Description
Technical field
The present invention relates to a kind of ground in-situ test instrument field, more particularly to a kind of ground in-situ test assembled
Counterweight reaction frame.
Background technology
Traditional ground in-situ test is generally anchored the groups such as bar, propping and I-girder with reaction frame by earth anchor, lengthening
Into.The pressure applied during ground in-situ test passes sequentially through I-girder, propping, anchor bar and native anchor and is transferred to ground by counter-force
Base.More limitation in use be present in earth anchor reaction frame.Such as：Because ground is generally hardened in dense urban,
So that the operation that anchors into of earth anchor is difficult to carry out.Again for example：Superficial soil layer can not then produce enough anchors as more loose to earth anchor
Gu power so that holding force system can not play a role.
The content of the invention
The purpose of this utility model is to provide a kind of ground in-situ test assembled counterweight reaction frame.
The purpose of this utility model is achieved through the following technical solutions：A kind of ground in-situ test assembled counterweight counter-force
Frame, it includes crossbeam, propping, connecting rod and a pair of counterweight platforms；Two connecting rods are equipped with each counterweight platform, are located at
Connected between two connecting rods in same counterweight platform by propping, crossbeam is connected between two proppings.
For prior art, the utility model has the advantage of：
1. the utility model uses counter weight type holding force principle, compared with traditional native anchor reaction frame system, environment is fitted
Answering property is good, there is provided counter-force it is reliable and stable；
2. the utility model uses fabricated construction, the weight of each part is relatively small, is easy to move, suitable at the scene
Operation；
3. the utility model can do any adjustment according to in-situ test instrument size, and test point position, it is applied to
A variety of in-situ test equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic diagram at A-A in Fig. 1；
Fig. 3 is stereogram of the present utility model.
Label declaration：1- crossbeams, 2- proppings, 3- connecting rods, 31- nuts, 4- backing plates, 5- counterweight platforms, 6- bracing pieces.
Embodiment
The utility model content is described in detail with reference to Figure of description and embodiment：
As Figure 1-3：A kind of ground in-situ test assembled counterweight reaction frame, it includes crossbeam 1, propping 2, connected
Extension bar 3 and a pair of counterweight platforms 5；Two connecting rods 3 are equipped with each counterweight platform 5, two in same counterweight platform 5
Connected between root connecting rod 3 by propping 2, crossbeam 1 is connected between two proppings 2.By being connected with upper type, entering
, can be by the holding power needed for ground in-situ test successively through crossbeam 1, propping 2, connecting rod 3, most during row ground in-situ test
It is delivered to eventually in counterweight platform 5.
The crossbeam 1 is connected to the centre position of propping 2.
It is connected by screw bolts between the propping 2 and crossbeam 1.Make between propping 2 and crossbeam 1 power transmission reliable and be easy to tear open
Dress.
The crossbeam 1 is H profile steel.The size of crossbeam should the rigidity according to needed for ground in-situ test be computed determining.
The nut 31 being provided with the top surface of the propping 2, bottom surface, the corresponding region surface of connecting rod 3, which is provided with, is easy to nut
The screw thread of 31 positioning adjustment.By the way that propping 2 is gripped into connecting rod 3 for nut 31；Propping 2 uses the He of nut 31
Screw thread coordinates, and on the one hand makes to be reliably connected between propping 2 and connecting rod 3, is on the other hand easy to propping 2 and connecting rod 3
Dismounting.
The propping 2 includes two shaped steel, and two shaped steel mirror images are located at the both sides of connecting rod 3, passed through between two shaped steel
Bolt is fixed.Propping 2 uses mirror image combining form, mainly realizes that centering is combined with connecting rod 3 for ease of propping 2 so that
Propping 2 will not eccentric force.
The shaped steel is one kind in channel-section steel, square steel tube or I-steel.
Gap location between two shaped steel is provided with backing plate 4.Increase backing plate 4 can improve the globality of propping 2.
The utility model also includes being used for the balancing weight being placed in counterweight platform 5, and the balancing weight is steel plate or coagulation
Native plate.The weight of each balancing weight should be controlled in the range of 2 personnel can move, and the weight of each balancing weight preferably facilitates
The integer of counting, such as 5Kg, 10kg, 25kg etc..
Bracing piece 6 is set between the counterweight platform 5 and connecting rod 3.Connected between increase counterweight platform 5 and connecting rod 3
Intensity.
The connecting rod 3 for length adjustable connecting rod 3.The generally use round steel of connecting rod 3 makes, in connecting rod 3
Middle part sets adjusting means, and adjusting means can use existing conventional structure, such as connecting rod is designed as into locking part
Telescopic type structure, or connecting rod is designed as the bar linkage structure that two screw threads coordinate；Pole length is connected by adjusting, with suitable
Answer different ground elevations.
