Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a method for lifting and intercepting a template of a staircase step adapted to steel bars. Background Art

[0002] As an important component of vertical transportation between floors in a building, the history of stairs can be traced back to the image of a heavy house on bronze ware during the Warring States Period in China. In Italy from the 15th to the 16th century, indoor stairs gradually moved from closed spaces to open spaces, becoming an important part of architecture. In modern buildings, stairs are not only used for transportation between floors, but also serve as an important escape route for fire in high-rise buildings.

[0003] In the existing cast-in-place staircase construction, it is usually necessary to first erect an overall scaffolding, and then successively erect the main keel, lay the formwork, tie the steel mesh, etc. In order to ensure the construction quality, construction joints and wooden beams are set up according to the design requirements. When pouring concrete, a second pouring is carried out with the construction joint as the boundary. Before the second pouring, the construction waste in the rear half of the formwork needs to be cleaned, and the pouring is continued after the construction joint is closed until the wooden beams are removed and the subsequent sealing work is completed.

[0004] However, this secondary pouring construction method is not only inefficient, but also has many operational inconveniences. Since the entire stair construction process is carried out in mid-air, the construction workers' working space is limited, the operation is difficult, and the safety hazards are relatively large. Therefore, it is necessary to explore a more efficient and safe cast-in-place stair formwork construction method. Summary of the invention

[0005] The embodiment of the present invention provides a method for lifting and intercepting a template adapted to steel bars of a staircase step, by assembling the template of the stairs and tying the steel mesh on the ground in advance, and cleaning the assembled stairs to avoid the influence of construction waste on the structural strength during the subsequent grouting process, and further setting up a lifting device between the ground and the middle platform and the roof, and lifting the assembled stairs to the target setting position for fixing, so as to perform a grouting and forming, and the movable barrier plate can automatically fall off the interception plate after a certain period of time through a timer, so as to ensure the stress release after the concrete is solidified and formed, and finally the template can be removed, which solves the problem that the existing staircase construction process is complicated and difficult to operate.

[0009] Furthermore, the second staircase includes a second supporting frame, which is formed by two second main purlins arranged in parallel, and the first docking plate and the second docking plate identical to the first supporting frame are respectively arranged at relative positions thereof. The top of the second supporting frame is constructed by the same process as the first staircase, i.e., the laying of the template and the binding of the steel mesh, wherein the template is provided with a blocking seam in the lower third.

[0010] Furthermore, the movable blocking plate includes a first mounting plate, an electric telescopic rod and an intercepting plate.

Example

[0022] An embodiment of the present invention provides a method for lifting and intercepting a template of a staircase step adapted to a steel bar, comprising the following steps: S1, preparing construction materials for the first staircase 10, the middle platform 20 and the second staircase 40 according to the construction drawings; S2, erecting a scaffold 30 below the construction position of the intermediate platform 20, and building the intermediate platform 20 on top of the scaffold 30; S3, assembling the first staircase 10 and the second staircase 40 on the ground below the construction positions of the first staircase 10 and the second staircase 40; S4, setting a movable blocking plate 50 at the lower third of the second staircase 40, and applying a release agent on the movable blocking plate 50; S5, erecting a lifting device 60 at both ends of the construction position of the first staircase 10 and the second staircase 40, and cleaning the construction waste in the template 12 to keep the template 12 clean; S6, using the lifting device 60 to lift the assembled first staircase 10 and second staircase 40 to the construction site for fixing; S7, pouring cement mortar from bottom to top using grouting equipment and waiting for solidification; S8, after solidification is completed, the movable blocking plate 50 is automatically separated, and the formwork 12 and the scaffold 30 can be removed.

[0023] like Figure 1 , 3 As shown in Figure 4, the middle platform 20 includes two platform plates 21 spliced ​​together, and I-beams 22 are arranged around the platform plates 21. The bottom of the I-beam 22 is fixed to the top of the scaffolding 30 by bolts. The middle platform 20 is the main load-bearing platform connecting the first staircase 10 and the second staircase 40. The formwork 12 is assembled above the middle platform 20, and the steel mesh 13 is tied inside the formwork 12.

[0024] In this embodiment, the first staircase 10 includes a first supporting frame 11, which is composed of two first main purlins 1101 arranged in parallel, and a first docking plate 1102 and a second docking plate 1103 are respectively arranged at relative positions. A first docking groove 11021 is opened at the top center of the first docking plate 1102, and a second docking groove 11031 is opened at the top center of the second docking plate 1103. A template 12 is arranged on the top of the two first main purlins 1101. After the template 12 is fixed, a steel mesh 13 is tied in the template 12.

[0025] Furthermore, the second staircase 40 includes a second supporting frame 41, which is composed of two second main purlins 4101 arranged in parallel, and the first docking plate 1102 and the second docking plate 1103 which are the same as the first supporting frame 11 are respectively arranged at relative positions. The top of the second supporting frame 41 is constructed by the same process as the first staircase 10, that is, the laying of the formwork 12 and the binding of the steel mesh 13, wherein the formwork 12 is provided with a blocking seam 42 at the lower third, and an intercepting plate 54 is provided at the blocking seam 42, in order to provide a stress release interval after the poured concrete is solidified, so as to avoid deformation of the stairs caused by shrinkage and expansion of the concrete.

[0026] like Figure 1 and 9As shown, the movable blocking plate 50 includes a first mounting plate 51, an electric telescopic rod 52 and an intercepting plate 54.

A connecting arm 53 is vertically arranged at the end of the output shaft of the electric telescopic rod 52, and the top of the connecting arm 53 is arranged together with the bottom of the mounting plate. A sliding rail 5403 is arranged at one end of the intercepting plate 54 in the length direction away from the electric telescopic rod 52, and a second mounting plate 55 is arranged at the second main keel 4101 near the sliding rail 5403. A limiting block 5501 is arranged on the second mounting plate 55, and the sliding rail 5403 is slidably arranged on the limiting block 5501. The limiting block 5501 mainly provides a guiding function to ensure the sliding stability of the intercepting plate 54.

[0027] Furthermore, a plurality of movable grooves 5401 are provided on the top of the intercepting plate 54, and a protrusion 5402 extending outward is provided on the bottom of the intercepting plate 54. When the electric telescopic rod 52 is fully retracted, the protrusion 5402 abuts against the bottom of the second staircase 40. At this time, the intercepting plate 54 has no contact with the steel mesh 13 on the inner side of the second staircase 40. When the electric telescopic rod 52 is fully extended, the top of the intercepting plate 54 is located below the blocking seam 42.

[0028] Specifically, after the first staircase 10 and the second staircase 40 are assembled, the electric telescopic rod 52 is fully retracted. At this time, the intercepting plate 54 is located on the inner side of the formwork 12. A release agent is applied to the intercepting plate 54. When pouring concrete, the concrete is poured from bottom to top at one time and vibrated. During this process, there is no need to pour in two stages, which saves construction time. When the hardening standard of the concrete is met, the electric telescopic rod 52 is controlled to extend to move the intercepting plate 54 out from the inside of the formwork 12.

[0029] As a preferred embodiment, a timer 56 is provided on the first mounting plate 51, and the timer 56 is electrically connected to the electric telescopic rod 52. The disengagement time of the intercepting plate 54 is set by the timer 56. At the same time, an audible and visual alarm can be set on the first mounting plate 51. When the timing time is reached, an audible and visual alarm is sounded and the intercepting plate 54 is removed at the same time, reminding the construction personnel to proceed to the next step, thereby increasing the construction efficiency.

The lifting hook 65 is set together with the second docking plate 1103 on the first staircase 10, and the drive motor 6403 on the first lifting device is started. The first staircase 10 can be moved to the target position relative to one end of the middle platform 20. In this process, the two ends can be fixed by a bolt structure after the position is corrected using a crowbar. It should be noted that when assembling the first staircase 10, a movable roller 6502 can be placed on the end away from the middle platform 20 to facilitate docking during the lifting process.

[0032] When installing the second staircase 40, two lifting devices 60 of different heights are selected. The shorter one has the same size as the first lifting device (marked as the second lifting device here), and the taller one is the third lifting device. The second lifting device is arranged at the bottom edge of the middle platform 20, and it is opposite to the vertical docking center point of the opposite end of the second staircase 40. The third lifting device is arranged below the edge of the top floor, and it is opposite to the vertical docking center point of the opposite end of the second staircase 40.
