[0002] At present, there are two main methods of concrete modular production in the industry. One is the form of casting the whole mold, and the other is the form of prefabricating part of the concrete and casting part (connecting nodes) with a supporting formwork. For complex modules, the higher the degree of prefabrication, the higher the efficiency of the module production; in the form of prefabricated assembly, the various components are assembled and finally cast into shape. The efficiency of the whole process and the control of assembly quality (module verticality, squareness, assembly error) are the key. Assembly tools are the key factors affecting assembly efficiency. Traditional module installation uses inclined supports for wall fixing + floor buckle frames, but the buckle frames are relatively scattered, time-consuming and labor-intensive to install and disassemble, and have low precision, which belongs to traditional processes; secondly, the whole inner mold + outer frame is adopted, but this method has a heavier mold, a large amount of steel, and a higher cost, and it is not convenient to disassemble and fix components.

[0034] This embodiment provides a quick assembly tooling frame for prefabricated concrete modules. Figure 1 The assembly tool frame includes a mold platform 1, a slide rail 2, a frame body 3, a wall adjustment device 4, a tool positioner 5, a joint template 6 and a corner angle steel template 7.

[0035] A plurality of slide rails 2 are fixed on the mold platform 1 at intervals, and their length direction is parallel to the width direction of the mold platform 1. Figure 2 The bottom of the frame 3 is provided with a pulley 8, which is located on the top surface of the slide rail 2. The frame 3 can slide back and forth along the length direction of the slide rail 2 (i.e., slide along the inside and outside direction of the mold platform 1). The verticality of the slide rail 2 and the mold platform 1 is used as the verticality reference for component installation.

[0036] The frame 3 includes a wall tool frame 31, a floor support bracket 32 ​​and a corner tool frame 33. Specifically, two sets of frames 3 arranged opposite to each other are provided on the mold platform 1, and the floor support bracket 32 ​​is installed on the top of the wall tool frame 31.

[0037] The floor support bracket 32 ​​includes a hollow support pole 321, a flat tube 322 and a support 323. The quick assembly tool frame of this embodiment also includes a floor support bracket adjustment device, which includes a mother sleeve 324, a sub-sleeve 325 with threaded teeth, a support screw 326 and a nut 327. The support pole 321 is fixed on the wall tool frame 31, the nut 327 is fixed on the top of the support pole 321, the support screw 326 is inserted into the support pole 321, and its top end is threadedly connected with the nut 327, and the sub-sleeve 325 is fixed on the top of the support screw 326; the mother sleeve 324 is fixed under the support 323, the sub-sleeve 325 is inserted into the mother sleeve 324 and threadedly connected with the mother sleeve 324; the flat tube 322 is set horizontally to ensure the flatness of the floor installation. The support 323 is a U-shaped support, and the support 323 is used to support the flat tube 322. By screwing the support screw 326, the flat channel 322 can be raised or lowered to adapt to the floor slabs of modules with different floor heights.

[0038] The support screw 326 is located at the lower side of the tooling frame, close to the mold table at a certain height. This height ensures that the operator can operate on the mold table and rotate the support screw 326 to the designed height. The height adjustment of the support screw 326 can be achieved on the ground without climbing. A scale is installed in the adjustment area of ​​the support screw 326 to observe the top elevation of the support screw 326 in real time to determine whether the support screw 326 is adjusted in place.

[0039] A plurality of wall adjustment devices 4 are fixed at the edge of the mold platform 1 at intervals in the circumferential direction. Figure 3 The wall adjustment device 4 includes a first fixing nut 41, a first adjusting screw 42 and a first movable gasket 43; the first fixing nut 41 is fixed on the mold platform 1, the first adjusting screw 42 is inserted into the first fixing nut 41 and is threadedly connected with the first fixing nut 41, and the first movable gasket 43 is located at the tail end of the first adjusting screw 42; when installing the component, the position of the component can be adjusted through the first adjusting screw 42.

[0040] In order to ensure the verticality of the corner position of the module, a corner fixture frame 33 is designed. The corner fixture frame 33 is rotatably installed on both sides of the wall fixture frame 31 through hinges a. Before the module is assembled, the hinge a is fixed by the support rod b. When demoulding, the support rod b is removed and the hinge a is tightened to ensure that the corner fixture frame 33 does not contact the component and that the corner fixture frame 33 can be retracted synchronously with the overall fixture.

[0041] The two opposite outer sides of the bottom of the frame are respectively fixed with tooling locators 5, and the fixed legs of the tooling locators 5 are in close contact with the crossbar of the frame 3 and locked with screws to prevent the tooling frame from overturning, thereby ensuring the relative flatness and verticality of the inner wall of the module and the high-precision flatness and verticality of the tooling frame itself.

[0042] The joint template 6 is vertically fixed on the mold platform 1 and is located at the outer side of the frame. In this embodiment, the joint template 6 adopts a shaped steel template, and the joint template 6 is made in an integrated manner with the tooling frame, and the joint template 6 is retracted in an integrated manner when the mold is removed.

[0043] The corner angle steel template 7 is located at the corner position of the corner fixture frame 33. In this embodiment, the corner angle steel template 7 is made of angle steel profile, and the angle steel is tightened by bolt sleeves to serve as a mold for small-sized joints at the corner position.

[0044] Further, refer to Figure 4 The assembly tooling frame of this embodiment also includes an angle steel template adjustment device, which includes a second fixing nut 81 and a second adjusting screw 82. The second fixing nut 81 is fixed on the corner tooling frame 33. The second adjusting screw 82 is inserted into the second fixing nut 81 and is threadedly connected with the second fixing nut 81. The tail end of the second adjusting screw 81 abuts against the inner corner of the corner angle steel template 7.

[0045] Two square tubes 311 arranged at intervals in the upper and lower sides are fixed on the outer side of the wall fixture frame 31, and the inner side of the two square tubes 311 is installed with a wall fixing device 312, which includes a second movable gasket 3121 and a high-strength bolt 3122. The second movable gasket 3121 is located on the inner side of the square tube, and its height is greater than the spacing between the two square tubes 311. The high-strength bolt 3122 passes through the second movable gasket 3121 and is threadedly connected with the bolt sleeve pre-embedded in the wall. By designing a through hole 313 in a double-pass form on the inner side of the module, the through hole 313 has a certain spatial hole position, which serves as a temporary fixing point for the wall component. The through hole 313 can be arbitrarily adjusted in the length direction, and the height direction is embedded in the bolt sleeve according to the position of the fixture frame when designing the prefabricated component. This method has low requirements on the accuracy of the embedded bolt position, and can realize the rapid fixing and assembly and disassembly of the wall component. At the same time, when there are door and window openings in the wall, it is not restricted by the openings.
