Description

A connection device for fixing a structural column formwork to a wall

technical field

The utility model relates to the technical field of building construction, in particular to a connection device for fixing a construction column formwork and a wall.

Background technique

Structural columns are important concrete components in brick-concrete structures. In order to improve the seismic performance of the masonry structure of multi-storey buildings, the code requires that reinforced concrete columns should be installed in appropriate parts of the masonry of the house and connected with ring beams to jointly enhance the stability of the building. Such reinforced concrete columns are often called structural columns. Structural columns are not mainly used to bear vertical loads, but to resist shear forces, earthquakes and other lateral loads. Structural columns are usually set at the rest platform in the stairwell, at the junction of vertical and horizontal walls, at the corner of the wall, and at the middle part of the wall up to five meters long. In recent years, in order to improve the bearing capacity or stability of the masonry structure without increasing the cross-sectional size, the structural columns in the wall are not only set at the corners and edges of the wall of the house, but also in the middle of the wall as required. The ring beam must be set in a closed shape. The existing structural columns are all poured through the structural column formwork. When pouring concrete, it is usually necessary to assemble the structural column box with the building board first, and then pour the concrete into the box. After the concrete is completely dry, the building board is removed. Next, the formation of the structural column is completed at this time. Now, for the reinforcement of the end construction column building board, most of them are clamped and reinforced by traditional step-by-step tightening, but when step-by-step tightening is used, one end needs to be fixed, and then the movable end is tapped to clamp and fix the formwork, but in Before using step by step to clamp, it is necessary to make holes in the infill wall that has been built. This is very easy to cause damage to the wall. When using step by step to clamp and fix the formwork, because step by step can cover The area is relatively small, and as a simple mechanical structure, it is inevitable that there will be deviation or damage during use, resulting in the risk of mold explosion and slurry leakage due to incomplete clamping, which seriously affects the construction progress. , reducing construction efficiency. Therefore, it is very necessary to design a connection device for fixing the structural column formwork and the wall that can reduce the damage to the wall.

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments, and the schematic embodiments and descriptions of the utility model explain the utility model here, but are not intended to limit the utility model.

As shown in Figures 1-6, a connection device for fixing a structural column formwork and a wall according to the utility model includes a movable formwork 1 and a fixed formwork 2, and a cross-section is provided between the movable formwork 1 and the fixed formwork 2. Through the wall screw 6, the movable formwork 1 and the fixed formwork 2 are composed of a first formwork 101 and a second formwork 102 hinged to each other, and the first formwork 101 and the second formwork 102 are all welded and fixed with a reinforcing plate 8;

The reinforcing plate 8 is poured through a mold, and a groove 7 is left on it, and a number of intermittent slots 5 are arranged on the top. The through hole 10, one end close to the hinge of the first template 101 and the second template 102, is on the same surface as the end of the reinforcing plate 8, and the middle of the other end is a semicircle, on which there is a connection hole 11;

The connecting holes 11 are movably connected to the connecting seat 12 at the bottom of the supporting rod 3 and the supporting rod seat 9 through the rotating shaft respectively. The supporting rod 3 is mainly composed of the connecting seat 12 and the connecting rod body 302. The connecting rod body 302 The free end is provided with a threaded end 301. The support rod seat 9 is mainly composed of a top plate 901, a fixed rod 902, a bottom plate 903, a round hole 904 and a connecting seat 12. The bottom plate 903 is fixedly arranged on the top of the connecting seat 12, and the two ends on it are respectively A fixed rod 902 is fixedly arranged, and a top plate 901 is fixedly arranged on the top of the fixed rod 902 , and a circular hole 904 matching the threaded end 301 is left on the top plate 901 .

Both the inner surfaces of the movable formwork 1 and the fixed formwork 2 are coated with a concrete release agent.

A PVC pipe 4 is sheathed on the wall-through screw 6 at a position between the movable formwork 1 and the fixed formwork 2 .

The draw-in groove 5 is an L-shaped structure, and a space is provided for the insertion of a cross bar between its side and the outer side walls of the movable formwork 1 and the fixed formwork 2, which can be used to strengthen the formed structure of the first formwork 101 and the second formwork 102. line angle.

The connecting base 12 is connected to the rotating shaft inside the connecting hole 11 through the round hole on the bottom end. The connecting hole 11 is a rectangular groove, and the two ends of the rotating shaft inside are fixedly arranged on the reinforcing plate 8 .

The length of described PVC pipe 4 is identical with the length of body of wall.

When the utility model is in use, there are two working forms: ① When it is used for the construction column in the middle of the wall, it is only necessary to unfold the first formwork 101 and the second formwork 102 that form the movable formwork 1 and the fixed formwork 2, and Insert the crossbar into the draw-in groove on its outer side to make it a straight board, then fix the movable formwork 1 and the fixed formwork 2 through the wall-through screw 6, and fix the fixed end of the wall-through screw 6 on the fixed formwork 2, The movable end is fixed on the movable formwork 1 by nuts, and the concrete can be poured directly after the adjustment and fixation; ②When it is used at the corner of a corner wall, only the first formwork consisting of the movable formwork 1 and the fixed formwork 2 needs to be placed 101 and the second formwork 102 are folded around the hinge, according to the angle of the corner, the angle formed by the first formwork 101 and the second formwork 102 is the same as the angle of the corner, and then the wall-through screw 6 is first fixed, and then the The threaded end 301 of the support rod 3 is inserted into the round hole 904 at the top of the support rod seat 9, and fixed by a nut, and then the concrete is poured. Therefore, it is necessary to keep the wall-through screw 6 perpendicular to the wall before pouring can be performed; after the pouring is completed and the structural column is formed, the movable formwork 1 and the fixed formwork 2 are removed, and then the wall-through screw 6 is removed, and the PVC pipe 4 is left. Holes can be repaired.

In the utility model, by changing the single formwork of the construction column into two mutually hinged plate structures, and through the cooperative use of the support rod 3 and the support rod seat 9, it can be more compatible with the angle of the corner of the wall, thereby reducing the later stage. At the same time, the two formworks are fixed through the wall screw 6, which can fix the structural column formwork without destroying the wall, thereby reducing the damage to the wall and helping to improve work efficiency. The sheathing of the PVC pipe 4 on the wall screw 6 facilitates the detachment of the wall-through screw 6 in the later stage and reduces the work intensity. In addition, the concrete release agent painted on the inner side of the movable formwork 1 and the fixed formwork 2 can effectively protect the formwork and prolong the life of the formwork. The service life can ensure that the template will not rust when it is placed outdoors or in rainy days, and it can also improve the appearance quality of the construction column.
