Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated exterior wall panels, in particular to a template structure for prefabricated concrete exterior wall panels. Background Art

[0002] Reinforced concrete plate-type components processed in prefabrication plants or construction sites for building assembly are referred to as wall panels or sidings. The use of prefabricated concrete wall panels to build assembled large-panel buildings can improve the degree of factory and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal influences, shorten the construction period, and are divided into two categories according to their functions: interior wall panels and exterior wall panels.

[0003] The frame of the existing prefabricated exterior wall panel is composed of multiple templates, but when installing the template, the template is only connected together by a simple connection method, and the position of the module is restricted by magnetic boxes on both sides. However, during long-term use, the template will be subjected to the pressure and force of concrete, resulting in deformation of the template and thus making the structure of the poured concrete prefabricated exterior wall panel unstable, affecting the building quality. Therefore, a template structure for concrete prefabricated exterior wall panels is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the embodiment, Figure 1-5 A template structure for a prefabricated concrete exterior wall panel is provided. The utility model comprises a template platform 1. Two supporting devices 2 are fixedly installed on the top of the template platform 1 by fasteners and are symmetrically distributed on the left and right. Two first modules 3 are arranged on the top of the template platform 1 and are symmetrically distributed on the left and right. Second modules 4 are fixedly installed on the rear sides of the two first modules 3 by fasteners. Third modules 5 are fixedly installed on the front sides of the two first modules 3 by fasteners.

[0026] The supporting device 2 includes a supporting block 201, a connecting rod 202, a moving block 203, a supporting rod 204, and a docking plate 205. An installation groove 206 is opened inside the supporting block 201, and the connecting rod 202 is fixedly installed inside the installation groove 206. The moving block 203 is slidably connected to the outer side of the connecting rod 202. The supporting rod 204 is rotatably connected to a side of the moving block 203 close to the first module 3, and the other side of the supporting rod 204 is rotatably connected to a side of the docking plate 205 away from the first module 3.

[0027] As a preference of this embodiment, a rubber buffer pad 6 is fixedly installed inside the installation groove 206 , and one end of the rubber buffer pad 6 is in contact with a side of the moving block 203 away from the first module 3 .

[0028] When pouring concrete, outward pressure is generated inside. The docking plate 205, the support rod 204 and the docking plate 205 ensure that the position of the first module 3 does not change, and the transmitted force is absorbed. The rubber buffer pad 6 can further absorb the impact force to ensure the stability of the first module 3 during use.

[0029] As a preference of this embodiment, an auxiliary block 7 is fixedly installed between the moving block 203 and the docking plate 205 .

[0030] The butt joint plate 205 and the support rod 204 form a triangle shape, thereby improving the stability of the support.

[0031] As a preference of this embodiment, sealing strips 8 are bonded to the bottoms of the first module 3 , the second module 4 and the third module 5 .

[0032] Avoid uneven surface of formwork table 1 causing concrete slurry to flow out of the module, affecting the normal use of bolts and magnetic boxes.

[0033] As a preference of this embodiment, the number of the moving blocks 203 is three and they are evenly distributed on the outside of the connecting rod 202 .

[0034] Strengthen the supporting effect of the first module 3.

[0035] As a preference of this embodiment, the outer sides of the two first modules 3 are each provided with a plurality of evenly distributed through slots 9 , and the center point of the docking plate 205 is located corresponding to the center point position between two adjacent through slots 9 directly opposite to each other.

[0036] The midpoint between the two nearest through-slots 9 on the side of the docking plate 205 facing the first module 3 coincides with the midpoint of the docking plate 205, so that when the docking plate 205 is in effect, it will not affect the steel bars that need to extend to the outside of the module, ensuring that when it plays a supporting role, the steel bars can be smoothly pulled out of the module.

[0037] Working principle: The first module 3, the second module 4 and the third module 5 are connected together by fasteners, and then the support device 2 is installed. When installing, the support block 201 only needs to be fixed to the mold platform 1 through the front and rear sides. It is placed in the middle of the mold platform 1 and fixed, leaving a hole, which makes it inconvenient to plan later.

[0038] In addition, the triangular support stabilizing shape formed by the support rod 204, the docking plate 205 and the auxiliary block 7 strengthens the support effect on the first module 3, and the rubber buffer pad 6 further absorbs the impact force to ensure the position of the first module 3 during use. Grooves for steel bars to pass through are reserved inside the first module 3 and the third module 5. After the steel bars are installed, the grooves through which the steel bars pass need to be sealed by sealing blocks to ensure that the quality of the precast concrete exterior wall panels cast in the mold cavity formed by the first module 3, the second module 4, and the third module 5 is better.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
