Description

Technical Field

[0001] The utility model relates to the technical field of construction auxiliary devices, in particular to a reinforcing and compacting device for a composite plate. Background Art

[0002] In the construction of conventional composite floor slabs, there is more or less a gap between the formwork and the composite slab due to errors in the installation of the formwork and the construction of the composite slab. After the pouring of the slab, the concrete slurry flowing in through the gap will seriously affect the appearance and quality of the slab. After the construction of conventional composite floor slabs is completed, there is leakage under most of the composite slabs, and the slurry is not tightly combined with the composite slab. If not handled properly, quality problems such as cracks, warping and falling off are very likely to occur in the later interior decoration.

[0003] In addition, there are gaps between the composite slabs. The gaps between the composite slabs and the connections with the cast-in-place concrete are the vertical joints between the new and old concrete, which are the weak strength areas of the floor structure. At present, there are generally only small-diameter anchor lap bars between the composite slabs. The connections between the composite slabs have high requirements for construction joint treatment such as chiseling and cleaning of the edges of the composite slabs and vibration of the cast-in-place concrete. When the construction quality does not fully meet the specifications, quality risks are prone to occur.

[0004] To address the above issues, the current common solution is to stick foam tape around the edge of the composite board after the installation is completed. This can reduce leakage to a certain extent, but it cannot completely eliminate it. As for the problem of weak strength, there is currently no better technical solution.

[0005] Based on this, the inventor has designed a reinforcement and compression device for composite plates to solve one or more of the above-mentioned problems, and thus proposed the present application. Utility Model Content

DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below in conjunction with the embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model.

[0029] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "open", "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] like Figures 1 to 3 As shown, this embodiment provides a reinforcing and pressing device for a laminated plate, comprising a reinforcing and pressing rod 1 for being placed on two laminated plate bodies 5, and a screw assembly 2 which is perpendicular to and fixedly connected to the reinforcing and pressing rod 1;

[0032] It also includes a locking and pressing component 3 for driving the reinforcing and pressing rod 1 to squeeze the overlapping plate body 5 close to the template 7, and the locking and pressing component 3 is sleeved on the screw rod component 2.

[0033] Compared with the prior art in which the composite board is placed on the template 7 by its own weight, the present application can use the reinforcing compaction rod 1 to press down the composite board body 5, thereby reducing or even eliminating the gap between the composite board body 5 and the template 7, and preventing the slurry from flowing under the composite board body 5, which will cause quality problems such as cracks, warping and falling off in the later interior decoration after the slurry solidifies.

[0034] In addition, since the reinforcing compression rod 1 is placed between the two superimposed plates 5, it can also improve the structural strength of the weak points between the reinforced superimposed plates 5, thereby solving the problem of weak structural strength areas between the superimposed plates in the prior art.

[0035] Therefore, the core concept of the present application is to use a reinforcing compression rod 1 to simultaneously press two composite panels 5, which can not only squeeze the composite panels 5 to achieve compression between the composite panels 5 and the formwork 7, but also solve the problem of weak structural strength areas between the composite panels 5 after concrete pouring.

[0036] In this embodiment, the screw assembly 2 includes a first screw 21 and a second screw 22 coaxially arranged, and a connecting sleeve 23 for connecting the first screw 21 and the second screw 22. The first screw 21 is vertically fixedly connected to the middle position of the reinforcing and compacting rod 1, and the first screw 21 and the second screw 22 are both detachably connected to the connecting sleeve 23. By providing the first screw 21 and the second screw 22, and the connecting sleeve 23, the connecting sleeve 23 and the second screw 22 can be removed after the poured concrete solidifies, which can reduce the cost of building materials and facilitate disassembly.

[0037] In this embodiment, if Figure 1 As shown, an elastic plug 4 for preventing grout leakage is also included, and the elastic plug 4 is sleeved on the connecting sleeve 23, and the top of the elastic plug 4 extends out of the connecting sleeve 23. By providing the elastic plug 4, when the connecting sleeve 23 and the second screw 22 are disassembled, the elastic plug 4 can be squeezed by hand or an auxiliary tool to deform it, so that the elastic plug 4 is separated from the contact surface of the solidified concrete, thereby facilitating the disassembly of the connecting sleeve 23.

[0038] In this embodiment, if Figure 1As shown, the elastic plug 4 is in a conical shape, and the top of the conical elastic plug 4 is arranged close to the first screw 21 , and the bottom is arranged close to the second screw 22 .

[0039] Specifically, the elastic plug 4 is in a conical shape, and the height between the top and bottom of the elastic plug 4 is greater than the thickness of the template 7;

[0040] The elastic plug 4 is made of rubber or silicone. In this embodiment, the elastic plug 4 is made of rubber. The height between the top and bottom of the elastic plug 4 is greater than the thickness of the template 7, which is more convenient for operators to remove.

[0041] like Figure 1 and Figure 3 As shown, the locking assembly 3 includes a concave member 31 for accommodating and pressing the back-corrugated steel pipe 9, and a locking nut 32 threadedly connected to the second screw 22. The concave member 31 is sleeved on the second screw 22, and the concave member 31 is located between the connecting sleeve 23 and the locking nut 32, and the concave side of the concave member 31 is arranged toward the connecting sleeve 23. The concave member 31 can place the back-corrugated steel pipe 9 between the concave members 31, and when the composite plate body 5 is driven close to the template 7, the back-corrugated steel pipe 9 is prevented from falling off.

[0042] Specifically, the locking nut 32 is a mountain-shaped nut. The mountain-shaped nut is convenient to tighten, so that the mountain-shaped nut squeezes the concave member 31 to squeeze the back corrugated steel pipe 9, so that the back corrugated steel pipe 9 squeezes the wooden beam 8 and the template 7, thereby squeezing the template 7 and the laminated board on both sides of the template 7 and the laminated board body 5, so that the gap between the template 7 and the laminated board body 5 is removed, and the cement slurry is prevented from flowing into the gap between the template 7 and the laminated board body 5 when pouring concrete.

[0043] In some preferred embodiments, the first screw 21 and the second screw 22 have the same diameter, and the diameter range is 5 mm-20 mm.

[0044] In this embodiment, the diameters of the first screw rod 21 and the second screw rod 22 are 10 mm, and one end of the first screw rod 21 away from the second screw rod 22 is welded and fixed to the reinforcing and pressing rod 1 .

[0045] In some preferred embodiments, the reinforcing and compacting rod 1 is made of steel bars with a diameter greater than or equal to 20 mm, and the length of the reinforcing and compacting rod 1 is greater than or equal to 200 mm. In this embodiment, the length of the reinforcing and compacting rod 1 is greater than 400 mm, and the overlap distance between each laminated plate 5 and the reinforcing and compacting rod 1 is greater than 200 mm, ensuring the regional structural strength between the laminated plates 5 after pouring concrete.

[0046] When this embodiment is used in construction, first, after the installation of the composite plate is completed, a hole is drilled at the corresponding position in the gap of the composite plate, and then the screw assembly 2 and the rubber plug are placed into the hole of the template 7, and the position of the reinforcing and compacting rod 1 is adjusted so that the rod body fits well with the left and right composite plates. After the back corrugated steel pipe 9 under the bottom template 7 is adjusted, the concave component is inserted into the second screw 22 so that the concave component fits well with the back corrugated steel pipe 9, and the mountain nut is inserted and tightened. At this time, the composite plate fits tightly with the template 7, and the paddle body will not enter between the composite plate and the template 7. Then, the upper layer of the floor steel bar is laid according to the requirements of the design drawings. After the upper layer of the steel bar is laid and accepted, the floor concrete is poured and maintained according to the standard procedures. After the concrete meets the requirements for demolding, the mountain nut, the concave component 31, the second screw 22 and the connecting sleeve 23, the back corrugated steel pipe 9, the wooden beam 8, the template 7 and the rubber plug are removed in sequence. After the demolition is completed, the original rubber plug area is filled and leveled with cement mortar. At this point, the entire construction process is completed.

[0047] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
