Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a structure of a steel building.

[0002]

2. Description of the Related Art In the conventional general reinforced concrete or steel frame reinforced concrete building, as shown in FIG. 1, a concrete template A is formed between upper and lower horizontal beams 10 by wires or nails, and two front and rear templates are formed. The concrete 11 is filled between A, and after the concrete 11 is hardened, the template A is removed.

[0003]

However, the conventional structure of a steel-framed concrete building or a steel-framed reinforced concrete building has the following drawbacks at the time of construction. (1) During the construction of steel-framed reinforced concrete, it is not easy to arrange the reinforcing bars of the reinforced concrete, and it is not easy to connect with the steel frame, and because the concrete often surrounds the reinforcing bars to support the stress, the bondability is poor and the reliability is high. There is a problem with the structure, and it seriously affects the structural safety of the building.

(2) During the construction of steel reinforced concrete, it is not easy to combine the templates, and foreign matters on the templates and scraps generated when binding with wires or hammering nails into the concrete. In addition to falling and mixing, affecting the quality of the concrete, it may also pierce water or electrical pipes when piercing, which causes water to leak and destroy the hardened concrete for repair. I have to repair it.

(3) During the construction of steel-framed reinforced concrete, the gap between the steel frame, the reinforcing bars and the template in the structure is narrow, which increases the difficulty in pouring and striking the concrete. The state of the honeycomb (a state where hollow holes are generated by the air when pouring concrete) cannot be detected in advance because it is poured into, and it cannot be immediately improved, so that a structure with incomplete coating is easily formed.

(4) During construction of steel-framed reinforced concrete, structural materials such as wall pillars are too high, and it is not easy to open the concrete pouring port in the template (certain standard). It occurs and shrinks after hardening, affecting the quality of concrete. (5) During the construction of steel-framed reinforced concrete, the construction of the structure includes processes such as steel frame, rebar, template and concrete pouring, so there are many construction points and there are problems such as procurement and management of workers necessary for construction. Yes, it is difficult to secure the quality of the process.

(6) During the construction of steel-framed reinforced concrete, it is necessary to store a considerable amount of space for reinforcing bars, templates and supporting materials, which obstructs the passage of workers and the smooth progress of construction work, which imposes the burden of environmental management on site. To increase. (7) During the construction of steel-framed reinforced concrete, the wooden template forms a space into which the concrete is poured, so the wooden template is easily corroded, has a short service life, and is suitable for temporary work. With materials, there is no benefit in strengthening the structure, and resources are wasted. In addition, the operation of materials is a waste of forest resources.

(8) The basic principle of the steel-framed reinforced concrete structure is that the two parts of the steel frame and the reinforced concrete are joined and integrated, and they jointly support the external force. However, the contact surfaces of the two are prone to cracking due to poor joints, and the reinforced concrete part has its structure when the number of reinforced concrete arrangements is insufficient, when an earthquake occurs, or when a shock is given by an external force. Material deforms significantly and tears open or bursts. If it is light, the internal conduit is destroyed and water leaks,
In severe cases, it affects the safety of the structure.

(9) The pipes (PVC plastic pipes) buried in the walls are apt to crack due to earthquakes or sunlight when the walls on both sides of the pipeline are too thin, and when it rains, water will enter the room. It causes the phenomenon of seeping. Therefore, an object of the present invention is to provide a steel-framed reinforced concrete structure in which the entire structural system is stable, the toughness is increased, an earthquake can be sufficiently endured, and the load due to the weight of the wall can be reduced.

[0010]

According to the means of the present invention for solving the above-mentioned problems, the steel frame structure has main steel frames of columns and cross beams, and a supporting frame and reinforcing bars are provided in the middle of the main steel frames. The reinforcing structure having the above is assembled, and a flow hole for pouring concrete is formed on the surface of the supporting frame. next,
In the floor iron structure, the floor iron plate is arranged on the upper surface of the main steel frame of the cross beam, and the reinforcing steel nets are installed on the floor iron plate. Multiple connectors are attached to the main steel frame of the horizontal beam, and a screw hole is formed on one side of this connector.The screw hole corresponds to the connecting tool provided on the main steel frame of the horizontal beam, and is connected by bolts and nuts. Both are firmly connected. The wall structure is connected to a connecting tool provided on the main steel frame of the horizontal beam. The mesh plate is fixed so as to surround the outer periphery of the iron material structure assembled to the steel frame structure, and is used as an outer mesh.

In the steel reinforced concrete structure of the present invention, the effect of concrete restraint is strengthened by the steel frame structure including columns and cross beams and the reinforcing structure, and the strength of the structure is increased, and each floor has a steel plate on the upper surface of the cross beam. Since the reinforcing bar nets are arranged in an interlocking arrangement on it, the strength is strong.In addition, the external wall structure and the internal partition wall structure are connected to each other by various connecting members, so the earthquake Strong resistance to. Moreover, since each structure is constructed at the factory and then transported to the construction site, the work site is not crowded. In addition, since the concrete pouring work is performed at once after the entire structure is constructed, the construction can be completed quickly.

[0023]

The present invention has the following effects. (1) Since the connecting tool, pillar and beam structure auxiliary support frame, wall structure support frame, mesh plate, and each connecting member can be processed and produced in the factory, the construction is quick, the quality is stable, the efficiency is high,
The purpose of automatic production can be achieved. Under normal circumstances, the construction of the present invention can shorten the construction period by one-half or two-thirds compared with the general method, and save interest expense.

(2) The connecting member is welded on the channel and the angle member, and is fixedly connected to the column-beam structure and the supporting frame of the wall structure with bolts and nuts, so that the concrete and the channel and the angle member are rigid. In addition, it improves the seismic resistance of the structure as well as improving the defect of poor joint between the steel frame, the reinforcing bar and the concrete contact surface of the longitudinal steel frame reinforced concrete building.

(3) The mesh plate can be used in place of the template, and is fixed to the support frame with a mesh sealer to proceed to integrally connect the steel frame, the support frame and the mesh plate. Furthermore, the mesh plate has a high toughness and completely binds the concrete in the mesh plate,
Concrete does not easily tear open or burst in the event of an earthquake or shock. (4) Since the auxiliary structure surrounding the pillars and beams and the wall structure are made up of channels or horizontal frame-type support frames, automatic production is possible and the construction is quick and high quality. Moreover, the strength of the entire support frame is superior to the conventional binding bar method and more stable.

(5) Since the mesh plate substitutes the template,
The pillars and walls are clearly visible from the outside. Therefore, it often occurred when binding the conventional template with wires,
There is no danger of opening a hole in the pipe, and it is possible to open an opening or a concrete pouring hole at any time, and it is clear at a glance whether or not there is a honeycomb state in the concrete, and the actual condition of pouring can be easily understood.

(6) Since the mesh plate can be used as a substitute for the template, it is easy to install, and there is no template scrap or foreign matter attached to the template, and there are no wires or hanging rods that support the template. No auxiliary construction equipment is required. Therefore, the working space is large and it is not necessary to store the templates in a large space, so the environment of the construction site is clean, does not excessively use wood,
Do not waste forest resources.

(7) The design concept of the present invention mainly uses a steel frame and a supporting frame of a horizontal frame type to assist the reinforcing bars and concrete, and the construction is mainly a factory production, and is a combination of construction site, concrete injection and finishing. It is a structure that consists of a supporting frame and a mesh plate that supports the bolts and nuts and connecting parts of each type, and the connection is reliable. Quality is guaranteed.

(8) Since the mesh plate is used as a substitute for the template, the bubbles generated in the concrete pouring escape to the outside from the holes of the mesh plate. In addition, concrete becomes tighter if you tap it lightly without putting too much force, at the same time there is no beehive that has occurred in conventional building construction by filling the holes in the mesh plate, and the phenomenon of floating water does not occur and concrete solidification No need to remove the template after curing, the wall surface is flat and the surface finish is easy. In addition, the contact surface of the rough mesh plate stabilizes the paste cement when it is applied, and the wall surface does not crack easily.

(9) Assembling a wall on the outside of the structure of the upper and lower floors,
After the concrete is hardened, the wall structure is connected to the fixed reinforcing bar of the floor and the floor plate, and is connected to the connector and the steel frame structure by a connector, and the wall structure forms one supporting wall. Light concrete is poured into the mesh plate of the isolation wall structure for room isolation to reduce the load on the components. (10) When burying PVC plastic pipe in the wall,
Since it is protected by a mesh plate on the outside of the wall, even if both side walls of the pipe are relatively thin, cracks will not occur due to an earthquake or sunlight irradiation.

(11) After all the wall structures of the building have been assembled, concrete is injected into each floor, so that workers can enter the site and complete the construction at one time. In addition, the phenomenon that the wall assembling worker and the concrete worker have to alternately enter the construction site and wait for another work does not occur. (12) For water and electricity pipes, after assembling each support frame, connect the pipes and insert them, and there is no need to make holes in the template for the case, etc. You can see through the boards and inspect the pipes for accuracy at any time, and test the pipes for water leaks before pouring concrete.
