Description

Technical Field

[0001] The invention relates to the field of nuclear power building construction, and in particular to a reinforcement method for improving the installation accuracy of wall embedded parts. Background Art

[0002] At present, the wall embedded parts of some construction projects are characterized by large number, heavy weight, complex structure, and dense wall structural steel bars. According to the traditional wall embedded parts reinforcement method, one end of the top support steel bar is generally supported on the back of the embedded part, and the other end is supported on the formwork. Because direct spot welding of the structural force-bearing steel bars is strictly prohibited, the top support steel bar is tied and fixed with the structural steel bar through the measure reinforcement steel bar and the structural steel bar with steel bar ties. However, this reinforcement method is easy to cause the measure reinforcement steel bar to loosen due to concrete flow and vibration construction during the concrete pouring process, thereby causing the top support steel bar of the embedded part to loosen and lose its top support function. The embedded parts will eventually have problems such as deviation and depression, making it difficult to control the installation accuracy of the embedded parts. After the formwork is removed, the installation error of some embedded parts exceeds the allowable requirements, and the embedded parts need to be processed before they can be put into use, which often causes construction quality risks and delays in construction progress.

[0003] With the increasing quality management requirements and severe supervision in the construction industry, as well as the disappearance of industry dividends and labor shortage, the reinforcement method of embedded wall parts must be optimized to improve the quality of wall construction and increase economic efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a reinforcement method for improving the installation accuracy of wall embedded parts in view of the problem that traditional wall embedded parts reinforcement methods are difficult to control the installation accuracy of embedded parts. This method can avoid the occurrence of deviation, depression, etc. of embedded parts after pouring, which is beneficial to improving the installation accuracy of wall embedded parts.

[0005] The present invention is achieved through the following technical solutions:

[0006] The present invention provides a reinforcement method for improving the installation accuracy of wall embedded parts. After the wall structure steel bars are tied, a clamp is fixed on the structural steel bars, the measure reinforcement steel bars are welded to the clamp, and at the same time, the measure reinforcement steel bars and the embedded part anchor bars are tied with steel bar wires, and then the top support steel bars and the measure reinforcement steel bars are welded and fixed, so that one end of the top support steel bars supports the embedded part and the other end supports the opposite template, and then the top support steel bars are spot welded and fixed to the side of the embedded plate of the embedded part, so that the embedded part and the top support steel bars, the measure reinforcement steel bars and the structural steel bars form an integral system.

[0007] In the above scheme, a clamp is set on the structural steel bar behind the embedded part, and the clamp is welded to the measure reinforcement steel bar, and the measure reinforcement steel bar is tied to the embedded part anchor bar, and then the embedded part top support steel bar is welded and fixed to the measure reinforcement steel bar, and the top support steel bar is spot welded to the embedded plate side of the embedded part. Compared with the traditional reinforcement method, the embedded part and the structural steel bar are fixed as a whole, which effectively reduces the displacement of the embedded part caused by disturbance during the concrete pouring process, improves the installation accuracy of the embedded part, ensures the construction quality requirements, and improves the one-time acceptance rate.

[0008] In some embodiments, the clamp includes two semicircular tube-shaped clips, which are welded together to form a whole and then tightly sleeved on the structural steel bar. Since the clamp is divided into two semicircular tube-shaped clips, it is convenient to fix the clamp on the structural steel bar, and the welding is between the joints of the two clips, and does not directly act on the structural steel bar.

[0009] In some embodiments, the two clips are provided with welding grooves at the joint welds, so as to facilitate welding at the vertical fillet welds on both sides of the clips to form the overall structure of the fixture.

[0010] In some embodiments, the clamp includes two semicircular tube-shaped clips, each of which is provided with wing plates on both sides, and the two clips are detachably connected by the wing plates to form a whole and then tightly clamped on the structural steel bar. By detachably connecting the two semicircular tube-shaped clips by the wing plates, it is more convenient to install and remove the clamp on the structural steel bar.

[0011] In some embodiments, each of the wing plates has at least two connection holes, and the two clips are bolted into the connection holes to form a whole.

[0012] In some embodiments, the inner wall of the clip is provided with a thread, and after the two clips are connected as a whole, the thread engages with the steel bar rib of the structural steel bar. Such a design can enhance the connection force between the clamp and the structural steel bar.

[0013] In some embodiments, the length of the clip along the axial direction is 50-70 mm.

[0014] In some embodiments, the wall thickness of the clip is 4-6 mm.

[0015] In some embodiments, 4 to 8 of the clamps are fixed on the rear side of each embedded part.

[0016] In some embodiments, the top support steel bar is connected to a concrete pad at one end facing the formwork. This design prevents the end of the top support steel bar from directly contacting the formwork, ensuring that the top support steel bar is not exposed after the wall is poured.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] By setting a clamp on the structural steel bar behind the embedded part, and welding the clamp to the measure reinforcement steel bar, and at the same time tying the measure reinforcement steel bar to the embedded part anchor bar, and then welding the embedded part top support steel bar to the measure reinforcement steel bar, and at the same time spot welding the top support steel bar to the embedded plate side of the embedded part, compared with the traditional reinforcement method, the embedded part and the structural steel bar are fixed as a whole, which effectively reduces the displacement of the embedded part caused by disturbance during concrete pouring, improves the installation accuracy of the embedded part, ensures the construction quality requirements, and improves the one-time acceptance rate; the reinforcement method is simple to operate, convenient and practical, and has a wide range of applications. It is suitable for projects with high installation accuracy requirements for all kinds of wall embedded parts. It does not affect the structural steel bars, does not directly spot weld with the structural steel bars, has reliable reinforcement, and the embedded parts are not prone to dents or displacement.

[0038] Example

[0039] Please refer to Figure 1-Figure 7 A reinforcement method for improving the installation accuracy of wall embedded parts provided in an embodiment of the present application includes the following contents:

[0040] After the wall structure steel bars 5 are tied, the clamp 4 is fixed on the structural steel bars 5, and the measure reinforcement steel bars 6 are welded and fixed to the clamp 4 to improve the overall stability of the embedded parts;

[0041] At the same time, the reinforcement steel bar 6 and the embedded anchor bar 2 are tied together with steel bar tying wire to further fix the position of the embedded part;

[0042] Then weld and fix the top support steel bar 7 and the measure reinforcement steel bar 6 behind the embedded part, so that one end of it supports the embedded part and the other end supports the opposite template;

[0043] The top supporting steel bar 7 is then spot welded to the side of the embedded plate 1 of the embedded part, so that the embedded part, the top supporting steel bar 7, the measure reinforcing steel bar 6, the clamp 4, and the structural steel bar 5 form a reinforced overall system.

[0044] By setting a clamp on the structural steel bar behind the embedded part, welding the clamp to the measure reinforcement steel bar, and tying the measure reinforcement steel bar to the embedded part anchor bar, and then welding the embedded part top support steel bar to the measure reinforcement steel bar, and spot welding the top support steel bar to the embedded plate side of the embedded part, compared with the traditional reinforcement method, the embedded part and the structural steel bar are fixed as a whole, which effectively reduces the displacement of the embedded part caused by disturbance during the concrete pouring process, improves the installation accuracy of the embedded part, ensures the construction quality requirements, and improves the acceptance rate in one time.

[0045] It should be noted that the embedded parts in this embodiment include an embedded part embedded plate 1 and embedded part anchor bars 2, wherein there are multiple embedded part anchor bars 2 distributed on one side of the embedded part embedded plate 1 by welding.

[0046] According to some embodiments of the present application, the clamp 4 includes two semicircular tube-shaped clips 3, and the two clips 3 are welded together to form a whole and then tightly sleeved on the structural steel bar 5.

[0047] Since the clamp is divided into two semicircular tube-shaped clips, it is convenient to fix the clamp on the structural steel bar, and the welding is between the joints of the two clips and does not directly act on the structural steel bar.

[0048] In order to enable the clamp to be better fastened to the structural steel bar 5, the inner diameter of the semicircular tube-shaped clip 3 can be designed to be slightly smaller than the diameter specification of the structural steel bar 5, so that the clip 3 can be pressed onto the structural steel bar 5 by tools such as pliers, and then can be tightly fitted onto the structural steel bar after the two sides of the two clips are welded.

[0049] According to some embodiments of the present application, the two clips 3 are provided with welding grooves at the joint welds, so as to facilitate welding at the vertical fillet welds on both sides of the clips to form the overall structure of the clamp.

[0050] In order to facilitate the welding of the two clips 3, the welding groove angle opened on each side of the clip 3 can be 30-45 degrees, so that a fillet weld is formed along the axial direction on the same side of the two clips.

[0051] According to some embodiments of the present application, the clamp 4 includes two semicircular tube-shaped clips 3, each of which is provided with wing plates on both sides, and the two clips 3 are detachably connected by the wing plates to form a whole and then tightly clamped on the structural steel bar 5. By detachably connecting the two semicircular tube-shaped clips by the wing plates, it is more convenient to install and remove the clamp on the structural steel bar.

[0052] In order to enable the clamp 4 to be better tightened on the structural steel bar 5, the semi-circular tube-shaped clip 3 can be designed to adapt to the diameter specification of the structural steel bar 5, and the wing plate is offset by a certain distance from the center of the arc of the clip, similar to the construction principle of a clamp, so that the clamp 4 can be tightly clamped on the structural steel bar 5 after the fastener tightens the wing plate.

[0053] According to some embodiments of the present application, each of the wing plates is provided with at least two connection holes, and the two clips are formed as a whole by passing bolts through the connection holes.

[0054] In the above scheme, the two connection holes are evenly distributed on the wing plate along the axial direction of the clip, which is conducive to making the clamping force generated by the clamp on the structural steel bar more uniform after the two wing plates on the same side of the clip are tightened by bolts.

[0055] According to some embodiments of the present application, the inner wall of the clip 3 is provided with threads, and after the two clips 3 are connected as a whole, the threads engage with the steel bar ribs of the structural steel bar 5. Such a design can enhance the connection force between the clamp 4 and the structural steel bar 5.

[0056] According to some embodiments of the present application, the length of the clip 3 along the axial direction is 50-70 mm.

[0057] According to some embodiments of the present application, the wall thickness of the clip 3 is 4-6 mm.

[0058] According to some embodiments of the present application, 4 to 8 of the clamps 4 are fixed to the rear side of each embedded part.

[0059] According to some embodiments of the present application, the top support steel bar 7 is connected to a concrete pad 8 at one end facing the formwork. This design prevents the end of the top support steel bar from directly contacting the formwork, ensuring that the top support steel bar is not exposed after the wall is poured.

[0060] In this embodiment, 8 clamps are set as an example. According to the layout position of the embedded parts, the 8 clamps 4 are fixed on four vertical structural steel bars 5, and the 8 clamps 4 are distributed in the corners of a rectangular parallelepiped. There are four measures reinforcing steel bars 6, which are arranged horizontally and parallel to the embedded plate 1 of the embedded parts. Each measure reinforcing steel bar 6 is welded and fixed to two clamps 4 as a whole, and the measure reinforcing steel bars 6 and the intersecting embedded anchor bars 2 are tied with steel wire. There are four top support steel bars 7, which are arranged horizontally and perpendicular to the embedded plate 1 of the embedded parts. Each top support steel bar 7 is welded and fixed to two intersecting measure reinforcing steel bars 6, and then each top support steel bar 7 is spot welded and fixed to the side of the embedded plate 1 of the embedded parts, so that the embedded parts, top support steel bars 7, measure reinforcing steel bars 6, clamps 4, and structural steel bars 5 form an integral structure.

[0061] The embedded parts reinforcement method in the embodiment of the present application has the following advantages:

[0062] 1. Simple operation, convenient and practical;

[0063] 2. Widely applicable, suitable for projects with high installation precision requirements for all kinds of wall embedded parts;

[0064] 3. It does not affect the structural steel bars and does not directly spot weld with the structural steel bars;

[0065] 4. The reinforcement is firm and the embedded parts are not prone to dents or displacement.

[0066] Tests have shown that the embedded parts of the wall reinforced in this way rarely have quality problems such as displacement and depression after concrete pouring and demolding, which greatly improves the construction quality and saves the processing time caused by quality problems of the embedded parts.

[0067] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
