A type of splicing casting formwork

Abstract

This invention discloses a modular casting template, comprising connecting pipes and tubular modules with connecting holes. The connecting pipes pass through the connecting holes of several tubular modules to connect them into a casting side mold. The tubular modules located at both ends of the casting side mold serve as end connectors. At least two casting side molds are connected by the end connectors to form the mold cavity of the cast part. The end connectors are detachably connected. Because the connecting pipes pass through the connecting holes of several tubular modules to connect them into a casting side mold, the size of the casting side mold can be changed by adding or removing tubular modules or selecting tubular modules of different lengths. It has strong versatility, which can significantly reduce the waste caused by the one-time scrapping of traditional steel molds, and also save the time consumed when manufacturing traditional molds of the corresponding specifications each time.

Description

Technical Field

[0001] This invention relates to a splicing casting template. Background Technology

[0002] As an important component of prefabricated assembled buildings, concrete slabs require the assembly of formwork before concrete is poured into them. Currently, most concrete slab formwork is made of four welded steel plates.

[0003] Currently, once the cast-in-place slab formwork is welded, it can only be used to produce concrete slabs of the same size and specification for a single project. Due to its poor versatility, the formwork is discarded after pouring concrete slabs of the same size and specification, and cannot be reused, resulting in a significant waste of steel formwork. When producing cast-in-place slabs of various specifications, the manufacturing of corresponding molds also consumes considerable time, potentially causing delays in tight schedules. Therefore, it is necessary to propose a modular cast-in-place formwork to achieve high versatility, convenient assembly, and cost savings. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide a splicing casting template to achieve strong versatility and cost savings.

[0005] To achieve the above objectives, the technical solution of the present invention is to provide a splicing casting template, including a connecting pipe and a tubular module with connecting holes. The connecting pipe passes through the connecting holes of several tubular modules and connects them to form a casting side mold. The tubular modules located at both ends of the casting side mold serve as end connectors. At least two casting side molds are connected by end connectors to form the mold cavity of the casting component. The end connectors are detachably connected.

[0006] Since the connecting pipe passes through the connecting holes of several tubular modules to connect them to form the casting side mold, the size of the casting side mold can be changed by adding or removing tubular modules or selecting tubular modules of different lengths. It is highly versatile and can greatly reduce the waste caused by the one-time scrapping of traditional steel molds. It can also save the time consumed when traditional molds of the corresponding specifications need to be manufactured each time.

[0007] Preferably, the tubular module includes an upper plate, a lower plate, an inner plate, and an outer plate forming a connecting hole, wherein the inner plate is a plate surface disposed on one side of the casting component.

[0008] As a preferred structure of the end connector, the end connector includes a first connector and a tail connector located at both ends of the casting side mold. The four casting side molds are connected end to end in sequence through the first connector and the tail connector to form the mold cavity of the casting part.

[0009] As a preferred structure for the first connector and the tail connector, the first connector includes a first connecting plate disposed on the upper plate. The upper plate of the first connector is connected to one end of the first connecting plate. The other end of the first connecting plate extends to one side of the adjacent tail connector and is provided with a first connecting hole on one side of the extended end. The tail connector is provided with a second connecting plate on its outer side. The second connecting plate is provided with a second connecting hole corresponding to the position of the first connecting hole. The first connecting hole and the second connecting hole are connected by bolts or pins.

[0010] Preferably, in order to limit the position of the connecting pipe, as a preferred structure of the first connecting member, the first connecting member is provided with a connecting pipe fixing hole that penetrates its inner plate and outer plate, the connecting pipe is provided with a through hole corresponding to the connecting pipe fixing hole, and the connecting pipe fixing hole and the through hole are connected by bolts or pins.

[0011] To secure the assembled casting template, preferably, the bottom of the tubular module has a fixed bottom edge extending to one side of the outer plate.

[0012] As another preferred structure for the first and tail connectors, the first connector has a third connecting plate on its outer side, and a third connecting hole on the third connecting plate. The tail connector has a fourth connecting hole that penetrates its inner and outer plates. The fourth connecting hole corresponds to the third connecting hole and is connected by bolts or pins.

[0013] Preferably, to facilitate the arrangement of reinforcing bars and the fixing of connecting pipes, the tubular module is provided with fixing pin holes and / or reinforcing bar holes penetrating its inner and outer plates. The fixing pin holes are provided with matching fixing pins. The fixing pin holes include square holes, one side of which corresponds to the bottom of the connecting pipe. One side of the fixing pin is wedge-shaped and has a limiting hole. The other side of the fixing pin adjacent to the wedge is provided with a limiting step. The limiting step and the limiting hole on the fixing pin are located on the outer sides of the inner and outer plates of the tubular module, respectively. The reinforcing bar holes are inverted U-shaped holes.

[0014] To facilitate demolding of the cast slab, preferably, the inner plate of the tubular module is provided with a guide hole, and a guide screw is provided in the guide hole for sliding engagement. The threaded end of one end of the guide screw is connected to a push block located on the outer side of the inner plate by a thread. A compression spring is provided between the head of the other end of the guide screw and the inner wall of the tubular module and is sleeved on the guide screw. The tubular module is provided with a push screw hole that penetrates its inner plate and outer plate. A push bolt adapted to it is provided in the push screw hole, and the head of the push bolt is located on the outer side of the outer plate.

[0015] To support the connecting pipe, another preferred solution is that a partition is provided between the upper and lower plates of the tubular module, and the shape of the hole formed between the upper surface of the partition and the tubular module is adapted to the cross-sectional shape of the connecting pipe.

[0016] The beneficial effects of this invention are as follows:

[0017] Firstly, since the connecting pipe passes through the connecting holes of several tubular modules to connect them to form the casting side mold, the size of the casting side mold can be changed by adding or removing tubular modules or selecting tubular modules of different lengths. It has strong versatility, which can greatly reduce the waste caused by the one-time scrapping of traditional steel molds, and can also save the time consumed when it is necessary to manufacture traditional molds of the corresponding specifications each time.

[0018] Second: The fixing pin plate can effectively support and fix the connecting pipe.

[0019] Third: The setting of the rebar holes facilitates the pre-embedding of rebars in the cast slab.

[0020] Fourth: The push block and push bolt facilitate the demolding of the cast slab. Attached Figure Description
