Pre-buried channel steel connecting member

The invention relates to a pre-buried channel steel connecting member, in particular to a pre-buried member.

In the prior art, the pre-buried members used in the engineering construction are mostly steel members, and the connecting holes are arranged on the steel members; according to the use, the steel members with different cross-sections are selected. Anchors and/or bolts can be fixed at the connecting holes of the embedded members. Although the embedded members are simple in structure, the holes are easily blocked by concrete and fail in the construction of the concrete. In addition, the existing embedded components have no corresponding buffering members, the overall bearing capacity of the embedded components is weak, and the mechanical properties are poor; and the number of connecting holes provided on the existing embedded components is limited, and the scope of use is limited; The components and the bolts are connected by welding, the construction operation is inconvenient, and the positioning cannot be accurately performed, and the use form is relatively simple, which seriously reduces the application range of the embedded device.

Based on the above scheme, as shown in FIG. 1 and FIG. 2, the embedded members are all C-shaped channel steels with an open downward direction, and the longitudinal groove sides of the C-shaped channel steel may also have reinforcing ribs and embedded members. It can also be a combination of L-shaped steel and C-shaped channel steel, and the L-shaped steel is fixed to the back of the C-shaped channel steel.

Therefore, the steel connection makes the bent portion of the pre-buried steel body very easy to be broken by the external force, so that it does not function as a load bearing, or does not function as a bearing force.

The purpose of the present invention is to provide a pre-buried channel steel connecting member with simple structure, good bearing capacity and convenient construction.

In order to solve the above problems and achieve the object of the present invention, the technical means of the present invention is realized by providing a pre-buried channel connecting member as a pre-buried connecting member in the building structure, including a C-shaped channel with an opening downward. The C-shaped channel has a row of equidistant and discontinuous slots on the back, and the C-shaped channel has an inwardly-folded opening, wherein the C-channel has a pre-buried steel body a pre-embedded steel body having a positioning hole corresponding to the position of the slot, the pre-buried A flexible sheet is disposed between the steel body and the C-shaped channel steel, and the embedded steel body, the flexible sheet and the C-shaped channel steel are sequentially connected by bolts and nuts to form a back-to-back connection structure, and the The flexible sheet is closely attached between the embedded steel body and the C-shaped channel steel. The novel not only overcomes the situation that the connecting hole on the embedded component is blocked, but also the back-to-back connection structure improves the bearing force, and the welding operation is not required during the on-site lifting installation, which simplifies the operation steps and facilitates the construction.

Before the pre-burial, the new type is installed according to the following steps: firstly laying plastic film or plastic gasket on the back of the C-shaped channel steel; placing the embedded steel body on the plastic film or plastic gasket, and pre-burying the steel body The positioning holes on the upper surface are aligned with the slots on the C-shaped channel steel; the bolts are inserted from the direction of the embedded steel body, and the positioning holes of the steel body are pre-buried, penetrate the plastic film or the plastic gasket, and finally from the C-shaped groove. The slot in the steel is pierced and locked by a nut.

Based on the above solution, in order to improve the waterproof function, the flexible sheet is one of the following: a plastic film and a plastic gasket.

Based on the above solution, the pre-buried steel body is one of the following: a steel sheet, a C-shaped member, and an L-shaped member.

Based on the above solution, the pre-buried steel body is a C-shaped member and is disposed in the same direction as the C-shaped channel steel. The width of the C-shaped member is the same as that of the C-shaped channel steel, and the length is not greater than the C-shaped channel steel. If it is equal to the length of the C-shaped channel steel, or is smaller than the length of the C-shaped channel steel, the sub-sections are arranged on the back surface of the C-shaped channel steel.

Based on the above solution, the pre-buried steel body is a C-shaped member and is disposed perpendicular to the C-shaped channel steel, and the length of the C-shaped member is not less than the width of the C-shaped channel steel.

Based on the above solution, the C-shaped channel steel has a rectangular open frame shape with each side perpendicular to each other, or the open side is an isosceles trapezoidal cross section of the short side.

Further, in order to strengthen the bearing capacity, when the C-shaped channel steel is an isosceles trapezoidal cross section whose short side is a short side, the side wall is further provided with a reinforcing rib.

Based on the above solution, the L-shaped member is an L-shaped steel sheet or a C-shaped steel sheet, and is fixed to the back of the C-shaped channel steel.

Compared with the prior art, the advantages of the present invention are as follows: First point: in the hoisting construction, no welding or punching operation is required, and the operation is convenient.

Second point: plastic film or plastic gasket effectively prevents slots and fasteners from being cast Concrete is clogged.

The third point: the overall bearing capacity of the embedded steel body is strong.
