Description

Technical Field

[0001] The invention relates to the technical field of building engineering, in particular to an energy-saving building steel bar truss floor deck bottom formwork connector. Background Art

[0002] The truss made of steel bars as the upper chord, lower chord and web members connected by resistance spot welding is called a steel truss. The combined load-bearing plate connected to the bottom plate by resistance spot welding is called a steel truss floor deck. During construction, the steel truss floor deck is fixed between two load-bearing beams and poured directly with concrete. The bottom formwork bears the gravity of the concrete, and the steel truss provides unsupported rigidity for the bottom formwork. Compared with the traditional floor deck that supports concrete through the bottom formwork, the steel truss floor deck speeds up the construction progress and enhances the supporting effect.

[0003] At present, when making steel truss floor decking, it is necessary to connect the bottom formworks of each steel truss floor decking together. The bottom formworks of adjacent steel truss floor decking are generally connected together by buckles at both ends, or connected together by bolts and other connectors to avoid the problem of separation and leakage of the bottom formwork after pouring concrete.

[0004] However, in the traditional bottom formwork connection method, the two bottom formworks are often simply fixed by bolts. Although this connection method realizes the connection of the bottom formworks to a certain extent, due to the lack of sufficient tightening and fitting mechanism, the connection and fitting surfaces between the bottom formworks are often unable to achieve tight fitting, which leads to tiny gaps or uneven areas on the connection surfaces. These gaps or uneven areas may become potential channels for concrete leakage. Since a certain pressure is applied to the concrete during the pouring process, the concrete is easy to penetrate from these gaps. This leakage will not only affect the pouring quality of the concrete, but also have an adverse effect on the structural stability and service life of the bottom formwork, but also lead to waste of concrete materials due to leakage, which is not in line with the concept of energy conservation, emission reduction and green development advocated by the current society.

[0029] Embodiment 2: Based on the above embodiment, a sealing filling component 8 is provided on the inner wall of the installation box body 3 .

[0030] Furthermore, the sealing filling component 8 includes an annular tube 801, and the interior of the annular tube 801 fits and rotates with the outer wall of the driving rod 701, the inner wall of the annular tube 801 is fitted and slidably connected with an extrusion ring 802, the outer wall of the driving rod 701 is fitted with a push plate 803, and the interior of the push plate 803 is correspondingly provided with a slide groove 804, the outer wall of the driving rod 701 fits and slides with the inner wall of the slide groove 804, the inner wall of the slide groove 804 is fixedly connected with a ball 805, the outer wall of the driving rod 701 is provided with a guide groove 10 corresponding to the ball 805, and the outer wall of the ball 805 fits and slides with the inner wall of the guide groove 10, the push plate 803 is symmetrically fixedly connected with a push rod 806 on one side of the outer wall facing the extrusion ring 802, and the other end of the push rod 806 is fixedly connected to the outer wall of one side of the extrusion ring 802.

[0031] In this embodiment, during the rotation of the driving rod 701, the extrusion ring 802 is firstly connected by slidingly fitting with the inner wall of the ring tube 801, and the outer wall of the driving rod 701 is fitted with a push plate 803, and a slide groove 804 is correspondingly provided inside the push plate 803, and at the same time, the outer wall of the driving rod 701 fits and slides with the inner wall of the slide groove 804, and the inner wall of the slide groove 804 is fixedly connected with a ball 805, and the outer wall of the driving rod 701 is provided with a guide groove 10 corresponding to the ball 805, and at the same time, the outer wall of the ball 805 fits and slides with the inner wall of the guide groove 10, and the push plate 803 is symmetrically fixedly connected with a push rod 806 on one side of the outer wall facing the extrusion ring 802, and the other end of the push rod 806 is fixedly connected to the outer wall of one side of the extrusion ring 802, so that the ball 805 In cooperation with the guide groove 10, the push plate 803 can drive the extrusion ring 802 to move on the inner wall of the ring tube 801 through the push rod 806, and squeeze the filling liquid inside. At this time, a nozzle 807 is fixedly connected through the upper outer wall of the ring tube 801, and a supplementary pipe 808 is fixedly connected to the lower outer wall of the ring tube 801, and the other end of the supplementary pipe 808 passes through the interior of the mounting box body 3 and is fixedly connected to a supplementary head 809. Furthermore, a one-way valve component is installed in the nozzle 807 and the supplementary pipe 808 to control the one-way flow of the filling liquid, so that when the filling liquid is squeezed, the filling liquid can be sprayed out through the nozzle 807 to cover the connecting surface of the two bottom mold body main bodies 1, and can penetrate and fill the tiny gaps and bumps between the bottom mold connecting surfaces.

[0032] When the filling liquid is sprayed, that is, when the ball 805 has completed the guide groove 10, the outer wall of the driving rod 701 is provided with an annular groove 11, and the inner wall of the annular groove 11 is connected with the inner wall of the guide groove 10, so that the ball 805 will slide into the annular groove 11, that is, in the subsequent process, the push plate 803 will stop at the current position and will not move. Further, when the ball 805 moves in the guide groove 10, the two clamping rings 708 have not yet clamped and driven the mounting rod 5, but are only approaching the mounting rod 5. At this time, the two bottom template bodies 1 The connecting surface of the two bottom template bodies 1 has not been tightened, so that the filling liquid can be sprayed onto the connecting surface of the two bottom template bodies 1 through the nozzle 807. When the ball 805 slides into the annular groove 11, the spraying process will be stopped. At this time, the clamping ring 708 will be in contact with the mounting rod 5 and ready to be clamped and driven, so that the tightening effect between the bottom template bodies 1 can be used to squeeze the filling liquid, which not only helps the filling liquid to penetrate deeper into the gaps and bumps, but also ensures the uniform distribution of the filling liquid on the connecting surface, thereby further improving the tightness of the connection between the bottom molds.

[0033] Then, during disassembly, a tension spring 810 is provided on the outer wall of the driving rod 701, and one end of the tension spring 810 is fixedly connected to the outer wall of one side of the push plate 803, and the other end of the tension spring 810 is fixedly connected to the outer wall of one side of the rope drum 703, so that the push plate 803 can be reset by the tension spring 810. At this time, the filling liquid can be refilled into the ring tube 801 from the replenishing head 809 at the bottom to achieve the effect of reuse, reducing the purchase of new materials and the generation of waste.

[0034] Furthermore, when the multiple driving handles 702 are rotated, they are rotated and tightened in sequence from the middle position of the bottom template body 1 to both sides, ensuring that the entire connecting component is evenly stressed during the tightening process.

[0035] As described above, when the bottom molds are connected, the guide groove 10 and the rolling ball 805 cooperate during the rotation of the driving rod 701, so that before the two bottom molds are tightened, the filling liquid in the ring tube 801 can be pushed by the extrusion ring 802, so that the filling liquid is sprayed on the connecting surfaces of the two bottom molds, and the tiny gaps and bumps between the connecting surfaces of the bottom molds can be penetrated and filled. At the same time, the ring groove 11 and the rolling ball 805 cooperate after the spraying, so that the filling liquid can be squeezed through the tightening effect between the bottom molds, which not only helps the filling liquid to penetrate deeper into the gaps and bumps, but also ensures the uniform distribution of the filling liquid on the connecting surface, thereby further improving the tightness of the connection between the bottom molds.

[0036] Working principle: First, fix the installation box body 3 and the installation rod 5 to the bottom of the side close to the two bottom template bodies 1 through the installation plate 1 2 and the installation plate 2 4, and then push the two bottom template bodies 1 to approach each other, and insert the installation rod 5 into the installation box body 3 through the insertion hole 6, and then drive the driving rod 701 to rotate by rotating the driving handle 702, so that the two pull ropes 704 synchronously pull the two slides 706, so that when the slide 706 drives the slide rod 707 to move, the two clamping rings 708 can clamp the installation rod 5 inward synchronously and drive it to move during the movement through the cooperation of the inclined groove 711 and the guide rod 709, so that the two bottom template bodies 1 are tightened to each other, reducing the gap between the connecting surfaces of the bottom template bodies 1; Then, when the tension is completed, the fixing pin 713 in the driving handle 702 is pushed into a fixing hole 714 to fix the driving handle 702, thereby achieving the tension and fixation of the two bottom template bodies 1; Then, during the rotation of the driving rod 701, when the ball 805 moves in the guide groove 10, the two clamping rings 708 have not yet clamped and driven the mounting rod 5, but are only approaching the mounting rod 5. At this time, the connecting surfaces of the two bottom template bodies 1 have not yet been tightened, so that the filling liquid can be sprayed to the connecting surfaces of the two bottom template bodies 1 through the nozzle 807. When the ball 805 slides into the annular groove 11, the spraying process will be stopped. At this time, the clamping ring 708 will be in contact with the mounting rod 5 and ready to clamp and drive, so that the tensioning effect between the bottom template bodies 1 can be used to squeeze the filling liquid, which not only helps the filling liquid to penetrate deeper into the gaps and bumps, but also ensures the uniform distribution of the filling liquid on the connecting surface, thereby further improving the connection tightness between the bottom molds.
