For the problem of non-uniform height of the column, the applicant proposes a method for preparing the column with the required height by partially prefabricating and partially casting the column, wherein the height of the prefabricating part is uniform, the prefabricated column can be a prism or a cylindrical prefabricated column as a component with extremely high standardized layer, and the height of the cast-in-situ part is determined according to the requirement. The column is divided into two parts, namely a column head and a column shaft, wherein the column shaft is completely prefabricated or mostly prefabricated, and the column head is completely cast-in-situ or mostly cast-in-situ. For example, the floor height of a certain item is 3.5 and 3.4 meters respectively, the height of the beam lower column is 2.7 meters and 2.6 meters after subtracting the beam height from the floor height, the floor height of the floor of a certain area is 3.6 meters, but the beam height is 0.8 meters and 0.9 meters, and the height of the beam lower column is 2.8 meters and 2.7 meters after subtracting the beam height from the floor height; thus, the heights of the lower beam column are three of 2.6 meters, 2.7 meters and 2.8 meters. Considering the condition of 2.6 m of the lowest height, only 2.6 m of columns are prefabricated, and the longer columns are prepared by partially prefabricating and partially casting in situ.
The first subject of the utility model is a column head cast-in-place mold for casting a column head on top of a prefabricated column. Referring to fig. 1, the column head cast-in-situ mold comprises a mold body 1 formed by assembling at least two templates, wherein the mold body 1 is divided into an upper section and a lower section, the upper section of the mold body forms a column head cavity 11, the column head cavity 11 is used for cast-in-situ forming a column head, and the top of the column head cavity 11 is an open casting opening; the lower section of the die body forms a columnar column body cavity 12, the column body cavity 12 is matched with the prefabricated column 2, the lower section of the die body is used for being sleeved at the top of the prefabricated column 2 and fixed on the prefabricated column 2, and therefore the bottom of the column body cavity 12 is open. The mold body 1 may have a shape with equal size, i.e. the shape and size of the column head cavity 11 and the column shaft cavity 12 are identical in horizontal cross section, and the mold body 1 may have a shape with equal size, i.e. the area of the column head cavity 11 in the horizontal cross section is larger than the area of the column shaft cavity 12 in the horizontal cross section.
The lower section of the die body is provided with at least two layers of fixing positions along the circumferential direction, and each layer of fixing positions comprises at least two fixing holes 13. The fixing holes 13 are used for fixing the lower section of the die body to the prefabricated column 2, and each layer of fixing position is provided with at least two fixing holes 13, so that the die body 1 can be firmly fixed to the prefabricated column 2. The fixing holes 13 of different fixing positions are adopted for at least two layers of fixing positions, so that partially prefabricated partially cast-in-situ columns with different total heights can be formed.
In order to make the stress at each fixing hole 13 substantially uniform, the balance of the stress is ensured, and the fixing holes 13 of each layer of fixing position are arranged along the circumferential isocenter angle of the lower section of the die body or symmetrically arranged about the central axis of the lower section of the die body. For example, when two fixing holes 13 are arranged at each layer of fixing position, the connecting line of the two fixing holes 13 passes through the central line of the lower section of the die body; when three fixing holes 13 are arranged on each layer of fixing position, the connecting lines of the three fixing holes 13 form a regular triangle, and the center of the regular triangle is positioned at the center line of the lower section of the die body.
In order to obtain columns of more various heights, the lower section of the mould body is provided with three or more layers of fixing positions. In order to facilitate the installation of the die body 1, the number of the fixing holes 13 of each layer of fixing positions is equal, and the fixing holes 13 corresponding to the fixing positions of each layer are positioned on the same straight line which is parallel to the central line of the lower section of the die body. The spacing between two layers of fixtures is equal or unequal, for example, the spacing between two adjacent layers of fixtures is 50mm.
The second subject of the utility model is a precast column cast-in-place structure, as shown in fig. 1, which comprises a precast column 2 and the column head cast-in-place mold described in the first subject, wherein at least two connecting seats are embedded in the outer side of the precast column 2 along the circumferential direction, the connecting seats are used for fixing a mold body 1, and the connecting seats can be mounting grooves or mounting holes reserved in the precast column 2 and can be metal pieces embedded in the precast column 2. The column body cavity 12 is matched with the prefabricated column 2, the lower section of the die body is assembled on the outer side of the prefabricated column 2, and the fixing hole 13 of any layer of fixing position of the lower section of the die body is connected with the connecting seat of the prefabricated column 2 through a connecting piece.
In order to facilitate the installation and removal of the mould body 1, the connectors are bolts 3. In order to ensure the stability of the prefabricated column 2, at least two diagonal braces 4 are also provided on the outside of the prefabricated column 2. In order to balance the stress of each diagonal brace 4, the connection points of each diagonal brace 4 and the prefabricated column 2 are arranged along the circumferential isocenter angle of the prefabricated column 2 or symmetrically arranged about the central line of the prefabricated column 2. Considering that the construction site often cannot arrange diagonal braces 4 around the prefabricated column 2, the prefabricated column 2 can be supported by two diagonal braces, at this time, the connection points of each diagonal brace 4 and the prefabricated column 2 are two, and the two connection points form a central angle which is right with the central line of the prefabricated column 2. The position of the prefabricated column 2 for connecting the diagonal bracing 4 and the position for installing the connecting piece can be separated or unified. In order to simplify the structure of the prefabricated column 2 and reduce the difficulty of prefabrication, one end of the diagonal strut 4 is connected to a connecting seat of the prefabricated column 2.
After the height of the prefabricated column 2 is determined, the prefabricated column 2 is produced by a factory according to the determined fixed height, the prefabricated column 2 is transported to the site and hoisted, the die body 1 is assembled and fixed before the lifting hook is taken when the prefabricated column 2 falls down, diagonal braces 4 are installed when necessary, templates of other cast-in-place parts are supported, beam column node steel bars and other steel bars are bound, and finally concrete is poured. And after the concrete reaches the design strength, the diagonal brace 1 is taken down, and the die body 1 is removed.
