Description

Combination method and structure of pre-assembled ground beam and pre-assembled column

A combination method and structure of pre-assembled beams and pre-assembled columns, in particular to a combination method and structure of pre-assembled beams and pre-assembled columns applied to ground beams and ground columns.

In a building structure, the most important thing is the erection structure of ground beams and pillars. In today's construction methods, the ground pillars are first erected, and then the ground beams are nested from above the pillars to the bottom to complete the erection of the structure. The erected ground column may be a pre-assembled column, and the pre-assembled column is pre-assembled by the main reinforcement, stirrups and tie reinforcements. Usually, the pre-assembled column is erected on the main bar at one end of the ground, and it has a foot-spreading structure at an angle to the ground. In addition, the loose-foot structure is used to allow the pre-assembled columns to be erected on the construction ground, and can also be used to adjust the inclination angle of the pre-assembled columns to the ground, thereby adjusting the erection angle of the building. However, because of the existence of the scattered foot structure, if the ground beam is installed first and then the ground column is erected, the outer foot structure of the ground column will hinder the setting of the ground column in the ground beam, making the process of combining the ground column and the ground beam only It is carried out by first erecting the ground pillar and then setting the ground beam. Therefore, only one of the ground beam and the ground column can be pre-assembled, which limits the speed and simplification of the construction process.

In addition, in the above structure, because the scattered foot structure outside the pillar is pressed under the ground beam, when an earthquake comes, the energy of the earthquake will be received from the pillar closest to the earthquake source and transferred to the ground beam, and then The ground beam is passed to the floor. However, the above-mentioned energy transfer method will make supporting buildings The pillars of the object are first impacted by the earthquake energy, which can easily damage the building structure. Therefore, it is a subject that really needs to be improved.

In view of this, the present invention discloses a pre-assembled ground beam and pre-assembled column combination method and its combined structure. This combination method includes the following steps: a pre-assembled ground beam preparation step, a positioning device setting step, a pre-assembled column pre-assembly step, a threading step, and a fixing step. Pre-assembled ground beam preparation step: prepare a pre-assembled ground beam, the pre-assembled ground beam includes a beam stirrup group consisting of a plurality of beam main reinforcements and a plurality of beam main reinforcements, and the pre-assembled ground beam has a target combination area. The target combination area is provided with a plurality of working ribs, and a column stirrup group whose spacing is fixed by the plurality of working ribs. The positioning device setting steps: a plurality of positioning devices are set in the target combination area of the pre-assembled ground beam, and each of the plurality of positioning devices has a penetration space. Pre-assembled column pre-assembly step: prepare a pre-assembled column, which has a pre-assembled pre-assembled section and a joint section to be combined with the aforementioned pre-assembled ground beam. This pre-assembly section is provided with a plurality of column main reinforcements, and another column stirrup group that binds the plurality of column main reinforcements. This joint section is provided with a plurality of column main bars extending from the pre-assembly section. Piercing steps: each column main reinforcement piercing through the joint section is in each corresponding piercing space. Fixing step: fix the pre-assembled ground beam to the target penetration depth of the pre-assembled column, and fix the plurality of column main reinforcements located in the joint section and the column stirrup group located in the target combination area to each other.

The combined structure of pre-assembled ground beams and pre-assembled columns includes pre-assembled ground beams and pre-assembled columns. The pre-assembled ground beam includes a plurality of main beams, a beam stirrup group that bundles the plurality of main beams, and has a target combination area. The pre-assembled column includes a plurality of column main bars and at least two column stirrup groups. The pre-assembled column has a pre-assembled segment that does not penetrate the target combination area and a combined segment that penetrates the target combination. The pre-assembled and combined sections of the main reinforcement of these columns are bound by different column stirrup groups. Pre-assembled column and pre-assembled When the ground beam is combined, the pre-assembled column does not penetrate the pre-assembled ground beam.

Compared with the prior art, the combination method and structure of the pre-assembled ground beams and pre-assembled columns of the present invention has the following advantages: 1. The present invention is to first erect the pre-assembled ground beams and then combine them with pre-assembled columns, so the present invention The invented pre-assembled column does not need to use an external foot structure, so the pre-assembled column and pre-assembled ground beam can be assembled in the pre-assembled factory first, and only the pre-assembled ground beam and pre-assembled column need to be combined at the work site , Thereby improving construction efficiency; 2. The pre-assembled column of the present invention does not penetrate the pre-assembled ground beam, so when an earthquake comes, the energy transfer of the earthquake will start from the pre-assembled ground beam that is closer to the earthquake source, and then the energy Passed to the pre-assembled columns, and then passed to the floor by the pre-assembled columns. This kind of energy transmission method will be the first to bear the brunt of the pre-assembled ground beam and the larger contact area with the seismic energy. Therefore, compared with the conventional ground pillar with an external foot structure, the pre-assembled ground beam and pre-assembled column of the present invention The structure of this invention has a better ability to disperse the seismic energy, thereby improving the earthquake-proof effect of the building; 3. The pre-assembled column of the present invention does not need to penetrate the ground beam as the conventional ground column using the externally dispersed foot structure, and only needs to be deeply pre-built Assemble the ground beam to the target depth and install T-head anchors, thereby reducing the amount of steel bars and saving costs.
