Description

Technical Field

[0001] The present invention relates to the technical field of floor bearing plates, and specifically provides a steel bar truss floor bearing plate that is convenient for support. Background Art

[0002] The production of a steel bar truss floor bearing plate is to first combine and weld three specifications of steel bars into a steel bar truss, and then use the resistance spot welding processing method to combine and weld the steel bar truss and the bottom formwork into one body, which can not only meet the assembly standards of prefabricated buildings, but also meet the quality requirements of floor engineering and steel bar engineering construction.

[0003] For example, a non-support steel bar truss floor bearing plate with the publication number CN217759484U includes a bottom plate, a triangular frame, a fixing rod, etc. There are two bottom plates in total, and the two bottom plates are symmetric left and right. Four fixing rods are connected to the left and right sides of the top of each of the two bottom plates by bolts, and a triangular frame is fixedly connected between the eight fixing rods on each bottom plate. The bottom plates can be spliced and fixed in a clamping form through a clamping mechanism, so there is no need to splice and fix the bottom plates by welding, which can improve the efficiency of people's splicing and fixing of the bottom plates. However, in the prior art, the floor bearing plate is usually made of hot-dip galvanized profiled steel sheet with a thickness between 0.7 and 1.0 mm, and can be spliced to adapt to different building requirements and structural layouts. The existing splicing method is installed by sliding splicing, so that after a splicing error occurs subsequently, a certain space must be reserved to disassemble the floor bearing plate. When it is necessary to disassemble and replace the floor bearing plate between two floor bearing plates, it is necessary to first remove the floor bearing plate blocking on one side, the operation is relatively inconvenient, and the installation efficiency of the floor bearing plate is also reduced. Moreover, the splicing and fixing are carried out through spaced guide columns and clamping blocks, and the splicing strength of the floor bearing plate is limited. During subsequent concrete pouring, the floor bearing plate may be laterally unbalanced, reducing the use effect of the floor bearing plate.

[0004] Therefore, a steel bar truss floor bearing plate that is convenient for support is proposed to solve the above-mentioned problems. Summary of the Invention

Guided by the extrusion inclined block and extruded by the main body of the floor bearing plate, the side plate will deflect upward, driving the rotating shaft to rotate, causing multiple side plates to open up, facilitating the auxiliary pressing of adjacent main bodies of the floor bearing plate and improving the stability of splicing.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up the auxiliary structure and the steel bar structure, before construction, after the position of the cast-in-place beam is marked according to the design drawings, the formwork support is erected. The height of the top supports on both sides of the structural beam is adjusted according to the elevation. After the adjustment is completed, two steel sheathing timbers are placed in the trays. A support rod is installed between adjacent top supports, and the connecting parts at both ends of the support rod are fixedly installed with pins in the mounting rings. Then, the reinforcement beam formwork is laid on the formwork support. The beam formwork includes a beam bottom formwork and a beam side formwork, and a double-sided adhesive tape with a width of 1.5 mm is pasted at the contact part between the top of the beam side formwork and the main body of the floor bearing plate. After that, the laying of the main body of the floor bearing plate begins. The main body of the floor bearing plate protrudes 5 mm into the beam, and the contact part between the main body of the floor bearing plate and the beam side formwork is compacted, so that the double-sided adhesive tape is fully adhered to avoid leakage of mortar. Secondly, at this contact part, 50-mm-long iron nails are used for fixation to prevent the displacement of the floor bearing plate under the action of external forces; By setting up the combined structure, the operator aligns two main bodies of the floor bearing plate and rotates the bolt. The bolt rotates downward into the sleeve, driving the limit rod to rotate. The limit rod drives the rotating cover to rotate. The rotating cover drives the rotating ring to rotate. The rotating ring drives two pulling ropes to wind. The pulling ropes drive the moving plate to move towards the rotating ring. The moving plate drives the top block to slide inside the main body of the floor bearing plate, and the moving plate will stretch the return spring. The movement of the moving plate will also squeeze the inclined surface of the insert block. The insert block is extruded and slides out of the inner part of the side groove. The insert block drives the connecting plate to move, and the connecting plate compresses the auxiliary spring, so that the insert block is stuck into the slot on the adjacent main body of the floor bearing plate, thus completing the splicing of adjacent main bodies of the floor bearing plate. Since the bolt and the sleeve are in threaded connection, the bolt will not rotate after rotation, thereby improving the stability of the connection between the insert block and the slot; By setting up the locking structure, the operator rotates the top disc, which drives the lead screw to rotate. The outer rod limits the threaded sleeve. The rotation of the lead screw causes the threaded sleeve to descend. The threaded sleeve drives the insertion rod to descend. The insertion rod is inserted into the jack, and the downward movement of the insertion rod will also drive the mounting plate and the side plate to descend. Guided by the extrusion inclined block and extruded by the main body of the floor bearing plate, the side plate will deflect upward, causing multiple side plates to open up, facilitating the auxiliary pressing of adjacent main bodies of the floor bearing plate. The side plate drives the rotating shaft to rotate, and the rotating shaft acts on the torsion spring. During subsequent disassembly, the elastic force of the torsion spring will drive the rotating shaft and the side plate to rotate back to the original position. By inserting multiple insertion rods into the jacks, it is convenient to stably position adjacent main bodies of the floor bearing plate, improve the splicing strength of the main body of the floor bearing plate, and reduce the situation of lateral imbalance during the pouring of the main body of the floor bearing plate.

[0031] Embodiment 1: As Figure 3 - Figure 5 shown, before construction, after the position of the cast-in-place beam is marked according to the design drawings, the formwork support is erected. The height of the top supports 21 on both sides of the structural beam is adjusted according to the elevation. After the adjustment is completed, two steel sleeve woods 24 are placed in the tray 23. A support rod 25 is installed between adjacent top supports 21. The connecting parts 26 at both ends of the support rod 25 are fixedly installed on the installation ring 22 through pins. Then, the reinforcement beam formwork is laid on the formwork support. The beam formwork includes a beam bottom formwork and a beam side formwork. A double-sided adhesive tape with a width of 1.5 mm is pasted at the contact part between the top of the beam side formwork and the floor slab main body 1. After that, the laying of the floor slab main body 1 is started. The floor slab main body 1 protrudes into the beam by 5 mm, and the contact part between the floor slab main body 1 and the beam side formwork is compacted to make the double-sided adhesive tape fully adhered to avoid slurry leakage. Secondly, 50-mm-long iron nails are used to fix this contact part to avoid the displacement of the floor slab under the action of external forces.

Inside the main body 1 of the floor bearing plate, an inner groove 45 is opened. On both sides inside the inner groove 45, moving plates 48 are symmetrically and slidably installed. The moving plates 48 are fixedly connected to the pulling ropes 47.

[0034] The limiting rods 44 are slidably connected with the vertical groove. The rotating ring 46 is located inside the inner groove 45. On the top of the moving plate 48, a top block 49 is fixedly connected. The top block 49 is slidably connected with the main body 1 of the floor bearing plate. On one side outside the moving plate 48, a reset spring 410 is fixedly connected. One end of the reset spring 410 is fixedly connected to the inner wall of the inner groove 45.

[0035] The connecting unit further includes two insertion blocks 414 slidably installed on the side of the main body 1 of the floor bearing plate. The inclined surface of the insertion block 414 abuts against the moving plate 48. Between the outer side of the insertion block 414 and the inside of the inner groove 45, an auxiliary spring 412 is fixedly installed.

[0036] On the side of the main body 1 of the floor bearing plate, side grooves 411 are symmetrically opened. The insertion blocks 414 are slidably connected with the side grooves 411. The number of the side grooves 411 is the same as that of the insertion blocks 414. The auxiliary springs 412 and the connecting plates 413 are both located inside the inner groove 45. On the side of the main body 1 of the floor bearing plate, slots 415 are symmetrically opened. The insertion blocks 414 are snap-fitted with the slots 415.

[0037] Embodiment 2: As Figure 6 - Figure 9 shown, the operator aligns two main bodies 1 of the floor bearing plates, rotates the bolt 43, the bolt 43 screws downward into the sleeve 42, the bolt 43 drives the limiting rod 44 to rotate, the limiting rod 44 drives the rotating cover 41 to rotate, the rotating cover 41 drives the rotating ring 46 to rotate, the rotating ring 46 drives the two pulling ropes 47 to wind, the pulling ropes 47 drive the moving plates 48 to move towards the rotating ring 46, and the moving plates 48 drive the top blocks 49 to slide inside the main body 1 of the floor bearing plate.

[0038] The movable plate 48 will stretch the return spring 410, and the movement of the movable plate 48 will also squeeze the inclined surface of the plug block 414. The plug block 414 is squeezed and slides out from the inside of the side groove 411. The plug block 414 drives the connecting plate 413 to move, and the connecting plate 413 compresses the auxiliary spring 412, so that the plug block 414 is stuck in the slot 415 on the adjacent floor deck body 1, thereby completing the splicing of the adjacent floor deck bodies 1. Since the bolt 43 and the sleeve 42 are threadedly connected, the bolt 43 will not rotate after being rotated, thereby improving the stability of the connection between the plug block 414 and the slot 415.

[0039] A locking structure 5 is symmetrically provided on the top of the floor deck body 1. The locking structure 5 includes a screw rod 52 rotatably mounted on the top of the floor deck body 1. An insert rod 55 is symmetrically slidably mounted on the outer side of the screw rod 52.

A side plate 510 is fixedly connected to the middle of the outer side of the rotating shaft 59, and torsion springs 511 are symmetrically sleeved on both sides of the outer side of the rotating shaft 59. The two ends of the torsion spring 511 are fixedly connected to the mounting plate 58 and the side plate 510 respectively.

[0043] Example 3: Figure 10 - Figure 14 As shown, the operator rotates the top plate 51, and the top plate 51 drives the screw rod 52 to rotate, and the outer rod 54 limits the threaded sleeve 53. The rotation of the screw rod 52 causes the threaded sleeve 53 to descend, and the threaded sleeve 53 drives the insertion rod 55 to descend, and the insertion rod 55 is inserted into the insertion hole 56. The descent of the insertion rod 55 will also drive the mounting plate 58 and the side plate 510 to descend.

By inserting multiple insertion rods 55 into the insertion holes 56, it is convenient to stably position the adjacent floor bearing plate bodies 1, improving the splicing strength of the floor bearing plate bodies 1 and reducing the lateral imbalance of the floor bearing plate bodies 1 during pouring.

[0045] Working principle: When using this device, first, as Figure 1 - Figure 14 shown, before construction, after the position of the cast-in-place beam is marked according to the design drawings, the formwork support is erected. The heights of the top supports 21 on both sides of the structural beam are adjusted according to the elevation. After the adjustment is completed, two steel sheathing timbers 24 are placed in the trays 23. Then, the reinforcement beam formwork is laid on the formwork support.
