Fig. 7 is a view in the direction C of fig. 6. Referring to fig. 7, the force-receiving template 100 in the present embodiment has a third surface 103 opposite to the first surface 101. In this embodiment, the first surface 101 is formed by two inner sides of the angle steel of the force receiving form 100, and the third surface 103 is formed by two outer sides 204 of the angle steel of the force receiving form 100. In order to facilitate the positioning and connection of the connecting templates 200 on the stress template 100, a row of studs 130 distributed along the extending direction 012 of the stress template 100 is respectively connected to the third surfaces 103 of the two side plates 110 forming the stress template 100. The studs 130 may be welded directly to the force receiving template 100 or may be threaded into the force receiving template 100.

Fig. 8 is a schematic structural diagram of the connection template 200 and the force-receiving template 100 in this embodiment before connection, and shows the positional relationship between the connection template 200 and the force-receiving template 100 before connection in an exploded form. Referring to fig. 8, the outer side 204 of the second connecting plate 222 of the connecting template 200 and the second surface 201 of the connecting template 200 are parallel and staggered to form a matching step, and the height of the step (i.e. the distance between the outer side 204 of the second connecting plate 222 of the connecting template 200 and the second surface 201 of the connecting template 200) is equal to the plate thickness of the side plate 110 of the stressed template 100.

Fig. 9 is a schematic structural diagram of the force-receiving template 100 and the connection template 200 in fig. 8 after the connection is completed. Referring to fig. 9 (see fig. 8), two connecting templates 200 are respectively connected to the two side plates 110 of the force-bearing template 100. The second connecting plate 222 is detachably connected to the stressed formwork 100 in a manner that a connecting hole 223 is formed in the second connecting plate 222 of the connecting formwork 200, the connecting formwork 200 is sleeved on the stud 130 from the connecting hole 223, and the connecting formwork 200 is fixed to the stressed formwork 100 through threaded connection of the connecting nut 131 and the stud 130. At this time, the second surfaces 201 of the respective coupling forms 200 are coupled to form the sub-work surfaces 202, and the sub-work surfaces 202 and the first surfaces 101 are coupled to each other to form a continuous main work surface 013 for forming the surface of the concrete member.

The number of sides of the column formed by the concrete cast-in-place column combination mold 001 is four, and the main working surface 013 is a rectangular cylinder. The number of sides of the concrete column formed by the cast-in-place concrete column combination mold 001 in this embodiment can be adjusted by increasing or decreasing the number of the stressed templates 100 and the corresponding connecting templates 200. For example, fig. 10 is a schematic view of a concrete cast-in-place column combination mold 001 when the number of the stress templates 100 is increased to six. At this time, the first closed path 011 is a hexagonal side line, the formed column is a hexagonal column, and the main working surface 013 is a hexagonal cylinder; the corresponding force-bearing templates 100 are six, and the corresponding connecting templates 200 are six rows. When the cross section of the formed column is a regular hexagon, each stress template 100 is composed of two side plates 110 with an included angle of 120 degrees, and the stress template 100 of the rectangular column mold is an angle steel composed of two side plates 110 with an included angle of 90 degrees. The column with the least number of sides that can be molded by the cast-in-place concrete column composite mold 001 in this embodiment is a triangular column.

Referring to fig. 11, the cast-in-place concrete column combination mold 001 of the present embodiment can also be used to form a circular column, i.e. the main working surface 013 is cylindrical. The embodiment is that each connecting template 200 is configured to have a structure with a proper radian, accordingly, the two side plates 110 of each force-bearing template 100 are not intersected at a certain angle, but the inner side surface and the outer side surface 204 thereof are respectively corresponding cambered surfaces, and after the force-bearing template 100 and the connecting template 200 are connected, a cylindrical main working surface 013 is formed. In fig. 11, the cast-in-place concrete column composite mold 001 for constructing a circular column uses four stressed formworks 100 and four rows of connecting formworks 200 in common, and in fact, the number of the stressed formworks 100 and the number of the connecting formworks 200 of the cast-in-place concrete column composite mold 001 for constructing a circular column may be any number greater than 2.

Referring to fig. 1 again, the height of the cast-in-place concrete column combination mold 001 in the extending direction 012 of the stressed template 100 in this embodiment can be adjusted by increasing or decreasing the number of the connecting templates 200. For example, when the height of the member to be poured is only half of the height of the force-receiving formworks 100, it is only necessary to install the connecting formworks 200 between the force-receiving formworks 100 to a height slightly higher than half of the height.

In this embodiment, since the two ends of the connecting form 200 are detachably connected to the adjacent stressed form 100, when concrete is poured and conditions allow (for example, the poured concrete member has a certain strength), the connecting form 200 at the part can be removed to facilitate heat dissipation of the concrete member or curing (for example, watering curing, heat preservation curing, etc.) of the concrete member, ensure the quality of the obtained concrete member, and reduce concrete defects such as expansion cracks. Furthermore, the connection template 200 which is detached in advance can be continuously used in a turnover way, so that the turnover rate of the connection template 200 is increased. Fig. 12 is a schematic structural view illustrating the cast-in-place concrete column assembly mold 001 of fig. 1 after a portion of the connecting formwork 200 is removed.

The main working surface 013 of the concrete cast-in-place column combined mould 001 can be coated with a coating formed by an antirust agent or a release agent and the like, so that the concrete mould 010 has better antirust performance and release performance, the service life of the combined mould is ensured, the demoulding is convenient, and the surface quality of a formed concrete member is ensured.

In the present embodiment, it is preferable that the shape and structure of each connecting template 200 are the same. The beneficial effects are that, be convenient for the batch production processing of connecting template 200, reduce design volume and the cost of single piece processing. The connecting templates 200 with the same structural shape can share one design drawing, the blanking and the subsequent processing can be carried out in batches, and the single piece processing cost and the production efficiency can be greatly reduced. Meanwhile, the connecting templates 200 have the same shape and structure, so that the connecting templates 200 have good interchangeability. In the using process, the connecting templates 200 which are deformed and failed due to external force action, corrosion and the like can conveniently obtain a substitute from the connecting templates 200 which are stored even if the concrete mould 010 is temporarily not used, and the influence on the normal use of the whole mould due to the damage or the loss of the connecting templates 200 at certain parts is avoided. In addition, in the service cycle of the concrete mold 010, the service performance and the service life of the concrete mold 010 can be maintained by appropriately replacing a new connecting template 200, and the connecting template 200 which can be normally used is prevented from being scrapped together with the whole concrete mold 010.

Each connecting template 200 of the concrete mold 010 in this embodiment is detachably connected to the corresponding stressed template 100. That is, all the connection forms 200 constituting the concrete form 010 are detachable, so that the respective stress forms 100 are also separable from each other, thereby facilitating storage, transportation and the like of components.

In addition, all the connecting templates 200 are detachably connected, and the sectional formwork supporting of the concrete member can be realized, so that the sectional pouring is realized. Specifically, in the process of pouring the concrete member, the stressed templates 100 are erected at a set position, the connecting templates 200 are installed between the stressed templates 100 from bottom to top to reach the height of a pouring section (at this time, the structure of the concrete mold 010 is shown in fig. 13), and then the first section of concrete can be poured; after the first section of concrete is poured, continuously upwards stacking and installing the connecting template 200 in the stressed template 100 to the height of the second pouring section, and then pouring the second section of concrete; and repeating the steps until the concrete column is poured. On one hand, the pouring mode can ensure that after each section of concrete is poured, the poured concrete has enough space for deformation and enough surface area for heat dissipation; simultaneously, the drop distance that every section was pour when pouring is all less, avoids the concrete to take place the segregation phenomenon and influences the quality of fashioned concrete member. In addition, the casting method has the most beneficial effect of high construction safety, especially for concrete members with extremely high height.

The supporting manner of the cast-in-place concrete column composite mold 001 in this embodiment may be that the mold is directly supported on the third surface 103 of the stressed template 100, and the connecting template 200 is connected to the stressed template 100 as a main stressed structure of the poured concrete.

In summary, the cast-in-place concrete column composite mold 001 in this embodiment forms a cylindrical structure through the multiple stressed formworks 100 and the multiple connection formworks 200 connected between the adjacent stressed formworks 100, and is used for forming a concrete column, and has at least the following beneficial effects:

the sectional shape and the size of the cast-in-place concrete column combined mould 001 in the embodiment can be conveniently adjusted to combine the cast-in-place concrete column combined mould 001 with a larger size or a smaller size or different shapes to form concrete columns with different sizes and sectional shapes;

in this embodiment, a part of the connecting template 200 of the cast-in-place concrete column combined mold 001 can be removed when needed, so that heat dissipation of a concrete member or maintenance of the concrete member is facilitated, the quality of the obtained concrete member is ensured, and concrete defects such as expansion cracks are reduced. In addition, the connection template 200 which is detached first can be continuously used in a turnover mode, and the turnover rate of the connection template 200 is increased.

EXAMPLE III

The present embodiment provides a cast-in-place concrete column and well hole combined mold 003, which is substantially the same as the cast-in-place concrete column combined mold 001 in the first embodiment or the cast-in-place concrete well hole combined mold 002 in the second embodiment, and the difference is that it is formed by assembling only two standard sectional materials, namely, channel steel and angle steel, and has extremely strong economical efficiency and practicability on the basis of having the beneficial effects of the first embodiment or the second embodiment. And the combined mould can be used as a column combined mould for forming a column or a well hole combined mould for forming a well hole respectively through different assembling modes.

Fig. 18 and 19 respectively show the structure schematic diagrams of the cast-in-place concrete column and well hole combined die 003 in the embodiment as the combined die of the forming column and the combined die of the well hole.

Referring to fig. 18 or 19, a cast-in-place concrete column and borehole assembly die 003 includes four stress templates 100 arranged in parallel at the four corners of a rectangular first closed path 011. The force-receiving form 100 is formed of a first angle bar 110' having a bar shape. The four first angles 110' form four corners of the rectangular first closed path 011, respectively, when viewed along the extending direction 012 of the force receiving die 100. A plurality of connecting templates 200 are provided between the adjacent force receiving templates 100, which are sequentially stacked in the extending direction 012 of the force receiving templates 100. The connection form 200 includes a second channel 210' and two second angles 220' connected to both ends of the second channel 210', respectively. The second angle 220' includes a first connection plate 221 and a second connection plate 222 perpendicular to each other. A first connecting plate 221 extends parallel to the bottom wall of the second channel 210 'and in a direction away from the second channel 210', and a second connecting plate 222 is welded to the end of the second channel 210 'and faces the slot of the second channel 210'. The outer surface of the first connection plate 221 is located between the outer surface of the bottom wall of the second channel 210 'and the notch of the second channel 210', and the distance between the outer surface and the bottom wall of the second channel 210 'is equal to the plate thickness of the first angle iron 110'.

The cast-in-place concrete column and well hole combined die 003 in the present embodiment is assembled by a stressed form 100 formed by four first angle steels 110' and a plurality of connecting forms 200 formed by connecting one second channel steel 210' and two second angle steels 220'. Fig. 20, 21, and 22 show the configuration of the first angle steel 110', the second channel 210', and the second angle steel 220', respectively. Optionally, the first angle steel 110', the second angle steel 220' and the second channel steel 210' are all formed by blanking and bending steel plates with a thickness of 5 mm. Fig. 23 and 24 are schematic structural views of the force-receiving template 100 and the connecting template 200, respectively.

When the cast-in-place concrete column and hole combination die 003 is assembled into a column combination die as shown in fig. 18, referring to fig. 25, each connecting form 200 is fitted between the adjacent load bearing forms 100 from the outside of the first closed path 011 inward, the outer surface of the bottom wall of the second channel section 210 'connects the inner surfaces of the first angle irons 110' at both sides thereof to form a cylindrical main work surface 013 facing the inside of the first closed path 011, and the main work surface 013 defines a space for forming a concrete column.

When the cast-in-place concrete column and well hole assembly die 003 is assembled into the well hole assembly die shown in fig. 19, referring to fig. 26, when each connecting form 200 is fitted between the adjacent stress forms 100 from the inside of the first closed path 011 toward the outside, the outer surface of the bottom wall of the second channel section 210 'connects the outer surfaces of the first angle irons 110' at both sides thereof to form a cylindrical surface facing the outside of the first closed path 011, defining a cylindrical surface for forming a concrete well hole.

In this embodiment, the structures of the stressed form 100 and the connection form 200 are the most common structures, i.e., channel steel and angle steel. The channel steel can be formed by blanking and bending two sides, the angle steel can be formed by blanking and bending at one time, and the angle steel are connected by welding and screws. Therefore, the cast-in-place concrete column and borehole combined mold 003 in this embodiment has the most prominent advantages of simple processing, and extremely high economy and practicability, in addition to the advantages of the combined mold described in the first embodiment or the second embodiment.
