Description

Technical Field

[0001] The utility model relates to the technical field of building infrastructure, in particular to a structure for high-precision control of expansion joints in large-scale factories. Background Art

[0002] In recent years, with the development of science and technology, the role of artificial intelligence in daily production has gradually become apparent. More and more factories are using machinery to replace manual labor, greatly improving production efficiency. In the past, the expansion joint process in large factories was relatively simple, and the finished products were also used. However, these expansion joints were relatively rough. Although they could be opened by larger mechanical equipment, they would be hindered in the production plants using artificial intelligence systems for more sophisticated equipment, such as AGVs (intelligent robots with high requirements for ground flatness, with a flatness difference of less than 3mm per square meter). Because traditional expansion joints are designed to accommodate uneven building settlement, it is difficult to ensure a flatness difference of less than 3mm per square meter at the expansion joints.

[0003] The main disadvantages of the existing technology include: the high cost of the finished expansion joint and the high labor cost of construction; the slow construction speed of the expansion joint, which consumes time and affects the normal production of the factory; when the factory components expand due to climate temperature changes, the expansion joint structure cannot buffer and reduce their thermal expansion force; when the factory components shrink due to climate temperature changes, the expansion joint structure cannot limit and protect their shrinkage force; the current expansion joints have poor flatness and are not capable of simultaneously passing heavy transport vehicles and high-precision instruments. Utility Model Content

[0004] The purpose of the utility model is to provide a structure for high-precision control of expansion joints in large-scale factories, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a structure for high-precision control of expansion joints in a large-scale factory building, which is provided on a support plate supported by a beam and provided with an expansion joint, comprising:

[0006] A patch plate is provided at the corners of the expansion joint to protect the corners of the expansion joint. The patch plate is also provided with a bearing plate and an anchor plate;

[0007] The bearing plate is used to bear the filling plate, which is used to buffer and protect one side of the expansion joint;

[0008] The anchor plate is provided with a screw rod, and the screw rod is connected to the hanging plate to protect the other side of the expansion joint.

[0009] Preferably, a pad is provided on the supporting plate, and the pad is used to support the filling plate.

[0010] Preferably, caulking glue is filled between the filling plate and the pasting plate to protect the expansion joint.

[0011] Preferably, a water stop is also provided on the bearing plate.

[0012] Preferably, a nut is provided at the connecting end of the screw rod, which is used to fix the hanging plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the structure of the high-precision expansion joint of the large factory building is low in cost because the remaining construction materials on site are used instead of using ready-made expansion joint materials or subcontracting them to expansion joint manufacturers, which saves manpower and material resources, is convenient to construct, has strong operability, is safe and reliable, has good implementation effect, has a strong guiding role in similar projects, has a fast construction speed, can greatly shorten the construction period, and can effectively prevent cracking and deformation of expansion joints. It not only has the ability of traditional expansion joints to buffer the extrusion damage caused by uneven settlement of the factory building, but can also meet the operation of heavy vehicles and high-precision instruments, and these two types of machines are indispensable tools for factory production.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1 、 Figure 3 As shown, the utility model provides a technical solution: a structure for high-precision control of expansion joints in large-scale factories, which is arranged on a bearing plate 10, and a construction steel bar is arranged in the bearing plate 10. After the structure of the expansion joint is set, it is poured. Steel pipes, fasteners and templates are used to support the templates when pouring concrete on both sides of the expansion joint. The material used is C40 fine stone concrete. The bearing plate 10 is supported by a beam 9, and the beam 9 is used to support the bearing plate 10. The material is steel. An expansion joint is provided on the bearing plate 10. The expansion joint is a special structure in the building structure, which is used to solve the volume change and stress caused by factors such as temperature changes and earthquakes. It is also the main structure controlled by this structure, including: a plate 2, which is an angle steel with a size of 60×60×5, preset in the expansion joint in the bearing plate 10, which can be connected to the bearing plate 3 and can also be used as an edge protection angle steel for the expansion joint. It is arranged at the corners of the expansion joint to protect the corners of the expansion joint. A bearing plate 3 and an anchor plate are also provided on the plate 2. 1. The size of the bearing plate 3 is 40×40×5 angle steel, which is used as the embedded angle steel of the expansion joint. The bearing plate 3 is used to carry the filling plate 5. The filling plate 5 is a 20mm thick steel plate, laid between the bearing plates 3, which is used to buffer and protect one side of the expansion joint. A water stop 7 is also provided on the bearing plate 3. The anchor plate 1 is made of HRB400E steel bars, which are used to weld the edge angle steel, that is, the steel bars on the plate 2 and the truss floor decking 10. A screw 13 is provided on the anchor plate 1, and the screw 13 is welded to the anchor plate 1 so that the expansion joint maintains overall stability during deformation. The screw 13 is provided with a thread, which is used to pass through the hanger plate 11 and connect it with the nut 12, so as to fix the hanger plate 11. The screw 13 is connected to the hanger plate 11 to protect the other side of the expansion joint. The connecting end of the screw 13 is provided with a nut 12. The number of screws 13 and nuts 12 is four. Similarly, the hanger plate 11 is provided with four plug holes, which are used to fix the hanger plate 11.

[0024] like Figure 2 As shown, a pad 6 is provided on the bearing plate 3. The material of the pad 6 is a rubber pad 6. There are two pads 6. The pad 6 is used to support the filling plate 5 to ensure that the top of the filling plate 5 and the surface level of the supporting plate 10 are consistent, and to ensure that there is no protrusion that affects the operation of the AGV trolley. The gap filling glue 4 is filled between the filling plate 5 and the pasting plate 2. The gap filling glue 4 is soft glue. When the expansion joint shrinks, the gap filling glue 4 will protect it to achieve a buffering effect, which is used to protect the expansion joint.

[0025] A construction method for a structure of high-precision controlled expansion joints in a large factory building, comprising the following steps:

[0026] When the bearing plate 10 is poured, the cantilever part has been poured. When the cantilever part is chiseled out, the line is laid out in advance, and the electric pick is used to chisel it out after cutting along the line. After chiseling out, the concrete debris is cleaned up;

[0027] After the concrete debris is cleaned, the embedded plate 2 is welded to the anchor plate 1 and the distributed steel bars on the floor deck. The double-sided welding must meet the welding length of ≥5d, and the single-sided welding must meet the welding length of ≥10d. The weld is full and the welding slag is cleaned;

[0028] Tighten the nut 12 on the screw 13, connect the anchor plate 1 and the screw 13 by welding, fix the hanging plate 11 through the nut 12, and fix the hanging plate 11 to the bottom of the expansion joint, so that the expansion joint maintains overall stability during the deformation process;

[0029] After the welding of plate 2 is completed, concrete is poured on the cantilevered part of the expansion joint. When the concrete is poured and the surface is finished, a level ruler is used to control the floor height difference on both sides of the expansion joint to keep the height difference on both sides ≤ 3mm;

[0030] After pouring is completed, when people can walk on it without leaving any traces, the bearing plate 3 and the pasting plate 2 are welded together. The welding operation is standardized, the weld is full and there is no welding slag. At the same time, the angle steel should be kept in a straight line during welding to ensure the laying of the steel plate behind. A water stop 7 is provided on the bearing plate 3 to prevent water leakage.

[0031] After the pad 6 is set and fixed on the bearing plate 3, the filling plate 5 is supported and fixed with caulking glue 4 between the filling plate 5 and the pasting plate 2. The caulking glue 4 is an elastic plastic that can buffer the uneven settlement of the factory building and the damage to the expansion joint caused by the operation of the equipment;

[0032] After the concrete strength at the expansion joint reaches the requirement, the concrete on both sides of the expansion joint steel plate must be polished with a grinder to ensure that there are no protruding areas that affect the operation of the AGV. Use a spirit level to control the height difference of the floor on both sides of the expansion joint while polishing.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
