Description

Technical Field

[0001] The utility model relates to the technical field of steel beam construction devices, in particular to a two-support-one-fixed steel beam construction structure. Background Art

[0002] The current application status of steel cantilever beams in the construction field shows a diversified development trend, including the increased application of high-strength, earthquake-resistant, fire-resistant and weather-resistant steel plates and H-shaped steels. With the increasing requirements for the yield strength of construction steel, the use of high-strength structural steel has become a trend, aiming to reduce the deadweight of building structures and meet the stress requirements of special and complex structures. At the same time, in order to meet the needs of earthquake resistance, steel should have a low yield strength ratio, high plastic deformation capacity and plastic energy dissipation capacity, thereby improving the ductility of the overall structure and increasing the safety margin of the building steel structure under seismic loads. In addition, in order to ensure welding quality and simplify the welding process, it is required to further improve the weldability of construction steel and develop thick steel plates that do not require preheating welding or have a low preheating temperature, such as ultra-low carbon bainitic non-quenched and tempered TS750MPa grade thick high-strength steel plates. When the thickness t≥75mm, no preheating is required during welding.

[0003] However, the traditional steel beam construction device cannot meet people's needs, and it has the following defects: First, there is no new type of steel beam construction device designed. For the steel cantilever beam used in normal working conditions, the bearing capacity is poor, and the bayonet beam of the cantilever part needs to be structurally verified and processed, which causes trouble for engineering and technical personnel in structural verification and may cause structural design errors; second, there is no simple device body designed. For the steel cantilever beam used in normal working conditions, the complicated structure requires the use of a large number of material components to realize the function of the device, and at the same time causes some steel beam structure designs to be relatively unreasonable, resulting in waste of some materials, which does not meet the purpose of "saving materials", and the installation difficulty coefficient is relatively high, and it is impossible to effectively ensure the safety and construction period goals. Summary of the Invention

[0004] The purpose of the utility model is to provide a two-supported and one-fixed steel beam construction structure to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A two-support and one-solid steel beam construction structure includes an indoor panel, a main beam is fixedly connected to the outer wall of one side of the indoor panel, a balcony panel is fixedly connected to the outer wall of one side of the main beam, and the balcony panel is fixedly connected to the outer wall of one side of the indoor panel, an I-beam is fixedly connected to the upper surface of the indoor panel, an indoor inner steel wire rope and an indoor outer steel wire rope are fixedly connected to the outer wall of one side of the I-beam, and one end of the indoor inner steel wire rope and the indoor outer steel wire rope are fixedly connected to the outer wall of one side of the indoor panel, an balcony inner steel wire rope and a balcony outer steel wire rope are fixedly connected to the outer wall of one side of the I-beam, and one end of the balcony inner steel wire rope and the balcony outer steel wire rope are fixedly connected to the outer wall of one side of the balcony panel.

[0007] As a further technical solution of the present invention, a mounting groove is provided on the upper surface of the I-beam, and a vertical pole is sleeved on the upper surface of the mounting groove.

[0008] As a further technical solution of the present invention, an inner short cross bar and an inner long cross bar are provided on the outer wall of one side of the vertical pole, a hanging ring is sleeved on the outer wall of one side of the inner short cross bar, and the inner long cross bar is sleeved on the outer wall of one side of the hanging ring.

[0009] As a further technical solution of the present invention, an outer long horizontal bar and a short balcony horizontal bar are provided on one side outer wall of the vertical pole, and the outer long horizontal bar and the short balcony horizontal bar are both sleeved on one side outer wall of the hanging ring.

[0010] As a further technical solution of the present invention, a positioning groove is opened on the outer wall of one side of the indoor panel, and the upper surface of the positioning groove is sleeved with a rear end U-shaped steel bar anchor ring, and the rear end U-shaped steel bar anchor ring is sleeved on the outer wall of one side of the I-beam.

[0011] As a further technical solution of the present invention, the upper surface of the positioning groove is sleeved with a first front end U-shaped steel bar anchor ring and a second front end U-shaped steel bar anchor ring, and the first front end U-shaped steel bar anchor ring and the second front end U-shaped steel bar anchor ring are sleeved on one side outer wall of the I-beam.

[0012] As a further technical solution of the present invention, a reinforcing rib is fixedly connected to the outer wall of one side of the indoor panel, and the reinforcing rib is fixedly connected to the outer wall of one side of the main beam.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention is designed with a two-support and one-fixed steel beam construction structure. Compared with the steel cantilever beam under normal working conditions, only one inclined steel wire rope is added, and the bearing capacity is greatly improved, and there is no need to perform structural verification and processing on the bayonet beam of the cantilever part, which solves the troubles of a considerable number of engineering and technical personnel in structural verification, and meets the "material saving" requirements of green construction; at the same time, a device body with a simple structure is designed. On the premise of meeting the function of the device, due to the more reasonable stress form of the I-beam structure, under the action of the same load, there is no need to increase the length of the anchor end and increase the cross-sectional size, thereby achieving the purpose of "material saving", and due to the reduction of the dead weight of the I-beam, in addition to saving costs, it also reduces the difficulty coefficient of installation, which can more effectively ensure the realization of safety and construction period goals.

The first front end U-shaped steel bar anchor ring 7 and the second front end U-shaped steel bar anchor ring 8 are matched with the rear end U-shaped steel bar anchor ring 9 to prevent the horizontal rotation of the steel beam. They can be regarded as embedded supports and do not participate in the force calculation; a reinforcing rib 14 is fixedly connected to the outer wall of one side of the indoor panel 1, and the reinforcing rib 14 is fixedly connected to the outer wall of one side of the main beam 3. The reinforcing rib 14 is used to strengthen the connection between the indoor panel 1, the balcony panel 2 and the main beam 3.

[0023] Working principle: When using the utility model, first assemble the device. The plane layout of the steel beam should be carried out according to the plane layout of the upper frame. Set the I-beam 4 on the indoor plate 1 to be erected. Fix the I-beam 4 through the positioning groove 6, the first front end U-shaped steel bar anchor ring 7, the second front end U-shaped steel bar anchor ring 8 and the rear end U-shaped steel bar anchor ring 9. The I-beam 4 is a steel beam with a height of not less than 160mm. The support point and the tie point of the I-beam 4 should be set on the stable main structure main beam 3 and should be reliably connected. The U-shaped steel bar anchor is straight. The diameter should not be less than 18mm. The function of the front and rear anchor rings is to prevent the horizontal rotation of the steel beam. They can be regarded as embedded supports and do not participate in the force calculation. The U-shaped anchor ring must be buried on the main load-bearing member of the main structure, and in order to allow the upper position of the scaffolding pole 10, the U-shaped anchor ring can be staggered 200~300mm from the plane position of the steel beam.

The design value of the lateral force should be calculated according to the formula based on the height of the cantilever scaffolding segmented erection, and the larger one should be taken. After the calculation is completed, the inner short crossbar 11, the outer long crossbar 12, the inner long crossbar 13 and the balcony short crossbar 15 are laid on the vertical pole 10 according to the calculated distance, and they are fixed by the ring 18.

After the wire rope is connected and adjusted to meet the requirements, the support structure of the segmented scaffolding is inspected and accepted. Only after the acceptance is qualified can subsequent work be carried out. Before the wire rope is set, the force system is not fully formed, and the scaffolding is erected at a height that only meets the edge protection requirements. At the same time, no other loads shall be applied to the scaffolding. Only after the inner wire rope is connected and an effective force system is formed can the support system of this part be removed. The mounting groove 5 is used to install the vertical pole 10, and the reinforcement rib 14 is used to strengthen the connection between the indoor panel 1, the balcony panel 2 and the main beam 3.
