Description

Technical Field

[0001] This utility model belongs to the field of building technology, and relates to new building industrialization, and in particular to an assembled composite frame structure building. Background Technology

[0002] For multi-story office buildings and school buildings, the main structure often adopts a reinforced concrete frame structure. When using the prefabricated modular construction method, the building is often divided into prefabricated frame module units according to the rooms. The prefabricated frame module units are prefabricated as a whole in the factory, and multiple prefabricated frame module units are assembled into a whole building on the construction site along the vertical and horizontal directions. However, the existing prefabricated frame module units have the following technical problems:

[0003] First, pressure grouting is required to connect the vertical reinforcement bars of the upper and lower columns. Pressure grouting is complicated to operate and difficult to control the grouting quality. In addition, the grouting holes and grout outlets are exposed on the column surface, which affects the interior decoration effect.

[0004] Second, the floor slabs are made of composite floor slabs or fully prefabricated floor slabs. Composite floor slabs have low stiffness and are prone to cracking, and the interior floor decoration cannot be completed in the factory in advance. Fully prefabricated floor slabs have high stiffness and the interior floor decoration can be completed in the factory in advance, but the overall building floor slab after assembly has poor in-plane stiffness.

[0005] Third, adjacent beams of adjacent modules on the same floor are only connected by a composite layer, which results in a weak connection and the floor slab at the connection point is easily damaged under earthquake action. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model proposes an assembled composite frame structure building, which can avoid one or more of the problems of the prior art, such as the complexity of pressure grouting operation, the conflict between connection construction and interior decoration, and the poor connection strength between modules.

[0007] Some embodiments of this utility model provide an assembled composite frame structure building, which is assembled from multiple prefabricated frame module units along the horizontal and vertical directions. The prefabricated frame module unit includes columns, beams, and a top slab. Vertical reinforcement bars that participate in structural stress are provided in the columns along the vertical direction. The vertical reinforcement bars of the upper and lower prefabricated frame module units are connected by grouting sleeves. The grouting sleeves are located at the upper end of the vertical reinforcement bars and have an opening at the upper end. The lower end of the vertical reinforcement bar of the upper prefabricated frame module unit is inserted into the grouting sleeve at the upper end of the vertical reinforcement bar of the lower prefabricated frame module unit. An installation joint is provided between the columns of the upper and lower prefabricated frame module units.

[0008] Optionally, the grouting sleeve is a semi-grouting sleeve, with the lower end of the grouting sleeve connected to the column vertical reinforcement of the lower precast frame module unit by a thread, and the upper part of the grouting sleeve connected to the column vertical reinforcement of the upper precast frame module unit by a high-strength grouting material.

[0009] Specifically, the lower end of the grouting sleeve is inside the column of the precast frame module unit, and the upper end of the grouting sleeve extends 5 to 100 mm beyond the top surface of the column of the precast frame module unit.

[0010] In some embodiments, the column vertical reinforcement of the prefabricated frame module unit extends directly from the bottom surface of the column of the prefabricated frame module unit.

[0011] In some embodiments, the column vertical reinforcement of the precast frame module unit does not extend directly from the bottom surface of the column of the precast frame module unit. Instead, the lower end of the column vertical reinforcement of the precast frame module unit is connected to a splicing sleeve near the bottom surface of the column of the precast frame module unit. The bottom surface of the splicing sleeve is flush with the bottom surface of the column. The column vertical reinforcement is spliced ​​and extended through the splicing sleeve and inserted into the grouting sleeve at the upper end of the column vertical reinforcement of the lower precast frame module unit.

[0012] In some embodiments, beams are provided around the top slab, the central area of ​​the top slab is prefabricated as a whole along the thickness direction of the top slab, a post-cast strip is provided within a width range of 200-600mm between the top slab and the beam, and the thickness of the prefabricated part of the top slab below the post-cast strip is 40-100mm.

[0013] In some embodiments, the beam is a composite beam, and the precast portions of adjacent beams of the precast frame module unit are provided with multiple post-cast holes. One end of the post-cast hole is on the side of the precast portion of the beam, and the other end is on the top surface of the precast portion of the beam. The post-cast holes of the beams of adjacent precast frame module units correspond one-to-one. Shear reinforcement is inserted into the post-cast holes, and the shear reinforcement passes through the post-cast holes of the beams of adjacent precast frame module units. After the post-cast concrete is poured, a connection structure is formed between the beams of adjacent precast frame module units.

[0014] In some embodiments, post-cast holes are provided at the top of adjacent columns of precast frame module units. One end of the post-cast hole is on the side of the column and the other end is on the top surface of the column. The post-cast holes of the columns of adjacent precast frame module units correspond one-to-one. Shear reinforcement is inserted into the post-cast holes and passes through the post-cast holes of the columns of adjacent precast frame module units. After the post-cast concrete is poured, a connection structure is formed between the columns of adjacent precast frame module units.

[0015] Specifically, the top surface of the precast concrete of the column in the precast frame module unit is flush with the top surface of the composite layer of the beam; or the top surface of the precast concrete of the column in the precast frame module unit is flush with the top surface of the precast concrete of the beam, and the part above the top surface of the precast concrete of the column is cast as a whole with the composite layer of the beam.

[0016] Specifically, when the height of the installation joint is 10-30mm, the installation joint is filled with grout; when the height of the installation joint is greater than 30mm, the column has a through vertical hole along the height direction, and post-cast concrete is poured through the vertical hole, and the installation joint is filled with post-cast concrete.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) The column vertical reinforcement of this utility model adopts grouting sleeve connection and the upper end of the grouting sleeve is open. The column vertical reinforcement can be connected without pressure grouting. The connection operation is simple, the quality is easy to control, and the allowable error is large.

[0019] (2) When installing the prefabricated frame module unit of this utility model, the alignment operation of the column vertical bars and the grouting sleeve is carried out near the lower top plate, which does not require high-altitude alignment and has high hoisting safety.

[0020] (3) The top slab of this utility model is provided with a composite post-pouring strip around it, which can take into account the advantages of the high rigidity of the fully precast floor slab and the good connection performance of the composite floor slab, and avoid the disadvantages of using fully precast floor slabs or composite floor slabs alone.

[0021] (4) The prefabricated parts of adjacent prefabricated frame module unit beams of this utility model are connected by shear reinforcement, avoiding the connection of adjacent beams only through the composite layer, and the connection strength of adjacent beams is good.

[0035] Embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While some embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0036] Unless otherwise stated, the technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; other experimental methods and technical means not specifically mentioned herein refer to experimental methods and technical means commonly used by one of ordinary skill in the art.

[0037] This invention provides an assembled composite frame structure building that enables rapid on-site construction of the building through multiple prefabricated frame module units, avoiding the drawbacks of existing technologies such as complex pressure grouting operations, conflicts between connection construction and interior decoration, and poor connection strength between modules.

[0038] refer to Figures 1-5This utility model describes an assembled composite frame structure building, which is assembled from multiple prefabricated frame module units 1 along the horizontal and vertical directions. Each prefabricated frame module unit 1 includes columns 2, beams 3, and a top plate 4. Vertical reinforcement bars 21 that participate in structural stress are provided in the columns 2 along the vertical direction. The vertical reinforcement bars 21 of the upper and lower prefabricated frame module units 1 are connected by grouting sleeves 22. The grouting sleeves 22 are located at the upper end of the vertical reinforcement bars 21 and have an opening at the upper end. The lower end of the vertical reinforcement bars 21 of the upper prefabricated frame module unit 12 is inserted into the grouting sleeve 22 at the upper end of the vertical reinforcement bars 21 of the lower prefabricated frame module unit 11. An installation joint 5 is provided between the columns 2 of the upper and lower prefabricated frame module units 1.

[0039] Preferably, the grouting sleeve 22 is a semi-grouting sleeve, with the lower end of the grouting sleeve 22 connected to the column vertical reinforcement 21 of the lower precast frame module unit 11 by a thread, and the upper part of the grouting sleeve 22 connected to the column vertical reinforcement 21 of the upper precast frame module unit 12 by a high-strength grouting material.

[0040] The lower end of the grouting sleeve 22 is inside the column 2 of the precast frame module unit 1, and the upper end of the grouting sleeve 22 extends out of the top surface of the column 2 of the precast frame module unit 1 by a length of 5 to 100 mm.

[0041] In the description of this utility model, it should be noted that the terms "upper layer", "lower layer", "upper end", "lower end", "top surface", "bottom surface", and "below" are based on the usual orientation or positional relationship when the assembled composite frame structure of this utility model is used. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] Example 1:

[0043] refer to Figures 1-3 The vertical reinforcement 21 of the precast frame module unit 1 extends directly from the bottom surface of the column 2 of the precast frame module unit 1. For example... Figure 3 As shown, the lower end of the column vertical reinforcement 21 of the upper precast frame module unit 12 extends directly from the bottom surface of the column 2 of the upper precast frame module unit 12 and is inserted into the grouting sleeve 22 at the upper end of the column vertical reinforcement 21 of the lower precast frame module unit 11. The grouting sleeve 22 is a semi-grouting sleeve. The lower end of the grouting sleeve 22 is connected to the column vertical reinforcement 21 of the lower precast frame module unit 11 by a thread, and the upper part of the grouting sleeve 22 is connected to the column vertical reinforcement 21 of the upper precast frame module unit 12 by a high-strength grouting material. An installation joint 5 is provided between the column 2 of the lower precast frame module unit 11 and the upper precast frame module unit 12. The height of the installation joint 5 is 10-30mm, and the installation joint 5 is filled with grouting material.

[0044] The working principle of this embodiment is as follows: During on-site construction, the lower precast frame module unit 11 is installed first. The upper end of the grouting sleeve 22 is open, and the mixed high-strength grout is poured into the grouting sleeve 22 through the upper end opening. The grout is then spread on the top surface of the column 2 of the lower precast frame module unit 11. Then, the upper precast frame module unit 12 is hoisted. The lower end of the column vertical reinforcement 21 of the upper precast frame module unit 12 is naturally inserted into the grouting sleeve 22 into which the high-strength grout has been poured. The length of the column vertical reinforcement 21 inserted into the grouting sleeve 22 meets the requirements of the current national standard. Generally speaking, the length of the column vertical reinforcement 21 inserted into the grouting sleeve 22 is not less than eight times the diameter of the column vertical reinforcement 21. After the upper precast frame module unit 12 is installed in place, the grout that was previously spread on the top surface of the column 2 of the lower precast frame module unit 11 is compacted under the action of extrusion, so as to achieve dense filling of the grout in the installation joint 5.

[0045] This solves the first technical problem mentioned in the background technology. By setting the grouting sleeve 22 on the upper end of the column vertical reinforcement 21 of the lower precast frame module unit 11, with the opening of the grouting sleeve 22 facing upwards, the mixed high-strength grout can be manually poured into the grouting sleeve 22 through the upper opening. Under the premise of achieving the connection of the column vertical reinforcement 21 with the grouting sleeve, the complex construction process of sealing and pressure grouting of the existing grouting sleeve connection is avoided, which greatly reduces the grouting construction requirements. The grouting quality can be visually inspected and controlled. Moreover, the grouting sleeve 22 does not need to be set with special grouting holes and grout outlet holes, and there is no situation where the grouting holes and grout outlet holes are exposed on the column surface. This avoids the grouting holes and grout outlet holes affecting the interior decoration effect, which meets the needs of the prefabricated frame structure building to integrate interior decoration in the factory.

[0046] Meanwhile, the allowable alignment error between the grouting sleeve 22 and the column vertical reinforcement 21 is generally not less than 10mm. The large allowable error results in high installation efficiency. The alignment operation between the column vertical reinforcement 21 and the grouting sleeve 22 is carried out near the top plate 4 of the lower precast frame module unit 11. Construction personnel can complete the alignment of the column vertical reinforcement 21 and the grouting sleeve 22 on the top plate 4 of the lower precast frame module unit 11 without the need for high-altitude alignment. Construction personnel do not need to be exposed to the precast frame module at high altitude for a long time, resulting in high hoisting safety.

[0047] Example 2:

[0048] refer to Figure 4The column vertical reinforcement 21 of the precast frame module unit 1 does not extend directly from the bottom surface of the column 2 of the precast frame module unit 1. A connecting sleeve 23 is connected to the lower end of the column vertical reinforcement 21 near the bottom surface of the column 2 of the precast frame module unit 1. The bottom surface of the connecting sleeve 23 is flush with the bottom surface of the column 2. The column vertical reinforcement 21 is connected to an extended reinforcing bar 24 via the connecting sleeve 23 and inserted into the grouting sleeve 22 at the upper end of the column vertical reinforcement 21 of the lower precast frame module unit 11. Preferably, the connecting sleeve 23 is a straight thread sleeve, which is currently widely used in the construction field. The column vertical reinforcement 21 and the extended reinforcing bar 24 are connected to the straight thread sleeve via threaded connections, and the tension and compression between the column vertical reinforcement 21 and the extended reinforcing bar 24 are transmitted through the straight thread sleeve.

[0049] The working principle of this embodiment two is as follows: During the production of the prefabricated frame module unit 1, a splice sleeve 23 is pre-installed. The extension steel bars 24 are not connected during the factory transportation process. Before hoisting at the construction site, the extension steel bars 24 are screwed into the splice sleeve 23, and then the prefabricated frame module unit 1 is hoisted. Compared to embodiment one, in embodiment two, the column vertical reinforcement 21 of the prefabricated frame module unit 1 does not directly extend from the bottom surface of the column 2 of the prefabricated frame module unit 1. This avoids interference with the extended portion of the column vertical reinforcement 21 during transportation, facilitating the protection of the finished product.

[0050] Example 3:

[0051] refer to Figures 5-7 The precast frame module unit 1 includes columns 2, beams 3 and a top slab 4. The top slab 4 is surrounded by beams 3. The central area of ​​the top slab 4 is precast as a whole along the thickness direction of the top slab 4. A post-cast strip 6 is set within a width range of 200-600mm between the top slab 4 and the beams 3. The thickness of the precast part of the top slab 4 below the post-cast strip 6 is 40-100mm. That is to say, the central area of ​​the top slab 4 is a fully precast slab with a composite layer around it. The beams 3 are composite beams. The post-cast strip 6 around the top slab 4 and the composite layer of the adjacent beams 3 are cast at the same time. This solves the second technical problem mentioned in the background technology. The middle area of ​​the top slab 4, which is the main area, adopts a fully prefabricated structure, which can ensure the overall rigidity of the top slab 4 and avoid cracking. The fully prefabricated area can complete the interior floor tile laying, water and electricity decoration work in the factory in advance, reducing the amount of decoration work on the construction site and shortening the overall construction period. At the same time, the perimeter of the top slab 4 adopts a composite structure and is equipped with a post-pouring strip 6. The post-pouring strip 6 of the adjacent prefabricated frame module unit 1 is cast at the same time as the composite layer of the beam 3, thus forming a continuous post-pouring area between adjacent prefabricated frame module units 1. This can achieve the same in-plane rigidity of the overall building floor slab as the traditional cast-in-place floor slab. The top slab 4 of this utility model has the advantages of both the high rigidity of the fully prefabricated slab and the good in-plane rigidity of the composite floor slab.

[0052] See Figures 5-7Beam 3 is a composite beam, meaning it consists of a lower precast section and an upper composite layer. The precast section is prefabricated in the factory, while the composite layer is poured with concrete on-site. Adjacent precast beams 3 of adjacent precast frame module units 1 have multiple post-cast holes 7. One end of each post-cast hole 7 is on the side of the precast section of beam 3, and the other end is on the top surface of the precast section of beam 3; that is, the post-cast hole 7 extends through the side and top surfaces of the precast section of beam 3. Preferably, metal pipes are pre-embedded during the production of the precast frame module unit 1 to form the post-cast holes 7. The post-cast holes 7 can have a circular cross-section with a diameter not less than 100mm, and the spacing of the post-cast holes 7 along the length of beam 3 is 500–2000mm. (Reference) Figure 7 The post-cast holes 7 of beams 3 in adjacent precast frame module units 1 correspond one-to-one. After hoisting, shear reinforcement 8 is inserted into the post-cast holes 7. The shear reinforcement 8 passes through the post-cast holes 7 of beams 3 in adjacent precast frame module units 1. During construction, the post-cast concrete in the post-cast holes 7 is poured simultaneously with the pouring of the composite layer post-cast concrete of beams 3. After the post-cast concrete is poured, a connection structure is formed between beams 3 of adjacent precast frame module units 1. The beams 3 of adjacent precast frame module units 1 are connected through the post-cast concrete in the post-cast holes 7 and the shear reinforcement 8. This solves the third technical problem mentioned in the background technology: adjacent beams 3 of adjacent precast frame module units 1 on the same floor are not only connected at the top through the composite layer of beams 3, but also on the sides of beams 3 through the post-cast concrete and shear reinforcement 8 penetrating through the post-cast holes 7, which improves the connection strength of adjacent beams 3 and thus avoids concentrated damage to the floor slab at the connection of adjacent precast frame module units 1 under earthquake action.

[0053] refer to Figure 5 Post-cast holes 7 are provided at the top of adjacent columns 2 of precast frame module unit 1. The construction of post-cast holes 7 on columns 2 is basically the same as that on beams 3. One end of the post-cast hole 7 on column 2 is on the side of column 2, and the other end is on the top surface of column 2. The post-cast holes 7 of columns 2 of adjacent precast frame module units 1 correspond one-to-one. After hoisting, shear reinforcement 8 is inserted into the post-cast hole 7. The shear reinforcement 8 passes through the post-cast hole 7 of the column 2 of the adjacent precast frame module unit 1. After the post-cast concrete is poured, a connection structure is formed between the columns 2 of the adjacent precast frame module units 1. In particular, as shown in the figure... Figure 5 As shown, the top surface of the precast concrete of column 2 is flush with the top surface of the composite layer of beam 3.

[0054] Example 4:

[0055] refer to Figure 8 , Figure 9The top surface of the precast concrete of column 2 of precast frame module unit 1 is flush with the top surface of the precast concrete of beam 3. The composite reinforcement of beam 3 can be installed after the precast frame module unit 1 is produced. During the pouring of post-concrete on the construction site, the part above the top surface of the precast concrete of column 2 and the composite layer of beam 3 are poured as a whole.

[0056] Example 5:

[0057] See Figure 10 , Figure 11 When the height of the installation joint 5 between the columns 2 of the lower precast frame module unit 11 and the upper precast frame module unit 12 is greater than 30mm, the installation joint 5 cannot be filled with grout. Therefore, a through-hole 25 is provided in the column 2 along the height direction. Post-cast concrete is poured through the column vertical hole 25 on site, thus filling the installation joint 5 with post-cast concrete. Specifically, during the production of the precast frame module unit 1, a corrugated metal pipe is pre-embedded in the column 2 to form the column vertical hole 25. To ensure the quality of the post-cast concrete, the cross-sectional dimension of the column vertical hole 25 should not be less than 100mm, ensuring sufficient space for concrete vibration during the pouring process.

[0058] In summary, this utility model avoids the complex operations of pressure grouting, such as sealing and pressure grouting, by optimizing the arrangement of the grouting sleeves, reducing the difficulty of connection construction, improving the quality of connection construction, and avoiding the impact of the grouting sleeves on interior decoration; the innovative top slab structure, with a composite layer set around the top slab, solves the problems of in-plane stiffness difference of the fully precast slab and the conflict between the composite floor slab and the interior floor decoration; and the connection structure formed on the side of the beam greatly improves the connection strength of adjacent modular beams.
