[0005] Further, the reinforcing part includes: a plurality of first reinforcing parts, a plurality of second reinforcing parts, the first column form is sequentially provided with a plurality of first reinforcing parts from top to bottom in parallel on the outside, the second column form is sequentially provided with a plurality of second reinforcing parts equal to the first reinforcing parts from top to bottom in parallel on the outside, two ends of the first reinforcing part are respectively fixedly connected with the outer end of adjacent second reinforcing part.
[0006] Further, the XPS board and the first column form are fixedly connected by a plurality of screws.
[0007] Further, the thickness of the XPS board is the same as the designed expansion joint width.
[0008] Further, the sizes of the first column template and the second column template are set according to the design size of the double column.
[0009] The utility model discloses a kind of integrated templates with narrow expansion joint double column, use the template to carry out construction, not only can not affect the installation quality and efficiency of double column template, but also can reduce the phenomenon that concrete surface appears damage due to template removal difficulty at expansion joint, guarantee construction quality, speed up construction speed. BRIEF DESCRIPTION OF DRAWINGS
[0010] Figure 1 It is structural schematic diagram of the utility model;
[0011] In the drawing: 1-double column reinforcement;2-XPS board;3-first column template;4-second column template;5-first reinforcing member;6-second reinforcing member;7-screw;
[0012] The drawings in the utility model are all schematic diagrams, and their sizes do not represent actual sizes;
[0013] The utility model will be described in detail below with reference to the drawings. DETAILED DESCRIPTION
[0014] The utility model will be further described below with reference to the drawings and examples:
[0015] As Figure 1 As shown in a kind of integrated templates with narrow expansion joint double column its characterized in that, including double column reinforcement 1, XPS board 2, two first column templates 3, two second column templates 4, reinforcing member, the double column reinforcement 1 is set in the position of to be poured double column, the XPS board 2 is set in the position of the double column reinforcement 1 between design expansion joint, two sides of the XPS board are respectively with the middle position of the first column template 3 Fixed connection, two first column templates 3 are relatively parallelly arranged, two second column templates 4 are relatively parallelly arranged, two ends of the second column template 4 are respectively with two first column templates 3 Fixed connection, two first column templates 3 and two second column templates 4 are fixedly spliced into a vertical column with rectangular inner cross section, the outside of the first column template 3 and the second column template 4 is set with reinforcing member.
[0016] Specifically, four integrated templates are used for integrated reinforcement when double column construction, XPS board 2 is used for separation in middle expansion joint, double column is poured simultaneously with concrete, when concrete strength reaches the condition of removing formwork, the template of double column is removed, and then XPS board 2 at expansion joint is removed. Double column concrete can not only be poured simultaneously, but also can ensure that concrete corner is not damaged when template is removed.
[0017] The reinforcing members comprise a plurality of first reinforcing members 5 and a plurality of second reinforcing members 6, the first column formwork 3 is externally provided with the first reinforcing members 5 in parallel from top to bottom in turn, the second column formwork 4 is externally provided with the second reinforcing members 6 in parallel from top to bottom in turn, the number of the second reinforcing members 6 is equal to that of the first reinforcing members 5, and the two ends of the first reinforcing members 5 are fixedly connected with the outer ends of the adjacent second reinforcing members 6 respectively.
[0018] The XPS plate 2 and the first column formwork 3 are fixedly connected by a plurality of screws 7.
[0019] The thickness of the XPS plate 2 is the same as the designed width of the expansion joint.
[0020] The sizes of the first column formwork 3 and the second column formwork 4 are set according to the design size of the double columns.
[0021] The use steps of the utility model are as follows: the double-column steel bars 1 are bound according to the requirements of construction drawings; the XPS plates 2 are further processed according to the width of the expansion joint and the width and height of the double columns; the processed XPS plates 2 are placed at the expansion joint position, the first column formwork 3 on one side of the double columns is installed first and temporarily fixed; the first column formwork 3 and the XPS plate 2 at the expansion joint are fixed firmly by using the screws 7; the first column formwork 3 on the opposite side is installed and fixed to the XPS plate 2 by using the same method; the second column formworks 4 on the remaining two sides are installed in turn, and then the remaining two sides are reinforced by using the reinforcing members; after the installation is completed, the double-column concrete is poured and vibrated at the same time; after the formwork is removed, the XPS plates 2 are removed by using a cutting machine, and the expansion joint is left.
