Description

Technical Field

[0001] The utility model relates to the technical field of construction tools, and more specifically, the utility model is an adjustable support adapted to different beam widths. Background Art

[0002] With the rapid development of society, the construction industry has also accelerated. At present, in the construction field, traditional tension bolts can only be treated with subsequent repair measures. During the repair, the hollows are irregular, the filling material is not dense, the strength is low, the surface is uneven, not smooth, not beautiful, and easy to fall off. The exposed steel bar heads will rust for a long time and the cast body will have rust watermarks, which will cause electrolytic damage to the internal steel bars and produce holes. The holes will cause aging of the concrete and erosion of the building surface due to long-term water seepage, which may cause deformation, cracks and other damage to the concrete, seriously affecting the life of the main body.

[0003] The concrete treated by the traditional tension bolt fixing beam formwork has poor appearance quality, and the chiseling and cutting are time-consuming and labor-intensive. Moreover, if the sealing is not in place after a long time of use, rust will occur, affecting the durability of the concrete. After the concrete is poured, not only is it impossible to remove the screw, but the tension bolts extending out of the beam body make it more difficult to remove the formwork. The steel bars extending out of the beam body need to be cut manually, which wastes a lot of steel and increases the construction cost of the project.

[0004] In order to change this situation, the Chinese utility model patent specification CN 214995994 U published on December 3, 2021 discloses a small-sized concrete beam formwork system reinforcement structure, in which the adjustable combined secondary keel includes a fixed mother splint, a movable sub-splint and a latch plate. The fixed mother splint includes a back corrugated mother plate and an inner tube tube. The inner tube tube is provided with a group of adjustment through holes. The movable sub-splint includes a back corrugated sub-plate and an outer tube tube. The back corrugated mother plate and the back corrugated sub-plate are arranged opposite to each other. The outer tube tube is connected to the inner tube tube from the end where the adjustment through hole of the inner tube tube is located. The outer tube tube can move horizontally on the inner tube tube, and the latch plate is plugged into the first adjustment through hole located on the outside of the outer tube tube. The movable sub-splint can be limited by inserting the matching latch plate into the adjustment through hole of the fixed mother splint, thereby achieving the purpose of reinforcing the beam side formwork. The latch plate is located on the outside of the fixed mother plate. After the latch plate is fully inserted, the lower half will be exposed from under the fixed mother plate. When construction workers walk by below, it is easy to hit the latch plate, causing the adjustable combined secondary purlin to fall off as a whole, affecting the safety of construction workers. In addition, the adjustable combined secondary purlin was originally installed on the lower side of the floor panel, and the latch plate needs to be inserted with downward force, which is also easy to cause the adjustable combined secondary purlin to fall off, making installation inconvenient. Utility Model Content

[0005] In order to solve the technical problems existing in the background technology, the utility model innovatively provides an adjustable support that can adapt to different beam widths. It can not only adapt to pre-set beams of different widths, but also avoid the use of tension bolts. Secondly, it has the advantages of fast installation speed, simple operation, low construction difficulty, convenient adjustment, safety and reliability.

[0006] To achieve the above technical objectives, the utility model discloses an adjustable support adapted to different beam widths, comprising a fixed splint, a movable splint and an adjusting screw, the fixed splint comprising an external tube and a first clamping jaw, a gasket is fixed to the right end of the external tube, a through hole is provided in the center of the gasket, the first clamping jaw is vertically fixed to the upper side of the right half of the external tube, the movable splint comprises an inner tube and a second clamping jaw, the inner tube is inserted into the external tube from the left, the first clamping jaw is vertically fixed to the upper side of the left half of the inner tube, and the adjusting screw passes through the through hole of the gasket from right to left and is threadedly connected to the right end of the inner tube.

[0007] Furthermore, the utility model provides an adjustable support adapted to different beam widths, wherein an adjusting nut is welded to the right end of the inner tube, and the adjusting screw is threadedly connected to the adjusting nut.

[0008] Furthermore, the utility model provides an adjustable support adapted to different beam widths, wherein the outer tube and the inner tube are both rectangular tubes.

[0009] Furthermore, the utility model provides an adjustable support adapted to different beam widths, wherein the gasket is a rectangular steel gasket, and the surface area of ​​the rectangular steel gasket is larger than the cross-sectional area of ​​the external tube.

[0010] Furthermore, the utility model provides an adjustable support adapted to different beam widths, wherein the first clamp and the second clamp are both made of C-shaped channel steel, the side surface of the C-shaped channel steel is a right-angled trapezoid, and the two right-angled sides of the first clamp and the second clamp are arranged opposite to each other.

[0011] Furthermore, the utility model provides an adjustable support adapted to different beam widths, wherein an adjusting nut is provided at the right end of the adjusting screw.

The adjusting screw can also be used to make the first clamp and the second clamp tightly clamp the beam to form a stable connection. In actual operation, the inner tube only needs to be inserted into the outer tube, and then the adjusting screw is tightened to complete the installation. This assembly method is not only simple and easy, but also greatly improves the installation efficiency, significantly saving construction time and cost. The connection position of the inner tube and the outer tube is designed inside the inner tube. This layout makes the connection structure less susceptible to damage from external collisions, thereby greatly reducing the safety hazards of construction workers. This connection method does not require the use of tension bolts, so it also avoids the problem of long-term water seepage caused by holes left by the tension bolts.

By adopting the connection method of the inner tube and the outer tube, not only can the integrity and seismic resistance of the beam be ensured, but also the service life of the building can be extended to a certain extent.

[0017] The following is a detailed explanation and description of an adjustable support for different beam widths of the utility model in conjunction with the accompanying drawings of the specification.

[0018] like Figure 1-4 As shown, the utility model discloses an adjustable support adapted to different beam widths, comprising a fixed splint 1, a movable splint 2 and an adjusting screw 3, the fixed splint 1 comprising an external tube 11 and a first clamping jaw 12, a gasket 13 is fixed to the right end of the external tube 11, a through hole is provided in the center of the gasket 13, the first clamping jaw 12 is vertically fixed to the upper side of the right half of the external tube 11, the movable splint 2 comprises an inner tube 21 and a second clamping jaw 22, the inner tube 21 is inserted into the outer tube 11 from the left side, the first clamping jaw 12 is vertically fixed to the upper side of the left half of the inner tube 21, and the adjusting screw 3 passes through the through hole of the gasket 13 from right to left and is threadedly connected to the right end of the inner tube 21.

[0019] In practical applications, the position of the inner tube 21 in the outer tube 11 can be controlled by rotating the screw, and then its length can be adjusted to adapt to beams of different widths. The first clamp 12 and the second clamp 22 can also be used to tightly clamp the beam by adjusting the screw 3 to form a stable connection. In actual operation, the inner tube 21 only needs to be inserted into the outer tube 11, and then the adjusting screw 3 is tightened to complete the installation. This assembly method is not only simple and easy, but also greatly improves the installation efficiency, significantly saving construction time and cost. The connection position of the inner tube 21 and the outer tube 11 is designed inside the inner tube 21. This layout makes the connection structure less susceptible to damage from external collisions, thereby greatly reducing the safety hazards of construction workers. This connection method does not require the use of tension bolts, and therefore avoids the problem of long-term water seepage caused by holes left by tension bolts. Long-term water seepage will not only cause aging of the concrete, but may also cause erosion damage and damage the surface of the building. By adopting the connection method of the inner tube 21 and the outer tube 11, not only can the integrity and seismic resistance of the beam be ensured, but also the service life of the building can be extended to a certain extent.

[0020] In one embodiment of the utility model, an adjusting nut 23 is welded to the right end of the inner tube 21, and the adjusting screw 3 is threadedly connected to the adjusting nut 23. The adjusting nut 23 does not need to be specially customized, and it only needs to ensure that it matches the adjusting screw 3. The discarded nuts can be flexibly selected on the construction site for secondary use, which not only reduces the cost but also reflects the concept of environmental protection. Secondly, the outer tube 11 and the inner tube 21 are both rectangular tubes. The use of rectangular tubes can limit the axial rotation of the inner tube 21 after the outer tube 11 and the inner tube 21 are assembled, thereby ensuring the stability of the entire connection structure. In addition, the gasket 13 is a rectangular steel gasket 13, and the surface area of ​​the rectangular steel gasket 13 is greater than the cross-sectional area of ​​the outer tube 11. Under the action of pressure, the adjusting screw 3 can generate sufficient locking force, further ensuring the stability of the connection between the outer tube 11 and the inner tube 21. At the same time, this design also ensures that the first clamping jaw 12 and the second clamping jaw 22 can apply sufficient clamping force, thereby firmly fixing the clamped beam body. In order to ensure the strength of the first clamping jaw 12 and the second clamping jaw 22, the first clamping jaw 12 and the second clamping jaw 22 are both made of C-shaped channel steel, the side of the C-shaped channel steel is a right-angled trapezoid, and the two right-angled sides of the first clamping jaw 12 and the second clamping jaw 22 are arranged opposite to each other. In order to facilitate the rotation of the adjusting screw, an adjusting nut is provided at the right end of the adjusting screw 3.

[0021] In order to more clearly understand how to use the utility model during construction, the following description is made:

[0022] Step 1: Install the main and secondary beam bottom formwork

[0023] (1) Install double steel tube main purlins, install wooden secondary purlins vertically along the main purlins, and lay 15 mm thick plywood on the secondary purlins.

[0024] (2) At the connection between the beam formwork and the column formwork, the effect of the formwork expanding after absorbing water should be considered, and the cutting size should generally be slightly shortened so that the formwork will not be embedded in the concrete after concrete pouring.

[0025] (3) At the junction between the main beams and between the main and secondary beams, the bottom formwork and side formwork of the main beam or secondary beam are required to be placed on the lining of the intersecting main beam to ensure the tightness of the joint and the rigidity requirements.

[0026] Step 2: Install the main and secondary beam side formwork and the bottom formwork

[0027] (1) After the reinforcement of the primary and secondary beams is tied, install the beam side formwork and slab bottom formwork.

[0028] (2) The panel of the beam side formwork is installed first, and the side formwork panel is pressed against the bottom formwork panel. The elevation of the upper end of the beam side formwork is the same as the elevation of the bottom of the board. Then the small beam ribs and large steel pipe ribs are installed.

[0029] (3) First install the double steel tube main keel on the bottom formwork, then install the wooden secondary keel vertically along the main keel, and lay 15mm thick plywood on the secondary keel.

[0030] Step 3: Template assembly accuracy controls beam width mold installation requirements

[0031] The formwork assembly must be assembled into a whole in strict accordance with the dimensions of the formwork matching drawing. When the formwork is assembled on site, the joints between adjacent panels must be controlled. Clips or wooden squares must be added to the joints of the two panels to prevent leakage. After the formwork is assembled, the adjustable support is inserted into the formwork from bottom to top so that the first clamp 12 and the second clamp 22 are respectively located on both sides of the formwork, and then the adjusting screw 3 is tightened so that the first clamp 12 and the second clamp 22 clamp the formwork. Finally, the formwork is fixed firmly to maintain the overall stability of the formwork, and then grouting is injected into the formwork to complete the casting of the beam.
