Examples

As shown in fig. 1 and 2, the embodiment of the present application provides a side form 100, in which the side form 100 fixes the reinforcing steel bar 200 extending from the prefabricated part 300 when the prefabricated part 300 is manufactured, and in addition, a concrete casting process is generally adopted when the prefabricated part 300 is manufactured, so that the outer form 100 also serves as a part or all of a casting mold to ensure casting molding of the prefabricated part 300.

The side mold 100 includes side mold blocks 10 and a cross bar 20, the number of side mold blocks 10 being at least two, the side mold blocks 10 being arranged side by side along a first preset direction a. The reinforcing bars 200 of the prefabricated part 300 are protruded from between the adjacent two side modules 10 and are clamped and fixed between the adjacent two side modules 10. The cross bar 20 is configured to fixedly connect at least two side mold blocks 10 such that the side mold blocks 10 remain arranged side by side in the first preset direction a.

In the present application, at least two means two or more other numbers.

The edge mould block 10 comprises a body 11 and two resilient seals 12, the body 11 functioning as: the bodies 11 of all the side mould blocks 10 are assembled side by side in a first predetermined direction a to form the boundary of the concrete prefabricated element 300 at the time of casting. The body 11 should be made of a metal material such as steel or iron with high rigidity and strength.

As shown in fig. 3 to 5, two elastic sealing members 12 are respectively fixed on two sides of the body 11 in the first preset direction a, and one elastic sealing member 12 of one side mold block 10 of the two adjacent side mold blocks 10 and the elastic sealing member 12 of the other side mold block 10 of the two adjacent side mold blocks 10 are mutually pressed in the first preset direction a to realize sealing between the two adjacent side mold blocks 10 so as to prevent slurry leakage during casting production of the side mold 100. When the two elastic sealing elements 12 are pressed, the contact position of the elastic sealing elements 12 and the steel bars 200 is directly extruded and deformed with the steel bars 200 to wrap and fix the steel bars 200, and the sealing effect can be achieved at the extending position of the steel bars 200 to prevent slurry leakage of the side mold 100 during casting production. The adjacent two side mold blocks 10 of the side mold 100 can achieve sealing of the adjacent two side mold blocks 10 while fixing the reinforcing bars 200.

The elastomeric seal 12 should be made of a highly resilient flexible material such as rubber, silicone, latex, high density sponge, and the like. The elastic sealing member 12 should be detachably connected to the side of the body 11 along the first predetermined direction a so as to facilitate replacement of the elastic sealing member 12.

The dimensions of the side mold blocks 10 of the same side mold 100 in the second preset direction B and the third preset direction C are the same, and the dimensions of the first preset direction a may be the same or different. If the dimensions of the body 11 and the elastic sealing member 12 are different in the first preset direction a, the side mold 100 can adapt to the fixation of the reinforcing bars 200 with different pitches. The dimensions of the edge mold blocks 10 in the first preset direction a depend on the fundamental modulus of the spacing of the bars 200, for example, when the spacing of the bars 200 is 100mm, 150mm, 200mm, 250mm, etc., then different numbers of edge mold blocks 10 having dimensions of 50mm, 100mm, 200mm in the first preset direction a can be made according to the frequency of occurrence of the spacing, and all the desired spacing of the bars 200 can be combined by these edge mold blocks 10. The first preset direction A, the second preset direction B and the third preset direction C are perpendicular to each other.

In the present embodiment, as shown in fig. 6 and 7, the cross bar 20 includes a first clamping portion 21 and a second clamping portion 22, the first clamping portion 21 and the second clamping portion 22 are hinged, and the first clamping portion 21 is rotatable relative to the second clamping portion 22 about an axis extending in a first preset direction a to provide the cross bar 20 with a closed state and an open state; when the cross bar 20 is in the closed state, the first clamping portion 21 and the second clamping portion 22 jointly clamp each two side modules 10 to fixedly connect the at least two side modules 10. The clamping and fixing with the side module 10 are realized by the way that the first clamping part 21 and the second clamping part 22 are opened and closed, and the fixing way is simple and reliable.

The fact that the cross bars 20 fixedly connect the side mold blocks 10 means that the cross bars 20 maintain the positions of the side mold blocks 10 in the first preset direction a, the second preset direction B and the third preset direction C relatively fixed, so that the adjacent two side mold blocks 10 can stably clamp the reinforcing steel bars 200 and maintain the sealing performance between the adjacent two side mold blocks 10.

This fit is particularly applicable to side forms 100 that are longer in dimension in the first predetermined direction a. For example, in some cases, the cross bar 20 is in a whole bar structure (rod structure), the cross bar 20 in the whole bar form sequentially passes through the mounting holes on the side mold blocks 10 along the first preset direction a, if the number of the side mold blocks 10 of the side mold 100 is large, the side mold 100 is large in the first preset direction a, or in the process of sliding fit between the cross bar 20 and the mounting holes on the side mold blocks 10 due to no pre-fixing between the side mold blocks 10, the side mold blocks 10 are easy to move due to friction, and a large force needs to be applied to push the cross bar 20, so that the assembly difficulty of the side mold 100 is increased. By clamping the side mold blocks 10 together by the first clamping part 21 and the second clamping part 22 of the cross bar 20, all the side mold blocks 10 can be kept in a relatively fixed state without overcoming the friction force between the cross bar 20 and the side mold blocks 10, so that the structural stability of the side mold 100 and the fixing capability to the reinforcing steel bar 200 are improved.

In the present embodiment, the first clamping portion 21 and the second clamping portion 22 are identical in structure.

In other embodiments, the first clamping portion 21 and the second clamping portion 22 may be configured differently and may be configured according to the actual situation and the configuration of the edge mold block 10.

In order to facilitate the cooperation of each side die block 10 with the first clamping portion 21 and the second clamping portion 22 of the cross bar 20, one end of the body 11 located in the second preset direction B is provided with a positioning portion 13, and the positioning portion 13 is used for cooperating with the first clamping portion 21 and the second clamping portion 22 when the cross bar 20 is in the closed state so as to fixedly connect at least two side die blocks 10; the first preset direction A is perpendicular to the second preset direction B. The positioning portion 13 may be integrally formed with the body 11, or may be detachably or fixedly mounted on one end of the body 11 in the second preset direction B after the body 11 is formed. The positioning part 13 is arranged to facilitate the matching of each side mold block 10 with the cross bar 20, so that the cross bar 20 can fix each side mold block 10, and the fixing of the side mold 100 to the steel bar 200 and the sealing performance between two adjacent side mold blocks 10 are ensured.

In this embodiment, the positioning portion 13 is a guide rail, and the guide rail extends along the first preset direction a; the cross bar 20 is provided with a clamping groove 23, the clamping groove 23 extends along a first preset direction A, and each guide rail can be clamped into the clamping groove 23; the clamping groove 23 is used for being matched with the guide rail when the cross bar 20 is in the closed state so as to fixedly connect at least two side modules 10. The cross bar 20 provided with the clamping groove 23 can slide along the first preset direction A relative to the guide rail so as to realize the matching of each positioning part 13 and the cross bar 20, and the matching mode is simple, and the connection is convenient and labor-saving.

In addition, the cross bar 20 is configured to include the first clamping portion 21 and the second clamping portion 22 capable of rotating relative to each other, so that the step of aligning the clamping groove 23 with the guide rail in the first preset direction a is not required, and the first clamping portion 21 and the second clamping portion 22 can clamp the positioning portion 13 from two sides of the third preset direction C respectively, so that the fixing manner is simple and labor-saving.

The dimensions of the cross bar 20 in the first predetermined direction a should not be less than the sum of the dimensions of all edge mold blocks 10 in the first predetermined direction a.

The guide rail is mainly used for connecting and fixing the relative positions of the mold blocks 10 at each side so as to adapt to different rib-out intervals. The rails may take the form of dovetails as shown, or other reliable forms, but are matched to the composite rail 20. The guide rail can be made of metal materials.

In other embodiments, the positioning portion 13 may be provided with a clamping groove 23, and the cross bar 20 is provided with a guide rail for matching with the clamping groove 23.

In other embodiments, the positioning portion 13 may also be an insertion hole disposed on two sides of the side mold block 10 along the third preset direction, the first clamping portion 21 and the second clamping portion 22 are respectively provided with a latch matched with the insertion hole, when the cross bar 20 is in the closed state, the latches on the first clamping portion 21 and the second clamping portion 22 are respectively inserted into the corresponding insertion holes, and the connection of the side mold blocks 10 through the cross bar 20 can also be realized.

In other embodiments, each side mold block 10 may be secured to the cross bar 20 by bolts, screws, or the like.

The first clamping portion 131 is a protrusion, and the second clamping portion 211 and the third clamping portion 221 are grooves. The arrangement of the first clamping portion 131 and the second clamping portion 211 makes the matching of the cross bar 20 and the positioning portion 13 more stable, so that the structural stability of the side mold 100 can be further improved, and the sealing capability of the side mold 100 and the fixing capability of the reinforcing steel bar 200 are ensured. The matching mode of the bulges and the grooves is simple and the stability is good.

In other embodiments, the first clamping portion 131 may be a groove, and the second clamping portion 211 and the third clamping portion 221 may be protrusions.

In preparing the preform, the platen 14 is located on the side of the body 11 remote from the preform 300. The pressing plate 14 and the body 11 may be integrally formed, or the pressing plate 14 may be detachably mounted on the body 11 by a screw, a bolt, or the like, or may be fixedly connected to the body 11 by welding or the like.

The thickness of the pressing plate 14 should not be less than 2mm, and may be made of the same metal material as the body 11, but the materials of the pressing plate 14 and the body 11 may be different. The dimension of the pressing plate 14 in the third preset direction C is about half the dimension of the body 11 in the second preset direction B, and the dimension of the pressing plate 14 in the first preset direction a is preferably 30-50mm.
