As shown in figure 16, the reinforcing bar in prefabricated top layer beam is set a roof beam in place just curved including top layer frame negative moment of girder muscle 19, top-level boxes Square muscle 20, top layer frame beam stirrup 21, bean column node stirrup 17 and polyvinyl chloride pipe 18, top layer frame negative moment of girder muscle 19 and top Layer Vierendeel girder sagging moment muscle is oppositely arranged about 20, and top layer frame negative moment of girder muscle 19 and top-level boxes are set a roof beam in place on the outside of sagging moment muscle 20 Connected by the top layer frame beam stirrup 21 of parallel arrangement, top layer frame negative moment of girder muscle 19 and top-level boxes are set a roof beam in place sagging moment muscle 20 Both sides of edges be oppositely arranged polyvinyl chloride pipe 18, connected between the polyvinyl chloride pipe 18 being oppositely arranged by bean column node stirrup 17 Connect.Its manufacturing process is:Top layer frame negative moment of girder muscle 19 and top-level boxes sagging moment muscle 20 of setting a roof beam in place are bound in top-level boxes first Set a roof beam in place stirrup 21;Then polyvinyl chloride pipe 18, the center of polyvinyl chloride pipe 18 and prefabricated bottom are bound using bean column node stirrup 17 The center of layer column or prefabricated middle level column Reinforcement 4 is same, and the diameter of polyvinyl chloride pipe 18 is more than column longitudinal stress steel 4 diameter 1-2cm of muscle;Finally bean column node stirrup 17 and polyvinyl chloride pipe 18 are bound in top layer frame negative moment of girder muscle 19 and top Layer Vierendeel girder sagging moment muscle 20.
(6) as shown in Figure 19-Figure 20, the concrete structure and making of I-shaped column-wall connecting key and trough girder-wall connecting key Process is as follows:
The size of I-shaped column-wall connecting key 22 is determined by the size of column-wall built-in fitting (Fig. 1);
The size of the key foot of trough girder-wall connecting key 23 is identical with the size of beam-wall built-in fitting (Fig. 7) upper aperture 8;Groove profile The side of beam-wall connecting key 23 sets circular hole III 24, and when the purpose for setting circular hole III 24 is grouting, grouting material can pass through circular hole Flow to other positions.
The prefabricated completion in factory of above-mentioned prefabricated components, then transports to construction site and assembles, and specific hoisting process is as follows:
(1) assembling of prefabricated underlay column (Fig. 5) and the cast in situ concrete foundation beam (Figure 21) with beam-wall built-in fitting (Fig. 7) Process, is shown in Figure 21-Figure 23.
As shown in figure 21, the cast in situ concrete foundation beam with beam-wall built-in fitting (Fig. 7), its production method with it is common cast-in-place Foundation beam is identical, and only side sets beam-wall built-in fitting (Fig. 7) on it, and top 25 based on beam-ends, 25 set base at the top of basis Reinforcing bar 26 is stretched out at the top of plinth.
As shown in figure 22, during lifting, prefabricated underlay column (Fig. 5) is lifted on 25 at the top of basis, and ensures to stretch at the top of basis Go out reinforcing bar 26 to be inserted into the reinforced bar sleeve 3 of prefabricated underlay column (Fig. 5) bottom, be then in the milk in sleeve, complete prefabricated bottom The assembling of layer column (Fig. 5) and the cast in situ concrete foundation beam (Figure 21) with beam-wall built-in fitting, is shown in Figure 23.
(2) lifting of dry wall (Figure 12), is shown in Figure 24-Figure 25.
As shown in figure 24, dry wall (Figure 12) is lifted to the top of foundation beam (Figure 21), ensures that beam-wall on the downside of it is pre- Embedded part (Fig. 7), the beam-wall built-in fitting (Fig. 7) of column-wall built-in fitting (Fig. 1) of the left and right sides on the upside of foundation beam (Figure 21) It is in close contact with the column in prefabricated underlay column closure-wall built-in fitting (Fig. 1).Then by trough girder-wall connecting key 23 along Square hole 8 on beam-wall built-in fitting (Fig. 7) is inserted into, then I-shaped column-wall connecting key 22 is fixed between column-wall built-in fitting (Fig. 1) Gap in, complete dry wall (Figure 12) assembling, see Figure 25.
(3) lifting of prefabricated middle level beam (Figure 15), is shown in Figure 26-Figure 28.
Prefabricated middle level beam (Figure 15) is lifted on to the top (Figure 26) of prefabricated underlay column (Fig. 5), and ensures prefabricated underlay column Reinforcement 4 corresponds to the polyvinyl chloride pipe 18 in prefabricated middle level beam core node region, is noted into polyvinyl chloride pipe 18 Enter grouting material, see Figure 27;Finally pacify between the beam of prefabricated middle level beam (Figure 15) and dry wall (Figure 12)-wall built-in fitting (Fig. 7) Trough girder-wall connecting key 23 is filled, the lifting of prefabricated middle level beam (Figure 15) is completed, sees Figure 28.
(4) repeat the above process, completing other layers includes the lifting of top layer prefabricated components, sees Figure 29.
(5) each layer there are the junction of column-wall built-in fitting (Fig. 1) and beam-wall built-in fitting (Fig. 7) support bar template, And by glass cement or other materials, ensure that bar template is closely connected with precast concrete beam, column, shear wall.Then in bar Perfusion grouting material 27 in shape template, until grouting material is full of bar template inner prop-wall built-in fitting (Fig. 1), beam-wall built-in fitting (figure 7) and I-shaped column-wall connecting key 22 and trough girder-wall connecting key 23 of connection fixed thereto gap.Treat that grouting material solidifies Afterwards, bar template is removed, the connection of precast beam, column and shear wall is completed, sees Figure 30.
The result shows that the utility model assembly connection structure and method, has the clear and definite reliable, assembly of Path of Force Transfer simply, The advantages that construction quality is easily guaranteed that, particularly can be achieved at the same time the transmission of moment of flexure and shearing between each prefabricated components.
