Description

Steel chisel for producing aerated concrete plate

Technical Field

The utility model relates to the technical field of building processing equipment, in particular to a steel drill rod for producing an aerated concrete plate.

Background

The aerated concrete plate is a common building member, and the application of the aerated concrete plate is continuously developed along with the development of building industries such as real estate and the like in recent years, and the production is advanced to gradual automation and scale. Compared with building components such as aerated concrete brickwork of a precursor of the common aerated concrete slab in the existing market, the aerated concrete slab has longer length and larger stressed area, so that the formed slab has stronger stability and structural strength, is generally matched with a reinforcing mesh for forming according to requirements during production and manufacture, and is used as a bearing support framework of the slab to bear dead weight and share most of external load after building construction. When the aerated concrete plate is used as a wall panel, a floor panel and a roof panel, a corresponding number of reinforcing steel meshes are arranged in the aerated concrete plate during manufacturing and forming according to corresponding construction requirements. The structure of the reinforcing steel bar net sheet is generally woven by criss-cross reinforcing steel bars to form a grid structure, and the specific details and specifications including the diameters of the reinforcing steel bars, the mesh size of the net sheet, the rust prevention requirement and the like are correspondingly changed according to the construction and use requirements of different application scenes.

When the aerated concrete plate is manufactured, the adjacent reinforcing steel meshes are generally connected by a middle connecting piece (a connecting piece with a plastic buckle iron H-shaped structure is generally adopted as the middle connecting piece) made of plastic or iron, the connecting structure uses steel bars to bear the middle connecting piece to form a matching structure to stabilize the reinforcing steel meshes, and the steel bars can be recycled after the plate is formed. Fig. 10 shows a structural layout of mutually connecting adjacent reinforcing steel meshes through a matching structure of steel bars 3 'and intermediate connectors 2' (before pouring of plates), so as to ensure stability of the reinforcing steel meshes during pouring of plates (only the connecting structure between the two adjacent reinforcing steel meshes is shown in the figure, and more reinforcing steel meshes with corresponding number can be distributed along the horizontal direction according to corresponding forming requirements in actual production), wherein the matching structure is made of steel bars 3 'and intermediate connectors 2' (referred to as plastic buckles or iron H-shaped connecting pieces), the mesh 101 'and the mesh 102' are connected together through the intermediate connectors 2', the intermediate connectors 2' (temporarily) are fixedly suspended on the steel bars 3', and after the concrete blank is poured, the steel bars 3' are pulled out after the blank is solidified and shaped.

Fig. 11 shows a plastic buckle structure with a through hole 20201' for the drill rod to pass through and two mounting ends 20202' for the steel rod to be clamped in, wherein the two mounting ends 20202' are respectively positioned on two opposite sides of the through hole 20201', and the clamping inlet 20204' of any mounting end 20202' is arranged upwards according to the illustrated structure direction (fig. 12 shows that the structure is only one typical application of the matching structure of the plastic buckle and the drill rod, in the structure arrangement, the plastic buckle positioned above is inverted to clamp the steel rod from top to bottom, while the plastic buckle positioned below is arranged according to the structure direction shown in fig. 11 to clamp the steel rod from bottom to top), and the mounting end 20202' is connected with the side wall of the edge of the hole where the through hole 20201' is positioned through a (horizontal) connecting rod 20203 '. An opening at one side (lower side in the illustrated example) of the through hole 20201' is provided with a claw-shaped holding structure 20205' having elasticity, by which the drill rod is gripped after penetrating the through hole 20201 '. After the plate is cast and formed, the through holes 20201 'are spread due to expansion caused by heat and contraction caused by cold, so that the clamping effect of the clamping structure 20205' is invalid, and the steel bars can be recovered and reused after being pulled out. Fig. 12 shows a cooperation structure of steel bars and plastic buckles, wherein the plastic buckles 202' in the structure are used for bearing reinforcing bars of two adjacent reinforcing steel meshes through mounting structures at two ends, and in order to prevent the meshes from shaking after hanging, one plastic buckle 202' can be arranged at the upper part and the lower part of each steel bar 3'. The formation of such mating structures also requires a skilled operator to ensure that the plastic fastener is located at a specific position on the steel shank after the drill rod is inserted into the hole of the plastic fastener.

In summary, the conventional scheme has the following disadvantages:

1) The intermediate connection consumes a large amount: at least one plastic fastener is required for a corresponding steel bar (in some cases, when the upper and lower height dimensions of the net sheet are larger, one plastic fastener is generally arranged at the upper part and the lower part of the steel bar respectively, so that one steel bar is correspondingly provided with two plastic fasteners)

The adjacent net sheets are fixed, and as the plastic buckles cannot be recovered, the consumption of the plastic buckles is large under the condition that the plate has a longer scale, so that the manufacturing cost of the plate cannot be controlled well;

2) The manual consumption is large: the cooperation between plastics buckle and the drill steel needs to consume more manual work, wastes time and energy, when using iron H type connection piece, because the both ends of connection piece generally need weld to the reinforcing bar strip of adjacent reinforcing bar net piece, consequently still need to prepare welding equipment for this, still require operating personnel to possess welding skill simultaneously.

Referring to fig. 1, the drill steel for producing an aerated concrete panel comprises a drill steel body 1 and a clamping piece 2. Wherein, drill steel body 1 is upright rod-like structure, and clamping piece 2 connects drill steel body 1.

As shown in fig. 3, the clamping member 2 has a clamping portion 201, and the clamping portion 201 has elasticity. As shown in fig. 1 and 3, a downward bayonet 3 is formed between the clamping part 201 and the drill rod body 1;

the reinforcement bars 901 of the reinforcement mesh are clamped between the clamping piece 2 and the rod body of the steel rod body 1 from the bayonet 3 from bottom to top, so that the clamping piece 2 and the rod body of the steel rod body 1 are clamped.

After the steel bar mesh 9 is arranged according to the example, as shown in fig. 2, the clamping piece is matched with the rod body of the steel bar body to clamp the steel bar mesh 9. After the blank is poured between the reinforcing steel bar meshes which are kept stable under the combined action of the steel bar bodies and the clamping pieces, the blank and the reinforcing steel bar meshes are integrally formed into an aerated concrete plate, and the whole construction process is free of welding of connecting pieces, binding of buckles and other operations relative to the traditional process, so that the technical requirements of corresponding labor and operators are omitted, and consumable input of the connecting pieces or the buckles is also saved.

The utility model is provided with the clamping piece according to the following structure: in some of these embodiments, as shown in figure 3,

the clamping piece 2 comprises a clamping part 201 and a fixing part 202, wherein the fixing part 202 is connected with the rod body of the steel drill body 1, the clamping part 201 is of an S-shaped structure, and the upper end of the clamping part is connected with the fixing part 202, and a bayonet 3 is formed between the lower end of the clamping part and the rod body of the steel drill body 1 after the lower end of the clamping part is turned outwards.

As shown in fig. 1, the reinforcing bars 901 of the mesh reinforcement 9 are engaged with the bayonet 3, and then are finally restrained to the upper part of the S-shaped structure of the clip 201 (between the clip and the drill body).

In some embodiments, when the clamping piece is arranged, the fixing portion is attached to the outer wall of the shaft of the drill steel body, and the length of the fixing portion is greater than that of the clamping portion.

The length of the fixing portion and the clamping portion here refers to the length dimension in the vertical direction (along the length of the shaft) in the structure shown in fig. 1 (the length of the S-shaped structure of the clamping portion refers to the shortest distance between the upper end and the lower end of the S-shaped structure).

According to the utility model, the fixing part of the clamping piece is longer than the clamping part, and the clamping force of the clamping piece to the outer wall of the rod body of the steel rod body is enhanced by enabling the clamping piece to be attached to the rod body of the steel rod body, so that the fixing effect of the clamping piece on the steel rod body is enhanced, and the problem that the clamping piece and the steel rod body are easy to separate from each other due to the action of external force is solved in use. It should be noted that, to enhance the connection strength of the structure, the clamping member body and the drill rod body may be fixed by two surrounding portions as shown in fig. 7. Alternatively, the fixing part can be fixed on the rod body of the steel drill body by adopting a welding or binding mode.

In some embodiments, the fixing portion and the clamping portion are provided as an integrally formed structure, that is, they are integrally formed at the time of manufacture.

In other embodiments, the fixing portion and the clamping portion are separately manufactured and formed and then welded together.

The utility model further strengthens the clamping effect on the reinforcing steel mesh after being arranged by the following structure, and simultaneously ensures that the mesh is askew caused by shaking generated by inertia in the process of transferring and placing the reinforcing steel mesh in a pouring area by the suspension equipment: as shown in fig. 1 and 8, in some embodiments, a notch 1001 is formed at the lower end of the drill steel body 1, and then the lower end is formed into a notch end 101, where the notch 1001 and the clamping member 2 are located on the same side of the shaft of the drill steel body 1.

After the vertical projection of the shaft structure where the notch end 101 is positioned is enabled to fall into the vertical projections of the rest (without notches) of the shafts, namely, when the steel drill body is vertically placed, the vertical projection falls into the vertical projection in the horizontal plane right below the steel drill body, and the projection of the shaft where the notch end is positioned is enabled to fall into the projections of the rest (without notches) of the shafts. For example, as shown in fig. 1, when the shaft of the drill steel body is formed into a cylindrical structure, the vertical projection of the shaft where the notch end 101 is located in the vertical projection of the shaft of the drill steel body 1 (at this time, the vertical projection of the shaft of the drill steel body 1 is in a circular shape, the vertical projection of the notch end 101 is in a fan shape, and a part of the edge of the vertical projection of the shaft of the drill steel body 1 coincides with a part of the edge of the vertical projection of the shaft).

In this example, the notch end may be configured as follows: as shown in fig. 8, on the steel bar body 1, between the lower outer wall of the bar body and the lower end face of the steel bar body 1, after a notch 1001 with a step structure is formed after removing part of the structure of the outer wall of the bar body, the rest bar body structure is formed into a notch end 101, so that the rest bar body structure is a tip end relative to the bar body of the rest steel bar body without a notch on the whole, and when the tip end is clamped with the steel bar net piece from top to bottom, the tip end can conveniently wind from one side to the other side of the steel bar at the lowest part of the net piece.

The notch end is arranged to be matched with the clamping part up and down to clamp the whole reinforcing steel bar net, so that the clamping effect of the clamping part on reinforcing steel bars of the reinforcing steel bar net is achieved, the clamping effect of the clamping part on the whole reinforcing steel bar net is achieved by matching the notch end with the rod body of the steel bar body, and the effect of stabilizing the reinforcing steel bar net is achieved better under the action of double clamping effects.

Specifically, as shown in fig. 1 and 2, when the clamping member 2 clamps the steel bar on the left side of the steel bar body 1 at the upper position of the steel bar mesh 9; in the lower position of the reinforcing mesh 9, the notch end 101 is located on the left side of the reinforcing bar at the lowest position of the reinforcing mesh 9, at this time, both the notch end 101 and the clamping member 2 are located on the same side of the reinforcing mesh 9, and the shaft of the drill rod body 1 is located on the opposite side (the illustrated structure is the right side). In operation, as shown in fig. 2, the steel bar body 1 is located on the right side of the steel bar mesh 9, the uppermost steel bar of the steel bar mesh 9 is clamped between the clamping piece 2 and the rod body of the steel bar body 1 from top to bottom, the lower notch end 101 bypasses the lowermost steel bar of the steel bar mesh 9 from the right side of the steel bar mesh 9 by using the tip formed by the smaller cross section of the lower notch end relative to the rod body of the steel bar mesh 1 and is located on the left side of the steel bar mesh 9, so that the clamping piece 2 and the notch end 101 are located on the left side of the steel bar mesh 9, and the rod body of the steel bar mesh 1 is located on the right side of the steel bar mesh 9, thereby forming the clamping effect on the whole structure of the mesh.

In some embodiments, the clamping piece of the utility model can be welded to the outer wall of the shaft of the drill steel body through the fixing part of the clamping piece, so that the clamping piece is fixedly connected with the drill steel body.

After the steel bar body clamping device is arranged according to the following structure, the clamping piece is ensured to be fixed on the outer wall of the steel bar body, and meanwhile, the damage to a blank body when the steel bar body is pulled out is effectively reduced: in some embodiments, as shown in fig. 3 and 6, the clamping member 2 includes a surrounding portion 203, the surrounding portion 203 is connected to the fixing portion 202, and the surrounding portion 203 has a ring structure, and the surrounding portion 203 is wound on the rod body of the drill steel body 1.

As shown in fig. 4 and 5, an annular recess 103 is formed on the outer wall of the shank of the drill steel body 1, and the surrounding portion 203 is embedded in the annular recess 103.

In this example, the destructive effect on the blank body when the drill steel body is pulled out can be further reduced by the following arrangement: as shown in fig. 4 and 5, the outer wall of the shaft of the drill steel body 1 is provided with a vertical recess 104, and the upper end of the vertical recess 104 is connected (communicated) with an annular recess structure 103.

In this example, the length of the vertical recess 104 is not less than the sum of the length of the fixing portion 202 and the length of the clamping portion 201, so that the fixing portion 202 and the clamping portion 201 are embedded in the vertical recess 104 after the surrounding portion 203 is disposed in the annular recess structure 103.

Even when the clamping portion 201 is fitted in the vertical recess 104, a bayonet 3 is formed between the lower end of the clamping portion and the outer wall of the drill rod body after the lower end is turned outward.

According to the utility model, the surrounding part is arranged to connect the fixing part, and the vertical recess is arranged on the outer wall of the rod body of the steel drill body to embed the fixing part, so that most of the structure of the clamping piece is retracted into the recess structure (comprising the vertical recess and the annular recess structure) on the rod body to a large extent, the matching structure formed by the steel drill body and the clamping piece has a relatively consistent external width dimension, and when the steel drill body is pulled out from the blank, the clamping piece is basically embedded into the recess structure of the rod body, so that the damage effect of the clamping piece on the blank can be effectively controlled, and the problems of fragmentation of the blank during transportation or use and the like caused by the damage of the clamping piece from the inside of the blank are also reduced.

The utility model relates to a steel drill body, which is used for enhancing the connection strength between a clamping piece and the steel drill body, and can be arranged according to the following structure: in some embodiments, the outer wall of the drill steel body is provided with at least two annular concave structures, the clamping piece comprises at least two surrounding parts corresponding to the annular concave structures one by one, and when the clamping piece is connected with the drill steel body, any surrounding part is embedded into the annular concave structure corresponding to the clamping piece.

In some preferred embodiments, as shown in fig. 7, the outer wall of the shaft of the drill steel body is provided with two annular concave structures with an upper interval and a lower interval, wherein the two annular concave structures comprise an annular concave structure 103-1 positioned at the upper part and an annular concave structure 103-2 positioned at the lower part, the clamping piece comprises two surrounding parts, and the upper interval and the lower interval of the two surrounding parts are respectively connected with the upper part and the lower part of the fixing part.

In the implementation of the utility model, the steel mesh is not easy to shake after being connected with the steel mesh after being arranged according to the following structure: in some embodiments, the shank outer wall of the drill steel body is a wavy outer wall. The lower outer wall of the steel bar body is of a wavy structure, so that the steel bar body is easy to enable the steel bar body to be in a wavy structure when corresponding to reinforcing steel bar meshes of different lattice hole sizes, the steel bars located below can lean on the wavy outer wall, and part of the steel bars fall into the trough of the wavy structure through the wavy structure, so that a certain positioning effect is achieved between the rod body of the steel bar body and the reinforcing steel bar meshes, a certain adhesion effect is achieved between the meshes and the rod body of the steel bar body to a certain extent, and the shaking influence is relieved. In some preferred embodiments, as shown in figure 8, the outer wall of the shank below the clamping members 2 is provided as an outer wall 102 of undulating configuration on the drill body 1, which facilitates the leaning of the bars 902 on the reinforcing mesh 9 (as opposed to the bars 901 clamped by the clamping members, the other bar in the gap 1001 in figure 8 being unlabeled, which is typically the lowermost bar of the mesh) within the valleys of the outer wall 102.

The utility model aims to enhance the stability of the net sheet after being connected with steel bars, and can be arranged according to the following structure: in some embodiments, the shank of the drill steel body is provided with at least two clamps.

In some preferred embodiments, the shank of the drill steel body is provided with two clamping members, one on each of the upper and lower outer walls of the shank.

In the above example, the upper outer wall and the lower outer wall refer to the shaft outer wall located above the boundary position being the upper outer wall, and the shaft outer wall located below the boundary position being the lower outer wall, with 1/2 of the length of the shaft being the boundary position (that is, half of the entire length of the shaft of the drill steel body being the boundary position).

The detachable connection of the steel bar body and the clamping piece can be realized according to the following structure, so that when the clamping piece cannot be pulled out along with the steel bar body due to abnormal reasons after casting and shaping of a blank, the steel bar body can be pulled out easily by separating the clamping piece from the steel bar body: in some embodiments, the drill steel body and the clamping member are provided in a detachable structure.

In this example, the detachable structure may be specifically configured as follows: as shown in fig. 9, a first through hole 105 in a horizontal direction is formed in the shank of the drill steel body 1, and the upper end of the fixing portion is turned over by 90 degrees to be horizontal and then passes through the first through hole 105, so that the fixing portion is fixedly connected with the shank. The end 20201 of the penetrating fixing portion may be turned upwards or downwards to form a self-locking structure, so as to prevent the fixing portion from being separated from the first through hole 105.

The shaft of the drill steel body 1 has a vertical inner cavity 106, and the first through hole 105 penetrates the inner cavity 106.

When the abnormal reasons cause that the clamping piece cannot be pulled out smoothly along with the steel drill body 1, the cutter 8 with the cutting edge at the lower end of the cutter can extend into the inner cavity of the rod body, the fixing part penetrating into the first through hole 105 is vertically cut down, and when the steel drill body 1 is pulled up from the shaped blank body, the clamping piece 2 after cutting can be left in the blank body under the condition of reducing the damage to the blank body.

According to the utility model, the steel bar body and the clamping piece are arranged to be of a detachable structure, and the clamping piece is kept in the plate structure after casting and shaping in a mode of separating the clamping piece from the steel bar body under the condition that the clamping piece is not easy to take out due to special reasons, so that the steel bar body is pulled out under the condition that the plate structure is not damaged, and the pulled-out steel bar body can be quickly and conveniently provided with a new clamping piece again for reuse.

In summary, after the traditional steel drill structure is improved, an independent elastic clamping structure (the clamping piece can be made of a steel wire spring and is an integral structure with a clamping part and a fixing part) is arranged on the steel drill, the steel bars on the steel bar net sheet are plugged into the bayonets by utilizing the elasticity of the clamping piece, the clamping structure clamps the steel bars on the net sheet, then concrete pouring is carried out, and the net sheet is fixed by the blank after the blank is hardened; because the bayonet of the clamping structure is downwards arranged, when the steel drills are pulled up upwards, the steel reinforcement meshes can be conveniently separated from the clamping structure. Compared with the traditional steel structure, the steel structure does not need to be matched with intermediate connection structures such as a plastic buckle or an H-shaped connecting sheet, so that the material cost is saved, the manual and technical requirements for arranging the intermediate connection structure are eliminated, and the overall construction cost is indirectly reduced.

The foregoing has shown and described the basic principles and main features of the present utility model and the advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims.
