Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, and in particular relates to a modular stirrup. Background Technology
[0002] Floor slabs in building construction typically have bottom reinforcement and top reinforcement. Top reinforcement refers to the steel bars placed near the surface of the floor slab to resist the negative bending moment. As it is a type of load-bearing reinforcement, its position cannot be arbitrarily changed and must be constructed according to the locations marked on the drawings. However, during the reinforcement construction process, it is unavoidable for workers to step on the top reinforcement. Therefore, construction workers usually install stirrup reinforcement in the floor slab to support the top reinforcement and prevent it from shifting or deforming, but this method is not very effective. Another method is to lay independent long stirrup passages on the floor slab. The tread surface of these long stirrup passages is slightly higher than the finished floor surface, allowing construction workers to walk and work on them without directly stepping on the floor slab reinforcement. This effectively prevents the floor slab reinforcement from shifting or deforming, and improves the quality of reinforcement construction. However, the floor slab dimensions vary in different areas of the building. If long stirrup passages are to be used, each floor slab must be custom-made, and then long stirrup passages of the same size must be configured for each floor slab. This greatly reduces the efficiency of the fabrication and installation of long stirrup passages. Moreover, the shape of long stirrup passages is usually rectangular, which makes it difficult to lay them when encountering floor slab structures that are not rectangular, resulting in low applicability.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.
[0023] like Figure 1-2As shown, a modular stirrup includes a first reinforcing bar column 101, a first steel pipe column 102, a first reinforcing bar folded beam 103, a first connecting beam 104, and a support panel 105. The first reinforcing bar columns 101 are vertically arranged, with two columns spaced apart on the left and right. Two first reinforcing bar folded beams 103 are horizontally arranged front and rear, with their rear ends fixedly connected to the upper front sides of the two first reinforcing bar columns 101, and their front ends bent downwards. The first steel pipe columns 102 are vertically arranged, with two columns spaced apart on the left and right. The rear sides of the two first steel pipe columns 102 are fixedly connected to the front ends of the two first reinforcing bar folded beams 103, and the interior of the first steel pipe columns 102 is vertically continuous, with an inner diameter larger than that of the first reinforcing bar columns 101. The first steel reinforcement column 101 of the subsequent stirrup module can be inserted into the first steel pipe column 102 of the preceding stirrup module, and the height of the first steel pipe column 102 is lower than that of the first steel reinforcement column 101, so that after the first steel reinforcement column 101 is inserted into the steel pipe column, the heights of the two stirrup modules are level, ensuring the flatness of the stirrup channel; the first connecting beams 104 are set horizontally to the left and right, and two are spaced apart front and back. The two ends of the first connecting beam 104 on the rear side are fixedly connected to the opposite side of the two first steel reinforcement columns 101, and the two ends of the first connecting beam 104 on the front side are fixedly connected to the opposite side of the two first steel reinforcement folded beams 103; the support panel 105 is horizontally set between the two first steel reinforcement folded beams 103 and the two first connecting beams 104. Multiple stirrup modules can be connected and spliced together by the first steel reinforcement columns 101 and the first steel pipe columns 102 to form a long strip or arc-shaped stirrup channel.
[0024] It also includes a first reinforcing beam 106, which is horizontally arranged on both sides and its two ends are fixedly connected to the opposite side of the two first steel pipe columns 102. The first reinforcing beam 106 is used to connect the two first steel pipe columns 102, and at the same time, when the first steel bar columns 101 and the first steel pipe columns 102 of multiple stirrup modules are connected to each other, the first reinforcing beam 106 can play a transition role.
[0025] The support panel 105 has a mesh structure. The mesh structure support panel 105 can prevent construction workers from falling, ensuring safety, while also significantly reducing the weight of the stirrup module, facilitating transportation and installation.
[0026] In a further embodiment, the first reinforcing bar column 101, the first reinforcing bar folded beam 103, the first connecting beam 104, and the first reinforcing beam 106 are all HRB400 grade threaded steel bars; the first steel pipe column 102 is a Q235 grade round steel pipe.
[0027] 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 16mm; the outer diameter of the first steel pipe column 102 is 20mm, the inner diameter is 18mm, and the wall thickness is 1mm.
[0028] It also includes a second connecting beam 201, a second reinforcing bar column 202, a second reinforcing bar folded beam 203, and a second steel pipe column 204; the second connecting beam 201 is horizontally arranged left and right, with two spaced apart front and back, and its right end is fixedly connected to the left side of the first reinforcing bar folded beam 103 on the left; two second reinforcing bar columns 202 are vertically arranged, and the upper part of the right side of the two second reinforcing bar columns 202 is fixedly connected to the left end of the two second connecting beams 201 respectively; the second reinforcing bar folded beam 203 is horizontally arranged left and right, with two spaced apart on the left and right, and its left end is fixedly connected to the right side of the first reinforcing bar folded beam 103 on the right. The second steel pipe column 204 is vertically arranged in two sections. The left side of each second steel pipe column 204 is fixedly connected to the right end of the second reinforcing bar beam 203. The interior of the second steel pipe column 204 is vertically continuous, and its inner diameter is larger than that of the second reinforcing bar column 202. This allows the second reinforcing bar column 202 of the subsequent stirrup module to be inserted into the second steel pipe column 204 of the preceding stirrup module. The height of the second steel pipe column 204 is lower than that of the second reinforcing bar column 202, ensuring that the two stirrup modules are at the same height after the second reinforcing bar column 202 is inserted, thus guaranteeing the flatness of the stirrup channel. When encountering an L-shaped floor structure, multiple stirrup modules can be interconnected and spliced through the second reinforcing bar column 202 and the second steel pipe column 204 to form an L-shaped stirrup channel.
[0029] It also includes a second reinforcing beam 205; the second reinforcing beam 205 is horizontally arranged front and rear, and its two ends are fixedly connected to the opposite side of the two second steel pipe columns 204 respectively. The second reinforcing beam 205 is used to connect the two second steel pipe columns 204, and at the same time, when the second steel bar columns 202 and the second steel pipe columns 204 of multiple stirrup modules are connected to each other, the second reinforcing beam 205 can play a transition role.
[0030] The angle between the front end of the first reinforcing bar folded beam 103 and the right end of the second reinforcing bar folded beam 203 and the ground is 45°. Since the height of the steel pipe column is lower than that of the reinforcing bar column, the steel pipe column and the reinforcing bar column can be smoothly connected through the inclined bend of the reinforcing bar folded beam.
[0031] In a further embodiment, the second connecting beam 201, the second reinforcing bar column 202, the second reinforcing bar folded beam 203, the second steel pipe column 204, and the second reinforcing beam 205 are all HRB400 grade threaded steel bars; the first steel pipe column 102 is a Q235 grade round steel pipe.
[0032] In a further embodiment, the second connecting beam 201, the second reinforcing bar column 202, the second reinforcing bar folded beam 203, the second steel pipe column 204, and the second reinforcing beam 205 all have a diameter of 16mm; the second steel pipe column 204 has an outer diameter of 20mm, an inner diameter of 19mm, and a wall thickness of 1mm.
[0033] The working principle of this utility model is as follows:
[0034] S1 stirrup module mass prefabrication: Stirrup modules are customized according to the actual floor size, including the height of the stirrup module, the length in the front-to-back direction and the width in the left-to-right direction.
[0035] S2 transport stirrup modules: Transport and hoist multiple stirrup modules to the construction site floors;
[0036] S3 stirrup assembly: such as Figure 3 As shown, multiple stirrup modules are spliced together according to the floor slab structure to form a stirrup channel; when the floor slab structure is rectangular, the two first steel reinforcement columns 101 of the latter stirrup module are inserted into the first steel pipe column 102 of the former stirrup module, and multiple stirrup modules are connected to each other in this way to form a long stirrup channel.
[0037] like Figure 4 As shown, when the floor slab structure has an arc shape, one of the first steel reinforcement columns 101 of the subsequent stirrup module is inserted into the first steel pipe column 102 on the same side of the preceding stirrup module. The subsequent stirrup module is rotated so that it forms an angle with the preceding 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 will form an angle with the preceding stirrup module after rotation, there will be a gap between the subsequent stirrup module and the preceding stirrup module. In order to prevent the gap from being too large and causing construction workers to step into the gap, the number of stirrup modules can be increased during splicing to reduce the angle angle, thereby reducing the gap between the two stirrups and ensuring safety.
[0038] like Figure 5-6 As shown, when the floor slab structure has an L-shaped structure, the two second steel reinforcement columns 202 of the latter stirrup module are inserted into the second steel pipe column 204 of the former 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 reinforcement columns 202 of the latter stirrup module can be inserted into the second steel pipe column 204 on the same side of the former stirrup module, and the latter stirrup module is rotated so that it forms an angle with the former stirrup module to form an arc-shaped stirrup channel;
[0039] S4 Stirrup Module Recycling: Multiple stirrup modules are dismantled and recycled before the concrete initially sets;
[0040] S5 maintenance: Clean the concrete and debris off each stirrup module;
[0041] S6 Turnover: The maintained stirrups are moved to the next construction floor, and S3-S5 are repeated until the construction of all floors is completed.
[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
