Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a grouting device for reinforcing bar columns of a warehouse frame. Background Technology

[0002] The frame columns of a warehouse are important supporting components of the warehouse structure. They bear the weight of the warehouse roof, roof panels, shelves, and goods, transferring these loads to the foundation to ensure the stability of the warehouse structure. They also resist horizontal forces such as wind loads and seismic loads, enhance the overall lateral force resistance of the warehouse, and enable the warehouse to maintain its structural integrity under various natural forces.

[0003] Currently, frame columns are generally constructed using the method of pre-embedded holes. First, corrugated pipes are used to position and fix the main reinforcement of the frame column. Then, the foundation bottom reinforcement is tied. After the foundation concrete is poured, plastic plugs are used to seal the pipe ends. After the steel cage and steel formwork are hoisted as a whole (the main reinforcement of the column is inserted into the pre-embedded corrugated pipe), C60 high-strength grouting material is used for grouting.

[0004] However, this pouring method involves directly introducing the grout into the top of the foundation and then into the sleeve. This method of grouting can easily lead to insufficient concrete density, affecting the strength of the frame columns and foundation joints, and thus affecting structural safety. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a grouting device for reinforcing bar columns in warehouse frame structures.

[0006] The technical solution of this utility model is: a grouting device for reinforcing bars in a warehouse frame column, comprising a frame column steel mold, a foundation cap, a sleeve, and embedded reinforcing bars; a column reinforcing cage is provided inside the frame column steel mold, and the main reinforcing bars at the lower end of the column reinforcing cage extend out of the lower end of the frame column steel mold, with the extended length being close to half the height of the foundation cap; the embedded reinforcing bars are evenly arranged inside the foundation cap and close to the bottom of the foundation cap; the lower part of the sleeve is coaxially fitted onto the upper part of the embedded reinforcing bars, and the main reinforcing bars are coaxially inserted into the upper part of the sleeve, with the main reinforcing bars and the embedded reinforcing bars extending into the sleeve by the same length, and the dimensions of the main reinforcing bars and the embedded reinforcing bars being the same; both the embedded reinforcing bars and the inserts are threaded steel bars, and the inner diameter of the sleeve is larger than the diameter of the inserts, so that a grouting cavity can be formed inside the sleeve; a grouting pipe is provided radially at the lower part of the sleeve, with the outer end of the grouting pipe extending out of the side of the foundation cap.

[0007] Preferably, the outer ends of the grouting pipes are connected by a common annular pipe. The annular pipe is a square ring, and the four pipes of the square ring are connected by elbows. The main pipe is connected to the annular pipe.

[0008] Preferably, the upper part of the sleeve is provided with an overflow pipe in the radial direction, the outer end of the overflow pipe extends out of the outer side of the foundation platform, and the overflow pipe is close to the upper port of the sleeve.

[0009] Preferably, the annular pipe and the grouting pipe are connected by a T-joint, and the main pipe and the annular pipe are connected by a T-joint. Both the annular pipe and the main pipe are plastic pipes.

[0010] Preferably, a gap is provided between the end faces of the main column reinforcement and the embedded reinforcement, and a grouting cavity is formed between the main column reinforcement, the embedded reinforcement and the sleeve, and the gap is connected to the grouting cavity inside the sleeve.

[0011] Preferably, the upper end of the sleeve extends beyond the upper surface of the foundation pier, extending only a certain length.

[0012] Preferably, the foundation platform is square, and the sleeves and embedded steel bars inside it are arranged in a square ring.

[0013] The beneficial technical effects of this utility model are:

[0014] (1) This utility model uses grouting into the casing for pouring construction. Grouting into the casing has a higher pressure and the concrete density is higher than that of grouting into the casing, which ensures the strength of the frame column and foundation node.

[0015] (2) This utility model connects the grouting pipes around the foundation cap through a ring pipe, and grouts all the sleeves from one pipe opening. The quality of the internal pouring of each sleeve is judged by whether the grout flows out of the overflow pipe arranged horizontally on the upper part of the sleeve. The grouting operation is more convenient, saves construction time, and helps to improve the pouring quality. Attached Figure Description

[0022] Example 1, see appendix Figure 1-5 A grouting device for reinforcing bars in a warehouse frame column includes a frame column steel mold 1, a foundation pier 2, a sleeve 3, and pre-embedded reinforcing bars 4. The frame column steel mold 1 contains a reinforcing bar cage, with the main reinforcing bars 11 extending from the lower end of the cage. The pre-embedded reinforcing bars 4 are evenly arranged within the foundation pier 2. The lower part of the sleeve 3 is coaxially fitted over the upper part of the pre-embedded reinforcing bars 4, and the main reinforcing bars 11 are coaxially inserted into the upper part of the sleeve 3. The dimensions of the main reinforcing bars 11 are the same as those of the pre-embedded reinforcing bars 4, and the inner diameter of the sleeve 3 is larger than the diameter of the inserted body. A grouting pipe 31 is radially arranged at the lower part of the sleeve 3, with the outer end of the grouting pipe 31 extending beyond the side of the foundation pier 2.

[0023] A gap 51 is provided between the end faces of the main column reinforcement 11 and the pre-embedded steel bar 4. The gap 51 is connected to the grouting cavity 52 inside the sleeve 3. A transverse partition structure is formed in the grouting cavity 52 through the gap 51. After the concrete is poured, the middle tube can form a transverse reinforcement, which has a better reinforcement effect on the joint.

[0024] The upper end of the sleeve 3 extends out of the upper surface of the foundation 2. The sleeve provides guidance for insertion and plays a role in protecting the foundation. The foundation 2 is square, and the sleeve 3 and the pre-embedded steel bars 4 inside it are arranged in a square ring.

[0025] The construction method of the grouting device in this embodiment is as follows:

[0026] ① Before pouring concrete for the foundation, the sleeve 3 is pre-embedded and fixed according to the column main reinforcement 11 and the sleeve 3 positioning diagram. The column main reinforcement 11 reserved in the foundation 2 is inserted into the sleeve 3 to about half of its length. Before pre-embedding the sleeve 3, the lower opening is sealed with transparent tape, and the upper opening and the grouting port and grout outlet on the side are sealed with caps to prevent concrete from entering the grouting sleeve 3 during pouring.

[0027] ②Pour concrete for the foundation;

[0028] ③ Binding of column reinforcement cages, and assembly of column reinforcement cages with frame column steel formwork 1;

[0029] ④ Lay out the top of the foundation cap 2 with a chalk line, mark the column center line and column section edge line, and level with mortar;

[0030] ⑤ The steel formwork 1 of the frame column is vertically lifted off the ground at a certain height and lifted to the position of the foundation platform 2. 3-4 people insert the steel cage of the column formwork into the grouting sleeve 3, so that the steel bars are as centered as possible in the sleeve 3, and ensure that the position of the steel formwork 1 of the frame column is at the positioning line of the column.

[0031] ⑥ Use a theodolite to adjust the verticality of the frame column steel formwork 1. After the adjustment is completed, fix the frame column steel formwork 1 by pulling guy ropes around it and avoid collision with tool-type guardrails during lifting.

[0032] ⑦ During grouting, the well-mixed concrete is connected to the grouting sleeve through the grouting bucket, grouting pump and grouting main pipe, etc. The grouting process is controlled by the grouting pump pressurization and pressure gauge control, and the grout flow rate is controlled. The grout mixture is pressurized by the grouting pump and flows from the grouting bucket along the grouting pipe 31 into the grouting port at the bottom of each sleeve 3, and flows upward with the pressure to fill the grouting cavity 52 of the entire sleeve 3.

[0033] ⑧ After grouting is completed, reduce the pressure of the grouting pump and maintain the pressure for 1 minute. After the pressure is maintained, remove the grouting pipe 31 and seal the grouting port with a rubber plug. After the concrete has solidified and reached a certain strength, remove the rubber plug, clean the surrounding ground, and complete the burial of the soil layer around the foundation. This method is simple to operate, can significantly improve the grouting speed, ensure the grouting density, and improve the connection strength between the foundation and the frame column.

[0034] Example 2, see appendix Figure 1 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the outer ends of the grouting pipes 31 are connected to a common annular pipe 32, the main pipe body 33 is connected to the annular pipe 32, the annular pipe 32 and the grouting pipes 31 are connected by a T-joint 35, and the main pipe body and the annular pipe are connected by a T-joint.

[0035] In this embodiment, the grouting pipes 31 around the foundation cap 2 are connected by a ring pipe 32, and all the sleeves 3 are grouted from one pipe opening. The quality of the internal pouring of each sleeve 3 is judged by whether the grout flows out of the overflow pipe 34 arranged horizontally on the upper part of the sleeve 3. The grouting operation is more convenient, saves construction time, and helps to improve the pouring quality.

[0036] Example 3, see appendix Figure 2 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the upper part of the sleeve 3 is provided with an overflow pipe 34 radially. The outer end of the overflow pipe 34 extends out of the outer side of the foundation pier 2. The overflow pipe 34 is used to observe whether the grouting concrete flows out. When the grouting concrete flows out of the overflow pipe 34 and there are no air bubbles, it is sealed with a rubber stopper in time. All overflow pipes 34 can be sealed after the concrete flows out normally. The grouting situation can be easily observed through these radially arranged overflow pipes to ensure the construction quality.
