Description

Double-hook manual docking steel frame

technical field

The double-hook manual butt steel frame technology involves the steel frame, which refers to the steel structure components such as steel pipes and connecting blocks of the steel frame. The "double-hook butt joint" is used to connect all the components manually to complete large, medium and small. It is named for the steel skeletons of various sports venues, buildings, buildings, tower cranes, gantry cranes, row cranes, and various bridge steel columns and beams.

Background technique

I agree with what Tsinghua University Institute of Architecture recognizes. Our housing has gone through three eras: "thatched house", "brick house" and "elevator house"; but the institute's "fourth generation housing" "The concept gave me a great inspiration. If there is a new type of construction technology support, coupled with the country's strong support, this new concept will definitely be realized.

The "Three-piece Butt Butt" ZL200820192513.7, "Double Hook Butt" ZL200820192512.2, and the "Three-piece Butt Butt Formwork", "Three-piece Butt Butt Scaffold" and "Double Hook Butt Butt Scaffold" that I designed The patent numbers are ZL200920227956.X, ZL200920227957.4 and ZL200920227958.9, and they have obtained national patents. This is my summary in the construction industry for so many years; it introduces the innovation of turnover materials that must be used in construction. When companies recommend these technologies, they are opposed by many companies. The reason is very simple, "The construction turnover materials produced according to this technology will increase the cost of turnover materials, and the use of this kind of high-precision turnover materials is - anti-aircraft guns to fight mosquitoes. ——Great talent, small use"; I have found many tower crane manufacturers, and I have also been to the steel structure construction unit that participated in the Beijing Bird's Nest, and to several large steel structure enterprises in Hangzhou. I recommended and introduced these scaffolds with many technicians and company bosses They all think that "this is an industry revolution in the steel structure industry and the tower crane industry!" And the name "scaffolding" of such a technology is called - a big head with a small official hat - not worthy of the name, It is difficult to promote in this industry with such a patent name, and it must be repackaged.

The double-hook manual butt steel skeleton technology includes both ends of the steel pipe and the well-shaped, single-pipe, and spherical connection block joints. The corresponding double-hook joints have the same form and size. After seaming into a round rod, the casing is completely locked. It is not a simple or repeated "double-hook butt-joint scaffold" technology, but a development and sublimation of its technology. Compared with the "double-hook butt-joint scaffold" technology, it will be better. Because of its technology: First, each force point is reinforced in its technology, that is: the double hook joint and the double hook joint on the docking point, the structure form and size standard of the two double hooks are exactly the same, and the two double hooks are closed. Finally, it is completely seamed into a round rod shape, the inner circle of the casing is the same as the diameter of the outer circle of the round rod, and the casing is completely locked in the round rod-shaped double hooks; the second is that the original connecting block is a well-shaped and cross-shaped connecting block, which is now increased to a well-shaped , single tube, sphere connection block, at the same time, the number, direction, and angle of the force point of the well shape, single tube, and sphere connection block should be firmly welded according to the needs of the skeleton; When disassembling, it is installed and disassembled layer by layer from top to bottom. This technology adds a single-insert double-hook joint and a double-hook rotary joint in one side of the steel pipe. The owner wishes to increase rooms or walls, and increase or decrease rooms and walls at any time, do it at will, especially the addition of a double-hook swivel joint in the steel pipe, which can also be welded on the corresponding joint. After having a rotating double-hook joint , does not reduce the strength of the steel pipe, and it is not necessary to consider the direction of the welding double hook during production and processing, and it can be installed manually, which is convenient and reliable. Whether it is a mountain or a plain, whether it is a city or a country, whether it is the ground or the water, and the construction floor and area can be high or low, large or small.

Contents of the invention

The double-hook manual butt steel skeleton technology is used in the "fourth generation housing" as the skeleton of this generation of housing: first, the entire construction project must be redesigned and must be approved by the architectural design institute; second, the production and construction parties do not need to Any mechanical equipment can be installed manually, and the hoisting equipment of the three-dimensional construction on the construction site is integrated with the house skeleton, and the hoisting equipment is installed while the steel structure housing skeleton is raised. After the skeleton is installed, the house is completed as a whole; third, Carry out the overall house decoration and partial decoration directly on the house skeleton to complete the housing function; Fourth, the housing materials completely abandon reinforced concrete, and also widely use the building materials, such as furniture, wardrobes, etc., to decorate the walls and so on. Such a building form will completely change the concept of building construction, completely change the building construction plan, completely change the building construction materials, completely change the building construction technology, and thus completely subvert the entire construction industry. The application of this technology will completely bid farewell to the "reinforced concrete" Elevator Room Era".

The double-hook manual butt steel skeleton technology can also be applied to the steel skeletons of large, medium and small stadiums and halls, various tower cranes, gantry cranes, row cranes, and various bridge steel columns and beams. On the shelf, the entire construction process is the same as that of housing construction: first, the entire construction project must be redesigned and must be approved by the architectural design institute; The hoisting equipment of the three-dimensional construction is integrated with the skeleton, and the hoisting equipment is installed while the steel skeleton is raised. After the skeleton is installed, the overall installation is completed; the third is to carry out overall decoration of the internal facilities, such as stadiums and halls And segment decoration fulfills its function and so on.

The double-hook manual butt steel frame technology mainly consists of steel pipes and well-shaped, single-pipe, and sphere connection blocks. The two ends of the steel pipes are double-hook joints; It is also a double-hook joint. According to the needs, these connecting blocks are connected with steel pipes to form various steel frameworks. Taking the tower crane as an example, the main body of the tower crane column is composed of steel pipes and well-shaped connecting blocks; the beam of the tower crane is composed of steel pipes and spherical connecting blocks, each of which constitutes the cubic and triangular steel framework required by the tower crane. The main body of the tower hanging column and the beam of the tower crane, which use the triangular firmness characteristics, divide each shape into a triangular structure and connect them; these connected force points are the double hook joints of various connecting blocks. According to the requirements of the structural skeleton, the double-hook joints are welded at regular distribution angles. After the sphere connection blocks of the double-hook joints are welded on the distribution angles and the steel pipe double-hook joints are docked, each shape is divided into triangles and connected in the form of a whole. The cubic plate becomes a three-dimensional mechanical steel framework with incomparable strength and power.

The various parts of the double-hook manual butt joint steel frame technology are completed by professional manufacturers in the workshop. Using CNC machine tools, washing beds and special modules, automatic welding machines and manipulators are completed on the production line to ensure the precision of pipes and blocks. Manufactured to ensure that the steel frame is firm and reliable, and the mechanical strength of on-site welding is not weak at all; at the same time, various processes can be used to ensure the external rust prevention measures of each pipe block during processing in the workshop, so that after manual docking, the installation and forming can be completed in one step. It not only reduces the labor intensity of workers, but also speeds up the progress of the project; each pipe and block component has its own stamped banner composed of English letters and Arabic numerals, including specifications, materials, wall thickness, seamlessness, bearing tonnage, supervision The national and international standards for the main contents of the steel frame, such as unit, manufacturer, batch and date of manufacture, enable workers to connect the pipe block components in place as soon as they get them.

Double-hook manual butt steel skeleton technology and "three-piece manual butt steel skeleton", "single-hook manual butt steel skeleton", "two-type manual butt steel skeleton", "manual butt steel skeleton" technology The utility model patents of the National Patent Office were reported on January 11, March 11, March 25, and April 4, 2019 respectively. The patent numbers are 2019203111629.6 and 201920050697.1, 201920457410.7, 201920457388.6, and 201920311629.6. Butt jointer", "single hook butt joint" and "double hook butt joint" technology, connect all the components, and complete the large, medium and small various stadiums, halls, building steel skeletons and various Tower cranes, gantry cranes, row cranes, and various types of bridge steel columns, beam frames and other steel skeletons; in today's construction industry, the frame of a building with more than 100 floors, considering the structure of reinforced concrete, its weight cannot be the same as that of the ground floor and The foundation is generally supported by a steel frame; and the reason why these technologies I introduced can replace the on-site welding form has their theoretical roots: the "three-piece set", "double hook" and "single hook" I introduced are It means that these force-bearing contact surfaces exceed the cross-sectional area of the steel pipe wall, that is to say, the cross-sectional area of the steel pipe wall is smaller than the cross-sectional area of the same round rod, and it is also less than 1/4 of the same round rod cross-sectional area. "Double hook" and "single hook" are made of the same garden rod, and the cross-sectional area of each part is 1/3. Therefore, it is far larger than the cross-sectional area of the steel pipe wall. This is the first; "Piece set", "single hook" and "double hook" are all made of high carbon steel, which is unmatched by all steel pipe materials; thirdly, the steel pipe sheath is cleverly used, which not only protects the connection point but also facilitates loading and unloading , so that all the added force can only be done along the sheath of the steel pipe. Therefore, these manually-joined steel skeletons are theoretically superior to the mechanical strength of on-site welding, thus ensuring the function of building houses; three-piece manual Butt steel frame technology is the same as "Single-hook Manual Butt Steel Frame" and "Double-Hook Manual Butt Steel Frame", "Manual Butt Steel Frame" and "Two-type Manual Butt Steel Frame". Large, unique craftsmanship, unique design, precise production, simple construction, and convenient decoration are all rare masterpieces in the history of architecture.

The application of double-hook manual butt joint steel frame technology will achieve "four provinces", namely: construction period saving, construction material saving, construction equipment saving, and labor saving; at the same time, it will achieve "four excellent", namely: construction Excellent quality, excellent project accuracy, solid skeleton, and excellent service life; take the Beijing Bird's Nest as an example: the Bird's Nest started construction on December 24, 2003 and was completed in March 2008. If the double-hook type manual butt joint steel frame technology is used to construct Beijing's Bird's Nest project, it will save a lot of welding projects on site, save a lot of manpower, financial resources, and material resources, and also save engineering time. From estimating manpower and financial Various costs such as equipment, machinery and equipment only account for 10%, and it also saves engineering time, and it may only take one year to complete.

detailed description

The double-hook manual butt joint steel frame technology mainly consists of steel pipe 1, well-shaped connecting block 2, single-pipe connecting block 3, and sphere connecting block 4. Both ends of the steel pipe are double-hook joints 5; Corresponding to the double-hook joint of the steel pipe head is the double-hook joint; two double-hooks and a sleeve, known as "double-hook butt joint", the structural form and size standard of the two double-hooks are exactly the same, and the top is two relatively semicircular Double hooks, in the middle is a semi-circular square rod connected with a round rod. After the two double hooks are closed, they are completely sewn into a round rod. The inner circle of the sleeve 6 is the same diameter as the outer circle of the round rod, and the sleeve is completely locked. In the shape of a round rod, there is a threaded button 7 at the bottom of the double hook of each force point of each well-shaped, single-tube, and sphere connection block, corresponding to the inner threaded button 8 at the casing end, for fixing the casing, and there are gongs at both ends of the steel pipe The screw 9 is another form of the fixed casing, and the two methods can be used singly or simultaneously; the spheroid connection block and the steel pipe are the core of the steel structure skeleton, therefore, the welding changes of a plurality of double hook joints on the spheroid connection block, There are 45°, 60°, and 90° layouts on the whole or half surface, which are designed according to the needs of the skeleton, and also determine the shape of the steel skeleton structure; the specifications of the steel pipes, the connection blocks such as well shapes, single pipes, and spheres are all combined The shape summarized in practical application, for example, when the single pipe connection block is used in the half-meter layer between the layers, the two ends of the short steel pipe less than half a meter are welded to the short pipe with spherical connection blocks; the well shape, single pipe, Installation of connection blocks such as spheres, and well-shaped connection blocks are mostly used in the columns of the steel frame, the main body of the tower crane, and the inner shaft of the elevator. 10. Two gong wires 11 are installed at the bottom for fixing. With this single-plug double-hook joint, especially during decoration, rooms or walls can be added according to the wishes of the homeowner, and rooms can be increased or decreased at any time. The wall will be made by the homeowner at will; the double-hook joint of the steel pipe has a rotating double-hook joint 25 on one side, which can also be welded on the corresponding joint. After the rotating double-hook joint, the strength of the steel pipe has not been reduced. The summarized results can reduce the difficulty in production and processing, do not need to consider the direction of welding double hooks, and can be installed manually during installation, which is convenient and reliable.

Double-hook manual docking of steel structure components such as steel pipes and connecting blocks with steel frame technology, use manual docking "double-hook docking device" to connect all components, and complete various large, medium and small stadiums, buildings, halls, etc. The steel frame of the building and various types of tower cranes, gantry cranes, mobile cranes, and steel frames of various types of bridge steel columns, beam frames, etc.: First, it completely breaks the traditional architectural concept, construction technology, construction procedures and engineering materials; secondly, it is no longer possible to look at these building products according to traditional concepts. Traditional building products are, for example, housing. Building products combine all the upper and lower layers into a main body, and the force at one point is decomposed by the whole main body. The gravity of this kind of building product can be said to be negligible to its own weight in the study of mechanics; thirdly, in view of the above Point, as long as the steel frame of this kind of building has a little impact, it will be resolved by the whole main body. For example, adding bulletproof glass and steel plate wall to the periphery of the building wall can also withstand the impact of man-made war; Fourth, assembly and dismantling The steel frame of this kind of building is very simple and easy. This kind of assembly does not require mechanical equipment. As long as the personnel are manually arranged, as long as the manpower is properly arranged, ten to dozens of floors are installed a day, and a high-rise building is often erected overnight. Unloading is relatively simple, and the high-rise buildings here often disappear overnight. Unlike traditional building products, countless reinforced concrete is required for construction, and these waste reinforced concrete cannot disappear during dismantling.

The "fourth-generation housing" installed by the double-hook manual butt joint steel frame technology also includes various large, medium and small stadiums and halls: First, the traditional concept has been changed from the design, and the structural The network decomposition of steel pipes is used as a whole. For example, taking a cube as an example, connect the reinforced concrete cube with twelve steel pipes and sphere connecting blocks, and then add six steel pipes to the diagonal corners of the six faces and one steel pipe to the sphere diagonally in the middle. The connecting blocks are connected, and then such steel pipe cubes are connected one by one, so that the triangle is firmly stabilized and the whole main body is incomparable. Second, in terms of construction, since the weight of the main body can be ignored, there is no process of driving piles and burying beams in the ground; third, the original house is transmitted by gravity from top to bottom—of course There is also the transmission from the bottom to the top, because the transmission of gravity is much greater than the transmission from the bottom to the top, so it is impossible to understand - and after the application of this new technology, after the self-weight is greatly reduced, this kind of force transmission from the bottom to the top will appear To express it in another language, that is to say, when there is a huge force acting on a certain point of the subject, this force is decomposed into each point of force.

The "fourth-generation housing" installed by the double-hook manual docking steel frame technology has no process of driving piles and burying beams in the construction. , the ground is covered with two or three floors connected by meters, each divided into triangular cubes, and the floor space between each floor of the house and the vertical walls every 20 to 60 meters are also used. The ground is covered with triangular cubes, and the three-dimensional construction hoisting equipment on the construction site is integrated with the housing skeleton. The hoisting equipment is installed while the steel structure housing skeleton is raised. After the skeleton is installed, the main body of the hanger becomes the elevator shaft. When the house is completed as a whole, the preliminary construction is completed; the second step is the decoration and decoration of the house. This step is now the responsibility of the buyer. If this is the case, what the buyer buys is the "fourth generation housing" It is a space, so, according to the purchase price, it is only a few tenths of the "elevator room". Ten square meters; for the decoration of the house, all the floors, walls, stairs and furniture can be installed as "modules". Individuals can also afford it, and it is possible to set roads and parking spots at the door of each floor and each house. Therefore, I named the "fourth generation housing" "modular housing".

Human beings live in groups. In today's society, the more the population increases, the more the society develops, and the larger the urban population, the more modern the country is. The buildings are shoulder to shoulder, one taller than the other; the "modular house" of the "fourth generation housing" will surpass all "elevator rooms", for example, if the "modular house" is made into a "pyramid" shape, then the "modular house" Not just one hundred layers, but hundreds, even thousands of layers, and there is no need to think about it falling over.
