[0001] The present invention relates to the technical field of building construction, and in particular to a steel bar truss floor deck installation structure and method. Background Art

[0002] Steel truss floor decking is a prefabricated and assembled floor system widely used in modern buildings. It is mainly composed of steel trusses and corrugated steel sheets or concrete slabs. This system perfectly combines the speed advantages of steel structures and the rigidity characteristics of concrete structures, and has become an important bonus item in green building scores.

[0003] When installing floor decking, it is necessary to precisely control the distance between the floor decking on both sides of the beam and the center line of the beam. Usually, workers are required to survey in advance and pop up the edge lines of the floor decking on the beam. During installation, workers are required to manually control the placement points, and the misalignment distance of the plate ends is required to be within 5MM. As a result, the construction is extremely demanding on the workers' craftsmanship and technology, with high technical requirements and cumbersome and inconvenient operation. Summary of the Invention

[0004] The present invention discloses a steel truss floor deck installation structure and method, aiming to solve the technical problems of the existing operation method for installing floor decks, the construction process of which is extremely demanding on the workers' craftsmanship and technology, has high technical requirements and is cumbersome and inconvenient to operate.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A steel truss floor deck installation structure comprises a plurality of evenly distributed beams, with a plurality of mutually spliced ​​floor decks laid on top of the beams;

[0007] The top of the beam frame is provided with a connection mechanism for fixing the floor deck, and the connection mechanism includes a plurality of cross frames symmetrically installed on the top of the beam frame;

[0008] A positioning mechanism for centering the connecting mechanism is provided between each of the connecting mechanisms. The positioning mechanism includes a component distributed at the center line of the top of the beam frame, and a bolt sleeve is distributed inside the component. The two ends of the bolt sleeve are respectively threadedly connected to a bolt rod, and the thread directions of the two bolt rods are opposite. A joint is rotatably installed at the end of each bolt rod. A splicing groove is provided at the end of each cross frame. The splicing grooves are spliced ​​in pairs to form a closed circular structure, and the joint is inserted into the interior of the splicing groove;

[0009] The floor deck is first positioned and installed on the top of the beam frame through the positioning mechanism, and the connecting mechanism is assisted to position and connect and fix the floor deck along the center line of the beam frame.

[0010] By setting a positioning mechanism on the top of the beam frame, the positioning mechanism is used to first position itself to the center line of the beam frame and welded, and then the connecting mechanisms are installed in batches on both sides of the welded positioning mechanism. The distance between each group of connecting mechanisms and the center line of the beam frame is independently adjusted according to process requirements, and the floor decking is quickly installed on both sides of the connecting mechanism, thereby greatly improving the process efficiency and accuracy of the floor decking installation. At the same time, the welded connecting mechanism and positioning mechanism can further improve the structural strength of the floor decking after installation.

[0011] In a preferred embodiment, the connecting mechanism also includes several circular grooves evenly opened on the top of the cross frame, the ends of the floor decking plates are hooked into the circular grooves, a galvanized sheet is fixedly installed on the bottom of the cross frame, the ends of the floor decking plates are placed on the top of the galvanized sheet, and each of the two ends of the cross frame is symmetrically provided with a plug interface and a plug block, the plug block is engaged with the inside of the plug interface, and several groups of the cross frames are connected in pairs through the plug interface and the plug block.

[0012] By setting a cross frame structure on the top of the beam frame, using the positioning mechanism to adjust the placement of the cross frame, the floor decking is quickly connected through the circular groove and galvanized sheet, and the reinforcement between the two is completed by welding. At the same time, plug-in interfaces and plug-in block structures are respectively provided at both ends of the cross frame. The plug-in interfaces and plug-in blocks are quickly connected to complete the connection between the cross frames, thereby further improving the convenience of using this equipment.

[0013] In a preferred solution, the positioning mechanism further includes a straight groove extending through the interior of each of the bolt rods, and straight rods are symmetrically fixed on both sides of the component, and the straight rods extend through the interior of the straight groove.

[0014] By setting up a component structure with its own bolt sleeve, workers place the component on the top of the beam frame, and rotate the bolt sleeve to drive a group of bolt rods and joints to move outward synchronously until the joints are flush with both sides of the beam frame. At this time, the component is placed on the top of the beam frame and welded to complete the positioning of the component itself. After that, the joint is rotated and inserted into the inside of the splicing groove to complete the installation of the cross frame. At the same time, the bolts are rotated a second time to adjust the position of the cross frame, completing the self-positioning and positioning of the cross frame and floor deck installation points, thereby greatly improving the convenience of traditional floor deck installation.

[0015] In a preferred solution, the floor decking comprises several galvanized plates and cover plates evenly laid on the top of the beam frame. A group of web reinforcement bars are symmetrically welded on the top of each galvanized plate, and three symmetrically distributed straight-spin reinforcement bars are welded on the outside of the web reinforcement bars. The ends of the straight-spin reinforcement bars located above are vertically welded with riveted reinforcement bars, and the riveted reinforcement bars are inserted into the inside of the circular groove. At the same time, one end of the galvanized plate is placed on the top of the galvanized sheet, and the other end of the galvanized plate is placed on the top of the cover plate.

[0016] The floor deck structure, which is constructed with a galvanized sheet base and connected by web bars and straight-turn steel bars, not only ensures the structural strength of the floor deck when filled with concrete, but also ensures the rapid installation of the floor deck and the stability of the subsequent welding structure through the insertion of riveted steel bars and circular grooves, as well as the overlapping relationship between the galvanized sheet and galvanized sheet.

[0017] In a preferred solution, edge seals and sealing grooves are respectively provided on both sides of the galvanized sheet, the edge seals are engaged with the inside of the sealing grooves, and the galvanized sheets that are bonded together are fixed by the edge seals and the sealing grooves.

[0018] By arranging edge sealing and sealing groove structures on both sides of the galvanized sheet respectively, the galvanized sheets are fixed to each other by using the edge sealing and sealing groove, thereby ensuring the structural strength and stability of the galvanized sheets after connection.

[0019] In a preferred solution, a central interval is provided through the middle of the component, the bolt sleeve is distributed inside the central interval, sliding grooves are provided through both sides of the central interval, and both sides of the bolt sleeve pass through the interior of the sliding groove. At the same time, elastic protrusions are symmetrically provided on the upper and lower sides of the sliding groove, and the bolt sleeve is squeezed and contacted with the elastic protrusions.

[0020] By arranging a center interval and a sliding groove structure in the middle of the component, the sliding groove structure is used to adjust the height of the bolt sleeve and the bolt rod, thereby facilitating workers' observation when positioning the component and improving the convenience of operating the equipment.

[0021] A method for installing a steel bar truss floor deck comprises the following steps:

[0022] S1: A worker positions and welds the positioning mechanism at the top center line of the beam;

[0023] S2: A worker symmetrically connects each set of the connecting mechanisms to both sides of the positioning mechanism, and adjusts the distance between each set of the connecting mechanisms and the center line of the beam frame through the positioning mechanism;

[0024] S3: After adjusting the position of the connecting mechanism, a plurality of the floor decking plates are evenly laid between the beam frame and the connecting mechanism in sequence;

[0025] S4: After the floor decking is laid and fixed, the floor decking and the connecting mechanism are fixed to the top of the beam frame by welding;

[0026] S5: After the floor decking and the connecting mechanism are welded and fixed, the entire sealed frame is poured with concrete.

[0027] From the above, it can be seen that the steel bar truss floor deck installation structure and method provided by the present invention have the following technical effects.

[0028] First: By setting up a component structure with its own bolt sleeve, workers place the component on the top of the beam frame, and drive a group of bolt rods and joints to move outward synchronously by rotating the bolt sleeve until the joints are flush with both sides of the beam frame, completing the positioning of the component itself. Then, the joints are rotated and inserted into the inside of the splicing groove to complete the installation of the cross frame. At the same time, the bolts are rotated a second time to adjust the position of the cross frame with the center line of the beam frame as the origin, completing the self-positioning and positioning of the cross frame and floor decking installation points, thereby greatly improving the convenience of traditional floor decking installation.

[0029] Secondly, a cross-frame structure is provided on the top of the beam frame, and the placement of the cross-frame is adjusted by using a positioning mechanism. The floor decking is quickly installed by riveting the steel bars and inserting the round grooves. The galvanized sheets and galvanized sheets are laid out and connected by welding, which ensures the stability during the subsequent concrete pouring. At the same time, plug-in interfaces and plug-in block structures are provided at both ends of the cross-frame. By using the quick docking of the plug-in interfaces and the plug-in blocks, the cross-frames can be quickly connected with each other during large-scale floor decking installation, and a specific number of positioning mechanisms can be used to complete the synchronous spacing adjustment, thereby further improving the convenience of using this equipment.

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] The present invention discloses a steel bar truss floor deck installation structure and method, which are mainly used in scenarios where floor decks are positioned and installed.

[0048] Reference Figures 1 to 15 A steel truss floor deck installation structure includes a plurality of evenly distributed beams 1, and a plurality of mutually spliced ​​floor decks 2 are laid on top of the beams 1;

[0049] The top of the beam frame 1 is provided with a connection mechanism 3 for fixing the floor deck 2. The connection mechanism 3 includes several groups of cross frames 301 symmetrically installed on the top of the beam frame 1;

[0050] A positioning mechanism 4 for centering the connecting mechanism 3 is provided between each pair of connecting mechanisms 3. The positioning mechanism 4 includes a component 401 distributed at the center line of the top of the beam frame 1. A bolt sleeve 402 is distributed inside the component 401. The two ends of the bolt sleeve 402 are respectively threadedly connected to a bolt rod 403. The thread directions of the two bolt rods 403 are opposite, and a joint 404 is rotatably installed at the end of each bolt rod 403. A splicing groove 405 is provided at the end of each cross frame 301. The splicing grooves 405 are spliced ​​in pairs to form a closed circular structure. The joint 404 is inserted into the interior of the splicing groove 405.

[0051] The floor deck 2 is first positioned and installed on the top of the beam frame 1 through the positioning mechanism 4, and the auxiliary connecting mechanism 3 is positioned along the center line of the beam frame 1 and connected and fixed.

[0052] In this embodiment: workers position and weld the positioning mechanism 4 at the top center line of the beam frame 1, and then symmetrically connect each group of connecting mechanisms 3 to the two sides of the positioning mechanism 4, and adjust the distance between each group of connecting mechanisms 3 and the center line of the beam frame 1 through the positioning mechanism 4. After adjusting the position of the connecting mechanism 3, several floor decking plates 2 are evenly laid between the beam frame 1 and the connecting mechanism 3 in turn. After the laying and fixing of the floor decking plates 2 are completed, the floor decking plates 2 and the connecting mechanism 3 are fixed to the top of the beam frame 1 by welding. After completing the welding and fixing of the floor decking plates 2 and the connecting mechanism 3, concrete is poured for the entire sealed frame.

[0053] Reference Figures 4 to 7 In a preferred embodiment, the connecting mechanism 3 also includes several circular grooves 302 evenly opened on the top of the cross frame 301, the ends of the floor decking 2 are hooked into the circular grooves 302, and the bottom of the cross frame 301 is fixedly installed with a galvanized sheet 303. The ends of the floor decking 2 are placed on the top of the galvanized sheet 303. The two ends of each cross frame 301 are symmetrically provided with plug interfaces 304 and plug blocks 305, and the plug blocks 305 are engaged with the inside of the plug interfaces 304. Several groups of cross frames 301 are connected in pairs through the plug interfaces 304 and the plug blocks 305.

[0054] The worker welds the positioning mechanism 4 to the top center line of the beam 1, and then connects each set of cross frames 301 symmetrically to both sides of the positioning mechanism 4, and adjusts the distance between each set of cross frames 301 and the center line of the beam 1 through the positioning mechanism 4. Before this process, if the worker needs to install a cross frame 301, the worker holds a single cross frame 301, connects the plug interface 304 at the end of the cross frame 301 with the plug block 305 at the end of another cross frame 301, and after adjusting the position of the cross frame 301, the worker can The worker holds the floor decking 2 and places the two ends of the floor decking 2 between the two beam frames 1. At the same time, the end of the floor decking 2 passes through the circular groove 302 and is placed on the top of the galvanized sheet 303. Then other floor decking slabs 2 are placed in sequence, so that the ends of the floor decking slabs 2 are connected to the cross frame 301 and the side surfaces are in contact and engaged with each other. Among them, the side walls of each cross frame 301 are penetrated by a number of evenly distributed circulation areas 306 to ensure that after the entire frame is installed, there is enough space for the poured concrete to circulate.

[0055] Reference Figures 5 to 10 In a preferred embodiment, the positioning mechanism 4 further includes a straight groove 406 extending through each bolt rod 403 , and straight rods 407 are symmetrically fixed on both sides of the component 401 , and the straight rods 407 extend through the straight groove 406 .

[0056] The worker holds the component 401 and roughly places it on the top center line of the beam 1. Thereafter, the worker rotates the bolt sleeve 402, causing the bolt sleeve 402 to drive the two bolt rods 403 to move outward synchronously. During this process, the bolt rod 403 will be restricted by the straight groove 406 and the straight rod 407, so that it cannot rotate and can only move. The moving bolt rod 403 will synchronously drive the joint 404 to move until the extended length of the joint 404 is the same as the width of the beam 1. At this time, the worker aligns the joint 404 with both sides of the beam 1, locates the center line of the beam 1 and welds the component 401 to the top center position of the beam 1 (such as Figure 15 As shown), the bolt sleeve 402 is then rotated in the opposite direction to reset the joint 404. The worker then holds a single cross frame 301, aligns and engages the splicing groove 405 at the end of the cross frame 301 with the joint 404, completing the installation of the single cross frame 301. If the worker needs to install an additional cross frame 301, the worker holds a single cross frame 301 and connects the plug interface 304 at the end of the cross frame 301 with the plug block 305 at the end of another cross frame 301. After that, the worker rotates the bolt sleeve 402 as needed to adjust the distance between each group of cross frames 301 and the center line of the beam frame 1.

[0057] Among them, the middle part of the component 401 is penetrated by a central section 4011, the bolt sleeve 402 is distributed inside the central section 4011, and sliding grooves 4012 are penetrated on both sides of the central section 4011. The two sides of the bolt sleeve 402 pass through the interior of the sliding groove 4012. At the same time, elastic protrusions 4013 are symmetrically provided on the upper and lower sides of the sliding groove 4012. The bolt sleeve 402 is squeezed and contacted with the elastic protrusion 4013. When the worker rotates the bolt sleeve 402 to position the component 401, the bolt sleeve 402 is distributed at the bottom of the sliding groove 4012 (such as Figure 14 As shown), the worker uses a wrench to rotate the bolt sleeve 402 through the middle section 4011. At this time, the lowered joint 404 is close to the beam frame 1, which is convenient for the worker to observe; when the worker installs the cross frame 301, the worker pushes the bolt sleeve 402 from the bottom of the sliding groove 4012 to the top, and in this process, the elastic protrusion 4013 will squeeze and engage the bolt sleeve 402 to maintain the stability of the current state of the bolt sleeve 402.

[0058] Furthermore, a snap-fitting portion 4041 is provided at the end of the joint 404, and a through groove 4051 is provided on the outer side of the splicing groove 405. After the snap-fitting portion 4041 slides into the interior of the splicing groove 405 through the through groove 4051, the worker rotates the joint 404 to cause the snap-fitting portion 4041 and the through groove 4051 to be misaligned, thereby enhancing the connection strength between the joint 404 and the cross frame 301.

[0059] It should be noted that mounting grooves 4014 are vertically opened at both ends of the component 401, and studs 5 are installed inside the mounting grooves 4014. The component 401 is welded to the top of the beam 1 through the studs 5. At the same time, studs 5 are also installed on the top of the contact end of the galvanized plate 201 and the galvanized sheet 303. The galvanized plate 201 and the galvanized sheet 303 are welded through the studs 5 and fixed to the top of the beam 1.

[0060] Reference Figures 1 to 4 In a preferred embodiment, the floor deck 2 includes several galvanized plates 201 and a cover plate 207 evenly laid on the top of the beam frame 1. A group of web reinforcement bars 202 are symmetrically welded on the top of each galvanized plate 201, and three symmetrically distributed straight-spin reinforcement bars 203 are welded on the outside of the web reinforcement bars 202. The end of the straight-spin reinforcement bar 203 located above is vertically welded with a riveted reinforcement bar 204, and the riveted reinforcement bar 204 is inserted into the inside of the circular groove 302. At the same time, one end of the galvanized plate 201 is placed on the top of the galvanized sheet 303, and the other end of the galvanized plate 201 is placed on the top of the cover plate 207.

[0061] When installing the floor decking 2, the worker holds the floor decking 2 and places the two ends of the floor decking 2 between the two beams 1 respectively. At the same time, the end of the riveted steel bar 204 is passed through the circular groove 302 and the galvanized sheet 201 is placed on the top of the galvanized sheet 303. Then other floor decking 2 are placed in turn, and the sealing plate 207 is placed on the top of the beam 1, so that one end of the floor decking 2 is connected to the cross frame 301, the other end is placed on the top of the sealing plate 207, and the side surfaces of the floor decking 2 are in contact with each other. Among them, the galvanized sheet 201 is respectively provided with a sealing edge 205 and a sealing groove 206 on both sides, and the sealing edge 205 is engaged with the inside of the sealing groove 206. The two galvanized sheets 201 that are attached to each other are fixed by the sealing edge 205 and the sealing groove 206, and the sealing is ensured at the same time.

[0062] Working principle: When in use, the worker holds the component 401 and roughly places the component 401 on the top center line of the beam 1. Thereafter, the bolt sleeve 402 is rotated, causing the bolt sleeve 402 to drive the two bolt rods 403 to move outward synchronously. During this process, the bolt rod 403 will be restricted by the straight groove 406 and the straight rod 407, so that it cannot rotate and can only move. The moving bolt rod 403 will synchronously drive the joint 404 to move until the extended length of the joint 404 is the same as the width of the beam 1. At this time, the worker aligns the joint 404 with both sides of the beam 1, locates the center line of the beam 1 and welds the component 401 to the top of the beam 1 through the bolt 5. At this time, the component 401 is fixed at the center of the top of the beam 1 (such as Figure 15 As shown), no manual measurement and calibration is required;

[0063] Then the worker pushes the bolt sleeve 402 upward from the bottom of the sliding groove 4012 to the top. During this process, the elastic protrusion 4013 squeezes and engages the bolt sleeve 402 to maintain the stability of the bolt sleeve 402. Then the bolt sleeve 402 is rotated in the opposite direction, causing the joint 404 to reset and move. After that, the worker holds a single cross frame 301, aligns and engages the splicing groove 405 at the end of the cross frame 301 with the joint 404, and completes the installation of the single cross frame 301. After that, the worker rotates the bolt sleeve 402 as needed to adjust the distance between each group of cross frames 301 and the center line of the beam frame 1, making the adjustment and calibration process more convenient.

[0064] If the worker needs to install a cross frame 301, the worker holds a single cross frame 301 and connects the plug interface 304 at the end of the cross frame 301 with the plug block 305 at the end of another cross frame 301. After that, the worker rotates the bolt sleeve 402 according to the needs to adjust the distance between each group of cross frames 301 and the center line of the beam frame 1; then the worker holds the floor deck 2 and places the two ends of the floor deck 2 between the two beam frames 1 respectively, and at the same time, the end of the riveted steel bar 204 is taken out from the circular groove 302. Pass through and place the galvanized sheet 201 on top of the galvanized sheet 303, then place other floor decking plates 2 in turn, and at the same time place the sealing plate 207 on the top of the beam frame 1, so that one end of the floor decking plate 2 is connected to the cross frame 301, the other end is placed on the top of the sealing plate 207, and the side surfaces of the floor decking plates 2 are in contact with each other and engaged with each other, then the galvanized sheet 201 and the galvanized sheet 303 are welded through the bolts 5 and fixed to the top of the beam frame 1. After welding and fixing are completed, the entire sealed frame is poured with concrete.
