Description

Technical Field

[0001] The utility model relates to the field of assembled buildings, and in particular to an installation structure of a composite plate and a main beam. Background Art

[0002] In the process of prefabricated construction, the main beam is usually cast in place, while the floor slab uses prefabricated composite slabs. In order to make the connection between the beam and slab more stable, beard bars are usually reserved at the edge of the composite slab. Before pouring the main beam concrete, the beard bars are inserted between the steel bars of the main beam to combine the steel bars of the beam and slab together. Figure 1 shown.

[0003] However, the composite slab is usually installed and positioned by hoisting. However, during the lowering process of the composite slab, the beard ribs are likely to interfere with the upper longitudinal main ribs of the main beam, making it impossible to install it in place. Therefore, the beard ribs are usually bent in advance to avoid the position of the upper longitudinal main ribs. After the composite slab is installed in place, the beard ribs are straightened and inserted under the upper longitudinal main ribs.

[0004] However, this operation of moving the beard tendon back and forth can easily reduce the strength of the beard tendon, and it is difficult to return the beard tendon to its original state. This is inconsistent with the design and can easily lead to uncontrollable hidden dangers. Utility Model Content

[0005] The utility model aims to provide an installation structure for a composite plate and a main beam, which does not require bending of ribs and can ensure the connection between the beam and the plate.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: an installation structure of a composite plate and a main beam, including a main beam and a composite plate, a plurality of beard bars are provided on the side of the composite plate close to the main beam, the main beam includes closed stirrups and upper longitudinal main bars, the hooks of the closed stirrups are arranged at the bottom, the upper longitudinal main bars pass through the upper part of the closed stirrups, and the height of the beard bars is lower than the upper longitudinal main bars.

[0007] The beneficial effects of this program are:

[0008] 1. In the prior art, since the bottom of the beam sinks compared to the floor slab, to facilitate the tying of the main beam reinforcement, the hooks of the closed stirrups are usually left at the top for easier operation. However, in this solution, to avoid interference between the upper longitudinal main reinforcement and the beard reinforcement, when tying the main beam reinforcement, the portion other than the upper longitudinal main reinforcement is tied first, and then the composite slab is installed, so that the beard reinforcement is inserted between adjacent closed stirrups. The upper longitudinal main reinforcement is then passed through all the closed stirrups from the end of the main beam in sequence, while the upper longitudinal main reinforcement is positioned above the beard reinforcement. Finally, the upper longitudinal main reinforcement and the closed stirrups are tied together.

[0009] However, when the upper longitudinal main reinforcement passes through the closed stirrups, the hooks of the closed stirrups easily hinder the horizontal movement of the upper longitudinal main reinforcement. Therefore, in this solution, the hooks of the closed stirrups are placed at the bottom to ensure smooth horizontal movement of the upper longitudinal main reinforcement. Since the hooks are not convenient to operate at the bottom, it is necessary to tie the closed stirrups and the lower longitudinal main reinforcement in an open area in advance, and then place the closed stirrups and the lower longitudinal main reinforcement in the position of the main beam.

[0010] 2. The beard reinforcement can serve as a temporary support when the upper longitudinal main reinforcement moves horizontally, so that the upper longitudinal main reinforcement is closer to the upper side of the closed stirrup after moving into place, so as to facilitate the binding of the upper longitudinal main reinforcement and the upper side of the closed stirrup.

[0011] Furthermore, the ends of the beard ribs are bent upwards, and the beard ribs are used to support the upper longitudinal main ribs.

[0012] Furthermore, temporary supports are provided between adjacent closed stirrups, and both ends of the temporary supports are supported on the composite plates on both sides of the closed stirrups respectively. The middle of the temporary support is lower than the upper longitudinal main reinforcement, the height of the middle of the temporary support is lower than the upper longitudinal main reinforcement, and the middle of the temporary support is higher than the beard reinforcement.

[0013] Furthermore, the temporary support is a bent steel bar.

[0014] Furthermore, the temporary support is a bent steel plate.

[0015] This solution also has the following effects:

[0016] 1. When the upper longitudinal main reinforcement moves horizontally, it needs to be supported by the beard reinforcement. However, the upper longitudinal main reinforcement is prone to sliding and falling along the length of the beard reinforcement. Therefore, in this solution, the end of the beard reinforcement is bent in advance to prevent the upper longitudinal main reinforcement from sliding and falling.

[0017] 2. During the horizontal movement of the upper longitudinal main reinforcement, the pressure on the beard reinforcement can easily cause the beard reinforcement to deform, affecting the depth of the beard reinforcement embedded in the main beam, thereby affecting the connection effect of the beam and slab; in this solution, a temporary bracket is set up to support the upper longitudinal main reinforcement instead of the beard reinforcement, thus avoiding the deformation of the beard reinforcement; after completing the binding of the closed stirrups and the upper longitudinal main reinforcement, the temporary bracket is removed.

[0018] 3. To facilitate the placement and removal of the temporary support, the temporary support is made of a steel bar, with both ends supported on the composite plates on both sides. When the upper longitudinal main reinforcement is tied, it will be lifted up slightly to facilitate connection with the upper side of the closed stirrups, and then the end of the temporary support can be pulled out.
