Description

Technical Field

[0001] The invention relates to the field of prefabricated assembled reinforced concrete structures, and in particular to a prefabricated concrete assembled structure with a ribbed formwork structure and a construction method thereof. Background Art

[0002] The existing prefabricated and assembled structural system is mainly composed of prefabricated shear walls, prefabricated composite slabs, prefabricated composite beams and other prefabricated components. After the prefabricated components are hoisted and positioned and the steel bars are arranged and tied, the prefabricated components are post-cast and superimposed, and the sleeve grouting and steel bar connection are carried out to form an overall structure. The existing prefabricated superimposed system requires a large amount of on-site wet work in the post-casting superimposition process, and also requires the support and demolding of the casting formwork on the outdoor side corresponding to the component connection part. At the same time, in order to reduce the disturbance of the prefabricated components during the hoisting and post-casting superimposition process, a large number of vertical supports are required to support and protect the components.

As needed, a multi-layer structure can be formed from top to bottom by multiple structural units.

When specifically connected, the first prefabricated shear wall 4 can be connected with the second prefabricated shear wall 5 to form an L-shaped shear wall combination structure, and the two L-shaped shear wall combination structures are arranged to face each other at intervals, which is convenient for setting up the first prefabricated concrete composite beam 1, the second prefabricated concrete composite beam 2, and the full prefabricated concrete slab 3 above, and the width of the first prefabricated shear wall 4 can be smaller than the width of the second prefabricated shear wall 5, but these schemes can be appropriately changed and are not used to limit the present invention.

[0039] In addition, the lower end of the first prefabricated shear wall 4 and the lower end of the second prefabricated shear wall 5 are respectively provided with a plurality of downwardly protruding support members, which can be specifically in the form of support short columns 11 or other appropriate structures, and the support members can be pre-buried in the prefabricated components, or can be positioned and installed on site, as permanent support and positioning components of the prefabricated shear walls during hoisting and positioning. Of course, the tops of the first prefabricated shear wall 4 and the second prefabricated shear wall 5 can also be provided with a wall rib formwork structure 21 and a rib formwork structure end plate 22 for local post-casting and superposition.

[0041] As a specific structural example of the first precast concrete composite beam 1 and the second precast concrete composite beam 2 (not limiting the present invention), the first precast concrete composite beam 1 and the second precast concrete composite beam 2 each include a beam body 13, a protruding beam rib formwork structure 14 arranged above the beam body 13, and a plurality of stirrups 15, the beam rib formwork structure 14 is located outwardly relative to the upper shear wall to form a stop with the upper surface of the beam body 13, the stirrups 15 are located inwardly relative to the upper shear wall, and the transverse ends of the beam body 13 are also respectively provided with protruding end support members 16 (such as precast beam ox-bearing plates) and connecting longitudinal reinforcements 17.

[0042] According to a specific embodiment of the present invention, the bottom of the fully precast concrete slab 3 has a slab bottom rib formwork structure 18 protruding outward. The slab bottom rib formwork structure 18 is arranged here to facilitate the pouring of high-performance concrete, complete the local post-casting connection between the precast components, and also ensure that an effective vibration working space is provided for the vibrating equipment during the pouring process, thereby improving the pouring quality and effectively exerting the connection performance between the components.

The precast slab stress-bearing steel bars 19 and slab end support teeth 20 at the connection between the fully precast concrete slab 3 and the beam body 13 extend above the retaining platform. More specifically, in the case of at least two fully precast concrete slabs 3, the extension length of the precast slab stress-bearing steel bars 19 on the side where they are spliced ​​with the fully precast concrete slab 3 is consistent with the extension width of the slab bottom rib formwork structure 18, and are staggered with the precast slab stress-bearing steel bars 19 of the adjacent components; the extension length of the precast slab stress-bearing steel bars 19 on the side where they are spliced ​​with the shear wall (beam) extends to the center line of the shear wall (beam), but the present invention is not limited thereto. The fully precast concrete slab 3 can be either a solid slab or a hollow slab; at the same time, the functional use of the fully precast concrete slab 3 is not limited, and it can also be used for horizontal slabs such as bay window slabs, air conditioning slabs, and balcony slabs.

[0043] In addition, the present invention also provides a construction method for the above-mentioned precast concrete assembled structure with ribbed formwork structure, the construction method comprising the steps of:

[0044] a. See Figure 7 and Figure 8 For ease of understanding, the assembly of two groups of shear wall combination structures is completed, wherein the assembly of each group of shear wall combination structures includes: hoisting and positioning the second prefabricated shear wall 5, and after completing the assembly and fixation, assembling the first prefabricated shear wall 4 with the second prefabricated shear wall 5, wherein the first connecting steel bar 8 of the first prefabricated shear wall 4 needs to be extended into the vertical groove 9 of the second prefabricated shear wall 5, and after completing the assembly and fixation of the first prefabricated shear wall 4 with the second prefabricated shear wall 5, the connection between the first prefabricated shear wall 4 and the second prefabricated shear wall 5 is sealed for the component gap, so as to facilitate the subsequent pouring of high-performance concrete, and realize the dislocation mutual anchor connection between the vertical connecting steel bars of the prefabricated shear walls;

[0045] b. See Figure 1 and Figure 8For ease of understanding, the hoisting and positioning of the precast concrete composite beam is performed: the first precast concrete composite beam 1 and the second precast concrete composite beam 2 are hoisted and dropped horizontally, so that one lateral end of the first precast concrete composite beam 1 is supported in the first upper opening groove 6 in the first group of shear wall composite structures, and the other lateral end of the first precast concrete composite beam 1 is supported in the second upper opening groove 7 in the second group of shear wall composite structures, and one lateral end of the second precast concrete composite beam 2 is supported in the second upper opening groove 7 in the first group of shear wall composite structures, and the other lateral end of the first precast concrete composite beam 1 is supported in the first upper opening groove 6 in the second group of shear wall composite structures, wherein the end support member 16 (which can be a precast ox-carrying board) of the beam body 13 is ensured to fall into the corresponding upper opening groove (the first upper opening groove 6 or the second opening groove). This step can realize the rapid positioning and assembly of the precast concrete composite beam, form an effective member support, and greatly reduce the number of lower supports of the precast concrete composite beam;

[0046] c. See Figure 1 and Fig. 9 For ease of understanding, the hoisting and positioning of the full precast concrete slab 3 is performed: the full precast concrete slab 3 is hoisted and dropped horizontally, and the hoisting and dropping is performed on the upper shear wall. Specifically, the plate end support teeth 20 can be dropped and placed on the precast shear wall (specifically the first precast shear wall 4 and the second precast shear wall 5) or the precast composite beam (specifically the first precast concrete composite beam 1 and the second precast concrete composite beam 2), so as to realize the rapid positioning and assembly of the full precast concrete slab 3, form an effective component support, and there is no need to set up the lower support of the full precast concrete slab 3 on site;

[0047] d. See Figure 6 and Fig. 9 For ease of understanding, the post-casting superposition connection process of the connection parts is performed after the assembly of one structural unit is completed (specifically, the assembly of the first precast shear wall 4 and the second precast shear wall 5 in each group of shear wall composite structures in one structural unit, as well as the first precast concrete composite beam 1, the second precast concrete composite beam 2, and the full precast concrete slab 3 is completed), or the post-casting superposition connection process of the connection parts is performed after the assembly of multiple structural units is completed. For example, the present invention can design only one layer of structural units as needed, or it can be as follows Figure 6The post-casting superposition connection process of the upper and lower two-layer structural units shown, or even more layers of structural units, can be specifically the process of wall-to-wall (e.g., the first precast shear wall 4 and the second precast shear wall 5), wall-to-beam (e.g., the first precast shear wall 4 and the first precast concrete superposition beam 1), wall-to-slab (e.g., the first precast shear wall 4 and the full precast concrete slab 3), beam-to-slab (e.g., the first precast concrete superposition beam 1 and the full precast concrete slab 3), slab-to-slab (the full precast concrete slab 3 and the full precast concrete slab 3) and other connection parts, which are processed by the process of high-performance concrete 23 steel bar non-contact lap local post-casting technology, to achieve a prefabricated structure fast construction solution with no steel sleeve connection, no casting formwork, less on-site wet work, and easy construction operation. Of course, for multiple structural units, the post-casting superposition connection process of the connection part can be carried out after the assembly of one structural unit is completed, and then the assembly of the next (layer) structural unit and the post-casting superposition connection process of the subsequent connection parts can be carried out. When the construction process is reasonable and complies with relevant regulations, the operation sequence is reasonably adjusted.
