Description

Technical Field

[0001] The invention relates to a manufacturing device for an outer leaf wall piece of a sandwich thermal insulation wall and a construction method thereof, belonging to the technical field of component manufacturing devices. Background Art

[0002] The country vigorously advocates the industrialization of new buildings, among which the assembly construction of components is a key development technology, which is currently developing at an unprecedented speed. In the field of masonry structures, assembly technology is also developing rapidly. There are already mature construction processes and tools and equipment for the assembly construction of load-bearing structural components. However, in terms of enclosure structures, especially the outer leaf walls and partition walls of sandwich walls with smaller thickness, they are difficult to manufacture because they do not have the ability to stand on their own, which is not conducive to factory production and assembly installation.

[0003] Most of these thin wall pieces are hollow wall pieces. They are widely used not only in the field of masonry structures, but also in buildings of other structural forms, such as partition walls of steel-structured houses and concrete-structured houses. The current practice is to use in-situ masonry, that is, to build wall pieces one by one on site. This is a traditional practice. Judging from the current value system, it is not conducive to environmental protection, the amount of wet work on site is large, and a lot of construction waste is generated. It is a construction method that is gradually being replaced.

[0004] However, this kind of wall piece itself has good applicability and good performance, and its cost is low. It would be a pity if it is eliminated in the tide of assembly. When it is used as an outer leaf wall, combined with prestressed technology, the inner and outer leaf wall tie bars in the sandwich wall can be eliminated, which is very in line with the needs of energy saving. If its production can be freed from the limitation of in-situ masonry, it will be a blessing for this kind of excellent performance component.

[0005] At present, there are some practices in foreign countries to implement assembly construction for thinner wall pieces. The main objects are hollow brick wall pieces. The horizontal mortar joints are full during masonry, and the thickness is generally about 120mm. Such wall pieces have a certain degree of self-sustainability. In addition, they are made in factories with good production conditions. After the masonry is completed, they are packaged and installed on site. As for 90mm thick hollow block wall pieces, there are no relevant technical reports. There is no assembly construction of hollow block wall pieces with a thickness of less than 90mm in this field at home and abroad.

[0006] At present, 90mm thick hollow block walls are generally used in two directions: one is as the outer leaf wall of the sandwich wall; the other is as an ordinary indoor partition wall. The current practice is to build in situ, such as the outer leaf wall of the sandwich wall, which is tied to the inner leaf wall with tie bars while being built, and the inner leaf wall provides its lateral constraints to maintain its own stability. Partition walls are generally short in length and have turns, which are equivalent to spatial components. They are not completely straight walls, so their overall stability can be guaranteed. Summary of the invention

[0007] The present invention is to realize the assembled construction of the outer leaf wall of the sandwich wall and the assembled construction of the thinner inner partition wall, so that the thinner wall pieces can overcome the lack of self-supporting ability. A sandwich insulation wall outer leaf wall piece production system and a construction method are proposed, in particular, a thinner block wall piece production device, which can also be used for the production of ordinary thin wall pieces that cannot be self-supporting.

The temporary limiting device for building blocks is fixed on the sub-frame after the wall pieces are laid to limit the position of each building block. After the mortar on the back of the wall pieces is filled and the system is reset, the temporary limiting device for building blocks is removed from the sub-frame.

DETAILED DESCRIPTION

[0044] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings:

[0045] Specific implementation method 1: See Figure 1-9 The present embodiment is described. The device for making the outer leaf wall of the sandwich insulation wall described in the present embodiment comprises a sub-frame 1, a flipping system 2 and a temporary block limiting device. The flipping system 2 is installed on the back of the sub-frame 1. During masonry, the sub-frame 1 is placed together. The sub-frame 1 comprises a sub-frame and a main frame. The sub-frame supports the blocks. The sub-frame is placed on the main frame. The main frame provides support for the sub-frame and also provides a limit for the blocks to ensure the size and level of the mortar joints of the blocks. The temporary block limiting device is fixed on the sub-frame after the wall pieces are laid to limit the position of each block. After the mortar on the back of the wall pieces is filled and the system is reset, it is removed from the sub-frame.

[0046] The sub-frame includes a sub-frame top beam 3, 4 hanging points 4, a plurality of sub-frame small steel beams 5, a notch 6 and a sub-frame bottom beam 7. A plurality of sub-frame small steel beams 5 are vertically arranged between the sub-frame top beam 3 and the sub-frame bottom beam 7. Two hanging points 4 are arranged at both ends of the sub-frame top beam 3 and the sub-frame bottom beam 7. A notch 6 is arranged at the connection between each sub-frame small steel beam 5 and the sub-frame bottom beam 7.

[0047] The mother frame includes a mother frame top beam 8, a mother frame support beam 10, a plurality of block positioning beams 11, a gap 12, a mother frame bottom beam 13 and a mother frame locking device 22. A plurality of block positioning beams 11 are vertically installed between the mother frame top beam 8 and the mother frame bottom beam 13. A gap 12 is provided at the connection between the block positioning beam 11 and the mother frame bottom beam 13. A mother frame support beam 10 is installed on the back of the block positioning beam 11. The mother frame top beam 8 and the mother frame bottom beam 13 are both provided with a mother frame locking device 22. A plurality of block limiting strips 9 are provided on the block positioning beam 11.

[0048] The temporary limiting device for the building blocks includes two cross beams 18, a plurality of locking devices 19, a small steel beam 20 and a spring limiting device 21. A plurality of small steel beams 20 are vertically installed between the two cross beams 18. A plurality of locking devices 19 are installed on the two cross beams 18. The locking devices 19 correspond to the mother frame locking devices 22 on the mother frame to complete the fixation of the temporary limiting device for the building blocks and the mother frame.

[0049] The spring limiting device 21 includes a rubber pad 14, a steel rod 15, a spring 16 and a steel sleeve 17. The bottom of the steel sleeve 17 is provided with a spring 16, and the steel rod 15 and the rubber pad 14 are sequentially mounted on the spring 16.

[0050] The distance between two adjacent spring limiters 21 is the width of a building block. The spring limiter 21 is located at the center of the building block to position the building block.

[0051] (1) Sub-rack. The sub-rack consists of Figure 2 As shown, the small steel beam 5 is used to place the blocks, the top beam 3 and the bottom beam 7 are needed to form the framework, and are also used as force transmission components during hoisting. At the bottom of the wall piece, a gap 6 is left to allow the angle steel at the bottom of the wall piece to pass through.

[0052] The sub-frame is placed on the mother frame. By reasonably setting the form of the mother frame, the two are almost in the same plane. The sub-frame supports the blocks, and the block limiting devices of the mother frame protrude from the plane of the sub-frame, so that the blocks can be placed on these devices to maintain a fixed distance between each layer of blocks.

[0053] (2) Mother frame. The mother frame consists of Figure 4 The block limit strip 9 is welded to the positioning beam 11 of the mother frame, and together with the top beam 8 and the bottom beam 13, forms the mother frame as a whole. The mother frame support beam 10 is used to connect with the oil cylinder jack of the turning system 2, so as to realize the rotation of the entire masonry support system by the turning system 2, so as to fill the mortar joints.

[0054] (3) Assemble the sub-frame and the mother frame. Figure 5 As shown, the sub-frame (together with the wall pieces on it) can be lifted away separately, and the new sub-frame can be placed on the mother frame to continue the masonry work. The sub-frame can be recycled again after the wall pieces are tied and removed.

[0055] (4) Temporary block limiting device. This system solves the problem of blocks not moving when the wall is turned over. As shown in the figure, its size is the same as the mother-and-child frame. A spring limiting device 21 is set on each small steel beam 20. A certain force is applied to the spring limiting device 21, which presses the block against the mother-and-child frame. It is used to limit the position of the block hanging on the mother-and-child frame when the wall is upright so that it does not move. After filling the horizontal mortar joints on the back of the wall, the wall is restored to its initial tilted position and the temporary binding system is removed.

[0056] (5) Figure 8 After the wall pieces are laid out and the front mortar is filled, the blocks are fixed on the sub-frame using temporary block limiting devices. At this time, the wall pieces can be turned over to fill the mortar on the back of the wall pieces.

[0057] The construction method using the sandwich insulation wall outer leaf wall production device is:

[0058] (1) The entire device is placed at 40-50 degrees to the ground. The rotation of the masonry system is driven by a hydraulic cylinder, and the sub-frame and the main frame are placed together;

[0059] (2) Place the blocks one by one on the rack according to the block wall design drawing, and lay the vertical mortar joints of the blocks at the same time;

[0060] (3) After each layer of blocks is laid, the mortar limit strip 23 is clamped at the horizontal mortar joint using the limit device 24;

[0061] (4) After all the blocks are placed, use a mortar extrusion device to fill the horizontal mortar joints on the front with mortar;

[0062] (5) Use temporary lashing devices to secure the block wall to the subframe;

[0063] (6) Turn the frame over so that the back is basically vertical, and then fill the horizontal joints with mortar;

[0064] (7) After all horizontal joints are filled, reset the mother-child frame 1;

[0065] (8) Use a hook to lift the sub-frame together with the wall piece to the curing place for curing, and remove the temporary binding device;

[0066] (9) When the wall mortar reaches the predetermined strength, prestress can be applied to make the wall ready for lifting.

[0067] The present invention is a system, which includes physical components such as a sub-frame, a mother frame, a turning system, and a binding device. The entire system realizes the masonry operation of thinner hollow wall pieces, avoiding the problem that the one-line hollow block wall piece cannot be manufactured due to insufficient self-support. In addition, the present invention provides a method of not applying full horizontal mortar joints but only applying mortar on the block wall and ribs.

[0068] Features of this production device:

[0069] 1. Working in the form of a mother-and-child frame, the mother-and-child frames work together to form a working surface when making (building) wall pieces. When the wall pieces are made, the sub-frame and the wall pieces are hoisted away from the system and the mother frame to a static area for curing.

[0070] 2. The device provides a positioning device for each building block, and the building blocks are placed in place to form the entire wall.

[0071] 3. The mortar is filled afterward.

[0072] 4. The system can be turned over and kept at a certain inclination during masonry. After filling the mortar joints on one side, temporarily fix the wall blocks, turn the entire system over, and fill the mortar joints on the other side.

[0073] 5. The vertical mortar joints between blocks can be set during the laying of masonry blocks to reduce the amount of mortar filling work.
