Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a narrow groove adjustable steel support device. Background Art

[0002] In the construction or reconstruction of urban roads, it is inevitable to face the construction of rainwater and sewage pipes. The construction of rainwater and sewage pipes requires groove support. Due to the narrow width of the trench excavation, the Larsen steel sheet pile support system is usually adopted. The supports between the existing Larsen steel sheet piles are generally fixed-length steel supports, which are processed into fixed-length support components according to the net distance of the purlin on the support structure. When the trench width changes or the Larsen steel sheet piles deviate vertically after being buried, the steel support can no longer be used and needs to be cut, which is time-consuming, labor-intensive and material-intensive. In addition, the steel support is not pre-loaded with top force and is not tightly combined with the purlin, which reduces the use effect of the steel support and poses certain safety hazards. Therefore, it is urgent to invent an adjustable steel support to solve the above problems. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0015] Figure 1 It is a structural schematic diagram of the utility model of a narrow groove adjustable steel support device. DETAILED DESCRIPTION

[0016] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0017] In the description of the utility model, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0018] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0019] In the utility model, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0020] like Figure 1As shown, the utility model provides a narrow groove adjustable steel support device, including: a steel support 4 and a jack 6, a connecting plate 3 is welded and fixed to the end of one end of the steel support 4, which is used to provide a position for the fixed installation of the jack 6, and the other end of the steel support 4 is provided with a bayonet for clamping on the purlin, and the bottom end of the jack 6 is fixed on the connecting plate 3, and the fixing method is preferably welding.

[0021] The narrow groove adjustable steel support device provided by the utility model realizes the change of the length of the steel support through manual spiral adjustment of the jack, thereby adapting to the adjustment needs of the groove width, so as to adapt to the small net width changes caused by changes in the groove width or deviations in the embedding operation, and the practicality is enhanced; and it can effectively ensure that the axial force of the support reaches the preset value, and the safety is higher.

[0022] In order to increase the contact area between the jack 6 and the purlin, to prevent the contact area from being too small, so that the verticality of the jack 6 in contact with the purlin cannot be directly observed, and to prevent the problem of slipping due to insufficient verticality, the technical solution is further improved as follows: the retractable end of the jack 6 is welded and fixed with a top plate 5, and the area of ​​the top plate is larger than the area of ​​the retractable end of the jack 6. Due to the large area of ​​the top plate 5, the construction personnel can intuitively observe the verticality between the steel support and the purlin through the contact degree between the top plate 5 and the purlin, which can be adjusted in time. At the same time, due to the large area of ​​the top plate 5, when the jack 6 has a small angle deviation, it will not easily fall off the purlin.

[0023] In order to improve the connection strength of the jack 6 and prevent it from popping out due to angle deviation, the technical solution is further improved as follows: a sleeve 7 with at least an open outer end is welded and fixed on the connecting plate 3, and the bottom end of the jack 6 is placed in the sleeve 7, and the bottom end of the jack 6 can be welded and fixed, and the telescopic end of the jack 6 is exposed from the sleeve 7. The length of the sleeve 7 is not longer than the shortest length of the jack 6.

[0024] In order to further reinforce the jack 6 and prevent it from popping out, a further improvement of the technical solution is that a hole sealing plate 2 is welded and fixed at the opening of the sleeve 7, the jack 6 is passed through the hole sealing plate 2, and the jack 6 is welded and fixedly connected to the hole sealing plate 2 at the opening of the hole sealing plate 2.

[0025] In order to improve the verticality of the device when supporting the purlin, the technical solution is further improved as follows: a limit frame 1 is provided on the connecting plate 3, and the limit frame 1 is arranged beside the jack 6. The limit frame 1 plays the same role as the end of the steel support 4, and is used to be set up on the upper part of the purlin, so that the two ends of the device maintain the same verticality in the vertical direction. At the same time, during installation, the purlin plays a role of temporary support for the device, reducing construction processes such as labor and hoisting, and improving construction efficiency.

[0026] As a further improvement, the limiting frame 1 is flat.

[0027] A further improvement is that the limit frame 1 is a frame structure composed of horizontal bars and longitudinal bars, which is used to improve the overall structural strength of the limit frame 1 and can provide effective supporting force when it is erected on the purlin to avoid deformation that causes the device to fall and cause accidents.

[0028] In order to further improve the overall structural strength of the limit frame 1 and prevent it from deforming in the middle part, the technical solution is further improved as follows: a connecting rod 8 is welded and fixed near the middle part of the limit frame 1, and the connecting rod 8 is welded and fixed to the outer wall of the sleeve.

[0029] As a further improvement, a cushion block 9 is provided on the side of the jack 6 at the end of the limiting frame 1.

[0030] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
