Description

Technical Field

[0001] The utility model relates to the technical field of steel template installation, in particular to a novel inner pull type steel template installation structure. Background Art

[0002] Water-stabilized concrete construction is the key and difficult part of pavement engineering. Whether the placement of steel formwork is stable or fast during the paving process is directly related to the project construction quality and progress.

[0003] The construction of water-stable base has the characteristics of long construction mileage, fast construction speed and high flatness requirements. Traditional non-formwork construction, earth formwork and wooden formwork support technology are far from meeting the construction requirements. Therefore, the current common method is to use channel steel + steel chisel; such as the road water-stable base formwork reinforcement system disclosed in patent application number 201620975710.0, which uses the triangular support principle to form a triangular point support on the horizontal back of the channel steel formwork (the two points of the staggered arrangement of the first steel plate mounting holes in the two adjacent groups of reinforcement devices and the flat contact fixing points between the channel steel formworks) to prevent the channel steel formwork from being overturned by external forces; but in the actual construction process, it is time-consuming and labor-intensive. Utility Model Content

[0004] The utility model aims to solve the problems existing in the prior art and proposes a novel inner pull-type steel template installation structure.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A novel inner pull-type steel formwork installation structure comprises a channel steel formwork, a fixed steel wire and a fixed steel nail. One end of the fixed steel wire is provided with two cross bars, and the two cross bars are arranged in parallel, and the other end is hook-shaped. A plurality of through grooves are opened on the side wall of the channel steel formwork, and the size of the through grooves is adapted to the shape and size of the cross bars, and the two cross bars are respectively located on both sides of the side wall of the channel steel formwork. The fixed steel nail passes through the hook-shaped end of the fixed steel wire and is fixed on the water-stable base.

[0007] An insert tube is installed in the middle of one of the cross bars, and an insert rod is installed in the middle of the other cross bar, and a spring is installed at the end of the insert rod. The spring is located in the insert tube, and the other end of the spring is fixedly connected to the inner end of the insert tube. The cross-sections of the end of the insert rod and the inner cavity end of the insert tube are both rectangular, the spacing between the two cross bars is slightly smaller than the thickness of the through groove, and the two cross bars are both cylindrical.

[0008] Preferably, the length of the fixing wire is between 40-50 cm and the diameter is 4 mm.

[0009] Preferably, the number of the through grooves is three, which are respectively located on both sides and the middle of the side walls of the channel steel formwork. The through grooves are rectangular, with a length of 5 cm and a width of 1 cm.

[0010] Preferably, a bolt is movably penetrated and connected to the middle of the crossbar, and the end of the bolt movably penetrates the insertion rod into the insertion tube and is screwed to the inner end of the insertion tube through a threaded hole.

[0011] Preferably, two parallel pins installed horizontally and in parallel are installed at one end of the channel steel template, and a stop pin installed vertically is installed at the other end, and a gap is left between the stop pin and the side wall of the channel steel template for the parallel pin to pass through.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model, through the structural arrangement of two cross bars and through grooves, can pass one of the cross bars through the through groove, and then rotate the cross bar, and use the channel steel template itself to form a barrier between the two cross bars, thereby achieving clamping. At the same time, the design of the spring and the design of the distance between the two cross bars make it more convenient to rotate the cross bar after passing through the through groove, and then clamp the channel steel template, thereby achieving the fixation of the end position of the fixed steel wire. The other end of the fixed steel wire is fixed to the paving surface by a fixed steel nail. When the mixture is spread and rolled, the mixture gives an inward pulling force to the channel steel template through the fixed steel wire, and the template is prevented from moving outward, thereby ensuring the reinforcement effect. Compared with the prior art, the structure effectively improves the construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 The new type of inner pull-type steel formwork installation structure includes a channel steel formwork 1, a fixed steel wire 2 and a fixed steel nail 3. One end of the fixed steel wire 2 is provided with two cross bars 4, and the two cross bars 4 are arranged in parallel, and the other end is hook-shaped. A plurality of through grooves 5 are opened on the side wall of the channel steel formwork 1. The size of the through grooves 5 is adapted to the shape and size of the cross bars 4, and the two cross bars 4 are respectively located on both sides of the side wall of the channel steel formwork 1. The fixed steel nail 3 passes through one end of the fixed steel wire 2 and is fixed on the water-stable base;

[0022] A plug-in sleeve 6 is installed in the middle of one of the cross bars 4, and a plug-in rod 7 is installed in the middle of the other cross bar 4, and a spring 8 is installed at the end of the plug-in rod 7, the spring 8 is located in the plug-in sleeve 6, and the other end of the spring 8 is fixedly connected to the inner end of the plug-in sleeve 6, the cross-sections of the end of the plug-in rod 7 and the end of the inner cavity of the plug-in sleeve 6 are both rectangular, which is convenient for limiting the position of the plug-in rod 7 and preventing the plug-in rod 7 or the plug-in sleeve 6 from rotating relative to each other. The spacing between the two cross bars 4 is slightly smaller than the thickness of the through groove 5, for example, the spacing between the two cross bars 4 is less than 2 mm of the thickness of the through groove 5, and the two cross bars 4 are both cylindrical. The cylindrical design can make the cross bar 4 have an arc, which can reduce the friction between it and the channel steel template 1 during rotation, and facilitate the rotation of the two cross bars 4.

[0023] When the device is in use, through the structural arrangement of the two cross bars 4 and the through slots 5, one of the cross bars 4 can be passed through the through slots 5, and then the cross bar 4 can be rotated, and the channel steel template 1 itself can be used to form a barrier between the two cross bars 4 to achieve clamping. At the same time, the design of the spring 8 and the design of the distance between the two cross bars 4 make it more convenient to rotate the cross bar 4 after passing through the through slots 5, and then clamp the channel steel template 1 (the process is: the spring 8 is in a state of no force, the distance between the two cross bars 4 is slightly smaller than the thickness of the through slots 5, and the cross bar 4 passes through the through slots 5. When rotating through the through groove 5 and contacting with the edge of the through groove 5, the insertion rod 7 moves in the insertion tube 6, and the spring 8 is stretched to a certain extent until the rotation is completed). The two cross bars 4, under the action of the spring 8, realize the fixation of the end position of the fixed steel wire 2. The other end of the fixed steel wire 2 is fixed to the paving surface by the fixed steel nail 3. When the mixture is paved and rolled, the mixture gives an inward pulling force to the channel steel template 1 through the fixed steel wire 2, and the template is prevented from moving outward, thereby ensuring the reinforcement effect. Compared with the existing technology, this structure effectively improves the construction efficiency.

[0024] In this embodiment, the length of the fixing steel wire 2 is between 40-50 cm and the diameter is 4 mm.

[0025] In this embodiment, there are three through grooves 5, which are respectively located on both sides and the middle of the side wall of the channel steel template 1. The through grooves 5 are rectangular, with a length of 5 cm and a width of 1 cm.

[0026] In this embodiment, a bolt 9 is movably penetrated and connected to the middle part of the cross bar 4, and the end of the bolt 9 is movably penetrated through the insertion rod 7 to the insertion tube 6, and is screwed to the inner end of the insertion tube 6 through a threaded hole. Through the bolt 9, after one end of the cross bar 4 is fixed on the channel steel template 1 by fixing the steel wire 2, the insertion rod 7 is fixed in the insertion tube 6, thereby locking the two cross bars 4 on the channel steel template 1.

[0027] In this embodiment, two parallel pins 10 installed horizontally and in parallel are installed at one end of the channel steel template 1, and a stop pin 11 installed vertically is installed at the other end. A gap is left between the stop pin 11 and the side wall of the channel steel template 1 for the parallel pin 10 to pass through. When two channel steel templates 1 are supported, the two channel steel templates 1 can be connected into a whole through the parallel pins 10 and the stop pins 11.

[0028] In this embodiment, a rotating block 12 is installed on the outer side of the cross bar 4 , and the rotating block 12 is designed to be flat, which is convenient for rotating the cross bar 4 , and the bolt 9 is movably penetrated from the outer side of the rotating block 12 to the corresponding cross bar 4 .

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
