TECHNICAL FIELD

[0001] The present application relates to the field of building engineering technology, in particular to a concrete building steel plate reinforcing structure and construction method. BACKGROUND

[0002] Steel bonding reinforcement, also known as steel plate bonding reinforcement, is to bond steel plates to the surface of concrete members using high-performance epoxy adhesives, so that the steel plates and the concrete form a unified whole, and the good tensile strength of the steel plates is used to enhance the load-bearing performance of the members. Especially in the load-bearing structure of the building concrete beam column, the safety and stability of the building are improved.

[0003] The steel bonding reinforcement in the related art is usually performed after the building beam column is formed, the surface of the beam column is usually smoothed after the beam column is formed, the steel bars of the beam column are detected in sections, the punching position is set, and then the bolts are inserted into the holes through the steel plate and fixed by glue injection.

[0004] For the related art in the above, the inventors found that in the construction process of the existing concrete building, wooden formworks are usually erected to bear and shape the building structure, and in the process of pouring concrete into the wooden formworks and solidifying the concrete, the formworks and the building surface often deform under pressure. The surface treatment process of the building beam during steel bonding reinforcement consumes too much human resources. SUMMARY

[0005] In order to reduce the deformation of the building beam surface as much as possible during the reinforcement of the building beam using steel plates, and reduce the human resources consumed by the steel bonding reinforcement process, the present application provides a concrete building steel plate reinforcing structure and construction method.

[0006] Firstly, the concrete building steel plate reinforcing structure provided by the present application adopts the following technical scheme:

[0008] The prefabricated frame comprises two edge angle steels arranged along the length direction of the building beam, a plurality of bottom plates fixed at intervals between the two edge angle steels, and a plurality of side wing steel plates integrally arranged on the top of the edge angle steels;

[0009] When the building beam is solidified and formed, the plurality of bottom plates are embedded on the lower surface of the building beam, and the plurality of side wing steel plates are embedded on the side wall of the building beam.

[0010] By adopting the technical scheme, the prefabricated frame is integrally formed on the surface of the concrete building beam by being previously arranged in the formwork of the building beam. The prefabricated frame structure protects the building beam, avoids the processes of detection, punching and glue injection on the building beam after forming as much as possible, shortens the construction time as much as possible, and saves a large amount of human resources.

[0019] Optionally, the threaded hole does not penetrate the prefabricated frame.

[0020] By adopting the technical scheme, the situation that the concrete slurry seeps into the threaded hole and hinders the normal disassembly of the beam formwork is reduced.

[0021] Optionally, the side wing steel plates on the different edge angle steels on the prefabricated frame correspond to each other, a limiting piece is arranged between the two corresponding side wing steel plates, the limiting piece comprises a strip-shaped tensile part and a clamping part fixedly connected to both ends of the tensile part.

[0022] The side of the two side wing steel plates facing each other is provided with a T-shaped clamping groove matched with the limiting piece, and the two clamping parts of the limiting piece are slidingly connected in the clamping groove.

DETAILED DESCRIPTION

[0045] The following will be described in detail in combination with the accompanying drawings. Figures 1-3 The application will be further described in detail.

[0046] In a first aspect, the embodiment of the application discloses a concrete building steel plate reinforcing structure and a construction method. Referring to Figure 1 The steel plate reinforcing structure in the embodiment includes a building beam 1 and a prefabricated frame 2 which is prearranged in the formwork and formed with the concrete beam before pouring the building beam 1.

[0047] Referring to Figure 2The prefabricated frame 2 is arranged on the inner wall of the inner cavity of the beam formwork 3, the prefabricated frame 2 comprises two edge angle steels 21 arranged along the length direction of the building beam 1, a plurality of bottom plates 22 fixed at intervals between the two edge angle steels 21, and a plurality of side wing steel plates 23 integrally arranged vertically on the top surface of the edge angle steels 21, the plurality of side wing steel plates 23 are arranged at equal intervals on the top surface of the edge angle steels 21, and the side wing steel plates 23 and the bottom plates 22 on the two different edge angle steels 21 form a “U” type structure corresponding to each other to cover the building beam 1.

[0048] When the building beam 1 is solidified and formed, the bottom plates 22 are embedded in the lower surface of the building beam 1, the side wing steel plates 23 are embedded on the side wall of the building beam 1, and the edge angle steels 21 cover the lower corner of the building beam 1.

[0049] In the embodiment, the prefabricated frame 2 is arranged in the formwork of the building beam 1 in advance, so that the prefabricated frame 2 is integrally formed on the surface of the concrete building beam 1, covers and protects the surface of the building beam 1, strengthens the stress performance of the building beam 1, and avoids detecting, punching and injecting glue on the building beam 1 as much as possible, thereby shortening the construction time and saving a large amount of human resources.

[0050] Referring to Figure 2 Each bottom plate 22 is fixed with two limiting rods 221, the two limiting rods 221 are located on the two sides of the beam internal reinforcement cage 11, and the top end of the limiting rod 221 is hinged with a hook 222 for hooking the beam internal reinforcement cage 11.

[0051] After the prefabricated frame 2 is arranged in the inner cavity of the beam formwork 3, the beam internal reinforcement cage 11 is arranged in the inner cavity of the building beam 1. The position of the beam internal reinforcement cage 11 is usually fixed with the reinforcement cage in the building wall, but the reinforcement cage in the building wall is high in height and large in weight, and often leans on the inner wall of a side of the building wall formwork, so that the beam internal reinforcement cage is not uniformly distributed. The limiting rod 221 can limit the position of the beam internal reinforcement cage 11, so as to reduce the uneven stress performance of the building beam 1 caused by the deviation of the position of the beam internal reinforcement cage 11. Meanwhile, the hook 222 can connect the prefabricated frame 2 and the beam internal reinforcement cage 11, so as to improve the integrity between the prefabricated frame 2 and the beam internal reinforcement cage 11, and reduce the separation of the prefabricated frame 2 and the building beam 1 under a large force.

[0052] The prefabricated frame 2 is detachably connected with the building beam 1 template through the connecting piece. Specifically, the "U"-shaped structure uniformly distributed on the prefabricated frame 2 is connected with the beam template 3 through a plurality of bolts 4, and the surface of the prefabricated frame 2 facing the beam template 3 is provided with a plurality of threaded holes 24 which do not penetrate the prefabricated frame 2. The bolt 4 is threadedly connected in the threaded hole 24 through the beam template 3.

[0053] The connection of the prefabricated frame 2 and the beam template 3 can strengthen the beam template 3 to a certain extent, and reduce the local bulging and deformation of the building beam 1 template. The beam template 3 can position the position of the prefabricated frame 2. The prefabricated frame 2 and the beam template 3 are tightly attached to each other, thereby effectively reducing the situation that the concrete slurry seeps between the prefabricated frame 2 and the beam template 3.

[0054] The threaded hole 24 which does not penetrate the prefabricated frame 2 can avoid the hindrance caused by the seepage of the concrete slurry into the threaded hole 24 to the workers when removing the beam template 3; and the structure that the bolt 4 fixes the prefabricated frame 2 from the outside of the beam template 3 can make it more convenient for the workers to remove the beam template 3, thereby reducing the damage of the beam template 3 during the removal process.

[0055] Referring to Figure 2 and Figure 3 , further, a limiting piece 25 is arranged between the two mutually corresponding side wing steel plates 23, the limiting piece 25 includes a strip-shaped tensile part 251 and a clamping part 252 coaxially fixed at both ends of the tensile part 251, the clamping part 252 is disc-shaped, and the tensile part 251 is made of metal cable.

[0056] The side of the two mutually corresponding side wing steel plates 23 facing each other is provided with a "T"-shaped clamping groove 231 matched with the limiting piece 25, and the clamping groove 231 extends upward to the upper surface of the side wing steel plate 23. The two clamping parts 252 of the limiting piece 25 are slidingly connected in the clamping groove 231 to limit the distance between the two side wing steel plates 23, thereby further reducing the situation that the upper part of the building beam 1 expands to both sides under the pressure, and ensuring the stability of the building beam 1 structure.

[0057] At least two sliding rings 253 are sleeved on each limiting piece 25, and a hooking part 254 for connecting the top of the beam steel cage 11 is fixed on the sliding ring 253.

[0058] The threaded hole 24 at the top end of the prefabricated frame 2 is arranged at the position corresponding to the clamping groove 231 and communicates with the inner cavity of the clamping groove 231, and the connecting hole 2521 corresponding to the threaded hole 24 in the clamping groove 231 is arranged on the surface away from the tensile part 251 of the clamping part 252. The connecting hole 2521 is provided with an internal thread corresponding to the bolt 4, and the bolt 4 is sequentially threaded through the beam formwork 3 and the side wing steel plate 23 and then is threadedly connected in the connecting hole 2521, so that the position of the limiting part 25 is fixed, and the deviation of the limiting part 25 during pouring and solidification of the building beam 1 is further reduced.

[0059] With reference to Figure 2 and Figure 4 It should be noted that in order to adapt to various types of building beams 1 in buildings, the bottom plate 22 is provided with various types of corresponding models, and workers can select different lengths of the bottom plate 22 according to actual conditions. Meanwhile, the prefabricated frame 2 further comprises a lengthening plate 26 for lengthening the side wing steel plate 23, the lengthening plate 26 has the same width as the side wing steel plate 23, and the upper surface of the lengthening plate 26 is provided with the same groove structure 261 as the clamping groove 231, and the lower surface of the lengthening plate 26 is fixedly connected with the plug 262 which is completely matched with the clamping groove 231. The fixing hole 2621 which has the same structure as the connecting hole 2521 is arranged on the plug 262 at the position corresponding to the threaded hole 24 in the clamping groove 231.

[0060] After the plug 262 of the lengthening plate 26 is embedded in the clamping groove 231, the bolt 4 is sequentially threaded through the beam formwork 3 and the side wing steel plate 23 and is threadedly connected in the fixing hole 2621, so that the beam formwork 3, the side wing steel plate 23 and the lengthening plate 26 are fixed together. Thus, the prefabricated frame 2 can adapt to building beams 1 with different beam heights.

[0061] On the other hand, the application discloses a construction method of a concrete building steel plate reinforcing structure, which adopts the following steps:

[0062] Assembling the prefabricated frame 2 according to the specifications of the building beam 1;

[0063] Placing the assembled prefabricated frame 2 in the inner cavity of the overlapped beam formwork 3;

[0064] Arranging a through hole on the beam formwork 3 at the position corresponding to the threaded hole 24;

[0066] Overlapping the beam inner cage in the building beam 1 and hanging the hook 222 on the bottom of the beam inner reinforcement cage 11;

[0067] After the beam steel cage 11 is built, the limiting piece 25 is inserted into the clamping groove 231 of the corresponding side wing steel plate 23, and the hooking part 254 on the limiting piece 25 is hooked on the top of the beam steel cage 11;

[0068] The concrete slurry is poured into the beam formwork 3, and the building beam 1 is formed;

[0069] After the building beam 1 is formed, the beam formwork 3 is removed.

[0070] As an optional technical solution, the reinforcing strips are fixed on the outer wall of the beam formwork 3 and arranged along the length direction of the building beam 1, the through holes corresponding to the through holes are formed in the reinforcing strips, and the reinforcing strips are installed on the beam formwork 3 through the bolts 4, so that the beam formwork 3 is further reinforced, and the deformation amount of the building beam 1 is reduced.
