Method for adjusting pouring size of beam bottom wedge block
The invention relates to a method for adjusting the pouring size of a beam bottom wedge block. The method for adjusting the pouring size of the beam bottom wedge block comprises the following steps that for a precast beam, a laser gradienter is placed on the upper surface of a beam plate precast pedestal, and the height a of projection laser of the laser gradienter is measured; calculating the central height difference h0 + a between the projection laser of the laser level meter and the central position of the lower surface of the wedge-shaped block and four-corner height differences h1 + a, h2 + a, h3 + a and h4 + a among four corners of the lower surface of the wedge-shaped block; the method comprises the following steps: measuring four points corresponding to height differences h1 + a, h2 + a, h3 + a and h4 + a from laser projected by a laser gradienter to four corners on the inner walls of the four corners of a groove reserved in a beam and slab prefabricating pedestal by using a measuring scale and the laser gradienter, marking the four points, sequentially paving dry sand and a pre-embedded steel plate, and then measuring whether the central height difference at the center of the groove accords with h0 + a or not, whether the size accords with the design or not is judged, and it is ensured that the volume in the groove is completely matched with the size of the designed wedge block after the dry sand and the pre-embedded steel plate are laid. The method for adjusting the pouring size of the beam bottom wedge block is convenient to operate and accurate in measurement, multiple precast beams or cast-in-place beams can be measured at the same time, and the construction time is saved.
本发明涉及一种调整梁底楔形块浇筑尺寸的方法。该调整梁底楔形块浇筑尺寸的方法，包括以下步骤：对于预制梁：将激光水平仪置于梁板预制台座上表面，量测激光水平仪投影激光的高度△a，计算激光水平仪投影激光与楔形块下表面中心位置的中心高差h0+△a以及楔形块下表面四个角之间的四角高差h1+△a、h2+△a、h3+△a、h4+△a，使用测量尺与激光水平仪配合在梁板预制台座上预留的凹槽四角内壁上量出与激光水平仪投影激光至四角的高差分别为h1+△a、h2+△a、h3+△a、h4+△a的对应的四个点并进行标记，依次铺设干砂和预埋钢板，之后测量凹槽中心处的中心高差是否符合h0+△a，判断是否与设计相符，确保铺设干砂和预埋钢板后，凹槽内的容积与设计的楔形块尺寸完全吻合。本发明的调整梁底楔形块浇筑尺寸的方法操作便捷，测量精确且可以同时进行多片预制梁或现浇梁的测量，节省施工时间。
