Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and examples. The implementation of the utility model includes but not limited to the following examples.

Example

As shown in Figures 1 to 4, a reinforced concrete frame structure includes a prefabricated column 1 and a prefabricated beam 2 connected to the prefabricated column by a bolt 8 at one end; square steel pipes are pre-embedded in the prefabricated column, and Bolt holes for bolts to pass through the prefabricated column are provided on the column; an I-beam 3 is pre-embedded in the middle of one end of the prefabricated beam connected to the prefabricated column, and an upper section above the I-beam is pre-embedded on the prefabricated beam. The longitudinal reinforcement 4 is pre-embedded with the lower longitudinal reinforcement 5 located under the I-beam on the prefabricated beam, and the end of the prefabricated beam connected with the prefabricated column is provided with the I-beam, the upper longitudinal reinforcement and the lower longitudinal reinforcement. A square end plate 6 with welded ribs; the square end plate is provided with through holes corresponding to the bolt holes; the bolts pass through the bolt holes and through holes to fix the prefabricated columns and prefabricated beams. With the frame structure of the utility model, the prefabricated columns and prefabricated beams are fixed by bolts, without welding the two, and without on-site wet work, thereby reducing environmental pollution, and the operation is very simple and the stability is also extremely strong. In actual operation, since the square end plate is welded with the I-beam, the upper longitudinal reinforcement and the lower longitudinal reinforcement, the stability between the square end plate and the prefabricated beam is ensured, and then the square end plate and the prefabricated column are connected by bolts. Fixed, because the square steel pipe is pre-embedded in the prefabricated column, so that the bolt can remain stable when passing through the prefabricated column and will not shift. The square end plate is fixed to the prefabricated column by multiple bolts, thus ensuring the stability between the prefabricated beam and the prefabricated column. In addition, for practical use, the middle longitudinal reinforcement located on both sides of the I-beam can also be pre-embedded on the prefabricated beam, and the middle longitudinal reinforcement is also welded with the square end plate, which further improves the performance of the utility model. stability. Yet this utility adopts components such as I-beam, upper longitudinal rib and lower longitudinal rib in order to reduce cost on the premise of ensuring stability.

In order to strengthen the stability of the prefabricated beam, two rows of shear studs 7 are arranged on the top of the I-beam. By arranging the anti-shear studs, the shock resistance of the utility model is better.

In order to better realize the utility model, each side of the prefabricated column is provided with ten bolt holes, which are divided into four rows from top to bottom, the middle two rows are two bolt holes, and the remaining two rows are three bolt holes ; The square end plate is provided with ten through holes corresponding to the bolt holes, in other words, the through holes are located around the end of the prefabricated beam, so that when the bolts are installed, there is enough room for operation, and Prefabricated beams located in the middle of the square end plate can also improve the stability of the whole utility model, and fixed points (bolts) are arranged around the ends of the upper prefabricated beams, thereby greatly improving the stability of the utility model. It is worth noting that, in order to further improve the anti-seismic performance of the utility model, corresponding bolt holes and through holes can also be added. In addition, when all bolts pass through the prefabricated column, the horizontal and vertical bolts are all misplaced.

In order to facilitate welding, one end of the I-beam, the upper longitudinal reinforcement and the lower longitudinal reinforcement extends to the outside of the prefabricated beam and connects with the square end plate. In the actual production process, the I-beam, the upper longitudinal reinforcement and the lower longitudinal reinforcement all extend to a section outside the prefabricated beam, and the extended part is used for welding with the square end plate, which leaves room for operation and makes welding more convenient.

It is worth noting that the structure of the utility model includes a "ten" shape, a "T" shape, a "one" shape, and an "L" shape. That is to say, four, three, two, or one prefabricated beams can be arranged on the side of the prefabricated column.

According to above-mentioned embodiment, just can realize the utility model well. It is worth noting that, based on the premise of the above-mentioned structural design, in order to solve the same technical problem, even if some insubstantial changes or embellishments are made on the utility model, the essence of the technical solution adopted is still the same as that of the utility model. same, so it should also be within the protection scope of the present utility model.
