Technical field
The invention belongs to construction engineering technical field, relate to a kind of plain type NZ built-in pipe die anti-floating hook structure and construction installation method thereof.
Background technology
The built-in pipe die anti-floating of the NZ drag hook using in building operations mostly at present is and in floor, between NZ pipe die gap, adopts reinforcing bar drag hook and the colligation of anti-floating beading galvanized wire fastening, so that reinforcing bar drag hook tension pipe die prevents pipe die whole floating in concreting process.Lifting hook device and the installation thereof of this structure exist constructional difficulties, and tighten not can cause the unbalanced and problems such as distortion of part extruding to pipe die in to pipe die tension and compression.
Summary of the invention
The object of the invention is the deficiency existing in order to solve above-mentioned prior art, provide a kind of simple in structure, drawknot stable, can effectively control the integral body floating of pipe die in concreting process, easy construction and safety and the built-in pipe die anti-floating of the reusable plain type NZ of part lifting hook device.The present invention also provides the construction method of this device.
Object of the present invention is achieved through the following technical solutions.
The built-in pipe die anti-floating of plain type NZ lifting hook device, this device includes pull bar, sizing reinforcing bar card, mountain type card and hold-doun nut thereof; Described pull bar includes the upright steel bar rod section of top band crotch and is with externally threaded upright reinforcing bar wire drawing section, and pull bar pars infrasegmentalis and wire drawing section top overlap integrally welded mutually; Described sizing reinforcing bar card comprises the transverse reinforcement of level and is welded in the longitudinal reinforcement of two levels at transverse reinforcement middle part, and two longitudinal reinforcements are parallel to each other and are perpendicular with transverse reinforcement; Sizing reinforcing bar card is installed on the wire drawing section of upright pull bar between the longitudinal reinforcement of two levels, and mountain type cutting ferrule is contained in wire drawing section and is positioned at the bottom of sizing reinforcing bar card, at wire drawing section Yushan Hill type card bottom suit hold-doun nut.
The construction method of the built-in pipe die anti-floating of plain type NZ lifting hook device, method step is as follows:
(a) pull bar is installed: the crotch on reinforcing steel bar of pull rod pull bar section top is drawn steady on the horizontal Anti-floating reinforcing steel bar of the built-in pipe die of plain type NZ, reinforcing bar wire drawing section is vertically through bottom template, and pull bar is in place;
(b) sizing reinforcing bar card is installed: sizing reinforcing bar card level is installed on bottom template to flitch or C shaped steel bottom and flitch or C shaped steel and holds out against, and the wire drawing section of upright pull bar is installed between the longitudinal reinforcement of two levels;
(c) mountain type card is installed: the mountain type card that is set in wire drawing section is risen to the reinforcing bar card of shaping and held out against, the nut that is tightened, mountain type card is firmly fixing.
The built-in pipe die anti-floating of plain type NZ of the present invention lifting hook device is simple in structure, drawknot stable, can effectively control the integral body floating of pipe die in concreting process.Easy and the safety of construction method, and after construction, mountain type card, hold-doun nut and sizing reinforcing bar card can be disassembled and reuse.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the built-in pipe die anti-floating of plain type NZ of the present invention lifting hook device;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in more detail.
As shown in Figure 1 and Figure 2, the built-in pipe die anti-floating of plain type NZ lifting hook device includes pull bar, sizing reinforcing bar card 3, mountain type card 4 and hold-doun nut 5 thereof.Pull bar includes the upright steel bar rod section 1 of top band crotch and is with externally threaded upright reinforcing bar wire drawing section 2, pull bar section 1 bottom and wire drawing section 2 tops overlap integrally welded mutually. and sizing reinforcing bar card 3 comprises the transverse reinforcement 3a of level and is welded in the longitudinal reinforcement 3b of two levels at transverse reinforcement middle part, and two longitudinal reinforcements are parallel to each other and are perpendicular with transverse reinforcement; Sizing reinforcing bar card is installed on the wire drawing section 2 of upright pull bar between the longitudinal reinforcement of two levels, and mountain type card 4 is sleeved in wire drawing section 2 and is positioned at the bottom of sizing reinforcing bar card 3, in wire drawing section 2, is positioned at type card bottom, mountain suit hold-doun nut 5.
The construction method step of the built-in pipe die anti-floating of plain type NZ lifting hook device is as follows:
(a) pull bar is installed: the crotch on reinforcing steel bar of pull rod pull bar section 1 top is drawn steady on the horizontal Anti-floating reinforcing steel bar of the built-in pipe die of plain type NZ, reinforcing bar wire drawing section 2 is vertical through bottom template, and pull bar is in place;
(b) sizing reinforcing bar card is installed: sizing reinforcing bar card 3 levels are installed on bottom template to flitch or C shaped steel bottom and flitch or C shaped steel and hold out against, and the wire drawing section 2 of upright pull bar is installed between the longitudinal reinforcement of two levels;
