Description

TECHNICAL FIELD

[0001] The utility model relates to building construction tool technical field especially relates to a beam mould clamp. BACKGROUND

[0002] In the process of concrete pouring construction, a mold needs to be built to restrict the concrete, and after it solidifies, a specific shape is formed. For the formation of the roof beam, three wooden boards are usually used to form the shape of the beam, and the concrete is poured into the mold formed by the wooden boards. After the concrete solidifies, the roof beam will naturally form. The concrete is a flowable liquid substance at the initial stage of pouring, and has a large extrusion force on the mold. Therefore, the mold needs to be supported during pouring, that is, a clamp is usually used to clamp the left and right sides of the mold.

[0003] For example, a beam formwork clamp is disclosed in a Chinese utility model patent with the authorization announcement date of June 27, 2023 and the authorization announcement number of CN219261744U. The beam formwork clamp includes a horizontal member for placing under the beam formwork, and a plurality of first mounting holes are arranged on the horizontal member in the horizontal direction. The beam formwork clamp also includes two vertical members (i.e. clamping members) arranged vertically, and each of the two vertical members is provided with a second mounting hole corresponding to the first mounting hole in the vertical direction. There are a plurality of second mounting holes arranged vertically. By matching different first mounting holes and second mounting holes, the position of the vertical member relative to the horizontal member can be adjusted, thereby adjusting the distance between the two vertical members, and facilitating the clamping of beams of different thicknesses. The pull structure mounting hole is also arranged on the vertical member. When the height of the beam is high, a pull structure is arranged between the two vertical members to pull the upper end of the clamp to avoid the upper part being opened.

[0004] In the above technical solution, the two vertical members can only be adjusted at a certain distance, which is not flexible enough and has poor universality. In addition, due to the manufacturing precision error, there may be a gap between the manufactured beam mold and the clamp, which may cause the mold to be opened outward and leak when receiving the extrusion of the concrete. In addition, the pull structure mounting hole is also arranged at intervals. In order to meet the pulling force, multiple pull structures may be arranged for the same clamp. Due to the interval arrangement of the pull structure mounting holes on the vertical member, the distance is determined. In the use process of some clamps, the distance between two adjacent pull structures cannot be further reduced, which may result in insufficient pulling force, and thus a new clamp needs to be replaced.

[0026] In order to better understand the technical scheme of the present application, the present application will be described in detail below with reference to the drawings.

[0027] In the embodiment 1 of the beam mold clamp in the present application,

[0028] As shown in Figure 1 and Figure 2 , the beam mold clamp in the present embodiment comprises two split first and second branch clamps, wherein the first branch clamp comprises a first clamping arm 1 and a first connecting arm 2, the first clamping arm 1 is vertically arranged, the first connecting arm 2 is fixedly connected with the first clamping arm 1 and perpendicular to each other, and the first connecting arm 2 is a hollow square tube. The second branch clamp comprises a second clamping arm 3 and a second connecting arm 4, the second clamping arm 3 is vertically arranged, the second connecting arm 4 is fixedly connected with the second clamping arm 3 and perpendicular to each other, the second connecting arm 4 is a hollow square tube, and the second connecting arm 4 is nested with the first connecting arm 2, and the two connecting arms can slide relative to each other.

[0029] The first clamping arm 1 and the second clamping arm 3 have the same structure, and the structure of the first clamping arm 1 will be introduced as an example. As shown in Figure 3 , the first clamping arm 1 is formed by bending a steel plate, wherein the first clamping arm 1 has a first clamping plate 11 for clamping the beam mold 7 and a first reinforcing plate 12 perpendicular to the first clamping plate 11 and extending away from the beam mold 7, one side of the first reinforcing plate 12 is connected to the first connecting arm 2 connected to the first clamping arm 1, thereby facilitating the fixed connection of the first clamping arm 1 and the first connecting arm 2. A first reinforcing flange 13 is also formed at the end of the first reinforcing plate 12 away from the first clamping plate 11. In order to maintain the connection strength between the first clamping arm 1 and the first connecting arm 2, the first reinforcing plate 12 is in the shape of a right trapezoid, and the first reinforcing flange 13 is also arranged obliquely. As shown in Figure 4 , the second clamping arm 3 also comprises a second clamping plate 31, a second reinforcing plate 32 and a second reinforcing flange 33, and the structure of the second clamping arm 3 is the same as that of the first clamping arm 1, and the size is also the same, which will not be repeated here. Of course, if only the clamping function is needed, the first clamping arm can also be provided as a steel pipe with a pull structure mounting hole extending in the vertical direction provided on the steel pipe, and the pull structure mounting hole is a long hole.

[0030] The first clamping plate 11 is provided with a long-hole-shaped counter-pulling structure mounting hole 53, which improves the versatility of the clamp. However, the opening of the hole reduces the strength of the first clamping plate 11 and is not conducive to transmitting a large torque during clamping. The first clamping plate 11 is folded at an end away from the first reinforcing plate 12 to form a first limiting protrusion 14. The first limiting protrusion 14 extends in the vertical direction, and the first limiting protrusion 14 is arranged in the vertical direction corresponding to the counter-pulling structure mounting hole 53. The length of the first limiting protrusion 14 is greater than the length of the counter-pulling structure mounting hole 53. In this way, the structure of the first clamping plate 11 is strengthened within the coverage range of the counter-pulling structure mounting hole 53, and the structural strength is greatly improved with less structure. In addition, since the first limiting protrusion 14 is arranged towards the beam mold 7, it can also play a role in clamping the beam mold 7 to prevent the beam mold 7 from moving relative to the clamp during use. At the same time, since the first limiting protrusion 14 and the first clamping plate 11 are integrally formed and have higher structural strength. The second clamping plate 31 is also provided with a second limiting protrusion 34 which has the same structure as the first limiting protrusion 14 on the first clamping plate 11. Of course, in other embodiments, the first clamping plate and the first limiting protrusion can be connected by welding. The first limiting protrusion can not only be located at the end of the first clamping plate, but also be provided on the surface of the first clamping plate. Alternatively, in other embodiments, the first limiting protrusion can not be provided on the first clamping plate, and the thickness of the first clamping plate can be increased to improve the strength. However, at this time, the weight of the first clamping plate can be relatively large, which is not suitable for manual handling.

[0031] The counter-pulling structure mounting hole 53 needs to be threaded with a counter-pulling screw 51 to facilitate the connection of the first clamping arm 1 and the second clamping arm 3. During threading, interference cannot occur. The first reinforcing flange 13 is in an opposite position to the first clamping plate 11, so the first reinforcing flange 13 cannot interfere during threading of the counter-pulling screw 51. The extension length of the first reinforcing flange 13 is relatively short. The projection of the reinforcing flange on the clamping plate is staggered with the counter-pulling structure mounting hole 53, so that the counter-pulling screw 51 can be smoothly threaded. Of course, in other embodiments, a through hole can be provided on the first reinforcing flange to allow the counter-pulling screw to pass through, facilitating the threading of the counter-pulling screw.

[0032] As Figure 2 , Figure 3 and Figure 4As shown, the first connecting arm 2 and the second connecting arm 4 are nested with each other, the first connecting arm 2 and the second connecting arm 4 are square tubes with different sizes, which can realize mutual movement, and at the same time, the square tube can also prevent the first connecting arm 2 and the second connecting arm 4 from rotating with each other in the process of movement, thereby keeping the correspondence of the first clamping arm 1 and the second clamping arm 3. The size of the first connecting arm 2 is larger than that of the second connecting arm 4, and specifically, the inner hole of the first connecting arm 2 is just fitted with the outer periphery of the second connecting arm 4, which facilitates the movement of the two.

[0033] A lead screw 61 is also arranged between the first connecting arm 2 and the second connecting arm 4, a first blocking plate (not shown in the figure) is arranged at the end of the first connecting arm 2 away from the second connecting arm 4, one end of the lead screw 61 penetrates through the first blocking plate and is exposed outside the first connecting arm 2, and a force applying part 62 is further arranged on the one end of the lead screw 61 to facilitate the application of torque to the lead screw 61 and control the rotation of the lead screw 61. The other end of the lead screw 61 penetrates into the cavity of the first connecting arm 2, and a nut 41 is fixedly arranged in the second connecting arm 4, the lead screw 61 and the nut 41 are assembled together, and since the nut 41 is fixed with the second connecting arm 4 and the second connecting arm 4 cannot rotate with the first connecting arm 2, when the rotation of the lead screw 61 is controlled by the force applying part 62, the nut 41 will move relative to the lead screw 61, converting the rotation of the lead screw 61 into the straight movement of the nut 41, so as to make the first connecting arm 2 and the second connecting arm 4 move away from each other or move close to each other. In order to prevent the lead screw 61 from coming out, a anti-extrusion nut 63 is further welded at the end of the lead screw 61 located in the second connecting arm 4, when the anti-extrusion nut 63 moves to the nut 41, the lead screw cannot continue to move due to the obstruction of the anti-extrusion nut 63, thereby preventing the lead screw 61 from coming out. At the same time, a second blocking plate is further arranged at the end of the second connecting arm 4 away from the first connecting arm 2, thereby facilitating the blocking of the internal space of the second connecting arm 4 and reducing the risk of water entering the first connecting arm 2 and the second connecting arm 4 in the clamp. Of course, in other embodiments, the first connecting arm and the second connecting arm can be circular tubes, and at this time, a rotation stopping structure needs to be arranged in the first connecting arm and the second connecting arm. Alternatively, in other embodiments, the structure of the first connecting arm and the second connecting arm can be reversed, that is, the size of the first connecting arm is smaller than that of the second connecting arm, and the second connecting arm is inserted into the second connecting arm.

[0034] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
