Description

Technical Field

[0001] This utility model relates to the technical field of formwork engineering and related fields, and in particular to a steel frame formwork compensation clamp device. Background Technology

[0002] The steel frame (usually welded steel borders and ribs) provides strong structural strength, rigidity, and dimensional stability, ensuring the formwork remains undeformed. The embedded timber (as panels or filler) offers advantages such as relative economy, ease of processing (drilling, cutting), good contact with concrete (reducing air bubbles), and relatively light weight. This combined system is widely used in large-scale formwork construction for cast-in-place concrete structures such as walls, columns, and beams, especially in large-scale residential, commercial, and public building projects. During demolding, the timber inevitably suffers from physical impacts (pry bars, hammering), concrete adhesion and peeling, and expansion and contraction cycles in humid environments. Its edges and corners are particularly prone to wear, compression deformation, and even breakage. With increased reuse, the actual dimensions of the timber (especially its thickness and the dimensions of the edges in contact with the steel frame) gradually decrease. This results in gaps between the timber and the sturdy, undeformed steel frame.

[0003] The presence of gaps can cause the following problems: During concrete pouring, cement slurry can seep out from the gaps between the timber and the steel frame, leading to serious quality defects on the concrete surface such as honeycombing, pitting, sand streaks, and even exposed rebar. Gaps can also cause slight displacement or tilting of the timber under the lateral pressure of the concrete, affecting the dimensional accuracy and verticality of the formed components. If the gaps are too large, resulting in severe slurry leakage or substandard surface quality, even if the main timber structure is intact, it must be replaced prematurely, increasing material costs.

[0004] Existing solutions mostly involve: frequent replacement of timber, which is costly, wasteful of materials, inconsistent with green construction principles, and time-consuming. Adding shims to the gaps, temporarily inserting wood or metal sheets, is cumbersome, makes it difficult to ensure even stress and flatness, and the shims themselves may loosen and fall off, resulting in inconsistent effectiveness and low efficiency. Replacing the entire timber panel is also costly and may introduce new deformation risks due to incompatibility between the new timber and the old steel frame or changes in the moisture content of the new timber. Utility Model Content

[0005] In view of this, and to solve the above problems, the purpose of this utility model is to provide a steel frame formwork compensation clamp device, comprising:

[0006] Mounting base, pin, movable hook, fixed hook;

[0007] The upper surface of the mounting base extends through to the lower surface and is provided with a slot. Several adjustment grooves are formed on the inner walls of the slot in both length directions.

[0008] The outer edge of the pin extends outward to form a limiting edge. The pin is inserted into the slot, and the limiting edge can be engaged with any two opposing adjustment grooves.

[0009] A through groove is provided on one side of the mounting base, the through groove is connected to the slot, one end of the movable hook is slidably installed in the through groove, and one end of the movable hook can extend into the slot, and the pin can press the movable hook to fix the movable hook.

[0010] The fixed hook is installed on one side of the mounting base, and the movable hook is arranged opposite to the fixed hook.

[0011] In the aforementioned steel frame formwork compensation clamp device, the width of the pin gradually decreases from top to bottom.

[0012] In the above-mentioned steel frame template compensation clamp device, two sliding grooves are opened on the inner walls of the through groove in two length directions, and two sliding blocks are provided on the outer wall of the through groove for the movable hook to slide. The movable hook slides on the two sliding grooves through the two sliding blocks.

[0013] In the aforementioned steel frame formwork compensation clamp device, the two grooves and the two sliding blocks are all rectangular in cross-section along the horizontal direction.

[0014] In the aforementioned steel frame formwork compensation clamp device, both the movable hook and the fixed hook are formed by a single bend, and the bending directions of the movable hook and the fixed hook are opposite to each other.

[0015] In the aforementioned steel frame formwork compensation clamp device, both the movable hook and the fixed hook are inclined relative to the mounting base, and the inclination directions of the movable hook and the fixed hook are opposite to each other.

[0016] In the aforementioned steel frame formwork compensation clamp device, the mounting base, the pin, the movable hook, and the fixed hook are all made of steel.

[0017] In the above-mentioned steel frame formwork compensation clamp device, the fixing hook and the mounting base are integrally formed.

[0018] The positive effects of the above technical solution compared with the existing technology are:

[0019] This invention provides a steel frame formwork compensation clamp device. Through the cooperation of a pin and a movable hook, the distance between the movable and fixed hooks can be adjusted, making it suitable for timber of different sizes and gaps.

It also effectively prevents grout leakage, ensuring the flatness, smoothness, and dimensional accuracy of the concrete surface, reducing quality defects and repair costs. Compared to replacing timber or temporarily adding shims, this method is faster, more reliable, and standardized, reducing rework. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0025] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0026] like Figures 1 to 3 As shown, a preferred embodiment of a steel frame formwork compensation clamp device is illustrated, comprising: a mounting base 1, a pin 2, a movable hook 3, and a fixed hook 4.

[0027] The upper surface of the mounting base 1 extends through to the lower surface and has a slot 5. The inner walls of the slot 5 in both length directions have several adjustment grooves 6. The outer edge of the pin 2 extends outward to form a limiting edge 7. The pin 2 is inserted into the slot 5 and the limiting edge 7 can be locked against any two opposite adjustment grooves 6. A through groove 8 is provided on one side of the mounting base 1. The through groove 8 communicates with the slot 5. One end of the movable hook 3 is slidably installed in the through groove 8 and can extend into the slot 5. The pin can press the movable hook 3 to fix it. A fixed hook 4 is installed on one side of the mounting base 1, and the movable hook 3 and the fixed hook 4 are arranged opposite to each other.

[0028] In actual use, the movable hook 3 and the fixed hook 4 are embedded into the groove of the steel frame 9 to ensure that the movable hook 3 and the fixed hook 4 fit the steel frame. Then, the pin 2 is inserted into the corresponding adjustment groove 6 in the slot 5, and the upper end of the pin 2 is struck with the appropriate tool to make the pin 2 press the movable hook 3, thereby limiting and fixing the movable hook 3. The setting of the limiting edge 7 also increases the force-bearing area of ​​the upper end of the pin 2, making it easier to strike the pin 2.

[0029] Based on the above, this utility model also has the following embodiments:

[0030] Furthermore, in a steel frame template compensation clamp device, the width of the pin 2 gradually decreases from top to bottom. Furthermore, the cross-section of the pin 2 along the vertical direction is an inverted right triangle, giving the upper end of the pin 2 a larger flat surface for easier striking of the upper end, and the lower end of the pin 2 has a smaller width, making it easier to insert the pin 2 into the slot 5, thereby pressing the movable hook 3.

[0031] Furthermore, in a steel frame template compensation clamp device, two sliding grooves are formed on the inner walls of the through groove 8 in two length directions. A sliding block is provided on the outer wall of the through groove 8, and the movable hook 3 slides in the two sliding grooves via the sliding block. Specifically, the sliding block and sliding grooves are provided so that the movable hook 3 slides in the through groove 8, ensuring that the movable hook 3 will not fall out of the through groove 8 even when not pressed and fixed by the pin 2.

[0032] Furthermore, in a steel frame template compensation clamp device, the cross-sections of the two sliding grooves and the two sliding blocks along the horizontal direction are all rectangular. Furthermore, the cross-sections of the two sliding grooves and the two protrusions along the horizontal direction are all rectangular, which prevents the protrusions from wobbling when moving within the sliding grooves and ensures the stability of the movable hook 3 during movement.

[0033] Furthermore, in a steel frame template compensation clamp device, both the movable hook 3 and the fixed hook 4 are formed by a single bend, and the bending directions of the movable hook 3 and the fixed hook 4 are arranged opposite to each other. Specifically, the bent portions of the movable hook 3 and the fixed hook 4 are fixed within the grooves of the steel frame 9.

[0034] Furthermore, in a steel frame template compensation clamp device, both the movable hook 3 and the fixed hook 4 are inclined relative to the mounting base 1, and the inclination directions of the movable hook 3 and the fixed hook 4 are opposite to each other. Specifically, the inclined movable hook 3 and the fixed hook 4 are better clamped in the groove of the steel frame 9.

[0035] Furthermore, in a steel frame formwork compensation clamp device, the mounting base 1, pin 2, movable hook 3, and fixed hook 4 are all made of steel. Furthermore, the use of steel for the mounting base, pin 2, movable hook 3, and fixed hook 4 extends their service life.

[0036] Furthermore, in a steel frame formwork compensation clamp device, the fixing hook 4 and the mounting base 1 are integrally formed. Furthermore, the integral formation of the fixing hook 4 and the mounting base 1 provides greater stability.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
