Description

Technical Field

[0001] This utility model relates to the field of building formwork, and in particular to a building formwork device that is easy to install. Background Technology

[0002] Construction formwork is a device used to assist in the production process of concrete pouring, and is used to ensure the correct structure, position and size of the concrete. According to the search, Chinese patent with publication number CN222333258U discloses a construction plastic formwork wall device that is easy to assemble, including formwork, support frame, detachable layer, connecting block one, connecting groove one, connecting block two, connecting groove two, limiting block and material mechanism. The connecting block and the limiting block cooperate to fix two adjacent formwork pieces.

[0003] While this template facilitates construction, the simple positioning and fixing of the connecting blocks and limiting blocks presents problems such as grout leakage at the joints and easy loosening. Utility Model Content

[0004] The purpose of this utility model is to provide a convenient building formwork device to solve the above-mentioned problems, and to solve the problems of grout leakage at joints and easy loosening of existing building formwork.

[0005] To address the aforementioned problems, this utility model provides a technical solution: a building formwork device that is easy to install, comprising a panel and a fixing plate.

[0006] On the panel, the surface in direct contact with the concrete is the concrete contact surface, and opposite the concrete contact surface is the grid structure surface; the grid structure surface has several longitudinal and transverse reinforcing ribs that are evenly distributed in a cross pattern, and the longitudinal and transverse reinforcing ribs together form an array of regularly arranged installation grids on the grid structure surface.

[0007] The panel has interconnected narrow grooves on all four sides, in which a continuous sealing rubber strip is detachably and fixedly installed. The width of the sealing rubber strip is the same as the thickness of the mounting plate, and the cross-section is T-shaped.

[0008] On the fixing plate, the surface that is in direct contact with the panel is a protrusion structure surface. Several fixing protrusions are arranged in an array on the protrusion structure surface. The distribution of the fixing protrusions corresponds to the distribution of the installation grid on the panel, and the fixing protrusions and the installation grid can be matched and fixedly installed.

[0009] On the fixing plate, opposite to the protrusion structure surface is the overall fixing surface, which has several reinforcing strips evenly distributed longitudinally and laterally.

[0010] Furthermore, the fixing protrusions on the fixing plate are frustum-shaped.

[0011] Furthermore, the mounting grid on the panel is square, hexagonal, or circular.

[0012] Furthermore, the panel contains curved or zigzag-shaped sections.

[0013] Furthermore, the building formwork is made of one or more of the following materials: polyvinyl chloride, polypropylene, polycarbonate, and high-density polyethylene.

[0014] Furthermore, the concrete contact surface can be a smooth plane or a corresponding raised or recessed pattern, depending on the surface requirements of the concrete component to be poured.

[0015] Compared with existing technologies, the significant advantages of this invention are:

[0016] Firstly, when splicing adjacent panels, the sealing rubber strips on the panels fit together to fully fill the gaps and prevent concrete leakage.

[0017] Secondly, during construction, the fixing plates secure adjacent panels from top to bottom to ensure the stability of the entire formwork system.

[0018] Thirdly, the building formwork provided by this utility model can directly produce matching panels and fixing plates in the factory according to the building construction drawings. At the construction site, the panels can be directly spliced ​​and fixed with fixing plates. It can be spliced ​​and extended as needed in the longitudinal and transverse directions, which can adapt to the pouring of concrete components of beams, columns and walls of different sizes, avoiding the trouble of processing on the construction site. Compared with concrete formwork that is cut and processed on site, it can shorten the construction period and better complete the special shape design of the building. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figure 1 As shown, a building formwork device that is easy to install includes a panel 1 and a fixing plate 2.

[0035] like Figures 1 to 7 On panel 1 shown, the surface in direct contact with the concrete is concrete contact surface 15. Concrete contact surface 15 can be a smooth and flat plane, or a pattern corresponding to the pattern on the outer surface of the concrete (such as a brick-laying pattern). In this way, the surface treatment of the concrete can be completed with only a little processing after the concrete is poured.

[0036] On panel 1, the surface opposite to the concrete contact surface 15 is a grid structure surface 16. The grid structure surface 16 has several longitudinal and transverse reinforcing ribs 11. The longitudinal reinforcing ribs 11 and the transverse reinforcing ribs 11 together form the installation grid 14. The installation grid 14 can be a square, a regular hexagon, or a circle, etc.

[0037] like Figures 1 to 5 As shown, a continuous narrow groove 12 is cut around the perimeter of panel 1, and the narrow groove 12 completely surrounds the entire side of panel 1. A T-shaped sealing rubber strip 13 is detachably and fixedly installed in the narrow groove 12, and the corresponding T-shaped sealing rubber strip 13 completely surrounds the entire side of panel 1. The sealing rubber strip 13 of each panel 1 is a closed ring, and the side width is the same as the thickness of panel 1. In addition, the sealing rubber strip 13 is relatively thin. When adjacent panels 1 are spliced ​​around the perimeter or side, the T-shaped sealing rubber strip 13 can fill the gap between panels 1, preventing grout leakage during pouring. After multiple uses of the building formwork of this utility model, the damaged or aged sealing rubber strip 13 can be replaced to maintain the overall tightness of the building formwork.

[0038] like Figures 6 to 7 The diagram shown is a schematic diagram of the overall structure of two other embodiments of the panel 1 provided by this utility model.

[0039] To match the building's shape, panel 1 can be at a certain angle or with a certain curvature. Such irregularly shaped templates can be directly processed and produced in the factory, which can meet the building design requirements while shortening the construction cycle.

[0040] like Figure 1 , Figures 8 to 11 The fixed plate 2 shown has a protrusion structure surface 23 that is in contact with and fixed to the mesh structure surface 16 of the panel 1. The protrusion structure surface 23 has fixed protrusions 21 arranged in a longitudinal and transverse array. The fixed protrusions 21 are generally frustum-shaped and their specific distribution corresponds to the installation mesh 14.

[0041] The diameter of the fixing protrusion 21 is smaller on the outside and larger on the inside. That is, the diameter of the upper circular surface of the fixing protrusion 21 is the smallest, and the diameter of the fixing protrusion 21 is larger the closer it is to the overall fixing surface 24. Such a frustum-shaped fixing protrusion 21 can be inserted into the installation grid 14 like a wedge, so that the fixing plate 2 can firmly fix the panel 1.

[0042] On the fixed plate 2, opposite to the protrusion structure surface 23 is the overall fixed surface 24. The overall fixed surface 24 has several horizontal and vertical reinforcing strips 22. The reinforcing strips 22 enhance the strength of the fixed plate 2 and increase the friction between the overall fixed surface 24 and the formwork support scaffold, preventing relative swaying and ensuring the stability of the entire building formwork.

[0043] In use, the panels 1 are spliced ​​to adapt to the size requirements of different buildings; different panels 1 are directly connected and fixed through the fixing plate 2; concrete is directly poured into the area enclosed by the concrete contact surface 15 of the panels 1, and the formwork and scaffolding are fixed to the outside of the overall fixing surface 24 of the fixing plate 2.

[0044] Correspondingly, in order to cooperate with the fixing of panel 1, the fixing plate 2 as a whole can also be at a certain angle, arc, etc.

[0045] Secondly, panel 1 and fixing plate 2 can be made of one or more of the following materials: polyvinyl chloride, polypropylene, polycarbonate, and high-density polyethylene.

[0046] Compared to wooden formwork, these plastic materials do not absorb moisture from the poured concrete and do not affect the concrete formula. Compared to aluminum alloy formwork, plastic materials have a lower thermal conductivity, reducing the temperature difference between the surface and the interior of the poured concrete and lowering the probability of cracks. On the other hand, these materials are thermoplastic and can be recycled after the formwork is damaged, avoiding environmental pollution.

[0047] Working principle: Place panel 1 in the required position, with the concrete contact surface 15 of panel 1 facing the position of the concrete component to be poured. Fine-tune the position of panel 1 so that the sealing rubber strips 13 on the contact sides of the two spliced ​​panels 1 are flat and in contact, fully filling the splicing gap. Then install the corresponding fixing plate 2, so that the corresponding fixing protrusions 21 are divided into two or more groups with the connecting side of the adjacent panels 1 as the boundary. Each group of fixing protrusions 21 is fixedly installed in the installation grid 14. According to the architectural design requirements, repeatedly connect and fix the panels 1 and fix the fixing plate 2 until the requirements of the architectural construction drawings are met. When dismantling, remove the fixing plate 2 and then separate the corresponding panels 1.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
