Description

Auxiliary tool for building carrier plate sleeve construction Technical Field The utility model relates to the field of construction of building carrier plates of dismantling-free steel bar trusses, in particular to an auxiliary tool for construction of a sleeve of a building carrier plate. Background At present, no special auxiliary embedding fixing device tool and method are needed when the sleeve is embedded on the floor support plate, and the embedding methods of the sleeves made of different materials are different. The first steel sleeve is characterized in that a sleeve positioning hole is formed in a galvanized iron plate at the bottom of a floor support plate, an outer ear is welded to the lower end of the steel sleeve (a screw hole is formed), sleeve pre-embedding nailing fixation is performed by adopting a self-tapping screw according to the hole forming position, and the other method is that after the galvanized iron plate is used for positioning the sleeve, the sleeve and the galvanized plate are directly subjected to spot welding fixation. The second type of PVC sleeve currently adopts a binding wire matched iron nail nailing and fixing mode. The problems of the prior art include that (1) the plate surface is perforated in advance to reduce the plate surface strength of a galvanized iron plate at a hole position and increase the vertical disturbance, the plate body is deformed to cause the deviation of the sleeve when the sleeve is installed according to the prior embedding method, (2) the control difficulty of the size precision of the perforated plate is larger when the plate surface is perforated, the size of the perforated plate is smaller than the inner diameter of the sleeve, no special perforation tool is needed, the perforation is too large to cause the leakage of the sleeve and the galvanized plate at the joint position, the perforation is too small to cause secondary perforation, 3) the sleeve is fixed by adopting an external ear and a tapping screw, the stability is insufficient, the sleeve inclination problem occurs, and (4) the steel sleeve and the galvanized plate are welded to cause the rust at the welding spot position, meanwhile, the sleeve is small in thickness, the welding is not firm enough, the welding risk exists, the concrete pouring leakage problem is caused, and the like, meanwhile, the sleeve is a cantilever member, the axis deviation exists, the forming quality and the use function is influenced, and the prior wire binding iron nail is pressed for the PVC sleeve, the precision is low, the sleeve and the integral sleeve and the overall construction quality and the concrete truss leakage quality are influenced. The non-standardization auxiliary pre-buried fixing device and the method are reserved for the plate penetrating sleeve on the floor support plate at a time. Considering that when the sleeve pipe of the traditional building carrier plate is pre-buried, modes such as outer ear adding self-tapping screw, welding and binding screw pressing are adopted, the stability is poor, the sleeve pipe shift and eccentric incidence rate is high, meanwhile, the slurry leakage condition at the tapping interface is common, the pre-buried precision of the sleeve pipe is finally reduced, the corrosion and water leakage at the welding point are finally caused, the forming quality is poor, even the deviation cannot be used, and the overall forming quality and the construction cost control of the steel bar truss concrete floor slab are adversely affected. Therefore, in order to solve the above problems, an auxiliary tool for construction of the sleeve of the floor support plate is needed, the common quality problems of deviation, inclination, slurry leakage at joints and the like of the sleeve in the concrete pouring process and construction operation can be solved, the problem that the sleeve is reduced in use function, reworking and repair are caused, the cost of materials and labor is increased, the integral forming quality of the reinforced truss concrete floor is affected, and the defect that an auxiliary pre-buried fixing device cannot be recycled is overcome. Disclosure of utility model In view of the above, the utility model aims to overcome the defects in the prior art, provide an auxiliary tool for construction of the sleeve of the floor support plate, solve the problems that the sleeve has deviation, inclination, slurry leakage at joints and the like in the concrete pouring process and construction operation, reduce the use function of the sleeve, cause reworking and repair, increase the cost of materials and labor, influence the integral forming quality of the reinforced truss concrete floor and overcome the defect that an auxiliary pre-buried fixing device cannot be recycled. The utility model relates to an auxiliary tool for building carrier plate sleeve construction, which comprises a sleeve positioning assembly, wherein the sleeve positioning assembly comprises a posit
