On the other hand, a large number of templates and support columns used in the existing concrete floor slab are formed by temporarily sawing and cutting templates and columns with different lengths by using tools according to site requirements and then nailing with hammers, iron nails and 'mouth' -shaped nails before pouring cement; after the concrete forming process is finished, the iron nails are pulled out and the templates and the support columns are disassembled, so that the disassembly and the transportation workload is high, the labor intensity is high, the templates and the support columns are seriously damaged after being forcibly disassembled, and the recycling rate is low. Meanwhile, in the prior construction, after the reinforced concrete is poured, the template and the adjustable support are required to be removed until the strength of the reinforced concrete reaches 100%, and the concrete is usually maintained for 28 days, namely the shortest turnover period of the template and the support member is 28 days, so that the construction period is further prolonged; and the traditional template is made of steel with heavier texture, so that the template is difficult to carry. Later, some solutions are provided in the patents named as 'concrete floor slab mold' in patent publication number CN2234476Y 'and' double-disassembly type formwork support operation platform frame 'in patent publication number CN 2594381Y', which have the effect of simplifying certain procedures, but the original installation structure of the support column is not adopted, so that the whole construction system still depends on the support column, and the bulkiness of the structure and the complicated disassembly and even the inconvenience of reciprocating transportation caused by the bulkiness are still the technical problems which cannot be solved at present. Finally, when the construction period is calculated, not only the time for installing and removing the templates, but also the time for decorating the interior wallboard or the floor slab are considered, and the corresponding construction period is occupied; meanwhile, with the increasing aesthetic standard of people, the requirements for interior decoration are also increasing. Therefore, a solution is needed.

The supporting effect of the transverse rod is matched, so that the disassembling-free template is formed by combining smaller sub-templates, and the position stabilizing effect of the disassembling-free template can be ensured. On the other hand, the disassembly-free template has a decoration function. Because the gap is less after the mortise and tenon joint is installed, therefore, the sub-templates can be directly arranged with various decorations and the like at the lower plate surface of the sub-templates during construction without disassembly and replacement, the integral time from the construction of the concrete structure main body to the decoration can be effectively reduced, even the decorations on the sub-templates can be replaced according to the requirements of owners, the patterns are changeable, and the use is very flexible.

9) In actual design, the utility model can be in a plurality of sets of matching structures, for example, when more than three sub-templates are adopted, two sub-templates at two ends are A bodies, a sub-template in the middle group is B body, and at the moment, the A body needs to be lapped with a connecting block, so that the corresponding lapping end is a normal straight edge; and the two ends of the B body are matched with the corresponding A body, so that the two ends are provided with mortise and tenon connecting parts. The adjacent ends are spliced with each other, and at the moment, the mortise and tenon joint part at the A body and the mortise and tenon joint parts at the two ends of the B body form a complementary design mode, so that the two parts can be spliced with each other; when the utility model is produced, only the submodules of two types are required to be manufactured, and the submodules are matched with each other in a building block mode to form the whole construction surface, so that the utility model is very convenient to use. Of course, the body A can be adopted simply, and the quick pouring process of the wallboard can be realized by utilizing the mutual engagement of the adjacent surfaces of the body A and the lap joint function of the straight edges, and attention is paid to the fact that the mortise-tenon joint parts of the adjacent ends of the body A are of complementary structures.

10 The upwarp single teeth and the slope-shaped matching surface are combined to form a concave surface connecting part and a convex surface connecting part, and the upwarp single teeth are mutually staggered, so that a complementary design mode is realized. In addition, the cooperation of concave surface connecting portion and convex surface connecting portion can further reduce the installation back gap between them to make the installation gap of looking up the visual angle present a word form, ensured the neatly degree of the lower face of submodule board, main structure visual influence can further reduce, more is favorable to showing the wholeness of decorative face department pattern.

In operation, as shown in fig. 3, adjacent sub-modules 31 are connected to form the configuration shown in fig. 1, 7 and 9 by means of transverse connecting pins 34 extending through mounting holes 33 in the interlocking mortise and tenon joints 32.

For the sub-templates 31, there are two configurations for them, i.e. the construction face may be formed by more than two sub-templates 31 spliced end to end with each other by means of adjacent ends. The method comprises the following steps:

when only two sub-templates 31 are used, both sub-templates 31 are a-bodies, i.e., the state shown in fig. 6; at this time, the body a needs to be overlapped with the connecting block 12, so that the corresponding overlapped end should be a normal straight edge; after assembly, it can be snapped onto two adjacent support assemblies as shown in FIGS. 1-4. The adjacent ends of the A body are matched by the mortise and tenon joint parts 32 to achieve the complementary type inserting and connecting purpose, so that the use is very convenient.

When more than three sub-templates 31 are adopted, the sub-templates 31 with the mortise and tenon joint parts 32 arranged on the single end are A bodies, and the sub-templates with the mortise and tenon joint parts 32 arranged on the two ends of the middle group are B bodies; that is, at this time, the body a needs to be overlapped with the connecting block 12, so that the corresponding overlapped end should be a normal straight edge, and the structure is shown in fig. 6; and the two ends of the B body are matched with the corresponding A body, so that the two ends are provided with mortise and tenon joint parts 32, and the structure is shown in fig. 8. The adjacent ends are spliced with each other, at the moment, the mortise and tenon joint part 32 at the A body and the mortise and tenon joint parts 32 at the two ends of the B body form a complementary design mode, and the two parts can be spliced with each other to form a structure shown in figure 9; this makes the utility model only need to make the submodule 31 of two types during production, and the follow-up cooperation forms whole construction face through the building block mode each other, and it is very convenient to use equally.

Regardless of the manner of mating described above, mortise and tenon joint 32 includes corresponding male and female joints. As can be seen from fig. 1-2, the female and male connection portions are complementary. Meanwhile, in actual design, as shown in fig. 6 and 8, the upwarp single teeth 32a and the slope-shaped matching surface 32b are combined to form a concave connection part and a convex connection part, and the upwarp single teeth 32a of the two are staggered or staggered with each other, so that a complementary design mode is realized, and a straight installation gap as shown in fig. 7 and 9 is formed in a bottom view. The mounting hole 33 is coaxially penetrated through the corresponding single tooth at the same end, and finally the transverse connection effect as shown in fig. 3 is realized.

The decorative layer can be in different forms according to the requirements of users. Meanwhile, the sub-templates 31 are hollow, the middle part is provided with a heat insulation hole cavity 36, and the air in the middle can play a role in heat insulation.

As for the upper protrusion 35, as shown in fig. 3-4 and fig. 6 and 8, the upper protrusion 35 is a T-shaped protrusion for further enhancing the engagement of the sub-template 31 with the structure, making the sub-template 31 more secure during use.

2. Support assembly

As can be seen from fig. 1-2 and 4, the support assembly of the present utility model includes a support beam 20 and a lap joint portion disposed on the support beam 20. The structure of the lap joint part is shown with reference to fig. 1 and 4-5, and comprises a connecting block 12, a U-shaped clamping connection rod 11 and a nut 13. During installation, the clamping connection rod 11 is clamped into the supporting beam 20 as shown in fig. 4, and an integral part is formed by means of threaded matching of the connecting block 12 and the vertical rod section 11a of the clamping connection rod 11, and finally an anchor point system for overlapping the overlapping ends of the disassembly-free templates is formed.

1-4 are only one example of an implementation configuration, since the concrete filled steel tube beam as the support beam 20 is a structural member, it is not disassembled; so that later removal alone is only required by removing the semicircular members, i.e. the connection blocks 12. On the one hand, on the other hand, as shown in fig. 1-5, the clamping groove 12a can be arranged on the connecting block 12, so that the transverse rod 40 is clamped through the clamping groove 12a, and further, the transverse rod 40 is utilized to form a grid type supporting structure, the supporting reliability and the supporting quality of the grid type supporting structure are further improved, and the weight of the wall body during the disassembly-free template and the floor pouring of the lower part of the floor slab can be effectively supported. On the other hand, when the top end surface of the connecting block 12 is lower than the beam top surface of the supporting beam 20, the top end surface of the connecting block 12 forms a matching surface for overlapping the overlapping end; during installation, the clamping connection rod 11 is attached to one side of the supporting beam 20 as far as possible, so that the installation interference between the lap joint end of the disassembly-free template and the clamping connection rod 11 is reduced.

Of course, in actual design, a matching groove may be concavely formed at the overlapping end of the sub-die 31, so that the overlapping end is clamped into the clamping rod 11 to indirectly avoid the clamping rod 11. The height of the top end surface of the connecting block 12 can be as same as that of the beam top surface of the flush supporting beam 20 shown in fig. 3-4, and the avoiding type mounting purpose of the overlap end of the disassembly-free template and the clamping rod 11 can be realized by a mode of concavely arranging a matching groove at the overlap end in advance.

In actual construction, the support assembly is erected firstly, then the disassembly-free template is paved above, the hooking and fixedly connecting effects of the adjacent sub-templates 31 are guaranteed, the mortise and tenon joint parts 32 are mutually and complementarily penetrated, then the transverse connecting pin bolts 34 are used for fixing, and finally the whole construction surface is formed, so that the expansion effect of concrete in the curing process can be effectively resisted, the gaps at the subsequent joints are smaller, and the visual requirement of a main structure is met. And finally, pouring concrete directly above the construction surface, and forming the floor slab structure with stable quality after the concrete is solidified.
