Novel construction method of cast-in-place special-shaped beam structure

YANG WEI / XU YONGHUI / CHEN YUANFANG

The invention discloses a novel construction method of a cast-in-place special-shaped beam structure. The novel construction method comprises the following steps: step 1, segmenting; step 2, cutting; step 3, laying; step 4, supporting; step 5, fixing; step 6, pouring; wherein in the first step, the special-shaped beam is segmented according to the length of the special-shaped beam; wherein in the step 2, the beam pouring template required by the outer surface of each section of the special-shaped beam in the step 1 is cut to obtain a template in a required shape, and then the cut beam pouring template is spliced on the outer surface of the special-shaped beam; wherein in the third step, the local beam pouring formworks needed by all the sections of special-shaped beams are sequentially laid according to the shapes of the special-shaped beams; according to the special-shaped beam construction method, the special-shaped beam is segmented, and each section of the special-shaped beam is laid through the pouring formworks, so that the needed special-shaped beam structure is formed through the pouring formworks spliced for multiple times, the error of the special-shaped beam structure is reduced, and the stability of the special-shaped beam structure is improved.

本发明公开了现浇异形梁结构的新型施工方法，包括以下步骤：步骤一，分段；步骤二，切割；步骤三，铺设；步骤四，支撑；步骤五，固定；步骤六，浇筑；其中在上述步骤一中，根据异形梁的长度对异形梁进行分段处理；其中在上述步骤二中，对步骤一中每段异形梁外表面所需的浇梁模板进行切割处理得到所需形状的模板，然后将切割后的浇梁模板拼接在异形梁的外表面上；其中在上述步骤三中，将每段异形梁所需的局部浇梁模板根据异形梁的形状依次进行铺设处理；该发明，通过将异形梁进行分段处理，利用浇筑模板对每段的异形梁进行铺设，从而利用多次拼接的浇筑模板组成所需的异形梁结构，降低了异形梁结构的误差，从而提高了异形梁结构的稳定性。
