Description

Technical Field

[0001] The utility model belongs to the technical field of construction, and in particular relates to a frame hollow core tube structure. Background Art

[0002] The core tube is the central part of the building, enclosed by the elevator shaft, staircases, ventilation shafts, cable shafts, public restrooms, and some equipment rooms. Together with the outer frame, it forms an outer-frame inner-tube structure, cast with reinforced concrete. This structure is highly effective in balancing structural forces and offers excellent earthquake resistance.

[0003] Since the conventional frame hollow core tube structure uses screws to connect the steel structure, the screws need to be tightened little by little, and the screws need to bear gravity, so many screws need to be operated, which makes the conventional frame hollow core tube structure difficult to assemble.

[0004] To this end, we proposed a frame hollow core tube structure to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the conventional frame hollow core tube structure is difficult to assemble, and to propose a frame hollow core tube structure.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A frame hollow core tube structure includes a steel column, a steel rod mounted on the steel column, and steel bolts inserted into the steel column and the steel rod. During use, the steel rod is first mounted on the steel column, and after the steel column and steel rod are aligned, the steel bolt is inserted into the steel rod. The steel bolt is then hammered into the steel column using the expansion force of the steel bolt on the interior of the steel column to secure the steel column and the steel rod to the steel column via the steel bolt. This improves installation convenience compared to conventional bolt assembly methods.

[0008] Preferably, the steel column comprises a column body, a restraining post, and a socket, wherein the restraining post and the socket are fixedly connected to the outer periphery of the column body. A steel rod is placed on the socket, and a steel bolt is passed through the steel rod. The lower portion of the steel bolt is nailed into the socket, and the restraining post restrains the upper portion of the steel bolt. The restraining post and the socket facilitate fixing the upper and lower portions of the steel bolt.

[0009] Preferably, the steel column further comprises a guide rod, which is fixedly connected to the corner of the column body, so as to facilitate the alignment of the steel rod and the socket.

[0010] Preferably, the steel column further comprises a reinforcement plate, which is fixedly connected between the column and the socket, so as to increase the structural stability between the socket and the column.

[0011] Preferably, the steel rod comprises a rod body, and the side end of the rod body is hollowed out and provided with a through hole. A steel bolt is passed through the through hole and nailed into the socket, and the rod body is stabilized on the socket by the steel bolt, and the socket bears the main downward force of the rod body, thereby ensuring the stability of the steel rod.

[0012] Preferably, the steel bolt includes a clamping plate and an insertion rod, wherein the insertion rod is symmetrically fixedly connected to the lower portion of the clamping plate. The insertion rod is inserted into the through hole and then knocked downward to insert the insertion rod into the socket. At the same time, the insertion rod drives the clamping plate into the restraining pile, so that the clamping plate is firmly fixed to the restraining pile, thereby facilitating the installation of the steel bolt.

[0013] Preferably, the steel bolt further comprises a knocking block, which is fixedly connected to the upper end of the insertion rod. Knocking the knocking block causes the knocking block to act downward on the insertion rod, thereby facilitating the knocking operation of the steel bolt.

[0014] In summary, the technical effects and advantages of the utility model are:

[0015] 1. When using, first place the steel rod on the steel column, align the steel column and the steel rod, insert the steel bolt into the steel rod, and then use a hammer to nail the steel bolt into the steel column. Use the expansion force of the steel bolt on the inside of the steel column to fix the steel column and fix the steel rod to the steel column through the steel bolt. Compared with the conventional bolt assembly method, the installation convenience is improved.

[0016] 2. Place the steel rod on the socket, then pass the steel bolt through the steel rod, nail the lower part of the steel bolt into the socket, restrain the upper part of the steel bolt through the restraint pile, and fix the upper and lower parts of the steel bolt conveniently through the restraint pile and the socket.

[0017] 3. Pass the steel bolt through the hole and nail it into the socket. Use the steel bolt to stabilize the rod on the socket. Use the socket to bear the main downward force of the rod to ensure the stability of the steel rod.

[0018] 4. Insert the rod into the through hole, then knock the rod downward to insert the rod into the socket. At the same time, use the rod to drive the clamping plate into the restraining pile so that the clamping plate is firmly clamped on the restraining pile, which is convenient for installing the steel bolt.
