2 and the sleeve 1.

[0040] Among them, the sleeve 1 is made of galvanized alloy and the wall thickness of the sleeve 1 is ≥2.5mm. The galvanized layer can effectively prevent oxidation and corrosion, extend the service life of the sleeve 1, and the thickened wall improves the pressure resistance and deformation resistance of the sleeve 1, ensuring the reliability of long-term use. At the same time, it takes into account the material strength and corrosion resistance, and reduces maintenance costs.

[0041] refer to Figure 2 and Figure 3 The positioning mechanism 2 includes two upper edge fixing plates 21 and two lower edge fixing plates 22 located at the upper and lower ends of one side of the sleeve 1. The upper edge fixing plates 21 and the lower edge fixing plates 22 are respectively provided with the same left side clamp 23 and the same right side clamp 24. The top and bottom of the opposite side of the left side clamp 23 and the right side clamp 24 are provided with two mortises 25, and the mortises 25 are respectively connected to the upper edge fixing plates 21 and the lower edge fixing plates 22 by tenon and mortise.

[0042] The two upper edge fixing plates 21 and the two lower edge fixing plates 22 are made of plastic. The two upper edge fixing plates 21 and the two lower edge fixing plates 22 are arc-shaped, and the arc of the side near the sleeve 1 is consistent with the arc of one side wall of the sleeve 1. The arc of the two upper edge fixing plates 21 and the two lower edge fixing plates 22 respectively matches the two side walls of the sleeve 1 to achieve a stable connection, while taking into account both lightweight and economy.

[0043] In addition, the left clamp 23 and the right clamp 24 are both plastic cubes, and the left clamp 23 and the right clamp 24 are symmetrically distributed on the left and right sides of the vertical central axis of the upper edge fixing plate 21.

[0044] In this embodiment, through holes 26 are provided in the middle of the upper surfaces of the two upper edge fixing plates 21 and the two lower edge fixing plates 22. The laser generator 4 is located in the through hole 26 on the upper edge fixing plate 21. The visible laser beam emitted by the laser generator 4 can pass through the through holes 26 on the upper edge fixing plate 22, the lower edge fixing plate 21 and the lower edge fixing plate 22 in sequence. The laser generator 4 is a finished laser emitter, and the visible laser beam is a red visible light laser beam.

[0045] Before implementing the long-distance continuous beam sleeve positioning device, the sleeve 1 needs to be cleaned to ensure that the surface is smooth and free of contamination. After cleaning, the top upper edge fixing plate 21 and the top lower edge fixing plate 22 can be placed on the outer and inner side walls of the top of the sleeve 1 respectively to fit together. Then, the left clamp 23 and the right clamp 24 are combined with the left and right sides of the top upper edge fixing plate 21 and the top lower edge fixing plate 22 respectively through the mortise 25. After installation, the middle of the upper edge fixing plate 21 is aligned with the central axis of the sleeve 1. Then, the bottom upper edge fixing plate 21 and the bottom lower edge fixing plate 22 are fixed to the two side walls of the bottom of the sleeve 1 according to the above steps.

[0046] It should be noted that after the overall assembly is completed, the visible laser beam emitted by the laser generator 4 can be emitted to the ground through the through holes 26 opened on the top lower edge fixing plate 22, the bottom upper edge fixing plate 21, and the bottom lower edge fixing plate 22. Construction personnel use the visible laser beam on the ground to measure the landing point and make positioning judgments based on the walls, columns, and measurement and layout marks during the construction process, and make adjustments to ensure accurate positioning. When encountering continuous structural beams, accurate positioning is carried out one by one, and the positioning is constantly checked during the concrete pouring process of the beams and slabs to reduce construction errors.

[0047] refer to Figure 4 and Figure 5 The fixing mechanism 3 includes threaded grooves 31 on the top and bottom of one side of the sleeve 1. Threaded holes 32 are provided on the left clamp 23 and the right clamp 24. A screw 33 with one end passing through and extending into the threaded groove 31 is threaded into the threaded hole 32. Inclined grooves 34 are provided on the side of the left clamp 23 and the right clamp 24 facing the sleeve 1. Inclined blocks 35 are fixed at both the upper and lower ends of the side of the sleeve 1 facing the left clamp 23 and the right clamp 24.

[0048] Among them, the left and right inclined blocks 35 are mirror-distributed on the left and right sides of the vertical central axis of the sleeve 1. The size of the inclined blocks 35 is adapted to the size of the inner cavity of the inclined groove 34, which facilitates the positioning of the upper edge fixing plate 21 and the lower edge fixing plate 22 on the sleeve 1, so that the visible laser beam can pass through multiple through holes 26, ensuring that the continuous sleeve is kept in a straight line.

[0049] When the left clamp 23 and the right clamp 24 are moved closer to the upper edge fixing plate 21 and the lower edge fixing plate 22, the inclined groove 34 on one side of the left clamp 23 and the right clamp 24 slides on the outside of the inclined block 35, thereby limiting the movement of the left clamp 23 and the right clamp 24. After moving to the appropriate position, the screw 33 is aligned with the threaded hole 32, and the screw 33 is screwed into the threaded hole 32 until the other end of the screw 33 enters the threaded groove 31. The left clamp 23 and the right clamp 24 can be fixed to the sleeve 1, ensuring the position of the upper edge fixing plate 21 and the lower edge fixing plate 22, thereby preventing the laser generator 4 from shifting.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
