Description

Technical Field

[0001] The utility model relates to the technical field of building templates, in particular to an adjustable supporting upright pole for a building template. Background Art

[0002] Building formwork is an important tool for the construction of concrete structure engineering. In cast-in-place concrete structure engineering, formwork engineering generally accounts for 20% to 30% of the cost of concrete structure engineering, 30% to 40% of the engineering labor, and about 50% of the construction period. Formwork technology directly affects the quality, cost and benefits of engineering construction, so it is an important part of promoting the progress of my country's construction technology. Building formwork is a temporary supporting structure, which is made according to design requirements to form concrete structures and components according to the specified position and geometric dimensions, maintain their correct position, and bear the deadweight of the building formwork and the external loads acting on it. The purpose of formwork engineering is to ensure the quality and construction safety of concrete engineering, speed up the construction progress and reduce engineering costs.

[0003] During the installation and pouring process, the formwork needs to be supported by a bracket. The support poles are used to support the floor formwork, but their height cannot be adjusted. Due to errors in on-site construction, the height between floors will vary slightly, and the height of the formwork will also change. Construction workers can only find materials on site and place them at the bottom of the support poles to adjust the height of the support poles to ensure that the support poles support the formwork. In this way, not only is the installation speed slow, but it cannot be fully guaranteed that each support pole plays a supporting role, affecting the quality of formwork installation and ultimately the quality of building pouring. At the same time, because the length of the support poles cannot be adjusted, when encountering floors of different heights, the support poles cannot be used universally, which increases construction costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an adjustable supporting upright for building formwork, which has a simple structure, can adjust the length according to the height of the formwork, is simple and convenient to install and adjust, is reusable, has wide adaptability, and is suitable for large-scale promotion and use.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an adjustable supporting pole for building formwork, including a top plate, a connecting rod, an adjusting rod, and a column. The top surface of the top plate is a plane and contacts the bottom surface of the building formwork. The bottom of the top plate is provided with an internal thread, and the internal thread is detachably screwed to the top of the connecting rod. The bottom of the connecting rod is rotatably clamped to the top of the adjusting rod, and the bottom of the adjusting rod can be adjustably connected to the top of the column. The column is placed on the ground or on a poured concrete roof.

[0006] Preferably, the connecting rod is a columnar structure with a round table at the bottom, and the round table is rotatably engaged with the top of the adjusting rod.

[0007] Preferably, a through hole is provided at the center of the adjusting rod, the upper portion of the through hole is a stepped hole, and the round table is rotatably engaged in the stepped hole.

[0008] Preferably, an internal thread is provided at the lower portion of the through hole, and the internal thread is screwed to the column.

[0009] Preferably, a circle of bosses is provided on the outer side surface of the adjusting rod, and six side elevations of the bosses are sequentially connected to form a regular hexagonal structure.

[0010] The beneficial effects of adopting the above technical solution are:

[0011] 1. In the utility model, the top plate and the connecting rod are connected by threads, which is convenient for disassembly and replacement. The top plate can be changed and replaced according to the actual construction situation to adapt to different construction environments. In addition, the support pole can also be used to block some special-shaped reserved holes, and the scope of use is very wide.

[0012] 2. In the utility model, one end of the adjusting rod is rotatably connected to the connecting rod, and the other end is screwed to the column through a thread. When the supporting rod needs to be adjusted in height, it is only necessary to rotate the adjusting rod, which can adapt to the support work of floor formworks of different heights. When the supporting rod has applied a supporting force to the floor formwork, if it is necessary to fine-tune the height of the supporting rod, it is only necessary to rotate the adjusting rod, and because the adjusting rod is rotatably connected to the connecting rod, the top plate above will not be affected when the adjusting rod is rotated.

[0013] 3. A hexagonal boss is provided on the adjusting rod, and the adjusting rod can be rotated by using a homemade wrench in conjunction with the six sides of the boss, making operation easier.

[0014] 4. The various components of the utility model can be made into standard parts, mass-produced, and reused, which not only has low production cost, low construction cost, but also convenient construction operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] like Figure 1As shown, the supporting uprights include a top plate 1, a connecting rod 2, an adjusting rod 3, and a column 4. The top surface of the top plate 1 is a plane, which is supported on the bottom surface of the building template.

[0019] In one embodiment of the top plate 1, the top portion of the top plate 1 is a square steel plate, and a round pipe with an internal thread is welded below the square steel plate. At this time, the support pole only plays a supporting role for the floor slab formwork.

[0020] In another embodiment of the top plate 1, the upper part of the top plate 1 is a long steel plate, and a round tube with internal threads is welded below the long steel plate. In this case, the support pole can be supported at the gap between the two floor slab templates, and the long steel plate just blocks the template gap to prevent concrete leakage. The support pole not only plays a supporting role, but also plays a blocking role.

[0021] Sometimes, some reserved holes are encountered at the construction site, and the reserved holes can be sealed by replacing the top plate 1 .

[0022] The connecting rod 2 can be made of a round tube, and an external thread is set at the top of the round tube, which is screwed with the internal thread of the top plate 1. A section of round steel is welded at the bottom of the connecting rod 2, and the outer diameter of the round steel is larger than the outer diameter of the round tube. The adjusting rod 3 can be made of a round tube, and a cylinder is welded at the top of the round tube. A hole for accommodating the round steel is set in the cylinder, and the inner diameter of the hole is larger than the inner diameter of the through hole of the cylinder. The round steel at the bottom of the connecting rod 2 is just clamped in the hole and can rotate in the hole.

[0023] The lower part of the adjusting rod 3 is provided with an internal thread, which is screwed with the external thread on the upper part of the column 4. The adjusting rod 3 is rotated to adjust the screw connection length between the column 4 and the adjusting rod 3, and finally the height of the entire supporting column is adjusted.

[0024] A circle of bosses is provided on the outer side of the adjusting rod 3, and the six side elevations of the bosses are connected in sequence to form a regular hexagonal structure, and the homemade wrench is adapted to the six sides of the bosses. When adjusting the height, the homemade wrench clamps the two relatively parallel sides of the bosses to rotate the adjusting rod 3.

[0025] In summary, the utility model has a simple structure, is very practical, can be used for multiple purposes, and is suitable for large-scale promotion.

[0026] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this.
