The gate valve plate is inserted in the radial channel so that the valve hole is communicated with or staggered with the inner hole of the pipe hoop.
And two ends of the pipe hoop are provided with hoop grooves so as to be reliably connected with the steel column grouting pipe end or the grouting pump truck grouting pipe end through a pipe clamp.
The pipe hoop comprises a left pipe hoop and a right pipe hoop, two base plates are connected between the left pipe hoop and the right pipe hoop, and the end faces of the left pipe hoop and the right pipe hoop and the two base plates enclose the radial channel. Flanges are arranged on the end faces of the left pipe hoop and the right pipe hoop connected with the base plate. The flange is a square flange.
The upper end and the lower end of the gate valve plate are provided with baffle plates, so that the gate valve plate is prevented from falling off during movement.
The gate valve plate can be pulled radially (in a direction perpendicular to the axis of the pipe clamp inner hole) relative to the pipe clamp inner hole. The valve opening aligns with the inside grout hole of left ferrule and right ferrule when the gate valve board removes one end, and the gate valve is in the open mode, and grout passageway is opened, realizes the grout. When the gate valve plate moves to the other end, the valve hole is completely staggered with the inner grouting holes of the left pipe hoop and the right pipe hoop, the gate valve is in a closed state, and the grouting channel is closed.
The utility model discloses the structure is reliable, construction convenience, is applied to the inside grout operation of steel tubular column and accomplishes the front and back in the steel construction building, has realized opening and closing of grout passageway between grout pump truck and steel pipe column, can use the land pump pipe strap with left ferrule and right ferrule and pump truck or other grout pipe direct reliable connection.

In the figure: 1. the pipe comprises a left pipe hoop, a right pipe hoop, a gate valve plate, a backing plate, a fastening bolt, a hoop groove, a baffle plate, a valve hole, a flange, a grouting facility and a gate valve, wherein the gate valve plate is arranged at the position 3, the backing plate is arranged at the position 4, the fastening bolt is arranged at the position 5, the hoop groove is arranged at the position 6, the baffle plate is arranged at the position 7.
Detailed Description
The invention will be described in detail with reference to the drawings, which are provided for illustrative and explanatory purposes only and should not be construed as limiting the scope of the invention.
As shown in fig. 1 and 2, the gate valve for internal grouting of a steel pipe column of the present invention mainly comprises a left pipe clamp 1, a right pipe clamp 2, a gate valve plate 3 and a backing plate 4. One end of the left pipe hoop 1 and the right pipe hoop 2 is provided with a square flange 9, and the other end is provided with a hoop groove 6. The left pipe hoop 1 and the right pipe hoop 2 are provided with square flanges 9, one ends of the square flanges 9 are arranged oppositely, two base plates 4 are arranged between the left pipe hoop 1 and the right pipe hoop 2, the left pipe hoop 1, the right pipe hoop 2 and the base plates 4 are connected together through fastening bolts 5, an upper channel and a lower channel which are communicated with each other are formed between the two base plates 4, a gate valve plate 3 is inserted into the channel, and the upper end and the lower end of the gate valve plate 3 extend out of a radial channel. The gate plate 3 can move up and down in the channel. The gate valve plate 3 is provided with a valve hole 8. The upper and lower ends of the gate valve plate 3 are provided with the baffle plates 7 to prevent the gate valve plate 3 from being pulled out during movement
As shown in fig. 3, the gate valve plate 3 can be pulled radially with respect to the left and right pipe clamps 1 and 2. When the gate valve plate 3 moves to one end, the valve hole 8 can be aligned with the internal grouting holes of the left pipe clamp 1 and the right pipe clamp 2 (on the same axis), the gate valve is in an open state (see fig. 3(a)), the grouting channel is opened, and grouting is realized. When the gate valve plate 3 moves to the other end, complete dislocation of the valve hole 8 and the inside grouting holes of the left pipe clamp 1 and the right pipe clamp 2 can be realized, the channel between the left pipe clamp 1 and the right pipe clamp 2 is blocked, the gate valve is in a closed state (see fig. 3(b)), the grouting holes of the left pipe clamp and the right pipe clamp are blocked through the gate valve plate 3, and the grouting channel is closed.
The gate valve is applied to the steel pipe column in the steel structure building before and after the grouting operation is completed, and the opening and closing of the grouting channel between the grouting pump truck and the steel pipe column are realized. The gate valve can be an independent part, can also be integrated with other grouting accessories into a whole, and can be detached after grouting materials are basically solidified during the independent structure for recycling. The whole gate valve can be of a steel structure and can also be made of materials with other strength meeting the strength requirement.
