Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, and in particular to a reusable building formwork. Background Technology

[0002] Formwork is an auxiliary tool used during wall pouring to fix, support, and constrain the shape of concrete. Most existing formwork is custom-made, designed according to the specific wall to be poured, and then assembled and installed on-site. One existing wall pouring formwork includes two panels and two frames. The two frames are installed on opposite sides of the two panels, and the two panels are connected by multiple tie bolts.

[0003] However, existing templates require customization, needing to be designed specifically for the wall and assembled on-site. This prevents them from being reused for different construction scenarios and makes them inconvenient to disassemble after casting. Utility Model Content

[0004] The purpose of this invention is to provide a reusable building template, which solves the problem that conventional templates need to be customized and cannot be reused according to different construction scenarios.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides a reusable building template, including multiple spliced ​​bottom single templates and multi-layer upper single templates assembled on the bottom single templates;

[0007] The outer wall of the bottom unit template is symmetrically provided with a third plug-in seat and a fourth plug-in seat. Two adjacent bottom unit templates are spliced ​​together by the third plug-in seat and the fourth plug-in seat to form a lower split snap-fit ​​seat. The outer wall of the upper unit template is provided with a plug-in plate for inserting into the lower split snap-fit ​​seat.

[0008] On the side wall of the upper single-unit template, there are a first plug-in seat and a second plug-in seat that are adapted to and plug into the plug-in plate of the upper single-unit template. The first plug-in seat and the second plug-in seat are symmetrically arranged about the plug-in plate.

[0009] The building formwork located on both sides of the reinforcing cage is locked together by connecting rods and locking nuts. Pre-drilled holes adapted to the connecting rods are provided on both the bottom single formwork and the upper single formwork.

[0010] Furthermore, a first connector and a first connector groove are respectively provided on both ends of the upper single-unit template to splice with the adjacent upper single-unit template.

[0011] Furthermore, the first insertion slot is a dovetail-shaped slot, and the first insertion connector is an insertion rib adapted to the dovetail-shaped slot.

[0012] Furthermore, the second connector and the first connector on the adjacent upper single-unit template form an upper split snap-fit ​​connector; the connector plate on the upper single-unit template is adapted to be inserted into the upper split snap-fit ​​connector.

[0013] Furthermore, both the first and second sockets are provided with dovetail-shaped slots, and the socket plate is a dovetail-shaped socket plate adapted to them.

[0014] Furthermore, dovetail-shaped slots are provided in both the third and fourth connectors.

[0015] Furthermore, a sleeve is fitted onto the connecting rod, one end of the connecting rod is provided with a nut, and the other end is provided with a thread adapted to the locking nut, the locking nut being a wing nut.

[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0017] The bottom and top individual formwork of this invention can be available in multiple sizes and specifications, and can be assembled according to the scenario. They can be reused multiple times, reducing formwork wear and construction costs. Furthermore, the interlocking joints and plates of the bottom and top individual formwork enable rapid assembly. The symmetrical interlocking structure between adjacent formwork also facilitates disassembly after pouring. Attached Figure Description

[0023] refer to Figure 1 This embodiment discloses a reusable building template, including multiple spliced ​​bottom single templates 7 and multi-layer upper single templates 1 assembled on the bottom single templates 7.

[0024] In use, the building formwork located on both sides of the reinforcing cage 6 is locked together by connecting rods 3 and locking nuts 5. Pre-drilled holes adapted to the connecting rods 3 are provided on both the bottom single formwork 7 and the upper single formwork 1. A sleeve 4 is fitted onto the connecting rod 3. A nut is installed at one end of the connecting rod 3, and a thread adapted to the locking nut 5 is provided at the other end. The locking nut 5 is a wing nut. The connecting rods 3 and locking nuts 5 are used to connect two parallel bottom single formwork 7 layers and two parallel upper single formwork 1 layers, respectively. In specific implementation, the sleeve 4 can be a PVC or PE pipe, which facilitates the disassembly of the bottom single formwork 7 and the upper single formwork 1.

[0025] During disassembly, the connecting rod 3 is loosened by loosening the wing nut 5, and the plug plates 13 of each layer are pulled out from top to bottom in sequence to disassemble the template by peeling.

[0026] The bottom single-unit template 7 and the top single-unit template 1 are both made of lightweight materials, such as aluminum alloy.

[0027] Referring to 1 and 2, a third insertion seat 81 and a fourth insertion seat 82 are symmetrically installed on the outer wall of the bottom unit template 7. Two adjacent bottom unit templates 7 are spliced ​​together by the third insertion seat 81 and the fourth insertion seat 82 to form a lower split snap-fit ​​seat. An insertion plate 13 is installed on the outer wall of the upper unit template 1 to insert into the lower split snap-fit ​​seat. The insertion plate 13 on the upper unit template 1 is used to snap into the lower split snap-fit ​​seat in a latching manner, thereby snapping and limiting the two adjacent bottom unit templates 7.

[0028] In another embodiment, dovetail-shaped slots are provided in both the third connector 81 and the fourth connector 82, and the lower split connector is locked and connected by the dovetail-shaped connector plate 13.

[0029] In this embodiment, a first insertion seat 21 and a second insertion seat 22, adapted to and inserted into the insertion plate 13 of the upper single-unit template 1, are fixedly installed on the side wall of the upper single-unit template 1. The first insertion seat 21 and the second insertion seat 22 are symmetrically designed with respect to the insertion plate 13. The second insertion seat 22 and the first insertion seat 21 on the adjacent upper single-unit template 1 form an upper split snap-fit ​​seat; the insertion plate 13 on the upper single-unit template 1 is adapted to be inserted into the upper split snap-fit ​​seat.

[0030] The splicing method between different layers of the upper single-unit template 1:

[0031] The upper single-unit template 1 of the upper layer is inserted into the upper split snap-fit ​​seat of the lower layer, thereby realizing the splicing and locking of the two spliced ​​upper single-unit templates 1 of the lower layer by using the upper single-unit template 1 of the upper layer.

[0032] refer to Figure 1 and Figure 2 In specific implementation, dovetail-shaped slots are provided in both the first plug-in 21 and the second plug-in 22, and the plug-in plate 13 is a dovetail-shaped plug-in plate adapted to them; wherein the dovetail-shaped design of the plug-in plate 13 not only achieves lateral limitation between the first plug-in 21 and the second plug-in 22, but also longitudinal limitation.

[0033] refer to Figure 1 In this embodiment, a first connector 11 and a first connector slot 12 are respectively provided on both ends of the upper single-unit template 1 to splice with the adjacent upper single-unit template 1. The first connector slot 12 is a dovetail-shaped slot, and the first connector 11 is a connector rib adapted to the dovetail-shaped slot; used to realize the connection between the ends of adjacent upper single-unit templates 1.

[0034] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
