Hinge variable cross-section elevator shaft formwork
The invention relates to the technical field of building structure construction formworks, and provides a hinge variable cross-section elevator shaft formwork which comprises four-wall formworks, corner formworks and formwork folding and unfolding frames; the number of the four-wall formworks and the number of the corner formworks are both four, the corner formworks are right-angle corner formworks, and each corner formwork is connected with two adjacent four-wall formworks through hinges; the formwork folding and unfolding frame is positioned in the center of the shaft formwork and is connected with the four four-wall shaft formworks through adjustable pull rods respectively; and the adjustable pull rods can drive the four-wall formworks to get close to or get away from the center of theshaft formwork, and then the corner formworks are driven to get close to or get away from the center. According to the hinge variable cross-section elevator shaft formwork, the four corners of the shaft wall can be guaranteed to be 90 degrees, and no groove is formed in the wall surface. The formwork folding and unfolding frame is positioned in the center of the shaft formwork, by means of the structure, the construction requirement can be met, it is guaranteed that an elevator shaft is square, machining is easy and convenient, formwork erecting and demolding are easy and light, operation is easy, and labor and time are saved; the corner formworks and the four-wall formworks are designed to be in tongue-and-groove lap joint, grout leakage can be effectively prevented, and concrete at formwork splicing seams is smooth and free of grooves.
本发明涉及建筑结构施工模板技术领域，提供了一种铰链变截面电梯井筒模，包括四壁模板、角模板及模板收放架；四壁模板和角模板数量均为4个，角模板为直角角模板，每个角模板与相邻的2个四壁模板之间通过铰链连接；模板收放架位于筒模的中心部位，模板收放架通过可调拉杆与4个四壁模板分别连接；可调拉杆能带动四壁模板向筒模中心靠近或远离，进而带动角模板向中心靠近或远离。本发明可保证筒壁四角为90度，墙面无凹槽。筒模中心设有中心模板收放架，这种结构能满足施工需要，确保电梯井筒方正，加工简便，支模与脱模简单轻快，操作简单，省工省时；角模板与四壁模板设计为企口搭接，可有效地防止漏浆，模板拼逢处混凝土平整无凹槽。
