Description

A high-strength alloy steel formwork reinforcement structure for structural columns at T-shaped walls

Technical Field

The invention relates to the technical field of building construction, and in particular to a high-strength alloy steel template reinforcement structure for structural columns at a T-shaped wall.

Background Art

A structural column refers to a reinforced concrete column made in the masonry part specified in the code, according to the structural reinforcement and the construction sequence of first building the wall and then pouring the structural column. Its function is to improve the shear resistance of the masonry wall, improve the earthquake resistance and enhance the bearing capacity.

When building a T-shaped wall, workers will reserve space for pouring structural columns in the built wall, and then close the space with formwork. The formwork needs to be reinforced after installation, and the existing formwork reinforcement method generally uses tension screws that pass through the structural columns and filler walls to tighten and reinforce them.

However, this type of formwork reinforcement method has the following problems: after the concrete solidifies, the tie rods become difficult to pull out due to the strong wrapping force of the concrete, which limits their reuse, resulting in increased costs and waste of resources. In addition, since the formwork is tightly fixed by multiple tie rods, it becomes difficult to move a large area of the formwork when removing it, and it is very easy to damage the formwork. For tie rods that cannot be pulled out directly, the part on the concrete surface must be removed by cutting, which not only consumes additional materials and labor, but also may leave oil stains on the concrete surface, further increasing the complexity and cost of subsequent cleaning work.

Summary of the invention

The purpose of the present invention is to propose a high-strength alloy steel formwork reinforcement structure for structural columns at T-shaped walls in order to solve the problem that the formwork is difficult to remove and the tension screws are difficult to pull out, and the exposed parts of the tension screws need to be cut.

The limit slide slot 31 and the limit slider 54 are in a "T" shape when viewed from above. In this shape, the limit slider 54 can only slide up and down, and the limit slider 54 cannot be pulled out from the front.

As shown in FIGS. 3 and 6 , the pitch-changing unit 52 includes a folding rod group 521 rotatably connected to the crossbar 51 , support blocks are fixed to the two connecting plates 53 , a guide rod 522 is fixed to the two support blocks , and a sliding member 523 is slidably sleeved on the guide rod 522 ;

Two threaded holes are provided on the front side of the guide rod 522, and a positioning bolt 524 matching the threaded hole is passed through the bottom thread of the front side of the sliding member 523. When the folding rod group 521 is in a folded state, the sliding member 523 is below the guide rod 522. At this time, the positioning bolt 524 is screwed into the threaded hole below the front side of the guide rod 522, so that the position of the folding rod group 521 can be fixed, and then the position of the cross bar 51 can be fixed. The same applies after it is unfolded upward.

A fixing bolt is threaded through the bottom cross bar 51, and the bottom cross bar 51 is fixed to the square wood 30 by the fixing bolt. Two shear support seats 55 slidably connected to the limiting slide groove 31 are fixed to the bottom of the bottom cross bar 51. After the installation is completed, the shear support seats 55 are in a state of being against the ground, providing auxiliary support for the cross bar 51.

As shown in Figures 1 and 7, the positioning unit 40 includes a vertical tube 41, the top and bottom of the inner wall of the vertical tube 41 are engraved with internal threads, the top and bottom of the inner cavity of the vertical tube 41 are threadedly connected with an adjusting stud 42, one end of the adjusting stud 42 is rotatably connected to a top block 43 through a bearing, a movable sleeve 44 is fixed on the outer wall of the linkage plate 63, the movable sleeve 44 is slidably sleeved on the vertical tube 41, one of the movable sleeves 44 is threaded with a fastening bolt, one of the movable sleeves 44 is fixed to the vertical tube 41 by the fastening bolt, and by rotating the adjusting stud 42 in different directions, the adjusting stud 42 can be extended outward or contracted inward, thereby realizing the displacement of the top block 43.

In the initial state, the support block 61 and the cross bar 51 are both in a contracted state, and in this state, the linkage plate 63 matches the height of the cross bar 51 . In the initial state, when the vertical tube 41 moves inward, the linkage plate 63 can be directly sleeved on the cross bar 51 .

The four support blocks 61 are all provided with limit rods 64, the four limit rods 64 are staggered with each other, and a through groove is opened on the side of the upper surface of the four support blocks 61 away from the limit rod 64, the through groove is used to enable the limit rod 64 located above to pass through the support block 61 below after the support block 61 is folded, the top ends of the four limit rods 64 are respectively fixed to the lower surface of the support block 61 located above it, and a limit guide rod 65 is fixed on the support block 61 located at the bottom, and the other four support blocks 61 are slidably mounted on the limit guide rod 65.

Specifically, when the high-strength alloy steel formwork reinforcement structure of the structural column at the T-shaped wall is working/in use:

First, after the template 20 is supported, the variable cross bar assembly 50 is placed on the front of the template 20, and then the positioning unit 40 and the abutting unit 60 are installed on both sides of the template 20. During installation, the linkage plate 63 needs to be inserted on both sides of the cross bar 51. At this time, the sliding member 523 is moved upward to make the folding rod group 521 unfold upward, so that the cross bar 51 and the linkage plate 63 are equidistantly unfolded. After unfolding, the positioning bolt 524 is tightened to fix the position of the sliding member 523, and then the positioning unit 40 is gradually moved inward to make the pad 62 abut against the template 20, and then the adjusting stud 42 above the vertical pipe 41 is rotated counterclockwise to make the upper abutting block 43 abut against the ceiling. Top, at this time, the positions of the support block 61 and the pad 62 are fixed, and then the fixing bolts 66 are rotated to move the cross bar 51 toward the template 20, so that it abuts the square wood 30, and after abutting, it cooperates with the support block 61 to form a pulling and clamping state for the template 20. At this time, the reinforcement of the template 20 is completed. When disassembling, first turn the upper adjusting stud 42 clockwise to separate the abutting block 43 from the ceiling. At this time, the restriction on the support block 61 is released, and then the fixing bolts 66 are loosened. At this time, the vertical pipe 41 is moved to one side, and the abutting unit 60 can be moved outward as a whole, and then the variable cross bar assembly 50 and the square wood 30 are directly removed, and then the template 20 can be quickly disassembled.
