Description

(5) СПбСОБ МОНТАЖА КОЛОНН(5) FSTSOB ASSEMBLY OF COLUMNS

Изобретение относитс к строительству и может быть использовано при монтаже сборных железобетонных колонн.The invention relates to the construction and can be used for the installation of precast concrete columns.

Известен способ монтажа колонн, заключающийс в шарнирной устайовке колонны на фундаментную плиту, закреплени ее на плите и замоноличивани 1 .There is a known method of mounting the columns, which consists in hinging the installation of the column on the base plate, fixing it on the plate and laying it in a monolith 1.

Наиболее близким по технической сущности и достигаемому результатуо к предлагаемому вл етс способ монтажа колонн, включающий установку фундаментной плиты, устройство фундамента , заведение в него колонны с последующей выверко:1 и замоноличиванием 2.The closest in technical essence and the achieved result to the proposed method is the installation of columns, including the installation of a foundation slab, the construction of the foundation, the establishment of a column in it, followed by alignment: 1 and monolithing 2.

Недостатком известных способов вл етс то, что дл осуществлени .монтажа колонн этими способами требуетс двойна организаци процесса бетонных работ: по бетонированию фундаментов (стаканов) под колонны и замоноличиванию стыка колонн вA disadvantage of the known methods is that in order to carry out the installation of columns by these methods, a double organization of the concrete work process is required: concreting foundations (glasses) under the columns and embedding the column joint into

стаканах фундаментов.Это требует применени различных конструкций опалубок , механизмов дл укладки и уплотнени бетонной смеси, различного состава бетонной смеси (дл фундамента и стыка), что усложн ет процесс и увеличивает трудоемкость и продолжительность работ.foundation cups. This requires the use of various formwork designs, mechanisms for laying and compacting concrete, different concrete mixes (for the foundation and the joint), which complicates the process and increases the labor intensity and duration of work.

Цель изобретени - снижение трудо10 емкости работ.The purpose of the invention is to reduce labor capacity.

Поставленна цель достигаетс тем, что согласно способу монтажа колонн, включающему установку фундаментной плиты, устройство фундамента, The goal is achieved by the fact that according to the method of installation of the columns, including the installation of the base plate, the foundation,

Claims

15, the conductor is fixed, columns are put into it, followed by alignment and monolithing, the conductor is made with formwork panels, in the form of the foundation and fixed on the base plate, and the foundation is installed, and the column is monolithic at the same time by feeding the concrete mixture to the conductor. 396. FIG. 1 shows schematically the fixing of the conductor on the funch: to the coping plate and the installation of a column in it; in fig. 2 - monolithing, column joint. After installing the conductor 1c with the formwork 2 according to the foundation shape on the base plate 3 and fixing the screws 4 with the screws 4, the column 5 is installed using, for example, a mounting crane 6, and the column end is fixed in the design position with the pin 7 concreted in the base plate and the alignment of the column and temporary fastening in the design position is made by the screws 8 of the conductor. Then, using a bunker 9, the concrete tO is laid in the formwork of the conductor, the shape of the foundation 11. The proposed installation method allows the column to be concreted in the foundation and monolithing the column joint in one technological process. At the same time, the labor intensity for the manufacture of the foundation is reduced, since it is necessary to prefine only the foundation slab, and the concreting of the rest of the foundation part is performed simultaneously with the monolithing of the column joint. By combining concrete materials in a single process, the number of mechanisms for laying and compacting the concrete mixture is reduced, and the concrete mixture is applied to the same composition; the duration of the construction work is reduced. The invention of the method of mounting columns, including the installation (of the cement plate, foundation, fixing the conductor, building the column in it, followed by alignment and monolithing, characterized in that, in order to reduce the labor-intensive work, the conductor is made with formwork shields according to the shape of the foundation and fixed on the base plate, and laying the foundation and monolithing the column is carried out simultaneously by feeding concrete cMecVi to the conductor.
