[0001] The invention relates to the technical field of construction engineering, in particular to an auxiliary tool for placing a steel bar pad. Background Art
[0002] During the foundation and base construction phase of the construction project, according to the design requirements, the bottom slab waterproof layer adopts the pre-laid reverse bonding process (no protective layer), and the raft steel bars are tied on top of the waterproof layer. When the raft steel bars are tied, concrete pads need to be placed to ensure the thickness of the steel bar protective layer. To place the pads, the raft steel bars need to be tilted up, and then the pads can be inserted between the waterproof layer and the raft steel bars. However, during the construction process, it was found that the operators used various tools, such as steel bars, ordinary crowbars, etc. to pry the raft steel bars. At the same time, the waterproof layer became the force-bearing surface at the bottom of the tool, resulting in varying degrees of damage to the waterproof layer, which had great defects in terms of ease of operation and protection of the waterproof layer.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] The following embodiments may be understood as explaining a local structure of the present invention individually, or may be understood as explaining a larger structure of the present invention through a combination of multiple embodiments.
[0023] An auxiliary tool for placing steel bar pads, such as Figure 1-5 As shown, it includes a steel bar 1, a flat steel 2, and a prying angle control mechanism. The lower part of the flat steel 2 is bent into a first arc structure 3 that bends forward and upward. The steel bar 1 is welded to the front surface of the flat steel 2. The bottom of the steel bar 1 is a second arc structure that is the same as the first arc structure 3. The second arc structure is welded to the middle part of the inner surface of the first arc structure 3 as a whole. The rear surface of the flat steel 2 is provided with a prying angle control mechanism.
[0024] like Figure 1-3 As shown, wing plates 11 are respectively provided at both ends of the lower part of the flat steel 2 , and the wing plates 11 are bent inwardly to form a third arc structure 10 . The third arc structure 10 prevents the two ends of the bottom of the flat steel 2 from damaging the waterproof layer 14 .
[0025] like Figure 3 As shown, a groove 12 is provided in the middle of the inner end of the wing plate 11. The groove is designed to facilitate the bending and forming of the third arc structure.
[0026] like Figure 1 , 2 As shown, the steel bar 1 is a threaded steel bar, and the bottom end of the steel bar 1 extends horizontally forward to form a horizontal section 4, and the horizontal section 4 is welded to the top of the end of the first arc structure 3. The threaded steel bar has a large friction force to ensure that the raft steel bar 13 will not slide during the prying process, wherein the horizontal section 4 is used to contact the bottom of the raft steel bar 13 and lift the raft steel bar 13.
[0027] like Figure 1 , 2 As shown, the steel bar 1 is arranged along the center line of the front surface of the flat steel 2, and the top of the steel bar 1 extends out of the top of the flat steel 2 to form a handle 9.
[0028] like Figure 1 , 5 As shown, the prying angle control mechanism includes a fixing plate 6 welded horizontally to the rear end of the flat steel 2, a slanted plate 7 is welded to the rear end of the lower surface of the fixing plate 6, and a lifting lug 16 is provided on the lower surface of the fixing plate 6 inside the slanted plate 7, and the lifting lug 16 is connected to the indicator plate 8 through a connecting ring 15. Figure 4As shown, in the process of prying the raft slab steel bars 13, using too much force is also a reason for damage to the waterproof layer. The present invention can effectively control this problem by setting a prying angle control mechanism. When prying, if the indicator plate fits the inclined surface of the inclined plate, it means that the effective prying angle is reached. At this time, the pad can be placed under the raft slab steel bars, and there is no need to pry too high, thereby further avoiding damage to the waterproof layer.
[0029] like Figure 4 , 5 As shown, the inclination angle of the inclined surface of the inclined plate 7 satisfies that: when the indicator plate 8 is in contact with the inclined surface, the horizontal section 4 pries up the raft slab reinforcement 13 of the construction site to a set height where the concrete pad can be placed. This set height needs to meet the requirement of convenient placement of the concrete pad on the one hand, and avoid prying the raft slab reinforcement too high to damage the waterproof layer on the other hand. The specific data of the set height can be obtained based on construction experience.
[0030] like Figure 4 As shown, when using, insert the bottom of the tool under the raft slab steel bars so that the horizontal section supports the raft slab steel bars, pull the handle backwards, and stop when the indicator plate fits the inclined surface. Then put a concrete pad under the raft slab steel bars and take out the tool after placing it.
