Description

Wall cast-in-place area formwork reinforcing structure and construction method

Technical Field

The invention relates to a wall construction formwork reinforcing technology, in particular to a wall cast-in-place area formwork reinforcing structure and a wall cast-in-place area formwork reinforcing method.

Background

When the prefabricated wall bodies are assembled and constructed, two wall bodies need to be butted, a certain interval is still formed between the two wall bodies after the two wall bodies are butted, and the interval is a cast-in-place area of the wall bodies. The vertical surface of the cast-in-place area is usually open, a template needs to be erected, the template is fixed with the prefabricated wall bodies on two sides, the cast-in-place area is closed, and then concrete is poured into the cast-in-place area from the top, so that the connection of the adjacent prefabricated wall bodies is realized.

At present, the fixing mode of the template mainly comprises two modes. The other is that the internal thread is pre-embedded in the inner wall of the prefabricated wall body to be used as a fixed connection structure with a template and is used for screwing in a screw rod. And the other method is that through holes are arranged in the prefabricated wall body, and the template and the wall body are fixed through split bolts. The disadvantages of using pre-embedded internal threads include: 1. foreign matters, concrete and the like are easy to enter, and the foreign matters enter to cause untightening and damage of the reinforcing expansion die; 2. if the inner wire inclines during pre-embedding, the screw rod is difficult to screw in due to the angle problem during installation. 3. The lead screw is sleeved with a PVC pipe during installation, the PVC pipe protects the lead screw and the concrete during dusting, the PVC pipe is left in the concrete during removal to remove the lead screw, and the lead screw can only be cut if the PVC pipe cannot be removed all the time when entering the ash; 4. and adding a cement cushion block when the formwork is erected. And the problem of using through holes is that: 1. plugging is needed in the later period, and water is easy to enter due to the fact that plugging is not tight; 2. the facing cannot be installed.

Detailed Description

The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments shown in the drawings. It should be understood that these embodiments are described only to enable those skilled in the art to better understand and to implement the present invention, and are not intended to limit the scope of the present invention in any way.

The embodiment of the invention provides a reinforcing structure of a wall cast-in-place area template. In the following embodiments, cast-in-place areas of walls at corners are taken as examples for illustration. The wall body can be a pcf board, a shear wall or a steel structure external hanging board. The pcf board only has outer leaf walls and an insulating layer. The shear wall comprises an outer leaf wall, an insulating layer and an inner leaf wall.

Referring to fig. 1, 6 and 12, a wall cast-in-place area formwork reinforcing structure provided by an embodiment of the invention includes a wall structure 1, a formwork 2 and a first reinforcing fixture 3, wherein the wall structure includes two adjacent walls and a cast-in-place area 101 formed at a joint of the two walls or on an inner side of the walls. Taking the corner connecting structure of the pcf board and the shear wall as an example, the transition area of the shear wall 102 and the pcf board 103 is a cast-in-place area, the inner side of the pcf board is also a cast-in-place area, and the cast-in-place area on the inner side of the pcf board is used for forming the inner leaf wall. Therefore, the cast-in-place area in the embodiment of the invention can be a cast-in-place area in a narrow sense generated when adjacent wall bodies are spliced, and can also comprise a cast-in-place area in a broad sense used for pouring the inner leaf wall.

The formwork 2 is connected to the wall structure 1 to enclose the facade of the cast-in-place area 101. The material of the template 2 can be metal, wood or other materials. When the metal formwork is adopted, the strength is higher, and the stability is higher, so that the fixing points of the formwork and the wall structure can be only arranged on the side edges of the formwork.

First reinforcement frock 3 is used for template 2 and wall structure 1 to consolidate and connects, and first reinforcement frock 3 includes interior screw 301 and fast silk subassembly, and interior screw 301 is located wall structure, and when being located the interior leaf wall, interior screw 301 is called pre-buried interior wall screw, can use MK1 to refer to for short, when being located the outer leaf board, interior screw 301 is called pre-buried outer leaf board screw, for short MK 2. The quick wire component is connected with one end of the inner nut 301 close to the formwork 2, so that the formwork and the wall structure are fixed. As shown in fig. 14, the inner nut 301 has a hollow structure therein, and has a protrusion 3011 on the inner side of at least one end of the hollow structure for connection with a fast wire assembly. The inner nut 301 is a bar shape as a whole, has a hollow structure inside, and has a protrusion 3011 on the inner side of the end. For example, when the inner nut is made of metal, the inner nut 301 may be formed with a plurality of recesses by striking on the outer surface thereof, and the protrusions 3011 may be formed on the inner side of the inner nut. Meanwhile, the protrusion 3011 is relatively thick compared with the thread of the inner wire, and the accuracy of the shape is relatively low, so when the outer wire of the fast wire assembly is connected, the requirement on the connection accuracy is not high, and even if a little dust enters the hollow structure, the effective connection is not affected, so the fault tolerance rate is higher during connection. The threads in the inner thread are very precise, and if dust enters a little, the threads are filled and leveled, and connection cannot be realized.

The inner screw 301 may be located at a plurality of positions according to the wall structure and the corner structure, for example, may be located in an inner leaf wall, an outer leaf wall and a heat insulation board, and a cast-in-place area.

When the cast-in-place area is a corner cast-in-place area, a second reinforcing tool 4 is arranged in the corner cast-in-place area; the second reinforcing tool 4 comprises a second embedded part 402, a heat-insulating drawknot member 403 and a connecting part 401 for connecting the second embedded part 402 and the heat-insulating drawknot member 403; the second embedded member 402 is located in the

inner leaf walls

102a, 103a over the corners, and the ends of the insulation tie 403 extend from the insulation layers 102b, 103 b. The second reinforcing tool 4 is used for pulling the outer blade plates and the heat insulation layers of the corners to prevent the outer blade plates and the heat insulation layers from expanding and moving outwards when concrete is poured. In the cross wall, the second reinforcement tool 4 is also arranged in a cross manner.

As shown in fig. 4, the connecting member 401 is connected to the end of the second embedded member 402 and the end of the thermal insulation pulling member 403 by a hook structure. The mode of pothook connection is quick and convenient, has improved the efficiency of construction. For example, second embedded member 402 may be a rebar with a circular ring at the end of the rebar. As shown in fig. 15-17, the ends of the heat-insulating tie member 403 may be U-shaped members or V-shaped members (i.e., the ends are bent back in an arc shape or in a pointed shape), two reinforcing bars extending from the closed ends of the U-shaped members and the V-shaped members sequentially penetrate into the heat-insulating

layers

102b and 103b and the

outer leaf walls

102c and 103c, and the portions of the

outer leaf walls

Both ends of the connecting piece 401 are hooks for connecting the end of the heat-insulating drawknot 403 and the end of the second embedded piece 403 respectively. Further, the heat insulating tie 403 may be as shown in fig. 5.

In other embodiments, as shown in fig. 18, the end of the thermal insulation tie 403 is V-shaped, so that the end of the thermal insulation tie 403 and the second adjusting screw 4012 are more consistent in size and are not easily deformed when the wall structure is tied.
