Description

Formwork fixing seat and grouting front cavity structure for steel structure

This creation is about a kind of steel structure, especially a template fixing seat and grouting front cavity structure for steel structure.

As we all know, the construction process of general steel structures usually first erect a steel frame, including steel frame columns and steel frame beams, and then use the formwork and steel frame columns and steel frame beams to form a grouting space. In order to strengthen the structure, grouting can be done in advance. A steel mesh body is formed inside the space, so that the grouting space can be used to inject required concrete to form the required wall.

However, the above-mentioned structures used to form the grouting space usually do not adopt modular structure design. Many of them must rely on skilled technicians to assemble and fix them on the spot using nails, strapping and other techniques. For example, common templates are usually wooden The materials usually have to be bound and combined on site, so the assembly operation cannot be completed easily and quickly. When these templates are disassembled, they must sometimes be removed by brute force by special prying work, which makes it difficult to reuse many wooden material templates and the damage rate is extremely high. . At the same time, these wooden templates are usually made up of long strips of wood. In addition, due to their own materials, they cannot form a flat mold surface. Therefore, the wall surface formed by them is quite rough and usually must be flattened and added. Subsequent construction time and cost, so the overall assembly, grouting and disassembly are not easy, the construction period is long, the technical requirements for the construction personnel are high, the template cannot be reused, and the material cost is high. Many shortcomings are necessary to be improved.

This creation provides a template fixing seat for steel structures and a cavity structure before grouting. The template fixing seat includes two template fixing sheets, an inner connecting part connecting the template fixing sheets, and a plurality of forms formed on the template The grouting space between the fixed pieces; this grouting space can be used for the first grouting operation, where the mud can be poured into and cover the inner connecting part of the part, and the covering height of the mud is appropriately lower than the connecting part of the fixed sheet of the template. In order to reserve the connecting part for the space needed for subsequent connecting. Using two of the formwork fixing bases to match at least one steel frame beam, and the formwork assembled between the formwork fixing base and the steel frame beams can form a cavity structure, which can form an external wall or partition wall after grouting body.

The template fixing seat and the cavity structure before grouting provided by this creation are designed in a modular manner. Therefore, they can be easily and quickly assembled to form a cavity structure for grouting, and the required external wall or The partition wall, at the same time, the template can also be easily disassembled and reused. In addition, the template has an integrally formed flat mold surface, so that the formed outer wall or partition wall can have a flat and detailed wall surface. Therefore, there is no need to carry out the leveling project of the wall.

The steel bar 122 can be a commonly used steel bar with an appropriate thickness.

In this embodiment, each of the rectangular frame pieces 121 is connected to a fixing piece 123, and the two sides of the fixing piece 123 are respectively connected to the inner wall surface of the template fixing piece 11. On the one hand, the fixing piece 123 of this embodiment is used to connect and support the template fixing piece 11 to keep the two at a predetermined distance and width, and at the same time, the rectangular frame piece 121 is fixed on it. The template fixing piece 11, the rectangular frame piece 121, and the fixing piece 123 can all be made of metal materials, so that the steel bars 122 can be fixed to each other through welding technology.

As shown in Figures 5-9, this creation further provides a pre-grouting cavity structure for steel structures. The cavity structure 1 can be poured to form an outer wall 2, which includes a steel crossbeam 3 and at least one joint Sheet 20, two template fixing seats 10 as described in claim 1, a plurality of inner templates 30, a plurality of fixing rods 40, and a plurality of outer templates 50; among them:

The connecting piece 20 is connected to the outer side of the steel cross beam 3, and a plurality of connecting parts 21 are formed thereon. It should be particularly noted that the steel cross beam 3 has an inner side 3a and an outer side 3b. The inner side 3a refers to the inner side relative to the steel structure. Similarly, the outer side 3b refers to the outer side relative to the steel structure. And the steel frame beam 3 is a common H-shaped steel frame. It can be clearly seen that a rib 3c is formed between the inner side 3a and the outer side 3b, and the upper and lower ends of the rib 3c are connected to each other with a top The wall 3d and a bottom wall 3e, and an inner top surface 3f is formed on the bottom wall 3e of the outer side 3b.

The connecting piece 20 of this embodiment is L-shaped, and has a transverse part 201 and a longitudinal part 202; the transverse part 201 can be welded and fixed to the inner top surface 3f of the outer side 3b of the steel cross beam 3; the longitudinal part 202 It is used to form the connecting part 21. The connecting part 21 may be presented in the form of perforations.

The inner template 30 is provided with a plurality of first assembling locations 31 on the bottom side and a plurality of second assembling locations 32 on the top side, respectively, so that the inner templates 30 can be laterally connected to each other, by The first assembling parts 31 are respectively detachably assembled and connected to the respective connecting parts 111 of the template fixing sheet 11 inside the template fixing seat 10 that has completed the first grouting operation, and by the second assembling part 32 are respectively detachably assembled and connected to the connecting parts 21 of the connecting piece 20; the connecting piece 20 and the opposite side of the template fixing piece 11 for assembling wall surfaces are aligned with each other in the longitudinal direction.

It can be easily understood that the first assembling part 31 and the second assembling part 32 in this embodiment can also be presented in the form of perforations. Therefore, it can be locked in a common way, for example, through bolts and nuts. , It is easily assembled and locked together with the connecting part 111 of the template fixing sheet 11 and the connecting parts 21 of the connecting sheet 20, so the assembly and disassembly of the inner template 30 are quite simple.

The fixing rods 40 are respectively connected to the bottom end of the template fixing seat 10 and the top wall surface 3g of the steel cross beam 3 that have not yet undergone the first grouting operation, so that the upper template fixing seat 10 is connected to The lower template fixing seat 10 can be vertically aligned up and down. Wherein, the fixing rod 40 can be made of a metal material, so that it can be fixed to the top wall 3g by welding.

The outer template 50 is respectively provided with a plurality of third assembly positions on the bottom side 51, and a plurality of fourth assembling parts 52 are provided on the top side, so that the outer template 50 can be laterally connected to each other, and the third assembling parts 51 are respectively detachably assembled and connected to the lower Each of the connecting parts 111 of the template fixing sheet 11 outside the template fixing seat 10, and the template fixing sheet connected to the upper outside of the template fixing seat 10 are respectively detachably assembled by the fourth assembly part 52 11 Each connection part 111.

It can be easily understood that the third assembling part 51 and the fourth assembling part 52 in this embodiment can also be presented in the form of perforations. Therefore, they can be locked in a common way, such as screwed and locked by bolts and nuts. , The connecting parts 111 opposite to the upper and lower template fixing sheets 11 are easily assembled and locked together, so the assembly and disassembly of the outer template 50 are also quite simple.

Accordingly, a grouting chamber 100 for grouting can be defined between the upper and lower template fixing seats 10, the inner template 30, the outer template 50, and the outer side 3b of the steel-reinforced crossbeam 3, which can be freely located on the upper side. The second grouting operation is carried out at the template fixing seat 10, and the mud a of the second grouting is appropriately lower than the connecting part 111 of the template fixing piece 11 located above. Similarly, it can be reserved The connecting part 111 provides the space required for subsequent connections. For example, when the first grouting is used to form the floor of the first floor, the second grouting is used to form the outer wall 2 between the first floor and the second floor. The floor of the second floor can also be formed at the same time, and so on, before the third grouting, the outer wall 2 and the upper formwork fixing seat 10 can also be assembled on the top to form a cavity Structure 1. After the third grouting and demoulding, the outer wall between the second and third floor 2 and the floor of the third floor are formed. According to this assembly and construction method, a higher level of outer wall and Floor floor.

It should be noted that when the grouting operation is completed, the external wall 2 is formed at the same time Behind the floor, the inner and outer formwork can be easily dismantled, so they can be reused, and the assembly method of modularization and screw locking can be used to easily and quickly complete the assembly and disassembly of the formwork. The general non-traditional senior construction personnel can also be put into the construction of the project through simple training, so it can greatly reduce the labor cost, improve the operation efficiency of the project, and greatly shorten the construction time.

In this embodiment, the cavity structure 1 further includes a steel mesh body 60, which can be contained in the grouting chamber 100 so that it can be covered and covered with the mud during the second grouting. Inside. It is well known that the steel mesh body 60 can be commonly formed by tying a large number of steel bars through the transverse and transverse spacing. After the mud is poured, it can be covered in the mud, so that the structural strength of the formed outer wall 2 can be obtained. Lifting and strengthening are commonly used reinforced concrete structures (Reinforced Concrete Structures, RC for short).

In this embodiment, the cavity structure 1 further includes a plurality of reinforcing components 70, which can be locked to the inner template 30 and the outer template 50 at appropriate places to reinforce and maintain the inner template 30 and the outer template 50 The separation distance.

Furthermore, the reinforcement assembly 70 respectively includes a sleeve 71, a bolt 72 and a nut 73; the sleeve 71 is located between the opposite wall surfaces of the inner mold plate 30 and the outer mold plate 50; the bolt 72 can pass through. The outer template 50, the sleeve 71 and the inner template 30 can be screwed on the nut 73 to keep the two ends of the sleeve 71 against the opposite wall surfaces of the inner template 30 and the outer template 50 respectively. In other words, the design of the reinforcing component 70 can effectively prevent the inner formwork 30 and the outer formwork 50 from being able to maintain a fixed distance under the action of the mud a poured into the grouting chamber 100, without causing problems. The expansion and deformation can also ensure that the formed outer wall body 2 has a uniform thickness. Among them, the design of the sleeve 71 can prevent the bolt 72 from directly contacting the mud a, The bolt 72 can be easily detached from the outer wall 2 after the grouting is completed. As for the sleeve 71, it can be left inside the outer wall 2 or driven out of the outer wall 2 with a specific tool Break away.

In this embodiment, the inner side wall surfaces 33 and 53 of the inner mold plate 30 and the outer mold plate 50 opposite to each other are integrally formed flat mold surfaces. As shown in FIG. 7, the flat mold surface design can ensure the formation of The outer wall body 2 can naturally form a fairly flat and meticulous wall surface after removing the mold, so the subsequent wall leveling project does not need to be carried out, so as to greatly reduce the labor time and cost of the subsequent wall surface construction.

It can be easily understood that the inner template 30 and the outer template 50 can be formed of high-strength metal materials. Compared with the traditional wooden template, the high-strength metal template is not only sturdy and durable, but also easy to cooperate with the general screw lock structure. The simple and fast locking operation facilitates quick assembly and disassembly each time. At the same time, the flat mold surface can be integrally formed to improve the flatness and fineness of the wall surface of the outer wall body 2.

As shown in Figures 10 to 12, this creation further provides another pre-grouting cavity structure for steel structures. The cavity structure 1a is similar to the cavity structure 1 of the above-mentioned embodiment.

Wherein, the first steel-reinforced beam 5 and the second steel-reinforced beam 6 have substantially the same structure as the above-mentioned steel-reinforced beam 3. The only difference is that in this embodiment, two spaced apart steel beams are needed to construct the compartment wall 4, while it is different from the external wall 2 that only requires one steel cross beam.

The third assembling parts 91 are used to detachably assemble and connect to the respective connecting parts 111 of the template fixing sheet 11 on the opposite side of the template fixing seat 10 that has completed the first grouting operation, and by the first grouting operation The four assembling parts 92 are respectively detachably assembled and connected to each of the second connecting parts 23 of the second connecting piece 20b; the wall surfaces of the second connecting piece 20b and the template fixing piece 11 on the opposite side for assembly are aligned with each other in the longitudinal direction .

The fixing rods 40a are respectively connected to the bottom end of the formwork fixing seat 10, which is located above and has not yet undergone the first grouting operation, and the first steel-frame beam 5 and the second steel-frame beam 6 At least any one of the top wall surfaces 5c, 6c allows the upper template fixing seat 10 and the lower template fixing seat 10 to be vertically aligned up and down.

According to this, it is possible to define a joint between the upper and lower formwork fixing seats 10, the first formwork 80, the second formwork 90, the opposite side 5a of the first steel beam 5, and the opposite side 6a of the second steel beam 6 The grouting chamber 101 can be used for grouting, and the second grouting operation can be carried out from the upper template fixing seat 10, and the cover height of the second grouting mud a is appropriately lower than the above template fixing The connecting portion 111 of the sheet 11 is used to reserve space for the connecting portion 111 for subsequent connection.
