Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building construction, concretely relates to a calibrator for pre -buried part installation construction. BACKGROUND

[0002] In the process of industrial plant construction, a large number of process equipment needs to be installed in the plant, so steel pre-buried parts are usually pre-buried on the equipment foundation for later equipment installation. The so-called millimeter error affects thousands of miles, the plane positioning and elevation control of pre-buried part installation directly affect whether the process equipment can be successfully installed and function, and the importance of pre-buried part installation precision control is self-evident.

[0003] Through consulting technical literature, consulting technical patents, interviewing senior management personnel in the construction industry and other ways, it is understood that the existing technology for pre-buried part installation is as follows: first, use a measuring instrument to lay out and position the plane position of the pre-buried part, then use chalk, paint and other tools with scribbling function to mark the position, then place the pre-buried part at the marked position (usually on the equipment foundation reinforcement), then slowly insert wooden or iron wedges around the edge of the pre-buried part, since the contact surface of the wedge and the pre-buried part is inclined, the pre-buried part elevation can be adjusted by pushing or pulling out the wedge. Finally, repeatedly adjust the pushing and pulling out of the wedge, repeatedly measure the elevation of the pre-buried part, until the elevation of the pre-buried part meets the design drawing requirements. Finally, pour commercial concrete under the pre-buried part, so as to realize the purpose of integrating the pre-buried part with the concrete pouring, and provide a prerequisite for subsequent equipment installation.

[0004] The existing pre-buried part installation process mainly has the following shortcomings:

[0005] (1) Limited applicability, since the existing pre-buried part installation process adjusts the elevation by the gravity of the pre-buried part itself in cooperation with the wedge, the stress point at the bottom of the wedge is the reinforcement, and this form of stress is only suitable for equipment foundation with small area and no other load, if the equipment foundation area is large and needs to bear other loads (such as the weight of construction workers), the installed pre-buried part will rebound upward due to the deflection of the reinforcement after the workers leave, which will cause the pre-buried part to be too high.

[0006] (2) Slow installation progress, since the existing pre-buried part installation process positions the plane of the pre-buried part by measuring instrument positioning and laying out, only one pre-buried part can be positioned at a time, which is low in efficiency. Secondly, the existing pre-buried part installation process adjusts the elevation by repeatedly pushing or pulling out the wedge, so there is a phenomenon of repeated adjustment and repeated measurement of the elevation during elevation adjustment, which leads to slow pre-buried part installation progress.

[0007] (3) high installation cost, since the pre-embedded part installation is completely implemented by manual work, the installation cost of all pre-embedded parts is determined by manual work, in other words, the installation cost is higher if the installation progress is slow.

[0008] (4) elevation control is difficult to achieve millimeter level, since the existing pre-embedded part installation process has the problems of repeated advancement, displacement amount cannot be accurately controlled when the wedge is pulled out, and the pre-embedded part fixing steel is greatly affected by external force, the pre-embedded part installation elevation control is almost impossible to achieve millimeter level precision requirement.

[0009] In addition, since the pre-embedded part installation is only a small part of the work content in a single building, and the installation process is mainly leveled and installed by welders, the pre-embedded part installation process has been stagnant. If the number of pre-embedded parts of the project is not large and the precision requirement is not high (more than 1 cm), the existing pre-embedded part installation process in the industry can also achieve the functional requirements. However, due to the replacement of process equipment technology and the increasingly stringent relevant specifications, the precision requirement of pre-embedded part installation is different. The current standards and requirements are often in millimeter units for plane positioning and elevation control. If the existing pre-embedded part installation process in the industry is used, this precision requirement is often not required. The number of pre-embedded parts of industrial plants is large, and if the existing pre-embedded part installation process in the industry is used, the installation quality, installation progress, and installation cost cannot meet the project management requirements. Practical new type content

[0010] In view of the above-mentioned deficiencies in the prior art, the calibrator for pre-embedded part installation construction provided by the present application solves the problems of slow progress and difficult elevation control of the existing pre-embedded part installation process.

[0017] Further, the locating rod is an angle steel, and a scale is arranged on the angle steel.

[0018] The technical effect of the above further scheme is that the cross section of the angle steel is L-shaped, one side of which is horizontal and the other side is vertical. The vertical side is convenient for fixing with the threaded sleeve, and the horizontal side is convenient for detachable fixing with the embedded part. The angle steel is a commonly used material in factory construction, so that the calibrator can be made on site, is flexible to use, and has strong bending resistance, which helps the positioning of the embedded part. The scale is convenient for construction personnel to obtain and adjust the distance between the embedded parts fixed on the same locating rod, improving the efficiency and precision of embedded part construction.

[0019] Further, the fixer is a vice.

[0020] The technical effect of the above further scheme is that the vice can clamp materials of different thicknesses, and is convenient and easy to obtain.

[0021] Further, the other end of the threaded rod is provided with a flat washer.

[0023] Further, the threaded sleeves on the same locating rod are arranged in parallel, and the included angle between the locating rod and the threaded sleeves thereon is 90°.

[0024] Further, the thread height of the thread adopted by the threaded sleeve and the threaded rod is 1mm.

[0025] The technical effect of the above further scheme is that the adjustment height of the threaded rod is the adjustment height of the embedded part, which can greatly improve the embedded part height adjustment precision and realize accurate high mark control.

[0026] Further, the two locating rods for fixing the same group of embedded parts are arranged in parallel.

[0027] The technical effect of the above further scheme is that the two locating rods arranged in parallel can simultaneously position and calibrate multiple embedded parts of the same size, improving the construction efficiency.

[0028] Further, the threaded sleeve is fixedly arranged with the locating rod by welding.

[0029] The technical effect of the further scheme is that the whole calibrator is rigidly connected, has strong bearing capacity and is convenient to produce.

[0030] Further, the positioning rod is welded with a vertical hollow pipe column, the horizontal bolt is arranged on the hollow pipe column, the hollow pipe column is sleeved outside the threaded sleeve, and the relative displacement of the threaded sleeve and the hollow pipe column is limited by adjusting the horizontal bolt to extrude the threaded sleeve.

[0031] The technical effect of the further scheme is that the height of the positioning rod from the ground can be quickly adjusted by adjusting the height of the threaded sleeve in the hollow pipe column, and the threaded sleeve, the threaded rod, the handle and the positioning rod can be stored and transported separately; the threaded sleeve cannot slide in the hollow pipe column by extruding the threaded sleeve by the bolt, thereby ensuring the stability of the calibrator during use.

[0032] Further, the leveling instrument is arranged on the positioning rod.

[0033] The technical effect of the further scheme is that the construction personnel can easily know the level data of the current embedded part position. BRIEF DESCRIPTION OF DRAWINGS

[0039] The specific embodiments of the utility model are described below, so that the technical personnel in the technical field can understand the utility model, but it should be clear that the utility model is not limited to the scope of the specific embodiments, and for the ordinary technical personnel in the technical field, as long as various changes are within the spirit and scope of the utility model defined and determined by the appended claims, these changes are obvious, and all the inventions and creations using the concept of the utility model are within the scope of protection.

[0040] For example, Figure 1 And Figure 2As shown, the calibrator for embedded part installation construction includes two fixers 8 and two positioning rods 1;

[0041] The same embedded part 6 is detachably fixed with the two positioning rods 1 through the two fixers 8 respectively;

[0042] At least two threaded sleeves 2 are arranged on each positioning rod 1; and a threaded rod 3 matched with the threaded sleeve 2 is arranged in each of the at least two threaded sleeves 2 on the same positioning rod 1.

[0043] The threaded rod 3 is provided with a handle 4 at an end higher than the positioning rod 1, and the height of the threaded sleeve 2 and the positioning rod 1 relative to the ground is adjusted by rotating the handle 4, so as to adjust the height of the embedded part 6 relative to the ground.

[0044] In the embodiment, in order to make the positioning rod 1 of the calibrator be made on site and ensure the bending resistance, the positioning rod 1 adopts a 40*40 angle steel. In order to facilitate the construction personnel to obtain and adjust the distance between the embedded parts 6 fixed on the same positioning rod 1, and improve the efficiency and precision of the embedded part construction, the angle steel is provided with a scale.

[0045] In order to enable the fixer 1 to clamp different thicknesses of materials, and to be convenient, easy to obtain and use, the fixer 1 adopts a vise. It should be noted that, in addition to the vise, other hydraulic locking, electric locking devices can also be used as the fixer 1.

[0046] In order to increase the contact area of the threaded rod 3 with the ground and improve the stability of the calibrator, the other end of the threaded rod 3 is provided with a flat washer 5.

[0047] The threaded sleeves 2 on the same positioning rod 1 are arranged in parallel, and the included angle between the positioning rod 1 and the threaded sleeves 2 thereon is 90°. The thread height of the threaded sleeve 2 and the thread adopted by the threaded rod 3 is 1mm (i.e. rotating the handle 4 by one turn can adjust the height by 1mm), and rotating the handle 4 by one turn in the forward or reverse direction can realize lifting or lowering the embedded part 6 by 1mm. Similarly, rotating the handle 4 by 0.5 turn in the forward or reverse direction can realize lifting or lowering the embedded part 6 by 0.5mm, so as to realize the millimeter level precision requirement. In addition, the thread with 0.01mm / silk can be produced in the industry at present, and after the calibrator is replaced with the thread, the embedded part 6 can be lifted or lowered by 0.01mm by rotating the handle 4 by one turn in the forward or reverse direction, the embedded part 6 can be lifted or lowered by 0.005mm by rotating the handle 4 by 0.5 turn in the forward or reverse direction, and so on.

[0048] In order to enable the two positioning rods 1 to simultaneously position and calibrate multiple embedded parts 6 of the same size, and improve the construction efficiency, the two positioning rods 1 for fixing the same group of embedded parts 6 are arranged in parallel in the embodiment.

[0049] In one feasible example of this utility model, the threaded sleeve 2 is directly welded to the positioning rod 1. Its advantages are that the entire calibrator is rigidly connected, has strong load-bearing capacity, and is easy to manufacture; the threaded sleeve 2 can also be made relatively short (within 5 cm). The disadvantages are that the height of the calibrator can only be adjusted by rotating the handle 4 or by placing an object under the threaded rod 3, which is not conducive to a wide range of height adjustments and also makes storage of the calibrator difficult.

[0050] In one feasible embodiment of this utility model, a vertical hollow tube 9 is welded onto the positioning rod 1, such as... Figure 3 As shown, the hollow tube column 9 has a transverse threaded hole, and a matching bolt 10 is installed in the threaded hole. The bolt 10 can be rotated to enter the interior of the hollow tube column 9 and compress its internal space. The hollow tube column 9 is fitted over the threaded sleeve 2. When the bolt 10 is not compressing the internal space of the hollow tube column 9, the threaded sleeve 2 can move up and down relative to the hollow tube column 9. When the bolt 10 compresses the internal space of the hollow tube column 9, the bolt 10, together with the hollow tube column 9, clamps the threaded sleeve 2, thus fixing the threaded sleeve 2 relative to the hollow tube column 9. This method allows for a wide range of adjustment of the height of the positioning rod 1 relative to the ground, and fine-tuning can be performed by rotating the threaded rod 3, enabling quick and precise adjustment of the orientation of the embedded part 6. Furthermore, in this method, the length of the hollow tube column 9 can be controlled within 10 cm, and the threaded sleeve 2 can be decoupled from the positioning rod 1 for storage, reducing volume and facilitating storage, transportation, and handling. The disadvantage of this method is that in order to ensure the height adjustment range of the threaded sleeve 2, the length of the threaded sleeve 2 needs to be relatively long (the length of the threaded sleeve 2 is set according to actual needs).

[0051] In one embodiment of this utility model, a level is installed on the positioning rod 1 to facilitate construction personnel in understanding the horizontal data of the current position of the embedded part 6. Construction personnel can quickly determine whether the embedded part 6 has been placed in place using the level.

[0052] In the specific implementation process, the civil engineering construction unit will complete the binding of the main structural steel bars at the six locations where the embedded parts are to be installed, according to the design drawings, to meet the conditions for pouring concrete. For example... Figure 4 As shown, the embedded part 6 to be installed is then transported to the installation position, and the embedded part 6 is firmly assembled with the positioning rod 1 using pliers. The height and position of the embedded part 6 are adjusted by adjusting the height of the threaded sleeve 2 and / or the height and position of the threaded rod 3 until the top of the embedded part 6 is adjusted to the design elevation. Then, the handle 4 is fixed, thus completing the elevation adjustment of the embedded part 6.

[0053] After the elevation adjustment is completed, the embedded part 6 is welded and fixed to the stable steel mesh using steel reinforcement 7. Then, the calibrator is removed, and finally concrete is poured to complete the installation of the embedded part 6.

[0054] During the whole use of the present calibrator, the stress points of the embedded part 6 are transmitted to the present calibrator through the big force clamp, and the stress points of the present calibrator are transmitted to the ground through the threaded rod 3, so the embedded part 6 and the present calibrator form an independent stress system, which is no longer affected by other loads in the construction process, and can be widely used for the installation and construction of embedded parts 6 in various environments and working conditions.

[0055] The angle steel of the present calibrator can simultaneously fix multiple embedded parts 6, and only needs to adjust the angle steel when adjusting and positioning, so that the embedded parts 6 are adjusted once and linked to achieve the result of adjusting the angle steel, and the angle steel adjustment is realized by rotating the handle 4 to adjust the threaded rod 3, which is a linear adjustment mode, and often only needs to be adjusted once without repeated adjustment. Due to the above two reasons, the construction efficiency of the present calibrator for embedded part 6 construction can be doubled compared with the original construction method.

[0056] Through the analysis of the embedded part installation sub-item of a certain intelligent packaging project: the project has a total of more than 22,000 embedded parts, and a total of about 9170 workdays (1 workday is 8 hours), and the work efficiency is 2.4 pieces / workday. In the intelligent packaging project, the present calibrator is used for embedded part installation, a total of 34,630 embedded parts are installed, a total of about 7126 workdays (1 workday is 8 hours), and the work efficiency is 4.9 pieces / workday. As can be seen, the construction efficiency of the present calibrator for embedded part construction can be improved by 204.4% compared with the existing embedded part installation method in the industry, and the installation progress can be doubled.

[0057] Regarding the installation cost - since there is no fixed unit price for embedded part installation, and the number and specifications of embedded parts in each engineering project are not the same, the embedded part installation unit price is generally determined by the measured work efficiency. For example, the technical worker's wage level in a certain area in 2024 is 232 yuan / workday, then the construction unit price of the existing embedded part installation method in the industry is: 232 yuan / workday ÷ 2.4 pieces / workday = 96.7 yuan / piece, and the construction unit price of the present calibrator is: 232 yuan / workday ÷ 4.9 pieces / workday = 47.3 yuan / piece, and the construction cost is also saved by 204.4%.

[0058] In summary, the present calibrator has the advantages of millimeter-level control and can be extended to 1 / 1000 millimeter level in precision control compared with the existing embedded part installation method in the industry. At the same time, the construction efficiency and construction cost have also been greatly optimized.
