Description

Technical Field

[0001] The utility model relates to the field of building formwork, in particular to a building formwork with self-sealing splicing. Background Technique

[0002] The wooden formwork used in building construction is a temporary support structure, which is made according to the design requirements, so that the concrete structure and components are formed in accordance with the specified positions and geometric dimensions, maintain their correct positions, and bear the self-weight of the building formwork and the external loads acting on it. The purpose of carrying out the formwork project is to ensure the quality of the concrete project and construction safety, speed up the construction progress and reduce the project cost.

[0003] At present, such wooden formwork is a building formwork in which multiple layers of thin wooden formwork are bonded together by industrial glue (phenolic glue, melamine glue or white glue). After multiple formwork are spliced and combined with each other, they jointly form a shaping structure. When the formwork are spliced, the splicing seams need to be kept closed and tight to prevent leakage after the subsequent pouring of concrete.

[0004] However, most of the wooden formwork on the market at present are regular rectangular plate structures, and their outer side wall structures are relatively simple. During the construction splicing process, it is often necessary to use external small plates to supplement the connection at the splicing seams and then fix them with nails. In actual operation, this method requires full-time support and control of the later-spliced formwork, does not have the ability of pre-fixation, and a single person cannot operate. Moreover, during the splicing process, the accidental swing of the support and control end will affect the splicing tightness and the construction quality. Content of the Utility Model

[0005] The utility model provides a building formwork with self-sealing splicing, which is beneficial to solve the problems that the outer side structure of the existing building formwork is relatively simple, the splicing operation is difficult and the controllability of the splicing gap is poor.

[0006] The utility model is realized as follows:

[0007] A building formwork with self-sealing splicing includes a plate body, the plate body is of a rectangular structure, and two opposite side edges of the plate body are respectively provided with a first convex rib and a second convex rib, the first convex rib and the second convex rib are longitudinally offset, and two adjacent plate bodies can form a pre-fixed structure connected end to end by longitudinally abutting against each other with the first convex rib and the second convex rib; a notch is provided on the first convex rib, and a convex block adapted to the notch is provided on the second convex rib. When pre-fixed, the convex block can be inserted into the notch to form a limiting structure; sealing members are provided on the other two side edges of the plate body except for the first convex rib and the second convex rib, the sealing members are wedge-shaped strips with a narrow lower part and a wide upper part made of elastic material. After two adjacent plate bodies are spliced with each other, the sealing members will be extruded and deformed to form a self-sealing structure in the splicing seam.

[0008] On the basis of the above technical solution, a plurality of notches distributed at intervals are provided on the first convex ridge, and a plurality of protrusions corresponding to the notches are provided on the second convex ridge.

[0009] On the basis of the above technical solution, a plastic part with a "U"-shaped structure is fixed in the notch, and the plastic part is made of rigid material.

[0010] On the basis of the above technical solution, elastic gaskets are provided on the left and right inner walls of the shaping member.

[0011] Based on the above technical solution, an anti-skid sheet is provided on the inner side wall of the elastic gasket, and evenly distributed wrinkles are provided on the inner side wall of the anti-skid sheet, and the wrinkles form a rough surface structure on the inner end surface of the anti-skid sheet.

[0012] On the basis of the above technical solution, a distance is left between the top of the sealing member and the top surface of the plate body, and the distance can form a deformation gap after adjacent plates are spliced.

[0013] On the basis of the above technical solution, the board body is formed by stacking a number of wooden boards.

[0014] On the basis of the above technical solution, the outer end surface of the shaping member is arranged to fit the inner wall of the notch.

[0015] Based on the above technical solution, the anti-slip sheet is located at the longitudinal center of the elastic gasket.

[0016] Compared with the prior art, the utility model has at least the following advantages:

[0017] The utility model sets longitudinally displaced first and second ridges on a set of corresponding side edges of the plate body. The first and second ridges can quickly form a head-to-tail joint when two adjacent plates are spliced. With the help of notches and convex blocks, a pre-fixed structure can be formed to help the template quickly and conveniently complete pre-fixation during the construction process. This head-to-tail joint method can also make its joint seam present a displaced broken line path, which has a better sealing effect. The other two sides of the plate body are provided with seals with a narrow lower and wide upper wedge-shaped strip structure. After two adjacent plates are spliced ​​together, the seals will be squeezed and deformed to form a self-sealing structure in the splicing seam. Therefore, this structure is conducive to solving the problem that the outer side structure of the existing building template is relatively simple, the splicing operation is difficult, and the splicing gap controllability is poor.

[0029] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Embodiment 1: In combination with Figures 1 to 5 , this embodiment discloses a spliced self-sealing building formwork, including a plate body 1. The plate body 1 is a rectangular structure throughout. The plate body 1 is composed of a plurality of wooden boards stacked and compounded. The plate body 1, as the main structure of the formwork, can play a role in shaping and supporting components in building construction.

[0031] On two opposite sides of the plate body 1 (defined as the front and rear sides in this embodiment), a first convex rib 11 and a second convex rib 12 are respectively provided. The first convex rib 11 and the second convex rib 12 are longitudinally offset. The first convex rib 11 is located at a relatively lower position, and the second convex rib 12 is located at a relatively higher position. During use, two adjacent plate bodies 1 can form a pre-fixed structure connected end to end by longitudinally abutting against each other with the first convex rib 11 and the second convex rib 12. After the first convex rib 11 and the second convex rib 12 are joined, their joint seam presents a longitudinally offset zigzag path, and this structure has a better sealing effect.

[0032] Furthermore, a notch 2 is provided at the top of the central position of the first convex rib 11. The notch 2 is a sunken groove structure relative to the first convex rib 11, and its front side and top are open structures; in combination with Figure 2 as shown, a convex block 3 adapted to the notch 2 is provided at the bottom of the central position of the second convex rib 12. The convex block 3 is a downward flange structure relative to the second convex rib 12. The outer contour of the convex block 3 fits and abuts against the inner contour of the notch 2. When two adjacent formworks are pre-fixed, the convex block 3 can be inserted into the notch 2 to form a limiting structure, making the joint between the first convex rib 11 and the second convex rib 12 more stable and reliable.

[0033] Further, a shaping member 4 with a "U" - shaped structure is fixedly arranged in the notch 2. The shaping member 4 is made of a rigid material (aluminum alloy). The outer end face of the shaping member 4 is attached to the inner wall of the notch 2 and is bonded by composite glue. The function of the shaping member 4 is to stabilize the contour shape of the notch 2, prevent it from being damaged after frequent use and unable to function properly. That is to say, the shaping member 4 can enhance the structural durability of the notch 2 and extend its service life.

[0034] In order to make the engagement during pre - fixation more reliable and prevent them from separating from each other, elastic gaskets 5 are arranged on the left and right inner walls of the shaping member 4. The elastic gaskets 5 can provide a certain degree of lateral elastic support, which makes the convex block 3 more firmly embedded in the notch 2, and the clamping gap can be kept in stable contact under the influence of the elastic gaskets 5.

[0035] Further, combining Figure 3 and Figure 4 , anti - slip sheets 6 are arranged on the inner walls of the elastic gaskets 5. Uniformly distributed corrugated portions 61 are arranged on the inner walls of the anti - slip sheets 6. The corrugated portions 61 make the inner end face of the anti - slip sheet 6 form a rough surface structure. The anti - slip sheet 6 is located at the longitudinal center position of the elastic gasket 5. The anti - slip sheet 6 can provide a certain degree of anti - slip effect due to the corrugated portions 61, so that the clamping block will not easily fall off from the notch 2.

[0036] Combining Figure 1 , sealing members 7 are arranged on the other two sides (the left and right sides in this embodiment) of the plate body 1 except for the first convex rib 11 and the second convex rib 12. The sealing member 7 is a wedge - shaped strip structure with a narrow bottom and a wide top made of an elastic material (rubber). Combining Figure 5 as shown, after two adjacent plate bodies 1 are spliced, the sealing member 7 will be squeezed and deformed. This deformation can automatically fill the joint gap on the left and right sides of the two templates, forming a self - sealing structure in the splicing seam.

[0037] Embodiment 2: On the basis of Embodiment 1, combining Figure 6 as shown, there is a spacing between the top of the sealing member 7 and the top surface of the plate body 1. This spacing can form a deformation gap 8 after adjacent plate bodies 1 are spliced. This structure optimizes the assembly position of the sealing member 7, avoids the situation that adjacent templates cannot be fully closed due to the excessive occupation of the sealing member 7 when joining at the left and right side end faces. And the deformation gap 8 provides a certain degree of accommodation space for the squeezed sealing member 7 to expand and deform outward. On the basis of taking into account the joint tightness of the main structure, filling the deformation gap 8 can improve the sealing effect.

[0038] In other embodiments, in order to further improve the stability of pre - fixation, a plurality of notches 2 are arranged at intervals on the first convex rib 11, and a plurality of convex blocks 3 corresponding to the notches 2 one by one are arranged on the second convex rib 12.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
