Description

Technical Field

[0001] The present invention relates to the technical field of assembled steel structures, and in particular to a method and a device for manufacturing an inner partition wall in an assembled steel structure. Background Art

[0002] The partition walls in traditional steel structure houses are all masonry walls. Masonry walls have been eliminated by the market due to their slow construction speed and wet work on site. They have been replaced by prefabricated steel structure interior partition walls. Steel structure walls have gradually been used in steel structure systems due to their light weight, easy installation and fast construction speed.

[0003] The existing connection method between the partition wall and the main body of the steel structure is usually: each wall panel is connected to the steel beam or steel column of the main body of the steel structure through the keel, and the connection between the keel and the steel beam and steel column is welded, bolted, grouting sleeve and grout anchor. The above commonly used connection methods between the keel and the main body of the steel structure building have obvious shortcomings: welding connection causes great pollution to the on-site environment, is difficult to operate, and is easy to cause harm to workers; bolt connection requires pre-opening of steel beams or steel columns, which greatly increases the cost investment, and often leads to difficulties in on-site installation due to insufficient processing accuracy; the grouting sleeve technology is relatively complicated, and the fullness of the sleeve grouting determines the safety quality of the building, but the fullness is difficult to measure; the grout anchor connection requires too many reserved steel bar holes, which makes assembly difficult and inefficient during construction, and requires a long reserved steel bar anchoring length, which makes the production, installation and construction of components difficult.

[0004] However, the current ground construction of gathering and transportation stations is characterized by tight construction period, high environmental protection requirements, and strict cost control. Therefore, how to quickly and cheaply fix and assemble the internal partition walls in the prefabricated steel structure has become a difficult problem that currently bothers us.

[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings provided by the present invention, and the described embodiments are only part of the embodiments of the present invention, rather than 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 work are within the scope of protection of the present invention.

[0040] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects and purposes that can be achieved by the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0041] In order to better understand this solution, the following Figure 1 The manufacturing method of internal partition walls in prefabricated steel structures is introduced in detail.

[0042] 1. One side of the first standardized wall panel is butted against the first steel column in the prefabricated steel structure.

[0043] It should be noted that the fabricated steel structure is a closed steel frame, which includes: an upper steel beam, a lower steel beam, a first steel column, a second steel column, a notch, and a Figure 2 shown.

[0044] Wherein, grooves are respectively arranged on the upper steel beam and the lower steel beam. All standardized wall panels (including the case of the last non-standardized wall panel) enter the closed steel frame through the notch and slide to a suitable position with the help of the notch. Figure 3 shown.

[0045] It should also be noted that the standardized wall panels (including the last non-standardized wall panels) are provided with symmetrical installation grooves at the upper and lower ends, corresponding to the grooves of the upper steel beam, the lower steel beam and the wall. Figure 2 shown.

[0046] It should also be noted that the connection part between the first steel column and the first standardized wall panel is designed as a buckle. Similarly, the connection part between the second steel column and the last standardized wall panel (or the last non-standardized wall panel) is also designed as a buckle.

[0047] Specifically: After the prefabricated steel structure is installed, push the first standardized wall panel along the groove to achieve interlocking docking with the first steel column, and then fix it with bolts and anchors.

[0048] 2. Sewing and reinforcing the Nth standardized wall panel with the previous standardized wall panel in sequence by using nickel-titanium alloy steel wire ropes through the holes, until one side of the last standardized wall panel is sewn and reinforced with the second-to-last standardized wall panel by using nickel-titanium alloy steel wire ropes through the holes.

[0049] Among them, corresponding multiple holes are reserved on the other side of the first standardized wall panel and on one side of the last standardized wall panel (including the case of the last non-standardized wall panel), and corresponding multiple holes are reserved on both sides of other standardized wall panels, while one side of the first standardized module and the other side of the last standardized module (including the case of the last non-standardized wall panel) are only smooth straight edges.

[0050] Specifically: After the standardized wall panels are spliced ​​(or they can be spliced ​​and sewn at the same time), pass the prepared nickel-titanium alloy steel wire rope through the construction tools, pass the nickel-titanium alloy steel wire rope back and forth through the reserved holes, and then sew the two standardized wall panels together like sewing clothes (the nickel-titanium alloy steel wire rope sews the two standardized wall panels horizontally, and then passes through multiple holes from the left side of the wall panel from top to bottom, and then from the right side from bottom to top). After all the holes are passed through, the last reserved nickel-titanium alloy steel wire rope is fixed using the wedge sleeve fixing method. That is, one end of the nickel-titanium alloy steel wire rope is passed around a special inclined wedge, and the locking effect of the wedge in the sleeve is used to fix the nickel-titanium alloy steel wire rope. In order to have better stability, it is fixed again by pouring concrete between two adjacent standardized wall panels, such as Figure 4 shown.

[0051] It should also be noted that the present invention does not require rivet anchors, but uses a new type of nickel-titanium alloy wire rope. Nickel-titanium alloy is a shape memory alloy, which is a special alloy that can automatically restore its own plastic deformation to its original shape at a certain temperature. Its expansion rate is above 20%, and its damping characteristics are 10 times higher than ordinary springs. Its corrosion resistance is better than the best medical stainless steel currently available, so it can meet the application requirements of various projects and is a functional material. In addition to its unique shape memory function, shape memory alloys also have the advantages of wear resistance, corrosion resistance, high damping and superelasticity.

[0052] The preparation method of nickel-titanium alloy wire rope is as follows: the raw material nickel-titanium alloy is made into steel wire of specified diameter and hardness through heating and stretching processes; according to the design holes reserved in the partition wall of the assembled steel structure and the use conditions, multiple strands of steel wire are wound according to specific specifications, lengths and tensions to form a wire rope; the length of the wire rope is cut as needed and the end is positioned, welded, marked and burred to make a memory metal thin steel rope that meets the design requirements and use conditions. The preparation of wire rope by multiple strands of steel wire is specifically as follows: each strand of steel wire is twisted twice to form a strand, and the adjacent strands are twisted and braided for a second time to make the wire rope stronger and more durable.

[0053] 3. The other side of the last standardized wall panel is butted against the second steel column in the prefabricated steel structure.

[0054] The other side of the last standardized wall panel is interlocked with the second steel column in the prefabricated steel structure and fixed with bolts and anchors.

[0055] Specifically, when installing wall panels, the following two situations may occur: (1) For the case where the wall length is an integer multiple of the standardized wall panels, after the first standardized wall panel is interlocked with the first steel column, the second standardized wall panel is also sewn and fixed along the groove to the first standardized wall panel, and then connected in sequence. When installing the last standardized wall panel, because the other side of the last standardized wall panel also needs to be interlocked with the second steel column, it is necessary to design it as a foldable wall panel (that is, multiple foldable node components are set in the middle of the wall panel, and the number can be flexibly set according to demand), and install it in a folding and pushing manner to achieve rapid docking of standardized wall panels, and finally perform edge sealing on all sides of the wall panel. Specifically: the fastener base plate is fixed to both sides of the broken part of the wall panel to be folded by bolts, and the panel is fixed to the base plate by bolts at the sliding bolt holes. After the wall panel is installed, the fasteners are removed, such as Figure 5 and 6 shown.

[0056] (2) If the wall length cannot meet the integer multiple of the standardized module, after the first standardized wall panel is interlocked with the first steel column, the second standardized wall panel is also sewn and fixed along the groove to the first standardized wall panel, and then connected in sequence. When installing the last non-standardized wall panel, because the other side of the last non-standardized wall panel also needs to be interlocked with the second steel column, it can be designed as a foldable wall panel (that is, a foldable node component is set in the center of the remaining length of the wall panel), and installed in a folding and pushing manner to achieve rapid docking of the wall panels, and finally the wall panels are edge-sealed on all sides.

[0057] It should also be noted that in order to make the steel structure building have the functions of thermal insulation, sound absorption and noise reduction, and safety protection, the present invention fills glass fiber wool between the first standardized wall panel and the first steel column, between the last standardized wall panel and the second steel column, between the standardized wall panel and the upper steel beam and the lower steel beam, and between the standardized wall panels.

[0058] Glass fiber wool is a cotton-like material made by fiberizing molten glass. Its chemical composition belongs to glass and it is an inorganic fiber. It has the characteristics of A1 fireproof, low volume density, high thermal conductivity, thermal insulation, good sound absorption, corrosion resistance, and stable chemical properties. The fibers inside the glass fiber wool are fluffy and interlaced, and there are a large number of tiny pores. It is a typical porous sound-absorbing material with good sound absorption characteristics. When sound waves are incident on centrifugal glass wool, the sound waves can enter the material through the pores, causing the air molecules in the gaps to vibrate. Due to the viscous resistance of the air and the friction between the air molecules and the pore walls, the sound energy is converted into heat energy and lost. Centrifugal glass fiber wool can be made into wall panels, ceilings, space sound absorbers, etc., which can absorb a large amount of sound energy in the room, reduce the reverberation time, and reduce indoor noise.

[0059] The present invention also provides a device for making an inner partition wall in a prefabricated steel structure, wherein the inner partition wall includes a plurality of standardized wall panels provided with holes, and the device includes: an interlocking unit, used to interlock and dock one side of a first standardized wall panel with a first steel column in the prefabricated steel structure; a suturing unit, used to sequentially sew and reinforce the Nth standardized wall panel with the previous standardized wall panel using nickel-titanium alloy steel wire ropes through the holes, until one side of the last standardized wall panel is sewed and reinforced with the second-to-last standardized wall panel using nickel-titanium alloy steel wire ropes through the holes; and a docking unit, used to interlock and dock the other side of the last standardized wall panel with the second steel column in the prefabricated steel structure.

[0060] Since the content protected by this device corresponds to the content protected by the above method, no further introduction is given here. Please refer to the description of the method for details.

[0061] The present invention is a method for quickly fixing wall panels by sewing. Standardized wall panels are used, and holes are reserved on one wall panel, and matching holes are also reserved on another wall panel, so that the prefabricated wall panels are sewn together, so that the application range is wider, the speed is faster, and the efficiency is higher during assembly (it only needs to reserve holes on the wall panels in advance, and directly use steel ropes to connect on site, without the need for rivets, anchor bolts and other construction activities), and the number of standardized wall panels can be changed to meet the needs of closed steel frames of different sizes, which is more flexible to use. At the same time, the connection structure is conducive to energy consumption and shock absorption. Moreover, the standardized wall panels enter the closed steel frame through the gap, and slide to a suitable position with the help of the notch, which is convenient to operate, simple in structure, high in assembly efficiency, fast in construction speed, and the gap is closed by a fixed plate, without the need for punching and connection, so the structure is firm and stable, the construction cost is low, and it has good economic benefits.

[0062] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
