Description

Technical Field

[0001] The invention belongs to the technical field of fixing building foundation engineering components, and in particular relates to a staircase template device for building construction. Background Art

[0002] In buildings, stairs are used to connect floors and when there is a large height difference, so that people can go from low floors to high floors. Stairs are composed of continuous steps, platforms and enclosure components. Before building stairs in building construction, stair templates are needed to assist in pouring concrete. The stair templates also need to support the poured concrete. After the concrete is formed, the stair templates are removed. However, the current stair templates still expose some disadvantages in actual use: most of the existing stair templates for building construction are installed by workers by piecing together the plates one by one, and then supported by external steel bars, etc. Frequent piecing together and installing increases the workload of the workers; not only that, when removing the stair templates, the operation process is also correspondingly complicated, and it cannot be quickly disassembled and assembled. The construction process is laborious and time-consuming, and the efficiency is low; secondly, most of the existing stair templates for building construction are prepared and assembled according to the width of the stairs, and it is easy to find a plate of suitable width, so that the concrete cannot be well protected, which is not conducive to the molding of concrete. It is easy to have deviations after molding, and it is not convenient to adjust according to the width of the stairs, which makes it have great limitations in use and poor applicability and recyclability.

The baffle is U-shaped and includes a web and two wing plates. The web is parallel to the mounting plate, and the two wing plates correspond to the two side blocks and are coplanar. Two parallel side plates are arranged between the web and the mounting plate. The two side plates are perpendicular to the supporting plate. T-slots are respectively provided at both ends of the outer side surfaces of the side plates, and the extension direction of the T-slots is perpendicular to the supporting plate. The wing plates and the side blocks are connected with vertically penetrating bolts through internal threaded holes, and the inner ends of the bolts are vertically connected with round plates. The two side plates are slidably plugged with the two bolts and the round plates on the corresponding sides through the T-slots.

[0006] To further improve the above technical solution, the T-slot passes through the side plate along the extension direction for easy processing.

[0007] Furthermore, the rectangular groove passes through the side block along the extension direction so that the mounting plate can abut against the upper surface of the support plate after being inserted.

A rectangular groove 32 is opened on the inner side of the side block 3, and the side block 3 is slidably connected with a mounting plate 33 through the rectangular groove 32. The two ends of the mounting plate 33 are slidably connected in the rectangular groove 32. A convex column 34 is welded at the lower right corner of the front side of the side block 3. The rear part of the upper end surface of the bottom plate 4 is fixedly connected with a bracket 41, and the top end of the bracket 41 is rotatably connected with the convex column 34. The middle part of the upper end surface of the bottom plate 4 is fixedly connected with a fixing plate 42, and the left side of the upper end surface of the bottom plate 4 is fixedly connected with the fixing plate 42. A fixed block 43 is fixedly connected, and both ends of the screw rod 5 are rotatably connected to the fixed plate 42 and the fixed block 43. The left end of the screw rod 5 passes through the fixed block 43, and the left end of the screw rod 5 is fixedly connected to a turntable 51. The screw rod section between the fixed plate 42 and the fixed block 43 is threadedly connected with an internal thread block 52. The screw rod 5 passes through the middle of the internal thread block 52, and the bottom end of the internal thread block 52 is in sliding contact with the upper end surface of the support plate 1 but is not connected. A second fixed axis 521 is provided in the middle of the top end of the internal thread block 52, and the second fixed axis 521 passes through the bottom end of the Y-shaped rod 53. The second fixed axis 521 is rotatably connected to the Y-shaped rod 53, and the two top ends of the Y-shaped rod 53 are rotatably connected to the first fixed axis 13 respectively.

At the same time, the bolt 23 drives the side plate 2 to move, and changes the distance between the two side plates 2 so that the distance is the same as the width of the stairs to be built. Stop rotating the bolt 23 to maintain the distance state.

[0024] Before building the stairs, the template device is moved to the position of the stairs to be built through the base plate 4, and then the inclination angle of the support plate 1 is adjusted, and the handle on the turntable 51 is turned to make the turntable 51 drive the screw rod 5 to rotate, and the screw rod 5 rotates on the fixed plate 42 and the fixed block 43. The thread on the screw rod 5 cooperates with the thread in the internal thread block 52, so that the internal thread block 52 moves in the axial direction of the screw rod 5, and the support plate 1 is driven to rotate around the boss 34 through the Y-shaped rod 53, and the height position of the left end of the support plate 1 changes. During the rotation of the support plate 1, the boss 34 and the bracket 41 on the base plate 4 rotate relative to each other, the height of the right side position of the support plate 1 does not change, and the height of the left side of the support plate 1 changes, so that the inclination angle of the support plate 1 can be adjusted; the operator can stop rotating the turntable 51 as needed to fix the support plate 1 at a suitable angle. Then directly align the two ends of the mounting plate 33 with the side block 3, move downward to slide the two ends of the mounting plate 33 into the rectangular groove 32; then align the T-slot 21 of the side plate 2 with the circular plate 22, slide the T-slot 21 of the side plate 2 and the circular plate 22 to connect and install, and the quick installation can be completed.

[0025] When laying concrete on the support plate 1, the baffle 11 and the mounting plate 33 protect the left and right sides of the concrete (the top plate can be covered), and the side plate 2 protects the front and rear of the concrete. When removing the formwork, after loosening it, the mounting plate 33 is pulled out from the rectangular groove 32, and then the T-slot 21 of the side plate 2 is taken out from the circular plate 22, and then the turntable 51 is reversed, and the internal thread block 52 is driven to move by the screw rod 5 to reduce the inclination angle of the support plate 1, thereby separating the support plate 1 from the formed concrete, and completing the quick disassembly.
