Description

Improved structure of building formwork

This creation relates to a formwork device for building grouting, especially an improved structure of building formwork.

According to the prior knowledge, the grouting formwork device for building houses is mainly used in the construction of the exterior wall structure of the construction site. As shown in Figure 6, before the traditional grouting operation, the steel frame is erected at the base and the outer side of the two sides of the design wall. The position A and the inner position B are each wooden formwork unit 1 with a predetermined length and width area. Through the nailing work of many formwork workers, a plurality of wooden formwork units 1 are connected in sequence to form a string to form the two sides of the separated steel bars. An outer wall formwork 1A and an inner wall formwork 1B form a grouting space 2 relatively spaced apart from the outer wall formwork 1A and the inner wall formwork 1B, and the grouting space 2 is filled with concrete-filled grout, which is to be filled with concrete The external wall formwork 1A fixed at the outer position A and the inner wall formwork 1B at the inner position B are removed after the cement slurry is dried, so as to obtain the cement wall structure 3 formed and fixed therein.

However, the above-mentioned traditional grouting formwork device always has the following problems and disadvantages in its construction:

1. Because the Construction Law stipulates that the outer wall of the adjacent building must retain an expansion joint distance F of 10~15 cm, but the narrow space of 10~15 cm of the expansion joint distance F is not enough for the outer wall formwork 1A after grouting. The concrete wall structure 3 after grouting is required for demolition work. Although the wooden inner wall formwork 1B can be removed smoothly, the wooden outer wall formwork 1A opposite to the neighboring building cannot be deeply operated due to the narrow construction space. The wooden exterior wall formwork 1A has to be allowed to accumulate in the expansion joint distance F, and the rainwater erodes and rots, which even aggravates the sewage plug drainage difficulty of the outer cement wall structure 3, and even leads to the occurrence of the leaking wall cancer of the cement wall structure 3 .

2. Even if there are no other buildings next to the construction site to be constructed and are not restricted by the expansion joint distance of the building regulations, the construction of traditional wooden formwork requires the use of a scaffold to provide workers with standing for nailing and binding operations; The scaffold for the construction of the wooden exterior wall formwork 1A needs to be erected on the adjacent land, which often involves the disapproval of the land owner, which increases construction difficulties.

3. Furthermore, the traditional construction method of wooden formwork needs to rely on the craftsmanship of formwork workers to gradually nail pieces of wooden formwork units 1 in sequence to form an exterior wall formwork 1A and an interior wall formwork 1B, which not only constructs Or demolition is time-consuming, and the construction quality is not easy to control.

In view of this, the creator of this case, based on years of experience in producing and marketing similar products, continued to research and experiment, and finally a practical creation was produced.

That is, the main purpose of this creation is to provide an improved structure of building formwork, which can greatly improve the operating efficiency of building formwork and the construction quality of building grouting.

The reason is that, based on this creation, an improved structure of building formwork mainly includes: an outer wall formwork and an inner wall formwork erected on both sides of the interval, and co-constructed to form an outer wall formwork and an inner wall formwork on the opposite side The molding space is filled with concrete to form a cement wall structure with a predetermined thickness; wherein the external wall formwork is horizontally connected and combined by a plurality of waterproof rigid board units, and the rigid board units have a plurality of longitudinal intervals. The extended abutting board surface and the plural parallel notches forming the interval between the abutting board surfaces, and the opposite side edges of the parallel notches are respectively angled Two longitudinal frame plates are arranged to extend in the direction, and the ends of the two longitudinal frame plates are respectively locked with a longitudinally extending positioning plate surface and a diversion groove formed by the parallel notch retracting and extending longitudinally, whereby the longitudinally extending positioning plate surface provides a plurality of The horizontal connection of the connecting element is connected and fixed.

In the improved structure of the building formwork, the rigid plate unit is preferably a steel bearing plate resistant to acid and alkali.

In the improved structure of the building board form, the longitudinal frame board and the abutting board surface form an angle of less than ninety degrees and extend in a folded direction.

In the improved structure of the building board mold, the ends of the longitudinal frame boards at the left and right ends of the rigid board unit are respectively folded and extended to form a corresponding overlap portion.

In the improved structure of the building slab mold, the connecting element which is laid and fixed across the positioning board surface is an L-shaped angle steel.

In the improved structure of the building slab mold, a plurality of longitudinally extending occlusal channels can be arranged parallel and recessed at intervals on the abutting board surface.

In the improved structure of the building formwork, the inner wall formwork 1B is combined with a plurality of wooden formwork units in sequence, vertically and horizontally, and connected together.

Through the above description, the characteristics and effects of this creation are briefly described as follows:

1. In this creation, the external wall formwork is composed of a plurality of rigid board units connected horizontally, and after grouting, the plurality of longitudinally extending abutting board surfaces, the angle-folded longitudinally extending longitudinal frame board and the longitudinally extending positioning board surface, etc. are all combined with cement The wall structure is integrated. Therefore, the cement wall structure not only has an extra layer of protection on the outside, but also increases the structural strength of the building.

2. When this creation is applied to the expansion joints between the building blocks, the external wall template does not need to be removed, and it will not cause the cement external wall to cause drainage difficulties, water leakage, or even wall cancer.

3. This creation eliminates the need to nail the template and the use of scaffolds and other equipment during the construction of the original outer wooden formwork, which can reduce the cost. In addition, because of the feature of the creation that the scaffolding is not required to be overlapped, it will not be used when building houses. Spanning the neighbor’s private land, and construction is easy and fast.

4. Using this creation, the plural parallel notches of the rigid plate unit and the two longitudinal frame plates and the positioning plate are locked to form a constricted longitudinally extending diversion groove, which can effectively guide the rainwater down quickly and greatly reduce the water seepage of the external wall. , Water leakage, breeding wall cancer and other malpractice risks.

5. During construction, the formwork workers can first use L-shaped angles to lock and combine the multiple rigid plate units corresponding to the laps at both ends into an external wall formwork, and then combine the external wall formwork on the ground It is erected and tied and fixed. The operation flow is smooth, and the traditional method does not need to be nailed and assembled piece by piece, which is time-consuming and labor-intensive.

6. This creation saves the trouble of building a scaffold for the outer wooden formwork in the original traditional work to allow the formwork workers to climb up the heights in order to nail and assemble the wooden formwork.
