Description

Structure for connecting and jointing square still supporting beam in temporary soil sheathing and reinforcing members for the same}

The present invention in the construction structure of rectangular steel pipe using a joint reinforcing member for connecting the reinforcement of the square steel pipe to each other and the joint reinforcing member for the connection between the support and the belt or jack support in the temporary earthquake construction method applied to the urban excavation construction In more detail, the connecting reinforcing member in the form of fastening facing up and down in more detail, it is possible to facilitate the connection between the square steel pipe brace at the installation position of the square steel pipe brace, the joint reinforcing member is connected to the square steel pipe brace and the belt or belt By making stable and easy joining with the combined jack support, the construction time for the square steel pipe brace in the temporary construction of the construction and the connection and joint strength is improved.

In the general construction site, temporary earthquake works are carried out in the usual way to prevent soil collapse and suppress displacement of the back of the excavation during ground excavation for structural construction (civil engineering / construction site), and to support the earth pressure acting on the back of the excavation. The support method for this is applied, and generally the support method or anchor method is applied.

At this time, the reinforcement method is to install the bands fixed in the transverse direction with respect to the earth wall, and install a plurality of reinforcement beams crossing the bands facing each other to support the earth pressure acting on the earth wall. The application method is applied. Such a bracing method would have to extend the length of the bracing beam according to the spacing of the facing bands.

However, the H-Pile brace method, which is used most frequently in the construction of temporary fences, does not have a problem about the connection between the braces. The weak axis is present, and because the buckling occurs in the weak axis direction, displacement of the H-Pile occurs, so that the earth pressure on the rear surface of the excavation cannot be effectively supported. Accordingly, in order to prevent the buckling, a reinforcement work for installing horizontal and vertical reinforcement materials in the weak axis direction is required. Therefore, an increase in the amount of steel used and reinforcement installation work are additionally required.

Unlike the H-Pile, the reinforcement method using the circular steel pipe has the advantage that the weak axis and buckling does not exist, so there is no need for reinforcement of the weak axis because there is no buckling problem for the weak axis, but the worker steps on the reinforcement like the H-Pile method. It can't serve as a path to move around.

In addition, since the work for connecting the braces cannot be performed in the air where the braces are directly installed, the braces are assembled in a separate workshop, and then the entire entire brace system is mounted at the installation position by lifting equipment such as a large crane. The same process must be carried out in reverse order, so the work process is very complicated and there is always an accident risk.

In addition, unlike the H-Pile brace method, since the brace method using the circular steel pipe does not secure a space for rotating the bolt or nut in the fastening of the bolt, an additional bracket device or an extension joint is additionally configured. They require a lot of additional preliminary and preliminary work because they need to be connected to each other, and this preliminary and preliminary work adds to the cost of construction due to the delay of air as well as the occurrence of additional labor costs and the use of a large amount of steel. It is pointed out as the cause.

The present invention has been made to solve the problems described above, and provided with a joint reinforcing member having a coupling structure of the upper and lower facing structure and the joint reinforcement member and the coupling of the band length, and through the connection reinforcing member Is to make the connection between each other in a state to sit the brace to be connected at the installation position, and through the joint reinforcing member made of easy and stable fastening of the square steel pipe brace and the band or square steel pipe brace and jack support The present invention provides a connection reinforcement member and a connection reinforcing member and a connection reinforcing member for the construction structure of the rectangular steel pipe reinforcement for a temporary earthquake method, which rationally overcomes the problems of the conventional general reinforcement method. There is a purpose.

When the first connecting reinforcing member and the second connecting reinforcing member face each other up and down, the first and second square reinforcing pipes are fastened by fastening and fixing the first connecting reinforcing member and the second connecting reinforcing member. To make the connection to the brace

In order to join the end of the rectangular steel tube brace with a strip or jack support, the joint reinforcing member having an insertion portion for accommodating the end of the rectangular steel tube brace is made to be fastened to the insertion portion and the square steel tube brace, The other side is to be formed to be joined to each other through the joint reinforcement member and the rectangular steel pipe brace and the strip and jack support by forming a joint with the belt or jack support.

In the present invention, in connecting the braces installed between the bands facing each other, one end of the braces to be connected can be seated on the connecting reinforcing member so that the connection and dismantling at the installation position for the braces is possible, It is to make stable and efficient joining even when joining fastened jack support and square steel pipe.

It is to play a role that greatly improves the structural rigidity and connection performance of the square steel tube brace (10, 10 ').

In addition, the connecting reinforcing members 20 and 20 'having the same shape and coupled up and down in opposite directions at opposite ends of the first square steel tube brace 10 and the second square steel tube brace 10'. The coupling flanges 22 and 22 'formed on the upper and lower connection reinforcing members 20 and 20' in a state in which the rectangular steel pipe braces 10 and 10 'are disposed in a straight line are spaced apart from each other by a predetermined distance. When the upper and lower connecting reinforcing members 20, 20 'is fastened by using bolts and nuts, the entire connecting reinforcing members 20, 20' are square steel tube supports 10 and 10 '. Pressing the outer surface of the) acts to tighten, so that the bonding force between them is greatly increased.

In addition, a plurality of reinforcing pieces (26) and (26), which are connected and fixed between the coupling flanges (22) and (22 ') and the vertical portions (23) and (23') of the connecting reinforcing members (20, 20 '). ') Also increases the structural and physical rigidity of the connecting reinforcing members (20, 20'), resulting in buckling or deformation from the high compressive stress acting on the connecting reinforcing members (20, 20 '). Of course, the rigidity of the coupling flanges 22 and 22 'is greatly increased, and thus the square steel tube braces 10 and 10' can be more firmly connected and fixed.

The connection reinforcing member 20, 20 'of the present invention as described above will be able to be bent or formed into a cast steel sheet having a predetermined thickness, after cutting the square steel pipe of the appropriate thickness coupling flange 22 The 22 'may be manufactured by welding or the like, and the reinforcing plate 21 and 21' may be welded and fixed in a state where a fat groove is formed in the center for weight reduction. .

5 to 7 illustrate a joint reinforcing member 30 for directly joining the already installed strip 40 and the square steel tube braces 10 and 10 'to each other or to a jack support 50 used in the related art. It is.

The joint reinforcing member 30 has a rectangular insertion portion 31 having an inner width for inserting the end portions of the square steel tube braces 10 and 10 ', and on one side of the insertion portion 31, a reinforcing material 32 ) Is formed, and the fastening plate 33 is formed at the end of the reinforcing material (32).

In addition, the insertion portion 31 and the fastening plate 33, respectively, fastening holes 34 and 34 for coupling with the square steel tube braces 10, 10 'and the strip 40 or the jack support 50, respectively. ') Is formed through, and between the insertion portion 31 and the fastening plate 33, support pieces 35 and 35' at positions corresponding to the outer surface of the reinforcing material 32 are connected in all directions. It is.

In particular, the reinforcing member 32 is composed of a polyhedron formed by bending a metal plate, the polyhedron reinforcing member 32 provides an effective support force from the high compressive stress acting in the axial direction so that the joint reinforcing member ( 30) greatly increases the physical stiffness and thus is safe from buckling or deformation, and the support pieces 35 and 35 'also serve to prevent buckling or deformation of the joint reinforcing member 30 from compressive stress in the axial direction. As a result, the rigidity of the square steel pipe braces (10) (10 ') and the band 40 or the square steel pipe braces (10) (10') and the jack support (50) through the joint reinforcing member 30 having a high physical rigidity. Bonding can be made.

At this time, the insertion part 31 is formed by bending the metal plate or cutting the rectangular steel pipe, so that both sides will be open, so that the finishing work for one side will be performed. In this case, the insertion part 31 and Separate support plates 36 having the same width and width are used. Accordingly, the reinforcing material 32 and the support piece 35, 35 ′ will be fixed on the supporting plate 36 by welding or the like, and the fastening plate 33 may be fixed with such a reinforcing material 32. Since the end portions of the support pieces 35 and 35 'will be welded, these inserts 31 and the reinforcement 32 and the fastening plate 33 and the support pieces 35 and 35' and the support plate 36 will eventually be formed. ) Has an integrated connection structure, which greatly increases the structural rigidity.

In addition, the reinforcing material 32 is made of a polyhedron, preferably in the form of an octagonal column having a trapezoidal cross section between the fastening plate 33 and the support plate 36 to form a fixed action to act in the axial direction It is ideal to design the structure to be able to resist the compressive force, and the joint reinforcing member is formed by reinforcing and forming the support pieces 35 and 35 'which are described in the flat side portions of the octagonal trapezoidal columns as described above. 30 is effective bearing force from the high compressive stress acting in the axial direction.

Connection and joint construction for the square steel pipe braces (10, 10 ') through the connection reinforcing member 20, 20' and the joint reinforcing member 30 as described above can be made reasonably and effectively, the above connection The reinforcing pieces 26, 26 'and the support pieces 35, 35' applied for the purpose of increasing the structural rigidity with respect to the reinforcing members 20, 20 'and the joint reinforcing member 30 are formed between the braces. It may interfere with each other's fastening by rotating bolts and nuts in the process of connection or jointing between the brace and the belt or the brace and the jack support.

That is, in fastening the rectangular steel pipe braces 10, 10 'and the connecting reinforcing members 20, 20' to each other, the fastening holes 25, 25 'from the outside of the connecting reinforcing members 20, 20'. Bolts that are fitted with) will not interfere with the rotational tightening of the tool, but in the case of nuts that will be placed inside the square steel braces (10) (10 '), they cannot be reached or faced with situations where the tool cannot be inserted. In the case where the joint reinforcing member 30 and the strip 40 or the jack support 50 are to be joined, one of the bolts or nuts may be the reinforcing piece 26 or 26 'or the supporting piece. Interference from (35) (35 ') will lead to a state in which it cannot provide a firm clamping force. This is the main reason why the conventional joining device was not able to add a separate reinforcing piece, etc. despite the problem of surface buckling.

Accordingly, in the present invention, the use of a separate fixing nut 60 as shown in Figure 8 in the difficult to enter or access the operator's hand or tool, as described above, even with the rotation of the bolt 70 is firmly mutually The fastening is to be made.

That is, the fixing nut (60) is a state in which the fitting portion 61 protrudes to one side, and the interference protrusion 62 is formed on the outer surface of the fitting portion 61.

Accordingly, in the narrow fastening portion where the operator's hand or tool is not allowed to enter or approach or have a radius of rotation, the fastening holes 11, 11 ′ or connecting reinforcing members 20 formed in the square steel braces 10, 10 ′. ) 20 'to the fastening holes 25 and 25' or the fastening holes 34 and 34 'formed in the joint reinforcing member 30 to force the fitting portion 61 of the fixing nut 60. When the pressure coupling is applied, the fixing nut 60 is the interference protrusion 62 of the fitting portion 61 is fastening holes 11, 11 'or connection reinforcing member 20 of the square steel tube braces 10, 10'. (20 ') of the fastening holes 25, 25' or bonding reinforcing members 30, 30 'of the fastening holes (34, 34') of the inner surface is forcibly coupled to the fixed state can be fixed It will be so that only the separate bolt 50 is rotated to be screwed together.

Looking at this in detail, to insert into the bolt hole using a conventional bolt used in the conventional fastening method H-Pile or round steel pipe, there is a problem of securing a space for the bolt or nut rotation, alternatively round steel pipe Et al. Generally employ two alternatives:

The first alternative is to use the bolt hole as a substitute for the nut. In order to apply the method, the thickness of the member on which the bolt hole is formed must increase by 20 mm or more. Another method applied to the other alternative is to join the nut to the steel pipe by welding or the like. This method also removes the bolt head only when the bolt deformation occurs. This makes it difficult to reuse the connecting reinforcement member.

Accordingly, the present invention is to join the square steel pipe braces 10, 10 'and connecting reinforcing members 20, 20' or square steel pipe braces 10, 10 'as shown in FIG. When bonding the reinforcing member 30 to each other or to join the bonding reinforcing member 30 and the strip 40 as shown in Figure 10 or to join the bonding reinforcing member 30 and the jack support 50 In this case, the additional bolt 70 in the state in which the fixing nut 60 is pressed and fixed to any one of the fastener yoke (which is difficult to access or rotate the operator's hand or tool) among the matching holes. ) Can be screwed together to obtain a solid binding force without difficulty.

In addition, since the fixing nut 60 is temporarily fixed by a type force such as a hammer, the fixing nut 60 may be easily removed and removed by a blow when the fixing nut 60 is unnecessary. ') Or connecting reinforcing member 20, 20' or bonded reinforcing member 30 can be repeatedly reused as it is in its original form, and the fixed nut 60 is also retaining its appearance since the fixing nut 60 remains fixed as it is. It is very economical and reasonable because it can be reused where it is needed.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the present invention as defined by the appended claims.
