Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a highly applicable template reinforcement device with adjustable size. Background Art
[0002] During construction, cast-in-place concrete components often experience formwork deformation and cracking due to loose formwork reinforcement, excessive concrete pouring, or excessive single-time concrete pouring. This phenomenon, commonly known as "form bulging or bursting," negatively impacts project safety, quality, and cost control.
[0003] The commonly used technical methods to prevent formwork deformation and cracking are to use tie rods or step-by-step tightening. However, tie rods require holes to be drilled in the beam and column formwork, making the formwork difficult to reuse. After the formwork is removed, the rods must be removed and the concrete components repaired, resulting in a poor appearance. While step-by-step tightening does not damage the formwork or components, its effective clamping size is small, making it unsuitable for large-section concrete components. Utility Model Content
[0004] The purpose of the utility model is to provide a highly applicable formwork reinforcement device with adjustable size, so as to solve the technical problems of formwork expansion and explosion caused by loose formwork reinforcement, too fast concrete pouring or too much single pouring volume.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] A highly adaptable formwork reinforcement device with adjustable size comprises a reinforcement formwork, a square beam, a wedge-shaped plate and a support formwork; the reinforcement formwork is clamped to the outside of the support formwork, and a concrete structure is inserted into the support formwork;
[0007] The reinforcement template includes a fixed reinforcement plate and a sliding reinforcement plate, wherein the fixed reinforcement plate is a wedge-shaped steel plate with reinforcement plate bolt holes provided at the bottom of the fixed reinforcement plate, and the sliding reinforcement plate is a wedge-shaped steel plate welded on the short square tube;
[0008] The square beam is a steel square beam, and the side walls around one end of the square beam are all provided with square holes, and the square holes on the adjacent two sides are arranged alternately, and the square holes on the opposite sides are arranged symmetrically. The other end of the square beam is provided with a beam end opening on the upper side, and beam bolt holes are provided on the steel plate side walls on both sides of the opening edge;
[0009] The wedge plate is a wedge-shaped steel plate, and reserved pin holes are evenly opened on the wedge steel plate along the center line.
[0010] Preferably, the fixed reinforcement plate is inserted into the beam end opening reserved at the right end of the square beam and fixed with bolts at the bottom; the sliding reinforcement plate sleeves the short square beam on the left end of the square beam, and is inserted into the reserved square hole through the wedge plate and fixed with pins.
[0011] Preferably, the height between the top of the fixed reinforcement plate and the upper end of the square beam is equal to the height between the top of the sliding reinforcement plate and the upper end of the square beam.
[0012] Preferably, the wedge-shaped plate is inserted into the square beam at a position determined according to the position of the sliding reinforcement plate, and is fixed by inserting a pin into a reserved pin hole on the wedge-shaped plate.
[0013] Preferably, the bolts connecting the fixed reinforcement plate and the square beam are hexagonal bolts.
[0014] Beneficial effects of the utility model:
[0015] (1) By setting fixed reinforcement plates, sliding reinforcement plates and square beams, the fixed reinforcement plates are fixed to the square beams by bolts, and the sliding reinforcement plates can be freely adjusted along the direction of the square beams, so as to adapt to the reinforcement of structural formwork with different cross-sectional widths. In addition, the reinforcement formwork can be customized in different lengths according to the height and other dimensions of the structural beams, and different types of reinforcement devices can be selected according to the needs. It has high adaptability and can effectively achieve reliable reinforcement of concrete component formwork with different cross-sectional sizes without damaging the integrity of the formwork and the structure.
[0016] (2) When the reinforcement device is used, the wedge plate is inserted after the size is adjusted and the pin is inserted into the reserved hole. When dismantling, the pin is pulled out and the wedge plate is taken out to recycle the template reinforcement device. The installation and dismantling is convenient and the operation difficulty is low, which significantly shortens the construction and installation time;
[0017] (3) When in use, the present invention can relatively completely clamp the support formwork on both sides of the structure, so that the support formwork is evenly stressed, avoiding bending moments caused by uneven stress on conventional reinforcement tools, and can be used to reinforce the support formwork of large-volume concrete structures; at the same time, the present invention does not need to destroy the support formwork and the concrete structure, thereby ensuring the integrity of the concrete structure and avoiding stress concentration on the support formwork, which significantly improves the safety and construction quality of the concrete structure.
[0018] (4) It is made of an all-steel structure, which does not require cutting or bending during the process. It can be recycled and reused after use, saving construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] See also Figures 1-10 As shown, the utility model is a highly applicable formwork reinforcement device with adjustable size, comprising a reinforcement formwork 1, a square beam 2, a wedge plate 3, a bolt 4, and a pin 5;
[0033] Among them, Figure 2 and Figure 3 As shown, the reinforcement template 1 includes a fixed reinforcement plate 11 and a sliding reinforcement plate 12, wherein the fixed reinforcement plate 11 is a wedge-shaped steel plate with reinforcement plate bolt holes 13 reserved at the bottom of the fixed reinforcement plate 11; the sliding reinforcement plate 12 is a wedge-shaped steel plate welded on a short square tube 14.
[0034] like Figure 4 and Figure 5 As shown, the square beam 2 is a steel square beam, with a beam end opening 21 reserved on the upper side of the right end, and beam bolt holes 22 reserved at the bottom of the steel plates on both sides of the beam end opening 21; square holes 23 are reserved around the left end of the steel square beam, and the spacing between the square holes 23 is about 5 cm, wherein the square holes 23 on the adjacent two sides are staggered, and the square holes 23 on the opposite sides are symmetrically arranged to ensure that the device fully reinforces the supporting formwork 7.
[0035] like Figure 6 As shown, the wedge plate 3 is a wedge-shaped steel plate, and pin holes 31 are evenly reserved along the center line of the steel plate, and the spacing between the holes is 1 cm.
[0036] Further, such as Figure 7-10 As shown, the fixed reinforcement plate 11 is inserted into the end opening 21 reserved at the right end of the square beam 2 and fixed at the bottom with a bolt 4; the sliding reinforcement plate 12 puts the short square tube 14 on the left end of the square beam 2, adjusts the size of the sliding reinforcement plate 12 according to actual needs, and inserts the reserved square hole 23 through the wedge plate 3 and fixes it with a pin 5.
[0037] Further, such as Figure 2-3 As shown, the fixed reinforcement plate 11 and the sliding reinforcement plate 12 need to be the same length to ensure that the external force is evenly applied to the support formwork 7 during construction. The length of the fixed reinforcement plate 11 and the sliding reinforcement plate 12 can be customized according to actual needs.
[0038] Further, such as Figure 7-10 As shown, the position of the wedge plate 3 to be inserted into the square beam 2 needs to be determined according to the position of the sliding fixing plate 12. After insertion, a hammer is used to hit the tail to make the reinforcement template 1 tightly clamp the template 7, and the pin 5 is inserted into the reserved pin hole 31 of the wedge plate to fix it.
[0039] In this embodiment, if Figure 1 As shown, the fixing bolts 4 for fixing the reinforcement plate are hexagonal bolts.
[0040] During the specific implementation, first select the reinforcement template 1 of appropriate size, install the fixed reinforcement plate 11 on the square beam 2 and tighten the bolts 4, then insert the short square tube 14 of the sliding reinforcement plate 12 into the square beam 2, adjust the position of the sliding reinforcement plate 12 to clamp the reinforcement templates 1 on both sides on the supporting template 7, then insert the wedge plate 3 and use a hammer to tightly clamp the reinforcement template 1 on the template 7, and finally use the pin 5 to fix the position of the wedge plate 3.
[0041] When using the present invention, after the sliding reinforcement plate 12 is positioned, select the reserved square hole 23 of the reinforcement template 1 that does not cover more than 1 / 2 of the area covered by the short square hole 14. Do not select the uncovered reserved square hole 23 and insert the wedge plate 3. If the insertion direction of the wedge plate 3 is parallel to the reinforcement template 1, Figure 7 and Figure 8 As shown, it needs to be inserted from the bottom of the structure upwards.
[0042] After the entire construction is completed, the pin 5 is removed first and then the wedge plate 3 is taken down, and the utility model can be disassembled and reused.
[0043] The utility model has few components, simple structure, easy construction, and convenient installation and disassembly. The support formwork 7 of concrete structures 6 of different sizes can be reinforced by adjusting the reinforcement formwork 1. At the same time, the support formwork 7 on both sides of the clamping structure can be relatively complete when in use, so that the support formwork 7 is evenly stressed, avoiding bending moments caused by uneven stress of conventional reinforcement tools, and can be used to reinforce the support formwork 7 of large-volume concrete structures 6. At the same time, the utility model does not need to destroy the formwork and structure, thereby ensuring the integrity of the structure and avoiding stress concentration in the formwork, and significantly improving the safety of the structure and the construction quality.
[0044] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
