Technical Field

[0001] This utility model relates to the technical field of adjustable building formwork support devices, specifically an adjustable building formwork support device. Background Technology

[0002] Construction formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components according to specified positions and geometric dimensions, maintain their correct position, and bear the self-weight of the formwork and external loads acting on it. Construction formwork serves as the mold and support for concrete pouring and shaping. Based on material properties, it can be classified into construction formwork, plywood, film-faced plywood, multi-layer plywood, double-sided adhesive-coated formwork, and double-sided film-faced formwork, etc. Based on construction process conditions, construction formwork can be classified into cast-in-place concrete formwork, pre-assembled formwork, large formwork, and step-up formwork, etc.

[0003] Currently available adjustable formwork support devices have low strength, and long-term use will cause the support device to bend, making it unable to support the formwork and posing a significant safety hazard. Furthermore, they are not easy to adjust and cannot be adjusted according to the height of the formwork, which will affect the later support of the formwork.

[0004] Therefore, it is necessary to provide an adjustable building formwork support device to solve the above-mentioned technical problems. The information disclosed in this background section is only intended to enhance the understanding of the overall background of this utility model, and is not necessarily to be regarded as an admission or to imply in any way that the information constitutes prior art known to those skilled in the art.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1-5 An adjustable building formwork support device includes a base block 1, a threaded sleeve 2, a threaded extension rod 3, a jacking pipe 4, and a top support block 5. The upper end of the base block 1 is welded and fixed to the lower end of the threaded sleeve 2. The threaded extension rod 3 is threaded into the inner cavity of the threaded sleeve 2, and its upper end passes through the upper end of the threaded sleeve 2. The upper end of the threaded extension rod 3 is fixed to the lower end of the jacking pipe 4, and the upper end of the jacking pipe 4 is fixed to the lower end of the top support block 5. A fixing sleeve 6 is installed on the upper end of the surface of the threaded sleeve 2. The front and rear sides of the upper end of the fixing sleeve 6 are... The positioning block 7 is installed, and a fixing screw 8 is provided on the front side of the positioning block 7. The back side of the fixing screw 8 extends through the rear side of the threaded extension rod 3 to the rear side of the positioning block 7. The threaded sleeve 2 includes a steel structure material base layer 9, a strength layer 10 and an electroplated anti-corrosion layer 11.

The alloy steel layer 1001 is provided on the inner surface of the carbon alloy layer 1002.

[0027] A locking nut is fitted on the rear side of the surface of the fixing screw 8. First, move the fixing screw 8 out of one side of the threaded extension rod 3, rotate the threaded extension rod 3, and the threaded extension rod 3 will mesh with the threaded sleeve 2 and rotate. The threaded extension rod 3 will drive the top tube 4 to move up and down, and the top tube 4 will drive the top support block 5 to move up.

[0028] The outer side of the positioning block 7 is provided with a through hole that works with the fixing screw 8. The top support block 5 can be moved to a suitable height according to the usage requirements. The threaded extension rod 3 is then fixed by the fixing screw 8 to prevent the threaded extension rod 3 from moving downward and failing to support the template.

[0029] The front side of the threaded extension rod 3 has through holes 2 that cooperate with the fixing screw 8 from top to bottom, and the rear side of the through holes 2 extends to the rear side of the threaded extension rod 3. The alloy steel layer 1001 has excellent performance in resisting impact, extrusion, and material wear, which increases the strength and wear resistance of the threaded extension rod 3 and further extends the service life of the threaded extension rod 3.

[0030] Mounting holes are provided around the top of both the base block 1 and the top support block 5. Through the carbon alloy layer 1002, high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, and high temperature resistance can be obtained, which improves the strength and corrosion resistance of the threaded extension rod 3 and increases the high temperature resistance and rust resistance of the threaded extension rod 3.

[0031] The threaded sleeve 2 is made of the same material as the threaded extension rod 3 and the top pipe 4. With the addition of the electroplated anti-corrosion layer 11, it has excellent acid and alkali resistance, wear resistance and flame retardancy. The threaded sleeve 2 can maintain good mechanical properties even when exposed to harsh conditions for a long time. It also has good corrosion resistance, which increases the corrosion resistance and chemical resistance of the threaded sleeve 2 and extends its service life.

[0032] In use, first move the fixing screw 8 out to one side of the threaded extension rod 3, then rotate the threaded extension rod 3. The threaded extension rod 3 engages with the threaded sleeve 2 and rotates. The threaded extension rod 3 drives the jacking pipe 4 to move up and down, and the jacking pipe 4 drives the top support block 5 to move upward. The top support block 5 can be moved to a suitable height according to the usage requirements. Then, fix the threaded extension rod 3 with the fixing screw 8 to prevent the threaded extension rod 3 from moving downward and failing to support the template. The alloy steel layer 1001 has excellent properties of withstanding impact, extrusion, and material abrasion, increasing the strength and wear resistance of the threaded extension rod 3. The service life of the threaded extension rod 3 is further extended. Through the carbon alloy layer 1002, high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, and high temperature resistance are obtained, which improves the service strength and corrosion resistance of the threaded extension rod 3, and increases its high temperature resistance and rust resistance. Through the setting of the electroplated anti-corrosion layer 11, it has good acid and alkali resistance, wear resistance, and flame retardancy. The threaded sleeve 2 can still maintain good mechanical properties even when exposed to harsh conditions for a long time. At the same time, it also has good corrosion resistance, which increases the corrosion resistance and chemical resistance of the threaded sleeve 2 and extends its service life.
