Description

Steel-concrete combined column embedded part structure

Technical Field

The utility model belongs to the technical field of the connecting device among the concrete is exclusively used in, specifically is steel-concrete combination post built-in fitting structure.

Background

The steel-concrete composite column is a column structure form which combines a steel structure column and a concrete column. The lower end of the steel-concrete composite column is connected with the foundation bearing platform, so that in order to better connect the steel-concrete composite column and the foundation into a whole, an embedded part of the steel-concrete composite column needs to be arranged on the foundation bearing platform so as to increase the connection strength of the steel-concrete composite column and the foundation. Present built-in fitting has mainly included rag bolt, through fixing rag bolt in pre-buried position, then use reinforcing bar etc. to support the location fixed, such operation mode often can lead to rag bolt's fixed strength not enough, leads to rag bolt to take place the skew easily, and then influences the connection in later stage, or in order to guarantee fixed strength, has used more reinforcing bar to support, and the reinforcing bar that leads to built-in fitting department is more, influences the setting of subsequent some foundation structure's reinforcing bar. It is very necessary to design an embedded part of the steel-concrete combined column which is convenient to fix.

Disclosure of Invention

An object of the utility model is to provide a steel-concrete composite post built-in fitting structure to solve the inconvenient problem of installing of built-in fitting of steel-concrete composite post among the prior art.

In order to achieve the purpose, the utility model discloses a basic scheme provides a steel-concrete combination post built-in fitting structure, including support and a plurality of rag bolt, the support includes annular locating plate, it has a plurality of locating holes to be annular permutation and distribute as the centre of a circle with the center of locating plate on the locating plate, the downside of locating plate is connected with the bracing piece that three slopes set up, the lower extreme of bracing piece is located the locating plate under, the locating hole is passed to rag bolt's upper end, rag bolt's lower extreme fixedly connected with anchor assembly, the below of locating plate is equipped with two at least location hoops, the location hoop cover establish in all rag bolt's the outside and with rag bolt fixed connection, rag bolt's lower.

The principle and the beneficial effect of the basic scheme are as follows: and a positioning plate is arranged and used for positioning the position of the foundation bolt. And a support rod is arranged and used for supporting the positioning plate. The lower end of the supporting rod is arranged under the positioning plate, so that the supporting rod can be prevented from occupying the space outside the positioning plate, and the occupied space of the whole structure is reduced; meanwhile, the lower parts of the supporting rods are bound and connected with each other, so that the three supporting rods form a plurality of triangular supporting structures, and the supporting stability is improved. And arranging an anchoring part for increasing the connecting effect between the foundation bolt and the concrete structure of the foundation. And a positioning hoop is arranged and used for supporting the foundation bolts, so that the shape surrounded by all the foundation bolts is kept unchanged. Set up the ejector pin for support anchor assembly, thereby realize supporting rag bolt, in order to guarantee that rag bolt's the elevation of upper end meets the requirements.

During the use, pass the locating hole on the locating plate with rag bolt's upper end, then place whole built-in fitting structure in pre-buried position, then fix a position the horizontal position of locating plate, simultaneously, still need fix a position the position of locating hole on the locating plate to guarantee that rag bolt's position accords with the installation requirement of steel-concrete combination post, come the elevation position of rag bolt upper end through the ejector pin at last and adjust, make rag bolt's upper end accord with the requirement of connecting. Through the support that sets up the locating plate and the bracing piece, make support and rag bolt form a whole to improve rag bolt's fixed strength, reduced rag bolt and taken place the possibility of displacement, simultaneously, when the installation, only need to be fixed bracing piece and ejector pin can, made things convenient for the installation.

Furthermore, a cylinder with a sealed lower end is arranged in the middle of the positioning plate and detachably connected with the support. Through setting up the drum, utilize the drum to form a recess of placing the shear key of steel-concrete composite post lower extreme after concrete placement, need not the damaged fluting operation of later stage carrying out the concrete, improved the installation effectiveness of steel-concrete composite post.

Furthermore, the downside fixedly connected with of locating plate has the gag lever post of three at least slope settings, and all gag lever posts are the annular permutation and distribute along the axis of locating plate, and the lower extreme ligature of all gag lever posts is connected. Through setting up the gag lever post, make many gag lever posts form the support to the drum lower extreme to make things convenient for the drum to fix a position.

Furthermore, a pull rope is connected between the upper end of the cylinder and the limiting rod. Through setting up the stay cord, fix the upper end and the gag lever post of drum through the stay cord, only need during the dismantlement to cut the stay cord and can accomplish the separation of drum and gag lever post to conveniently carry out the connection and the dismantlement of drum.

Further, the lower end of the cylinder is provided with a clamping groove which is in concave-convex fit with the limiting rod. Through setting up the draw-in groove, make the lower extreme card of drum on the gag lever post and be difficult for taking place to slide, guaranteed the accuracy of drum position.

Further, the upper end cover of rag bolt is equipped with the protective sheath. Through setting up the protective sheath, avoided rag bolt's upper end screw thread position to glue the concrete and lead to inconvenient coupling nut.

Furthermore, a through groove extending along the axial direction of the cylinder is arranged on the side wall of the cylinder. Through setting up logical groove, when conveniently need take out the drum behind concreting, lead to the groove and can become a weak position on the lateral wall of drum, then, break off the lateral wall of drum along leading to the groove to the convenience is taken out the drum, convenient operation.

Further, the anchoring piece is a rectangular plate, and the surface of the rectangular plate is perpendicular to the foundation bolt. The face of rectangular plate is perpendicular with rag bolt, and when making the rectangular plate anchor in the concrete, rag bolt can not take place to rotate, simultaneously, need not to consider the position state of anchor board when installation rag bolt, has made things convenient for the installation.

Further, the protective sleeve is an elastic rubber sleeve. The rubber sleeve can be mounted and separated from the foundation bolt by elastic deformation, so that the operation is convenient.

Further, a sealing plate is detachably connected to the top of the cylinder. After the sealing plate is arranged, the phenomenon that the cylinder is taken out due to the influence of concrete is avoided because the concrete flows into the cylinder and is solidified to support the inside of the cylinder when the concrete is poured.

Drawings

Fig. 1 is a schematic structural diagram of a first embodiment of the structure of the embedded part of the reinforced concrete composite column of the present invention.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: foundation bolt 1, drum 2, locating plate 3, gag lever post 4, location hoop 5, bracing piece 6, anchor assembly 7, ejector pin 8.

The first embodiment is as follows: as shown in figure 1: the embedded part structure of the steel-concrete combined column comprises a bracket and ten foundation bolts 1.
