TECHNICAL FIELD
[0001] The utility model belongs to the technical field of formwork support, specifically relates to a formwork support structure between small interval wall bodies. BACKGROUND
[0002] In building construction, the commonly used formwork support structure for wall pouring mainly comprises formworks surrounding pouring spaces, vertical columns, horizontal rods and diagonal braces provided outside the formworks, the vertical columns and / or the horizontal rods are attached to the outer walls of the formworks to strengthen the rigidity and strength of the formworks, and the relative positions between the formworks on both sides of the pouring spaces in the thickness direction are fixed by tensioning screws. The upper ends of the diagonal braces support the vertical columns, the horizontal rods or the formworks, and the lower ends of the diagonal brace structures are fixed to the ground base. During pouring, the diagonal braces bear the load of the formworks and the newly poured concrete and transmit the load to the ground base to strengthen the support stability of the formworks. The included angle between the diagonal braces in the above formwork support system and the ground is generally 45°-60°, and the length of the horizontal projection of the diagonal braces is generally 1-2m, that is, the erection of the above formwork support system requires sufficient arrangement space.
[0003] During the construction of hospitals and industrial plants, the building construction of special places such as hospital radiological examination rooms and industrial plant X-ray flaw detection rooms is often involved. Considering the effect of radiation protection and the cost of the protection room, hospitals and some factories use concrete walls and floors with sufficient thickness to prevent radiation leakage. The thickness of such walls and floors is large. Considering the wall thickness of such detection rooms and the external space utilization problem in production and operation, the indoor space of such detection rooms is generally designed to be small enough to meet the equipment operation and personnel operation requirements. For example, a special industrial X-ray flaw detection room with an outer diameter of less than 30cm is a narrow space, the walls on both sides of the steel pipe are parallel to each other and the distance between them is less than 2m, and when pouring the walls on both sides, the distance between the two formworks surrounding different pouring spaces and close to each other is less than 1.5m, the diagonal brace erection space is insufficient, which leads to a large angle between the diagonal brace and the base plate, and even the diagonal brace cannot be erected, which cannot guarantee the stability of the formwork support. In addition, the multiple horizontal rods, vertical columns and diagonal rods in the above formwork support system need to be connected into a whole structure by bolts or buckles on site, which is low in erection efficiency and affects the construction progress.

DETAILED DESCRIPTION
[0029] The utility model will be further explained in connection with the drawings and examples. The examples described below by referring to the drawings are exemplary and are only used to explain the utility model and cannot be understood as the limitation of the utility model.
[0030] As shown in the accompanying drawings Figures 1-5 A formwork support structure between small-pitch walls comprises a first frame body 1, a second frame body 2 and telescopic support rods 3. The first frame body 1 and the second frame body 2 each comprise mutually perpendicular uprights 11 and connecting rods 12.

The telescopic support rods 3 comprise coaxially arranged positive screw rods 31, negative screw rods 32 and adjusting sleeves 33. The positive screw rods 31 and the negative screw rods 32 are symmetrically distributed at the two ends of the adjusting sleeves 33 and are respectively threadedly connected with the inner walls of the adjusting sleeves 33. The axis of the adjusting sleeve 33 is arranged in the second horizontal direction. One end of the positive screw rod 31 away from the adjusting sleeve 33 is connected to the first frame body 1, and one end of the negative screw rod 32 away from the adjusting sleeve 33 is connected to the second frame body 2. The telescopic support rods 3 are provided in a plurality, and the plurality of telescopic support rods 3 are distributed in the up-down direction. The support surfaces of the first frame body 1 and the second frame body 2 refer to the surfaces that abut the formwork.
[0031] When the formwork of the small-pitch wall is erected, the formwork encloses a first pouring space and a second pouring space, the first pouring space is located on the left side of the second pouring space and the two are arranged in a spaced manner. The two groups of formwork between the first pouring space and the second pouring space are parallel and arranged in a spaced manner. Among them, the formwork close to the first pouring space is called left side formwork 91, and the formwork close to the second pouring space is called right side formwork 92, the distance between the left side formwork 91 and the right side formwork 92 is generally less than 2m. The formwork on the left side of the first pouring space and the formwork on the right side of the second pouring space are all supported by the existing combination structure of uprights, horizontal rods and diagonal braces in the background technology. The left side formwork 91 and the formwork on the left side of the first pouring space are fixedly connected by the existing combination structure of tensioning bolts and nuts, and the right side formwork 92 and the formwork on the right side of the second pouring space are also fixedly connected by the existing combination structure of tensioning bolts and nuts.
[0032] When supporting the left side template 91 and the right side template 92, the utility model is used between the left side template 91 and the right side template 92, the positive wire screw rod 31 is perpendicular to the left side template 91 and the right side template 92, rotates a plurality of adjusting sleeves 33 and makes the positive wire screw rod 31 and the reverse wire screw rod 32 far away from each other, increases the length of the telescopic support rod 3, and the positive wire screw rod 31 supports the first frame body 1 to the left, and the reverse wire screw rod 32 supports the second frame body 2 to the right, at this time, the side of the first frame body 1 far away from the second frame body 2 is in abutment with the left side template 91, and the side of the second frame body 2 far away from the first frame body 1 is in abutment with the right side template 92.When the area of the left side template 91 and the right side template 92 is far greater than the support surface of the first frame body 1 and the second frame body 2, a plurality of template support structures are needed to support the template. After the utility model is erected, the first pouring space and the second space are poured with concrete at the same time, the left side template 91 is abutted on the first frame body 1 to the right, the right side template 92 is abutted on the second frame body 2 to the left, the first frame body 1 and the second frame body 2 are abutted on each other through the telescopic support rod 3, the left side template 91 and the right side template 92 are abutted on and supported on each other through the support structure, and the stable support of the left side template 91 and the right side template 92 is further realized. When the formwork is removed, the adjusting sleeve 33 is reversely rotated to make the positive wire screw rod 31 and the reverse wire screw rod 32 close to each other, the length of the telescopic support rod 3 is shortened to make the first frame body 1 and the second frame body 2 close to each other and be separated from the template, and finally the formwork removal operation is carried out.
[0033] The utility model discloses a first frame body 1 left side template 91 face support, through setting up the second frame body 2 right side template 92 face support, through setting up the length adjustable telescopic support rod 3 replaces the inclined support in prior art, through adjusting the length of telescopic support rod 3 makes the first frame body 1 and the second frame body 2 interval adjustable, through the support first frame body 1 and the second frame body 2 makes the first frame body 1 support left side template 91, the second frame body 2 supports right side template 92, and left side template 91 and right side template 92 are abutted on and supported on each other through the utility model, simple structure, stable and reliable, suitable for the support of two templates with insufficient space. Through setting up the adjusting sleeve 33 and the positive wire screw rod 31, the reverse wire screw rod 32 of symmetrical screw connection at its both ends makes the length of telescopic support rod 3 adjustable, and the length adjustment of telescopic support rod 3, the interval adjustment of the first frame body 1 and the second frame body 2 can be realized by rotating the adjusting sleeve 33, which not only facilitates the support and assembly and disassembly of the template, but also makes the utility model applicable to the support of left side template 91 and right side template 92 between two pouring spaces close to each other and different in interval, and is strong in universality, convenient and flexible and cost-saving.
[0034] The first frame body 1 is used for surface supporting the left side formwork 91, increasing the rigidity and strength of the left side formwork 91, and avoiding deformation or even explosion of the left side formwork 91 when pouring concrete into the first pouring space. Similarly, the second frame body 2 is used for surface supporting the right side formwork 92, increasing the rigidity and strength of the right side formwork 92, and avoiding deformation or even explosion of the right side formwork 92 when pouring concrete into the second pouring space. The structures of the first frame body 1 and the second frame body 2 can be the same or different. For the convenience of cutting and processing, preferably, the first frame body 1 and the second frame body 2 are the same in structure and symmetrically arranged at both ends of the telescopic supporting rod 3. For the convenience of carrying and transferring the whole supporting structure, as a further preferred, the bottom surface of the first frame body 1 and the second frame body 2 is further provided with at least two universal casters 7 with brake structures.
[0035] The stand column 11 and the connecting rod 12 on the first frame body 1 and the second frame body 2 can be made of angle steel, channel steel or steel pipe. The angle steel and the channel steel need to be distinguished in direction when connected, and the circular steel pipe has a small contact area when supporting the formwork. Preferably, the stand column 11 and the connecting rod 12 are rectangular steel pipe structures, which are convenient for processing and manufacturing, increase the contact area with the formwork, and more stably and reliably support the formwork. The stand column 11 and the connecting rod 12 can be connected by bolts or welded. Considering that the formwork load is large when pouring concrete, preferably, the stand column 11 and the connecting rod 12 are welded. The number of the connecting rod 12 is determined by the design thickness and height of the wall. The larger the design thickness and height of the wall, the more the number of the connecting rod 12 and the smaller the distance between the two connecting rods 12 close to each other, so as to ensure the reliability of the formwork support and avoid explosion of the wall during pouring.
[0036] The length of the wall body is not the same. If the length of the frame body is too large, the frame body is inconvenient to carry and cannot be applied to the formwork support of the short wall body. If the length of the frame body is too small, a large number of formworks need to be spliced when the formwork support structure supports the formwork of the long wall body, and the erection and arrangement of the formwork support structure are complicated. Preferably, the connecting rod 12 on the first frame body 1 comprises a telescopic sleeve 121, one end of the telescopic sleeve 121 is inserted with a first telescopic rod 122, the other end of the telescopic sleeve 121 is inserted with a second telescopic rod 123, the first telescopic rod 122 and the second telescopic rod 123 are in axial sliding fit with the telescopic sleeve 121; one end of the first telescopic rod 122 away from the telescopic sleeve 121 is connected to one of the stand columns 11, one end of the second telescopic rod 123 away from the telescopic sleeve 121 is connected to another of the stand columns 11 on the first frame body 1; and the axial positioning member 125 for axially positioning the first telescopic rod 122 and the second telescopic rod 123 on the telescopic sleeve 121 is further included. The axial positioning member 125 is adjusted to make the first telescopic rod 122 and the second telescopic rod 123 axially slide relative to the telescopic sleeve 121, the length of the entire connecting rod 12 is adjusted by adjusting the length of the first telescopic rod 122 and the second telescopic rod 123 protruding from the telescopic sleeve 121, and then the axial positioning member 125 is adjusted to axially position the first telescopic rod 122 and the second telescopic rod 123 in the telescopic sleeve 121, so that the length of the connecting rod 12 is adjusted, and the length of the first frame body 1 and the second frame body 2 is also adjusted. The first frame body 1 and the second frame body 2 are the same in structure, and the first frame body 1 and the second frame body 2 need to be synchronously adjusted. The formwork support structure can be used to support the formwork of the wall body with different lengths, and is convenient and flexible.
[0037] The axial positioning member 125 can be a bolt or a pin, but the pin is easy to fall off in actual use, which affects the reliability of the frame structure, therefore, the axial positioning member is generally a bolt. The bolt is threadedly connected to the telescopic sleeve 121, and the end of the bolt away from the nut abuts against the first telescopic rod 122 and the second telescopic rod 123 to position the two telescopic rods on the telescopic sleeve 121. In this positioning structure, once the bolt is slightly loose, the first telescopic rod 122 or the second telescopic rod 123 will slide axially, which affects the stability of the frame. Preferably, the axial positioning member 125 is two screws penetrating the side wall of the telescopic sleeve 121, and the two screws are threadedly connected to the side wall of the telescopic sleeve 121; the side wall of the first telescopic rod 122 and the side wall of the second telescopic rod 123 are both provided with positioning insertion holes 126, the positioning insertion holes 126 are provided in plurality, and the plurality of insertion holes 126 are uniformly distributed along the axial direction of the telescopic sleeve 121; one screw on the telescopic sleeve 121 is inserted into the positioning insertion hole 126 on the first telescopic rod 122, and the other screw on the telescopic sleeve 121 is inserted into the positioning insertion hole 126 on the second telescopic rod 123. This improves the structural stability of the connecting rod 12, the first frame 1 and the second frame 2, and avoids the axial positioning member 125 of the screw structure being slightly loose to affect the axial positioning of the two telescopic rods.
[0038] When the lengths of the first frame 1 and the second frame 2 are too large, the length of the connecting rod 2 is also large, which easily leads to insufficient strength of the first frame 1 and the second frame 2, and there is a potential safety hazard. Preferably, the first frame 1 and the second frame 2 are both provided with a first reinforcing rod 13, and two telescopic sleeves 121 close to each other on the same frame are connected by the first reinforcing rod 13, which improves the strength of the first frame 1 and the second frame 2. As a further improvement, a sliding sleeve 14 axially slidingly matched with the telescopic sleeve 121 is arranged outside the telescopic sleeve 121, the sliding sleeve 14 is provided in two, and the two sliding sleeves 14 are arranged at intervals along the axial direction of the telescopic sleeve 121; the sliding sleeve 14 is connected with a second reinforcing rod 15, and the end of the second reinforcing rod 15 away from the sliding sleeve 14 is fixedly connected to the vertical column 11 close to the sliding sleeve 14. When the connecting rod 12 is shortened, the two sliding sleeves 14 on the telescopic sleeve 121 are close to each other, and vice versa, when the connecting rod 12 is lengthened, the two sliding sleeves 14 on the telescopic sleeve 121 are away from each other. The telescopic sleeve 121 and the vertical column 11 are connected by the sliding sleeve 14 and the second reinforcing rod 15, which further improves the structural stability of the first frame 1 and the second frame 2.
[0039] The number of telescopic support rods 3 is determined by the designed thickness and height of the wall, and the greater the designed thickness and height of the wall, the greater the number of telescopic support rods 3, so as to ensure the support reliability of the formwork and avoid the occurrence of form explosion during the pouring of the wall. The outer thread of the positive screw rod 31 and the outer thread of the reverse screw rod 32 are opposite in direction, and the distance between the positive screw rod 31 and the reverse screw rod 32 can be adjusted by rotating the adjusting sleeve 33, thereby adjusting the total length of the telescopic support rod 3. Preferably, a handle 34 is arranged on the outer side wall of the adjusting sleeve 33, and the handle 34 is provided with two, which are symmetrically arranged on both sides of the adjusting sleeve 33. By pulling the handle 34, the adjusting sleeve 33 is driven to rotate, which is convenient and labor-saving,
[0040] The positive screw rod 31 and the first frame body 1, and the reverse screw rod 32 and the second frame body 2 can be connected by welding, or can be connected by bolts or pins. Preferably, the opposite faces of the first frame body 1 and the second frame body 2 are provided with vertical horizontal guide rails 4; one end of the positive screw rod 31 away from the adjusting sleeve 33 is connected to the guide rail 4 of the first frame body 1 and the two are slidingly fitted in the up-down direction, and one end of the reverse screw rod 32 away from the adjusting sleeve 33 is connected to the guide rail 4 of the second frame body 2 and the two are slidingly fitted in the up-down direction. The telescopic support rod 3 can slide along the length direction of the guide rail 4, that is, the height position of the telescopic support rod 3 can be adjusted, and the height position of the telescopic support rod 3 can be adjusted according to the actual situation on site. When transporting, the telescopic support rod 3 can be removed from the guide rail 4, and then the device is divided into three parts of the first frame body 1, the second frame body 2 and the telescopic support rod 3, which is convenient for transfer and transportation and is not limited by narrow passages.
[0041] The guide rail 4 can be arranged on the stand column 11 or on the telescopic sleeve 121. By rotating the adjusting sleeve 33 to lengthen the telescopic support rod 3, the positive screw rod 31 and the reverse screw rod 32 at both ends of the telescopic support rod 3 are tightly abutted against the guide rail 4, and then the telescopic support rod 3 is positioned on the guide rail 4. Although this embodiment is simple, when someone mistakenly turns the adjusting sleeve 33 to shorten the telescopic support rod 3, the telescopic support rod 3 will suddenly slide down, which has a potential safety hazard. As a further preferred embodiment, the guide rail 4 is connected with a sliding block 5, and the sliding block 5 and the guide rail 4 are slidingly fitted in the up-down direction; the sliding block 5 is threadedly connected with a fastening bolt 54, one end of the fastening bolt 54 away from the nut is tightly abutted against the guide rail 4 to position the sliding block 5 on the guide rail 4; one end of the positive screw rod 31 and the reverse screw rod 32 away from the adjusting sleeve 33 is connected to the sliding block 5 of the guide rail 4. By loosening the fastening bolt 54 to separate the fastening bolt 54 from the guide rail 4 and shorten the telescopic support rod 3, the position of the sliding block 5 on the guide rail 4 can be adjusted, which is safe and reliable.
[0042] Preferably, the guide rail 4 is provided with a lower limit part 6 below, when the slider 5 is located at the lower limit position, the lower limit part 6 supports the slider 5, avoids the slider 5 from the lower end of the guide rail 4 out. The lower limit part 6 can be a screw, a limit block or a latch structure connected to the column 11 by screwing.
