Description

Technical Field

[0001] The present invention relates to the technical field of steel beam construction, and in particular to a sliding construction device and method for a steel beam of a skylight roof of a commercial complex. Background Art

[0002] Large commercial complexes often design indoor lobbies or indoor pedestrian streets. The ceilings of lobbies and pedestrian streets often use glass skylights, which are also called skylights. Skylights often use steel structures as support for the top glass. The commonly used steel structure components are box-type steel beams. Box-type steel beams have the advantages of large span, convenient installation, fast construction, and light weight compared to concrete beams. However, during construction, because the span of the steel beam or part of the steel beam is large, if the entire steel beam is hoisted by a tower crane, the lifting performance requirements of the tower crane are high. If the tower crane is required to meet the lifting requirements of these steel beams, a large tower crane with good lifting performance must be installed. The installation of the tower crane is generally installed in the foundation stage, which leads to an increase in the cost of tower crane installation and use. In addition, because the main structure of the commercial building does not require such a large tower crane, it is too wasteful to install a large tower crane just to use a few large steel beams in the skylight.

[0003] If a truck crane is used for lifting, and if the truck crane is used for lifting outside the commercial building, since the steel structure is located in the center of the commercial roof, the lifting operation radius is large, and considering the anti-pole factor, a particularly heavy truck crane is required (based on past experience, the steel structure of the skylight roof of large commercial buildings in cities requires a 200T or above truck crane for lifting). The truck crane is large and the cost is also high. In addition, the commercial area is generally a basement roof. Due to the insufficient bearing capacity of the basement roof, the driving and operation of large vehicles on the basement roof requires the reinforcement of the basement roof, which will increase the cost again.

[0004] In addition, a patent with the title of patent: A steel beam sliding installation device and application number: 202122458325.2 has been published. This patent involves the installation of steel beams and other structures by adding tracks, jacking devices, and lifting devices in areas that cannot be lifted. First, more components need to be installed and arranged in the structure, which increases the construction period. Secondly, the length of the installed beam basically does not exceed the distance between the two tracks. At the same time, the length of the steel beam needs to be kept consistent, otherwise other lifting and moving structures will be added, and eventually a structure similar to a gantry crane will be formed to achieve the installation of steel beams, increasing the complexity of the structure. Summary of the invention

[0005] In order to solve the above problems, the present invention discloses a sliding construction device for a steel beam of a skylight roof of a commercial complex, comprising a traction rod fixed on a building body and an extension section assembled on the end of the steel beam.

[0006] One end of the extension section is provided with a protrusion, and the protrusion is embedded in the end of the steel beam, one side of the steel beam is interspersed with a pin shaft, and the pin shaft passes through the protrusion, and one side of the extension section is provided with a first lifting lug. The extension section is used to extend the length of the steel beam, and at the same time, it adopts a pin shaft fixed connection method, which has the advantage of fast disassembly and assembly.

[0007] The building body is provided with an embedded plate, the embedded plate is provided with a supporting plate, the lower end of the traction rod is assembled on the embedded plate, the upper end of the traction rod is fixedly connected with a hand chain hoist, and the hook of the hand chain hoist is matched with the first lifting ear. When the steel beam is placed on the upper end of the building body, its extension section is in contact with the upper end surface of the building body, and the steel beam is dragged by the hand chain hoist to be transferred to the installation position. The above-mentioned transfer and installation method of the steel beam has a simple structure, is easy to operate, and has a greatly reduced relative construction cost.

[0008] Preferably, a through hole is provided at the end of the pin shaft, and a split pin is inserted in the through hole. The split pin prevents the pin shaft from falling off.

[0009] Preferably, the side wall of the extension section is fixedly connected with steel bars, and when the steel beam is placed on the building, the steel bars are arranged vertically downward. That is, the steel beam is placed on the upper end surface of the building to prevent the end of the steel beam from slipping off the building during the pulling process. Therefore, steel bars are arranged, and the steel bars serve as limiters. When the end position of the steel beam deviates, the steel bars abut against the inner wall or outer wall of the building, limiting the end of the steel beam from continuing to move in its own length direction, thereby ensuring the safety of construction.

[0010] Preferably, the lower side wall of the traction rod is fixedly connected with a plurality of ear plates, and bolts and nuts are inserted into the ear plates to achieve fixed connection with the building body. The traction rod is installed on the buried plate by means of bolts and nuts, and this method can facilitate the disassembly and assembly of the traction rod.

[0011] A commercial complex skylight roof steel beam sliding construction method, comprising the following contents: Step 1: Before pouring the building, embedded plates and bolts and nuts are set at the installation position of the steel beam, that is, the embedded plates and bolts and nuts are all embedded parts; Step 2: The traction rod is installed on the embedded plate and the bolts and nuts, and the upper end of the traction rod is installed with a hand chain hoist. The hand chain hoist and the traction rod are components for transferring and lifting the steel beam. After meeting the installation requirements, the component is simple enough to reduce the construction cost. Step 3: Assemble the extension section at both ends of the steel beam through the pin shaft, then transfer the steel beam and place it flat on the upper end of the building, that is, the extension section is in contact with the building; Step 4: Install the hook of the hand chain hoist on the first lifting eye or the second lifting eye preset on the steel beam, then drag the steel beam to the installation position, and use the hand chain hoist to drag the steel beam. Note that it is necessary to ensure the position of both ends of the steel beam during the movement, and then control the dragging speed of the two hand chain hoists; Step 5: The steel beam is suspended at the installation location, the extension section is removed, and the steel beam is lowered onto the pallet, and finally fixed to the building by welding. If the hook is fitted on the first lifting lug, the hook needs to be changed to the second lifting lug; Step 6: Remove the drawbar and install it at the next location. Repeat the above steps to complete the installation of all steel beams.

[0012] Preferably, in step 4, graphite lubricant is applied to the extension section or the upper end of the building body to reduce friction and increase drag resistance.

[0013] The beneficial effects of the present invention are as follows: 1. Install a traction rod on the building, and use a hand winch to drag the steel beam on the building. The structure used is simple and easy to use, which is conducive to shortening the construction period, thus greatly reducing the construction cost.

[0014] 2. Place the steel beam on the building and drag it. While ensuring that the steel beam does not fall from the building, there is no limit on the length of the steel beam, which means it is more friendly to the construction of buildings with multiple cross-sectional sizes.

[0015] 3. Only hand winches are used to achieve the functions of dragging and lifting. Manual pulling is more conducive to controlling the movement of the steel beam end and facilitating safe construction.

[0016] 4. The steel beam is finally welded to the inner buried plate, and the traction rod is fixed to the outer buried plate. Therefore, the fixing of the traction rod will not add additional structure, which is conducive to reducing construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. Example 1

[0021] like Figures 1 to 4 As shown, a commercial complex skylight roof steel beam sliding construction device includes a traction rod 1 fixed on a building body 5 and an extension section 9 assembled on the end of a steel beam 8. The traction rod 1 is made of two 180*90*5mm square steel columns welded together to form an outer cross-sectional size of 180*180mm. In this way, the bearing capacity of the traction rod 1 is better than that of directly using 180*180*5mm square steel. Of course, 180*180*8mm square steel can also be used.

[0022] A protrusion is provided at one end of the extension section 9, that is, the extension section 9 is a stepped structure, and the protrusion is embedded in the end of the steel beam 8. A pin shaft 14 is interspersed on one side of the steel beam 8, and the pin shaft 14 passes through the protrusion. The extension section and the steel beam 8 are connected together through the protrusion and the pin shaft 14. At the same time, this connection method has the advantage of convenient disassembly and assembly. A first lifting ear 11 is provided on one side of the extension section 9. The first lifting ear 11 is a plate member and a through hole is provided in the middle. It is a common matching structure in the common transportation process.

[0023] The building body 5 is provided with an embedded plate 3, which is arranged in pairs and is respectively located on both sides of the building body 5. The embedded plate 3 is provided with a support plate 2, which is located on the inner side of the building body 5 and is used to support the steel beam 8 to facilitate the subsequent fixation of the steel beam 8. The lower end of the traction rod 1 is assembled on the embedded plate 3, and the upper end of the traction rod 1 is fixedly connected with a hand chain hoist 7. The hook of the hand chain hoist 7 is matched with the first lifting ear 11. The hand chain hoist 7 is manually controlled to drag the steel beam 8 to the current position of the embedded plate 3 to achieve fixation. Relatively speaking, the hand chain hoist 7 can also be replaced with an electric hoist to reduce labor intensity, but the moving speed of the steel beam 8 needs to be strictly controlled.

[0024] A through hole is provided at the end of the pin shaft 14, and a cotter pin 13 is inserted in the through hole. The cotter pin 13 prevents the pin shaft 14 from falling off the steel beam 8. At the same time, cotter pins 13 are provided at both ends of the pin shaft 14 to facilitate the removal of the pin shaft 13 from the bottom or top.

[0025] The side wall of the extension section 9 is fixedly connected with a steel bar 10, and the steel bar 10 here can be replaced by other structures, such as plates, etc. The steel bar 10 is used because the component is a commonly used structure on the construction site and there are many cutting wastes. When the steel beam 8 is placed on the building body 5, the steel bar 10 is set vertically downward. The steel bar 10 here plays a limiting role. In the process of dragging the steel beam 8, if the end of the steel beam 8 is offset, the steel bar 10 will resist the side wall of the building body 5 to prevent the end of the steel beam 8 from continuing to offset.

[0026] The lower side wall of the traction rod 1 is fixedly connected with a plurality of ear plates 6, and the structure of the ear plate 6 is the same as that of the first lifting ear 11. Bolts and nuts 4 are inserted on the ear plate 6 to achieve a fixed connection with the building body 5. The specific structure of the embedded plate 3 and the bolts and nuts 4 is that before the building body 5 is poured, the embedded plate 3 is set on the template, and then the bolts are used to pass through the two embedded plates 3, and then the ends of the bolts are threadedly connected to the nuts. When installing the traction rod 1, the ear plate 6 is sleeved on the end of the screw rod, and then fixed with a nut, thus completing the fixing operation of the traction rod 1. By using this connection method, the supporting strength is guaranteed. At the same time, when the next steel beam 8 is installed, the traction rod 1 can be transferred and fixed here. Example 2

[0027] like Figures 5 to 9 As shown, a commercial complex skylight roof steel beam sliding construction method includes the following contents: Step 1: Before pouring the building body 5, an embedded plate 3 and bolts and nuts 4 are arranged at the installation position of the steel beam 8, that is, the embedded plate 3 and the bolts and nuts 4 are all embedded parts to ensure the bearing strength; Step 2: The traction rod 1 is installed on the embedded plate 3 and the bolts and nuts 4 to fix the traction rod 1, and a hand chain hoist 7 is installed on the upper end of the traction rod 1. The hand chain hoist 7 is used for towing the steel beam 8; Step 3: Assemble the extension section 9 at both ends of the steel beam 8 through the pin shaft 14, and then transfer the steel beam 8 and lay it flat on the upper end of the building body 5, as shown in the following figure. Figure 5 As shown, a support rod can be added to the building body 5 when necessary, specifically, the extension section 9 is in contact with the building body 5; Step 4: Install the hook of the hand chain hoist 7 on the first lifting lug 11 or the second lifting lug 12 preset on the steel beam 8, and then drag the steel beam 8 to the installation position. If the dragging resistance is large, apply graphite lubricant on the extension section 9 or the upper end of the building body 5 to reduce the friction, such as Figure 6 , Figure 7 and Fig. 9 As shown, after being dragged to the installation position, the steel beam 8 is changed in posture; Step 5: The steel beam 8 is suspended in the installation position, such as Figure 8 As shown, after the extension section 9 is disassembled, the steel beam 8 is lowered onto the support plate 2, and finally fixed to the building body 5 by welding, specifically, the end of the steel beam 8 is welded to the embedded plate 3; Step 6: Remove the drawbar 1 and install it at the next position, repeat the above steps to complete the installation of all the steel beams 8.

[0028] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
