[0001] This utility model relates to the field of prefabricated building construction technology, and more specifically, to a connectable template, template unit and template system for prefabricated walls. Background Technology

[0002] In the existing technology, the ordinary plastic formwork currently used is an integral structure with a long length, which makes it very inconvenient to transport and construct, and it is prone to grout leakage at the contact surface with the precast wall panel.

[0003] Different buildings have different floor heights. The use of an integral structure for the formwork will require customized processing for walls of different heights, which will greatly increase construction costs.

[0004] In addition, conventional plastic formwork in existing technologies requires on-site drilling to allow for concrete pouring, which is extremely inconvenient. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a connectable template, template unit and template system for prefabricated walls. Through the cooperation of template one and template two, the connectable template can be adjusted arbitrarily according to the use requirements to meet the construction requirements of walls of different heights. At the same time, the shortening of the template will facilitate transportation and make construction more flexible.

[0006] The solution adopted by this utility model to solve the technical problem is:

[0009] A mating groove is provided at one end of the template one near the template two, and a mating protrusion is provided at one end of the template two near the template one to cooperate with the mating groove.

[0010] In some possible implementations, to facilitate subsequent pouring construction, a pouring hole is provided through the template one or template two; and a pouring head that communicates with and is detachably connected to the pouring hole is also included.

[0012] In some possible implementations, in order to make template one and template two universal, a mating protrusion is provided at the end of template one away from the mating groove, and a mating groove is provided at the end of template two away from the mating protrusion.

[0013] In some possible implementations, in order to effectively achieve the mating groove and the mating protrusion; the mating groove has a T-shaped structure with an opening at its small end; the mating protrusion has a T-shaped structure.

[0014] In order to effectively achieve the mating of the mating groove and the mating protrusion, the mating groove has a dovetail structure with an opening at its small end; the mating protrusion also has a dovetail structure.

[0015] In some possible implementations, template one and template two have the same structure, including a casting surface and an assembly surface arranged opposite to each other; the mating groove is arranged on the assembly surface; after template one and template two are connected, the two sets of casting surfaces are coplanar.

[0016] In some possible implementations, to prevent grout leakage during the pouring process, a bonding area matching the precast wall panel and a pouring area for the pouring medium are provided on the pouring surface, and a grout-stopping structure with elastic deformation is provided on the bonding area and along its length; the grout-stopping structure is located between the bonding area and the pouring surface.

[0017] In some possible implementations, in order to ensure that template one and template two have good rigidity and prevent deformation during pouring, several sets of reinforcing ribs are provided on the assembly surface, and the sets of reinforcing ribs are arranged in an alternating manner. Several sets of tie holes are respectively provided through template one and template two.

[0018] on the other hand:

[0019] This utility model provides a template unit for prefabricated walls, including two sets of interlocking templates as described above, and tie rods for connecting and fixing the two sets of interlocking templates, the two sets of interlocking templates being arranged opposite to each other.

[0022] At least one set of mating templates in a set of template components is provided with a pouring head.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] The interlocking template in this utility model can be adjusted arbitrarily according to the usage requirements by cooperating with template one and template two, so as to meet the construction requirements of walls of different heights. At the same time, the shortened template will facilitate transportation and make construction more flexible.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The present invention will now be described in detail.

[0037] on the one hand:

[0038] like Figures 1-7 As shown:

[0039] This utility model discloses a connectable template for prefabricated walls, including template 1 and template 2 that connects with one end of template 1. Specifically, templates 1 and 2 are made of plastic, allowing them to separate from the pouring medium without the need for a release agent, effectively improving construction efficiency. A connecting groove 11 is provided at the end of template 1 near template 2, and a connecting protrusion 21 that engages with the connecting groove 11 is provided at the end of template 2 near template 1. After the templates 1 and 2 are connected, they form an integral structure. Compared with the integral structure in the prior art, this design shortens the overall length of the template, facilitating construction and transportation, and allows for free combination according to the height of the wall, meeting the construction needs of walls of different heights. It eliminates the need for customization based on different wall heights, significantly reducing construction costs.

[0040] Template 1 and Template 2 come in various lengths. When Template 1 and Template 2 of different lengths are joined together, they can meet the height requirements of walls of different heights. During construction, the construction workers select Template 1 and Template 2 of the appropriate length according to the wall height and join them together so that the length of the joined templates matches the wall height.

[0041] Furthermore, such as Figure 2As shown, template 1 and template 2 have the same structure, including a casting surface 102 and an assembly surface 103 arranged opposite to each other; the mating groove 11 is provided on the assembly surface 103; after template 1 and template 2 are connected, the two sets of casting surfaces 102 are coplanar.

[0042] To prevent grout leakage during the pouring process, a bonding area matching the precast wall panel 5 and a pouring area for pouring medium are provided on the pouring surface 102. A grout-stopping structure 4 with elastic deformation is provided on the bonding area and along its length. The grout-stopping structure 4 is located between the bonding area and the pouring surface 102.

[0043] Specifically, the bonding area and the pouring area are on the same plane, and the bonding area consists of two sets set on both sides of the pouring area; the bonding area is mainly used to fit with the precast wall panel 5, and after pouring, the bonding area will close the pouring cavity formed by the two adjacent sets of precast wall panels 5.

[0044] The grout-stopping structure 4 includes an installation groove 1021 set on the joint area and arranged along the length of the joint area, and a grout-stopping strip installed in the installation groove 1021; the side of the grout-stopping strip away from the bottom of the installation groove 1021 is located on the outside of the installation groove 1021; after the templates (template 1 and template 2) are installed, the grout-stopping strip will come into contact with the outer side of the precast wall panel 5, and under the applied pressure, it will produce elastic deformation, changing the hard contact between template 1, template 2 and the precast wall panel 5 into a soft contact, thereby achieving effective sealing of the joint area.

[0045] Furthermore, the grout-stopping strip is made of rubber; of course, the grout-stopping strip can also be made of other elastically deformable materials.

[0046] In some possible implementations, in order to facilitate the later pouring construction, a pouring hole 101 is provided through the template 1 or template 2; the pouring hole 101 will penetrate the assembly and pouring surface 102, and the setting of the pouring hole 101 eliminates the need to make additional holes during on-site construction, thus speeding up the construction efficiency.

[0047] During actual construction, depending on the actual conditions of the construction site, template 1 or template 2 with pouring holes 101 can be selected and installed together with another set of templates (template 2 or template 1) to achieve pouring and speed up construction efficiency; for other locations, templates without pouring holes 101 (template 1 or template 2) can be used in conjunction.

[0048] In some possible implementations, a pouring head 3 is also included that is connected to and detachably connected to the pouring hole 101. The pouring head 3 is connected to the delivery pipe on the pouring equipment to realize the pouring construction.

[0049] In some possible implementations, such as Figure 3, Figure 4 , Figure 5 As shown, the pouring head 3 includes an assembly base 31 installed on template 1 or template 2 and having a through hole, and a pipe joint 32 installed on the assembly base 31 and communicating with the through hole; the through hole is communicating with the pouring hole 101.

[0050] The mounting base 31 is detachably mounted on the mounting surface 103, and can be connected to the template 1 or template 2 by bolts; the pipe joint 32, through hole, and pouring hole 101 allow the pouring medium to enter the pouring cavity.

[0051] Specifically, the pipe joint 32 and the mounting base 31 are connected in a detachable manner, such as by a threaded connection.

[0052] Furthermore, the mounting base 31 includes a base 311 that is detachably connected to the mounting surface 103 and has a through hole, and a mounting part 312 that is mounted on the base 311 and communicates with the through hole. The base 311 is provided with a mounting hole, and the bolt, the mounting hole, and the screw hole on the mounting surface 103 cooperate to realize the connection between the base 311 and the mounting surface 103.

[0053] The assembly part 312 is sleeve-shaped, with an internal thread inside the sleeve and an external thread that mates with the internal thread on the outside of the pipe joint 32.

[0054] The pipe fitting 32 includes an assembly head 321 with external threads and a connecting pipe portion 322 that is connected to the assembly head 321 and integrally formed.

[0055] The connection is detachable and can be disassembled after the casting is completed, making it easy to clean the mounting base 31 and the pipe joint 32.

[0056] In some possible implementations, in order to make template 1 and template 2 universal, a mating protrusion 21 is provided at the end of template 1 away from the mating groove 11, and a mating groove 11 is provided at the end of template 2 away from the mating protrusion 21.

[0057] With this configuration, both template 1 and template 2 have butt joint protrusions 21 and butt joint grooves 11. In use, since template 1 and template 2 have the same structure, it is not necessary to consider their installation positions. They can be directly combined, ensuring that one set of butt joint protrusions 21 is located on the outside of the upper beam of the pouring cavity, which greatly improves construction efficiency.

[0058] Furthermore, the side of the mating protrusion 21 closest to the casting surface 102 is not coplanar with the casting surface 102, and the distance between the side of the mating protrusion 21 closest to the casting surface 102 and the assembly surface 103 is less than the distance between the casting surface 102 and the assembly surface 103. This arrangement ensures that the mating protrusion 21 is located on the outside of the upper beam of the casting cavity.

[0059] In some possible implementations, in order to effectively achieve the engagement of the mating groove 11 and the mating protrusion 21 and effectively prevent the two from separating; the mating groove 11 has a T-shaped structure with an opening at its small end; the mating protrusion 21 has a T-shaped structure, and the small end of the mating protrusion 21 is connected to the template 1 or the template 2.

[0060] In some other embodiments, the mating groove 11 has a dovetail structure with an opening at its small end; the mating protrusion 21 has a dovetail structure, and the small end of the mating protrusion 21 is connected to the template 1 or the template 2.

[0061] The smaller end of the mating groove 11 is located near the other set of template 1 or template 2;

[0062] During installation, such as Figure 6 As shown, the mating protrusion 21 is inserted into the mating groove 11 from the outside of the assembly surface 103 to connect the template 1 and the template 2. After the connection, the pouring surface 102 of the template 1 and the pouring surface of the template 2 are coplanar, that is, on the same plane; so that the outer surface of the pouring medium is coplanar with the outer surface of the precast wall panel after the pouring is completed.

[0063] In some possible implementations, in order to ensure that template 1 and template 2 have good rigidity and prevent deformation during pouring, several sets of reinforcing ribs are provided on the assembly surface 103. The sets of reinforcing ribs are arranged in an alternating manner. By providing reinforcing ribs, the bending and shear resistance of template 1 and template 2 can be effectively improved.

[0064] Several sets of tie holes 104 are respectively provided through template 1 and template 2; the tie holes 104 are located at the intersection of the secondary ribs.

[0065] on the other hand:

[0066] This utility model provides a template unit for prefabricated walls, which is used in conjunction with precast wall panels to close the casting cavity formed by the precast wall panels 5; it includes two sets of interlocking templates as described above, and tie rods 6 for connecting and fixing the two sets of interlocking templates; the two sets of interlocking templates are arranged opposite to each other.

[0067] The two sets of mating templates are arranged in a one-to-one correspondence with each other. The two sets of mating templates are connected and fixed together by tie rods 6 to form a whole, which closes the casting cavity formed between the two sets of precast wall panels. The casting holes can be set in multiple sets along the length of template 1 or template 2, and used in conjunction with multiple sets of tie rods 6.

[0068] on the other hand:

[0069] This utility model provides a template system for prefabricated walls, including multiple sets of prefabricated wall panels and template components used in conjunction with the multiple sets of prefabricated wall panels 5 as described above; the prefabricated wall panels 5 are fixed to the mounting base surface by mounting components; each template component is located between two adjacent sets of prefabricated wall panels 5 and is used to close the casting cavity formed by the two adjacent sets of prefabricated wall panels 5;

[0070] Among them, at least one set of mating templates in a set of template components is equipped with a pouring head 3. Specifically, the location of the pouring pipe in the pouring equipment at the construction site can be determined.

[0071] After the precast wall panel 5 is installed, a casting cavity will be formed between two adjacent sets of precast wall panels. The casting cavity will be sealed by two sets of oppositely arranged mating templates that abut against the outer side of the precast wall panel 5.

[0072] During pouring, the pouring pipe of the pouring equipment is connected to the dockable template with the pouring head 3, and then pouring is carried out; after pouring is completed, the dockable template can be removed by removing the tie rod 6, and the dockable template can be reused after removal.

[0073] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
