Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a support device and a support system for an underpinning beam. Background Art

[0002] During the renovation and reinforcement of old buildings, it is often necessary to construct underpinning beams. The construction of underpinning beams is relatively complex and involves the following steps: First, an opening for installing the underpinning beam support structure is opened at the location of the underpinning beam wall to be constructed, and the underpinning beam support structure is constructed within the opening. After the underpinning beam support structure is constructed, the remaining underpinning beam wall to be constructed is completely demolished; then, the underpinning beam structure reinforcement is tied; and finally, the underpinning beam formwork is installed and concrete is poured. Because the underpinning beam support structure must bear the static load transmitted by the floor slab, as well as its own weight during the concrete pouring process and the dynamic load during the construction process, the existing underpinning beam support structure construction process is relatively complex and time-consuming. At the same time, because the underpinning beam is operated at a high altitude, the positioning and tying of the underpinning beam structure reinforcement is difficult, and the construction is time-consuming. Utility Model Content

[0003] The purpose of the utility model is to provide a support device and a support system for a replacement beam, so as to solve the shortcomings of the existing replacement beam construction, such as the complex construction process of the replacement beam support structure and the difficulty in positioning and binding the steel bars of the replacement beam structure, and to improve the construction efficiency of the replacement beam.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A support beam support device, characterized in that it comprises a lower support plate and an upper support plate, wherein a first vertical support is fixedly provided between the middle portions of the lower support plate and the upper support plate, and a second vertical support is fixedly provided between the left and right ends of the lower support plate and the upper support plate;

[0006] A plurality of transverse horizontal supports are fixedly connected to the side walls of the second vertical support, and the plurality of transverse horizontal supports are arranged vertically at intervals; vertical limit rods are fixedly connected to the left and right ends of the transverse horizontal supports, and the top ends of the vertical limit rods are located above the top ends of the corresponding transverse horizontal supports.

[0007] The above-mentioned replacement beam support device has the advantages of simple structure and convenient production. When in use, first select or produce a replacement beam support device with a height adaptation according to the height of the replacement beam to be constructed, then open a hole for installing the replacement beam support device at the position of the wall of the replacement beam to be constructed, install the replacement beam support device in the hole, and fill the gap between the bottom surface of the lower support plate and the bottom end surface of the hole and the gap between the top surface of the upper support plate and the top end surface of the hole with mortar or grouting material. In this way, the construction of the replacement beam support structure can be completed quickly.

[0008] After the construction of the underpinning beam support structure is completed, the remaining underpinning beam walls to be constructed will be completely demolished; then the underpinning beam structure reinforcement will be tied. When the underpinning beam structure reinforcement is positioned and tied, the multiple horizontal supports of the underpinning beam support device can provide positioning support for the longitudinal reinforcement of the underpinning beam, greatly reducing the difficulty of positioning and installing the underpinning beam structure reinforcement.

[0009] After the reinforcement of the replacement beam structure is completed, the formwork of the replacement beam will be supported and concrete poured.

[0010] Furthermore, two or more first vertical supports are provided between the middle parts of the lower support plate and the upper support plate.

[0011] Furthermore, two second vertical supports are fixedly provided between the left and right ends of the lower support plate and the upper support plate, and the side walls of the two second vertical supports are fixedly connected with the multiple transverse horizontal supports, and the two ends of the transverse horizontal supports are respectively placed on the outside of the corresponding second vertical supports; an installation groove for installing the longitudinal reinforcement of the replacement beam is formed between the vertical limit rod and the corresponding second vertical support.

[0012] Furthermore, an oblique support is fixedly provided between the lower support plate and the upper support plate.

[0013] Furthermore, the oblique supports are provided between the left end top surface of the lower support plate and the right end bottom surface of the upper support plate, and between the right end top surface of the lower support plate and the left end bottom surface of the upper support plate.

[0014] Furthermore, an anchor connection structure is fixedly provided on the bottom surface of the lower support plate and the top surface of the upper support plate.

[0015] Furthermore, the anchor connection structure is an anchor steel bar.

[0016] Furthermore, the lower support plate, the upper support plate, the first vertical support, the second vertical support, the transverse horizontal support and the vertical limiting rod are all made of metal.

[0017] Based on the same inventive concept, the present invention also provides a support system for an underpinning beam, the structural feature of which is that it includes two or more of the above-mentioned support devices for an underpinning beam, and each of the support devices for an underpinning beam is arranged at intervals along the length direction of the underpinning beam.

[0018] Furthermore, the distance between two adjacent underpinning beam support devices is 1.5m to 3m.

[0019] Compared with the existing technology, the beneficial effects of the present invention are: the present invention solves the shortcomings of the existing underpinning beam construction, such as the complex construction process of the underpinning beam support structure and the difficulty in positioning and binding the steel bars of the underpinning beam structure, thereby improving the construction efficiency of the underpinning beam.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments of the present invention may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0028] like Figures 1-4 As shown, a support beam support device of this embodiment includes a lower support plate 1 and an upper support plate 2, a first vertical support 3 is fixedly provided between the middle parts of the lower support plate 1 and the upper support plate 2, and a second vertical support 4 is fixedly provided between the left and right ends of the lower support plate 1 and the upper support plate 2.

[0029] Multiple horizontal supports 5 are fixedly connected to the side walls of the second vertical supports 4, and the multiple horizontal supports 5 are arranged vertically at intervals. Vertical limit rods 6 are fixedly connected to the left and right ends of the horizontal supports 5, and the top ends of the vertical limit rods 6 are located above the top ends of the corresponding horizontal supports 5.

[0030] The lower support plate 1 , the upper support plate 2 , the first vertical support 3 , the second vertical support 4 , the transverse horizontal support 5 and the vertical limiting rod 6 are all made of steel.

[0031] like Figure 1 As shown, in this embodiment, two first vertical supports 3 are provided between the middle portions of the lower support plate 1 and the upper support plate 2 .

[0032] like Figure 1 and Figure 4 As shown, in this embodiment, two second vertical supports 4 are fixedly disposed between the left and right ends of the lower support plate 1 and the upper support plate 2. The side walls of the two second vertical supports 4 are fixedly connected to the plurality of transverse horizontal supports 5, with the ends of the transverse horizontal supports 5 positioned outside the corresponding second vertical supports 4. Mounting slots 7 for mounting the underpinning beam longitudinal reinforcement 131 are formed between the vertical limiting rods 6 and the corresponding second vertical supports 4. This facilitates the fixed installation of the underpinning beam longitudinal reinforcement 131 and improves the installation efficiency of the underpinning beam structural reinforcement 13.

[0033] like Figure 1-Figure 2 As shown, in this embodiment, an inclined support 8 is further fixedly disposed between the lower support plate 1 and the upper support plate 2. Specifically, the inclined support 8 is disposed between the left end top surface of the lower support plate 1 and the right end bottom surface of the upper support plate 2, as well as between the right end top surface of the lower support plate 1 and the left end bottom surface of the upper support plate 2. The inclined support 8 is made of steel. This improves the rigidity of the underpinning beam support device and ensures its stability during use.

[0034] like Figures 1-4 As shown, in this embodiment, the bottom surface of the lower support plate 1 and the top surface of the upper support plate 2 are both fixedly provided with an anchor connection structure 9. Specifically, the anchor connection structure 9 is a plurality of rows of longitudinal anchor steel bars.

[0035] like Figure 1-Figure 5 As shown, this embodiment also provides a support system for an underpinning beam, which includes two or more of the above-mentioned support devices for the underpinning beam, each of which is spaced apart along the length of the underpinning beam. The spacing between two adjacent support devices for the underpinning beam is 1.5m to 3m.

[0036] like Figure 5 As shown, the steps of assisting the underpinning beam construction by the underpinning beam support device of this embodiment are as follows:

[0037] First, make two supporting beam support devices of suitable height according to the height of the supporting beam to be constructed, and the height of the supporting beam support device is slightly smaller than the height of the supporting beam to be constructed. Then, open two holes for installing the supporting beam support devices at intervals at the position of the wall of the supporting beam to be constructed, install the supporting beam support device in each hole, install templates (with reserved casting openings) on the outer periphery of the gap between the bottom surface of the lower support plate 1 and the bottom end surface of the hole, and on the outer periphery of the gap between the top surface of the upper support plate 2 and the top end surface of the hole, and fill the gap between the bottom surface of the lower support plate 1 and the bottom end surface of the hole, and between the top surface of the upper support plate 2 and the top end surface of the hole with grouting material.

[0038] After the construction of the two underpinning beam support devices is completed, the remaining underpinning beam walls to be constructed will be completely demolished; then the underpinning beam structural steel bars 13 will be tied. When the underpinning beam structural steel bars 13 are positioned and tied, the multiple transverse horizontal supports 5 of the underpinning beam support device can provide positioning support for the underpinning beam longitudinal steel bars 131, which greatly reduces the difficulty of positioning and installing the underpinning beam structural steel bars 13 and improves the construction quality of the underpinning beam.

[0039] After the steel bars 13 of the underpinning beam structure are tied, the formwork of the underpinning beam is finally supported and concrete is poured.

[0040] The contents described in the above embodiments should be understood as these embodiments are only used to more clearly illustrate the present invention, and are not used to limit the scope of the present invention. After reading the present invention, various equivalent modifications to the embodiments by those skilled in the art fall within the scope defined by the claims attached to the present invention.
