Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of building engineering, in particular to a formwork fixed structure. BACKGROUND

[0002] The formwork is fixed in horizontal and vertical directions. The horizontal fixing is to fix the adjacent formworks together to prevent horizontal displacement. The vertical fixing is to fix the formworks on both sides or the inner and outer formworks together to prevent vertical displacement. The vertical fixing is mostly achieved by means of the tension bolt, which is used to fix the formworks on both sides together to prevent displacement of the formworks in the width direction. There are various horizontal fixing methods, such as the bolt fixing method, the iron wire binding method, the inclined support connecting method, the spot welding connecting method, etc. The adjacent formworks are assembled together to prevent displacement of the formworks in the length direction. Most of the existing horizontal fixing methods are complicated to operate, and it takes time to install and fix them, which reduces the construction efficiency. In addition, it is difficult to remove the formworks, which further reduces the construction efficiency. SUMMARY

[0003] The present application aims to overcome the shortcomings of the prior art and provide a formwork fixed structure.

[0004] The present application is achieved by the following technical solutions:

[0005] A formwork fixed structure comprises tension bolts, which are used to fix and connect the formworks on both sides together. A plurality of lock tongue portions are arranged on one side of the back ledge at both ends of each formwork, and a plurality of socket portions corresponding to the lock tongue portions are arranged on the other side. The socket portion comprises a fixed plate, which is fixed on the back ledge. A connecting plate is welded to the fixed plate perpendicularly to the back ledge, and an insertion slot is arranged on the upper surface of the connecting plate. The lock tongue portion comprises a T-shaped lock block, the shape of the lower end of which is consistent with that of the insertion slot. The T-shaped lock block can be inserted into the insertion slot. A U-shaped plate is symmetrically arranged on both sides of the T-shaped lock block. The two U-shaped plates enclose a receiving cavity, which is used for the T-shaped lock block to slide up and down. The U-shaped plate is integrally connected with a fixed sheet, which is fixed on the back ledge.

[0006] Preferably, the longitudinal section shape of the insertion slot is triangular.

[0007] Preferably, three lock tongue portions and three socket portions are arranged from top to bottom on the upper part, the middle part and the lower part of the back ledge, respectively.

[0008] Preferably, the fixed plate and the fixed sheet are fixed on the back ledge by means of screws.

[0009] The template fixing structure is simple, adjacent template transverse assembling can be realized by only sliding T-shaped lock blocks up and down, displacement of the template in the transverse direction is avoided, displacement of the template on both sides in the longitudinal direction is avoided through the tension bolt, the template fixing process is simple and fast, the template is convenient to disassemble in the later period, fast assembling and disassembling are realized, and the construction efficiency is greatly improved.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments of the present application.

[0020] The template fixing structure of the embodiment comprises a transverse fixing structure and a longitudinal fixing structure. In the embodiment, the longitudinal fixing structure adopts a tension bolt 1, and the two side templates (inner and outer templates) are fixed and connected together by using the tension bolt 1 to prevent the two side templates from moving in the width direction and also prevent the templates from tilting inward or outward. The tension bolt 1 is a commonly used template fixing structure, and thus will not be described in detail herein. The transverse fixing structure of the embodiment adopts a new structure, which comprises a lock tongue part 3 and a socket part 4. The lock tongue part 3 and the socket part 4 are used to connect adjacent templates together so that the templates cannot move horizontally. The transverse fixing structure will be described in detail below.

[0021] The template transverse fixing structure of the embodiment comprises the lock tongue part 3 and the socket part 4. The lock tongue part 3 is arranged on one end of the back ledge 2 of each template, and the socket part 4 is arranged on the other end of the back ledge 2. The lock tongue part 3 and the socket part 4 correspond to each other. In the embodiment, the lock tongue part 3 or the socket part 4 is arranged on the upper part, the middle part and the lower part of the back ledge 2 of each template. The socket part 4 comprises a fixed plate 41, which is fixed on the back ledge 2 of the side end of the template by using a screw 5. A connecting plate 42 is welded on the fixed plate 41 perpendicularly to the back ledge 2. The connecting plate 42 is perpendicular to the back ledge 2. An insertion slot 43 is arranged on the upper surface of the connecting plate 42. The insertion slot 43 can have various shapes. In the embodiment, the longitudinal section shape of the insertion slot 43 is triangular. The lock tongue part 3 corresponding to the socket part 4 comprises a T-shaped lock block 31. The lower end of the T-shaped lock block 31 has a shape corresponding to that of the insertion slot 43. The T-shaped lock block 31 can slide downward into the insertion slot 43. Two U-shaped plates 32 are symmetrically arranged on the two sides of the T-shaped lock block 31. The two U-shaped plates 32 enclose a receiving cavity 33 for the T-shaped lock block 31 to slide up and down. The U-shaped plates 32 are integrally connected with a fixing piece 34, which is fixed on the back ledge 2 by using the screw 5.

[0022] During construction, the back ledges 2 of adjacent templates are butted together, the socket part 4 and the lock tongue part 3 of the two adjacent templates are corresponded, and then the T-shaped lock block 31 is slid downward into the insertion slot 43 to assemble the adjacent templates together. The opposite templates are connected together by using the tension bolt 1. After being fixed, the concrete can be poured between the two templates.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the same. Those skilled in the art should understand that the technical solutions recorded in the above embodiments can still be modified, or some technical features can be replaced equivalently. The modifications or replacements do not change the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
