Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a modular stirrup and a construction method thereof. Background Art

[0002] Floor slabs in construction projects are typically equipped with bottom reinforcement and surface reinforcement. Surface reinforcement refers to the steel bars installed near the surface of the slab to resist the negative bending moment of the slab. As a force-bearing reinforcement, its position cannot be changed arbitrarily and must be constructed according to the positions marked on the drawings. However, during the reinforcement construction process, it is inevitable that people will step on the surface reinforcement of the slab. Therefore, construction workers usually install stirrups in the slab to support the surface reinforcement and prevent it from shifting and deforming, but this is not very effective. Another method is to lay independent long stirrup channels on the floor slab. The treads of these long stirrup channels are slightly higher than the finished surface of the floor slab. Construction workers can walk and work on the channels without directly stepping on the floor slab reinforcement, which effectively prevents the floor slab reinforcement from being displaced and deformed, and improves the quality of steel bar construction. However, the floor slabs in different areas of the building have different sizes. If you want to use long stirrup channels, you must first customize each floor slab, and then configure long stirrup channels of matching sizes for each floor slab, which greatly reduces the efficiency of making and installing the long stirrup channels. In addition, the shape of the long stirrup channels is usually rectangular. When encountering floor slab structures other than rectangles, it is difficult to lay them out, and its applicability is low. Summary of the Invention

However, it should be noted that many of the details listed in this specification are merely provided to help the reader gain a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be practiced even without these specific details.

[0033] like Figure 1-2 As shown, a modular stirrup includes a first steel bar column 101, a first steel pipe column 102, a first steel bar folding beam 103, a first connecting crossbeam 104, and a supporting panel 105. The first steel bar column 101 is vertically arranged, and two are spaced apart on the left and right; two first steel bar folding beams 103 are horizontally arranged in front and back, and the rear ends of the two first steel bar folding beams 103 are fixedly connected to the upper parts of the front sides of the two first steel bar columns 101, and the front ends are tilted and bent downward; the first steel pipe column 102 is vertically arranged, and two are spaced apart on the left and right, and the rear sides of the two first steel pipe columns 102 are fixedly connected to the front ends of the two first steel bar folding beams 103, respectively. The interior of the first steel pipe column 102 is vertically passed through, and its inner diameter is larger than the diameter of the first steel bar column 101, so that The first steel column 101 of the rear stirrup module can be inserted into the first steel pipe column 102 of the front stirrup module, and the height of the first steel pipe column 102 is lower than the first steel column 101, so that after the first steel column 101 is inserted into the steel pipe column, the heights of the two stirrup modules are flush, ensuring the flatness of the stirrup channel; the second connecting beam 201 is arranged horizontally on the left and right, and two are arranged at intervals in the front and back. The two ends of the second connecting beam 201 located on the rear side are fixedly connected to the opposite side of the two first steel columns 101, and the two ends of the second connecting beam 201 located on the front side are fixedly connected to the opposite side of the two first steel folding beams 103; the support panel 105 is horizontally arranged between the two first steel folding beams 103 and the two second connecting beams 201. Multiple stirrup modules can be connected and spliced ​​to each other through the first steel column 101 and the first steel pipe column 102 to form a long strip or arc-shaped stirrup channel.

[0034] The stirrup module further includes a first reinforcement beam 106, which is horizontally arranged with its ends fixedly connected to opposite sides of the two first steel pipe columns 102. The first reinforcement beam 106 is used to connect the two first steel pipe columns 102 and serves as a transition when the first steel bars 101 and the first steel pipe columns 102 of the stirrup modules are connected to each other.

[0035] The support panel 105 is a mesh structure. The mesh structure support panel 105 can prevent construction workers from falling, ensuring safety, and can also significantly reduce the weight of the stirrup module, making it easier to transport and install.

[0036] In a further embodiment, the first steel bar column 101, the first steel bar folded beam 103, the first connecting beam 104, and the first reinforcing beam 106 are all HRB400 grade threaded steel bars; and the first steel pipe column 102 is a Q235 grade round steel pipe.

[0037] In a further embodiment, the diameters of the first steel bar column 101, the first steel bar folded beam 103, the first connecting beam 104, and the first reinforcing beam 106 are all 16 mm; the outer diameter of the first steel pipe column 102 is 20 mm, the inner diameter is 18 mm, and the wall thickness is 1 mm.

[0038] It also includes a second connecting crossbeam 201, a second steel bar column 202, a second steel bar folding beam 203, and a second steel pipe column 204; the second connecting crossbeam 201 is horizontally arranged left and right, and two are spaced apart in front and back, and the right end thereof is fixedly connected to the left side of the first steel bar folding beam 103 on the left; the second steel bar column 202 is vertically arranged with two, and the upper right sides of the two second steel bar columns 202 are respectively fixedly connected to the left ends of the two second connecting crossbeams 201; the second steel bar folding beam 203 is horizontally arranged left and right, and two are spaced apart in the left and right, and the left end thereof is fixedly connected to the right side of the first steel bar folding beam 103 on the right , and its right end is tilted and bent downward; the second steel pipe column 204 is vertically provided with two, the left sides of the two second steel pipe columns 204 are fixedly connected to the right end of the second steel folding beam 203, the second steel pipe column 204 is vertically penetrated, and its inner diameter is larger than the diameter of the second steel column 202, so that the second steel column 202 of the latter stirrup module can be inserted into the second steel pipe column 204 of the previous stirrup module, and the height of the second steel pipe column 204 is lower than the second steel column 202, so that after the second steel column 202 is inserted into the steel pipe column, the height of the two stirrup modules is flush, ensuring the flatness of the stirrup channel. When encountering an L-shaped floor structure, multiple stirrup modules can be connected and spliced ​​together through the second steel column 202 and the second steel pipe column 204 to form an L-shaped stirrup channel.

[0039] The stirrup module further includes a second reinforcement beam 205, which is arranged horizontally front to back, with its ends fixedly connected to opposite sides of the two second steel pipe columns 204. The second reinforcement beam 205 is used to connect the two second steel pipe columns 204 and serves as a transition when the second steel bars 202 and second steel pipe columns 204 of the stirrup modules are connected to each other.

[0040] The angle between the front end of the first folded steel beam 103 and the right end of the second folded steel beam 203 and the ground is 45 degrees. Since the height of the steel pipe column is lower than the steel column, the steel pipe column and the steel column can be smoothly connected to each other through the inclined bend of the steel folded steel beam.

[0041] In a further embodiment, the second connecting beam 201, the second steel bar column 202, the second steel bar folded beam 203, the second steel pipe column 204, and the second reinforcing beam 205 are all HRB400 grade threaded steel bars; and the first steel pipe column 102 is a Q235 grade round steel pipe.

[0042] In a further embodiment, the second connecting beam 201, the second steel column 202, the second steel folded beam 203, the second steel pipe column 204, and the second reinforcing beam 205 all have a diameter of 16 mm; the second steel pipe column 204 has an outer diameter of 20 mm, an inner diameter of 18 mm, and a wall thickness of 1 mm.

[0043] A construction method for a modular stirrup comprises the following steps:

[0044] S1 stirrup module batch prefabrication: stirrup modules are customized according to the actual floor size, including the stirrup module height, front-to-back length, and left-to-right width.

[0045] S2 transport stirrup modules: transport and lift multiple stirrup modules to the construction site floor;

[0046] S3 Assemble stirrups: Figure 3 As shown, multiple stirrup modules are spliced ​​together according to the floor structure to form a stirrup channel; when the floor structure is a rectangular structure, the two first steel bar columns 101 of the latter stirrup module are inserted into the first steel pipe columns 102 of the previous stirrup module, and in this way, multiple stirrup modules are connected to each other to form a long stirrup channel;

[0047] like Figure 4 As shown, when the floor structure has an arc structure, one of the first steel bar columns 101 of the subsequent stirrup module is inserted into the first steel pipe column 102 on the same side of the previous stirrup module, and the subsequent stirrup module is rotated to form an angle with the previous stirrup module. According to the arc angle, multiple stirrup modules are connected to each other in this way to form an arc-shaped stirrup channel; at the same time, since the subsequent stirrup module is rotated to form an angle with the previous stirrup module, a gap will be generated between the subsequent stirrup module and the previous stirrup module. In order to prevent the construction workers from stepping on empty space due to the large gap, the number of stirrup modules can be increased during splicing to reduce the angle, thereby reducing the gap between the two stirrups to ensure safety;

[0048] like Figure 5-6As shown, when the floor structure has an L-shaped structure, the two second steel bars 202 of the rear stirrup module are inserted into the second steel pipe column 204 of the front stirrup module to form an L-shaped stirrup channel; at the same time, if there is an arc-shaped structure after the L-shaped structure, one of the second steel bars 202 of the rear stirrup module can be inserted into the second steel pipe column 204 on the same side of the front stirrup module, and the rear stirrup module is rotated to form an angle with the front stirrup module to form an arc-shaped stirrup channel;

[0049] S4 stirrup module recycling: multiple stirrup modules are removed and recycled before the initial setting of the concrete;

[0050] S5 Maintenance: Clean the concrete and debris from each stirrup module;

[0051] S6 turnover: the stirrups after maintenance are rotated to the next construction floor, and S3-S5 are repeated until the construction of all floors is completed.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
