Description

Technical Field

[0001] This utility model belongs to the field of building formwork technology, specifically spliced ​​building formwork and its locking and disassembly structure. Background Technology

[0002] Interlocking formwork is a formwork system assembled using standard-sized panels and connectors, widely used in concrete pouring processes during building construction. In related technologies, interlocking formwork typically involves creating mounting holes on the sides of the panels and connecting adjacent panels using connectors. However, the multiple connectors used to connect the formwork are usually independent of each other, requiring the sequential installation and removal of connectors during assembly and disassembly. This reduces the efficiency of interlocking formwork assembly and disassembly, and stress at the formwork joints is often concentrated on the connectors, reducing the strength of the joints.

[0003] Especially during the continuous construction of long strip foundations, traditional formwork is inefficient and complex, requiring multiple people to work together. Disassembled formwork cannot be quickly reused for the next section of construction, and re-formwork increases construction costs. Furthermore, due to the large size of some building foundations and the large amount of concrete used in their strip foundations, insufficient clamping force at the formwork joints can easily lead to problems such as formwork overturning at the joints, causing concrete leakage and formwork bursting.

This kind of template is suitable for pouring long strip bases and the like, can realize rapid and continuous splicing, can realize rapid and convenient dismounting, and is also convenient for repeated use.

[0031] The locking and dismounting structure provided by the present disclosure comprises a fixing part and a connecting part, the fixing part comprises two fixing plates 1 and a first limiting rod 6, both ends of one side of the template body 12 are fixedly connected with the fixing plates 1, the fixing plates 1 are uniformly provided with through holes 2, the end part of the first limiting rod 6 is movably connected with the inner cavity of the through hole 2, the inner side of the through hole 2 is fixedly connected with a guide pipe 3, the end part of the first limiting rod 6 is movably connected with the inner cavity of the guide pipe 3, as Figures 2 to 6 The two fixing plates 1 are connected through the first limiting rod 6. The middle part of the first limiting rod 6 is fixedly connected with a push rod 5, the push rod 5 is connected with one fixing plate 1 through a first spring 4, under the action of external force, the first limiting rod 6 can move in the direction where the guide pipe 3 is located, when the restriction on the first limiting rod 6 is removed, under the action of the elastic force of the first spring 4, the first limiting rod 6 can be reset, and when the first limiting rod 6 is reset, the end of the first limiting rod 6 away from the push rod 5 is in the same plane with the end of the fixing plate 1 away from the push rod 5, the distance value between the ends of the two fixing plates 1 away from the guide pipe 3 is the same as the length value of the first limiting rod 6. And the fixing plate 1 can also support and reinforce the template body 12, thereby increasing the strength of the template body 12.

[0032] Two adjacent first limiting rods 6 are connected by the push rod 5, and the user can drive multiple first limiting rods 6 to move simultaneously by the push rod 5, thereby improving the convenience of use. The middle part of the push rod 5 is provided with a first positioning hole 16. The first positioning hole 16 and the second positioning hole 14 are matched with the positioning piece 15. When the first positioning hole 16 is aligned with the second positioning hole 14, the push rod 5 can be fixed together with the template body 12 by using the positioning piece 15, thereby realizing the fixation of the position of the first limiting rod 6. The positioning piece 15 can adopt the form of a latch to simultaneously pass through the first positioning hole 16 and the second positioning hole 14 to limit the movement of the first limiting rod 6. Of course, the positioning piece 15 can also adopt a bolt. At this time, at least one of the first positioning hole 16 and the second positioning hole 14 adopts a threaded hole.

[0033] The connecting part includes a sealing strip 7 and a connecting assembly 8 connected with the sealing strip 7. The transverse part of the sealing strip 7 is matched with the clamping groove 13. The sealing strip 7 can realize the clamping between two adjacent template bodies 12, as shown in Figure 6 The two template bodies 12 are in a multiple sealing state. The contact area between the locking and dismounting structure and the template body 12 is increased, the stress concentration is reduced, the strength of the template splicing part is improved, the probability of liquid leakage of the splicing type template is reduced, and the use of the splicing type template is facilitated.

[0034] The length value of the short side of the longitudinal part of the sealing strip 7 is less than the length value of the long side of the transverse part of the connecting assembly 8. The length value of the long side of the longitudinal part of the sealing strip 7 is the same as the thickness value of the template body 12. When the sealing strip 7 is clamped with the template body 12, the connecting assembly 8 is in close contact with one side of the template body 12, thereby further improving the sealing performance of the template body 12 splicing. The distance value between the end part of the template body 12 and the adjacent fixed plate 1 is half of the long side of the transverse part of the connecting assembly 8.

The problem of mold explosion is less likely to occur at the part where the sealing strip 7 is located, and the concrete is less likely to break the joint in the direction perpendicular to the template at the connecting part.

[0036] In other examples, the outer diameter of the second limiting rod 9 and the first limiting rod 6 can also be set to be different, at this time, the outer diameter of one end of the second limiting rod 9 can be increased, and then a groove capable of embedding the end part of the first limiting rod 6 is set at the end part, at this time, when it is as shown in the description, Figure 3 the combined form can be that one end of the first limiting rod 6 is embedded in the groove at the left end of the second limiting rod 9, and the two are nested, which can not only ensure that the first limiting rod 6 can effectively drive the second limiting rod 9, but also ensure that the two are nested to form a whole, increase the rigidity of the connecting part of the two, especially the rigidity perpendicular to the length direction, and increase the supportability to the template; then the other end adopts the second limiting rod 9 with a reduced outer diameter, and a nesting hole is set at the left end of the first limiting rod 6 of the other group of templates, and the specific principle is the same as before, and no more description is made. Of course, this form is an optional item of some examples, and is not a necessary item.

The spring is used to store energy in compression deformation or tensile deformation according to the specific installation position in actual application, the elastic force includes the elastic force after compression and the elastic force after stretching, which is not particularly limited and can realize the corresponding function.

[0038] As described above, the locking and dismounting structure provided by the present disclosure can change the positions of all the first limiting rods 6 and the second limiting rods 9 by moving the push rod 5 at the end, improve the dismounting efficiency of the spliced template, and make the adjacent two locking and dismounting structures be connected into a whole by the first limiting rods 6 and the second limiting rods 9, so as to improve the strength of the spliced template. The second limiting rod 9 and the through hole 2 of the connecting assembly 8 can also be better adapted, so the guidance is not considered here, as long as the second limiting rod 9 can be pushed and moved by the first limiting rod 6, and can be restored to the standby mode under the action of the second spring 11, the remaining optimization mode is not the core of the present disclosure and is not described in detail.

[0039] As described above, the spliced building template is used, the user first splices the adjacent two spliced building templates together by the connecting part to form a split shape as shown in Figure 6 For the convenience of description, the spliced building template is used in Figure 2Further use of the orientation reference, the fixed part of the locking and dismounting structure located on the left side of the connecting part is set as fixed one, the fixed part of the locking and dismounting structure located on the right side of the connecting part is set as fixed two, after the splicing of the formwork is completed, the formwork fixing operation is carried out. Figure 3 When the formwork is fixed, the user pushes the push rod 5 in the fixed one to the right, the push rod 5 moves and drives the first limiting rod 6 connected thereto to move to the right, the first limiting rod 6 pushes the second limiting rod 9 in contact therewith to move to the right (forms the shape as shown in Figure 6 , the first positioning hole 16 and the second positioning hole 14 are in an aligned state, the user connects the push rod 5 in the fixed one and the formwork body 12 by using the positioning piece 15, so that the position of the push rod 5 is fixed, and at this time the position of the second limiting rod 9 is also fixed. At this time, the right end of the first limiting rod 6 is located in the inner cavity of the connecting assembly 8, and the right end of the second limiting rod 9 is inserted into the inner cavity of the left guide pipe 3 in the fixed two, and the adjacent two locking and dismounting structures can be connected into a whole in turn, and finally form the shape as shown in .

[0040] When the formwork needs to be dismounted, the user separates the positioning piece 15 from the formwork body 12, and releases the limitation on the push rod 5, under the action of the elastic force of the first spring 4 and the second spring 11, the first limiting rod 6 and the second limiting rod 9 are reset, as shown in Figure 6 , the connecting part and the fixed part can quickly move to the left to realize quick separation and recover to the standby state, so that the dismounting efficiency of the splicing type building formwork can be improved.
