Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a shear wall wooden formwork height-adjusting device. Background Art

[0002] During construction, the pouring of concrete for shear walls requires the construction of wall formwork. The wall formwork is generally reinforced by through-wall screws using two-side formwork to ensure that its verticality and height meet the design requirements. The formwork on both sides is fixed with diagonal braces and supports, and reinforced again with through-wall screws. The entire shear wall formwork system is constructed with formwork, steel pipes, and square timbers, which makes the overall weight of the wall formwork relatively large and makes it difficult to move the formwork vertically.

[0003] In the past, traditional construction methods mostly used one worker to lift the formwork with a crowbar and then insert a pad, while another worker observed the elevation of the wall panel and the beam bottom plate, and the two parties slowly cooperated to adjust them. This required two people to make adjustments at the same time, which was inefficient. Utility Model Content

[0004] The utility model aims to provide a shear wall wooden formwork height-adjusting device to solve the problems raised in the above-mentioned background technology.

[0005] A shear wall wooden formwork height adjustment device comprises a base, a stud is rotatably connected to the base in a vertical direction, the stud can rotate freely relative to the base, an adjusting nut is fixedly connected to the top of the stud, two fixing nuts are threadedly connected to the stud, an L-shaped steel bar is fixedly connected to the fixing nut, the L-shaped steel bar is fixedly connected to the two fixing nuts, and an angle iron is fixedly connected to the L-shaped steel bar.

[0006] Preferably, a square tube is fixedly connected to the base, the square tube is vertically arranged, a scale is engraved on the square tube, and a pointer is provided on the angle iron, and the pointer points to the scale.

[0007] Preferably, the distance between the two fixing nuts is equal to half of the vertical distance of the L-shaped steel bars.

[0008] Preferably, the base comprises a 300MM×300MM square steel plate, a connecting platform is provided on the top of the square steel plate, a step hole which is larger at the bottom and smaller at the top is opened in the connecting platform, a cylindrical stopper is fixedly connected to the bottom end of the stud, the diameter of the stopper is larger than the diameter of the stud, and the bottom end of the stud is rotatably connected to the step hole.

[0009] Furthermore, a slot is provided on the outer side of the angle iron, a vertical slot is provided on the slot, and a T-shaped block is provided on one end of the pointer, and the block is detachably connected to the slot.

[0010] Furthermore, the base is provided with a plurality of through holes.

[0011] Compared with the prior art, the utility model has the following beneficial effects: in the utility model, the studs are connected to the base through the connecting platform thread, and the two nuts threaded on the studs are fixedly connected to the L-shaped steel bars. The bottom of the L-shaped steel bars needs to be inserted into the shear wall wooden formwork and fixedly connected to the shear wall wooden formwork. An angle iron is fixedly connected to the L-shaped steel bars, and the angle iron is matched and clamped at the corner of the shear wall. At this time, an electric wrench is used to rotate the adjusting nut on the top of the stud to rotate the entire stud. The fixing nut threaded on the stud is indirectly connected to the angle iron and is constrained by the angle iron and cannot rotate with the stud. Therefore, the fixing nut will move up and down with the rotation of the stud. The fixing nut moves up and down and then drives the L-shaped steel bars. The bottom of the L-shaped steel bars is fixed to the shear wall wooden formwork. The rotation of the stud will indirectly drive the L-shaped steel bars and the shear wall wooden formwork to move up and down, and then the height adjustment of the shear wall wooden formwork can be achieved.

[0012] There is a pointer detachably connected to the angle iron. The vertically arranged scale on one side of the stud cooperates with the pointer to intuitively display the height adjustment size. There is no need for two people to cooperate in observation, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with specific embodiments and attached Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0018] A shear wall wood formwork height adjustment device, characterized in that it includes a base 1, wherein the base 1 includes a 300MM×300MM square steel plate, and two through holes along the vertical direction are opened on the square steel plate. The through holes can be fixed to the bottom surface by expansion screws to prevent the device from moving during use, thereby affecting the accuracy of the shear wall wood formwork.

[0019] A stud 2 is rotatably connected to the base 1 along the vertical direction, and the stud 2 can rotate freely relative to the base 1. Specifically, a connecting platform 11 is provided on the top of the square steel 6, and a stepped hole with a small upper part and a large lower part is provided in the connecting platform 11. The upper hole diameter of the stepped hole is small and the lower hole diameter is large. A stud 2 is rotatably connected in the stepped hole, and a cylindrical stopper 21 is provided at the bottom end of the stud 2. The diameter of the cylindrical stopper 21 is larger than the diameter of the stud 2. The bottom of the stud 2 is limited by the stepped hole, so that the stud 2 cannot be separated from the stepped hole, but can rotate freely.

[0020] An adjusting nut 22 is fixedly connected to the top of the stud 2, and the adjusting nut 22 is fixed to the top of the stud 2 by welding, so that the user can rotate the entire screw rod by using a common wrench or an electric wrench.

[0021] The stud 2 is threadedly connected with two fixing nuts, and there is a certain distance between the two fixing nuts. An L-shaped steel bar 3 is fixedly connected to the fixing nut, and the distance between the two fixing nuts is equal to half of the vertical distance of the L-shaped steel bar 3. The L-shaped steel bar 3 and the two fixing nuts are fixedly connected by welding. Rotating any one of the fixing nuts will cause the two fixing nuts to connect with the L-shaped steel bar 3 and rotate together, thereby allowing the L-shaped steel bar 3 to rotate up and down around the stud 2. Similarly, a rotation-restricting constraint is imposed on the L-shaped steel bar 3, and the stud 2 is rotated at the same time, so that the L-shaped steel bar 3 can move up and down. Because the angle steel is attached to the corner of the shear wall wooden formwork, the L-shaped steel and the shear wall wooden formwork remain relatively fixed to prevent relative rotation between the two. By rotating the adjusting nut 22, the L-shaped steel can be raised or lowered along the stud 2, and then the pad prepared in advance can be inserted under the shear wall formwork, or the device can be set here, thereby achieving the effect of adjusting the shear wall wooden formwork.

[0022] An angle iron 4 is fixedly connected to the L-shaped steel bar 3. Specifically, the angle iron 4 is fixed to one side of the L-shaped steel bar 3 by welding. The lower part of the angle iron 4 and the L-shaped steel bar 3 extends outward and is inserted into the bottom gap of the shear wall wooden formwork. At this time, the angle iron 4 needs to be tightly engaged with the corner of the shear wall wooden formwork. The engagement of the angle iron 4 with the corner of the shear wall wooden formwork can limit the rotation of the L-shaped steel bar 3. The user uses an electric wrench to rotate the adjusting nut 22, which will drive the entire L-shaped steel bar 3 to move up and down.

[0023] A card slot 41 is provided on the outer side of the angle iron 4, and a card joint is opened vertically in the card slot 41. A T-shaped card block is detachably connected in the card joint. The T-shaped card block is inserted into the card slot 41 and is easy to disassemble. A pointer 5 is fixedly connected to the T-shaped card block. The pointer 5 points to one side in the horizontal direction. A vertically arranged square tube is provided in the direction pointed by the pointer 5. A scale 61 is engraved on the square tube. The pointer 5 moves up and down with the movement of the L-shaped steel bar 3. The pointer 5 cooperates with the scale 61 to intuitively display the specific size of the lifting of the shear wall wooden formwork of the utility model, without the need for a second person to cooperate in observing and adjusting the height, and it is more convenient and simple to use.

[0024] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.

[0025] In the present utility model, "up", "down", "left", "right", "front" and "back" are relative positions used to conveniently describe positional relationships, and therefore cannot be understood as absolute positions to limit the scope of protection.

[0026] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
